2017-11-25net: thunderbolt: Stop using zero to mean no valid DMA mappingMika Westerberg1-33/+24
Commit 86dabda426ac ("net: thunderbolt: Clear finished Tx frame bus address in tbnet_tx_callback()") fixed a DMA-API violation where the driver called dma_unmap_page() in tbnet_free_buffers() for a bus address that might already be unmapped. The fix was to zero out the bus address of a frame in tbnet_tx_callback(). However, as pointed out by David Miller, zero might well be valid mapping (at least in theory) so it is not good idea to use it here. It turns out that we don't need the whole map/unmap dance for Tx buffers at all. Instead we can map the buffers when they are initially allocated and unmap them when the interface is brought down. In between we just DMA sync the buffers for the CPU or device as needed. Signed-off-by: Mika Westerberg <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2017-11-25net: thunderx: Fix TCP/UDP checksum offload for IPv6 pktsSunil Goutham1-1/+0
Don't offload IP header checksum to NIC. This fixes a previous patch which enabled checksum offloading for both IPv4 and IPv6 packets. So L3 checksum offload was getting enabled for IPv6 pkts. And HW is dropping these pkts as it assumes the pkt is IPv4 when IP csum offload is set in the SQ descriptor.

git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending 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.

2017-11-24bcache: recover data from backing when data is cleanRui Hua1-7/+6
When we send a read request and hit the clean data in cache device, there is a situation called cache read race in bcache(see the commit in the tail of cache_look_up(), the following explaination just copy from there): The bucket we're reading from might be reused while our bio is in flight, and we could then end up reading the wrong data. We guard against this by checking (in bch_cache_read_endio()) if the pointer is stale again; if so, we treat it as an error (s->iop.error = -EINTR) and reread from the backing device (but we don't pass that error up anywhere) It should be noted that cache read race happened under normal circumstances, not the circumstance when SSD failed, it was counted and shown in /sys/fs/bcache/XXX/internal/cache_read_races. Without this patch, when we use writeback mode, we will never reread from the backing device when cache read race happened, until the whole cache device is clean, because the condition (s->recoverable && (dc && !atomic_read(&dc->has_dirty))) is false in cached_dev_read_error(). In this situation, the s->iop.error(= -EINTR) will be passed up, at last, user will receive -EINTR when it's bio end, this is not suitable, and wield to up-application. In this patch, we use s->read_dirty_data to judge whether the read request hit dirty data in cache device, it is safe to reread data from the backing device when the read request hit clean data. This can not only handle cache read race, but also recover data when failed read request from cache device.

2017-11-24bcache: add a comment in journal bucket readingTang Junhui1-0/+5
Journal bucket is a circular buffer, the bucket can be like YYYNNNYY, which means the first valid journal in the 7th bucket, and the latest valid journal in third bucket, in this case, if we do not try we the zero index first, We may get a valid journal in the 7th bucket, then we call find_next_bit(bitmap,ca->sb.njournal_buckets, l + 1) to get the first invalid bucket after the 7th bucket, because all these buckets is valid, so no bit 1 in bitmap, thus find_next_bit() function would return with ca->sb.njournal_buckets (8). So, after that, bcache only read journal in 7th and 8the bucket, the first to the third buckets are lost. So, it is important to let developer know that, we need to try the zero index at first in the hash-search, and avoid any breaks in future's code modification.

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: David 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: David S. Miller <[email protected]>
2017-11-24net: accept UFO datagrams from tuntap and packetWillem de Bruijn2-1/+3
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 182e0b6b5846~1..d9d30adf5677. 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 939912216fa8 ("net: skb_needs_check() removes CHECKSUM_UNNECESSARY check for tx.") and reverting commit 8d63bee643f1 ("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: fb652fdfe837 ("macvlan/macvtap: Remove NETIF_F_UFO advertisement.")
