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).

123PP/14 TLS fixes for OpenSSL: support TLS 1.1 & 1.2; new "openssl_options"
124 values; set SSL_MODE_AUTO_RETRY so that OpenSSL will retry a read
125 or write after TLS renegotiation, which otherwise led to messages
126 "Got SSL error 2".

153PP/19 DNS resolver init changes for NetBSD compatibility. (Risk of breakage
154 on less well tested platforms). Obviates NetBSD pkgsrc patch-ac.

198
81f91683
PP
199PP/31 %D in printf continues to cause issues (-Wformat=security), so for
200 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
201 As part of this, removing so much warning spew let me fix some minor
202 real issues in debug logging.
203
5779e6aa
PP
204PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
205 assignment on my part. Fixed.
206
3375e053
PP
207PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
208 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
209 Janne Snabb (who went above and beyond: thank you).
210
211PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
212 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
213 relatively easy to get wrong. Should also expose TLS library linkage
214 problems.

PP
220 GNU libc to support some of the 64-bit stuff, should not lead to
221 conflicts. Defined before os.h is pulled in, so if a given platform

PP
228PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built

TF
250TF/03 Make the exiwhat support code safe for signals. Previously Exim might
251 lock up or crash if it happened to be inside a call to libc when it
252 got a SIGUSR1 from exiwhat.
253
254 The SIGUSR1 handler appends the current process status to the process
255 log which is later printed by exiwhat. It used to use the general
256 purpose logging code to do this, but several functions it calls are
257 not safe for signals.
258
259 The new output code in the SIGUSR1 handler is specific to the process
260 log, and simple enough that it's easy to inspect for signal safety.
261 Removing some special cases also simplifies the general logging code.
262 Removing the spurious timestamps from the process log simplifies
263 exiwhat.
264
c99ce5c9
TF
265TF/04 Improved ratelimit ACL condition.
266
267 The /noupdate option has been deprecated in favour of /readonly which
268 has clearer semantics. The /leaky, /strict, and /readonly update modes
269 are mutually exclusive. The update mode is no longer included in the
270 database key; it just determines when the database is updated. (This
271 means that when you upgrde Exim will forget old rate measurements.)
272
273 Exim now checks that the per_* options are used with an update mode that
274 makes sense for the current ACL. For example, when Exim is processing a
275 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
276 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
277 must specify per_mail/readonly. If you omit the update mode it defaults to
278 /leaky where that makes sense (as before) or /readonly where required.
279
280 The /noupdate option is now undocumented but still supported for
281 backwards compatibility. It is equivalent to /readonly except that in
282 ACLs where /readonly is required you may specify /leaky/noupdate or
283 /strict/noupdate which are treated the same as /readonly.
284
285 A useful new feature is the /count= option. This is a generalization
286 of the per_byte option, so that you can measure the throughput of other
287 aggregate values. For example, the per_byte option is now equivalent
288 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
289
290 The per_rcpt option has been generalized using the /count= mechanism
291 (though it's more complicated than the per_byte equivalence). When it is
292 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
293 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
294 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
295 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
296 Note that using per_rcpt with a non-readonly update mode in more than
297 one ACL will cause the recipients to be double-counted. (The per_mail
298 and per_byte options don't have this problem.)
299
300 The handling of very low rates has changed slightly. If the computed rate
301 is less than the event's count (usually one) then this event is the first
302 after a long gap. In this case the rate is set to the same as this event's
303 count, so that the first message of a spam run is counted properly.
304
305 The major new feature is a mechanism for counting the rate of unique
306 events. The new per_addr option counts the number of different
307 recipients that someone has sent messages to in the last time period. It
308 behaves like per_rcpt if all the recipient addresses are different, but
309 duplicate recipient addresses do not increase the measured rate. Like
310 the /count= option this is a general mechanism, so the per_addr option
311 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
312 example, measure the rate that a client uses different sender addresses
313 with the options per_mail/unique=$sender_address. There are further
314 details in the main documentation.

