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

PP
127PP/14 TLS fixes for OpenSSL: support TLS 1.1 & 1.2; new "openssl_options"
128 values; set SSL_MODE_AUTO_RETRY so that OpenSSL will retry a read
129 or write after TLS renegotiation, which otherwise led to messages
130 "Got SSL error 2".

147 failures. We appear to now support TLS1.1+ with Exim.
148

149PP/17 OpenSSL: new expansion var $tls_sni, which if used in tls_certificate
150 lets Exim select keys and certificates based upon TLS SNI from client.

157PP/19 DNS resolver init changes for NetBSD compatibility. (Risk of breakage
158 on less well tested platforms). Obviates NetBSD pkgsrc patch-ac.
159 Not seeing resolver debug output on NetBSD, but suspect this is a
160 resolver implementation change.
161

97d17305
JH
176 This may cause build issues on older platforms.
177
17c76198
PP
178PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
179 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
180 gnutls_require_mac & gnutls_require_protocols (no longer supported).
181 Added SNI support via GnuTLS too.
af3498d6 182 Made ${randint:..} supplier available, if using not-too-old GnuTLS.

201PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
202
81f91683
PP
203PP/31 %D in printf continues to cause issues (-Wformat=security), so for
204 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
205 As part of this, removing so much warning spew let me fix some minor
206 real issues in debug logging.
207
5779e6aa
PP
208PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
209 assignment on my part. Fixed.
210
3375e053
PP
211PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
212 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
213 Janne Snabb (who went above and beyond: thank you).
214
215PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
216 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
217 relatively easy to get wrong. Should also expose TLS library linkage
218 problems.

b87a6e0e
PP
224 GNU libc to support some of the 64-bit stuff, should not lead to
225 conflicts. Defined before os.h is pulled in, so if a given platform
226 needs to override this, it can.
227

PP
228PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
229 protection layer was required, which is not implemented.

PP
232PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
233 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
234 tls_dhparam take prime identifiers. Also unbreak combination of
235 OpenSSL+DH_params+TLSSNI.

252 when unlink() failed. See also change 4.74-TF/03.
253
921b12ca
TF
254TF/03 Make the exiwhat support code safe for signals. Previously Exim might
255 lock up or crash if it happened to be inside a call to libc when it
256 got a SIGUSR1 from exiwhat.
257
258 The SIGUSR1 handler appends the current process status to the process
259 log which is later printed by exiwhat. It used to use the general
260 purpose logging code to do this, but several functions it calls are
261 not safe for signals.
262
263 The new output code in the SIGUSR1 handler is specific to the process
264 log, and simple enough that it's easy to inspect for signal safety.
265 Removing some special cases also simplifies the general logging code.
266 Removing the spurious timestamps from the process log simplifies
267 exiwhat.
268
c99ce5c9
TF
269TF/04 Improved ratelimit ACL condition.
270
271 The /noupdate option has been deprecated in favour of /readonly which
272 has clearer semantics. The /leaky, /strict, and /readonly update modes
273 are mutually exclusive. The update mode is no longer included in the
274 database key; it just determines when the database is updated. (This
275 means that when you upgrde Exim will forget old rate measurements.)
276
277 Exim now checks that the per_* options are used with an update mode that
278 makes sense for the current ACL. For example, when Exim is processing a
279 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
280 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
281 must specify per_mail/readonly. If you omit the update mode it defaults to
282 /leaky where that makes sense (as before) or /readonly where required.
283
284 The /noupdate option is now undocumented but still supported for
285 backwards compatibility. It is equivalent to /readonly except that in
286 ACLs where /readonly is required you may specify /leaky/noupdate or
287 /strict/noupdate which are treated the same as /readonly.
288
289 A useful new feature is the /count= option. This is a generalization
290 of the per_byte option, so that you can measure the throughput of other
291 aggregate values. For example, the per_byte option is now equivalent
292 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
293
294 The per_rcpt option has been generalized using the /count= mechanism
295 (though it's more complicated than the per_byte equivalence). When it is
296 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
297 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
298 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
299 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
300 Note that using per_rcpt with a non-readonly update mode in more than
301 one ACL will cause the recipients to be double-counted. (The per_mail
302 and per_byte options don't have this problem.)
303
304 The handling of very low rates has changed slightly. If the computed rate
305 is less than the event's count (usually one) then this event is the first
306 after a long gap. In this case the rate is set to the same as this event's
307 count, so that the first message of a spam run is counted properly.
308
309 The major new feature is a mechanism for counting the rate of unique
310 events. The new per_addr option counts the number of different
311 recipients that someone has sent messages to in the last time period. It
312 behaves like per_rcpt if all the recipient addresses are different, but
313 duplicate recipient addresses do not increase the measured rate. Like
314 the /count= option this is a general mechanism, so the per_addr option
315 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
316 example, measure the rate that a client uses different sender addresses
317 with the options per_mail/unique=$sender_address. There are further
318 details in the main documentation.

