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

185
81f91683
PP
186PP/31 %D in printf continues to cause issues (-Wformat=security), so for

188 As part of this, removing so much warning spew let me fix some minor
189 real issues in debug logging.
190
5779e6aa
PP
191PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
192 assignment on my part. Fixed.
193
3375e053
PP
194PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
195 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
196 Janne Snabb (who went above and beyond: thank you).
197
198PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
199 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP

b87a6e0e
PP
207 GNU libc to support some of the 64-bit stuff, should not lead to
208 conflicts. Defined before os.h is pulled in, so if a given platform
209 needs to override this, it can.
210

PP
211PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
212 protection layer was required, which is not implemented.

PP
215PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built

TF
237TF/03 Make the exiwhat support code safe for signals. Previously Exim might
238 lock up or crash if it happened to be inside a call to libc when it
239 got a SIGUSR1 from exiwhat.
240
241 The SIGUSR1 handler appends the current process status to the process
242 log which is later printed by exiwhat. It used to use the general
243 purpose logging code to do this, but several functions it calls are
244 not safe for signals.
245
246 The new output code in the SIGUSR1 handler is specific to the process
247 log, and simple enough that it's easy to inspect for signal safety.
248 Removing some special cases also simplifies the general logging code.
249 Removing the spurious timestamps from the process log simplifies
250 exiwhat.
251

TF
252TF/04 Improved ratelimit ACL condition.
253
254 The /noupdate option has been deprecated in favour of /readonly which
255 has clearer semantics. The /leaky, /strict, and /readonly update modes
256 are mutually exclusive. The update mode is no longer included in the
257 database key; it just determines when the database is updated. (This
258 means that when you upgrde Exim will forget old rate measurements.)
259
260 Exim now checks that the per_* options are used with an update mode that
261 makes sense for the current ACL. For example, when Exim is processing a
262 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
263 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
264 must specify per_mail/readonly. If you omit the update mode it defaults to
265 /leaky where that makes sense (as before) or /readonly where required.
266
267 The /noupdate option is now undocumented but still supported for
268 backwards compatibility. It is equivalent to /readonly except that in
269 ACLs where /readonly is required you may specify /leaky/noupdate or
270 /strict/noupdate which are treated the same as /readonly.
271
272 A useful new feature is the /count= option. This is a generalization
273 of the per_byte option, so that you can measure the throughput of other
274 aggregate values. For example, the per_byte option is now equivalent
275 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
276
277 The per_rcpt option has been generalized using the /count= mechanism
278 (though it's more complicated than the per_byte equivalence). When it is
279 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
280 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
281 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
282 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
283 Note that using per_rcpt with a non-readonly update mode in more than
284 one ACL will cause the recipients to be double-counted. (The per_mail
285 and per_byte options don't have this problem.)
286
287 The handling of very low rates has changed slightly. If the computed rate
288 is less than the event's count (usually one) then this event is the first
289 after a long gap. In this case the rate is set to the same as this event's
290 count, so that the first message of a spam run is counted properly.
291
292 The major new feature is a mechanism for counting the rate of unique
293 events. The new per_addr option counts the number of different
294 recipients that someone has sent messages to in the last time period. It
295 behaves like per_rcpt if all the recipient addresses are different, but
296 duplicate recipient addresses do not increase the measured rate. Like
297 the /count= option this is a general mechanism, so the per_addr option
298 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
299 example, measure the rate that a client uses different sender addresses
300 with the options per_mail/unique=$sender_address. There are further
301 details in the main documentation.

850
851 Note to Michael Haardt: I had to rename some vars in sieve.c. They
852 were called 'true' and it seems that C99 defines that as a reserved
853 keyword to be used with 'bool' variable types. That means you could
854 not include C99-style headers which use bools without triggering
855 build errors in sieve.c.

871-----------------
872
873PH/01 Another patch from the Sieve maintainer.
874
6a3bceb1
PH
875PH/02 When an IPv6 address is converted to a string for single-key lookup
876 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
877 dots are used instead of colons so that keys in lsearch files need not
878 contain colons. This was done some time before quoting was made available
879 in lsearch files. However, iplsearch files do require colons in IPv6 keys
880 (notated using the quote facility) so as to distinguish them from IPv4
881 keys. This meant that lookups for IP addresses in host lists did not work
882 for iplsearch lookups.
883
884 This has been fixed by arranging for IPv6 addresses to be expressed with
885 colons if the lookup type is iplsearch. This is not incompatible, because
886 previously such lookups could never work.
887
888 The situation is now rather anomolous, since one *can* have colons in
889 ordinary lsearch keys. However, making the change in all cases is
890 incompatible and would probably break a number of configurations.
891

TK
892TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
893 version.

