CID 976523: add FALLTHROUGH

branches: 1.44.2;


Add a -b flag so that clients that return their acknowledgements to the
broadcast address can inter-operate with the tftpd server.
Discussed in bin/49868

- complete renaming of -w to -c from 1.38
- update usage string to match
- this fixes PR/48234 by Jeff Woodall

Simplify error handling and make it actually return a useable error code.
(Maxime Villard)

Check snprintf for -1 (Maxime Villard)

Prevent buffer overflows; reported by Maxime Villard

branches: 1.39.2; 1.39.8;
Use __dead

Rename -w to -c by popular demand
(allow file 'c'reation - 'w'riting was always available, with some twist;
plus there's already such a feature elsewhere, so let's try to not
diverge needlessly)

tftpd(8): Add -w so files can be uploaded without requiring them
to be created before the upload. See the section on security
considerations before enabling. [hubertf 20100429]

Addresses PR bin/43164.

fix build

newer versions of NetBSD turn on -Wsign-compare

Sync usage with man page.

- add -p pathsep option
- make wrap to zero work, but produce a warning
While here:
- fix gcc warnings, in particular variable clobbered warnings
(compiling with fewer warnings does not really fix the problem)

fix shadowed variable

branches: 1.31.4; 1.31.6;
Remove the \n and tabs from the __COPYRIGHT() strings.

branches: 1.30.20;
change (mostly) int to socklen_t. GCC 4 doesn't like that int and
socklen_t are different signness.

Add (unsigned char) cast to ctype functions

Make sure we tzset() before chroot(); after passing that point
it may no longer be accessible for syslog() to format messages.

branches: 1.27.2;
Remove duplicated headers. Pointed out by Peter Postma in PR bin/24002.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22284, verified by myself.

Support negotiation and use of TFTP Option Extension (rfc 2347) for the
'blksize' option (rfc 2348) and the 'timeout' and 'tsize' options (rfc 2349).

Enable verbose debugging messages via tftpd.

convert to use getprogname()

convert to ansi knf
replace (sole use of) sprintf() with snprintf()
only syslog debug messages if logging

make sure we do not overrun packet buffer when we set error message string.

handle getnameinfo error properly

defs had 'short block' for blocksize; changed defs to be unsigned.
added note to tftpd.8 that this bug hits multiple tftp clients.

IPv6 support.

If opening files for writing, be sure to truncate.

Fix for bin/4637, mostly as discussed on current-users.
Allow relative file writes,
For relative file accesses, no longer continues searching dirlist once we find
_any_ file, even one for which we don't have access,
If no dirlist was given on the command line, apply same permissions check as
with 'absolute' requests before allowing access.

Remember the interface the request comes in on, so we will reply to the
same address. This fixes tftp'ing to lo0 aliases.

* implement -u user and -g group - to specify the username and/or
group to run as.
if -u isn't given, user defaults to "nobody".
if -g isn't given, group defaults to the primary group of user.
doesn't try and change uid or gid if they're already set ok.
should solve PR 4218.
* deprecate register
* deprecate trailing \n in syslog messages

const poisoning.

clean up a bit of cruft.

fix so syslog works after chroot, by adding LOG_NDELAY to openlog.

Use S_IS*(), not S_IF*.

WARNS?=1. merge lite-2.

get rid of supplementary groups.

The tftpd daemon must be invoked as root in order for the chroot()
call to succeed, and must give up those privledges as soon as the new
root has been aquired. Use setgid() & setuid() to explicitly set the
user and group IDs to non- priveleged values.

This change now requires tftpd to be executed by root. I haven't
studied the security implications of making it setuid root, so
inetd.conf needs to be changed to start it as root.

Fill in sin_len.

From Christos Zoulas <christos@deshaw.com>:
As promised. the problem was that tftpd would core dump if given no arguments.
I fixed it to use getopt. I also changed 0 to fd, because I had added some
debugging code that allowed me to start it from the command line.

Add -s flag, per Roland McGrath, with changes and a manual page addition by me.

Add RCS identifiers.

Cleanup for GCC 2.
