On systems with IMA-appraisal enabled with a policy requiring file signatures, the "good" signature values are stored on the filesystem as extended attributes (security.ima). Signature verification failure would normally be limited to just a particular file (eg. executable), but during boot signature verification failure could result in a system hang. Defining and requiring a new public_key_signature field requires all callers of asymmetric signature verification to be updated to reflect the change. This patch updates the integrity asymmetric_verify() caller.

Commit 07d02a67 causes a use-after free in the RPCSEC_GSS credential destroy code, because the call to get_rpccred() in gss_destroying_context() will now always fail to increment the refcount. While we could just replace the get_rpccred() with a refcount_set(), that would have the unfortunate consequence of resurrecting a credential in the credential cache for which we are in the process of destroying the RPCSEC_GSS context. Rather than do this, we choose to make a copy that is never added to the cache and use that to destroy the context.

Since commit ff17fa56 ("d_invalidate(): unhash immediately") immediately unhashes the dentry, we'll never return the mountpoint in lookup_mountpoint(), which can lead to an unbreakable loop in d_invalidate(). I have reports of NFS clients getting into this condition after the server removes an export of an existing mount created through follow_automount(), but I suspect there are various other ways to produce this problem if we hunt down users of d_invalidate(). For example, it is possible to get into this state by using XFS' d_invalidate() call in xfs_vn_unlink(): truncate -s 100m img{1,2} mkfs.xfs -q -n version=ci img1 mkfs.xfs -q -n version=ci img2 mkdir -p /mnt/xfs mount img1 /mnt/xfs mkdir /mnt/xfs/sub1 mount img2 /mnt/xfs/sub1 cat > /mnt/xfs/sub1/foo & umount -l /mnt/xfs/sub1 mount img2 /mnt/xfs/sub1 mount --make-private /mnt/xfs mkdir /mnt/xfs/sub2 mount --move /mnt/xfs/sub1 /mnt/xfs/sub2 rmdir /mnt/xfs/sub1 Fix this by moving the check for an unlinked dentry out of the detach_mounts() path.

Pull networking fixes from David Miller: "One last pull request before heading to Vancouver for LPC, here we have: 1) Don't forget to free VSI contexts during ice driver unload, from Victor Raj. 2) Don't forget napi delete calls during device remove in ice driver, from Dave Ertman. 3) Don't request VLAN tag insertion of ibmvnic device when SKB doesn't have VLAN tags at all. 4) IPV4 frag handling code has to accomodate the situation where two threads try to insert the same fragment into the hash table at the same time. From Eric Dumazet. 5) Relatedly, don't flow separate on protocol ports for fragmented frames, also from Eric Dumazet. 6) Memory leaks in qed driver, from Denis Bolotin. 7) Correct valid MTU range in smsc95xx driver, from Stefan Wahren. 8) Validate cls_flower nested policies properly, from Jakub Kicinski. 9) Clearing of stats counters in mc88e6xxx driver doesn't retain important bits in the G1_STATS_OP register causing the chip to hang.
