150 when unlink() failed. See also change 4.74-TF/03.
151
921b12ca
TF
152TF/03 Make the exiwhat support code safe for signals. Previously Exim might
153 lock up or crash if it happened to be inside a call to libc when it
154 got a SIGUSR1 from exiwhat.
155
156 The SIGUSR1 handler appends the current process status to the process
157 log which is later printed by exiwhat. It used to use the general
158 purpose logging code to do this, but several functions it calls are
159 not safe for signals.
160
161 The new output code in the SIGUSR1 handler is specific to the process
162 log, and simple enough that it's easy to inspect for signal safety.
163 Removing some special cases also simplifies the general logging code.
164 Removing the spurious timestamps from the process log simplifies
165 exiwhat.
166
c99ce5c9
TF
167TF/04 Improved ratelimit ACL condition.
168
169 The /noupdate option has been deprecated in favour of /readonly which
170 has clearer semantics. The /leaky, /strict, and /readonly update modes
171 are mutually exclusive. The update mode is no longer included in the
172 database key; it just determines when the database is updated. (This
173 means that when you upgrde Exim will forget old rate measurements.)
174
175 Exim now checks that the per_* options are used with an update mode that
176 makes sense for the current ACL. For example, when Exim is processing a
177 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
178 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
179 must specify per_mail/readonly. If you omit the update mode it defaults to
180 /leaky where that makes sense (as before) or /readonly where required.
181
182 The /noupdate option is now undocumented but still supported for
183 backwards compatibility. It is equivalent to /readonly except that in
184 ACLs where /readonly is required you may specify /leaky/noupdate or
185 /strict/noupdate which are treated the same as /readonly.
186
187 A useful new feature is the /count= option. This is a generalization
188 of the per_byte option, so that you can measure the throughput of other
189 aggregate values. For example, the per_byte option is now equivalent
190 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
191
192 The per_rcpt option has been generalized using the /count= mechanism
193 (though it's more complicated than the per_byte equivalence). When it is
194 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
195 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
196 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
197 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
198 Note that using per_rcpt with a non-readonly update mode in more than
199 one ACL will cause the recipients to be double-counted. (The per_mail
200 and per_byte options don't have this problem.)
201
202 The handling of very low rates has changed slightly. If the computed rate
203 is less than the event's count (usually one) then this event is the first
204 after a long gap. In this case the rate is set to the same as this event's
205 count, so that the first message of a spam run is counted properly.
206
207 The major new feature is a mechanism for counting the rate of unique
208 events. The new per_addr option counts the number of different
209 recipients that someone has sent messages to in the last time period. It
210 behaves like per_rcpt if all the recipient addresses are different, but
211 duplicate recipient addresses do not increase the measured rate. Like
212 the /count= option this is a general mechanism, so the per_addr option
213 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
214 example, measure the rate that a client uses different sender addresses
215 with the options per_mail/unique=$sender_address. There are further
216 details in the main documentation.

PH
790PH/02 When an IPv6 address is converted to a string for single-key lookup
791 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
792 dots are used instead of colons so that keys in lsearch files need not
793 contain colons. This was done some time before quoting was made available
794 in lsearch files. However, iplsearch files do require colons in IPv6 keys
795 (notated using the quote facility) so as to distinguish them from IPv4
796 keys. This meant that lookups for IP addresses in host lists did not work
797 for iplsearch lookups.

799 This has been fixed by arranging for IPv6 addresses to be expressed with
800 colons if the lookup type is iplsearch. This is not incompatible, because
801 previously such lookups could never work.
802
803 The situation is now rather anomolous, since one *can* have colons in
804 ordinary lsearch keys. However, making the change in all cases is
805 incompatible and would probably break a number of configurations.

810MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
811 conversion specification without a maximum field width, thereby enabling
812 a rogue spamd server to cause a buffer overflow. While nobody in their
813 right mind would setup Exim to query an untrusted spamd server, an
814 attacker that gains access to a server running spamd could potentially
815 exploit this vulnerability to run arbitrary code as the Exim user.

1012 arrive, invalidly. So now there are extra checks after an ACL has run for
1013 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1014 pipelining has not been advertised.

