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).

159PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
160 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
161 gnutls_require_mac & gnutls_require_protocols (no longer supported).

182PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
183
81f91683
PP
184PP/31 %D in printf continues to cause issues (-Wformat=security), so for
185 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
186 As part of this, removing so much warning spew let me fix some minor
187 real issues in debug logging.
188
5779e6aa
PP
189PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
190 assignment on my part. Fixed.
191
3375e053
PP
192PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
193 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
194 Janne Snabb (who went above and beyond: thank you).
195
196PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
197 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
198 relatively easy to get wrong. Should also expose TLS library linkage
199 problems.

b87a6e0e
PP
205 GNU libc to support some of the 64-bit stuff, should not lead to
206 conflicts. Defined before os.h is pulled in, so if a given platform
207 needs to override this, it can.
208
16880d1a
PP
209PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
210 protection layer was required, which is not implemented.

PP
213PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
214 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
215 tls_dhparam take prime identifiers. Also unbreak combination of
216 OpenSSL+DH_params+TLSSNI.

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

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

893MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
894 conversion specification without a maximum field width, thereby enabling
895 a rogue spamd server to cause a buffer overflow. While nobody in their
896 right mind would setup Exim to query an untrusted spamd server, an
897 attacker that gains access to a server running spamd could potentially
898 exploit this vulnerability to run arbitrary code as the Exim user.

MH
903MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
904 a directory entry by the name of the lookup key. Previously, if a
905 symlink pointed to a non-existing file or a file in a directory that
906 Exim lacked permissions to read, a lookup for a key matching that
907 symlink would fail. Now it is enough that a matching directory entry
908 exists, symlink or not. (Bugzilla 503.)

1091PH/29 SMTP synchronization checks are implemented when a command is read -
1092 there is a check that no more input is waiting when there shouldn't be

1094 some time before the response is written. In this time, more input might
1095 arrive, invalidly. So now there are extra checks after an ACL has run for
1096 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1097 pipelining has not been advertised.

1112 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1113 was a macro that became an assignment, so it seemed to work. This has

PH
1171 the response to the final '.' that terminates a message, but only in the
1172 case where the client has not sent further data following the '.'
1173 (unfortunately, this is allowed). However, in many cases there won't be
1174 any further data because there won't be any more messages to send. A call
1175 to select() can be used: if it shows that the input is "ready", there is
1176 either input waiting, or the socket has been closed. An attempt to read
1177 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1178 would have sent an OK response which the client would never have see.

1186Exim version 4.66
1187-----------------
1188
1189PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1190 fixed by 4.65/MH/01 (is this a record?) are fixed:
1191
1192 (i) An empty string was always treated as zero by the numeric comparison
1193 operators. This behaviour has been restored.
1194
1195 (ii) It is documented that the numeric comparison operators always treat
1196 their arguments as decimal numbers. This was broken in that numbers
1197 starting with 0 were being interpreted as octal.
1198
1199 While fixing these problems I realized that there was another issue that
1200 hadn't been noticed. Values of message_size_limit (both the global option
1201 and the transport option) were treated as octal if they started with 0.
1202 The documentation was vague. These values are now always treated as
1203 decimal, and I will make that clear in the documentation.

1213MH/01 Don't check that the operands of numeric comparison operators are
1214 integers when their expansion is in "skipping" mode (fixes bug
1215 introduced by 4.64-PH/07).

PH
1217PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1218 child addresses, Exim now panics and dies. Previously, because the count
1219 is held in a short int, deliveries were likely to be lost. As such a
1220 large number of recipients for a single message is ridiculous
1221 (performance will be very, very poor), I have chosen to impose a limit
1222 rather than extend the field.

TK
1228TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1229 leftover -K file (the existence of which was triggered by #402).
1230 While we were at it, introduced process PID as part of the -K
1231 filename. This should rule out race conditions when creating
1232 these files.
1233
1234TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1235 processing considerably. Previous code took too long for large mails,
1236 triggering a timeout which in turn triggers #401.
1237
1238TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1239 in the DK code in transports.c. sendfile() is not really portable,
1240 hence the _LINUX specificness.

