Summary: PostgreSQL support for Dovecot
Dovecot is an IMAP and POP3 server for Linux and UNIX-like systems,
written primarily with security in mind. Although it is written in C,
it uses several coding techniques to avoid most of the common pitfalls.

Dovecot can work with standard mbox and maildir formats and is fully
compatible with UW-IMAP and Courier IMAP servers as well as mail
clients accessing the mailboxes directly.

This package holds the files needed for PostgreSQL support.

Changelog

* Tue Jun 14 2022 Michael Ströder <michael@stroeder.com>
  - update to 2.3.19.1
    * doveadm deduplicate: Non-duplicate mails were deleted. v2.3.19 regression.
    * auth: Crash would occur when iterating multiple backends.
      Fixes: Panic: file userdb-blocking.c: line 125 (userdb_blocking_iter_next): assertion failed: (ctx->conn != NULL)
* Tue May 10 2022 Arjen de Korte <suse+build@de-korte.org>
  - update to 2.3.19 and pigeonhole 0.5.19
    Dovecot 2.3.19
    + Added mail_user_session_finished event, which is emitted when the mail
      user session is finished (e.g. imap, pop3, lmtp). It also includes
      fields with some process statistics information.
      See https://doc.dovecot.org/admin_manual/list_of_events/ for more
      information.
    + Added process_shutdown_filter setting. When an event matches the filter,
      the process will be shutdown after the current connection(s) have
      finished. This is intended to reduce memory usage of long-running imap
      processes that keep a lot of memory allocated instead of freeing it to
      the OS.
    + auth: Add cache hit indicator to auth passdb/userdb finished events.
      See https://doc.dovecot.org/admin_manual/list_of_events/ for more
      information.
    + doveadm deduplicate: Performance is improved significantly.
    + imapc: COPY commands were sent one mail at a time to the remote IMAP
      server. Now the copying is buffered, so multiple mails can be copied
      with a single COPY command.
    + lib-lua: Add a Lua interface to Dovecot's HTTP client library. See
      https://doc.dovecot.org/admin_manual/lua/ for more information.
    - auth: Cache lookup would use incorrect cache key after username change.
    - auth: Improve handling unexpected LDAP connection errors/hangs.
      Try to fix up these cases by reconnecting to the LDAP server and
      aborting LDAP requests earlier.
    - auth: Process crashed if userdb iteration was attempted while auth-workers
      were already full handling auth requests.
    - auth: db-oauth2: Using %{oauth2:name} variables caused unnecessary
      introspection requests.
    - dict: Timeouts may have been leaked at deinit.
    - director: Ring may have become unstable if a backend's tag was changed.
      It could also have caused director process to crash.
    - doveadm kick: Numeric parameter was treated as IP address.
    - doveadm: Proxying can panic when flushing print output. Fixes
      Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed:
      (ioloop == current_ioloop).
    - doveadm sync: BROKENCHAR was wrongly changed to '_' character when
      migrating mailboxes. This was set by default to %, so any mailbox
      names containing % characters were modified to "_25".
    - imapc: Copying or moving mails with doveadm to an imapc mailbox could
      have produced "Error: Syncing mailbox '[...]' failed" Errors. The
      operation itself succeeded but attempting to sync the destination
      mailbox failed.
    - imapc: Prevent index log synchronization errors when two or more imapc
      sessions are adding messages to the same mailbox index files, i.e.
      INDEX=MEMORY is not used.
    - indexer: Process was slowly leaking memory for each indexing request.
    - lib-fts: fts header filters caused binary content to be sent to the
      indexer with non-default configuration.
    - doveadm-server: Process could hang in some situations when printing
      output to TCP client, e.g. when printing doveadm sync state.
    - lib-index: dovecot.index.log files were often read and parsed entirely,
      rather than only the parts that were actually necessary. This mainly
      increased CPU usage.
    - lmtp-proxy: Session ID forwarding would cause same session IDs being
      used when delivering same mail to multiple backends.
    - log: Log prefix update may have been lost if log process was busy.
      This could have caused log prefixes to be empty or in some cases
      reused between sessions, i.e. log lines could have been logged for the
      wrong user/session.
    - mail_crypt: Plugin crashes if it's loaded only for some users. Fixes
      Panic: Module context mail_crypt_user_module missing.
    - mail_crypt: When LMTP was delivering mails to both recipients with mail
      encryption enabled and not enabled, the non-encrypted recipients may
      have gotten mails encrypted anyway. This happened when the first
      recipient was encrypted (mail_crypt_save_version=2) and the 2nd
      recipient was not encrypted (mail_crypt_save_version=0).
    - pop3: Session would crash if empty line was sent.
    - stats: HTTP server leaked memory.
    - submission-login: Long credentials, such as OAUTH2 tokens, were refused
      during SASL interactive due to submission server applying line length
      limits.
    - submission-login: When proxying to remote host, authentication was not
      using interactive SASL when logging in using long credentials such as
      OAUTH2 tokens. This caused authentication to fail due to line length
      constraints in SMTP protocol.
    - submission: Terminating the client connection with QUIT command after
      mail transaction is started with MAIL command and before it is
      finished with DATA/BDAT can cause a segfault crash.
    - virtual: doveadm search queries with mailbox-guid as the only parameter
      crashes: Panic: file virtual-search.c: line 77 (virtual_search_get_records):
      assertion failed: (result != 0)
    Pigeonhole v0.5.19
    * This release is done to maintain parity with dovecot 2.3.19 release,
      so it does not contain any news-worthy changes.
* Thu Feb 03 2022 Michael Ströder <michael@stroeder.com>
  - update to 2.3.18 and pigeonhole to 0.5.18
    * removed obsolete mail-cache-bigendian.diff
    Dovecot 2.3.18
    * Removed mail_cache_lookup_finished event. This event wasn't especially
      useful, but it increased CPU usage significantly.
    * fts: Don't index inline base64 encoded content in FTS indexes using
      the generic tokenizer. This reduces the FTS index sizes by removing
      input that is very unlikely to be searched for. See
      https://doc.dovecot.org/configuration_manual/fts/tokenization for
      details on how base64 is detected. Only applies when using libfts.
    * lmtp: Session IDs are now preserved through proxied connections, so
      LMTP sessions can be tracked. This slightly changes the LMTP session
      ID format by appending ":Tn" (transaction), ":Pn" (proxy connection)
      and ":Rn" (recipient) counters after the session ID prefix.
    + Events now have "reason_code" field, which can provide a list of
      reasons why the event is happening. See
      https://doc.dovecot.org/admin_manual/event_reasons/
    + New events are added. See https://doc.dovecot.org/admin_manual/list_of_events/
    + fts: Added fts_header_excludes and fts_header_includes settings to
      specify which headers to index. See
      https://doc.dovecot.org/settings/plugin/fts-plugin#plugin-fts-setting-fts-header-excludes
      for configuration details.
    + fts: Initialize the textcat language detection library only once per
      process. This can reduce CPU usage if fts_languages setting has multiple
      languages listed and service indexer-worker { service_count } isn't 1.
      Only applies when using libfts.
    + lib-storage: Reduced CPU usage significantly for some operations that
      accessed lots of emails (e.g. fetching all flags in a folder, SORT, ...)
    + lib: DOVECOT_PREREQ() - Add micro version which enables compiling
      external plugins against different versions of Dovecot.
    + lmtp: Added new lmtp_verbose_replies setting that makes errors sent to
      the LMTP client much more verbose with details about why exactly
      backend proxy connections or commands are failing.
    + submission: Support implicit SASL EXTERNAL with
      submission_client_workarounds=implicit-auth-external. This allows
      automatically logging in when SSL client certificate is present.
    - *-login: Statistics were disabled if stats process connection was lost.
    - auth: Authentication master user login fails with SCRAM-* SASL mechanisms.
    - auth: With auth_cache_verify_password_with_worker=yes, passdb extra
      fields in the auth cache got lost.
    - doveadm: Fixed crash if zlib_save_level setting was specified,
      but zlib_save was unset. v2.3.15 regression.
    - doveadm: Proxying can panic when flushing print output. v2.3.17
      regression. Fixes:
      Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed:
      (ioloop == current_ioloop)
    - doveadm: stats add --group-by parameter didn't work.
    - fts: Using email-address fts tokenizer could result in excessive memory
      usage with garbage email input. This could cause the indexer-worker
      processes to fail due to reaching the VSZ memory size limit.
      Only applies when using libfts.
    - imap: A SEARCH command timing out while fts returns indexes may timeout
      returning "NO [SERVERBUG]", while it should return "NO [INUSE]" instead.
    - imap: LIST-EXTENDED doesn't return STATUS for all folders. Sending
      LIST .. RETURN (SUBSCRIBED STATUS (...)) did not return STATUS for
      folders that are not subscribed when they have a child folder that is
      subscribed as mandated by IMAP RFCs.
    - imapc: Mailbox vsize calculation crashed with
      Panic: file index-mailbox-size.c: line 344 (index_mailbox_vsize_hdr_add_missing):
      assertion failed: (mails_left > 0)
    - indexer: If indexer-worker crashes, the request it was processing gets
      stuck in the indexer process. This stops indexing for the folder until
      indexer process is restarted. v2.3.14 regression.
    - indexer: Process was slowly leaking memory for each indexing request.
    - lib-event: Unnamed events were wrongly filtered out for event/metric
      filters like "event=abc OR something_independent_of_event_name".
    - lib-index: 64-bit big endian CPUs handle last_used field in
      dovecot.index.cache wrong.
    - lib-ssl-iostream: Fix buggy OpenSSL error handling without assert-crashing.
      If there is no error available, log it as an error instead of crashing.
      The previous fix for this in v2.3.11 was incomplete. Fixes
      Panic: file istream-openssl.c: line 51 (i_stream_ssl_read_real):
      assertion failed: (errno != 0)
    - lmtp: Out-of-memory issues can happen when proxying large messages to
      LMTP backend servers that accept the message data too slow.
