b7363e6 Sagi Grimberg 08 March 2017, 20:03:17 UTC IB/device: Convert ib-comp-wq to be CPU-bound This workqueue is used by our storage target mode ULPs via the new CQ API. Recent observations when working with very high-end flash storage devices reveal that UNBOUND workqueue threads can migrate between cpu cores and even numa nodes (although some numa locality is accounted for). While this attribute can be useful in some workloads, it does not fit in very nicely with the normal run-to-completion model we usually use in our target-mode ULPs and the block-mq irq<->cpu affinity facilities. The whole block-mq concept is that the completion will land on the same cpu where the submission was performed. The fact that our submitter thread is migrating cpus can break this locality. We assume that as a target mode ULP, we will serve multiple initiators/clients and we can spread the load enough without having to use unbound kworkers. Also, while we're at it, expose this workqueue via sysfs which is harmless and can be useful for debug.

9fcd67d David Marchand 24 February 2017, 14:38:26 UTC IB/rxe: increment msn only when completing a request According to C9-147, MSN should only be incremented when the last packet of a multi packet request has been received. "Logically, the requester associates a sequential Send Sequence Number (SSN) with each WQE posted to the send queue. The SSN bears a one- to-one relationship to the MSN returned by the responder in each re- sponse packet. Therefore, when the requester receives a response, it in- terprets the MSN as representing the SSN of the most recent request completed by the responder to determine which send WQE(s) can be completed."

This creates a situation where all virtual mappings of the same physical page share the same virtual cache index and guarantees VIPT coherence. Otherwise the cache is non-coherent and the kernel will not see writes by userspace when reading the shared page (or vice-versa).

We have not seen problems with this change in the lab, so fingers crossed.

Specifics: - Make intel_pstate use one set of global P-state limits in the active mode regardless of the scaling_governor settings for individual CPUs instead of switching back and forth between two of them in a way that is hard to control (Rafael Wysocki). - Drop a useless function from intel_pstate to prevent it from modifying the maximum supported frequency value unexpectedly which may confuse the cpufreq core (Rafael Wysocki). - Fix the cpufreq core to restore policy limits on CPU online so that the limits are not reset over system suspend/resume, among other things (Viresh Kumar). - Fix the initialization of the schedutil cpufreq governor to make the IO-wait boosting mechanism in it actually work on systems with one CPU per cpufreq policy (Rafael Wysocki). - Add a sanity check to the cpuidle core to prevent crashes from happening if the architecture code initialization fails to set up things as expected (Vaidyanathan Srinivasan)" * tag 'pm-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: Restore policy min/max limits on CPU online cpuidle: Validate cpu_dev in cpuidle_add_sysfs() cpufreq: intel_pstate: Fix policy data management in passive mode cpufreq: schedutil: Fix per-CPU structure initialization in sugov_start() cpufreq: intel_pstate: One set of global limits in active mode 24 March 2017, 03:00:39 UTC

1914f0c Ankur Arora 21 March 2017, 22:43:38 UTC xen/acpi: upload PM state from init-domain to Xen This was broken in commit cd979883b9ed ("xen/acpi-processor: fix enabling interrupts on syscore_resume"). do_suspend (from xen/manage.c) and thus xen_resume_notifier never get called on the initial-domain at resume (it is if running as guest.) The rationale for the breaking change was that upload_pm_data() potentially does blocking work in syscore_resume(). This patch addresses the original issue by scheduling upload_pm_data() to execute in workqueue context.

That can happen when Intel host controllers wait for the present state to propagate. The spin lock is not necessary here. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. Although the spin lock probably should be removed from the code paths that lead to this point, such a patch would touch too much code to be suitable for stable trees.

Patch fixes the problem and avoid confusion in the future just decrease n counter when ctrl_fill_info() fail. User visible problem caused by this bug is failure to get access to some genetlink family i.e. nl80211. However problem is reproducible only if number of registered genetlink families is big enough to cause second call of ctrl_dumpfamily().

a97e50c Daniel Borkmann 22 March 2017, 12:08:08 UTC socket, bpf: fix sk_filter use after free in sk_clone_lock In sk_clone_lock(), we create a new socket and inherit most of the parent's members via sock_copy() which memcpy()'s various sections. Now, in case the parent socket had a BPF socket filter attached, then newsk->sk_filter points to the same instance as the original sk->sk_filter. sk_filter_charge() is then called on the newsk->sk_filter to take a reference and should that fail due to hitting max optmem, we bail out and release the newsk instance. The issue is that commit 278571baca2a ("net: filter: simplify socket charging") wrongly combined the dismantle path with the failure path of xfrm_sk_clone_policy(). This means, even when charging failed, we call sk_free_unlock_clone() on the newsk, which then still points to the same sk_filter as the original sk. Thus, sk_free_unlock_clone() calls into __sk_destruct() eventually where it tests for present sk_filter and calls sk_filter_uncharge() on it, which potentially lets sk_omem_alloc wrap around and releases the eBPF prog and sk_filter structure from the (still intact) parent. Fix it by making sure that when sk_filter_charge() failed, we reset newsk->sk_filter back to NULL before passing to sk_free_unlock_clone(), so that we don't mess with the parents sk_filter. Only if xfrm_sk_clone_policy() fails, we did reach the point where either the parent's filter was NULL and as a result newsk's as well or where we previously had a successful sk_filter_charge(), thus for that case, we do need sk_filter_uncharge() to release the prior taken reference on sk_filter.