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

890PH/01 Another patch from the Sieve maintainer.
891
6a3bceb1
PH
892PH/02 When an IPv6 address is converted to a string for single-key lookup
893 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
894 dots are used instead of colons so that keys in lsearch files need not
895 contain colons. This was done some time before quoting was made available
896 in lsearch files. However, iplsearch files do require colons in IPv6 keys
897 (notated using the quote facility) so as to distinguish them from IPv4
898 keys. This meant that lookups for IP addresses in host lists did not work
899 for iplsearch lookups.
900
901 This has been fixed by arranging for IPv6 addresses to be expressed with
902 colons if the lookup type is iplsearch. This is not incompatible, because
903 previously such lookups could never work.
904
905 The situation is now rather anomolous, since one *can* have colons in
906 ordinary lsearch keys. However, making the change in all cases is
907 incompatible and would probably break a number of configurations.
908

MH
912MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
913 conversion specification without a maximum field width, thereby enabling
914 a rogue spamd server to cause a buffer overflow. While nobody in their
915 right mind would setup Exim to query an untrusted spamd server, an
916 attacker that gains access to a server running spamd could potentially
917 exploit this vulnerability to run arbitrary code as the Exim user.

921

MH
922MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
923 a directory entry by the name of the lookup key. Previously, if a
924 symlink pointed to a non-existing file or a file in a directory that
925 Exim lacked permissions to read, a lookup for a key matching that
926 symlink would fail. Now it is enough that a matching directory entry
927 exists, symlink or not. (Bugzilla 503.)

1004 if a client was not listed at all, or was listed with a value other than
1005 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1006 the condition was not true (as it should be), so access was not denied.

PH
1110PH/29 SMTP synchronization checks are implemented when a command is read -
1111 there is a check that no more input is waiting when there shouldn't be
1112 any. However, for some commands, a delay in an ACL can mean that it is
1113 some time before the response is written. In this time, more input might
1114 arrive, invalidly. So now there are extra checks after an ACL has run for
1115 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1116 pipelining has not been advertised.

1131 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1132 was a macro that became an assignment, so it seemed to work. This has
1133 changed to a proper function call with a void return, hence the compile
1134 error. Exim's code has been fixed.

58eb016e 1189PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1190 the response to the final '.' that terminates a message, but only in the
1191 case where the client has not sent further data following the '.'
1192 (unfortunately, this is allowed). However, in many cases there won't be
1193 any further data because there won't be any more messages to send. A call
1194 to select() can be used: if it shows that the input is "ready", there is
1195 either input waiting, or the socket has been closed. An attempt to read
1196 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1197 would have sent an OK response which the client would never have see.

1205Exim version 4.66
1206-----------------
1207
1208PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1209 fixed by 4.65/MH/01 (is this a record?) are fixed:
1210
1211 (i) An empty string was always treated as zero by the numeric comparison
1212 operators. This behaviour has been restored.
1213
1214 (ii) It is documented that the numeric comparison operators always treat
1215 their arguments as decimal numbers. This was broken in that numbers
1216 starting with 0 were being interpreted as octal.
1217
1218 While fixing these problems I realized that there was another issue that
1219 hadn't been noticed. Values of message_size_limit (both the global option
1220 and the transport option) were treated as octal if they started with 0.
1221 The documentation was vague. These values are now always treated as
1222 decimal, and I will make that clear in the documentation.

PH
1236PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1237 child addresses, Exim now panics and dies. Previously, because the count
1238 is held in a short int, deliveries were likely to be lost. As such a
1239 large number of recipients for a single message is ridiculous
1240 (performance will be very, very poor), I have chosen to impose a limit
1241 rather than extend the field.

