commit 6096d91a upstream. The metadata space map has a simplified 'bootstrap' mode that is operational when extending the space maps. Whilst in this mode it's possible for some refcount decrement operations to become queued (eg, as a result of shadowing one of the bitmap indexes). These decrements were not being applied when switching out of bootstrap mode. The effect of this bug was the leaking of a 4k metadata block. This is detected by the latest version of thin_check as a non fatal error. Signed-off-by:

commit b9bcc919 upstream. The memmap freeing code in free_unused_memmap() computes the end of each memblock by adding the memblock size onto the base. However, if SPARSEMEM is enabled then the value (start) used for the base may already have been rounded downwards to work out which memmap entries to free after the previous memblock. This may cause memmap entries that are in use to get freed. In general, you're not likely to hit this problem unless there are at least 2 memblocks and one of them is not aligned to a sparsemem section boundary. Note that carve-outs can increase the number of memblocks by splitting the regions listed in the device tree. This problem doesn't occur with SPARSEMEM_VMEMMAP, because the vmemmap code deals with freeing the unused regions of the memmap instead of requiring the arch code to do it. This patch gets the memblock base out of the memblock directly when computing the block end address to ensure the correct value is used. Signed-off-by:

commit 85e84ba3 upstream. On VM entry, we disable access to the VFP registers in order to perform a lazy save/restore of these registers. On VM exit, we restore access, test if we did enable them before, and save/restore the guest/host registers if necessary. In this sequence, the FPEXC register is always accessed, irrespective of the trapping configuration. If the guest didn't touch the VFP registers, then the HCPTR access has now enabled such access, but we're missing a barrier to ensure architectural execution of the new HCPTR configuration. If the HCPTR access has been delayed/reordered, the subsequent access to FPEXC will cause a trap, which we aren't prepared to handle at all. The same condition exists when trapping to enable VFP for the guest. The fix is to introduce a barrier after enabling VFP access. In the vmexit case, it can be relaxed to only takes place if the guest hasn't accessed its view of the VFP registers, making the access to FPEXC safe. The set_hcptr macro is modified to deal with both vmenter/vmexit and vmtrap operations, and now takes an optional label that is branched to when the guest hasn't touched the VFP registers.

commit 921cc294 upstream. The way the mask is generated in regmap_field_init() is wrong. Indeed, a field initialized with msb = 31 and lsb = 0 provokes a shift overflow while calculating the mask field. On some 32 bits architectures, such as x86, the generated mask is 0, instead of the expected 0xffffffff. This patch uses GENMASK() to fix the problem, as this macro is already safe regarding shift overflow. Signed-off-by:

commit 4b200b46 upstream. This fixes a several year old regression that I found while trying to get the Yoga 3 11 to work. The ideapad_rfk_set function is meant to send a command to the embedded controller through ACPI, but as of c1f73658, it sends the index of the rfkill device instead of the command, and ignores the opcode field. This changes it back to the original behavior, which indeed flips the rfkill state as seen in the debugfs interface. Signed-off-by:

commit 6f6a6fda upstream. If updating journal superblock fails after journal data has been flushed, the error is omitted and this will mislead the caller as a normal case. In ocfs2, the checkpoint will be treated successfully and the other node can get the lock to update. Since the sb_start is still pointing to the old log block, it will rewrite the journal data during journal recovery by the other node. Thus the new updates will be overwritten and ocfs2 corrupts. So in above case we have to return the error, and ocfs2_commit_cache will take care of the error and prevent the other node to do update first. And only after recovering journal it can do the new updates. The issue discussion mail can be found at: https://oss.oracle.com/pipermail/ocfs2-devel/2015-June/010856.html http://comments.gmane.org/gmane.comp.file-systems.ext4/48841 [ Fixed bug in patch which allowed a non-negative error return from jbd2_cleanup_journal_tail() to leak out of jbd2_fjournal_flush(); this was causing xfstests ext4/306 to fail. -- Ted ] Reported-by:

commit bdf96838 upstream. The commit cf108bca: "ext4: Invert the locking order of page_lock and transaction start" caused __ext4_journalled_writepage() to drop the page lock before the page was written back, as part of changing the locking order to jbd2_journal_start -> page_lock. However, this introduced a potential race if there was a truncate racing with the data=journalled writeback mode. Fix this by grabbing the page lock after starting the journal handle, and then checking to see if page had gotten truncated out from under us. This fixes a number of different warnings or BUG_ON's when running xfstests generic/086 in data=journalled mode, including: jbd2_journal_dirty_metadata: vdc-8: bad jh for block 115643: transaction (ee3fe7 c0, 164), jh->b_transaction ( (null), 0), jh->b_next_transaction ( (null), 0), jlist 0 - and - kernel BUG at /usr/projects/linux/ext4/fs/jbd2/transaction.c:2200! ...

