3.0.4_vs_3.0.5.

1 0.0.1 initial versioned tarball released 2 ---------------------------------------- 3 4 - Added "-ldl" to LIBS to get linking to work on RedHat6.1 5 - Add RedHat6.1 on list of tested platforms :) 6 7 0.0.2 packaged 8 -------------- 9 10 - Emit version in greeting string 11 - In PORT command, reject numbers <0 or >255. Problem noted by Solar Designer, 12 <solar@openwall.com> 13 - Allow an option AND a path for LIST/NLST, e.g. "LIST -al /pub". Reported by 14 Bill Nottingham <notting@redhat.com>, using ncftp. Further noted by Colin 15 Hogben <chah@jet.uk> using emacs and James Antill <james@and.org>. 16 - Don't prepend directory path for LIST (but still so for NLST). Noted by 17 Colin Hogben <chah@jet.uk> and Ingo Luetkebohle <ingo@blank.pages.de> 18 - Fix problem listing non-existant or unreadable directories - just return 19 a blank listing rather than an error. Problem noted by Martin Sillence 20 <martin.sillence@prnewswire.co.uk>, using squid. 21 - Fix KDE's downloads (via KFM), it was using the "SIZE" command which I had 22 not implemented. Reported by Simon Dales <simonD@nuffield.co.uk> and Jo Dillon 23 <jo@trolltech.com>. Apparently implementing SIZE also fixed lftp's download 24 time estimator, reported by Ingo Luetkebohle <ingo@blank.pages.de> 25 - Remove abornal_exit() from utility.c 26 - Fix so we don't write "500 OOPS: child died" upon QUIT. Reported by Solar 27 Designer, <solar@openwall.com> and Tim Bagot <tsb@earth.li> 28 29 0.0.3 packaged 30 -------------- 31 32 - Oops: fix so we don't emit a status 150 mark unless we actually got a 33 connection from the client (stops some clients hanging trying to list an 34 inaccessible directory) 35 36 0.0.4 packaged 37 -------------- 38 39 - In verbose directory listing, report symlink targets. Use the traditional 40 syntax of: "link_name -> target_path" 41 - Damn netscape! The comma in the response text to PASV confused it, so it 42 had to be removed. Discovered with tcpdump! 43 - Don't require clients to redo PORT or PASV if a RETR or STOR fails due 44 to inability to open/create file. Fixes Netscape symlink navigation problem. 45 - Fix for listing absolute paths with only one /, e.g. "ls /.message" was 46 failing 47 48 0.0.5 packaged 49 -------------- 50 51 - Remove README.ftpproto 52 - Add SECURITY/OVERVIEW 53 - Add SECURITY/DESIGN 54 - Note that as a security tweak, we should lose more privs if we're configured 55 for anonymous only logins (TODO) 56 - Add SECURITY/IMPLEMENTATION, SECURITY/TRUST, but nothing in them yet. 57 - Convert str.c to vsf_sysutil_*. This leaves the following to do: 58 checkauth.c, main.c, postprivparent.c, privparent.c, privsock.c, utility.c 59 - Convert privparent.c to vsf_sysutil_*. 60 - Create BUGS and move existing listed bugs from TODO into this new file 61 - Add parseconf.h, parseconf.c to handle parsing of a config file (work in 62 progress) 63 - Fix change_full_credentials() in utility.c, to always chdir() even if we 64 are not going to do a chroot() 65 - Rename get_random_byte() to vsf_sysutil_get_random_byte(), and move from 66 utility.c to sysutil.c 67 - Create new file secutil.c, move change_full_credentials() to it and rename 68 - Convert utility.c to vsf_sysutil_*. 69 - handle_local_login(): don't look up username; common_do_login() does it 70 - implement different tunable umask() values for local/anonymous users 71 - implement SITE UMASK 72 - implement SITE CHMOD 73 - whoops! allow non-anonymous users to overwrite files with STOR 74 75 0.0.6 packaged 76 -------------- 77 78 - SECURITY: when in anonymous-only mode, reject usernames that aren't the 79 anonymous usernames. This is hoping some FTP clients will be stopped from 80 sending a cleartext password. Idea from Gerald Teschl <gt@esi.ac.at>. 81 - Decided to put "telnet strings" on the back burner :) 82 - Sprinkling of static in main.c 83 - Complete parseconf.c config file parsing and plug it into main.c 84 - Convert main.c to vsf_sysutil_*. This leaves 85 checkauth.c, postprivparent.c and privsock.c 86 - Now we have runtime config, make compiled in defaults extra paranoid 87 - Implement "tunable_anon_world_readable_only" to only serve publicly 88 readable files anonymously 89 - Add sample "vsftpd.conf" 90 - Eww - missing "return" in parseconf.c 91 - Move ASCII mode transfers out of critical section in TODO 92 - parseconf.c: if an integer starts with "0", treat it as octal 93 - Ban "SITE CHMOD" if !tunable_write_enable 94 - Wrote SECURITY/TRUST 95 - Wrote SECURITY/IMPLEMENTATION, probably more to come 96 - Update INSTALL 97 - Add "tunable_nopriv_user" 98 - Update parseconf.c with the two latest new config variables 99 - Add sysdeputil.h, sysdeputil.c for system specific facilities, i.e. 100 capabilites, authentication. 101 - Lose checkauth.c,h - they moved into sysdeputil.c,h 102 - Lose config.h - it moved into sysdeputil.c 103 - Convert postprivparent.c to vsf_sysutil_* (leaves privsock.c) 104 - Convert privsock.c to vsf_sysutil_*. All done, yay!! :) 105 - D'oh! Missing "!" in postlogin.c refused to server publicly readable files:) 106 - Fix chown() of uploaded files (broken initialization order in main()) 107 - Add SPEED, and fill it with wild speculation 108 - Rename distribution directory "vsftpd-x.x.x" (note the added "d") 109 110 0.0.7 packaged 111 -------------- 112 113 - Build with -O2 114 - Fix "uninitialized" warnings -O2 exposed - the one in capabilities setup 115 could be nasty! 116 - Nail warning in vsf_sysutil_sendfile(). We're now "-Wall warning free" 117 - Build with -Werror to signal intent to _stay_ warning free 118 - A few int -> long in the area of file sizes and offsets 119 - Remove comma's at end of enum lists (-pedantic caught it) 120 - Impact from fixing warnings caused by -pedantic 121 - Date format %e -> %d in date display, %e isn't everywhere 122 - Paranoia in vsf_sysutil_malloc() 123 - Clean up interface to substring searching in str.c 124 - Cleanups in str.c 125 - Squash most "unsigned<->signed" conversions exposed by -Wconversion 126 - Lose "-g" to CFLAGS; after all we're bug-free now ;-) 127 - Add "AUDIT" 128 - Fix up a bunch of potential 64-bit issues (maybe >2Gb files will work on 129 64-bit platforms now, no way to test) 130 - Implement PR_SET_KEEPCAPS support for 2.2.18+ and 2.4.0+ kernels 131 - In sysdeputil.c, change NULL -> 0 to help Solaris build problem 132 - Repair vsf_sysutil_sendfile() and the caller 133 - Logging: log the username 134 - Logging: don't log "//" as start of filenames under certain conditions 135 - Logging: log the date. Logging is almost useful now! 136 - Logging: log MKD commands too; they are used in anon ftp a fair bit 137 - Take the trouble to look into partial reads/writes. Looks like we are safe. 138 - vsf_sysutil_read and vsf_sysutil_write now hide EINTR and retry 139 - Replace some vsf_sysutil_{read,write} usage with 140 vsf_sysutil_{read,write)_loop which handles partial reads and writes 141 - Implement a sendfile() replacement for systems which lack it 142 - Implement runtime checking for system specific Linux stuff, i.e. 143 prctl(PR_SET_KEEPCAPS). This is inspired by RedHat7.0 headers claiming to 144 be a 2.4.0 kernel, but actually you are running on 2.2.x! :-( 145 - Strip the build executable at link time 146 147 0.0.8 packaged 148 -------------- 149 150 - A few incorrect sizeof()'s in postlogin.c, thanks to Antonomasia 151 <ant@notatla.demon.co.uk> for noting these. 152 - Decide that ASCII support isn't too important for now (waiting for users to 153 demand it). Also decide that ABOR is a must :( Thanks to Zach Brown 154 <zab@zabbo.net> for the discussion. 155 - More TODO items thanks to Stephen White <swhite@ox.compsoc.net> - 2.0.x 156 issues. 157 - Provide a definition for SHUT_RDWR in sysutil.c, not all systems have that 158 definition yet. Thanks Stephen White <swhite@ox.compsoc.net>. 