IPv6 has accidentally been disabled in all Exim builds since the
package was introduced in OpenWrt due to a faulty `sed` script. This
has now been fixed, so beware that IPv6 is now enabled when updating
from previous releases.
Upstream changes since version 4.96.2 (bottom up):
JH/s1 Refuse to accept a line "dot, LF" as end-of-DATA unless operating in
LF-only mode (as detected from the first header line). Previously we did
accept that in (normal) CRLF mode; this has been raised as a possible
attack scenario (under the name "smtp smuggling", CVE-2023-51766).
JH/01 The hosts_connection_nolog main option now also controls "no MAIL in
SMTP connection" log lines.
JH/02 Option default value updates:
- queue_fast_ramp (main) true (was false)
- remote_max_parallel (main) 4 (was 2)
JH/03 Cache static regex pattern compilations, for use by ACLs.
JH/04 Bug 2903: avoid exit on an attempt to rewrite a malformed address.
Make the rewrite never match and keep the logging. Trust the
admin to be using verify=header-syntax (to actually reject the message).
JH/05 Follow symlinks for placing a watch on TLS creds files. This means
(under Linux) we watch the dir containing the final file; previously
it would be the dir with the first symlink. We still do not monitor
the entire path.
JH/06 Check for bad chars in rDNS for sender_host_name. The OpenBSD (at least)
dn_expand() is happy to pass them through.
JH/07 OpenSSL Fix auto-reload of changed server OCSP proof. Previously, if
the file with the proof had an unchanged name, the new proof(s) were
loaded on top of the old ones (and nover used; the old ones were stapled).
JH/08 Bug 2915: Fix use-after-free for $regex<n> variables. Previously when
more than one message arrived in a single connection a reference from
the earlier message could be re-used. Often a sigsegv resulted.
These variables were introduced in Exim 4.87.
Debug help from Graeme Fowler.
JH/09 Fix ${filter } for conditions that modify $value. Previously the
modified version would be used in construction the result, and a memory
error would occur.
JH/10 GnuTLS: fix for (IOT?) clients offering no TLS extensions at all.
Find and fix by Jasen Betts.
JH/11 OpenSSL: fix for ancient clients needing TLS support for versions earlier
than TLSv1,2, Previously, more-recent versions of OpenSSL were permitting
the systemwide configuration to override the Exim config.
HS/01 Bug 2728: Introduce EDITME option "DMARC_API" to work around incompatible
API changes in libopendmarc.
JH/12 Bug 2930: Fix daemon startup. When started from any process apart from
pid 1, in the normal "background daemon" mode, having to drop process-
group leadership also lost track of needing to create listener sockets.
JH/13 Bug 2929: Fix using $recipients after ${run...}. A change made for 4.96
resulted in the variable appearing empty. Find and fix by Ruben Jenster.
JH/14 Bug 2933: Fix regex substring match variables for null matches. Since 4.96
a capture group which obtained no text (eg. "(abc)*" matching zero
occurrences) could cause a segfault if the corresponding $<n> was
expanded.
JH/15 Fix argument parsing for ${run } expansion. Previously, when an argument
included a close-brace character (eg. it itself used an expansion) an
error occurred.
JH/16 Move running the smtp connect ACL to before, for TLS-on-connect ports,
starting TLS. Previously it was after, meaning that attackers on such
ports had to be screened using the host_reject_connection main config
option. The new sequence aligns better with the STARTTLS behaviour, and
permits defences against crypto-processing load attacks, even though it
is strictly an incompatible change.
Also, avoid sending any SMTP fail response for either the connect ACL
or host_reject_connection, for TLS-on-connect ports.
JH/17 Permit the ACL "encrypted" condition to be used in a HELO/EHLO ACL,
Previously this was not permitted, but it makes reasonable sense.
While there, restore a restriction on using it from a connect ACL; given
the change JH/16 it could only return false (and before 4.91 was not
permitted).
JH/18 Fix a fencepost error in logging. Previously (since 4.92) when a log line
was exactly sized compared to the log buffer, a crash occurred with the
misleading message "bad memory reference; pool not found".
Found and traced by Jasen Betts.