commit 93563a6a upstream. For TX transactions, the TXCOMP bit in the Status Register is cleared when the first data is written into the Transmit Holding Register. In the lines from at91_do_twi_transfer(): at91_twi_write_data_dma(dev); at91_twi_write(dev, AT91_TWI_IER, AT91_TWI_TXCOMP); the TXCOMP interrupt may be enabled before the DMA controller has actually started to write into the THR. In such a case, the TXCOMP bit is still set into the Status Register so the interrupt is triggered immediately. The driver understands that a transaction completion has occurred but this transaction hasn't started yet. Hence the TXCOMP interrupt is no longer enabled by at91_do_twi_transfer() but instead by at91_twi_write_data_dma_callback(). Also, the TXCOMP bit in the Status Register in not a clear on read flag but a snapshot of the transmission state at the time the Status Register is read. When a NACK error is dectected by the I2C controller, the TXCOMP, NACK and TXRDY bits are set together to 1 in the SR. If enabled, the TXCOMP interrupt is triggered at the same time. Also setting the TXRDY to 1 triggers the DMA controller to write the next data into the THR. Such a write resets the TXCOMP bit to 0 in the SR. So depending on when the interrupt handler reads the SR, it may fail to detect the NACK error if it relies on the TXCOMP bit. The NACK bit and its interrupt should be used instead. For RX transactions, the TXCOMP bit in the Status Register is cleared when the START bit is set into the Control Register. However to unify the management of the TXCOMP bit when the DMA controller is used, the TXCOMP interrupt is now enabled by the DMA callbacks for both TX and RX transfers. Signed-off-by:

commit 90f91b12 upstream. It seems Broadcom released two devices with conflicting device id. There are for sure 14e4:4321 PCI devices with BCM4321 (N-PHY) chipset, they can be found in routers, e.g. Netgear WNR834Bv2. However, according to Broadcom public sources 0x4321 is also used for 5 GHz BCM4306 (G-PHY). It's unsure if they meant PCI device id, or "virtual" id (from SPROM). To distinguish these devices lets check PHY type (G vs. N). Signed-off-by:

commit 9fc2b4b4 upstream. Before calling into the filesystem, vfs_setxattr calls security_inode_setxattr, which ends up calling selinux_inode_setxattr in our case. That returns -EOPNOTSUPP whenever SBLABEL_MNT is not set. SBLABEL_MNT was supposed to be set by sb_finish_set_opts, which sets it only if selinux_is_sblabel_mnt returns true. The selinux_is_sblabel_mnt logic was broken by eadcabc6 "SELinux: do all flags twiddling in one place", which didn't take into the account the SECURITY_FS_USE_NATIVE behavior that had been introduced for nfs with eb9ae686 "SELinux: Add new labeling type native labels". This caused setxattr's of security labels over NFSv4.2 to fail. Cc: Eric Paris <eparis@redhat.com> Cc: David Quigley <dpquigl@davequigley.com> Reported-by:

commit 2fa19535 upstream. If objects are moved back from system memory to VRAM (and spice id created again) memory is already initialized so we need to set flag to not clear memory. If you don't do it after a while using desktop many images turns to black or transparents. Signed-off-by:

commit 8c6cf9cc upstream. Ignore an existing mount if the locked readonly, nodev or atime attributes are less permissive than the desired attributes of the new mount. On success ensure the new mount locks all of the same readonly, nodev and atime attributes as the old mount. The nosuid and noexec attributes are not checked here as this change is destined for stable and enforcing those attributes causes a regression in lxc and libvirt-lxc where those applications will not start and there are no known executables on sysfs or proc and no known way to create exectuables without code modifications Fixes: e51db735 ("userns: Better restrictions on when proc and sysfs can be mounted") Signed-off-by:
