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

96PP/14 TLS fixes for OpenSSL: support TLS 1.1 & 1.2; new "openssl_options"
97 values; set SSL_MODE_AUTO_RETRY so that OpenSSL will retry a read
98 or write after TLS renegotiation, which otherwise led to messages

126PP/19 DNS resolver init changes for NetBSD compatibility. (Risk of breakage
127 on less well tested platforms). Obviates NetBSD pkgsrc patch-ac.
128 Not seeing resolver debug output on NetBSD, but suspect this is a
129 resolver implementation change.
130

143
9e45c72b 144JH/03 ${eval } now uses 64-bit and supports a "g" suffix (like to "k" and "m").
97d17305
JH
145 This may cause build issues on older platforms.
146
17c76198
PP
147PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
148 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
149 gnutls_require_mac & gnutls_require_protocols (no longer supported).
150 Added SNI support via GnuTLS too.
af3498d6 151 Made ${randint:..} supplier available, if using not-too-old GnuTLS.

163 Patch from Wolfgang Breyha, report from Stuart Northfield.
164
08488c86
PP
165PP/29 Fix three issues highlighted by clang analyser static analysis.
166 Only crash-plausible issue would require the Cambridge-specific
167 iplookup router and a misconfiguration.
168 Report from Marcin Mirosław.
169
6475bd82
PP
170PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
171
81f91683
PP
172PP/31 %D in printf continues to cause issues (-Wformat=security), so for
173 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
174 As part of this, removing so much warning spew let me fix some minor
175 real issues in debug logging.
176
5779e6aa
PP
177PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
178 assignment on my part. Fixed.
179
3375e053
PP
180PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
181 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
182 Janne Snabb (who went above and beyond: thank you).
183
184PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
185 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
186 relatively easy to get wrong. Should also expose TLS library linkage
187 problems.
3375e053 188
9d26b8c0
PP
189PP/35 Pull in <features.h> on Linux, for some portability edge-cases of
190 64-bit ${eval} (JH/03).
191
57eb9e91 192PP/36 Define _GNU_SOURCE in exim.h; it's needed for some releases of
b87a6e0e
PP
193 GNU libc to support some of the 64-bit stuff, should not lead to
194 conflicts. Defined before os.h is pulled in, so if a given platform
195 needs to override this, it can.
196
16880d1a
PP
197PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
198 protection layer was required, which is not implemented.
199 Bugzilla 1254, patch from Wolfgang Breyha.
200
a799883d
PP
201PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
202 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
203 tls_dhparam take prime identifiers. Also unbreak combination of
204 OpenSSL+DH_params+TLSSNI.
205
3ecab157 206PP/39 Disable SSLv2 by default in OpenSSL support.

221 when unlink() failed. See also change 4.74-TF/03.
222
921b12ca
TF
223TF/03 Make the exiwhat support code safe for signals. Previously Exim might
224 lock up or crash if it happened to be inside a call to libc when it
225 got a SIGUSR1 from exiwhat.
226
227 The SIGUSR1 handler appends the current process status to the process
228 log which is later printed by exiwhat. It used to use the general
229 purpose logging code to do this, but several functions it calls are
230 not safe for signals.
231
232 The new output code in the SIGUSR1 handler is specific to the process
233 log, and simple enough that it's easy to inspect for signal safety.
234 Removing some special cases also simplifies the general logging code.
235 Removing the spurious timestamps from the process log simplifies
236 exiwhat.
237

