PP
178PP/31 %D in printf continues to cause issues (-Wformat=security), so for
179 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
180 As part of this, removing so much warning spew let me fix some minor
181 real issues in debug logging.
182
5779e6aa
PP
183PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
184 assignment on my part. Fixed.
185
3375e053
PP
186PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
187 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
188 Janne Snabb (who went above and beyond: thank you).
189
190PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
191 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
192 relatively easy to get wrong. Should also expose TLS library linkage

PP
199 GNU libc to support some of the 64-bit stuff, should not lead to

207PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built

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

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

865PH/01 Another patch from the Sieve maintainer.
866
6a3bceb1
PH
867PH/02 When an IPv6 address is converted to a string for single-key lookup
868 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
869 dots are used instead of colons so that keys in lsearch files need not
870 contain colons. This was done some time before quoting was made available
871 in lsearch files. However, iplsearch files do require colons in IPv6 keys
872 (notated using the quote facility) so as to distinguish them from IPv4
873 keys. This meant that lookups for IP addresses in host lists did not work
874 for iplsearch lookups.
875
876 This has been fixed by arranging for IPv6 addresses to be expressed with
877 colons if the lookup type is iplsearch. This is not incompatible, because
878 previously such lookups could never work.
879
880 The situation is now rather anomolous, since one *can* have colons in
881 ordinary lsearch keys. However, making the change in all cases is
882 incompatible and would probably break a number of configurations.

MH
887MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
888 conversion specification without a maximum field width, thereby enabling
889 a rogue spamd server to cause a buffer overflow. While nobody in their
890 right mind would setup Exim to query an untrusted spamd server, an
891 attacker that gains access to a server running spamd could potentially
892 exploit this vulnerability to run arbitrary code as the Exim user.

MH
897MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
898 a directory entry by the name of the lookup key. Previously, if a
899 symlink pointed to a non-existing file or a file in a directory that
900 Exim lacked permissions to read, a lookup for a key matching that
901 symlink would fail. Now it is enough that a matching directory entry
902 exists, symlink or not. (Bugzilla 503.)

PH
1085PH/29 SMTP synchronization checks are implemented when a command is read -
1086 there is a check that no more input is waiting when there shouldn't be
1087 any. However, for some commands, a delay in an ACL can mean that it is
1088 some time before the response is written. In this time, more input might
1089 arrive, invalidly. So now there are extra checks after an ACL has run for
1090 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1091 pipelining has not been advertised.

1105 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1106 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1107 was a macro that became an assignment, so it seemed to work. This has

1109 error. Exim's code has been fixed.

1147 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1165 the response to the final '.' that terminates a message, but only in the
1166 case where the client has not sent further data following the '.'
1167 (unfortunately, this is allowed). However, in many cases there won't be
1168 any further data because there won't be any more messages to send. A call
1169 to select() can be used: if it shows that the input is "ready", there is
1170 either input waiting, or the socket has been closed. An attempt to read
1171 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1172 would have sent an OK response which the client would never have see.

1187 operators. This behaviour has been restored.
1188
1189 (ii) It is documented that the numeric comparison operators always treat
1190 their arguments as decimal numbers. This was broken in that numbers
1191 starting with 0 were being interpreted as octal.
1192
1193 While fixing these problems I realized that there was another issue that
1194 hadn't been noticed. Values of message_size_limit (both the global option
1195 and the transport option) were treated as octal if they started with 0.
1196 The documentation was vague. These values are now always treated as
1197 decimal, and I will make that clear in the documentation.

1214 large number of recipients for a single message is ridiculous
1215 (performance will be very, very poor), I have chosen to impose a limit

1222TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1223 leftover -K file (the existence of which was triggered by #402).

1232TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

1239 in the field name.

