commit f7e9e358 upstream. This problem appears to have been introduced in 2.6.29 by commit 93197a36 "Rewrite sysfs processor cache info code". This caused lscpu to error out on at least e500v2 devices, eg: error: cannot open /sys/devices/system/cpu/cpu0/cache/index2/size: No such file or directory Some embedded powerpc systems use cache-size in DTS for the unified L2 cache size, not d-cache-size, so we need to allow for both DTS names. Added a new CACHE_TYPE_UNIFIED_D cache_type_info structure to handle this. Fixes: 93197a36 ("powerpc: Rewrite sysfs processor cache info code") Signed-off-by:

commit 91bf0c2d upstream. The functions snd_emu10k1_proc_spdif_read and snd_emu1010_fpga_read acquire the emu_lock before accessing the FPGA. The function used to access the FPGA (snd_emu1010_fpga_read) also tries to take the emu_lock which causes a deadlock. Remove the outer locking in the proc-functions (guarding only the already safe fpga read) to prevent this deadlock. [removed superfluous flags variables too -- tiwai] Signed-off-by:

commit b4491592 upstream. The comment line regarding IOMMU_INIT and IOMMU_INIT_FINISH macros is incorrect: "The standard vs the _FINISH differs in that the _FINISH variant will continue detecting other IOMMUs in the call list..." It should be "..the *standard* variant will continue detecting..." Fix that. Also, make it readable while at it. Signed-off-by:

commit bd884149 upstream. On ASUS TP500LN and X750JN, the touchpad absolute mode is reset each time set_rate is done. In order to fix this, we will verify the firmware version, and if it matches the one in those laptops, the set_rate function is overloaded with a function elantech_set_rate_restore_reg_07 that performs the set_rate with the original function, followed by a restore of reg_07 (the register that sets the absolute mode on elantech v4 hardware). Also the ASUS TP500LN and X750JN firmware version, capabilities, and button constellation is added to elantech.c Reported-and-tested-by:

commit 2e7056c4 upstream. Looking over the implementation for jhash2 and comparing it to jhash_3words I realized that the two hashes were in fact very different. Doing a bit of digging led me to "The new jhash implementation" in which lookup2 was supposed to have been replaced with lookup3. In reviewing the patch I noticed that jhash2 had originally initialized a and b to JHASH_GOLDENRATIO and c to initval, but after the patch a, b, and c were initialized to initval + (length << 2) + JHASH_INITVAL. However the changes in jhash_3words simply replaced the initialization of a and b with JHASH_INITVAL. This change corrects what I believe was an oversight so that a, b, and c in jhash_3words all have the same value added consisting of initval + (length << 2) + JHASH_INITVAL so that jhash2 and jhash_3words will now produce the same hash result given the same inputs.

commit e12fb972 upstream. Previously commit 14ece102 added a support for for syncing parent directory of newly created inodes to make sure that the inode is not lost after a power failure in no-journal mode. However this does not work in majority of cases, namely: - if the directory has inline data - if the directory is already indexed - if the directory already has at least one block and: - the new entry fits into it - or we've successfully converted it to indexed So in those cases we might lose the inode entirely even after fsync in the no-journal mode. This also includes ext2 default mode obviously. I've noticed this while running xfstest generic/321 and even though the test should fail (we need to run fsck after a crash in no-journal mode) I could not find a newly created entries even when if it was fsynced before. Fix this by adjusting the ext4_add_entry() successful exit paths to set the inode EXT4_STATE_NEWENTRY so that fsync has the chance to fsync the parent directory as well. Signed-off-by:

commit 8defb336 upstream. Usually ELF_ET_DYN_BASE is 2/3 of TASK_SIZE. With 3G/1G user/kernel split this is not so, because 2*TASK_SIZE overflows 32 bits, so the actual value of ELF_ET_DYN_BASE is: (2 * TASK_SIZE / 3) = 0x2a000000 When ASLR is disabled PIE binaries will load at ELF_ET_DYN_BASE address. On 32bit platforms AddressSanitzer uses addresses [0x20000000 - 0x40000000] for shadow memory [1]. So ASan doesn't work for PIE binaries when ASLR disabled as it fails to map shadow memory. Also after Kees's 'split ET_DYN ASLR from mmap ASLR' patchset PIE binaries has a high chance of loading somewhere in between [0x2a000000 - 0x40000000] even if ASLR enabled. This makes ASan with PIE absolutely incompatible. Fix overflow by dividing TASK_SIZE prior to multiplying. After this patch ELF_ET_DYN_BASE equals to (for CONFIG_VMSPLIT_3G=y): (TASK_SIZE / 3 * 2) = 0x7f555554 [1] https://code.google.com/p/address-sanitizer/wiki/AddressSanitizerAlgorithm#MappingSigned-off-by:

commit dcc82f47 upstream. While committing a transaction we free the log roots before we write the new super block. Freeing the log roots implies marking the disk location of every node/leaf (metadata extent) as pinned before the new super block is written. This is to prevent the disk location of log metadata extents from being reused before the new super block is written, otherwise we would have a corrupted log tree if before the new super block is written a crash/reboot happens and the location of any log tree metadata extent ended up being reused and rewritten. Even though we pinned the log tree's metadata extents, we were issuing a discard against them if the fs was mounted with the -o discard option, resulting in corruption of the log tree if a crash/reboot happened before writing the new super block - the next time the fs was mounted, during the log replay process we would find nodes/leafs of the log btree with a content full of zeroes, causing the process to fail and require the use of the tool btrfs-zero-log to wipeout the log tree (and all data previously fsynced becoming lost forever). Fix this by not doing a discard when pinning an extent. The discard will be done later when it's safe (after the new super block is committed) at extent-tree.c:btrfs_finish_extent_commit().