MH
895MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
896 conversion specification without a maximum field width, thereby enabling
897 a rogue spamd server to cause a buffer overflow. While nobody in their
898 right mind would setup Exim to query an untrusted spamd server, an
899 attacker that gains access to a server running spamd could potentially
900 exploit this vulnerability to run arbitrary code as the Exim user.

904
0f2cbd1b
MH
905MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
906 a directory entry by the name of the lookup key. Previously, if a
907 symlink pointed to a non-existing file or a file in a directory that
908 Exim lacked permissions to read, a lookup for a key matching that
909 symlink would fail. Now it is enough that a matching directory entry
910 exists, symlink or not. (Bugzilla 503.)

ddea74fa 955PH/19 It seems that peer DN values may contain newlines (and other non-printing

PH
983PH/02 In an ACL statement such as
984
985 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
986
987 if a client was not listed at all, or was listed with a value other than
988 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
989 the condition was not true (as it should be), so access was not denied.
990 The bug was that the ! inversion was incorrectly passed on to the second
991 item. This has been fixed.

994 = and & when the dns lookup returns more than one IP address.

MH
1011MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
1012 message fails, move_frozen_messages = true and ignore_bounce_errors_after

f0872424
PH
1015PH/07 There was a bug in the dovecot authenticator such that the value of
1016 $auth1 could be overwritten, and so not correctly preserved, after a
1017 successful authentication. This usually meant that the value preserved by
1018 the server_setid option was incorrect.

PH
1024PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1025 run for batched SMTP input. It is now run at the start of every message
1026 in the batch. While fixing this I discovered that the process information
1027 (output by running exiwhat) was not always getting set for -bs and -bS
1028 input. This is fixed, and it now also says "batched" for BSMTP.

5a11a7b4
PH
1079PH/27 When a message times out after an over-quota error from an Exim-imposed
1080 quota, the bounce message says "mailbox is full". This message was not
1081 being given when it was a system quota that was exceeded. It now should
1082 be the same.
1083
0e20aff9
MH
1084MH/03 Made $recipients available in local_scan(). local_scan() already has
1085 better access to the recipient list through recipients_list[], but
1086 $recipients can be useful in postmaster-provided expansion strings.

ca86f471
PH
1088PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1089 in the case of a MAIL command with additional options following the
1090 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
1091 were accidentally chopped off.
1092
a14e5636
PH
1093PH/29 SMTP synchronization checks are implemented when a command is read -
1094 there is a check that no more input is waiting when there shouldn't be
1095 any. However, for some commands, a delay in an ACL can mean that it is
1096 some time before the response is written. In this time, more input might
1097 arrive, invalidly. So now there are extra checks after an ACL has run for
1098 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1099 pipelining has not been advertised.

PH
1111PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1112 Exim which did not show up earlier: it was assuming that a call to
1113 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1114 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1115 was a macro that became an assignment, so it seemed to work. This has
1116 changed to a proper function call with a void return, hence the compile
1117 error. Exim's code has been fixed.

1128 "Completed" line in the log. When some messages of this type were

1133PH/38 The host_find_failed option in the manualroute router can now be set

PH
1138PH/39 In a list of hosts for manualroute, if one item (either because of multi-

1140 one IP address, and the following item turned out to be the local host,
1141 all the secondary addresses of the first item were incorrectly removed
1142 from the list, along with the local host and any following hosts (which

ebeaf996
PH
1145PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1146 whoever called Exim into the -H file. In the case of the daemon it was
1147 behaving confusingly. When first started, it used values for whoever
1148 started the daemon, but after a SIGHUP it used the Exim user (because it
1149 calls itself on a restart). I have changed the code so that it now always
1150 uses the Exim user.

2679d413
PH
1152PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

1154 sender address), and a DATA command is nevertheless sent (as can happen
1155 with PIPELINING or a stupid MUA), the error message that was given to the
1156 RCPT commands is included in the rejection of the DATA command. This is
1157 intended to be helpful for MUAs that show only the final error to their
1158 users.

58eb016e 1172PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1173 the response to the final '.' that terminates a message, but only in the
1174 case where the client has not sent further data following the '.'
1175 (unfortunately, this is allowed). However, in many cases there won't be
1176 any further data because there won't be any more messages to send. A call
1177 to select() can be used: if it shows that the input is "ready", there is
1178 either input waiting, or the socket has been closed. An attempt to read
1179 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1180 would have sent an OK response which the client would never have see.
563b63fa

1188Exim version 4.66
1189-----------------
1190
1191PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1192 fixed by 4.65/MH/01 (is this a record?) are fixed:
1193
1194 (i) An empty string was always treated as zero by the numeric comparison
1195 operators. This behaviour has been restored.
1196
1197 (ii) It is documented that the numeric comparison operators always treat
1198 their arguments as decimal numbers. This was broken in that numbers
1199 starting with 0 were being interpreted as octal.
1200
1201 While fixing these problems I realized that there was another issue that
1202 hadn't been noticed. Values of message_size_limit (both the global option
1203 and the transport option) were treated as octal if they started with 0.
1204 The documentation was vague. These values are now always treated as
1205 decimal, and I will make that clear in the documentation.

