2 Add IPv6 support. Patch by Karsten Keil.
4 Support systems with editline instead of readline.
6 Support long options in the server.
10 Unbreak -l -s in the server, which was broken in 0.47.
14 Add -L option to the server to run standalone without
15 detaching from the shell.
21 Minor portability improvements.
25 Add -l (literal) option to the client, to override the special
26 treatment of the colon (:) character as a hostname separator.
30 Allow the client to specify a range of local port numbers,
31 just like the server can.
33 Fix sending SIGHUP to update the regular expression table.
37 Fix double-free error on ^c in client.
39 Try to deal with clients that send TFTP requests to broadcasts
40 (apparently some recent Sun boxes do this instead of using the
41 address told by DHCP. Bad Sun! Bad Sun!)
47 Try to disable path MTU discovery for TFTP connections (it's
50 Add a hack to allow the admin to specify a range of local port
53 Fix local IP number handling on systems which present
54 IP_RECVDSTADDR in recvmsg().
58 Fix bug by which patterns of the form \U\1 weren't converted
67 Fix bug which would cause "r" remapping rules to be
72 Support Perl-style \U...\E and \L...\E, as well as allow
73 matching rules to be inverted (execute if rule *doesn't*
86 Fix a pathology where a client sending ACKs for the wrong
87 packet can prevent proper retransmission.
95 Add an option to control the maximum value of blksize
98 Removed workaround for obsolete Cygwin problem.
100 Don't use getopt() -- the -c option doesn't work correctly
101 since it depends on the ordering of arguments and options. It
102 is now possible to do:
104 tftp -m binary hostname -c get filename
106 This was previous possible by doing:
108 tftp -m binary -c get hostname:filename
110 ... but it seemed that was counterintuitive to people.
112 Somewhat improved configure scripts.
116 Additional Solaris gcc compiler bug workarounds; these
117 actually make the code somewhat cleaner.
121 Even better error messages.
123 Work around a suspect Solaris gcc bug.
125 Configuration fix: readline needs termcap.
127 Support running the tftp client from the command line. For
130 tftp -m binary -c get hostname:file
134 Better error messages; including the capability to send a
135 custom error message to the client when hitting an "a" rule in
140 Put in a check to make sure xinetd (in particular) doesn't
141 pass us an IPv6 socket.
143 Fix some problems related to timeout negotiation.
145 Allow the user to set the default timeout speed.
149 (Hopefully) better timeout algorithm.
151 Add a "utimeout" option; like "timeout" but in microseconds.
153 Change the log level of client-side errors to LOG_WARNING.
155 autoconf portability improvements.
163 Now compiles and runs on Win32 systems using Cygwin
164 (http://www.cygwin.com/).
165 (<http://www.cygwin.com/>).
167 Fixed a bug which could cause a standalone server to exit with
168 a "recvfrom: Interrupted system call" log message if signals
169 arrive at a particularly inopportune moment.
171 Fix a macro substitution bug (thanks to Richard Nyberg.)
175 Fix stupid one-liner bug which broke standalone mode (-l).
179 Make the Digital Unix 4.0F platform work again. Thanks to
180 Alan Sundell for helping out with this platform!
182 Make the AIX 4.3 platform work again. Thanks to Josef Siemes
183 for helping out with this platform!
185 Allow replacement patterns to include the IP address of the
186 requesting host (\i).
188 Allow relying on Unix permissions rather than o+r magic if the
189 -p option is specified. As part of this, set all groups if
190 initgroups() is specified on the platform.
192 Clean up race conditions inherited from the BSD source base.
196 Fix the configuration process so tftpd doesn't end up
197 depending on readline, which apparently could happen on some
200 Make parallel builds (make -j) work correctly.
202 Improve parsing of the "connect" command in the tftp client.
204 Add a -V option to both tftp and tftpd to print the version
205 number on stdout and immediately exit.
207 Add a -v option to tftp to start out in verbose mode.
209 Rewrite the man pages using standard "man" troff macros.
211 Enable the (limited) use of readline on systems which don't
212 have readline/history.h.