commit f16db807 upstream. In some of the 'out_not_moved' error paths, lnum may be used uninitialized. Don't ignore the warning; let's fix it. This uninitialized variable doesn't have much visible effect in the end, since we just schedule the PEB for erasure, and its LEB number doesn't really matter (it just gets printed in debug messages).

commit 2c20d92d upstream. the lcd type as defined in the Kconfig is not matching in the code. as a result the rs, rw and en pins were getting interchanged. Kconfig defines the value of PANEL_LCD to be 1 if we select custom configuration but in the code LCD_TYPE_CUSTOM is defined as 5. my hardware is LCD_TYPE_CUSTOM, but the pins were assigned to it as pins of LCD_TYPE_OLD, and it was not working. Now values are corrected with referenece to the values defined in Kconfig and it is working. checked on JHD204A lcd with LCD_TYPE_CUSTOM configuration. Signed-off-by:

commit 1915a718 upstream. The return value of power_supply_register() call was not checked and even on error probe() function returned 0. If registering failed then during unbind the driver tried to unregister power supply which was not actually registered. This could lead to memory corruption because power_supply_unregister() unconditionally cleans up given power supply. Fix this by checking return status of power_supply_register() call. In case of failure, clean up sysfs entries and fail the probe. Signed-off-by:

commit 08e83316 upstream. There is a race condition between e1000_change_mtu's cleanups and netpoll, when we change the MTU across jumbo size: Changing MTU frees all the rx buffers: e1000_change_mtu -> e1000_down -> e1000_clean_all_rx_rings -> e1000_clean_rx_ring Then, close to the end of e1000_change_mtu: pr_info -> ... -> netpoll_poll_dev -> e1000_clean -> e1000_clean_rx_irq -> e1000_alloc_rx_buffers -> e1000_alloc_frag And when we come back to do the rest of the MTU change: e1000_up -> e1000_configure -> e1000_configure_rx -> e1000_alloc_jumbo_rx_buffers alloc_jumbo finds the buffers already != NULL, since data (shared with page in e1000_rx_buffer->rxbuf) has been re-alloc'd, but it's garbage, or at least not what is expected when in jumbo state.

commit 3b05ac38 upstream. The app_tcp_pkt_out() function expects "*diff" to be set and ends up using uninitialized data if CONFIG_IP_VS_IPV6 is turned on. The same issue is there in app_tcp_pkt_in(). Thanks to Julian Anastasov for noticing that. Signed-off-by:

commit 579eb62a upstream. commit f5a41847 ("ipvs: move ip_route_me_harder for ICMP") from 2.6.37 introduced ip_route_me_harder() call for responses to local clients, so that we can provide valid rt_src after SNAT. It was used by TCP to provide valid daddr for ip_send_reply(). After commit 0a5ebb80 ("ipv4: Pass explicit daddr arg to ip_send_reply()." from 3.0 this rerouting is not needed anymore and should be avoided, especially in LOCAL_IN. Fixes 3.12.33 crash in xfrm reported by Florian Wiessner: "3.12.33 - BUG xfrm_selector_match+0x25/0x2f6" Reported-by:

commit f20fbaad upstream. `spidev_message()` sums the lengths of the individual SPI transfers to determine the overall SPI message length. It restricts the total length, returning an error if too long, but it does not check for arithmetic overflow. For example, if the SPI message consisted of two transfers and the first has a length of 10 and the second has a length of (__u32)(-1), the total length would be seen as 9, even though the second transfer is actually very long. If the second transfer specifies a null `rx_buf` and a non-null `tx_buf`, the `copy_from_user()` could overrun the spidev's pre-allocated tx buffer before it reaches an invalid user memory address. Fix it by checking that neither the total nor the individual transfer lengths exceed the maximum allowed value. Thanks to Dan Carpenter for reporting the potential integer overflow. Signed-off-by:

commit 330966e5 upstream. skb_gso_segment has three possible return values: 1. a pointer to the first segmented skb 2. an errno value (IS_ERR()) 3. NULL. This can happen when GSO is used for header verification. However, several callers currently test IS_ERR instead of IS_ERR_OR_NULL and would oops when NULL is returned. Note that these call sites should never actually see such a NULL return value; all callers mask out the GSO bits in the feature argument. However, there have been issues with some protocol handlers erronously not respecting the specified feature mask in some cases. It is preferable to get 'have to turn off hw offloading, else slow' reports rather than 'kernel crashes'. Signed-off-by:
