PP
22 (Only plugin which currently uses this is kerberos4, which nobody should
23 be using, but we should make it available and other future plugins might
24 conceivably use it, even though it would break NAT; stuff *should* be
25 using channel bindings instead).

c80c5570
PP
92PP/14 TLS fixes for OpenSSL: support TLS 1.1 & 1.2; new "openssl_options"
93 values; set SSL_MODE_AUTO_RETRY so that OpenSSL will retry a read
94 or write after TLS renegotiation, which otherwise led to messages
95 "Got SSL error 2".

114PP/17 OpenSSL: new expansion var $tls_sni, which if used in tls_certificate
115 lets Exim select keys and certificates based upon TLS SNI from client.

PP
122PP/19 DNS resolver init changes for NetBSD compatibility. (Risk of breakage
123 on less well tested platforms). Obviates NetBSD pkgsrc patch-ac.
124 Not seeing resolver debug output on NetBSD, but suspect this is a
125 resolver implementation change.
126
c6e95d22
PP
127PP/20 Revert part of NM/04, it broke log_path containing %D expansions.
128 Left warnings. Added "eximon gdb" invocation mode.

138 Bugzilla 1246, report and most of solution from Tomasz Kusy.
139
9e45c72b 140JH/03 ${eval } now uses 64-bit and supports a "g" suffix (like to "k" and "m").
97d17305
JH
141 This may cause build issues on older platforms.
142
17c76198
PP
143PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
144 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
145 gnutls_require_mac & gnutls_require_protocols (no longer supported).
146 Added SNI support via GnuTLS too.
af3498d6 147 Made ${randint:..} supplier available, if using not-too-old GnuTLS.
17c76198 148

158 read-only, out of scope).
159 Patch from Wolfgang Breyha, report from Stuart Northfield.
160
08488c86
PP
161PP/29 Fix three issues highlighted by clang analyser static analysis.
162 Only crash-plausible issue would require the Cambridge-specific
163 iplookup router and a misconfiguration.
164 Report from Marcin Mirosław.
165
6475bd82
PP
166PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
167
81f91683
PP
168PP/31 %D in printf continues to cause issues (-Wformat=security), so for
169 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
170 As part of this, removing so much warning spew let me fix some minor
171 real issues in debug logging.
172
5779e6aa
PP
173PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
174 assignment on my part. Fixed.
175
3375e053
PP
176PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
177 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
178 Janne Snabb (who went above and beyond: thank you).
179
180PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
181 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
182 relatively easy to get wrong. Should also expose TLS library linkage
183 problems.
3375e053 184
9d26b8c0
PP
185PP/35 Pull in <features.h> on Linux, for some portability edge-cases of
186 64-bit ${eval} (JH/03).
187
57eb9e91 188PP/36 Define _GNU_SOURCE in exim.h; it's needed for some releases of
b87a6e0e
PP
189 GNU libc to support some of the 64-bit stuff, should not lead to
190 conflicts. Defined before os.h is pulled in, so if a given platform
191 needs to override this, it can.
192
16880d1a
PP
193PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
194 protection layer was required, which is not implemented.
195 Bugzilla 1254, patch from Wolfgang Breyha.
196
a799883d
PP
197PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
198 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
199 tls_dhparam take prime identifiers. Also unbreak combination of
200 OpenSSL+DH_params+TLSSNI.
201

217 when unlink() failed. See also change 4.74-TF/03.
218
921b12ca
TF
219TF/03 Make the exiwhat support code safe for signals. Previously Exim might
220 lock up or crash if it happened to be inside a call to libc when it
221 got a SIGUSR1 from exiwhat.
222
223 The SIGUSR1 handler appends the current process status to the process
224 log which is later printed by exiwhat. It used to use the general
225 purpose logging code to do this, but several functions it calls are
226 not safe for signals.
227
228 The new output code in the SIGUSR1 handler is specific to the process
229 log, and simple enough that it's easy to inspect for signal safety.
230 Removing some special cases also simplifies the general logging code.
231 Removing the spurious timestamps from the process log simplifies
232 exiwhat.
233
c99ce5c9
TF
234TF/04 Improved ratelimit ACL condition.
235
236 The /noupdate option has been deprecated in favour of /readonly which
237 has clearer semantics. The /leaky, /strict, and /readonly update modes
238 are mutually exclusive. The update mode is no longer included in the
239 database key; it just determines when the database is updated. (This
240 means that when you upgrde Exim will forget old rate measurements.)
241
242 Exim now checks that the per_* options are used with an update mode that
243 makes sense for the current ACL. For example, when Exim is processing a
244 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
245 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
246 must specify per_mail/readonly. If you omit the update mode it defaults to
247 /leaky where that makes sense (as before) or /readonly where required.
248
249 The /noupdate option is now undocumented but still supported for
250 backwards compatibility. It is equivalent to /readonly except that in
251 ACLs where /readonly is required you may specify /leaky/noupdate or
252 /strict/noupdate which are treated the same as /readonly.
253
254 A useful new feature is the /count= option. This is a generalization
255 of the per_byte option, so that you can measure the throughput of other
256 aggregate values. For example, the per_byte option is now equivalent
257 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
258
259 The per_rcpt option has been generalized using the /count= mechanism
260 (though it's more complicated than the per_byte equivalence). When it is
261 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
262 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
263 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
264 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
265 Note that using per_rcpt with a non-readonly update mode in more than
266 one ACL will cause the recipients to be double-counted. (The per_mail
267 and per_byte options don't have this problem.)
268
269 The handling of very low rates has changed slightly. If the computed rate
270 is less than the event's count (usually one) then this event is the first
271 after a long gap. In this case the rate is set to the same as this event's
272 count, so that the first message of a spam run is counted properly.
273
274 The major new feature is a mechanism for counting the rate of unique
275 events. The new per_addr option counts the number of different
276 recipients that someone has sent messages to in the last time period. It
277 behaves like per_rcpt if all the recipient addresses are different, but
278 duplicate recipient addresses do not increase the measured rate. Like
279 the /count= option this is a general mechanism, so the per_addr option
280 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
281 example, measure the rate that a client uses different sender addresses
282 with the options per_mail/unique=$sender_address. There are further
283 details in the main documentation.

