AMD IOMMU: allocate rlookup_table with __GFP_ZERO

2009-01-14T17:44:08+00:00

Upstream commit 83fd5cc6481c6b7fa8b45f8a7e0aa7120213430b

This is pointer list and if we dereference an uninitialized pointer
later this results in a kernel crash at boot. Happens typically after
3-5 hours of rebooting.

AMD IOMMU: reset command buffer pointers manually

2009-01-14T17:44:07+00:00

Upstream commit cf558d25e5c9f70fa0279c9b7b8b4aed7cae9bd4

Under special circumstances the IOMMU does not reset the head and tail
pointer of its command ringbuffer to zero when the command base is
written. This causes the IOMMU to fetch random memory and executes it as
an command. Since these commands are likely illegal IOMMU stops fetching
further commands including IOTLB flushes. This leads to completion wait
errors at boot and in some cases to data corruption and kernel crashes.

drivers/net: starfire: Fix napi ->poll() weight handling

2009-01-14T17:44:07+00:00

commit 9a3de25544dadab1971847f28f33b1cd0d1770a6 upstream.

starfire napi ->poll() handler can return work == weight after calling
netif_rx_complete() (if there is no more work). It is illegal and this
patch fixes it.

parisc: disable UP-optimized flush_tlb_mm

2009-01-14T17:44:07+00:00

commit 5289f46b9de04bde181d833d48df9671b69c4b08 upstream.

flush_tlb_mm's "optimized" uniprocessor case of allocating a new
context for userspace is exposing a race where we can suddely return
to a syscall with the protection id and space id out of sync, trapping
on the next userspace access.

cciss: fix problem that deleting multiple logical drives could cause a panic

2009-01-14T17:44:06+00:00

commit d8a0be6ab7ba1ffa43e7ea0dcdde3e8b68d4f762 upstream.

Fix problem that deleting multiple logical drives could cause a panic.

It fixes a panic which can be easily reproduced in the following way: Just
create several "arrays," each with multiple logical drives via hpacucli,
then delete the first array, and it will blow up in deregister_disk(), in
the call to get_host() when it tries to dig the hba pointer out of a NULL
queue pointer.

The problem has been present since my code to make rebuild_lun_table
behave better went in.

    [SCSI] aacraid: fix driver failure with Dell PowerEdge Expandable RAID Controller 3/Di

but fail with tons of "aac_srb: aac_fib_send failed with status: 8195"
instead. This patch disables the quirk introduced in the change cited
above for those two controllers again.