PH
1219PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1220 child addresses, Exim now panics and dies. Previously, because the count
1221 is held in a short int, deliveries were likely to be lost. As such a
1222 large number of recipients for a single message is ridiculous
1223 (performance will be very, very poor), I have chosen to impose a limit
1224 rather than extend the field.

1230TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1231 leftover -K file (the existence of which was triggered by #402).
1232 While we were at it, introduced process PID as part of the -K
1233 filename. This should rule out race conditions when creating
1234 these files.
1235
1236TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1237 processing considerably. Previous code took too long for large mails,
1238 triggering a timeout which in turn triggers #401.
1239
1240TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1241 in the DK code in transports.c. sendfile() is not really portable,
1242 hence the _LINUX specificness.

1244TF/01 In the add_headers option to the mail command in an Exim filter,
1245 there was a bug that Exim would claim a syntax error in any
1246 header after the first one which had an odd number of characters
1247 in the field name.

2b1c6e3a
PH
1249PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1250 callout verification, Exim cached a "reject" for the entire domain. This
1251 is correct for most verifications, but it is not correct for a recipient
1252 verification with use_sender or use_postmaster set, because in that case
1253 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1254 case of MAIL FROM:<> rejection from other early rejections (e.g.
1255 rejection of HELO). When verifying a recipient using a non-null MAIL
1256 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1257 Whatever the result of the callout, the value of the domain cache is
1258 left unchanged (for any other kind of callout, getting as far as trying
1259 RCPT means that the domain itself is ok).

1293PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1294 hostname. This is wrong, because it relates to the incoming message (and
1295 probably the interface on which it is arriving) and not to the outgoing
1296 callout (which could be using a different interface). This has been
1297 changed to use the value of the helo_data option from the smtp transport
1298 instead - this is what is used when a message is actually being sent. If
1299 there is no remote transport (possible with a router that sets up host
1300 addresses), $smtp_active_hostname is used.

14aa5a05 1302PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1303 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1304 (a) The code assumed that strncpy() returns a negative number on buffer
1305 overflow, which isn't the case. Replaced with Exim's string_format()
1306 function.
1307 (b) There were several signed/unsigned issues. I just did the minimum
1308 hacking in of casts. There is scope for a larger refactoring.
1309 (c) The code used strcasecmp() which is not a standard C function.
1310 Replaced with Exim's strcmpic() function.
1311 (d) The code set only $1; it now sets $auth1 as well.
1312 (e) A simple test gave the error "authentication client didn't specify
1313 service in request". It would seem that Dovecot has changed its
1314 interface. Fortunately there's a specification; I followed it and
1315 changed what the client sends and it appears to be working now.

1320PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1321 address A is aliased to B and C, where B exists and C does not. Without
1322 -v the output is "A verified" because verification stops after a
1323 successful redirection if more than one address is generated. However,
1324 with -v the child addresses are also verified. Exim was outputting "A
1325 failed to verify" and then showing the successful verification for C,
1326 with its parentage. It now outputs "B failed to verify", showing B's
1327 parentage before showing the successful verification of C.

1329PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1330 look up a TXT record in a specific list after matching in a combined
1331 list.
1332
322050c2
PH
1333PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1334 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1335 they consult the DNS. I had assumed they would set it the way they
1336 wanted; and indeed my experiments on Linux seem to show that in some
1337 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1338 To be on the safe side, however, I have now made the interface to
1339 host_find_byname() similar to host_find_bydns(), with an argument
1340 containing the DNS resolver options. The host_find_byname() function now
1341 sets these options at its start, just as host_find_bydns() does. The smtp
1342 transport options dns_qualify_single and dns_search_parents are passed to
1343 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1344 of host_find_byname() use the default settings of RES_DEFNAMES
1345 (qualify_single) but not RES_DNSRCH (search_parents).
1346

PH
1347PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1348 spool_read_header() do less string testing, by means of a preliminary
1349 switch on the second character of optional "-foo" lines. (This is
1350 overdue, caused by the large number of possibilities that now exist.
1351 Originally there were few.) While I was there, I also converted the
1352 str(n)cmp tests so they don't re-test the leading "-" and the first
1353 character, in the hope this might squeeze out yet more improvement.
1354

