vsftpd: update to 3.0.5

Changelog:

Since 3.0.3:
- Fix build on Fedora 33 (one warning, one incorrect libcap used).
- Fix SSL build (terrible grep for symbol in vsf_findlibs.sh)!
- Fix runtime SIGSYS crashes on Fedora 33 (seccomp sandbox policy tweaks).
- Reject HTTP verbs pre-login.
- Disable TLS prior to v1.2 by default.
- Close the control connection after 10 unknown commands pre-login.
- Reject any TLS ALPN advertisement that's not 'ftp'.
- Add ssl_sni_hostname option to require a match on incoming SNI hostname.

Since 3.0.4:
- Fix ALPN callback to correctly select the 'ftp' string if present. Works
with FileZilla-3.55.0.
- Fix a couple of seccomp policy issues with Fedora 34.

And while here, also add a SunOS SMF manifest.

vsftpd: updated to 3.0.3

v2.3.5
======
- Try and force glibc to cache zoneinfo files in an attempt to work around
glibc parsing vulnerability. Thanks to Kingcope.
- Only report CHMOD in SITE HELP if it's enabled. Thanks to Martin Schwenke
<martin@meltin.net>.
- Some simple fixes and cleanups from Thorsten Brehm <tbrehm@dspace.de>.
- Only advertise "AUTH SSL" if one of SSLv2, SSLv3 is enabled. Thanks to
steve willing <eiji-gravion@hotmail.com>.
- Handle connect() failures properly. Thanks to Takayuki Nagata
<tnagata@redhat.com>.
- Add stronger checks for the configuration error of running with a writeable
root directory inside a chroot(). This may bite people who carelessly turned
on chroot_local_user but such is life.

v3.0.0
======
- Update vsf_findlibs.sh to work on Ubuntu 11.10+
- Make listen mode the default.
- Add -Werror to build flags.
- Fix missing "const" in ssl.c
- Add seccompsandbox.c to support a seccomp filter sandbox; works against Ubuntu
12.04 ABI.
- Rearrange ftppolicy.c a bit so the syscall list is easily comparable with
seccompsandbox.c
- Rename deprecated "sandbox" to "ptrace_sandbox".
- Add a few more state checks to the privileged helper processes.
- Add tunable "seccomp_sandbox", default on.
- Use hardened build flags. Distros of course override these and provide their
own build flags but no harm in showing how it could be done.
- Retry creating a PASV socket upon port reuse race between bind() and listen(),
patch from Ralph Wuerthner <ralph.wuerthner@de.ibm.com>.
- Don't die() if recv() indicates a closed remote connection. Problem report
on a Windows client from Herbert van den Bergh,
<herbert.van.den.bergh@oracle.com>.
- Add new config setting "allow_writeable_chroot" to help people in a bit of
a spot with the v2.3.5 defensive change. Only applies to non-anonymous.
- Remove a couple of fixed things from BUGS.
- strlen() trunction fix -- no particular impact.
- Apply some tidyups from mmoufid@yorku.ca.
(vsftpd-3.0.0-pre1)
- Fix delete_failed_uploads if there is a timeout. Report from Alejandro
Hernández Hdez <aalejandrohdez@gmail.com>.
- Fix other data channel bugs such as failure to log failure upon timeout.
- Use exit codes a bit more consistently.
- Fix bad interaction between SSL and trans_chunk_size.
- Redo data timeout to fire properly for SSL sessions.
- Redo idle timeout to fire properly for SSL sessions.
- Make sure PROT_EXEC isn't allowed, thanks to Will Drewry for noticing.
- Use 10 minutes as a max linger time just in case an alarm gets lost.
(vsftpd-3.0.0-pre2)
- Change PR_SET_NO_NEW_PRIVS define, from Kees Cook.
- Add AES128-SHA to default SSL cipher suites for FileZilla compatibility.
Unfortunately the default vsftpd SSL confiuration still doesn't fully work
with FileZilla, because FileZilla has a data connection security problem:
no client certificate presentation and no session reuse. At least the error
message is now very clear.
- Add restart_syscall to seccomp policy. Triggers reliably if you strace whilst
a data transfer is in progress.
- Fix delete_failed_uploads for anonymous sessions.
- Don't listen for urgent data if the control connection is SSL, due to possible
protocol synchronization issues.

v3.0.1
======
- Fix some seccomp related build errors on certain CentOS and Debian versions.
- Seccomp filter sandbox: missing munmap() -- oops. Did you know that qsort()
opens and maps /proc/meminfo but only for larger item counts?
- Seccomp filter sandbox: deny socket() gracefully for text_userdb_names.
- Fix various NULL crashes with nonsensical config settings. Noted by Tianyin Xu
<tixu@cs.ucsd.edu>.
- Force cast to unsigned char in is* char functions.
- Fix harmless integer issues in strlist.c.
- Started on a (possibly ill-advised?) crusade to compile cleanly with
Wconversion. Decided to suspend the effort half-way through.

v3.0.2
======
- One more seccomp policy fix: mremap (denied).
- Support STOU with no filename, uses a STOU. prefix.

v3.0.3
======
- Increase VSFTP_AS_LIMIT to 200MB; various reports.
- Make the PWD response more RFC compliant; report from Barry Kelly
<barry@modeltwozero.com>.
- Remove the trailing period from EPSV response to work around BT Internet
issues; report from Tim Bishop <tdb@mirrorservice.org>.
- Fix syslog_enable issues vs. seccomp filtering. Report from Michal Vyskocil
<mvyskocil@suse.cz>. At least, syslogging seems to work on my Fedora now.
- Allow gettimeofday() in the seccomp sandbox. I can't repro failures, but I
probably have a different distro / libc / etc. and there are multiple reports.
- Some kernels support PR_SET_NO_NEW_PRIVS but not PR_SET_SECCOMP, so handle
this case gracefully. Report from Vasily Averin <vvs@odin.com>.
- List the TLS1.2 cipher AES128-GCM-SHA256 as first preference by default.
- Make some compile-time SSL defaults (such as correct client shutdown
handling) stricter.
- Disable Nagle algorithm during SSL data connection shutdown, to avoid 200ms
delays. From Tim Kosse <tim.kosse@filezilla-project.org>.
- Kill the FTP session if we see HTTP protocol commands, to avoid
cross-protocol attacks. A report from Jann Horn <jann@thejh.net>.
- Kill the FTP session if we see session re-use failure. A report from
Tim Kosse <tim.kosse@filezilla-project.org>.
(vsftpd-3.0.3pre1)
- Enable ECDHE, Tim Kosse <tim.kosse@filezilla-project.org>.
- Default cipher list is now just ECDHE-RSA-AES256-GCM-SHA384.
- Minor SSL logging improvements.
- Un-default tunable_strict_ssl_write_shutdown again. We still have
tunable_strict_ssl_read_eof defaulted now, which is the important one to prove
upload integrity.
(vsftpd-3.0.3pre2)

Fix build on DragonFly BSD. From TimH on pkgsrc-users.

Update to 2.3.4, based on a patch by Stephan Tesch
<s.tesch@science-computing.de> on pkgsrc-users.

- Avoid consuming excessive CPU when matching filenames to patterns. Thanks to
Maksymilian Arciemowicz <cxib@securityreason.com>.
- Some bugfixes from Rapha
no apparent security impact.

At this point: v2.3.3 released!
===============================

- Fix compile. Extreme suckage.

At this point: v2.3.4 released!
===============================

Updated net/vsftpd to 2.3.2

Changes since 2.0.7

- Remove .postlogin.c.swp (thanks Kaibin Li <kbli@fortinet.com>)!
- 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 <it@exanto.de>.
- Replace spaces in xferlog with underscores, report from
Michael Wittauer <michael.wittauer@sonydadc.com>.
- 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 <fbulk@mypremieronline.com>.
- 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 <pabel@fexcodcc.com>.
- 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
Ren
- 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 <mnagy@redhat.com>.
- 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.

At this point: v2.1.0 released!
===============================

- Apply Tavis' RLIMIT_NOFILE trick in the twoprocess model's initial
unprivileged child.
- Fix build error due to __NR_utimes.
- Ugh. Can't use RLIMIT_NOFILE in the SSL case because the process later
receives data transfer fd's via recvmsg(). It's a total shame because doing
the SSL handshake under even lower privs would be a real boost.
(v2.1.1pre1 here)
- Fix some declarations occuring in the middle of a block; broke older more
strict compilers.
- Handle the case where libcap is now libcap.so.2; fixes build on my new
Ubuntu 9.04.
- Enhance 522 error message to point to require_ssl_reuse option.
- Fix NASTY regression whereby data transfer timeouts would fire incorrectly
under SSL transfers. In addition, the transfer rate caps were not working
under SSL transfers. Reported by several people.
- Use the login delay machinery for userlist-based denials too. Thanks to
Tomas Hoger <thoger@redhat.com> for the patch.
- Fix another tedious regression whereby absent per-user config files were
causing a session fail rather than being gracefully ignored.
- Use the somewhat new CLONE_NEWPID / CLONE_NEWIPC to provide more isolation
in the vsftpd low-priv processes (CLONE_NEWNET pending).
- Use RLIMIT_NPROC to disallow fork()ing etc. in processes that do not need
to create new ones.
- Add "isolate" config flag to disable the new weird clone() flags if
necessary.

At this point: v2.1.1 released!
===============================

- Fix compile error in sysdeputil.c on some Linux systems.

At this point: v2.1.2 released!
===============================

- Fix compile on systems with no RLIMIT_NPROC, oops.
- Change some unsigned int to socklen_t's to avoid warnings on various
platforms, e.g. AIX.
- Add some syscall constants to ptracesandbox.c to fix the build on systems
with 2.4 kernel headers.
- Look for libs in /lib64 and /usr/lib64 too (Fixes Fedora 11 x86_64 compile).
- Fix EACCES mapping, thanks Solar Designer <solar@openwall.com>.
- Dont emit a bogus "OOPS: " message upon a QUIT, report from Solar Designer
<solar@openwall.com>.
- Tweak example vsftpd.conf to add commented out chroot_local_user=YES,
from Ivan I. Grushin <mcgru@intrice.ru>.
- Where available, use CLONE_NEWNET to isolate the untrusted processes so that
they can't do arbitrary connect() and instead have to ask the privileged
process for sockets. Moderate code disturbance - hope for no breakage :-/
- Disable implicit activation of one_process_model so that an anonymous setup
can benefit from the no-network isolation of the unprivileged process (where
available).
(vsftpd-2.2.0pre1)
- Call pam_get_item(PAM_USER) after authentication in case a PAM module
remapped the username. Based on a patch from John McNair <john.mcnair@ihg.com>.
- Apply a couple of IPv6 fixes from Corinna Schultz <corinna.schultz@gmail.com>,
particularly when MS operating systems are talking on link local addresses.
- Handle the error case for accepting a PASV connection in the two process
model properly.
- Pull in a couple of minor tidyup patches from Openwall.
- Add "-o" command line option to specify option, e.g. vsftpd -olisten=NO. Also
respect ordering with respect config files, e.g.
vsftpd -olisten=NO /etc/vsftpd.conf -olocal_enable=NO
Inspiration from Solar / Openwall.
(vsftpd-2.2.0pre2)
- Revert listen to be "NO" by default and also set max_per_ip / max_clients
to 2000 / 50 as a default. Thanks to Solar.
- Sanity check for admin: check config files are regular files.
- Error out if opening the per-user config file gives an error other than
ENOENT. Thanks Solar (who is on fire today ;-)
(vsftpd-2.2.0pre3)
- Apply some typo fixes from Solar.
- Error out on read() errors when reading config files.
(vsftpd-2.2.0pre4)
- Add tunable_isolate_network to parseconf.c, thanks Stefan Pfetzing
<dreamind@dreamind.de>.
- Don't try and use CLONE_NEWPID etc. if we get EPERM -- may happen even to
root if using linux-vserver. Also thanks to Stefan Pfetzing
<dreamind@dreamind.de>.
- Couple of typo tweaks from Cristi Terpea <cristi.terpea@fortech.ro>.
- Change // style comments to /* style.
- Fix pointer aliasing issue in new PAM_USER item support, thanks to Solar.

At this point: v2.2.0 released!
===============================

- Apply patch to set SSL context timeout to maximum, from Tim Kosse
<tim.kosse@filezilla-project.org>. Should prevent data connection failures
after a long transfer or idle period.
- Apply async-safety signal tweaks from Solar.
- Fix crash regression with the pasv_address option enabled.
- Typo fix and look for libnsl in /lib64, from Robby Workman
<rworkman@slackware.com>.
- When asking the client to send us a cert, make sure we broadcast some suitable
certificates. Fixes compatibility with the z/OS FTP client when
tunable_ssl_request_cert=YES.
- Rip out the silly "cached time" concept. Simplifies things and fixes
incorrect transfer time bug reported by Rajeev V. Pillai. Explicitly pass around
the cached current time in seconds in the one place that needs to avoid
repeated gettimeofday() calls (directory listing).
- Do the login fail delay in the parent process for cases where we checked
a username / password.

At this point: v2.2.1 released!
===============================

- Change "File receive OK." to "Transfer complete." to placate some broken
clients. Thanks Holger Kiehl <Holger.Kiehl@dwd.de>.
- Fix erroneous "child died" upon FTP client connect, when under load. Awesome
thanks to Holger Kiehl <Holger.Kiehl@dwd.de> for running diagnostic tests on
his live server.
- Boot the session if an overly long line is encountered.
(vsftpd-2.2.2pre1)

At this point: v2.2.2 released!
===============================

- Add extremely simply HTTP support. It's very experimental, ignorant of HTTP
protocol and headers, and likely has all sorts of other issues. The use case
it might satisfy is if you need to serve simple static unathenticated content
with large levels of paranoia.
- Fix port_promiscuous breakage. Report from Soeren <soeren84@fastmail.net>.
(v2.3.0pre1)
- Minor FAQ update.
- Use a larger address space limit if using text_userdb_names=YES
- Always use CLONE_NEWNET if possible when in HTTP mode.
- Change REST + STOR so that it's possible to overwrite part of file without
truncating it.
(v2.3.0pre2)
- Boot the session if we see a USER where encryption was required. May prevent
the transmission of plaintext passwords by buggy clients. Idea from
Marcin Hlybin <marcin@rootnode.net>.
- Fix failure to transmit a large ASCII file over SSL, if it contains \n -> \r\n
fixups.

At this point: v2.3.0 released!
===============================

- Fix silly regression re: log files being overwritten from the start.
- Rename a few file-open functions to make it clearer what they do.

At this point: v2.3.1 released!
===============================

- Argh! Fix version number.

At this point: v2.3.2 released!
===============================

regen for missing patch-ae.

Updated net/vsftpd to 2.0.7 - needed for recent FileZilla to with with SSL

v2.0.5

- Apply fix for O_NONBLOCK vs. XFS DMAPI filesystem. Thanks to Sudha Srinivasan
<sudhas@sgi.com>.
- Fix build warnings exposed by my upgrade to Fedora Core 5 / GCC4.1.1.
- Be more honest in FEAT response if PORT or PASV are disabled! Reported by
Charles Honton <chas@honton.org>. Allows MS Explorer to get the transfer mode
correct.
- pam_pwdb.so -> pam_unix.so in example PAM file. Thanks to
Rhodes, Colin <colin.rhodes@airways.co.nz>.
- Add FAQ issue regarding "chroot fails with SSL" - in fact, sshd is being hit
here instead ;-)
- Minor man page doc tweaks.
- Tiny bit of paranoia in privops.c.
- Revert change to reject anonymous logins before asking for password. This
fixes complaints about IE not showing the FTP login dialog.
- Change SSL certificate load to cater for chaining too.
- Added delay_failed_login and delay_successful_login to help limit resources
taken by brute force attacks.
- Kick session after a few login fails. Allows IP blocking solutions to be more
immediately effective.
- Replace setenv() with more portable putenv(). First part of Solaris fix.
- Replace tm_gmtoff usage with timezone and daylight. Second part of Solaris
fix.
- Set PAM items TTY and RUSER if possible.
- OpenBSD build warning fixes.
- So, timezone and daylight are not available on BSD, so redo the whole TZ
thing again. Should use only very portable constructs now.

