postfix: update to 3.4.6
pkgsrc changes:
---------------
* change COMMENT to make pkglint happy (inspired by http://www.postfix.org/)
* update PLIST using make print-PLIST (missing @pkgdir)
upstream changes:
-----------------
20181125
Cleanup: dict_file_to_xxx() takes a list of file names
separated by CHARS_COMMA_SP. Shoe-horned into the existing
API, make it nicer when there is time. File: util/dict_file.c.
20181127
Cleanup: encapsulated clumsy 'read into VSTRING' code with
easier-to-use vstream_fread_buf() and vstream_fread_app()
primitives. Files: global/memcache_proto.c, global/record.c,
global/smtp_stream.c, global/smtp_stream.h, global/uxtext.c,
global/xtext.c, milter/milter8.c, util/dict_file.c,
util/hex_quote.c, util/netstring.c, util/vstream.c,
util/vstream.h. Verified with "make tests".
Cleanup: simplified the smtp_fread() API (introduced for
BDAT support), and changed the name to smtp_fread_buf().
Files: global/smtp_stream.c, smtpd/smtpd.c. Verified with
~megabyte BDAT commands.
Cleanup: simplified a tlsproxy-internal API. File:
tlsproxy/tlsproxy.c.
20181128
Initial support for key/certificate chain files that will
replace the proliferation of separate parameters for
RSA/DSA/ECC/etc. key and certificate files. Viktor
Dukhovni.
20181201
Cleanup: replaced the remaining unsafe VSTRING_AT_OFFSET()
calls with safe vstring_set_payload_size() calls, in code
that directly writes into VSTRING. Files: tls/tls_session.c,
tlsmgr/tlsmgr.c, util/casefold.c, util/vstring.c, util/vstring.h,
xsasl/xsasl_cyrus_client.c.
Cleanup: postscreen_command_time_limit did not need to be
a 'raw' parameter. This makes "postconf -x" behavior more
consistent. Files: global/mail_params.h, postscreen/postscreen.c.
Documentation: added text that the following parameter
values are not subject to Postfix parameter $name expansion:
default_rbl_reply, command_execution_directory, luser_relay,
smtpd_reject_footer. These have their own documented $name
substitution mechanism. File: proto/postconf.proto.
20181202
Bugfix: posttls-finger reported an error for UNIX-domain
connections, even if they did not fail. Found by Coverity.
File: posttls-finger/posttls-finger.c.
20181208
Documentation: add even more redundancy to the rate-delay
description. File: proto/postconf.proto.
20181210
Cleanup: code deduplication. File: util/dict_file.c.
20181226
Cleanup: code deduplication and better encapsulation with
PSC_DEL_CLIENT_STATE() and PSC_DEL_SERVER_STATE() macros.
Files: postscreen/postscreen.h, postscreen/postscreen_state.c.
Documentation: POSTSCREEN_README did not describe the
postscreen_post_queue_limit, and attributed the wrong reject
message to the postscreen_pre_queue_limit. Problem reported
by Michael Orlitzky. File: proto/POSTSCREEN_README.html.
(20181226-nonprod) Compatibility: removed support for OpenSSL
1.0.1 (not supported since December 31, 2016) and earlier
releases. This eliminated a large number of #ifdefs with
bitrot workarounds. Viktor Dukhovni. Files: global/mail_params.h,
posttls-finger/posttls-finger.c, tls/tls.h, tls/tls_certkey.c,
tls/tls_client.c, tls/tls_dane.c, tls/tls_dh.c, tls/tls_misc.c,
tls/tls_proxy_client_scan.c, tls/tls_rsa.c, tls/tls_server.c,
tls/tls_session.c.
(20181226-nonprod) Use the OpenSSL 1.0.2 and later API for
setting ECDHE curves. Viktor Dukhovni. Files: tls/tls.h,
tls/tls_client.c, tls/tls_dh.c.
(20181226-nonprod) Documentation update for TLS support.
Viktor Dukhovni. Files: mantools/postlink, proto/TLS_README.html,
proto/postconf.proto, src/sendmail/sendmail.c, src/smtpd/smtpd.c.
20181229
Explicit maps_file_find() and dict_file_lookup() methods
that decode base64 content. Decoding content is not built
into the dict->lookup() method, because that would complicate
the implementation of map nesting (inline, thash), map
composition (pipemap, unionmap), and map proxying. For
consistency, decoding base64 file content is also not built
into the maps_find() method. Files: util/dict.h.
util/dict_file.c, global/maps.[hc], postmap/postmap.c.
20190106
Documentation: documented the SRC_RHS_IS_FILE flag in
dict_open.c, and updated the -F description in the postmap
manpage. Files: util/dict_open.c, postmap/postmap.c.
