I found that the modules for the network was not being installed. This was due to the config CONFIG_MODULES_USE_ELF_RELA that came before CONFIG_MODULES, and confused ktest in thinking that CONFIG_MODULES=y was not found. Ktest needs to test all configs and not just stop if something starts with CONFIG_MODULES." * tag 'ktest-v3.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest: ktest: Fix ktest confusion with CONFIG_MODULES_USE_ELF_RELA 28 October 2012, 18:14:52 UTC

1a25b1c Mikulas Patocka 15 October 2012, 21:20:17 UTC Lock splice_read and splice_write functions Functions generic_file_splice_read and generic_file_splice_write access the pagecache directly. For block devices these functions must be locked so that block size is not changed while they are in progress. This patch is an additional fix for commit b87570f5d349 ("Fix a crash when block device is read and block size is changed at the same time") that locked aio_read, aio_write and mmap against block size change.

1bf11c5 Mikulas Patocka 22 October 2012, 23:39:16 UTC percpu-rw-semaphores: use rcu_read_lock_sched Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu. This is an optimization. The RCU-protected region is very small, so there will be no latency problems if we disable preempt in this region. So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates to preempt_disable / preempt_disable. It is smaller (and supposedly faster) than preemptible rcu_read_lock / rcu_read_unlock.

5c1eabe Mikulas Patocka 22 October 2012, 23:37:47 UTC percpu-rw-semaphores: use light/heavy barriers This patch introduces new barrier pair light_mb() and heavy_mb() for percpu rw semaphores. This patch fixes a bug in percpu-rw-semaphores where a barrier was missing in percpu_up_write. This patch improves performance on the read path of percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in percpu_up_read. This patch changes it to a compiler barrier and removes the "#if defined(X86) ..." condition.

561ec64 Linus Torvalds 26 October 2012, 17:05:07 UTC VFS: don't do protected {sym,hard}links by default In commit 800179c9b8a1 ("This adds symlink and hardlink restrictions to the Linux VFS"), the new link protections were enabled by default, in the hope that no actual application would care, despite it being technically against legacy UNIX (and documented POSIX) behavior. However, it does turn out to break some applications. It's rare, and it's unfortunate, but it's unacceptable to break existing systems, so we'll have to default to legacy behavior. In particular, it has broken the way AFD distributes files, see http://www.dwd.de/AFD/ along with some legacy scripts. Distributions can end up setting this at initrd time or in system scripts: if you have security problems due to link attacks during your early boot sequence, you have bigger problems than some kernel sysctl setting. Do: echo 1 > /proc/sys/fs/protected_symlinks echo 1 > /proc/sys/fs/protected_hardlinks to re-enable the link protections. Alternatively, we may at some point introduce a kernel config option that sets these kinds of "more secure but not traditional" behavioural options automatically.

Anchoring urb increments the urb reference count. These deferred urbs are later accessed by calling usb_get_from_anchor() for submission during interface resume. usb_get_from_anchor() unanchors the urb but urb reference count remains same. This causes the urb reference count to remain non-zero after usb_free_urb() gets called and urb never gets freed. Hence call usb_put_urb() after anchoring the urb to properly balance the reference count for these deferred urbs. Also, unanchor these deferred urbs during disconnect, to free them up.

But it also checks if the '=y' part exists. It only will install modules if the config exists and is set with '=y'. But as the regex that was used tests: /^CONFIG_MODULES(=y)?/ this will also match: CONFIG_MODULES_USE_ELF_RELA as the '=y' part was optional and it did not test the rest of the line. When this happens, ktest will stop checking the rest of the configs but it will also think that no modules are needed to be installed. What it should do is only jump out of the loop if it actually found a CONFIG_MODULES that is set to true. Otherwise, ktest wont install the necessary modules needed for proper booting of the test target. Signed-off-by: Steven Rostedt <rostedt@goodmis.org> 26 October 2012, 04:10:32 UTC

Unlike other tablets that report sensor data through separate interfaces of the same USB device, the Cintiq 24HD touch has separate USB devices that are connected to an internal USB hub. This patch makes it possible to designate the USB VID/PID of the other device so that the two may share data. To ensure we don't accidentally link to a sensor from a physically separate device (if several have been plugged in), we limit the search to siblings (i.e., devices directly connected to the same hub).