TF
238TF/04 Improved ratelimit ACL condition.
239
240 The /noupdate option has been deprecated in favour of /readonly which
241 has clearer semantics. The /leaky, /strict, and /readonly update modes
242 are mutually exclusive. The update mode is no longer included in the
243 database key; it just determines when the database is updated. (This
244 means that when you upgrde Exim will forget old rate measurements.)
245
246 Exim now checks that the per_* options are used with an update mode that
247 makes sense for the current ACL. For example, when Exim is processing a
248 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
249 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
250 must specify per_mail/readonly. If you omit the update mode it defaults to
251 /leaky where that makes sense (as before) or /readonly where required.
252
253 The /noupdate option is now undocumented but still supported for
254 backwards compatibility. It is equivalent to /readonly except that in
255 ACLs where /readonly is required you may specify /leaky/noupdate or
256 /strict/noupdate which are treated the same as /readonly.
257
258 A useful new feature is the /count= option. This is a generalization
259 of the per_byte option, so that you can measure the throughput of other
260 aggregate values. For example, the per_byte option is now equivalent
261 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
262
263 The per_rcpt option has been generalized using the /count= mechanism
264 (though it's more complicated than the per_byte equivalence). When it is
265 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
266 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
267 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
268 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
269 Note that using per_rcpt with a non-readonly update mode in more than
270 one ACL will cause the recipients to be double-counted. (The per_mail
271 and per_byte options don't have this problem.)
272
273 The handling of very low rates has changed slightly. If the computed rate
274 is less than the event's count (usually one) then this event is the first
275 after a long gap. In this case the rate is set to the same as this event's
276 count, so that the first message of a spam run is counted properly.
277
278 The major new feature is a mechanism for counting the rate of unique
279 events. The new per_addr option counts the number of different
280 recipients that someone has sent messages to in the last time period. It
281 behaves like per_rcpt if all the recipient addresses are different, but
282 duplicate recipient addresses do not increase the measured rate. Like
283 the /count= option this is a general mechanism, so the per_addr option
284 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
285 example, measure the rate that a client uses different sender addresses
286 with the options per_mail/unique=$sender_address. There are further
287 details in the main documentation.

838 were called 'true' and it seems that C99 defines that as a reserved

860
6a3bceb1
PH
861PH/02 When an IPv6 address is converted to a string for single-key lookup
862 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
863 dots are used instead of colons so that keys in lsearch files need not
864 contain colons. This was done some time before quoting was made available
865 in lsearch files. However, iplsearch files do require colons in IPv6 keys
866 (notated using the quote facility) so as to distinguish them from IPv4
867 keys. This meant that lookups for IP addresses in host lists did not work
868 for iplsearch lookups.
869
870 This has been fixed by arranging for IPv6 addresses to be expressed with
871 colons if the lookup type is iplsearch. This is not incompatible, because
872 previously such lookups could never work.
873
874 The situation is now rather anomolous, since one *can* have colons in
875 ordinary lsearch keys. However, making the change in all cases is
876 incompatible and would probably break a number of configurations.

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

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

1079PH/29 SMTP synchronization checks are implemented when a command is read -
1080 there is a check that no more input is waiting when there shouldn't be

1082 some time before the response is written. In this time, more input might
1083 arrive, invalidly. So now there are extra checks after an ACL has run for
1084 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1085 pipelining has not been advertised.

1100 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1101 was a macro that became an assignment, so it seemed to work. This has

PH
1159 the response to the final '.' that terminates a message, but only in the
1160 case where the client has not sent further data following the '.'
1161 (unfortunately, this is allowed). However, in many cases there won't be
1162 any further data because there won't be any more messages to send. A call
1163 to select() can be used: if it shows that the input is "ready", there is
1164 either input waiting, or the socket has been closed. An attempt to read
1165 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1166 would have sent an OK response which the client would never have see.

1177PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1178 fixed by 4.65/MH/01 (is this a record?) are fixed:
1179
1180 (i) An empty string was always treated as zero by the numeric comparison
1181 operators. This behaviour has been restored.
1182
1183 (ii) It is documented that the numeric comparison operators always treat
1184 their arguments as decimal numbers. This was broken in that numbers
1185 starting with 0 were being interpreted as octal.

1187 While fixing these problems I realized that there was another issue that
1188 hadn't been noticed. Values of message_size_limit (both the global option
1189 and the transport option) were treated as octal if they started with 0.
1190 The documentation was vague. These values are now always treated as
1191 decimal, and I will make that clear in the documentation.

1208 large number of recipients for a single message is ridiculous
1209 (performance will be very, very poor), I have chosen to impose a limit

1216TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1217 leftover -K file (the existence of which was triggered by #402).

1226TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

1233 in the field name.

2b1c6e3a
PH
1235PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1236 callout verification, Exim cached a "reject" for the entire domain. This
1237 is correct for most verifications, but it is not correct for a recipient
1238 verification with use_sender or use_postmaster set, because in that case
1239 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1240 case of MAIL FROM:<> rejection from other early rejections (e.g.
1241 rejection of HELO). When verifying a recipient using a non-null MAIL
1242 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1243 Whatever the result of the callout, the value of the domain cache is
1244 left unchanged (for any other kind of callout, getting as far as trying
1245 RCPT means that the domain itself is ok).

1279PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1281 probably the interface on which it is arriving) and not to the outgoing
1282 callout (which could be using a different interface). This has been
1283 changed to use the value of the helo_data option from the smtp transport
1284 instead - this is what is used when a message is actually being sent. If
1285 there is no remote transport (possible with a router that sets up host
1286 addresses), $smtp_active_hostname is used.

7befa435 1289 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1290 (a) The code assumed that strncpy() returns a negative number on buffer
1291 overflow, which isn't the case. Replaced with Exim's string_format()
1292 function.
1293 (b) There were several signed/unsigned issues. I just did the minimum
1294 hacking in of casts. There is scope for a larger refactoring.
1295 (c) The code used strcasecmp() which is not a standard C function.
1296 Replaced with Exim's strcmpic() function.
1297 (d) The code set only $1; it now sets $auth1 as well.
1298 (e) A simple test gave the error "authentication client didn't specify
1299 service in request". It would seem that Dovecot has changed its
1300 interface. Fortunately there's a specification; I followed it and
1301 changed what the client sends and it appears to be working now.

1306PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1307 address A is aliased to B and C, where B exists and C does not. Without
1308 -v the output is "A verified" because verification stops after a
1309 successful redirection if more than one address is generated. However,
1310 with -v the child addresses are also verified. Exim was outputting "A
1311 failed to verify" and then showing the successful verification for C,
1312 with its parentage. It now outputs "B failed to verify", showing B's
1313 parentage before showing the successful verification of C.

1316 look up a TXT record in a specific list after matching in a combined

1318
322050c2
PH
1319PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1320 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1321 they consult the DNS. I had assumed they would set it the way they
1322 wanted; and indeed my experiments on Linux seem to show that in some
1323 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1324 To be on the safe side, however, I have now made the interface to
1325 host_find_byname() similar to host_find_bydns(), with an argument
1326 containing the DNS resolver options. The host_find_byname() function now
1327 sets these options at its start, just as host_find_bydns() does. The smtp
1328 transport options dns_qualify_single and dns_search_parents are passed to
1329 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1330 of host_find_byname() use the default settings of RES_DEFNAMES
1331 (qualify_single) but not RES_DNSRCH (search_parents).

1333PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1334 spool_read_header() do less string testing, by means of a preliminary
1335 switch on the second character of optional "-foo" lines. (This is
1336 overdue, caused by the large number of possibilities that now exist.
1337 Originally there were few.) While I was there, I also converted the
1338 str(n)cmp tests so they don't re-test the leading "-" and the first
1339 character, in the hope this might squeeze out yet more improvement.

PH
1341PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1342 flag allowing group syntax was set by the header_syntax check but not
1343 turned off, possible causing trouble later; (2) The flag was not being
1344 set at all for the header_verify test, causing "group"-style headers to
1345 be rejected. I have now set it in this case, and also caused header_
1346 verify to ignore an empty address taken from a group. While doing this, I
1347 came across some other cases where the code for allowing group syntax
1348 while scanning a header line wasn't quite right (mostly, not resetting
1349 the flag correctly in the right place). These bugs could have caused
1350 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1352PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1353 with the "reply" argument non-NULL. The code, however (which originally
1354 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1355 but it didn't always do it. This confused somebody who was copying the
1356 code for some other use. I have removed all the tests.

PH
1358PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1359 feature that was used to support insecure browsers during the U.S. crypto
1360 embargo. It requires special client support, and Exim is probably the
1361 only MTA that supported it -- and would never use it because real RSA is
1362 always available. This code has been removed, because it had the bad
1363 effect of slowing Exim down by computing (never used) parameters for the
1364 RSA_EXPORT functionality.

PH
1366PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1367 authenticator to fail if there's a tab character in the incoming data
1368 (there should never be unless someone is messing about, as it's supposed
1369 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1370 if the connection is using TLS or if the remote IP is the same as the
1371 local IP, and the "valid-client-cert option" if a client certificate has
1372 been verified.

