The L3 error will be generated and system will crash during unloading of CPSW driver if CPSW is used as module and ethX devices are down. This happens because CPSW can be power off by PM runtime now when ethX devices are down. Hence, ensure that CPSW powered up by PM runtime before performing any deinitialization actions which require CPSW registers access. In case of PM runtime error just leave cpsw_remove() as we can't do anything anymore.

Fix deadlock in cpdma_ctlr_destroy() which is triggered now on cpsw module removal: cpsw_remove() - cpdma_ctlr_destroy() - spin_lock_irqsave(&ctlr->lock, flags) - cpdma_ctlr_stop() - spin_lock_irqsave(&ctlr->lock, flags); - cpdma_chan_destroy() - spin_lock_irqsave(&ctlr->lock, flags); The issue has not been observed before because CPDMA channels have been destroyed manually by CPSW until commit d941ebe8 ("net: ethernet: ti: cpsw: use destroy ctlr to destroy channels") was merged.

The commit 637d3e99 ("cxgb4: Discard the packet if the length is greater than mtu") introduced a regression in the VLAN interface performance when Tx VLAN offload is disabled. Check if skb is tagged, regardless of whether it is hardware accelerated or not. Presently we were checking only for hardware acclereated one, which caused performance to drop to ~0.17Mbps on a 10GbE adapter for VLAN interface, when tx vlan offload is turned off using ethtool. The ethernet head length calculation was going wrong in this case, and driver ended up dropping packets.

Each PF/VF has a limited number of vlan filters for configuration purposes; This information is passed to qede and is used to prevent over-usage - once a vlan is to be configured and no filter credit is available, the driver would switch into working in vlan-promisc mode. Problem is the credit pool is shared by both PFs and VFs, and currently PFs aren't deducting the filters that are reserved for their VFs from their quota, which may lead to some vlan filters failing unknowingly due to lack of credit.

As part of ndo_vlan_rx_kill_vid() implementation, qede is requesting firmware to remove the vlan filter. This currently happens even if the vlan wasn't previously added [In case device ran out of vlan credits]. For PFs this doesn't cause any issues as the firmware would simply ignore the removal request. But for VFs their parent PF is holding an accounting of the configured vlans, and such a request would cause the PF to fail the VF's removal request. Simply fix this for both PFs & VFs and don't remove filters that were not previously added.

Pull userns vfs updates from Eric Biederman: "This tree contains some very long awaited work on generalizing the user namespace support for mounting filesystems to include filesystems with a backing store. The real world target is fuse but the goal is to update the vfs to allow any filesystem to be supported. This patchset is based on a lot of code review and testing to approach that goal. While looking at what is needed to support the fuse filesystem it became clear that there were things like xattrs for security modules that needed special treatment. That the resolution of those concerns would not be fuse specific. That sorting out these general issues made most sense at the generic level, where the right people could be drawn into the conversation, and the issues could be solved for everyone. At a high level what this patchset does a couple of simple things: - Add a user namespace owner (s_user_ns) to struct super_block. - Teach the vfs to handle filesystem uids and gids not mapping into to kuids and kgids and being reported as INVALID_UID and INVALID_GID in vfs data structures. By assigning a user namespace owner filesystems that are mounted with only user namespace privilege can be detected. This allows security modules and the like to know which mounts may not be trusted. This also allows the set of uids and gids that are communicated to the filesystem to be capped at the set of kuids and kgids that are in the owning user namespace of the filesystem. One of the crazier corner casees this handles is the case of inodes whose i_uid or i_gid are not mapped into the vfs. Most of the code simply doesn't care but it is easy to confuse the inode writeback path so no operation that could cause an inode write-back is permitted for such inodes (aka only reads are allowed). This set of changes starts out by cleaning up the code paths involved in user namespace permirted mounts. Then when things are clean enough adds code that cleanly sets s_user_ns. Then additional restrictions are added that are possible now that the filesystem superblock contains owner information. These changes should not affect anyone in practice, but there are some parts of these restrictions that are changes in behavior. - Andy's restriction on suid executables that does not honor the suid bit when the path is from another mount namespace (think /proc/[pid]/fd/) or when the filesystem was mounted by a less privileged user. - The replacement of the user namespace implicit setting of MNT_NODEV with implicitly setting SB_I_NODEV on the filesystem superblock instead. Using SB_I_NODEV is a stronger form that happens to make this state user invisible. The user visibility can be managed but it caused problems when it was introduced from applications reasonably expecting mount flags to be what they were set to. There is a little bit of work remaining before it is safe to support mounting filesystems with backing store in user namespaces, beyond what is in this set of changes. - Verifying the mounter has permission to read/write the block device during mount. - Teaching the integrity modules IMA and EVM to handle filesystems mounted with only user namespace root and to reduce trust in their security xattrs accordingly. - Capturing the mounters credentials and using that for permission checks in d_automount and the like. (Given that overlayfs already does this, and we need the work in d_automount it make sense to generalize this case). Furthermore there are a few changes that are on the wishlist: - Get all filesystems supporting posix acls using the generic posix acls so that posix_acl_fix_xattr_from_user and posix_acl_fix_xattr_to_user may be removed. [Maintainability] - Reducing the permission checks in places such as remount to allow the superblock owner to perform them. - Allowing the superblock owner to chown files with unmapped uids and gids to something that is mapped so the files may be treated normally. I am not considering even obvious relaxations of permission checks until it is clear there are no more corner cases that need to be locked down and handled generically.