1241
1242TF/01 In the add_headers option to the mail command in an Exim filter,
1243 there was a bug that Exim would claim a syntax error in any
1244 header after the first one which had an odd number of characters
1245 in the field name.
1246
2b1c6e3a
PH
1247PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1248 callout verification, Exim cached a "reject" for the entire domain. This
1249 is correct for most verifications, but it is not correct for a recipient
1250 verification with use_sender or use_postmaster set, because in that case
1251 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1252 case of MAIL FROM:<> rejection from other early rejections (e.g.
1253 rejection of HELO). When verifying a recipient using a non-null MAIL
1254 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1255 Whatever the result of the callout, the value of the domain cache is
1256 left unchanged (for any other kind of callout, getting as far as trying
1257 RCPT means that the domain itself is ok).

1262PH/03 On Solaris, an unexpectedly close socket (dropped connection) can
1263 manifest itself as EPIPE rather than ECONNECT. When tidying away a

1265 ignores EPIPE as well.

PH
1291PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1292 hostname. This is wrong, because it relates to the incoming message (and
1293 probably the interface on which it is arriving) and not to the outgoing
1294 callout (which could be using a different interface). This has been
1295 changed to use the value of the helo_data option from the smtp transport
1296 instead - this is what is used when a message is actually being sent. If
1297 there is no remote transport (possible with a router that sets up host
1298 addresses), $smtp_active_hostname is used.
6ea85e9a 1299
14aa5a05 1300PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1301 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1302 (a) The code assumed that strncpy() returns a negative number on buffer
1303 overflow, which isn't the case. Replaced with Exim's string_format()
1304 function.
1305 (b) There were several signed/unsigned issues. I just did the minimum
1306 hacking in of casts. There is scope for a larger refactoring.
1307 (c) The code used strcasecmp() which is not a standard C function.
1308 Replaced with Exim's strcmpic() function.
1309 (d) The code set only $1; it now sets $auth1 as well.
1310 (e) A simple test gave the error "authentication client didn't specify
1311 service in request". It would seem that Dovecot has changed its
1312 interface. Fortunately there's a specification; I followed it and
1313 changed what the client sends and it appears to be working now.

PH
1318PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1319 address A is aliased to B and C, where B exists and C does not. Without
1320 -v the output is "A verified" because verification stops after a
1321 successful redirection if more than one address is generated. However,
1322 with -v the child addresses are also verified. Exim was outputting "A
1323 failed to verify" and then showing the successful verification for C,
1324 with its parentage. It now outputs "B failed to verify", showing B's
1325 parentage before showing the successful verification of C.

PH
1327PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1328 look up a TXT record in a specific list after matching in a combined
1329 list.
1330
322050c2
PH
1331PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1332 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1333 they consult the DNS. I had assumed they would set it the way they
1334 wanted; and indeed my experiments on Linux seem to show that in some
1335 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1336 To be on the safe side, however, I have now made the interface to
1337 host_find_byname() similar to host_find_bydns(), with an argument
1338 containing the DNS resolver options. The host_find_byname() function now
1339 sets these options at its start, just as host_find_bydns() does. The smtp
1340 transport options dns_qualify_single and dns_search_parents are passed to
1341 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1342 of host_find_byname() use the default settings of RES_DEFNAMES
1343 (qualify_single) but not RES_DNSRCH (search_parents).
1344
08955dd3
PH
1345PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1346 spool_read_header() do less string testing, by means of a preliminary
1347 switch on the second character of optional "-foo" lines. (This is
1348 overdue, caused by the large number of possibilities that now exist.
1349 Originally there were few.) While I was there, I also converted the
1350 str(n)cmp tests so they don't re-test the leading "-" and the first
1351 character, in the hope this might squeeze out yet more improvement.
1352

PH
1353PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1354 flag allowing group syntax was set by the header_syntax check but not
1355 turned off, possible causing trouble later; (2) The flag was not being
1356 set at all for the header_verify test, causing "group"-style headers to
1357 be rejected. I have now set it in this case, and also caused header_
1358 verify to ignore an empty address taken from a group. While doing this, I
1359 came across some other cases where the code for allowing group syntax
1360 while scanning a header line wasn't quite right (mostly, not resetting
1361 the flag correctly in the right place). These bugs could have caused
1362 trouble for malformed header lines. I hope it is now all correct.
1363
602e59e5
PH
1364PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1365 with the "reply" argument non-NULL. The code, however (which originally
1366 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1367 but it didn't always do it. This confused somebody who was copying the
1368 code for some other use. I have removed all the tests.
1369
411ef850
PH
1370PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1371 feature that was used to support insecure browsers during the U.S. crypto
1372 embargo. It requires special client support, and Exim is probably the
1373 only MTA that supported it -- and would never use it because real RSA is
1374 always available. This code has been removed, because it had the bad
1375 effect of slowing Exim down by computing (never used) parameters for the
1376 RSA_EXPORT functionality.
1377
7befa435
PH
1378PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1379 authenticator to fail if there's a tab character in the incoming data
1380 (there should never be unless someone is messing about, as it's supposed
1381 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1382 if the connection is using TLS or if the remote IP is the same as the
1383 local IP, and the "valid-client-cert option" if a client certificate has
1384 been verified.
1385
48da4259 1386PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

