is stored in _res_ext.sort_list, and sortlist for IPv4 is stored in
_res.sort_list for backward compatibility. However, both sort_list's
are maintaind by just one index _res.nsort. So, when IPv6 address is
specified to sortlist, empty entry was created in _res.sort_list. It
broke sortlist facility of gethostbyname().

/usr/src/lib/libpam/modules/pam_ssh/pam_ssh.c has couple of bugs which cause:
1) xdm dumps core
2) ssh1 private key is not passed to ssh-agent
3) ssh2 RSA key seems not handled properly (just a guess from source)
4) ssh_get_authentication_connectionen() fails to get connection because of
SSH_AUTH_SOCK not defined.

than handling it as a side effect of the security profile. Update the
help file to reflect this change.
o Rename "Fascist" to "Extreme" in the source code, to match the names
presented to the user.
o Remove portmap and inetd from profile management. Portmap is now
disabled by default, but automatically turned on if a feature requires
it (such as NFS, etc).

structure is always free()ed yet only sometimes malloc()ed. In particular,
it was simply set to point to l_filename from the a linker_file_t in
link_elf_link_preload_finish(). The l_filename had been malloc()ed inside
the kern_linker.c module and was being free()ed twice: once by
link_elf_unload_file() and again by linker_file_unload(), leading to
a panic.
How to duplicate the problem:
- Pre-load a kernel module from the loader, i.e. if_sis.ko
- Boot system
- Attempt to unload module with kldunload if_sis
- Bewm
The problem here is that the case where the module was loaded with kldload
after system boot would work correctly, so this bug went unnoticed until
I stubbed my toe on it just now. (Also, you can only trip this bug if
you compile a kernel with options DDB, but that's the default now.)
Fix: remember to malloc() a separate copy of the module name for the
l_name member of the gdb linkage structure in three places where the
linkage structure can be initialized.
flags with interrupts disabled to see if we should call ast() during
doreti. This was mostly submitted by Bruce, but his original patch did
the looping in ast() in assembly rather than in the ast() function itself.
Once we've actually called into the ast() function, it's cheaper to just
loop inside the function rather than returning from the function,
performing the check, and then calling the function again. However, we
can optimize the first check to avoid calling the function at all.
Other architectures may choose to implement this optimization if they
wish but it is not required for correct operation.

the process of exiting the kernel. The ast() function now loops as long
as the PS_ASTPENDING or PS_NEEDRESCHED flags are set. It returns with
preemption disabled so that any further AST's that arrive via an
interrupt will be delayed until the low-level MD code returns to user
mode.
- Use u_int's to store the tick counts for profiling purposes so that we
do not need sched_lock just to read p_sticks. This also closes a
problem where the call to addupc_task() could screw up the arithmetic
due to non-atomic reads of p_sticks.
- Axe need_proftick(), aston(), astoff(), astpending(), need_resched(),
clear_resched(), and resched_wanted() in favor of direct bit operations
on p_sflag.
- Fix up locking with sched_lock some. In addupc_intr(), use sched_lock
to ensure pr_addr and pr_ticks are updated atomically with setting
PS_OWEUPC. In ast() we clear pr_ticks atomically with clearing
PS_OWEUPC. We also do not grab the lock just to test a flag.
- Simplify the handling of Giant in ast() slightly.

removing the callout entry, return 1. If callout_stop() fails to remove
the callout entry because it is currently executing or has already been
executed, then the function returns 0. The idea was obtained from BSD/OS,
however, BSD/OS changed untimeout(), and I've just changed callout_stop()
to be more conservative.