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

886PH/01 Another patch from the Sieve maintainer.
887
6a3bceb1
PH
888PH/02 When an IPv6 address is converted to a string for single-key lookup
889 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
890 dots are used instead of colons so that keys in lsearch files need not
891 contain colons. This was done some time before quoting was made available
892 in lsearch files. However, iplsearch files do require colons in IPv6 keys
893 (notated using the quote facility) so as to distinguish them from IPv4
894 keys. This meant that lookups for IP addresses in host lists did not work
895 for iplsearch lookups.
896
897 This has been fixed by arranging for IPv6 addresses to be expressed with
898 colons if the lookup type is iplsearch. This is not incompatible, because
899 previously such lookups could never work.
900
901 The situation is now rather anomolous, since one *can* have colons in
902 ordinary lsearch keys. However, making the change in all cases is
903 incompatible and would probably break a number of configurations.

MH
908MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
909 conversion specification without a maximum field width, thereby enabling
910 a rogue spamd server to cause a buffer overflow. While nobody in their
911 right mind would setup Exim to query an untrusted spamd server, an
912 attacker that gains access to a server running spamd could potentially
913 exploit this vulnerability to run arbitrary code as the Exim user.

MH
918MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
919 a directory entry by the name of the lookup key. Previously, if a
920 symlink pointed to a non-existing file or a file in a directory that
921 Exim lacked permissions to read, a lookup for a key matching that
922 symlink would fail. Now it is enough that a matching directory entry
923 exists, symlink or not. (Bugzilla 503.)

1106PH/29 SMTP synchronization checks are implemented when a command is read -
1107 there is a check that no more input is waiting when there shouldn't be

1109 some time before the response is written. In this time, more input might
1110 arrive, invalidly. So now there are extra checks after an ACL has run for
1111 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1112 pipelining has not been advertised.

1127 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1128 was a macro that became an assignment, so it seemed to work. This has

58eb016e 1185PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1186 the response to the final '.' that terminates a message, but only in the
1187 case where the client has not sent further data following the '.'
1188 (unfortunately, this is allowed). However, in many cases there won't be
1189 any further data because there won't be any more messages to send. A call
1190 to select() can be used: if it shows that the input is "ready", there is
1191 either input waiting, or the socket has been closed. An attempt to read
1192 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1193 would have sent an OK response which the client would never have see.

1201Exim version 4.66
1202-----------------
1203
1204PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1205 fixed by 4.65/MH/01 (is this a record?) are fixed:
1206
1207 (i) An empty string was always treated as zero by the numeric comparison
1208 operators. This behaviour has been restored.
1209
1210 (ii) It is documented that the numeric comparison operators always treat
1211 their arguments as decimal numbers. This was broken in that numbers
1212 starting with 0 were being interpreted as octal.
1213
1214 While fixing these problems I realized that there was another issue that
1215 hadn't been noticed. Values of message_size_limit (both the global option
1216 and the transport option) were treated as octal if they started with 0.
1217 The documentation was vague. These values are now always treated as
1218 decimal, and I will make that clear in the documentation.

PH
1232PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1233 child addresses, Exim now panics and dies. Previously, because the count
1234 is held in a short int, deliveries were likely to be lost. As such a
1235 large number of recipients for a single message is ridiculous
1236 (performance will be very, very poor), I have chosen to impose a limit
1237 rather than extend the field.

1243TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1244 leftover -K file (the existence of which was triggered by #402).
1245 While we were at it, introduced process PID as part of the -K
1246 filename. This should rule out race conditions when creating
1247 these files.

1249TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1250 processing considerably. Previous code took too long for large mails,
1251 triggering a timeout which in turn triggers #401.
1252
1253TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1254 in the DK code in transports.c. sendfile() is not really portable,

1257TF/01 In the add_headers option to the mail command in an Exim filter,

1260 in the field name.

PH
1262PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1263 callout verification, Exim cached a "reject" for the entire domain. This
1264 is correct for most verifications, but it is not correct for a recipient
1265 verification with use_sender or use_postmaster set, because in that case
1266 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1267 case of MAIL FROM:<> rejection from other early rejections (e.g.
1268 rejection of HELO). When verifying a recipient using a non-null MAIL
1269 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1270 Whatever the result of the callout, the value of the domain cache is
1271 left unchanged (for any other kind of callout, getting as far as trying
1272 RCPT means that the domain itself is ok).

