[ Upstream commit be9d3988 ] Currently, we're calling musb_start() twice for DRD ports in some situations. This has been observed to cause enumeration issues after suspend/resume cycles with AM335x. In order to fix the problem, we just have to fix the check on musb_has_gadget() so that it only returns true if current mode is Host and ignore the fact that we have or not a gadget driver loaded.

[ Upstream commit aebda618 ] This fixes an issue introduced in commit b23c8439 (usb: dwc3: gadget: fix DEPSTARTCFG for non-EP0 EPs) that made sure we would only use DEPSTARTCFG once per SetConfig. The trick is that we should use one DEPSTARTCFG per SetConfig *OR* SetInterface. SetInterface was completely missed from the original patch. This problem became aparent after commit 76e838c9 (usb: dwc3: gadget: return error if command sent to DEPCMD register fails) added checking of the return status of device endpoint commands. 'Set Endpoint Transfer Resource' command was caught failing occasionally. This is because the Transfer Resource Index was not getting reset during a SET_INTERFACE request. Finally, to fix the issue, was we have to do is make sure that our start_config_issued flag gets reset whenever we receive a SetInterface request. To verify the problem (and its fix), all we have to do is run test 9 from testusb with 'testusb -t 9 -s 2048 -a -c 5000'. Tested-by:

[ Upstream commit d531be2c ] I have a ST4000DM000 disk. If Linux is booted while the disk is spun down, the command that sets transfer mode causes the disk to spin up. The spin-up takes longer than the default 5s timeout, so the command fails and timeout is reported. Fix this by increasing the timeout to 15s, which is enough for the disk to spin up. Signed-off-by:

[ Upstream commit d6f123a9 ] Currently the check in ext4_ind_migrate() is not enough before doing the real conversion: a) delayed allocated extents could bypass the check on eh->eh_entries and eh->eh_depth This can be demonstrated by this script xfs_io -fc "pwrite 0 4k" -c "pwrite 8k 4k" /mnt/ext4/testfile chattr -e /mnt/ext4/testfile where testfile has two extents but still be converted to non-extent based file format. b) only extent length is checked but not the offset, which would result in data lose (delalloc) or fs corruption (nodelalloc), because non-extent based file only supports at most (12 + 2^10 + 2^20 + 2^30) blocks This can be demostrated by xfs_io -fc "pwrite 5T 4k" /mnt/ext4/testfile chattr -e /mnt/ext4/testfile sync If delalloc is enabled, dmesg prints EXT4-fs warning (device dm-4): ext4_block_to_path:105: block 1342177280 > max in inode 53 EXT4-fs (dm-4): Delayed block allocation failed for inode 53 at logical offset 1342177280 with max blocks 1 with error 5 EXT4-fs (dm-4): This should not happen!!

[ Upstream commit 9705acd6 ] On delalloc enabled file system on invalidatepage operation in ext4_da_page_release_reservation() we want to clear the delayed buffer and remove the extent covering the delayed buffer from the extent status tree. However currently there is a bug where on the systems with page size > block size we will always remove extents from the start of the page regardless where the actual delayed buffers are positioned in the page. This leads to the errors like this: EXT4-fs warning (device loop0): ext4_da_release_space:1225: ext4_da_release_space: ino 13, to_free 1 with only 0 reserved data blocks This however can cause data loss on writeback time if the file system is in ENOSPC condition because we're releasing reservation for someones else delayed buffer. Fix this by only removing extents that corresponds to the part of the page we want to invalidate. This problem is reproducible by the following fio receipt (however I was only able to reproduce it with fio-2.1 or older.

[ Upstream commit db0e2aa47f0a45fc56592c25ad370f8836cbb128 ] Hypercalls submitted by user space tools via the privcmd driver can take a long time (potentially many 10s of seconds) if the hypercall has many sub-operations. A fully preemptible kernel may deschedule such as task in any upcall called from a hypercall continuation. However, in a kernel with voluntary or no preemption, hypercall continuations in Xen allow event handlers to be run but the task issuing the hypercall will not be descheduled until the hypercall is complete and the ioctl returns to user space. These long running tasks may also trigger the kernel's soft lockup detection. Add xen_preemptible_hcall_begin() and xen_preemptible_hcall_end() to bracket hypercalls that may be preempted. Use these in the privcmd driver. When returning from an upcall, call xen_maybe_preempt_hcall() which adds a schedule point if if the current task was within a preemptible hypercall. Since _cond_resched() can move the task to a different CPU, clear and set xen_in_preemptible_hcall around the call. Signed-off-by:

The commit 984ff7a3 is an upstream backport. In fact, it depends on commit 395eea6c ("rtnetlink: delay RTM_DELLINK notification until after ndo_uninit()") which has not been backported in 3.18.y. Before commit 395eea6c, rollback_registered_many() uses rtmsg_ifinfo(). The call to this function is done with dev->reg_state set to NETREG_UNREGISTERING, thus testing this reg_state in rtmsg_ifinfo() is wrong. This patch partially reverts commit 984ff7a3.

[ Upstream commit 514d748f ] Commit e4502c63 (ufs: deal with nfsd/iget races) made ufs create inodes with I_NEW flag set. However ufs_mkdir() never cleared this flag. Thus if someone ever tried to lookup the directory by inode number, he would deadlock waiting for I_NEW to be cleared. Luckily this mostly happens only if the filesystem is exported over NFS since otherwise we have the inode attached to dentry and don't look it up by inode number. In rare cases dentry can get freed without inode being freed and then we'd hit the deadlock even without NFS export. Fix the problem by clearing I_NEW before instantiating new directory inode.

[ Upstream commit 431dae77 ] Eric noticed problems with vhost-scsi and virtio-ccw: vhost-scsi complained about overwriting values in the config space, which was triggered by a broken implementation of virtio-ccw's config get/set routines. It was probably sheer luck that we did not hit this before. When writing a value to the config space, the WRITE_CONF ccw will always write from the beginning of the config space up to and including the value to be set. If the config space up to the value has not yet been retrieved from the device, however, we'll end up overwriting values. Keep track of the known config space and update if needed to avoid this. Moreover, READ_CONF will only read the number of bytes it has been instructed to retrieve, so we must not copy more than that to the buffer, or we might overwrite trailing values. Reported-by:

[ Upstream commit 9fc2b4b4 ] 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".

Currently, even if a hypervisor advertises support for architectural performance monitoring version 1, perf may still try to use the fixed counters, as the constraints are set up based on the CPU model.

Don't we need to ensure that we have "synchronize" _between_ list_del() and list_add() ? IOW. Suppose that ring_buffer_attach() preempts right_after get_state_synchronize_rcu() and gp completes before spin_lock(). In this case cond_synchronize_rcu() does nothing and we reuse ->rb_entry without waiting for gp in between? It also moves the ->rcu_pending check under "if (rb)", to make it more readable imo.

[ Upstream commit 85e84ba3 ] 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.