1088 the response to the final '.' that terminates a message, but only in the
1089 case where the client has not sent further data following the '.'
1090 (unfortunately, this is allowed). However, in many cases there won't be
1091 any further data because there won't be any more messages to send. A call
1092 to select() can be used: if it shows that the input is "ready", there is
1093 either input waiting, or the socket has been closed. An attempt to read
1094 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1095 would have sent an OK response which the client would never have see.

1107 fixed by 4.65/MH/01 (is this a record?) are fixed:
1108
1109 (i) An empty string was always treated as zero by the numeric comparison
1110 operators. This behaviour has been restored.
1111
1112 (ii) It is documented that the numeric comparison operators always treat
1113 their arguments as decimal numbers. This was broken in that numbers
1114 starting with 0 were being interpreted as octal.
1115
1116 While fixing these problems I realized that there was another issue that
1117 hadn't been noticed. Values of message_size_limit (both the global option
1118 and the transport option) were treated as octal if they started with 0.
1119 The documentation was vague. These values are now always treated as
1120 decimal, and I will make that clear in the documentation.

PH
1164PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1165 callout verification, Exim cached a "reject" for the entire domain. This
1166 is correct for most verifications, but it is not correct for a recipient
1167 verification with use_sender or use_postmaster set, because in that case
1168 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1169 case of MAIL FROM:<> rejection from other early rejections (e.g.
1170 rejection of HELO). When verifying a recipient using a non-null MAIL
1171 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1172 Whatever the result of the callout, the value of the domain cache is
1173 left unchanged (for any other kind of callout, getting as far as trying
1174 RCPT means that the domain itself is ok).

1208PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1209 hostname. This is wrong, because it relates to the incoming message (and
1210 probably the interface on which it is arriving) and not to the outgoing
1211 callout (which could be using a different interface). This has been
1212 changed to use the value of the helo_data option from the smtp transport
1213 instead - this is what is used when a message is actually being sent. If
1214 there is no remote transport (possible with a router that sets up host
1215 addresses), $smtp_active_hostname is used.

14aa5a05 1217PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1218 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1219 (a) The code assumed that strncpy() returns a negative number on buffer
1220 overflow, which isn't the case. Replaced with Exim's string_format()
1221 function.
1222 (b) There were several signed/unsigned issues. I just did the minimum
1223 hacking in of casts. There is scope for a larger refactoring.
1224 (c) The code used strcasecmp() which is not a standard C function.
1225 Replaced with Exim's strcmpic() function.
1226 (d) The code set only $1; it now sets $auth1 as well.
1227 (e) A simple test gave the error "authentication client didn't specify
1228 service in request". It would seem that Dovecot has changed its
1229 interface. Fortunately there's a specification; I followed it and
1230 changed what the client sends and it appears to be working now.

PH
1235PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1236 address A is aliased to B and C, where B exists and C does not. Without
1237 -v the output is "A verified" because verification stops after a
1238 successful redirection if more than one address is generated. However,
1239 with -v the child addresses are also verified. Exim was outputting "A
1240 failed to verify" and then showing the successful verification for C,
1241 with its parentage. It now outputs "B failed to verify", showing B's
1242 parentage before showing the successful verification of C.

PH
1244PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1245 look up a TXT record in a specific list after matching in a combined
1246 list.
1247
322050c2
PH
1248PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1249 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1250 they consult the DNS. I had assumed they would set it the way they
1251 wanted; and indeed my experiments on Linux seem to show that in some
1252 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1253 To be on the safe side, however, I have now made the interface to
1254 host_find_byname() similar to host_find_bydns(), with an argument
1255 containing the DNS resolver options. The host_find_byname() function now
1256 sets these options at its start, just as host_find_bydns() does. The smtp
1257 transport options dns_qualify_single and dns_search_parents are passed to
1258 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1259 of host_find_byname() use the default settings of RES_DEFNAMES
1260 (qualify_single) but not RES_DNSRCH (search_parents).
1261

PH
1262PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1263 spool_read_header() do less string testing, by means of a preliminary
1264 switch on the second character of optional "-foo" lines. (This is
1265 overdue, caused by the large number of possibilities that now exist.
1266 Originally there were few.) While I was there, I also converted the
1267 str(n)cmp tests so they don't re-test the leading "-" and the first
1268 character, in the hope this might squeeze out yet more improvement.
1269

