ba0b471d64 Break up a bunch of crazy if statements to use a case statement instead
to be cleaner.  Also, when deleting a chunk, try to find the mother chunk
as a whole chunk by default if this isn't a BSD partition or a unused or
whole chunk.  Before we just did this for FreeBSD and FAT slices, which
means that other chunk types such as EFI and mbr (mbr is used for slices
that don't have their own chunk type).

a5bf4e71ef Replace rev 1.33 with a real fix. The problem was integer overflows
when trying to store the year in a signed int.  The maximum time_t on ia64
is around 292 billion years in the future, but 'int' and struct tm.tm_year
can only represent then ext 2.1 billion years or so.

This solves the problem of mktime/localtime looping on ia64.  Unfortunately,
the standards say that tm_year is an 'int', so we are still stuck with a
y2147483647 bug.  bash2's configure script looks for bugs in mktime() and
fails on ia64 because of this.  However, mktime() on FreeBSD fails the test
normally anyway so this is no big loss.

This change does not affect any other platforms besides ia64.

4ce32d5dee Backed out previous commit (alignment suitable for RELENG_4) as planned
since it has been MFC'ed.  See the log message for the previous commit
for more details.  The alignment bug in gcc-3 has not been fixed, but
it is not very serious and the previous commit just moved it (as intended).

ada981b228 Create a new 32-bit fs_flags word in the superblock. Add code to move
the old 8-bit fs_old_flags to the new location the first time that the
filesystem is mounted by a new kernel. One of the unused flags in
fs_old_flags is used to indicate that the flags have been moved.
Leave the fs_old_flags word intact so that it will work properly if
used on an old kernel.

Change the fs_sblockloc superblock location field to be in units
of bytes instead of in units of filesystem fragments. The old units
did not work properly when the fragment size exceeeded the superblock
size (8192). Update old fs_sblockloc values at the same time that
the flags are moved.

f51c1e897d Rework the sysconf(3) interaction with aio:
sysconf.c:
  Use 'break' rather than 'goto yesno' in sysconf.c so that we report a '0'
  return value from the kernel sysctl.

vfs_aio.c:
  Make aio reset its configuration parameters to -1 after unloading
  instead of 0.

posix4_mib.c:
  Initialize the aio configuration parameters to -1
  to indicate that it is not loaded.
  Add a facility (p31b_iscfg()) to determine if a posix4 facility has been
  initialized to avoid having to re-order the SYSINITs.
  Use p31b_iscfg() to determine if aio has had a chance to run yet which
  is likely if it is compiled into the kernel and avoid spamming its
  values.
  Introduce a macro P31B_VALID() instead of doing the same comparison over
  and over.

posix4.h:
  Prototype p31b_iscfg().

f8739dd5f9 Implement the lock with a cmpxchg instruction instead of a xchg.
Both are atomic, but the cmpxchg has memory ordering hints. We
give this acquire semantics.

NOTE: The unlock in libc_r is implemented by a "normal" assign
statement. This is not correct on ia64 due to the memory ordering
characteristics of the architecture. We need release semantics
for an unlock.

3d8ce33a50 Provide more correct default values for sysconf(3) reporting of the AIO
subsystems capabilities:

_SC_AIO_LISTIO_MAX returns the default of _POSIX_AIO_LISTIO_MAX
_SC_AIO_MAX returns the default _POSIX_AIO_MAX
_SC_AIO_PRIO_DELTA_MAX returns the default of 0

Without these adjustments the values returned are -1 even when the
aio side of the kernel returns '0' for them which is incorrect.

6ceeb6902a utmp.ut_time and lastlog.ll_time are explicitly int32_t rather than
time_t.  Deal with the possibility that time_t != int32_t.  This boils
down to this sort of thing:
 -   time(&ut.ut_time);
 +   ut.ut_time = time(NULL);
and similar for ctime(3) etc.  I've kept it minimal for the stuff
that may need to be portable (or 3rd party code), but used Matt's time32
stuff for cases where that isn't as much of a concern.

7ea630865e Define `Sudden_Underflow' when compiling for the Alpha
architecture, mainly to avoid getting a SIGFPE signal sent
when calling strtod(3) with certain input.

The SIGFPE has been sent because the code was not aware that
a Gradual Underflow is handled in software via traps on the
Alpha architecture, but is not implemented in our Alpha kernel
layer.

With `Sudden_Underflow' defined, strtod(3) should not depend
on Gradual Underflow and adjust its calculations accordingly,
which means that other, more subtle errors than the sending of
SIGFPE could be solved by this.

bedff4e805 Reset LogTag to NULL in closelog(3). This fixes mysterious crashes
caused by dynamic PAM modules that call openlog(3) and closelog(3),
e.g. ports/security/pam_pwdfile.

What happened here is that the module first registered its "ident"
with openlog(3), then PAM library unloaded module with dlclose(3),
and the next call to syslog(3) resulted in SIGSEGV.

122dd01309 o Fix _longjmp() to return 1 when the return value is given as 0.
o  Remove the unwanted smartness in _longjmp() where it compares
   the current ar.bspstore with the saved ar.bspstore and restores
   ar.rnat based on it. This either avoids saving ar.rnat in the
   jmp_buf or is the consequence of not saving ar.rnat. All this
   complexity breaks libc_r where we use longjmp() to switch to
   different threads and the current ar.bspstore has no relation
   to the saved ar.bspstore. Thus: we save ar.rnat in setjmp()
   and simply restore ar.bspstore and ar.rnat in longjmp().

This code needs a cleanup.

7c2274dc95 The pam_krb5 module stored a reference to a krb5_ccache structure as
PAM module state (created in pam_sm_authenticate and referenced later
in pam_sm_setcred and pam_sm_acct_mgmt).  However, the krb5_ccache
structure shares some data members with the krb5_context structure
that was used in its creation.  Since a new krb5_context is created
and destroyed at each PAM entry point, this inevitably caused the
krb5_ccache structure to reference free'd memory.

Now instead of storing a pointer to the krb5_ccache structure,
we store the name of the cache (e.g. `MEMORY:0x123CACHE') in
pam_sm_authenticate, and resolve the name in the other entry points.

This bug was uncovered by phkmalloc's free'd memory scrubbing.

88c8bcce6c Use krb5_get_err_text' instead of error_message' so that instead of
e.g.

   Unknown error: -1765328378

we get

   Client not found in Kerberos database

Another way to accomplish this would have been to leave
`error_message' alone, but to explicitly load the Kerberos com_err
error tables.  However, I don't really like the idea of a PAM module
dorking with global tables.
