commit b9cf625d upstream. If ext4_convert_inline_data() was called on a directory with inline data, the filesystem was left in an inconsistent state (as considered by e2fsck) because the file size was not increased to cover the new block. This happened because the inode was not marked dirty after i_disksize was updated. Fix this by marking the inode dirty at the end of ext4_finish_convert_inline_dir(). This bug was probably not noticed before because most users mark the inode dirty afterwards for other reasons. But if userspace executed FS_IOC_SET_ENCRYPTION_POLICY with invalid parameters, as exercised by 'kvm-xfstests -c adv generic/396', then the inode was never marked dirty after updating i_disksize.

commit f259ca3e upstream. Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer or accessing memory beyond the endpoint array should a malicious device lack the expected endpoints. Note that the endpoint access that causes the NULL-deref is currently only used for debugging purposes during probe so the oops only happens when dynamic debugging is enabled. This means the driver could be rewritten to continue to accept device with only two endpoints, should such devices exist. Fixes: 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:

commit 3243367b upstream. Some USB 2.0 devices erroneously report millisecond values in bInterval. The generic config code manages to catch most of them, but in some cases it's not completely enough. The case at stake here is a USB 2.0 braille device, which wants to announce 10ms and thus sets bInterval to 10, but with the USB 2.0 computation that yields to 64ms. It happens that one can type fast enough to reach this interval and get the device buffers overflown, leading to problematic latencies. The generic config code does not catch this case because the 64ms is considered a sane enough value. This change thus adds a USB_QUIRK_LINEAR_FRAME_INTR_BINTERVAL quirk to mark devices which actually report milliseconds in bInterval, and marks Vario Ultra devices as needing it. Signed-off-by:

commit c520ff3d upstream. When snd_seq_pool_done() is called, it marks the closing flag to refuse the further cell insertions. But snd_seq_pool_done() itself doesn't clear the cells but just waits until all cells are cleared by the caller side. That is, it's racy, and this leads to the endless stall as syzkaller spotted. This patch addresses the racy by splitting the setup of pool->closing flag out of snd_seq_pool_done(), and calling it properly before snd_seq_pool_done().

commit b581a585 upstream. Since ceph.git commit 4e28f9e63644 ("osd/OSDMap: clear osd_info, osd_xinfo on osd deletion"), weight is set to IN when OSD is deleted. This changes the result of applying an incremental for clients, not just OSDs. Because CRUSH computations are obviously affected, pre-4e28f9e63644 servers disagree with post-4e28f9e63644 clients on object placement, resulting in misdirected requests. Mirrors ceph.git commit a6009d1039a55e2c77f431662b3d6cc5a8e8e63f.

[ Upstream commit 7df9c246 ] Dmitry has reported that a BUG_ON() condition in unix_notinflight() may be triggered by a simple code that forwards unix socket in an SCM_RIGHTS message. That is caused by incorrect unix socket GC implementation in unix_gc(). The GC first collects list of candidates, then (a) decrements their "children's" inflight counter, (b) checks which inflight counters are now 0, and then (c) increments all inflight counters back. (a) and (c) are done by calling scan_children() with inc_inflight or dec_inflight as the second argument. Commit 6209344f ("net: unix: fix inflight counting bug in garbage collector") changed scan_children() such that it no longer considers sockets that do not have UNIX_GC_CANDIDATE flag. It also added a block of code that that unsets this flag _before_ invoking scan_children(, dec_iflight, ). This may lead to incorrect inflight counters for some sockets. This change fixes this bug by changing order of operations: UNIX_GC_CANDIDATE is now unset only after all inflight counters are restored to the original state. kernel BUG at net/unix/garbage.c:149!

[ Upstream commit 22a0e18e ] I mistakenly added the code to release sk->sk_frag in sk_common_release() instead of sk_destruct() TCP sockets using sk->sk_allocation == GFP_ATOMIC do no call sk_common_release() at close time, thus leaking one (order-3) page. iSCSI is using such sockets.

[ Upstream commit 4e684f59 ] Sometimes firmware may not properly initialize I347AT4_PAGE_SELECT causing the probe of an igb i210 NIC to fail. This patch adds an addition zeroing of this register during igb_get_phy_id to workaround this issue. Thanks for Jochen Henneberg for the idea and original patch. Signed-off-by:

[ Upstream commit c74fd80f ] Revert the main part of commit: af42b8d1 ("xen: fix MSI setup and teardown for PV on HVM guests") That commit introduced reading the pci device's msi message data to see if a pirq was previously configured for the device's msi/msix, and re-use that pirq. At the time, that was the correct behavior. However, a later change to Qemu caused it to call into the Xen hypervisor to unmap all pirqs for a pci device, when the pci device disables its MSI/MSIX vectors; specifically the Qemu commit: c976437c7dba9c7444fb41df45468968aaa326ad ("qemu-xen: free all the pirqs for msi/msix when driver unload") Once Qemu added this pirq unmapping, it was no longer correct for the kernel to re-use the pirq number cached in the pci device msi message data. All Qemu releases since 2.1.0 contain the patch that unmaps the pirqs when the pci device disables its MSI/MSIX vectors. This bug is causing failures to initialize multiple NVMe controllers under Xen, because the NVMe driver sets up a single MSIX vector for each controller (concurrently), and then after using that to talk to the controller for some configuration data, it disables the single MSIX vector and re-configures all the MSIX vectors it needs. So the MSIX setup code tries to re-use the cached pirq from the first vector for each controller, but the hypervisor has already given away that pirq to another controller, and its initialization fails. This is discussed in more detail at: https://lists.xen.org/archives/html/xen-devel/2017-01/msg00447.html Fixes: af42b8d1 ("xen: fix MSI setup and teardown for PV on HVM guests") Signed-off-by:

commit a04e54f2 upstream. The following fixes a divide by zero OOPs with TYPE_TAPE due to pscsi_tape_read_blocksize() failing causing a zero sd->sector_size being propigated up via dev_attrib.hw_block_size. It also fixes another long-standing bug where TYPE_TAPE and TYPE_MEDIMUM_CHANGER where using pscsi_create_type_other(), which does not call scsi_device_get() to take the device reference. Instead, rename pscsi_create_type_rom() to pscsi_create_type_nondisk() and use it for all cases. Finally, also drop a dump_stack() in pscsi_get_blocks() for non TYPE_DISK, which in modern target-core can get invoked via target_sense_desc_format() during CHECK_CONDITION.