JH/19 Bug 2911: Fix a recursion in DNS lookups. Previously, if the main option
dns_again_means_nonexist included an element causing a DNS lookup which
itself returned DNS_AGAIN, unbounded recursion occurred. Possible results
included (though probably not limited to) a process crash from stack
memory limit, or from excessive open files. Replace this with a paniclog
whine (as this is likely a configuration error), and returning
DNS_NOMATCH.
JH/20 Bug 2954: (OpenSSL) Fix setting of explicit EC curve/group. Previously
this always failed, probably leading to the usual downgrade to in-clear
connections.
JH/21 Fix TLSA lookups. Previously dns_again_means_nonexist would affect
SERVFAIL results, which breaks the downgrade resistance of DANE. Change
to not checking that list for these lookups.
JH/22 Bug 2434: Add connection-elapsed "D=" element to more connection
closure log lines.
JH/23 Fix crash in string expansions. Previously, if an empty variable was
immediately followed by an expansion operator, a null-indirection read
was done, killing the process.
JH/24 Bug 2997: When built with EXPERIMENTAL_DSN_INFO, bounce messages can
include an SMTP response string which is longer than that supported
by the delivering transport. Alleviate by wrapping such lines before
column 80.
JH/25 Bug 2827: Restrict size of References: header in bounce messages to 998
chars (RFC limit). Previously a limit of 12 items was made, which with
a not-impossible References: in the message being bounced could still
be over-large and get stopped in the transport.
JH/26 For a ${readsocket } in TLS mode, send a TLS Close Alert before the TCP
close. Previously a bare socket close was done.
JH/27 Fix ${srs_encode ..}. Previously it would give a bad result for one day
every 1024 days.
JH/28 Bug 2996: Fix a crash in the smtp transport. When finding that the
message being considered for delivery was already being handled by
another process, and having an SMTP connection already open, the function
to close it tried to use an uninitialized variable. This would afftect
high-volume sites more, especially when running mailing-list-style loads.
Pollution of logs was the major effect, as the other process delivered
the message. Found and partly investigated by Graeme Fowler.
JH/29 Change format of the internal ID used for message identification. The old
version only supported 31 bits for a PID element; the new 64 (on systems
which can use Base-62 encoding, which is all currently supported ones
but not Darwin (MacOS) or Cygwin, which have case-insensitive filesystems
and must use Base-36). The new ID is 23 characters rather than 16, and is
visible in various places - notably logs, message headers, and spool file
names. Various of the ancillary utilities also have to know the format.
As well as the expanded PID portion, the sub-second part of the time
recorded in the ID is expanded to support finer precision. Theoretically
this permits a receive rate from a single comms channel of better than the
previous 2000/sec.
The major timestamp part of the ID is not changed; at 6 characters it is
usable until about year 3700.
Updating from previously releases is fully supported: old-format spool
files are still usable, and the utilities support both formats. New
message will use the new format. The one hints-DB file type which uses
message-IDs (the transport wait- DB) will be discarded if an old-format ID
is seen; new ones will be built with only new-format IDs.
Optionally, a utility can be used to convert spool files from old to new,
but this is only an efficiency measure not a requirement for operation
Downgrading from new to old requires running a provided utility, having
first stopped all operations. This will convert any spool files from new
back to old (losing time-precision and PID information) and remove any
wait- hints databases.
JH/30 Bug 3006: Fix handling of JSON strings having embedded commas. Previously
we treated them as item separators when parsing for a list item, but they
need to be protected by the doublequotes. While there, add handling for
backslashes.
JH/31 Bug 2998: Fix ${utf8clean:...} to disallow UTF-16 surrogate codepoints.
Found and fixed by Jasen Betts. No testcase for this as my usual text
editor insists on emitting only valid UTF-8.
JH/32 Fix "tls_dhparam = none" under GnuTLS. At least with 3.7.9 this gave
a null-indirection SIGSEGV for the receive process.
JH/33 Fix free for live variable $value created by a ${run ...} expansion during
-bh use. Internal checking would spot this and take a panic.
JH/34 Bug 3013: Fix use of $recipients within arguments for ${run...}.
In 4.96 this would expand to empty.
JH/35 Bug 3014: GnuTLS: fix expiry date for an auto-generated server
certificate. Find and fix by Andreas Metzler.
JH/36 Add ARC info to DMARC hostory records.
JH/37 Bug 3016: Avoid sending DSN when message was accepted under fakereject
or fakedefer. Previously the sender could discover that the message
had in fact been accepted.
