This file contains all major changes made during the development of bftpd.
The uppermost change is the newest one.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 2.2
- Bftpd does not exit when an incorrect password is given.
The server does drop connections in cases where logins are
specifically denied, full server or if an error appears in
the config file.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 2.1.2
- Added option to not show files in a dir list
if the file is not readable. Thanks to Eric
Woltermann for sending in this patch.
By default non-readable files are not listed.
See the SHOW_NONREADABLE_FILES config option.
- Make the replace() function safer with
range checking to avoid buffer over-flow.
- Fixed calls to replace() function.
- Most string buffers now have a set size of
MAX_STRING_LENGTH, rather than some arbitraty size.
- Applied patch to allow user specific data to
be subsituted into the user MOTD file path.
The symbols %u and %h and be used in place of the
user's username and home directory in the MOTD_USER
config option.
Thanks to Eric Woltermann for submitting this patch.
- Bftpd now prompts for a password, even on anonymous
accounts to help increase compatiblity with some
web browsers.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 2.1.1
- Fixed directory creation so that the proper
umask is used. thanks to Thiemo for pointing
out this problem.
- Fixed buffer under-size error in options.c
Thanks to Athan for reporting this bug.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 2.1
- By default, the SITE command is now disabled
in the bftpd.conf file. This is to prevent
security holes and DoS attacks via "site md5 <filename>"
Jesse Smith <jessefrgsmith@yahoo.ca> -> 2.0.3
- Added md5 support for amd64 machines.
- If no arch is defined for md5, assume little endian.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 2.0.2
- Transfer buffer size now defaults to staying the
same (max) size for all transfers. To get a variable
buffer size, change the config option CHANGE_BUFSIZE
to "yes".
- Added config file option SHOW_HIDDEN_FILES. When this
option is set to "yes", bftpd shows hidden files in directory
listings. By default this is set to "no".
Jesse Smith <jessefrgsmith@yahoo.ca> -> 2.0.1
- Avoid possible segfault in replace() function
in mystring.c
- Avoid memory error in main.c using strdup()
- Avoid segfault in options.c the create_options()
- Added ability to use the SITE command to provide md5
checksums of files. (usage: site md5 filename)
Very many thanks to Ulrich Drepper and Gray Watson for
the md5 library!
- Changed ratio calculations to use double type to
allow for larger files and data transfers.
- Added HELP option to the SITE command.
(usage: site help)
- Added config file variable CHANGE_BUFSIZE. This
determines whether the transfer buffer changes size.
It defaults to "yes".
- Removed extra fileno() calles in file receives.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 2.0
- Avoid memory error in options.c
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.9.3
- Avoid segfaults in options.c and cwd.c
- Added memory checks in options.c
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.9.2
- Avoid segfaults in options.c and dirlist.c
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.9.1
- Avoid segfaults in options.c and main.c
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.9
- Added limits.h entry to main.c and options.c
for compatibility with FreeBSD.
(All problems with bftpd on FreeBSD were found and
corrected by Beech of the FreeBSD team.)
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.8.4
- When printing file sizes for files larger than 4GB
the file size is now displayed correctly.
- When a FTP client drops a connection without sending
an ABORT (ABOR) signal, Bftpd will detect the dropped
connection and log it. This prevents stale connections
preventing new users from connecting.
(Bug found and fixed by: Thorsten)
- Added limits.h and signal.h to list of headers used
in commands.c, for compatibility with BSD.
- Changed sighandler_t in "run_script()" to sig_t
for compatibility between Linux and BSD.
- Added OpenPAM patch from FreeBSD (login.c)
- Added limits.h include to login.c file for
compatibility with BSD.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.8.3
- If Bftpd is unable to create bftpdutmp file, an error
should now be written to the log file.
- Directory output corrected for when large files (> 2GB)
are listed.
- Documentation for xinetd config updated.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.8.2
- Changed bftpd's direcotry name to plain "bftpd"
rather than "bftpd-version". This will, hopefully, make
it easier to run scripts which build/run bftpd.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.8.1
- Avoid segfault in getoption() (options.c)
Credit to Mats Erik Andersson for finding this bug.
- Fixed potential memory leaks in commands.c
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.7.2
- Fixed serious bug which would cause bftpd to crash
while sending a file. Double-free error.
(Credit to Davide Pozza for reporting these bugs below.)
- Prevent buffer over-flow in parsecmd() when
forming confstr variable.
- Check return values of strtoul() to make sure they
do not over-flow an int.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.7.1
(Credit to Davide Pozza for reporting these bugs.)