2b1c6e3a
PH
1241PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1242 callout verification, Exim cached a "reject" for the entire domain. This
1243 is correct for most verifications, but it is not correct for a recipient
1244 verification with use_sender or use_postmaster set, because in that case
1245 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1246 case of MAIL FROM:<> rejection from other early rejections (e.g.
1247 rejection of HELO). When verifying a recipient using a non-null MAIL
1248 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1249 Whatever the result of the callout, the value of the domain cache is
1250 left unchanged (for any other kind of callout, getting as far as trying
1251 RCPT means that the domain itself is ok).

1285PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1287 probably the interface on which it is arriving) and not to the outgoing
1288 callout (which could be using a different interface). This has been
1289 changed to use the value of the helo_data option from the smtp transport
1290 instead - this is what is used when a message is actually being sent. If
1291 there is no remote transport (possible with a router that sets up host
1292 addresses), $smtp_active_hostname is used.

7befa435 1295 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1296 (a) The code assumed that strncpy() returns a negative number on buffer
1297 overflow, which isn't the case. Replaced with Exim's string_format()
1298 function.
1299 (b) There were several signed/unsigned issues. I just did the minimum
1300 hacking in of casts. There is scope for a larger refactoring.
1301 (c) The code used strcasecmp() which is not a standard C function.
1302 Replaced with Exim's strcmpic() function.
1303 (d) The code set only $1; it now sets $auth1 as well.
1304 (e) A simple test gave the error "authentication client didn't specify
1305 service in request". It would seem that Dovecot has changed its
1306 interface. Fortunately there's a specification; I followed it and
1307 changed what the client sends and it appears to be working now.

1313 address A is aliased to B and C, where B exists and C does not. Without
1314 -v the output is "A verified" because verification stops after a
1315 successful redirection if more than one address is generated. However,
1316 with -v the child addresses are also verified. Exim was outputting "A
1317 failed to verify" and then showing the successful verification for C,
1318 with its parentage. It now outputs "B failed to verify", showing B's
1319 parentage before showing the successful verification of C.

1324
322050c2
PH
1325PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1326 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1327 they consult the DNS. I had assumed they would set it the way they
1328 wanted; and indeed my experiments on Linux seem to show that in some
1329 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1330 To be on the safe side, however, I have now made the interface to
1331 host_find_byname() similar to host_find_bydns(), with an argument
1332 containing the DNS resolver options. The host_find_byname() function now
1333 sets these options at its start, just as host_find_bydns() does. The smtp
1334 transport options dns_qualify_single and dns_search_parents are passed to
1335 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1336 of host_find_byname() use the default settings of RES_DEFNAMES
1337 (qualify_single) but not RES_DNSRCH (search_parents).

1339PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1340 spool_read_header() do less string testing, by means of a preliminary
1341 switch on the second character of optional "-foo" lines. (This is
1342 overdue, caused by the large number of possibilities that now exist.
1343 Originally there were few.) While I was there, I also converted the
1344 str(n)cmp tests so they don't re-test the leading "-" and the first
1345 character, in the hope this might squeeze out yet more improvement.

PH
1347PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1348 flag allowing group syntax was set by the header_syntax check but not
1349 turned off, possible causing trouble later; (2) The flag was not being
1350 set at all for the header_verify test, causing "group"-style headers to
1351 be rejected. I have now set it in this case, and also caused header_
1352 verify to ignore an empty address taken from a group. While doing this, I
1353 came across some other cases where the code for allowing group syntax
1354 while scanning a header line wasn't quite right (mostly, not resetting
1355 the flag correctly in the right place). These bugs could have caused
1356 trouble for malformed header lines. I hope it is now all correct.

PH
1358PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1359 with the "reply" argument non-NULL. The code, however (which originally
1360 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1361 but it didn't always do it. This confused somebody who was copying the
1362 code for some other use. I have removed all the tests.

PH
1364PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1365 feature that was used to support insecure browsers during the U.S. crypto
1366 embargo. It requires special client support, and Exim is probably the
1367 only MTA that supported it -- and would never use it because real RSA is
1368 always available. This code has been removed, because it had the bad
1369 effect of slowing Exim down by computing (never used) parameters for the
1370 RSA_EXPORT functionality.

