dovecot2: updated to 2.3.20


+ Add dsync_features=no-header-hashes. When this setting is enabled and
  one dsync side doesn't support mail GUIDs (i.e. imapc), there is no
  fallback to using header hashes. Instead, dsync assumes that all mails
  with identical IMAP UIDs contains the same mail contents. This can
  significantly improve dsync performance with some IMAP servers that
  don't support caching Date/Message-ID headers.
+ lua: HTTP client has more settings now, see
+ replicator: "doveadm replicator status" command now outputs when the
  next sync is expected for the user.
- LAYOUT=index: duplicate GUIDs were not cleaned out. Also the list
  recovery was not optimal.
- auth: Assert crash would occur when iterating multiple userdb
- director: Logging into director using master user with
  auth_master_user_separator character redirected user to a wrong
  backend, unless master_user_separator setting was also set to the same
  value. Merged these into auth_master_user_separator.
- dsync: Couldn't always fix folder GUID conflicts automatically with
  Maildir format. This resulted in replication repeatedly failing
  with "Remote lost mailbox GUID".
- dsync: Failed to migrate INBOX when using namespace prefix=INBOX/,
  resulting in "Remote lost mailbox GUID" errors.
- dsync: INBOX was created too early with namespace prefix=INBOX/,
  resulting a GUID conflict. This may have been resolved automatically,
  but not always.
- dsync: v2.3.18 regression: Wrong imapc password with dsync caused
  Panic: file lib-event.c: line 506 (event_pop_global):
  assertion failed: (event == current_global_event)
- imapc: Requesting STATUS for a mailbox with imapc and INDEXPVT
  configured did not return correct (private) unseen counts.
- lib-dict: Process would crash when committing data to redis without
  dict proxy.
- lib-mail: Corrupted cached BODYSTRUCTURE caused panic during FETCH.
  Fixes: Panic: file message-part-data.c: line 579 (message_part_is_attachment):
  assertion failed: (data != NULL). v2.3.13 regression.
- lib-storage: mail_attribute_dict with dict-sql failed when it tried to
  lookup empty dict keys.
- lib: ioloop-kqueue was missing include breaking some BSD builds.
- lua-http: Dovecot Lua HTTP client could not resolve DNS names in mail
  processes, because it expected "dns-client" socket to exist in the
  current directory.
- oauth2: Using %{oauth2:name} variables could cause useless
- pop3: Sending POP3 command with ':' character caused an assert-crash.
  v2.3.18 regression.
- replicator: Replication queue had various issues, potentially causing
  replication requests to become stuck.
- stats: Invalid Prometheus label names were created with specific

v0.5.20 of Pigeonhole
* No changes - release done to keep version numbers synced.

dovecot2: updated to 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
+ 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
+ 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
- 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)

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
+ 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
+ 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 \ 
  assertion failed: (ctx->nested_parts_count == 0 || \ 
- 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
- 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
- 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.
