9-----------------
10
11JH/01 Rework error string handling in TLS interface so that the caller in
12 more cases is responsible for logging. This permits library-sourced
13 string to be attached to addresses during delivery, and collapses
14 pairs of long lines into single ones.
15

PP
16PP/01 Allow PKG_CONFIG_PATH to be set in Local/Makefile and use it correctly
17 during configuration. Wildcards are allowed and expanded.

JH
19JH/02 Rework error string handling in DKIM to pass more info back to callers.
20 This permits better logging.
21
875512a3
JH
22JH/03 Rework the transport continued-connection mechanism: when TLS is active,
23 do not close it down and have the child transport start it up again on
24 the passed-on TCP connection. Instead, proxy the child (and any
25 subsequent ones) for TLS via a unix-domain socket channel. Logging is
26 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 27 Certificate or OCSP information. TLS cipher information is still logged.

29JH/04 Shorten the log line for daemon startup by collapsing adjacent sets of
30 identical IP addresses on different listening ports. Will also affect
31 "exiwhat" output.

33PP/02 Bug 2070: uClibc defines __GLIBC__ without providing glibc headers;
34 add noisy ifdef guards to special-case this sillyness.
35 Patch from Bernd Kuhls.
36

JH
37JH/05 Tighten up the checking in isip4 (et al): dotted-quad components larger
38 than 255 are no longer allowed.
39
7006ee24
JH
40JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
41 Disable the session-cache too, which might reduce our load. Since we
42 currrectly use a new context for every connection, both as server and
43 client, there is no benefit for these.
44 GnuTLS appears to not support tickets server-side by default (we don't
45 call gnutls_session_ticket_enable_server()) but client side is enabled
46 by default on recent versions (3.1.3 +) unless the PFS priority string
47 is used (3.2.4 +).

50 <https://reproducible-builds.org/specs/source-date-epoch/>.
51
4c2471ca
JH
52JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
53 the check for any unsuccessful recipients did not notice the limit, and
54 erroneously found still-pending ones.
55
4e910c01
JH
56JH/08 Pipeline CHUNKING command and data together, on kernels that support
57 MSG_MORE. Only in-clear (not on TLS connections).
58
42055a33
JH
59JH/09 Avoid using a temporary file during transport using dkim. Unless a
60 transport-filter is involved we can buffer the headers in memory for
61 creating the signature, and read the spool data file once for the
62 signature and again for transmission.
63
eeb35890
JH
64JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
65 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 66 mode. Now, it's been long enough. Add support for FreeBSD also.

JH
68JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
69 case where the routing stage had gathered several addresses to send to
70 a host before calling the transport for the first, we previously failed
71 to close down TLS in the old transport process before passing the TCP
72 connection to the new process. The new one sent a STARTTLS command
73 which naturally failed, giving a failed delivery and bloating the retry
74 database. Investigation and fix prototype from Wolfgang Breyha.
75
40525d07
JH
76JH/12 Fix check on SMTP command input synchronisation. Previously there were
77 false-negatives in the check that the sender had not preempted a response
78 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 79 awareness of the SMTP input buffering.
40525d07 80
f33875c3
PP
81PP/04 Add commandline_checks_require_admin option.
82 Exim drops privileges sanely, various checks such as -be aren't a
83 security problem, as long as you trust local users with access to their
84 own account. When invoked by services which pass untrusted data to
85 Exim, this might be an issue. Set this option in main configuration
86 AND make fixes to the calling application, such as using `--` to stop
87 processing options.
88
a5ffa9b4
JH
89JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
90 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
91 responses to those, into a single TLS record each way (this usually means
92 a single packet). As a side issue, smtp_enforce_sync now works on TLS
93 connections.

PP
95PP/05 OpenSSL/1.1: use DH_bits() for more accurate DH param sizes. This
96 affects you only if you're dancing at the edge of the param size limits.
97 If you are, and this message makes sense to you, then: raise the
98 configured limit or use OpenSSL 1.1. Nothing we can do for older
99 versions.

102 cmdline element to get the documented default one. Previously it was
103 inaccessible.

106 are unsuable for non-message-specific reasons - eg. connection timeout,

126JH/19 Bug 2141: Use the full-complex API for Berkeley DB rather than the legacy-
127 compatible one, to avoid the (poorly documented) possibility of a config
128 file in the working directory redirecting the DB files, possibly correpting
02745400 129 some existing file. CVE-2017-10140 assigned for BDB.

