Pull SCSI target updates from Nicholas Bellinger: "This series is predominantly bug-fixes, with a few small improvements that have been outstanding over the last release cycle. As usual, the associated bug-fixes have CC' tags for stable. Also, things have been particularly quiet wrt new developments the last months, with most folks continuing to focus on stability atop 4.x stable kernels for their respective production configurations. Also at this point, the stable trees have been synced up with mainline. This will continue to be a priority, as production users tend to run exclusively atop stable kernels, a few releases behind mainline. The highlights include: - Fix PR PREEMPT_AND_ABORT null pointer dereference regression in v4.11+ (tangwenji) - Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu) - Add netlink command reply supported option for each device (Kenjiro Nakayama) - cxgbit: Abort the TCP connection in case of data out timeout (Varun Prakash) - Fix PR/ALUA file path truncation (David Disseldorp) - Fix double se_cmd completion during ->cmd_time_out (Mike Christie) - Fix QUEUE_FULL + SCSI task attribute handling in 4.1+ (Bryant Ly + nab) - Fix quiese during transport_write_pending_qf endless loop (nab) - Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK in 3.14+ (Don White + nab)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (35 commits) tcmu: Add a missing unlock on an error path tcmu: Fix some memory corruption iscsi-target: Fix non-immediate TMR reference leak iscsi-target: Make TASK_REASSIGN use proper se_cmd->cmd_kref target: Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK target: Fix quiese during transport_write_pending_qf endless loop target: Fix caw_sem leak in transport_generic_request_failure target: Fix QUEUE_FULL + SCSI task attribute handling iSCSI-target: Use common error handling code in iscsi_decode_text_input() target/iscsi: Detect conn_cmd_list corruption early target/iscsi: Fix a race condition in iscsit_add_reject_from_cmd() target/iscsi: Modify iscsit_do_crypto_hash_buf() prototype target/iscsi: Fix endianness in an error message target/iscsi: Use min() in iscsit_dump_data_payload() instead of open-coding it target/iscsi: Define OFFLOAD_BUF_SIZE once target: Inline transport_put_cmd() target: Suppress gcc 7 fallthrough warnings target: Move a declaration of a global variable into a header file tcmu: fix double se_cmd completion target: return SAM_STAT_TASK_SET_FULL for TCM_OUT_OF_RESOURCES ...

Fix some of dentry handling in AFS directory ops: (1) Do d_drop() on the new_dentry before assigning a new inode to it in afs_vnode_new_inode(). It's fine to do this before calling afs_iget() because the operation has taken place on the server. (2) Replace d_instantiate()/d_rehash() with d_add(). (3) Don't d_drop() the new_dentry in afs_rename() on error. Also fix afs_link() and afs_rename() to call key_put() on all error paths where the key is taken.

Make afs_write_begin() wait for a page that's marked PG_writeback because: (1) We need to avoid interference with the data being stored so that the data on the server ends up in a defined state. (2) page->private is used to track the window of dirty data within a page, but it's also used by the storage code to track what's being written, being cleared by the completion notification. Ownership can't be relinquished by the storage code until completion because it a store fails, the data must be remarked dirty.

In the function ipvlan_get_L3_hdr, current codes use pskb_may_pull to make sure the skb header has enough linear room for ipv6 header. But it would use the latter memory directly without linear check when it is icmp. So it still may access the unepxected memory in ipvlan_addr_lookup. Now invoke the pskb_may_pull again if it is ipv6 icmp. Signed-off-by: NGao Feng <gfree.wind@vip.163.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

