TF
80TF/03 Make the exiwhat support code safe for signals. Previously Exim might
81 lock up or crash if it happened to be inside a call to libc when it
82 got a SIGUSR1 from exiwhat.
83
84 The SIGUSR1 handler appends the current process status to the process
85 log which is later printed by exiwhat. It used to use the general
86 purpose logging code to do this, but several functions it calls are
87 not safe for signals.
88
89 The new output code in the SIGUSR1 handler is specific to the process
90 log, and simple enough that it's easy to inspect for signal safety.
91 Removing some special cases also simplifies the general logging code.
92 Removing the spurious timestamps from the process log simplifies
93 exiwhat.
94
c99ce5c9
TF
95TF/04 Improved ratelimit ACL condition.
96
97 The /noupdate option has been deprecated in favour of /readonly which
98 has clearer semantics. The /leaky, /strict, and /readonly update modes
99 are mutually exclusive. The update mode is no longer included in the
100 database key; it just determines when the database is updated. (This
101 means that when you upgrde Exim will forget old rate measurements.)
102
103 Exim now checks that the per_* options are used with an update mode that
104 makes sense for the current ACL. For example, when Exim is processing a
105 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
106 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
107 must specify per_mail/readonly. If you omit the update mode it defaults to
108 /leaky where that makes sense (as before) or /readonly where required.
109
110 The /noupdate option is now undocumented but still supported for
111 backwards compatibility. It is equivalent to /readonly except that in
112 ACLs where /readonly is required you may specify /leaky/noupdate or
113 /strict/noupdate which are treated the same as /readonly.
114
115 A useful new feature is the /count= option. This is a generalization
116 of the per_byte option, so that you can measure the throughput of other
117 aggregate values. For example, the per_byte option is now equivalent
118 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
119
120 The per_rcpt option has been generalized using the /count= mechanism
121 (though it's more complicated than the per_byte equivalence). When it is
122 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
123 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
124 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
125 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
126 Note that using per_rcpt with a non-readonly update mode in more than
127 one ACL will cause the recipients to be double-counted. (The per_mail
128 and per_byte options don't have this problem.)
129
130 The handling of very low rates has changed slightly. If the computed rate
131 is less than the event's count (usually one) then this event is the first
132 after a long gap. In this case the rate is set to the same as this event's
133 count, so that the first message of a spam run is counted properly.
134
135 The major new feature is a mechanism for counting the rate of unique
136 events. The new per_addr option counts the number of different
137 recipients that someone has sent messages to in the last time period. It
138 behaves like per_rcpt if all the recipient addresses are different, but
139 duplicate recipient addresses do not increase the measured rate. Like
140 the /count= option this is a general mechanism, so the per_addr option
141 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
142 example, measure the rate that a client uses different sender addresses
143 with the options per_mail/unique=$sender_address. There are further
144 details in the main documentation.

716PH/01 Another patch from the Sieve maintainer.
717
6a3bceb1
PH
718PH/02 When an IPv6 address is converted to a string for single-key lookup
719 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
720 dots are used instead of colons so that keys in lsearch files need not
721 contain colons. This was done some time before quoting was made available
722 in lsearch files. However, iplsearch files do require colons in IPv6 keys
723 (notated using the quote facility) so as to distinguish them from IPv4
724 keys. This meant that lookups for IP addresses in host lists did not work
725 for iplsearch lookups.
726
727 This has been fixed by arranging for IPv6 addresses to be expressed with
728 colons if the lookup type is iplsearch. This is not incompatible, because
729 previously such lookups could never work.
730
731 The situation is now rather anomolous, since one *can* have colons in
732 ordinary lsearch keys. However, making the change in all cases is
733 incompatible and would probably break a number of configurations.

738MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
739 conversion specification without a maximum field width, thereby enabling
740 a rogue spamd server to cause a buffer overflow. While nobody in their
741 right mind would setup Exim to query an untrusted spamd server, an
742 attacker that gains access to a server running spamd could potentially
743 exploit this vulnerability to run arbitrary code as the Exim user.

MH
748MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
749 a directory entry by the name of the lookup key. Previously, if a
750 symlink pointed to a non-existing file or a file in a directory that
751 Exim lacked permissions to read, a lookup for a key matching that
752 symlink would fail. Now it is enough that a matching directory entry
753 exists, symlink or not. (Bugzilla 503.)

936PH/29 SMTP synchronization checks are implemented when a command is read -
937 there is a check that no more input is waiting when there shouldn't be
938 any. However, for some commands, a delay in an ACL can mean that it is
939 some time before the response is written. In this time, more input might
940 arrive, invalidly. So now there are extra checks after an ACL has run for
941 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
942 pipelining has not been advertised.