833 Note to Michael Haardt: I had to rename some vars in sieve.c. They
834 were called 'true' and it seems that C99 defines that as a reserved

836 not include C99-style headers which use bools without triggering

856

PH
857PH/02 When an IPv6 address is converted to a string for single-key lookup
858 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
859 dots are used instead of colons so that keys in lsearch files need not
860 contain colons. This was done some time before quoting was made available
861 in lsearch files. However, iplsearch files do require colons in IPv6 keys
862 (notated using the quote facility) so as to distinguish them from IPv4
863 keys. This meant that lookups for IP addresses in host lists did not work
864 for iplsearch lookups.
865
866 This has been fixed by arranging for IPv6 addresses to be expressed with
867 colons if the lookup type is iplsearch. This is not incompatible, because
868 previously such lookups could never work.
869
870 The situation is now rather anomolous, since one *can* have colons in
871 ordinary lsearch keys. However, making the change in all cases is
872 incompatible and would probably break a number of configurations.

877MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
878 conversion specification without a maximum field width, thereby enabling
879 a rogue spamd server to cause a buffer overflow. While nobody in their
880 right mind would setup Exim to query an untrusted spamd server, an
881 attacker that gains access to a server running spamd could potentially
882 exploit this vulnerability to run arbitrary code as the Exim user.

MH
887MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
888 a directory entry by the name of the lookup key. Previously, if a
889 symlink pointed to a non-existing file or a file in a directory that
890 Exim lacked permissions to read, a lookup for a key matching that
891 symlink would fail. Now it is enough that a matching directory entry
892 exists, symlink or not. (Bugzilla 503.)

1075PH/29 SMTP synchronization checks are implemented when a command is read -
1076 there is a check that no more input is waiting when there shouldn't be
1077 any. However, for some commands, a delay in an ACL can mean that it is
1078 some time before the response is written. In this time, more input might
1079 arrive, invalidly. So now there are extra checks after an ACL has run for
1080 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1081 pipelining has not been advertised.

1096 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1097 was a macro that became an assignment, so it seemed to work. This has

PH
1155 the response to the final '.' that terminates a message, but only in the
1156 case where the client has not sent further data following the '.'
1157 (unfortunately, this is allowed). However, in many cases there won't be
1158 any further data because there won't be any more messages to send. A call
1159 to select() can be used: if it shows that the input is "ready", there is
1160 either input waiting, or the socket has been closed. An attempt to read
1161 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1162 would have sent an OK response which the client would never have see.

1172
1173PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1174 fixed by 4.65/MH/01 (is this a record?) are fixed:
1175
1176 (i) An empty string was always treated as zero by the numeric comparison
1177 operators. This behaviour has been restored.
1178
1179 (ii) It is documented that the numeric comparison operators always treat
1180 their arguments as decimal numbers. This was broken in that numbers
1181 starting with 0 were being interpreted as octal.
1182
1183 While fixing these problems I realized that there was another issue that
1184 hadn't been noticed. Values of message_size_limit (both the global option
1185 and the transport option) were treated as octal if they started with 0.
1186 The documentation was vague. These values are now always treated as
1187 decimal, and I will make that clear in the documentation.

1201PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1202 child addresses, Exim now panics and dies. Previously, because the count
1203 is held in a short int, deliveries were likely to be lost. As such a
1204 large number of recipients for a single message is ridiculous
1205 (performance will be very, very poor), I have chosen to impose a limit
1206 rather than extend the field.

