related applications. Previously an "H" was used where available info
says that "M" should be, so change to match.
+JH/02 Bug 2587: Fix pam expansion condition. Tainted values are commonly used
+ as arguments, so an implementation trying to copy these into a local
+ buffer was taking a taint-enforcement trap. Fix by using dynamically
+ created buffers. Similar fix for radius expansion condition.
+
+JH/03 Bug 2586: Fix listcount expansion operator. Using tainted arguments is
+ reasonable, eg. to count headers. Fix by using dynamically created
+ buffers rather than a local. Do similar fixes for ACL actions "dcc",
+ "log_reject_target", "malware" and "spam"; the arguments are expanded
+ so could be handling tainted values.
+
+JH/04 Bug 2590: Fix -bi (newaliases). A previous code rearrangement had
+ broken the (no-op) support for this sendmail command. Restore it
+ to doing nothing, silently, and returning good status.
+
+JH/05 Bug 2593: Fix "vacation" in Exim filter. Previously, when a "once"
+ record path was given (or the default used) without a leading directory
+ path, an error occurred on trying to open it. Use the transport's working
+ directory.
+
+JH/06 Bug 2594: Change the name used for certificate name checks in the smtp
+ transport. Previously it was the name on the DNS A-record; use instead
+ the head of the CNAME chain leading there (if there is one). This seems
+ to align better with RFC 6125.
+
+JH/07 Bug 2597: Fix a resource leak. Using a lookup in obtaining a value for
+ smtp_accept_max_per_host allocated resources which were not released
+ when the limit was exceeded. This eventually crashed the daemon. Fix
+ by adding a relase action in that path.
+
+JH/08 Bug 2598: Fix verify ACL condition. The options for the condition are
+ expanded; previously using tainted values was rejected. Fix by using
+ dynamically-created buffers.
+
+JH/09 Relax restrictions on ACL verify condition needing access to message
+ headers. Previously they were only permitted in data and non-smtp ACLs;
+ permit also mime, dkim, prdr quit and notquit. Applies to header-syntax,
+ not_blind, header_sender and header_names_ascii verification.
+
+JH/10 Bug 2603: Fix coding of string copying to only evaluate arguments once.
+ Previously a macro used one argument twice; when called with the
+ argument as an expression having side-effects, incorrect operation
+ resulted. Use an inlineable function.
+
+JH/11 Bug 2604: Fix request to cutthrough-deliver when a connection is already
+ held open for a verify callout. Previously this wan not accounted for
+ and a corrupt onward SMTP conversation resulted.
+
+JH/12 Bug 2607: Fix the ${srs_encode } expansion to handle quoted local_parts.
+ Previously they were embedded naively in the constructed address; when
+ needed, strip the quoting and quote the entire local_part.
+ Also make the inbound_srs expansion condition handle quoting.
+
+JH/13 Fix dsearch "subdir" filter to ignore ".". Previously only ".." was
+ excluded, not matching the documentation.
+
+JH/14 Bug 2606: Fix a segfault in sqlite lookups. When no, or a bad, filename
+ was given for the sqlite_dbfile a trap resulted.
+
+JH/15 Bug 2620: Fix "spam" ACL condition. Previously, tainted values for the
+ "name" argument resulted in a trap. There is no reason to disallow such;
+ this was a coding error.
+
+JH/16 Bug 2615: Fix pause during message reception, on systems that have been
+ suspended/resumed. The Linux CLOCK_MONOTONIC does not account for time
+ spent suspended, ignoring the Posix definition. Previously we assumed
+ it did and a constant offset from real time could be used as a correction.
+ Change to using the same clock source for the start-of-message and the
+ post-message next-tick-wait. Also change to using CLOCK_BOOTTIME if it
+ exists, just to get a clock slightly more aligned to reality.
+
+JH/17 Bug 2295: Fix DKIM signing to always semicolon-terminate. Although the
+ RFC says it is optional some validators care. The missing char was not
+ intended but triggered by a line-wrap alignement. Discovery and fix by
+ Guillaume Outters, hacked on by JH.
+
+JH/18 Bug 2617: Fix a taint trap in parse_fix_phrase(). Previously when the
+ name being quoted was tainted a trap would be taken. Fix by using
+ dynamicaly created buffers. The routine could have been called by a
+ rewrite with the "h" flag, by using the "-F" command-line option, or
+ by using a "name=" option on a control=submission ACL modifier.
+
+JH/19 SPF: change the Authentication-Results expansion component to give
+ smtp.helo when the sender domain is empty. Previously it gave
+ "smtp.mailfrom=<>"
+
+JH/20 Bug 2631: ACL dnslist conditions now ignore and log any lookups returns
+ not in 127.0.0.0/8 to help in spotting list domains taken over by a
+ domain-parking registrar.
+
+JH/21 Bug 2630: Fix eol-replacement string for the ${readsocket } expansion.
+ Previously when a whitespace character was specified it was not inserted
+ after removing the newline.
+
+JH/22 Bug 2265: Force SNI usage for smtp transport DANE'd connections, to be
+ the domain part of the recipient address. This overrides any tls_sni
+ option set, which was previously used.
+
+JH/23 Logging: with the +tls_sni log_selector, do not wrap the received SNI
+ in quotes.
+
+JH/24 Bug 2634: Fix a taint trap seen on NetBSD: the testing coded for
+ is_tainted() had an off-by-one error in the overenthusiastic direction.
+ Find and fix by Gavan. Although NetBSD is not a supported platform for
+ 4.94 this bug could affect other platforms.
+
+PP/01 Fix default prime selection to be consistent.