1306PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1307 hostname. This is wrong, because it relates to the incoming message (and
1308 probably the interface on which it is arriving) and not to the outgoing
1309 callout (which could be using a different interface). This has been
1310 changed to use the value of the helo_data option from the smtp transport
1311 instead - this is what is used when a message is actually being sent. If
1312 there is no remote transport (possible with a router that sets up host
1313 addresses), $smtp_active_hostname is used.

14aa5a05 1315PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1316 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1317 (a) The code assumed that strncpy() returns a negative number on buffer
1318 overflow, which isn't the case. Replaced with Exim's string_format()
1319 function.
1320 (b) There were several signed/unsigned issues. I just did the minimum
1321 hacking in of casts. There is scope for a larger refactoring.
1322 (c) The code used strcasecmp() which is not a standard C function.
1323 Replaced with Exim's strcmpic() function.
1324 (d) The code set only $1; it now sets $auth1 as well.
1325 (e) A simple test gave the error "authentication client didn't specify
1326 service in request". It would seem that Dovecot has changed its
1327 interface. Fortunately there's a specification; I followed it and
1328 changed what the client sends and it appears to be working now.

1333PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1334 address A is aliased to B and C, where B exists and C does not. Without
1335 -v the output is "A verified" because verification stops after a
1336 successful redirection if more than one address is generated. However,
1337 with -v the child addresses are also verified. Exim was outputting "A
1338 failed to verify" and then showing the successful verification for C,
1339 with its parentage. It now outputs "B failed to verify", showing B's
1340 parentage before showing the successful verification of C.

1343 look up a TXT record in a specific list after matching in a combined

1345
322050c2
PH
1346PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1347 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1348 they consult the DNS. I had assumed they would set it the way they
1349 wanted; and indeed my experiments on Linux seem to show that in some
1350 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1351 To be on the safe side, however, I have now made the interface to
1352 host_find_byname() similar to host_find_bydns(), with an argument
1353 containing the DNS resolver options. The host_find_byname() function now
1354 sets these options at its start, just as host_find_bydns() does. The smtp
1355 transport options dns_qualify_single and dns_search_parents are passed to
1356 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1357 of host_find_byname() use the default settings of RES_DEFNAMES
1358 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1360PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1361 spool_read_header() do less string testing, by means of a preliminary
1362 switch on the second character of optional "-foo" lines. (This is
1363 overdue, caused by the large number of possibilities that now exist.
1364 Originally there were few.) While I was there, I also converted the
1365 str(n)cmp tests so they don't re-test the leading "-" and the first
1366 character, in the hope this might squeeze out yet more improvement.

PH
1368PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1369 flag allowing group syntax was set by the header_syntax check but not
1370 turned off, possible causing trouble later; (2) The flag was not being
1371 set at all for the header_verify test, causing "group"-style headers to
1372 be rejected. I have now set it in this case, and also caused header_
1373 verify to ignore an empty address taken from a group. While doing this, I
1374 came across some other cases where the code for allowing group syntax
1375 while scanning a header line wasn't quite right (mostly, not resetting
1376 the flag correctly in the right place). These bugs could have caused
1377 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1379PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1380 with the "reply" argument non-NULL. The code, however (which originally
1381 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1382 but it didn't always do it. This confused somebody who was copying the
1383 code for some other use. I have removed all the tests.

PH
1385PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1386 feature that was used to support insecure browsers during the U.S. crypto
1387 embargo. It requires special client support, and Exim is probably the
1388 only MTA that supported it -- and would never use it because real RSA is
1389 always available. This code has been removed, because it had the bad
1390 effect of slowing Exim down by computing (never used) parameters for the
1391 RSA_EXPORT functionality.

7befa435
PH
1393PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1394 authenticator to fail if there's a tab character in the incoming data
1395 (there should never be unless someone is messing about, as it's supposed
1396 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1397 if the connection is using TLS or if the remote IP is the same as the
1398 local IP, and the "valid-client-cert option" if a client certificate has
1399 been verified.