    - master: HAProxy header parsing has read buffer overflow if provided
      header size is invalid. This happens only if inet_listener
      { haproxy=yes } is configured and only if the remote IP address is in
      haproxy_trusted_networks.
    - old_stats: Plugin kept increasing memory usage, which became
      noticeable with long-running imap sessions.
    - stats: Dynamically adding same metric multiple times causes multiple stats.
    - submission-login: Authentication does not accept OAUTH2 token (or
      other very long credentials) because it considers the line to be too long.
    - submission-login: Process can crash if HELO is pipelined with an
      invalid domain.
    - submission-proxy: Don't use SASL-IR if it would make the AUTH command
      line longer than 512 bytes.
    - submission: Service would crash if relay server authentication failed.
    - virtual: FTS search in a virtual folder could crash if there are
      duplicate mailbox GUIDs. This mainly happened when user had both INBOX
      and INBOX/INBOX folders and the namespace prefix was INBOX/. Fixes
      Panic: file hash.c: line 252 (hash_table_insert_node):
      assertion failed: (opcode == HASH_TABLE_OP_UPDATE)
    - virtual: If mailbox opening fails, the backend mailbox is leaked and
      process crashes when client disconnects. Fixes
      Panic: file mail-user.c: line 232 (mail_user_deinit):
      assertion failed: ((*user)->refcount == 1)
    - virtual: Searching headers in virtual folders didn't always use
      full-text search indexes, if fts_enforced=no or body.
    Pigeonhole v0.5.18
    - duplicate: Users without a home directory can crash with Sieve when
      using duplicate database. v2.3.17 regression.
    - imapsieve: When mail was expunged when processing imapsieve events, a
      crash could occur. Fixes Panic: file mail-index-map.c:
      line 558 (mail_index_map_lookup_seq_range): assertion failed: (first_uid > 0)
    - managesieve-login: Proxy didn't support forwarding the forward_* passdb fields.
    - redirect: Sieve would crash if redirect after keep-equivalent action failed.
    - sieve: Interpreter crashes when the Sieve index extension is used with
      index zero.
    - vnd.dovecot.filter: Envelope sender string may become corrupted when
      Sieve scripts are using vnd.dovecot.filter. This could end up
      corrupting mbox's From line and return wrong envelope sender string in
* Wed Feb 02 2022 Dominique Leuenberger <dimstar@opensuse.org>
  - Fix dovecot-2.3.0-dont_use_etc_ssl_certs.patch: Align the
    certificate path/filenames to /etc/ssl/private/*.crt, which
    happens to match what the patch also does for mkcert.sh
    (boo#1193909).
  - Rebase dovecot-2.3.0-better_ssl_defaults.patch
* Thu Dec 16 2021 Fabian Vogt <fvogt@suse.com>
  - Update dovecot-2.3.0-dont_use_etc_ssl_certs.patch to also adjust
    the path in the 10-ssl.conf example (boo#1193758)
  - Rebase dovecot-2.3.0-better_ssl_defaults.patch
* Tue Dec 07 2021 Michael Ströder <michael@stroeder.com>
  - update to 2.3.17.1 and pigeonhole to 0.5.17.1
  - rebased dovecot-2.3.0-better_ssl_defaults.patch
    Dovecot 2.3.17.1
    - dsync: Add back accidentically removed parameters.
    - lib-ssl-iostream: Fix assert-crash when OpenSSL returned syscall error
      without errno.
    - master: Dovecot failed to start if ssl_ca was too large.
    Dovecot 2.3.17
    * Dovecot now logs a warning if time seems to jump forward at least
      100 milliseconds.
    * dict: Lines logged by the dict process now contain the dict name as
      the prefix.
    * lib-index: mail_cache_fields, mail_always_cache_fields and
      mail_never_cache_fields now verifies that the listed header names are
      valid. Especially the UTF8 "–" character has sometimes been wrongly
      used instead of the ASCII "-".
    + *-login: Added login_proxy_rawlog_dir setting to capture
      rawlogs between proxy and backend.
    + dict: The server process now keeps the last 10 idle dict backends
      cached for maximum of 30 seconds. Practically this acts as a
      connection pool for dict-redis and dict-ldap. Note that this doesn't
      affect dict-sql, because it already had its own internal cache.
    + doveadm: New stats add/remove commands added to support changing the
      metrics configuration on runtime.
    + lazy_expunge: Added lazy_expunge_exclude settings to disable
      lazy_expunge for specific folders. \Special-use flags can be used as
      folder names.
    + lib-lua: Added a new helper function dovecot.restrict_global_variables()
      to disable or enable defining new global variables.
    - LAYOUT=index List index rebuild was missing.
    - LAYOUT=index: Duplicate GUIDs were not detected.
    - acl: When using acl_ignore_namespace Dovecot attempted to access or
      create dovecot-acl-list even when the namespace should have been
      ignored. For virtual namespaces this could have yielded errors about
      "Read-only file system" or "Permission denied".
    - auth: Setting the "master" passdb field to empty value would
      cause proxying to fail with an authentication error.
      Now an empty "master" field is ignored.
    - doveadm-server: Duplicate error lines were sent for failed commands.
      This didn't normally cause visible problems, except when using
      wildcards in usernames or -A parameter to go through multiple users.
    - doveadm-server: Logs written by doveadm-server were often missing log
      prefixes, especially mail_log_prefix for mail commands. Logs sent to
      doveadm TCP client were also missing log prefixes.
    - doveadm: v2.3 regression: batch command always crashes.
    - doveadm: v2.3.11 regression: Commands failed if ssl_cert or
      ssl_key files weren't readable by the user running doveadm, even
      though doveadm didn't actually use these settings
    - imap-hibernate: Process may crash at deinit:
      Panic: file ioloop.c: line 928 (io_loop_destroy): assertion failed:
      (ioloop->cur_ctx == NULL).
    - imap: Using imap_fetch_failure=no-after can cause assert-crash
      with some IMAP commands if reading the mail fails (e.g. wrong cached
      mail size). Fixes:
      Panic: file index-mail-headers.c: line 198 (index_mail_parse_header_init):
      assertion failed: (!mail->data.header_parser_initialized)
    - imap: v2.3.10 regression: When using INDEXPVT to enable private
      \Seen flags (for shared or public namespaces) the STORE command did
      not send untagged replies for the \Seen flag changes.
    - imap: v2.3.15 regression: If PREVIEW/SNIPPET is not the final FETCH
      option in the command, the IMAP FETCH response is broken.
    - imap: v2.3.15 regression: MOVE command leaks mailbox if it can't be
      opened and crashes at deinit:
      Panic: file mail-user.c: line 229 (mail_user_deinit): assertion failed:
      ((*user)->refcount == 1).
    - imapc: Copying nonexistent mail via imapc could have crashed. Fixes:
      Panic: file mail-storage.c: line 2385 (mailbox_transaction_commit_get_changes):
      assertion failed: (ret < 0 || seq_range_count(&changes_r->saved_uids) == save_count ||
      array_count(&changes_r->saved_uids) == 0).
    - indexer: v2.3.15 regression: Process crashes if indexer-client
      disconnects while it's waiting for command reply. This happened for
      example if IMAP SEARCH triggered long fts indexing and the IMAP
      client disconnected while waiting for the reply.
    - indexer: v2.3.15 regression: Process may have crashed in some situations.
    - indexer: v2.3.15 regression: indexer-worker processes may not have
      reached the process_limit in some situations, possibly even using just
      one indexer-worker process even though there were many indexing
      requests queued.
    - lib-compression: Reading lz4 compressed mdbox mails may crash. Fixes:
      Panic: file istream.c: line 345 (i_stream_read_memarea):
      assertion failed: (!stream->blocking).
    - lib-compression: bench-compress crashes due to xz being read-only.
    - lib-lua: Fix linking libdict_lua for non-GNU linkers when Lua support
      is disabled.
    - lib-mail: There was no limit on how large an email header name could be.
      Processable header names are now limited to 1000 bytes.
    - lib-oauth2: Dovecot disallowed JWT tokens if their validity time was
      older than token creation time (nbf < iat).
    - lib-storage: Reduce memory footprint of certain storage operations.
    - lib-storage: When listing mailboxes with storage name escape
      characters (^ or .) as part of the mailbox name, the listing could
      show corrupted mailbox names. Due to an issue in handling escaped
      parent folders, the listing of other mailbox names would become
      corrupted by prepending parts of the previously listed mailboxes
      parent folder as prefix to the actual mailbox names. The corruption
      can occur when using LAYOUT=INDEX and maildir or obox, or when using
      the listescape plugin.
    - mail-crypt: Fix "-O" argument for "doveadm mailbox cryptokey password"
      command to be a boolean, and not expect a string.
    - submission-login: Add support for not authenticating to next hop in
      submission proxying.
    - submission-login: EHLO was not sent again after XCLIENT when doing
      submission proxying.
    - virtual: Mailboxes do not correctly detect underlying mailboxes
      getting re-created even though they have a different UIDVALIDITY or
      GUID.
    Pigeonhole v0.5.17
    - duplicate: The Sieve duplicate test is prone to false negatives when
      the user receives many e-mails concurrently, meaning that duplicate
      deliveries can still occur.
    - fileinto: v2.3.16 regression: Sieve delivery crashes if mail is
      delivered to non-existing and existing folder.
    - imap-filter-sieve: v2.3.15 regression: The CPU limits on Sieve
      execution are too easily exceeded in IMAP context (the IMAPSieve and
      FILTER=SIEVE capabilities). Changed the default to unlimited CPU time
      for IMAP context, since similar excessive resource usage can be caused
      by other means as well. The CPU limits on Sieve scripts executed at
      LDA/LMTP delivery are still enforced by default.
    - redirect:  The Sieve redirect action has protections against users
      triggering mail loops. Unfortunately, the detection of a redirect mail
      loop sometimes causes the message to get lost if no other Sieve action
      is applied that delivers the message somewhere else.