+ One path used ike23 still, instead of exim.dev.20160529.3; now both
+ execution flows will use the same DH primes (currently
+ exim.dev.20160529.3).
+
+JH/25 OpenSSL: Fix back-compatibility behaviour surrounding tls_certificates
+ option in smtp transport, to match the documentation. Previously
+ verification was not being done in some cases where it should have been.
+
+JH/26 Bug 2646: fix a memory usage issue in ldap lookups. Previously, when more
+ than one server was defined and depending on the platform memory layout
+ details, an internal consistency trap could be hit while walking the list
+ of servers.
+
+JH/27 Bug 2648: fix the passing of an authenticator public-name through spool
+ files. The value is used by the authresults expansion item. Previously
+ if this was used in a router or transport, a crash could result.
+
+JH/28 Fix spurious logging of select error. Some platforms, notably FreeBSD,
+ have a sufficient incidence of EINTR returns from select that an
+ interaction with other operations done by the main daemon loop exposed
+ a bug in the error-handling. This was benign apart from the log
+ messages.
+
+JH/29 Bug 2675: add outgoing-interface I= element to deferred "==" log lines,
+ for consistency with delivered "=>" and failed "**" lines. While we're
+ there, handle PRX and TFO.
+
+JH/30 Bug 2677: fix matching of long addresses. Since 4.93 a limit of 256 was
+ applied. This resulted, if any header-line rewrite rules were configured,
+ in a panic-log trigerrable by sending a message with a long address in
+ a header. Fix by increaing the arbitrary limit to larger than a single
+ (dewrapped) 5322 header line maximum size.
+
+JH/31 The ESMTP option name advertised for the SUPPORT_EARLY_PIPE build option
+ is changed from X_PIPE_CONNECT to PIPE_CONNECT. This is in line with
+ RFC 6648 which deprecates X- options in protocols as a general practice.
+ Changeover between the implementations is handled by the mechanisms
+ alrready coded.
+
+JH/32 Bug 2599: fix delay of delivery to a local address where there is also
+ a remote which uses callout/hold. Previously the local was queued.
+
+JH/33 Fix a taint trap in the ${listextract } expansion when the source data
+ was tainted.
+
+JH/34 Fix the placement of a multiple-message delivery marker in the delivery
+ log line. The asterisk is now consistently appended to the remote IP
+ (and port, if given), and will also be provided on defer and fail log
+ lines. Previously it could be placed on the local IP if that was being
+ logged, and was only provided on delivery lines.
+
+JH/35 Bug 2343: Harden exim_tidydb against corrupt wait- files.
+
+JH/36 Bug 2687: Fix interpretation of multiple ^ chars in a plaintext
+ authenticator client_send option. Previously the next char, after a pair
+ was collapsed, was taken verbatim (so ^^^foo became ^^foo; ^^^^foo became
+ ^^\x00foo). Fixed to get ^\x00foo and ^^foo respectively to match the
+ documentation. There is still no way to get a leading ^ immediately
+ after a NUL (ie. for the password of a PLAIN method authenticator.
+
+JH/37 Enforce the expected size, for fixed-size records read from hints-DB
+ files. For bad sizes read, delete the record and whine to paniclog.
+
+JH/38 When logging an AUTH failure, as server, do not include sensitive
+ information. Previously, the credentials would be included if given
+ as part of the AUTH command line and an ACL denied authentidcation.
+
+JH/39 Bug 2691: fix $local_part_data. When the matching list element
+ referred to a file, bad data was returned. This likely also affected
+ $domain_part_data.
+
+JH/40 The gsasl authenticator now supports caching of the salted password
+ generated by the client-side implementation. This required the addition
+ of a new variable: $auth4.
+
+JH/41 Fix daemon SIGHUP on FreeBSD. Previously, a named socket for IPC was
+ left undeleted; the attempt to re-create it then failed - resulting in
+ the usual "SIGHUP tp have daemon reload configuration" to not work.
+ This affected any platform not supporting "abstract" Unix-domain
+ sockets (i.e. not Linux).
+
+JH/42 Bug 2693: Harden against a peer which reneges on a 452 "too many
+ recipients" response to RCPT in a later response, with a 250. The
+ previous coding assumed this would not happen, and under PIPELINING
+ would result in both lost and duplicate recipients for a message.
+
+JH/43 Bug 2694: Fix weighted distribution of work to multiple spamd servers.
+ Previously the weighting was incorrectly applied. Similar fix for socks
+ proxies. Found and fixed by Heiko Schlichting.
+
+JH/44 Bug 2701: Fix list-expansion of dns_ipv4_lookup. Previously, it did
+ not handle sub-lists included using the +namedlist syntax. While
+ investigating, the same found for dns_trust_aa, dns_again_means_nonexist,
+ dnssec_require_domains, dnssec_request_domains, srv_fail_domains,
+ mx_fail_domains.
+
+JH/45 Use a (new) separate store pool-pair for DKIM verify working data.
+ Previously the permanent pool was used, so the sore could not be freed.
+ This meant a connection with many messages would use continually-growing
+ memory.
+
+JH/46 Use an exponentially-increasing block size when malloc'ing store. Do it
+ per-pool so as not to waste too much space. Previously a constant size
+ was used which resulted in O(n^2) behaviour; now we get O(n log n) making
+ DOS attacks harder. The cost is wasted memory use in the larger blocks.
+
+JH/47 Use explicit alloc/free for DNS lookup workspace. This permits using the
+ same space repeatedly, and a smaller process footprint.
+
+JH/48 Use a less bogus-looking filename for a temporary used for DH-parameters
+ for GnuTLS. Previously the name started "%s" which, while not a bug,
+ looked as if if might be one.
