2018-01-05ACPICA: Debugger: fix slight indentation issueErik Schmauss1-1/+1
ACPICA commit c75af007d35c0afe8791ac39b7749c7442f49912 The %*s format specifier prints a string with a width indicated by an integer. In the case of acpi_os_printf() ("%*s", acpi_gbl_nesting_level, " "), a single space is printed to the console when acpi_gbl_nesting_level is 0 or 1. This change increments acpi_gbl_nesting_level so that there is one space printed when acpi_gbl_nesting_level is 0 and two spaces printed when acpi_gbl_nesting_level is 1.

2017-11-27ACPICA: iASL: change processing of external op namespace nodes for correctnessErik Schmauss2-6/+8
ACPICA commit aa866a9b4f24bbec9f158d10325b486d7d12d90f The declaration External (ABCD.EFGH) creates two nodes in the namespace: ABCD and EFGH where ABCD is marked as an implicit external node. ABCD is labeled as implicit because there does not exist a specific External (ABCD) declaration. Before this change, the declaration External (ABCD.EFGH) and External (ABCD.EFGH.IJKL) creates the namespace nodes ABCD, EFGH, and IJKL where ABCD and EFGH are labeled as implicit external nodes. This is incorrect. The only implicit node should be ABCD because EFGH and IJKL are explicit nodes. This change fixes the labeling procecess of external op namespace nodes so that nodes are properly labeled as implicit external. Due to this commit, the below ASL code results in a compilation error. definition_block ("DSDT.aml", "DSDT", 0x02, "INTEL", "BDW ", 0x0) { External(\_SB.PCI0.GFX0, device_obj) External(\_SB.PCI0.GFX0.ALSI) Scope(\_SB) { Device(PCI0) { Device(GFX0) { Name(_ADR, 0x00020000) } } } } Link: https://github.com/acpica/acpica/commit/aa866a9b Signed-off-by: Erik Schmauss <erik.schmauss@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Rafael J.

2017-11-27ACPICA: Dispatcher: Introduce timeout mechanism for infinite loop detectionLv Zheng3-9/+10
ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9 This patch implements a new infinite loop detection mechanism to replace the old one, it uses acpi_os_get_timer() to limit loop execution into a determined time slice. This is useful in case some hardware/firmware operations really require the AML interpreter to wait while the old mechanism could expire too fast on recent machines. The new mechanism converts old acpi_gbl_max_loop_iterations to store the user configurable value for the new mechanism in order to allow users to be still able to configure this value for acpiexec via command line. This patch also removes wrong initilization code of acpi_gbl_max_loop_iterations accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the default value is also properly tuned for acpiexec).

2017-11-27ACPICA: Avoid null pointer dereference on Op.Colin Ian King1-3/+3
ACPICA commit 08a00639b0d6756e8ba1421419fc3728904651d9 The calls to acpi_os_acquire_object can result in a null being assigned to Op (for example if a mutex acquire fails) which can lead to a null pointer dereference on Op on the call to ASL_CV_TRANSFER_COMMENTS (via function cv_transfer_comments). Move the block into the previous block that checks for a null Op so that we never can call cv_transfer_comments with a null Op.

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 <davem@davemloft.net>
2017-11-23net: 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.")