PH
1415
1416PH/30 Exim was sometimes attempting to deliver messages that had suffered
1417 address errors (4xx response to RCPT) over the same connection as other
1418 messages routed to the same hosts. Such deliveries are always "forced",
1419 so retry times are not inspected. This resulted in far too many retries
1420 for the affected addresses. The effect occurred only when there were more
1421 hosts than the hosts_max_try setting in the smtp transport when it had
1422 the 4xx errors. Those hosts that it had tried were not added to the list
1423 of hosts for which the message was waiting, so if all were tried, there
1424 was no problem. Two fixes have been applied:
1425
1426 (i) If there are any address or message errors in an SMTP delivery, none
1427 of the hosts (tried or untried) are now added to the list of hosts
1428 for which the message is waiting, so the message should not be a
1429 candidate for sending over the same connection that was used for a
1430 successful delivery of some other message. This seems entirely
1431 reasonable: after all the message is NOT "waiting for some host".
1432 This is so "obvious" that I'm not sure why it wasn't done
1433 previously. Hope I haven't missed anything, but it can't do any
1434 harm, as the worst effect is to miss an optimization.
1435
1436 (ii) If, despite (i), such a delivery is accidentally attempted, the
1437 routing retry time is respected, so at least it doesn't keep
1438 hammering the server.

PH
1449PH/34 The spec says: "With one important exception, whenever a domain list is

1452
520de300
PH
1453PH/35 The error "getsockname() failed: connection reset by peer" was being
1454 written to the panic log as well as the main log, but it isn't really
1455 panic-worthy as it just means the connection died rather early on. I have
1456 removed the panic log writing for the ECONNRESET error when getsockname()
1457 fails.
1458
48c7f9e2
PH
1459PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1460 runs only) independently of the message's sender address. This meant
1461 that, if the 4xx error was in fact related to the sender, a different
1462 message to the same recipient with a different sender could confuse
1463 things. In particualar, this can happen when sending to a greylisting
1464 server, but other circumstances could also provoke similar problems.
1465 I have changed the default so that the retry time for these errors is now
1466 based a combination of the sender and recipient addresses. This change
1467 can be overridden by setting address_retry_include_sender=false in the
1468 smtp transport.

PH
1470PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the

1473 same for both kinds of LMTP.

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

1780PH/01 The code for finding all the local interface addresses on a FreeBSD
1781 system running IPv6 was broken. This may well have applied to all BSD
1782 systems, as well as to others that have similar system calls. The broken
1783 code found IPv4 interfaces correctly, but gave incorrect values for the
1784 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1785 that it would not match correctly against @[] and not recognize the IPv6
1786 addresses as local.

1828 generate an autoreply, and therefore failed to obtain an address for the
1829 autoreply, Exim could try to deliver to a non-existent relative file
1830 name, causing unrelated and misleading errors. What now happens is that

1850 changes:
1851
1852 (a) Failures to set uid/gid, the current directory, or a process leader
1853 in a subprocess such as that created by queryprogram now generate
1854 suitable debugging ouput when -d is set.
1855

1858 the subprocess without attempting to change uid/gid.

1863PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1864 additional section of a DNS packet that returns MX or SRV records.
1865 Instead, it always explicitly searches for A/AAAA records. This avoids
1866 major problems that occur when a DNS server includes only records of one
1867 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1868 fixed another bug: if SRV records were looked up and the corresponding
1869 address records were *not* found in the additional section, the port
1870 values from the SRV records were lost.