PH
1430
1431PH/30 Exim was sometimes attempting to deliver messages that had suffered
1432 address errors (4xx response to RCPT) over the same connection as other
1433 messages routed to the same hosts. Such deliveries are always "forced",
1434 so retry times are not inspected. This resulted in far too many retries
1435 for the affected addresses. The effect occurred only when there were more
1436 hosts than the hosts_max_try setting in the smtp transport when it had
1437 the 4xx errors. Those hosts that it had tried were not added to the list
1438 of hosts for which the message was waiting, so if all were tried, there
1439 was no problem. Two fixes have been applied:
1440
1441 (i) If there are any address or message errors in an SMTP delivery, none
1442 of the hosts (tried or untried) are now added to the list of hosts
1443 for which the message is waiting, so the message should not be a
1444 candidate for sending over the same connection that was used for a
1445 successful delivery of some other message. This seems entirely
1446 reasonable: after all the message is NOT "waiting for some host".
1447 This is so "obvious" that I'm not sure why it wasn't done
1448 previously. Hope I haven't missed anything, but it can't do any
1449 harm, as the worst effect is to miss an optimization.
1450
1451 (ii) If, despite (i), such a delivery is accidentally attempted, the
1452 routing retry time is respected, so at least it doesn't keep
1453 hammering the server.

PH
1468PH/35 The error "getsockname() failed: connection reset by peer" was being
1469 written to the panic log as well as the main log, but it isn't really
1470 panic-worthy as it just means the connection died rather early on. I have
1471 removed the panic log writing for the ECONNRESET error when getsockname()
1472 fails.
1473
48c7f9e2
PH
1474PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1475 runs only) independently of the message's sender address. This meant
1476 that, if the 4xx error was in fact related to the sender, a different
1477 message to the same recipient with a different sender could confuse
1478 things. In particualar, this can happen when sending to a greylisting
1479 server, but other circumstances could also provoke similar problems.
1480 I have changed the default so that the retry time for these errors is now
1481 based a combination of the sender and recipient addresses. This change
1482 can be overridden by setting address_retry_include_sender=false in the
1483 smtp transport.

1751PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1753 Unfortunately, if there is a major crisis, such as a disk failure,
1754 tcp-wrappers gives "deny", whereas what one would like would be some
1755 kind of temporary error. A kludge has been added to help with this.
1756 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1757 554 error is used if errno is still zero or contains ENOENT (which occurs
1758 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1759 451 error is used.

1798 code found IPv4 interfaces correctly, but gave incorrect values for the
1799 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1800 that it would not match correctly against @[] and not recognize the IPv6
1801 addresses as local.

1844 autoreply, Exim could try to deliver to a non-existent relative file

1869 suitable debugging ouput when -d is set.

1880 Instead, it always explicitly searches for A/AAAA records. This avoids
1881 major problems that occur when a DNS server includes only records of one
1882 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1883 fixed another bug: if SRV records were looked up and the corresponding
1884 address records were *not* found in the additional section, the port
1885 values from the SRV records were lost.

1887PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1895PH/19 When calculating a retry time, Exim used to measure the "time since
1896 failure" by looking at the "first failed" field in the retry record. Now
1897 it does not use this if it is later than than the arrival time of the
1898 message. Instead it uses the arrival time. This makes for better
1899 behaviour in cases where some deliveries succeed, thus re-setting the
1900 "first failed" field. An example is a quota failure for a huge message
1901 when small messages continue to be delivered. Without this change, the
1902 "time since failure" will always be short, possible causing more frequent
1903 delivery attempts for the huge message than are intended.

PH
2000PH/42 The content-scanning code uses fopen() to create files in which to put
2001 message data. Previously it was not paying any attention to the mode of
2002 the files. Exim runs with umask(0) because the rest of the code creates
2003 files with open(), and sets the required mode explicitly. Thus, these
2004 files were ending up world-writeable. This was not a big issue, because,
2005 being within the spool directory, they were not world-accessible. I have
2006 created a function called modefopen, which takes an additional mode
2007 argument. It sets umask(777), creates the file, chmods it to the required
2008 mode, then resets the umask. All the relevant calls to fopen() in the
2009 content scanning code have been changed to use this function.

