From bbe902f07b0bd4a78901962c9f679e2ef2d013c5 Mon Sep 17 00:00:00 2001 From: Philip Hazel Date: Fri, 14 Jan 2005 11:06:58 +0000 Subject: [PATCH] Incorporated the 4.44 ChangeLog into the main ChangeLog so that a historical record is preserved. It is separate from the 4.50 entries, many of which are duplicates, and there's an explanation about why. --- doc/doc-txt/ChangeLog | 160 +++++++++++++++++++++++++++++++++++++++++- 1 file changed, 159 insertions(+), 1 deletion(-) diff --git a/doc/doc-txt/ChangeLog b/doc/doc-txt/ChangeLog index 6c6b6641c..a5ae2700e 100644 --- a/doc/doc-txt/ChangeLog +++ b/doc/doc-txt/ChangeLog @@ -1,8 +1,26 @@ -$Cambridge: exim/doc/doc-txt/ChangeLog,v 1.71 2005/01/14 10:25:33 ph10 Exp $ +$Cambridge: exim/doc/doc-txt/ChangeLog,v 1.72 2005/01/14 11:06:58 ph10 Exp $ Change log file for Exim from version 4.21 ------------------------------------------- + +A note about Exim versions 4.44 and 4.50 +---------------------------------------- + +Exim 4.50 was meant to be the next release after 4.43. It contains a lot of +changes of various kinds. As a consequence, a big documentation update was +needed. This delayed the release for rather longer than seemed good, especially +in the light of a couple of (minor) security issues. Therefore, the changes +that fixed bugs were backported into 4.43, to create a 4.44 maintenance +release. So 4.44 and 4.50 are in effect two different branches that both start +from 4.43. + +I have left the 4.50 change log unchanged; it contains all the changes since +4.43. The change log for 4.44 is below; many of its items are identical to +those for 4.50. This seems to be the most sensible way to preserve the +historical information. + + Exim version 4.50 ----------------- @@ -323,6 +341,146 @@ Exim version 4.50 check. A QUIT command is no longer sent after a timeout. +---------------------------------------------------- +See the note above about the 4.44 and 4.50 releases. +---------------------------------------------------- + + +Exim version 4.44 +----------------- + + 1. Change 4.43/35 introduced a bug that caused file counts to be + incorrectly computed when quota_filecount was set in an appendfile + transport + + 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The + bug fixed in 4.43/37 would have been diagnosed quickly if this had been in + place. + + 3. Give more explanation in the error message when the command for a transport + filter fails to execute. + + 4. There are several places where Exim runs a non-Exim command in a + subprocess. The SIGUSR1 signal should be disabled for these processes. This + was being done only for the command run by the queryprogram router. It is + now done for all such subprocesses. The other cases are: ${run, transport + filters, and the commands run by the lmtp and pipe transports. + + 5. Some older OS have a limit of 256 on the maximum number of file + descriptors. Exim was using setrlimit() to set 1000 as a large value + unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these + systems. I've change it so that if it can't get 1000, it tries for 256. + + 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This + was an oversight, and furthermore, ever since the addition of extra + controls (e.g. 4.43/32), the checks on when to allow different forms of + "control" were broken. There should now be diagnostics for all cases when a + control that does not make sense is encountered. + + 7. $recipients is now available in the predata ACL (oversight). + + 8. Tidy the search cache before the fork to do a delivery from a message + received from the command line. Otherwise the child will trigger a lookup + failure and thereby defer the delivery if it tries to use (for example) a + cached ldap connection that the parent has called unbind on. + + 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value + of $address_data from the recipient verification was clobbered by the + sender verification. + +10. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0 + was its contents. (It was OK if the option was not defined at all.) + +11. A "Completed" log line is now written for messages that are removed from + the spool by the -Mrm option. + +12. $host_address is now set to the target address during the checking of + ignore_target_hosts. + +13. When checking ignore_target_hosts for an ipliteral router, no host name was + being passed; this would have caused $sender_host_name to have been used if + matching the list had actually called for a host name (not very likely, + since this list is usually IP addresses). A host name is now passed as + "[x.x.x.x]". + +14. Changed the calls that set up the SIGCHLD handler in the daemon to use the + code that specifies a non-restarting handler (typically sigaction() in + modern systems) in an attempt to fix a rare and obscure crash bug. + +15. Narrowed the window for a race in the daemon that could cause it to ignore + SIGCHLD signals. This is not a major problem, because they are used only to + wake it up if nothing else does. + +16. A malformed maildirsize file could cause Exim to calculate negative values + for the mailbox size or file count. Odd effects could occur as a result. + The maildirsize information is now recalculated if the size or filecount + end up negative. + +17. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this + support for a long time. Removed HAVE_SYS_VFS_H. + +18. Updated exipick to current release + +19. Allow an empty sender to be matched against a lookup in an address list. + Previously the only cases considered were a regular expression, or an + empty pattern. + +20. Exim went into a mad DNS lookup loop when doing a callout where the + host was specified on the transport, if the DNS lookup yielded more than + one IP address. + +21. Respect the 75-character limit for "encoded words" when doing RFC 2047 + encoding, and increase the buffer size for ${rfc2047: expansion. + +22. errors_to on a router was being ignored for bounce messages. + +23. If an IPv6 address is given for -bh or -bhc, it is now converted to the + canonical form (fully expanded) before being placed in + $sender_host_address. + +24. Updated eximstats to version 1.33 + +25. Expand error message when GnuTLS has problems setting up cert/key files. + +26. Expand error message when OpenSSL has problems setting up cert/key files. + +27. Reset locale after calling embedded Perl, in case it was changed. + +28. When checking for a message's continued existence, exim_tidydb was not + looking in the split spool subdirectories. + +29. eximstats updated to version 1.35 + 1.34 - allow eximstats to parse syslog lines as well as mainlog lines + 1.35 - bugfix such that pie charts by volume are generated correctly + +30. A forced expansion failure in the SPA authenticator is now treated the + same as in other authenticators (it moves to the next authenticator). + +31. Fixed the cipher preference order for GnuTLS client usage. + +31. Fixed Sieve buglet: now it explicitly sets From: when generating + an autoreply. + +32. More robust handling of very large SMTP responses. + +33. Check dnsdb PTR key for IP address before reversing. + CAN-2005-0021 + +34. Put a check in host_aton() to protect against buffer overrun + CAN-2005-0021 + +35. Fix buffer overflow vulnerability in spa_base64_to_bits() function. + CAN-2005-0022 + +36. Need to initialize getloadavg() as root in the daemon when + deliver_drop_privilege is set, for the benefit of the queue runner. + +37. Data saved for $host_data after a lookup involving a named host list was + corrupted if there was more than one message in an SMTP session. + +38. Fixed a very old bug that sometimes lost the final 221 message after QUIT. + + Exim version 4.43 ----------------- -- 2.30.2
