Exim version 4.98 ----------------- +JH/01 Use fewer forks & execs for sending many messages to a single host. + By passing back more info from the transport to the delivery process, + we can loop there. A two-phase queue run will benefit, particularly for + mailinglist and smarthost cases. + +JH/02 Add transaction support for hintsdbs. The providers supported are tdb and + sqlite. Transactions are used for the wait-transport and retry DBs. + They imply locking internal to the DB. We no longer need a separate + lockfile, can keep the DB handle open for extended periods, yet + potentially benefit from concurrency on non-conflicting record uses. + +JH/03 With dkim_verify_minimal, avoid calling the DKIM ACL after the first + good verify. + +JH/04 Remove the docs and support scripts dealing with conversion of Exim + version 3 installations. + +JH/05 Fix hintsdb support for dbmjz when compiled using sqlite3. Previously + the backend support assumed keys would be simple C strings, but dbmjz + uses keys with embedded NUL bytes. The builtin hintsdb use is unaffected, + but installations using dbmjz will need to rebuild those DBs. + +JH/06 Bug 1141: When operating a continued-connection transport, verify that + the interface option, if specified, evaluates to match the connection. + Previously, a queued message for the same host was sent without checking. + +JH/07 Bug 3106: Fix coding in SPA authenticator. A macro argument was not + properly parenthesized, resulting in a logic error. While the simple + fix was provided by Andrew Aitchison, the over-large code block resulting + from this macro made me want to replace it with a real function so more + extensive rework becamse needed. + +JH/08 The output of "exim -bV" now includes lookup types built as dynamic-load + modules. + +JH/09 Not a change, but worthy of note: There is no test coverage of the + heimdall-gssapi authenticator driver. It does build, though with (on at + least one platform) library version conflicts with the gsasl auth + driver). Confidence in its operation is lacking. + +JH/10 Bug 3108: On platforms not providing strchrnul() [OpenBSD] supply a proper + prototype (as well as implementaton). Previously, a return type "int" + was assumed, resulting in type-conversion bugs when int and pointer had + different size. This resulted in crashes while processing DKIM signatures + of received messages. Identification and fix from Qualys Security. + +JH/11 Lookups built as dynamic-load modules which support a single lookup + type are now only loaded if required by the config. Previously all lookup + modules present in the modules directory were loaded; this now applies + only to those supporting multiple types. + +JH/12 Bug 3112: Fix logging of config-file position for "obsolete lookup + syntax". Previously, the end of the top-level file was reported. + +JH/13 Bug 3120: Fix parsing of DKIM pubkey DNS record. Previously a crafted + record could crash the meesage recieve process. Investigation by + Maxim Galaganov. + +Exim version 4.98 +----------------- + JH/01 Support list of dkim results in the dkim_status ACL condition, making it more usable in the data ACL. @@ -128,6 +189,47 @@ JH/24 Bug 3081: Fix a delivery process crash. When the router "errors_to" JH/25 Bug 3079: Fix crash in dbmnz. When a key was present for zero-length data a null pointer was followed. Find and testcase by Sebastian Bugge. +JH/26 Fix encoding for an AUTH parameter on a MAIL FROM command. Previously + decimal 127 chars were not encoded, and lowercase hex was used for + encoded values. Outstanding since at least 1999. + +JH/27 Fix crash in logging. When a message with a large number of recipients + had been received, and logging of recipients is enabled, the buffer used + for logging could reach limit. A read using a null pointer would then + be done, resulting in a crash of the receiving process before an SMTP + ACK for the message was returned to the sending system. Duplicate + messages were created as a result. + Find and debug help by Mateusz Krawczyk + +JH/28 Bug 3086: Fix exinext for ipv6. Change the format of keys in the retry + DB, wrapping transport record bare-ip "host names" and ipv6 + "host addresses" in square-brackets. This makes the parsing that + exinext does more reliable. + +JH/29 Bug 3087: Fix SRS encode. A zero-length quoted element in the local-part + would cause a crash. + +JH/30 Bug 3029: Avoid feeding Resent-From: to DMARC. + +JH/31 Bug 3027: For -bh / -bhc tests change to using the compressed form of + ipv6 addresses for the sender. Previously the uncompressed form was used, + and if used in textual form this would result in behavior difference + versus non-bh. + +JH/32 Bug 3096: MAIL before HELO/EHLO, where required by hosts_require_helo, is + now classed as a protocol error and subject to smtp_max_synprot_errors. + +JH/33 Bug 2994: A subdir dsearch lookup should permit a directory name that starts + ".." and has following characters. + +JH/34 Fix delivery ordering for 2-phase queue run combined with + queue_run_in_order. + +JH/35 Bug 3099: fix parsing of MIME filename= split over multiple paramemters. + Previously the $mime_filename variable would have an incorrect value. + While in the code, extend coverage to name= which previously was only + supported for single parameters, despite also filling in $mime_filename. + Exim version 4.97 -----------------