PH
1355PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1356 flag allowing group syntax was set by the header_syntax check but not
1357 turned off, possible causing trouble later; (2) The flag was not being
1358 set at all for the header_verify test, causing "group"-style headers to
1359 be rejected. I have now set it in this case, and also caused header_
1360 verify to ignore an empty address taken from a group. While doing this, I
1361 came across some other cases where the code for allowing group syntax
1362 while scanning a header line wasn't quite right (mostly, not resetting
1363 the flag correctly in the right place). These bugs could have caused
1364 trouble for malformed header lines. I hope it is now all correct.
1365
602e59e5
PH
1366PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1367 with the "reply" argument non-NULL. The code, however (which originally
1368 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1369 but it didn't always do it. This confused somebody who was copying the
1370 code for some other use. I have removed all the tests.
1371
411ef850
PH
1372PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1373 feature that was used to support insecure browsers during the U.S. crypto
1374 embargo. It requires special client support, and Exim is probably the
1375 only MTA that supported it -- and would never use it because real RSA is
1376 always available. This code has been removed, because it had the bad
1377 effect of slowing Exim down by computing (never used) parameters for the
1378 RSA_EXPORT functionality.
1379
7befa435
PH
1380PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1381 authenticator to fail if there's a tab character in the incoming data
1382 (there should never be unless someone is messing about, as it's supposed
1383 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1384 if the connection is using TLS or if the remote IP is the same as the
1385 local IP, and the "valid-client-cert option" if a client certificate has
1386 been verified.

1417
1418PH/30 Exim was sometimes attempting to deliver messages that had suffered
1419 address errors (4xx response to RCPT) over the same connection as other
1420 messages routed to the same hosts. Such deliveries are always "forced",
1421 so retry times are not inspected. This resulted in far too many retries
1422 for the affected addresses. The effect occurred only when there were more
1423 hosts than the hosts_max_try setting in the smtp transport when it had
1424 the 4xx errors. Those hosts that it had tried were not added to the list
1425 of hosts for which the message was waiting, so if all were tried, there
1426 was no problem. Two fixes have been applied:
1427
1428 (i) If there are any address or message errors in an SMTP delivery, none
1429 of the hosts (tried or untried) are now added to the list of hosts
1430 for which the message is waiting, so the message should not be a
1431 candidate for sending over the same connection that was used for a
1432 successful delivery of some other message. This seems entirely
1433 reasonable: after all the message is NOT "waiting for some host".
1434 This is so "obvious" that I'm not sure why it wasn't done
1435 previously. Hope I haven't missed anything, but it can't do any
1436 harm, as the worst effect is to miss an optimization.
1437
1438 (ii) If, despite (i), such a delivery is accidentally attempted, the
1439 routing retry time is respected, so at least it doesn't keep
1440 hammering the server.

PH
1455PH/35 The error "getsockname() failed: connection reset by peer" was being
1456 written to the panic log as well as the main log, but it isn't really
1457 panic-worthy as it just means the connection died rather early on. I have
1458 removed the panic log writing for the ECONNRESET error when getsockname()
1459 fails.
1460
48c7f9e2
PH
1461PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1462 runs only) independently of the message's sender address. This meant
1463 that, if the 4xx error was in fact related to the sender, a different
1464 message to the same recipient with a different sender could confuse
1465 things. In particualar, this can happen when sending to a greylisting
1466 server, but other circumstances could also provoke similar problems.
1467 I have changed the default so that the retry time for these errors is now
1468 based a combination of the sender and recipient addresses. This change
1469 can be overridden by setting address_retry_include_sender=false in the
1470 smtp transport.

1738PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1739 "Deny" causes Exim to reject the incoming connection with a 554 error.
1740 Unfortunately, if there is a major crisis, such as a disk failure,
1741 tcp-wrappers gives "deny", whereas what one would like would be some
1742 kind of temporary error. A kludge has been added to help with this.
1743 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1744 554 error is used if errno is still zero or contains ENOENT (which occurs
1745 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1746 451 error is used.

1782PH/01 The code for finding all the local interface addresses on a FreeBSD
1783 system running IPv6 was broken. This may well have applied to all BSD
1784 systems, as well as to others that have similar system calls. The broken
1785 code found IPv4 interfaces correctly, but gave incorrect values for the
1786 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1787 that it would not match correctly against @[] and not recognize the IPv6
1788 addresses as local.

1829 syntactically invalid From: or Reply-to: line, and a filter used this to
1830 generate an autoreply, and therefore failed to obtain an address for the
1831 autoreply, Exim could try to deliver to a non-existent relative file
1832 name, causing unrelated and misleading errors. What now happens is that
1833 it logs this as a hard delivery error, but does not attempt to create a

1851 non-existent - all you got was a failure to exec. I have made two
1852 changes:
1853
1854 (a) Failures to set uid/gid, the current directory, or a process leader
1855 in a subprocess such as that created by queryprogram now generate
1856 suitable debugging ouput when -d is set.
1857
1858 (b) The queryprogram router detects when it is not running as root,
1859 outputs suitable debugging information if -d is set, and then runs
1860 the subprocess without attempting to change uid/gid.