159 - Tidy privparent.c 160 - Decide ASCII _is_ quite important, thanks Solar ;-) 161 - Bit of extra paranoia in sysutil.c: don't call mem*() if size == 0 162 - Tidy str.c 163 - Command line: if vsftpd has an argument, it is a path to a config file. 164 - Set TCP_NODELAY on command stream 165 - Don't lseek() for RETR in common case with REST set to 0 166 - Correct error code for transfer after succesful connection (425 -> 426) 167 - ABOR support. Bah. 168 - APPE support (why not, it was trivial). Putting off ASCII support ;-) 169 - Add ASCII transfer support. Bah. 170 - Tidy up sysutil.c, fix breakage in read_loop and write_loop. 171 172 0.0.9 packaged 173 -------------- 174 175 - Remove ".message" from distribution. Thanks Mitchell Blank Jr 176 <mitch@sfgoth.com> 177 - Note where I can get some load testing software, thanks to Dan Kegel 178 <dank@alumni.caltech.edu>. I'll do that soon because I hope to waste wu-ftpd. 179 - Fix an Alpha build warning and check return value from final pam_end(). 180 Reported by Solar Designer <solar@openwall.com>. 181 - Add xinetd.d/vsftpd, from Kurt Seifried <listuser@seifried.org>. 182 - Integrate comments/fixes into SECURITY documentation, thanks to Antonomasia 183 <ant@notatla.demon.co.uk> 184 - SECURITY: default tunable_chroot_local_user to 0, because it is dangerous to 185 give users write access to the filesystem root (think of opening trusted 186 files relative to the root). Thanks again Solar Designer 187 <solar@openwall.com>. 188 - Add "make install" target. Currently it is minimal! 189 - Clearer error message if vsftpd is started manually. Suggestion from 190 Tom <tom@lemuria.org>. 191 - Report futuristic or old (>6 months) dates in a different format, showing 192 the year like /bin/ls does. 193 - Add KERNEL-2.4.0-WARNING. Whoo-hoo. Why do all my non-trivial programs seem 194 to trigger kernel bugs? 195 - SECURITY: refuse to allow anonymous logins if some bonehead has configured 196 the anonymous ftp user with write access to the ftp root. 197 - Fix ASCII downloads so that \n UNCONDITIONALLY maps to \r\n. This behaviour 198 is now consistent with wu-ftpd and results in simpler code. 199 - Fix ASCII uploads to not to fail to strip some \r characters. Noted by 200 Mitchell Blank Jr <mitch@sfgoth.com>. 201 - Add TODO items: log transfer rate and anonymous password. Andrew Anderson 202 <andrew@redhat.com>. 203 204 0.0.10 packaged 205 --------------- 206 207 - Remove errant #include <sys/sendfile.h> from sysutil.c. Noted by Jan-Frode 208 Myklebust <janfrode@parallab.uib.no> 209 - Use gettimeofday(2) not time(2), for better resolution. 210 - Add transfer rate to the log 211 - Add <limits.h> to sysutil.c, spotted by Kevin Vajk <kvajk@cup.hp.com>. 212 - Spell "LICENSE" correctly: Kevin Vajk <kvajk@cup.hp.com>. 213 - Use fcntl() for locking instead of flock() because it is much more standard. 214 flock() usage noted by Kevin Vajk <kvajk@cup.hp.com>. 215 - Use more portable IPPROTO_* instead of SOL_* (IPPROTO_IP, IPPROTO_TCP). 216 Thanks to Neil Blakey-Milner <nbm@mithrandr.moria.org> porting to FreeBSD. 217 - Start of Solaris port, thanks to Kurt Seifried <seifried@securityportal.com> 218 for access to a Solaris 8 box. 219 - Portability fix: include <netinet/in_systm.h> before <netinet/ip.h>. 220 - Port to Solaris 8: new directory port. New file porting_junk.h. New file 221 solaris_bogons.h 222 - Add vsf_findlibs.sh to cater for different platform link requirements. Now 223 builds on Solaris and Linux with "make". 224 - struct sockaddr casts to kill Solaris warnings. 225 - sysdeputil.c: remove unused variable warnings. 226 - sysutil.c: use _exit() instead of exit() to avoid libc doing stuff on exit. 227 Fixes segfault reported by Joshua Hill <josh@untruth.org>. 228 - Add BENCHMARKS. Many thanks to Andrew Anderson <andrew@redhat.com>. 229 - Fix disconnect/crash if SIGURG received whilst blocking on command stream. 230 - Update INSTALL with more platforms. 231 232 0.0.11 packaged 233 --------------- 234 235 - Brag about performance in README. And why not. 236 - Better bail-out message if the "ftp" anonymous user isn't found 237 - Better bail-out message if the secure chroot directory isn't found 238 - Introduce tunable_one_process_model and start work on it 239 - Fix rare segfault on exit - race leading to infinite stack recursion 240 - Don't bail out if we didn't get an argv[0]. Who cares? Noted by Kurt Seifried 241 <seifried@securityportal.com>. 242 - Change logged date format to include the year. 243 - Add option to log in standard (wu-ftpd like) "xferlog" format. 244 - Cater for sendfile() returning EINTR in sysdeputil.c 245 - Use SO_LINGER on data sockets, to get accurate transfer rates! 246 - Cater for an interrupted blocking close() 247 - Tuning: eliminate 3 mprotect(), 1 munmap() and 1 mmap() system call per 248 command read. 249 - Prevent infinite loops calling sendfile(). Two bugs - we needed to check 250 the sendfile() return for 0 (doh!!) and also, we sometimes did lseek() on 251 a file, to beyond its end. Thanks to Daniel Veillard <Daniel.Veillard@imag.fr> 252 for reporting. 253 - Tuning: cache fd's for /etc/passwd and /etc/group to avoid syscalls. 254 - Tuning: "assist" the get*uid(), get*nam() calls to not make lots of useless 255 syscalls, if /etc/group and /etc/passwd are missing. Thanks to Daniel Veillard 256 <Daniel.Veillard@imag.fr> for reporting. 257 - Use SO_LINGER timeout of 5 mins; INT_MAX seemed to do nothing! 258 - Finally(!) fix transfer rate timing. 259 260 0.0.12 packaged 261 --------------- 262 263 - Update INSTALL. Mention the config file can be given on the command line. 264 - Lower VSFTP_MAX_COMMAND_LINE to 4096 (wu-ftpd uses 512 I think). 265 - Add RedHat/vsftpd-rh7.spec, kindly provided by Emmanuel Galanos 266 <egalanos@anchor.net.au>. 267 - Add more RedHat/* spec files etc, kindly provided by Andrew Anderson 268 <andrew@redhat.com>. 269 - Cleanup: move two process model code to "twoprocess.c". 270 - Damn! Make the file lock _block_ if it's busy, in sysutil.c. 271 - Finish implementing one process model - benchmarks to follow 272 - Don't log success if the download is ABOR'ed during the blocking close(). 273 - Build on systems without PAM (obviously local logins won't work..) 274 - Beware of FreeBSD accept() bug: ai32@drexel.edu 275 - Implemented a customizable ftp banner with "ftpd_banner" config file setting 276 - Builds on OpenBSD 2.8 - woohoo 277 - FreeBSD: look for libpam.so* in /usr/lib 278 - FreeBSD: add #include <sys/param.h> otherwise CMSG_* break. 279 - Kill privparent.[ch] - merged them into twoprocess.c 280 - Enable SIGCHLD handler _before_ forking - should nail a race which could lead 281 to zombies. Inspired by zombie report from Joe Klemmer <klemmerj@webtrek.com>. 282 - Data connection timeout code. 283 - ftpcmdio.c: Don't cancel the alarm when we get a command. For safety, we 284 insist that that the only way to "cancel" the alarm is to reset it. This 285 prevents hangs blocking on write() to the command stream. Of course, data 286 transfers are long running operations and have their own timeouts. 287 - Data transfer timeout now kills session. 288 - Take care that no writes block once we've decided to abandon ship. 289 - FreeBSD sendfile() support. I wonder if it works! 290 291 0.0.13 packaged 292 --------------- 293 294 - Split out directory listing code into ls.c 295 - Change blocking accept() and connect() code to use select() not SIGALRM! 296 - Remove alarm() timeout junk from file locking in logging.c 297 - Cater for signals interrupting the blocking file lock 298 - Whoops: fix data timeout incorrectly going off. Noted and fixed by Joshua 299 Hill <josh@untruth.org>. 300 - Implement tunable_pasv_promiscuous to relax PASV IP checks. Useful if you 301 are playing with secure tunneling of command connection. Idea, patch from 302 Seth Vidal <skvidal@phy.duke.edu>. 303 - Much better line-by-line file reading string buffer functions. 304 - Use the above better functions for directory messages and config file 305 reading. This eliminates a probable quadratic algorithm, i.e. it's a speedup. 