v2.0.6

- Fix delay_failed_login typo. Oops.
- Patch the getcwd and readlink sysutil helpers to reflect that they wouldn't
like a 0-sized buf. No caller is affected. Thanks Ilja van Sprundel
<ilja@suresec.org>.
- Allow a (fake) reauth as the same user as the logged in user. Should resolve
.NET related report from Sabo Jim <Jim.Sabo@thomson.net>.
- Tweak from Lucian Adrian Grijincu <lucian.grijincu@gmail.com> to take
unnecessary port calculations out of a loop.
- Fix byte I/O accounting in the error path of do_file_send_rwloop, thanks to
<echen@siac.com>.
- Don't log FireFox's attempts to RETR directories! Reported by
Nixdorf, Tim <tnixdorf@dnps.com>.
- Fix STOU sending the same 150 status line twice - oops! Reported by
<yamazaki@iij.ad.jp>.
- Fix xferlog format for virtual (guest) users, reported by Andy Fletcher
<andy@withnail.org>.
- Fix bug with empty user list file and userlist_deny=NO. Reported by
Marcin Zawadzki/GlobalVanet.com <marcin.zawadzki@globalvanet.com>.
- Pretend we have proper UTF8 support and respond positively to OPTS UTF8 ON.
Thanks Stanislav Maslovski <stanislav.maslovski@gmail.com>.
- Add control over the file permissions used in the chown()ing of anonymous
uploads: chown_upload_mode (default 0600 as before). Suggestion from
An Pham <apham@medforcetech.com>.
- Do a retry getting the active ftp socket in vsf_privop_get_ftp_port_sock();
should help buggy Solaris systems. Reported by Michael Masterson
<mjmasterson@xo.com>.
- Add debug_ssl option to dump out some SSL connection details.
- Use code 522, not 521, to indicate that the server requires an encrypted
data connection. Still does not seem to coax lftp to retry :(
- Recognize OPTS pre-login.
- A whole ton of SSL improvements, including ability to force requirement of
a client cert; data and control channel client cert cross checking. Ability
to require fully valid / authentic client certs. No cert-based auth yet.
- Change my e-mail to my GMail account.

v2.0.7

- Fix finding libcap for the link on Slackware systems, thanks to Roman
Kravchenko <roman@atech.lv>.
- Fix build on Solaris 2.8 due to non-standard C, thanks to IIDA Yosiaki
<y-iida@secom.co.jp>.
- Fix man page typo, thanks Matt Selsky <selsky@columbia.edu>.
- Bring the PASV listen() into the bind() retry loop to resolve a race under
extreme load. Thanks to Curtis Taylor <cjt@us.ibm.com>.
- Enhance logging for debug_ssl.
- Shutdown the SSL data connections properly. This prevents clients such as
recent FileZilla from complaining. Reported by various people.
- Add option to enforce proper SSL shutdown on uploads. Left it off after much
agonizing because clients are so broken in this area.
- Add option to delete failed uploads.

Improve linkage but not using the crappy shell script from vsftpd,
which doesn't work correctly e.g. on Solaris. Make PAM optional,
but since the option is on by default, nothing changes.
Fix compilation on Solaris based on input from Stefan Pfetzing
in PR 33494.

Update to 2.0.4, based on 2.0.1 update from Ove Soerensen in PR 26811.
Add ssl (default off) and tcpwrappers (default on) options.

Changes:

- Improve logging (log deletes, renames, chmods, etc. as requested by users).
- Add no_log_lock to work around Solaris / Veritas locking hangs.
- Add EPRT, EPSV, PASV and TVFS to FEAT response.
- Implement use of MDTM to set timestamps.
- Recognize FEAT prior to login.
- Add OpenSSL (AUTH TLS / SSL) support for encrypted control and data
connections! Hurrah.
- Increase max size of .message files to 4000 characters, thanks to Eric
Pancer for the report.
- Add easy builddefs.h ability to disable PAM builds even when PAM is installed.
- Report vsftpd version in STAT output.
- Add REFS file.
- Change parent<->child socket comms from DGRAM to STREAM for increased
reliability. The main benefit is should the parent be killed (or crash out)
then the child won't block on a read() that will never return.
- Make str_reserve reserve space for the trailing zero as well, so we don't
cause a reallocation if we exactly fill the buffer.
- Optimize the sending of strings over the parent<->child comms links.
- Improve the build system so tcp_wrappers, PAM and OpenSSL can be forcibly
compiled out.
- Fix vsftpd.conf.5 typos, thanks to Dmitry V. Levin
- If trans_chunk_size is between 1 and 4096, use 4096 rather than ignoring
totally. Thanks to Brad
- Lose Makefile.sun and README.solaris special cases.
- Add SSL / TLS info to SECURITY texts.
- Add README.ssl
- Add documentation for new SSL options to vsftpd.conf.5.
- Add support for CWD ~ (and in general support ~ at start of any filename).
Also support stuff like ~chris/pics, if tilde_user_enable=YES is set. Note that
all of this is for very very broken clients :-(
- Fix compile warnings.
- Update INSTALL with (recent) OS X as a working platform.