209 It seems that HAProxy sends the Proxy Protocol information in clear and

211
212JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
213 TCP connections (such as for Spamd) unless the daemon successfully set
214 Fast Open mode on its listening sockets. This fixes breakage seen on
215 too-old kernels or those not configured for Fast Open, at the cost of
216 requiring both directions being enabled for TFO, and TFO never being used
217 by non-daemon-related Exim processes.

235JH/16 Drop variables when they go out of scope. Memory management drops a whole

239 explicitly nulling out all the variables discovered. Fixes one known

JH
278JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
279 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
280 or even an in-clear connection were permitted. Now, if the host lookup
281 was dnssec and dane was requested then the host is only used if the
282 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
283 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
284 if one fails this test.
285 This means that a poorly-configured remote DNS will make it incommunicado;
286 but it protects against a DNS-interception attack on it.

1100TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1101
1102 When a queue runner is handling a message, Exim first routes the
1103 recipient addresses, during which it prunes them based on the retry
1104 hints database. After that it attempts to deliver the message to
1105 any remaining recipients. It then updates the hints database using
1106 the retry rules.
1107
1108 So if a recipient address works intermittently, it can get repeatedly
1109 deferred at routing time. The retry hints record remains fresh so the
1110 address never reaches the final cutoff time.
1111
1112 This is a fairly common occurrence when a user is bumping up against
1113 their storage quota. Exim had some logic in its local delivery code
1114 to deal with this. However it did not apply to per-recipient defers
1115 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1116
1ddeb334
TF
1117 This change adds a proper retry rule check during routing so that the
1118 final cutoff time is checked against the message's age. We only do
1119 this check if there is an address retry record and there is not a
1120 domain retry record; this implies that previous attempts to handle
1121 the address had the retry_use_local_parts option turned on. We use
1122 this as an approximation for the destination being like a local
1123 delivery, as in LMTP.
67bd1ab3
TF
1124
1125 I suspect this new check makes the old local delivery cutoff check
1126 redundant, but I have not verified this so I left the code in place.

1448TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1449 lock up or crash if it happened to be inside a call to libc when it
1450 got a SIGUSR1 from exiwhat.
1451
1452 The SIGUSR1 handler appends the current process status to the process
1453 log which is later printed by exiwhat. It used to use the general
1454 purpose logging code to do this, but several functions it calls are
1455 not safe for signals.
1456
1457 The new output code in the SIGUSR1 handler is specific to the process
1458 log, and simple enough that it's easy to inspect for signal safety.
1459 Removing some special cases also simplifies the general logging code.
1460 Removing the spurious timestamps from the process log simplifies
1461 exiwhat.
1462
c99ce5c9
TF
1463TF/04 Improved ratelimit ACL condition.
1464
1465 The /noupdate option has been deprecated in favour of /readonly which
1466 has clearer semantics. The /leaky, /strict, and /readonly update modes
1467 are mutually exclusive. The update mode is no longer included in the
1468 database key; it just determines when the database is updated. (This
4c04137d 1469 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1470
1471 Exim now checks that the per_* options are used with an update mode that
1472 makes sense for the current ACL. For example, when Exim is processing a
1473 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1474 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1475 must specify per_mail/readonly. If you omit the update mode it defaults to
1476 /leaky where that makes sense (as before) or /readonly where required.
1477
1478 The /noupdate option is now undocumented but still supported for
1479 backwards compatibility. It is equivalent to /readonly except that in
1480 ACLs where /readonly is required you may specify /leaky/noupdate or
1481 /strict/noupdate which are treated the same as /readonly.
1482
1483 A useful new feature is the /count= option. This is a generalization
1484 of the per_byte option, so that you can measure the throughput of other
1485 aggregate values. For example, the per_byte option is now equivalent
1486 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1487
1488 The per_rcpt option has been generalized using the /count= mechanism
1489 (though it's more complicated than the per_byte equivalence). When it is
1490 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1491 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1492 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1493 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1494 Note that using per_rcpt with a non-readonly update mode in more than
1495 one ACL will cause the recipients to be double-counted. (The per_mail
1496 and per_byte options don't have this problem.)
1497
1498 The handling of very low rates has changed slightly. If the computed rate
1499 is less than the event's count (usually one) then this event is the first
1500 after a long gap. In this case the rate is set to the same as this event's
1501 count, so that the first message of a spam run is counted properly.
1502
1503 The major new feature is a mechanism for counting the rate of unique
1504 events. The new per_addr option counts the number of different
1505 recipients that someone has sent messages to in the last time period. It
1506 behaves like per_rcpt if all the recipient addresses are different, but
1507 duplicate recipient addresses do not increase the measured rate. Like
1508 the /count= option this is a general mechanism, so the per_addr option
1509 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1510 example, measure the rate that a client uses different sender addresses
1511 with the options per_mail/unique=$sender_address. There are further
1512 details in the main documentation.