1872PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
1880PH/19 When calculating a retry time, Exim used to measure the "time since
1881 failure" by looking at the "first failed" field in the retry record. Now
1882 it does not use this if it is later than than the arrival time of the
1883 message. Instead it uses the arrival time. This makes for better
1884 behaviour in cases where some deliveries succeed, thus re-setting the
1885 "first failed" field. An example is a quota failure for a huge message
1886 when small messages continue to be delivered. Without this change, the
1887 "time since failure" will always be short, possible causing more frequent
1888 delivery attempts for the huge message than are intended.

PH
1985PH/42 The content-scanning code uses fopen() to create files in which to put
1986 message data. Previously it was not paying any attention to the mode of
1987 the files. Exim runs with umask(0) because the rest of the code creates
1988 files with open(), and sets the required mode explicitly. Thus, these
1989 files were ending up world-writeable. This was not a big issue, because,
1990 being within the spool directory, they were not world-accessible. I have
1991 created a function called modefopen, which takes an additional mode
1992 argument. It sets umask(777), creates the file, chmods it to the required
1993 mode, then resets the umask. All the relevant calls to fopen() in the
1994 content scanning code have been changed to use this function.

2029PH/52 Two bugs concerned with error handling when the smtp transport is

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

2115PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2116 function verify_get_ident() calls ip_connect() to connect a socket, but
2117 if the "connect()" function timed out, ip_connect() used to close the
2118 socket. However, verify_get_ident() also closes the socket later, and in
2119 between Exim writes to the log, which may get opened at this point. When
2120 the socket was closed in ip_connect(), the log could get the same file
2121 descriptor number as the socket. This naturally causes chaos. The fix is
2122 not to close the socket in ip_connect(); the socket should be closed by
2123 the function that creates it. There was only one place in the code where
2124 this was missing, in the iplookup router, which I don't think anybody now
2125 uses, but I've fixed it anyway.

2148
2149 (2) Treat a missing third argument of ${prvscheck as if it were an empty

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

2182 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2183 not being looked up in the rDNS to get a host name, Exim was showing the
2184 IP address twice in Received: lines, even though the IP addresses were
2185 identical. For example:
2186
2187 Received: from [1.2.3.4] (helo=[1.2.3.4])
2188
2189 However, if the real host name was known, it was omitting the HELO data
2190 if it matched the actual IP address. This has been tidied up so that it
2191 doesn't show the same IP address twice.

2222 in the messages that it generates (bounce messages and others, such as
2223 warnings). In the case of bounce messages for non-SMTP mesages, there was
2224 also a typo: it was using "Auto_submitted" (underscore instead of
2225 hyphen). Since every message generated by Exim is necessarily in response
2226 to another message, thes have all been changed to:
2227
2228 Auto-Submitted: auto-replied
2229
2230 in accordance with these statements in the RFC:
2231
2232 The auto-replied keyword:

2283 addresses acquired from the DNS when checking that the found name did
2284 have the original IP as one of its addresses. Since any found IPv6
2285 addresses are likely to be in abbreviated form, the comparison could
2286 fail. Luckily, there already exists a function for doing the comparison
2287 by converting both addresses to binary, so now that is used instead of
2288 the text comparison.

2373 only if the host matched helo_try_verify_hosts, which caused the
2374 verification to occur when the EHLO/HELO command was issued. The ACL just
2375 tested the remembered result. Now, if a previous verification attempt has
2376 not happened, "verify = helo" does it there and then.

2586 with the definition in sysexits.h (which is #included earlier).
2587 Fortunately, Exim does not actually use EX_OK. The code used to try to
2588 preserve the sysexits.h value, by assumimg that macro definitions were
2589 scanned for macro replacements. I have been disabused of this notion,

2595 This seems wrong - if the receiver was accepting one byte at a time it
2596 would take for ever. The timeout is now adjusted when this happens. It
2597 doesn't have to be particularly precise.

2772 spool, instead of being failed because of the mua_wrapper setting. This
2773 is now fixed, and I tidied up some of the mua_wrapper messages at the
2774 same time.

2805
2806PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2807 that changes the way the GnuTLS parameters are stored in the cache file.
2808 The new format can be generated externally. For backward compatibility,
2809 if the data in the cache doesn't make sense, Exim assumes it has read an
2810 old-format file, and it generates new data and writes a new file. This
2811 means that you can't go back to an older release without removing the
2812 file.
2813
2814PH/03 A redirect router that has both "unseen" and "one_time" set does not
2815 work if there are any delivery delays because "one_time" forces the
2816 parent to be marked "delivered", so its unseen clone is never tried
2817 again. For this reason, Exim now forbids the simultaneous setting of
2818 these two options.
2819
2820PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2821 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2822 entry if you want to know the details. The fix, however, neglected to
2823 consider the case when local delivery batching is involved. The test for
2824 "previously delivered" was not happening when checking to see if an
2825 address could be batched with a previous (undelivered) one; under
2826 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2827 address.