    - redirect: v2.3.16 regression: With certain Sieve scripts if redirect
      fails due to temporary failure, the lmtp process may crash after the
      delivery. Fixes:
      Panic: file mail-user.c: line 229 (mail_user_deinit):
      assertion failed: ((*user)->refcount == 1).
* Tue Aug 10 2021 Michael Ströder <michael@stroeder.com>
  - added back-port fix mail-cache-bigendian.diff
  - update to 2.3.16 and pigeonhole to 0.5.16:
    Dovecot 2.3.16
    * Any unexpected exit() will now result in a core dump. This can
      especially help notice problems when a Lua script causes exit(0).
    * auth-worker process is now restarted when the number of auth
      requests reaches service auth-worker { service_count }. The default
      is still unlimited.
    + Event improvements: Added data_stack_grow event and http-client
      category. See https://doc.dovecot.org/admin_manual/list_of_events/
    + oauth2: Support RFC 7628 openid-configuration element. This allows
      clients to support OAUTH2 for any server, not just a few hardcoded
      servers like they do now. See openid_configuration_url setting in
      dovecot-oauth2.conf.ext.
    + mysql: Single statements are no longer enclosed with BEGIN/COMMIT.
    + dovecot-sysreport --core supports multiple core files now and does
      not require specifying the binary path.
    + imapc: When imap_acl plugin is loaded and imapc_features=acl is used,
      IMAP ACL commands are proxied to the remote server. See
      https://doc.dovecot.org/configuration_manual/mail_location/imapc/
    + dict-sql now supports the "UPSERT" syntax for SQLite and PostgreSQL.
    + imap: If IMAP client disconnects during a COPY command, the copying
      is aborted, and changes are reverted. This may help to avoid many
      email duplicates if client disconnects during COPY and retries it
      after reconnecting.
    - master process was using 100% CPU if service attempted to create more
      processes due to process_min_avail, but process_limit was already
      reached. v2.3.15 regression.
    - Using attachment detection flags wrongly logged unnecessary "Failed
      to add attachment keywords" errors. v2.3.13 regression.
    - IMAP QRESYNC: Expunging UID 1 mail resulted in broken VANISHED
      response, which could have confused IMAP clients. v2.3.13 regression.
    - imap: STORE didn't send untagged replies for \Seen changes for
      (shared) mailboxes using INDEXPVT. v2.3.10 regression.
    - rawlog_dir setting would not log input that was pipelined after
      authentication command.
    - Fixed potential infinite looping with autoexpunging.
    - Log event exporter: Truncate long fields to 1000 bytes
    - LAYOUT=index: ACL inheritance didn't work when creating mailboxes
    - Event filters: Unquoted '?' wildcard caused a crash at startup
    - fs-metawrap: Fix to handling zero sized files
    - imap-hibernate: Fixed potential crash at deinit.
    - acl: dovecot-acl-list files were written for acl_ignore_namespaces
    - program-client (used by Sieve extprograms, director_flush_socket)
      may have missed status response from UNIX and network sockets,
      resulting in unexpected failures.
    Pigeonhole v0.5.16
    * .dovecot.sieve.log file now includes year in the header.
    * Change Sieve script result execution to delay definitive action
      execution to the end of a successful Sieve script execution session.
      This is part of an effort to solve problems with the Sieve duplicate
      test. As a side-effect, some rare temporary-error cases yield
      different results, in which partial failure is more likely.
* Tue Jun 22 2021 Marcus Rueckert <mrueckert@suse.de>
  - use lua 5.1 for sle12
* Mon Jun 21 2021 Michael Ströder <michael@stroeder.com>
  - update to 2.3.15 and pigeonhole to 0.5.15:
    * security fixes for CVE-2021-29157, CVE-2021-33515, and CVE-2020-28200
    * rebased patch dovecot-2.3.0-better_ssl_defaults.patch
    * removed obsolete back-port patches
      allow-tls1.3-only.patch and openssl-cnf-default_bits-2048.patch
    * require lua53-devel for build
    Dovecot 2.3.15
    * CVE-2021-29157: Dovecot does not correctly escape kid and azp fields in
      JWT tokens. This may be used to supply attacker controlled keys to
      validate tokens, if attacker has local access.
    * CVE-2021-33515: On-path attacker could have injected plaintext commands
      before STARTTLS negotiation that would be executed after STARTTLS
      finished with the client.
    * Disconnection log messages are now more standardized across services.
      They also always now start with "Disconnected" prefix.
    * Dovecot now depends on libsystemd for systemd integration.
    * Removed support for Lua 5.2. Use version 5.1 or 5.3 instead.
    * config: Some settings are now marked as "hidden". It's discouraged to
      change these settings. They will no longer be visible in doveconf
      output, except if they have been changed or if doveconf -s parameter
      is used. See https://doc.dovecot.org/settings/advanced/ for details.
    * imap-compress: Compression level is now algorithm specific.
      See https://doc.dovecot.org/settings/plugin/compress-plugin/
    * indexer-worker: Convert "Indexed" info logs to an event named
      "indexer_worker_indexing_finished". See
      https://doc.dovecot.org/admin_manual/list_of_events/#indexer-worker-indexing-finished
    + Add TSLv1.3 support to min_protocols.
    + Allow configuring ssl_cipher_suites. (for TLSv1.3+)
    + acl: Add acl_ignore_namespace setting which allows to entirely ignore
      ACLs for the listed namespaces.
    + imap: Support official RFC8970 preview/snippet syntax. Old methods of
      retrieving preview information via IMAP commands ("SNIPPET and PREVIEW
      with explicit algorithm selection") have been deprecated.
    + imapc: Support INDEXPVT for imapc storage to enable private
      message flags for cluster wide shared mailboxes.
    + lib-storage: Add new events: mail_opened, mail_expunge_requested,
      mail_expunged, mail_cache_lookup_finished. See
      https://doc.dovecot.org/admin_manual/list_of_events/#mail
    + zlib, imap-compression, fs-compress: Support compression levels that
      the algorithm supports. Before, we would allow hardcoded value between
      1 to 9 and would default to 6. Now we allow using per-algorithm value
      range and default to whatever default the algorithm specifies.
    - *-login: Commands pipelined together with and just after the authenticate
      command cause these commands to be executed twice. This applies to all
      protocols that involve user login, which currently comprises of imap,
      pop3, submisision and managesieve.
    - *-login: Processes are supposed to disconnect the oldest non-logged in
      connection when process_limit was reached. This didn't actually happen
      with the default "high-security mode" (with service_count=1) where each
      connection is handled by a separate process.
    - *-login: When login process reaches client/process limits, oldest
      client connections are disconnected. If one of these was still doing
      anvil lookup, this caused a crash. This could happen only if the login
      process limits were very low or if the server was overloaded.
    - Fixed building with link time optimizations (-flto).
    - auth: Userdb iteration with passwd driver does not always return all
      users with some nss drivers.
    - dsync: Shared INBOX not synced when "mail_shared_explicit_inbox" was
      disabled. If a user has a shared mailbox which is another user's INBOX,
      dsync didn't include the mailbox in syncing unless explicit naming is
      enabled with "mail_shared_explicit_inbox" set to "yes".
    - dsync: Shared namespaces were not synced with "-n" flag.
    - dsync: Syncing shared INBOX failed if mail_attribute_dict was not set.
      If a user has a shared mailbox that is another user's INBOX, dsync
      failed to export the mailbox if mail attributes are disabled.
    - fts-solr, fts-tika: Using both Solr FTS and Tika may have caused HTTP
      requests to assert-crash: Panic: file http-client-request.c: line 1232
      (http_client_request_send_more): assertion failed: (req->payload_input != NULL)
    - fts-tika: 5xx errors returned by Tika server as indexing failures.
      However, Tika can return 5xx for some attachments every time.
      So the 5xx error should be retried once, but treated as success if it
      happens on the retry as well. v2.3 regression.
    - fts-tika: v2.3.11 regression: Indexing messages with fts-tika may have
      resulted in Panic: file message-parser.c: line 802 (message_parser_deinit_from_parts):
      assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input))
    - imap: SETMETADATA could not be used to unset metadata values.
      Instead NIL was handled as a "NIL" string. v2.3.14 regression.
    - imap: IMAP BINARY FETCH crashes at least on empty base64 body:
      Panic: file index-mail-binary.c: line 358 (blocks_count_lines):
      assertion failed: (block_count == 0 || block_idx+1 == block_count)
    - imap: If IMAP client using the NOTIFY command was disconnected while
      sending FETCH notifications to the client, imap could crash with
      Panic: Trying to close mailbox INBOX with open transactions.
    - imap: Using IMAP COMPRESS extension can cause IMAP connection to hang
      when IMAP commands are >8 kB long.
    - imapc: If remote server sent BYE but didn't immediately disconnect, it
      could cause infinite busy-loop.
    - lib-index: Corrupted cache record size in dovecot.index.cache file
      could have caused a crash (segfault) when accessing it.
    - lib-oauth2: JWT token time validation now works correctly with
      32-bit systems.
    - lib-ssl-iostream: Checking hostnames against an SSL certificate was
      case-sensitive.
    - lib-storage: Corrupted mime.parts in dovecot.index.cache may have
      resulted in Panic: file imap-bodystructure.c: line 206 (part_write_body):
      assertion failed: (text == ((part->flags & MESSAGE_PART_FLAG_TEXT) != 0))
    - lib-storage: Index rebuilding (e.g. via doveadm force-resync) didn't
      preserve the "hdr-pop3-uidl" header. Because of this, the next pop3
      session could have accessed all of the emails' metadata to read their
      POP3 UIDL (opening dbox files).
    - listescape: When using the listescape plugin and a shared namespace
      the plugin didn't work properly anymore resulting in errors like:
      "Invalid mailbox name: Name must not have '/' character."