306 - Explictly free certain buffers rather than using the static trick. For 307 example, the config file buffer which is only used once. 308 - Massive cleanup and refactoring of login code. 309 - Add ability to specify file containing list of banned e-mail addresses for 310 anonymous users. Apparently a required feature for big sites trying to avoid 311 DDoS attacks. 312 - Add ability to specify file containing list of users to chroot(), request 313 from helo <helo@neounix.com>, who also persuaded me not to use the homedir 314 hack in /etc/passwd. 315 - Add TODO: PASV port range config setting, for firewalled setups. From Rafal 316 Wojtczuk <nergal@idea.avet.com.pl>. 317 - Rudimentary support for non-PAM local user authentication, with 318 encouragement and helpful discussion from D Richard Felker III 319 <dalias@aerifal.cx>. 320 - Use MAP_ANON instead of mmap() /dev/zero for anonymous pages. It saves 321 using a file descriptor. Neither are standard(?) but MAP_ANON seems to work 322 on a superset of systems compared with mmap() /dev/zero. 323 - Ability to specify a PASV local port range with pasv_min_port and 324 pasv_max_port. Request from Rafal Wojtczuk <nergal@idea.avet.com.pl>. 325 - Non-PAM authentication: check /etc/shells, and support shadow password and 326 account expiry. 327 - First cut at a vsftpd.conf man page! (vsftpd.conf.5) 328 329 0.0.14 packaged 330 --------------- 331 332 - Default to ASCII mode transfers, as per RFC. Bug noted with Macintosh client 333 by William Day <day@chem.duke.edu>. 334 - Implement "ls -a". 335 - Implement "ls -r". 336 - Implement "ls -l", i.e. "NLST -L" now works 337 - Implement "ls -t". Superb - now the oft-used "ls -ltr" works! 338 - setproctitle() support - FreeBSD only in the first cut. 339 - setproctitle() on Linux support - what a hack! This crap really needs kernel 340 support. I'm ashamed I bothered. 341 - Repair the contributed spec files a bit, based on reports from Oleg Drokin 342 <green@iXcelerator.com> and Jakob Lichtenberg <jl@it-c.dk>. 343 - Show remote IP and local username in setproctitle() support. 344 - Add vsftpd.8 man page, thanks to Daniel Jacobowitz <dan@debian.org>. 345 - In sysdeputil.c, check macros LINUX_VERSION_CODE and KERNEL_VERSION are 346 defined. From James Antill <james@and.org>. 347 - Workaround a broken firewall that expects a very precise PASV response. We 348 now match wu-ftpd. Many many thanks to Jakob Lichtenberg <jl@it-c.dk> for 349 his help. 350 - If tunable_anon_world_readable_only (default), don't list directories unless 351 they are world readable. 352 - Use qsort() for directory sorting - eliminates gross quadratic sorting. 353 Turbo charges directory listings with 1000's of entries. 354 - Fix big memory leak in str_list_free(). 355 - Simplify + reduce heap usage in strlist.c 356 - Optimize away lots of excessive heap usage and redundant copying in str.c 357 - By default, show numeric user/group id's in directory listings. Makes 358 generating directory listings perhaps 4 times(!) faster, and is noticeable 359 with e.g. 5000 entries in a directory. n.b. this performance figure is as 360 measured on a glibc-2.2 system, so glibc would seem to be inefficient. 361 - Don't use MSG_DONTWAIT - prefer the more portable fcntl()/O_NONBLOCK. Fixes 362 glibc-2.0 build issues. 363 - Work around broken Linux-2.0 unix fd passing. Now builds/runs on RH5.2. 364 - Build fixes for FreeBSD 3.5, with help from Jerry Walsh <jerry@aardvark.ie>. 365 - Only restrict directory listings to world-readable for _anonymous_ users! 366 Thanks again Jerry Walsh <jerry@aardvark.ie> for the report. 367 - Add TUNING 368 - Special case for security/performance: if we need _no_ privilege, then 369 force one process model. Security: root dropped totally straight away. 370 Performance: no messing around forking etc. 371 - Minor performance tweaks, don't leave big mappings lying around from 372 config file parsing. 373 374 0.0.15 packaged 375 --------------- 376 377 - Argh. Fix SuSE 6.0 build issue (time_t used but not defined). Reported by 378 Peter Stern <peter@frontierflying.com>. 379 - Another SuSE 6.0 issue - another damn system lacking CMSG_SPACE etc. 380 - Cope with any return value from blocking close(2). Previously, we missed 381 EAGAIN, which some systems might return (not Linux). 382 - New wizzy synchronous signal framework, to prevent re-entrancy issues. It 383 presents an interface very similar to the traditional UNIX async interface. 384 Technically this is a security fix; imagine a SIGURG (user controllable!) 385 coming in whilst we are deep inside glibc. The SIGURG handler is non-trivial 386 and may well re-enter and upset glibc. Specific example: the malloc subsystem. 387 - When handing SIGURG, account the time taken under the data tranfer timeout. 388 - Install the command timeout handler before we write anything to the remote. 389 - Cleanup capabilities handling to be taken care of in secutil.c. 390 - Fix bug: one_process_model mode could lose supplementary groups. 391 - Add "SIZE" file. 392 - Make one_process_model work with the anon deny e-mail list. 393 - Massive cleanups. Start moving static state into a session structure. 394 - Oops - fix Solaris 8 build by fixing include order in porting_junk.h, and 395 include a dirfd() replacement. Noted by William Yodlowsky 396 <wyodlows@andromeda.rutgers.edu> and Mike Batchelor <mikebat@tmcs.net>. 397 - Fix return of a void function call in a void function. It upsets Sun's 398 compiler. (gcc is fine with it, I'm not sure if it's against the rules). 399 Noted by Mike Batchelor <mikebat@tmcs.net>. 400 - Make it possible to use port ranges starting lower than 5001, from 401 Matthew Kirkwood <weejock@ferret.lmh.ox.ac.uk>. 402 - Use a /dev/zero mmap() fallback if we do not find MAP_ANON. This should 403 fix the build on Solaris 2.6, 2.7 machines. Reported by Mike Batchelor 404 <mikebat@tmcs.net>. Also noted as one of the problems facing an IRIX build. 405 - Add MDTM support, so clients like ncftp can set the date on downloaded files. 406 - Add irix_bogons.h, trying to port to IRIX 6.5, with help from Jan-Frode 407 Myklebust <janfrode@parallab.uib.no>. 408 - Don't reference "struct msghdr.msg_flags", not all systems have it. Clear it 409 with vsf_sysutil_memclr() instead. Found on IRIX 6.5.11 410 - Cater for systems lacking getusershell(), e.g. IRIX 6.5.11, by not using it. 411 - Fix compiler error with header files claiming 2.4 headers but only having 412 2.2 headers. Reported by Ben Ricker <bricker@wellinx.com>. 413 - Kill warning on system without capabilities. 414 - Add -R option to ls (disabled by default), to cater for broken clients which 415 assume it is present (e.g. mirror). 416 - Add "Makefile.sun", from Mike Batchelor <mikebat@tmcs.net>. 417 - Fix PORT transfer crashes with "one_process_model". Reported by 418 Andrew Anderson <andrew@redhat.com>. 419 - Cater for HP-UX shared libraries which end in ".sl", from Kevin Vajk 420 <kvajk@cup.hp.com>. 421 - Add hpux_bogons.h, and make MAP_ANON a synonym for MAP_ANONYMOUS. 422 - Move send_fd and recv_fd to sysdeputil.c and provide old-style fd passing 423 code for IRIX and HP-UX. 424 - Get it going on HP-UX 11.11 and HP-UX 10.20, thanks to Kevin Vajk 425 <kvajk@cup.hp.com>. Minor changes to hpux_bogons.h 426 - Update vsftpd.conf with "ls_recurse_enable". 427 - Get it going on IRIX 6.5.11, thanks to Jan-Frode Myklebust 428 <janfrode@parallab.uib.no>. 429 - Fix reporting of filenames in MKD operations (regression since 0.0.15). 430 - Wow - lots of contributed .spec files. Adopt those from Seth Vidal 431 <skvidal@phy.duke.edu>. 432 - Fix FreeBSD build. 433 434 0.9.0 packaged 435 -------------- 436 437 - Fix .spec files to include URL, from Seth Vidal <skvidal@phy.duke.edu>. 438 - Don't let unprintable characters escape into setproctitle(). Thanks to 439 Solar Designer for the suggestion. 440 - Make the PAM service name a tunable, suggestion from Solar Designer. 441 - Add option to log all FTP protocol (log_ftp_protocol). 442 - Log logins, successful or failed. 443 - Refuse to download a file in ASCII mode if REST position != 0. Solar 444 reminded me by looking in the BUGS file. 445 - Clearly mark an ASCII download in the FTP response string. 446 - Argh.

The behaviour when 644 enabled is very wu-ftpd like. 645 - Implement SITE HELP - should work around IE bug? 646 - Update README, vsftpd.conf with references to read the manual page! 647 - Log revamp: add dual_log_enable to log to xferlog AND vsftpd.log. 648 - Log revamp: add syslog_enable to log vsftpd.log to syslog(). 649 - Add "background" option to background the listener process. 650 - Fix warning is vsftpd.8 man page, Bill Nottingham <notting@redhat.com>. 651 - Fix tcp wrappers support to NOT emit loads of Bad file descriptor messages 652 to the system log. 653 - Add ability to make bandwidth limiter smoother by using e.g. 654 trans_chunk_size=8192. 655 - Add ability for virtual users to use local privs non anon privs, via 656 virtual_use_local_privs=YES. 657 - Fix sendfile() fallback on FreeBSD, thanks to Adam Stroud 658 <adstro@stny.rr.com>. 659 - Add pam_session support, as well as utmp and wtmp logging for local logins 660 (when using a PAM build). Tested pam_limits maxlogins works. 661 - Ensure the source IP address for PORT connects is always the same as the 662 control connection local IP address. Previously it was not when NOT using 663 connect_from_port_20 in the presence of multiple local IP addresses. 664 - Oops - make max_per_ip and max_clients work with the two process model 665 when both connect_from_port_20 and chown_uploads are false. 666 - Initial IPv6 support (EPSV only). 667 - Add EPRT support to IPv6. 668 - Fix "ls .file" to list .file even if the ls -a flag is not present.

These should 715 NOT be used for securing content as they are very dumb! Filesystem permissions 716 are still the recommended way for securing important content. 717 - Allow unsetting of string values with option= (i.e. blank). 718 - Default virtual users to being chroot()'ed to the guest_user's home 719 directory, if virtual_use_local_privs is not set. 720 - Add support for "user_sub_token", where you can set the home directory of 721 guest_user to "/home/virtual/$USER", and "user_sub_token" to "$USER" to 722 have a root directory auto generated based on username logging in, e.g. 723 fred logs in and gets chroot()'ed in /home/virtual/fred. 724 - Fix bug in str_replace_text if replace token matches at end of string. 725 - Recognize P@SW as PASV; works around an SMC router bug. 726 - Accept an async ABOR sequence if it arrives via non-urgent data. Fixes issue 727 with Cisco routers. Thanks to Eddie Corns <E.Corns@ed.ac.uk>. 728 - Implement simple {,} support in pattern matcher (nested not handled). Handy 729 to use with hide_file and deny_file options. 730 (v1.2.1pre2) 731 - Fix port range with pasv_min_port and pasv_max_port to use the full range 732 (the upper limit wasn't being used very often!). 733 - Activate SO_REUSEADDR on passive listen sockets - makes servers with 734 restricted port ranges much more useable! 735 - Add secure_email_list_enable, to provide simple anonymous password control. 736 For some cases, it's better than the hassle of virtual users. Idea thanks to 737 Malcolm O'Callaghan, <mjo@stamps.com>. 738 - Add some FAQ entries. 739 (v1.2.1pre3) 740 - Fix issue with failure to call openlog() before using tcp_wrappers. Part 741 of RH bugzilla #89765. (The more serious part was fixed with v1.2.0). 742 743 At this point: v1.2.1 released! 744 =============================== 745 746 - Fix FreeBSD 5.1/5.2 issue with time_t being long long on that platform. 747 Thanks to Matthias Andree <matthias.andree@gmx.de>. 748 - Tweak vsftpd.conf.5 to avoid automated mails from ESR ;-) 749 - Remove vsftpd spec files, they are old and buggy. 750 - Add -v flag which just outputs the version and exits. 751 - Fix nasty issue resulting in listener instability under extreme load (root 752 cause was re-entering malloc/free). Many thanks to Olivier Baudron 753 <olivier.baudron@m4x.org> for an excellent report. 754 (v1.2.2pre1) 755 - Fix build with modern glibc-2.3 and no libcap on Linux. 756 - Fix 64-bit file support on Solaris. 757 (v1.2.2pre2) 758 - Add initial support for running as the user which launched vsftpd, i.e. no 759 root needed. Warning - easy to create insecurity if you use this without 760 knowing what you are doing. 761 - For above run-as-launching-user support: make CDUP re-use CWD code so that 762 deny_file of *..* is useful. 763 - Attempt fix of 64-bit file support on FreeBSD (may need another go). 764 - Update INSTALL to refer to more modern platforms. 765 766 At this point: v1.2.2 released! (need to get the listener fix out) 767 ================================================================== 768 769 - Improve logging (log deletes, renames, chmods, etc. as requested by users). 770 - Add no_log_lock to work around Solaris / Veritas locking hangs. 771 - Add EPRT, EPSV, PASV and TVFS to FEAT response. 772 - Implement use of MDTM to set timestamps. 773 - Recognize FEAT prior to login. 774 - Add OpenSSL (AUTH TLS / SSL) support for encrypted control and data 775 connections! Hurrah. 776 - Increase max size of .message files to 4000 characters, thanks to Eric 777 Pancer <epancer@security.depaul.edu> for the report. 778 - Add easy builddefs.h ability to disable PAM builds even when PAM is installed. 779 - Report vsftpd version in STAT output. 780 - Add REFS file. 781 - Change parent<->child socket comms from DGRAM to STREAM for increased 782 reliability. The main benefit is should the parent be killed (or crash out) 783 then the child won't block on a read() that will never return. 784 - Make str_reserve reserve space for the trailing zero as well, so we don't 785 cause a reallocation if we exactly fill the buffer. 786 - Optimize the sending of strings over the parent<->child comms links. 787 - Improve the build system so tcp_wrappers, PAM and OpenSSL can be forcibly 788 compiled out. 789 - Fix vsftpd.conf.5 typos, thanks to Dmitry V. Levin <ldv@altlinux.org>. 790 - If trans_chunk_size is between 1 and 4096, use 4096 rather than ignoring 791 totally. Thanks to Brad <brad@intradonline.com>. 792 - Lose Makefile.sun and README.solaris special cases. 793 - Add SSL / TLS info to SECURITY texts. 794 - Add README.ssl 795 - Add documentation for new SSL options to vsftpd.conf.5. 796 - Add support for CWD ~ (and in general support ~ at start of any filename). 797 Also support stuff like ~chris/pics, if tilde_user_enable=YES is set. Note that 798 all of this is for very very broken clients :-( 799 - Fix compile warnings. 800 - Update INSTALL with (recent) OS X as a working platform. 801 802 At this point: v2.0.0 released! 803 =============================== 804 805 - Add -lcrypto for the SSL build; needed for some systems! Thanks to Nelson 806 Chang <nelsoncybernet@bigfoot.com>. 807 - Oops; fix session bale out if an empty length password is given. 808 - Fix build on Fedora Core 2 (-lcap cannot seem to find /lib/libcap.so). 809 - Fix vsftpd.conf.5 man page error in "ssl_sslv3", thanks to Etienne Chevillard 810 <echevillard@yahoo.fr>. 811 - Clarify licensing: I allow linking of my GPL software with the OpenSSL 812 libraries. Thanks to Jonas Bofjall <job@abc.se>. 813 - Add COPYRIGHT. 814 - Fix build on OpenBSD, FreeBSD, probably NetBSD too (they aren't SuSv2 815 compliant; timezone should be a variable not a function). 816 - Fix build where PAM build is enabled but PAM headers are missing. 817 - Fix build on RHEL3 (remove errant include from twoprocess.c). 818 819 At this point: v2.0.1 released! 820 =============================== 821 822 - Fix FAQ typo, thanks to Jose Santiago Oyervides Gonzalez 823 <jose.oyervides@elnorte.com>. 