The major change is to process STAT sent as an OOB command w/o
breaking the current data transfer. As a side effect, this gives
better error checking in the code performing data transfers.
A lesser, but in no way cosmetic, change is using the flag `recvurg'
in the only signal-safe way that has been blessed by SUSv3. The
other flag, `transflag,' becomes private to the SIGURG machinery,
serves debugging purposes only, and may be dropped in the future.
The `byte_count' global variable is now accounting bytes actually
transferred over the network. This can give status messages looking
strange, like "X of Y bytes transferred," where X > Y, but that has
more sense than trying to compensate for combinations of data formats
on the server and client when transferring ASCII type data. BTW,
getting the size of a file in advance is unreliable for a number of
reasons in the first place. See question 18.8 of the Infrequently
Asked Questions in comp.lang.c for details.

add the working directory pathname to the log message if any of
such arguments isn't absolute. This has advantage over the old
way of logging that an admin can see what users are actually trying
to do, and where. The old code was also not too robust when it
came to a chrooted session and an absolute pathname.

In the old world (as the surrounding comment in makefile says), there
was the /usr/libexec/ld-elf.so.1 binary which is now a symlink to
/libexec/ld-elf.so.1. To symlink, we need to make sure that the
_target_ (and the target is /usr/libexec/ld-elf.so.1) doesn't have
"schg" flag set. A real solution is to protect the chflags call only if
target exists, like we do in usr.bin/tip/tip/Makefile.

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.
(and that is for now being worked around by a binutils patch).
The rtld code tested &_DYNAMIC against 0 to see whether rtld itself
was built as PIC or not. While the sparc64 MD code did not rely
on the preset value of the GOT slot for _DYNAMIC any more due
to previous binutils changes, it still used to not be 0, so
that this check did work. The new binutils do however initialize
this slot with 0. As a consequence, rtld would not properly initialize
itself and crash.
Fix that by introducing a new macro, RTLD_IS_DYNAMIC, to take the role
of this test. For sparc64, it is implemented using the rtld_dynamic()
code that was already there. If an architecture does not provide its
own implementation, we default to the old check.
While being there, mark _DYNAMIC as a weak symbol in the sparc64
rtld_start.S. This is needed in the LDSCRIPT case, which is however
not currently supported for want of an actual ldscript.