PH
1016 the response to the final '.' that terminates a message, but only in the
1017 case where the client has not sent further data following the '.'
1018 (unfortunately, this is allowed). However, in many cases there won't be
1019 any further data because there won't be any more messages to send. A call
1020 to select() can be used: if it shows that the input is "ready", there is
1021 either input waiting, or the socket has been closed. An attempt to read
1022 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1023 would have sent an OK response which the client would never have see.

1034PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1035 fixed by 4.65/MH/01 (is this a record?) are fixed:
1036
1037 (i) An empty string was always treated as zero by the numeric comparison
1038 operators. This behaviour has been restored.
1039
1040 (ii) It is documented that the numeric comparison operators always treat
1041 their arguments as decimal numbers. This was broken in that numbers
1042 starting with 0 were being interpreted as octal.
1043
1044 While fixing these problems I realized that there was another issue that
1045 hadn't been noticed. Values of message_size_limit (both the global option
1046 and the transport option) were treated as octal if they started with 0.
1047 The documentation was vague. These values are now always treated as
1048 decimal, and I will make that clear in the documentation.

1064 is held in a short int, deliveries were likely to be lost. As such a
1065 large number of recipients for a single message is ridiculous
1066 (performance will be very, very poor), I have chosen to impose a limit
1067 rather than extend the field.

2b1c6e3a
PH
1092PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1093 callout verification, Exim cached a "reject" for the entire domain. This
1094 is correct for most verifications, but it is not correct for a recipient
1095 verification with use_sender or use_postmaster set, because in that case
1096 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1097 case of MAIL FROM:<> rejection from other early rejections (e.g.
1098 rejection of HELO). When verifying a recipient using a non-null MAIL
1099 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1100 Whatever the result of the callout, the value of the domain cache is
1101 left unchanged (for any other kind of callout, getting as far as trying
1102 RCPT means that the domain itself is ok).

1136PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1138 probably the interface on which it is arriving) and not to the outgoing
1139 callout (which could be using a different interface). This has been
1140 changed to use the value of the helo_data option from the smtp transport
1141 instead - this is what is used when a message is actually being sent. If
1142 there is no remote transport (possible with a router that sets up host
1143 addresses), $smtp_active_hostname is used.

7befa435 1146 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1147 (a) The code assumed that strncpy() returns a negative number on buffer
1148 overflow, which isn't the case. Replaced with Exim's string_format()
1149 function.
1150 (b) There were several signed/unsigned issues. I just did the minimum
1151 hacking in of casts. There is scope for a larger refactoring.
1152 (c) The code used strcasecmp() which is not a standard C function.
1153 Replaced with Exim's strcmpic() function.
1154 (d) The code set only $1; it now sets $auth1 as well.
1155 (e) A simple test gave the error "authentication client didn't specify
1156 service in request". It would seem that Dovecot has changed its
1157 interface. Fortunately there's a specification; I followed it and
1158 changed what the client sends and it appears to be working now.

1164 address A is aliased to B and C, where B exists and C does not. Without
1165 -v the output is "A verified" because verification stops after a
1166 successful redirection if more than one address is generated. However,
1167 with -v the child addresses are also verified. Exim was outputting "A
1168 failed to verify" and then showing the successful verification for C,
1169 with its parentage. It now outputs "B failed to verify", showing B's
1170 parentage before showing the successful verification of C.

1175
322050c2
PH
1176PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1177 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1178 they consult the DNS. I had assumed they would set it the way they
1179 wanted; and indeed my experiments on Linux seem to show that in some
1180 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1181 To be on the safe side, however, I have now made the interface to
1182 host_find_byname() similar to host_find_bydns(), with an argument
1183 containing the DNS resolver options. The host_find_byname() function now
1184 sets these options at its start, just as host_find_bydns() does. The smtp
1185 transport options dns_qualify_single and dns_search_parents are passed to
1186 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1187 of host_find_byname() use the default settings of RES_DEFNAMES
1188 (qualify_single) but not RES_DNSRCH (search_parents).

1193 overdue, caused by the large number of possibilities that now exist.
1194 Originally there were few.) While I was there, I also converted the
1195 str(n)cmp tests so they don't re-test the leading "-" and the first
1196 character, in the hope this might squeeze out yet more improvement.

1199 flag allowing group syntax was set by the header_syntax check but not
1200 turned off, possible causing trouble later; (2) The flag was not being
1201 set at all for the header_verify test, causing "group"-style headers to
1202 be rejected. I have now set it in this case, and also caused header_
1203 verify to ignore an empty address taken from a group. While doing this, I
1204 came across some other cases where the code for allowing group syntax
1205 while scanning a header line wasn't quite right (mostly, not resetting
1206 the flag correctly in the right place). These bugs could have caused
1207 trouble for malformed header lines. I hope it is now all correct.

1209PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1210 with the "reply" argument non-NULL. The code, however (which originally
1211 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1212 but it didn't always do it. This confused somebody who was copying the
1213 code for some other use. I have removed all the tests.

PH
1215PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1216 feature that was used to support insecure browsers during the U.S. crypto
1217 embargo. It requires special client support, and Exim is probably the
1218 only MTA that supported it -- and would never use it because real RSA is
1219 always available. This code has been removed, because it had the bad
1220 effect of slowing Exim down by computing (never used) parameters for the
1221 RSA_EXPORT functionality.

1223PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1224 authenticator to fail if there's a tab character in the incoming data
1225 (there should never be unless someone is messing about, as it's supposed
1226 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1227 if the connection is using TLS or if the remote IP is the same as the
1228 local IP, and the "valid-client-cert option" if a client certificate has
1229 been verified.

1260
1261PH/30 Exim was sometimes attempting to deliver messages that had suffered
1262 address errors (4xx response to RCPT) over the same connection as other
1263 messages routed to the same hosts. Such deliveries are always "forced",
1264 so retry times are not inspected. This resulted in far too many retries
1265 for the affected addresses. The effect occurred only when there were more
1266 hosts than the hosts_max_try setting in the smtp transport when it had
1267 the 4xx errors. Those hosts that it had tried were not added to the list
1268 of hosts for which the message was waiting, so if all were tried, there
1269 was no problem. Two fixes have been applied:
1270
1271 (i) If there are any address or message errors in an SMTP delivery, none
1272 of the hosts (tried or untried) are now added to the list of hosts
1273 for which the message is waiting, so the message should not be a
1274 candidate for sending over the same connection that was used for a
1275 successful delivery of some other message. This seems entirely
1276 reasonable: after all the message is NOT "waiting for some host".
1277 This is so "obvious" that I'm not sure why it wasn't done
1278 previously. Hope I haven't missed anything, but it can't do any
1279 harm, as the worst effect is to miss an optimization.
1280
1281 (ii) If, despite (i), such a delivery is accidentally attempted, the
1282 routing retry time is respected, so at least it doesn't keep
1283 hammering the server.

1298PH/35 The error "getsockname() failed: connection reset by peer" was being
1299 written to the panic log as well as the main log, but it isn't really
1300 panic-worthy as it just means the connection died rather early on. I have
1301 removed the panic log writing for the ECONNRESET error when getsockname()
1302 fails.
1303
48c7f9e2
PH
1304PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1305 runs only) independently of the message's sender address. This meant
1306 that, if the 4xx error was in fact related to the sender, a different
1307 message to the same recipient with a different sender could confuse
1308 things. In particualar, this can happen when sending to a greylisting
1309 server, but other circumstances could also provoke similar problems.
1310 I have changed the default so that the retry time for these errors is now
1311 based a combination of the sender and recipient addresses. This change
1312 can be overridden by setting address_retry_include_sender=false in the
1313 smtp transport.

1585 kind of temporary error. A kludge has been added to help with this.

1614 used only to exclude .Trash (or whatever) when the size of the mailbox

1624
1625PH/01 The code for finding all the local interface addresses on a FreeBSD
1626 system running IPv6 was broken. This may well have applied to all BSD
1627 systems, as well as to others that have similar system calls. The broken
1628 code found IPv4 interfaces correctly, but gave incorrect values for the
1629 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1630 that it would not match correctly against @[] and not recognize the IPv6
1631 addresses as local.

1710 Instead, it always explicitly searches for A/AAAA records. This avoids
1711 major problems that occur when a DNS server includes only records of one
1712 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1713 fixed another bug: if SRV records were looked up and the corresponding
1714 address records were *not* found in the additional section, the port
1715 values from the SRV records were lost.

PH
1725PH/19 When calculating a retry time, Exim used to measure the "time since
1726 failure" by looking at the "first failed" field in the retry record. Now
1727 it does not use this if it is later than than the arrival time of the
1728 message. Instead it uses the arrival time. This makes for better
1729 behaviour in cases where some deliveries succeed, thus re-setting the
1730 "first failed" field. An example is a quota failure for a huge message
1731 when small messages continue to be delivered. Without this change, the
1732 "time since failure" will always be short, possible causing more frequent
1733 delivery attempts for the huge message than are intended.

1830PH/42 The content-scanning code uses fopen() to create files in which to put
1831 message data. Previously it was not paying any attention to the mode of
1832 the files. Exim runs with umask(0) because the rest of the code creates
1833 files with open(), and sets the required mode explicitly. Thus, these
1834 files were ending up world-writeable. This was not a big issue, because,
1835 being within the spool directory, they were not world-accessible. I have
1836 created a function called modefopen, which takes an additional mode
1837 argument. It sets umask(777), creates the file, chmods it to the required
1838 mode, then resets the umask. All the relevant calls to fopen() in the
1839 content scanning code have been changed to use this function.