2829PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2831
2832PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2833 header_syntax) but Exim was just ignoring anything given after a slash.
2834 In particular, this caused confusion with an attempt to use "verify =
2835 reverse_host_lookup/defer_ok". An error is now given when options are
2836 supplied for verify items that do not have them. (Maybe reverse_host_
2837 lookup should have a defer_ok option, but that's a different point.)
2838
2839PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2889PH/19 When an Exim process that is running as root has to create an Exim log
2890 file, it does so in a subprocess that runs as exim:exim so as to get the
2891 ownership right at creation (otherwise, other Exim processes might see
2892 the file with the wrong ownership). There was no test for failure of this
2893 fork() call, which would lead to the process getting stuck as it waited
2894 for a non-existent subprocess. Forks do occasionally fail when resources
2895 run out. I reviewed all the other calls to fork(); they all seem to check
2896 for failure.

2901 the result was a log entry for a synchronization error with an empty
2902 string after "input=" when read() returned zero. If read() returned -1
2903 (an event I could not check), uninitialized data bytes were printed.

PH
2915PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2916 hadn't been configured. The fix is from Juergen Kreileder, who
2917 understands it better than I do:
2918
2919 "Here's what I see happening with three configured cyrus_sasl
2920 authenticators configured (plain, login, cram-md5):
2921
2922 On startup auth_cyrus_sasl_init() gets called for each of these.
2923 This means three calls to sasl_listmech() without a specified mech_list.
2924 => SASL tests which mechs of all available mechs actually work
2925 => three warnings about OTP not working
2926 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2927
2928 With the patch, sasl_listmech() also gets called three times. But now
2929 SASL's mech_list option is set to the server_mech specified in the the
2930 authenticator. Or in other words, the answer from sasl_listmech()
2931 gets limited to just the mech you're testing for (which is different
2932 for each call.)
2933 => the return list contains just 'plain' or 'login', 'cram-md5' or
2934 nothing depending on the value of ob->server_mech.
2935
2936 I've just tested the patch: Authentication still works fine,
2937 unavailable mechs specified in the exim configuration are still
2938 caught, and the auth.log warnings about OTP are gone."

PH
3002PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3003 the grounds that routing the same address twice would always produce the
3004 same answer. This might have been true once, but it is certainly no
3005 longer true now. Routing a child address may depend on the previous
3006 routing that produced that child. Some complicated redirection strategies
3007 went wrong when messages had multiple recipients, and made Exim's
3008 behaviour dependent on the order in which the addresses were given.
3009
3010 I have moved the duplicate checking until after the routing is complete.
3011 Exim scans the addresses that are assigned to local and remote
3012 transports, and removes any duplicates. This means that more work will be
3013 done, as duplicates will always all be routed, but duplicates are
3014 presumably rare, so I don't expect this is of any significance.
3015
3016 For deliveries to pipes, files, and autoreplies, the duplicate checking
3017 still happens during the routing process, since they are not going to be
3018 routed further.

3062 successful delivery. Such timeouts include transport filter timeouts. For
3063 consistency with the overall process timeout, these timeouts are now
3064 treated as errors, giving rise to delivery failures by default. However,
3065 there is now a new Boolean option for the pipe transport called
3066 timeout_defer, which, if set TRUE, converts the failures into defers for
3067 both kinds of timeout. A transport filter timeout is now identified in

3077A note about Exim versions 4.44 and 4.50
3078----------------------------------------
3079
3080Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3081changes of various kinds. As a consequence, a big documentation update was
3082needed. This delayed the release for rather longer than seemed good, especially
3083in the light of a couple of (minor) security issues. Therefore, the changes
3084that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3085release. So 4.44 and 4.50 are in effect two different branches that both start
3086from 4.43.
3087
3088I have left the 4.50 change log unchanged; it contains all the changes since
30894.43. The change log for 4.44 is below; many of its items are identical to
3090those for 4.50. This seems to be the most sensible way to preserve the
3091historical information.