2044PH/52 Two bugs concerned with error handling when the smtp transport is
2045 used in LMTP mode:
2046
2047 (i) Exim was not creating retry information for temporary errors given
2048 for individual recipients after the DATA command when the smtp transport
2049 was used in LMTP mode. This meant that they could be retried too
2050 frequently, and not timed out correctly.
2051
2052 (ii) Exim was setting the flag that allows error details to be returned
2053 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2054 recipients that were returned after the DATA command.
2055
2056PH/53 This is related to PH/52, but is more general: for any failing address,
2057 when detailed error information was permitted to be returned to the
2058 sender, but the error was temporary, then after the final timeout, only
2059 "retry timeout exceeded" was returned. Now it returns the full error as

2130PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2131 function verify_get_ident() calls ip_connect() to connect a socket, but
2132 if the "connect()" function timed out, ip_connect() used to close the
2133 socket. However, verify_get_ident() also closes the socket later, and in
2134 between Exim writes to the log, which may get opened at this point. When
2135 the socket was closed in ip_connect(), the log could get the same file
2136 descriptor number as the socket. This naturally causes chaos. The fix is
2137 not to close the socket in ip_connect(); the socket should be closed by
2138 the function that creates it. There was only one place in the code where
2139 this was missing, in the iplookup router, which I don't think anybody now
2140 uses, but I've fixed it anyway.

2164 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2166
2167 (3) Reset the variables that are obtained from the first argument of
2168 ${prvscheck and used in the second argument before leaving the code,
2169 because their memory is reclaimed, so using them afterwards may do
2170 silly things.
2171
2172 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2173 one (it's much easier than Tom thought :-).

2197 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2198 not being looked up in the rDNS to get a host name, Exim was showing the
2199 IP address twice in Received: lines, even though the IP addresses were
2200 identical. For example:
2201
2202 Received: from [1.2.3.4] (helo=[1.2.3.4])
2203
2204 However, if the real host name was known, it was omitting the HELO data
2205 if it matched the actual IP address. This has been tidied up so that it
2206 doesn't show the same IP address twice.

2238 warnings). In the case of bounce messages for non-SMTP mesages, there was
2239 also a typo: it was using "Auto_submitted" (underscore instead of

2241 to another message, thes have all been changed to:

2298 addresses acquired from the DNS when checking that the found name did
2299 have the original IP as one of its addresses. Since any found IPv6
2300 addresses are likely to be in abbreviated form, the comparison could
2301 fail. Luckily, there already exists a function for doing the comparison
2302 by converting both addresses to binary, so now that is used instead of
2303 the text comparison.

2601 with the definition in sysexits.h (which is #included earlier).
2602 Fortunately, Exim does not actually use EX_OK. The code used to try to
2603 preserve the sysexits.h value, by assumimg that macro definitions were
2604 scanned for macro replacements. I have been disabused of this notion,
2605 so now the code just undefines EX_OK before #including unistd.h.

2610 This seems wrong - if the receiver was accepting one byte at a time it
2611 would take for ever. The timeout is now adjusted when this happens. It
2612 doesn't have to be particularly precise.

2772 data, a new version was generated, as expected. It was only the case of a
2773 non-existent file that was broken.

2820
2821PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2822 that changes the way the GnuTLS parameters are stored in the cache file.
2823 The new format can be generated externally. For backward compatibility,
2824 if the data in the cache doesn't make sense, Exim assumes it has read an
2825 old-format file, and it generates new data and writes a new file. This
2826 means that you can't go back to an older release without removing the
2827 file.
2828
2829PH/03 A redirect router that has both "unseen" and "one_time" set does not
2830 work if there are any delivery delays because "one_time" forces the
2831 parent to be marked "delivered", so its unseen clone is never tried
2832 again. For this reason, Exim now forbids the simultaneous setting of
2833 these two options.

2835PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2836 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2837 entry if you want to know the details. The fix, however, neglected to
2838 consider the case when local delivery batching is involved. The test for
2839 "previously delivered" was not happening when checking to see if an
2840 address could be batched with a previous (undelivered) one; under
2841 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2842 address.

2847PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2848 header_syntax) but Exim was just ignoring anything given after a slash.
2849 In particular, this caused confusion with an attempt to use "verify =
2850 reverse_host_lookup/defer_ok". An error is now given when options are
2851 supplied for verify items that do not have them. (Maybe reverse_host_
2852 lookup should have a defer_ok option, but that's a different point.)