1212TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1213 leftover -K file (the existence of which was triggered by #402).
1214 While we were at it, introduced process PID as part of the -K
1215 filename. This should rule out race conditions when creating
1216 these files.

1218TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1219 processing considerably. Previous code took too long for large mails,
1220 triggering a timeout which in turn triggers #401.
1221
1222TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1223 in the DK code in transports.c. sendfile() is not really portable,
1224 hence the _LINUX specificness.

1226TF/01 In the add_headers option to the mail command in an Exim filter,

1228 header after the first one which had an odd number of characters
1229 in the field name.

2b1c6e3a
PH
1231PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1232 callout verification, Exim cached a "reject" for the entire domain. This
1233 is correct for most verifications, but it is not correct for a recipient
1234 verification with use_sender or use_postmaster set, because in that case
1235 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1236 case of MAIL FROM:<> rejection from other early rejections (e.g.
1237 rejection of HELO). When verifying a recipient using a non-null MAIL
1238 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1239 Whatever the result of the callout, the value of the domain cache is
1240 left unchanged (for any other kind of callout, getting as far as trying
1241 RCPT means that the domain itself is ok).

1275PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1276 hostname. This is wrong, because it relates to the incoming message (and
1277 probably the interface on which it is arriving) and not to the outgoing
1278 callout (which could be using a different interface). This has been
1279 changed to use the value of the helo_data option from the smtp transport
1280 instead - this is what is used when a message is actually being sent. If
1281 there is no remote transport (possible with a router that sets up host
1282 addresses), $smtp_active_hostname is used.

14aa5a05 1284PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1285 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1286 (a) The code assumed that strncpy() returns a negative number on buffer
1287 overflow, which isn't the case. Replaced with Exim's string_format()
1288 function.
1289 (b) There were several signed/unsigned issues. I just did the minimum
1290 hacking in of casts. There is scope for a larger refactoring.
1291 (c) The code used strcasecmp() which is not a standard C function.
1292 Replaced with Exim's strcmpic() function.
1293 (d) The code set only $1; it now sets $auth1 as well.
1294 (e) A simple test gave the error "authentication client didn't specify
1295 service in request". It would seem that Dovecot has changed its
1296 interface. Fortunately there's a specification; I followed it and
1297 changed what the client sends and it appears to be working now.

1302PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1303 address A is aliased to B and C, where B exists and C does not. Without
1304 -v the output is "A verified" because verification stops after a
1305 successful redirection if more than one address is generated. However,
1306 with -v the child addresses are also verified. Exim was outputting "A
1307 failed to verify" and then showing the successful verification for C,
1308 with its parentage. It now outputs "B failed to verify", showing B's
1309 parentage before showing the successful verification of C.

1312 look up a TXT record in a specific list after matching in a combined

1314
322050c2
PH
1315PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1316 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1317 they consult the DNS. I had assumed they would set it the way they
1318 wanted; and indeed my experiments on Linux seem to show that in some
1319 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1320 To be on the safe side, however, I have now made the interface to
1321 host_find_byname() similar to host_find_bydns(), with an argument
1322 containing the DNS resolver options. The host_find_byname() function now
1323 sets these options at its start, just as host_find_bydns() does. The smtp
1324 transport options dns_qualify_single and dns_search_parents are passed to
1325 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1326 of host_find_byname() use the default settings of RES_DEFNAMES
1327 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1329PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1330 spool_read_header() do less string testing, by means of a preliminary
1331 switch on the second character of optional "-foo" lines. (This is
1332 overdue, caused by the large number of possibilities that now exist.
1333 Originally there were few.) While I was there, I also converted the
1334 str(n)cmp tests so they don't re-test the leading "-" and the first
1335 character, in the hope this might squeeze out yet more improvement.
1336

PH
1337PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1338 flag allowing group syntax was set by the header_syntax check but not
1339 turned off, possible causing trouble later; (2) The flag was not being
1340 set at all for the header_verify test, causing "group"-style headers to
1341 be rejected. I have now set it in this case, and also caused header_
1342 verify to ignore an empty address taken from a group. While doing this, I
1343 came across some other cases where the code for allowing group syntax
1344 while scanning a header line wasn't quite right (mostly, not resetting
1345 the flag correctly in the right place). These bugs could have caused
1346 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1348PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1349 with the "reply" argument non-NULL. The code, however (which originally
1350 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1351 but it didn't always do it. This confused somebody who was copying the
1352 code for some other use. I have removed all the tests.

411ef850
PH
1354PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1355 feature that was used to support insecure browsers during the U.S. crypto
1356 embargo. It requires special client support, and Exim is probably the
1357 only MTA that supported it -- and would never use it because real RSA is
1358 always available. This code has been removed, because it had the bad
1359 effect of slowing Exim down by computing (never used) parameters for the
1360 RSA_EXPORT functionality.
1361
7befa435
PH
1362PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1363 authenticator to fail if there's a tab character in the incoming data
1364 (there should never be unless someone is messing about, as it's supposed
1365 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1366 if the connection is using TLS or if the remote IP is the same as the
1367 local IP, and the "valid-client-cert option" if a client certificate has
1368 been verified.