1876
1877 (i) Exim was not creating retry information for temporary errors given

1879 was used in LMTP mode. This meant that they could be retried too
1880 frequently, and not timed out correctly.
1881
1882 (ii) Exim was setting the flag that allows error details to be returned
1883 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1884 recipients that were returned after the DATA command.
1885
1886PH/53 This is related to PH/52, but is more general: for any failing address,
1887 when detailed error information was permitted to be returned to the

1961 function verify_get_ident() calls ip_connect() to connect a socket, but
1962 if the "connect()" function timed out, ip_connect() used to close the
1963 socket. However, verify_get_ident() also closes the socket later, and in
1964 between Exim writes to the log, which may get opened at this point. When
1965 the socket was closed in ip_connect(), the log could get the same file
1966 descriptor number as the socket. This naturally causes chaos. The fix is
1967 not to close the socket in ip_connect(); the socket should be closed by
1968 the function that creates it. There was only one place in the code where
1969 this was missing, in the iplookup router, which I don't think anybody now
1970 uses, but I've fixed it anyway.

1982 (1) Move the checks for relay_from_hosts and authenticated clients from
1983 after to before the (commented out) DNS black list checks.
1984
1985 (2) Add control=submission to the relay_from_hosts and authenticated
1986 clients checks, on the grounds that messages accepted by these
1987 statements are most likely to be submissions.

PH
1989PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
1990
1991 (1) Generate an error if the third argument for the ${prvs expansion is
1992 not a single digit.
1993
1994 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1995 string.
1996
1997 (3) Reset the variables that are obtained from the first argument of
1998 ${prvscheck and used in the second argument before leaving the code,
1999 because their memory is reclaimed, so using them afterwards may do
2000 silly things.
2001
2002 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2003 one (it's much easier than Tom thought :-).
2004
2005 (5) Because of (4), we can now allow for the use of $prvscheck_result
2006 inside the third argument.

2015PH/05 When a filter generated an autoreply, the entire To: header line was
2016 quoted in the delivery log line, like this:
2017
2018 => >A.N.Other <ano@some.domain> <original@ddress> ...
2019
2020 This has been changed so that it extracts the operative address. There
2021 may be more than one such address. If so, they are comma-separated, like
2022 this:
2023
2024 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2026PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2027 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2028 not being looked up in the rDNS to get a host name, Exim was showing the
2029 IP address twice in Received: lines, even though the IP addresses were
2030 identical. For example:
2031
2032 Received: from [1.2.3.4] (helo=[1.2.3.4])
2033
2034 However, if the real host name was known, it was omitting the HELO data
2035 if it matched the actual IP address. This has been tidied up so that it
2036 doesn't show the same IP address twice.

2038PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2062PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2063 Electronic Mail") by including:
2064
2065 Auto-submitted: auto-generated
2066
2067 in the messages that it generates (bounce messages and others, such as
2068 warnings). In the case of bounce messages for non-SMTP mesages, there was
2069 also a typo: it was using "Auto_submitted" (underscore instead of
2070 hyphen). Since every message generated by Exim is necessarily in response
2071 to another message, thes have all been changed to:
2072
2073 Auto-Submitted: auto-replied
2074
2075 in accordance with these statements in the RFC:
2076
2077 The auto-replied keyword:
2078
2079 - SHOULD be used on messages sent in direct response to another
2080 message by an automatic process,
2081
2082 - MUST NOT be used on manually-generated messages,
2083
2084 - MAY be used on Delivery Status Notifications (DSNs) and Message
2085 Disposition Notifications (MDNs),
2086
2087 - MUST NOT be used on messages generated by automatic or periodic
2088 processes, except for messages which are automatic responses to
2089 other messages.

2125PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2126 canonical form (as documented). However, after a host name lookup from
2127 the IP address, check_host() was doing a simple string comparison with
2128 addresses acquired from the DNS when checking that the found name did
2129 have the original IP as one of its addresses. Since any found IPv6
2130 addresses are likely to be in abbreviated form, the comparison could
2131 fail. Luckily, there already exists a function for doing the comparison
2132 by converting both addresses to binary, so now that is used instead of
2133 the text comparison.
2134
96776534
PH
2135PH/20 There was another similar case to PH/19, when a complete host name was

2397PH/01 When a transport filter timed out in a pipe delivery, and the pipe

2407PH/03 The warning log line about a condition test deferring for a "warn" verb
2408 was being output only once per connection, rather than after each

2412TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that

PH
2430PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2431 with the definition in sysexits.h (which is #included earlier).
2432 Fortunately, Exim does not actually use EX_OK. The code used to try to
2433 preserve the sysexits.h value, by assumimg that macro definitions were
2434 scanned for macro replacements. I have been disabused of this notion,
2435 so now the code just undefines EX_OK before #including unistd.h.

PH
2437PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2438 in the smtp transport. When a block could not be written in a single
2439 write() function, the timeout was being re-applied to each part-write.
2440 This seems wrong - if the receiver was accepting one byte at a time it
2441 would take for ever. The timeout is now adjusted when this happens. It
2442 doesn't have to be particularly precise.

