11GF/01 DEFER rather than ERROR on redis cluster MOVED response.
12 When redis_servers is set to a list of > 1 element, and the Redis servers
13 in that list are in cluster configuration, convert the REDIS_REPLY_ERROR
14 case of MOVED into a DEFER case instead, thus moving the query onto the
15 next server in the list. For a cluster of N elements, all N servers must
16 be defined in redis_servers.

32JH/04 Bug 2217: Tighten up the parsing of DKIM signature headers. Previously
33 we assumed that tags in the header were well-formed, and parsed the
34 element content after inspecting only the first char of the tag.
35 Assumptions at that stage could crash the receive process on malformed
36 input.

38JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
39 While running the DKIM ACL we operate on the Permanent memory pool so that
40 variables created with "set" persist to the DATA ACL. Also (at any time)
41 DNS lookups that fail create cache records using the Permanent pool. But
42 expansions release any allocations made on the current pool - so a dnsdb
43 lookup expansion done in the DKIM ACL releases the memory used for the
44 DNS negative-cache, and bad things result. Solution is to switch to the
45 Main pool for expansions.
46 While we're in that code, add checks on the DNS cache during store_reset,
47 active in the testsuite.
48 Problem spotted, and debugging aided, by Wolfgang Breyha.

50JH/06 Fix issue with continued-connections when the DNS shifts unreliably.
51 When none of the hosts presented to a transport match an already-open

53 queue the message. Spotted by Lena with Yahoo, probably involving
54 round-robin DNS.

84JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as

155JH/29 Bug 2250: Fix a longstanding bug in heavily-pipelined SMTP input (such
156 as a multi-recipient message from a mailinglist manager). The coding had
157 an arbitrary cutoff number of characters while checking for more input;
158 enforced by writing a NUL into the buffer. This corrupted long / fast
159 input. The problem was exposed more widely when more pipelineing of SMTP
160 responses was introduced, and one Exim system was feeding another.
161 The symptom is log complaints of SMTP syntax error (NUL chars) on the
162 receiving system, and refused recipients seen by the sending system
163 (propating to people being dropped from mailing lists).
164 Discovered and pinpointed by David Carter.

192JH/03 Rework the transport continued-connection mechanism: when TLS is active,
193 do not close it down and have the child transport start it up again on
194 the passed-on TCP connection. Instead, proxy the child (and any
195 subsequent ones) for TLS via a unix-domain socket channel. Logging is
196 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 197 Certificate or OCSP information. TLS cipher information is still logged.

211 Disable the session-cache too, which might reduce our load. Since we
212 currrectly use a new context for every connection, both as server and
213 client, there is no benefit for these.
214 GnuTLS appears to not support tickets server-side by default (we don't
215 call gnutls_session_ticket_enable_server()) but client side is enabled
216 by default on recent versions (3.1.3 +) unless the PFS priority string

238JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
239 case where the routing stage had gathered several addresses to send to
240 a host before calling the transport for the first, we previously failed
241 to close down TLS in the old transport process before passing the TCP
242 connection to the new process. The new one sent a STARTTLS command
243 which naturally failed, giving a failed delivery and bloating the retry
244 database. Investigation and fix prototype from Wolfgang Breyha.
245

JH
246JH/12 Fix check on SMTP command input synchronisation. Previously there were
247 false-negatives in the check that the sender had not preempted a response
248 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 249 awareness of the SMTP input buffering.

251PP/04 Add commandline_checks_require_admin option.
252 Exim drops privileges sanely, various checks such as -be aren't a
253 security problem, as long as you trust local users with access to their
254 own account. When invoked by services which pass untrusted data to
255 Exim, this might be an issue. Set this option in main configuration
256 AND make fixes to the calling application, such as using `--` to stop
257 processing options.
258

JH
259JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
260 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
261 responses to those, into a single TLS record each way (this usually means
262 a single packet). As a side issue, smtp_enforce_sync now works on TLS
263 connections.

433JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
434 TCP connections (such as for Spamd) unless the daemon successfully set
435 Fast Open mode on its listening sockets. This fixes breakage seen on
436 too-old kernels or those not configured for Fast Open, at the cost of
437 requiring both directions being enabled for TFO, and TFO never being used

499JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
500 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
501 or even an in-clear connection were permitted. Now, if the host lookup
502 was dnssec and dane was requested then the host is only used if the
503 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
504 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
505 if one fails this test.
506 This means that a poorly-configured remote DNS will make it incommunicado;
507 but it protects against a DNS-interception attack on it.

788JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
789 incorrectly not doubled on cutthrough transmission, hence seen as a

1321TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1322
1323 When a queue runner is handling a message, Exim first routes the
1324 recipient addresses, during which it prunes them based on the retry
1325 hints database. After that it attempts to deliver the message to
1326 any remaining recipients. It then updates the hints database using
1327 the retry rules.
1328
1329 So if a recipient address works intermittently, it can get repeatedly
1330 deferred at routing time. The retry hints record remains fresh so the
1331 address never reaches the final cutoff time.
1332
1333 This is a fairly common occurrence when a user is bumping up against
1334 their storage quota. Exim had some logic in its local delivery code
1335 to deal with this. However it did not apply to per-recipient defers
1336 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1337
1ddeb334
TF
1338 This change adds a proper retry rule check during routing so that the
1339 final cutoff time is checked against the message's age. We only do
1340 this check if there is an address retry record and there is not a
1341 domain retry record; this implies that previous attempts to handle
1342 the address had the retry_use_local_parts option turned on. We use
1343 this as an approximation for the destination being like a local
1344 delivery, as in LMTP.
67bd1ab3
TF
1345
1346 I suspect this new check makes the old local delivery cutoff check
1347 redundant, but I have not verified this so I left the code in place.

1356 the header to contain my full name, whereas it should have added
1357 a Resent-Sender: header. It erroneously treats any prefix of the

1387 the body content is received and before the acl_smtp_data ACL.

1669TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1670 lock up or crash if it happened to be inside a call to libc when it
1671 got a SIGUSR1 from exiwhat.
1672
1673 The SIGUSR1 handler appends the current process status to the process
1674 log which is later printed by exiwhat. It used to use the general
1675 purpose logging code to do this, but several functions it calls are
1676 not safe for signals.
1677
1678 The new output code in the SIGUSR1 handler is specific to the process
1679 log, and simple enough that it's easy to inspect for signal safety.
1680 Removing some special cases also simplifies the general logging code.
1681 Removing the spurious timestamps from the process log simplifies
1682 exiwhat.
1683
c99ce5c9
TF
1684TF/04 Improved ratelimit ACL condition.
1685
1686 The /noupdate option has been deprecated in favour of /readonly which
1687 has clearer semantics. The /leaky, /strict, and /readonly update modes
1688 are mutually exclusive. The update mode is no longer included in the
1689 database key; it just determines when the database is updated. (This
4c04137d 1690 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1691
1692 Exim now checks that the per_* options are used with an update mode that
1693 makes sense for the current ACL. For example, when Exim is processing a
1694 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1695 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1696 must specify per_mail/readonly. If you omit the update mode it defaults to
1697 /leaky where that makes sense (as before) or /readonly where required.
1698
1699 The /noupdate option is now undocumented but still supported for
1700 backwards compatibility. It is equivalent to /readonly except that in
1701 ACLs where /readonly is required you may specify /leaky/noupdate or
1702 /strict/noupdate which are treated the same as /readonly.
1703
1704 A useful new feature is the /count= option. This is a generalization
1705 of the per_byte option, so that you can measure the throughput of other
1706 aggregate values. For example, the per_byte option is now equivalent
1707 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1708
1709 The per_rcpt option has been generalized using the /count= mechanism
1710 (though it's more complicated than the per_byte equivalence). When it is
1711 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1712 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1713 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1714 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1715 Note that using per_rcpt with a non-readonly update mode in more than
1716 one ACL will cause the recipients to be double-counted. (The per_mail
1717 and per_byte options don't have this problem.)
1718
1719 The handling of very low rates has changed slightly. If the computed rate
1720 is less than the event's count (usually one) then this event is the first
1721 after a long gap. In this case the rate is set to the same as this event's
1722 count, so that the first message of a spam run is counted properly.
1723
1724 The major new feature is a mechanism for counting the rate of unique
1725 events. The new per_addr option counts the number of different
1726 recipients that someone has sent messages to in the last time period. It
1727 behaves like per_rcpt if all the recipient addresses are different, but
1728 duplicate recipient addresses do not increase the measured rate. Like
1729 the /count= option this is a general mechanism, so the per_addr option
1730 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1731 example, measure the rate that a client uses different sender addresses
1732 with the options per_mail/unique=$sender_address. There are further
1733 details in the main documentation.

