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.

34 add noisy ifdef guards to special-case this sillyness.

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/>.

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.

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.

243JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
244 TCP connections (such as for Spamd) unless the daemon successfully set
245 Fast Open mode on its listening sockets. This fixes breakage seen on
246 too-old kernels or those not configured for Fast Open, at the cost of
247 requiring both directions being enabled for TFO, and TFO never being used

266JH/16 Drop variables when they go out of scope. Memory management drops a whole

269 variables at a store-reset and panics on a dangling pointer; add code
270 explicitly nulling out all the variables discovered. Fixes one known

309JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
310 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
311 or even an in-clear connection were permitted. Now, if the host lookup
312 was dnssec and dane was requested then the host is only used if the
313 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
314 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
315 if one fails this test.
316 This means that a poorly-configured remote DNS will make it incommunicado;
317 but it protects against a DNS-interception attack on it.

1131TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1132
1133 When a queue runner is handling a message, Exim first routes the
1134 recipient addresses, during which it prunes them based on the retry
1135 hints database. After that it attempts to deliver the message to
1136 any remaining recipients. It then updates the hints database using
1137 the retry rules.
1138
1139 So if a recipient address works intermittently, it can get repeatedly
1140 deferred at routing time. The retry hints record remains fresh so the
1141 address never reaches the final cutoff time.
1142
1143 This is a fairly common occurrence when a user is bumping up against
1144 their storage quota. Exim had some logic in its local delivery code
1145 to deal with this. However it did not apply to per-recipient defers
1146 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1147
1ddeb334
TF
1148 This change adds a proper retry rule check during routing so that the
1149 final cutoff time is checked against the message's age. We only do
1150 this check if there is an address retry record and there is not a
1151 domain retry record; this implies that previous attempts to handle
1152 the address had the retry_use_local_parts option turned on. We use
1153 this as an approximation for the destination being like a local
1154 delivery, as in LMTP.
67bd1ab3
TF
1155
1156 I suspect this new check makes the old local delivery cutoff check
1157 redundant, but I have not verified this so I left the code in place.

1192 Server implementation by Todd Lyons, client by JH.

1197 the body content is received and before the acl_smtp_data ACL.

1479TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1480 lock up or crash if it happened to be inside a call to libc when it
1481 got a SIGUSR1 from exiwhat.
1482
1483 The SIGUSR1 handler appends the current process status to the process
1484 log which is later printed by exiwhat. It used to use the general
1485 purpose logging code to do this, but several functions it calls are
1486 not safe for signals.
1487
1488 The new output code in the SIGUSR1 handler is specific to the process
1489 log, and simple enough that it's easy to inspect for signal safety.
1490 Removing some special cases also simplifies the general logging code.
1491 Removing the spurious timestamps from the process log simplifies
1492 exiwhat.
1493
c99ce5c9
TF
1494TF/04 Improved ratelimit ACL condition.
1495
1496 The /noupdate option has been deprecated in favour of /readonly which
1497 has clearer semantics. The /leaky, /strict, and /readonly update modes
1498 are mutually exclusive. The update mode is no longer included in the
1499 database key; it just determines when the database is updated. (This
4c04137d 1500 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1501
1502 Exim now checks that the per_* options are used with an update mode that
1503 makes sense for the current ACL. For example, when Exim is processing a
1504 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1505 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1506 must specify per_mail/readonly. If you omit the update mode it defaults to
1507 /leaky where that makes sense (as before) or /readonly where required.
1508
1509 The /noupdate option is now undocumented but still supported for
1510 backwards compatibility. It is equivalent to /readonly except that in
1511 ACLs where /readonly is required you may specify /leaky/noupdate or
1512 /strict/noupdate which are treated the same as /readonly.
1513
1514 A useful new feature is the /count= option. This is a generalization
1515 of the per_byte option, so that you can measure the throughput of other
1516 aggregate values. For example, the per_byte option is now equivalent
1517 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1518
1519 The per_rcpt option has been generalized using the /count= mechanism
1520 (though it's more complicated than the per_byte equivalence). When it is
1521 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1522 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1523 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1524 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1525 Note that using per_rcpt with a non-readonly update mode in more than
1526 one ACL will cause the recipients to be double-counted. (The per_mail
1527 and per_byte options don't have this problem.)
1528
1529 The handling of very low rates has changed slightly. If the computed rate
1530 is less than the event's count (usually one) then this event is the first
1531 after a long gap. In this case the rate is set to the same as this event's
1532 count, so that the first message of a spam run is counted properly.
1533
1534 The major new feature is a mechanism for counting the rate of unique
1535 events. The new per_addr option counts the number of different
1536 recipients that someone has sent messages to in the last time period. It
1537 behaves like per_rcpt if all the recipient addresses are different, but
1538 duplicate recipient addresses do not increase the measured rate. Like
1539 the /count= option this is a general mechanism, so the per_addr option
1540 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1541 example, measure the rate that a client uses different sender addresses
1542 with the options per_mail/unique=$sender_address. There are further
1543 details in the main documentation.