2854PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2907 the file with the wrong ownership). There was no test for failure of this
2908 fork() call, which would lead to the process getting stuck as it waited
2909 for a non-existent subprocess. Forks do occasionally fail when resources

2917 string after "input=" when read() returned zero. If read() returned -1

2930PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2931 hadn't been configured. The fix is from Juergen Kreileder, who
2932 understands it better than I do:
2933
2934 "Here's what I see happening with three configured cyrus_sasl
2935 authenticators configured (plain, login, cram-md5):
2936
2937 On startup auth_cyrus_sasl_init() gets called for each of these.
2938 This means three calls to sasl_listmech() without a specified mech_list.
2939 => SASL tests which mechs of all available mechs actually work
2940 => three warnings about OTP not working
2941 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2942
2943 With the patch, sasl_listmech() also gets called three times. But now
2944 SASL's mech_list option is set to the server_mech specified in the the
2945 authenticator. Or in other words, the answer from sasl_listmech()
2946 gets limited to just the mech you're testing for (which is different
2947 for each call.)
2948 => the return list contains just 'plain' or 'login', 'cram-md5' or
2949 nothing depending on the value of ob->server_mech.
2950
2951 I've just tested the patch: Authentication still works fine,

PH
3017PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3018 the grounds that routing the same address twice would always produce the
3019 same answer. This might have been true once, but it is certainly no
3020 longer true now. Routing a child address may depend on the previous
3021 routing that produced that child. Some complicated redirection strategies
3022 went wrong when messages had multiple recipients, and made Exim's
3023 behaviour dependent on the order in which the addresses were given.
3024
3025 I have moved the duplicate checking until after the routing is complete.
3026 Exim scans the addresses that are assigned to local and remote
3027 transports, and removes any duplicates. This means that more work will be
3028 done, as duplicates will always all be routed, but duplicates are
3029 presumably rare, so I don't expect this is of any significance.
3030
3031 For deliveries to pipes, files, and autoreplies, the duplicate checking
3032 still happens during the routing process, since they are not going to be
3033 routed further.

3078 consistency with the overall process timeout, these timeouts are now

3080 there is now a new Boolean option for the pipe transport called

3092A note about Exim versions 4.44 and 4.50
3093----------------------------------------
3094
3095Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3096changes of various kinds. As a consequence, a big documentation update was
3097needed. This delayed the release for rather longer than seemed good, especially
3098in the light of a couple of (minor) security issues. Therefore, the changes
3099that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3100release. So 4.44 and 4.50 are in effect two different branches that both start
3101from 4.43.
3102
3103I have left the 4.50 change log unchanged; it contains all the changes since
31044.43. The change log for 4.44 is below; many of its items are identical to
3105those for 4.50. This seems to be the most sensible way to preserve the
3106historical information.

PH
315914. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
3160

PH
316115. Added a new option "connect=<time>" to callout options, to set a different
3162 connection timeout.
3163
926e1192
PH
316416. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3165 was its contents. (It was OK if the option was not defined at all.)
3166

PH
316717. A "Completed" log line is now written for messages that are removed from
3168 the spool by the -Mrm option.
3169

PH
317018. New variables $sender_verify_failure and $recipient_verify_failure contain
3171 information about exactly what failed.