1399
1400PH/30 Exim was sometimes attempting to deliver messages that had suffered
1401 address errors (4xx response to RCPT) over the same connection as other
1402 messages routed to the same hosts. Such deliveries are always "forced",
1403 so retry times are not inspected. This resulted in far too many retries
1404 for the affected addresses. The effect occurred only when there were more
1405 hosts than the hosts_max_try setting in the smtp transport when it had
1406 the 4xx errors. Those hosts that it had tried were not added to the list
1407 of hosts for which the message was waiting, so if all were tried, there
1408 was no problem. Two fixes have been applied:
1409
1410 (i) If there are any address or message errors in an SMTP delivery, none
1411 of the hosts (tried or untried) are now added to the list of hosts
1412 for which the message is waiting, so the message should not be a
1413 candidate for sending over the same connection that was used for a
1414 successful delivery of some other message. This seems entirely
1415 reasonable: after all the message is NOT "waiting for some host".
1416 This is so "obvious" that I'm not sure why it wasn't done
1417 previously. Hope I haven't missed anything, but it can't do any
1418 harm, as the worst effect is to miss an optimization.
1419
1420 (ii) If, despite (i), such a delivery is accidentally attempted, the
1421 routing retry time is respected, so at least it doesn't keep
1422 hammering the server.

PH
1437PH/35 The error "getsockname() failed: connection reset by peer" was being
1438 written to the panic log as well as the main log, but it isn't really
1439 panic-worthy as it just means the connection died rather early on. I have
1440 removed the panic log writing for the ECONNRESET error when getsockname()
1441 fails.
1442
48c7f9e2
PH
1443PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1444 runs only) independently of the message's sender address. This meant
1445 that, if the 4xx error was in fact related to the sender, a different
1446 message to the same recipient with a different sender could confuse
1447 things. In particualar, this can happen when sending to a greylisting
1448 server, but other circumstances could also provoke similar problems.
1449 I have changed the default so that the retry time for these errors is now
1450 based a combination of the sender and recipient addresses. This change
1451 can be overridden by setting address_retry_include_sender=false in the
1452 smtp transport.

1720PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1722 Unfortunately, if there is a major crisis, such as a disk failure,
1723 tcp-wrappers gives "deny", whereas what one would like would be some
1724 kind of temporary error. A kludge has been added to help with this.
1725 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1726 554 error is used if errno is still zero or contains ENOENT (which occurs
1727 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1728 451 error is used.

1764PH/01 The code for finding all the local interface addresses on a FreeBSD
1765 system running IPv6 was broken. This may well have applied to all BSD
1766 systems, as well as to others that have similar system calls. The broken
1767 code found IPv4 interfaces correctly, but gave incorrect values for the
1768 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1769 that it would not match correctly against @[] and not recognize the IPv6
1770 addresses as local.

1811 syntactically invalid From: or Reply-to: line, and a filter used this to
1812 generate an autoreply, and therefore failed to obtain an address for the
1813 autoreply, Exim could try to deliver to a non-existent relative file
1814 name, causing unrelated and misleading errors. What now happens is that
1815 it logs this as a hard delivery error, but does not attempt to create a

1833 non-existent - all you got was a failure to exec. I have made two
1834 changes:
1835
1836 (a) Failures to set uid/gid, the current directory, or a process leader
1837 in a subprocess such as that created by queryprogram now generate
1838 suitable debugging ouput when -d is set.
1839
1840 (b) The queryprogram router detects when it is not running as root,
1841 outputs suitable debugging information if -d is set, and then runs
1842 the subprocess without attempting to change uid/gid.

1847PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1848 additional section of a DNS packet that returns MX or SRV records.
1849 Instead, it always explicitly searches for A/AAAA records. This avoids
1850 major problems that occur when a DNS server includes only records of one
1851 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1852 fixed another bug: if SRV records were looked up and the corresponding
1853 address records were *not* found in the additional section, the port
1854 values from the SRV records were lost.

ea49d0e1
PH
1856PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

1860PH/18 If quota_warn_message contains a From: header, Exim now refrains from

1863
727071f8
PH
1864PH/19 When calculating a retry time, Exim used to measure the "time since
1865 failure" by looking at the "first failed" field in the retry record. Now
1866 it does not use this if it is later than than the arrival time of the
1867 message. Instead it uses the arrival time. This makes for better
1868 behaviour in cases where some deliveries succeed, thus re-setting the
1869 "first failed" field. An example is a quota failure for a huge message
1870 when small messages continue to be delivered. Without this change, the
1871 "time since failure" will always be short, possible causing more frequent
1872 delivery attempts for the huge message than are intended.

