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

90PP/14 TLS fixes for OpenSSL: support TLS 1.1 & 1.2; new "openssl_options"
91 values; set SSL_MODE_AUTO_RETRY so that OpenSSL will retry a read
92 or write after TLS renegotiation, which otherwise led to messages
93 "Got SSL error 2".

120PP/19 DNS resolver init changes for NetBSD compatibility. (Risk of breakage
121 on less well tested platforms). Obviates NetBSD pkgsrc patch-ac.
122 Not seeing resolver debug output on NetBSD, but suspect this is a
123 resolver implementation change.
124
c6e95d22

139 This may cause build issues on older platforms.
140
17c76198
PP
141PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
142 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
143 gnutls_require_mac & gnutls_require_protocols (no longer supported).
144 Added SNI support via GnuTLS too.

165
81f91683
PP
166PP/31 %D in printf continues to cause issues (-Wformat=security), so for
167 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
168 As part of this, removing so much warning spew let me fix some minor
169 real issues in debug logging.
170
5779e6aa
PP
171PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
172 assignment on my part. Fixed.
173
3375e053
PP
174PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
175 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
176 Janne Snabb (who went above and beyond: thank you).
177
178PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
179 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
180 relatively easy to get wrong. Should also expose TLS library linkage
181 problems.

b87a6e0e
PP
187 GNU libc to support some of the 64-bit stuff, should not lead to
188 conflicts. Defined before os.h is pulled in, so if a given platform
189 needs to override this, it can.

PP
195PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
196 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
197 tls_dhparam take prime identifiers. Also unbreak combination of
198 OpenSSL+DH_params+TLSSNI.

216
921b12ca
TF
217TF/03 Make the exiwhat support code safe for signals. Previously Exim might
218 lock up or crash if it happened to be inside a call to libc when it
219 got a SIGUSR1 from exiwhat.
220
221 The SIGUSR1 handler appends the current process status to the process
222 log which is later printed by exiwhat. It used to use the general
223 purpose logging code to do this, but several functions it calls are
224 not safe for signals.
225
226 The new output code in the SIGUSR1 handler is specific to the process
227 log, and simple enough that it's easy to inspect for signal safety.
228 Removing some special cases also simplifies the general logging code.
229 Removing the spurious timestamps from the process log simplifies
230 exiwhat.
231
c99ce5c9
TF
232TF/04 Improved ratelimit ACL condition.
233
234 The /noupdate option has been deprecated in favour of /readonly which
235 has clearer semantics. The /leaky, /strict, and /readonly update modes
236 are mutually exclusive. The update mode is no longer included in the
237 database key; it just determines when the database is updated. (This
238 means that when you upgrde Exim will forget old rate measurements.)
239
240 Exim now checks that the per_* options are used with an update mode that
241 makes sense for the current ACL. For example, when Exim is processing a
242 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
243 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
244 must specify per_mail/readonly. If you omit the update mode it defaults to
245 /leaky where that makes sense (as before) or /readonly where required.
246
247 The /noupdate option is now undocumented but still supported for
248 backwards compatibility. It is equivalent to /readonly except that in
249 ACLs where /readonly is required you may specify /leaky/noupdate or
250 /strict/noupdate which are treated the same as /readonly.
251
252 A useful new feature is the /count= option. This is a generalization
253 of the per_byte option, so that you can measure the throughput of other
254 aggregate values. For example, the per_byte option is now equivalent
255 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
256
257 The per_rcpt option has been generalized using the /count= mechanism
258 (though it's more complicated than the per_byte equivalence). When it is
259 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
260 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
261 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
262 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
263 Note that using per_rcpt with a non-readonly update mode in more than
264 one ACL will cause the recipients to be double-counted. (The per_mail
265 and per_byte options don't have this problem.)
266
267 The handling of very low rates has changed slightly. If the computed rate
268 is less than the event's count (usually one) then this event is the first
269 after a long gap. In this case the rate is set to the same as this event's
270 count, so that the first message of a spam run is counted properly.
271
272 The major new feature is a mechanism for counting the rate of unique
273 events. The new per_addr option counts the number of different
274 recipients that someone has sent messages to in the last time period. It
275 behaves like per_rcpt if all the recipient addresses are different, but
276 duplicate recipient addresses do not increase the measured rate. Like
277 the /count= option this is a general mechanism, so the per_addr option
278 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
279 example, measure the rate that a client uses different sender addresses
280 with the options per_mail/unique=$sender_address. There are further
281 details in the main documentation.

830
831 Note to Michael Haardt: I had to rename some vars in sieve.c. They
832 were called 'true' and it seems that C99 defines that as a reserved
833 keyword to be used with 'bool' variable types. That means you could
834 not include C99-style headers which use bools without triggering
835 build errors in sieve.c.