This reverts commit 3c9fe8cd. As Miklos points out in commit c1b2cc1a, the "lookup_hash()" helper is now unused, and in fact, with the hash salting changes, since the hash of a dentry name now depends on the directory dentry it is in, the helper function isn't even really likely to be useful. So rather than keep it around in case somebody else might end up finding a use for it, let's just remove the helper and not trick people into thinking it might be a useful thing. For example, I had obviously completely missed how the helper didn't follow the normal dentry hashing patterns, and how the hash salting patch broke overlayfs. Things would quietly build and look sane, but not work. Suggested-by: NMiklos Szeredi <mszeredi@redhat.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

We have to do this directly after fuse_sync_writes() Signed-off-by: NAlexey Kuznetsov <kuznet@virtuozzo.com> Signed-off-by: NMaxim Patlasov <mpatlasov@virtuozzo.com> Signed-off-by: NMiklos Szeredi <mszeredi@redhat.com> Fixes: 4d99ff8f ("fuse: Turn writeback cache on") Cc: <stable@vger.kernel.org> # v3.15+

In kernel bug 150021, a kernel panic was reported when restoring a hibernate image. Only a picture of the oops was reported, so I can't paste the whole thing here. But here are the most interesting parts: kernel tried to execute NX-protected page - exploit attempt? (uid: 0) BUG: unable to handle kernel paging request at ffff8804615cfd78 ... RIP: ffff8804615cfd78 RSP: ffff8804615f0000 RBP: ffff8804615cfdc0 ... Call Trace: do_signal+0x23 exit_to_usermode_loop+0x64 ... The RIP is on the same page as RBP, so it apparently started executing on the stack. The bug was bisected to commit ef0f3ed5 (x86/asm/power: Create stack frames in hibernate_asm_64.S), which in retrospect seems quite dangerous, since that code saves and restores the stack pointer from a global variable ('saved_context'). There are a lot of moving parts in the hibernate save and restore paths, so I don't know exactly what caused the panic. Presumably, a FRAME_END was executed without the corresponding FRAME_BEGIN, or vice versa. That would corrupt the return address on the stack and would be consistent with the details of the above panic. [ rjw: One major problem is that by the time the FRAME_BEGIN in restore_registers() is executed, the stack pointer value may not be valid any more. Namely, the stack area pointed to by it previously may have been overwritten by some image memory contents and that page frame may now be used for whatever different purpose it had been allocated for before hibernation. In that case, the FRAME_BEGIN will corrupt that memory. ] Instead of doing the frame pointer save/restore around the bounds of the affected functions, just do it around the call to swsusp_save(). That has the same effect of ensuring that if swsusp_save() sleeps, the frame pointers will be correct. It's also a much more obviously safe way to do it than the original patch. And objtool still doesn't report any warnings.

The empty checking logic is duplicated in ovl_check_empty_and_clear() and ovl_remove_and_whiteout(), except the condition for clearing whiteouts is different: ovl_check_empty_and_clear() checked for being upper ovl_remove_and_whiteout() checked for merge OR lower Move the intersection of those checks (upper AND merge) into ovl_check_empty_and_clear() and simplify ovl_remove_and_whiteout().