    - lmtp: Connection crashes if connection gets disconnected due to
      multiple bad commands and the last bad command is BDAT.
    - lmtp: The Dovecot-specific LMTP parameter XRCPTFORWARD was blindly
      forwarded by LMTP proxy without checking that the backend has support.
      This caused a command parameter error from the backend if it was
      running an older Dovecot release. This could only occur in more complex
      setups where the message was proxied twice; when the proxy generated
      the XRCPTFORWARD parameter itself the problem did not occur, so this
      only happened when it was forwarded.
    - lmtp: The LMTP proxy crashes with a panic when the remote server
      replies with an error while the mail is still being forwarded through
      a DATA/BDAT command.
    - lmtp: Username may have been missing from lmtp log line prefixes when
      it was performing autoexpunging.
    - master: Dovecot would incorrectly fail with haproxy 2.0.14 service
      checks.
    - master: Systemd service: Dovecot announces readiness for accepting
      connections earlier than it should. The following environment variables
      are now imported automatically and can be omitted from
      import_environment setting: NOTIFY_SOCKET LISTEN_FDS LISTEN_PID.
    - master: service { process_min_avail } was launching processes too
      slowly when master was forking a lot of processes.
    - util: Make the health-check.sh example script POSIX shell compatible.
    Pigeonhole 0.5.15
    * CVE-2020-28200: Sieve interpreter is not protected against abusive
      scripts that claim excessive resource usage. Fixed by limiting the
      user CPU time per single script execution and cumulatively over
      several script runs within a configurable timeout period. Sufficiently
      large CPU time usage is summed in the Sieve script binary and execution
      is blocked when the sum exceeds the limit within that time. The block
      is lifted when the script is updated after the resource usage times out.
    * Disconnection log messages are now more standardized across services.
      They also always now start with "Disconnected" prefix.
    - managesieve: Commands pipelined together with and just after the
      authenticate command cause these commands to be executed twice.
* Fri May 14 2021 Fabian Vogt <fvogt@suse.com>
  - Add patch to fix insecure default openssl.cnf (boo#1184552):
    * openssl-cnf-default_bits-2048.patch
  - Use %autosetup
* Thu Mar 04 2021 Michael Ströder <michael@stroeder.com>
  - update to 2.3.14 and pigeonhole to 0.5.14
    * removed obsolete fix-timeval_cmp_margin-for-32bit-systems.patch
    Dovecot 2.3.14
    * Added new aliases for some variables. Usage of the old ones is possible,
      but discouraged. (These were partially added already to v2.3.13.)
      See https://doc.dovecot.org/configuration_manual/config_file/config_variables/
      for more information.
    * Optimize imap/pop3/submission/managesieve proxies to use less CPU at
      the cost of extra memory usage.
    * Remove autocreate, expire, snarf and mail-filter plugins.
    * Remove cydir storage driver.
    * Remove XZ/LZMA write support. Read support will be removed in future release.
    * doveadm -D: Add timestamps to debug output even when LOG_STDERR_TIMESTAMP
      environment variable is not set. Timestamp format is taken from
      log_timestamp setting.
    * If BROKENCHAR or listescape plugin is used, the escaped folder names
      may be slightly different from before in some situations. This is
      unlikely to cause issues, although caching clients may redownload the
      folders.
    * imapc: It now enables BROKENCHAR=~ by default to escape remote folder
      names if necessary. This also means that if there are any '~'
      characters in the remote folder names, they will be visible as "~7e".
    * imapc: When using local index files folder names were escaped on
      filesystem a bit differently. This affects only if there are folder
      names that actually require escaping, which isn't so common. The old
      style folders will be automatically deleted from filesystem.
    * stats: Update exported metrics to be compliant with OpenMetrics standard.
    + doveadm: Add an optional '-p' parameter to metadata list command. If
      enabled, "/private", and "/shared" metadata prefixes will be prepended
      to the keys in the list output.
    + doveconf: Support environment variables in config files. See
      https://doc.dovecot.org/configuration_manual/config_file/config_file_syntax/#environment-variables
      for more details.
    + indexer-worker: Change indexer to disconnect from indexer-worker
      after each request. This allows service indexer-worker's service_count &
      idle_kill settings to work. These can be used to restart indexer-worker
      processes once in a while to reduce their memory usage.
    - auth: "nodelay" with various authentication mechanisms such as apop
      and digest-md5 crashed AUTH process if authentication failed.
    - auth: Auth lua script generating an error triggered an assertion
      failure: Panic: file db-lua.c: line 630 (auth_lua_call_password_verify):
      assertion failed: (lua_gettop(script->L) == 0).
    - configure: Fix libunwind detection to work on other than x86_64 systems.
    - doveadm-server: Process could crash if logging was done outside command
      handling. For example http-client could have done debug logging
      afterwards, resulting in either segfault or Panic:
      file http-client.c: line 642 (http_client_context_close):
      assertion failed: (cctx->clients_list == NULL).
    - dsync: Folder name escaping with BROKENCHAR didn't work completely
      correctly. This especially caused problems with dsync-migrations using
      imapc where some of the remote folder names may not have been accessible.
    - dsync: doveadm sync + imapc doesn't always sync all mails when doing
      an incremental sync (-1), which could lead to mail loss when it's used
      for migration. This happens only when GUIDs aren't used (i.e.
      imapc without imapc_features=guid-forced).
    - fts-tika: When tika server returns error, some mails cause Panic:
      file message-parser.c: line 802 (message_parser_deinit_from_parts):
      assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input))
    - lib-imap: imapc parsing illegal BODYSTRUCTUREs with NILs could have
      resulted in crashes. This exposed that Dovecot was wrongly accepting
      atoms in "nstring" handling. Changed the IMAP parsing to be more
      strict about this now.
    - lib-index: If dovecot.index.cache has corrupted message size, fetching
      BODY/BODYSTRUCTURE may cause assert-crash:
      Panic: file index-mail.c: line 1140 (index_mail_parse_body_finish):
      assertion failed: (mail->data.parts != NULL).
    - lib-index: Minor error handling and race condition fixes related to
      rotating dovecot.index.log. These didn't usually cause problems,
      unless the log files were rotated rapidly.
    - lib-lua: Lua scripts using coroutines or lua libraries using coroutines
      (e.g., cqueues) panicked.
    - Message PREVIEW handled whitespace wrong so first space would get
      eaten from between words.
    - FTS and message PREVIEW (snippet) parsed HTML &entities case-sensitively.
    - lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE
      was written in a way that may have caused confusion for IMAP clients
      and also Dovecot itself when parsing it. The truncated part is now
      written out using application/octet-stream MIME type.
    - lib-oauth2: HS512 and HS384 JWT token algorithms crash when you try to
      use them: Panic: file hmac.c: line 26 (hmac_init): assertion failed:
      (meth->context_size <= MAC_MAX_CONTEXT_SIZE).
    - event filters: NOT keyword did not have the correct associativity.
      NOT a AND b were getting parsed as NOT (a AND b) instead of
      (NOT a) AND b.
    - Ignore ECONNRESET when closing socket. This avoids logging useless
      errors on systems like FreeBSD.
    - event filters: event filter syntax error may lead to Panic:
      file event-filter.c: line 137 (event_filter_parse): assertion failed:
      (state.output == NULL)
    - lib: timeval_cmp_margin() was broken on 32-bit systems. This could
      potentially have caused HTTP timeouts to be handled incorrectly.
    - log: instance_name wasn't used as syslog ident by the log process.
    - master: After a service reached process_limit and client_limit, it
      could have taken up to 1 second to realize that more client connections
      became available. During this time client connections could have been
      unnecessarily rejected and a warning logged:
      Warning: service(...): process_limit (...) reached, client connections are being dropped
    - stats: Crash would occur when generating openmetrics data for metrics
      using aggregating functions.
    - stats: Event filters comparing against empty strings crash the stats
      process.
    Pigeonhole 0.5.14
    * IMAP FILTER command: cmd-filter-sieve - Do not allow NIL as
      script name argument.
* Thu Feb 04 2021 Arjen de Korte <suse+build@de-korte.org>
  - add BuildRequires openssl-devel >= 1.0.1

    Fix timeval_cmp_margin for 32-bit systems
    https://github.com/dovecot/core/pull/149
* Mon Jan 04 2021 Arjen de Korte <suse+build@de-korte.org>
  - update to 2.3.13 and pigeonhole to 0.5.13
    Dovecot 2.3.13
    * CVE-2020-24386: Specially crafted command can cause IMAP hibernate to
      allow logged in user to access other people's emails and filesystem
      information.
    * Metric filter and global event filter variable syntax changed to a
      SQL-like format. See
      https://doc.dovecot.org/configuration_manual/event_filter/
    * auth: Added new aliases for %{variables}. Usage of the old ones is
      possible, but discouraged.
    * auth: Removed RPA auth mechanism, SKEY auth mechanism, NTLM auth
      mechanism and related password schemes.
    * auth: Removed passdb-sia, passdb-vpopmail and userdb-vpopmail.
    * auth: Removed postfix postmap socket
    + auth: Added new fields for auth server events. These fields are now
      also available for all auth events. See
      https://doc.dovecot.org/admin_manual/list_of_events/#authentication-server
      for details.
    + imap-hibernate: Added imap_client_hibernated, imap_client_unhibernated
      and imap_client_unhibernate_retried events. See
      https://doc.dovecot.org/admin_manual/list_of_events/ for details.
    + lib-index: Added new mail_index_recreated event. See
      https://doc.dovecot.org/admin_manual/list_of_events/#mail-index-recreated
    + lib-sql: Support TLS options for cassandra driver. This requires
      cpp-driver v2.15 (or later) to work reliably.
    + lib-storage: Missing $HasAttachment / $HasNoAttachment flags are now
      added to existing mails if mail_attachment_detection_option=add-flags
      and it can be done inexpensively.
    + login proxy: Added login_proxy_max_reconnects setting (default 3) to
      control how many reconnections are attempted.
