consider a linker set definition to be sufficient reason to pull an
object module from an archive library. This caused undefined
symbols when linking with libpam.a using a.out. I solved it by
linking in the object that references the linker set in the "ld -r"
step.
Secure Hashing Algorithm - 1 (SHA-1), along with the further
refinement of what $x$salt$hash means. With this new crypt the
following are all acceptable:
$1$
$MD5$
$SHA1$
Note: $2$ is used by OpenBSD's Blowfish, which I considered adding
as $BF$, but there is no actual need for it with SHA-1. However,
somebody wishing to add OpenBSD password support could easilly add
it in now.
There is also a malloc_crypt() available in the library now, which
behaves exactly the same as crypt(), but it uses a malloced buffer
instead of a static buffer. However, this is not standard so will
likely not be used much (at all).
Also, for those interested I did a brief speed test Pentium 166/MMX,
which shows the DES crypt to do approximately 2640 crypts a CPU second,
MD5 to do about 62 crypts a CPU second and SHA1 to do about 18 crypts
a CPU second.

modules for FreeBSD's standard authentication methods. Although
the Linux-PAM modules are present in the contrib tree, we don't
use any of them.
The main library "libpam" is composed of sources taken from three
places. First are the standard Linux-PAM libpam sources from the
contrib tree. Second are the Linux-PAM "libpam_misc" sources, also
from the contrib tree. In Linux these form a separate library.
But as Mike Smith pointed out to me, that seems pointless, so I
have combined them into the libpam library. Third are some additional
sources from the "src/lib/libpam" tree with some common functions
that make it easier to write modules. Those I wrote myself.

This commit introduces the following features:
a) the fetchStat*() functions, which return meta-information for a
document, such as size, modification time, etc.
b) the use of the com_err(3) facilities to report errors.
It also fixes a bunch of style bugs and a few logic bugs and somewhat
improves the man page.

Part 1 of this is a hack, make vfsisloadable() always return true - the
ultimate decider of whether it's loadable or not is kldload() or mount().
Part 2 of this is to have vfsload() call kldload(2) and return success if
it works. This means that we will use a viable kld module in preference
to an LKM!
Ultimately, the thing to do is remove the hacks to do a vfsload in all the
mount_* commands and let the kernel do it by itself in mount(2).

When wrefresh() is called with a subwindow as argument, __set_subwin

Since quickch() manipulates the line structures belonging to curscr,

the thread kernel into a garbage collector thread which is started when
the fisrt thread is created (other than the initial thread). This
removes the window of opportunity where a context switch will cause a
thread that has locked the malloc spinlock, to enter the thread kernel,
find there is a dead thread and try to free memory, therefore trying
to lock the malloc spinlock against itself.
The garbage collector thread acts just like any other thread, so
instead of having a spinlock to control accesses to the dead thread
list, it uses a mutex and a condition variable so that it can happily
wait to be signalled when a thread exists.
