0fe8d9f3dd Removed unused include of <kvm.h>. It was alarming for libc to apparently
depend on libkvm.

9a10bb17e1 Build structure for contribified Linux-PAM, plus some home-grown
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.

08f9fcbfa8 fetch_err.h is a generated file, so don't look for it in ${.CURDIR}. 1998-11-07 08:59:38 +00:00
Dag-Erling Smørgrav
d8acd8dc5c Second of a series of cleanups to libfetch.
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.

Changed files, in alphabetical order:

 Makefile:
  Don't generate macros in {ftp,http}err.c.

  Generate category fields for the error message lists.

  Compile the error table.

  Install fetch_err.h along with fetch.h.

 common.c:
  Remove the _netdb_errstring() macro, and add FETCH_ERR_NETDB to the
  error code in the _netdb_seterr() macro.

  Add categories to the _netdb_errlist table.

  Report errors through the Common Error library.

 common.h:
  Add the DEBUG macros.

  Add prototype for fetchConnect().

  Remove the prototype for _fetch_errstring(), which is local to common.c

  Add a categroy field to struct fetcherr, and define constants for
  error categories.

  Define macros for _{url,netdb,ftp,http}_seterr().

 errors.et: (new file)
  List error categories.

 fetch.3:
  Document the fetchStat*() functions.

  Move the "unimplemented functionality" comments from NOTES to BUGS.

  Document that applications which use libfetch must also use
  libcom_err, and list existing error codes.

  Undocument fetchLastErr{Code,String}.

  Remove the (empty) DIAGNOSTICS section.

  Mention Eugene Skepner in the AUTHORS section.

 fetch.c:
  Move the DEBUG macros to common.c

  Add fetchStat() and fetchStatURL().

  Generate error messages for URL parser errors, and fix a minor bug
  in the parser.

  Use 'struct url' instead of 'url_t'.

  Remove fetchLastErr{Code,String}.

 fetch.h:
  Use 'struct url' instead of 'url_t', and remove the typedef.

  Define struct url_stat (used by fetchStat()).

  Add prototypes for fetchStat*().

  Remove the declarations for fetchLastErr{Code,String}.

  Include fetch_err.h.

 fetch_err.et: (new file)
  Error table for libfetch.

 file.c:
  Add fetchStatFile().

  Use 'struct url' instead of 'url_t'.

 ftp.c:
  Add fetchStatFTP().

  Use 'struct url' instead of 'url_t'.

  Don't use fetchLastErrCode.

 ftp.errors:
  Add categories to all error messages.

 http.c:
  Add fetchStatHTTP().

  Use 'struct url' instead of 'url_t'.

  Don't use fetchLastErr{Code,Text}.

 http.errors:
  Add categories to all error messages.

  fails.

86854f0360 A feeble attempt at kld compatability. The mount_* programs assume that
they cannot mount a filesystem that they cannot see in getvfsbyname().
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).

Here's a quote From the PR:

 When wrefresh() is called with a subwindow as argument, __set_subwin
 might be called with reversed arguments if wrefresh() decides to calls
 quickch().  This may cause use of negative array indexes, with a
 resulting segfault.

 Since quickch() manipulates the line structures belonging to curscr,
 it looks like all subwindows of curscr should be updated.

in the wrong places for a while.
Also, the the libtermlib.so -> libtermcap.so manually for elf, otherwise
the hard link follows the symlink and the result looks rather wierd.  The
*.a files are still hard linked under elf as before.

0890dc6f44 vfork -> fork. The child calls execl() which calls malloc(), so
vfork() can't be used.  We could use alloca() in execl() so that
it can be called between vfork() and execve(), but a "portable"
popen() shouldn't depend on this.  Calling execle() instead of
execl() should be fairly safe, since execle() is supposed to be
callable from signal handlers and signal handlers can't call
malloc().  However, execle() is broken.

dc3a8b52c0 Move the cleanup code that frees memory allocated for a dead thread from
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.

a0aa389007 Delete the XXX comments that refer to spinlock recursion. The malloc/free/
realloc functions check for recursion within the malloc code itself. In
a thread-safe library, the single spinlock ensures that no two threads
go inside the protected code at the same time. The thread implementation
is responsible for ensuring that the spinlock does in fact protect malloc.
There was a window of opportunity in which this was not the case. I'll fix
that with a commit RSN.

d988805a1f Back out part of previous commit (even though it's technically correct).
Our spinlock implementation allows a particular thread to obtain a lock
multiple times, but release the lock with a single unlock call.  Since
we're detecting recursion, we know the lock is already owned by the
current thread in a previous call and must not be released in the
current call.  This is really far too dependent on this particular
spinlock implementation, so I've added commented out calls to
THREAD_UNLOCK in the appropriate places.  We can activate this code when
spinlock is taught to count each lock operation.