2063 were called 'true' and it seems that C99 defines that as a reserved

2081Exim version 4.68
2082-----------------
2083
2084PH/01 Another patch from the Sieve maintainer.
2085
6a3bceb1
PH
2086PH/02 When an IPv6 address is converted to a string for single-key lookup
2087 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2088 dots are used instead of colons so that keys in lsearch files need not
2089 contain colons. This was done some time before quoting was made available
2090 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2091 (notated using the quote facility) so as to distinguish them from IPv4
2092 keys. This meant that lookups for IP addresses in host lists did not work
2093 for iplsearch lookups.
2094
2095 This has been fixed by arranging for IPv6 addresses to be expressed with
2096 colons if the lookup type is iplsearch. This is not incompatible, because
2097 previously such lookups could never work.
2098
4c04137d 2099 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2100 ordinary lsearch keys. However, making the change in all cases is
2101 incompatible and would probably break a number of configurations.
2102

TK
2103TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
2104 version.
2105
0806a9c5
MH
2106MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2107 conversion specification without a maximum field width, thereby enabling
2108 a rogue spamd server to cause a buffer overflow. While nobody in their
2109 right mind would setup Exim to query an untrusted spamd server, an
2110 attacker that gains access to a server running spamd could potentially
2111 exploit this vulnerability to run arbitrary code as the Exim user.

2113TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
2114 $primary_hostname instead of what libspf2 thinks the hosts name is.
2115
0f2cbd1b
MH
2116MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2117 a directory entry by the name of the lookup key. Previously, if a
2118 symlink pointed to a non-existing file or a file in a directory that
2119 Exim lacked permissions to read, a lookup for a key matching that
2120 symlink would fail. Now it is enough that a matching directory entry
2121 exists, symlink or not. (Bugzilla 503.)

2194PH/02 In an ACL statement such as

2197
2198 if a client was not listed at all, or was listed with a value other than
2199 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
2200 the condition was not true (as it should be), so access was not denied.
2201 The bug was that the ! inversion was incorrectly passed on to the second
2202 item. This has been fixed.

2303
a14e5636
PH
2304PH/29 SMTP synchronization checks are implemented when a command is read -
2305 there is a check that no more input is waiting when there shouldn't be
2306 any. However, for some commands, a delay in an ACL can mean that it is
2307 some time before the response is written. In this time, more input might
2308 arrive, invalidly. So now there are extra checks after an ACL has run for

2325 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2326 was a macro that became an assignment, so it seemed to work. This has

2384 the response to the final '.' that terminates a message, but only in the
2385 case where the client has not sent further data following the '.'
2386 (unfortunately, this is allowed). However, in many cases there won't be
2387 any further data because there won't be any more messages to send. A call
2388 to select() can be used: if it shows that the input is "ready", there is
2389 either input waiting, or the socket has been closed. An attempt to read
2390 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2391 would have sent an OK response which the client would never have see.

2402PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2403 fixed by 4.65/MH/01 (is this a record?) are fixed:
2404
2405 (i) An empty string was always treated as zero by the numeric comparison
2406 operators. This behaviour has been restored.
2407
2408 (ii) It is documented that the numeric comparison operators always treat
2409 their arguments as decimal numbers. This was broken in that numbers
2410 starting with 0 were being interpreted as octal.
2411
2412 While fixing these problems I realized that there was another issue that
2413 hadn't been noticed. Values of message_size_limit (both the global option
2414 and the transport option) were treated as octal if they started with 0.
2415 The documentation was vague. These values are now always treated as
2416 decimal, and I will make that clear in the documentation.