1247TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1248 leftover -K file (the existence of which was triggered by #402).
1249 While we were at it, introduced process PID as part of the -K
1250 filename. This should rule out race conditions when creating
1251 these files.
1252
1253TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1254 processing considerably. Previous code took too long for large mails,
1255 triggering a timeout which in turn triggers #401.
1256
1257TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1258 in the DK code in transports.c. sendfile() is not really portable,
1259 hence the _LINUX specificness.

1261TF/01 In the add_headers option to the mail command in an Exim filter,

1263 header after the first one which had an odd number of characters
1264 in the field name.

2b1c6e3a
PH
1266PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1267 callout verification, Exim cached a "reject" for the entire domain. This
1268 is correct for most verifications, but it is not correct for a recipient
1269 verification with use_sender or use_postmaster set, because in that case
1270 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1271 case of MAIL FROM:<> rejection from other early rejections (e.g.
1272 rejection of HELO). When verifying a recipient using a non-null MAIL
1273 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1274 Whatever the result of the callout, the value of the domain cache is
1275 left unchanged (for any other kind of callout, getting as far as trying
1276 RCPT means that the domain itself is ok).

1310PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1311 hostname. This is wrong, because it relates to the incoming message (and
1312 probably the interface on which it is arriving) and not to the outgoing
1313 callout (which could be using a different interface). This has been
1314 changed to use the value of the helo_data option from the smtp transport
1315 instead - this is what is used when a message is actually being sent. If
1316 there is no remote transport (possible with a router that sets up host
1317 addresses), $smtp_active_hostname is used.

14aa5a05 1319PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1320 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1321 (a) The code assumed that strncpy() returns a negative number on buffer
1322 overflow, which isn't the case. Replaced with Exim's string_format()
1323 function.
1324 (b) There were several signed/unsigned issues. I just did the minimum
1325 hacking in of casts. There is scope for a larger refactoring.
1326 (c) The code used strcasecmp() which is not a standard C function.
1327 Replaced with Exim's strcmpic() function.
1328 (d) The code set only $1; it now sets $auth1 as well.
1329 (e) A simple test gave the error "authentication client didn't specify
1330 service in request". It would seem that Dovecot has changed its
1331 interface. Fortunately there's a specification; I followed it and
1332 changed what the client sends and it appears to be working now.

1337PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1338 address A is aliased to B and C, where B exists and C does not. Without
1339 -v the output is "A verified" because verification stops after a
1340 successful redirection if more than one address is generated. However,
1341 with -v the child addresses are also verified. Exim was outputting "A
1342 failed to verify" and then showing the successful verification for C,
1343 with its parentage. It now outputs "B failed to verify", showing B's
1344 parentage before showing the successful verification of C.

1346PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1347 look up a TXT record in a specific list after matching in a combined
1348 list.
1349
322050c2
PH
1350PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1351 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1352 they consult the DNS. I had assumed they would set it the way they
1353 wanted; and indeed my experiments on Linux seem to show that in some
1354 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1355 To be on the safe side, however, I have now made the interface to
1356 host_find_byname() similar to host_find_bydns(), with an argument
1357 containing the DNS resolver options. The host_find_byname() function now
1358 sets these options at its start, just as host_find_bydns() does. The smtp
1359 transport options dns_qualify_single and dns_search_parents are passed to
1360 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1361 of host_find_byname() use the default settings of RES_DEFNAMES
1362 (qualify_single) but not RES_DNSRCH (search_parents).
1363

PH
1364PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1365 spool_read_header() do less string testing, by means of a preliminary
1366 switch on the second character of optional "-foo" lines. (This is
1367 overdue, caused by the large number of possibilities that now exist.
1368 Originally there were few.) While I was there, I also converted the
1369 str(n)cmp tests so they don't re-test the leading "-" and the first
1370 character, in the hope this might squeeze out yet more improvement.

PH
1372PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1373 flag allowing group syntax was set by the header_syntax check but not
1374 turned off, possible causing trouble later; (2) The flag was not being
1375 set at all for the header_verify test, causing "group"-style headers to
1376 be rejected. I have now set it in this case, and also caused header_
1377 verify to ignore an empty address taken from a group. While doing this, I
1378 came across some other cases where the code for allowing group syntax
1379 while scanning a header line wasn't quite right (mostly, not resetting
1380 the flag correctly in the right place). These bugs could have caused
1381 trouble for malformed header lines. I hope it is now all correct.
1382
602e59e5
PH
1383PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1384 with the "reply" argument non-NULL. The code, however (which originally
1385 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1386 but it didn't always do it. This confused somebody who was copying the
1387 code for some other use. I have removed all the tests.
1388
411ef850
PH
1389PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1390 feature that was used to support insecure browsers during the U.S. crypto
1391 embargo. It requires special client support, and Exim is probably the
1392 only MTA that supported it -- and would never use it because real RSA is
1393 always available. This code has been removed, because it had the bad
1394 effect of slowing Exim down by computing (never used) parameters for the
1395 RSA_EXPORT functionality.
1396
7befa435
PH
1397PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1398 authenticator to fail if there's a tab character in the incoming data
1399 (there should never be unless someone is messing about, as it's supposed
1400 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1401 if the connection is using TLS or if the remote IP is the same as the
1402 local IP, and the "valid-client-cert option" if a client certificate has
1403 been verified.

