9e06e6da51 Some adjustments for the resolver use of poll(). For some reason I thought 
an unimplemented syscall returned ENOSYS, rather than EINVAL.  I have run
statically linked code with this wrapper and it does appear to work fine
on 2.2-stable which doesn't have poll().  ktrace shows the poll syscall fail
once and the fallback to select() working.

b7ecb08afa Put a system call not present checking wrapper around the call to 
__getcwd().  I've got this libc code running on one of my machines
at the moment without the __getcwd() syscall being present.

27262cac33 Add __getcwd() syscall, and have getcwd() take a shot at it. 
If your kernel doesn't support __getcwd() or if __getcwd() cannot
deliver because of cache expiry, it does the canonical thing.

535db1806c Call poll(2) from within the resolver but adapt to older kernels without it 
if necessary.  This removes the need to malloc large fd_set's for selecting
on high fd's (larger than FD_SETSIZE at libc compile time).

The syscall adaptive stuff only happens on the very first call.  SIGSYS
is masked, and if the call to poll fails with ENOSYS, then we use select
for the life of the program.  If poll does not fail with ENOSYS, then we
always use poll and skip the once-off signal masking gunk.

This may be overkill, but it saved my neck a few times while working on
multiple different sets of kernel sources, some with poll, some without.

a9c87f32ee When compiling under elf, use correct library naming conventions. Also 
add the required extra symlink.  Set the -soname to libcrypt.so so that
the symlink is used at runtime rather than resolved at compile time.

7bd6d5e7cf If building under elf, have libskey.so depend on libmd and libcrypt. 1997-09-05 11:52:20 +00:00
Peter Wemm
1840bd1444 If not building a.out, still build a pic version of libmd. This allows 
things like libskey.so to be dynamically self contained.

Things like md5(1) where speed is critical should still link with libmd.a,
but for things like login, where it's a once-off call if skey is used, it's
not worth the hassle.

77909f5978 Initial elf nlist support, mostly stolen from OpenBSD (they use standard 
#defines that are compatable with ours).  I made some some minor tweaks
to the leading '_' tests.

Again, this is off by default for the moment.  This probably should be
split into seperate files (like some of our other libc files that could
do with some splitting).

9a91f1cc25 Merge in the safe chdir changes from Todd Miller's mods to the OpenBSD 
tree.  Also merge in fix to NetBSD PR #1495.  These represent 1.3-1.9 in
the OpenBSD tree.  Make minor KNF changes to new code (which is in the
OpenBSD as 1.10).  This avoids the symlink race problems.

These patches should go into 2.2.5 before the ship if they don't
break anything in -current.

9295bb8d0d Add a stub version of getpublickey(), in order to eliminate an 
undefined symbol referenced from libc.  Without the stub, it is
impossible to execute any program using the shared library if
LD_BIND_NOW=1 is in the environment.  The stub always returns
failure, but it can be overridden outside the library when necessary.

I don't know whether this is the "correct" fix, but it is intolerable
to have any undefined symbols referenced from libc.