1403
1404PH/30 Exim was sometimes attempting to deliver messages that had suffered
1405 address errors (4xx response to RCPT) over the same connection as other
1406 messages routed to the same hosts. Such deliveries are always "forced",
1407 so retry times are not inspected. This resulted in far too many retries
1408 for the affected addresses. The effect occurred only when there were more
1409 hosts than the hosts_max_try setting in the smtp transport when it had
1410 the 4xx errors. Those hosts that it had tried were not added to the list
1411 of hosts for which the message was waiting, so if all were tried, there
1412 was no problem. Two fixes have been applied:
1413
1414 (i) If there are any address or message errors in an SMTP delivery, none
1415 of the hosts (tried or untried) are now added to the list of hosts
1416 for which the message is waiting, so the message should not be a
1417 candidate for sending over the same connection that was used for a
1418 successful delivery of some other message. This seems entirely
1419 reasonable: after all the message is NOT "waiting for some host".
1420 This is so "obvious" that I'm not sure why it wasn't done
1421 previously. Hope I haven't missed anything, but it can't do any
1422 harm, as the worst effect is to miss an optimization.
1423
1424 (ii) If, despite (i), such a delivery is accidentally attempted, the
1425 routing retry time is respected, so at least it doesn't keep
1426 hammering the server.

1441PH/35 The error "getsockname() failed: connection reset by peer" was being
1442 written to the panic log as well as the main log, but it isn't really
1443 panic-worthy as it just means the connection died rather early on. I have
1444 removed the panic log writing for the ECONNRESET error when getsockname()
1445 fails.
1446
48c7f9e2
PH
1447PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1448 runs only) independently of the message's sender address. This meant
1449 that, if the 4xx error was in fact related to the sender, a different
1450 message to the same recipient with a different sender could confuse
1451 things. In particualar, this can happen when sending to a greylisting
1452 server, but other circumstances could also provoke similar problems.
1453 I have changed the default so that the retry time for these errors is now
1454 based a combination of the sender and recipient addresses. This change
1455 can be overridden by setting address_retry_include_sender=false in the
1456 smtp transport.

1726 Unfortunately, if there is a major crisis, such as a disk failure,
1727 tcp-wrappers gives "deny", whereas what one would like would be some
1728 kind of temporary error. A kludge has been added to help with this.
1729 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1730 554 error is used if errno is still zero or contains ENOENT (which occurs
1731 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1771 code found IPv4 interfaces correctly, but gave incorrect values for the
1772 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1773 that it would not match correctly against @[] and not recognize the IPv6
1774 addresses as local.

1817 autoreply, Exim could try to deliver to a non-existent relative file

1842 suitable debugging ouput when -d is set.

1853 Instead, it always explicitly searches for A/AAAA records. This avoids
1854 major problems that occur when a DNS server includes only records of one
1855 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1856 fixed another bug: if SRV records were looked up and the corresponding
1857 address records were *not* found in the additional section, the port
1858 values from the SRV records were lost.

1860PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1868PH/19 When calculating a retry time, Exim used to measure the "time since
1869 failure" by looking at the "first failed" field in the retry record. Now
1870 it does not use this if it is later than than the arrival time of the
1871 message. Instead it uses the arrival time. This makes for better
1872 behaviour in cases where some deliveries succeed, thus re-setting the
1873 "first failed" field. An example is a quota failure for a huge message
1874 when small messages continue to be delivered. Without this change, the
1875 "time since failure" will always be short, possible causing more frequent
1876 delivery attempts for the huge message than are intended.

PH
1973PH/42 The content-scanning code uses fopen() to create files in which to put
1974 message data. Previously it was not paying any attention to the mode of
1975 the files. Exim runs with umask(0) because the rest of the code creates
1976 files with open(), and sets the required mode explicitly. Thus, these
1977 files were ending up world-writeable. This was not a big issue, because,
1978 being within the spool directory, they were not world-accessible. I have
1979 created a function called modefopen, which takes an additional mode
1980 argument. It sets umask(777), creates the file, chmods it to the required
1981 mode, then resets the umask. All the relevant calls to fopen() in the
1982 content scanning code have been changed to use this function.

1993 received. Setting client_ignore_invalid_base64 true ignores these errors.
1994 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1995 they are received. Thus, the responses can be made to depend on the

2017PH/52 Two bugs concerned with error handling when the smtp transport is
2018 used in LMTP mode:
2019
2020 (i) Exim was not creating retry information for temporary errors given
2021 for individual recipients after the DATA command when the smtp transport
2022 was used in LMTP mode. This meant that they could be retried too
2023 frequently, and not timed out correctly.
2024
2025 (ii) Exim was setting the flag that allows error details to be returned
2026 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2027 recipients that were returned after the DATA command.
2028
2029PH/53 This is related to PH/52, but is more general: for any failing address,
2030 when detailed error information was permitted to be returned to the
2031 sender, but the error was temporary, then after the final timeout, only
2032 "retry timeout exceeded" was returned. Now it returns the full error as

2103PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2104 function verify_get_ident() calls ip_connect() to connect a socket, but
2105 if the "connect()" function timed out, ip_connect() used to close the
2106 socket. However, verify_get_ident() also closes the socket later, and in
2107 between Exim writes to the log, which may get opened at this point. When
2108 the socket was closed in ip_connect(), the log could get the same file
2109 descriptor number as the socket. This naturally causes chaos. The fix is
2110 not to close the socket in ip_connect(); the socket should be closed by
2111 the function that creates it. There was only one place in the code where
2112 this was missing, in the iplookup router, which I don't think anybody now
2113 uses, but I've fixed it anyway.

2136
2137 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2138 string.
2139
2140 (3) Reset the variables that are obtained from the first argument of
2141 ${prvscheck and used in the second argument before leaving the code,
2142 because their memory is reclaimed, so using them afterwards may do
2143 silly things.
2144
2145 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2146 one (it's much easier than Tom thought :-).

2169PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2170 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2171 not being looked up in the rDNS to get a host name, Exim was showing the
2172 IP address twice in Received: lines, even though the IP addresses were
2173 identical. For example:
2174
2175 Received: from [1.2.3.4] (helo=[1.2.3.4])
2176
2177 However, if the real host name was known, it was omitting the HELO data
2178 if it matched the actual IP address. This has been tidied up so that it
2179 doesn't show the same IP address twice.

2205PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2207
2208 Auto-submitted: auto-generated
2209
2210 in the messages that it generates (bounce messages and others, such as
2211 warnings). In the case of bounce messages for non-SMTP mesages, there was
2212 also a typo: it was using "Auto_submitted" (underscore instead of
2213 hyphen). Since every message generated by Exim is necessarily in response
2214 to another message, thes have all been changed to:
2215
2216 Auto-Submitted: auto-replied
2217
2218 in accordance with these statements in the RFC:
2219
2220 The auto-replied keyword:
2221
2222 - SHOULD be used on messages sent in direct response to another
2223 message by an automatic process,
2224

2271 addresses acquired from the DNS when checking that the found name did
2272 have the original IP as one of its addresses. Since any found IPv6
2273 addresses are likely to be in abbreviated form, the comparison could
2274 fail. Luckily, there already exists a function for doing the comparison
2275 by converting both addresses to binary, so now that is used instead of
2276 the text comparison.

2574 with the definition in sysexits.h (which is #included earlier).
2575 Fortunately, Exim does not actually use EX_OK. The code used to try to
2576 preserve the sysexits.h value, by assumimg that macro definitions were
2577 scanned for macro replacements. I have been disabused of this notion,

2583 This seems wrong - if the receiver was accepting one byte at a time it
2584 would take for ever. The timeout is now adjusted when this happens. It
2585 doesn't have to be particularly precise.

2793
2794PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2795 that changes the way the GnuTLS parameters are stored in the cache file.
2796 The new format can be generated externally. For backward compatibility,
2797 if the data in the cache doesn't make sense, Exim assumes it has read an
2798 old-format file, and it generates new data and writes a new file. This
2799 means that you can't go back to an older release without removing the
2800 file.
2801
2802PH/03 A redirect router that has both "unseen" and "one_time" set does not
2803 work if there are any delivery delays because "one_time" forces the
2804 parent to be marked "delivered", so its unseen clone is never tried
2805 again. For this reason, Exim now forbids the simultaneous setting of
2806 these two options.
2807
2808PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2809 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2810 entry if you want to know the details. The fix, however, neglected to
2811 consider the case when local delivery batching is involved. The test for
2812 "previously delivered" was not happening when checking to see if an
2813 address could be batched with a previous (undelivered) one; under
2814 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2815 address.

