[PATCH] s390: lcs driver bug fixes and improvements [1/2]
Several problems occured with lcs device driver:
- device not operational anymore after cable pull/plug-in.
- unpredictable results occured, e.g. kernel panic
using cards of type QD8F.
- STOPLAN and delete multicast address command
were not proper recognized by OSA card under heavy network workload.
- channel/device error checks missing in interrupt handler.
To fix all problems at once recovery of lcs devices has been improved.
missing error checks in lcs interrupt handler has been added.
Once a hardware problem occurs lcs will recover the device now properly.

From: Frank Blaschka <Frank.Blaschka@de.ibm.com>
From: Frank Pavlic <fpavlic@de.ibm.com>
- fix fake_ll during initial device bringup. fake_ll was
not active after first start of the device.
Problem only occured when qeth was built without IPV6 support.
- avoid skb usage after invocation of qeth_flush_buffers,
because skb might already be freed.
- remove yet another useless netif_wake_queue in
qeth_softsetup_ipv6 since this function is only called
when device is going online. In this case card->state will
never be in state UP. So let the net_device queue down .

handler would initialize s_rdma_sge, then node A's sending thread would
update s_rdma_sge. This didn't happen very often naturally but was more
frequent with 1 byte RDMA reads. Rather than adding more locking or

each barrier thus messed up statistics.
This patch makes bar_rq not accounted as normal IO. As the containing

[PATCH] md: fix possible oops when starting a raid0 array
This loop that sets up the hash_table has problems.
Careful examination will show that the last time through, everything but
the first line is pointless. This is because all it does is change 'cur'
and 'size' and neither of these are used after the loop. This should ring
warning bells... That last time through the loop,
size += conf->strip_zone[cur].size
can index off the end of the strip_zone array. Depending on what it finds
there, it might exit the loop cleanly, or it might spin going further and
further beyond the array until it hits an unmapped address.
This patch rearranges the code so that the last, pointless, iteration of
the loop never happens. i.e. the one statement of the last loop that is
needed is moved the the end of the previous loop - or to before the loop
starts - and the loop counter starts from 1 instead of 0.

[SPARC64]: Respect gfp_t argument to dma_alloc_coherent().
Using asm-generic/dma-mapping.h does not work because pushing
the call down to pci_alloc_coherent() causes the gfp_t argument
of dma_alloc_coherent() to be ignored.
Fix this by implementing things directly, and adding a gfp_t
argument we can use in the internal call down to the PCI DMA
implementation of pci_alloc_coherent().
This fixes massive memory corruption when using the sound driver
layer, which passes things like __GFP_COMP down into these

[NETFILTER]: SNMP NAT: fix memory corruption
Fix memory corruption caused by snmp_trap_decode:
- When snmp_trap_decode fails before the id and address are allocated,
the pointers contain random memory, but are freed by the caller
(snmp_parse_mangle).
- When snmp_trap_decode fails after allocating just the ID, it tries
to free both address and ID, but the address pointer still contains
random memory. The caller frees both ID and random memory again.
- When snmp_trap_decode fails after allocating both, it frees both,
and the callers frees both again.
The corruption can be triggered remotely when the ip_nat_snmp_basic
module is loaded and traffic on port 161 or 162 is NATed.

[PATCH] Align the node_mem_map endpoints to a MAX_ORDER boundary
Andy added code to buddy allocator which does not require the zone's
endpoints to be aligned to MAX_ORDER. An issue is that the buddy allocator
requires the node_mem_map's endpoints to be MAX_ORDER aligned. Otherwise
__page_find_buddy could compute a buddy not in node_mem_map for partial
MAX_ORDER regions at zone's endpoints. page_is_buddy will detect that
these pages at endpoints are not PG_buddy (they were zeroed out by bootmem
allocator and not part of zone). Of course the negative here is we could
waste a little memory but the positive is eliminating all the old checks
for zone boundary conditions.
SPARSEMEM won't encounter this issue because of MAX_ORDER size constraint
when SPARSEMEM is configured. ia64 VIRTUAL_MEM_MAP doesn't need the logic
either because the holes and endpoints are handled differently. This
leaves checking alloc_remap and other arches which privately allocate for
node_mem_map.

Check SHT_REL sections as like as SHT_RELA sections to detect section

[PATCH] s390: next_timer_interrupt overflow in stop_hz_timer
The 32 bit unsigned substraction (next - jiffies) in stop_hz_timer can
overflow if jiffies gets advanced between next_timer_interrupt and the read
under the xtime lock. The cast to a u64 then results in a large value
which causes the cpu to wait too long. Fix this by casting next and
jiffies independently to u64 before subtracting them.

[PATCH] Fix a NO_IDLE_HZ timer bug
Under certain timing conditions, a race during boot occurs where timer
ticks are being processed on remote CPUs. The remote timer ticks can
increment jiffies, and if this happens during a window when a timeout is
very close to expiring but a local tick has not yet been delivered, you can
end up with
1) No softirq pending
2) A local timer wheel which is not synced to jiffies
3) No high resolution timer active
4) A local timer which is supposed to fire before the current jiffies value.
In this circumstance, the comparison in next_timer_interrupt overflows,
because the base of the comparison for high resolution timers is jiffies,
but for the softirq timer wheel, it is relative the the current base of the
wheel (jiffies_base).

If we put a probe onto a callq instruction and the probe is executed,
kernel panic of Bad RIP value occurs.
Root cause:
If resume_execution() found 0xff at first byte of p->ainsn.insn, it must
check the _second_ byte. But current resume_execution check _first_ byte
again.
I changed it checks second byte of p->ainsn.insn.
Kprobes on i386 don't have this problem, because the implementation is a

[PATCH] i386 kdump boot cpu physical apicid fix
o Kdump second kernel boot fails after a system crash if second kernel
is UP and acpi=off and if crash occurred on a non-boot cpu.
o Issue here is that MP tables report boot cpu lapic id as 0 but second
kernel is booting on a different processor and MP table data is stale
in this context. Hence apic_id_registered() check fails in setup_local_APIC()
when called from APIC_init_uniprocessor().
o Problem is not seen if ACPI is enabled as in that case
boot_cpu_physical_apicid is read from the LAPIC.
o Problem is not seen with SMP kernels as well because in this case also
boot_cpu_physical_apicid is read from LAPIC. (smp_boot_cpus()).
o The problem is fixed by reading boot_cpu_physical_apicid from LAPIC
if it is a UP kernel and CRASH_DUMP is enabled.