    + login proxy: imap/pop3/submission/managesieve proxying now supports
      reconnection retrying on more than just connect() failure. Any error
      except a non-temporary authentication failure will result in reconnect
      attempts.
    - auth: Lua passdb/userdb leaks stack elements per call, eventually
      causing the stack to become too deep and crashing the auth or
      auth-worker process.
    - auth: SASL authentication PLAIN mechanism could be used to trigger
      read buffer overflow. However, this doesn't seem to be exploitable in
      any way.
    - auth: v2.3.11 regression: GSSAPI authentication fails because dovecot
      disallows NUL bytes for it.
    - dict: Process used too much CPU when iterating keys, because each key
      used a separate write() syscall.
    - doveadm-server: Crash could occur if logging was done outside command
      handling. For example http-client could have done debug logging
      afterwards, resulting in either segfault or
      Panic: file http-client.c: line 642 (http_client_context_close):
      assertion failed: (cctx->clients_list == NULL).
    - doveadm-server: v2.3.11 regression: Trying to connect to doveadm server
      process via starttls assert-crashed if there were no ssl=yes listeners:
      Panic: file master-service-ssl.c: line 22 (master_service_ssl_init):
      assertion failed: (service->ssl_ctx_initialized).
    - fts-solr: HTTP requests may have assert-crashed:
      Panic: file http-client-request.c: line 1232
      (http_client_request_send_more):
      assertion failed: (req->payload_input != NULL)
    - imap: IMAP NOTIFY could crash with a segmentation fault due to a bad
      configuration that causes errors. Sending the error responses to the
      client can cause the segmentation fault. This can for example happen
      when several namespaces use the same mail storage location.
    - imap: IMAP NOTIFY used on a shared namespace that doesn't actually
      exist (e.g. public namespace for a nonexistent user) can crash with a
      panic:
      Panic: Leaked view for index /tmp/home/asdf/mdbox/dovecot.list.index:
      Opened in (null):0
    - imap: IMAP session can crash with QRESYNC extension if many changes
      are done before asking for expunged mails since last sync.
    - imap: Process might hang indefinitely if client disconnects after
      sending some long-running commands pipelined, for example FETCH+LOGOUT.
    - lib-compress: Mitigate crashes when configuring a not compiled in
      compression. Errors with compression configuration now distinguish
      between not supported and unknown.
    - lib-compression: Using xz/lzma compression in v2.3.11 could have
      written truncated output in some situations. This would result in
      "Broken pipe" read errors when trying to read it back.
    - lib-compression: zstd compression could have crashed in some situations:
      Panic: file ostream.c: line 287 (o_stream_sendv_int): assertion
      failed: (!stream->blocking)
    - lib-dict: dict client could have crashed in some rare situations when
      iterating keys.
    - lib-http: Fix several assert-crashes in HTTP client.
    - lib-index: v2.3.11 regression: When mails were expunged at the same
      time as lots of new content was being saved to the cache (e.g. cache
      file was lost and is being re-filled) a deadlock could occur with
      dovecot.index.cache / dovecot.index.log.
    - lib-index: v2.3.11 regression: dovecot.index.cache file was being
      purged (rewritten) too often when it had a field that hadn't been
      accessed for over 1 month, but less than 2 months. Every cache file
      change caused a purging in this situation.
    - lib-mail: MIME parts were not returned correctly by Dovecot MIME parser.
      Regression caused by fixing CVE-2020-12100.
    - lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE
      was written in a way that may have caused confusion for both IMAP
      clients and Dovecot itself when parsing it. The truncated part is now
      written out using application/octet-stream MIME type.
    - lib-mail: v2.3.11 regression: Mail delivery / parsing crashed when the
      10000th MIME part was message/rfc822 (or if parent was multipart/digest):
      Panic: file message-parser.c: line 167 (message_part_append):
      assertion failed: (ctx->total_parts_count <= ctx->max_total_mime_parts).
    - lib-oauth2: Dovecot incorrectly required oauth2 server introspection
      reply to contain username with invalid token.
    - lib-ssl-iostream, lib-dcrypt: Fix building with OpenSSL that has
      deprecated APIs disabled.
    - lib-storage: When mail's size is different from the cached one (in
      dovecot.index.cache or Maildir S=size in the filename), this is
      handled by logging "Cached message size smaller/larger than expected"
      error. However, in some situations this also ended up crashing with:
      Panic: file istream.c: line 315 (i_stream_read_memarea):
      assertion failed: (old_size <= _stream->pos - _stream->skip).
    - lib-storage: v2.3 regression: Copying/moving mails was taking much more
      memory than before. This was mainly visible when copying/moving
      thousands of mails in a single transaction.
    - lib-storage: v2.3.11 regression: Searching messages assert-crashed
      (without FTS): Panic: file message-parser.c: line 174
      (message_part_finish):
      assertion failed: (ctx->nested_parts_count > 0).
    - lib: Dovecot v2.3 moved signal handlers around in ioloops,
      causing more CPU usage than in v2.2.
    - lib: Fixed JSON parsing: '\' escape sequence may have wrongly resulted
      in error if it happened to be at read boundary. Any NUL characters and
      '\u0000' will now result in parsing error instead of silently
      truncating the data.
    - lmtp, submission: Server may hang if SSL client connection disconnects
      during the delivery. If this happened repeated, it could have ended
      up reaching process_limit and preventing any further lmtp/submission
      deliveries.
    - lmtp: Proxy does not always properly log TLS connection problems as
      errors; in some cases, only a debug message is logged if enabled.
    - lmtp: The LMTP service can hang when commands are pipelined. This can
      particularly occur when one command in the middle of the pipeline fails.
      One example of this occurs for proxied LMTP transactions in which the
      final DATA or BDAT command is pipelined after a failing RCPT command.
    - login-proxy: The login_source_ips setting has no effect, and therefore
      the proxy source IPs are not cycled through as they should be.
    - master: Process was using 100% CPU in some situations when a broken
      service was being throttled.
    - pop3-login: POP3 login would fail with "Input buffer full" if the
      initial response for SASL was too long.
    - stats: Crash would occur when generating openmetrics data for metrics
      using aggregating functions.
    Pigeonhole 0.5.13
    - duplicate: The test was handled badly in a multiscript (sieve_before,
      sieve_after) scenario in which an earlier script in the sequence with
      a duplicate test succeeded, while a later script caused a runtime
      failure. In that case, the message is recorded for duplicate tracking,
      while the message may not actually have been delivered in the end.
    - editheader: Sieve interpreter entered infinite loop at startup when
      the "editheader" configuration listed an invalid header name. This
      problem can only be triggered by the administrator.
    - relational: The Sieve relational extension can cause a segfault at
      compile time. This is triggered by invalid script syntax. The segfault
      happens when this match type is the last argument of the test command.
      This situation is not possible in a valid script; positional arguments
      are normally present after that, which would prevent the segfault.
    - sieve: For some Sieve commands the provided mailbox name is not
      properly checked for UTF-8 validity, which can cause assert crashes at
      runtime when an invalid mailbox name is encountered. This can be
      caused by the user by writing a bad Sieve script involving the
      affected commands ("mailboxexists", "specialuse_exists").
      This can be triggered by the remote sender only when the user has
      written a Sieve script that passes message content to one of the
      affected commands.
    - sieve: Large sequences of 8-bit octets passed to certain Sieve
      commands that create or modify message headers that allow UTF-8 text
      (vacation, notify and addheader) can cause the delivery or IMAP
      process (when IMAPSieve is used) to enter a memory-consuming
      semi-infinite loop that ends when the process exceeds its memory
      limits. Logged in users can cause these hangs only for their own
      processes.

  - update to 2.3.11.3 and pigeonhole to 0.5.11 (boo#1174920 boo#1174922 boo#1174923)
    Dovecot 2.3.11.3
    - pop3-login: Login didn't handle commands in multiple IP packets properly.
      This mainly affected large XCLIENT commands or a large SASL initial
      response parameter in the AUTH command.
    - pop3: pop3_deleted_flag setting was broken, causing:
      Panic: file seq-range-array.c: line 472 (seq_range_array_invert):
      assertion failed: (range[count-1].seq2 <= max_seq)
    Dovecot 2.3.11.2
    - auth: Lua passdb/userdb leaks stack elements per call, eventually
      causing the stack to become too deep and crashing the auth or
      auth-worker process.
    - lib-mail: v2.3.11 regression: MIME parts not returned correctly by
      Dovecot MIME parser.
    - pop3-login: Login would fail with "Input buffer full" if the initial
      response for SASL was too long.
    Dovecot 2.3.11
    * CVE-2020-12100: Parsing mails with a large number of MIME parts could
      have resulted in excessive CPU usage or a crash due to running out of
      stack memory.
    * CVE-2020-12673: Dovecot's NTLM implementation does not correctly check
      message buffer size, which leads to reading past allocation which can
      lead to crash.
    * CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an
      address that has the empty quoted string as local-part causes the lmtp
      service to crash.
    * CVE-2020-12674: Dovecot's RPA mechanism implementation accepts
      zero-length message, which leads to assert-crash later on.
    * Events: Fix inconsistency in events. See event documentation in
      https://doc.dovecot.org.
    * imap_command_finished event's cmd_name field now contains "unknown"
      for unknown commands. A new "cmd_input_name" field contains the
      command name exactly as it was sent.
    * lib-index: Renamed mail_cache_compress_* settings to mail_cache_purge_*.
      Note that these settings are mainly intended for testing and usually
      shouldn't be changed.
    * events: Renamed "index" event category to "mail-index".
    * events: service:<name> category is now using the name from
      configuration file.
    * dns-client: service dns_client was renamed to dns-client.
    * log: Prefixes generally use the service name from configuration file.
      For example dict-async service will now use
      "dict-async(pid): " log prefix instead of "dict(pid): "
    * *-login: Changed logging done by proxying to use a consistent prefix
      containing the IP address and port.