2508PH/15 The code I had for printing potentially long long variables in PH/11

2515PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2516 the configuration file to be ":syslog", then the script "guesses" where
2517 the logs files are, rather than using the compiled in default. In our
2518 case the guess is not the same as the compiled default, so the script
2519 suddenly stopped working when I started to use syslog. The patch checks
2520 to see if log_file_path is "". If so, it attempts to read it from exim
2521 with no configuration file to get the compiled in version, before it
2522 falls back to the previous guessing code."

2572 picked up on a user's system that detects such things. There doesn't seem

PH
2578PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2579 specify a transport. However, if an address that was verified by such a
2580 router was the subject of a callout, Exim crashed because it tried to
2581 read the rcpt_include_affixes from the non-existent transport. Now it
2582 just assumes that the setting of that option is false. This bug was

2593PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These

2650
2651PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2652 that changes the way the GnuTLS parameters are stored in the cache file.
2653 The new format can be generated externally. For backward compatibility,
2654 if the data in the cache doesn't make sense, Exim assumes it has read an
2655 old-format file, and it generates new data and writes a new file. This
2656 means that you can't go back to an older release without removing the
2657 file.
2658
2659PH/03 A redirect router that has both "unseen" and "one_time" set does not
2660 work if there are any delivery delays because "one_time" forces the
2661 parent to be marked "delivered", so its unseen clone is never tried
2662 again. For this reason, Exim now forbids the simultaneous setting of
2663 these two options.
2664
2665PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2666 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2667 entry if you want to know the details. The fix, however, neglected to
2668 consider the case when local delivery batching is involved. The test for
2669 "previously delivered" was not happening when checking to see if an
2670 address could be batched with a previous (undelivered) one; under
2671 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2672 address.
1a46a8c5
PH
2673
2674PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2676
2677PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2678 header_syntax) but Exim was just ignoring anything given after a slash.
2679 In particular, this caused confusion with an attempt to use "verify =
2680 reverse_host_lookup/defer_ok". An error is now given when options are
2681 supplied for verify items that do not have them. (Maybe reverse_host_
2682 lookup should have a defer_ok option, but that's a different point.)
2683
2684PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2736 ownership right at creation (otherwise, other Exim processes might see
2737 the file with the wrong ownership). There was no test for failure of this
2738 fork() call, which would lead to the process getting stuck as it waited
2739 for a non-existent subprocess. Forks do occasionally fail when resources
2740 run out. I reviewed all the other calls to fork(); they all seem to check

2746 the result was a log entry for a synchronization error with an empty
2747 string after "input=" when read() returned zero. If read() returned -1

PH
2760PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it

2762 understands it better than I do:
2763
2764 "Here's what I see happening with three configured cyrus_sasl
2765 authenticators configured (plain, login, cram-md5):
2766
2767 On startup auth_cyrus_sasl_init() gets called for each of these.
2768 This means three calls to sasl_listmech() without a specified mech_list.
2769 => SASL tests which mechs of all available mechs actually work
2770 => three warnings about OTP not working
2771 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2772
2773 With the patch, sasl_listmech() also gets called three times. But now
2774 SASL's mech_list option is set to the server_mech specified in the the
2775 authenticator. Or in other words, the answer from sasl_listmech()
2776 gets limited to just the mech you're testing for (which is different
2777 for each call.)
2778 => the return list contains just 'plain' or 'login', 'cram-md5' or
2779 nothing depending on the value of ob->server_mech.

PH
2847PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2848 the grounds that routing the same address twice would always produce the
2849 same answer. This might have been true once, but it is certainly no
2850 longer true now. Routing a child address may depend on the previous
2851 routing that produced that child. Some complicated redirection strategies
2852 went wrong when messages had multiple recipients, and made Exim's
2853 behaviour dependent on the order in which the addresses were given.
2854
2855 I have moved the duplicate checking until after the routing is complete.
2856 Exim scans the addresses that are assigned to local and remote
2857 transports, and removes any duplicates. This means that more work will be
2858 done, as duplicates will always all be routed, but duplicates are
2859 presumably rare, so I don't expect this is of any significance.
2860
2861 For deliveries to pipes, files, and autoreplies, the duplicate checking
2862 still happens during the routing process, since they are not going to be
2863 routed further.

2908 consistency with the overall process timeout, these timeouts are now
2909 treated as errors, giving rise to delivery failures by default. However,
2910 there is now a new Boolean option for the pipe transport called
2911 timeout_defer, which, if set TRUE, converts the failures into defers for
2912 both kinds of timeout. A transport filter timeout is now identified in

2922A note about Exim versions 4.44 and 4.50
2923----------------------------------------
2924
2925Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2926changes of various kinds. As a consequence, a big documentation update was
2927needed. This delayed the release for rather longer than seemed good, especially
2928in the light of a couple of (minor) security issues. Therefore, the changes
2929that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2930release. So 4.44 and 4.50 are in effect two different branches that both start
2931from 4.43.
2932
2933I have left the 4.50 change log unchanged; it contains all the changes since
29344.43. The change log for 4.44 is below; many of its items are identical to
2935those for 4.50. This seems to be the most sensible way to preserve the
2936historical information.

