2014-11-13UBIFS: fix free log space calculationArtem Bityutskiy
commit ba29e721eb2df6df8f33c1f248388bb037a47914 upstream. Hu (hujianyang <hujianyang@huawei.com>) discovered an issue in the 'empty_log_bytes()' function, which calculates how many bytes are left in the log: " If 'c->lhead_lnum + 1 == c->ltail_lnum' and 'c->lhead_offs == c->leb_size', 'h' would equalent to 't' and 'empty_log_bytes()' would return 'c->log_bytes' instead of 0. " At this point it is not clear what would be the consequences of this, and whether this may lead to any problems, but this patch addresses the issue just in case.

2014-11-13UBIFS: fix a race conditionArtem Bityutskiy
commit 052c28073ff26f771d44ef33952a41d18dadd255 upstream. Hu (hujianyang@huawei.com) discovered a race condition which may lead to a situation when UBIFS is unable to mount the file-system after an unclean reboot. The problem is theoretical, though. In UBIFS, we have the log, which basically a set of LEBs in a certain area. The log has the tail and the head. Every time user writes data to the file-system, the UBIFS journal grows, and the log grows as well, because we append new reference nodes to the head of the log. So the head moves forward all the time, while the log tail stays at the same position. At any time, the UBIFS master node points to the tail of the log. When we mount the file-system, we scan the log, and we always start from its tail, because this is where the master node points to. The only occasion when the tail of the log changes is the commit operation. The commit operation has 2 phases - "commit start" and "commit end". The former is relatively short, and does not involve much I/O. During this phase we mostly just build various in-memory lists of the things which have to be written to the flash media during "commit end" phase. During the commit start phase, what we do is we "clean" the log. Indeed, the commit operation will index all the data in the journal, so the entire journal "disappears", and therefore the data in the log become unneeded. So we just move the head of the log to the next LEB, and write the CS node there. This LEB will be the tail of the new log when the commit operation finishes. When the "commit start" phase finishes, users may write more data to the file-system, in parallel with the ongoing "commit end" operation. At this point the log tail was not changed yet, it is the same as it had been before we started the commit. The log head keeps moving forward, though. The commit operation now needs to write the new master node, and the new master node should point to the new log tail. After this the LEBs between the old log tail and the new log tail can be unmapped and re-used again. And here is the possible problem. We do 2 operations: (a) We first update the log tail position in memory (see 'ubifs_log_end_commit()'). (b) And then we write the master node (see the big lock of code in 'do_commit()'). But nothing prevents the log head from moving forward between (a) and (b), and the log head may "wrap" now to the old log tail. And when the "wrap" happens, the contends of the log tail gets erased. Now a power cut happens and we are in trouble. We end up with the old master node pointing to the old tail, which was erased. And replay fails because it expects the master node to point to the correct log tail at all times. This patch merges the abovementioned (a) and (b) operations by moving the master node change code to the 'ubifs_log_end_commit()' function, so that it runs with the log mutex locked, which will prevent the log from being changed benween operations (a) and (b).

commit 07e19dff63e3d5d6500d831e36554ac9b1b0560e upstream. The 'mst_mutex' is not needed since because 'ubifs_write_master()' is only called on the mount path and commit path. The mount path is sequential and there is no parallelism, and the commit path is also serialized - there is only one commit going on at a time.

2014-11-13fs: allow open(dir, O_TMPFILE|..., 0) with mode 0Eric Rannaud
commit 69a91c237ab0ebe4e9fdeaf6d0090c85275594ec upstream. The man page for open(2) indicates that when O_CREAT is specified, the 'mode' argument applies only to future accesses to the file: Note that this mode applies only to future accesses of the newly created file; the open() call that creates a read-only file may well return a read/write file descriptor. The man page for open(2) implies that 'mode' is treated identically by O_CREAT and O_TMPFILE. O_TMPFILE, however, behaves differently: int fd = open("/tmp", O_TMPFILE | O_RDWR, 0); assert(fd == -1); assert(errno == EACCES); int fd = open("/tmp", O_TMPFILE | O_RDWR, 0600); assert(fd > 0); For O_CREAT, do_last() sets acc_mode to MAY_OPEN only: if (*opened & FILE_CREATED) { /* Don't check for write permission, don't truncate */ open_flag &= ~O_TRUNC; will_truncate = false; acc_mode = MAY_OPEN; path_to_nameidata(path, nd); goto finish_open_created; } But for O_TMPFILE, do_tmpfile() passes the full op->acc_mode to may_open(). This patch lines up the behavior of O_TMPFILE with O_CREAT. After the inode is created, may_open() is called with acc_mode = MAY_OPEN, in do_tmpfile(). A different, but related glibc bug revealed the discrepancy: https://sourceware.org/bugzilla/show_bug.cgi?id=17523 The glibc lazily loads the 'mode' argument of open() and openat() using va_arg() only if O_CREAT is present in 'flags' (to support both the 2 argument and the 3 argument forms of open; same idea for openat()). However, the glibc ignores the 'mode' argument if O_TMPFILE is in 'flags'. On x86_64, for open(), it magically works anyway, as 'mode' is in RDX when entering open(), and is still in RDX on SYSCALL, which is where the kernel looks for the 3rd argument of a syscall. But openat() is not quite so lucky: 'mode' is in RCX when entering the glibc wrapper for openat(), while the kernel looks for the 4th argument of a syscall in R10. Indeed, the syscall calling convention differs from the regular calling convention in this respect on x86_64. So the kernel sees mode = 0 when trying to use glibc openat() with O_TMPFILE, and fails with EACCES.

