a632deec30 Add an "options MP_WATCHDOG" to i386. This option allows one of the
logical CPUs on a system to be used as a dedicated watchdog to cause a
drop to the debugger and/or generate an NMI to the boot processor if
the kernel ceases to respond.  A sysctl enables the watchdog running
out of the processor's idle thread; a callout is launched to reset a
timer in the watchdog.  If the callout fails to reset the timer for ten
seconds, the watchdog will fire.  The sysctl allows you to select which
CPU will run the watchdog.

A sample "debug.leak_schedlock" is included, which causes a sysctl to
spin holding sched_lock in order to trigger the watchdog.  On my Xeons,
the watchdog is able to detect this failure mode and break into the
debugger, which cannot otherwise be done without an NMI button.

This option does not currently work with sched_ule due to ule's push
notion of scheduling, similar to machdep.hlt_logical_cpus failing to
work with that scheduler.

On face value, this might seem somewhat inefficient, but there are a
lot of dual-processor Xeons with HTT around, so using one as a watchdog
for testing is not as inefficient as one might fear.

ad3b9257c2 Add locking to the kqueue subsystem. This also makes the kqueue subsystem
a more complete subsystem, and removes the knowlege of how things are
implemented from the drivers.  Include locking around filter ops, so a
module like aio will know when not to be unloaded if there are outstanding
knotes using it's filter ops.

Currently, it uses the MTX_DUPOK even though it is not always safe to
aquire duplicate locks.  Witness currently doesn't support the ability
to discover if a dup lock is ok (in some cases).

d8939d82cb Add a new sysctl, debug.kdb.stop_cpus, which controls whether or not we
attempt to IPI other cpus when entering the debugger in order to stop
them while in the debugger.  The default remains to issue the stop;
however, that can result in a hang if another cpu has interrupts disabled
and is spinning, since the IPI won't be received and the KDB will wait
indefinitely.  We probably need to add a timeout, but this is a useful
stopgap in the mean time.

efa79eb77e - Introduce an uart_cpu_identify() which is implemented in uart_cpu_<arch>.c
and that can be used as an identify function for all kinds of busses on a
  certain platform. Expect for sparc64 these are only stubs right now. [1]
- For sparc64, add code to its uart_cpu_identify() for registering the on-
  board ISA UARTs and their resources based on information obtained from
  Open Firmware.
  It would be better if this would be done in the OFW ISA code. However, due
  to the common FreeBSD ISA code and PNP-IDs not always being present in the
  properties of the ISA nodes there seems to be no good way to implement that.
  Therefore special casing UARTs as the sole really relevant ISA devices on
  sparc64 seemed reasonable. [2]

f348e5ac4b Make hme(4), i.e. the PCI-variant, MI by reading the MAC address on sytems
without Open Firmware directly instead of using OF_getetheraddr(). This is
a bit painful though, as the MAC address is contained in the NA field of
the VPD of the EBus bridge, which is is another function of the same chip.
To make it worse, the VPD of the EBus bridge can't be accessed via the PCI
capability pointer but has to be digged out from the Boot PROM and has a
non-standard format.
The PCI VPD struct and macros used here should be part of the FreeBSD PCI
code nevertheless.

o reprobe children when a new driver is added to uhub
o fix the usbd_probe_and_attach to set the ivars to a malloc'd area, as well
  as freeing the ivars on child destruction.
o Don't delete children that don't attach. Evidentally, the need to do this
  is a common misconception.
o minor formatting foo that may violate style(9) at the moment, but keeps the

b7b6c9e6fa - Make OF_getetheraddr() honour the "local-mac-address?" system config
variable. If set to "true" OF_getetheraddr() will now return the unique
  MAC address stored in the "local-mac-address" property of the device's
  OFW node if present and the host address/system default MAC address if
  the node doesn't doesn't have such a property. If set to "false" the
  host address will be returned for all devices like before this change.
  This brings the behaviour of device drivers for NICs with OFW support/
  FCode, i.e. dc(4) for on-board DM9102A on Sun machines, gem(4) and hme(4),
  regarding "local-mac-address?" in line with NetBSD and Solaris.
  The man pages of the respective drivers will be updated separately to
  reflect this change.
- Remove OF_getetheraddr2() which was used as a stopgap in dc(4). Its
  functionality is now part of OF_getetheraddr().

6cbea71c82 Cause pfind() not to return processes in the PRS_NEW state. As a result,
threads consuming the result of pfind() will not need to check for a NULL
credential pointer or other signs of an incompletely created process.
However, this also means that pfind() cannot be used to test for the
existence or find such a process.  Annotate pfind() to indicate that this
is the case.  A review of curent consumers seems to indicate that this is
not a problem for any of them.  This closes a number of race conditions
that could result in NULL pointer dereferences and related failure modes.
Other related races continue to exist, especially during iteration of the
allproc list without due caution.

f13a7951e1 Add a note about RANDOM_IP_ID. 2004-08-14 16:16:01 +00:00
David Malone
1f44b0a1b5 Get rid of the RANDOM_IP_ID option and make it a sysctl. NetBSD
have already done this, so I have styled the patch on their work:

        1) introduce a ip_newid() static inline function that checks
        the sysctl and then decides if it should return a sequential
        or random IP ID.

        2) named the sysctl net.inet.ip.random_id

        3) IPv6 flow IDs and fragment IDs are now always random.
        Flow IDs and frag IDs are significantly less common in the
        IPv6 world (ie. rarely generated per-packet), so there should
        be smaller performance concerns.

The sysctl defaults to 0 (sequential IP IDs).

b295bdcded After completing a name lookup for a target UNIX domain socket to
connect to, re-check that the local UNIX domain socket hasn't been
closed while we slept, and if so, return EINVAL.  This affects the
system running both with and without Giant over the network stack,
and recent ULE changes appear to cause it to trigger more
frequently than previously under load.  While here, improve catching
of possibly closed UNIX domain sockets in one or two additional
circumstances.  I have a much larger set of related changes in
Perforce, but they require more testing before they can be merged.

One debugging printf is left in place to indicate when such a race
takes place: this is typically triggered by a buggy application
that simultaenously connect()'s and close()'s a UNIX domain socket
file descriptor.  I'll remove this at some point in the future, but
am interested in seeing how frequently this is reported.  In the
case of Martin's reported problem, it appears to be a result of a
non-thread safe syslog() implementation in the C library, which
does not synchronize access to its logging file descriptor.