2817PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2819
2820PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2821 header_syntax) but Exim was just ignoring anything given after a slash.
2822 In particular, this caused confusion with an attempt to use "verify =
2823 reverse_host_lookup/defer_ok". An error is now given when options are
2824 supplied for verify items that do not have them. (Maybe reverse_host_
2825 lookup should have a defer_ok option, but that's a different point.)
2826
2827PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2879 ownership right at creation (otherwise, other Exim processes might see
2880 the file with the wrong ownership). There was no test for failure of this
2881 fork() call, which would lead to the process getting stuck as it waited
2882 for a non-existent subprocess. Forks do occasionally fail when resources
2883 run out. I reviewed all the other calls to fork(); they all seem to check
2884 for failure.

2889 the result was a log entry for a synchronization error with an empty
2890 string after "input=" when read() returned zero. If read() returned -1
2891 (an event I could not check), uninitialized data bytes were printed.

PH
2903PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2904 hadn't been configured. The fix is from Juergen Kreileder, who
2905 understands it better than I do:
2906
2907 "Here's what I see happening with three configured cyrus_sasl
2908 authenticators configured (plain, login, cram-md5):
2909
2910 On startup auth_cyrus_sasl_init() gets called for each of these.
2911 This means three calls to sasl_listmech() without a specified mech_list.
2912 => SASL tests which mechs of all available mechs actually work
2913 => three warnings about OTP not working
2914 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2915
2916 With the patch, sasl_listmech() also gets called three times. But now
2917 SASL's mech_list option is set to the server_mech specified in the the
2918 authenticator. Or in other words, the answer from sasl_listmech()
2919 gets limited to just the mech you're testing for (which is different
2920 for each call.)
2921 => the return list contains just 'plain' or 'login', 'cram-md5' or
2922 nothing depending on the value of ob->server_mech.
2923
2924 I've just tested the patch: Authentication still works fine,
2925 unavailable mechs specified in the exim configuration are still

PH
2990PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2991 the grounds that routing the same address twice would always produce the
2992 same answer. This might have been true once, but it is certainly no
2993 longer true now. Routing a child address may depend on the previous
2994 routing that produced that child. Some complicated redirection strategies
2995 went wrong when messages had multiple recipients, and made Exim's
2996 behaviour dependent on the order in which the addresses were given.
2997
2998 I have moved the duplicate checking until after the routing is complete.
2999 Exim scans the addresses that are assigned to local and remote
3000 transports, and removes any duplicates. This means that more work will be
3001 done, as duplicates will always all be routed, but duplicates are
3002 presumably rare, so I don't expect this is of any significance.
3003
3004 For deliveries to pipes, files, and autoreplies, the duplicate checking
3005 still happens during the routing process, since they are not going to be
3006 routed further.

3050 successful delivery. Such timeouts include transport filter timeouts. For
3051 consistency with the overall process timeout, these timeouts are now
3052 treated as errors, giving rise to delivery failures by default. However,
3053 there is now a new Boolean option for the pipe transport called
3054 timeout_defer, which, if set TRUE, converts the failures into defers for
3055 both kinds of timeout. A transport filter timeout is now identified in

3065A note about Exim versions 4.44 and 4.50
3066----------------------------------------
3067
3068Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3069changes of various kinds. As a consequence, a big documentation update was
3070needed. This delayed the release for rather longer than seemed good, especially
3071in the light of a couple of (minor) security issues. Therefore, the changes
3072that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3073release. So 4.44 and 4.50 are in effect two different branches that both start
3074from 4.43.
3075
3076I have left the 4.50 change log unchanged; it contains all the changes since
30774.43. The change log for 4.44 is below; many of its items are identical to
3078those for 4.50. This seems to be the most sensible way to preserve the
3079historical information.

3101 filters, and the commands run by the lmtp and pipe transports.

3108 systems. I've change it so that if it can't get 1000, it tries for 256.

3160 matching the list had actually called for a host name (not very likely,
3161 since this list is usually IP addresses). A host name is now passed as
3162 "[x.x.x.x]".