2014-11-13fs: Fix theoretical division by 0 in super_cache_scan().Tetsuo Handa
commit 475d0db742e3755c6b267f48577ff7cbb7dfda0d upstream. total_objects could be 0 and is used as a denom. While total_objects is a "long", total_objects == 0 unlikely happens for 3.12 and later kernels because 32-bit architectures would not be able to hold (1 << 32) objects. However, total_objects == 0 may happen for kernels between 3.1 and 3.11 because total_objects in prune_super() was an "int" and (e.g.) x86_64 architecture might be able to hold (1 << 32) objects.

2014-11-13fs: make cont_expand_zero interruptibleMikulas Patocka
commit c2ca0fcd202863b14bd041a7fece2e789926c225 upstream. This patch makes it possible to kill a process looping in cont_expand_zero. A process may spend a lot of time in this function, so it is desirable to be able to kill it. It happened to me that I wanted to copy a piece data from the disk to a file. By mistake, I used the "seek" parameter to dd instead of "skip". Due to the "seek" parameter, dd attempted to extend the file and became stuck doing so - the only possibility was to reset the machine or wait many hours until the filesystem runs out of space and cont_expand_zero fails. We need this patch to be able to terminate the process.

2014-11-13mmc: rtsx_pci_sdmmc: fix incorrect last byte in R2 responseRoger Tseng
commit d1419d50c1bf711e9fd27b516a739c86b23f7cf9 upstream. Current code erroneously fill the last byte of R2 response with an undefined value. In addition, the controller actually 'offloads' the last byte (CRC7, end bit) while receiving R2 response and thus it's impossible to get the actual value. This could cause mmc stack to obtain inconsistent CID from the same card after resume and misidentify it as a different card. Fix by assigning dummy CRC and end bit: {7'b0, 1} = 0x1 to the last byte of R2.

The CSB series appears to support 64-KB DMA transfers, as tests on a machine with an SAI2 motherboard containing a Broadcom CSB5 IDE Controller (vendor and device IDs: 1166:0212) showed no problems with 64-KB DMA transfers. This problem was first discovered when attempting to install openSUSE from a DVD on a machine with an STL2 motherboard. Using the pata_serverworks module, older releases of openSUSE will not install at all due to the timeouts. Releases of openSUSE prior to 11.3 can be installed by disabling the pata_serverworks module using the brokenmodules boot parameter, which causes the serverworks module to be used instead. Recent releases of openSUSE (12.2 and later) include better error recovery and will install, though very slowly. On all openSUSE releases, the problem can be recreated on a machine containing a Broadcom OSB4 IDE Controller by mounting an install DVD and running a command similar to the following: find /mnt -type f -print | xargs cat > /dev/null The patch below corrects the problem. Similar to the other ATA drivers that do not support 64-KB DMA transfers, the patch changes the ata_port_operations qc_prep vector to point to a routine that breaks any 64-KB segment into two 32-KB segments and changes the scsi_host_template sg_tablesize element to reduce by half the number of scatter/gather elements allowed. These two changes affect only the OSB4. Signed-off-by: Scott Carter <ccscott@funsoft.com> Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jiri Slaby <jslaby@suse.cz>

In 3.12, this was introduced by a0b8d8d906d267987d507138003048c5fdf774 ("regmap: fix possible ZERO_SIZE_PTR pointer dereferencing error.") which improperly back-ported d6b41cb06044a7d895db82bdd54f6e4219970510. This issue was found during review of Ubuntu Trusty 3.13.0-40.68 kernel to prepare Ksplice rebootless updates. Fixes: f5942dd ("regmap: fix possible ZERO_SIZE_PTR pointer dereferencing error.")

2014-11-13crypto: more robust crypto_memneqCesar Eduardo Barros
commit fe8c8a126806fea4465c43d62a1f9d273a572bf5 upstream. [Only use the compiler.h portion of this patch, to get the OPTIMIZER_HIDE_VAR() macro, which we need for other -stable patches - gregkh] Disabling compiler optimizations can be fragile, since a new optimization could be added to -O0 or -Os that breaks the assumptions the code is making. Instead of disabling compiler optimizations, use a dummy inline assembly (based on RELOC_HIDE) to block the problematic kinds of optimization, while still allowing other optimizations to be applied to the code. The dummy inline assembly is added after every OR, and has the accumulator variable as its input and output. The compiler is forced to assume that the dummy inline assembly could both depend on the accumulator variable and change the accumulator variable, so it is forced to compute the value correctly before the inline assembly, and cannot assume anything about its value after the inline assembly. This change should be enough to make crypto_memneq work correctly (with data-independent timing) even if it is inlined at its call sites. That can be done later in a followup patch. Compile-tested on x86_64.

commit 8500d791c458ccbbb3e2d3fa9a0320ffd5729069 upstream. btmrvl_add_card() function calls kthread_run that might return error (e.g. if current thread is killed). If one tries to use the error value as a pointer then invalid memory access oops happens. Check kthread_run() return value, if it is an error then release resources correctly. TEST=boot computer with BT modules enabled. I see the error message that BT device initialization failed. Now kernel does not crash.

2014-11-13Bluetooth: Fix endian and alignment issue with ath3k version handlingMarcel Holtmann
commit 72dd2b2a44d82118714e0821fa16c65f9e40eb00 upstream. The ath3k driver is treating the version information badly when it comes to loading the right firmware version and comparing that it actually matches with the hardware. Initially this showed up as this: CHECK drivers/bluetooth/ath3k.c drivers/bluetooth/ath3k.c:373:17: warning: cast to restricted __le32 drivers/bluetooth/ath3k.c:435:17: warning: cast to restricted __le32 However when fixing this by actually using __packed and __le32 for the ath3_version structure, more issues came up: CHECK drivers/bluetooth/ath3k.c drivers/bluetooth/ath3k.c:381:32: warning: incorrect type in assignment (different base types) drivers/bluetooth/ath3k.c:381:32: expected restricted __le32 [usertype] rom_version drivers/bluetooth/ath3k.c:381:32: got int [signed] <noident> drivers/bluetooth/ath3k.c:382:34: warning: incorrect type in assignment (different base types) drivers/bluetooth/ath3k.c:382:34: expected restricted __le32 [usertype] build_version drivers/bluetooth/ath3k.c:382:34: got int [signed] <noident> drivers/bluetooth/ath3k.c:386:28: warning: restricted __le32 degrades to integer drivers/bluetooth/ath3k.c:386:56: warning: restricted __le32 degrades to integer This patch fixes every instance of the firmware version handling and makes sure it is endian safe and uses proper unaligned access.

2014-11-13HID: usbhid: enable NO_INIT_REPORTS quirk for Semico USB KeykoardJiri Kosina
commit 9ea63c439c5dffcb7c46c741929fe74b31b9676b upstream. The device which identifies itself as a "USB Keykoard" (no typo) with VID:PID 1a2c:0023 does not seem to be handling the reports initialization very well. This results in a "usb_submit_urb(ctrl) failed: -1" message from the kernel when connected, and a delay before its initialization.

This is in v3.12.22 as commit 723ac81c8671b3a095d9eb303974c7bc9964b506. The affected code was removed in 3.14 by commit 4ac7249ea5a0ceef9f8269f63f33cc873c3fac61 (nfsd: use get_acl and ->set_acl). The ->set_acl methods are already able to cope with a NULL argument. So this is not needed for >= 3.14.

[ Upstream commit 5188cd44c55db3e92cd9e77a40b5baa7ed4340f7 ] UFO is now disabled on all drivers that work with virtio net headers, but userland may try to send UFO/IPv6 packets anyway. Instead of sending with ID=0, we should select identifiers on their behalf (as we used to).
