Using "putname()" without the underscores will leak memory, because the

Bryan Sutula [Wed, 5 Oct 2005 17:02:06 +0000 (11:02 -0600)]
[IA64] Avoid kernel hang during CMC interrupt storm

I've noticed a kernel hang during a storm of CMC interrupts, which was
tracked down to the continual execution of the interrupt handler.

There's code in the CMC handler that's supposed to disable CMC
interrupts and switch to polling mode when it sees a bunch of CMCs.
Because disabling CMCs across all CPUs isn't safe in interrupt context,
the disable is done with a schedule_work().  But with continual CMC
interrupts, the schedule_work() never gets executed.

The following patch immediately disables CMC interrupts for the current
CPU.  This then allows (at least) one CPU to ignore CMC interrupts,
execute the schedule_work() code, and disable CMC interrupts on the rest
of the CPUs.

[PATCH] libata: Marvell SATA support (DMA mode) (resend: v0.22)

This is my libata compatible low level driver for the Marvell SATA
family.  Currently it runs in DMA mode on a 6081 chip.

The 5xxx series parts are not yet DMA capable in this driver because
the registers have differences that haven't been accounted for yet.
Basically, I'm focused on the 6xxx series right now.  I apologize for
those seeing problems on the 5xxx series, I've not had a chance to
look at those problems yet.

For those curious, the previous bug causing the SCSI timeout and
subsequent panics was caused by an improper clear of hc_irq_cause in
mv_host_intr().

This version is running well in my environment (6081 chips,
with/without SW raid1) and is showing equal or better performance
compared to the Marvell driver (mv_sata) in my initial tests (timed
dd's of reads/writes to/from memory/disk).

ata11: status=0x35 { DeviceFault SeekComplete CorrectedError Error }
SCSI error : <10 0 0 0> return code = 0x8000002
Current sda: sense key Hardware Error
end_request: I/O error, dev sda, sector 3155010

and this, seen at init time:

ATA: abnormal status 0x80 on port 0xE093911C

but they aren't showstoppers.

Jeff Garzik [Tue, 4 Oct 2005 01:36:41 +0000 (21:36 -0400)]
[libata] improve device scan even more

Since our max_lun is unconditionally set to 1, we might as well
hardcode a LUN 0 probe, rather than a wildcard LUN scan.

The ide-scsi driver sets max_lun to a value greater than under
certain conditions:

        if ((drive->id->last_lun & 0x7) != 7)
                host->max_lun = (drive->id->last_lun & 0x7) + 1;
        else
                host->max_lun = 1;

last_lun is Word 126 of IDENTIFY PACKET DEVICE, marked as obsolete
and undocumented in non-ancient specs.  We'll leave it out for now.
Should the need arise to support multi-LUN ATAPI devices, we'll
probably want to add the above code.

Finally, there have been reports of REPORT LUNS commands locking up
ATAPI drives.  Eliminating the wildcard LUN scan could help reduce
the trouble from problematic drives.

[IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl

The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.

1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().

There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition.  I've marked it as such so that we remember to fix it.