PH
1434
1435PH/30 Exim was sometimes attempting to deliver messages that had suffered
1436 address errors (4xx response to RCPT) over the same connection as other
1437 messages routed to the same hosts. Such deliveries are always "forced",
1438 so retry times are not inspected. This resulted in far too many retries
1439 for the affected addresses. The effect occurred only when there were more
1440 hosts than the hosts_max_try setting in the smtp transport when it had
1441 the 4xx errors. Those hosts that it had tried were not added to the list
1442 of hosts for which the message was waiting, so if all were tried, there
1443 was no problem. Two fixes have been applied:
1444
1445 (i) If there are any address or message errors in an SMTP delivery, none
1446 of the hosts (tried or untried) are now added to the list of hosts
1447 for which the message is waiting, so the message should not be a
1448 candidate for sending over the same connection that was used for a
1449 successful delivery of some other message. This seems entirely
1450 reasonable: after all the message is NOT "waiting for some host".
1451 This is so "obvious" that I'm not sure why it wasn't done
1452 previously. Hope I haven't missed anything, but it can't do any
1453 harm, as the worst effect is to miss an optimization.
1454
1455 (ii) If, despite (i), such a delivery is accidentally attempted, the
1456 routing retry time is respected, so at least it doesn't keep
1457 hammering the server.

520de300
PH
1472PH/35 The error "getsockname() failed: connection reset by peer" was being
1473 written to the panic log as well as the main log, but it isn't really
1474 panic-worthy as it just means the connection died rather early on. I have
1475 removed the panic log writing for the ECONNRESET error when getsockname()
1476 fails.
1477
48c7f9e2
PH
1478PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1479 runs only) independently of the message's sender address. This meant
1480 that, if the 4xx error was in fact related to the sender, a different
1481 message to the same recipient with a different sender could confuse
1482 things. In particualar, this can happen when sending to a greylisting
1483 server, but other circumstances could also provoke similar problems.
1484 I have changed the default so that the retry time for these errors is now
1485 based a combination of the sender and recipient addresses. This change
1486 can be overridden by setting address_retry_include_sender=false in the
1487 smtp transport.

1758 tcp-wrappers gives "deny", whereas what one would like would be some
1759 kind of temporary error. A kludge has been added to help with this.
1760 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1761 554 error is used if errno is still zero or contains ENOENT (which occurs
1762 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1802 code found IPv4 interfaces correctly, but gave incorrect values for the
1803 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

1848 autoreply, Exim could try to deliver to a non-existent relative file

1884 Instead, it always explicitly searches for A/AAAA records. This avoids
1885 major problems that occur when a DNS server includes only records of one
1886 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1887 fixed another bug: if SRV records were looked up and the corresponding
1888 address records were *not* found in the additional section, the port
1889 values from the SRV records were lost.

1899PH/19 When calculating a retry time, Exim used to measure the "time since
1900 failure" by looking at the "first failed" field in the retry record. Now
1901 it does not use this if it is later than than the arrival time of the
1902 message. Instead it uses the arrival time. This makes for better
1903 behaviour in cases where some deliveries succeed, thus re-setting the
1904 "first failed" field. An example is a quota failure for a huge message
1905 when small messages continue to be delivered. Without this change, the
1906 "time since failure" will always be short, possible causing more frequent
1907 delivery attempts for the huge message than are intended.

PH
2004PH/42 The content-scanning code uses fopen() to create files in which to put
2005 message data. Previously it was not paying any attention to the mode of
2006 the files. Exim runs with umask(0) because the rest of the code creates
2007 files with open(), and sets the required mode explicitly. Thus, these
2008 files were ending up world-writeable. This was not a big issue, because,
2009 being within the spool directory, they were not world-accessible. I have
2010 created a function called modefopen, which takes an additional mode
2011 argument. It sets umask(777), creates the file, chmods it to the required
2012 mode, then resets the umask. All the relevant calls to fopen() in the
2013 content scanning code have been changed to use this function.