1373 authenticator to fail if there's a tab character in the incoming data

1375 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1376 if the connection is using TLS or if the remote IP is the same as the
1377 local IP, and the "valid-client-cert option" if a client certificate has
1378 been verified.

PH
1409
1410PH/30 Exim was sometimes attempting to deliver messages that had suffered
1411 address errors (4xx response to RCPT) over the same connection as other
1412 messages routed to the same hosts. Such deliveries are always "forced",
1413 so retry times are not inspected. This resulted in far too many retries
1414 for the affected addresses. The effect occurred only when there were more
1415 hosts than the hosts_max_try setting in the smtp transport when it had
1416 the 4xx errors. Those hosts that it had tried were not added to the list
1417 of hosts for which the message was waiting, so if all were tried, there
1418 was no problem. Two fixes have been applied:
1419
1420 (i) If there are any address or message errors in an SMTP delivery, none
1421 of the hosts (tried or untried) are now added to the list of hosts
1422 for which the message is waiting, so the message should not be a
1423 candidate for sending over the same connection that was used for a
1424 successful delivery of some other message. This seems entirely
1425 reasonable: after all the message is NOT "waiting for some host".
1426 This is so "obvious" that I'm not sure why it wasn't done
1427 previously. Hope I haven't missed anything, but it can't do any
1428 harm, as the worst effect is to miss an optimization.
1429
1430 (ii) If, despite (i), such a delivery is accidentally attempted, the
1431 routing retry time is respected, so at least it doesn't keep
1432 hammering the server.

1447PH/35 The error "getsockname() failed: connection reset by peer" was being
1448 written to the panic log as well as the main log, but it isn't really
1449 panic-worthy as it just means the connection died rather early on. I have
1450 removed the panic log writing for the ECONNRESET error when getsockname()
1451 fails.
1452
48c7f9e2
PH
1453PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1454 runs only) independently of the message's sender address. This meant
1455 that, if the 4xx error was in fact related to the sender, a different
1456 message to the same recipient with a different sender could confuse
1457 things. In particualar, this can happen when sending to a greylisting
1458 server, but other circumstances could also provoke similar problems.
1459 I have changed the default so that the retry time for these errors is now
1460 based a combination of the sender and recipient addresses. This change
1461 can be overridden by setting address_retry_include_sender=false in the
1462 smtp transport.

1730PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1732 Unfortunately, if there is a major crisis, such as a disk failure,
1733 tcp-wrappers gives "deny", whereas what one would like would be some
1734 kind of temporary error. A kludge has been added to help with this.
1735 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1736 554 error is used if errno is still zero or contains ENOENT (which occurs
1737 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1738 451 error is used.

1774PH/01 The code for finding all the local interface addresses on a FreeBSD
1775 system running IPv6 was broken. This may well have applied to all BSD
1776 systems, as well as to others that have similar system calls. The broken
1777 code found IPv4 interfaces correctly, but gave incorrect values for the
1778 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1779 that it would not match correctly against @[] and not recognize the IPv6
1780 addresses as local.

1821 syntactically invalid From: or Reply-to: line, and a filter used this to
1822 generate an autoreply, and therefore failed to obtain an address for the
1823 autoreply, Exim could try to deliver to a non-existent relative file
1824 name, causing unrelated and misleading errors. What now happens is that
1825 it logs this as a hard delivery error, but does not attempt to create a

1843 non-existent - all you got was a failure to exec. I have made two
1844 changes:
1845
1846 (a) Failures to set uid/gid, the current directory, or a process leader
1847 in a subprocess such as that created by queryprogram now generate
1848 suitable debugging ouput when -d is set.
1849
1850 (b) The queryprogram router detects when it is not running as root,
1851 outputs suitable debugging information if -d is set, and then runs
1852 the subprocess without attempting to change uid/gid.