2094 were called 'true' and it seems that C99 defines that as a reserved

2113-----------------
2114
2115PH/01 Another patch from the Sieve maintainer.
2116
6a3bceb1
PH
2117PH/02 When an IPv6 address is converted to a string for single-key lookup
2118 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2119 dots are used instead of colons so that keys in lsearch files need not
2120 contain colons. This was done some time before quoting was made available
2121 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2122 (notated using the quote facility) so as to distinguish them from IPv4
2123 keys. This meant that lookups for IP addresses in host lists did not work
2124 for iplsearch lookups.
2125
2126 This has been fixed by arranging for IPv6 addresses to be expressed with
2127 colons if the lookup type is iplsearch. This is not incompatible, because
2128 previously such lookups could never work.
2129
4c04137d 2130 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2131 ordinary lsearch keys. However, making the change in all cases is
2132 incompatible and would probably break a number of configurations.

MH
2137MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2138 conversion specification without a maximum field width, thereby enabling
2139 a rogue spamd server to cause a buffer overflow. While nobody in their
2140 right mind would setup Exim to query an untrusted spamd server, an
2141 attacker that gains access to a server running spamd could potentially
2142 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
2147MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2148 a directory entry by the name of the lookup key. Previously, if a
2149 symlink pointed to a non-existing file or a file in a directory that
2150 Exim lacked permissions to read, a lookup for a key matching that
2151 symlink would fail. Now it is enough that a matching directory entry
2152 exists, symlink or not. (Bugzilla 503.)

2229 if a client was not listed at all, or was listed with a value other than
2230 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
2231 the condition was not true (as it should be), so access was not denied.

PH
2335PH/29 SMTP synchronization checks are implemented when a command is read -
2336 there is a check that no more input is waiting when there shouldn't be
2337 any. However, for some commands, a delay in an ACL can mean that it is
2338 some time before the response is written. In this time, more input might
2339 arrive, invalidly. So now there are extra checks after an ACL has run for
2340 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2341 pipelining has not been advertised.

2356 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2357 was a macro that became an assignment, so it seemed to work. This has

2415 the response to the final '.' that terminates a message, but only in the
2416 case where the client has not sent further data following the '.'
2417 (unfortunately, this is allowed). However, in many cases there won't be
2418 any further data because there won't be any more messages to send. A call
2419 to select() can be used: if it shows that the input is "ready", there is
2420 either input waiting, or the socket has been closed. An attempt to read
2421 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2422 would have sent an OK response which the client would never have see.

2433PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2434 fixed by 4.65/MH/01 (is this a record?) are fixed:
2435
2436 (i) An empty string was always treated as zero by the numeric comparison
2437 operators. This behaviour has been restored.
2438
2439 (ii) It is documented that the numeric comparison operators always treat
2440 their arguments as decimal numbers. This was broken in that numbers
2441 starting with 0 were being interpreted as octal.
2442
2443 While fixing these problems I realized that there was another issue that
2444 hadn't been noticed. Values of message_size_limit (both the global option
2445 and the transport option) were treated as octal if they started with 0.
2446 The documentation was vague. These values are now always treated as
2447 decimal, and I will make that clear in the documentation.

2464 large number of recipients for a single message is ridiculous
2465 (performance will be very, very poor), I have chosen to impose a limit
2466 rather than extend the field.

PH
2491PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2492 callout verification, Exim cached a "reject" for the entire domain. This
2493 is correct for most verifications, but it is not correct for a recipient
2494 verification with use_sender or use_postmaster set, because in that case
2495 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2496 case of MAIL FROM:<> rejection from other early rejections (e.g.
2497 rejection of HELO). When verifying a recipient using a non-null MAIL
2498 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2499 Whatever the result of the callout, the value of the domain cache is
2500 left unchanged (for any other kind of callout, getting as far as trying
2501 RCPT means that the domain itself is ok).

2535PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2537 probably the interface on which it is arriving) and not to the outgoing
2538 callout (which could be using a different interface). This has been
2539 changed to use the value of the helo_data option from the smtp transport
2540 instead - this is what is used when a message is actually being sent. If
2541 there is no remote transport (possible with a router that sets up host
2542 addresses), $smtp_active_hostname is used.

7befa435 2545 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2546 (a) The code assumed that strncpy() returns a negative number on buffer
2547 overflow, which isn't the case. Replaced with Exim's string_format()
2548 function.
2549 (b) There were several signed/unsigned issues. I just did the minimum
2550 hacking in of casts. There is scope for a larger refactoring.
2551 (c) The code used strcasecmp() which is not a standard C function.
2552 Replaced with Exim's strcmpic() function.
2553 (d) The code set only $1; it now sets $auth1 as well.
2554 (e) A simple test gave the error "authentication client didn't specify
2555 service in request". It would seem that Dovecot has changed its
2556 interface. Fortunately there's a specification; I followed it and
2557 changed what the client sends and it appears to be working now.

2563 address A is aliased to B and C, where B exists and C does not. Without
2564 -v the output is "A verified" because verification stops after a
2565 successful redirection if more than one address is generated. However,
2566 with -v the child addresses are also verified. Exim was outputting "A
2567 failed to verify" and then showing the successful verification for C,
2568 with its parentage. It now outputs "B failed to verify", showing B's
2569 parentage before showing the successful verification of C.

2574
322050c2
PH
2575PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2576 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2577 they consult the DNS. I had assumed they would set it the way they
2578 wanted; and indeed my experiments on Linux seem to show that in some
2579 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2580 To be on the safe side, however, I have now made the interface to
2581 host_find_byname() similar to host_find_bydns(), with an argument
2582 containing the DNS resolver options. The host_find_byname() function now
2583 sets these options at its start, just as host_find_bydns() does. The smtp
2584 transport options dns_qualify_single and dns_search_parents are passed to
2585 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2586 of host_find_byname() use the default settings of RES_DEFNAMES
2587 (qualify_single) but not RES_DNSRCH (search_parents).

2590 spool_read_header() do less string testing, by means of a preliminary
2591 switch on the second character of optional "-foo" lines. (This is
2592 overdue, caused by the large number of possibilities that now exist.
2593 Originally there were few.) While I was there, I also converted the
2594 str(n)cmp tests so they don't re-test the leading "-" and the first
2595 character, in the hope this might squeeze out yet more improvement.

2597PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2598 flag allowing group syntax was set by the header_syntax check but not
2599 turned off, possible causing trouble later; (2) The flag was not being
2600 set at all for the header_verify test, causing "group"-style headers to
2601 be rejected. I have now set it in this case, and also caused header_
2602 verify to ignore an empty address taken from a group. While doing this, I
2603 came across some other cases where the code for allowing group syntax
2604 while scanning a header line wasn't quite right (mostly, not resetting
2605 the flag correctly in the right place). These bugs could have caused
2606 trouble for malformed header lines. I hope it is now all correct.

PH
2608PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

PH
2614PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2615 feature that was used to support insecure browsers during the U.S. crypto
2616 embargo. It requires special client support, and Exim is probably the
2617 only MTA that supported it -- and would never use it because real RSA is
2618 always available. This code has been removed, because it had the bad
2619 effect of slowing Exim down by computing (never used) parameters for the
2620 RSA_EXPORT functionality.

2626 if the connection is using TLS or if the remote IP is the same as the
2627 local IP, and the "valid-client-cert option" if a client certificate has
2628 been verified.

