where shared libraries are in /lib and almost everything is linked
shared. First, they removed the old shared library before installing
the new one. Second, they attemped a cross-device link from /lib
to /usr/lib/compat.
following "panic:" or "Fatal trap". `panicstr' is still printed,
although it is redundant if there is a valid message buffer and
incomplete if it contains `%'s. I think the awk command belongs
here and not in a script since a standard format with complete
messages is good for bug reports.
out of bounds a_entry is a kernel and use the usual kludge to find
the text address). If gdb had used this, it would have been able
to find the kernel text address properly. Unfortunately, it uses
its own a.out macros, so this is mainly an example for gdb to copy.
following of the symlink for `rmdir symlink/' and is unnecessary
for ordinary directories (POSIX doesn't require rmdir(1) to do
anything for trailing slashes; it requires rmdir(2) to let them
"refer to a directory", and following the symlink for symlink/ is
what BSD does). This also fixes bugs in the slash-stripping code
(for paths consisting entirely of slashes, the pointer into the
string was decremented to "before" the beginning of the string,
and the path was at best stripped to "".
The behaviour is unchanged except for the final directory for
`rmdir -p ...'. There is no alternative to stripping intermediate
slashes since they must be specified. The sloppy slash-stripping
code is adequate for intermediate directories, since the all-slashes
case fails early.
don't remove a.out explicitly. a.out should only be generated for
libraries and is removed in the non-default rule in bsd.lib.mk.
Removed undocumented cleanfiles target. It was the same as the
default clean target except it didn't descend into subdirs. It was
different from special clean targets in other ways. This feature
hasn't been missed for more important targets.
Removed unused default cleandepend target. bsd.dep.mk has a better
version which is always used.
Use a better rule for checkdpadd in the BINFORMAT=aout case. This
mainly checks that ld -f is working correctly. The old rule is
still available via `make BINFORMAT=foo checkdpadd' and should be
used to check for regressions under 2.2 where ld -f is not available.
where if you are using the "reset tcp" firewall command,
the kernel would write ethernet headers onto random kernel stack locations.
Fought to the death by: terry, julian, archie.
fix valid for 2.2 series as well.
strcpy(a, b); /* a and b are the same size */
with
strncpy(a, b, sizeof(a));
a[sizeof(a)-1] = '\0';
Making the code `correct at a glance'.