824 - Emit data transfer status messages (success / failure) after flushing and 825 waiting for the full data transfer to reach the client. This should help work 826 around buggy FTP clients such as FlashFXP, which is known to truncate files 827 incorrectly. 828 (v2.0.2pre1) 829 - Make str_empty actually allocate an empty string. 830 - Change the ASCII receive code to ONLY rip out \r if it is just before a \n; 831 someone finally complained about this. 832 (v2.0.2pre2) 833 - Enable AIX Large File Support #define from Tomas gren <stric@cs.umu.se>. 834 - Add a couple of FAQ entries. 835 - Fix time delta code areas to cope with negative deltas, which will occur 836 if the clock is adjusted backwards. Thanks to Andrew Anderson 837 <andrew@redhat.com> for a great report. 838 - Fix "errno" checks to be robust in multiple places; previously, calls to 839 failing library calls could be made inbetween the original library call and 840 the "errno" reads. Thanks to Andrew Anderson <andrew@redhat.com> for a great 841 report. 842 - Make bandwidth limiter work with SSL data connections. 843 (v2.0.2pre3) 844 - Note that the SSL / bandwidth limiter bug fixed a much more serious bug: 845 SSL data connection dropouts after data_connection_timeout seconds. 846 - Typo fixes. 847 848 At this point: v2.0.2 released! (need to get the SSL dropout fix out) 849 ===================================================================== 850 851 - Document what regex expressions are supported in the man page. 852 - New settings rsa_private_key_file and dsa_private_key_file to allow 853 separate files for the certificates and private keys. 854 - Initial, simple fix for timed out processes not exiting when SSL is in use. 855 Better fix (which reports timeout to client properly) to follow. 856 - Add which setsockopt option failed to die("setsockopt") calls. 857 - Fix when running on recent OpenBSDs - OpenBSD change broke vsftpd. Lower 858 linger timeout from INT_MAX to 32767 (SHORT_MAX). Reported by 859 Ewoud van der Vliet <e.c.vandervliet@student.utwente.nl> and Ed Vazquez 860 <ed.vazquez@dhha.org>. 861 (v2.0.3pre1) 862 - Fix error with IPv4 connections to IPv6 listeners and PORT type data 863 connections when connect_from_port_20 is set. RedHat bugzilla 134541.

Reported 875 by Lee Lawrence <leel@aspin.co.uk> (using CuteFTP and BackupEdge) and 876 Christian DELAIR <christian@cognition.fr> (using lftp, FileZilla and 877 SmartFTP). Thanks to these two people for valuable help. 878 (v2.0.3pre2) 879 - Implicitly disable connect_from_port_20 and chown_uploads when a non-root 880 user is using run_as_launching_user. 881 - Add force_anon_logins_ssl and force_anon_data_ssl for a fully SSL secure 882 anonymous-only solution (useful when you don't have root access and a range 883 of acceptable anonymous passwords as credentials). 884 - Use SSL BIO callbacks to fix data connection timeout checks; the checks 885 weren't all occurring promply. 886 887 At this point: v2.0.3 released! (need to get about three imporant fixes out) 888 ============================================================================ 889 890 - Add explicit "This FTP server does not allow anonymous logins" message. 891 - Add paranoid checks to sysutil.c for large values / lengths. 892 - Fix incorrect comment about ASCII and SIZE in the vsftpd.conf example. 893 - Load per-IP config files earlier; allows more settings to be tuned on a 894 per-IP level. Suggested by Reber Tobias <t.reber@dkfz-heidelberg.de>. 895 - Fix MDTM on non-existant files. Reported by Ken A <ka@pacific.net>. 896 - {} regex fix so that {*} correctly matches everything. Reported by 897 Tom Van de Wiele <tom.vandewiele@gmail.com>. 898 - Add "mdtm_write" option to disable MDTM being able to set file timestamps. 899 - Fix HPUX build, thanks to Kevin Vajk <kvajk@cup.hp.com>. 900 - Add optional file locking support via lock_upload_files (default on). 901 - Apply LDFLAGS patch from Mads Martin Joergensen <mmj@suse.de>. 902 - Add pasv_addr_resolve option to allow pasv_address to get DNS resolved once 903 at startup. 904 - Apply patch to fix timezone issues (caused by chroot() interacting badly with 905 newer glibc versions). Thanks to Dmitry V. Levin <ldv@altlinux.org> and 906 Mads Martin Joergensen <mmj@suse.de>. 907 908 At this point: v2.0.4 released! 909 =============================== 910 911 - Apply fix for O_NONBLOCK vs. XFS DMAPI filesystem. Thanks to Sudha Srinivasan 912 <sudhas@sgi.com>. 913 - Fix build warnings exposed by my upgrade to Fedora Core 5 / GCC4.1.1. 914 - Be more honest in FEAT response if PORT or PASV are disabled! Reported by 915 Charles Honton <chas@honton.org>. Allows MS Explorer to get the transfer mode 916 correct. 917 - pam_pwdb.so -> pam_unix.so in example PAM file. Thanks to 918 Rhodes, Colin <colin.rhodes@airways.co.nz>. 919 - Add FAQ issue regarding "chroot fails with SSL" - in fact, sshd is being hit 920 here instead ;-) 921 - Minor man page doc tweaks. 922 - Tiny bit of paranoia in privops.c. 923 - Revert change to reject anonymous logins before asking for password. This 924 fixes complaints about IE not showing the FTP login dialog. 925 - Change SSL certificate load to cater for chaining too. 926 - Added delay_failed_login and delay_successful_login to help limit resources 927 taken by brute force attacks. 928 - Kick session after a few login fails. Allows IP blocking solutions to be more 929 immediately effective. 930 - Replace setenv() with more portable putenv(). First part of Solaris fix. 931 - Replace tm_gmtoff usage with timezone and daylight. Second part of Solaris 932 fix. 933 - Set PAM items TTY and RUSER if possible. 934 - OpenBSD build warning fixes. 935 - So, timezone and daylight are not available on BSD, so redo the whole TZ 936 thing again. Should use only very portable constructs now. 937 938 At this point: v2.0.5 released! 939 =============================== 940 941 - Fix delay_failed_login typo. Oops. 942 - Patch the getcwd and readlink sysutil helpers to reflect that they wouldn't 943 like a 0-sized buf. No caller is affected. Thanks Ilja van Sprundel 944 <ilja@suresec.org>. 945 - Allow a (fake) reauth as the same user as the logged in user. Should resolve 946 .NET related report from Sabo Jim <Jim.Sabo@thomson.net>. 947 - Tweak from Lucian Adrian Grijincu <lucian.grijincu@gmail.com> to take 948 unnecessary port calculations out of a loop. 949 - Fix byte I/O accounting in the error path of do_file_send_rwloop, thanks to 950 <echen@siac.com>. 951 - Don't log FireFox's attempts to RETR directories! Reported by 952 Nixdorf, Tim <tnixdorf@dnps.com>. 953 - Fix STOU sending the same 150 status line twice - oops! Reported by 954 <yamazaki@iij.ad.jp>. 955 - Fix xferlog format for virtual (guest) users, reported by Andy Fletcher 956 <andy@withnail.org>. 957 - Fix bug with empty user list file and userlist_deny=NO. Reported by 958 Marcin Zawadzki/GlobalVanet.com <marcin.zawadzki@globalvanet.com>. 959 - Pretend we have proper UTF8 support and respond positively to OPTS UTF8 ON. 960 Thanks Stanislav Maslovski <stanislav.maslovski@gmail.com>. 961 - Add control over the file permissions used in the chown()ing of anonymous 962 uploads: chown_upload_mode (default 0600 as before). Suggestion from 963 An Pham <apham@medforcetech.com>. 964 - Do a retry getting the active ftp socket in vsf_privop_get_ftp_port_sock(); 965 should help buggy Solaris systems. Reported by Michael Masterson 966 <mjmasterson@xo.com>. 967 - Add debug_ssl option to dump out some SSL connection details. 968 - Use code 522, not 521, to indicate that the server requires an encrypted 969 data connection. Still does not seem to coax lftp to retry :( 970 - Recognize OPTS pre-login. 971 - A whole ton of SSL improvements, including ability to force requirement of 972 a client cert; data and control channel client cert cross checking. Ability 973 to require fully valid / authentic client certs. No cert-based auth yet. 974 - Change my e-mail to my GMail account. 975 976 At this point: v2.0.6 released! 977 =============================== 978 979 - Fix finding libcap for the link on Slackware systems, thanks to Roman 980 Kravchenko <roman@atech.lv>. 981 - Fix build on Solaris 2.8 due to non-standard C, thanks to IIDA Yosiaki 982 <y-iida@secom.co.jp>. 983 - Fix man page typo, thanks Matt Selsky <selsky@columbia.edu>. 984 - Bring the PASV listen() into the bind() retry loop to resolve a race under 985 extreme load. Thanks to Curtis Taylor <cjt@us.ibm.com>. 986 - Enhance logging for debug_ssl. 987 - Shutdown the SSL data connections properly. This prevents clients such as 988 recent FileZilla from complaining. Reported by various people. 989 - Add option to enforce proper SSL shutdown on uploads. Left it off after much 990 agonizing because clients are so broken in this area. 991 - Add option to delete failed uploads. 992 993 At this point: v2.0.7 released! 994 =============================== 995 996 - Remove .postlogin.c.swp (thanks Kaibin Li <kbli@fortinet.com>)! 997 - findlibs repairs for libcap; builds on my Ubuntu 6.06 again. 998 - Apply patch to fix "error: assignment of read-only member '__in'" build 999 error on broken systems where the WIFEXITED() etc. macros write to their 1000 argument. Thanks Ingo Terpelle <it@exanto.de>. 1001 - Replace spaces in xferlog with underscores, report from 1002 Michael Wittauer <michael.wittauer@sonydadc.com>. 1003 - Reload default config values before re-parsing config file on SIGHUP. This 1004 makes the values correct in the case a setting was removed from the file. 1005 - Do not issue an FTP response for a blank line on the control channel. Fixes 1006 issues with some broken NAT devices. ProFTPd does the same, so hopefully 1007 nothing will break. Report from Frank Bulk <fbulk@mypremieronline.com>. 1008 - Replace usage of broken _syscall() with syscall(). Fixes build errors for 1009 those without libcap-devel installed. 1010 - Add implicit SSL support with implicit_ssl option. 1011 - Remove arbitrary restriction on one process model + SSL. 1012 - Set a session ID on the SSL context. 1013 - Add the skeleton of a built-in ptrace sandbox. Not yet useful for anything 1014 other than catching compile errors. Yes, I'm crazy :P 1015 - Use PR_SET_PDEATHSIG all over the place so that when the listener is killed, 1016 existing sessions are booted too. 1017 - Use SSL_peek; makes SSL pipelining work. Note that I never found any SSL 1018 client that need it, but still a nice code clean-up. 1019 - Change ASCII download behaviour so \r\n does not become \r\r\n. This mirrors 1020 proftpd behaviour instead of wu-ftpd. Thanks Paul Abel <pabel@fexcodcc.com>. 1021 - Switch all sighandlers to the synchronous ones. Prevents us having to 1022 block and unblock signals all the time. 1023 - Add a "use alarm" option to synchronous signal handlers, to ensure the race 1024 condition against a blocking call does not result in a permanent 1025 non-delivery. 1026 - Use SIGTERM for privileged parent process shutdown, so they can still update 1027 u/wtmp properly. 1028 - Do RAND_load_file from /dev/urandom in the child context because I don't 1029 trust the OpenSSL API vs. fork(). Different children do have different RNG 1030 state; this is defense in depth. 1031 - More thoroughly close the remote ends of the priv_sock, ensuring that child 1032 death results in no blocking in the parent. This is a matter of tidyness; the 1033 SIGCHLD handler will reliably tear down the parent. 1034 - Do the same for the SSL slave / consumer channels. 1035 - Fix OpenBSD build. 1036 - Move SSL data handling into the SSL slave process. Incurs some extra 1037 overhead in terms of context switches and copies, but it enables this next 1038 item: 1039 - By default, require SSL data connections to exhibit SSL session re-use of 1040 the control channel. Unlike the cert thing, this _is_ something we can turn 1041 on by default as most clients seem to do reuse. Yay. 1042 - Change 522 response for SSL connection fail to note when session reuse is 1043 required. 1044 (v2.1.0pre1 here) 1045 - More work on the inbuilt ptrace()-sandbox support. 1046 - Clear the idle alarm when starting data transfer if there is no data alarm. 1047 - Fix syslog format; don't embed 2nd copy of date, pid. Thanks to 1048 René Berber <r.berber@computer.org>. 1049 - Lock file before truncating it for upload. Fixes various simultaneous 1050 upload corruption issues. 1051 - Make sure to give 426 error code on uploads if ABOR was received. 1052 - Add cmds_denied option to complement cmds_allowed. 1053 - Ignore lines in config file containing only white space. 1054 - Require write_enable / anon_upload_enable / etc. to process STOU. 1055 - FC10 patch (vsftpd-1.0.1-missingok.patch): tweak to logrotate file. 1056 - FC10 patch (vsftpd-1.2.1-nonrootconf.patch): bail if the config file is not 1057 owned by the currently running user. 1058 - FC10 patch (vsftpd-2.0.1-tcp_wrappers.patch): explicitly call openlog() to 1059 avoid syslog() bug where some settings are not initialized. 1060 - FC10 patch (vsftpd-2.0.3-daemonize_fds.patch): when backgrounding, replace 1061 fd 0,1,2 with /dev/null fd. 1062 - FC10 patch (vsftpd-2.0.5-correct_comments.patch): comment tweaks in the 1063 sample config file. 1064 - FC10 patch (vsftpd-2.0.5-fix_unique.patch): use the default filename given 1065 by STOU if it is available. 1066 - FC10 patch (vsftpd-2.0.5-pam_end.patch): call pam_end() properly so modules 1067 can act on errors if they want. 1068 - FC10 patch (vsftpd-2.0.5-pasv_dot.patch): Strict RFC compliance for PASV 1069 command; add a trailing period. 1070 - FC10 patch (vsftpd-2.0.5-uname_size.patch): allow longer usernames. It's not 1071 1990 any more, so trust PAM etc. to not stack-buffer-overflow. 1072 - FC10 patch (vsftpd-2.0.5-underscore_uname.patch): permit username to start 1073 with underscore or period. 1074 - FC10 patch (vsftpd-2.0.6-listen.patch): default listen to YES. 1075 - Fix crash on SIGHUP introduced in 2.1.0pre1. Oops. 1076 - FC10 patch (vsftpd-2.0.5-bind_denied.patch): retry PASV bind() on EACCES 1077 too, which can happen on SELinux systems. 1078 - Default resource limit for child processes: 100MB address space. 1079 - Finishing touches to the initial sandbox policy; only permit connect() to 1080 the host on the control channel being the nicest touch. 1081 (v2.1.0pre2 here) 1082 - Fix 64-bit build (oops)! Thanks Martin Nagy <mnagy@redhat.com>. 1083 - Fix config of SSL built in; not enabled; two process model. Report from 1084 Martin. 1085 - Shutdown the command connection in the priv parent's SIGTERM handler; kills 1086 of children where the PR_SET_PDEATHSIG cannot due to different user ids. 1087 (v2.1.0pre3 here) 1088 - Fix build on FC10. 1089 - Some FAQ tweaks. 1090 - Permit fcntl(F_GETFD) in sandbox policy. Needed for FC10. Not sure where it 1091 comes from but it is harmless. (My guess would be glibc-2.9's new support for 1092 using O_CLOEXEC more). 1093 - Fix build warning on 64-bit. 1094 - Fix build on OpenBSD again. 1095 (v2.1.0pre4 here) 1096 - Bring userlist_deny handling inside the max_login_fail accounting. 1097 1098 At this point: v2.1.0 released! 1099 =============================== 1100 1101 - Apply Tavis' RLIMIT_NOFILE trick in the twoprocess model's initial 1102 unprivileged child. 1103 - Fix build error due to __NR_utimes. 1104 - Ugh. Can't use RLIMIT_NOFILE in the SSL case because the process later 1105 receives data transfer fd's via recvmsg(). It's a total shame because doing 1106 the SSL handshake under even lower privs would be a real boost. 1107 (v2.1.1pre1 here) 1108 - Fix some declarations occuring in the middle of a block; broke older more 1109 strict compilers. 1110 - Handle the case where libcap is now libcap.so.2; fixes build on my new 1111 Ubuntu 9.04. 1112 - Enhance 522 error message to point to require_ssl_reuse option. 1113 - Fix NASTY regression whereby data transfer timeouts would fire incorrectly 1114 under SSL transfers. In addition, the transfer rate caps were not working 1115 under SSL transfers. Reported by several people. 1116 - Use the login delay machinery for userlist-based denials too. Thanks to 1117 Tomas Hoger <thoger@redhat.com> for the patch. 1118 - Fix another tedious regression whereby absent per-user config files were 1119 causing a session fail rather than being gracefully ignored. 1120 - Use the somewhat new CLONE_NEWPID / CLONE_NEWIPC to provide more isolation 1121 in the vsftpd low-priv processes (CLONE_NEWNET pending). 1122 - Use RLIMIT_NPROC to disallow fork()ing etc. in processes that do not need 1123 to create new ones. 1124 - Add "isolate" config flag to disable the new weird clone() flags if 1125 necessary. 1126 1127 At this point: v2.1.1 released! 1128 =============================== 1129 1130 - Fix compile error in sysdeputil.c on some Linux systems. 1131 1132 At this point: v2.1.2 released! 1133 =============================== 1134 1135 - Fix compile on systems with no RLIMIT_NPROC, oops. 1136 - Change some unsigned int to socklen_t's to avoid warnings on various 1137 platforms, e.g. AIX. 1138 - Add some syscall constants to ptracesandbox.c to fix the build on systems 1139 with 2.4 kernel headers. 1140 - Look for libs in /lib64 and /usr/lib64 too (Fixes Fedora 11 x86_64 compile). 1141 - Fix EACCES mapping, thanks Solar Designer <solar@openwall.com>. 1142 - Dont emit a bogus "OOPS: " message upon a QUIT, report from Solar Designer 1143 <solar@openwall.com>. 1144 - Tweak example vsftpd.conf to add commented out chroot_local_user=YES, 1145 from Ivan I. Grushin <mcgru@intrice.ru>. 1146 - Where available, use CLONE_NEWNET to isolate the untrusted processes so that 1147 they can't do arbitrary connect() and instead have to ask the privileged 1148 process for sockets. Moderate code disturbance - hope for no breakage :-/ 1149 - Disable implicit activation of one_process_model so that an anonymous setup 1150 can benefit from the no-network isolation of the unprivileged process (where 1151 available). 1152 (vsftpd-2.2.0pre1) 1153 - Call pam_get_item(PAM_USER) after authentication in case a PAM module 1154 remapped the username. Based on a patch from John McNair <john.mcnair@ihg.com>. 1155 - Apply a couple of IPv6 fixes from Corinna Schultz <corinna.schultz@gmail.com>, 1156 particularly when MS operating systems are talking on link local addresses. 1157 - Handle the error case for accepting a PASV connection in the two process 1158 model properly. 1159 - Pull in a couple of minor tidyup patches from Openwall. 1160 - Add "-o" command line option to specify option, e.g. vsftpd -olisten=NO. Also 1161 respect ordering with respect config files, e.g. 1162 vsftpd -olisten=NO /etc/vsftpd.conf -olocal_enable=NO 1163 Inspiration from Solar / Openwall. 1164 (vsftpd-2.2.0pre2) 1165 - Revert listen to be "NO" by default and also set max_per_ip / max_clients 1166 to 2000 / 50 as a default. Thanks to Solar. 1167 - Sanity check for admin: check config files are regular files. 1168 - Error out if opening the per-user config file gives an error other than 1169 ENOENT. Thanks Solar (who is on fire today ;-) 1170 (vsftpd-2.2.0pre3) 1171 - Apply some typo fixes from Solar. 1172 - Error out on read() errors when reading config files. 1173 (vsftpd-2.2.0pre4) 1174 - Add tunable_isolate_network to parseconf.c, thanks Stefan Pfetzing 1175 <dreamind@dreamind.de>. 1176 - Don't try and use CLONE_NEWPID etc. if we get EPERM -- may happen even to 1177 root if using linux-vserver. Also thanks to Stefan Pfetzing 1178 <dreamind@dreamind.de>. 1179 - Couple of typo tweaks from Cristi Terpea <cristi.terpea@fortech.ro>. 1180 - Change // style comments to /* style. 1181 - Fix pointer aliasing issue in new PAM_USER item support, thanks to Solar. 1182 1183 At this point: v2.2.0 released! 1184 =============================== 1185 1186 - Apply patch to set SSL context timeout to maximum, from Tim Kosse 1187 <tim.kosse@filezilla-project.org>. Should prevent data connection failures 1188 after a long transfer or idle period. 1189 - Apply async-safety signal tweaks from Solar. 1190 - Fix crash regression with the pasv_address option enabled. 1191 - Typo fix and look for libnsl in /lib64, from Robby Workman 1192 <rworkman@slackware.com>. 1193 - When asking the client to send us a cert, make sure we broadcast some suitable 1194 certificates. Fixes compatibility with the z/OS FTP client when 1195 tunable_ssl_request_cert=YES. 1196 - Rip out the silly "cached time" concept. Simplifies things and fixes 1197 incorrect transfer time bug reported by Rajeev V. Pillai. Explicitly pass around 1198 the cached current time in seconds in the one place that needs to avoid 1199 repeated gettimeofday() calls (directory listing). 1200 - Do the login fail delay in the parent process for cases where we checked 1201 a username / password. 1202 1203 At this point: v2.2.1 released! 1204 =============================== 1205 1206 - Change "File receive OK." to "Transfer complete." to placate some broken 1207 clients. Thanks Holger Kiehl <Holger.Kiehl@dwd.de>. 1208 - Fix erroneous "child died" upon FTP client connect, when under load. Awesome 1209 thanks to Holger Kiehl <Holger.Kiehl@dwd.de> for running diagnostic tests on 1210 his live server. 1211 - Boot the session if an overly long line is encountered. 1212 (vsftpd-2.2.2pre1) 1213 1214 At this point: v2.2.2 released! 1215 =============================== 1216 1217 - Add extremely simply HTTP support. It's very experimental, ignorant of HTTP 1218 protocol and headers, and likely has all sorts of other issues. The use case 1219 it might satisfy is if you need to serve simple static unathenticated content 1220 with large levels of paranoia. 1221 - Fix port_promiscuous breakage. Report from Soeren <soeren84@fastmail.net>. 1222 (v2.3.0pre1) 1223 - Minor FAQ update. 1224 - Use a larger address space limit if using text_userdb_names=YES 1225 - Always use CLONE_NEWNET if possible when in HTTP mode. 1226 - Change REST + STOR so that it's possible to overwrite part of file without 1227 truncating it. 1228 (v2.3.0pre2) 1229 - Boot the session if we see a USER where encryption was required. May prevent 1230 the transmission of plaintext passwords by buggy clients. Idea from 1231 Marcin Hlybin <marcin@rootnode.net>. 1232 - Fix failure to transmit a large ASCII file over SSL, if it contains \n -> \r\n 1233 fixups. 1234 1235 At this point: v2.3.0 released! 1236 =============================== 1237 1238 - Fix silly regression re: log files being overwritten from the start. 1239 - Rename a few file-open functions to make it clearer what they do. 1240 1241 At this point: v2.3.1 released! 1242 =============================== 1243 1244 - Argh! Fix version number. 1245 1246 At this point: v2.3.2 released! 1247 =============================== 1248 1249 - Avoid consuming excessive CPU when matching filenames to patterns. Thanks to 1250 Maksymilian Arciemowicz <cxib@securityreason.com>. 1251 - Some bugfixes from Raphaël Rigo <raphael.rigo@syscall.eu> -- good bugs but 1252 no apparent security impact. 1253 1254 At this point: v2.3.3 released! 1255 =============================== 1256 1257 - Fix compile. Extreme suckage. 1258 1259 At this point: v2.3.4 released! 1260 =============================== 1261 1262 - Try and force glibc to cache zoneinfo files in an attempt to work around 1263 glibc parsing vulnerability. Thanks to Kingcope. 1264 - Only report CHMOD in SITE HELP if it's enabled. Thanks to Martin Schwenke 1265 <martin@meltin.net>. 1266 - Some simple fixes and cleanups from Thorsten Brehm <tbrehm@dspace.de>. 1267 - Only advertise "AUTH SSL" if one of SSLv2, SSLv3 is enabled. Thanks to 1268 steve willing <eiji-gravion@hotmail.com>. 1269 - Handle connect() failures properly. Thanks to Takayuki Nagata 1270 <tnagata@redhat.com>. 1271 - Add stronger checks for the configuration error of running with a writeable 1272 root directory inside a chroot(). This may bite people who carelessly turned 1273 on chroot_local_user but such is life. 1274 1275 At this point: v2.3.5 released! 1276 =============================== 1277 1278 - Update vsf_findlibs.sh to work on Ubuntu 11.10+ 1279 - Make listen mode the default. 1280 - Add -Werror to build flags. 1281 - Fix missing "const" in ssl.c 1282 - Add seccompsandbox.c to support a seccomp filter sandbox; works against Ubuntu 1283 12.04 ABI. 1284 - Rearrange ftppolicy.c a bit so the syscall list is easily comparable with 1285 seccompsandbox.c 1286 - Rename deprecated "sandbox" to "ptrace_sandbox". 1287 - Add a few more state checks to the privileged helper processes. 1288 - Add tunable "seccomp_sandbox", default on. 1289 - Use hardened build flags. Distros of course override these and provide their 1290 own build flags but no harm in showing how it could be done. 1291 - Retry creating a PASV socket upon port reuse race between bind() and listen(), 1292 patch from Ralph Wuerthner <ralph.wuerthner@de.ibm.com>. 1293 - Don't die() if recv() indicates a closed remote connection. Problem report 1294 on a Windows client from Herbert van den Bergh, 1295 <herbert.van.den.bergh@oracle.com>. 1296 - Add new config setting "allow_writeable_chroot" to help people in a bit of 1297 a spot with the v2.3.5 defensive change. Only applies to non-anonymous. 1298 - Remove a couple of fixed things from BUGS. 1299 - strlen() trunction fix -- no particular impact. 1300 - Apply some tidyups from mmoufid@yorku.ca. 1301 (vsftpd-3.0.0-pre1) 1302 - Fix delete_failed_uploads if there is a timeout. Report from Alejandro 1303 Hernández Hdez <aalejandrohdez@gmail.com>. 1304 - Fix other data channel bugs such as failure to log failure upon timeout. 1305 - Use exit codes a bit more consistently. 1306 - Fix bad interaction between SSL and trans_chunk_size. 1307 - Redo data timeout to fire properly for SSL sessions. 1308 - Redo idle timeout to fire properly for SSL sessions. 1309 - Make sure PROT_EXEC isn't allowed, thanks to Will Drewry for noticing. 1310 - Use 10 minutes as a max linger time just in case an alarm gets lost. 1311 (vsftpd-3.0.0-pre2) 1312 - Change PR_SET_NO_NEW_PRIVS define, from Kees Cook. 1313 - Add AES128-SHA to default SSL cipher suites for FileZilla compatibility. 1314 Unfortunately the default vsftpd SSL confiuration still doesn't fully work 1315 with FileZilla, because FileZilla has a data connection security problem: 1316 no client certificate presentation and no session reuse. At least the error 1317 message is now very clear. 1318 - Add restart_syscall to seccomp policy. Triggers reliably if you strace whilst 1319 a data transfer is in progress. 1320 - Fix delete_failed_uploads for anonymous sessions. 1321 - Don't listen for urgent data if the control connection is SSL, due to possible 1322 protocol synchronization issues. 1323 1324 At this point: v3.0.0 released! 1325 =============================== 1326 1327 - Fix some seccomp related build errors on certain CentOS and Debian versions. 1328 - Seccomp filter sandbox: missing munmap() -- oops. Did you know that qsort() 1329 opens and maps /proc/meminfo but only for larger item counts? 1330 - Seccomp filter sandbox: deny socket() gracefully for text_userdb_names. 1331 - Fix various NULL crashes with nonsensical config settings. Noted by Tianyin Xu 1332 <tixu@cs.ucsd.edu>. 1333 - Force cast to unsigned char in is* char functions. 1334 - Fix harmless integer issues in strlist.c. 1335 - Started on a (possibly ill-advised?) crusade to compile cleanly with 1336 Wconversion. Decided to suspend the effort half-way through. 1337 1338 At this point: v3.0.1 released! 1339 =============================== 1340 1341 - One more seccomp policy fix: mremap (denied). 1342 - Support STOU with no filename, uses a STOU. prefix. 1343 1344 At this point: v3.0.2 released! 1345 =============================== 1346 1347 - Increase VSFTP_AS_LIMIT to 200MB; various reports. 1348 - Make the PWD response more RFC compliant; report from Barry Kelly 1349 <barry@modeltwozero.com>. 1350 - Remove the trailing period from EPSV response to work around BT Internet 1351 issues; report from Tim Bishop <tdb@mirrorservice.org>. 1352 - Fix syslog_enable issues vs. seccomp filtering. Report from Michal Vyskocil 1353 <mvyskocil@suse.cz>. At least, syslogging seems to work on my Fedora now. 1354 - Allow gettimeofday() in the seccomp sandbox. I can't repro failures, but I 1355 probably have a different distro / libc / etc. and there are multiple reports. 1356 - Some kernels support PR_SET_NO_NEW_PRIVS but not PR_SET_SECCOMP, so handle 1357 this case gracefully. Report from Vasily Averin <vvs@odin.com>. 1358 - List the TLS1.2 cipher AES128-GCM-SHA256 as first preference by default. 1359 - Make some compile-time SSL defaults (such as correct client shutdown 1360 handling) stricter. 1361 - Disable Nagle algorithm during SSL data connection shutdown, to avoid 200ms 1362 delays. From Tim Kosse <tim.kosse@filezilla-project.org>. 1363 - Kill the FTP session if we see HTTP protocol commands, to avoid 1364 cross-protocol attacks. A report from Jann Horn <jann@thejh.net>. 1365 - Kill the FTP session if we see session re-use failure. A report from 1366 Tim Kosse <tim.kosse@filezilla-project.org>. 1367 (vsftpd-3.0.3pre1) 1368 - Enable ECDHE, Tim Kosse <tim.kosse@filezilla-project.org>. 1369 - Default cipher list is now just ECDHE-RSA-AES256-GCM-SHA384. 1370 - Minor SSL logging improvements. 1371 - Un-default tunable_strict_ssl_write_shutdown again. We still have 1372 tunable_strict_ssl_read_eof defaulted now, which is the important one to prove 1373 upload integrity. 1374 (vsftpd-3.0.3pre2) 1375 1376 At this point: v3.0.3 released! 1377 =============================== 1378 1379 - Fix build on Fedora 33 (one warning, one incorrect libcap used). 1380 - Fix SSL build (terrible grep for symbol in vsf_findlibs.sh)! 1381 - Fix runtime SIGSYS crashes on Fedora 33 (seccomp sandbox policy tweaks). 1382 - Reject HTTP verbs pre-login. 1383 - Disable TLS prior to v1.2 by default. 1384 - Close the control connection after 10 unknown commands pre-login. 1385 - Reject any TLS ALPN advertisement that's not 'ftp'. 1386 - Add ssl_sni_hostname option to require a match on incoming SNI hostname. 1387 1388 At this point: v3.0.4 released! 1389 =============================== 1390 1391 - Fix ALPN callback to correctly select the 'ftp' string if present. Works 1392 with FileZilla-3.55.0. 1393 - Fix a couple of seccomp policy issues with Fedora 34. 1394 1395 At this point: v3.0.5 released! 1396 ===============================