At this point: v2.0.0 released!
===============================

- Add -lcrypto for the SSL build; needed for some systems! Thanks to Nelson
Chang
- Oops; fix session bale out if an empty length password is given.
- Fix build on Fedora Core 2 (-lcap cannot seem to find /lib/libcap.so).
- Fix vsftpd.conf.5 man page error in "ssl_sslv3", thanks to Etienne Chevillard
- Clarify licensing: I allow linking of my GPL software with the OpenSSL
libraries. Thanks to Jonas Bofjall
- Add COPYRIGHT.
- Fix build on OpenBSD, FreeBSD, probably NetBSD too (they aren't SuSv2
compliant; timezone should be a variable not a function).
- Fix build where PAM build is enabled but PAM headers are missing.
- Fix build on RHEL3 (remove errant include from twoprocess.c).

At this point: v2.0.1 released!
===============================

- Fix FAQ typo, thanks to Jose Santiago Oyervides Gonzalez
- Emit data transfer status messages (success / failure) after flushing and
waiting for the full data transfer to reach the client. This should help work
around buggy FTP clients such as FlashFXP, which is known to truncate files
incorrectly.
(v2.0.2pre1)
- Make str_empty actually allocate an empty string.
- Change the ASCII receive code to ONLY rip out \r if it is just before a \n;
someone finally complained about this.
(v2.0.2pre2)
- Enable AIX Large File Support #define from Tomas gren
- Add a couple of FAQ entries.
- Fix time delta code areas to cope with negative deltas, which will occur
if the clock is adjusted backwards. Thanks to Andrew Anderson
for a great report.
- Fix "errno" checks to be robust in multiple places; previously, calls to
failing library calls could be made inbetween the original library call and
the "errno" reads. Thanks to Andrew Anderson for a great
report.
- Make bandwidth limiter work with SSL data connections.
(v2.0.2pre3)
- Note that the SSL / bandwidth limiter bug fixed a much more serious bug:
SSL data connection dropouts after data_connection_timeout seconds.
- Typo fixes.

At this point: v2.0.2 released! (need to get the SSL dropout fix out)
=====================================================================

- Document what regex expressions are supported in the man page.
- New settings rsa_private_key_file and dsa_private_key_file to allow
separate files for the certificates and private keys.
- Initial, simple fix for timed out processes not exiting when SSL is in use.
Better fix (which reports timeout to client properly) to follow.
- Add which setsockopt option failed to die("setsockopt") calls.
- Fix when running on recent OpenBSDs - OpenBSD change broke vsftpd. Lower
linger timeout from INT_MAX to 32767 (SHORT_MAX). Reported by
Ewoud van der Vliet and Ed Vazquez (v2.0.3pre1)
- Fix error with IPv4 connections to IPv6 listeners and PORT type data
connections when connect_from_port_20 is set. RedHat bugzilla 134541. Reported
by Joe Orton, Radek Vokal and Andreas Kupfer
- Remove vsf_sysutil_sockaddr_same_family (unused).
- Support protocol 1 (IPv4) in EPRT.
- Add ssl.c to AUDIT.
- Allow config file to use "ssl_ciphers=" to use default OpenSSL cipher list.
- Allow "EPSV 1" to mean IPv4 EPSV.
- Report dummy IP but correct port with IPv6 / PASV.
- Handle SSL_WANT_READ and SSL_WANT_WRITE retries in SSL_read and SSL_write;
fixes SSL upload failures when data timeouts are in use with some clients.
Specifically, I used the test case FileZilla 2.2.12a on Windows XP. Reported
by Lee Lawrence (using CuteFTP and BackupEdge) and
Christian DELAIR (using lftp, FileZilla and
SmartFTP). Thanks to these two people for valuable help.
(v2.0.3pre2)
- Implicitly disable connect_from_port_20 and chown_uploads when a non-root
user is using run_as_launching_user.
- Add force_anon_logins_ssl and force_anon_data_ssl for a fully SSL secure
anonymous-only solution (useful when you don't have root access and a range
of acceptable anonymous passwords as credentials).
- Use SSL BIO callbacks to fix data connection timeout checks; the checks
weren't all occurring promply.

