2023-09-13wifi: cfg80211: call reg_call_notifier on beacon hintsAbhishek Kumar1-0/+3
Currently the channel property updates are not propagated to driver. This causes issues in the discovery of hidden SSIDs and fails to connect to them. This change defines a new wiphy flag which when enabled by vendor driver, the reg_call_notifier callback will be trigger on beacon hints. This ensures that the channel property changes are visible to the vendor driver. The vendor changes the channels for active scans. This fixes the discovery issue of hidden SSID.

Add a new flag 'update' which is set to true during start_ap() if (and only if) one of the following two conditions are met: - Userspace passed an empty nested attribute which indicates that the feature should be disabled and templates deleted. - Userspace passed all the parameters for the nested attribute. Existing configuration will not be changed while the flag remains false. Add similar changes for unsolicited broadcast probe response transmission.

2023-09-13tcp: Fix bind() regression for v4-mapped-v6 wildcard address.Kuniyuki Iwashima1-0/+5
Andrei Vagin reported bind() regression with strace logs. If we bind() a TCPv6 socket to ::FFFF:0.0.0.0 and then bind() a TCPv4 socket to 127.0.0.1, the 2nd bind() should fail but now succeeds. from socket import * s1 = socket(AF_INET6, SOCK_STREAM) s1.bind(('::ffff:0.0.0.0', 0)) s2 = socket(AF_INET, SOCK_STREAM) s2.bind(('127.0.0.1', s1.getsockname()[1])) During the 2nd bind(), if tb->family is AF_INET6 and sk->sk_family is AF_INET in inet_bind2_bucket_match_addr_any(), we still need to check if tb has the v4-mapped-v6 wildcard address. The example above does not work after commit 5456262d2baa ("net: Fix incorrect address comparison when searching for a bind2 bucket"), but the blamed change is not the commit. Before the commit, the leading zeros of ::FFFF:0.0.0.0 were treated as 0.0.0.0, and the sequence above worked by chance. Technically, this case has been broken since bhash2 was introduced. Note that if we bind() two sockets to 127.0.0.1 and then ::FFFF:0.0.0.0, the 2nd bind() fails properly because we fall back to using bhash to detect conflicts for the v4-mapped-v6 address.

2023-09-12tcp: defer regular ACK while processing socket backlogEric Dumazet1-0/+1
This idea came after a particular workload requested the quickack attribute set on routes, and a performance drop was noticed for large bulk transfers. For high throughput flows, it is best to use one cpu running the user thread issuing socket system calls, and a separate cpu to process incoming packets from BH context. (With TSO/GRO, bottleneck is usually the 'user' cpu) Problem is the user thread can spend a lot of time while holding the socket lock, forcing BH handler to queue most of incoming packets in the socket backlog. Whenever the user thread releases the socket lock, it must first process all accumulated packets in the backlog, potentially adding latency spikes. Due to flood mitigation, having too many packets in the backlog increases chance of unexpected drops. Backlog processing unfortunately shifts a fair amount of cpu cycles from the BH cpu to the 'user' cpu, thus reducing max throughput. This patch takes advantage of the backlog processing, and the fact that ACK are mostly cumulative. The idea is to detect we are in the backlog processing and defer all eligible ACK into a single one, sent from tcp_release_cb(). This saves cpu cycles on both sides, and network resources. Performance of a single TCP flow on a 200Gbit NIC: - Throughput is increased by 20% (100Gbit -> 120Gbit). - Number of generated ACK per second shrinks from 240,000 to 40,000. - Number of backlog drops per second shrinks from 230 to 0. Benchmark context: - Regular netperf TCP_STREAM (no zerocopy) - Intel(R) Xeon(R) Platinum 8481C (Saphire Rapids) - MAX_SKB_FRAGS = 17 (~60KB per GRO packet) This feature is guarded by a new sysctl, and enabled by default: /proc/sys/net/ipv4/tcp_backlog_ack_defer Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Yuchung Cheng <ycheng@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Acked-by: Dave Taht <dave.taht@gmail.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

Since commit 1202cdd66531("Remove DECnet support from kernel") has been merged, all callers pass in the initial_ref value of 1 when they call dst_alloc(). Therefore, remove initial_ref when the dst_alloc() is declared and replace initial_ref with 1 in dst_alloc(). Also when all callers call dst_init(), the value of initial_ref is 1. Therefore, remove the input parameter initial_ref of the dst_init() and replace initial_ref with the value 1 in dst_init.

2023-09-11wifi: cfg80211: fix cqm_config access raceJohannes Berg1-1/+2
Max Schulze reports crashes with brcmfmac. The reason seems to be a race between userspace removing the CQM config and the driver calling cfg80211_cqm_rssi_notify(), where if the data is freed while cfg80211_cqm_rssi_notify() runs it will crash since it assumes wdev->cqm_config is set. This can't be fixed with a simple non-NULL check since there's nothing we can do for locking easily, so use RCU instead to protect the pointer, but that requires pulling the updates out into an asynchronous worker so they can sleep and call back into the driver. Since we need to change the free anyway, also change it to go back to the old settings if changing the settings fails.

2023-09-11wifi: cfg80211/mac80211: hold link BSSes when assoc fails for MLO connectionWen Gong1-1/+1
When connect to MLO AP with more than one link, and the assoc response of AP is not success, then cfg80211_unhold_bss() is not called for all the links' cfg80211_bss except the primary link which means the link used by the latest successful association request. Thus the hold value of the cfg80211_bss is not reset to 0 after the assoc fail, and then the __cfg80211_unlink_bss() will not be called for the cfg80211_bss by __cfg80211_bss_expire(). Then the AP always looks exist even the AP is shutdown or reconfigured to another type, then it will lead error while connecting it again. The detail info are as below. When connect with muti-links AP, cfg80211_hold_bss() is called by cfg80211_mlme_assoc() for each cfg80211_bss of all the links. When assoc response from AP is not success(such as status_code==1), the ieee80211_link_data of non-primary link(sdata->link[link_id]) is NULL because ieee80211_assoc_success()->ieee80211_vif_update_links() is not called for the links. Then struct cfg80211_rx_assoc_resp resp in cfg80211_rx_assoc_resp() and struct cfg80211_connect_resp_params cr in __cfg80211_connect_result() will only have the data of the primary link, and finally function cfg80211_connect_result_release_bsses() only call cfg80211_unhold_bss() for the primary link. Then cfg80211_bss of the other links will never free because its hold is always > 0 now. Hence assign value for the bss and status from assoc_data since it is valid for this case. Also assign value of addr from assoc_data when the link is NULL because the addrs of assoc_data and link both represent the local link addr and they are same value for success connection.

2023-09-01ipv4: ignore dst hint for multipath routesSriram Yagnaraman1-0/+1
Route hints when the nexthop is part of a multipath group causes packets in the same receive batch to be sent to the same nexthop irrespective of the multipath hash of the packet. So, do not extract route hint for packets whose destination is part of a multipath group. A new SKB flag IPSKB_MULTIPATH is introduced for this purpose, set the flag when route is looked up in ip_mkroute_input() and use it in ip_extract_route_hint() to check for the existence of the flag.

git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull sysctl updates from Luis Chamberlain: "Long ago we set out to remove the kitchen sink on kernel/sysctl.c arrays and placings sysctls to their own sybsystem or file to help avoid merge conflicts. Matthew Wilcox pointed out though that if we're going to do that we might as well also *save* space while at it and try to remove the extra last sysctl entry added at the end of each array, a sentintel, instead of bloating the kernel by adding a new sentinel with each array moved. Doing that was not so trivial, and has required slowing down the moves of kernel/sysctl.c arrays and measuring the impact on size by each new move. The complex part of the effort to help reduce the size of each sysctl is being done by the patient work of el señor Don Joel Granados. A lot of this is truly painful code refactoring and testing and then trying to measure the savings of each move and removing the sentinels. Although Joel already has code which does most of this work, experience with sysctl moves in the past shows is we need to be careful due to the slew of odd build failures that are possible due to the amount of random Kconfig options sysctls use. To that end Joel's work is split by first addressing the major housekeeping needed to remove the sentinels, which is part of this merge request. The rest of the work to actually remove the sentinels will be done later in future kernel releases. The preliminary math is showing this will all help reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array where we are able to remove each sentinel in the future. That also means there is no more bloating the kernel with the extra ~64 bytes per array moved as no new sentinels are created" * tag 'sysctl-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: sysctl: Use ctl_table_size as stopping criteria for list macro sysctl: SIZE_MAX->ARRAY_SIZE in register_net_sysctl vrf: Update to register_net_sysctl_sz networking: Update to register_net_sysctl_sz netfilter: Update to register_net_sysctl_sz ax.25: Update to register_net_sysctl_sz sysctl: Add size to register_net_sysctl function sysctl: Add size arg to __register_sysctl_init sysctl: Add size to register_sysctl sysctl: Add a size arg to __register_sysctl_table sysctl: Add size argument to init_header sysctl: Add ctl_table_size to ctl_table_header sysctl: Use ctl_table_header in list_for_each_table_entry sysctl: Prefer ctl_table_header in proc_sysctl
