Please update package for Ubuntu 9.04

Changelog for vsftpd 2.1.0
===================

- Remove .postlogin.c.swp (thanks Kaibin Li <email address hidden>)!
- findlibs repairs for libcap; builds on my Ubuntu 6.06 again.
- Apply patch to fix "error: assignment of read-only member '__in'" build
error on broken systems where the WIFEXITED() etc. macros write to their
argument. Thanks Ingo Terpelle <email address hidden>.
- Replace spaces in xferlog with underscores, report from
Michael Wittauer <email address hidden>.
- Reload default config values before re-parsing config file on SIGHUP. This
makes the values correct in the case a setting was removed from the file.
- Do not issue an FTP response for a blank line on the control channel. Fixes
issues with some broken NAT devices. ProFTPd does the same, so hopefully
nothing will break. Report from Frank Bulk <email address hidden>.
- Replace usage of broken _syscall() with syscall(). Fixes build errors for
those without libcap-devel installed.
- Add implicit SSL support with implicit_ssl option.
- Remove arbitrary restriction on one process model + SSL.
- Set a session ID on the SSL context.
- Add the skeleton of a built-in ptrace sandbox. Not yet useful for anything
other than catching compile errors. Yes, I'm crazy :P
- Use PR_SET_PDEATHSIG all over the place so that when the listener is killed,
existing sessions are booted too.
- Use SSL_peek; makes SSL pipelining work. Note that I never found any SSL
client that need it, but still a nice code clean-up.
- Change ASCII download behaviour so \r\n does not become \r\r\n. This mirrors
proftpd behaviour instead of wu-ftpd. Thanks Paul Abel <email address hidden>.
- Switch all sighandlers to the synchronous ones. Prevents us having to
block and unblock signals all the time.
- Add a "use alarm" option to synchronous signal handlers, to ensure the race
condition against a blocking call does not result in a permanent
non-delivery.
- Use SIGTERM for privileged parent process shutdown, so they can still update
u/wtmp properly.
- Do RAND_load_file from /dev/urandom in the child context because I don't
trust the OpenSSL API vs. fork(). Different children do have different RNG
state; this is defense in depth.
- More thoroughly close the remote ends of the priv_sock, ensuring that child
death results in no blocking in the parent. This is a matter of tidyness; the
SIGCHLD handler will reliably tear down the parent.
- Do the same for the SSL slave / consumer channels.
- Fix OpenBSD build.
- Move SSL data handling into the SSL slave process. Incurs some extra
overhead in terms of context switches and copies, but it enables this next
item:
- By default, require SSL data connections to exhibit SSL session re-use of
the control channel. Unlike the cert thing, this _is_ something we can turn
on by default as most clients seem to do reuse. Yay.
- Change 522 response for SSL connection fail to note when session reuse is
required.
(v2.1.0pre1 here)
- More work on the inbuilt ptrace()-sandbox support.
- Clear the idle alarm when starting data transfer if there is no data alarm.
- Fix syslog format; don't embed 2nd copy of date, pid. Thanks to
Renй Berber <email address hidden>.
- Lock file before truncating it for upload. Fixes various simultaneous
upload corruption issues.
- Make sure to give 426 error code on uploads if ABOR was received.
- Add cmds_denied option to complement cmds_allowed.
- Ignore lines in config file containing only white space.
- Require write_enable / anon_upload_enable / etc. to process STOU.
- FC10 patch (vsftpd-1.0.1-missingok.patch): tweak to logrotate file.
- FC10 patch (vsftpd-1.2.1-nonrootconf.patch): bail if the config file is not
owned by the currently running user.
- FC10 patch (vsftpd-2.0.1-tcp_wrappers.patch): explicitly call openlog() to
avoid syslog() bug where some settings are not initialized.
- FC10 patch (vsftpd-2.0.3-daemonize_fds.patch): when backgrounding, replace
fd 0,1,2 with /dev/null fd.
- FC10 patch (vsftpd-2.0.5-correct_comments.patch): comment tweaks in the
sample config file.
- FC10 patch (vsftpd-2.0.5-fix_unique.patch): use the default filename given
by STOU if it is available.
- FC10 patch (vsftpd-2.0.5-pam_end.patch): call pam_end() properly so modules
can act on errors if they want.
- FC10 patch (vsftpd-2.0.5-pasv_dot.patch): Strict RFC compliance for PASV
command; add a trailing period.
- FC10 patch (vsftpd-2.0.5-uname_size.patch): allow longer usernames. It's not
1990 any more, so trust PAM etc. to not stack-buffer-overflow.
- FC10 patch (vsftpd-2.0.5-underscore_uname.patch): permit username to start
with underscore or period.
- FC10 patch (vsftpd-2.0.6-listen.patch): default listen to YES.
- Fix crash on SIGHUP introduced in 2.1.0pre1. Oops.
- FC10 patch (vsftpd-2.0.5-bind_denied.patch): retry PASV bind() on EACCES
too, which can happen on SELinux systems.
- Default resource limit for child processes: 100MB address space.
- Finishing touches to the initial sandbox policy; only permit connect() to
the host on the control channel being the nicest touch.
(v2.1.0pre2 here)
- Fix 64-bit build (oops)! Thanks Martin Nagy <email address hidden>.
- Fix config of SSL built in; not enabled; two process model. Report from
Martin.
- Shutdown the command connection in the priv parent's SIGTERM handler; kills
of children where the PR_SET_PDEATHSIG cannot due to different user ids.
(v2.1.0pre3 here)
- Fix build on FC10.
- Some FAQ tweaks.
- Permit fcntl(F_GETFD) in sandbox policy. Needed for FC10. Not sure where it
comes from but it is harmless. (My guess would be glibc-2.9's new support for
using O_CLOEXEC more).
- Fix build warning on 64-bit.
- Fix build on OpenBSD again.
(v2.1.0pre4 here)
- Bring userlist_deny handling inside the max_login_fail accounting.
