0.0.1 initial versioned tarball released
----------------------------------------
- Added "-ldl" to LIBS to get linking to work on RedHat6.1
- Add RedHat6.1 on list of tested platforms :)
0.0.2 packaged
--------------
- Emit version in greeting string
- In PORT command, reject numbers <0 or >255. Problem noted by Solar Designer,
- Allow an option AND a path for LIST/NLST, e.g. "LIST -al /pub". Reported by
Bill Nottingham <[email protected]>, using ncftp. Further noted by Colin
Hogben <[email protected]> using emacs and James Antill <[email protected]>.
- Don't prepend directory path for LIST (but still so for NLST). Noted by
Colin Hogben <[email protected]> and Ingo Luetkebohle <[email protected]>
- Fix problem listing non-existant or unreadable directories - just return
a blank listing rather than an error. Problem noted by Martin Sillence
<[email protected]>, using squid.
- Fix KDE's downloads (via KFM), it was using the "SIZE" command which I had
not implemented. Reported by Simon Dales <[email protected]> and Jo Dillon
<[email protected]>. Apparently implementing SIZE also fixed lftp's download
time estimator, reported by Ingo Luetkebohle <[email protected]>
- Remove abornal_exit() from utility.c
- Fix so we don't write "500 OOPS: child died" upon QUIT. Reported by Solar
Designer, <[email protected]> and Tim Bagot <[email protected]>
0.0.3 packaged
--------------
- Oops: fix so we don't emit a status 150 mark unless we actually got a
connection from the client (stops some clients hanging trying to list an
inaccessible directory)
0.0.4 packaged
--------------
- In verbose directory listing, report symlink targets. Use the traditional
syntax of: "link_name -> target_path"
- Damn netscape! The comma in the response text to PASV confused it, so it
had to be removed. Discovered with tcpdump!
- Don't require clients to redo PORT or PASV if a RETR or STOR fails due
to inability to open/create file. Fixes Netscape symlink navigation problem.
- Fix for listing absolute paths with only one /, e.g. "ls /.message" was
failing
0.0.5 packaged
--------------
- Remove README.ftpproto
- Add SECURITY/OVERVIEW
- Add SECURITY/DESIGN
- Note that as a security tweak, we should lose more privs if we're configured
for anonymous only logins (TODO)
- Add SECURITY/IMPLEMENTATION, SECURITY/TRUST, but nothing in them yet.
- Convert str.c to vsf_sysutil_*. This leaves the following to do:
checkauth.c, main.c, postprivparent.c, privparent.c, privsock.c, utility.c
- Convert privparent.c to vsf_sysutil_*.
- Create BUGS and move existing listed bugs from TODO into this new file
- Add parseconf.h, parseconf.c to handle parsing of a config file (work in
progress)
- Fix change_full_credentials() in utility.c, to always chdir() even if we
are not going to do a chroot()
- Rename get_random_byte() to vsf_sysutil_get_random_byte(), and move from
utility.c to sysutil.c
- Create new file secutil.c, move change_full_credentials() to it and rename
- Convert utility.c to vsf_sysutil_*.
- handle_local_login(): don't look up username; common_do_login() does it
- implement different tunable umask() values for local/anonymous users
- implement SITE UMASK
- implement SITE CHMOD
- whoops! allow non-anonymous users to overwrite files with STOR
0.0.6 packaged
--------------
- SECURITY: when in anonymous-only mode, reject usernames that aren't the
anonymous usernames. This is hoping some FTP clients will be stopped from
sending a cleartext password. Idea from Gerald Teschl <[email protected]>.
