Log message:
dovecot2: updated to 2.3.17.1

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.

Log message:
dovecot2: updated to 2.3.17

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.

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

mail: Remove SHA1 hashes for distfiles

Log message:
Update to 2.3.16. From the changelog:

* 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.

Log message:
mail/dovecot: update to 2.3.15

Security release.

v2.3.15 2021-06-21  Aki Tuomi <aki.tuomi@open-xchange.com>

* 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.

Log message:
mail/dovecot2: update to 2.3.14

From release announce:

	We have removed some components from the software, please
	review changelogs carefully prior upgrading.

V2.3.14 2021-03-04  Aki Tuomi <aki.tuomi@open-xchange.com>

* 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.