The default kernel-exported device is called /dev/hwrng not /dev/hwrandom nor /dev/hw_random (both of which were used in the past; however, kernel and udev seem to have converged on /dev/hwrng.)

f230250 Andrew Vagin 25 October 2012, 20:38:07 UTC pidns: limit the nesting depth of pid namespaces 'struct pid' is a "variable sized struct" - a header with an array of upids at the end. The size of the array depends on a level (depth) of pid namespaces. Now a level of pidns is not limited, so 'struct pid' can be more than one page. Looks reasonable, that it should be less than a page. MAX_PIS_NS_LEVEL is not calculated from PAGE_SIZE, because in this case it depends on architectures, config options and it will be reduced, if someone adds a new fields in struct pid or struct upid. I suggest to set MAX_PIS_NS_LEVEL = 32, because it saves ability to expand "struct pid" and it's more than enough for all known for me use-cases. When someone finds a reasonable use case, we can add a config option or a sysctl parameter. In addition it will reduce the effect of another problem, when we have many nested namespaces and the oldest one starts dying. zap_pid_ns_processe will be called for each namespace and find_vpid will be called for each process in a namespace. find_vpid will be called minimum max_level^2 / 2 times. The reason of that is that when we found a bit in pidmap, we can't determine this pidns is top for this process or it isn't. vpid is a heavy operation, so a fork bomb, which create many nested namespace, can make a system inaccessible for a long time. For example my system becomes inaccessible for a few minutes with 4000 processes.

d5ea7b5 Hein Tibosch 25 October 2012, 20:38:05 UTC drivers/dma/dw_dmac: make driver's endianness configurable The dw_dmac driver was originally developed for avr32 to be used with the Synopsys DesignWare AHB DMA controller. Starting from 2.6.38, access to the device's i/o memory was done with the little-endian readl/writel functions(1) This broke the driver for the avr32 platform, because it needs big (native) endian accessors. This patch makes the endianness configurable using 'DW_DMAC_BIG_ENDIAN_IO', which will default be true for AVR32 I submitted this patch before(2) but then waited for Andy to finish other changes to the same module(3).

eedce14 Thadeu Lima de Souza Cascardo 25 October 2012, 20:37:51 UTC genalloc: stop crashing the system when destroying a pool The genalloc code uses the bitmap API from include/linux/bitmap.h and lib/bitmap.c, which is based on long values. Both bitmap_set from lib/bitmap.c and bitmap_set_ll, which is the lockless version from genalloc.c, use BITMAP_LAST_WORD_MASK to set the first bits in a long in the bitmap. That one uses (1 << bits) - 1, 0b111, if you are setting the first three bits. This means that the API counts from the least significant bits (LSB from now on) to the MSB. The LSB in the first long is bit 0, then. The same works for the lookup functions. The genalloc code uses longs for the bitmap, as it should. In include/linux/genalloc.h, struct gen_pool_chunk has unsigned long bits[0] as its last member. When allocating the struct, genalloc should reserve enough space for the bitmap. This should be a proper number of longs that can fit the amount of bits in the bitmap. However, genalloc allocates an integer number of bytes that fit the amount of bits, but may not be an integer amount of longs. 9 bytes, for example, could be allocated for 70 bits. This is a problem in itself if the Least Significat Bit in a long is in the byte with the largest address, which happens in Big Endian machines. This means genalloc is not allocating the byte in which it will try to set or check for a bit. This may end up in memory corruption, where genalloc will try to set the bits it has not allocated. In fact, genalloc may not set these bits because it may find them already set, because they were not zeroed since they were not allocated. And that's what causes a BUG when gen_pool_destroy is called and check for any set bits. What really happens is that genalloc uses kmalloc_node with __GFP_ZERO on gen_pool_add_virt. With SLAB and SLUB, this means the whole slab will be cleared, not only the requested bytes. Since struct gen_pool_chunk has a size that is a multiple of 8, and slab sizes are multiples of 8, we get lucky and allocate and clear the right amount of bytes. Hower, this is not the case with SLOB or with older code that did memset after allocating instead of using __GFP_ZERO. So, a simple module as this (running 3.6.0), will cause a crash when rmmod'ed.

