2023-03-16iavf: fix inverted Rx hash condition leading to disabled hashAlexander Lobakin
Condition, which checks whether the netdev has hashing enabled is inverted. Basically, the tagged commit effectively disabled passing flow hash from descriptor to skb, unless user *disables* it via Ethtool. Commit a876c3ba59a6 ("i40e/i40evf: properly report Rx packet hash") fixed this problem, but only for i40e. Invert the condition now in iavf and unblock passing hash to skbs again.

2023-03-16fbdev: Use of_property_present() for testing DT property presenceRob Herring
It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

2023-03-16ata: pata_parport: fix memory leaksOndrej Zary
When ida_alloc() fails, "pi" is not freed although the misleading comment says otherwise. Move the ida_alloc() call up so we really don't have to free "pi" in case of ida_alloc() failure. Also move ida_free() call from pi_remove_one() to pata_parport_dev_release(). It was dereferencing already freed dev pointer. Testing revealed leak even in non-failure case which was tracked down to missing put_device() call after bus_find_device_by_name(). As a result, pata_parport_dev_release() was never called.

2023-03-15veth: Fix use after free in XDP_REDIRECTShawn Bohrer
Commit 718a18a0c8a6 ("veth: Rework veth_xdp_rcv_skb in order to accept non-linear skb") introduced a bug where it tried to use pskb_expand_head() if the headroom was less than XDP_PACKET_HEADROOM. This however uses kmalloc to expand the head, which will later allow consume_skb() to free the skb while is it still in use by AF_XDP. Previously if the headroom was less than XDP_PACKET_HEADROOM we continued on to allocate a new skb from pages so this restores that behavior.

2023-03-15net/mlx5e: Lower maximum allowed MTU in XSK to match XDP prerequisitesAdham Faris
XSK redirecting XDP programs require linearity, hence applies restrictions on the MTU. For PAGE_SIZE=4K, MTU shouldn't exceed 3498. Features that contradict with XDP such HW-LRO and HW-GRO are enforced by the driver in advance, during XSK params validation, except for MTU, which was not enforced before this patch. This has been spotted during test scenario described below: Attaching xdpsock program (PAGE_SIZE=4K), with MTU < 3498, detaching XDP program, changing the MTU to arbitrary value in the range [3499, 3754], attaching XDP program again, which ended up with failure since MTU is > 3498. This commit lowers the XSK MTU limitation to be aligned with XDP MTU limitation, since XSK socket is meaningless without XDP program.

2023-03-15net/mlx5e: Fix cleanup null-ptr deref on encap lockPaul Blakey
During module is unloaded while a peer tc flow is still offloaded, first the peer uplink rep profile is changed to a nic profile, and so neigh encap lock is destroyed. Next during unload, the VF reps netdevs are unregistered which causes the original non-peer tc flow to be deleted, which deletes the peer flow. The peer flow deletion detaches the encap entry and try to take the already destroyed encap lock, causing the below trace. Fix this by clearing peer flows during tc eswitch cleanup (mlx5e_tc_esw_cleanup()).

In few cases, rules with mirror use case are split to two FTEs, one which do the mirror action and forward to second FTE which do the rest of the rule actions and the second redirect action. In case of mirror rules which do split and forward to ovs internal port or VF stack devices, source port rewrite should be used in the second FTE but it is wrongly also set in the first FTE which break the offload. Fix this issue by removing the wrong check if source port rewrite is needed to be used on the first FTE of the split and instead return EOPNOTSUPP which will block offload of rules which mirror to ovs internal port or VF stack devices which isn't supported.

2023-03-15nvme-tcp: fix opcode reporting in the timeout handlerSagi Grimberg
For non in-capsule writes we reuse the request pdu space for a h2cdata pdu in order to avoid over allocating space (either preallocate or dynamically upon receving an r2t pdu). However if the request times out the core expects to find the opcode in the start of the request, which we override. In order to prevent that, without sacrificing additional 24 bytes per request, we just use the tail of the command pdu space instead (last 24 bytes from the 72 bytes command pdu). That should make the command opcode always available, and we get away from allocating more space. If in the future we would need the last 24 bytes of the nvme command available we would need to allocate a dedicated space for it in the request, but until then we can avoid doing so.