2954 5. There are several places where Exim runs a non-Exim command in a
2955 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2956 was being done only for the command run by the queryprogram router. It is
2957 now done for all such subprocesses. The other cases are: ${run, transport
2958 filters, and the commands run by the lmtp and pipe transports.

2962 7. Some older OS have a limit of 256 on the maximum number of file
2963 descriptors. Exim was using setrlimit() to set 1000 as a large value
2964 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2965 systems. I've change it so that if it can't get 1000, it tries for 256.

301222. $host_address is now set to the target address during the checking of
3013 ignore_target_hosts.
3014
301523. When checking ignore_target_hosts for an ipliteral router, no host name was
3016 being passed; this would have caused $sender_host_name to have been used if
3017 matching the list had actually called for a host name (not very likely,
3018 since this list is usually IP addresses). A host name is now passed as
3019 "[x.x.x.x]".
3020
7d468ab8
PH
302124. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3022 code that specifies a non-restarting handler (typically sigaction() in
3023 modern systems) in an attempt to fix a rare and obscure crash bug.
3024
302525. Narrowed the window for a race in the daemon that could cause it to ignore
3026 SIGCHLD signals. This is not a major problem, because they are used only to
3027 wake it up if nothing else does.

PH
302926. A malformed maildirsize file could cause Exim to calculate negative values

3031 The maildirsize information is now recalculated if the size or filecount
3032 end up negative.

PH
303929. In an address list, if the pattern was not a regular expression, an empty
3040 subject address (from a bounce message) matched only if the pattern was an
3041 empty string. Non-empty patterns were not even tested. This was the wrong
3042 because it is perfectly reasonable to use an empty address as part of a
3043 database query. An empty address is now tested by patterns that are
3044 lookups. However, all the other forms of pattern expect the subject to
3045 contain a local part and a domain, and therefore, for them, an empty
3046 address still always fails if the pattern is not itself empty.
3047
d8ef3577
PH
304830. Exim went into a mad DNS loop when attempting to do a callout where the
3049 host was specified on an smtp transport, and looking it up yielded more
3050 than one IP address.
3051
5cb8cbc6
PH
305231. Re-factored the code for checking spool and log partition space into a
3053 function that finds that data and another that does the check. The former
3054 is then used to implement four new variables: $spool_space, $log_space,
3055 $spool_inodes, and $log_inodes.
3056
14702f5b
PH
305732. The RFC2047 encoding function was originally intended for short strings
3058 such as real names; it was not keeping to the 75-character limit for
3059 encoded words that the RFC imposes. It now respects the limit, and
3060 generates multiple encoded words if necessary. To be on the safe side, I
3061 have increased the buffer size for the ${rfc2047: expansion operator from
3062 1024 to 2048 bytes.
3063
063b1e99
PH
306433. It is now permitted to omit both strings after an "if" condition; if the
3065 condition is true, the result is "true". As before, when the second string
3066 is omitted, a false condition yields an empty string. This makes it less
3067 cumbersome to write custom ACL and router conditions.
3068
652e1b65
PH
306934. Failure to deliver a bounce message always caused it to be frozen, even if
3070 there was an errors_to setting on the router. The errors_to setting is now
3071 respected.
3072
6f0c9a4f
PH
307335. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3074 canonical form (fully expanded) before being placed in
3075 $sender_host_address.
3076
33397d19
PH
307736. The table in the code that translates DNS record types into text (T_A to
3078 "A" for instance) was missing entries for NS and CNAME. It is just possible
3079 that this could have caused confusion if both these types were looked up
3080 for the same domain, because the text type is used as part of Exim's
3081 per-process caching. But the chance of anyone hitting this buglet seems
3082 very small.
3083
7bb56e1f
PH
308437. The dnsdb lookup has been extended in a number of ways.

3087 finds some nameserver records. It should be used with care.