- Decided to put "telnet strings" on the back burner :)
- Sprinkling of static in main.c
- Complete parseconf.c config file parsing and plug it into main.c
- Convert main.c to vsf_sysutil_*. This leaves
checkauth.c, postprivparent.c and privsock.c
- Now we have runtime config, make compiled in defaults extra paranoid
- Implement "tunable_anon_world_readable_only" to only serve publicly
readable files anonymously
- Add sample "vsftpd.conf"
- Eww - missing "return" in parseconf.c
- Move ASCII mode transfers out of critical section in TODO
- parseconf.c: if an integer starts with "0", treat it as octal
- Ban "SITE CHMOD" if !tunable_write_enable
- Wrote SECURITY/TRUST
- Wrote SECURITY/IMPLEMENTATION, probably more to come
- Update INSTALL
- Add "tunable_nopriv_user"
- Update parseconf.c with the two latest new config variables
- Add sysdeputil.h, sysdeputil.c for system specific facilities, i.e.
capabilites, authentication.
- Lose checkauth.c,h - they moved into sysdeputil.c,h
- Lose config.h - it moved into sysdeputil.c
- Convert postprivparent.c to vsf_sysutil_* (leaves privsock.c)
- Convert privsock.c to vsf_sysutil_*. All done, yay!! :)
- D'oh! Missing "!" in postlogin.c refused to server publicly readable files:)
- Fix chown() of uploaded files (broken initialization order in main())
- Add SPEED, and fill it with wild speculation
- Rename distribution directory "vsftpd-x.x.x" (note the added "d")
0.0.7 packaged
--------------
- Build with -O2
- Fix "uninitialized" warnings -O2 exposed - the one in capabilities setup
could be nasty!
- Nail warning in vsf_sysutil_sendfile(). We're now "-Wall warning free"
- Build with -Werror to signal intent to _stay_ warning free
- A few int -> long in the area of file sizes and offsets
- Remove comma's at end of enum lists (-pedantic caught it)
- Impact from fixing warnings caused by -pedantic
- Date format %e -> %d in date display, %e isn't everywhere
- Paranoia in vsf_sysutil_malloc()
- Clean up interface to substring searching in str.c
- Cleanups in str.c
- Squash most "unsigned<->signed" conversions exposed by -Wconversion
- Lose "-g" to CFLAGS; after all we're bug-free now ;-)
- Add "AUDIT"
- Fix up a bunch of potential 64-bit issues (maybe >2Gb files will work on
64-bit platforms now, no way to test)
- Implement PR_SET_KEEPCAPS support for 2.2.18+ and 2.4.0+ kernels
- In sysdeputil.c, change NULL -> 0 to help Solaris build problem
- Repair vsf_sysutil_sendfile() and the caller
- Logging: log the username
- Logging: don't log "//" as start of filenames under certain conditions
- Logging: log the date. Logging is almost useful now!
- Logging: log MKD commands too; they are used in anon ftp a fair bit
- Take the trouble to look into partial reads/writes. Looks like we are safe.
- vsf_sysutil_read and vsf_sysutil_write now hide EINTR and retry
- Replace some vsf_sysutil_{read,write} usage with
vsf_sysutil_{read,write)_loop which handles partial reads and writes
- Implement a sendfile() replacement for systems which lack it
- Implement runtime checking for system specific Linux stuff, i.e.
prctl(PR_SET_KEEPCAPS). This is inspired by RedHat7.0 headers claiming to
be a 2.4.0 kernel, but actually you are running on 2.2.x! :-(
- Strip the build executable at link time
0.0.8 packaged
--------------
- A few incorrect sizeof()'s in postlogin.c, thanks to Antonomasia
<[email protected]> for noting these.
- Decide that ASCII support isn't too important for now (waiting for users to
demand it). Also decide that ABOR is a must :( Thanks to Zach Brown
<[email protected]> for the discussion.
- More TODO items thanks to Stephen White <[email protected]> - 2.0.x
issues.
- Provide a definition for SHUT_RDWR in sysutil.c, not all systems have that
definition yet. Thanks Stephen White <[email protected]>.
- Tidy privparent.c
- Decide ASCII _is_ quite important, thanks Solar ;-)
- Bit of extra paranoia in sysutil.c: don't call mem*() if size == 0
- Tidy str.c
- Command line: if vsftpd has an argument, it is a path to a config file.