8c290e6 Alexei Starovoitov 22 March 2017, 02:05:04 UTC bpf: fix hashmap extra_elems logic In both kmalloc and prealloc mode the bpf_map_update_elem() is using per-cpu extra_elems to do atomic update when the map is full. There are two issues with it. The logic can be misused, since it allows max_entries+num_cpus elements to be present in the map. And alloc_extra_elems() at map creation time can fail percpu alloc for large map values with a warn: WARNING: CPU: 3 PID: 2752 at ../mm/percpu.c:892 pcpu_alloc+0x119/0xa60 illegal size (32824) or align (8) for percpu allocation The fixes for both of these issues are different for kmalloc and prealloc modes. For prealloc mode allocate extra num_possible_cpus elements and store their pointers into extra_elems array instead of actual elements. Hence we can use these hidden(spare) elements not only when the map is full but during bpf_map_update_elem() that replaces existing element too. That also improves performance, since pcpu_freelist_pop/push is avoided. Unfortunately this approach cannot be used for kmalloc mode which needs to kfree elements after rcu grace period. Therefore switch it back to normal kmalloc even when full and old element exists like it was prior to commit 6c9059817432 ("bpf: pre-allocate hash map elements"). Add tests to check for over max_entries and large map values.

31739ea Doug Berger 21 March 2017, 21:01:06 UTC net: bcmgenet: remove bcmgenet_internal_phy_setup() Commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset") removed the bcmgenet_mii_reset() function from bcmgenet_power_up() and bcmgenet_internal_phy_setup() functions. In so doing it broke the reset of the internal PHY devices used by the GENETv1-GENETv3 which required this reset before the UniMAC was enabled. It also broke the internal GPHY devices used by the GENETv4 because the config_init that installed the AFE workaround was no longer occurring after the reset of the GPHY performed by bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). In addition the code in bcmgenet_internal_phy_setup() related to the "enable APD" comment goes with the bcmgenet_mii_reset() so it should have also been removed. Commit bd4060a6108b ("net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up()") moved the bcmgenet_phy_power_set() call to the bcmgenet_power_up() function, but failed to remove it from the bcmgenet_internal_phy_setup() function. Had it done so, the bcmgenet_internal_phy_setup() function would have been empty and could have been removed at that time. Commit 5dbebbb44a6a ("net: bcmgenet: Software reset EPHY after power on") was submitted to correct the functional problems introduced by commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset"). It was included in v4.4 and made available on 4.3-stable. Unfortunately, it didn't fully revert the commit because this bcmgenet_mii_reset() doesn't apply the soft reset to the internal GPHY used by GENETv4 like the previous one did. This prevents the restoration of the AFE work- arounds for internal GPHY devices after the bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). This commit takes the alternate approach of removing the unnecessary bcmgenet_internal_phy_setup() function which shouldn't have been in v4.3 so that when bcmgenet_mii_reset() was restored it should have only gone into bcmgenet_power_up(). This will avoid the problems while also removing the redundancy (and hopefully some of the confusion).

1ad9a00 Paul Blakey 21 March 2017, 13:59:16 UTC net/mlx5e: Avoid supporting udp tunnel port ndo for VF reps This was added to allow the TC offloading code to identify offloading encap/decap vxlan rules. The VF reps are effectively related to the same mlx5 PCI device as the PF. Since the kernel invokes the (say) delete ndo for each netdev, the FW erred on multiple vxlan dst port deletes when the port was deleted from the system. We fix that by keeping the registration to be carried out only by the PF. Since the PF serves as the uplink device, the VF reps will look up a port there and realize if they are ok to offload that. Tested: <SETUP VFS> <SETUP switchdev mode to have representors> ip link add vxlan1 type vxlan id 44 dev ens5f0 dstport 9999 ip link set vxlan1 up ip link del dev vxlan1 Fixes: 4a25730eb202 ('net/mlx5e: Add ndo_udp_tunnel_add to VF representors') Signed-off-by: Paul Blakey <paulb@mellanox.com> Reviewed-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

E.g. set policy L4, add some L4 rules, set policy to L2 --> bad! Hence we disallow it. Keep track of how many offloaded rules are now set and refuse inline mode changes if this isn't zero.