1865PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1866 additional section of a DNS packet that returns MX or SRV records.
1867 Instead, it always explicitly searches for A/AAAA records. This avoids
1868 major problems that occur when a DNS server includes only records of one
1869 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1870 fixed another bug: if SRV records were looked up and the corresponding
1871 address records were *not* found in the additional section, the port
1872 values from the SRV records were lost.

1874PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

1881
727071f8
PH
1882PH/19 When calculating a retry time, Exim used to measure the "time since
1883 failure" by looking at the "first failed" field in the retry record. Now
1884 it does not use this if it is later than than the arrival time of the
1885 message. Instead it uses the arrival time. This makes for better
1886 behaviour in cases where some deliveries succeed, thus re-setting the
1887 "first failed" field. An example is a quota failure for a huge message
1888 when small messages continue to be delivered. Without this change, the
1889 "time since failure" will always be short, possible causing more frequent
1890 delivery attempts for the huge message than are intended.

PH
1987PH/42 The content-scanning code uses fopen() to create files in which to put
1988 message data. Previously it was not paying any attention to the mode of
1989 the files. Exim runs with umask(0) because the rest of the code creates
1990 files with open(), and sets the required mode explicitly. Thus, these
1991 files were ending up world-writeable. This was not a big issue, because,
1992 being within the spool directory, they were not world-accessible. I have
1993 created a function called modefopen, which takes an additional mode
1994 argument. It sets umask(777), creates the file, chmods it to the required
1995 mode, then resets the umask. All the relevant calls to fopen() in the
1996 content scanning code have been changed to use this function.

2008 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2031PH/52 Two bugs concerned with error handling when the smtp transport is
2032 used in LMTP mode:
2033
2034 (i) Exim was not creating retry information for temporary errors given
2035 for individual recipients after the DATA command when the smtp transport
2036 was used in LMTP mode. This meant that they could be retried too
2037 frequently, and not timed out correctly.
2038
2039 (ii) Exim was setting the flag that allows error details to be returned
2040 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2041 recipients that were returned after the DATA command.
2042
2043PH/53 This is related to PH/52, but is more general: for any failing address,
2044 when detailed error information was permitted to be returned to the
2045 sender, but the error was temporary, then after the final timeout, only
2046 "retry timeout exceeded" was returned. Now it returns the full error as
2047 well as "retry timeout exceeded".

2117PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2118 function verify_get_ident() calls ip_connect() to connect a socket, but
2119 if the "connect()" function timed out, ip_connect() used to close the
2120 socket. However, verify_get_ident() also closes the socket later, and in
2121 between Exim writes to the log, which may get opened at this point. When
2122 the socket was closed in ip_connect(), the log could get the same file
2123 descriptor number as the socket. This naturally causes chaos. The fix is
2124 not to close the socket in ip_connect(); the socket should be closed by
2125 the function that creates it. There was only one place in the code where
2126 this was missing, in the iplookup router, which I don't think anybody now
2127 uses, but I've fixed it anyway.

2150
2151 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2152 string.
2153
2154 (3) Reset the variables that are obtained from the first argument of
2155 ${prvscheck and used in the second argument before leaving the code,
2156 because their memory is reclaimed, so using them afterwards may do
2157 silly things.
2158
2159 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2160 one (it's much easier than Tom thought :-).

2184 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2185 not being looked up in the rDNS to get a host name, Exim was showing the
2186 IP address twice in Received: lines, even though the IP addresses were
2187 identical. For example:
2188
2189 Received: from [1.2.3.4] (helo=[1.2.3.4])
2190
2191 However, if the real host name was known, it was omitting the HELO data
2192 if it matched the actual IP address. This has been tidied up so that it
2193 doesn't show the same IP address twice.

2221
2222 Auto-submitted: auto-generated

2224 in the messages that it generates (bounce messages and others, such as
2225 warnings). In the case of bounce messages for non-SMTP mesages, there was
2226 also a typo: it was using "Auto_submitted" (underscore instead of
2227 hyphen). Since every message generated by Exim is necessarily in response
2228 to another message, thes have all been changed to:
2229
2230 Auto-Submitted: auto-replied
2231
2232 in accordance with these statements in the RFC:
2233
2234 The auto-replied keyword:
2235
2236 - SHOULD be used on messages sent in direct response to another

2285 addresses acquired from the DNS when checking that the found name did
2286 have the original IP as one of its addresses. Since any found IPv6
2287 addresses are likely to be in abbreviated form, the comparison could
2288 fail. Luckily, there already exists a function for doing the comparison
2289 by converting both addresses to binary, so now that is used instead of
2290 the text comparison.