3120 systems. I've change it so that if it can't get 1000, it tries for 256.

3161 handles timeouts, both on the server side and network timeouts. Renamed the
3162 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).

PH
316421. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3165 It is now set to "smtps".

PH
316722. $host_address is now set to the target address during the checking of
3168 ignore_target_hosts.
3169
317023. When checking ignore_target_hosts for an ipliteral router, no host name was
3171 being passed; this would have caused $sender_host_name to have been used if
3172 matching the list had actually called for a host name (not very likely,
3173 since this list is usually IP addresses). A host name is now passed as
3174 "[x.x.x.x]".
3175
7d468ab8
PH
317624. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3177 code that specifies a non-restarting handler (typically sigaction() in
3178 modern systems) in an attempt to fix a rare and obscure crash bug.
3179
318025. Narrowed the window for a race in the daemon that could cause it to ignore
3181 SIGCHLD signals. This is not a major problem, because they are used only to
3182 wake it up if nothing else does.
3183

PH
318426. A malformed maildirsize file could cause Exim to calculate negative values
3185 for the mailbox size or file count. Odd effects could occur as a result.
3186 The maildirsize information is now recalculated if the size or filecount
3187 end up negative.
3188

PH
318927. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3190 support for a long time. Removed HAVE_SYS_VFS_H.

PH
319429. In an address list, if the pattern was not a regular expression, an empty
3195 subject address (from a bounce message) matched only if the pattern was an
3196 empty string. Non-empty patterns were not even tested. This was the wrong
3197 because it is perfectly reasonable to use an empty address as part of a
3198 database query. An empty address is now tested by patterns that are
3199 lookups. However, all the other forms of pattern expect the subject to
3200 contain a local part and a domain, and therefore, for them, an empty
3201 address still always fails if the pattern is not itself empty.
3202

PH
320330. Exim went into a mad DNS loop when attempting to do a callout where the
3204 host was specified on an smtp transport, and looking it up yielded more
3205 than one IP address.
3206
5cb8cbc6
PH
320731. Re-factored the code for checking spool and log partition space into a
3208 function that finds that data and another that does the check. The former
3209 is then used to implement four new variables: $spool_space, $log_space,
3210 $spool_inodes, and $log_inodes.
3211

PH
321232. The RFC2047 encoding function was originally intended for short strings
3213 such as real names; it was not keeping to the 75-character limit for
3214 encoded words that the RFC imposes. It now respects the limit, and
3215 generates multiple encoded words if necessary. To be on the safe side, I
3216 have increased the buffer size for the ${rfc2047: expansion operator from
3217 1024 to 2048 bytes.
3218
063b1e99
PH
321933. It is now permitted to omit both strings after an "if" condition; if the
3220 condition is true, the result is "true". As before, when the second string
3221 is omitted, a false condition yields an empty string. This makes it less
3222 cumbersome to write custom ACL and router conditions.
3223
652e1b65
PH
322434. Failure to deliver a bounce message always caused it to be frozen, even if
3225 there was an errors_to setting on the router. The errors_to setting is now
3226 respected.
3227
6f0c9a4f
PH
322835. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3229 canonical form (fully expanded) before being placed in
3230 $sender_host_address.
3231

PH
323236. The table in the code that translates DNS record types into text (T_A to
3233 "A" for instance) was missing entries for NS and CNAME. It is just possible
3234 that this could have caused confusion if both these types were looked up
3235 for the same domain, because the text type is used as part of Exim's
3236 per-process caching. But the chance of anyone hitting this buglet seems
3237 very small.
3238
7bb56e1f
PH
323937. The dnsdb lookup has been extended in a number of ways.
3240
3241 (1) There is a new type, "zns", which walks up the domain tree until it
3242 finds some nameserver records. It should be used with care.
3243
ea3bc19b
PH
3244 (2) There is a new type, "mxh", which is like "mx" except that it returns
3245 just the host names, not the priorities.
3246
3247 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3248 looked up. The behaviour when one of the lookups defers can be
3249 controlled by a keyword.
7bb56e1f 3250
ea3bc19b 3251 (4) It is now possible to specify the separator character for use when
7bb56e1f 3252 multiple records are returned.
33397d19 3253
0bcb2a0e
PH
325438. The dnslists ACL condition has been extended: it is now possible to supply
3255 a list of IP addresses and/or domains to be looked up in a particular DNS
3256 domain.