2659
2660PH/30 Exim was sometimes attempting to deliver messages that had suffered
2661 address errors (4xx response to RCPT) over the same connection as other
2662 messages routed to the same hosts. Such deliveries are always "forced",
2663 so retry times are not inspected. This resulted in far too many retries
2664 for the affected addresses. The effect occurred only when there were more
2665 hosts than the hosts_max_try setting in the smtp transport when it had
2666 the 4xx errors. Those hosts that it had tried were not added to the list
2667 of hosts for which the message was waiting, so if all were tried, there
2668 was no problem. Two fixes have been applied:
2669
2670 (i) If there are any address or message errors in an SMTP delivery, none
2671 of the hosts (tried or untried) are now added to the list of hosts
2672 for which the message is waiting, so the message should not be a
2673 candidate for sending over the same connection that was used for a
2674 successful delivery of some other message. This seems entirely
2675 reasonable: after all the message is NOT "waiting for some host".
2676 This is so "obvious" that I'm not sure why it wasn't done
2677 previously. Hope I haven't missed anything, but it can't do any
2678 harm, as the worst effect is to miss an optimization.
2679
2680 (ii) If, despite (i), such a delivery is accidentally attempted, the
2681 routing retry time is respected, so at least it doesn't keep
2682 hammering the server.

2697PH/35 The error "getsockname() failed: connection reset by peer" was being
2698 written to the panic log as well as the main log, but it isn't really

2700 removed the panic log writing for the ECONNRESET error when getsockname()

PH
2703PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2704 runs only) independently of the message's sender address. This meant
2705 that, if the 4xx error was in fact related to the sender, a different
2706 message to the same recipient with a different sender could confuse
4c04137d 2707 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2708 server, but other circumstances could also provoke similar problems.
2709 I have changed the default so that the retry time for these errors is now
2710 based a combination of the sender and recipient addresses. This change
2711 can be overridden by setting address_retry_include_sender=false in the
2712 smtp transport.

2983 tcp-wrappers gives "deny", whereas what one would like would be some
2984 kind of temporary error. A kludge has been added to help with this.
2985 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2986 554 error is used if errno is still zero or contains ENOENT (which occurs
2987 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

3088 literals of the form [IPV4:n.n.n.n] are now always recognized.

3090PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3091 used if the router is not running as root, for example, when verifying at
3092 ACL time, or when using -bh. The debugging output from this situation was
3093 non-existent - all you got was a failure to exec. I have made two
3094 changes:
3095
3096 (a) Failures to set uid/gid, the current directory, or a process leader
3097 in a subprocess such as that created by queryprogram now generate
4c04137d 3098 suitable debugging output when -d is set.

3099
3100 (b) The queryprogram router detects when it is not running as root,
3101 outputs suitable debugging information if -d is set, and then runs
3102 the subprocess without attempting to change uid/gid.

3107PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3108 additional section of a DNS packet that returns MX or SRV records.
3109 Instead, it always explicitly searches for A/AAAA records. This avoids
3110 major problems that occur when a DNS server includes only records of one
3111 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3112 fixed another bug: if SRV records were looked up and the corresponding
3113 address records were *not* found in the additional section, the port
3114 values from the SRV records were lost.

3116PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

3120PH/18 If quota_warn_message contains a From: header, Exim now refrains from

3124PH/19 When calculating a retry time, Exim used to measure the "time since
3125 failure" by looking at the "first failed" field in the retry record. Now
3126 it does not use this if it is later than than the arrival time of the
3127 message. Instead it uses the arrival time. This makes for better
3128 behaviour in cases where some deliveries succeed, thus re-setting the
3129 "first failed" field. An example is a quota failure for a huge message
3130 when small messages continue to be delivered. Without this change, the
3131 "time since failure" will always be short, possible causing more frequent
3132 delivery attempts for the huge message than are intended.

3229PH/42 The content-scanning code uses fopen() to create files in which to put
3230 message data. Previously it was not paying any attention to the mode of
3231 the files. Exim runs with umask(0) because the rest of the code creates
3232 files with open(), and sets the required mode explicitly. Thus, these
3233 files were ending up world-writeable. This was not a big issue, because,
3234 being within the spool directory, they were not world-accessible. I have
3235 created a function called modefopen, which takes an additional mode
3236 argument. It sets umask(777), creates the file, chmods it to the required
3237 mode, then resets the umask. All the relevant calls to fopen() in the
3238 content scanning code have been changed to use this function.

3247 challenges are checked to ensure they are valid base64 strings. By
3248 default, the authentication attempt is cancelled if an invalid string is
3249 received. Setting client_ignore_invalid_base64 true ignores these errors.
3250 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3251 they are received. Thus, the responses can be made to depend on the
3252 challenges. If an invalid string is ignored, an empty string is placed in
3253 the variable.