2374PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
2375 only if the host matched helo_try_verify_hosts, which caused the
2376 verification to occur when the EHLO/HELO command was issued. The ACL just
2377 tested the remembered result. Now, if a previous verification attempt has
2378 not happened, "verify = helo" does it there and then.

2588 with the definition in sysexits.h (which is #included earlier).
2589 Fortunately, Exim does not actually use EX_OK. The code used to try to
2590 preserve the sysexits.h value, by assumimg that macro definitions were
2591 scanned for macro replacements. I have been disabused of this notion,
2592 so now the code just undefines EX_OK before #including unistd.h.

2597 This seems wrong - if the receiver was accepting one byte at a time it
2598 would take for ever. The timeout is now adjusted when this happens. It
2599 doesn't have to be particularly precise.

2775 is now fixed, and I tidied up some of the mua_wrapper messages at the
2776 same time.

2807
2808PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2809 that changes the way the GnuTLS parameters are stored in the cache file.
2810 The new format can be generated externally. For backward compatibility,
2811 if the data in the cache doesn't make sense, Exim assumes it has read an
2812 old-format file, and it generates new data and writes a new file. This
2813 means that you can't go back to an older release without removing the
2814 file.
2815
2816PH/03 A redirect router that has both "unseen" and "one_time" set does not
2817 work if there are any delivery delays because "one_time" forces the
2818 parent to be marked "delivered", so its unseen clone is never tried
2819 again. For this reason, Exim now forbids the simultaneous setting of
2820 these two options.
2821
2822PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2823 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2824 entry if you want to know the details. The fix, however, neglected to
2825 consider the case when local delivery batching is involved. The test for
2826 "previously delivered" was not happening when checking to see if an
2827 address could be batched with a previous (undelivered) one; under
2828 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2829 address.

2830
2831PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2833
2834PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2835 header_syntax) but Exim was just ignoring anything given after a slash.
2836 In particular, this caused confusion with an attempt to use "verify =
2837 reverse_host_lookup/defer_ok". An error is now given when options are
2838 supplied for verify items that do not have them. (Maybe reverse_host_
2839 lookup should have a defer_ok option, but that's a different point.)
2840
2841PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2891PH/19 When an Exim process that is running as root has to create an Exim log
2892 file, it does so in a subprocess that runs as exim:exim so as to get the
2893 ownership right at creation (otherwise, other Exim processes might see
2894 the file with the wrong ownership). There was no test for failure of this
2895 fork() call, which would lead to the process getting stuck as it waited
2896 for a non-existent subprocess. Forks do occasionally fail when resources
2897 run out. I reviewed all the other calls to fork(); they all seem to check
2898 for failure.

2900PH/20 When checking for unexpected SMTP input at connect time (before writing

2903 the result was a log entry for a synchronization error with an empty
2904 string after "input=" when read() returned zero. If read() returned -1
2905 (an event I could not check), uninitialized data bytes were printed.

PH
2917PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2918 hadn't been configured. The fix is from Juergen Kreileder, who
2919 understands it better than I do:
2920
2921 "Here's what I see happening with three configured cyrus_sasl
2922 authenticators configured (plain, login, cram-md5):
2923
2924 On startup auth_cyrus_sasl_init() gets called for each of these.
2925 This means three calls to sasl_listmech() without a specified mech_list.
2926 => SASL tests which mechs of all available mechs actually work
2927 => three warnings about OTP not working
2928 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2929
2930 With the patch, sasl_listmech() also gets called three times. But now
2931 SASL's mech_list option is set to the server_mech specified in the the
2932 authenticator. Or in other words, the answer from sasl_listmech()
2933 gets limited to just the mech you're testing for (which is different
2934 for each call.)
2935 => the return list contains just 'plain' or 'login', 'cram-md5' or
2936 nothing depending on the value of ob->server_mech.
2937
2938 I've just tested the patch: Authentication still works fine,
2939 unavailable mechs specified in the exim configuration are still
2940 caught, and the auth.log warnings about OTP are gone."

PH
3004PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3005 the grounds that routing the same address twice would always produce the
3006 same answer. This might have been true once, but it is certainly no
3007 longer true now. Routing a child address may depend on the previous
3008 routing that produced that child. Some complicated redirection strategies
3009 went wrong when messages had multiple recipients, and made Exim's
3010 behaviour dependent on the order in which the addresses were given.
3011
3012 I have moved the duplicate checking until after the routing is complete.
3013 Exim scans the addresses that are assigned to local and remote
3014 transports, and removes any duplicates. This means that more work will be
3015 done, as duplicates will always all be routed, but duplicates are
3016 presumably rare, so I don't expect this is of any significance.
3017
3018 For deliveries to pipes, files, and autoreplies, the duplicate checking
3019 still happens during the routing process, since they are not going to be
3020 routed further.