- Set TCP_NODELAY on command stream
- Don't lseek() for RETR in common case with REST set to 0
- Correct error code for transfer after succesful connection (425 -> 426)
- ABOR support. Bah.
- APPE support (why not, it was trivial). Putting off ASCII support ;-)
- Add ASCII transfer support. Bah.
- Tidy up sysutil.c, fix breakage in read_loop and write_loop.
0.0.9 packaged
--------------
- Remove ".message" from distribution. Thanks Mitchell Blank Jr
- Note where I can get some load testing software, thanks to Dan Kegel
<[email protected]>. I'll do that soon because I hope to waste wu-ftpd.
- Fix an Alpha build warning and check return value from final pam_end().
Reported by Solar Designer <[email protected]>.
- Add xinetd.d/vsftpd, from Kurt Seifried <[email protected]>.
- Integrate comments/fixes into SECURITY documentation, thanks to Antonomasia
- SECURITY: default tunable_chroot_local_user to 0, because it is dangerous to
give users write access to the filesystem root (think of opening trusted
files relative to the root). Thanks again Solar Designer
- Add "make install" target. Currently it is minimal!
- Clearer error message if vsftpd is started manually. Suggestion from
Tom <[email protected]>.
- Report futuristic or old (>6 months) dates in a different format, showing
the year like /bin/ls does.
- Add KERNEL-2.4.0-WARNING. Whoo-hoo. Why do all my non-trivial programs seem
to trigger kernel bugs?
- SECURITY: refuse to allow anonymous logins if some bonehead has configured
the anonymous ftp user with write access to the ftp root.
- Fix ASCII downloads so that \n UNCONDITIONALLY maps to \r\n. This behaviour
is now consistent with wu-ftpd and results in simpler code.
- Fix ASCII uploads to not to fail to strip some \r characters. Noted by
Mitchell Blank Jr <[email protected]>.
- Add TODO items: log transfer rate and anonymous password. Andrew Anderson
0.0.10 packaged
---------------
- Remove errant #include <sys/sendfile.h> from sysutil.c. Noted by Jan-Frode
Myklebust <[email protected]>
- Use gettimeofday(2) not time(2), for better resolution.
- Add transfer rate to the log
- Add <limits.h> to sysutil.c, spotted by Kevin Vajk <[email protected]>.
- Spell "LICENSE" correctly: Kevin Vajk <[email protected]>.
- Use fcntl() for locking instead of flock() because it is much more standard.
flock() usage noted by Kevin Vajk <[email protected]>.
- Use more portable IPPROTO_* instead of SOL_* (IPPROTO_IP, IPPROTO_TCP).
Thanks to Neil Blakey-Milner <[email protected]> porting to FreeBSD.
- Start of Solaris port, thanks to Kurt Seifried <[email protected]>
for access to a Solaris 8 box.
- Portability fix: include <netinet/in_systm.h> before <netinet/ip.h>.
- Port to Solaris 8: new directory port. New file porting_junk.h. New file
solaris_bogons.h
- Add vsf_findlibs.sh to cater for different platform link requirements. Now
builds on Solaris and Linux with "make".
- struct sockaddr casts to kill Solaris warnings.
- sysdeputil.c: remove unused variable warnings.
- sysutil.c: use _exit() instead of exit() to avoid libc doing stuff on exit.
Fixes segfault reported by Joshua Hill <[email protected]>.
- Add BENCHMARKS. Many thanks to Andrew Anderson <[email protected]>.
- Fix disconnect/crash if SIGURG received whilst blocking on command stream.
- Update INSTALL with more platforms.
0.0.11 packaged
---------------
- Brag about performance in README. And why not.
- Better bail-out message if the "ftp" anonymous user isn't found
- Better bail-out message if the secure chroot directory isn't found
- Introduce tunable_one_process_model and start work on it
- Fix rare segfault on exit - race leading to infinite stack recursion
- Don't bail out if we didn't get an argv[0]. Who cares? Noted by Kurt Seifried
- Change logged date format to include the year.
