./mail/dcc, Anti-spam content filter

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.3.158nb2, Package name: dcc-1.3.158nb2, Maintainer: petar

The Distributed Checksum Clearinghouses or DCC is an anti-spam content filter
that runs on a variety of operating systems. As of the middle of 2007, it
involves millions of users, more than six hundred thousand client computer
systems, and more than 250 servers collecting and counting checksums related to
more than 300 million mail messages on week days. The counts can be used by
SMTP servers and mail user agents to detect and reject or filter spam or
unsolicited bulk mail. DCC servers exchange or "flood" common checksums. The
checksums include values that are constant across common variations in bulk
messages, including "personalizations".

Bump PKGREVISION for perl-5.24.0 for everything mentioning perl.

Log message:
Use PREFIX-relative paths in INSTALLATION_DIRS

While the INSTALLATION_DIRS code actually works fine with directories
that contain PREFIX (by removing it first), the documentation says
that values should be PREFIX-relative.

Pointed out by Petar Bogdanovic ($MAINTAINER).

Log message:
Install two more directories

For an unknown reason, the package build succeeds often with EGDIR not
explicitly created.  However, sometimes it does not.  Because a number
of directories are created by pkgsrc anyway, just add the troublesome
directories to the list.   No PKGREVISION, since this does not affect
any build that previously succeeded.

Log message:
Simplify package, update to 1.3.158.
Update prepared in wip by Petar Bogdanovic.

 * Remove INSTALL and add fix-map to rc-scripts instead (start_precmd).
 * Remove dccm option because it was never properly tested.  If someone
   wants it back, let OWNER know.
 * Remove dcc-spamassassin.pre.  DCC.pm will use cdcc in order to obtain
   homedir and therefore the location of the dccifd socket.
 * Add several minor build/install patches.
 * Remove do-install target since the default (DESTDIR-enabled) install
   now works well enough.


    Do not flood any reports to peers with "leaf=0"
    Fix crash in dccm, dccifd, and dccproc when time jumps backwards by
	more than than 1 millisecond.
    Adjust Makefiles for recent NetBSD.

    Fix `cdcc "help flood"`
    Try `cc -E -w` in ./configure to avoid fatal gcc warning about
	CPPFLAGS=-D_FORTIFY_SOURCE=2 that currently breaks DCC packaging
	on archlinux and will affect other systems.

    Fix editline build problem in cdcc reported by Robert Pelletier.

    Resolve confusion between dccifd ASCII protocol options "no-grey"
	and "grey-off" pointed out by Mark Thomas.

    In `cdcc clients` output, suppress individual client addresses covered
	by an address block in the server /var/dcc/blacklist file except when
	explicitly requested as in `cdcc "clients"`.

    Compress bad client addresses for `cdcc clients`.

    Answer clients with bad client-IDs and passwords as if they were
	using the anonymous client-ID.
    Improve counting by dccd of clients in address blocks.

    Fix missing clients in `cdcc clients`.
    Fix NetBSD threads problem 1.3.146 reported by Petar Bogdanovic.

    Add -I to `cdcc clients`
    Reduce dccifd thread stack size to 512 KBytes for busy 32-bit systems
    Fix some problems in the Windows version of dccproc.

    Suppress some error messages about broken DCC clients from dccd.
    Fix default start and stop Linux run levels in rcDCC as suggested by
	Herve Eychenne.
    Change start-dccifd to use `kill` instead of `/bin/kill` to accommodate
	Linux systems where /bin/kill does not understand `/bin/kill -9 -$PID`
	as the way to kill a process group.
    `cdcc src` now accepts a pair of IPv4,IPv6 addresses.
    Requests from anonymous DCC clients to the public DCC servers are grouped
	by IPv4 /24 or IPv6 /56 address blocks for inflating the delay.

    Fix a rare crash of dccd, the server daemon.
    Allow "." in -B for dccifd, dccm, and dccproc as the base domain
	name of DNSBL to support detecting and rejecting mail containing
	URLs listed in a response policy zone (RPZ).