3065 consistency with the overall process timeout, these timeouts are now
3066 treated as errors, giving rise to delivery failures by default. However,
3067 there is now a new Boolean option for the pipe transport called
3068 timeout_defer, which, if set TRUE, converts the failures into defers for
3069 both kinds of timeout. A transport filter timeout is now identified in

3079A note about Exim versions 4.44 and 4.50
3080----------------------------------------
3081
3082Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3083changes of various kinds. As a consequence, a big documentation update was
3084needed. This delayed the release for rather longer than seemed good, especially
3085in the light of a couple of (minor) security issues. Therefore, the changes
3086that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3087release. So 4.44 and 4.50 are in effect two different branches that both start
3088from 4.43.
3089
3090I have left the 4.50 change log unchanged; it contains all the changes since
30914.43. The change log for 4.44 is below; many of its items are identical to
3092those for 4.50. This seems to be the most sensible way to preserve the
3093historical information.

3115 filters, and the commands run by the lmtp and pipe transports.

3122 systems. I've change it so that if it can't get 1000, it tries for 256.

3163 handles timeouts, both on the server side and network timeouts. Renamed the
3164 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).

316621. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3167 It is now set to "smtps".

PH
316922. $host_address is now set to the target address during the checking of
3170 ignore_target_hosts.
3171
317223. When checking ignore_target_hosts for an ipliteral router, no host name was
3173 being passed; this would have caused $sender_host_name to have been used if
3174 matching the list had actually called for a host name (not very likely,
3175 since this list is usually IP addresses). A host name is now passed as
3176 "[x.x.x.x]".
3177

PH
317824. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3179 code that specifies a non-restarting handler (typically sigaction() in
3180 modern systems) in an attempt to fix a rare and obscure crash bug.
3181
318225. Narrowed the window for a race in the daemon that could cause it to ignore
3183 SIGCHLD signals. This is not a major problem, because they are used only to
3184 wake it up if nothing else does.
3185

PH
318626. A malformed maildirsize file could cause Exim to calculate negative values
3187 for the mailbox size or file count. Odd effects could occur as a result.
3188 The maildirsize information is now recalculated if the size or filecount
3189 end up negative.

PH
319127. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3192 support for a long time. Removed HAVE_SYS_VFS_H.

PH
319629. In an address list, if the pattern was not a regular expression, an empty
3197 subject address (from a bounce message) matched only if the pattern was an
3198 empty string. Non-empty patterns were not even tested. This was the wrong
3199 because it is perfectly reasonable to use an empty address as part of a
3200 database query. An empty address is now tested by patterns that are
3201 lookups. However, all the other forms of pattern expect the subject to
3202 contain a local part and a domain, and therefore, for them, an empty
3203 address still always fails if the pattern is not itself empty.
3204

PH
320530. Exim went into a mad DNS loop when attempting to do a callout where the
3206 host was specified on an smtp transport, and looking it up yielded more
3207 than one IP address.
3208

PH
320931. Re-factored the code for checking spool and log partition space into a
3210 function that finds that data and another that does the check. The former
3211 is then used to implement four new variables: $spool_space, $log_space,
3212 $spool_inodes, and $log_inodes.
3213

PH
321432. The RFC2047 encoding function was originally intended for short strings
3215 such as real names; it was not keeping to the 75-character limit for
3216 encoded words that the RFC imposes. It now respects the limit, and
3217 generates multiple encoded words if necessary. To be on the safe side, I
3218 have increased the buffer size for the ${rfc2047: expansion operator from
3219 1024 to 2048 bytes.
3220

PH
322133. It is now permitted to omit both strings after an "if" condition; if the
3222 condition is true, the result is "true". As before, when the second string
3223 is omitted, a false condition yields an empty string. This makes it less
3224 cumbersome to write custom ACL and router conditions.
3225
652e1b65
PH
322634. Failure to deliver a bounce message always caused it to be frozen, even if
3227 there was an errors_to setting on the router. The errors_to setting is now
3228 respected.
3229

PH
323035. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3231 canonical form (fully expanded) before being placed in
3232 $sender_host_address.
3233

PH
323436. The table in the code that translates DNS record types into text (T_A to
3235 "A" for instance) was missing entries for NS and CNAME. It is just possible
3236 that this could have caused confusion if both these types were looked up
3237 for the same domain, because the text type is used as part of Exim's
3238 per-process caching. But the chance of anyone hitting this buglet seems
3239 very small.
3240
7bb56e1f
PH
324137. The dnsdb lookup has been extended in a number of ways.
3242
3243 (1) There is a new type, "zns", which walks up the domain tree until it
3244 finds some nameserver records. It should be used with care.
3245
ea3bc19b
PH
3246 (2) There is a new type, "mxh", which is like "mx" except that it returns
3247 just the host names, not the priorities.
3248
3249 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3250 looked up. The behaviour when one of the lookups defers can be
3251 controlled by a keyword.
7bb56e1f 3252
ea3bc19b 3253 (4) It is now possible to specify the separator character for use when
7bb56e1f 3254 multiple records are returned.
33397d19 3255
0bcb2a0e
PH
325638. The dnslists ACL condition has been extended: it is now possible to supply
3257 a list of IP addresses and/or domains to be looked up in a particular DNS
3258 domain.