- Add option to log in standard (wu-ftpd like) "xferlog" format.
- Cater for sendfile() returning EINTR in sysdeputil.c
- Use SO_LINGER on data sockets, to get accurate transfer rates!
- Cater for an interrupted blocking close()
- Tuning: eliminate 3 mprotect(), 1 munmap() and 1 mmap() system call per
command read.
- Prevent infinite loops calling sendfile(). Two bugs - we needed to check
the sendfile() return for 0 (doh!!) and also, we sometimes did lseek() on
a file, to beyond its end. Thanks to Daniel Veillard <[email protected]>
for reporting.
- Tuning: cache fd's for /etc/passwd and /etc/group to avoid syscalls.
- Tuning: "assist" the get*uid(), get*nam() calls to not make lots of useless
syscalls, if /etc/group and /etc/passwd are missing. Thanks to Daniel Veillard
<[email protected]> for reporting.
- Use SO_LINGER timeout of 5 mins; INT_MAX seemed to do nothing!
- Finally(!) fix transfer rate timing.
0.0.12 packaged
---------------
- Update INSTALL. Mention the config file can be given on the command line.
- Lower VSFTP_MAX_COMMAND_LINE to 4096 (wu-ftpd uses 512 I think).
- Add RedHat/vsftpd-rh7.spec, kindly provided by Emmanuel Galanos
- Add more RedHat/* spec files etc, kindly provided by Andrew Anderson
- Cleanup: move two process model code to "twoprocess.c".
- Damn! Make the file lock _block_ if it's busy, in sysutil.c.
- Finish implementing one process model - benchmarks to follow
- Don't log success if the download is ABOR'ed during the blocking close().
- Build on systems without PAM (obviously local logins won't work..)
- Beware of FreeBSD accept() bug: [email protected]
- Implemented a customizable ftp banner with "ftpd_banner" config file setting
- Builds on OpenBSD 2.8 - woohoo
- FreeBSD: look for libpam.so* in /usr/lib
- FreeBSD: add #include <sys/param.h> otherwise CMSG_* break.
- Kill privparent.[ch] - merged them into twoprocess.c
- Enable SIGCHLD handler _before_ forking - should nail a race which could lead
to zombies. Inspired by zombie report from Joe Klemmer <[email protected]>.
- Data connection timeout code.
- ftpcmdio.c: Don't cancel the alarm when we get a command. For safety, we
insist that that the only way to "cancel" the alarm is to reset it. This
prevents hangs blocking on write() to the command stream. Of course, data
transfers are long running operations and have their own timeouts.
- Data transfer timeout now kills session.
- Take care that no writes block once we've decided to abandon ship.
- FreeBSD sendfile() support. I wonder if it works!
0.0.13 packaged
---------------
- Split out directory listing code into ls.c
- Change blocking accept() and connect() code to use select() not SIGALRM!
- Remove alarm() timeout junk from file locking in logging.c
- Cater for signals interrupting the blocking file lock
- Whoops: fix data timeout incorrectly going off. Noted and fixed by Joshua
Hill <[email protected]>.
- Implement tunable_pasv_promiscuous to relax PASV IP checks. Useful if you
are playing with secure tunneling of command connection. Idea, patch from
Seth Vidal <[email protected]>.
- Much better line-by-line file reading string buffer functions.
- Use the above better functions for directory messages and config file
reading. This eliminates a probable quadratic algorithm, i.e. it's a speedup.
- Explictly free certain buffers rather than using the static trick. For
example, the config file buffer which is only used once.
- Massive cleanup and refactoring of login code.
- Add ability to specify file containing list of banned e-mail addresses for
anonymous users. Apparently a required feature for big sites trying to avoid
DDoS attacks.
- Add ability to specify file containing list of users to chroot(), request
from helo <[email protected]>, who also persuaded me not to use the homedir
hack in /etc/passwd.
- Add TODO: PASV port range config setting, for firewalled setups. From Rafal
Wojtczuk <[email protected]>.
- Rudimentary support for non-PAM local user authentication, with
encouragement and helpful discussion from D Richard Felker III
- Use MAP_ANON instead of mmap() /dev/zero for anonymous pages. It saves
using a file descriptor. Neither are standard(?) but MAP_ANON seems to work
on a superset of systems compared with mmap() /dev/zero.
- Ability to specify a PASV local port range with pasv_min_port and
pasv_max_port. Request from Rafal Wojtczuk <[email protected]>.
- Non-PAM authentication: check /etc/shells, and support shadow password and
account expiry.
- First cut at a vsftpd.conf man page! (vsftpd.conf.5)
0.0.14 packaged
---------------
- Default to ASCII mode transfers, as per RFC. Bug noted with Macintosh client
by William Day <[email protected]>.
- Implement "ls -a".
- Implement "ls -r".
- Implement "ls -l", i.e. "NLST -L" now works
- Implement "ls -t". Superb - now the oft-used "ls -ltr" works!
- setproctitle() support - FreeBSD only in the first cut.
- setproctitle() on Linux support - what a hack! This crap really needs kernel
support. I'm ashamed I bothered.
- Repair the contributed spec files a bit, based on reports from Oleg Drokin
<[email protected]> and Jakob Lichtenberg <[email protected]>.
- Show remote IP and local username in setproctitle() support.
- Add vsftpd.8 man page, thanks to Daniel Jacobowitz <[email protected]>.
- In sysdeputil.c, check macros LINUX_VERSION_CODE and KERNEL_VERSION are
defined. From James Antill <[email protected]>.
- Workaround a broken firewall that expects a very precise PASV response. We
now match wu-ftpd. Many many thanks to Jakob Lichtenberg <[email protected]> for
his help.
- If tunable_anon_world_readable_only (default), don't list directories unless
they are world readable.
- Use qsort() for directory sorting - eliminates gross quadratic sorting.
Turbo charges directory listings with 1000's of entries.
- Fix big memory leak in str_list_free().
- Simplify + reduce heap usage in strlist.c
- Optimize away lots of excessive heap usage and redundant copying in str.c
- By default, show numeric user/group id's in directory listings. Makes
generating directory listings perhaps 4 times(!) faster, and is noticeable
with e.g. 5000 entries in a directory. n.b. this performance figure is as
measured on a glibc-2.2 system, so glibc would seem to be inefficient.
- Don't use MSG_DONTWAIT - prefer the more portable fcntl()/O_NONBLOCK. Fixes
glibc-2.0 build issues.
- Work around broken Linux-2.0 unix fd passing. Now builds/runs on RH5.2.
- Build fixes for FreeBSD 3.5, with help from Jerry Walsh <[email protected]>.
- Only restrict directory listings to world-readable for _anonymous_ users!
Thanks again Jerry Walsh <[email protected]> for the report.
- Add TUNING
- Special case for security/performance: if we need _no_ privilege, then
force one process model. Security: root dropped totally straight away.
Performance: no messing around forking etc.
- Minor performance tweaks, don't leave big mappings lying around from
config file parsing.
0.0.15 packaged
---------------
- Argh. Fix SuSE 6.0 build issue (time_t used but not defined). Reported by
Peter Stern <[email protected]>.
- Another SuSE 6.0 issue - another damn system lacking CMSG_SPACE etc.
- Cope with any return value from blocking close(2). Previously, we missed
EAGAIN, which some systems might return (not Linux).
- New wizzy synchronous signal framework, to prevent re-entrancy issues. It
presents an interface very similar to the traditional UNIX async interface.
Technically this is a security fix; imagine a SIGURG (user controllable!)
coming in whilst we are deep inside glibc. The SIGURG handler is non-trivial
and may well re-enter and upset glibc. Specific example: the malloc subsystem.
- When handing SIGURG, account the time taken under the data tranfer timeout.
- Install the command timeout handler before we write anything to the remote.
- Cleanup capabilities handling to be taken care of in secutil.c.