1943PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
1944 If dropping privileges for untrusted macros, we disabled normal logging
1945 on the basis that it would fail; for the Exim run-time user, this is not
1946 the case, and it resulted in successful deliveries going unlogged.
1947 Fixed. Reported by Andreas Metzler.

2308 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2309 dots are used instead of colons so that keys in lsearch files need not
2310 contain colons. This was done some time before quoting was made available
2311 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2312 (notated using the quote facility) so as to distinguish them from IPv4
2313 keys. This meant that lookups for IP addresses in host lists did not work
2314 for iplsearch lookups.
2315
2316 This has been fixed by arranging for IPv6 addresses to be expressed with
2317 colons if the lookup type is iplsearch. This is not incompatible, because
2318 previously such lookups could never work.
2319
4c04137d 2320 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2321 ordinary lsearch keys. However, making the change in all cases is
2322 incompatible and would probably break a number of configurations.

2327MH/01 The "spam" ACL condition code contained a sscanf() call with a %s

2329 a rogue spamd server to cause a buffer overflow. While nobody in their
2330 right mind would setup Exim to query an untrusted spamd server, an
2331 attacker that gains access to a server running spamd could potentially
2332 exploit this vulnerability to run arbitrary code as the Exim user.

2528 some time before the response is written. In this time, more input might
2529 arrive, invalidly. So now there are extra checks after an ACL has run for
2530 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when

2605 the response to the final '.' that terminates a message, but only in the
2606 case where the client has not sent further data following the '.'
2607 (unfortunately, this is allowed). However, in many cases there won't be
2608 any further data because there won't be any more messages to send. A call
2609 to select() can be used: if it shows that the input is "ready", there is
2610 either input waiting, or the socket has been closed. An attempt to read
2611 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2612 would have sent an OK response which the client would never have see.

2624 fixed by 4.65/MH/01 (is this a record?) are fixed:
2625
2626 (i) An empty string was always treated as zero by the numeric comparison
2627 operators. This behaviour has been restored.
2628
2629 (ii) It is documented that the numeric comparison operators always treat
2630 their arguments as decimal numbers. This was broken in that numbers
2631 starting with 0 were being interpreted as octal.
2632
2633 While fixing these problems I realized that there was another issue that
2634 hadn't been noticed. Values of message_size_limit (both the global option
2635 and the transport option) were treated as octal if they started with 0.
2636 The documentation was vague. These values are now always treated as
2637 decimal, and I will make that clear in the documentation.

PH
2681PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2682 callout verification, Exim cached a "reject" for the entire domain. This
2683 is correct for most verifications, but it is not correct for a recipient
2684 verification with use_sender or use_postmaster set, because in that case
2685 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2686 case of MAIL FROM:<> rejection from other early rejections (e.g.
2687 rejection of HELO). When verifying a recipient using a non-null MAIL
2688 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2689 Whatever the result of the callout, the value of the domain cache is
2690 left unchanged (for any other kind of callout, getting as far as trying
2691 RCPT means that the domain itself is ok).

2725PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2726 hostname. This is wrong, because it relates to the incoming message (and
2727 probably the interface on which it is arriving) and not to the outgoing
2728 callout (which could be using a different interface). This has been
2729 changed to use the value of the helo_data option from the smtp transport
2730 instead - this is what is used when a message is actually being sent. If
2731 there is no remote transport (possible with a router that sets up host
2732 addresses), $smtp_active_hostname is used.

14aa5a05 2734PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2735 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2736 (a) The code assumed that strncpy() returns a negative number on buffer
2737 overflow, which isn't the case. Replaced with Exim's string_format()
2738 function.
2739 (b) There were several signed/unsigned issues. I just did the minimum
2740 hacking in of casts. There is scope for a larger refactoring.
2741 (c) The code used strcasecmp() which is not a standard C function.
2742 Replaced with Exim's strcmpic() function.
2743 (d) The code set only $1; it now sets $auth1 as well.
2744 (e) A simple test gave the error "authentication client didn't specify
2745 service in request". It would seem that Dovecot has changed its
2746 interface. Fortunately there's a specification; I followed it and
2747 changed what the client sends and it appears to be working now.

2752PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2753 address A is aliased to B and C, where B exists and C does not. Without
2754 -v the output is "A verified" because verification stops after a
2755 successful redirection if more than one address is generated. However,
2756 with -v the child addresses are also verified. Exim was outputting "A
2757 failed to verify" and then showing the successful verification for C,
2758 with its parentage. It now outputs "B failed to verify", showing B's
2759 parentage before showing the successful verification of C.

2762 look up a TXT record in a specific list after matching in a combined

2764
322050c2
PH
2765PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2766 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2767 they consult the DNS. I had assumed they would set it the way they
2768 wanted; and indeed my experiments on Linux seem to show that in some
2769 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2770 To be on the safe side, however, I have now made the interface to
2771 host_find_byname() similar to host_find_bydns(), with an argument
2772 containing the DNS resolver options. The host_find_byname() function now
2773 sets these options at its start, just as host_find_bydns() does. The smtp
2774 transport options dns_qualify_single and dns_search_parents are passed to
2775 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2776 of host_find_byname() use the default settings of RES_DEFNAMES
2777 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2779PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2780 spool_read_header() do less string testing, by means of a preliminary
2781 switch on the second character of optional "-foo" lines. (This is
2782 overdue, caused by the large number of possibilities that now exist.
2783 Originally there were few.) While I was there, I also converted the
2784 str(n)cmp tests so they don't re-test the leading "-" and the first
2785 character, in the hope this might squeeze out yet more improvement.
2786

PH
2787PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2788 flag allowing group syntax was set by the header_syntax check but not
2789 turned off, possible causing trouble later; (2) The flag was not being
2790 set at all for the header_verify test, causing "group"-style headers to
2791 be rejected. I have now set it in this case, and also caused header_
2792 verify to ignore an empty address taken from a group. While doing this, I
2793 came across some other cases where the code for allowing group syntax
2794 while scanning a header line wasn't quite right (mostly, not resetting
2795 the flag correctly in the right place). These bugs could have caused
2796 trouble for malformed header lines. I hope it is now all correct.
2797
602e59e5
PH
2798PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2799 with the "reply" argument non-NULL. The code, however (which originally
2800 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2801 but it didn't always do it. This confused somebody who was copying the
2802 code for some other use. I have removed all the tests.
2803
411ef850
PH
2804PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2805 feature that was used to support insecure browsers during the U.S. crypto
2806 embargo. It requires special client support, and Exim is probably the
2807 only MTA that supported it -- and would never use it because real RSA is
2808 always available. This code has been removed, because it had the bad
2809 effect of slowing Exim down by computing (never used) parameters for the
2810 RSA_EXPORT functionality.
2811
7befa435
PH
2812PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2813 authenticator to fail if there's a tab character in the incoming data
2814 (there should never be unless someone is messing about, as it's supposed
2815 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2816 if the connection is using TLS or if the remote IP is the same as the
2817 local IP, and the "valid-client-cert option" if a client certificate has
2818 been verified.

PH
2849
2850PH/30 Exim was sometimes attempting to deliver messages that had suffered
2851 address errors (4xx response to RCPT) over the same connection as other
2852 messages routed to the same hosts. Such deliveries are always "forced",
2853 so retry times are not inspected. This resulted in far too many retries
2854 for the affected addresses. The effect occurred only when there were more
2855 hosts than the hosts_max_try setting in the smtp transport when it had
2856 the 4xx errors. Those hosts that it had tried were not added to the list
2857 of hosts for which the message was waiting, so if all were tried, there
2858 was no problem. Two fixes have been applied:
2859
2860 (i) If there are any address or message errors in an SMTP delivery, none
2861 of the hosts (tried or untried) are now added to the list of hosts
2862 for which the message is waiting, so the message should not be a
2863 candidate for sending over the same connection that was used for a
2864 successful delivery of some other message. This seems entirely
2865 reasonable: after all the message is NOT "waiting for some host".
2866 This is so "obvious" that I'm not sure why it wasn't done
2867 previously. Hope I haven't missed anything, but it can't do any
2868 harm, as the worst effect is to miss an optimization.
2869
2870 (ii) If, despite (i), such a delivery is accidentally attempted, the
2871 routing retry time is respected, so at least it doesn't keep
2872 hammering the server.

2887PH/35 The error "getsockname() failed: connection reset by peer" was being
2888 written to the panic log as well as the main log, but it isn't really

2890 removed the panic log writing for the ECONNRESET error when getsockname()
2891 fails.
2892
48c7f9e2
PH
2893PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2894 runs only) independently of the message's sender address. This meant
2895 that, if the 4xx error was in fact related to the sender, a different
2896 message to the same recipient with a different sender could confuse
4c04137d 2897 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2898 server, but other circumstances could also provoke similar problems.
2899 I have changed the default so that the retry time for these errors is now
2900 based a combination of the sender and recipient addresses. This change
2901 can be overridden by setting address_retry_include_sender=false in the
2902 smtp transport.

3170PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
3171 "Deny" causes Exim to reject the incoming connection with a 554 error.
3172 Unfortunately, if there is a major crisis, such as a disk failure,
3173 tcp-wrappers gives "deny", whereas what one would like would be some
3174 kind of temporary error. A kludge has been added to help with this.
3175 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3176 554 error is used if errno is still zero or contains ENOENT (which occurs
3177 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
3178 451 error is used.

3200PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
3201 folder from quota calculations, a direct delivery into this folder messed
3202 up the contents of the maildirsize file. This was because the regex was
3203 used only to exclude .Trash (or whatever) when the size of the mailbox
3204 was calculated. There was no check that a delivery was happening into an
3205 excluded directory. This bug has been fixed by ignoring all quota
3206 processing for deliveries into excluded directories.

3211Exim version 4.61
3212-----------------
3213
3214PH/01 The code for finding all the local interface addresses on a FreeBSD
3215 system running IPv6 was broken. This may well have applied to all BSD
3216 systems, as well as to others that have similar system calls. The broken
3217 code found IPv4 interfaces correctly, but gave incorrect values for the
3218 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
3219 that it would not match correctly against @[] and not recognize the IPv6
3220 addresses as local.

3229 lines in autoreplies, and the decoded form may well be syntactically
3230 invalid. However, $reply_address has leading white space removed, and all
3231 newlines turned into spaces so that the autoreply transport does not
3232 grumble.

3261 syntactically invalid From: or Reply-to: line, and a filter used this to
3262 generate an autoreply, and therefore failed to obtain an address for the
3263 autoreply, Exim could try to deliver to a non-existent relative file
