ae4f0fc3a9 Currently, if writing out a log entry fails, we unlink that log entry from our
internal list of logfiles. So if writev(2) fails for potentially transient
errors like ENOSPC, syslogd requires a restart, even if the filesystem has
purged.

This change allows syslogd to ignore ENOSPC space errors, so that when the
filesystem is cleaned up, syslogd will automatically start logging again
without requiring the reset. This makes syslogd(8) a bit more reliable.

cd70100e5d Optimize runtime performance, primary using the following techniques:
* Avoid choosing an arena until it's certain that an arena is needed
    for allocation.

  * Convert division/multiplication to bitshifting where possible.

  * Avoid accessing TLS variables in single-threaded code.

  * Reduce the amount of pointer dereferencing.

  * Move lock acquisition in critical paths to only protect the the code
    that requires synchronization, and completely remove locking where
    possible.

eb27a220f8 Expose res_update and friends again. At least, ports/mail/spamilter
uses them.
Now, we have res_nupdate and res_nmkupdate as well, but they are
still based on our old resolver for binary backward compatibility.
So, they don't provide new features such as TSIG support.

e59d4d98ef Fix more stack corruptions on amd64.
Vararg functions have a different calling convention than regular
functions on amd64. Casting a varag function to a regular one to
match the function pointer declaration will hide the varargs from
the caller and we will end up with an incorrectly setup stack.

Entirely remove the varargs from these functions and change the
functions to match the declaration of the function pointers.
Remove the now unnecessary casts.

Also change static struct ipprotosw[] to two independent
protosw/ip6protosw definitions to remove an unnecessary cast.

6174e6ed12 Add scc(4), a driver for serial communications controllers. These
controllers typically have multiple channels and support a number
of serial communications protocols. The scc(4) driver is itself
an umbrella driver that delegates the control over each channel
and mode to a subordinate driver (like uart(4)).
The scc(4) driver supports the Siemens SAB 82532 and the Zilog
Z8530 and replaces puc(4) for these devices.

8e88808915 md_hash field in g_eli_metadata structure is not 4 byte aligned, which
case panic on sparc64.

The problem is in MD5(9) implementation. The Encode() function takes
'unsigned char *output' as its first argument, which is then assigned to
'u_int32_t *op'. If the 'output' argument is not 4 byte aligned (and in
geli(8) case it is not), sparc64 machine will panic.

I don't know how to fix MD5(9) in a clean way, so I'm implementing a
work-around in geli(8).

03e21a94e4 Rebuild gensnmptree(1) on 700014 systems too. While 700014 corresponds
to post January 26 systems where gensnmptree(1) code was already fixed,
there was a timeframe between February 14 and February 27 when
usr.sbin/bsnmpd/ including gensnmptree was disconnected from build, so
if you upgraded in this timeframe, you ended up with the 700014 system
but still with a buggy gensnmptree binary.  This also means not being
able to buildworld now.

a49ed2a673 On some laptops, under very high loads, the socket event register read
in the ISR doesn't read the actual socket event register, but instead
reads garbage (usually 0xffffffff, but other times other things).
This totally violates the PCI spec, but happens rarely enough that a
workaround is in order.  This adds one test when we have a real
interrupt to service (which is very rare), and doesn't affect the
usualy 'nothing to see here' case at all.

Problem reported by many, but sam@ gave me this workaround after
diagnosing the problem.

4b3b0413d2 Always explicitly panic in propogate_priority() if we try to propogate
a lock's priority to a sleeping thread.  When we panic, dump a stack
trace of the thread that is asleep if DDB is compiled into the kernel
just before calling panic().  This is much more informative and useful
for debugging than the current behavior of getting a page fault and not
having an easy way of determining which thread caused the original problem.

dbcb35ffb9 Add a blacklist for bad IO ports that AML should never touch. It seems
some systems were designed so that AML writes to various resources shared
with OS drivers, including the RTC, PIC, PCI, etc.  These writes could
collide with writes by the OS and should never be performed.  For now, we
print a message if such an access occurs, but do not block it.  To block
the access, the tunable "debug.acpi.block_bad_io" can be set to 1.  In the
future, we will flip the switch and this will become the default.

Information about this problem was found in Microsoft KB 283649.  They
block IO accesses if the BIOS indicates via _OSI that it is Windows 2001
or higher.  They always block accesses to the PIC, cascaded PIC, and ELCRs,
no matter how old the BIOS.

9ed61314ff - We only lock the local per-CPU page in the local dTLB, so accessing the
foreign per-CPU pages in cpu_ipi_send() in order to get the module IDs
  of the other CPUs can cause a page fault. If this happens when doing a
  TLB shootdown while dealing with another page fault this causes a panic
  due to the recursive page fault. As I don't spot other code that assumes
  or requires that accessing foreign per-CPU pages must not page fault
  solve this by adding a statically allocated (and therefore locked in the
  kernel pages) array which establishes a FreeBSD CPU ID -> module ID
  relation and use that in cpu_ipi_selected() (instead of statically
  allocating the per-CPU pages which would just waste memory on say a dual
  CPU machine as sun4u theoretically supports up to 128 CPUs or wasting
  dTLB slots for the foreign per-CPU pages). [1]
- Fix a potential race in cpu_ipi_send(); as we don't serialize the access
  to cpu_ipi_selected() between MI and MD use (only MI-MI and MD-MD) we
  might catch the NACK bit caused by sending another IPI. Solve this by
  checking the NACK bit in the contents of the interrupt dispatch status
  reg read while interrupts were still turned off instead of reading that
  reg anew after interrupts were turned on again. This is also what the
  CPU docs suggest to do.
- Add a workaround for the SpitFire erratum #54 bug (affecting interrupt
  dispatch). While public info regarding what this CPU bug actually causes
  is not available testing shows that with the workaround in place it's
  less likely to get a "couldn't send ipi" panic, it doesn't solve these
  panics entirely though. [2]
