2011-05-04slub: Fix the lockless code on 32-bit platforms with no 64-bit cmpxchgThomas Gleixner2-3/+3
The SLUB allocator use of the cmpxchg_double logic was wrong: it actually needs the irq-safe one. That happens automatically when we use the native unlocked 'cmpxchg8b' instruction, but when compiling the kernel for older x86 CPUs that do not support that instruction, we fall back to the generic emulation code. And if you don't specify that you want the irq-safe version, the generic code ends up just open-coding the cmpxchg8b equivalent without any protection against interrupts or preemption. Which definitely doesn't work for SLUB. This was reported by Werner Landgraf <[email protected]>, who saw instability with his distro-kernel that was compiled to support pretty much everything under the sun. Most big Linux distributions tend to compile for PPro and later, and would never have noticed this problem. This also fixes the prototypes for the irqsafe cmpxchg_double functions to use 'bool' like they should. [ Btw, that whole "generic code defaults to no protection" design just sounds stupid - if the code needs no protection, there is no reason to use "cmpxchg_double" to begin with. So we should probably just remove the unprotected version entirely as pointless. - Linus ] Signed-off-by: Thomas Gleixner <[email protected]> Reported-and-tested-by: werner <[email protected]> Acked-and-tested-by: Ingo Molnar <[email protected]> Acked-by: Christoph Lameter <[email protected]> Cc: Pekka Enberg <[email protected]> Cc: Jens Axboe <[email protected]> Cc: Tejun Heo <[email protected]> Link: http://lkml.kernel.org/r/alpine.LFD.2.02.1105041539050.3005@ionos Signed-off-by: Ingo Molnar <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2011-05-03logfs: initialize superblock entries earlierLinus Torvalds1-4/+4
In particular, s_freeing_list needs to be initialized early, since it is used on some of the error paths when mounts fail. The mapping inode, for example, would be initialized and then free'd on an error path before s_freeing_list was initialized, but the inode drop operation needs the s_freeing_list to be set up. Normally you'd never see this, because not only is logfs fairly rare, but a successful mount will never have any issues.

2011-05-02firewire: Fix for broken configrom updates in quick successionB.J. Buchalter1-14/+25
Current implementation of ohci_set_config_rom() uses a deferred bus reset via fw_schedule_bus_reset(). If clients add multiple unit descriptors to the config_rom in quick succession, the deferred bus reset may not have fired before succeeding update requests have come in. This can lead to an incorrect partial update of the config_rom for both addition and removal of config_rom descriptors, as the ohci_set_config_rom() routine will return -EBUSY if a previous pending update has not been completed yet; the requested update just gets dropped on the floor. This patch recognizes that the "in-flight" update can be modified until it has been processed by the bus-reset, and the locking in the bus_reset_tasklet ensures that the update is done atomically with respect to modifications made by ohci_set_config_rom(). The -EBUSY error case is simply removed. [Stefan R: The bug always existed at least theoretically. But it became easy to trigger since 2.6.36 commit 02d37bed188c "firewire: core: integrate software-forced bus resets with bus management" which introduced long mandatory delays between janitorial bus resets.] Signed-off-by: Benjamin Buchalter <[email protected]> Signed-off-by: Stefan Richter <[email protected]> (trivial style changes) Cc: <[email protected]> # 2.6.36.y and newer

As a consequence of the commit: commit 4b239f458c229de044d6905c2b0f9fe16ed9e01e Author: Yinghai Lu <[email protected]> Date: Fri Dec 17 16:58:28 2010 -0800 x86-64, mm: Put early page table high it causes the Linux kernel to crash under Xen: mapping kernel into physical memory Xen: setup ISA identity maps about to get started...

The reason is that at some point init_memory_mapping is going to reach the pagetable pages area and map those pages too (mapping them as normal memory that falls in the range of addresses passed to init_memory_mapping as argument). Some of those pages are already pagetable pages (they are in the range pgt_buf_start-pgt_buf_end) therefore they are going to be mapped RO and everything is fine. Some of these pages are not pagetable pages yet (they fall in the range pgt_buf_end-pgt_buf_top; for example the page at pgt_buf_end) so they are going to be mapped RW. When these pages become pagetable pages and are hooked into the pagetable, xen will find that the guest has already a RW mapping of them somewhere and fail the operation. The reason Xen requires pagetables to be RO is that the hypervisor needs to verify that the pagetables are valid before using them. The validation operations are called "pinning" (more details in arch/x86/xen/mmu.c). In order to fix the issue we mark all the pages in the entire range pgt_buf_start-pgt_buf_top as RO, however when the pagetable allocation is completed only the range pgt_buf_start-pgt_buf_end is reserved by init_memory_mapping. Hence the kernel is going to crash as soon as one of the pages in the range pgt_buf_end-pgt_buf_top is reused (b/c those ranges are RO). For this reason, this function is introduced which is called _after_ the init_memory_mapping has completed (in a perfect world we would call this function from init_memory_mapping, but lets ignore that). Because we are called _after_ init_memory_mapping the pgt_buf_[start, end,top] have all changed to new values (b/c another init_memory_mapping is called). Hence, the first time we enter this function, we save away the pgt_buf_start value and update the pgt_buf_[end,top]. When we detect that the "old" pgt_buf_start through pgt_buf_end PFNs have been reserved (so memblock_x86_reserve_range has been called), we immediately set out to RW the "old" pgt_buf_end through pgt_buf_top. And then we update those "old" pgt_buf_[end|top] with the new ones so that we can redo this on the next pagetable. Acked-by: "H.

2011-05-02genirq: Fix typo CONFIG_GENIRC_IRQ_SHOW_LEVELGeert Uytterhoeven1-1/+1
commit ab7798ffcf98b11a9525cf65bacdae3fd58d357f ("genirq: Expand generic show_interrupts()") added the Kconfig option GENERIC_IRQ_SHOW_LEVEL to accomodate PowerPC, but this doesn't actually enable the functionality due to a typo in the #ifdef check.

2011-05-02UBIFS: seek journal heads to the latest bud in replayArtem Bityutskiy1-6/+12
This is the second fix of the following symptom: UBIFS error (pid 34456): could not find an empty LEB which sometimes happens after power cuts when we mount the file-system - UBIFS refuses it with the above error message which comes from the 'ubifs_rcvry_gc_commit()' function. I can reproduce this using the integck test with the UBIFS power cut emulation enabled. Analysis of the problem. Currently UBIFS replay seeks the journal heads to the last _replayed_ bud. But the buds are replayed out-of-order, so the replay basically seeks journal heads to the "random" bud belonging to this head, and not to the _last_ one. The result of this is that the GC head may be seeked to a full LEB with no free space, or very little free space. And 'ubifs_rcvry_gc_commit()' tries to find a fully or mostly dirty LEB to match the current GC head (because we need to garbage-collect that dirty LEB at one go, because we do not have @c->gc_lnum). So 'ubifs_find_dirty_leb()' fails and we fall back to finding an empty LEB and also fail. As a result - recovery fails and mounting fails. This patch teaches the replay to initialize the GC heads exactly to the latest buds, i.e. the buds which have the largest sequence number in corresponding log reference nodes.
