Christoph Hellwig [Wed, 26 Jul 2006 07:53:23 +0000]
[PATCH] fix compile regression for a few scsi drivers

This fixes three drivers to compile again after my patch that removes
the data_cmnd member from struct scsi_cmnd.

The fas216 change is trivial, it should have been using ->cmnd all the
time.

NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing
something odd, it should only have looked at ->cmnd before not the saved
copy that is kept for the error handlers sake.  Note that it really
should deal with the sync setting themselves but use the generic domain
validation code that get this right - but that's for later let's push
this simple compile fix for now.

And sorry for the late fix for this, I have been busy with OLS and
associated activities last week.

13 years ago[PATCH] Reorganize the cpufreq cpu hotplug locking to not be totally bizare
Arjan van de Ven [Wed, 26 Jul 2006 13:40:07 +0000]
[PATCH] Reorganize the cpufreq cpu hotplug locking to not be totally bizare

The patch below moves the cpu hotplugging higher up in the cpufreq
layering; this is needed to avoid recursive taking of the cpu hotplug
lock and to otherwise detangle the mess.

The new rules are:
1. you must do lock_cpu_hotplug() around the following functions:
   __cpufreq_driver_target
   __cpufreq_governor (for CPUFREQ_GOV_LIMITS operation only)
   __cpufreq_set_policy
2. governer methods (.governer) must NOT take the lock_cpu_hotplug()
   lock in any way; they are called with the lock taken already
3. if your governer spawns a thread that does things, like calling
   __cpufreq_driver_target, your thread must honor rule #1.
4. the policy lock and other cpufreq internal locks nest within
   the lock_cpu_hotplug() lock.

I'm not entirely happy about how the __cpufreq_governor rule ended up
(conditional locking rule depending on the argument) but basically all
callers pass this as a constant so it's not too horrible.

The patch also removes the cpufreq_governor() function since during the
locking audit it turned out to be entirely unused (so no need to fix it)

The patch works on my testbox, but it could use more testing
(otoh... it can't be much worse than the current code)

Tetsuo Handa [Wed, 26 Jul 2006 00:05:35 +0000]
[IPV4/IPV6]: Setting 0 for unused port field in RAW IP recvmsg().

From: Tetsuo Handa from-linux-kernel@i-love.sakura.ne.jp

The recvmsg() for raw socket seems to return random u16 value
from the kernel stack memory since port field is not initialized.
But I'm not sure this patch is correct.
Does raw socket return any information stored in port field?

[ BSD defines RAW IP recvmsg to return a sin_port value of zero.
  This is described in Steven's TCP/IP Illustrated Volume 2 on
  page 1055, which is discussing the BSD rip_input() implementation. ]

I went to alter the default sysctl and it didn't take for new sockets.
Below patch fixes this.

I think the default is too low but it is what the DCCP spec specifies.

As a side effect of this my rx speed using iperf goes from about 2.8 Mbits/sec
to 3.5. This is still far too slow but it is a step in the right direction.

13 years ago[PATCH] Cpuset: fix ABBA deadlock with cpu hotplug lock
Paul Jackson [Sun, 23 Jul 2006 18:36:08 +0000]
[PATCH] Cpuset: fix ABBA deadlock with cpu hotplug lock

Fix ABBA deadlock between lock_cpu_hotplug() and the cpuset
callback_mutex lock.

It only happens on cpu_exclusive cpusets, due to the dynamic
sched domain code trying to take the cpu hotplug lock inside
the cpuset callback_mutex lock.

This bug has apparently been here for several months, but didn't
get hit until the right customer load on a large system.

This fix appears right from inspection, but it will take a few
more days running it on that customers workload to be confident
we nailed it.  We don't have any other reproducible test case.

The cpu_hotplug_lock() tends to cover large runs of code.
The other places that hold both that lock and the cpuset callback
mutex lock always nest the cpuset lock inside the hotplug lock.
This place tries to do the reverse, risking an ABBA deadlock.

This is in the cpuset_rmdir() code, where we:
  * take the callback_mutex lock
  * mark the cpuset CS_REMOVED
  * call update_cpu_domains for cpu_exclusive cpusets
  * in that call, take the cpu_hotplug lock if the
    cpuset is marked for removal.

Thanks to Jack Steiner for identifying this deadlock.

The fix is to tear down the dynamic sched domain before we grab
the cpuset callback_mutex lock.  This way, the two locks are
serialized, with the hotplug lock taken and released before
trying for the cpuset lock.

I suspect that this bug was introduced when I changed the
cpuset locking from one lock to two.  The dynamic sched domain
dependency on cpu_exclusive cpusets and its hotplug hooks were
added to this code earlier, when cpusets had only a single lock.
It may well have been fine then.

13 years agocpu hotplug: simplify and hopefully fix locking
Linus Torvalds [Sun, 23 Jul 2006 19:12:16 +0000]
cpu hotplug: simplify and hopefully fix locking

The CPU hotplug locking was quite messy, with a recursive lock to
handle the fact that both the actual up/down sequence wanted to
protect itself from being re-entered, but the callbacks that it
called also tended to want to protect themselves from CPU events.

This splits the lock into two (one to serialize the whole hotplug
sequence, the other to protect against the CPU present bitmaps
changing). The latter still allows recursive usage because some
subsystems (ondemand policy for cpufreq at least) had already gotten
too used to the lax locking, but the locking mistakes are hopefully
now less fundamental, and we now warn about recursive lock usage
when we see it, in the hope that it can be fixed.

[SERIAL] sunzilog: Fix instance enumeration.

Just do a linear enumeration so that we handle sun4d systems
correctly.  As a consequence, eliminate the hard coded keyboard and
mouse channel line values, use the CONS_{KEYB,MS} flags instead.

Also, report the keyboard/mouse Zilog channels just like the uart ones
do.

[SPARC64]: Fix more of_device layer IRQ bugs, and correct PROMREG_MAX.

Sabre and Psycho PCI controllers can have partial interrupt-map
properties, meaning that on-board devices don't match up to any
entries.  Instead, they are fully specified from the beginning and
we should pass them directly to the IRQ translator as-is.

Also, fill in the necessary translator slots for the "graphics"
and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS.

Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices.

Finally, prevent accidentally writing past the end of the of_device
struct resource[] and irqs[] arrays.  Spit out a log message when
we ignore some entries because there are too many of them.