326240. When running the queue in the test harness, wait just a tad after forking a
3263 delivery process, to get repeatability of debugging output.

PH
326541. Include certificate and key file names in error message when GnuTLS fails
3266 to set them up, because the GnuTLS error message doesn't include the name
3267 of the failing file when there is a problem reading it.

PH
327344. The "Exiscan patch" is now merged into the mainline Exim source.
3274
327545. Sometimes the final signoff response after QUIT could fail to get
3276 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3277 < 0 before doing a fflush(). This bug looks as though it goes back to the
3278 introduction of TLS in release 3.20, but "sometimes" must have been rare
3279 because the tests only now provoked it.

328146. Reset the locale to "C" after calling embedded Perl, in case it was changed
3282 (this can affect the format of dates).

PH
328447. exim_tidydb, when checking for the continued existence of a message for
3285 which it has found a message-specific retry record, was not finding
3286 messages that were in split spool directories. Consequently, it was
3287 deleting retry records that should have stayed in existence.

328948. Steve fixed some bugs in eximstats.
3290
329149. The SPA authentication driver was not abandoning authentication and moving
3292 on to the next authenticator when an expansion was forced to fail,
3293 contradicting the general specification for all authenticators. Instead it
3294 was generating a temporary error. It now behaves as specified.
3295

PH
329650. The default ordering of permitted cipher suites for GnuTLS was pessimal
3297 (the order specifies the preference for clients). The order is now AES256,
3298 AES128, 3DES, ARCFOUR128.

330051. Small patch to Sieve code - explicitly set From: when generating an
3301 autoreply.

PH
330352. Exim crashed if a remote delivery caused a very long error message to be
3304 recorded - for instance if somebody sent an entire SpamAssassin report back
3305 as a large number of 550 error lines. This bug was coincidentally fixed by
3306 increasing the size of one of Exim's internal buffers (big_buffer) that
3307 happened as part of the Exiscan merge. However, to be on the safe side, I
3308 have made the code more robust (and fixed the comments that describe what
3309 is going on).
3310
55ee9ee3
PH
331153. Now that there can be additional text after "Completed" in log lines (if
3312 the queue_time_overall log selector is set), a one-byte patch to exigrep
3313 was needed to allow it to recognize "Completed" as not the last thing in
3314 the line.

PH
331654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3317 patch that reportedly fixes this has been added. I am not expert enough to
3318 create a test for it. This is what the patch creator wrote:
3319
3320 "I found a little strange behaviour of ldap code when working with
3321 Windows 2003 AD Domain, where users was placed in more than one
3322 Organization Units. When I tried to give exim partial DN, the exit code
3323 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3324 But simultaneously result of request was absolutely normal ldap result,
3325 so I produce this patch..."
3326
3295e65b
PH
3327 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3328 REFERENCE, so I have modified the code to exclude the patch when that macro
3329 is not defined.
3330

PH
333155. Some experimental protocols are using DNS PTR records for new purposes. The
3332 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3333 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3334 leaves it alone. Component reversal etc. now happens only for IP addresses.

334258. The exicyclog utility now does better if the number of log files to keep

PH
334559. Two changes related to the smtp_active_hostname option:
3346
3347 (1) $smtp_active_hostname is now available as a variable.
3348 (2) The default for smtp_banner uses $smtp_active_hostname instead
3349 of $primary_hostname.

b975ba52
PH
335160. The host_aton() function is supposed to be passed a string that is known
3352 to be a valid IP address. However, in the case of IPv6 addresses, it was
3353 not checking this. This is a hostage to fortune. Exim now panics and dies
3354 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3355 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3356 components; fortuitously, this particular loophole had already been fixed
3357 by change 4.50/55 above.
3358
3359 If there are any other similar loopholes, the new check in host_aton()
3360 itself should stop them being exploited. The report I received stated that
3361 data on the command line could provoke the exploit when Exim was running as
3362 exim, but did not say which command line option was involved. All I could
3363 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3364 running as the user.

PH
337563. The daemon start-up calls getloadavg() while still root for those OS that
3376 need the first call to be done as root, but it missed one case: when
3377 deliver_queue_load_max is set with deliver_drop_privilege. This is
3378 necessary for the benefit of the queue runner, because there is no re-exec
3379 when deliver_drop_privilege is set.