At this point: v2.0.3 released! (need to get about three imporant fixes out)
============================================================================

- Add explicit "This FTP server does not allow anonymous logins" message.
- Add paranoid checks to sysutil.c for large values / lengths.
- Fix incorrect comment about ASCII and SIZE in the vsftpd.conf example.
- Load per-IP config files earlier; allows more settings to be tuned on a
per-IP level. Suggested by Reber Tobias
- Fix MDTM on non-existant files. Reported by Ken A
- {} regex fix so that {*} correctly matches everything. Reported by
Tom Van de Wiele
- Add "mdtm_write" option to disable MDTM being able to set file timestamps.
- Fix HPUX build, thanks to Kevin Vajk
- Add optional file locking support via lock_upload_files (default on).
- Apply LDFLAGS patch from Mads Martin Joergensen
- Add pasv_addr_resolve option to allow pasv_address to get DNS resolved once
at startup.
- Apply patch to fix timezone issues (caused by chroot() interacting badly with
newer glibc versions). Thanks to Dmitry V. Levin and
Mads Martin Joergensen

At this point: v2.0.4 released!
===============================

Add RMD160 digests.

Updated to version 1.2.2.

Changes:

- remove superfluous .if around BUILD_DEFS
- drop maintainership, i don't really use the package anymore
- XXX: this package doesn't compile on non-IPv6 enabled operating systems

1.2.2:
======
- Fix FreeBSD 5.1/5.2 issue with time_t being long long on that platform.
- Tweak vsftpd.conf.5 to avoid automated mails from ESR ;-)
- Add -v flag which just outputs the version and exits.
- Fix nasty issue resulting in listener instability under extreme load
  (root cause was re-entering malloc/free).
- Fix build with modern glibc-2.3 and no libcap on Linux.
- Fix 64-bit file support on Solaris.
- Add initial support for running as the user which launched vsftpd,
  i.e. no root needed. Warning - easy to create insecurity if you use
  this without knowing what you are doing.
- For above run-as-launching-user support: make CDUP re-use CWD code
  so that deny_file of *..* is useful.
- Attempt fix of 64-bit file support on FreeBSD (may need another go).

Update to version 1.2.1.

Changes:

- Apply NetBSD patch to sysdeputil.c to activate a few features. Thanks to
  Lubomir Sedlacik <salo@netbsd.org>.
- Apply fix for broken clients that terminate commands with \r\r\n. Thanks
  to Andrey Chernomyrdin <andrey@excom.spb.su>.
- AIX send_file support, thanks to Tomas Ogren <stric@ing.umu.se>.
- Fix typos in vsftpd.conf.5, thanks to SEKINE Tatsuo <tsekine@sdri.co.jp>.
- Simple -F flag support to LIST and NLST. Needed for some broken clients.
- Add simple ? wildcard in pattern matching.
- Make pasv_min_port and pasv_max_port work if they are the same value.
  Thanks to Marvin Solomon <solomon@cs.wisc.edu>.
- Paranoia: ignore user_config_dir if username has a / in it.
- Implement stub ALLO command to keep busybox/ftpput happy.
- Implement REIN, ACCT and SMNT stubs.
- Implement FEAT along with an OPTS stub.
- Implement STAT (no-args version).
- Implement STAT (file/dir).
- Add very simple access control via hide_file and deny_file. These should
  NOT be used for securing content as they are very dumb!  Filesystem
  permissions are still the recommended way for securing important content.
- Allow unsetting of string values with option= (i.e. blank).
- Default virtual users to being chroot()'ed to the guest_user's home
  directory, if virtual_use_local_privs is not set.
- Add support for "user_sub_token", where you can set the home directory
  of guest_user to "/home/virtual/$USER", and "user_sub_token" to "$USER"
  to have a root directory auto generated based on username logging in,
  e.g.  fred logs in and gets chroot()'ed in /home/virtual/fred.
- Fix bug in str_replace_text if replace token matches at end of string.
- Recognize P@SW as PASV; works around an SMC router bug.
- Accept an async ABOR sequence if it arrives via non-urgent data.  Fixes
  issue with Cisco routers. Thanks to Eddie Corns <E.Corns@ed.ac.uk>.
- Implement simple {,} support in pattern matcher (nested not handled).
  Handy to use with hide_file and deny_file options.
- Fix port range with pasv_min_port and pasv_max_port to use the full range
  (the upper limit wasn't being used very often!).
- Activate SO_REUSEADDR on passive listen sockets - makes servers with
  restricted port ranges much more useable!
- Add secure_email_list_enable, to provide simple anonymous password control.
  For some cases, it's better than the hassle of virtual users. Idea thanks
  to Malcolm O'Callaghan, <mjo@stamps.com>.
- Add some FAQ entries.
- Fix issue with failure to call openlog() before using tcp_wrappers. Part
  of RH bugzilla #89765. (The more serious part was fixed with v1.2.0).