853PH/01 Another patch from the Sieve maintainer.
854
6a3bceb1
PH
855PH/02 When an IPv6 address is converted to a string for single-key lookup
856 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
857 dots are used instead of colons so that keys in lsearch files need not
858 contain colons. This was done some time before quoting was made available
859 in lsearch files. However, iplsearch files do require colons in IPv6 keys
860 (notated using the quote facility) so as to distinguish them from IPv4
861 keys. This meant that lookups for IP addresses in host lists did not work
862 for iplsearch lookups.
863
864 This has been fixed by arranging for IPv6 addresses to be expressed with
865 colons if the lookup type is iplsearch. This is not incompatible, because
866 previously such lookups could never work.
867
868 The situation is now rather anomolous, since one *can* have colons in
869 ordinary lsearch keys. However, making the change in all cases is
870 incompatible and would probably break a number of configurations.

875MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
876 conversion specification without a maximum field width, thereby enabling
877 a rogue spamd server to cause a buffer overflow. While nobody in their
878 right mind would setup Exim to query an untrusted spamd server, an
879 attacker that gains access to a server running spamd could potentially
880 exploit this vulnerability to run arbitrary code as the Exim user.

884
0f2cbd1b
MH
885MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
886 a directory entry by the name of the lookup key. Previously, if a
887 symlink pointed to a non-existing file or a file in a directory that
888 Exim lacked permissions to read, a lookup for a key matching that
889 symlink would fail. Now it is enough that a matching directory entry
890 exists, symlink or not. (Bugzilla 503.)

967 if a client was not listed at all, or was listed with a value other than
968 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
969 the condition was not true (as it should be), so access was not denied.
970 The bug was that the ! inversion was incorrectly passed on to the second

1068PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1069 in the case of a MAIL command with additional options following the

1072
a14e5636
PH
1073PH/29 SMTP synchronization checks are implemented when a command is read -
1074 there is a check that no more input is waiting when there shouldn't be
1075 any. However, for some commands, a delay in an ACL can mean that it is
1076 some time before the response is written. In this time, more input might
1077 arrive, invalidly. So now there are extra checks after an ACL has run for
1078 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1079 pipelining has not been advertised.

PH
1091PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1092 Exim which did not show up earlier: it was assuming that a call to
1093 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1094 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1095 was a macro that became an assignment, so it seemed to work. This has
1096 changed to a proper function call with a void return, hence the compile
1097 error. Exim's code has been fixed.

1127 behaving confusingly. When first started, it used values for whoever
1128 started the daemon, but after a SIGHUP it used the Exim user (because it
1129 calls itself on a restart). I have changed the code so that it now always
1130 uses the Exim user.

1135 with PIPELINING or a stupid MUA), the error message that was given to the
1136 RCPT commands is included in the rejection of the DATA command. This is

PH
1153 the response to the final '.' that terminates a message, but only in the
1154 case where the client has not sent further data following the '.'
1155 (unfortunately, this is allowed). However, in many cases there won't be
1156 any further data because there won't be any more messages to send. A call
1157 to select() can be used: if it shows that the input is "ready", there is
1158 either input waiting, or the socket has been closed. An attempt to read
1159 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1160 would have sent an OK response which the client would never have see.

1171PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1172 fixed by 4.65/MH/01 (is this a record?) are fixed:
1173
1174 (i) An empty string was always treated as zero by the numeric comparison
1175 operators. This behaviour has been restored.
1176
1177 (ii) It is documented that the numeric comparison operators always treat
1178 their arguments as decimal numbers. This was broken in that numbers
1179 starting with 0 were being interpreted as octal.
1180
1181 While fixing these problems I realized that there was another issue that
1182 hadn't been noticed. Values of message_size_limit (both the global option
1183 and the transport option) were treated as octal if they started with 0.
1184 The documentation was vague. These values are now always treated as
1185 decimal, and I will make that clear in the documentation.

1199PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1200 child addresses, Exim now panics and dies. Previously, because the count
1201 is held in a short int, deliveries were likely to be lost. As such a
1202 large number of recipients for a single message is ridiculous
1203 (performance will be very, very poor), I have chosen to impose a limit
1204 rather than extend the field.

1210TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1211 leftover -K file (the existence of which was triggered by #402).

1214 these files.

1220TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

1227 in the field name.

PH
1229PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1230 callout verification, Exim cached a "reject" for the entire domain. This
1231 is correct for most verifications, but it is not correct for a recipient
1232 verification with use_sender or use_postmaster set, because in that case
1233 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1234 case of MAIL FROM:<> rejection from other early rejections (e.g.
1235 rejection of HELO). When verifying a recipient using a non-null MAIL
1236 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1237 Whatever the result of the callout, the value of the domain cache is
1238 left unchanged (for any other kind of callout, getting as far as trying
1239 RCPT means that the domain itself is ok).