- Fix bug: one_process_model mode could lose supplementary groups.
- Add "SIZE" file.
- Make one_process_model work with the anon deny e-mail list.
- Massive cleanups. Start moving static state into a session structure.

include a dirfd() replacement. Noted by William Yodlowsky
<[email protected]> and Mike Batchelor <[email protected]>.
- Fix return of a void function call in a void function. It upsets Sun's
compiler. (gcc is fine with it, I'm not sure if it's against the rules).
Noted by Mike Batchelor <[email protected]>.
- Make it possible to use port ranges starting lower than 5001, from
Matthew Kirkwood <[email protected]>.
- Use a /dev/zero mmap() fallback if we do not find MAP_ANON. This should
fix the build on Solaris 2.6, 2.7 machines. Reported by Mike Batchelor
<[email protected]>. Also noted as one of the problems facing an IRIX build.
- Add MDTM support, so clients like ncftp can set the date on downloaded files.
- Add irix_bogons.h, trying to port to IRIX 6.5, with help from Jan-Frode
Myklebust <[email protected]>.
- Don't reference "struct msghdr.msg_flags", not all systems have it. Clear it
with vsf_sysutil_memclr() instead. Found on IRIX 6.5.11
- Cater for systems lacking getusershell(), e.g. IRIX 6.5.11, by not using it.
- Fix compiler error with header files claiming 2.4 headers but only having
2.2 headers. Reported by Ben Ricker <[email protected]>.
- Kill warning on system without capabilities.
- Add -R option to ls (disabled by default), to cater for broken clients which
assume it is present (e.g. mirror).
- Add "Makefile.sun", from Mike Batchelor <[email protected]>.
- Fix PORT transfer crashes with "one_process_model". Reported by
Andrew Anderson <[email protected]>.
- Cater for HP-UX shared libraries which end in ".sl", from Kevin Vajk
- Add hpux_bogons.h, and make MAP_ANON a synonym for MAP_ANONYMOUS.
- Move send_fd and recv_fd to sysdeputil.c and provide old-style fd passing
code for IRIX and HP-UX.
- Get it going on HP-UX 11.11 and HP-UX 10.20, thanks to Kevin Vajk
<[email protected]>. Minor changes to hpux_bogons.h
- Update vsftpd.conf with "ls_recurse_enable".
- Get it going on IRIX 6.5.11, thanks to Jan-Frode Myklebust
- Fix reporting of filenames in MKD operations (regression since 0.0.15).
- Wow - lots of contributed .spec files. Adopt those from Seth Vidal
- Fix FreeBSD build.
0.9.0 packaged
--------------
- Fix .spec files to include URL, from Seth Vidal <[email protected]>.
- Don't let unprintable characters escape into setproctitle(). Thanks to
Solar Designer for the suggestion.
- Make the PAM service name a tunable, suggestion from Solar Designer.
- Add option to log all FTP protocol (log_ftp_protocol).
- Log logins, successful or failed.
- Refuse to download a file in ASCII mode if REST position != 0. Solar
reminded me by looking in the BUGS file.
- Clearly mark an ASCII download in the FTP response string.
- Argh. Fix broken upload timeout again (goes off erroneously).
- Fix logging of FTP protocol, add logging of pid. Reported by Frank Fiamingo
- Fix bug where logging code bug()'s on the second logged operation, iff
logging is in fact disabled! Reported by Alexander Schreiber
- From Solar: be paranoid about libc implementations of isprint() in sysutil.c
- Careful not to write any unprintable characters into the log.
- fchmod() files that we fchown(), to prevent suid games, etc.
- Cleanups, added comments to some headers.
- Minor speedups to some str.c string handling functions.
- Joe Klemmer <[email protected]> reports zombies again! Nail a couple of
races: make the SIGCHLD handler async, and cater for an interrupted wait(2)
syscall.
- If chroot_local_user=YES then chroot_list_enable becomes a list of users to
NOT chroot(). With input from Lars Hecking <[email protected]>.