PH
1969PH/42 The content-scanning code uses fopen() to create files in which to put
1970 message data. Previously it was not paying any attention to the mode of
1971 the files. Exim runs with umask(0) because the rest of the code creates
1972 files with open(), and sets the required mode explicitly. Thus, these
1973 files were ending up world-writeable. This was not a big issue, because,
1974 being within the spool directory, they were not world-accessible. I have
1975 created a function called modefopen, which takes an additional mode
1976 argument. It sets umask(777), creates the file, chmods it to the required
1977 mode, then resets the umask. All the relevant calls to fopen() in the
1978 content scanning code have been changed to use this function.

1986PH/45 When the plaintext authenticator is running as a client, the server's
1987 challenges are checked to ensure they are valid base64 strings. By
1988 default, the authentication attempt is cancelled if an invalid string is
1989 received. Setting client_ignore_invalid_base64 true ignores these errors.
1990 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1991 they are received. Thus, the responses can be made to depend on the
1992 challenges. If an invalid string is ignored, an empty string is placed in
1993 the variable.

2013PH/52 Two bugs concerned with error handling when the smtp transport is
2014 used in LMTP mode:
2015
2016 (i) Exim was not creating retry information for temporary errors given
2017 for individual recipients after the DATA command when the smtp transport
2018 was used in LMTP mode. This meant that they could be retried too
2019 frequently, and not timed out correctly.
2020
2021 (ii) Exim was setting the flag that allows error details to be returned
2022 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2023 recipients that were returned after the DATA command.
2024
2025PH/53 This is related to PH/52, but is more general: for any failing address,
2026 when detailed error information was permitted to be returned to the
2027 sender, but the error was temporary, then after the final timeout, only
2028 "retry timeout exceeded" was returned. Now it returns the full error as
2029 well as "retry timeout exceeded".

2099PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2100 function verify_get_ident() calls ip_connect() to connect a socket, but
2101 if the "connect()" function timed out, ip_connect() used to close the
2102 socket. However, verify_get_ident() also closes the socket later, and in
2103 between Exim writes to the log, which may get opened at this point. When
2104 the socket was closed in ip_connect(), the log could get the same file
2105 descriptor number as the socket. This naturally causes chaos. The fix is
2106 not to close the socket in ip_connect(); the socket should be closed by
2107 the function that creates it. There was only one place in the code where
2108 this was missing, in the iplookup router, which I don't think anybody now
2109 uses, but I've fixed it anyway.

2132
2133 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2134 string.
2135
2136 (3) Reset the variables that are obtained from the first argument of
2137 ${prvscheck and used in the second argument before leaving the code,
2138 because their memory is reclaimed, so using them afterwards may do
2139 silly things.
2140
2141 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2142 one (it's much easier than Tom thought :-).
2143
2144 (5) Because of (4), we can now allow for the use of $prvscheck_result

PH
2165PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2166 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2167 not being looked up in the rDNS to get a host name, Exim was showing the
2168 IP address twice in Received: lines, even though the IP addresses were
2169 identical. For example:
2170
2171 Received: from [1.2.3.4] (helo=[1.2.3.4])
2172
2173 However, if the real host name was known, it was omitting the HELO data
2174 if it matched the actual IP address. This has been tidied up so that it
2175 doesn't show the same IP address twice.

2201PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2203
2204 Auto-submitted: auto-generated
2205
2206 in the messages that it generates (bounce messages and others, such as
2207 warnings). In the case of bounce messages for non-SMTP mesages, there was
2208 also a typo: it was using "Auto_submitted" (underscore instead of
2209 hyphen). Since every message generated by Exim is necessarily in response
2210 to another message, thes have all been changed to:
2211
2212 Auto-Submitted: auto-replied
2213
2214 in accordance with these statements in the RFC:
2215
2216 The auto-replied keyword:
2217
2218 - SHOULD be used on messages sent in direct response to another
2219 message by an automatic process,
2220
2221 - MUST NOT be used on manually-generated messages,

2223 - MAY be used on Delivery Status Notifications (DSNs) and Message
2224 Disposition Notifications (MDNs),

2264PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2266 the IP address, check_host() was doing a simple string comparison with
2267 addresses acquired from the DNS when checking that the found name did
2268 have the original IP as one of its addresses. Since any found IPv6
2269 addresses are likely to be in abbreviated form, the comparison could
2270 fail. Luckily, there already exists a function for doing the comparison
2271 by converting both addresses to binary, so now that is used instead of
2272 the text comparison.

2389PH/23 Applied a patch to fix problems with exim-4.52 while doing radius

2391
2392 - Error returned from rc_read_config was caught wrongly
2393 - Username/password not passed on to radius server due to wrong length.

2395 The presumption is that some radiusclient API changes for 4.51/PH/17

2570 with the definition in sysexits.h (which is #included earlier).
2571 Fortunately, Exim does not actually use EX_OK. The code used to try to
2572 preserve the sysexits.h value, by assumimg that macro definitions were
2573 scanned for macro replacements. I have been disabused of this notion,
2574 so now the code just undefines EX_OK before #including unistd.h.