JH/38 Taint-track intermediate values from the peer in multi-stage authentation
sequences. Previously the input was not noted as being tainted; notably
this resulted in behaviour of LOGIN vs. PLAIN being inconsistent under
bad coding of authenticators.
JH/39 Bug 3023: Fix crash induced by some combinations of zero-length strings
and ${tr...}. Found and diagnosed by Heiko Schlichting.
JH/40 Bug 2999: Fix a possible OOB write in the external authenticator, which
CVE-2023-42115

* No changes - release done to keep version numbers synced.
Signed-off-by: Daniel Golle <daniel@makrotopia.org>
v2.3.20 2022-12-22 Aki Tuomi <aki.tuomi@open-xchange.com>
+ 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
https://doc.dovecot.org/admin_manual/lua/#dovecot.http.client
+ 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
backends.
- 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
introspections.
- 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
histogram group_by configurations. Prometheus rejected these labels.
v2.3.19.1 2022-06-14 Aki Tuomi <aki.tuomi@open-xchange.com>
- 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)
v2.3.19 2022-05-10 Aki Tuomi <aki.tuomi@open-xchange.com>
+ 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)

Exim version 4.96
-----------------
JH/01 Move the wait-for-next-tick (needed for unique message IDs) from
after reception to before a subsequent reception. This should
mean slightly faster delivery, and also confirmation of reception
to senders.
JH/02 Move from using the pcre library to pcre2. The former is no longer
being developed or supported (by the original developer).
JH/03 Constification work in the filters module required a major version
bump for the local-scan API. Specifically, the "headers_charset"
global which is visible via the API is now const and may therefore
not be modified by local-scan code.
JH/04 Fix ClamAV TCP use under FreeBSD. Previously the OS-specific shim for
sendfile() didi not account for the way the ClamAV driver code called it.
JH/05 Bug 2819: speed up command-line messages being read in. Previously a
time check was being done for every character; replace that with one
per buffer.
JH/06 Bug 2815: Fix ALPN sent by server under OpenSSL. Previously the string
sent was prefixed with a length byte.
JH/07 Change the SMTP feature name for pipelining connect to be compliant with
RFC 5321. Previously Dovecot (at least) would log errors during
submission.
JH/08 Remove stripping of the binaries from the FreeBSD build. This was added
in 4.61 without a reason logged. Binaries will be bigger, which might
matter on diskspace-constrained systems, but debug is easier.
JH/09 Fix macro-definition during "-be" expansion testing. The move to
write-protected store for macros had not accounted for these runtime
additions; fix by removing this protection for "-be" mode.
JH/10 Convert all uses of select() to poll(). FreeBSD 12.2 was found to be
handing out large-numbered file descriptors, violating the usual Unix
assumption (and required by Posix) that the lowest possible number will be
allocated by the kernel when a new one is needed. In the daemon, and any
child procesees, values higher than 1024 (being bigger than FD_SETSIZE)
are not useable for FD_SET() [and hence select()] and overwrite the stack.
Assorted crashes happen.
JH/11 Fix use of $sender_host_name in daemon process. When used in certain
main-section options or in a connect ACL, the value from the first ever
connection was never replaced for subsequent connections. Found by
Wakko Warner.
JH/12 Bug 2838: Fix for i32lp64 hard-align platforms. Found for SPARC Linux,
though only once PCRE2 was introduced: the memory accounting used under
debug offset allocations by an int, giving a hard trap in early startup.
Change to using a size_t. Debug and fix by John Paul Adrian Glaubitz.
JH/13 Bug 2845: Fix handling of tls_require_ciphers for OpenSSL when a value
with underbars is given. The write-protection of configuration introduced
in 4.95 trapped when normalisation was applied to an option not needing
expansion action.
JH/14 Bug 1895: TLS: Deprecate RFC 5114 Diffie-Hellman parameters.
JH/15 Fix a resource leak in *BSD. An off-by-one error resulted in the daemon
failing to close the certificates directory, every hour or any time it
was touched.
JH/16 Debugging initiated by an ACL control now continues through into routing
and transport processes. Previously debugging stopped any time Exim
re-execs, or for processing a queued message.
JH/17 The "expand" debug selector now gives more detail, specifically on the
result of expansion operators and items.