PH
316424. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3165 code that specifies a non-restarting handler (typically sigaction() in
3166 modern systems) in an attempt to fix a rare and obscure crash bug.
3167
316825. Narrowed the window for a race in the daemon that could cause it to ignore
3169 SIGCHLD signals. This is not a major problem, because they are used only to
3170 wake it up if nothing else does.
3171

PH
317226. A malformed maildirsize file could cause Exim to calculate negative values
3173 for the mailbox size or file count. Odd effects could occur as a result.
3174 The maildirsize information is now recalculated if the size or filecount
3175 end up negative.

PH
317727. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3178 support for a long time. Removed HAVE_SYS_VFS_H.

PH
318229. In an address list, if the pattern was not a regular expression, an empty
3183 subject address (from a bounce message) matched only if the pattern was an
3184 empty string. Non-empty patterns were not even tested. This was the wrong
3185 because it is perfectly reasonable to use an empty address as part of a
3186 database query. An empty address is now tested by patterns that are
3187 lookups. However, all the other forms of pattern expect the subject to
3188 contain a local part and a domain, and therefore, for them, an empty
3189 address still always fails if the pattern is not itself empty.
3190

PH
319130. Exim went into a mad DNS loop when attempting to do a callout where the
3192 host was specified on an smtp transport, and looking it up yielded more
3193 than one IP address.
3194
5cb8cbc6
PH
319531. Re-factored the code for checking spool and log partition space into a
3196 function that finds that data and another that does the check. The former
3197 is then used to implement four new variables: $spool_space, $log_space,
3198 $spool_inodes, and $log_inodes.

PH
320032. The RFC2047 encoding function was originally intended for short strings
3201 such as real names; it was not keeping to the 75-character limit for
3202 encoded words that the RFC imposes. It now respects the limit, and
3203 generates multiple encoded words if necessary. To be on the safe side, I
3204 have increased the buffer size for the ${rfc2047: expansion operator from
3205 1024 to 2048 bytes.
3206
063b1e99
PH
320733. It is now permitted to omit both strings after an "if" condition; if the
3208 condition is true, the result is "true". As before, when the second string
3209 is omitted, a false condition yields an empty string. This makes it less
3210 cumbersome to write custom ACL and router conditions.
3211
652e1b65
PH
321234. Failure to deliver a bounce message always caused it to be frozen, even if
3213 there was an errors_to setting on the router. The errors_to setting is now
3214 respected.
3215
6f0c9a4f
PH
321635. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3217 canonical form (fully expanded) before being placed in
3218 $sender_host_address.
3219
33397d19
PH
322036. The table in the code that translates DNS record types into text (T_A to
3221 "A" for instance) was missing entries for NS and CNAME. It is just possible
3222 that this could have caused confusion if both these types were looked up
3223 for the same domain, because the text type is used as part of Exim's
3224 per-process caching. But the chance of anyone hitting this buglet seems
3225 very small.
3226
7bb56e1f
PH
322737. The dnsdb lookup has been extended in a number of ways.
3228
3229 (1) There is a new type, "zns", which walks up the domain tree until it
3230 finds some nameserver records. It should be used with care.
3231
ea3bc19b
PH
3232 (2) There is a new type, "mxh", which is like "mx" except that it returns
3233 just the host names, not the priorities.
3234
3235 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3236 looked up. The behaviour when one of the lookups defers can be
3237 controlled by a keyword.
7bb56e1f 3238
ea3bc19b 3239 (4) It is now possible to specify the separator character for use when
7bb56e1f 3240 multiple records are returned.
33397d19 3241
0bcb2a0e
PH
324238. The dnslists ACL condition has been extended: it is now possible to supply
3243 a list of IP addresses and/or domains to be looked up in a particular DNS
3244 domain.

PH
325141. Include certificate and key file names in error message when GnuTLS fails
3252 to set them up, because the GnuTLS error message doesn't include the name
3253 of the failing file when there is a problem reading it.

325944. The "Exiscan patch" is now merged into the mainline Exim source.
3260
326145. Sometimes the final signoff response after QUIT could fail to get
3262 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3263 < 0 before doing a fflush(). This bug looks as though it goes back to the
3264 introduction of TLS in release 3.20, but "sometimes" must have been rare
3265 because the tests only now provoked it.