- Avoid memory over-flow in bftpd_login (login.c)
with the str[] variable. Made size 512 + 1.
- Avoid buffer over-flow in str[] variable in
main().
- Prevent buffer over-flow in check_file_password()
when performing fscanf().
- In check_file_password() made calloc() allocate
larger buffer to prevent over-flow.
- Performed range checking on the number of users on
the system to make sure they don't over-flow a 32-bit int.
- Make sure malloc calls in commands.c do not allocate
too much or too little memory.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.6.6
- Perform memory allocation check in bftpd_cwd_mappath()
- Changed a strcmp() to strcasecmp() in command_retr function.
- Performed free(mapped) at end of command_retr.
- Performed memory checks and clean-up in various functions.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.6.5
- The when using the FILE_AUTH option, the text
password file can contain anonymous users. That is,
users who do not require passwords. THIS IS DANGEROUS
ON MOST SYSTEMS. A entry with the password field set to
a * (star) does not require a password. See the
config file option FILE_AUTH for more information.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.6.4
- Allow ANONYMOUS_USER config file option to be used with
the FILE_AUTH option. This basically allows anyone
to login to the system without a password if both
options are used!
- When a chroot fails during login the server will
no longer tell the client which directory it was trying
to chroot to.
- When the config.h file contains a definition for
NO_GETPWNAM then the getpwnam() function is not used.
Also, this forces the use of the FILE_AUTH option. If
NO_GETPWNAM is defined and FILE_AUTH is not used, all
connections are dropped.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.6.3
- Introduced option to over-ride the local/LAN
IP address assigned to the host computer. This
option takes a 4-number IP address in the format
of "127.0.3.101". See OVERRIDE_IP in bftpd.conf for
more information.
- Removed description-pak file from source tree.
- The options PRE_WRITE_SCRIPT and POST_WRITE_SCRIPT
have been added to the bftpd.conf file. These options
let you run scripts before and after any command writes
to the file system. Handy if you want to re-mount.
Please see the bftpd.conf file for details.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.6.2
- When using FILE_AUTH to login, check
DO_CHROOT option before performing
a chroot().
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.6.1
- Removed code which uses sendfile().
The sendfile code appears to cause a
conflict on some systems when used
with 64-bit file size variables.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.6
- Released bftpd without code changes, but
with updated Polish documentation.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.5
- Added Polish documentation to website.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.4.1
- Added ability to use a plain text file
for authentication. See config file option
FILE_AUTH for details.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.4
- Fixed default configuration.
- Fixed compile warnings for vanilla config.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.3.2
- Fixed Makefile to erase config.cache file during
"make clean"
- Added ability to uncompress files on the fly
during downloads. Any file with the extension
".gz" can be decompressed during transfer to
the client with the use of the GZ_DOWNLOAD
in the config file. This option requires bftpd
be configured (pre-compile time) with the flag
--enable-libz.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.3.1
- Changed ratio values to unsigned long
variables to support large files.
- Editted Makefile to allow bftpd to handle large
files (2GB+).
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.2.2
- Added ability to upload files and
compress them into .gz files on the fly.
See bftpd.conf file for the option.
This option requires --enable-libz be
used when running the configure script.
- Cleaned up code to avoid compiler warnings
from gcc 4.0.2.
Files changed: main.c commands.c
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.2.1
- When the config file is re-read, global
are changed only.
Files changes: options.c options.h
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.2
- Made re-reable options be able to hold larger
values. Up to 256 bytes/characters long.
- Replaced old rpm spec file with one from
Joe, which will be used from now on for
rpm builds.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.1.3
- When a child/client dies, the
parent process will now attempt to
remove the client's log entry
from the bftpdutmp file. This
should prevent stale entries.
- Changed some default values to
constants in options.h
- Fixed typo(s) in bftpd.conf
- Set delete/over-write for global
users to be disabled by default
in bftpd.conf.
- Added the XFER_DELAY option to
the bftpd.conf file. This allows
the admin to set a time delay
between data transfer bursts.
This aid in bandwidth throttling.
Please see bftpd.conf for more
details on this feature.
- Added more re-read options
when catching signal SIGHUP.
The re-readable options are now:
HELLO_STRING, QUIT_MSG, XFERBUFSIZE,
DATA_TIMEOUT, CONTROL_TIMEOUT,
USERLIMIT_GLOBAL, USERLIMIT_SINGLEUSER,
USERLIMIT_HOST, DENY_LOGIN and XFER_DELAY.
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.1.2
- Program now catches signal SIGHUP.
