Some servers return inode number zero for the root directory, which causes ls to display incorrect data (missing "." and ".."). If the server returns zero for the inode number of the root directory, fake an inode number for it.

During transport reconnect, other processes may have registered memory and blocked on transport. This creates a deadlock situation because the transport resources can't be freed, and reconnect is blocked. Fix this by returning to upper layer on timeout. Before returning, transport status is set to reconnecting so other processes will release memory registration resources. Upper layer will retry the reconnect. This is not in fast I/O path so setting the timeout to 5 seconds.

Donald reported that IPv6 route leaking between VRFs is not working. The root cause is the strict argument in the call to rt6_lookup when validating the nexthop spec. ip6_route_check_nh validates the gateway and device (if given) of a route spec. It in turn could call rt6_lookup (e.g., lookup in a given table did not succeed so it falls back to a full lookup) and if so sets the strict argument to 1. That means if the egress device is given, the route lookup needs to return a result with the same device. This strict requirement does not work with VRFs (IPv4 or IPv6) because the oif in the flow struct is overridden with the index of the VRF device to trigger a match on the l3mdev rule and force the lookup to its table. The right long term solution is to add an l3mdev index to the flow struct such that the oif is not overridden. That solution will not backport well, so this patch aims for a simpler solution to relax the strict argument if the route spec device is an l3mdev slave. As done in other places, use the FLOWI_FLAG_SKIP_NH_OIF to know that the RT6_LOOKUP_F_IFACE flag needs to be removed.

In some situation vlan packets do not have ethernet headers. One example is packets from tun devices. Users can specify vlan protocol in tun_pi field instead of IP protocol. When we have a vlan device with reorder_hdr disabled on top of the tun device, such packets from tun devices are untagged in skb_vlan_untag() and vlan headers will be inserted back in vlan_insert_inner_tag(). vlan_insert_inner_tag() however did not expect packets without ethernet headers, so in such a case size argument for memmove() underflowed. We don't need to copy headers for packets which do not have preceding headers of vlan headers, so skip memmove() in that case. Also don't write vlan protocol in skb->data when it does not have enough room for it.

If a page is already locked, attempting to dirty it leads to a deadlock in lock_page(). This is what currently happens to ITER_BVEC pages when a dio-enabled loop device is backed by ceph: $ losetup --direct-io /dev/loop0 /mnt/cephfs/img $ xfs_io -c 'pread 0 4k' /dev/loop0 Follow other file systems and only dirty ITER_IOVEC pages.