JH/18 Bug 2751: Fix include_directory in redirect routers. Previously a
bad comparison between the option value and the name of the file to
be included was done, and a mismatch was wrongly identified.
4.88 to 4.95 are affected.
JH/19 Support for Berkeley DB versions 1 and 2 is withdrawn.
JH/20 When built with NDBM for hints DB's check for nonexistence of a name
supplied as the db file-pair basename. Previously, if a directory
path was given, for example via the autoreply "once" option, the DB
file.pag and file.dir files would be created in that directory's
parent.
JH/21 Remove the "allow_insecure_tainted_data" main config option and the
"taint" log_selector. These were previously deprecated.
JH/22 Fix static address-list lookups to properly return the matched item.
Previously only the domain part was returned.
JH/23 Bug 2864: FreeBSD: fix transport hang after 4xx/5xx response. Previously
the call into OpenSSL to send a TLS Close was being repeated; this
resulted in the library waiting for the peer's Close. If that was never
sent we waited forever. Fix by tracking send calls.
JH/24 The ${run} expansion item now expands its command string elements after
splitting. Previously it was before; the new ordering makes handling
zero-length arguments simpler. The old ordering can be obtained by
appending a new option "preexpand", after a comma, to the "run".
JH/25 Taint-check exec arguments for transport-initiated external processes.
Previously, tainted values could be used. This affects "pipe", "lmtp" and
"queryprogram" transport, transport-filter, and ETRN commands.
The ${run} expansion is also affected: in "preexpand" mode no part of
the command line may be tainted, in default mode the executable name
may not be tainted.
JH/26 Fix CHUNKING on a continued-transport. Previously the usabliility of
the the facility was not passed across execs, and only the first message
passed over a connection could use BDAT; any further ones using DATA.
JH/27 Support the PIPECONNECT facility in the smtp transport when the helo_data
uses $sending_ip_address and an interface is specified.
Previously any use of the local address in the EHLO name disabled
PIPECONNECT, the common case being to use the rDNS of it.
JH/28 OpenSSL: fix transport-required OCSP stapling verification under session
resumption. Previously verify failed because no certificate status is
passed on the wire for the restarted session. Fix by using the recorded
ocsp status of the stored session for the new connection.
JH/29 TLS resumption: the key for session lookup in the client now includes
more info that a server could potentially use in configuring a TLS
session, avoiding oferring mismatching sessions to such a server.
Previously only the server IP was used.
JH/30 Fix string_copyn() for limit greater than actual string length.
Previously the copied amount was the limit, which could result in a
overlapping memcpy for newly allocated destination soon after a
source string shorter than the limit. Found/investigated by KM.
JH/31 Bug 2886: GnuTLS: Do not free the cached creds on transport connection
close; it may be needed for a subsequent connection. This caused a
SEGV on primary-MX defer. Found/investigated by Gedalya & Andreas.
JH/32 Fix CHUNKING for a second message on a connection when the first was
rejected. Previously we did not reset the chunking-offered state, and
erroneously rejected the BDAT command. Investigation help from
Jesse Hathaway.
JH/33 Fis ${srs_encode ...} to handle an empty sender address, now returning
an empty address. Previously the expansion returned an error.
HS/01 Bug 2855: Handle a v4mapped sender address given us by a frontending
proxy. Previously these were misparsed, leading to paniclog entries.
Also contains commit 51be321b27 "Fix PAM auth. Bug 2813" addressing
CVE-2022-37451.

macos build fails due to two reasons:
1. using build host ar and ranlib tools
2. using uname -r to get kernel version
First issue is fixed by specifying ar and ranlib from toolchain
Second issue is fixed by specifying kernel release major version=5
Using 'uname -r' from build host for cross-compiling is not a good
idea even for Linux build host

This adds a patch from Open embedded to fix compilation with glibc 2.34.
This patch was taken from here:
https://github.com/openembedded/meta-openembedded/blob/master/meta-networking/recipes-daemons/postfix/files/0007-correct-signature-of-closefrom-API.patch
It fixes the following build problem:
/builder/shared-workdir/build/sdk/staging_dir/toolchain-arc_arc700_gcc-11.2.0_glibc/include/unistd.h:366:13: error: conflicting types for 'closefrom'; have 'void(int)'

Postfix's options should not be visible in the config when Postfix
is not enabled.
Secondly, place the config option menu behind the Postfix option rather
than underneath.
