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.

Add Exim MTA variants:
* exim
plain variant without any TLS library which hence comes
without TLS, DANE and DKIM.
* exim-openssl
linked against libopenssl
* exim-gnutls
linked against libgnutls
* exim-ldap
linked against libopenssl, libopenldap and libsasl2
Provide packages for lookup modules
* cdb
* dbmdb
* dnsdb
* json (depends on jansson)
* mysql (depends on libmariadb)
* passwd
* pgsql (depends on libpq)
* redis (depends on libhiredis)
* sqlite (depends on libsqlite3)
Note:
As gnutls requires libunbound which depends on libopenssl to provide
libgnutls-dane, disable DANE by default when building with gnutls.

The package Makefile contains a PKG_BUILD_DEPENDS=libiconv
line, which apart from being incorrect if libiconv-full is
specified in the build configuration, is also unnecessary,
since the package Makefile already includes nls.mk which
sets PKG_BUILD_DEPENDS appropriately.