PH
1270PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1271 flag allowing group syntax was set by the header_syntax check but not
1272 turned off, possible causing trouble later; (2) The flag was not being
1273 set at all for the header_verify test, causing "group"-style headers to
1274 be rejected. I have now set it in this case, and also caused header_
1275 verify to ignore an empty address taken from a group. While doing this, I
1276 came across some other cases where the code for allowing group syntax
1277 while scanning a header line wasn't quite right (mostly, not resetting
1278 the flag correctly in the right place). These bugs could have caused
1279 trouble for malformed header lines. I hope it is now all correct.
1280
602e59e5
PH
1281PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1282 with the "reply" argument non-NULL. The code, however (which originally
1283 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1284 but it didn't always do it. This confused somebody who was copying the
1285 code for some other use. I have removed all the tests.
1286
411ef850
PH
1287PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1288 feature that was used to support insecure browsers during the U.S. crypto
1289 embargo. It requires special client support, and Exim is probably the
1290 only MTA that supported it -- and would never use it because real RSA is
1291 always available. This code has been removed, because it had the bad
1292 effect of slowing Exim down by computing (never used) parameters for the
1293 RSA_EXPORT functionality.
1294
7befa435
PH
1295PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1296 authenticator to fail if there's a tab character in the incoming data
1297 (there should never be unless someone is messing about, as it's supposed
1298 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1299 if the connection is using TLS or if the remote IP is the same as the
1300 local IP, and the "valid-client-cert option" if a client certificate has
1301 been verified.

PH
1332
1333PH/30 Exim was sometimes attempting to deliver messages that had suffered
1334 address errors (4xx response to RCPT) over the same connection as other
1335 messages routed to the same hosts. Such deliveries are always "forced",
1336 so retry times are not inspected. This resulted in far too many retries
1337 for the affected addresses. The effect occurred only when there were more
1338 hosts than the hosts_max_try setting in the smtp transport when it had
1339 the 4xx errors. Those hosts that it had tried were not added to the list
1340 of hosts for which the message was waiting, so if all were tried, there
1341 was no problem. Two fixes have been applied:
1342
1343 (i) If there are any address or message errors in an SMTP delivery, none
1344 of the hosts (tried or untried) are now added to the list of hosts
1345 for which the message is waiting, so the message should not be a
1346 candidate for sending over the same connection that was used for a
1347 successful delivery of some other message. This seems entirely
1348 reasonable: after all the message is NOT "waiting for some host".
1349 This is so "obvious" that I'm not sure why it wasn't done
1350 previously. Hope I haven't missed anything, but it can't do any
1351 harm, as the worst effect is to miss an optimization.
1352
1353 (ii) If, despite (i), such a delivery is accidentally attempted, the
1354 routing retry time is respected, so at least it doesn't keep
1355 hammering the server.

PH
1370PH/35 The error "getsockname() failed: connection reset by peer" was being
1371 written to the panic log as well as the main log, but it isn't really
1372 panic-worthy as it just means the connection died rather early on. I have
1373 removed the panic log writing for the ECONNRESET error when getsockname()
1374 fails.
1375
48c7f9e2
PH
1376PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1377 runs only) independently of the message's sender address. This meant
1378 that, if the 4xx error was in fact related to the sender, a different
1379 message to the same recipient with a different sender could confuse
1380 things. In particualar, this can happen when sending to a greylisting
1381 server, but other circumstances could also provoke similar problems.
1382 I have changed the default so that the retry time for these errors is now
1383 based a combination of the sender and recipient addresses. This change
1384 can be overridden by setting address_retry_include_sender=false in the
1385 smtp transport.

1653PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1654 "Deny" causes Exim to reject the incoming connection with a 554 error.
1655 Unfortunately, if there is a major crisis, such as a disk failure,
1656 tcp-wrappers gives "deny", whereas what one would like would be some
1657 kind of temporary error. A kludge has been added to help with this.
1658 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1659 554 error is used if errno is still zero or contains ENOENT (which occurs
1660 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1661 451 error is used.

1697PH/01 The code for finding all the local interface addresses on a FreeBSD
1698 system running IPv6 was broken. This may well have applied to all BSD
1699 systems, as well as to others that have similar system calls. The broken
1700 code found IPv4 interfaces correctly, but gave incorrect values for the
1701 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1702 that it would not match correctly against @[] and not recognize the IPv6
1703 addresses as local.