2048PH/52 Two bugs concerned with error handling when the smtp transport is
2049 used in LMTP mode:
2050
2051 (i) Exim was not creating retry information for temporary errors given
2052 for individual recipients after the DATA command when the smtp transport
2053 was used in LMTP mode. This meant that they could be retried too
2054 frequently, and not timed out correctly.
2055
2056 (ii) Exim was setting the flag that allows error details to be returned
2057 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2058 recipients that were returned after the DATA command.
2059
2060PH/53 This is related to PH/52, but is more general: for any failing address,
2061 when detailed error information was permitted to be returned to the
2062 sender, but the error was temporary, then after the final timeout, only
2063 "retry timeout exceeded" was returned. Now it returns the full error as

2134PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2135 function verify_get_ident() calls ip_connect() to connect a socket, but
2136 if the "connect()" function timed out, ip_connect() used to close the
2137 socket. However, verify_get_ident() also closes the socket later, and in
2138 between Exim writes to the log, which may get opened at this point. When
2139 the socket was closed in ip_connect(), the log could get the same file
2140 descriptor number as the socket. This naturally causes chaos. The fix is
2141 not to close the socket in ip_connect(); the socket should be closed by
2142 the function that creates it. There was only one place in the code where
2143 this was missing, in the iplookup router, which I don't think anybody now
2144 uses, but I've fixed it anyway.

2167
2168 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2170
2171 (3) Reset the variables that are obtained from the first argument of
2172 ${prvscheck and used in the second argument before leaving the code,
2173 because their memory is reclaimed, so using them afterwards may do
2174 silly things.
2175
2176 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2177 one (it's much easier than Tom thought :-).

2201 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2202 not being looked up in the rDNS to get a host name, Exim was showing the
2203 IP address twice in Received: lines, even though the IP addresses were
2204 identical. For example:
2205
2206 Received: from [1.2.3.4] (helo=[1.2.3.4])
2207
2208 However, if the real host name was known, it was omitting the HELO data
2209 if it matched the actual IP address. This has been tidied up so that it
2210 doesn't show the same IP address twice.

2241 in the messages that it generates (bounce messages and others, such as
2242 warnings). In the case of bounce messages for non-SMTP mesages, there was
2243 also a typo: it was using "Auto_submitted" (underscore instead of
2244 hyphen). Since every message generated by Exim is necessarily in response
2245 to another message, thes have all been changed to:
2246
2247 Auto-Submitted: auto-replied
2248
2249 in accordance with these statements in the RFC:
2250

2302 addresses acquired from the DNS when checking that the found name did
2303 have the original IP as one of its addresses. Since any found IPv6
2304 addresses are likely to be in abbreviated form, the comparison could
2305 fail. Luckily, there already exists a function for doing the comparison
2306 by converting both addresses to binary, so now that is used instead of
2307 the text comparison.

2604PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2605 with the definition in sysexits.h (which is #included earlier).
2606 Fortunately, Exim does not actually use EX_OK. The code used to try to
2607 preserve the sysexits.h value, by assumimg that macro definitions were
2608 scanned for macro replacements. I have been disabused of this notion,
2609 so now the code just undefines EX_OK before #including unistd.h.

2613 write() function, the timeout was being re-applied to each part-write.
2614 This seems wrong - if the receiver was accepting one byte at a time it
2615 would take for ever. The timeout is now adjusted when this happens. It
2616 doesn't have to be particularly precise.

2770 ones like T_AAAA, and defining it itself. I've added checks for all the

2776 data, a new version was generated, as expected. It was only the case of a
2777 non-existent file that was broken.

2824
2825PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2826 that changes the way the GnuTLS parameters are stored in the cache file.
2827 The new format can be generated externally. For backward compatibility,
2828 if the data in the cache doesn't make sense, Exim assumes it has read an
2829 old-format file, and it generates new data and writes a new file. This
2830 means that you can't go back to an older release without removing the
2831 file.
2832
2833PH/03 A redirect router that has both "unseen" and "one_time" set does not
2834 work if there are any delivery delays because "one_time" forces the
2835 parent to be marked "delivered", so its unseen clone is never tried
2836 again. For this reason, Exim now forbids the simultaneous setting of
2837 these two options.