PH
317319. Added -dd to debug only the daemon process.
3174
7c7ad977
PH
317520. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3176 handles timeouts, both on the server side and network timeouts. Renamed the
3177 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
3178
981756db
PH
317921. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3180 It is now set to "smtps".
3181
d4eb88df
PH
318222. $host_address is now set to the target address during the checking of
3183 ignore_target_hosts.
3184
318523. When checking ignore_target_hosts for an ipliteral router, no host name was
3186 being passed; this would have caused $sender_host_name to have been used if
3187 matching the list had actually called for a host name (not very likely,
3188 since this list is usually IP addresses). A host name is now passed as
3189 "[x.x.x.x]".
3190
7d468ab8
PH
319124. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3192 code that specifies a non-restarting handler (typically sigaction() in
3193 modern systems) in an attempt to fix a rare and obscure crash bug.
3194
319525. Narrowed the window for a race in the daemon that could cause it to ignore
3196 SIGCHLD signals. This is not a major problem, because they are used only to
3197 wake it up if nothing else does.
3198
62c0818f
PH
319926. A malformed maildirsize file could cause Exim to calculate negative values
3200 for the mailbox size or file count. Odd effects could occur as a result.
3201 The maildirsize information is now recalculated if the size or filecount
3202 end up negative.
3203
26034054
PH
320427. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3205 support for a long time. Removed HAVE_SYS_VFS_H.
3206
af66f652
PH
320728. Installed the latest version of exipick from John Jetmore.
3208
90af77f4
PH
320929. In an address list, if the pattern was not a regular expression, an empty
3210 subject address (from a bounce message) matched only if the pattern was an
3211 empty string. Non-empty patterns were not even tested. This was the wrong
3212 because it is perfectly reasonable to use an empty address as part of a
3213 database query. An empty address is now tested by patterns that are
3214 lookups. However, all the other forms of pattern expect the subject to
3215 contain a local part and a domain, and therefore, for them, an empty
3216 address still always fails if the pattern is not itself empty.
3217
d8ef3577
PH
321830. Exim went into a mad DNS loop when attempting to do a callout where the
3219 host was specified on an smtp transport, and looking it up yielded more
3220 than one IP address.
3221
5cb8cbc6
PH
322231. Re-factored the code for checking spool and log partition space into a
3223 function that finds that data and another that does the check. The former
3224 is then used to implement four new variables: $spool_space, $log_space,
3225 $spool_inodes, and $log_inodes.
3226
14702f5b
PH
322732. The RFC2047 encoding function was originally intended for short strings
3228 such as real names; it was not keeping to the 75-character limit for
3229 encoded words that the RFC imposes. It now respects the limit, and
3230 generates multiple encoded words if necessary. To be on the safe side, I
3231 have increased the buffer size for the ${rfc2047: expansion operator from
3232 1024 to 2048 bytes.
3233
063b1e99
PH
323433. It is now permitted to omit both strings after an "if" condition; if the
3235 condition is true, the result is "true". As before, when the second string
3236 is omitted, a false condition yields an empty string. This makes it less
3237 cumbersome to write custom ACL and router conditions.
3238
652e1b65
PH
323934. Failure to deliver a bounce message always caused it to be frozen, even if
3240 there was an errors_to setting on the router. The errors_to setting is now
3241 respected.
3242
6f0c9a4f
PH
324335. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3244 canonical form (fully expanded) before being placed in
3245 $sender_host_address.
3246
33397d19
PH
324736. The table in the code that translates DNS record types into text (T_A to
3248 "A" for instance) was missing entries for NS and CNAME. It is just possible
3249 that this could have caused confusion if both these types were looked up
3250 for the same domain, because the text type is used as part of Exim's
3251 per-process caching. But the chance of anyone hitting this buglet seems
3252 very small.
3253
7bb56e1f
PH
325437. The dnsdb lookup has been extended in a number of ways.
3255
3256 (1) There is a new type, "zns", which walks up the domain tree until it
3257 finds some nameserver records. It should be used with care.
3258
ea3bc19b
PH
3259 (2) There is a new type, "mxh", which is like "mx" except that it returns
3260 just the host names, not the priorities.
3261
3262 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3263 looked up. The behaviour when one of the lookups defers can be
3264 controlled by a keyword.
7bb56e1f 3265
ea3bc19b 3266 (4) It is now possible to specify the separator character for use when
7bb56e1f 3267 multiple records are returned.
33397d19 3268
0bcb2a0e
PH
326938. The dnslists ACL condition has been extended: it is now possible to supply
3270 a list of IP addresses and/or domains to be looked up in a particular DNS
3271 domain.
3272
2ac0e484
PH
327339. Added log_selector=+queue_time_overall.
3274
4e1fde53
PH
327540. When running the queue in the test harness, wait just a tad after forking a
3276 delivery process, to get repeatability of debugging output.
3277
de365ded
PH
327841. Include certificate and key file names in error message when GnuTLS fails
3279 to set them up, because the GnuTLS error message doesn't include the name
3280 of the failing file when there is a problem reading it.
3281
f05da2e8
PH
328242. Allow both -bf and -bF in the same test run.