1273PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1274 hostname. This is wrong, because it relates to the incoming message (and
1275 probably the interface on which it is arriving) and not to the outgoing
1276 callout (which could be using a different interface). This has been
1277 changed to use the value of the helo_data option from the smtp transport
1278 instead - this is what is used when a message is actually being sent. If
1279 there is no remote transport (possible with a router that sets up host
1280 addresses), $smtp_active_hostname is used.

7befa435 1283 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1284 (a) The code assumed that strncpy() returns a negative number on buffer
1285 overflow, which isn't the case. Replaced with Exim's string_format()
1286 function.
1287 (b) There were several signed/unsigned issues. I just did the minimum
1288 hacking in of casts. There is scope for a larger refactoring.
1289 (c) The code used strcasecmp() which is not a standard C function.
1290 Replaced with Exim's strcmpic() function.
1291 (d) The code set only $1; it now sets $auth1 as well.
1292 (e) A simple test gave the error "authentication client didn't specify
1293 service in request". It would seem that Dovecot has changed its
1294 interface. Fortunately there's a specification; I followed it and
1295 changed what the client sends and it appears to be working now.

1300PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1301 address A is aliased to B and C, where B exists and C does not. Without
1302 -v the output is "A verified" because verification stops after a
1303 successful redirection if more than one address is generated. However,
1304 with -v the child addresses are also verified. Exim was outputting "A
1305 failed to verify" and then showing the successful verification for C,
1306 with its parentage. It now outputs "B failed to verify", showing B's
1307 parentage before showing the successful verification of C.

1312
322050c2
PH
1313PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1314 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1315 they consult the DNS. I had assumed they would set it the way they
1316 wanted; and indeed my experiments on Linux seem to show that in some
1317 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1318 To be on the safe side, however, I have now made the interface to
1319 host_find_byname() similar to host_find_bydns(), with an argument
1320 containing the DNS resolver options. The host_find_byname() function now
1321 sets these options at its start, just as host_find_bydns() does. The smtp
1322 transport options dns_qualify_single and dns_search_parents are passed to
1323 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1324 of host_find_byname() use the default settings of RES_DEFNAMES
1325 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1327PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1328 spool_read_header() do less string testing, by means of a preliminary
1329 switch on the second character of optional "-foo" lines. (This is
1330 overdue, caused by the large number of possibilities that now exist.
1331 Originally there were few.) While I was there, I also converted the
1332 str(n)cmp tests so they don't re-test the leading "-" and the first
1333 character, in the hope this might squeeze out yet more improvement.

PH
1335PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1336 flag allowing group syntax was set by the header_syntax check but not
1337 turned off, possible causing trouble later; (2) The flag was not being
1338 set at all for the header_verify test, causing "group"-style headers to
1339 be rejected. I have now set it in this case, and also caused header_
1340 verify to ignore an empty address taken from a group. While doing this, I
1341 came across some other cases where the code for allowing group syntax
1342 while scanning a header line wasn't quite right (mostly, not resetting
1343 the flag correctly in the right place). These bugs could have caused
1344 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1346PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1347 with the "reply" argument non-NULL. The code, however (which originally
1348 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1349 but it didn't always do it. This confused somebody who was copying the
1350 code for some other use. I have removed all the tests.

PH
1352PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1353 feature that was used to support insecure browsers during the U.S. crypto
1354 embargo. It requires special client support, and Exim is probably the
1355 only MTA that supported it -- and would never use it because real RSA is
1356 always available. This code has been removed, because it had the bad
1357 effect of slowing Exim down by computing (never used) parameters for the
1358 RSA_EXPORT functionality.

PH
1360PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1361 authenticator to fail if there's a tab character in the incoming data
1362 (there should never be unless someone is messing about, as it's supposed
1363 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1364 if the connection is using TLS or if the remote IP is the same as the
1365 local IP, and the "valid-client-cert option" if a client certificate has
1366 been verified.