1857PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1858 additional section of a DNS packet that returns MX or SRV records.
1859 Instead, it always explicitly searches for A/AAAA records. This avoids
1860 major problems that occur when a DNS server includes only records of one
1861 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1862 fixed another bug: if SRV records were looked up and the corresponding
1863 address records were *not* found in the additional section, the port
1864 values from the SRV records were lost.

ea49d0e1
PH
1866PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

1873
727071f8
PH
1874PH/19 When calculating a retry time, Exim used to measure the "time since
1875 failure" by looking at the "first failed" field in the retry record. Now
1876 it does not use this if it is later than than the arrival time of the
1877 message. Instead it uses the arrival time. This makes for better
1878 behaviour in cases where some deliveries succeed, thus re-setting the
1879 "first failed" field. An example is a quota failure for a huge message
1880 when small messages continue to be delivered. Without this change, the
1881 "time since failure" will always be short, possible causing more frequent
1882 delivery attempts for the huge message than are intended.

PH
1979PH/42 The content-scanning code uses fopen() to create files in which to put
1980 message data. Previously it was not paying any attention to the mode of
1981 the files. Exim runs with umask(0) because the rest of the code creates
1982 files with open(), and sets the required mode explicitly. Thus, these
1983 files were ending up world-writeable. This was not a big issue, because,
1984 being within the spool directory, they were not world-accessible. I have
1985 created a function called modefopen, which takes an additional mode
1986 argument. It sets umask(777), creates the file, chmods it to the required
1987 mode, then resets the umask. All the relevant calls to fopen() in the
1988 content scanning code have been changed to use this function.

1998 default, the authentication attempt is cancelled if an invalid string is
1999 received. Setting client_ignore_invalid_base64 true ignores these errors.
2000 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2001 they are received. Thus, the responses can be made to depend on the

2023PH/52 Two bugs concerned with error handling when the smtp transport is
2024 used in LMTP mode:
2025
2026 (i) Exim was not creating retry information for temporary errors given
2027 for individual recipients after the DATA command when the smtp transport
2028 was used in LMTP mode. This meant that they could be retried too
2029 frequently, and not timed out correctly.
2030
2031 (ii) Exim was setting the flag that allows error details to be returned
2032 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2033 recipients that were returned after the DATA command.
2034
2035PH/53 This is related to PH/52, but is more general: for any failing address,
2036 when detailed error information was permitted to be returned to the
2037 sender, but the error was temporary, then after the final timeout, only
2038 "retry timeout exceeded" was returned. Now it returns the full error as
2039 well as "retry timeout exceeded".

2109PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2110 function verify_get_ident() calls ip_connect() to connect a socket, but
2111 if the "connect()" function timed out, ip_connect() used to close the
2112 socket. However, verify_get_ident() also closes the socket later, and in
2113 between Exim writes to the log, which may get opened at this point. When
2114 the socket was closed in ip_connect(), the log could get the same file
2115 descriptor number as the socket. This naturally causes chaos. The fix is
2116 not to close the socket in ip_connect(); the socket should be closed by
2117 the function that creates it. There was only one place in the code where
2118 this was missing, in the iplookup router, which I don't think anybody now
2119 uses, but I've fixed it anyway.

2142
2143 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2144 string.
2145
2146 (3) Reset the variables that are obtained from the first argument of
2147 ${prvscheck and used in the second argument before leaving the code,
2148 because their memory is reclaimed, so using them afterwards may do
2149 silly things.
2150
2151 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2152 one (it's much easier than Tom thought :-).

2175PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2176 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2177 not being looked up in the rDNS to get a host name, Exim was showing the
2178 IP address twice in Received: lines, even though the IP addresses were
2179 identical. For example:
2180
2181 Received: from [1.2.3.4] (helo=[1.2.3.4])
2182
2183 However, if the real host name was known, it was omitting the HELO data
2184 if it matched the actual IP address. This has been tidied up so that it
2185 doesn't show the same IP address twice.