214 Support compiling under MacOS X with fink (see
215 <http://fink.sourceforge.net/>). Thanks for Justin Hallett
216 and Eric Eslinger for their help in getting this working!
220 Fixed Sorcerer's Apprentice bug in both the client and the
221 server. These bugs were inherited from the original BSD code.
225 Fix bugs in both client and server dealing with block number
226 wraparound, usually manifesting themselves as failure to
227 handle files over 32 MB in size.
229 Officially make the client a part of the tftp-hpa project.
233 Correct memory overwrite bug in the tftp client when compiled
238 Even more portability improvements: FreeBSD and
241 Fix tsize option on systems on which off_t is "long long".
243 Support large files on systems which need _LARGE_FILE_BITS or
246 Some source cleanups; change to autoconf 2.52.
248 Add support for readline command-line editing in tftp.
252 Support running in standalone mode, without inetd.
254 Even more portability improvements. Now known to compile and
255 run on Linux, Solaris 5, 5.1, 6, 7 and 8, and AIX. Reports of
256 success or failure on other modern systems always appreciated.
258 Clean and modernize some really ugly old code.
260 Fix a potential illegal memory access when running in "totally
261 insecure mode" - no -s, no directories listed.
265 Portability improvements. Now known to compile and run on
270 Fork before performing tcpwrappers check.
272 Don't rely on nonstandard bsd_signal() function, instead
273 require that the platform has sigaction(). This is 2001,
274 after all. This may resolve some potential portability
277 Log a message if memory allocation fails, instead of dying
280 Clean up the main dispatch loop.
282 Use <sysexits.h> for exit codes, if it exists.
284 Add support for debugging remapping rulefiles; if logging with
285 -vvv tftpd will log all rules actions.
287 Correct the error code issued by an "abort" rule.
291 Support (almost) arbitrary filename remappings via regular
292 expression-based rulesets.
294 Added -v option for more verbose logging.
299 Add support for tcpwrapper checking (/etc/hosts.allow;
300 /etc/hosts.deny) in tftpd.
302 Compile correctly on glibc 2.1.2.
304 Add -u option to specify the user id to run as (default
307 Operate in "daemon mode" as long as we keep getting requests.
308 This should speed up handling large amounts of requests at
309 once, as can happen when a client starts up, and avoids inetd
310 misconfiguration problems.
315 Correct massive lossage from 0.15: apparently 0.15 was based
316 on an out-of-date CVS repository, somehow.
318 Fix for ACKs in TFTP PUT; patch by Roger Venning.
323 If the operating system allows, try to obtain the local
324 address used for the request packet, and reply using the same
325 local IP address. Some embedded TFTP clients are (probably
326 incorrectly) picky about this.
331 Hacks to signal handling to avoid "zombie servers."
336 Added the non-standard option "blksize2". The "blksize"
337 option is limited in its usability, since TFTP is designed to
338 be implemented in a ROM, and ROM code might find it painful to
339 deal with packets that don't meet certain alignment
342 The "blksize2" option tells the server that the block size
343 must be a power of 2 to be usable to the client. The server
344 SHALL respond with a block size that is a power of two, up to
345 a maximum of 32768, or reject the option. Furthermore, the
346 server SHALL grant a block size that is no smaller than 512
347 bytes unless the client explicitly requested a smaller block
348 size. If the client request both options, the server MAY
349 accept one or the other, but not both. At some point I will
350 probably write up an IETF draft for this option.
353 General information on the tftp-hpa series:
355 The core software was taken from OpenBSD (CVS source as of
356 1999-09-21). I believe this was the most secure source base available
357 at the time I obtained this code, and it included support for the -s
360 The un-BSD-ized Makefiles and a lot of the configure macros were taken
361 from netkit-tftp-0.10 by David Holland; I also followed this example
362 and modernized the code style throughout.
364 Patches by Markus Gutschke and Gero Kuhlmann were the basis for the
365 option negotiation as well as the "blksize" and "tsize" option
366 support, although I made a fair amount of mostly stylistic changes to
369 Adding the -r option (disable a specific option), the "timeout"
370 option, converting to using autoconf for setup, and any additions
371 listed in the Changes list above, has all been my own code, as are any
372 bugs introduced in the merge.