ef5d437 Jan Kara 25 October 2012, 20:37:31 UTC mm: fix XFS oops due to dirty pages without buffers on s390 On s390 any write to a page (even from kernel itself) sets architecture specific page dirty bit. Thus when a page is written to via buffered write, HW dirty bit gets set and when we later map and unmap the page, page_remove_rmap() finds the dirty bit and calls set_page_dirty(). Dirtying of a page which shouldn't be dirty can cause all sorts of problems to filesystems. The bug we observed in practice is that buffers from the page get freed, so when the page gets later marked as dirty and writeback writes it, XFS crashes due to an assertion BUG_ON(!PagePrivate(page)) in page_buffers() called from xfs_count_page_state(). Similar problem can also happen when zero_user_segment() call from xfs_vm_writepage() (or block_write_full_page() for that matter) set the hardware dirty bit during writeback, later buffers get freed, and then page unmapped. Fix the issue by ignoring s390 HW dirty bit for page cache pages of mappings with mapping_cap_account_dirty(). This is safe because for such mappings when a page gets marked as writeable in PTE it is also marked dirty in do_wp_page() or do_page_fault(). When the dirty bit is cleared by clear_page_dirty_for_io(), the page gets writeprotected in page_mkclean(). So pagecache page is writeable if and only if it is dirty. Thanks to Hugh Dickins for pointing out mapping has to have mapping_cap_account_dirty() for things to work and proposing a cleaned up variant of the patch. The patch has survived about two hours of running fsx-linux on tmpfs while heavily swapping and several days of running on out build machines where the original problem was triggered.

It's unlikely to happen unless something is wrong with the command ring pointers, so add some debugging in case it happens.

671415b Miao Xie 16 October 2012, 11:26:46 UTC Btrfs: fix deadlock caused by the nested chunk allocation Steps to reproduce: # mkfs.btrfs -m raid1 <disk1> <disk2> # btrfstune -S 1 <disk1> # mount <disk1> <mnt> # btrfs device add <disk3> <disk4> <mnt> # mount -o remount,rw <mnt> # dd if=/dev/zero of=<mnt>/tmpfile bs=1M count=1 Deadlock happened. It is because of the nested chunk allocation. When we wrote the data into the filesystem, we would allocate the data chunk because there was no data chunk in the filesystem. At the end of the data chunk allocation, we should insert the metadata of the data chunk into the extent tree, but there was no raid1 chunk, so we tried to lock the chunk allocation mutex to allocate the new chunk, but we had held the mutex, the deadlock happened. By rights, we would allocate the raid1 chunk when we added the second device because the profile of the seed filesystem is raid1 and we had two devices. But we didn't do that in fact. It is because the last step of the first device insertion didn't commit the transaction. So when we added the second device, we didn't cow the tree, and just inserted the relative metadata into the leaves which were generated by the first device insertion, and its profile was dup. So, I fix this problem by commiting the transaction at the end of the first device insertion. Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> 25 October 2012, 19:47:00 UTC

661bec6 Gabriel de Perthuis 10 October 2012, 14:50:47 UTC Fix a sign bug causing invalid memory access in the ino_paths ioctl. To see the problem, create many hardlinks to the same file (120 should do it), then look up paths by inode with: ls -i btrfs inspect inode-resolve -v $ino /mnt/btrfs I noticed the memory layout of the fspath->val data had some irregularities (some unnecessary gaps that stop appearing about halfway), so I'm not sure there aren't any bugs left in it. 25 October 2012, 19:39:47 UTC

80c0075 Johan Hovold 25 October 2012, 16:56:34 UTC USB: mos7840: fix port-data memory leak Fix port-data memory leak by moving port data allocation and deallocation to port_probe and port_remove. Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no driver is bound) the port private data is no longer freed at release as it is no longer accessible. Note that the indentation was kept intact using a do-while(0) in order to facilitate review. A follow-up patch will remove it. Compile-only tested.

Beyond setup, it is normally used to determine if runtime services are available and we will have none. This will resolve issues stemming from efivars modprobe panicking on a 32/64-bit setup, as well as some reboot issues on similar setups.
