(updated 2008-01-10) There are a FAQ document and documentation on the hostname issue as
well as the README.
Leafnode 1.11 is an IPv6-enabled drop-in replacement for
leafnode 1.10 and leafnode 1.9.
leafnode 1.11 is a stable release, that means that it will not
change except for bugfixes or documentation.
Additionally, leafnode-1 is in maintenance mode, that means, no
features will be added (these all go into the 2.0 tree), only bug fixes will be made as bugs are
1.11.11 (released 2015-08-24)
- The configfile parser now strips whitespace between a configuration
parameter's value and a trailing comment. Found by Cecil Westerhof.
- The roff manual page sources now render proper hyphens (-), minus characters
(\-) and en-dashes (\[en]) depending on their context. This is so that
copying-and-pasting from the manual page works properly.
- The code that checks if the peer is local now properly deals with IPv4
mapped IPv6 addresses.
1.11.10 (released 2013-06-11)
- Some more format strings that used the 'h' width specifier have been
changed to remove it, and cast the argument instead, in case we must use
our snprintf.c replacement.
Fixes FreeBSD PR#179483 and https://sourceforge.net/p/leafnode/bugs/19/,
debugged and reported by Alexey Markov.
- The configure.ac updates broke detection of a working snprintf, so that
the bug above was exposed on many systems.
- When cross-compiling, leafnode now assumes that the target has a proper
snprintf implementation, and will not provide its own.
1.11.9 (released 2013-06-10)
- The whoami() function is now IPv6 enabled. Code contributed to openSUSE by
Boris Manojlovic and submitted by Andreas Stieger, with additional bugfixes
by Robert Grimm, fixing Debian Bug #667998, reported by Jose Antonio Ortega
- Do not delete news spool on "make uninstall" (which would lose all data),
but instead only print instructions how the user could do that.
Reported by Pasi Kallinen, fixes SourceForge bug #3520120.
- The --with-user= now propagates to leafnode.xinetd.
Inspired by a bug report sent by Ken Robinson.
- When complaining that we are unable to switch the user ID, report the
current real and effective user IDs to ease debugging.
Inspired by a bug report sent by Ken Robinson.
- Leafnode no longer supports PCRE versions before 2.06.
- Leafnode now lets autoconf look for a good sed command, and runs it
instead of a hard-coded "sed" (first from the $PATH) from "subst".
- Leafnode's subst program (run during build) now runs sed under LC_ALL=C.
This might fix SourceForge Bug#3575233 reported by Martin Krischik,
where leafnode failed to compile under macports for MacOS X 10.8.
- Work around compilation failures in ma_sock2name.c due to broken
IN6_IS_ADDR_V4MAPPED macro on Linux eglibc (Ubuntu 12.04) when
compiling in strict conformance mode.
- configure.ac updates to avoid autoconf warnings on newer autoconf versions.
- Remove some compiler warnings that were enabled during development, but
are not terribly useful on code that is not going to change much.
Previous releases, discontinued and unsupported
1.11.8 (released 2010-06-12)
- Performance optimization, reported by Gary R. Schmidt.
- Fix a compiler warning on computers where "long" is a wider type than "int",
such as many 64-bit computers.
- Fix compiler warnings on computers where "long" is a wider type than
"time_t", such as NetBSD 5.X on 64-bit computers.
- Fix compiler warning "dereferencing type-punned pointer will break
- Fix a file descriptor leak in fetchnews.c's getbody_newno function; reported
to Debian BTS by Helmut Grohne, fix by Robert Grimm.
- Leafnode now enables IPv6 support by default. Use --without-ipv6 to disable.
- Leafnode now supports detecting if a peer is in a local network also
for IPv6 global addresses, providing that the host OS provides getifaddrs().
This comprises Linux, NetBSD, FreeBSD, but not, for instance, Solaris 10.
Reported missing by M. G. Berberich.
- Leafnode is now always compiled in maintainer mode.
This has no impact on run-time behaviour.
- Leafnode now assumes that handlers for signal() do not return a value.
- Skip arbitrary amounts of contiguous CR right before LF. Reported by John R.
- Remove the long-obsoleted README.FIRST file.
- The FAQ has information on how to copy the spool.
- FAQ: The MAC OS X two-level namespace documentation for PCRE was removed,
PCRE is no longer part of the leafnode distribution.
- FAQ: mention how to fix losing unsubscriptions of low-traffic groups in slrn
- config.example: The expire documentation should now be clearer and closer to
the one in the leafnode(8) manual page. Along the lines discussed by Chris G
and Whiskers on the leafnode mailing list.
1.11.7 (released 2009-04-20)
- fetchnews: If the LN_SUPPRESS_DATE environment variable is defined and set
to any value or empty, fetchnews will not test the upstream server's time by
means of the "DATE" NNTP command.
This can be used to quench related log messages.