- When bftpd catches the SIGHUP (hang up)
it re-reads the config file. It looks
for some config values, but not all.
At this time, the values which are
re-read are:
HELLO_STRING, QUIT_MSG and XFERBUFSIZE
Jesse Smith <jessefrgsmith@yahoo.ca> -> 1.1.1
- Added rpm spec file to redhat directory.
- Changed numberic string length (512) to a defined
string length (MAXCMD). Makes code more
compatible with main.c and uses less stack
memory. File changed: commands.c
- When receiving files, the transfer buffer
(XFER_BUFSIZE) is divided by the number of
connected clients. This should prevent bandwidth
being sucked back by multiple connections.
- Minor fixes, checking for malloc errors,
freeing memory and closing sockets.
File changed: commands.c
- When sending files, the transfer buffer
(XFER_BUFSIZE) is divided by the number
of connected clients. This should prevent
bandwidth being taken over by multiple connections.
- Changed Makefile so bftpd.8 gets installed as
a manual page in the proper location.
Also updated rpm spec file to include man page.
Jesse Smith <slicer69@hotmail.com> -> 1.1.0
- Changed some bftpdutmp_log(0) lines to
calls to bftpdutmp_end(). This should be safer.
- Made sure that clients cannot write or append
to files if the "delete" command is disabled. I
think if they cannot delete the file they shouldn't
be allowed to truncate it to zero bytes either.
- Added reason for login failure to log file.
- Removed logging of getting user count from
temp file. Just seems to be taking up space.
Jesse Smith <slicer69@hotmail.com> -> 1.0.24-2
- Added ability to block multiple connections from the
same IP address. This will keep download managers and
Internet Explorer from taking up multiple connections.
See the new option USERLIMIT_HOST in bftpd.conf.
- Made sure that bftpd logs out stale control connections
via added calls to bftpdutmp_log(0).
- Added alarm() calls before trying to read from
the control socket. We shouldn't assume we are going to
get anything.
Jesse Smith <slicer69@hotmail.com> -> 1.0.24-1
- Fixed bug with NLIST command. The bftpd server should not be
sending leading path in front of filename when using NLIST.
File(s) affected: dirlist.c
- Added the MGET command. Allows client to receive multiple files
with one command.
File(s) affected: commands.c
- Added the MPUT command. Allows client to send multiple files
to the server with one command.
File(s) affected: commands.c
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.24
- The PATH_BFTPDUTMP configuration option was added (idea by Szabo Peter
<pts@math.bme.hu>).
- Whenever a data connection is established, the reply message now
contains the transfer mode (idea by Szabo Peter).
- The -D, -h and -n command line options have been added (idea by Szabo
Peter). Some code was changed to support operation without a configuration
file.
- ATTENTION! The option LOGFILE has changed. See sample config file.
- In daemon mode, bftpd closes its sockets correctly now (important if you
have a lot of connections), problem discovered by Olivier Kaloudoff.
- Fixed a bug that prevented Mozilla from getting directory lists (found
by Marc Pauls).
- Daniel Mack fixed a memory leak in his code.
- The configuration parser handles comments better now.
- The USERLIMIT_GLOBAL configuration option has been added.

- The ALLOW_FXP configuration option has been added.
- The DATA_TIMEOUT configuration option has been added.
- The PASSIVE_PORTS configuration option has been added.
- A control timeout bug has been fixed.
- Configuration options are now written like name="value", allowing
comments after the option. Directories are written like
directory "/foo/bar" {. Please update your config files!
- bftpdutmp logging has been implemented as well as some administration
functions using it. Read the updated documentation for details on how
to use them.
- You needn't link gzip statically to bftpd any more if you want on-the-fly
compression, but you can dynamically link against zlib instead now.
The pax sources are still needed for tar on-the-fly.
- A directory listing bug reported by Hendrik Harms
<hendrik.harms@bigfoot.de> has been fixed.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.21
- The XFER_BUFSIZE configuration option has been added, allowing tweaking
of data throughput. If you and your clients are on a very fast network
(fast meaning 100 Mbit/s or more), you should set this to 64000 or
something like that.
- The APPE command has been implemented.
- The ALLO command has been implemented as an alias to NOOP.
- The INITAL_CHROOT configuration option has been added. See the new
example config file for details.

- The EPSV and EPRT functions have been implemented, making IPv6 support
possible somewhere in the future.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.19
- The NLST function has been made usable again. There has been an
unnoticed bug in it since the globbing function has been implemented.