1746 autoreply, Exim could try to deliver to a non-existent relative file

1770 in a subprocess such as that created by queryprogram now generate
1771 suitable debugging ouput when -d is set.

1782 Instead, it always explicitly searches for A/AAAA records. This avoids
1783 major problems that occur when a DNS server includes only records of one
1784 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1785 fixed another bug: if SRV records were looked up and the corresponding
1786 address records were *not* found in the additional section, the port
1787 values from the SRV records were lost.

1797PH/19 When calculating a retry time, Exim used to measure the "time since
1798 failure" by looking at the "first failed" field in the retry record. Now
1799 it does not use this if it is later than than the arrival time of the
1800 message. Instead it uses the arrival time. This makes for better
1801 behaviour in cases where some deliveries succeed, thus re-setting the
1802 "first failed" field. An example is a quota failure for a huge message
1803 when small messages continue to be delivered. Without this change, the
1804 "time since failure" will always be short, possible causing more frequent
1805 delivery attempts for the huge message than are intended.

1902PH/42 The content-scanning code uses fopen() to create files in which to put

1905 files with open(), and sets the required mode explicitly. Thus, these
1906 files were ending up world-writeable. This was not a big issue, because,
1907 being within the spool directory, they were not world-accessible. I have
1908 created a function called modefopen, which takes an additional mode
1909 argument. It sets umask(777), creates the file, chmods it to the required
1910 mode, then resets the umask. All the relevant calls to fopen() in the

1951 was used in LMTP mode. This meant that they could be retried too
1952 frequently, and not timed out correctly.
1953
1954 (ii) Exim was setting the flag that allows error details to be returned
1955 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1956 recipients that were returned after the DATA command.
1957
1958PH/53 This is related to PH/52, but is more general: for any failing address,
1959 when detailed error information was permitted to be returned to the

2032PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2033 function verify_get_ident() calls ip_connect() to connect a socket, but
2034 if the "connect()" function timed out, ip_connect() used to close the
2035 socket. However, verify_get_ident() also closes the socket later, and in
2036 between Exim writes to the log, which may get opened at this point. When
2037 the socket was closed in ip_connect(), the log could get the same file
2038 descriptor number as the socket. This naturally causes chaos. The fix is
2039 not to close the socket in ip_connect(); the socket should be closed by
2040 the function that creates it. There was only one place in the code where
2041 this was missing, in the iplookup router, which I don't think anybody now
2042 uses, but I've fixed it anyway.

2065
2066 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2067 string.
2068
2069 (3) Reset the variables that are obtained from the first argument of
2070 ${prvscheck and used in the second argument before leaving the code,
2071 because their memory is reclaimed, so using them afterwards may do
2072 silly things.
2073
2074 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2075 one (it's much easier than Tom thought :-).
2076

2098PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2099 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2100 not being looked up in the rDNS to get a host name, Exim was showing the
2101 IP address twice in Received: lines, even though the IP addresses were
2102 identical. For example:
2103
2104 Received: from [1.2.3.4] (helo=[1.2.3.4])
2105
2106 However, if the real host name was known, it was omitting the HELO data
2107 if it matched the actual IP address. This has been tidied up so that it
2108 doesn't show the same IP address twice.

2134PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2136
2137 Auto-submitted: auto-generated
2138
2139 in the messages that it generates (bounce messages and others, such as
2140 warnings). In the case of bounce messages for non-SMTP mesages, there was
2141 also a typo: it was using "Auto_submitted" (underscore instead of
2142 hyphen). Since every message generated by Exim is necessarily in response
2143 to another message, thes have all been changed to:
2144
2145 Auto-Submitted: auto-replied
2146
2147 in accordance with these statements in the RFC:
2148
2149 The auto-replied keyword:
2150
2151 - SHOULD be used on messages sent in direct response to another
2152 message by an automatic process,
2153

2157 Disposition Notifications (MDNs),

2197PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2198 canonical form (as documented). However, after a host name lookup from
2199 the IP address, check_host() was doing a simple string comparison with
2200 addresses acquired from the DNS when checking that the found name did
2201 have the original IP as one of its addresses. Since any found IPv6
2202 addresses are likely to be in abbreviated form, the comparison could
2203 fail. Luckily, there already exists a function for doing the comparison
2204 by converting both addresses to binary, so now that is used instead of
2205 the text comparison.