- Fix logging if texpire unlinks files without further hardlinks from
- Fix potential segfault on libcs that do not catch NULL for %s formatting
(several GNU libc versions do) when trying to retrieve delayed bodies from
corrupt article headers. Pretend success, to purge article number from
subscription file. Bug reported by Chris Carr.
- Fix & change "noactive" so that it can be overridden by "fetchnews -f", as
documented in config.example.
Regression as side effect of 1.9.50 fix, reported by Jesse F. Hughes.
- Fix logged IP address in "connected to..., reply:" message when compiled
without IPv6 support.
Fixes Mandriva Bug #45605, reported by David W. Hodgins.
- Print connected to... to console as well at proper verbosity level, found
by maintainer while debugging aforementioned bug.
- Only emit warning that no server with posting permission was found if that's
actually needed. Reported by Christian Weiske.
- If corrupted articles had been detected, fetchnews -x NNN would not be able
to re-fetch the said article because a 0-sized file remained in message.id,
making fetchnews believe the article was in the spool.
0-sized message.id/NNN/ files are now purged when checking if the article is
already in the spool.
Reported by Peter Bauernfeind. (de.comm.software.newsserver post, May 2008)
- Change interface enumeration to track incompatible NetBSD 5 changes. The
latter led to bogus connection refusals in NNTPD. SourceForge Bug #2700756,
by Aleksey Cheusov, fix suggested by Roy Marples.
- Add support for SIOCGIFALIAS where available (BSD) in order to obtain
netmasks for 4.4BSD-style IP aliases.
getifaddrs() has been suggested as well, but it isn't available everywhere,
so we would have to keep the old code around anyways, and we can just fix
that rather than introduce alternative code branches.
BUGFIXES BACKPORTED FROM LEAFNODE 2
- lsort (used by make update) now detects and report errors.
- "make update" handles the lockfile properly now: it records its PID and
removes the lock also in cases of failure.
- "make update" restores the old groupinfo file if lsort fails.
- "make update" now builds an up-to-date lsort first.
- "make update" now uses the configured NEWS_USER and _GROUP.
- "make update" is now a phony Makefile target, i. e. it will work even
if there is a file "update" in the build directory.
- When creating a Path: header (because the newsreader did not do that), use
"not-for-mail" instead of NEWS_USER (usually "news") as the user component.
This seems to resolve propagation issues with 2nd-hop-upstreams, as reported
in Debian Bug#459980 by Michael Weitzel, with Universität Siegen, Germany.
- When writing to client fails, log decoded errno, too.
This can help debugging certain firewall misconfigurations more easily.
- Undoing a wordwrap in configure.ac allows for bootstrapping on Cygwin.
- Drop obsolete mysetvbuf().
- leafnode-version now supports an additional "-v" mode to print more
information on the installation. The output then is similar, but not
identical - due to different feature sets - to the way leafnode-2 prints it.
- Add some comments to UNINSTALL-daemontools
- Put README-FQDN* under leafnode's license. Found to be in conflict with
Debian's DFSG by Mark Brown.
1.11.6 (released 2007-03-17)
- .site TLDs are refused in FQDN.
- apply patch from Georg Schwarz to fix compilation with SGI IDO cc.
- do not delete articles if the References: lines are malformatted.
Reported by Adam Funk.
- support autoconf 2.60, fixing datarootdir-related warnings.
- fix minor typos in README-FQDN.
- minor changes to INSTALL.
1.11.5 (released 2006-04-09)
- Fix logging of invalid FQDH/FQDN.
- Do not trash delaybody download markers if the interesting.group/* files
are writeable by NEWS_USER ("news") but owned by somebody else. Found
debugging a problem described by David Aldred.
- Some syslog messages were still logged at LOG_DEBUG priority without
- Support noactive = 0. Reported by Rafal Maj, Debian Bug #329760.
- Support nodesc = 0.
- Keep non-expiring groups (negative groupexpire date) in active file even if
they have expired upstream. Sourceforge Bug #1230256, Thomas Zajic.
- INSTALL: leafnode needs a "news" group as well. Found by Julien Sansonnens.
- Allow unterminated lines in regular files. Found by Ivo Maintz.
- Applyfilter unfolds headers before matching, to match fetchnews behavior.
- Applyfilter no longer unconditionally removes messages without body
if delaybody is off. The interesting.groups/group.name file might still
have pointers so that fetchnews will download the bodies later.
- "killed nnn (<email@example.com>), already fetched before" messages have been
demoted to debug priority, to avoid syslog spamming with multiple upstream
servers or after crashes. Reported by Adam Funk.
- The RPM is now accompanied by a -debuginfo package.
- Build "grouplist" program in "make check".
- The fetchnews manual pages states that -f is not to be used in cron jobs.
- The filtering documentation (applyfilter(8) man page and filters.example)
was overhauled, at the suggestion of Michael R. McCarrey.