0.9.1 packaged

- Fix chown_upload bug in a different way.
- Correct *_umask details in vsftpd.conf.5, from brett <[email protected]>.
- Don't show .files unless "ls -a" was specified, n.b. this differs in
behaviour from wu-ftpd, but not proftpd.
- Implement directory write(2) buffering, for a 33% reduction in CPU used to
send big dirs. Activate the bandwidth limit on directory listings.
- HPUX enhancements: setproctitle and sendfile. Thanks to Kevin Vajk
- We DON'T need to follow symlinks on "ls -R" - phew.
- Add README.solaris. Thanks to Mike Batchelor <[email protected]>.
- Implement passing remote host to PAM (for pam_access etc.), thanks to
Emmanuel Galanos <[email protected]>.
- Fix guest_enable so that this means all non-anonymous users are guest users.
- Add ability to deny selected users before they get the chance to send their
cleartext password!!
- Fix FreeBSD build - use a cast instead of floor() which needs libm.

- Fix REST + STOR combination, investigation inspired by Mike Batchelor
0.9.3 packaged
--------------
- Update xinetd file to reflect /usr/local location. Thanks to Fridtjof
Busse <[email protected]>.
- Make our 150 response code match wu-ftpd - allows broken "ange-ftp" of
emacs to do a percentage complete indicator. Reported by Jonathan Kamens
<[email protected]> via Andrew Anderson <[email protected]>.
- Fix build on S390, ia64 platforms (poor kernel includes). Patch from
- Fix up vsf_findlibs.sh to cater for RedHat7.2 which has libcap. Reported
by Chris Burton <[email protected]>.
- Boast some more in BENCHMARKS.
- Add anon_root and local_root, inspired by Ole Tange <[email protected]>.
- Fix up vsf_findlibs.sh to cater for broken Mandrake, and also consider
the case of missing PAM headers (no pam-devel installed). Thanks to

-------------------------------------
(Note - 1.1.0 also included large file (>2Gb) support).
- Fix port_promiscuous, oops! Thanks to Bjørn-Ove Heimsund
- Fix to support umasks which create executable files. Reported by
"Martin, Andreas" <[email protected]>.
- Make the messages more.. professional :( Thanks to Steven G. Taylor
- Allow anon users to append to files if they can delete files! Suggestion
from Michael Leuchtenburg <[email protected]>.
- Hopefully fix Solaris build (-lresolv)
- Replace atoll() with a homebrew - modern FreeBSD, OpenBSD lack it.
- Different solution for a umask which creates executable files:
file_open_mode.
- First attempt at Tru64 build, working with <[email protected]>.

environment variables. Allows per-IP configurability in standalone mode.
- Fix build without tcp_wrappers.
- Fix Solaris sendfilev() support - interruption via a signal returns EINTR
rather than a partial byte count!
- Add to EXAMPLE/ - PER_IP_CONFIG and INTERNET_SITE_NOINETD
At this point: 1.1.3 package released
-------------------------------------
- Eliminate crypt() not defined warning.
- "grep -q" is not standard to redirect to /dev/null instead.
- Make banned_email_file work second time around.

virtual_use_local_privs=YES.
- Fix sendfile() fallback on FreeBSD, thanks to Adam Stroud
- 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 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

At this point: v1.2.0 released!
===============================
- Apply NetBSD patch to sysdeputil.c to activate a few features. Thanks to
Lubomir Sedlacik <[email protected]>.
- Apply fix for broken clients that terminate commands with \r\r\n. Thanks
to Andrey Chernomyrdin <[email protected]>.
- AIX send_file support, thanks to Tomas Ogren <[email protected]>.
- Fix typos in vsftpd.conf.5, thanks to SEKINE Tatsuo <[email protected]>.
- 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 <[email protected]>.
- 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 <[email protected]>.
- Implement simple {,} support in pattern matcher (nested not handled). Handy
to use with hide_file and deny_file options.
(v1.2.1pre2)
- 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, <[email protected]>.