326746. Reset the locale to "C" after calling embedded Perl, in case it was changed
3268 (this can affect the format of dates).

PH
327047. exim_tidydb, when checking for the continued existence of a message for
3271 which it has found a message-specific retry record, was not finding
3272 messages that were in split spool directories. Consequently, it was
3273 deleting retry records that should have stayed in existence.

327548. Steve fixed some bugs in eximstats.
3276
327749. The SPA authentication driver was not abandoning authentication and moving
3278 on to the next authenticator when an expansion was forced to fail,
3279 contradicting the general specification for all authenticators. Instead it
3280 was generating a temporary error. It now behaves as specified.

PH
328250. The default ordering of permitted cipher suites for GnuTLS was pessimal
3283 (the order specifies the preference for clients). The order is now AES256,
3284 AES128, 3DES, ARCFOUR128.

328651. Small patch to Sieve code - explicitly set From: when generating an

PH
328952. Exim crashed if a remote delivery caused a very long error message to be
3290 recorded - for instance if somebody sent an entire SpamAssassin report back
3291 as a large number of 550 error lines. This bug was coincidentally fixed by
3292 increasing the size of one of Exim's internal buffers (big_buffer) that
3293 happened as part of the Exiscan merge. However, to be on the safe side, I
3294 have made the code more robust (and fixed the comments that describe what
3295 is going on).
3296
55ee9ee3
PH
329753. Now that there can be additional text after "Completed" in log lines (if
3298 the queue_time_overall log selector is set), a one-byte patch to exigrep
3299 was needed to allow it to recognize "Completed" as not the last thing in
3300 the line.

PH
330254. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3303 patch that reportedly fixes this has been added. I am not expert enough to
3304 create a test for it. This is what the patch creator wrote:
3305
3306 "I found a little strange behaviour of ldap code when working with
3307 Windows 2003 AD Domain, where users was placed in more than one
3308 Organization Units. When I tried to give exim partial DN, the exit code
3309 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3310 But simultaneously result of request was absolutely normal ldap result,
3311 so I produce this patch..."
3312
3295e65b
PH
3313 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3314 REFERENCE, so I have modified the code to exclude the patch when that macro
3315 is not defined.
3316

PH
331755. Some experimental protocols are using DNS PTR records for new purposes. The
3318 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3319 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3320 leaves it alone. Component reversal etc. now happens only for IP addresses.

332858. The exicyclog utility now does better if the number of log files to keep

PH
333159. Two changes related to the smtp_active_hostname option:
3332
3333 (1) $smtp_active_hostname is now available as a variable.
3334 (2) The default for smtp_banner uses $smtp_active_hostname instead
3335 of $primary_hostname.
3336
b975ba52
PH
333760. The host_aton() function is supposed to be passed a string that is known
3338 to be a valid IP address. However, in the case of IPv6 addresses, it was
3339 not checking this. This is a hostage to fortune. Exim now panics and dies
3340 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3341 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3342 components; fortuitously, this particular loophole had already been fixed
3343 by change 4.50/55 above.
3344
3345 If there are any other similar loopholes, the new check in host_aton()
3346 itself should stop them being exploited. The report I received stated that
3347 data on the command line could provoke the exploit when Exim was running as
3348 exim, but did not say which command line option was involved. All I could
3349 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3350 running as the user.

PH
336163. The daemon start-up calls getloadavg() while still root for those OS that
3362 need the first call to be done as root, but it missed one case: when
3363 deliver_queue_load_max is set with deliver_drop_privilege. This is
3364 necessary for the benefit of the queue runner, because there is no re-exec
3365 when deliver_drop_privilege is set.

PH
336764. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3368 This has been fixed.
3369
60dc5e56
PH
337065. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3371 was in use, was not putting the data itself into the right store pool;
3372 consequently, it could be overwritten for a subsequent message in the same
3373 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3374 the caching.)
3375

PH
337666. Added hosts_max_try_hardlimit to the smtp transport, default 50.

PH
337867. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3379 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3380 the function were treating the return as a boolean value, which happened to
3381 work because 0=false and not-0=true, but is not correct code.
3382
7e634d24
PH
338368. The host_aton() function was not handling scoped IPv6 addresses (those
3384 with, for example, "%eth0" on the end) correctly.