2839PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2840 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2841 entry if you want to know the details. The fix, however, neglected to
2842 consider the case when local delivery batching is involved. The test for
2843 "previously delivered" was not happening when checking to see if an
2844 address could be batched with a previous (undelivered) one; under
2845 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2846 address.

2851PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =

2853 In particular, this caused confusion with an attempt to use "verify =
2854 reverse_host_lookup/defer_ok". An error is now given when options are
2855 supplied for verify items that do not have them. (Maybe reverse_host_
2856 lookup should have a defer_ok option, but that's a different point.)

2911 the file with the wrong ownership). There was no test for failure of this
2912 fork() call, which would lead to the process getting stuck as it waited
2913 for a non-existent subprocess. Forks do occasionally fail when resources

2921 string after "input=" when read() returned zero. If read() returned -1

2934PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2935 hadn't been configured. The fix is from Juergen Kreileder, who
2936 understands it better than I do:
2937
2938 "Here's what I see happening with three configured cyrus_sasl
2939 authenticators configured (plain, login, cram-md5):
2940
2941 On startup auth_cyrus_sasl_init() gets called for each of these.
2942 This means three calls to sasl_listmech() without a specified mech_list.
2943 => SASL tests which mechs of all available mechs actually work
2944 => three warnings about OTP not working
2945 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2946
2947 With the patch, sasl_listmech() also gets called three times. But now
2948 SASL's mech_list option is set to the server_mech specified in the the
2949 authenticator. Or in other words, the answer from sasl_listmech()
2950 gets limited to just the mech you're testing for (which is different
2951 for each call.)
2952 => the return list contains just 'plain' or 'login', 'cram-md5' or
2953 nothing depending on the value of ob->server_mech.
2954
2955 I've just tested the patch: Authentication still works fine,

PH
3021PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3022 the grounds that routing the same address twice would always produce the
3023 same answer. This might have been true once, but it is certainly no
3024 longer true now. Routing a child address may depend on the previous
3025 routing that produced that child. Some complicated redirection strategies
3026 went wrong when messages had multiple recipients, and made Exim's
3027 behaviour dependent on the order in which the addresses were given.
3028
3029 I have moved the duplicate checking until after the routing is complete.
3030 Exim scans the addresses that are assigned to local and remote
3031 transports, and removes any duplicates. This means that more work will be
3032 done, as duplicates will always all be routed, but duplicates are
3033 presumably rare, so I don't expect this is of any significance.
3034
3035 For deliveries to pipes, files, and autoreplies, the duplicate checking
3036 still happens during the routing process, since they are not going to be
3037 routed further.

3082 consistency with the overall process timeout, these timeouts are now
3083 treated as errors, giving rise to delivery failures by default. However,
3084 there is now a new Boolean option for the pipe transport called

3096A note about Exim versions 4.44 and 4.50
3097----------------------------------------
3098
3099Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3100changes of various kinds. As a consequence, a big documentation update was
3101needed. This delayed the release for rather longer than seemed good, especially
3102in the light of a couple of (minor) security issues. Therefore, the changes
3103that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3104release. So 4.44 and 4.50 are in effect two different branches that both start
3105from 4.43.
3106
3107I have left the 4.50 change log unchanged; it contains all the changes since
31084.43. The change log for 4.44 is below; many of its items are identical to
3109those for 4.50. This seems to be the most sensible way to preserve the
3110historical information.