    * *-login: Changed disconnection log messages to be slightly clearer.
    + dict: Add events for dictionaries.
    + lib-index: Finish logging with events.
    + oauth2: Support local validation of JWT tokens.
    + stats: Add support for dynamic histograms and grouping. See
      https://doc.dovecot.org/configuration_manual/stats/.
    + imap: Implement RFC 8514: IMAP SAVEDATE
    + lib-index: If a long-running transaction (e.g. SORT/FETCH on a huge
      folder) adds a lot of data to dovecot.index.cache file, commit those
      changes periodically to make them visible to other concurrent sessions
      as well.
    + stats: Add OpenMetrics exporter for statistics. See
      https://doc.dovecot.org/configuration_manual/stats/openmetrics/.
    + stats: Support disabling stats-writer socket by setting
      stats_writer_socket_path="".
    - auth-worker: Process keeps slowly increasing its memory usage and
      eventually dies with "out of memory" due to reaching vsz_limit.
    - auth: Prevent potential timing attacks in authentication secret
      comparisons: OAUTH2 JWT-token HMAC, imap-urlauth token, crypt() result.
    - auth: Several auth-mechanisms allowed input to be truncated by NUL
      which can potentially lead to unintentional issues or even successful
      logins which should have failed.
    - auth: When auth policy returned a delay, auth_request_finished event
      had policy_result=ok field instead of policy_result=delayed.
    - auth: auth process crash when auth_policy_server_url is set to an
      invalid URL.
    - dict-ldap: Crash occurs if var_expand template expansion fails.
    - dict: If dict client disconnected while iteration was still running,
      dict process could have started using 100% CPU, although it was still
      handling clients.
    - doveadm: Running doveadm commands via proxying may hang, especially
      when doveadm is printing a lot of output.
    - imap: "MOVE * destfolder" goes to a loop copying the last mail to the
      destination until the imap process dies due to running out of memory.
    - imap: Running "UID MOVE 1:* Trash" on an empty folder goes to infinite
      loop.
    - imap: SEARCH doesn't support $.
    - lib-compress: Buffer over-read in zlib stream read.
    - lib-dns: If DNS lookup times out, lib-dns can cause crash in calling
      process.
    - lib-index: Fixed several bugs in dovecot.index.cache handling that
      could have caused cached data to be lost.
    - lib-index: Writing to >=1 GB dovecot.index.cache files may cause
      assert-crashes:
      Panic: file mail-index-util.c: line 37 (mail_index_uint32_to_offset):
      assertion failed: (offset < 0x40000000)
    - lib-ssl-iostream: Fix buggy OpenSSL error handling without
      assert-crashing. If there is no error available, log it as an error
      instead of crashing:
      Panic: file iostream-openssl.c: line 599 (openssl_iostream_handle_error):
      assertion failed: (errno != 0)
    - lib-ssl-iostream: ssl_key_password setting did not work.
    - submission: A segfault crash may occur when the client or server
      disconnects while a non-transaction command like NOOP or VRFY is still
      being processed.
    - virtual: Copying/moving mails with IMAP into a virtual folder assert-crashes:
      Panic: file cmd-copy.c: line 152 (fetch_and_copy): assertion failed:
      (copy_ctx->copy_count == seq_range_count(&copy_ctx->saved_uids))
    Pigeonhole 0.5.11
    * managesieve: managesieve_max_line_length setting is now a "size" type
      instead of just number of bytes. This allows using e.g. "64k" as the
      value.
    - lib-sieve: When folding white space is used in the Message-ID header,
      it is not stripped away correctly before the message ID value is used,
      causing e.g. garbled log lines at delivery.
* Tue May 19 2020 Marcus Rueckert <mrueckert@suse.de>
  - update tls 1.3 patch to allow building with tls 1.0
* Mon May 18 2020 Michael Ströder <michael@stroeder.com>
  - update to 2.3.10.1 with security fixes for
    * CVE-2020-10957: lmtp/submission: A client can crash the server by
      sending a NOOP command with an invalid string parameter.
      (boo#1171457)
    * CVE-2020-10958: lmtp/submission: Sending many invalid or unknown
      commands can cause the server to access freed memory, which can lead
      to a server crash. (boo#1171458)
    * CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an
      address that has the empty quoted string as local-part causes the
      lmtp service to crash. (boo#1171456)
* Wed Apr 29 2020 Marcus Rueckert <mrueckert@suse.de>
  - add allow-tls1.3-only.patch:
    Allow setting TLSv1.3 as minimum TLS version
    https://github.com/dovecot/core/pull/126
* Fri Mar 06 2020 Arjen de Korte <suse+build@de-korte.org>
  - update to 2.3.10 and pigeonhole to 0.5.10
    Dovecot 2.3.10
    * Disable retpoline migitations by default. These can cause severe
      performance regressions, so they should be only enabled when
      applicable.
    * IMAP MOVE now commits transactions in batches of 1000 mails. This
      helps especially with lazy_expunge when moving a lot of mails. It
      mainly avoids situations where multiple IMAP sessions are running the
      same MOVE command and duplicating the mails in the lazy_expunge folder.
      With this change there can still be some duplication, but the MOVE
      always progresses forward. Also if the MOVE fails at some point, the
      changes up to the last 1000 mails are still committed instead of
      rolled back. Note that the COPY command behavior hasn't changed,
      because it is required by IMAP standard to be an atomic operation.
    * IMAP EXPUNGE and CLOSE now expunges mails in batches of 1000 mails.
      This helps especially with lazy_expunge when expunging a lot of mails
      (e.g. millions) to make sure that the progress always moves forward
      even if the process is killed.
    * Autoexpunging now expunges mails in batches of 1000 mails. This helps
      especially with lazy_expunge when expunging a lot of mails
      (e.g. millions) to make sure that the progress always moves forward
      even if the process is killed.
    + Add tool for generating sysreport called dovecot-sysreport.
      This generates a bundle of information usually needed for support
      requests.
    + Add support for the new IMAP \Important SPECIAL-USE flag (RFC 8457).
    + Add metric { group_by } setting. This allows automatically creating
      new metrics based on the fields you want to group statistics by.
      NOTE: This feature is considered experimental and syntax is subject
      to change in future release.
    + auth: Support SCRAM-SHA-256 authentication mechanism.
    + imap: Support the new IMAP STATUS=SIZE extension.
    + Use TCP_QUICKACK to reduce latency for some TCP connections.
    + quota-status: Made the service more robust against erroneous use with
      Postfix ACL policies other than smtpd_recipient_restrictions.
    + Add "revision" field support to imap_id_send setting. Using
      "revision *" will send in IMAP ID command response the short commit
      hash of the Dovecot git source tree HEAD (same as in dovecot --version).
    + IMAP ENVELOPE includes now all addresses when there are multiple
      headers (From, To, Cc, etc.) The standard way of having multiple
      addresses is to just list them all in a single header. It's
      non-standard to have multiple headers. However, since MTAs allow these
      mails to pass through and different software may handle them in
      different ways, it's better from security point of view to show all
      the addresses.
    + Event filters now support using "field_name=" to match a field that
      doesn't exist or has an empty value. For example use "error=" to match
      only events that didn't fail.
    - acl: INBOX ACLs shouldn't apply for IMAP GETMETADATA/SETMETADATA
      commands.
    - cassandra: CASS_ERROR_SERVER_WRITE_FAILURE error should also be
      treated as "uncertain write failure".
    - dict-redis: Using quota_clone configured with dict-redis could have
      crashed when Redis responded slowly.
    - fts-solr: The XML response parser fails to parse large/chunked responses
      correctly. This leads to spurious parse errors, most notably: "Error:
      fts_solr: received invalid uid '0'".
    - imap-hibernate: Communication trouble with imap-master leads to
      segfault.
    - imap-hibernate: Unhibernation retrying wasn't working.
    - imap: Fixed auth lookup privilege problem when imap process was reused
      and user was being un-hibernated.
    - Fix potential crash when copying/moving mails within the same folder.
      This happened only when there were a lot of fields in dovecot.index.cache.
    - lib-index: Recreating dovecot.index.cache file could have crashed when
      merging bitmask fields.
    - lib-index: Using public/shared folders with INDEXPVT configured to use
      private \Seen flags, trying to search seen/unseen in an empty folder
      crashes with segfault.
    - lib-mail: Large base64-encoded mails weren't decoded properly.
      This could have affected searching/indexing mails and message snippet
      generation.
    - lib-mail: Message with only quoted text could have caused message
      snippet to ignore its 200 character limit and return the entire
      message. This was added also to dovecot.index.cache file, which
      increased disk space and memory usage unnecessarily.
      v2.3.9.2 regression (previous versions cached the quoted snippet as
      empty). In a large mail quoted text could have become wrongly added
      to the snippet, possibly mixed together with non-quoted text.
    - lib-smtp: client could have assert-crashed if STARTTLS handshake
      finished earlier than usually.
    - lib-ssl-iostream: remove -static flag for lib-ssl-iostream linking to
      prevent a compile issue.
    - lib-storage: Mailbox synchronization may have assert-crashed in some
      rare situations.
    - lib-storage: mdbox didn't preserve date.saved with dsync.
    - lib: Don't require EAI_{ADDRFAMILY,NODATA}, breaks FreeBSD
    - master: Some services could respawn unthrottled if they crash during
      startup.
    - push-notification: Do not send push_notification_finished event if
      nothing was done. This happens when mail transaction is started and
      ended with no changes.
    - quota-status: Addresses with special characters in the local part caused
      problems in the interaction between Postfix and Dovecot. Postfix sent
      its own internal representation in the recipient field, while Dovecot
      expected a valid RFC5321 mailbox address.
    - submission-login: SESSION was not correctly encoded field for the
      XCLIENT command. Particularly, a '+' character introduced by the
      session ID's Base64 encoding causes problems.
    - submission: Fix submission_max_mail_size to work correctly on 32-bit
      systems.