2433 large number of recipients for a single message is ridiculous
2434 (performance will be very, very poor), I have chosen to impose a limit

PH
2460PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2461 callout verification, Exim cached a "reject" for the entire domain. This
2462 is correct for most verifications, but it is not correct for a recipient
2463 verification with use_sender or use_postmaster set, because in that case
2464 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2465 case of MAIL FROM:<> rejection from other early rejections (e.g.
2466 rejection of HELO). When verifying a recipient using a non-null MAIL
2467 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2468 Whatever the result of the callout, the value of the domain cache is
2469 left unchanged (for any other kind of callout, getting as far as trying
2470 RCPT means that the domain itself is ok).

2506 probably the interface on which it is arriving) and not to the outgoing
2507 callout (which could be using a different interface). This has been
2508 changed to use the value of the helo_data option from the smtp transport
2509 instead - this is what is used when a message is actually being sent. If
2510 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
2515 (a) The code assumed that strncpy() returns a negative number on buffer
2516 overflow, which isn't the case. Replaced with Exim's string_format()
2517 function.
2518 (b) There were several signed/unsigned issues. I just did the minimum
2519 hacking in of casts. There is scope for a larger refactoring.
2520 (c) The code used strcasecmp() which is not a standard C function.
2521 Replaced with Exim's strcmpic() function.
2522 (d) The code set only $1; it now sets $auth1 as well.
2523 (e) A simple test gave the error "authentication client didn't specify
2524 service in request". It would seem that Dovecot has changed its
2525 interface. Fortunately there's a specification; I followed it and
2526 changed what the client sends and it appears to be working now.

2533 -v the output is "A verified" because verification stops after a
2534 successful redirection if more than one address is generated. However,
2535 with -v the child addresses are also verified. Exim was outputting "A
2536 failed to verify" and then showing the successful verification for C,
2537 with its parentage. It now outputs "B failed to verify", showing B's
2538 parentage before showing the successful verification of C.

322050c2
PH
2544PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2545 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2546 they consult the DNS. I had assumed they would set it the way they
2547 wanted; and indeed my experiments on Linux seem to show that in some
2548 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2549 To be on the safe side, however, I have now made the interface to
2550 host_find_byname() similar to host_find_bydns(), with an argument
2551 containing the DNS resolver options. The host_find_byname() function now
2552 sets these options at its start, just as host_find_bydns() does. The smtp
2553 transport options dns_qualify_single and dns_search_parents are passed to
2554 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2555 of host_find_byname() use the default settings of RES_DEFNAMES
2556 (qualify_single) but not RES_DNSRCH (search_parents).

2559 spool_read_header() do less string testing, by means of a preliminary
2560 switch on the second character of optional "-foo" lines. (This is
2561 overdue, caused by the large number of possibilities that now exist.
2562 Originally there were few.) While I was there, I also converted the
2563 str(n)cmp tests so they don't re-test the leading "-" and the first
2564 character, in the hope this might squeeze out yet more improvement.

2566PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2567 flag allowing group syntax was set by the header_syntax check but not
2568 turned off, possible causing trouble later; (2) The flag was not being
2569 set at all for the header_verify test, causing "group"-style headers to
2570 be rejected. I have now set it in this case, and also caused header_
2571 verify to ignore an empty address taken from a group. While doing this, I
2572 came across some other cases where the code for allowing group syntax
2573 while scanning a header line wasn't quite right (mostly, not resetting
2574 the flag correctly in the right place). These bugs could have caused
2575 trouble for malformed header lines. I hope it is now all correct.

2577PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

PH
2583PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2584 feature that was used to support insecure browsers during the U.S. crypto
2585 embargo. It requires special client support, and Exim is probably the
2586 only MTA that supported it -- and would never use it because real RSA is
2587 always available. This code has been removed, because it had the bad
2588 effect of slowing Exim down by computing (never used) parameters for the
2589 RSA_EXPORT functionality.