Mike also courteously provided additional filter examples with documentation.
- http://www.leafnode.org/ is now served by SourceForge's VHOST service and
thus serves the same content as http://leafnode.sourceforge.net/
1.11.4 (released 2005-11-23)
- Skip server processing when posting articles fails, for instance,
because of a protocol error or server disconnect/timeout.
Bug found when analyzing Debian #318644.
- Do not mark the active for refetch when the failed server has "noread" set
or fetchnews is in -P (post only) mode. Patch by Brian Sammon.
- GNU coreutils 5.92 are broken and can no longer create a missing directory
with "mkdir -p missing/." Work around the bug. Reported by Michael Shigorin.
- Switch FAQ.pdf formatting back to XSL stylesheets and RenderX XEP 4.4,
now that a personal license for OpenSource documentation is available.
- Renamed all CAN-YYYY-NNNN to CVE-YYYY-NNNN in leafnode-SA-*.txt, ChangeLog,
NEWS and OLDNEWS to chase the CVE database change of 2005-10-19.
1.11.3 (released 2005-06-08)
- Fetchnews did not detect timeouts while it was downloading an article
header, which malicious upstream servers could exploit to mount a denial of
service attack against the fetchnews client. See leafnode-SA-2005-02.txt.
CVE Name: CVE-2005-1911
- Bugfix sed expression in makesubst script. (Reported by Jeff Zacharias.)
- texpire now tags the message.id expired count with "message.id" rather than
"total:" to avoid misleading the user who assumes that "total:" would have
to be the sum of the group counts. See also the FAQ change below.
SourceForge bug #1215453.
- When debugmode and verbose mode are set, leafnode programs now print a
warning to stdout that the user should check syslog.conf and the syslog
output rather than the screen print for debugging and sleeps for three
- Add FAQ entry to explain discrepancies between texpire group counts and
message.id expired articles counts.
- Add FAQ entry to explain influence of Gnus' gnus-read-active-file setting
on lost subscriptions, and extend stop fetchnews from unsubscribing FAQ.
Debian bug #307685.
- Drop FAQ entry on license issues as some parts of leafnode are in fact GPLd.
- Drop FAQ entry on why old articles aren't posted, obsolete since 1.9.33.
- INSTALL and INSTALL_de have been polished.
- Add a hint that syslog.conf must be edited to config.example.
- leafnode(8) mentions that LIST ACTIVE keeps an existing subscription fresh.
1.11.2 (released 2005-05-04)
For these two bugs together, the CVE Name is CVE-2005-1453.
For further cross-references, see
- Fix fetchnews segfault when connection to server dies while fetchnews is
reading an article body (use-after-free bug). Regression introduced into
leafnode v1.9.52. Denial of service possible, see leafnode-SA-2005-01.txt.
- Fix fetchnews segfault when connection to server dies while fetchnews is
reading an article header. Regression in security fix of leafnode v1.9.48.
Denial of service possible, see leafnode-SA-2005-01.txt
- fetchnews will no longer re-fetch the active file for a server if it has been
completely received even if fetching articles from this server encounters a
problem. Long-standing bug. Debian bug #70052.
- fetchnews will now properly mark the active for complete re-fetch if it says
so. Previously, it forgot the mark in some circumstances.
- A problem fetching the active file or descriptions for a newly added server
will now mark the active for re-fetch even if articles have successfully
been retrieved from the same server.
- Repair two lines in the German leafnode(8) manual page that became invisible
as they ran together with a .PP macro.
1.11.1 (released 2005-04-25)
- Fix pluralization bug in "n article[s] posted" message, Debian bug #303157.
- Fix other pluralization bugs.
- Update address of web site in pseudo article, reported by Daniel Zwick.
- Backport leafnode-2 code to prefer /usr/xpg4/bin/id (if present) to
/usr/bin/id, to improve portability to Solaris and avoid bogus warnings
- Remove TODO file.
- Update documentation and addresses of mailing lists and web sites,
there have been obsolete links around in code, pseudo article and
- Add missing IPv6 hints to README files.
- Add incompatibility hint WRT configuration parser to README files.
- Clarify differences between global and server-specific parameters
in leafnode(8) manual pages.
1.11.0 (released 2005-03-16)
- fetchnews now supports IPv6 (this causes the version bump to 1.11)
- the configuration parser now supports quoted strings on the right-hand
side, so that "#" can be used in passwords. See the section
CONFIGURATION in leafnode(8) for details.
- Fix snprintf test that caused leafnode to always use the local
snprintf rather than the system's. Bug found by Bruno Rohee.
Regression in leafnode-1.10.7, though with no user-visible effect.
For the history between 1.9.20 and 1.10.8, please see the OLDNEWS.html file.
The files offered below contain a PCRE package to ease
installation, but it is recommended to get the current PCRE
package from http://www.pcre.org/ and build and
install that prior to building leafnode.