2207PH/20 There was another similar case to PH/19, when a complete host name was

2503 with the definition in sysexits.h (which is #included earlier).
2504 Fortunately, Exim does not actually use EX_OK. The code used to try to
2505 preserve the sysexits.h value, by assumimg that macro definitions were
2506 scanned for macro replacements. I have been disabused of this notion,
2507 so now the code just undefines EX_OK before #including unistd.h.

2512 This seems wrong - if the receiver was accepting one byte at a time it
2513 would take for ever. The timeout is now adjusted when this happens. It
2514 doesn't have to be particularly precise.

2723PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2724 that changes the way the GnuTLS parameters are stored in the cache file.
2725 The new format can be generated externally. For backward compatibility,
2726 if the data in the cache doesn't make sense, Exim assumes it has read an
2727 old-format file, and it generates new data and writes a new file. This
2728 means that you can't go back to an older release without removing the
2729 file.
2730
2731PH/03 A redirect router that has both "unseen" and "one_time" set does not
2732 work if there are any delivery delays because "one_time" forces the
2733 parent to be marked "delivered", so its unseen clone is never tried
2734 again. For this reason, Exim now forbids the simultaneous setting of
2735 these two options.
2736
2737PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2738 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2739 entry if you want to know the details. The fix, however, neglected to
2740 consider the case when local delivery batching is involved. The test for
2741 "previously delivered" was not happening when checking to see if an
2742 address could be batched with a previous (undelivered) one; under
2743 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2744 address.

2749PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2750 header_syntax) but Exim was just ignoring anything given after a slash.
2751 In particular, this caused confusion with an attempt to use "verify =
2752 reverse_host_lookup/defer_ok". An error is now given when options are
2753 supplied for verify items that do not have them. (Maybe reverse_host_
2754 lookup should have a defer_ok option, but that's a different point.)
2755
2756PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2806PH/19 When an Exim process that is running as root has to create an Exim log
2807 file, it does so in a subprocess that runs as exim:exim so as to get the
2808 ownership right at creation (otherwise, other Exim processes might see
2809 the file with the wrong ownership). There was no test for failure of this
2810 fork() call, which would lead to the process getting stuck as it waited
2811 for a non-existent subprocess. Forks do occasionally fail when resources
2812 run out. I reviewed all the other calls to fork(); they all seem to check

2815PH/20 When checking for unexpected SMTP input at connect time (before writing

2818 the result was a log entry for a synchronization error with an empty
2819 string after "input=" when read() returned zero. If read() returned -1

c5ddb310
PH
2832PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2833 hadn't been configured. The fix is from Juergen Kreileder, who
2834 understands it better than I do:
2835
2836 "Here's what I see happening with three configured cyrus_sasl
2837 authenticators configured (plain, login, cram-md5):
2838
2839 On startup auth_cyrus_sasl_init() gets called for each of these.
2840 This means three calls to sasl_listmech() without a specified mech_list.
2841 => SASL tests which mechs of all available mechs actually work
2842 => three warnings about OTP not working
2843 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2844
2845 With the patch, sasl_listmech() also gets called three times. But now
2846 SASL's mech_list option is set to the server_mech specified in the the
2847 authenticator. Or in other words, the answer from sasl_listmech()
2848 gets limited to just the mech you're testing for (which is different
2849 for each call.)
2850 => the return list contains just 'plain' or 'login', 'cram-md5' or
2851 nothing depending on the value of ob->server_mech.
2852
2853 I've just tested the patch: Authentication still works fine,
2854 unavailable mechs specified in the exim configuration are still
2855 caught, and the auth.log warnings about OTP are gone."