(20190106-nonprod) Feature: support for files that combine
multiple (key, certificate, trust chain) instances in one
file, to avoid separate files for RSA, DSA, Elliptic Curve,
and so on. Viktor Dukhovni. Files: .indent.pro,
global/mail_params.h, posttls-finger/posttls-finger.c,
smtp/lmtp_params.c, smtp/smtp.c, smtp/smtp_params.c,

tls/tls_proxy_client_scan.c, tls/tls_proxy_server_print.c,
tls/tls_proxy_server_scan.c, tls/tls_server.c, tlsproxy/tlsproxy.c.
(20190106-nonprod) Create a second, no-key no-cert, SSL_CTX
for use with SNI. Viktor Dukhovni. Files: src/tls/tls.h,
src/tls/tls_client.c, src/tls/tls_misc.c, src/tls/tls_server.c.
(20190106-nonprod) Server-side SNI support. Viktor Dukhovni.
Files: src/global/mail_params.h, src/smtp/smtp.c,
src/smtpd/smtpd.c, src/tls/tls.h, src/tls/tls_certkey.c,
src/tls/tls_misc.c, src/tlsproxy/tlsproxy.c,
(20190106-nonprod) Configurable client-side SNI signal.
Viktor Dukhovni. Files: global/mail_params.h,
posttls-finger/posttls-finger.c, smtp/lmtp_params.c,
smtp/smtp.c, smtp/smtp.h, smtp/smtp_params.c, smtp/smtp_proto.c,
smtp/smtp_tls_policy.c, tls/tls.h, tls/tls_client.c,
tls/tls_proxy.h, tls/tls_proxy_client_print.c,
tls/tls_proxy_client_scan.c.
20190121
Logging: support for internal logging file, without using
syslog (it uses the new postlogd daemon instead). This
solves a usability problem for MacOS, may help getting
around systemd, and solves 99% of the problem for logging
to stdout in a container (hopefully we have 100% soon).
Enable by setting, for example, "maillog_file =
/var/log/postfix.log"). This works fine for daemons, and
with some limitations for non-daemon programs. See
RELEASE_NOTES for more details. Files: conf/master.cf,
conf/post-install, conf/postfix-files, conf/postfix-script,
mantools/postlink, proto/master, proto/postconf.proto,

Cleanup: cert/key/chain loading, plus unit tests to exercise
non-error and error cases. Viktor Dukhovni. Files: tls/*.pem,
tls*.pem.ref, tls/tls_certkey.c.
20190126
Safety: Postfix programs will log to either syslog or postlog
but not both; and postlogd forwards postlog logging to
syslog, when a configuration change removes the maillog_file
pathname, but some programs still use the old configuration.
Files: util/msg_syslog.[hc], util/msg_logger.c,
global/maillog_client.c, postlogd/postlogd.c,
Bugfix (introduced: Postfix 20110109, Postfix 2.10): watchdog
pipe file descriptor leak. This pipe provides one source
of liveness, data from this pipe is discarded, and therefore
this does not enable privilege escalation or DOS. File:
util/watchdog.c.
Feature: stdout logging support; requires "postfix start-fg"
and "maillog_file = /dev/stdout". Files: master/master.c,
conf/postfix-script.
20190127
Safety: when maillog_file is specified, 'postfix check' now
requires that the postlog service is enabled in master.cf.
Otherwise 'postfix start' etc. will log a fatal error. File:
conf/postfix-script.
Documentation: added policy_context example. File:
proto/SMTPD_POLICY_README.html.
20190128
Testing: run libtls tests under Valgrind. File tls/Makefile.in.
20190129
Safety: require that $maillog_file matches one of the
pathname prefixes specified in $maillog_file_prefixes. The
maillog file is created by root, and the prefixes limit the
damage from a single configuration error. Files:
global/mail_params.[hc], global/maillog_client.c.
20191201
Feature: "postfix logrotate" command with configurable
compression program and datestamp filename suffix. File:
conf/postfix-script.
20190202
Cleanup: log a warning when the client sends a malformed
SNI; log an info message when the client sends a valid SNI
that does not match the SNI lookup tables; update the
FORWARD_SECRECY_README logging examples. Viktor Dukhovni.
Files: proto/FORWARD_SECRECY_README.html, tls/tls.h,
tls/tls_client.c, tls/tls_misc.c.
20190208
Debugging: the master(8) daemon now logs a warning if a
master.cf entry is defined multiple times. File:
src/master/master_conf.c.
20190209
Debugging: tlsproxy(8) now logs more details about unexpected
configuration differences between the Postfix SMTP client
and the tlsproxy(8) daemon.
20190210
Documentation: Postfix 3.4.0 RELEASE NOTES.
Documentation: added BDAT_README.
Documentation: global TLS settings. Files: mantools/postlink,
smtp/smtp.c, tlsproxy/tlsproxy.c.
20190211
Cleanup: removed obsolete parameters: tls_dane_digest_agility,
tls_dane_trust_anchor_digest_enable; removed openssl_path
parameter from configuration difference checks in tlsproxy.