3161 $sender_address_data in subsequent conditions in the ACL statement.
3162
23c7ff99
PH
316314. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
3164
4deaf07d
PH
316515. Added a new option "connect=<time>" to callout options, to set a different
3166 connection timeout.
3167
926e1192
PH
316816. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3169 was its contents. (It was OK if the option was not defined at all.)
3170
650edc6f
PH
317117. A "Completed" log line is now written for messages that are removed from
3172 the spool by the -Mrm option.
3173
2c7db3f5
PH
317418. New variables $sender_verify_failure and $recipient_verify_failure contain
3175 information about exactly what failed.
3176
3d235903
PH
317719. Added -dd to debug only the daemon process.
3178
7c7ad977
PH
317920. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3180 handles timeouts, both on the server side and network timeouts. Renamed the
3181 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
3182
981756db
PH
318321. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3184 It is now set to "smtps".
3185
d4eb88df
PH
318622. $host_address is now set to the target address during the checking of
3187 ignore_target_hosts.
3188
318923. When checking ignore_target_hosts for an ipliteral router, no host name was
3190 being passed; this would have caused $sender_host_name to have been used if
3191 matching the list had actually called for a host name (not very likely,
3192 since this list is usually IP addresses). A host name is now passed as
3193 "[x.x.x.x]".
3194
7d468ab8
PH
319524. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3196 code that specifies a non-restarting handler (typically sigaction() in
3197 modern systems) in an attempt to fix a rare and obscure crash bug.
3198
319925. Narrowed the window for a race in the daemon that could cause it to ignore
3200 SIGCHLD signals. This is not a major problem, because they are used only to
3201 wake it up if nothing else does.
3202
62c0818f
PH
320326. A malformed maildirsize file could cause Exim to calculate negative values
3204 for the mailbox size or file count. Odd effects could occur as a result.
3205 The maildirsize information is now recalculated if the size or filecount
3206 end up negative.
3207
26034054
PH
320827. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3209 support for a long time. Removed HAVE_SYS_VFS_H.
3210
af66f652
PH
321128. Installed the latest version of exipick from John Jetmore.
3212
90af77f4
PH
321329. In an address list, if the pattern was not a regular expression, an empty
3214 subject address (from a bounce message) matched only if the pattern was an
3215 empty string. Non-empty patterns were not even tested. This was the wrong
3216 because it is perfectly reasonable to use an empty address as part of a
3217 database query. An empty address is now tested by patterns that are
3218 lookups. However, all the other forms of pattern expect the subject to
3219 contain a local part and a domain, and therefore, for them, an empty
3220 address still always fails if the pattern is not itself empty.
3221
d8ef3577
PH
322230. Exim went into a mad DNS loop when attempting to do a callout where the
3223 host was specified on an smtp transport, and looking it up yielded more
3224 than one IP address.
3225
5cb8cbc6
PH
322631. Re-factored the code for checking spool and log partition space into a
3227 function that finds that data and another that does the check. The former
3228 is then used to implement four new variables: $spool_space, $log_space,
3229 $spool_inodes, and $log_inodes.
3230
14702f5b
PH
323132. The RFC2047 encoding function was originally intended for short strings
3232 such as real names; it was not keeping to the 75-character limit for
3233 encoded words that the RFC imposes. It now respects the limit, and
3234 generates multiple encoded words if necessary. To be on the safe side, I
3235 have increased the buffer size for the ${rfc2047: expansion operator from
3236 1024 to 2048 bytes.
3237
063b1e99
PH
323833. It is now permitted to omit both strings after an "if" condition; if the
3239 condition is true, the result is "true". As before, when the second string
3240 is omitted, a false condition yields an empty string. This makes it less
3241 cumbersome to write custom ACL and router conditions.
3242
652e1b65
PH
324334. Failure to deliver a bounce message always caused it to be frozen, even if
3244 there was an errors_to setting on the router. The errors_to setting is now
3245 respected.
3246
6f0c9a4f
PH
324735. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3248 canonical form (fully expanded) before being placed in
3249 $sender_host_address.
3250
33397d19
PH
325136. The table in the code that translates DNS record types into text (T_A to
3252 "A" for instance) was missing entries for NS and CNAME. It is just possible
3253 that this could have caused confusion if both these types were looked up
3254 for the same domain, because the text type is used as part of Exim's
3255 per-process caching. But the chance of anyone hitting this buglet seems
3256 very small.
3257
7bb56e1f
PH
325837. The dnsdb lookup has been extended in a number of ways.
3259
3260 (1) There is a new type, "zns", which walks up the domain tree until it
3261 finds some nameserver records. It should be used with care.
3262
ea3bc19b
PH
3263 (2) There is a new type, "mxh", which is like "mx" except that it returns
3264 just the host names, not the priorities.
3265
3266 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3267 looked up. The behaviour when one of the lookups defers can be
3268 controlled by a keyword.
7bb56e1f 3269
