And in cpuset_mems_allowed(), the access to cpuset is under rcu_read_lock, so in __mpol_dup, we can reduce the rcu_read_lock protection region to protect the access to cpuset only in current_cpuset_is_being_rebound(). So that we can avoid this bug. This patch is a temporary solution that just addresses the bug mentioned above, can not fix the long-standing issue about cpuset.mems rebinding on fork(): "When the forker's task_struct is duplicated (which includes ->mems_allowed) and it races with an update to cpuset_being_rebound in update_tasks_nodemask() then the task's mems_allowed doesn't get updated. And the child task's mems_allowed can be wrong if the cpuset's nodemask changes before the child has been added to the cgroup's tasklist." Signed-off-by:

commit d05f0cdc upstream. In v2.6.34 commit 9d8cebd4 ("mm: fix mbind vma merge problem") introduced vma merging to mbind(), but it should have also changed the convention of passing start vma from queue_pages_range() (formerly check_range()) to new_vma_page(): vma merging may have already freed that structure, resulting in BUG at mm/mempolicy.c:1738 and probably worse crashes.

commit 4a705fef upstream. There's a race between fork() and hugepage migration, as a result we try to "dereference" a swap entry as a normal pte, causing kernel panic. The cause of the problem is that copy_hugetlb_page_range() can't handle "swap entry" family (migration entry and hwpoisoned entry) so let's fix it.

commit 84b07386 upstream. When reading from the dispatch trace log (dtl) userspace interface, I sometimes see duplicate entries.

commit 8f21bd00 upstream. The csum_partial_copy_generic() function saves the PowerPC non-volatile r14, r15, and r16 registers for the main checksum-and-copy loop. Unfortunately, it fails to restore them upon error exit from this loop, which results in silent corruption of these registers in the presumably rare event of an access exception within that loop. This commit therefore restores these register on error exit from the loop. Signed-off-by:

commit f5f6cbb6 upstream. /proc/powerpc/lparcfg is an ancient facility (though still actively used) which allows access to some informations relative to the partition when running underneath a PAPR compliant hypervisor. It makes no sense on non-pseries machines. However, currently, not only can it be created on these if the kernel has pseries support, but accessing it on such a machine will crash due to trying to do hypervisor calls. In fact, it should also not do HV calls on older pseries that didn't have an hypervisor either. Finally, it has the plumbing to be a module but is a "bool" Kconfig option. This fixes the whole lot by turning it into a machine_device_initcall that is only created on pseries, and adding the necessary hypervisor check before calling the H_GET_EM_PARMS hypercall Signed-off-by:

commit bf593907 upstream. Normally, the kernel emulates a few instructions that are unimplemented on some processors (e.g. the old dcba instruction), or privileged (e.g. mfpvr). The emulation of unimplemented instructions is currently not working on the PowerNV platform. The reason is that on these machines, unimplemented and illegal instructions cause a hypervisor emulation assist interrupt, rather than a program interrupt as on older CPUs. Our vector for the emulation assist interrupt just calls program_check_exception() directly, without setting the bit in SRR1 that indicates an illegal instruction interrupt. This fixes it by making the emulation assist interrupt set that bit before calling program_check_interrupt(). With this, old programs that use no-longer implemented instructions such as dcba now work again. Signed-off-by:

commit 4b18f08b upstream. `do_cmd_ioctl()` is called with the comedi device's mutex locked to process the `COMEDI_CMD` ioctl to set up comedi's asynchronous command handling on a comedi subdevice. `comedi_read()` and `comedi_write()` are the `read` and `write` handlers for the comedi device, but do not lock the mutex (for performance reasons, as some things can hold the mutex for quite a long time). There is a race condition if `comedi_read()` or `comedi_write()` is running at the same time and for the same file object and comedi subdevice as `do_cmd_ioctl()`. `do_cmd_ioctl()` sets the subdevice's `busy` pointer to the file object way before it sets the `SRF_RUNNING` flag in the subdevice's `runflags` member. `comedi_read() and `comedi_write()` check the subdevice's `busy` pointer is pointing to the current file object, then if the `SRF_RUNNING` flag is not set, will call `do_become_nonbusy()` to shut down the asyncronous command. Bad things can happen if the asynchronous command is being shutdown and set up at the same time. To prevent the race, don't set the `busy` pointer until after the `SRF_RUNNING` flag has been set. Also, make sure the mutex is held in `comedi_read()` and `comedi_write()` while calling `do_become_nonbusy()` in order to avoid moving the race condition to a point within that function. Change some error handling `goto cleanup` statements in `do_cmd_ioctl()` to simple `return -ERRFOO` statements as a result of changing when the `busy` pointer is set. Signed-off-by:

commit e6391a18 upstream. The element of `das08_boards[]` for the 'das08jr-16-ao' board has the `ai_encoding` member set to `das08_encode12`. It should be set to `das08_encode16` same as the 'das08jr/16' board. After all, this board has 16-bit AI resolution. The description of the A/D LSB register at offset 0 seems incorrect in the user manual "cio-das08jr-16-ao.pdf" as it implies that the AI resolution is only 12 bits. The diagrams of the A/D LSB and MSB registers show 15 data bits and a sign bit, which matches what the software expects for the `das08_encode16` AI encoding method. Signed-off-by:

commit fd1232b2 upstream. This patch fixes I/O errors with the sym53c8xx_2 driver when the disk returns QUEUE FULL status. When the controller encounters an error (including QUEUE FULL or BUSY status), it aborts all not yet submitted requests in the function sym_dequeue_from_squeue. This function aborts them with DID_SOFT_ERROR. If the disk has full tag queue, the request that caused the overflow is aborted with QUEUE FULL status (and the scsi midlayer properly retries it until it is accepted by the disk), but the sym53c8xx_2 driver aborts the following requests with DID_SOFT_ERROR --- for them, the midlayer does just a few retries and then signals the error up to sd. The result is that disk returning QUEUE FULL causes request failures. The error was reproduced on 53c895 with COMPAQ BD03685A24 disk (rebranded ST336607LC) with command queue 48 or 64 tags. The disk has 64 tags, but under some access patterns it return QUEUE FULL when there are less than 64 pending tags. The SCSI specification allows returning QUEUE FULL anytime and it is up to the host to retry. Signed-off-by:

commit 133d4527 upstream. When we write to a degraded array which has a bitmap, we make sure the relevant bit in the bitmap remains set when the write completes (so a 're-add' can quickly rebuilt a temporarily-missing device). If, immediately after such a write starts, we incorporate a spare, commence recovery, and skip over the region where the write is happening (because the 'needs recovery' flag isn't set yet), then that write will not get to the new device. Once the recovery finishes the new device will be trusted, but will have incorrect data, leading to possible corruption. We cannot set the 'needs recovery' flag when we start the write as we do not know easily if the write will be "degraded" or not. That depends on details of the particular raid level and particular write request. This patch fixes a corruption issue of long standing and so it suitable for any -stable kernel. It applied correctly to 3.0 at least and will minor editing to earlier kernels. Reported-by:

commit 76f47128 upstream. An NFS operation that creates a new symlink includes the symlink data, which is xdr-encoded as a length followed by the data plus 0 to 3 bytes of zero-padding as required to reach a 4-byte boundary. The vfs, on the other hand, wants null-terminated data. The simple way to handle this would be by copying the data into a newly allocated buffer with space for the final null. The current nfsd_symlink code tries to be more clever by skipping that step in the (likely) case where the byte following the string is already 0. But that assumes that the byte following the string is ours to look at. In fact, it might be the first byte of a page that we can't read, or of some object that another task might modify. Worse, the NFSv4 code tries to fix the problem by actually writing to that byte. In the NFSv2/v3 cases this actually appears to be safe: - nfs3svc_decode_symlinkargs explicitly null-terminates the data (after first checking its length and copying it to a new page). - NFSv2 limits symlinks to 1k. The buffer holding the rpc request is always at least a page, and the link data (and previous fields) have maximum lengths that prevent the request from reaching the end of a page. In the NFSv4 case the CREATE op is potentially just one part of a long compound so can end up on the end of a page if you're unlucky. The minimal fix here is to copy and null-terminate in the NFSv4 case. The nfsd_symlink() interface here seems too fragile, though. It should really either do the copy itself every time or just require a null-terminated string. Reported-by:

commit c021f241 upstream. Fix a parser-bug in the omap2 muxing code where muxtable-entries will be wrongly selected if the requested muxname is a *prefix* of their m0-entry and they have a matching mN-entry. Fix by additionally checking that the length of the m0_entry is equal. For example muxing of "dss_data2.dss_data2" on omap32xx will fail because the prefix "dss_data2" will match the mux-entries "dss_data2" as well as "dss_data20", with the suffix "dss_data2" matching m0 (for dss_data2) and m4 (for dss_data20). Thus both are recognized as signal path candidates: Relevant muxentries from mux34xx.c: _OMAP3_MUXENTRY(DSS_DATA20, 90, "dss_data20", NULL, "mcspi3_somi", "dss_data2", "gpio_90", NULL, NULL, "safe_mode"), _OMAP3_MUXENTRY(DSS_DATA2, 72, "dss_data2", NULL, NULL, NULL, "gpio_72", NULL, NULL, "safe_mode"), This will result in a failure to mux the pin at all: _omap_mux_get_by_name: Multiple signal paths (2) for dss_data2.dss_data2 Patch should apply to linus' latest master down to rather old linux-2.6 trees.

commit e10b9969 upstream. In this API, we were using sizeof operator for an array given as function argument, which is invalid. However this API is not used anywhere. Signed-off-by:

commit ba15a58b upstream. From the Bluetooth Core Specification 4.1 page 1958: "if both devices have set the Authentication_Requirements parameter to one of the MITM Protection Not Required options, authentication stage 1 shall function as if both devices set their IO capabilities to DisplayOnly (e.g., Numeric comparison with automatic confirmation on both devices)" So far our implementation has done user confirmation for all just-works cases regardless of the MITM requirements, however following the specification to the word means that we should not be doing confirmation when neither side has the MITM flag set.

commit 4e578080 upstream. Commit "drm/vmwgfx: correct fb_fix_screeninfo.line_length", while fixing a vmwgfx fbdev bug, also writes the pitch to a supposedly read-only register: SVGA_REG_BYTES_PER_LINE, while it should be (and also in fact is) written to SVGA_REG_PITCHLOCK. This patch is Cc'd stable because of the unknown effects writing to this register might have, particularly on older device versions. v2: Updated log message.