2211PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2213
2214 Auto-submitted: auto-generated
2215
2216 in the messages that it generates (bounce messages and others, such as
2217 warnings). In the case of bounce messages for non-SMTP mesages, there was
2218 also a typo: it was using "Auto_submitted" (underscore instead of
2219 hyphen). Since every message generated by Exim is necessarily in response
2220 to another message, thes have all been changed to:
2221
2222 Auto-Submitted: auto-replied
2223
2224 in accordance with these statements in the RFC:
2225
2226 The auto-replied keyword:
2227
2228 - SHOULD be used on messages sent in direct response to another
2229 message by an automatic process,
2230

2276 the IP address, check_host() was doing a simple string comparison with
2277 addresses acquired from the DNS when checking that the found name did
2278 have the original IP as one of its addresses. Since any found IPv6
2279 addresses are likely to be in abbreviated form, the comparison could
2280 fail. Luckily, there already exists a function for doing the comparison
2281 by converting both addresses to binary, so now that is used instead of
2282 the text comparison.

2401
2402 - Error returned from rc_read_config was caught wrongly
2403 - Username/password not passed on to radius server due to wrong length.

2405 The presumption is that some radiusclient API changes for 4.51/PH/17

2579PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2580 with the definition in sysexits.h (which is #included earlier).
2581 Fortunately, Exim does not actually use EX_OK. The code used to try to
2582 preserve the sysexits.h value, by assumimg that macro definitions were
2583 scanned for macro replacements. I have been disabused of this notion,
2584 so now the code just undefines EX_OK before #including unistd.h.

2586PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2587 in the smtp transport. When a block could not be written in a single
2588 write() function, the timeout was being re-applied to each part-write.
2589 This seems wrong - if the receiver was accepting one byte at a time it
2590 would take for ever. The timeout is now adjusted when this happens. It
2591 doesn't have to be particularly precise.

2667 case the guess is not the same as the compiled default, so the script
2668 suddenly stopped working when I started to use syslog. The patch checks
2669 to see if log_file_path is "". If so, it attempts to read it from exim

2727PH/27 If a dnslookup or manualroute router is set with verify=only, it need not

2763PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
2764 the use of a port name that isn't defined in /etc/services) occurred, the
2765 message was deferred as in a normal delivery, and thus remained on the
2766 spool, instead of being failed because of the mua_wrapper setting. This
2767 is now fixed, and I tidied up some of the mua_wrapper messages at the
2768 same time.

2799
2800PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2801 that changes the way the GnuTLS parameters are stored in the cache file.
2802 The new format can be generated externally. For backward compatibility,
2803 if the data in the cache doesn't make sense, Exim assumes it has read an
2804 old-format file, and it generates new data and writes a new file. This
2805 means that you can't go back to an older release without removing the
2806 file.
2807
2808PH/03 A redirect router that has both "unseen" and "one_time" set does not
2809 work if there are any delivery delays because "one_time" forces the
2810 parent to be marked "delivered", so its unseen clone is never tried
2811 again. For this reason, Exim now forbids the simultaneous setting of
2812 these two options.
2813
2814PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2815 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2816 entry if you want to know the details. The fix, however, neglected to
2817 consider the case when local delivery batching is involved. The test for
2818 "previously delivered" was not happening when checking to see if an
2819 address could be batched with a previous (undelivered) one; under
2820 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2821 address.

2823PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2825
2826PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2827 header_syntax) but Exim was just ignoring anything given after a slash.
2828 In particular, this caused confusion with an attempt to use "verify =
2829 reverse_host_lookup/defer_ok". An error is now given when options are
2830 supplied for verify items that do not have them. (Maybe reverse_host_
2831 lookup should have a defer_ok option, but that's a different point.)
2832
2833PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2884 file, it does so in a subprocess that runs as exim:exim so as to get the
2885 ownership right at creation (otherwise, other Exim processes might see
2886 the file with the wrong ownership). There was no test for failure of this
2887 fork() call, which would lead to the process getting stuck as it waited
2888 for a non-existent subprocess. Forks do occasionally fail when resources
2889 run out. I reviewed all the other calls to fork(); they all seem to check
2890 for failure.

2895 the result was a log entry for a synchronization error with an empty
2896 string after "input=" when read() returned zero. If read() returned -1
2897 (an event I could not check), uninitialized data bytes were printed.