1397
1398PH/30 Exim was sometimes attempting to deliver messages that had suffered
1399 address errors (4xx response to RCPT) over the same connection as other
1400 messages routed to the same hosts. Such deliveries are always "forced",
1401 so retry times are not inspected. This resulted in far too many retries
1402 for the affected addresses. The effect occurred only when there were more
1403 hosts than the hosts_max_try setting in the smtp transport when it had
1404 the 4xx errors. Those hosts that it had tried were not added to the list
1405 of hosts for which the message was waiting, so if all were tried, there
1406 was no problem. Two fixes have been applied:
1407
1408 (i) If there are any address or message errors in an SMTP delivery, none
1409 of the hosts (tried or untried) are now added to the list of hosts
1410 for which the message is waiting, so the message should not be a
1411 candidate for sending over the same connection that was used for a
1412 successful delivery of some other message. This seems entirely
1413 reasonable: after all the message is NOT "waiting for some host".
1414 This is so "obvious" that I'm not sure why it wasn't done
1415 previously. Hope I haven't missed anything, but it can't do any
1416 harm, as the worst effect is to miss an optimization.
1417
1418 (ii) If, despite (i), such a delivery is accidentally attempted, the
1419 routing retry time is respected, so at least it doesn't keep
1420 hammering the server.

PH
1435PH/35 The error "getsockname() failed: connection reset by peer" was being
1436 written to the panic log as well as the main log, but it isn't really
1437 panic-worthy as it just means the connection died rather early on. I have
1438 removed the panic log writing for the ECONNRESET error when getsockname()
1439 fails.
1440
48c7f9e2
PH
1441PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1442 runs only) independently of the message's sender address. This meant
1443 that, if the 4xx error was in fact related to the sender, a different
1444 message to the same recipient with a different sender could confuse
1445 things. In particualar, this can happen when sending to a greylisting
1446 server, but other circumstances could also provoke similar problems.
1447 I have changed the default so that the retry time for these errors is now
1448 based a combination of the sender and recipient addresses. This change
1449 can be overridden by setting address_retry_include_sender=false in the
1450 smtp transport.

1718PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1720 Unfortunately, if there is a major crisis, such as a disk failure,
1721 tcp-wrappers gives "deny", whereas what one would like would be some
1722 kind of temporary error. A kludge has been added to help with this.
1723 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1724 554 error is used if errno is still zero or contains ENOENT (which occurs
1725 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1726 451 error is used.

1762PH/01 The code for finding all the local interface addresses on a FreeBSD
1763 system running IPv6 was broken. This may well have applied to all BSD

1765 code found IPv4 interfaces correctly, but gave incorrect values for the
1766 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1767 that it would not match correctly against @[] and not recognize the IPv6
1768 addresses as local.

1811 autoreply, Exim could try to deliver to a non-existent relative file

1834 (a) Failures to set uid/gid, the current directory, or a process leader
1835 in a subprocess such as that created by queryprogram now generate
1836 suitable debugging ouput when -d is set.
1837

1840 the subprocess without attempting to change uid/gid.

1845PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1846 additional section of a DNS packet that returns MX or SRV records.
1847 Instead, it always explicitly searches for A/AAAA records. This avoids
1848 major problems that occur when a DNS server includes only records of one
1849 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1850 fixed another bug: if SRV records were looked up and the corresponding
1851 address records were *not* found in the additional section, the port
1852 values from the SRV records were lost.

1854PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
1862PH/19 When calculating a retry time, Exim used to measure the "time since
1863 failure" by looking at the "first failed" field in the retry record. Now
1864 it does not use this if it is later than than the arrival time of the
1865 message. Instead it uses the arrival time. This makes for better
1866 behaviour in cases where some deliveries succeed, thus re-setting the
1867 "first failed" field. An example is a quota failure for a huge message
1868 when small messages continue to be delivered. Without this change, the
1869 "time since failure" will always be short, possible causing more frequent
1870 delivery attempts for the huge message than are intended.

PH
1967PH/42 The content-scanning code uses fopen() to create files in which to put
1968 message data. Previously it was not paying any attention to the mode of
1969 the files. Exim runs with umask(0) because the rest of the code creates
1970 files with open(), and sets the required mode explicitly. Thus, these
1971 files were ending up world-writeable. This was not a big issue, because,
1972 being within the spool directory, they were not world-accessible. I have
1973 created a function called modefopen, which takes an additional mode
1974 argument. It sets umask(777), creates the file, chmods it to the required
1975 mode, then resets the umask. All the relevant calls to fopen() in the
1976 content scanning code have been changed to use this function.

1984PH/45 When the plaintext authenticator is running as a client, the server's
1985 challenges are checked to ensure they are valid base64 strings. By
1986 default, the authentication attempt is cancelled if an invalid string is
1987 received. Setting client_ignore_invalid_base64 true ignores these errors.
1988 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1989 they are received. Thus, the responses can be made to depend on the
1990 challenges. If an invalid string is ignored, an empty string is placed in
1991 the variable.