PH
2919PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2920 the grounds that routing the same address twice would always produce the
2921 same answer. This might have been true once, but it is certainly no
2922 longer true now. Routing a child address may depend on the previous
2923 routing that produced that child. Some complicated redirection strategies
2924 went wrong when messages had multiple recipients, and made Exim's
2925 behaviour dependent on the order in which the addresses were given.
2926
2927 I have moved the duplicate checking until after the routing is complete.
2928 Exim scans the addresses that are assigned to local and remote
2929 transports, and removes any duplicates. This means that more work will be
2930 done, as duplicates will always all be routed, but duplicates are
2931 presumably rare, so I don't expect this is of any significance.
2932
2933 For deliveries to pipes, files, and autoreplies, the duplicate checking
2934 still happens during the routing process, since they are not going to be
2935 routed further.

2980 consistency with the overall process timeout, these timeouts are now
2981 treated as errors, giving rise to delivery failures by default. However,
2982 there is now a new Boolean option for the pipe transport called
2983 timeout_defer, which, if set TRUE, converts the failures into defers for
2984 both kinds of timeout. A transport filter timeout is now identified in

2994A note about Exim versions 4.44 and 4.50
2995----------------------------------------
2996
2997Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2998changes of various kinds. As a consequence, a big documentation update was
2999needed. This delayed the release for rather longer than seemed good, especially
3000in the light of a couple of (minor) security issues. Therefore, the changes
3001that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3002release. So 4.44 and 4.50 are in effect two different branches that both start
3003from 4.43.
3004
3005I have left the 4.50 change log unchanged; it contains all the changes since
30064.43. The change log for 4.44 is below; many of its items are identical to
3007those for 4.50. This seems to be the most sensible way to preserve the
3008historical information.

3026 5. There are several places where Exim runs a non-Exim command in a
3027 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3028 was being done only for the command run by the queryprogram router. It is
3029 now done for all such subprocesses. The other cases are: ${run, transport
3030 filters, and the commands run by the lmtp and pipe transports.

3034 7. Some older OS have a limit of 256 on the maximum number of file
3035 descriptors. Exim was using setrlimit() to set 1000 as a large value
3036 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3037 systems. I've change it so that if it can't get 1000, it tries for 256.

3085 ignore_target_hosts.
3086
308723. When checking ignore_target_hosts for an ipliteral router, no host name was
3088 being passed; this would have caused $sender_host_name to have been used if
3089 matching the list had actually called for a host name (not very likely,
3090 since this list is usually IP addresses). A host name is now passed as
3091 "[x.x.x.x]".

309324. Changed the calls that set up the SIGCHLD handler in the daemon to use the

3096
309725. Narrowed the window for a race in the daemon that could cause it to ignore

311129. In an address list, if the pattern was not a regular expression, an empty
3112 subject address (from a bounce message) matched only if the pattern was an
3113 empty string. Non-empty patterns were not even tested. This was the wrong
3114 because it is perfectly reasonable to use an empty address as part of a
3115 database query. An empty address is now tested by patterns that are
3116 lookups. However, all the other forms of pattern expect the subject to
3117 contain a local part and a domain, and therefore, for them, an empty
3118 address still always fails if the pattern is not itself empty.

312030. Exim went into a mad DNS loop when attempting to do a callout where the

PH
312431. Re-factored the code for checking spool and log partition space into a
3125 function that finds that data and another that does the check. The former

3127 $spool_inodes, and $log_inodes.

PH
312932. The RFC2047 encoding function was originally intended for short strings
3130 such as real names; it was not keeping to the 75-character limit for
3131 encoded words that the RFC imposes. It now respects the limit, and
3132 generates multiple encoded words if necessary. To be on the safe side, I
3133 have increased the buffer size for the ${rfc2047: expansion operator from
3134 1024 to 2048 bytes.

PH
313633. It is now permitted to omit both strings after an "if" condition; if the
3137 condition is true, the result is "true". As before, when the second string
3138 is omitted, a false condition yields an empty string. This makes it less
3139 cumbersome to write custom ACL and router conditions.

314936. The table in the code that translates DNS record types into text (T_A to
3150 "A" for instance) was missing entries for NS and CNAME. It is just possible
3151 that this could have caused confusion if both these types were looked up
3152 for the same domain, because the text type is used as part of Exim's
3153 per-process caching. But the chance of anyone hitting this buglet seems
3154 very small.

3165 looked up. The behaviour when one of the lookups defers can be
3166 controlled by a keyword.
7bb56e1f 3167
ea3bc19b 3168 (4) It is now possible to specify the separator character for use when
7bb56e1f 3169 multiple records are returned.

PH
317138. The dnslists ACL condition has been extended: it is now possible to supply
3172 a list of IP addresses and/or domains to be looked up in a particular DNS
3173 domain.

PH
317539. Added log_selector=+queue_time_overall.
3176

PH
317740. When running the queue in the test harness, wait just a tad after forking a
3178 delivery process, to get repeatability of debugging output.

PH
318041. Include certificate and key file names in error message when GnuTLS fails
3181 to set them up, because the GnuTLS error message doesn't include the name
3182 of the failing file when there is a problem reading it.
3183

PH
318442. Allow both -bf and -bF in the same test run.

PH
318643. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3187
f7b63901
PH
318844. The "Exiscan patch" is now merged into the mainline Exim source.
3189
319045. Sometimes the final signoff response after QUIT could fail to get
3191 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3192 < 0 before doing a fflush(). This bug looks as though it goes back to the
3193 introduction of TLS in release 3.20, but "sometimes" must have been rare
3194 because the tests only now provoked it.
3195

PH
319646. Reset the locale to "C" after calling embedded Perl, in case it was changed
3197 (this can affect the format of dates).
3198

PH
319947. exim_tidydb, when checking for the continued existence of a message for
3200 which it has found a message-specific retry record, was not finding
3201 messages that were in split spool directories. Consequently, it was
3202 deleting retry records that should have stayed in existence.
3203
b1206957
PH
320448. Steve fixed some bugs in eximstats.
3205
320649. The SPA authentication driver was not abandoning authentication and moving
3207 on to the next authenticator when an expansion was forced to fail,
3208 contradicting the general specification for all authenticators. Instead it
3209 was generating a temporary error. It now behaves as specified.
3210
26dd5a95
PH
321150. The default ordering of permitted cipher suites for GnuTLS was pessimal
3212 (the order specifies the preference for clients). The order is now AES256,
3213 AES128, 3DES, ARCFOUR128.
3214

PH
321551. Small patch to Sieve code - explicitly set From: when generating an
3216 autoreply.
3217
1c5466b9
PH
321852. Exim crashed if a remote delivery caused a very long error message to be
3219 recorded - for instance if somebody sent an entire SpamAssassin report back
3220 as a large number of 550 error lines. This bug was coincidentally fixed by
3221 increasing the size of one of Exim's internal buffers (big_buffer) that
3222 happened as part of the Exiscan merge. However, to be on the safe side, I
3223 have made the code more robust (and fixed the comments that describe what
3224 is going on).
3225
55ee9ee3
PH
322653. Now that there can be additional text after "Completed" in log lines (if
3227 the queue_time_overall log selector is set), a one-byte patch to exigrep
3228 was needed to allow it to recognize "Completed" as not the last thing in
3229 the line.
3230
d38f8232
PH
323154. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3232 patch that reportedly fixes this has been added. I am not expert enough to
3233 create a test for it. This is what the patch creator wrote:
3234
3235 "I found a little strange behaviour of ldap code when working with
3236 Windows 2003 AD Domain, where users was placed in more than one
3237 Organization Units. When I tried to give exim partial DN, the exit code
3238 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3239 But simultaneously result of request was absolutely normal ldap result,
3240 so I produce this patch..."
3241
3295e65b
PH
3242 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3243 REFERENCE, so I have modified the code to exclude the patch when that macro
3244 is not defined.
3245
7102e136
PH
324655. Some experimental protocols are using DNS PTR records for new purposes. The
3247 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3248 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3249 leaves it alone. Component reversal etc. now happens only for IP addresses.

3255 long debug lines gets shown.
3256

PH
325758. The exicyclog utility now does better if the number of log files to keep
3258 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3259

PH
326059. Two changes related to the smtp_active_hostname option:
3261
3262 (1) $smtp_active_hostname is now available as a variable.
3263 (2) The default for smtp_banner uses $smtp_active_hostname instead
3264 of $primary_hostname.
3265
b975ba52
PH
326660. The host_aton() function is supposed to be passed a string that is known
3267 to be a valid IP address. However, in the case of IPv6 addresses, it was
3268 not checking this. This is a hostage to fortune. Exim now panics and dies
3269 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3270 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3271 components; fortuitously, this particular loophole had already been fixed
3272 by change 4.50/55 above.
3273
3274 If there are any other similar loopholes, the new check in host_aton()
3275 itself should stop them being exploited. The report I received stated that
3276 data on the command line could provoke the exploit when Exim was running as
3277 exim, but did not say which command line option was involved. All I could
3278 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3279 running as the user.

328261. There was a buffer overflow vulnerability in the SPA authentication code
3283 (which came originally from the Samba project). I have added a test to the
3284 spa_base64_to_bits() function which I hope fixes it.

3288 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3289

PH
329063. The daemon start-up calls getloadavg() while still root for those OS that
3291 need the first call to be done as root, but it missed one case: when
3292 deliver_queue_load_max is set with deliver_drop_privilege. This is
3293 necessary for the benefit of the queue runner, because there is no re-exec
3294 when deliver_drop_privilege is set.
3295
86b8287f
PH
329664. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3297 This has been fixed.
3298
60dc5e56
PH
329965. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3300 was in use, was not putting the data itself into the right store pool;
3301 consequently, it could be overwritten for a subsequent message in the same
3302 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3303 the caching.)
3304
533244af
PH
330566. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3306
a5a28604
PH
330767. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3308 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3309 the function were treating the return as a boolean value, which happened to
3310 work because 0=false and not-0=true, but is not correct code.
3311
7e634d24
PH
331268. The host_aton() function was not handling scoped IPv6 addresses (those
3313 with, for example, "%eth0" on the end) correctly.
3314
3e11c26b
PH
331569. Fixed some compiler warnings in acl.c for the bitmaps specified with
3316 negated items (that is, ~something) in unsigned ints. Some compilers
3317 apparently mutter when there is no cast.
3318
6729cf78
PH
331970. If an address verification called from an ACL failed, and did not produce a
3320 user-specific message (i.e. there was only a "system" message), nothing was
3321 put in $acl_verify_message. In this situation, it now puts the system
3322 message there.
3323
00f00ca5
PH
332471. Change 4.23/11 added synchronization checking at the start of an SMTP
3325 session; change 4.31/43 added the unwanted input to the log line - except
3326 that it did not do this in the start of session case. It now does.
3327
c9bdd01c
PH
332872. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3329 This is wrong and can cause the other end to generate a synchronization
3330 error if it is another Exim or anything else that does the synchronization
3331 check. A QUIT command is no longer sent after a timeout.
3332
d43194df
PH
333373. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3334 during host lookups.
3335
fe5b5d0b
PH
333674. The defer_ok option of callout verification was not working if it was used
3337 when verifying addresses in header lines, that is, for this case:
3338
3339 verify = header_sender/callout=defer_ok
3340
76a2d7ba
PH
334175. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3342 those file descriptors could be used for SMTP connections. If anything
3343 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3344 could be sent to the SMTP client, causing chaos. The daemon now opens
3345 stdin, stdout, and stderr to /dev/null when it puts itself into the
3346 background.
3347
334876. Arrange for output from Perl's "warn" command to be written to Exim's main
3349 log by default. The user can override this with suitable Perl magic.
3350
04f7d5b9
PH
335177. The use of log_message on a "discard" ACL verb, which is supposed to add to
3352 the log message when discard triggers, was not working for the DATA ACL or
3353 for the non-SMTP ACL.
3354
bc60667e
PH
335578. Error message wording change in sieve.c.
3356
bb6e88ff
PH
335779. If smtp_accept_max_per_host was set, the number of connections could be
3358 restricted to fewer than expected, because the daemon was trying to set up
3359 a new connection before checking whether the processes handling previous
3360 connections had finished. The check for completed processes is now done
3361 earlier. On busy systems, this bug wouldn't be noticed because something
3362 else would have woken the daemon, and it would have reaped the completed
3363 process earlier.
3364
1e70f85b
PH
336580. If a message was submitted locally by a user whose login name contained one
3366 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3367 It caused a spool format error. I have fixed the spool reading code. A
3368 related problem was that the "from" clause in the Received: line became
3369 illegal because of the space(s). It is now covered by ${quote_local_part.
3370
337181. Included the latest eximstats from Steve (adds average sizes to HTML Top
3372 tables).