PH
2909PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2910 hadn't been configured. The fix is from Juergen Kreileder, who
2911 understands it better than I do:
2912
2913 "Here's what I see happening with three configured cyrus_sasl
2914 authenticators configured (plain, login, cram-md5):
2915
2916 On startup auth_cyrus_sasl_init() gets called for each of these.
2917 This means three calls to sasl_listmech() without a specified mech_list.
2918 => SASL tests which mechs of all available mechs actually work
2919 => three warnings about OTP not working
2920 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2921
2922 With the patch, sasl_listmech() also gets called three times. But now
2923 SASL's mech_list option is set to the server_mech specified in the the
2924 authenticator. Or in other words, the answer from sasl_listmech()
2925 gets limited to just the mech you're testing for (which is different
2926 for each call.)
2927 => the return list contains just 'plain' or 'login', 'cram-md5' or
2928 nothing depending on the value of ob->server_mech.
2929
2930 I've just tested the patch: Authentication still works fine,
2931 unavailable mechs specified in the exim configuration are still
2932 caught, and the auth.log warnings about OTP are gone."

PH
2996PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2997 the grounds that routing the same address twice would always produce the
2998 same answer. This might have been true once, but it is certainly no
2999 longer true now. Routing a child address may depend on the previous
3000 routing that produced that child. Some complicated redirection strategies
3001 went wrong when messages had multiple recipients, and made Exim's
3002 behaviour dependent on the order in which the addresses were given.
3003
3004 I have moved the duplicate checking until after the routing is complete.
3005 Exim scans the addresses that are assigned to local and remote
3006 transports, and removes any duplicates. This means that more work will be
3007 done, as duplicates will always all be routed, but duplicates are
3008 presumably rare, so I don't expect this is of any significance.
3009
3010 For deliveries to pipes, files, and autoreplies, the duplicate checking
3011 still happens during the routing process, since they are not going to be
3012 routed further.

3057 consistency with the overall process timeout, these timeouts are now
3058 treated as errors, giving rise to delivery failures by default. However,
3059 there is now a new Boolean option for the pipe transport called
3060 timeout_defer, which, if set TRUE, converts the failures into defers for
3061 both kinds of timeout. A transport filter timeout is now identified in

3071A note about Exim versions 4.44 and 4.50
3072----------------------------------------
3073
3074Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3075changes of various kinds. As a consequence, a big documentation update was
3076needed. This delayed the release for rather longer than seemed good, especially
3077in the light of a couple of (minor) security issues. Therefore, the changes
3078that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3079release. So 4.44 and 4.50 are in effect two different branches that both start
3080from 4.43.
3081
3082I have left the 4.50 change log unchanged; it contains all the changes since
30834.43. The change log for 4.44 is below; many of its items are identical to
3084those for 4.50. This seems to be the most sensible way to preserve the
3085historical information.

3107 filters, and the commands run by the lmtp and pipe transports.

3114 systems. I've change it so that if it can't get 1000, it tries for 256.

316423. When checking ignore_target_hosts for an ipliteral router, no host name was
3165 being passed; this would have caused $sender_host_name to have been used if
3166 matching the list had actually called for a host name (not very likely,
3167 since this list is usually IP addresses). A host name is now passed as
3168 "[x.x.x.x]".
3169

PH
317024. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3171 code that specifies a non-restarting handler (typically sigaction() in
3172 modern systems) in an attempt to fix a rare and obscure crash bug.
3173
317425. Narrowed the window for a race in the daemon that could cause it to ignore
3175 SIGCHLD signals. This is not a major problem, because they are used only to
3176 wake it up if nothing else does.
3177
62c0818f
PH
317826. A malformed maildirsize file could cause Exim to calculate negative values
3179 for the mailbox size or file count. Odd effects could occur as a result.
3180 The maildirsize information is now recalculated if the size or filecount
3181 end up negative.
3182
26034054
PH
318327. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3184 support for a long time. Removed HAVE_SYS_VFS_H.