2579 This seems wrong - if the receiver was accepting one byte at a time it
2580 would take for ever. The timeout is now adjusted when this happens. It
2581 doesn't have to be particularly precise.

2788 to test Sieve filters that use "vacation".
2789
2790PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2791 that changes the way the GnuTLS parameters are stored in the cache file.
2792 The new format can be generated externally. For backward compatibility,
2793 if the data in the cache doesn't make sense, Exim assumes it has read an
2794 old-format file, and it generates new data and writes a new file. This
2795 means that you can't go back to an older release without removing the
2796 file.
2797
2798PH/03 A redirect router that has both "unseen" and "one_time" set does not
2799 work if there are any delivery delays because "one_time" forces the
2800 parent to be marked "delivered", so its unseen clone is never tried
2801 again. For this reason, Exim now forbids the simultaneous setting of
2802 these two options.
2803
2804PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2805 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2806 entry if you want to know the details. The fix, however, neglected to
2807 consider the case when local delivery batching is involved. The test for
2808 "previously delivered" was not happening when checking to see if an
2809 address could be batched with a previous (undelivered) one; under
2810 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2811 address.

PH
2812
2813PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2814 in its include files, and this causes problems building Exim.
2815
2816PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2817 header_syntax) but Exim was just ignoring anything given after a slash.
2818 In particular, this caused confusion with an attempt to use "verify =
2819 reverse_host_lookup/defer_ok". An error is now given when options are
2820 supplied for verify items that do not have them. (Maybe reverse_host_
2821 lookup should have a defer_ok option, but that's a different point.)
2822
2823PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2824 defined by RFC 821) to 2048, because there were problems with some AUTH

2873PH/19 When an Exim process that is running as root has to create an Exim log
2874 file, it does so in a subprocess that runs as exim:exim so as to get the
2875 ownership right at creation (otherwise, other Exim processes might see
2876 the file with the wrong ownership). There was no test for failure of this
2877 fork() call, which would lead to the process getting stuck as it waited
2878 for a non-existent subprocess. Forks do occasionally fail when resources
2879 run out. I reviewed all the other calls to fork(); they all seem to check
2880 for failure.

2882PH/20 When checking for unexpected SMTP input at connect time (before writing

2885 the result was a log entry for a synchronization error with an empty
2886 string after "input=" when read() returned zero. If read() returned -1
2887 (an event I could not check), uninitialized data bytes were printed.

PH
2899PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2900 hadn't been configured. The fix is from Juergen Kreileder, who
2901 understands it better than I do:
2902
2903 "Here's what I see happening with three configured cyrus_sasl
2904 authenticators configured (plain, login, cram-md5):
2905
2906 On startup auth_cyrus_sasl_init() gets called for each of these.
2907 This means three calls to sasl_listmech() without a specified mech_list.
2908 => SASL tests which mechs of all available mechs actually work
2909 => three warnings about OTP not working
2910 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2911
2912 With the patch, sasl_listmech() also gets called three times. But now
2913 SASL's mech_list option is set to the server_mech specified in the the
2914 authenticator. Or in other words, the answer from sasl_listmech()
2915 gets limited to just the mech you're testing for (which is different
2916 for each call.)
2917 => the return list contains just 'plain' or 'login', 'cram-md5' or
2918 nothing depending on the value of ob->server_mech.
2919
2920 I've just tested the patch: Authentication still works fine,
2921 unavailable mechs specified in the exim configuration are still
2922 caught, and the auth.log warnings about OTP are gone."

PH
2986PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2987 the grounds that routing the same address twice would always produce the
2988 same answer. This might have been true once, but it is certainly no
2989 longer true now. Routing a child address may depend on the previous
2990 routing that produced that child. Some complicated redirection strategies
2991 went wrong when messages had multiple recipients, and made Exim's
2992 behaviour dependent on the order in which the addresses were given.
2993
2994 I have moved the duplicate checking until after the routing is complete.
2995 Exim scans the addresses that are assigned to local and remote
2996 transports, and removes any duplicates. This means that more work will be
2997 done, as duplicates will always all be routed, but duplicates are
2998 presumably rare, so I don't expect this is of any significance.
2999
3000 For deliveries to pipes, files, and autoreplies, the duplicate checking
3001 still happens during the routing process, since they are not going to be
3002 routed further.

