文件传输协议linux 下vsftpd2.1.0.tar.gz

- 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 <[e-mail]>.
- If trans_chunk_size is between 1 and 4096, use 4096 rather than ignoring
totally. Thanks to Brad <[e-mail]>.
- 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 <[e-mail]>.
- 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
<[e-mail]>.
- Clarify licensing: I allow linking of my GPL software with the OpenSSL
libraries. Thanks to Jonas Bofjall <[e-mail]>.
- 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
<[e-mail]>.
- 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 <[e-mail]>.
- 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
<[e-mail]> 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 <[e-mail]> 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 <[e-mail]> and Ed Vazquez
<[e-mail]>.
(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 <[e-mail]>, Radek Vokal <[e-mail]> and
Andreas Kupfer <[e-mail]>.
- 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 <[e-mail]> (using CuteFTP and BackupEdge) and
Christian DELAIR <[e-mail]> (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 <[e-mail]>.
- Fix MDTM on non-existant files. Reported by Ken A <[e-mail]>.
- {} regex fix so that {*} correctly matches everything. Reported by
Tom Van de Wiele <[e-mail]>.
- Add "mdtm_write" option to disable MDTM being able to set file timestamps.
- Fix HPUX build, thanks to Kevin Vajk <[e-mail]>.
- Add optional file locking support via lock_upload_files (default on).
- Apply LDFLAGS patch from Mads Martin Joergensen <[e-mail]>.
- 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 <[e-mail]> and
Mads Martin Joergensen <[e-mail]>.

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

- Apply fix for O_NONBLOCK vs. XFS DMAPI filesystem. Thanks to Sudha Srinivasan
<[e-mail]>.
- 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 <[e-mail]>. Allows MS Explorer to get the transfer mode
correct.
- pam_pwdb.so -> pam_unix.so in example PAM file. Thanks to
Rhodes, Colin <[e-mail]>.
- 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
<[e-mail]>.
- Allow a (fake) reauth as the same user as the logged in user. Should resolve
.NET related report from Sabo Jim <[e-mail]>.
- Tweak from Lucian Adrian Grijincu <[e-mail]> 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
<[e-mail]>.
- Don't log FireFox's attempts to RETR directories! Reported by
Nixdorf, Tim <[e-mail]>.
- Fix STOU sending the same 150 status line twice - oops! Reported by
<[e-mail]>.
- Fix xferlog format for virtual (guest) users, reported by Andy Fletcher
<[e-mail]>.
- Fix bug with empty user list file and userlist_deny=NO. Reported by
Marcin Zawadzki/GlobalVanet.com <[e-mail]>.
- Pretend we have proper UTF8 support and respond positively to OPTS UTF8 ON.
Thanks Stanislav Maslovski <[e-mail]>.
- 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 <[e-mail]>.
- Do a retry getting the active ftp socket in vsf_privop_get_ftp_port_sock();
should help buggy Solaris systems. Reported by Michael Masterson
<[e-mail]>.
- 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 <[e-mail]>.
- Fix build on Solaris 2.8 due to non-standard C, thanks to IIDA Yosiaki
<[e-mail]>.
- Fix man page typo, thanks Matt Selsky <[e-mail]>.
- Bring the PASV listen() into the bind() retry loop to resolve a race under
extreme load. Thanks to Curtis Taylor <[e-mail]>.
- 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 <[e-mail]>)!
- 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 <[e-mail]>.
- Replace spaces in xferlog with underscores, report from
Michael Wittauer <[e-mail]>.
- Reload default config values before re-parsing config file on SIGHUP. This
makes the values correct in the case a setting was removed from the file.
- Do not issue an FTP response for a blank line on the control channel. Fixes
issues with some broken NAT devices. ProFTPd does the same, so hopefully
nothing will break. Report from Frank Bulk <[e-mail]>.
- Replace usage of broken _syscall() with syscall(). Fixes build errors for
those without libcap-devel installed.
- Add implicit SSL support with implicit_ssl option.
- Remove arbitrary restriction on one process model + SSL.
- Set a session ID on the SSL context.
- Add the skeleton of a built-in ptrace sandbox. Not yet useful for anything
other than catching compile errors. Yes, I'm crazy :P
- Use PR_SET_PDEATHSIG all over the place so that when the listener is killed,
existing sessions are booted too.
- Use SSL_peek; makes SSL pipelining work. Note that I never found any SSL
client that need it, but still a nice code clean-up.
- Change ASCII download behaviour so \r\n does not become \r\r\n. This mirrors
proftpd behaviour instead of wu-ftpd. Thanks Paul Abel <[e-mail]>.
- Switch all sighandlers to the synchronous ones. Prevents us having to
block and unblock signals all the time.
- Add a "use alarm" option to synchronous signal handlers, to ensure the race
condition against a blocking call does not result in a permanent
non-delivery.
- Use SIGTERM for privileged parent process shutdown, so they can still update
u/wtmp properly.
- Do RAND_load_file from /dev/urandom in the child context because I don't
trust the OpenSSL API vs. fork(). Different children do have different RNG
state; this is defense in depth.
- More thoroughly close the remote ends of the priv_sock, ensuring that child
death results in no blocking in the parent. This is a matter of tidyness; the
SIGCHLD handler will reliably tear down the parent.
- Do the same for the SSL slave / consumer channels.
- Fix OpenBSD build.
- Move SSL data handling into the SSL slave process. Incurs some extra
overhead in terms of context switches and copies, but it enables this next
item:
- By default, require SSL data connections to exhibit SSL session re-use of
the control channel. Unlike the cert thing, this _is_ something we can turn
on by default as most clients seem to do reuse. Yay.
- Change 522 response for SSL connection fail to note when session reuse is
required.
(v2.1.0pre1 here)
- More work on the inbuilt ptrace()-sandbox support.
- Clear the idle alarm when starting data transfer if there is no data alarm.
- Fix syslog format; don't embed 2nd copy of date, pid. Thanks to
Ren