318628. Installed the latest version of exipick from John Jetmore.

PH
318829. In an address list, if the pattern was not a regular expression, an empty
3189 subject address (from a bounce message) matched only if the pattern was an
3190 empty string. Non-empty patterns were not even tested. This was the wrong
3191 because it is perfectly reasonable to use an empty address as part of a
3192 database query. An empty address is now tested by patterns that are
3193 lookups. However, all the other forms of pattern expect the subject to
3194 contain a local part and a domain, and therefore, for them, an empty
3195 address still always fails if the pattern is not itself empty.
3196
d8ef3577
PH
319730. Exim went into a mad DNS loop when attempting to do a callout where the
3198 host was specified on an smtp transport, and looking it up yielded more
3199 than one IP address.
3200
5cb8cbc6
PH
320131. Re-factored the code for checking spool and log partition space into a
3202 function that finds that data and another that does the check. The former
3203 is then used to implement four new variables: $spool_space, $log_space,
3204 $spool_inodes, and $log_inodes.
3205
14702f5b
PH
320632. The RFC2047 encoding function was originally intended for short strings
3207 such as real names; it was not keeping to the 75-character limit for
3208 encoded words that the RFC imposes. It now respects the limit, and
3209 generates multiple encoded words if necessary. To be on the safe side, I
3210 have increased the buffer size for the ${rfc2047: expansion operator from
3211 1024 to 2048 bytes.
3212
063b1e99
PH
321333. It is now permitted to omit both strings after an "if" condition; if the
3214 condition is true, the result is "true". As before, when the second string
3215 is omitted, a false condition yields an empty string. This makes it less
3216 cumbersome to write custom ACL and router conditions.
3217
652e1b65
PH
321834. Failure to deliver a bounce message always caused it to be frozen, even if
3219 there was an errors_to setting on the router. The errors_to setting is now
3220 respected.
3221
6f0c9a4f
PH
322235. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3223 canonical form (fully expanded) before being placed in
3224 $sender_host_address.
3225
33397d19
PH
322636. The table in the code that translates DNS record types into text (T_A to
3227 "A" for instance) was missing entries for NS and CNAME. It is just possible
3228 that this could have caused confusion if both these types were looked up
3229 for the same domain, because the text type is used as part of Exim's
3230 per-process caching. But the chance of anyone hitting this buglet seems
3231 very small.
3232
7bb56e1f
PH
323337. The dnsdb lookup has been extended in a number of ways.
3234
3235 (1) There is a new type, "zns", which walks up the domain tree until it
3236 finds some nameserver records. It should be used with care.
3237
ea3bc19b
PH
3238 (2) There is a new type, "mxh", which is like "mx" except that it returns
3239 just the host names, not the priorities.
3240
3241 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3242 looked up. The behaviour when one of the lookups defers can be
3243 controlled by a keyword.
7bb56e1f 3244
ea3bc19b 3245 (4) It is now possible to specify the separator character for use when
7bb56e1f 3246 multiple records are returned.
33397d19 3247
0bcb2a0e
PH
324838. The dnslists ACL condition has been extended: it is now possible to supply
3249 a list of IP addresses and/or domains to be looked up in a particular DNS
3250 domain.

325239. Added log_selector=+queue_time_overall.

PH
325440. When running the queue in the test harness, wait just a tad after forking a
3255 delivery process, to get repeatability of debugging output.

de365ded
PH
325741. Include certificate and key file names in error message when GnuTLS fails
3258 to set them up, because the GnuTLS error message doesn't include the name
3259 of the failing file when there is a problem reading it.

PH
326544. The "Exiscan patch" is now merged into the mainline Exim source.
3266
326745. Sometimes the final signoff response after QUIT could fail to get
3268 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3269 < 0 before doing a fflush(). This bug looks as though it goes back to the
3270 introduction of TLS in release 3.20, but "sometimes" must have been rare
3271 because the tests only now provoked it.
3272

PH
327346. Reset the locale to "C" after calling embedded Perl, in case it was changed
3274 (this can affect the format of dates).
3275

PH
327647. exim_tidydb, when checking for the continued existence of a message for
3277 which it has found a message-specific retry record, was not finding
3278 messages that were in split spool directories. Consequently, it was
3279 deleting retry records that should have stayed in existence.