- Add some FAQ entries.
(v1.2.1pre3)
- 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).
At this point: v1.2.1 released!
===============================
- Fix FreeBSD 5.1/5.2 issue with time_t being long long on that platform.
Thanks to Matthias Andree <[email protected]>.
- Tweak vsftpd.conf.5 to avoid automated mails from ESR ;-)
- Remove vsftpd spec files, they are old and buggy.
- 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). Many thanks to Olivier Baudron
<[email protected]> for an excellent report.
(v1.2.2pre1)
- Fix build with modern glibc-2.3 and no libcap on Linux.
- Fix 64-bit file support on Solaris.
(v1.2.2pre2)
- 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 INSTALL to refer to more modern platforms.
At this point: v1.2.2 released! (need to get the listener fix out)
==================================================================
- 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 <[email protected]> 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 <[email protected]>.
- If trans_chunk_size is between 1 and 4096, use 4096 rather than ignoring
totally. Thanks to Brad <[email protected]>.
- 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 <[email protected]>.
- 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 <[email protected]>.
- 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 <[email protected]>.
- 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
<[email protected]> 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 <[email protected]> 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 <[email protected]> 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 <[email protected]>, Radek Vokal <[email protected]> and
Andreas Kupfer <[email protected]>.
- 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 <[email protected]> (using CuteFTP and BackupEdge) and
Christian DELAIR <[email protected]> (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 <[email protected]>.
- Fix MDTM on non-existant files. Reported by Ken A <[email protected]>.
- {} regex fix so that {*} correctly matches everything. Reported by
Tom Van de Wiele <[email protected]>.
- Add "mdtm_write" option to disable MDTM being able to set file timestamps.
- Fix HPUX build, thanks to Kevin Vajk <[email protected]>.
- Add optional file locking support via lock_upload_files (default on).
- Apply LDFLAGS patch from Mads Martin Joergensen <[email protected]>.
- 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 <[email protected]> and
Mads Martin Joergensen <[email protected]>.
At this point: v2.0.4 released!
===============================
- Apply fix for O_NONBLOCK vs. XFS DMAPI filesystem. Thanks to Sudha Srinivasan
- 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 <[email protected]>. Allows MS Explorer to get the transfer mode
correct.
- pam_pwdb.so -> pam_unix.so in example PAM file. Thanks to
Rhodes, Colin <[email protected]>.
- 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.
At this point: v2.0.5 released!
===============================
- 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
- Allow a (fake) reauth as the same user as the logged in user. Should resolve
.NET related report from Sabo Jim <[email protected]>.
- Tweak from Lucian Adrian Grijincu <[email protected]> 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
- Don't log FireFox's attempts to RETR directories! Reported by
Nixdorf, Tim <[email protected]>.
- Fix STOU sending the same 150 status line twice - oops! Reported by
- Fix xferlog format for virtual (guest) users, reported by Andy Fletcher
- Fix bug with empty user list file and userlist_deny=NO. Reported by
Marcin Zawadzki/GlobalVanet.com <[email protected]>.
- Pretend we have proper UTF8 support and respond positively to OPTS UTF8 ON.
Thanks Stanislav Maslovski <[email protected]>.
- 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 <[email protected]>.
- Do a retry getting the active ftp socket in vsf_privop_get_ftp_port_sock();
should help buggy Solaris systems. Reported by Michael Masterson
- 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.
At this point: v2.0.6 released!
===============================
- Fix finding libcap for the link on Slackware systems, thanks to Roman
Kravchenko <[email protected]>.
- Fix build on Solaris 2.8 due to non-standard C, thanks to IIDA Yosiaki
- Fix man page typo, thanks Matt Selsky <[email protected]>.
- Bring the PASV listen() into the bind() retry loop to resolve a race under
extreme load. Thanks to Curtis Taylor <[email protected]>.
- 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.
At this point: v2.0.7 released!
===============================
- Remove .postlogin.c.swp (thanks Kaibin Li <[email protected]>)!
- 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 protected]>.