3089 (2) There is a new type, "mxh", which is like "mx" except that it returns

3147 recorded - for instance if somebody sent an entire SpamAssassin report back
3148 as a large number of 550 error lines. This bug was coincidentally fixed by
3149 increasing the size of one of Exim's internal buffers (big_buffer) that
3150 happened as part of the Exiscan merge. However, to be on the safe side, I
3151 have made the code more robust (and fixed the comments that describe what

315954. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3160 patch that reportedly fixes this has been added. I am not expert enough to
3161 create a test for it. This is what the patch creator wrote:
3162
3163 "I found a little strange behaviour of ldap code when working with
3164 Windows 2003 AD Domain, where users was placed in more than one
3165 Organization Units. When I tried to give exim partial DN, the exit code
3166 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3167 But simultaneously result of request was absolutely normal ldap result,
3168 so I produce this patch..."
3169
3295e65b
PH
3170 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3171 REFERENCE, so I have modified the code to exclude the patch when that macro
3172 is not defined.
3173
7102e136
PH
317455. Some experimental protocols are using DNS PTR records for new purposes. The
3175 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3176 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3177 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
318056. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
3181
c2bcbe20
PH
318257. Double the size of the debug message buffer (to 2048) so that more of very
3183 long debug lines gets shown.
3184
18ce445d
PH
318558. The exicyclog utility now does better if the number of log files to keep
3186 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3187
1f5b4c3d
PH
318859. Two changes related to the smtp_active_hostname option:
3189
3190 (1) $smtp_active_hostname is now available as a variable.
3191 (2) The default for smtp_banner uses $smtp_active_hostname instead
3192 of $primary_hostname.
3193
b975ba52
PH
319460. The host_aton() function is supposed to be passed a string that is known
3195 to be a valid IP address. However, in the case of IPv6 addresses, it was
3196 not checking this. This is a hostage to fortune. Exim now panics and dies
3197 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3198 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3199 components; fortuitously, this particular loophole had already been fixed
3200 by change 4.50/55 above.
3201
3202 If there are any other similar loopholes, the new check in host_aton()
3203 itself should stop them being exploited. The report I received stated that
3204 data on the command line could provoke the exploit when Exim was running as
3205 exim, but did not say which command line option was involved. All I could
3206 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3207 running as the user.

PH
3209
321061. There was a buffer overflow vulnerability in the SPA authentication code
3211 (which came originally from the Samba project). I have added a test to the
3212 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 3213 CAN-2005-0022
b975ba52 3214

PH
321562. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3216 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3217
d95f9fdb
PH
321863. The daemon start-up calls getloadavg() while still root for those OS that
3219 need the first call to be done as root, but it missed one case: when
3220 deliver_queue_load_max is set with deliver_drop_privilege. This is
3221 necessary for the benefit of the queue runner, because there is no re-exec
3222 when deliver_drop_privilege is set.
3223
86b8287f
PH
322464. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3225 This has been fixed.
3226
60dc5e56
PH
322765. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3228 was in use, was not putting the data itself into the right store pool;
3229 consequently, it could be overwritten for a subsequent message in the same
3230 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3231 the caching.)
3232
533244af
PH
323366. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3234
a5a28604
PH
323567. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3236 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3237 the function were treating the return as a boolean value, which happened to
3238 work because 0=false and not-0=true, but is not correct code.
3239
7e634d24
PH
324068. The host_aton() function was not handling scoped IPv6 addresses (those
3241 with, for example, "%eth0" on the end) correctly.
3242
3e11c26b
PH
324369. Fixed some compiler warnings in acl.c for the bitmaps specified with
3244 negated items (that is, ~something) in unsigned ints. Some compilers
3245 apparently mutter when there is no cast.
3246
6729cf78
PH
324770. If an address verification called from an ACL failed, and did not produce a
3248 user-specific message (i.e. there was only a "system" message), nothing was
3249 put in $acl_verify_message. In this situation, it now puts the system
3250 message there.
3251
00f00ca5
PH
325271. Change 4.23/11 added synchronization checking at the start of an SMTP
3253 session; change 4.31/43 added the unwanted input to the log line - except
3254 that it did not do this in the start of session case. It now does.
3255
c9bdd01c
PH
325672. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3257 This is wrong and can cause the other end to generate a synchronization
3258 error if it is another Exim or anything else that does the synchronization
3259 check. A QUIT command is no longer sent after a timeout.
3260
d43194df
PH
326173. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3262 during host lookups.
3263
fe5b5d0b
PH
326474. The defer_ok option of callout verification was not working if it was used
3265 when verifying addresses in header lines, that is, for this case:
3266
3267 verify = header_sender/callout=defer_ok
3268
76a2d7ba
PH
326975. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3270 those file descriptors could be used for SMTP connections. If anything
3271 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3272 could be sent to the SMTP client, causing chaos. The daemon now opens
3273 stdin, stdout, and stderr to /dev/null when it puts itself into the
3274 background.
3275
327676. Arrange for output from Perl's "warn" command to be written to Exim's main
3277 log by default. The user can override this with suitable Perl magic.
3278
04f7d5b9
PH
327977. The use of log_message on a "discard" ACL verb, which is supposed to add to
3280 the log message when discard triggers, was not working for the DATA ACL or
3281 for the non-SMTP ACL.
3282
bc60667e
PH
328378. Error message wording change in sieve.c.
3284
bb6e88ff
PH
328579. If smtp_accept_max_per_host was set, the number of connections could be
3286 restricted to fewer than expected, because the daemon was trying to set up
3287 a new connection before checking whether the processes handling previous
3288 connections had finished. The check for completed processes is now done
3289 earlier. On busy systems, this bug wouldn't be noticed because something
3290 else would have woken the daemon, and it would have reaped the completed
3291 process earlier.
3292
1e70f85b
PH
329380. If a message was submitted locally by a user whose login name contained one
3294 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3295 It caused a spool format error. I have fixed the spool reading code. A
3296 related problem was that the "from" clause in the Received: line became
3297 illegal because of the space(s). It is now covered by ${quote_local_part.
3298
329981. Included the latest eximstats from Steve (adds average sizes to HTML Top
3300 tables).
3301
4e01f9d6
PH
330282. Updated OS/Makefile-AIX as per message from Mike Meredith.