PH
328148. Steve fixed some bugs in eximstats.
3282
328349. The SPA authentication driver was not abandoning authentication and moving
3284 on to the next authenticator when an expansion was forced to fail,
3285 contradicting the general specification for all authenticators. Instead it
3286 was generating a temporary error. It now behaves as specified.
3287

PH
328850. The default ordering of permitted cipher suites for GnuTLS was pessimal
3289 (the order specifies the preference for clients). The order is now AES256,
3290 AES128, 3DES, ARCFOUR128.

PH
329251. Small patch to Sieve code - explicitly set From: when generating an
3293 autoreply.
3294

PH
329552. Exim crashed if a remote delivery caused a very long error message to be
3296 recorded - for instance if somebody sent an entire SpamAssassin report back
3297 as a large number of 550 error lines. This bug was coincidentally fixed by
3298 increasing the size of one of Exim's internal buffers (big_buffer) that
3299 happened as part of the Exiscan merge. However, to be on the safe side, I
3300 have made the code more robust (and fixed the comments that describe what
3301 is going on).
3302
55ee9ee3
PH
330353. Now that there can be additional text after "Completed" in log lines (if
3304 the queue_time_overall log selector is set), a one-byte patch to exigrep
3305 was needed to allow it to recognize "Completed" as not the last thing in
3306 the line.
3307

PH
330854. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3309 patch that reportedly fixes this has been added. I am not expert enough to
3310 create a test for it. This is what the patch creator wrote:
3311
3312 "I found a little strange behaviour of ldap code when working with
3313 Windows 2003 AD Domain, where users was placed in more than one
3314 Organization Units. When I tried to give exim partial DN, the exit code
3315 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3316 But simultaneously result of request was absolutely normal ldap result,
3317 so I produce this patch..."
3318
3295e65b
PH
3319 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3320 REFERENCE, so I have modified the code to exclude the patch when that macro
3321 is not defined.
3322

PH
332355. Some experimental protocols are using DNS PTR records for new purposes. The
3324 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3325 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3326 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
333458. The exicyclog utility now does better if the number of log files to keep

PH
333759. Two changes related to the smtp_active_hostname option:
3338
3339 (1) $smtp_active_hostname is now available as a variable.
3340 (2) The default for smtp_banner uses $smtp_active_hostname instead
3341 of $primary_hostname.
3342
b975ba52
PH
334360. The host_aton() function is supposed to be passed a string that is known
3344 to be a valid IP address. However, in the case of IPv6 addresses, it was
3345 not checking this. This is a hostage to fortune. Exim now panics and dies
3346 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3347 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3348 components; fortuitously, this particular loophole had already been fixed
3349 by change 4.50/55 above.
3350
3351 If there are any other similar loopholes, the new check in host_aton()
3352 itself should stop them being exploited. The report I received stated that
3353 data on the command line could provoke the exploit when Exim was running as
3354 exim, but did not say which command line option was involved. All I could
3355 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3356 running as the user.

335961. There was a buffer overflow vulnerability in the SPA authentication code
3360 (which came originally from the Samba project). I have added a test to the

PH
336763. The daemon start-up calls getloadavg() while still root for those OS that
3368 need the first call to be done as root, but it missed one case: when
3369 deliver_queue_load_max is set with deliver_drop_privilege. This is
3370 necessary for the benefit of the queue runner, because there is no re-exec
3371 when deliver_drop_privilege is set.
3372
86b8287f
PH
337364. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3374 This has been fixed.
3375
60dc5e56
PH
337665. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3377 was in use, was not putting the data itself into the right store pool;
3378 consequently, it could be overwritten for a subsequent message in the same
3379 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3380 the caching.)
3381

PH
338266. Added hosts_max_try_hardlimit to the smtp transport, default 50.
