由 Jesper Dangaard Brouer 提交于
Florian Weimer seems to have a glibc test-case which requires that loopback interfaces does not get ICMP ratelimited. This was broken by commit c0303efe ("net: reduce cycles spend on ICMP replies that gets rate limited"). An ICMP response will usually be routed back-out the same incoming interface. Thus, take advantage of this and skip global ICMP ratelimit when the incoming device is loopback. In the unlikely event that the outgoing it not loopback, due to strange routing policy rules, ICMP rate limiting still works via peer ratelimiting via icmpv4_xrlim_allow(). Thus, we should still comply with RFC1812 (section 4.3.2.8 "Rate Limiting"). This seems to fix the reproducer given by Florian. While still avoiding to perform expensive and unneeded outgoing route lookup for rate limited packets (in the non-loopback case).

Laura reported a sleep-in-atomic kernel warning inside tcf_act_police_init() which calls gen_replace_estimator() with spinlock protection. It is not necessary in this case, we already have RTNL lock here so it is enough to protect concurrent writers. For the reader, i.e. tcf_act_police(), it needs to make decision based on this rate estimator, in the worst case we drop more/less packets than necessary while changing the rate in parallel, it is still acceptable.

mac80211 allows to modify the SMPS state of an AP both, when it is started, and after it has been started. Such a change will trigger an action frame to all the peers that are currently connected, and will be remembered so that new peers will get notified as soon as they connect (since the SMPS setting in the beacon may not be the right one). This means that we need to remember the SMPS state currently requested as well as the SMPS state that was configured initially (and advertised in the beacon). The former is bss->req_smps and the latter is sdata->smps_mode. Initially, the AP interface could only be started with SMPS_OFF, which means that sdata->smps_mode was SMPS_OFF always. Later, a nl80211 API was added to be able to start an AP with a different AP mode. That code forgot to update bss->req_smps and because of that, if the AP interface was started with SMPS_DYNAMIC, we had: sdata->smps_mode = SMPS_DYNAMIC bss->req_smps = SMPS_OFF That configuration made mac80211 think it needs to fire off an action frame to any new station connecting to the AP in order to let it know that the actual SMPS configuration is SMPS_OFF. Fix that by properly setting bss->req_smps in ieee80211_start_ap.

When mac80211 changes the channel, it also calls into the driver's bss_info_changed() callback, e.g. with BSS_CHANGED_IDLE. The driver may, like iwlwifi does, access more data from bss_info in that case and iwlwifi accesses the basic_rates bitmap, but if changing from a band with more (basic) rates to one with fewer, an out-of-bounds access of the rate array may result. While we can't avoid having invalid data at some point in time, we can avoid having it while we call the driver - so set up all the data before configuring the channel, and then apply it afterwards.

由 Jacob Keller 提交于
A recent commit to refactor the driver and remove the hw_disabled_flags field accidentally introduced two regressions. First, we overwrote pf->flags which removed various key flags including the MSI-X settings. Additionally, it was intended that we have now two flags, HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done, and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere. This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely updates pf->flags instead of overwriting it. Without this patch we will have many problems including disabling MSI-X support, and we'll attempt to use HW ATR eviction on devices which do not support it.

This patch fixes two issues: 1) When forwarding on *,G mroutes that are in a vrf, the kernel was dropping information about the actual incoming interface when calling ip_mr_forward from ip_mr_input. This caused ip_mr_forward to send the multicast packet back out the incoming interface. Fix this by modifying ip_mr_forward to be handed the correctly resolved dev. 2) When a unresolved cache entry is created we store the incoming skb on the unresolved cache entry and upon mroute resolution from the user space daemon, we attempt to forward the packet. Again we were not resolving to the correct incoming device for a vrf scenario, before calling ip_mr_forward. Fix this by resolving to the correct interface and calling ip_mr_forward with the result.

For the rare case where the device runs out of free rx buffer descriptors (in case of pressure on kernel memory), and the napi handler continuously fail to refill new Rx descriptors until device rx queue totally runs out of all free rx buffers to post incoming packet, leading to a deadlock: * The device won't send interrupts since all the new Rx packets will be dropped. * The napi handler won't try to allocate new Rx descriptors since allocation is part of NAPI that's not being invoked any more The fix involves detecting this scenario and rescheduling NAPI (to refill buffers) by the keepalive/watchdog task.

Bug: "Completion context is occupied" error printout will be noticed in dmesg. This error will cause the admin command to fail, which will lead to an ena_probe() failure or a watchdog reset (depends on which admin command failed). Root cause: __ena_com_submit_admin_cmd() is the function that submits new entries to the admin queue. The function have a check that makes sure the queue is not full and the function does not override any outstanding command. It uses head and tail indexes for this check. The head is increased by ena_com_handle_admin_completion() which runs from interrupt context, and the tail index is increased by the submit function (the function is running under ->q_lock, so there is no risk of multithread increment). Each command is associated with a completion context. This context allocated before call to __ena_com_submit_admin_cmd() and freed by ena_com_wait_and_process_admin_cq_interrupts(), right after the command was completed. This can lead to a state where the head was increased, the check passed, but the completion context is still in use. Solution: Use the atomic variable ->outstanding_cmds instead of using the head and the tail indexes. This variable is safe for use since it is bumped in get_comp_ctx() in __ena_com_submit_admin_cmd() and is freed by comp_ctxt_release() Fixes: 1738cd3e ("Add a driver for Amazon Elastic Network Adapters (ENA)") Signed-off-by: NNetanel Belgazal <netanel@amazon.com> Signed-off-by: NDavid S.

DIM (Dynamically-tuned Interrupt Moderation) is a mechanism designed for changing the channel interrupt moderation values in order to reduce CPU overhead for all traffic types. Each iteration of the algorithm, DIM calculates the difference in throughput, packet rate and interrupt rate from last iteration in order to make a decision. DIM relies on counters for each metric. When these counters get to their type's max value they wraparound. In this case the delta between 'end' and 'start' samples is negative and when translated to unsigned integers - very high. This results in a false indication to the algorithm and might result in a wrong decision. The fix calculates the 'distance' between 'end' and 'start' samples in a cyclic way around the relevant type's max value. It can also be viewed as an absolute value around the type's max value instead of around 0. Testing show higher stability in DIM profile selection and no wraparound issues.