3305 "vacation" handling.

330784. Some minor changes to the Linux configuration files to help with other
3308 OS variants using glibc.

3313----------------------------------------------------
3314See the note above about the 4.44 and 4.50 releases.
3315----------------------------------------------------
3316
3317
3318Exim version 4.44
3319-----------------
3320
3321 1. Change 4.43/35 introduced a bug that caused file counts to be
3322 incorrectly computed when quota_filecount was set in an appendfile
3323 transport
3324
3325 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3326 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3327 place.
3328
3329 3. Give more explanation in the error message when the command for a transport
3330 filter fails to execute.
3331
3332 4. There are several places where Exim runs a non-Exim command in a
3333 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3334 was being done only for the command run by the queryprogram router. It is
3335 now done for all such subprocesses. The other cases are: ${run, transport
3336 filters, and the commands run by the lmtp and pipe transports.
3337
3338 5. Some older OS have a limit of 256 on the maximum number of file
3339 descriptors. Exim was using setrlimit() to set 1000 as a large value
3340 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3341 systems. I've change it so that if it can't get 1000, it tries for 256.
3342
3343 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3344 was an oversight, and furthermore, ever since the addition of extra
3345 controls (e.g. 4.43/32), the checks on when to allow different forms of
3346 "control" were broken. There should now be diagnostics for all cases when a
3347 control that does not make sense is encountered.
3348
3349 7. $recipients is now available in the predata ACL (oversight).
3350
3351 8. Tidy the search cache before the fork to do a delivery from a message
3352 received from the command line. Otherwise the child will trigger a lookup
3353 failure and thereby defer the delivery if it tries to use (for example) a
3354 cached ldap connection that the parent has called unbind on.
3355
3356 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3357 of $address_data from the recipient verification was clobbered by the
3358 sender verification.
3359
336010. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3361 was its contents. (It was OK if the option was not defined at all.)
3362
336311. A "Completed" log line is now written for messages that are removed from
3364 the spool by the -Mrm option.
3365
336612. $host_address is now set to the target address during the checking of
3367 ignore_target_hosts.
3368
336913. When checking ignore_target_hosts for an ipliteral router, no host name was
3370 being passed; this would have caused $sender_host_name to have been used if
3371 matching the list had actually called for a host name (not very likely,
3372 since this list is usually IP addresses). A host name is now passed as
3373 "[x.x.x.x]".
3374
337514. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3376 code that specifies a non-restarting handler (typically sigaction() in
3377 modern systems) in an attempt to fix a rare and obscure crash bug.
3378
337915. Narrowed the window for a race in the daemon that could cause it to ignore
3380 SIGCHLD signals. This is not a major problem, because they are used only to
3381 wake it up if nothing else does.
3382
338316. A malformed maildirsize file could cause Exim to calculate negative values
3384 for the mailbox size or file count. Odd effects could occur as a result.
3385 The maildirsize information is now recalculated if the size or filecount
3386 end up negative.
3387
338817. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3389 support for a long time. Removed HAVE_SYS_VFS_H.
3390
ea3a6f44 339118. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3392
339319. Allow an empty sender to be matched against a lookup in an address list.
3394 Previously the only cases considered were a regular expression, or an
3395 empty pattern.
3396
339720. Exim went into a mad DNS lookup loop when doing a callout where the
3398 host was specified on the transport, if the DNS lookup yielded more than
3399 one IP address.
3400
ea3a6f44
NM
340121. The RFC2047 encoding function was originally intended for short strings
3402 such as real names; it was not keeping to the 75-character limit for
3403 encoded words that the RFC imposes. It now respects the limit, and
3404 generates multiple encoded words if necessary. To be on the safe side, I
3405 have increased the buffer size for the ${rfc2047: expansion operator from
3406 1024 to 2048 bytes.
bbe902f0 3407
ea3a6f44
NM
340822. Failure to deliver a bounce message always caused it to be frozen, even if
3409 there was an errors_to setting on the router. The errors_to setting is now
3410 respected.