2011PH/52 Two bugs concerned with error handling when the smtp transport is
2012 used in LMTP mode:
2013
2014 (i) Exim was not creating retry information for temporary errors given
2015 for individual recipients after the DATA command when the smtp transport
2016 was used in LMTP mode. This meant that they could be retried too
2017 frequently, and not timed out correctly.
2018
2019 (ii) Exim was setting the flag that allows error details to be returned
2020 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2021 recipients that were returned after the DATA command.
2022
2023PH/53 This is related to PH/52, but is more general: for any failing address,
2024 when detailed error information was permitted to be returned to the
2025 sender, but the error was temporary, then after the final timeout, only
2026 "retry timeout exceeded" was returned. Now it returns the full error as

2097PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2098 function verify_get_ident() calls ip_connect() to connect a socket, but
2099 if the "connect()" function timed out, ip_connect() used to close the
2100 socket. However, verify_get_ident() also closes the socket later, and in
2101 between Exim writes to the log, which may get opened at this point. When
2102 the socket was closed in ip_connect(), the log could get the same file
2103 descriptor number as the socket. This naturally causes chaos. The fix is
2104 not to close the socket in ip_connect(); the socket should be closed by
2105 the function that creates it. There was only one place in the code where
2106 this was missing, in the iplookup router, which I don't think anybody now
2107 uses, but I've fixed it anyway.

2130
2131 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2132 string.
2133
2134 (3) Reset the variables that are obtained from the first argument of
2135 ${prvscheck and used in the second argument before leaving the code,
2136 because their memory is reclaimed, so using them afterwards may do
2137 silly things.
2138
2139 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2140 one (it's much easier than Tom thought :-).

2163PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2164 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2165 not being looked up in the rDNS to get a host name, Exim was showing the
2166 IP address twice in Received: lines, even though the IP addresses were
2167 identical. For example:
2168
2169 Received: from [1.2.3.4] (helo=[1.2.3.4])
2170
2171 However, if the real host name was known, it was omitting the HELO data
2172 if it matched the actual IP address. This has been tidied up so that it
2173 doesn't show the same IP address twice.

2199PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2201
2202 Auto-submitted: auto-generated
2203
2204 in the messages that it generates (bounce messages and others, such as
2205 warnings). In the case of bounce messages for non-SMTP mesages, there was
2206 also a typo: it was using "Auto_submitted" (underscore instead of
2207 hyphen). Since every message generated by Exim is necessarily in response
2208 to another message, thes have all been changed to:
2209
2210 Auto-Submitted: auto-replied
2211
2212 in accordance with these statements in the RFC:
2213
2214 The auto-replied keyword:
2215
2216 - SHOULD be used on messages sent in direct response to another
2217 message by an automatic process,
2218

2264 the IP address, check_host() was doing a simple string comparison with
2265 addresses acquired from the DNS when checking that the found name did
2266 have the original IP as one of its addresses. Since any found IPv6
2267 addresses are likely to be in abbreviated form, the comparison could
2268 fail. Luckily, there already exists a function for doing the comparison
2269 by converting both addresses to binary, so now that is used instead of
2270 the text comparison.

PH
2387PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
2388 authentication with radiusclient 0.4.9:
2389
2390 - Error returned from rc_read_config was caught wrongly
2391 - Username/password not passed on to radius server due to wrong length.
2392
2393 The presumption is that some radiusclient API changes for 4.51/PH/17
2394 were not taken care of correctly. The code is still untested by me (my
2395 Linux distribution still has 0.3.2 of radiusclient), but it was

PH
2567PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2568 with the definition in sysexits.h (which is #included earlier).
2569 Fortunately, Exim does not actually use EX_OK. The code used to try to
2570 preserve the sysexits.h value, by assumimg that macro definitions were
2571 scanned for macro replacements. I have been disabused of this notion,
2572 so now the code just undefines EX_OK before #including unistd.h.

PH
2574PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2575 in the smtp transport. When a block could not be written in a single
2576 write() function, the timeout was being re-applied to each part-write.
2577 This seems wrong - if the receiver was accepting one byte at a time it
2578 would take for ever. The timeout is now adjusted when this happens. It
2579 doesn't have to be particularly precise.

2654 the logs files are, rather than using the compiled in default. In our
2655 case the guess is not the same as the compiled default, so the script
2656 suddenly stopped working when I started to use syslog. The patch checks
2657 to see if log_file_path is "". If so, it attempts to read it from exim

2659 falls back to the previous guessing code."