    - submission: Trusted connections crashed in second connection's EHLO
      if submission-login { service_count } is something else than 1 (which
      is the default).
    - submission: XCLIENT command was never used in the protocol exchange
      with the relay MTA when submission_backend_capabilities is configured,
      even when the relay MTA was properly configured to accept the XCLIENT
      command.
    Pigeonhole 0.5.10
    * imap_sieve_filter: Change result action logging to include IMAP UID
    - vacation: Addresses were compared case-sensitively.
* Wed Feb 26 2020 Dominique Leuenberger <dimstar@opensuse.org>
  - Update dovecot-2.3.0-dont_use_etc_ssl_certs.patch: since we

  - update to 2.3.9 and pigeonhole to 0.5.9
    Dovecot 2.3.9
    * Changed several event field names for consistency and to avoid
      conflicts in parent-child event relationships:
    * SMTP server command events: Renamed "name" to "cmd_name"
    * Events inheriting from a mailbox: Renamed "name" to "mailbox"
    * Server connection events have only "remote_ip", "remote_port",
      "local_ip" and "local_port".
    * Removed duplicate "client_ip", "ip" and "port".
    * Mail storage events: Removed "service" field.
      Use "service:<name>" category instead.
    * HTTP client connection events: Renamed "host" to "dest_host" and
      "port" to "dest_port"
    * auth: Drop Postfix socketmap support. It hasn't been working
      with recent Postfix versions for a while now.
    * push-notification-lua: The "subject" field is now decoded to UTF8
      instead of kept as MIME-encoded.
    + push-notification-lua: Added new "from_address", "from_display_name",
      "to_address" and "to_display_name" fields. The display names are
      decoded to UTF8.
    + Added various new fields to existing events.
      See http://doc.dovecot.net/admin_manual/list_of_events.html
    + Add lmtp_add_received_header setting. It can be used to prevent LMTP
      from adding "Received:" headers.
    + doveadm: Support SSL/STARTTLS for proxied doveadm connections based on
      doveadm_ssl setting and proxy ssl/tls settings.
    + Log filters support now "service:<name>", which matches all events for
      the given service. It can also be used as a category.
    + lib: Use libunwind to get abort backtraces with function names
      where available.
    + lmtp: When the LMTP proxy changes the username (from passdb lookup)
      add an appropriate ORCPT parameter.
    - lmtp: Add lmtp_client_workarounds setting to implement workarounds for
      clients that send MAIL and RCPT commands with additional spaces before
      the path and for clients that omit <> brackets around the path.
      See example-config/conf.d/20-lmtp.conf.
    - lda/lmtp: Invalid MAIL FROM addresses were rejcted too aggressively.
      Now mails from addresses with unicode characters are delivered, but
      their Return-Path header will be <> instead of the given MAIL FROM
      address.
    - lmtp: The lmtp_hdr_delivery_address setting is ignored.
    - imap: imap_command_finished event's "args" and "human_args" parameters
      were always empty.
    - mbox: Seeking in zlib and bzip2 compressed input streams didn't work
      correctly.
    - imap-hibernate: Process crashed when client got destroyed while it was
      attempted to be unhibernated, and the unhibernation fails.
    - *-login: Proxying may have crashed if SSL handshake to the backend
      failed immediately. This was unlikely to happen in normal operation.
    - *-login: If TLS handshake to upstream server failed during proxying,
      login process could crash due to invalid memory access.
    - *-login: v2.3 regression: Using SASL authentication without initial
      response may have caused SSL connections to hang. This happened often
      at least with PHP's IMAP library.
    - *-login: When login processes are flooded with authentication attempts
      it starts logging errors about "Authentication server sent unknown id".
      This is still expected. However, it also caused the login process to
      disconnect from auth server and potentially log some user's password
      in the error message.
    - dict-sql: SQL prepared statements were not shared between sessions.
      This resulted in creating a lot of prepared statements, which was
      especially inefficient when using Cassandra backend with a lot of
      Cassandra nodes.
    - auth: auth_request_finished event didn't have success=yes parameter
      set for successful authentications.
    - auth: userdb dict - Trying to list users crashed.
    - submission: Service could be configured to allow anonymous
      authentication mechanism and anonymous user access.
    - LAYOUT=index: Corrupted dovecot.list.index caused folder creation to
      panic.
    - doveadm: HTTP server crashes if request target starts with double "/".
    - dsync: Remote dsync started hanging if the initial doveadm
      "dsync-server" command was sent in the same TCP packet as the
      following dsync handshake. v2.3.8 regression.
    - lib: Several "input streams" had a bug that in some rare situations
      might cause it to access freed memory. This could lead to crashes or
      corruption.
      The only currently known effect of this is that using zlib plugin with
      external mail attachments (mail_attachment_dir) could cause fetching
      the mail to return a few bytes of garbage data at the beginning of the
      header. Note that the mail wasn't saved corrupted, but fetching it
      caused corrupted mail to be sent to the client.
    - lib-storage: If a mail only has quoted content, use the quoted text
      for generating message snippet (IMAP PREVIEW) instead of returning
      empty snippet.
    - lib-storage: When vsize header was rebuilt, newly calculated message
      sizes were added to dovecot.index.cache instead of being directly
      saved into vsize records in dovecot.index.
    - lib: JSON generator was escaping UTF-8 characters unnecessarily.
    Pigeonhole 0.5.8
    + Added events for Sieve and ManageSieve, see
      https://doc.dovecot.org/admin_manual/list_of_events/#pigeonhole
    + Pigeonhole: Implement the Sieve "special-use" extension described in
      RFC 8579.
    - duplicate: Test only compared the handles which would cause
      different values to be cached as the same duplicate test. Fix to also
      compare the actual hashes.
    - imap_sieve_filter: IMAP FILTER Command had various bugs in error
      handling. Errors may have been duplicated for each email, errors
      may have been missing entirely, command tag and ERRORS/WARNINGS
      parameters were swapped.

  - Disable Link Time Optimization (LTO) (boo#1156301)
* Tue Oct 08 2019 Michael Ströder <michael@stroeder.com>
  - update to 2.3.8 and pigeonhole to 0.5.8
    Dovecot 2.3.8
    + Added mail_delivery_started and mail_delivery_finished events, see
      https://doc.dovecot.org/admin_manual/list_of_events/ for details.
    + dsync-replication: Don't replicate users who have "noreplicate" extra
      field in userdb.
    + doveadm service status: Show total number of processes created.
    + When logging to syslog, use instance_name setting's value for the
      ident. This commonly is added as a log prefix.
    + Base64 encoding/decoding code was rewritten with additional features.
      It shouldn't cause any user visible changes.
    - v2.3.7 regression: If a folder only receives new mails without any
      other mail access, dovecot.index.log keeps growing forever and
      dovecot.index keeps being rewritten for every mail delivery.
    - dsync-replication may lose keywords after syncing mails restored from
      another replica. This only happened if the mail only had keywords and
      no system flags.
    - event filters: Non-textual event fields could not be filtered using
      wildcards.
    - auth: Scope parameter was missing from OAuth password grant
      request.
    - doveadm client-server communication may hang in some situations.
      It is also using unnecessarily small TCP/IP packet sizes.
    - doveadm who and kick did not flush protocol output correctly.
    - imap: SETMETADATA with literal value would delete the metadata value
      instead of updating it.
    - imap: When client issues FETCH PREVIEW (LAZY=FUZZY) command, the
      caching decisions should be updated so that newly saved mails will
      have the preview cached.
    - With mail_nfs_index=yes and/or mail_nfs_storage=yes setuid/setgid
      permission bits in some files may have become dropped with some NFS
      servers. Changed NFS flushing to now use chmod() instead of chown().
    - quota: warnings did not work if quota root was noenforcing
    - acl: Global ACL file ignored the last line if it didn't end with LF.
    - doveadm stats dump: With JSON formatter output numbers using the
      number type instead of as strings
    - lmtp_proxy: Ensure that real_* variables are correctly set when using
      lmtp_proxy.
    - event exporter: http-post driver had hardcoded timeout and did not
      support DNS lookups or TLS connections.
    - auth: Fix user iteration to work with userdb passwd with glibc v2.28.
    - auth: auth service can crash if auth-policy JSON response is invalid
      or returned too fast.
    - In some rare situations "ps" output could have shown a lot of "?"
      characters after Dovecot process titles.
    - When dovecot.index.pvt is empty, an unnecessary error is logged:
      Error: .../dovecot.index.pvt reset, view is now inconsistent
    - SMTP address encoder duplicated initial double quote character when
      the localpart of an address ended in '..'. For example
      "user+..@example.com" became ""user+.."@example.com in a
      sieve redirect.
    Pigeonhole 0.5.8
    - Sieve may leak resources in rare cases when a redirect, vacation or
      report action fails to send the message. This mainly applies when
      Sieve is executed in IMAP context; i.e., for the IMAPSIEVE or
      FILTER=SIEVE capabilities.
* Wed Aug 28 2019 Marcus Rueckert <mrueckert@suse.de>
  - update to 2.3.7.2
    * CVE-2019-11500: IMAP protocol parser does not properly handle
      NUL byte when scanning data in quoted strings, leading to out
      of bounds heap memory writes. Found by Nick Roessler and Rafi
      Rubin. (boo#1145559)
  - update pigeonhole to 0.5.7.2
    * CVE-2019-11500: ManageSieve protocol parser does not properly
      handle NUL byte when scanning data in quoted strings, leading
      to out of bounds heap memory writes. Found by Nick Roessler and
      Rafi Rubin. (boo#1145559)
  - refreshed patches to apply cleanly again:
    dovecot-2.3.0-better_ssl_defaults.patch
    dovecot-2.3.0-dont_use_etc_ssl_certs.patch
* Tue Jul 23 2019 Michael Ströder <michael@stroeder.com>
  - update to 2.3.7.1 and pigeonhole to 0.5.7.1
    Dovecot 2.3.7.1
    - Fix TCP_NODELAY errors being logged on non-Linux OSes
    - lmtp proxy: Fix assert-crash when client uses BODY=8BITMIME
    - Remove wrongly added checks in namespace prefix checking
    Pigeonhole 0.5.7.1
    - dsync: Sieve script syncing failed if mailbox attributes weren't enabled.
    Dovecot 2.3.7
    * fts-solr: Removed break-imap-search parameter
      + Added more events for the new statistics, see
      https://doc.dovecot.org/admin_manual/list_of_events/
      + mail-lua: Add IMAP metadata accessors, see
      https://doc.dovecot.org/admin_manual/lua/
      + Add event exporters that allow exporting raw events to log files and
      external systems, see
      https://doc.dovecot.org/configuration_manual/event_export/
      + SNIPPET is now PREVIEW and size has been increased to 200 characters.
      + Add body option to fts_enforced. This triggers building FTS index only
      on body search, and an error using FTS index fails the search rather
      than reads through all the mails.
    - Submission/LMTP: Fixed crash when domain argument is invalid in a
      second EHLO/LHLO command.
    - Copying/moving mails using Maildir format loses IMAP keywords in the
      destination if the mail also has no system flags.
    - mail_attachment_detection_options=add-flags-on-save caused email body
      to be unnecessarily opened when FETCHing mail headers that were
      already cached.
    - mail attachment detection keywords not saved with maildir.
    - dovecot.index.cache may have grown excessively large in some
      situations. This happened especially when using autoexpunging with
      lazy_expunge folders. Also with mdbox format in general the cache file
      wasn't recreated as often as it should have.
    - Autoexpunged mails weren't immediately deleted from the disk. Instead,
      the deletion from disk happened the next time the folder was opened.
      This could have caused unnecessary delays if the opening was done by
      an interactive IMAP session.
    - Dovecot's TCP connections sometimes add extra 40ms latency due to not
      enabling TCP_NODELAY. HTTP and SMTP/LMTP connections weren't
      affected, but everything else was. This delay wasn't always visible -
      only in some situations with some message/packet sizes.
    - imapc: Fix various crash conditions
    - Dovecot builds were not always reproducible.
    - login-proxy: With shutdown_clients=no after config reload the
      existing connections could no longer be listed or kicked with doveadm.
    - "doveadm proxy kick" with -f parameter caused a crash in some
      situations.
    - Auth policy can cause segmentation fault crash during auth process
      shutdown if all auth requests have not been finished.
    - Fix various minor bugs leading into incorrect behaviour in mailbox
      list index handling. These rarely caused noticeable problems.
    - LDAP auth: Iteration accesses freed memory, possibly crashing
      auth-worker
    - local_name { .. } filter in dovecot.conf does not correctly support
      multiple names and wildcards were matched incorrectly.
    - replicator: dsync assert-crashes if it can't connect to remote TCP
      server.
    - config: Memory leak in config process when ssl_dh setting wasn't
      set and there was no ssl-parameters.dat file.
      This caused config process to die once in a while
      with "out of memory".
* Mon May 20 2019 Peter Varkoly <varkoly@suse.com>
  - bsc#1134242 - upgrade from 42.3 to 15.1: dovecot shows Unknown
    protocol 'SSLv2'
    * remove !SSLv2 from existing ssl_protocols configuration
      during upgrade
* Tue Apr 30 2019 Marcus Rueckert <mrueckert@suse.de>
  - update pigeonhole to 0.5.6
    + sieve: Redirect loop prevention is sometimes ineffective.
      Improve existing loop detection by also recognizing the
      X-Sieve-Redirected-From header in incoming messages and
      dropping redirect actions when it points to the sending
      account. This header is already added by the redirect action,
      so this improvement only adds an additional use of this header.
    - sieve: Prevent execution of implicit keep upon temporary
      failure occurring at runtime.
* Tue Apr 30 2019 Marcus Rueckert <mrueckert@suse.de>
  - update to 2.3.6: (boo#1133624 boo#1133625)
    * CVE-2019-11494: Submission-login crashed with signal 11 due to
      null pointer access when authentication was aborted by
      disconnecting.
    * CVE-2019-11499: Submission-login crashed when authentication
      was started over TLS secured channel and invalid authentication
      message was sent.
    * auth: Support password grant with passdb oauth2.
    + Use system default CAs for outbound TLS connections.
    + Simplify array handling with new helper macros.
    + fts_solr: Enable configuring batch_size and soft_commit features.
    - lmtp/submission: Fixed various bugs in XCLIENT handling,
      including a hang when XCLIENT commands were sent infinitely to
      the remote server.
    - lmtp/submission: Forwarded multi-line replies were erroneously
      sent as two replies to the client.
    - lib-smtp: client: Message was not guaranteed to contain CRLF
      consistently when CHUNKING was used.
    - fts_solr: Plugin was no longer compatible with Solr 7.
    - Make it possible to disable certificate checking without
      setting ssl_client_ca_* settings.
    - pop3c: SSL support was broken.
    - mysql: Closing connection twice lead to crash on some systems.
    - auth: Multiple oauth2 passdbs crashed auth process on deinit.
    - HTTP client connection errors infrequently triggered a
      segmentation fault when the connection was idle and not used
      for a particular client instance.
  - drop https://github.com/dovecot/core/commit/3c5101ffd.patch
* Mon Apr 29 2019 Marcus Rueckert <mrueckert@suse.de>
  - backport https://github.com/dovecot/core/commit/3c5101ffd.patch
    [PATCH] driver-mysql: Avoid double-closing MySQL connection
* Thu Apr 18 2019 Marcus Rueckert <mrueckert@suse.de>
  - update to 2.3.5.2 (boo#1132501)
    * CVE-2019-10691: Trying to login with 8bit username containing
      invalid UTF8 input causes auth process to crash if auth policy
      is enabled. This could be used rather easily to cause a DoS.
      Similar crash also happens during mail delivery when using
      invalid UTF8 in From or Subject header when OX push
      notification driver is used.
* Thu Mar 28 2019 Marcus Rueckert <mrueckert@suse.de>
  - update to 2.3.5.1 (boo#1130116)
    * CVE-2019-7524: Missing input buffer size validation leads into
      arbitrary buffer overflow when reading fts or pop3 uidl header
      from Dovecot index. Exploiting this requires direct write
      access to the index files.
* Fri Mar 08 2019 Marcus Rueckert <mrueckert@suse.de>
  - update to 2.3.5
    + Lua push notification driver: mail keywords and flags are
      provided in MessageNew and MessageAppend events.
    + submission: Implement support for plugins.
    + auth: When auth_policy_log_only=yes, only log what the policy
      server response would do without actually doing it.
    + auth: Always log policy server decisions with auth_verbose=yes
    - v2.3.[34]: doveadm log errors: Output was missing user/session
    - lda: Debug log lines could have shown slightly corrupted
    - login proxy: Login processes may have crashed in various ways
      when login_proxy_max_disconnect_delay was set.
    - imap: Fix crash with Maildir+zlib if client disconnects during
      APPEND
    - lmtp proxy: Fix potential assert-crash
    - lmtp/submission: Fix crash when SMTP client transaction times
      out
    - submission: Split large XCLIENT commands to 512 bytes per
      command, so Postfix accepts them.
    - submission: Fix crash when client sends invalid BURL command
    - submission: relay backend: VRFY command: Avoid forwarding 500
      and 502 replies back to client.
    - lib-http: Fix potential assert-crash when DNS lookup fails
    - lib-fts: Fix search query generation when one language ignores
      a token (e.g. via stopwords).
  - update pigeonhole to 0.5.5
    + IMAPSieve: Add new plugin/imapsieve_expunge_discarded setting
      which causes messages discarded by an IMAPSieve script to be
      expunged immediately, rather than only being marked as
      "\Deleted" (which is still the default behavior).
    - IMAPSieve: Fix panic crash occurring when a COPY command copies
      messages from a virtual mailbox where the source messages
      originate from more than a single real mailbox.
    - imap4flags extension: Fix deleting all keywords. When the
      action resulted in all keywords being removed, no changes were
      actually applied.
    - variables extension: Fix truncation of UTF-8 variable content.
      The maximum size of Sieve variables was enforced by truncating
      the variable string content bluntly at the limit, but this does
      not consider UTF-8 code point boundaries. This resulted in
      broken UTF-8 strings. This problem also surfaced for variable
      modifiers, such as the ":encodeurl" modifier provided by the
      Sieve "enotify" extension. In that case, the resulting URI
      escaping could also be truncated inappropriately.
    - IMAPSieve, IMAP FILTER=SIEVE: Fix replacing a modified message.
      Sieve scripts running in IMAPSIEVE or IMAP FILTER=SIEVE context
      that modify the message, stored the message a second time,
      rather than replacing the originally stored unmodified message.
    - Fix segmentation fault occurring when both the
      sieve_extprograms plugin (for the Sieve interpreter) and the
      imap_filter_sieve plugin (for IMAP) are loaded at the same
      time. A symbol was defined by both plugins, causing a clash
      when both were loaded.
  - drop patches which were backports
    - 10048229...de42b54a.patch
    - 3c5101ffdd2a8115e03ed7180d53578765dea4c9.patch
* Tue Feb 05 2019 Marcus Rueckert <mrueckert@suse.de>
  - update to 2.3.4.1 (boo#1123022)
    * CVE-2019-3814: If imap/pop3/managesieve/submission client has
      trusted certificate with missing username field
      (ssl_cert_username_field), under some configurations Dovecot
      mistakenly trusts the username provided via authentication
      instead of failing.
    * ssl_cert_username_field setting was ignored with external
      SMTP AUTH, because none of the MTAs (Postfix, Exim) currently
      send the cert_username field. This may have allowed users with
      trusted certificate to specify any username in the
      authentication. This bug didn't affect Dovecot's Submission
      service.
* Thu Jan 17 2019 Arjen de Korte <suse+build@de-korte.org>