3046 successful delivery. Such timeouts include transport filter timeouts. For
3047 consistency with the overall process timeout, these timeouts are now
3048 treated as errors, giving rise to delivery failures by default. However,
3049 there is now a new Boolean option for the pipe transport called
3050 timeout_defer, which, if set TRUE, converts the failures into defers for
3051 both kinds of timeout. A transport filter timeout is now identified in

3061A note about Exim versions 4.44 and 4.50
3062----------------------------------------
3063
3064Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3065changes of various kinds. As a consequence, a big documentation update was
3066needed. This delayed the release for rather longer than seemed good, especially
3067in the light of a couple of (minor) security issues. Therefore, the changes
3068that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3069release. So 4.44 and 4.50 are in effect two different branches that both start
3070from 4.43.
3071
3072I have left the 4.50 change log unchanged; it contains all the changes since
30734.43. The change log for 4.44 is below; many of its items are identical to
3074those for 4.50. This seems to be the most sensible way to preserve the
3075historical information.

3095 was being done only for the command run by the queryprogram router. It is

3097 filters, and the commands run by the lmtp and pipe transports.

3102 descriptors. Exim was using setrlimit() to set 1000 as a large value
3103 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3104 systems. I've change it so that if it can't get 1000, it tries for 256.

316425. Narrowed the window for a race in the daemon that could cause it to ignore
3165 SIGCHLD signals. This is not a major problem, because they are used only to
3166 wake it up if nothing else does.
3167

PH
316826. A malformed maildirsize file could cause Exim to calculate negative values
3169 for the mailbox size or file count. Odd effects could occur as a result.
3170 The maildirsize information is now recalculated if the size or filecount
3171 end up negative.
3172

PH
317327. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3174 support for a long time. Removed HAVE_SYS_VFS_H.

PH
317829. In an address list, if the pattern was not a regular expression, an empty
3179 subject address (from a bounce message) matched only if the pattern was an
3180 empty string. Non-empty patterns were not even tested. This was the wrong
3181 because it is perfectly reasonable to use an empty address as part of a
3182 database query. An empty address is now tested by patterns that are
3183 lookups. However, all the other forms of pattern expect the subject to
3184 contain a local part and a domain, and therefore, for them, an empty
3185 address still always fails if the pattern is not itself empty.
3186
d8ef3577
PH
318730. Exim went into a mad DNS loop when attempting to do a callout where the
3188 host was specified on an smtp transport, and looking it up yielded more
3189 than one IP address.
3190
5cb8cbc6
PH
319131. Re-factored the code for checking spool and log partition space into a
3192 function that finds that data and another that does the check. The former
3193 is then used to implement four new variables: $spool_space, $log_space,
3194 $spool_inodes, and $log_inodes.
3195

PH
319632. The RFC2047 encoding function was originally intended for short strings
3197 such as real names; it was not keeping to the 75-character limit for
3198 encoded words that the RFC imposes. It now respects the limit, and
3199 generates multiple encoded words if necessary. To be on the safe side, I
3200 have increased the buffer size for the ${rfc2047: expansion operator from
3201 1024 to 2048 bytes.
3202
063b1e99
PH
320333. It is now permitted to omit both strings after an "if" condition; if the
3204 condition is true, the result is "true". As before, when the second string
3205 is omitted, a false condition yields an empty string. This makes it less
3206 cumbersome to write custom ACL and router conditions.
3207
652e1b65
PH
320834. Failure to deliver a bounce message always caused it to be frozen, even if
3209 there was an errors_to setting on the router. The errors_to setting is now
3210 respected.
3211
6f0c9a4f
PH
321235. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3213 canonical form (fully expanded) before being placed in
3214 $sender_host_address.
3215
33397d19
PH
321636. The table in the code that translates DNS record types into text (T_A to
3217 "A" for instance) was missing entries for NS and CNAME. It is just possible
3218 that this could have caused confusion if both these types were looked up
3219 for the same domain, because the text type is used as part of Exim's
3220 per-process caching. But the chance of anyone hitting this buglet seems
3221 very small.
3222
7bb56e1f
PH
322337. The dnsdb lookup has been extended in a number of ways.
3224
3225 (1) There is a new type, "zns", which walks up the domain tree until it
3226 finds some nameserver records. It should be used with care.
3227
ea3bc19b
PH
3228 (2) There is a new type, "mxh", which is like "mx" except that it returns
3229 just the host names, not the priorities.
3230
3231 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3232 looked up. The behaviour when one of the lookups defers can be
3233 controlled by a keyword.
7bb56e1f 3234
ea3bc19b 3235 (4) It is now possible to specify the separator character for use when
7bb56e1f 3236 multiple records are returned.
33397d19 3237
0bcb2a0e
PH
323838. The dnslists ACL condition has been extended: it is now possible to supply
3239 a list of IP addresses and/or domains to be looked up in a particular DNS
3240 domain.

324239. Added log_selector=+queue_time_overall.

PH
324440. When running the queue in the test harness, wait just a tad after forking a
3245 delivery process, to get repeatability of debugging output.
3246
de365ded
PH
324741. Include certificate and key file names in error message when GnuTLS fails
3248 to set them up, because the GnuTLS error message doesn't include the name
3249 of the failing file when there is a problem reading it.
3250

325142. Allow both -bf and -bF in the same test run.

PH
325544. The "Exiscan patch" is now merged into the mainline Exim source.
3256
325745. Sometimes the final signoff response after QUIT could fail to get
3258 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3259 < 0 before doing a fflush(). This bug looks as though it goes back to the
3260 introduction of TLS in release 3.20, but "sometimes" must have been rare
3261 because the tests only now provoked it.