328443. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3285

PH
328644. The "Exiscan patch" is now merged into the mainline Exim source.
3287
328845. Sometimes the final signoff response after QUIT could fail to get
3289 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3290 < 0 before doing a fflush(). This bug looks as though it goes back to the
3291 introduction of TLS in release 3.20, but "sometimes" must have been rare
3292 because the tests only now provoked it.
3293
a444213a
PH
329446. Reset the locale to "C" after calling embedded Perl, in case it was changed
3295 (this can affect the format of dates).
3296
0ec020ea
PH
329747. exim_tidydb, when checking for the continued existence of a message for
3298 which it has found a message-specific retry record, was not finding
3299 messages that were in split spool directories. Consequently, it was
3300 deleting retry records that should have stayed in existence.
3301
b1206957
PH
330248. Steve fixed some bugs in eximstats.
3303
330449. The SPA authentication driver was not abandoning authentication and moving
3305 on to the next authenticator when an expansion was forced to fail,
3306 contradicting the general specification for all authenticators. Instead it
3307 was generating a temporary error. It now behaves as specified.
3308
26dd5a95
PH
330950. The default ordering of permitted cipher suites for GnuTLS was pessimal
3310 (the order specifies the preference for clients). The order is now AES256,
3311 AES128, 3DES, ARCFOUR128.
3312
343b2385
PH
331351. Small patch to Sieve code - explicitly set From: when generating an
3314 autoreply.
3315
1c5466b9
PH
331652. Exim crashed if a remote delivery caused a very long error message to be
3317 recorded - for instance if somebody sent an entire SpamAssassin report back
3318 as a large number of 550 error lines. This bug was coincidentally fixed by
3319 increasing the size of one of Exim's internal buffers (big_buffer) that
3320 happened as part of the Exiscan merge. However, to be on the safe side, I
3321 have made the code more robust (and fixed the comments that describe what
3322 is going on).
3323
55ee9ee3
PH
332453. Now that there can be additional text after "Completed" in log lines (if
3325 the queue_time_overall log selector is set), a one-byte patch to exigrep
3326 was needed to allow it to recognize "Completed" as not the last thing in
3327 the line.
3328
d38f8232
PH
332954. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3330 patch that reportedly fixes this has been added. I am not expert enough to
3331 create a test for it. This is what the patch creator wrote:
3332
3333 "I found a little strange behaviour of ldap code when working with
3334 Windows 2003 AD Domain, where users was placed in more than one
3335 Organization Units. When I tried to give exim partial DN, the exit code
3336 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3337 But simultaneously result of request was absolutely normal ldap result,
3338 so I produce this patch..."
3339
3295e65b
PH
3340 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3341 REFERENCE, so I have modified the code to exclude the patch when that macro
3342 is not defined.
3343
7102e136
PH
334455. Some experimental protocols are using DNS PTR records for new purposes. The
3345 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3346 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3347 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
335257. Double the size of the debug message buffer (to 2048) so that more of very
3353 long debug lines gets shown.
3354
18ce445d
PH
335558. The exicyclog utility now does better if the number of log files to keep
3356 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3357
1f5b4c3d
PH
335859. Two changes related to the smtp_active_hostname option:
3359
3360 (1) $smtp_active_hostname is now available as a variable.
3361 (2) The default for smtp_banner uses $smtp_active_hostname instead
3362 of $primary_hostname.
3363
b975ba52
PH
336460. The host_aton() function is supposed to be passed a string that is known
3365 to be a valid IP address. However, in the case of IPv6 addresses, it was
3366 not checking this. This is a hostage to fortune. Exim now panics and dies
3367 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3368 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3369 components; fortuitously, this particular loophole had already been fixed
3370 by change 4.50/55 above.
3371
3372 If there are any other similar loopholes, the new check in host_aton()
3373 itself should stop them being exploited. The report I received stated that
3374 data on the command line could provoke the exploit when Exim was running as
3375 exim, but did not say which command line option was involved. All I could
3376 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3377 running as the user.