326040. When running the queue in the test harness, wait just a tad after forking a
3261 delivery process, to get repeatability of debugging output.

PH
326341. Include certificate and key file names in error message when GnuTLS fails
3264 to set them up, because the GnuTLS error message doesn't include the name
3265 of the failing file when there is a problem reading it.

327144. The "Exiscan patch" is now merged into the mainline Exim source.
3272
327345. Sometimes the final signoff response after QUIT could fail to get
3274 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3275 < 0 before doing a fflush(). This bug looks as though it goes back to the
3276 introduction of TLS in release 3.20, but "sometimes" must have been rare
3277 because the tests only now provoked it.

327946. Reset the locale to "C" after calling embedded Perl, in case it was changed
3280 (this can affect the format of dates).

PH
328247. exim_tidydb, when checking for the continued existence of a message for
3283 which it has found a message-specific retry record, was not finding
3284 messages that were in split spool directories. Consequently, it was
3285 deleting retry records that should have stayed in existence.

328748. Steve fixed some bugs in eximstats.
3288
328949. The SPA authentication driver was not abandoning authentication and moving
3290 on to the next authenticator when an expansion was forced to fail,
3291 contradicting the general specification for all authenticators. Instead it
3292 was generating a temporary error. It now behaves as specified.
3293

PH
329450. The default ordering of permitted cipher suites for GnuTLS was pessimal
3295 (the order specifies the preference for clients). The order is now AES256,
3296 AES128, 3DES, ARCFOUR128.

329851. Small patch to Sieve code - explicitly set From: when generating an

PH
330152. Exim crashed if a remote delivery caused a very long error message to be
3302 recorded - for instance if somebody sent an entire SpamAssassin report back
3303 as a large number of 550 error lines. This bug was coincidentally fixed by
3304 increasing the size of one of Exim's internal buffers (big_buffer) that
3305 happened as part of the Exiscan merge. However, to be on the safe side, I
3306 have made the code more robust (and fixed the comments that describe what
3307 is going on).
3308
55ee9ee3
PH
330953. Now that there can be additional text after "Completed" in log lines (if
3310 the queue_time_overall log selector is set), a one-byte patch to exigrep
3311 was needed to allow it to recognize "Completed" as not the last thing in
3312 the line.

PH
331454. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3315 patch that reportedly fixes this has been added. I am not expert enough to
3316 create a test for it. This is what the patch creator wrote:
3317
3318 "I found a little strange behaviour of ldap code when working with
3319 Windows 2003 AD Domain, where users was placed in more than one
3320 Organization Units. When I tried to give exim partial DN, the exit code
3321 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3322 But simultaneously result of request was absolutely normal ldap result,
3323 so I produce this patch..."
3324
3295e65b
PH
3325 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3326 REFERENCE, so I have modified the code to exclude the patch when that macro
3327 is not defined.
3328

PH
332955. Some experimental protocols are using DNS PTR records for new purposes. The
3330 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3331 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3332 leaves it alone. Component reversal etc. now happens only for IP addresses.

334058. The exicyclog utility now does better if the number of log files to keep

PH
334359. Two changes related to the smtp_active_hostname option:
3344
3345 (1) $smtp_active_hostname is now available as a variable.
3346 (2) The default for smtp_banner uses $smtp_active_hostname instead
3347 of $primary_hostname.

b975ba52
PH
334960. The host_aton() function is supposed to be passed a string that is known
3350 to be a valid IP address. However, in the case of IPv6 addresses, it was
3351 not checking this. This is a hostage to fortune. Exim now panics and dies
3352 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3353 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3354 components; fortuitously, this particular loophole had already been fixed
3355 by change 4.50/55 above.
3356
3357 If there are any other similar loopholes, the new check in host_aton()
3358 itself should stop them being exploited. The report I received stated that
3359 data on the command line could provoke the exploit when Exim was running as
3360 exim, but did not say which command line option was involved. All I could
3361 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3362 running as the user.

PH
337363. The daemon start-up calls getloadavg() while still root for those OS that
3374 need the first call to be done as root, but it missed one case: when
3375 deliver_queue_load_max is set with deliver_drop_privilege. This is
3376 necessary for the benefit of the queue runner, because there is no re-exec
3377 when deliver_drop_privilege is set.