2628
2629PH/30 Exim was sometimes attempting to deliver messages that had suffered
2630 address errors (4xx response to RCPT) over the same connection as other
2631 messages routed to the same hosts. Such deliveries are always "forced",
2632 so retry times are not inspected. This resulted in far too many retries
2633 for the affected addresses. The effect occurred only when there were more
2634 hosts than the hosts_max_try setting in the smtp transport when it had
2635 the 4xx errors. Those hosts that it had tried were not added to the list
2636 of hosts for which the message was waiting, so if all were tried, there
2637 was no problem. Two fixes have been applied:
2638
2639 (i) If there are any address or message errors in an SMTP delivery, none
2640 of the hosts (tried or untried) are now added to the list of hosts
2641 for which the message is waiting, so the message should not be a
2642 candidate for sending over the same connection that was used for a
2643 successful delivery of some other message. This seems entirely
2644 reasonable: after all the message is NOT "waiting for some host".
2645 This is so "obvious" that I'm not sure why it wasn't done
2646 previously. Hope I haven't missed anything, but it can't do any
2647 harm, as the worst effect is to miss an optimization.
2648
2649 (ii) If, despite (i), such a delivery is accidentally attempted, the
2650 routing retry time is respected, so at least it doesn't keep
2651 hammering the server.

48c7f9e2
PH
2672PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue

2674 that, if the 4xx error was in fact related to the sender, a different
2675 message to the same recipient with a different sender could confuse
4c04137d 2676 things. In particular, this can happen when sending to a greylisting

2677 server, but other circumstances could also provoke similar problems.
2678 I have changed the default so that the retry time for these errors is now

2952 tcp-wrappers gives "deny", whereas what one would like would be some
2953 kind of temporary error. A kludge has been added to help with this.
2954 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2955 554 error is used if errno is still zero or contains ENOENT (which occurs
2956 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

3042 autoreply, Exim could try to deliver to a non-existent relative file

3079 major problems that occur when a DNS server includes only records of one
3080 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3081 fixed another bug: if SRV records were looked up and the corresponding
3082 address records were *not* found in the additional section, the port

3085PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

3093PH/19 When calculating a retry time, Exim used to measure the "time since
3094 failure" by looking at the "first failed" field in the retry record. Now
3095 it does not use this if it is later than than the arrival time of the
3096 message. Instead it uses the arrival time. This makes for better
3097 behaviour in cases where some deliveries succeed, thus re-setting the
3098 "first failed" field. An example is a quota failure for a huge message
3099 when small messages continue to be delivered. Without this change, the
3100 "time since failure" will always be short, possible causing more frequent
3101 delivery attempts for the huge message than are intended.

PH
3198PH/42 The content-scanning code uses fopen() to create files in which to put
3199 message data. Previously it was not paying any attention to the mode of
3200 the files. Exim runs with umask(0) because the rest of the code creates
3201 files with open(), and sets the required mode explicitly. Thus, these
3202 files were ending up world-writeable. This was not a big issue, because,
3203 being within the spool directory, they were not world-accessible. I have
3204 created a function called modefopen, which takes an additional mode
3205 argument. It sets umask(777), creates the file, chmods it to the required
3206 mode, then resets the umask. All the relevant calls to fopen() in the
3207 content scanning code have been changed to use this function.

3215PH/45 When the plaintext authenticator is running as a client, the server's
3216 challenges are checked to ensure they are valid base64 strings. By
3217 default, the authentication attempt is cancelled if an invalid string is
3218 received. Setting client_ignore_invalid_base64 true ignores these errors.
3219 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3220 they are received. Thus, the responses can be made to depend on the
3221 challenges. If an invalid string is ignored, an empty string is placed in
3222 the variable.

3236 of files (along with the size), even though it did not need this
3237 information. It now does the scan only if it needs to find either the
3238 size of the count of files.

3242PH/52 Two bugs concerned with error handling when the smtp transport is
3243 used in LMTP mode:
3244
3245 (i) Exim was not creating retry information for temporary errors given
3246 for individual recipients after the DATA command when the smtp transport
3247 was used in LMTP mode. This meant that they could be retried too
3248 frequently, and not timed out correctly.
3249
3250 (ii) Exim was setting the flag that allows error details to be returned
3251 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3252 recipients that were returned after the DATA command.
3253
3254PH/53 This is related to PH/52, but is more general: for any failing address,
3255 when detailed error information was permitted to be returned to the
3256 sender, but the error was temporary, then after the final timeout, only
3257 "retry timeout exceeded" was returned. Now it returns the full error as
3258 well as "retry timeout exceeded".