326346. Reset the locale to "C" after calling embedded Perl, in case it was changed
3264 (this can affect the format of dates).

PH
326647. exim_tidydb, when checking for the continued existence of a message for
3267 which it has found a message-specific retry record, was not finding
3268 messages that were in split spool directories. Consequently, it was
3269 deleting retry records that should have stayed in existence.

PH
327148. Steve fixed some bugs in eximstats.
3272
327349. The SPA authentication driver was not abandoning authentication and moving
3274 on to the next authenticator when an expansion was forced to fail,
3275 contradicting the general specification for all authenticators. Instead it
3276 was generating a temporary error. It now behaves as specified.
3277

PH
327850. The default ordering of permitted cipher suites for GnuTLS was pessimal
3279 (the order specifies the preference for clients). The order is now AES256,
3280 AES128, 3DES, ARCFOUR128.

328251. Small patch to Sieve code - explicitly set From: when generating an

PH
328552. Exim crashed if a remote delivery caused a very long error message to be
3286 recorded - for instance if somebody sent an entire SpamAssassin report back
3287 as a large number of 550 error lines. This bug was coincidentally fixed by
3288 increasing the size of one of Exim's internal buffers (big_buffer) that
3289 happened as part of the Exiscan merge. However, to be on the safe side, I
3290 have made the code more robust (and fixed the comments that describe what
3291 is going on).
3292
55ee9ee3
PH
329353. Now that there can be additional text after "Completed" in log lines (if
3294 the queue_time_overall log selector is set), a one-byte patch to exigrep
3295 was needed to allow it to recognize "Completed" as not the last thing in
3296 the line.

329854. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3299 patch that reportedly fixes this has been added. I am not expert enough to
3300 create a test for it. This is what the patch creator wrote:
3301
3302 "I found a little strange behaviour of ldap code when working with
3303 Windows 2003 AD Domain, where users was placed in more than one
3304 Organization Units. When I tried to give exim partial DN, the exit code
3305 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3306 But simultaneously result of request was absolutely normal ldap result,
3307 so I produce this patch..."
3308
3295e65b
PH
3309 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3310 REFERENCE, so I have modified the code to exclude the patch when that macro
3311 is not defined.
3312

PH
331355. Some experimental protocols are using DNS PTR records for new purposes. The
3314 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3315 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3316 leaves it alone. Component reversal etc. now happens only for IP addresses.

3322 long debug lines gets shown.

PH
332458. The exicyclog utility now does better if the number of log files to keep
3325 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3326

PH
332759. Two changes related to the smtp_active_hostname option:
3328
3329 (1) $smtp_active_hostname is now available as a variable.
3330 (2) The default for smtp_banner uses $smtp_active_hostname instead
3331 of $primary_hostname.
3332
b975ba52
PH
333360. The host_aton() function is supposed to be passed a string that is known
3334 to be a valid IP address. However, in the case of IPv6 addresses, it was
3335 not checking this. This is a hostage to fortune. Exim now panics and dies
3336 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3337 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3338 components; fortuitously, this particular loophole had already been fixed
3339 by change 4.50/55 above.
3340
3341 If there are any other similar loopholes, the new check in host_aton()
3342 itself should stop them being exploited. The report I received stated that
3343 data on the command line could provoke the exploit when Exim was running as
3344 exim, but did not say which command line option was involved. All I could
3345 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3346 running as the user.

334961. There was a buffer overflow vulnerability in the SPA authentication code
3350 (which came originally from the Samba project). I have added a test to the
3351 spa_base64_to_bits() function which I hope fixes it.

PH
335763. The daemon start-up calls getloadavg() while still root for those OS that
3358 need the first call to be done as root, but it missed one case: when
3359 deliver_queue_load_max is set with deliver_drop_privilege. This is
3360 necessary for the benefit of the queue runner, because there is no re-exec
3361 when deliver_drop_privilege is set.
3362

PH
336364. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3364 This has been fixed.
3365
60dc5e56
PH
336665. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3367 was in use, was not putting the data itself into the right store pool;
3368 consequently, it could be overwritten for a subsequent message in the same
3369 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3370 the caching.)
3371

PH
337266. Added hosts_max_try_hardlimit to the smtp transport, default 50.

PH
337467. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3375 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3376 the function were treating the return as a boolean value, which happened to
3377 work because 0=false and not-0=true, but is not correct code.
3378
7e634d24
PH
337968. The host_aton() function was not handling scoped IPv6 addresses (those
3380 with, for example, "%eth0" on the end) correctly.

338269. Fixed some compiler warnings in acl.c for the bitmaps specified with
