MFC r1.19:

2006-08-12T18:31:56Z

- Improve and extend mark-up. - Don't use full path in .Nm (we just don't do that). - Correct some frivolous and poorly rendering language, such as using possessive case for .Nm or .Fl . - Use the same capitalization for "user ID" as in setuid(2) and getuid(2). - Bring SEE ALSO in accord with the text.

o Missed colon in getopt(3) argument makes tftpd(8) crash. Fix that.

NI_WITHSCOPEID cleanup. Neither RFC 2553 nor RFC 3493 defines

2005-05-13T16:31:11Z

NI_WITHSCOPEID, and our getaddrinfo(3) does nothing special for it, now.

- Use socklen_t.

- No need for 'fromlen' to have file scope. - Remove an unused variable.

Instead of "OpenFirmware", "openfirmware", etc. use the official spelling

2004-08-16T15:45:27Z

"Open Firmware" from IEEE 1275 and OpenFirmware.org (no pun intended). Ok'ed by: tmm

mdoc(7) fixes.

The call to setuid(2) subsequently causes setgroups(2) to fail. setgroups(2)

2004-06-30T18:58:19Z

requires super-user access in order to complete successfully. Move setgroups(2) to execute before setuid(2) so that it is successful.

Call tzset() at startup.

o Reduce path names in RRQ and WRQ packets by:

2004-06-21T08:01:16Z

Reducing "/+./" strings to "/" Reducing "/[^/]+/../" to "/" o Don't send an OACK when the result of the [RW]RQ is an error. These changes allow tftpd to interact with pxelinux.bin from the syslinux package. Whilst the path reducing code doesn't properly handle situations where the path component before the "/../" is a symlink to (say) ".", I would suggest that it does the right thing in terms of the clients perception of what their path string actually represents. This seems better than using realpath() and breaking environments where symlinks point outside of the directory hierarchy that tftpd is configured to allow.

- Close fd if fdopen(fd) fails.

- Format return () to resemble the one 5 lines up.
