commit 4c86d777 upstream. On IPv4-mapped IPv6 addresses sk_family is AF_INET6, but the flow informations are created based on AF_INET. So the routing set up 'struct flowi4' but we try to access 'struct flowi6' what leads to an out of bounds access. Fix this by using the family we get with the dst_entry, like we do it for the standard policy lookup. Reported-by:

[ Upstream commit 07485918 ] Currently, the sched:sched_switch tracepoint reports deadline tasks with priority -1. But when reading the trace via perf script I've got the following output: # ./d & # (d is a deadline task, see [1]) # perf record -e sched:sched_switch -a sleep 1 # perf script ... swapper 0 [000] 2146.962441: sched:sched_switch: swapper/0:0 [120] R ==> d:2593 [4294967295] d 2593 [000] 2146.972472: sched:sched_switch: d:2593 [4294967295] R ==> g:2590 [4294967295] The task d reports the wrong priority [4294967295]. This happens because the "int prio" is stored in an unsigned long long val. Although it is set as a %lld, as int is shorter than unsigned long long, trace_seq_printf prints it as a positive number. The fix is just to cast the val as an int, and print it as a %d, as in the sched:sched_switch tracepoint's "format". The output with the fix is: # ./d & # perf record -e sched:sched_switch -a sleep 1 # perf script ... swapper 0 [000] 4306.374037: sched:sched_switch: swapper/0:0 [120] R ==> d:10941 [-1] d 10941 [000] 4306.383823: sched:sched_switch: d:10941 [-1] R ==> swapper/0:0 [120] [1] d.c --- #include <stdio.h> #include <unistd.h> #include <sys/syscall.h> #include <linux/types.h> #include <linux/sched.h> struct sched_attr { __u32 size, sched_policy; __u64 sched_flags; __s32 sched_nice; __u32 sched_priority; __u64 sched_runtime, sched_deadline, sched_period; }; int sched_setattr(pid_t pid, const struct sched_attr *attr, unsigned int flags) { return syscall(__NR_sched_setattr, pid, attr, flags); } int main(void) { struct sched_attr attr = { .size = sizeof(attr), .sched_policy = SCHED_DEADLINE, /* This creates a 10ms/30ms reservation */ .sched_runtime = 10 * 1000 * 1000, .sched_period = attr.sched_deadline = 30 * 1000 * 1000, }; if (sched_setattr(0, &attr, 0) < 0) { perror("sched_setattr"); return -1; } for(;;); } --- Committer notes: Got the program from the provided URL, http://bristot.me/lkml/d.c, trimmed it and included in the cset log above, so that we have everything needed to test it in one place.

[ Upstream commit c2931667 ] Currently how btrfs dio deals with split dio write is not good enough if dio write is split into several segments due to the lack of contiguous space, a large dio write like 'dd bs=1G count=1' can end up with incorrect outstanding_extents counter and endio would complain loudly with an assertion. This fixes the problem by compensating the outstanding_extents counter in inode if a large dio write gets split. Reported-by:

[ Upstream commit 096de2f8 ] When VXLAN offloading is enabled, be_features_check() tries to check if an encapsulated packet is indeed a VXLAN packet. The check is not strict enough, and considers any UDP-encapsulated ethernet frame with a 8-byte tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE have a 8-byte header, so they get through this check. Force the UDP destination port to be the one that has been offloaded to hardware. Without this, GENEVE-encapsulated packets can end up having an incorrect checksum when both a GENEVE and a VXLAN (offloaded) tunnel are configured. This is similar to commit a547224d ("mlx4e: Do not attempt to offload VXLAN ports that are unrecognized"). Signed-off-by:

[ Upstream commit c2a6bbaf ] The way acpi_find_child_device() works currently is that, if there are two (or more) devices with the same _ADR value in the same namespace scope (which is not specifically allowed by the spec and the OS behavior in that case is not defined), the first one of them found to be present (with the help of _STA) will be returned. This covers the majority of cases, but is not sufficient if some of the devices in question have a _HID (or _CID) returning some valid ACPI/PNP device IDs (which is disallowed by the spec) and the ASL writers' expectation appears to be that the OS will match devices without a valid ACPI/PNP device ID against a given bus address first. To cover this special case as well, modify find_child_checks() to prefer devices without ACPI/PNP device IDs over devices that have them. Suggested-by:

[ Upstream commit 1f2ed153 ] Since 'perf probe' supports cross-arch probes, it is possible to analyze different arch kernel image which has different bits-per-long. In that case, it fails to get the module name because it uses the MOD_NAME_OFFSET macro based on the host machine bits-per-long, instead of the target arch bits-per-long. This fixes above issue by changing modname-offset based on the target archs bit width. This is ok because linux kernel uses LP64 model on 64bit arch. E.g. without this (on x86_64, and target module is arm32): $ perf probe -m build-arm/fs/configfs/configfs.ko -D configfs_lookup p:probe/configfs_lookup :configfs_lookup+0 ^-Here is an empty module name. With this fix, you can see correct module name: $ perf probe -m build-arm/fs/configfs/configfs.ko -D configfs_lookup p:probe/configfs_lookup configfs:configfs_lookup+0 Signed-off-by:

[ Upstream commit 2f884e6e ] The below call chain generates "scheduling while atomic" backtrace and causes system crash when Keystone 2 IRQ chip driver is used with RT-kernel: gic_handle_irq() |-__handle_domain_irq() |-generic_handle_irq() |-keystone_irq_handler() |-regmap_read() |-regmap_lock_spinlock() |-rt_spin_lock() The reason is that Keystone driver dispatches IRQ using chained IRQ handler and accesses I/O memory through syscon->regmap(mmio) which is implemented as fast_io regmap and uses regular spinlocks for synchronization, but spinlocks transformed to rt_mutexes on RT. Hence, convert Keystone 2 IRQ driver to use generic irq handler instead of chained IRQ handler. This way it will be compatible with RT kernel where it will be forced thread IRQ handler while in non-RT kernel it still will be executed in HW IRQ context.

[ Upstream commit 88b333b0 ] Currently the value written to CP_RB_WPTR is calculated on the fly as (rb->next - rb->start). But as the code is designed rb->next is wrapped before writing the commands so if a series of commands happened to fit perfectly in the ringbuffer, rb->next would end up being equal to rb->size / 4 and thus result in an out of bounds address to CP_RB_WPTR. The easiest way to fix this is to mask WPTR when writing it to the hardware; it makes the hardware happy and the rest of the ringbuffer math appears to work and there isn't any point in upsetting anything.

[ Upstream commit 10b1c04e ] Demoting simple flow steering rule priority (for DPDK) was achieved by wrapping FW commands MLX4_QP_FLOW_STEERING_ATTACH/DETACH for the PF as well, and forcing the priority to MLX4_DOMAIN_NIC in the wrapper function for the PF and all VFs. In function mlx4_ib_create_flow(), this change caused the main rule creation for the PF to be wrapped, while it left the associated tunnel steering rule creation unwrapped for the PF. This mismatch caused rule deletion failures in mlx4_ib_destroy_flow() for the PF when the detach wrapper function did not find the associated tunnel-steering rule (since creation of that rule for the PF did not go through the wrapper function). Fix this by setting MLX4_QP_FLOW_STEERING_ATTACH/DETACH to be "native" (so that the PF invocation does not go through the wrapper), and perform the required priority demotion for the PF in the mlx4_ib_create_flow() code path.

[ Upstream commit 3b01fe7f ] mlx4_QP_FLOW_STEERING_DETACH_wrapper first removes the steering rule (which results in freeing the rule structure), and then references a field in this struct (the qp number) when releasing the busy-status on the rule's qp. Since this memory was freed, it could reallocated and changed. Therefore, the qp number in the struct may be incorrect, so that we are releasing the incorrect qp. This leaves the rule's qp in the busy state (and could possibly release an incorrect qp as well). Fix this by saving the qp number in a local variable, for use after removing the steering rule.

ipv6: Should use consistent conditional judgement for ip6 fragment between __ip6_append_data and ip6_finish_output [ Upstream commit e4c5e13a ] There is an inconsistent conditional judgement between __ip6_append_data and ip6_finish_output functions, the variable length in __ip6_append_data just include the length of application's payload and udp6 header, don't include the length of ipv6 header, but in ip6_finish_output use (skb->len > ip6_skb_dst_mtu(skb)) as judgement, and skb->len include the length of ipv6 header. That causes some particular application's udp6 payloads whose length are between (MTU - IPv6 Header) and MTU were fragmented by ip6_fragment even though the rst->dev support UFO feature. Add the length of ipv6 header to length in __ip6_append_data to keep consistent conditional judgement as ip6_finish_output for ip6 fragment. Signed-off-by:

[ Upstream commit 9da34cd3 ] Under the switchdev/offloads mode, packets that don't match any e-switch steering rule are sent towards the e-switch management port. We use a NIC HW steering rule set per vport (uplink and VFs) to make them be received into the host OS through the respective vport representor netdevice. Currnetly such missed RoCE packets will not get to this NIC steering rule, and hence VF RoCE will not work over the slow path of the offloads mode. This is b/c these packets will be matched by a steering rule added by the firmware that serves RoCE traffic set on the PF NIC vport which is also the e-switch management port under SRIOV. Disabling RoCE on the e-switch management vport when we are in the offloads mode, will signal to the firmware to remove their RoCE rule, and then the missed RoCE packets will be matched by the representor NIC steering rule as any other missed packets. To achieve that, we disable RoCE on the PF vport. We do that by removing (hot-unplugging) the IB device instance associated with the PF. This is also required by our current model where the PF serves as the uplink representor and hence only SW switching (TC, bridge, OVS) applications and slow path vport mlx5e net-device should be running over that vport.