Files: global/mail_params.h, tls/tls_misc.c,
tls/tls_proxy_client_misc.c, tls/tls_proxy_client_print.c,
tls/tls_proxy_client_scan.c, tls/tls_proxy.h.
20190212
Cleanup: missing #ifdef USE_TLS. Files: smtp/smtp_session.c,
posttls-finger/posttls-finger.c.
20190217
Cleanup: when the master daemon runs with PID=1 (init mode),
reap orhpan processes from non-Postfix code running in the
same container, instead of terminating with a panic. File:
master/master_spawn.c.
20190218
Bugfix: tlsproxy did not enable DANE-style PKI because
libtls seems to have to accreted multiple init functions
instead of reusing the tls_client_init() and tls_client_start()
API. And some functions that do initialization don't even
have init in their name! Problem report by Andreas Schulze.
Viktor Dukhovni. Files: tls/tls_misc.c, tlsproxy/tlsproxy.c.
Workaround: Postfix libtls makes DANE-specific changes to
the shared SSL_CTX. To avoid false sharing, tlsproxy needs
to label the SSL_CTX cache with DANE bits until we can
remove the code that modifies SSL_CTX. File: tlsproxy/tlsproxy.c.
Cleanup: Postfix libtls changed the shared SSL_CTX to
override ciphers. instead of changing the SSL handle. To
avoid false sharing in tlsproxy, the changes are now made
to the SSL handle. Viktor Dukhovni. Files: tls/tls.h,
tls/tls_client.c, tls/tls_misc.c, tls/tls_server.c.
20190219
Bugfix: in the Postfix SMTP client, TLS wrappermode was not
tested in tlsproxy mode. It needed some setup for buffering
and timeouts. Problem report by Andreas Schulze. File:
smtp/smtp_proto.c.
20190304
Bugfix: a reversed test broke TLS configurations that specify
the same filename for a private key and certificate. Reported
by Mike Kazantsev. Fix by Viktor Dukhovni. Wietse fixed the
test. Files: tls/tls_certkey.c, tls/Makefile.in.
20190310
Bitrot: LINUX5s support, after some sanity checks with a
rawhide prerelease version. Files: makedefs, util/sys_defs.h.
Bugfix (introduced: 20181226): broken DANE trust anchor
file support, caused by left-over debris from the 20181226
TLS library overhaul. By intrigeri. File: tls/tls_dane.c.
Bugfix (introduced: Postfix-1.0.1): null pointer read, while
logging a warning after a corrupted bounce log file. File:
global/bounce_log.c.
Bugfix (introduced: Postfix-2.9.0): null pointer read, while
logging a warning after a postscreen_command_filter read
error. File: postscreen/postscreen_smtpd.c. global/bounce_log.c
20190312
Bugfix (introduced: Postfix 2.2): reject_multi_recipient_bounce
has been producing false rejects starting with the Postfix
2.2 smtpd_end_of_data_restrictons, and for the same reasons,
does the same with the Postfix 3.4 BDAT command. The latter
was reported by Andreas Schulze. File: smtpd/smtpd_check.c.
20190319
With message_size_limit=0 (which is NOT DOCUMENTED), BDAT
chunks were always rejected as too large. File: smtpd/smtpd.c
20190328
Bugfix (introduced: Postfix 3.0): LMTP connections over
UNIX-domain sockets were cached but not reused, due to a
cache lookup key mismatch. Therefore, idle cached connections
could exhaust LMTP server resources, resulting in two-second
pauses between email deliveries. This problem was investigated
by Juliana Rodrigueiro. File: smtp/smtp_connect.c.
20190331
Documentation: tlsext_padding is not a tls_ssl_options
feature. File: proto/postconf.proto.
20190401
Portability: added "#undef sun" to util/unix_dgram_connect.c.
20190403
Bugfix (introduced: Postfix 2.3): a censoring filter broke
multiline Milter responses for header/body events. Problem
report by Andreas Thienemann. Files: util/printable.c,
util/stringops.h, smtpd/smtpd.c
Bugfix (introduced: Postfix 3.3): "smtp_mx_address_limit =
0" no longer meant 'unlimited'. Problem report by Luc Pardon.
File: smtp/smtp_addr.c.
20190615
Documentation: updated the BUGS section in the smtp(8) manpage
about TLS connection reuse. File: smtp/smtp.c.
Workaround for implementations that hang Postfix while
shutting down a TLS session, until Postfix times out. With
"tls_fast_shutdown_enable = yes" (the default), Postfix no
longer waits for the TLS peer to respond to a TLS 'close'
request. This is recommended with TLSv1.0 and later. Files:
global/mail_params.h, tls/tls_session.c, and documentation.
20190621
Bugfix (introduced: Postfix 3.0): the code to reset Postfix
SMTP server command counts was not called after a HaProxy
handshake failure, causing stale numbers to be reported.
The command counts are now reset in the function that reports
the counts. File: smtpd/smtpd.c.