ea3bc19b 3270 (4) It is now possible to specify the separator character for use when
7bb56e1f 3271 multiple records are returned.
33397d19 3272
0bcb2a0e
PH
327338. The dnslists ACL condition has been extended: it is now possible to supply
3274 a list of IP addresses and/or domains to be looked up in a particular DNS
3275 domain.
3276
2ac0e484
PH
327739. Added log_selector=+queue_time_overall.
3278
4e1fde53
PH
327940. When running the queue in the test harness, wait just a tad after forking a
3280 delivery process, to get repeatability of debugging output.
3281
de365ded
PH
328241. Include certificate and key file names in error message when GnuTLS fails
3283 to set them up, because the GnuTLS error message doesn't include the name
3284 of the failing file when there is a problem reading it.
3285
f05da2e8
PH
328642. Allow both -bf and -bF in the same test run.
3287
d6453af2
PH
328843. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3289
f7b63901
PH
329044. The "Exiscan patch" is now merged into the mainline Exim source.
3291
329245. Sometimes the final signoff response after QUIT could fail to get
3293 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3294 < 0 before doing a fflush(). This bug looks as though it goes back to the
3295 introduction of TLS in release 3.20, but "sometimes" must have been rare
3296 because the tests only now provoked it.
3297
a444213a
PH
329846. Reset the locale to "C" after calling embedded Perl, in case it was changed
3299 (this can affect the format of dates).
3300
0ec020ea
PH
330147. exim_tidydb, when checking for the continued existence of a message for
3302 which it has found a message-specific retry record, was not finding
3303 messages that were in split spool directories. Consequently, it was
3304 deleting retry records that should have stayed in existence.
3305
b1206957
PH
330648. Steve fixed some bugs in eximstats.
3307
330849. The SPA authentication driver was not abandoning authentication and moving
3309 on to the next authenticator when an expansion was forced to fail,
3310 contradicting the general specification for all authenticators. Instead it
3311 was generating a temporary error. It now behaves as specified.
3312
26dd5a95
PH
331350. The default ordering of permitted cipher suites for GnuTLS was pessimal
3314 (the order specifies the preference for clients). The order is now AES256,
3315 AES128, 3DES, ARCFOUR128.
3316
343b2385
PH
331751. Small patch to Sieve code - explicitly set From: when generating an
3318 autoreply.
3319
1c5466b9
PH
332052. Exim crashed if a remote delivery caused a very long error message to be
3321 recorded - for instance if somebody sent an entire SpamAssassin report back
3322 as a large number of 550 error lines. This bug was coincidentally fixed by
3323 increasing the size of one of Exim's internal buffers (big_buffer) that
3324 happened as part of the Exiscan merge. However, to be on the safe side, I
3325 have made the code more robust (and fixed the comments that describe what
3326 is going on).
3327
55ee9ee3
PH
332853. Now that there can be additional text after "Completed" in log lines (if
3329 the queue_time_overall log selector is set), a one-byte patch to exigrep
3330 was needed to allow it to recognize "Completed" as not the last thing in
3331 the line.
3332
d38f8232
PH
333354. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3334 patch that reportedly fixes this has been added. I am not expert enough to
3335 create a test for it. This is what the patch creator wrote:
3336
3337 "I found a little strange behaviour of ldap code when working with
3338 Windows 2003 AD Domain, where users was placed in more than one
3339 Organization Units. When I tried to give exim partial DN, the exit code
3340 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3341 But simultaneously result of request was absolutely normal ldap result,
3342 so I produce this patch..."
3343
3295e65b
PH
3344 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3345 REFERENCE, so I have modified the code to exclude the patch when that macro
3346 is not defined.
3347
7102e136
PH
334855. Some experimental protocols are using DNS PTR records for new purposes. The
3349 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3350 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3351 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
335456. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
3355
c2bcbe20
PH
335657. Double the size of the debug message buffer (to 2048) so that more of very
3357 long debug lines gets shown.
3358
18ce445d
PH
335958. The exicyclog utility now does better if the number of log files to keep
3360 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3361
1f5b4c3d
PH
336259. Two changes related to the smtp_active_hostname option:
3363
3364 (1) $smtp_active_hostname is now available as a variable.
3365 (2) The default for smtp_banner uses $smtp_active_hostname instead
3366 of $primary_hostname.
3367
b975ba52
PH
336860. The host_aton() function is supposed to be passed a string that is known
3369 to be a valid IP address. However, in the case of IPv6 addresses, it was
3370 not checking this. This is a hostage to fortune. Exim now panics and dies
3371 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3372 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3373 components; fortuitously, this particular loophole had already been fixed
3374 by change 4.50/55 above.
3375
3376 If there are any other similar loopholes, the new check in host_aton()
3377 itself should stop them being exploited. The report I received stated that
3378 data on the command line could provoke the exploit when Exim was running as
3379 exim, but did not sa