- The XCWD, XCUP, XMKD, XRMD and XPWD functions have been implemented
as aliases to CWD, CDUP, MKD, RMD and PWD.
- The documentation is now in the SGML format, making it more extensible,
hopefully.
- The DATAPORT20 configuration option has been added. If set to yes,
the server will open data connections from port 20, which should make
firewall users happier.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.18
- The configuration file has been restructured. See README for details.
- The PORT configuration option has been added, allowing you to change
the port number the daemon should listen on (only for daemon mode).
- A workaround for the /*/../* vulnerability mentioned on Bugtraq has
been added, although it's not the right thing to do, really.
- Compatibility to Solaris 8 has been improved. Josh Woodcock
<josh@hamparts.com> and Michael Smirnov <smb@mh.vstu.edu.ru> gave
some hints.
- The CONTROL_TIMEOUT configuration option has been added. You can now
say after how many seconds of idle time users should be kicked.
- Hashes (#) in /etc/passwd and /etc/group are now supported as comments.
This improves FreeBSD compatibility, I'm not sure about other systems.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.17
- A globbing bug was fixed, making Midnight Commander able to connect
to bftpd.
- A bug which appeared when doing LIST if a group line in /etc/group
had more than 256 characters was fixed.
- /etc/shells and /etc/ftpusers authentication were implemented by
Christophe Bailleux.
- You can now indent your configuration options with tabulators.
- A small problem with the ip_conntrack_ftp kernel module has been fixed,
which was the fault of ip_conntrack_ftp. It was found by Erik Hensema
<erik@hensema.xs4all.nl>.
- ASCII transfer mode has been implemented.
- You can now prevent a user from executing specific commands by using
the ALLOWCOMMAND_XXXX=no option.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.16
- .tar and .gz on-the-fly support has been implemented. Look in the
README file if you want to do that.
- Supplementary group IDs are now initialized correctly.
- PORT commands now check if the supplied IP address really belongs
to the client, so that an attacker can't make the server connect
to a machine in its LAN.
- A bug making the wtmp logging system unusable under BSD systems was
fixed.
- A bug making the server crash when logging in a non-existent user
with ANONYMOUS_USER enabled was fixed.
- A patch supplied by Christophe Bailleux was applied, changing the
following:
- Spaces after a command in each command string are removed.
- The HELP command was implemented.
- CWD to ~ now works.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.15
- You can override the default path to the config file with the command
line parameter '-c'.
- wtmp logging was implemented, so that bftpd logins show up in
commands like 'last'.
- You can have bftpd bind to only one interface, for example, if you
want to run an FTP proxy server on the same port on another network
interface.
- The LIST and NLST commands now support globbing.
- A security problem in the syslog code was fixed.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.14
- A lot of bugs found by Christophe Bailleux <cb@grolier.fr> have been
fixed, as always.
- bftpd can now cope with special characters, such as umlauts.
- SITE commands are now disabled by default.
- A bug preventing resolution of GIDs on some systems has been fixed.
- Debian packages are now built for every new version.
- You can now specify if any password should fit for a particular user,
so that you don't have to set a user's password to nothing
(security).
- You can now turn off chroot() for particular users.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.13
- David L. Nicol <david@kasey.umkc.edu> tested bftpd on Tru64.
He also improved the character filtering routine.
- Some RFC incompliance was fixed, improving compatibility with
FTPExplorer and LeechFTP.
- The SIZE command was implemented.
- A bug making the server segfault when being killed was fixed.
- A buffer overflow bug found by asynchro <asynchro@pkcrew.org>,
Jonathan Heusser <jonathanheusser@gyml.unibas.ch> and Christophe
Bailleux <cb@grolier.fr> was fixed.
- The SITE CHMOD and SITE CHOWN commands were implemented. You can turn
them off in the config file.
- A lot of useful changes proposed by Heiko Rother <rother@cmsnet.de>
were made:
- Standalone mode, independent from inetd
- Better support for symbolic links
- Display of user/group name instead of UID/GID
- Ability to set the umask
- Ability to log into syslog
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.12
- SmartFTP support was improved (parameters to LIST beginning with -
are discarded).
- A buffer overflow bug found by Christophe Bailleux <cb@grolier.fr>
was fixed.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.11
- PAM support was implemented. Specify --enable-pam while starting
configure to use it.
- You can now specify users who should be unable to log in.
Max-Wilhelm Bruker <brukie@gmx.net> -> 1.0.10
- Applied a big patch from Daniel Mack that makes some things better,
for example virtual host support, a FreeBSD correction for the
directory listings, etc.