Updated to 1.2.0.

- take over maintainership, MAINTAINER is not reachable on his mail anymore
  (non-existent domain).

Changes:

Logging has been enhanced, including syslog support.  IPv6 support has been
added.  STRU, MODE, STOU, HELP, and SITE HELP have been implemented.  Better
control of which commands to allow has been added.  pam_session support has
been added.  Error messages have been improved.  There are lots of bugfixes
and new configuration options.

- Eliminate crypt() not defined warning.
- "grep -q" is not standard to redirect to /dev/null instead.
- Make banned_email_file work second time around.
- Add force_dot_files to work around broken clients. The behaviour when
  enabled is very wu-ftpd like.
- Implement SITE HELP - should work around IE bug?
- Update README, vsftpd.conf with references to read the manual page!
- Log revamp: add dual_log_enable to log to xferlog AND vsftpd.log.
- Log revamp: add syslog_enable to log vsftpd.log to syslog().
- Add "background" option to background the listener process.
- Fix warning is vsftpd.8 man page, Bill Nottingham <notting@redhat.com>.
- Fix tcp wrappers support to NOT emit loads of Bad file descriptor messages
  to the system log.
- Add ability to make bandwidth limiter smoother by using e.g.
  trans_chunk_size=8192.
- Add ability for virtual users to use local privs non anon privs, via
  virtual_use_local_privs=YES.
- Fix sendfile() fallback on FreeBSD, thanks to Adam Stroud
  <adstro@stny.rr.com>.
- Add pam_session support, as well as utmp and wtmp logging for local logins
  (when using a PAM build). Tested pam_limits maxlogins works.
- Ensure the source IP address for PORT connects is always the same as the
  control connection local IP address. Previously it was not when NOT using
  connect_from_port_20 in the presence of multiple local IP addresses.
- Oops - make max_per_ip and max_clients work with the two process model
  when both connect_from_port_20 and chown_uploads are false.
- Initial IPv6 support (EPSV only).
- Add EPRT support to IPv6.
- Fix "ls .file" to list .file even if the ls -a flag is not present. Noted
  by and thanks to Sean Millichamp <sean@enertronllc.com>.
- Better error messages for config file parse fail: include setting name.
- Fix bug in str_split_text where text is greater than 1 character long!
- Make it build on Solaris8 - switch from utmp to utmpx and handle missing
  LOG_FTP.
- Always check for VSFTPD_LOAD_CONF environment variable.
- Implement HELP properly (should help broken clients).
- Fix FreeBSD build (no utmpx.h, so disable feature).
- Fix chown_uploads.
- "Guess fix" for FreeBSD reported bug. I reckon FreeBSD is returning -EINTR
  from a blocking close but still closing the fd, despite the error return. So
  cater for this. Reported by Drew Vogel <dvogel@intercarve.net>.
- Add download_enable and dirlist_enable. Useful in conjunction with the
  per-user config stuff.
- Add chmod_enable.
- Implement STRU and MODE for _old_, broken clients!
- Log connects.
- Fix 500 OOPS with chown_uploads and an APPE command.
- Improve some error messages: die -> die2 for more information.
- Repair max_per_ip (problem comparing IPv4 addresses).
- Make chown_uploads work with virtual users.
- Chmod files to 0600 before chown_uploads kicks in.
- Add STOU support.
- Add cmds_allowed config parameter.
- Add some FAQ entries.

Initial import of vsftpd-0.9.1

vsftpd is an FTP server, or daemon. The "vs" stands for Very Secure. Obviously
this is not a guarantee, but a reflection that I have written the entire
codebase with security in mind, and carefully designed the program to be
resilient to attack.

Recent evidence suggests that vsftpd is also extremely fast (and this is
before any explicit performance tuning!) In tests against wu-ftpd, vsftpd
was always faster, supporting over twice as many users in some tests.

Package provided by Jacek Latos <vaneth@krasnik.org> in pkg/13208;
minor modifications by me.
