This moves it to being a tty operation. That removes special cases and now also means that resize can be picked up by um and other non vt consoles which may have a resize operation. Signed-off-by:

A fuzzed fileystem image failed with OMFS when the extent count was used in a loop without being checked against the max number of extents. It also provoked a signed division for an array index that was checked as if unsigned, leading to index by -1. omfsck will be updated to fix these cases, in the meantime bail out gracefully.

Testing with a modified fsfuzzer reveals a couple of locations in omfs where filesystem variables are ultimately used as loop counters with insufficient sanity checking. In this case, dir->i_size is used to compute the number of buckets in the directory hash. If too large, readdir will overrun a buffer. Since it's an invariant that dir->i_size is equal to the sysblock size, and we already sanity check that, just use that value instead. This fixes the following oops: BUG: unable to handle kernel paging request at c978e004 IP: [<c032298e>] omfs_readdir+0x18e/0x32f Oops: 0000 [#1] PREEMPT DEBUG_PAGEALLOC Modules linked in: Pid: 4796, comm: ls Not tainted (2.6.27-rc2 #12) EIP: 0060:[<c032298e>] EFLAGS: 00010287 CPU: 0 EIP is at omfs_readdir+0x18e/0x32f EAX: c978d000 EBX: 00000000 ECX: cbfcfaf8 EDX: cb2cf100 ESI: 00001000 EDI: 00000800 EBP: cb2d3f68 ESP: cb2d3f0c DS: 007b ES: 007b FS: 0000 GS: 0033 SS: 0068 Process ls (pid: 4796, ti=cb2d3000 task=cb175f40 task.ti=cb2d3000) Stack: 00000002 00000000 00000000 c018a820 cb2d3f94 cb2cf100 cbfb0000 ffffff10 cbfb3b80 cbfcfaf8 000001c9 00000a09 00000000 00000000 00000000 cbfcfbc8 c9697000 cbfb3b80 22222222 00001000 c08e6cd0 cb2cf100 cbfb3b80 cb2d3f88 Call Trace: [<c018a820>] ? filldir64+0x0/0xcd [<c018a9f2>] ? vfs_readdir+0x56/0x82 [<c018a820>] ? filldir64+0x0/0xcd [<c018aa7c>] ? sys_getdents64+0x5e/0xa0 [<c01038bd>] ? sysenter_do_call+0x12/0x31 ======================= Code: 00 89 f0 89 f3 0f ac f8 14 81 e3 ff ff 0f 00 48 8d 14 c5 b8 01 00 00 89 45 cc 89 55 f0 e9 8c 01 00 00 8b 4d c8 8b 75 f0 8b 41 18 <8b> 54 30 04 8b 04 30 31 f6 89 5d dc 89 d1 8b 55 b8 0f c8 0f c9 Reported-by: -

When reviewing a recent patch I noticed a potential trouble spot in the registration of new SPI devices. The SPI master driver is told to set the device up before adding it to the driver model, so that it's always properly set up when probe() is called. (This is important, because in the case of inverted chipselects, this device can make the bus misbehave until it's properly deselected. It's got to be set up even if no driver binds to the device.) The trouble spot is that it doesn't first verify that no other device has been added using that chipselect. If such a device has been added, its configuration gets trashed. (Fortunately this has not been a common error!) The fix here adds an explicit check, and a mutex to protect the relevant critical region.

write_cache_pages() uses i_mapping->writeback_index to pick up where it left off the last time a given inode was found by pdflush or balance_dirty_pages (or anyone else who sets wbc->range_cyclic) alloc_inode() should set it to a sane value so that writeback doesn't start in the middle of a file. It is somewhat difficult to notice the bug since write_cache_pages will loop around to the start of the file and the elevator helps hide the resulting seeks. For whatever reason, Btrfs hits this often. Unpatched, untarring 30 copies of the linux kernel in series runs at 47MB/s on a single sata drive. With this fix, it jumps to 62MB/s. Signed-off-by:

Currently, all sensors are read when the energy meter is queried via sysfs. This introduces a considerable amount of delay and variation in the sysfs reading, which is not desirable when trying to profile energy use. Therefore, read only the energy meters when a sysfs query comes in for them, and don't cache the results so that we always get the latest reading. Signed-off-by:

On older machines, probing for a nonexistent AEM interface returned an IPMI error; when we saw this, we'd stop probing. On the x3650 M2 and (presumably) later, we are returned a value indicating success and a buffer full of garbage or zeroes. This causes the probe function to run in an infinite loop. To fix this, we add one last check--if the interface number we're looking for is higher than the number of interfaces that AEM claims to have, stop probing. Signed-off-by:

Previously the driver was only using DMI to prevent smbus probing on non-Abit motherboards. However, since the manual probing method is brittle and prone to failure on some Abit motherboards (esp. the Abit IP35 Pro) it is better to use DMI to also read the board name and then decide whether or not to probe the bus. At the moment, we do not have a list of valid DMI name strings to use for existing and supported motherboards. This patch only implements DMI probing for the IP35 Pro. For motherboards that can not yet use DMI probing, a warning will be printed to the kernel log asking those users to email me their dmidecode output. The existing manual probing mechanism will be used if CONFIG_DMI is not enabled, if DMI probing fails (for DMI-unsupported motherboards), or if DMI probing fails and the "force" option is set (for DMI-supported motherboards). Ideally in the longer term this manual probing method would be removed. This patch should be safe to apply as it does not change the probing behaviour for most of the supported motherboards, just the IP35 Pro, which already has regressions filed against it in 2.6.26.

This is the minimal sequence that jams the allocator: void *p, *q, *r; p = alloc_bootmem(PAGE_SIZE); q = alloc_bootmem(64); free_bootmem(p, PAGE_SIZE); p = alloc_bootmem(PAGE_SIZE); r = alloc_bootmem(64); after this sequence (assuming that the allocator was empty or page-aligned before), pointer "q" will be equal to pointer "r". What's hapenning inside the allocator: p = alloc_bootmem(PAGE_SIZE); in allocator: last_end_off == PAGE_SIZE, bitmap contains bits 10000... q = alloc_bootmem(64); in allocator: last_end_off == PAGE_SIZE + 64, bitmap contains 11000... free_bootmem(p, PAGE_SIZE); in allocator: last_end_off == PAGE_SIZE + 64, bitmap contains 01000... p = alloc_bootmem(PAGE_SIZE); in allocator: last_end_off == PAGE_SIZE, bitmap contains 11000... r = alloc_bootmem(64); and now: it finds bit "2", as a place where to allocate (sidx) it hits the condition if (bdata->last_end_off && PFN_DOWN(bdata->last_end_off) + 1 == sidx)) start_off = ALIGN(bdata->last_end_off, align); -you can see that the condition is true, so it assigns start_off = ALIGN(bdata->last_end_off, align); (that is PAGE_SIZE) and allocates over already allocated block. With the patch it tries to continue at the end of previous allocation only if the previous allocation ended in the middle of the page. Signed-off-by:

acpi_penalize_isa_irq() should validate irq before using it to index the acpi_irq_penalty[] table. Here's the path I'm concerned about: pnpacpi_parse_allocated_irqresource() { ... irq = acpi_register_gsi(gsi, triggering, polarity); if (irq >= 0) pcibios_penalize_isa_irq(irq, 1); There's no guarantee that acpi_register_gsi() will return an IRQ within the bounds of acpi_irq_penalty[]. I have not seen a failure I can attribute to this. However, ACPI_MAX_IRQS is only 256, and I'm pretty sure ia64 can have IRQs larger than that. I think this should go in 2.6.27.