    Fix `dccifd -V` broken in 1.3.142 reported by Chris Burton.
    Fix "incompatible whitelist" SMTP bug in dccifd introduced in 1.3.139.
    Deal with default -mstructure-size-boundary=8 in FreeBSD on ARM as
	suggested by Ronald Klop.  However, intermittent failures of
	`cdcc "id 1; stats"` on FreeBSD 9.0-STABLE on a system with a
	"Feroceon 88FR131 rev 1 (Marvell core)" seem to be caused by broken
	consistency between write() and mmap().  That suggests that while
	the DCC client software should generally work, the DCC server will
	occassionally fail mysteriously.
    Fix dccm parsing of Received headers for MX and MXDCC whiteclnt lines
	that broke in verseion 1.3.139.

    Improve physical page locality of the DCC server's use of the database
	hash table and so improve server performance.
    The nagios script in var/dcc/libexec/dcc-nagios now compares the clock
	on the DCC server with the local clock.
    `cdcc -VV` and other commands produce the ./configure parameters used to
	build them.
    Build cdcc with editline.
    Add -P to dccproc, dccifd, dccm, and dccsight.

    Fix "MTA-last" in dcc man page as suggested by Bram Grietens.
    Fix no_forced-discard typo reported by Bram Grietens.
    Fix dccm to honor `hackmc -R` and discard relay attacks.
    misc/DCC.pm, which is generated from misc/DCC.pm.in, is now very
	similar to what will probably be in SpamAssassin 3.4.
    Fix problems finding native milter library for dccm pointed out by
	Kevin A. McGrail.
    Improve documentation or help output from the nagios plugin,
    Fix bug in misc/DCC.pm in dealing with mail that already has an
	X-DCC header found and diagnosed by Herbert J. Skuhra.

    tweak some HTML in the whiteclnt proof-of-concept pages
    Fix bug in `wlist` display of address blocks reported by Rob McMahon.
    Fix missing IP address in log files for mail from (as opposed to
	relayed by) MX relays.

    Give temporary rejections by dccm and dccifd for conflicting per-user
	thresholds a separate message.
    Add FreeBSD "faststart" to rcDCC.

    Fix bad URL decoding reported by Kostik.

    Fix some innocuous compilers warnings on Solaris and Ubuntu.

    Fix dccd and cdcc for `cdcc clients` for large operation counts.
    Deal with trailing '.' and other punctuation URLs in dccm, dccifd, and
	dccproc as pointed out by Kostik.  This changes the FUZ1 and FUZ2
	checksums in some cases.
    Fix a free(0).

    /var/dcc/map on 32 and 64 bit versions of a system are now the same.
    Dccproc, dccm, and dccifd decode HTML &#xxx character references in URLs.
    Dccproc, dccm, and dccifd convert UTF-8 domain names to Punycode
	before checking DNS blacklists.
    Deal with Linux `logger` bug that does the wrong thing with something like
	`logger message with -S dash S` as suggested by Leandro Santi.

    Fix compile bug reported by Rob.McMahon involving old compilers
	without "inline"

    Fix DNSBL bugs in parsing http://example.com?parameter and
	http://example.com:80 reported by Kostik
    Increase number of distinct kinds of local or "substitute" headers that
	can be locally white- or blacklisted to 8

    Fix fstatfs() wrapper on Ubuntu and speed up dccd and dbclean when
	a memory file system is used with -H.

    Fix minor bug in updatedcc and fetch-testmsg-whitelist as suggested by
	Taso N. Devetzis.
    Find in_port_t in sys/types.h as reported by Josh Allen.

    Fix serious bug reported by Bart Dumon in DNS whitelists on systems
	without strlcpy().

    Adjust dnswl.org in the sample dcc_conf file.

	homedir/dcc_conf file.
    Fix dccproc, dccifd, and dccm crash in parsing Received: fields with
	IPv6 addresses.
    Parse IPv6 address literals lacking the "IPv6:" tag in Received: \ 

    Fix problem with `dbclean -H` after a system reboot reported by Gary Mills.
    Fix "duplicate symbol" problem on MacOS X or Darwin 10.3.0
	reported by Robert Pelletier by removing the use of `ranlib -c`.
