commit e51ee31e upstream. Michael Ellerman reported stack-frame size warnings being produced for power_check_constraints(), which uses an 8*8 array of u64 and two 8*8 arrays of unsigned long, which are currently allocated on the stack, along with some other smaller variables. These arrays come to 1.5kB on 64-bit or 1kB on 32-bit, which is a bit too much for the stack. This fixes the problem by putting these arrays in the existing per-cpu cpu_hw_counters struct. This is OK because two of the call sites have interrupts disabled already; for the third call site we use get_cpu_var, which disables preemption, so we know we won't get a context switch while we're in power_check_constraints(). Note that power_check_constraints() can be called during context switch but is not called from interrupts. Reported-by:

commit fa289bec upstream. Currently, if a group is created where the group leader is initially disabled but a non-leader member is initially enabled, and then the leader is subsequently enabled some time later, the time_enabled for the non-leader member will reflect the whole time since it was created, not just the time since the leader was enabled. This is incorrect, because all of the members are effectively disabled while the leader is disabled, since none of the members can go on the PMU if the leader can't. Thus we have to update the ->tstamp_enabled for all the enabled group members when a group leader is enabled, so that the time_enabled computation only counts the time since the leader was enabled. Similarly, when disabling a group leader we have to update the time_enabled and time_running for all of the group members. Also, in update_counter_times, we have to treat a counter whose group leader is disabled as being disabled. Reported-by:

commit b3e62e35 upstream. If we pass a big size data over perf_counter_open() syscall, the kernel will copy this data to a small buffer, it will cause kernel crash. This bug makes the kernel unsafe and non-root local user can trigger it. Signed-off-by:

commit 2195d281 upstream. My 353d5c30 "mm: fix hugetlb bug due to user_shm_unlock call" broke the CONFIG_SYSVIPC !CONFIG_MMU build of both 2.6.31 and 2.6.30.6: "undefined reference to `user_shm_unlock'". gcc didn't understand my comment! so couldn't figure out to optimize away user_shm_unlock() from the error path in the hugetlb-less case, as it does elsewhere. Help it to do so, in a language it understands. Reported-by:

commit 0d03d59d upstream. Commit b8313b6d ("dm log: remove incorrect field from userspace table output") added a call to strstr() with a single-character "needle" string parameter. Unfortunately some versions of gcc replace such calls to strstr() by calls to strchr() behind our back. This causes linking errors if strchr() is defined as an inline function in <asm/string.h> (e.g. on m68k): | WARNING: "strchr" [drivers/md/dm-log-userspace.ko] undefined! Avoid this by explicitly calling strchr() instead. Signed-off-by:

commit ec579358 upstream. When probing the device in tpm_tis_init the call request_locality uses timeout_a, which wasn't being initalized until after request_locality. This results in request_locality falsely timing out if the chip is still starting. Move the initialization to before request_locality. This probably only matters for embedded cases (ie mine), a BIOS likely gets the TPM into a state where this code path isn't necessary. Signed-off-by:

commit 9f0ab4a3 upstream. In fs/binfmt_elf.c, load_elf_interp() calls padzero() for .bss even if the PT_LOAD has no PROT_WRITE and no .bss. This generates EFAULT. Here is a small test case. (Yes, there are other, useful PT_INTERP which have only .text and no .data/.bss.) ----- ptinterp.S _start: .globl _start nop int3 ----- $ gcc -m32 -nostartfiles -nostdlib -o ptinterp ptinterp.S $ gcc -m32 -Wl,--dynamic-linker=ptinterp -o hello hello.c $ ./hello Segmentation fault # during execve() itself After applying the patch: $ ./hello Trace trap # user-mode execution after execve() finishes If the ELF headers are actually self-inconsistent, then dying is fine. But having no PROT_WRITE segment is perfectly normal and correct if there is no segment with p_memsz > p_filesz (i.e. bss). John Reiser suggested checking for PROT_WRITE in the bss logic. I think it makes most sense to simply apply the bss logic only when there is bss. This patch looks less trivial than it is due to some reindentation. It just moves the "if (last_bss > elf_bss) {" test up to include the partial-page bss logic as well as the more-pages bss logic. Reported-by:

commit fcc6cb0c upstream. The find_ie() function uses a size_t for the len parameter, and directly uses len as a loop variable. If any received packets are malformed, it is possible for the decrease of len to overflow, and since the result is unsigned, the loop will not terminate. Change it to a signed int so the loop conditional works for negative values. This fixes the following soft lockup: [38573.102007] BUG: soft lockup - CPU#0 stuck for 61s!

commit afffd3da upstream. This patch fixes a memory leak in the libsrp function srp_ring_free(). It is not documented whether or not this function should free the ring pointer itself. But the source code of the callers of this function (srp_target_alloc() and srp_target_free()) makes it clear that srp_ring_free() should deallocate the ring pointer itself. Furthermore, the patch below makes srp_ring_free() deallocate all memory allocated by srp_ring_alloc(). This patch affects the ibmvstgt driver, which is the only in-tree driver that calls the srp_ring_free() function (indirectly). Signed-off-by:

Fix this by taking a reference before starting the thread and dropping it again when the thread completes. Reported-by:

commit ed79f128 upstream. This patch modifies the slave_configure callback so the messages that get sent to system log for RAID1E volumes contain the string "RAID10" instead of "RAID1E". These messages contain information regarding what kind of scsi device is being added. Certain OEMS can enable displaying the RAID10 string instead of RAID1E via manufacturing page 10. The driver will read this config page at driver load time, then determine from the GenericFlags0 bits whether display the RAID10 or RAID1E string, also even drive count is taken into consideration.

commit 34a03bef upstream. Changing SDEV Running state from interrupt context. Previously It was handle in work queue thread. With this change It will not wait for work queue thread to execute scsih_ublock_io_device to put SDEV into Running state. This will reduce delay for Device becoming RUNNING. Modified this patch considering James comment "Not to change SDEV state using scsi_device_set_state API, instead use scsi_internal_device_unblock scsi_internal_device_block API" Signed-off-by:

commit 155dd4c7 upstream. This patch renames the flag for indicating host reset from ioc_reset_in_progress to shost_recovery. It also removes the spin locks surrounding the setting of this flag, which are unnecessary. Sanity checks on the shost_recovery flag were added thru out the code so as to prevent sending firmware commands during host reset. Also, the setting of the shost state to SHOST_RECOVERY was removed to prevent deadlocks, this is actually better handled by the shost_recovery flag. Signed-off-by:

commit cd4e12e8 upstream. Following host reset its possible that the controller firmware could assign new handles for devices, as well as adding or deleting devices. There is code in the driver that will rescan the topology folowing host reset; updating device handles, and remove devices that are no longer responding. This patch will improve the responsivness by moving this rescaning from the delayed hotplug worker thread to immediately following the host reset. Signed-off-by:

Andy Whitcroft reported an oops in aoe triggered by use of an incorrectly initialised request_queue object: [ 2645.959090] kobject '<NULL>' (ffff880059ca22c0): tried to add an uninitialized object, something is seriously wrong. [ 2645.959104] Pid: 6, comm: events/0 Not tainted 2.6.31-5-generic #24-Ubuntu [ 2645.959107] Call Trace: [ 2645.959139] [<ffffffff8126ca2f>] kobject_add+0x5f/0x70 [ 2645.959151] [<ffffffff8125b4ab>] blk_register_queue+0x8b/0xf0 [ 2645.959155] [<ffffffff8126043f>] add_disk+0x8f/0x160 [ 2645.959161] [<ffffffffa01673c4>] aoeblk_gdalloc+0x164/0x1c0 [aoe] The request queue of an aoe device is not used but can be allocated in code that does not sleep. Bruno bisected this regression down to cd43e26f block: Expose stacked device queues in sysfs "This seems to generate /sys/block/$device/queue and its contents for everyone who is using queues, not just for those queues that have a non-NULL queue->request_fn." Addresses http://bugs.launchpad.net/bugs/410198 Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13942 Note that embedding a queue inside another object has always been an illegal construct, since the queues are reference counted and must persist until the last reference is dropped. So aoe was always buggy in this respect (Jens). Signed-off-by:

Reinette Chatre reports a frozen system (with blinking keyboard LEDs) when switching from graphics mode to the text console, or when suspending (which does the same thing). With netconsole, the oops turned out to be BUG: unable to handle kernel NULL pointer dereference at 0000000000000084 IP: [<ffffffffa03ecaab>] i915_driver_irq_handler+0x26b/0xd20 [i915] and it's due to the i915_gem.c code doing drm_irq_uninstall() after having done i915_gem_idle(). And the i915_gem_idle() path will do i915_gem_idle() -> i915_gem_cleanup_ringbuffer() -> i915_gem_cleanup_hws() -> dev_priv->hw_status_page = NULL; but if an i915 interrupt comes in after this stage, it may want to access that hw_status_page, and gets the above NULL pointer dereference. And since the NULL pointer dereference happens from within an interrupt, and with the screen still in graphics mode, the common end result is simply a silently hung machine. Fix it by simply uninstalling the irq handler before idling rather than after.

This adds some rv350+ register for LTE/GTE discard, and enables the rv515 two sided stencil register. It also disables the DEPTHXY_OFFSET register which can be used to workaround the CS checker. Moves rs690 to proper place in rs600 and uses correct table on rs600. Signed-off-by:Dave Airlie <airlied@redhat.com>

- As ima_counts_put() may be called after the inode has been freed, verify that the inode is not NULL, before dereferencing it. - Maintain the IMA file counters in may_open() properly, decrementing any counter increments on subsequent errors. Reported-by:

Reported by Michael Guntsche <mike@it-loops.com> -------------------- Commit 38bddf04 gianfar: gfar_remove needs to call unregister_netdev() breaks the build of the gianfar driver because "dev" is undefined in this function. To quickly test rc9 I changed this to priv->ndev but I do not know if this is the correct one. -------------------- Signed-off-by:

This patch fixes a null pointer exception caused by removal of 'ack()' for level interrupts in the Xilinx interrupt driver. A recent change to the xilinx interrupt controller removed the ack hook for level irqs. Signed-off-by:
