2006-05-23[PATCH] blk: fix gendisk->in_flight accounting during barrier sequenceJens Axboe1-1/+6
While executing barrrier sequence, the bar_rq which carries actual write was accounted as normal IO on completion, while it wasn't on queueing. This caused gendisk->in_flight to be decremented by 1 after each barrier thus messed up statistics. This patch makes bar_rq not accounted as normal IO. As the containing barrier request as a whole is accounted, part of it shouldn't be.

2006-05-23[PATCH] md: fix possible oops when starting a raid0 arrayNeilBrown1-2/+3
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.

2006-05-23[SPARC64]: Respect gfp_t argument to dma_alloc_coherent().David S. Miller4-7/+146
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 routines and (correctly) expects that to work. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-05-22[NETFILTER]: SNMP NAT: fix memory corruptionPatrick McHardy1-8/+7
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. Found by multiple testcases of the trap-app and trap-enc groups of the PROTOS c06-snmpv1 testsuite. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2006-05-21[PATCH] Align the node_mem_map endpoints to a MAX_ORDER boundaryBob Picco2-3/+12
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.

2006-05-21[PATCH] Fix a NO_IDLE_HZ timer bugZachary Amsden1-0/+16
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).

2006-05-21[PATCH] kprobes: bad manipulation of 2 byte opcode on x86_64Satoshi Oshima1-3/+3
Problem: 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 little bit different from x86_64.

2006-05-21[PATCH] i386 kdump boot cpu physical apicid fixVivek Goyal1-0/+8
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.

2006-05-21[PATCH] pxa2xx-spi updateStephen Street2-37/+59
Fix some outstanding issues with the pxa2xx_spi driver when running on a PXA270: - Wrong timeout calculation in the setup function due to different peripheral clock rates in the PXAxxx family. - Bad handling of SSSR_TFS interrupts in interrupt_transfer function. - Added locking to interface between the pump_messages workqueue and the pump_transfers tasklet. Much thanks to Juergen Beisert for the extensive testing on the PXA270.

2006-05-21[PATCH] spi: add spi master driver for Freescale MPC83xx SPI controllerKumar Gala4-0/+507
This driver supports the SPI controller on the MPC83xx SoC devices from Freescale. Note, this driver supports only the simple shift register SPI controller and not the descriptor based CPM or QUICCEngine SPI controller.