So it still may access the unepxected memory. Now use arp_hdr_len(port->dev) instead of the arp header as the param. Signed-off-by: NGao Feng <gfree.wind@vip.163.com> Signed-off-by: NDavid S.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Fixes 2017-11-21 This series contains fixes for igb/vf, ixgbe/vf, i40e/vf and fm10k. Jake fixes a regression issue with older firmware, where we were using the NVM lock to synchronize NVM reads for all devices and firmware versions, yet this caused issues with older firmware prior to version 1.5. Fixed this by only grabbing the lock for newer devices and firmware version 1.5 or newer. Zijie Pan fixes the calculation of the i40e VF MAC addresses, where it was possible to increment to the next MAC entry without calling i40e_add_mac_filter(). Amritha removes the upper limit of 64 queues on a channel VSI since the upper bound is determined by the VSI's num_queue_pairs. Filip fixes an issue during FLR resets, where should have been checking for upcoming core reset and if so, just return with I40E_ERR_NOT_READY. Alan fixes the notifying clients of l2 parameters by copying the parameters to the client instance struct and re-organizes the priority in which the client tasks fire so that if the flag for notifying l2 params is set, it will trigger before the client open task. Also fixed the promiscuous settings after reset for all the VSI's. Brian King from IBM fixes an issue seen on Power systems which would result in skb list corruption and eventual kernel oops. Brian provides the same fix for nearly all our drivers, to replace the read_barrier_depends with smp_rmb() to ensure loads are ordered with respect to the load of tx_buffer->next_to_watch. ==================== Signed-off-by: NDavid S.

Daniel Borkmann says: ==================== pull-request: bpf 2017-11-23 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Several BPF offloading fixes, from Jakub. Among others: - Limit offload to cls_bpf and XDP program types only. - Move device validation into the driver and don't make any assumptions about the device in the classifier due to shared blocks semantics. - Don't pass offloaded XDP program into the driver when it should be run in native XDP instead. Offloaded ones are not JITed for the host in such cases. - Don't destroy device offload state when moved to another namespace. - Revert dumping offload info into user space for now, since ifindex alone is not sufficient. This will be redone properly for bpf-next tree. 2) Fix test_verifier to avoid using bpf_probe_write_user() helper in test cases, since it's dumping a warning into kernel log which may confuse users when only running tests. Switch to use bpf_trace_printk() instead, from Yonghong. 3) Several fixes for correcting ARG_CONST_SIZE_OR_ZERO semantics before it becomes uabi, from Gianluca. More specifically: - Add a type ARG_PTR_TO_MEM_OR_NULL that is used only by bpf_csum_diff(), where the argument is either a valid pointer or NULL. The subsequent ARG_CONST_SIZE_OR_ZERO then enforces a valid pointer in case of non-0 size or a valid pointer or NULL in case of size 0. Given that, the semantics for ARG_PTR_TO_MEM in combination with ARG_CONST_SIZE_OR_ZERO are now such that in case of size 0, the pointer must always be valid and cannot be NULL. This fix in semantics allows for bpf_probe_read() to drop the recently added size == 0 check in the helper that would become part of uabi otherwise once released. At the same time we can then fix bpf_probe_read_str() and bpf_perf_event_output() to use ARG_CONST_SIZE_OR_ZERO instead of ARG_CONST_SIZE in order to fix recently reported issues by Arnaldo et al, where LLVM optimizes two boundary checks into a single one for unknown variables where the verifier looses track of the variable bounds and thus rejects valid programs otherwise. 4) A fix for the verifier for the case when it detects comparison of two constants where the branch is guaranteed to not be taken at runtime. Verifier will rightfully prune the exploration of such paths, but we still pass the program to JITs, where they would complain about using reserved fields, etc. Track such dead instructions and sanitize them with mov r0,r0. Rejection is not possible since LLVM may generate them for valid C code and doesn't do as much data flow analysis as verifier. For bpf-next we might implement removal of such dead code and adjust branches instead. Fix from Alexei. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Tuntap and similar devices can inject GSO packets. Accept type VIRTIO_NET_HDR_GSO_UDP, even though not generating UFO natively. Processes are expected to use feature negotiation such as TUNSETOFFLOAD to detect supported offload types and refrain from injecting other packets. This process breaks down with live migration: guest kernels do not renegotiate flags, so destination hosts need to expose all features that the source host does. Partially revert the UFO removal from 182e0b6b~1..d9d30adf. This patch introduces nearly(*) no new code to simplify verification. It brings back verbatim tuntap UFO negotiation, VIRTIO_NET_HDR_GSO_UDP insertion and software UFO segmentation. It does not reinstate protocol stack support, hardware offload (NETIF_F_UFO), SKB_GSO_UDP tunneling in SKB_GSO_SOFTWARE or reception of VIRTIO_NET_HDR_GSO_UDP packets in tuntap. To support SKB_GSO_UDP reappearing in the stack, also reinstate logic in act_csum and openvswitch. Achieve equivalence with v4.13 HEAD by squashing in commit 93991221 ("net: skb_needs_check() removes CHECKSUM_UNNECESSARY check for tx.") and reverting commit 8d63bee6 ("net: avoid skb_warn_bad_offload false positives on UFO"). (*) To avoid having to bring back skb_shinfo(skb)->ip6_frag_id, ipv6_proxy_select_ident is changed to return a __be32 and this is assigned directly to the frag_hdr. Also, SKB_GSO_UDP is inserted at the end of the enum to minimize code churn. Tested Booted a v4.13 guest kernel with QEMU. On a host kernel before this patch `ethtool -k eth0` shows UFO disabled. After the patch, it is enabled, same as on a v4.13 host kernel. A UFO packet sent from the guest appears on the tap device: host: nc -l -p -u 8000 & tcpdump -n -i tap0 guest: dd if=/dev/zero of=payload.txt bs=1 count=2000 nc -u 192.16.1.1 8000 < payload.txt Direct tap to tap transmission of VIRTIO_NET_HDR_GSO_UDP succeeds, packets arriving fragmented: ./with_tap_pair.sh ./tap_send_ufo tap0 tap1 (from https://github.com/wdebruij/kerneltools/tree/master/tests) Changes v1 -> v2 - simplified set_offload change (review comment) - documented test procedure Link: http://lkml.kernel.org/r/<CAF=yD-LuUeDuL9YWPJD9ykOZ0QCjNeznPDr6whqZ9NGMNF12Mw@mail.gmail.com> Fixes: fb652fdf ("macvlan/macvtap: Remove NETIF_F_UFO advertisement.")

Commit 6fa1ba61 partially implemented the new ethtool API, by replacing get_settings() with get_link_ksettings(). This breaks ethtool, since the userspace tool (according to the new API specs) never tries the legacy set() call, when the new get() call succeeds. All attempts to chance some setting from userspace result in: > Cannot set new settings: Operation not supported Implement the missing set() call.

Florian reported a breakage with anycast routes due to commit 4832c30d ("net: ipv6: put host and anycast routes on device with address"). Prior to this commit anycast routes were added against the loopback device causing repetitive route entries with no insight into why they existed. e.g.: $ ip -6 ro ls table local type anycast anycast 2001:db8:1:: dev lo proto kernel metric 0 pref medium anycast 2001:db8:2:: dev lo proto kernel metric 0 pref medium anycast fe80:: dev lo proto kernel metric 0 pref medium anycast fe80:: dev lo proto kernel metric 0 pref medium The point of commit 4832c30d is to add the routes using the device with the address which is causing the route to be added. e.g.,: $ ip -6 ro ls table local type anycast anycast 2001:db8:1:: dev eth1 proto kernel metric 0 pref medium anycast 2001:db8:2:: dev eth2 proto kernel metric 0 pref medium anycast fe80:: dev eth2 proto kernel metric 0 pref medium anycast fe80:: dev eth1 proto kernel metric 0 pref medium For traffic to work as it did before, the dst device needs to be switched to the loopback when the copy is created similar to local routes.

Commit 3e034725 ("net/smc: common functions for RMBs and send buffers") merged handling of SMC receive and send buffers. It introduced sk_buf_size as merged start value for size determination. But since sk_buf_size is not used at all, sk_sndbuf is erroneously used as start for rmb creation. This patch makes sure, sk_buf_size is really used as intended, and sk_rcvbuf is used as start value for rmb creation.

When the 'ignore_routes_with_linkdown' sysctl is set, we should not consider linkdown nexthops during route lookup. While the code correctly verifies that the initially selected route ('match') has a carrier, it does not perform the same check in the subsequent multipath selection, resulting in a potential packet loss. In case the chosen route does not have a carrier and the sysctl is set, choose the initially selected route.