2715PH/27 If a dnslookup or manualroute router is set with verify=only, it need not

2718 read the rcpt_include_affixes from the non-existent transport. Now it

2783TK/03 Fix ACL "regex" condition not being available in MIME ACL.
2784
2785PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
2786 to test Sieve filters that use "vacation".
2787
2788PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2789 that changes the way the GnuTLS parameters are stored in the cache file.
2790 The new format can be generated externally. For backward compatibility,
2791 if the data in the cache doesn't make sense, Exim assumes it has read an
2792 old-format file, and it generates new data and writes a new file. This
2793 means that you can't go back to an older release without removing the
2794 file.
2795
2796PH/03 A redirect router that has both "unseen" and "one_time" set does not
2797 work if there are any delivery delays because "one_time" forces the
2798 parent to be marked "delivered", so its unseen clone is never tried
2799 again. For this reason, Exim now forbids the simultaneous setting of
2800 these two options.
2801
2802PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2803 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2804 entry if you want to know the details. The fix, however, neglected to
2805 consider the case when local delivery batching is involved. The test for
2806 "previously delivered" was not happening when checking to see if an
2807 address could be batched with a previous (undelivered) one; under
2808 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2809 address.
1a46a8c5
PH
2810
2811PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2812 in its include files, and this causes problems building Exim.
2813
2814PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2815 header_syntax) but Exim was just ignoring anything given after a slash.
2816 In particular, this caused confusion with an attempt to use "verify =
2817 reverse_host_lookup/defer_ok". An error is now given when options are
2818 supplied for verify items that do not have them. (Maybe reverse_host_
2819 lookup should have a defer_ok option, but that's a different point.)
2820
2821PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2822 defined by RFC 821) to 2048, because there were problems with some AUTH
2823 commands, and RFC 1869 says the size should be increased for extended
2824 SMTP commands that take arguments.

PH
2871PH/19 When an Exim process that is running as root has to create an Exim log
2872 file, it does so in a subprocess that runs as exim:exim so as to get the
2873 ownership right at creation (otherwise, other Exim processes might see
2874 the file with the wrong ownership). There was no test for failure of this
2875 fork() call, which would lead to the process getting stuck as it waited
2876 for a non-existent subprocess. Forks do occasionally fail when resources
2877 run out. I reviewed all the other calls to fork(); they all seem to check
2878 for failure.
2879
f9b9210e
PH
2880PH/20 When checking for unexpected SMTP input at connect time (before writing
2881 the banner), Exim was not dealing correctly with a non-positive return
2882 from the read() function. If the client had disconnected by this time,
2883 the result was a log entry for a synchronization error with an empty
2884 string after "input=" when read() returned zero. If read() returned -1
2885 (an event I could not check), uninitialized data bytes were printed.
2886 There were reports of junk text (parts of files, etc) appearing after
2887 "input=".

2896
c5ddb310
PH
2897PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2898 hadn't been configured. The fix is from Juergen Kreileder, who
2899 understands it better than I do:
2900
2901 "Here's what I see happening with three configured cyrus_sasl
2902 authenticators configured (plain, login, cram-md5):
2903
2904 On startup auth_cyrus_sasl_init() gets called for each of these.
2905 This means three calls to sasl_listmech() without a specified mech_list.
2906 => SASL tests which mechs of all available mechs actually work
2907 => three warnings about OTP not working
2908 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2909
2910 With the patch, sasl_listmech() also gets called three times. But now
2911 SASL's mech_list option is set to the server_mech specified in the the
2912 authenticator. Or in other words, the answer from sasl_listmech()
2913 gets limited to just the mech you're testing for (which is different
2914 for each call.)
2915 => the return list contains just 'plain' or 'login', 'cram-md5' or
2916 nothing depending on the value of ob->server_mech.
2917
2918 I've just tested the patch: Authentication still works fine,
2919 unavailable mechs specified in the exim configuration are still
2920 caught, and the auth.log warnings about OTP are gone."

d7174846
PH
2984PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2985 the grounds that routing the same address twice would always produce the
2986 same answer. This might have been true once, but it is certainly no
2987 longer true now. Routing a child address may depend on the previous
2988 routing that produced that child. Some complicated redirection strategies
2989 went wrong when messages had multiple recipients, and made Exim's
2990 behaviour dependent on the order in which the addresses were given.
2991
2992 I have moved the duplicate checking until after the routing is complete.
2993 Exim scans the addresses that are assigned to local and remote
2994 transports, and removes any duplicates. This means that more work will be
2995 done, as duplicates will always all be routed, but duplicates are
2996 presumably rare, so I don't expect this is of any significance.
2997
2998 For deliveries to pipes, files, and autoreplies, the duplicate checking
2999 still happens during the routing process, since they are not going to be
3000 routed further.

3005 connection it has accepted, or it never writes response data. The exiscan
3006 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3007 blindly assumes that writes won't block so it may never time out."

3044 successful delivery. Such timeouts include transport filter timeouts. For
3045 consistency with the overall process timeout, these timeouts are now
3046 treated as errors, giving rise to delivery failures by default. However,
3047 there is now a new Boolean option for the pipe transport called
3048 timeout_defer, which, if set TRUE, converts the failures into defers for
3049 both kinds of timeout. A transport filter timeout is now identified in

3059A note about Exim versions 4.44 and 4.50
3060----------------------------------------
3061
3062Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3063changes of various kinds. As a consequence, a big documentation update was
3064needed. This delayed the release for rather longer than seemed good, especially
3065in the light of a couple of (minor) security issues. Therefore, the changes
3066that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3067release. So 4.44 and 4.50 are in effect two different branches that both start
3068from 4.43.
3069
3070I have left the 4.50 change log unchanged; it contains all the changes since
30714.43. The change log for 4.44 is below; many of its items are identical to
3072those for 4.50. This seems to be the most sensible way to preserve the
3073historical information.

3091 5. There are several places where Exim runs a non-Exim command in a
3092 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3093 was being done only for the command run by the queryprogram router. It is
3094 now done for all such subprocesses. The other cases are: ${run, transport
3095 filters, and the commands run by the lmtp and pipe transports.

3099 7. Some older OS have a limit of 256 on the maximum number of file
3100 descriptors. Exim was using setrlimit() to set 1000 as a large value
3101 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3102 systems. I've change it so that if it can't get 1000, it tries for 256.

3151
315223. When checking ignore_target_hosts for an ipliteral router, no host name was
3153 being passed; this would have caused $sender_host_name to have been used if
3154 matching the list had actually called for a host name (not very likely,
3155 since this list is usually IP addresses). A host name is now passed as
3156 "[x.x.x.x]".

3160 modern systems) in an attempt to fix a rare and obscure crash bug.
3161
316225. Narrowed the window for a race in the daemon that could cause it to ignore
3163 SIGCHLD signals. This is not a major problem, because they are used only to
3164 wake it up if nothing else does.

316626. A malformed maildirsize file could cause Exim to calculate negative values
3167 for the mailbox size or file count. Odd effects could occur as a result.
3168 The maildirsize information is now recalculated if the size or filecount
3169 end up negative.

PH
317629. In an address list, if the pattern was not a regular expression, an empty
3177 subject address (from a bounce message) matched only if the pattern was an
3178 empty string. Non-empty patterns were not even tested. This was the wrong
3179 because it is perfectly reasonable to use an empty address as part of a
3180 database query. An empty address is now tested by patterns that are
3181 lookups. However, all the other forms of pattern expect the subject to
3182 contain a local part and a domain, and therefore, for them, an empty
3183 address still always fails if the pattern is not itself empty.

PH
318530. Exim went into a mad DNS loop when attempting to do a callout where the
3186 host was specified on an smtp transport, and looking it up yielded more
3187 than one IP address.

PH
318931. Re-factored the code for checking spool and log partition space into a
3190 function that finds that data and another that does the check. The former
3191 is then used to implement four new variables: $spool_space, $log_space,
3192 $spool_inodes, and $log_inodes.

PH
319432. The RFC2047 encoding function was originally intended for short strings
3195 such as real names; it was not keeping to the 75-character limit for
3196 encoded words that the RFC imposes. It now respects the limit, and
3197 generates multiple encoded words if necessary. To be on the safe side, I
3198 have increased the buffer size for the ${rfc2047: expansion operator from
3199 1024 to 2048 bytes.

PH
320133. It is now permitted to omit both strings after an "if" condition; if the
3202 condition is true, the result is "true". As before, when the second string
3203 is omitted, a false condition yields an empty string. This makes it less
3204 cumbersome to write custom ACL and router conditions.
3205

PH
320634. Failure to deliver a bounce message always caused it to be frozen, even if
3207 there was an errors_to setting on the router. The errors_to setting is now
3208 respected.

PH
321035. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3211 canonical form (fully expanded) before being placed in
3212 $sender_host_address.

PH
321436. The table in the code that translates DNS record types into text (T_A to
3215 "A" for instance) was missing entries for NS and CNAME. It is just possible
3216 that this could have caused confusion if both these types were looked up
3217 for the same domain, because the text type is used as part of Exim's
3218 per-process caching. But the chance of anyone hitting this buglet seems
3219 very small.
3220

PH
322137. The dnsdb lookup has been extended in a number of ways.
3222
3223 (1) There is a new type, "zns", which walks up the domain tree until it
3224 finds some nameserver records. It should be used with care.
3225
ea3bc19b
PH
3226 (2) There is a new type, "mxh", which is like "mx" except that it returns
3227 just the host names, not the priorities.
3228
3229 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19

3230 looked up. The behaviour when one of the lookups defers can be
3231 controlled by a keyword.
7bb56e1f 3232
ea3bc19b 3233 (4) It is now possible to specify the separator character for use when
7bb56e1f 3234 multiple records are returned.

PH
323638. The dnslists ACL condition has been extended: it is now possible to supply
3237 a list of IP addresses and/or domains to be looked up in a particular DNS
3238 domain.

PH
324541. Include certificate and key file names in error message when GnuTLS fails

3247 of the failing file when there is a problem reading it.

325344. The "Exiscan patch" is now merged into the mainline Exim source.
3254
325545. Sometimes the final signoff response after QUIT could fail to get
3256 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3257 < 0 before doing a fflush(). This bug looks as though it goes back to the
3258 introduction of TLS in release 3.20, but "sometimes" must have been rare
3259 because the tests only now provoked it.

PH
326447. exim_tidydb, when checking for the continued existence of a message for
3265 which it has found a message-specific retry record, was not finding
3266 messages that were in split spool directories. Consequently, it was
3267 deleting retry records that should have stayed in existence.

326948. Steve fixed some bugs in eximstats.
3270
327149. The SPA authentication driver was not abandoning authentication and moving
3272 on to the next authenticator when an expansion was forced to fail,
3273 contradicting the general specification for all authenticators. Instead it
3274 was generating a temporary error. It now behaves as specified.

PH
327650. The default ordering of permitted cipher suites for GnuTLS was pessimal
3277 (the order specifies the preference for clients). The order is now AES256,
3278 AES128, 3DES, ARCFOUR128.

PH
328352. Exim crashed if a remote delivery caused a very long error message to be
3284 recorded - for instance if somebody sent an entire SpamAssassin report back
3285 as a large number of 550 error lines. This bug was coincidentally fixed by
3286 increasing the size of one of Exim's internal buffers (big_buffer) that
3287 happened as part of the Exiscan merge. However, to be on the safe side, I
3288 have made the code more robust (and fixed the comments that describe what
3289 is going on).

PH
329153. Now that there can be additional text after "Completed" in log lines (if
3292 the queue_time_overall log selector is set), a one-byte patch to exigrep
3293 was needed to allow it to recognize "Completed" as not the last thing in
3294 the line.

PH
329654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3297 patch that reportedly fixes this has been added. I am not expert enough to
3298 create a test for it. This is what the patch creator wrote:
3299
3300 "I found a little strange behaviour of ldap code when working with
3301 Windows 2003 AD Domain, where users was placed in more than one
3302 Organization Units. When I tried to give exim partial DN, the exit code
3303 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3304 But simultaneously result of request was absolutely normal ldap result,
3305 so I produce this patch..."
3306
3295e65b
PH
3307 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3308 REFERENCE, so I have modified the code to exclude the patch when that macro
3309 is not defined.

PH
331155. Some experimental protocols are using DNS PTR records for new purposes. The
3312 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3313 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3314 leaves it alone. Component reversal etc. now happens only for IP addresses.

332258. The exicyclog utility now does better if the number of log files to keep

PH
332559. Two changes related to the smtp_active_hostname option:
3326
3327 (1) $smtp_active_hostname is now available as a variable.
3328 (2) The default for smtp_banner uses $smtp_active_hostname instead
3329 of $primary_hostname.

b975ba52
PH
333160. The host_aton() function is supposed to be passed a string that is known
3332 to be a valid IP address. However, in the case of IPv6 addresses, it was
3333 not checking this. This is a hostage to fortune. Exim now panics and dies
3334 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3335 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3336 components; fortuitously, this particular loophole had already been fixed
3337 by change 4.50/55 above.
3338
3339 If there are any other similar loopholes, the new check in host_aton()
3340 itself should stop them being exploited. The report I received stated that
3341 data on the command line could provoke the exploit when Exim was running as
3342 exim, but did not say which command line option was involved. All I could
3343 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3344 running as the user.

PH
335563. The daemon start-up calls getloadavg() while still root for those OS that
3356 need the first call to be done as root, but it missed one case: when
3357 deliver_queue_load_max is set with deliver_drop_privilege. This is
3358 necessary for the benefit of the queue runner, because there is no re-exec
3359 when deliver_drop_privilege is set.

336164. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3362 This has been fixed.
3363
60dc5e56
PH
336465. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3365 was in use, was not putting the data itself into the right store pool;
3366 consequently, it could be overwritten for a subsequent message in the same
3367 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3368 the caching.)

PH
337267. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3373 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3374 the function were treating the return as a boolean value, which happened to
3375 work because 0=false and not-0=true, but is not correct code.

337768. The host_aton() function was not handling scoped IPv6 addresses (those
3378 with, for example, "%eth0" on the end) correctly.
