The iwlmei driver breaks iwlwifi when returning from suspend. The interface ends up in the 'down' state after coming back from suspend. And iwd doesn't touch the interface state, but wpa_supplicant does, so the bug only happens on iwd. The bug report[0] has been open for four months now, and no fix seems to be forthcoming. Since just disabling the iwlmei driver works as a workaround, let's mark the config option as broken until it can be fixed properly.

I get a log line like this every 4 seconds when connected to my AP: [15650.221468] iwlwifi 0000:09:00.0: Got NSS = 4 - trimming to 2 Looking at the code, this seems to be related to a hardware limitation, and there's nothing to be done. In an effort to keep my dmesg manageable, downgrade this error to "debug" rather than "info". Cc: Johannes Berg <johannes.berg@intel.com> Signed-off-by:

In case of drv own fail in reset, we may need to run mac_reset several times. The sequence would trigger system crash as the log below. Because we do not re-enable/schedule "tx_napi" before disable it again, the process would keep waiting for state change in napi_diable().

When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll function immediately returns an error. This is incorrect for two reasons: * the function terminates without enabling interrupts or scheduling NAPI, * the error code (-ENOMEM) is returned instead of the number of received packets. After the first memory allocation failure occurs, packet reception is locked due to disabled interrupts from DMA..

This is a follow-up to the discussion in [0]. It seems to me that at least the IP version used on Amlogic SoC's sometimes has a problem if register MAC_CTRL_REG is written whilst the chip is still processing a previous write. But that's just a guess. Adding a delay between two writes to this register helps, but we can also simply omit the offending second write. This patch uses the second approach and is based on a suggestion from Qi Duan. Benefit of this approach is that we can save few register writes, also on not affected chip versions.

In looping on FW update tests we occasionally see the FW_ACTIVATE_STATUS command fail while it is in its EAGAIN loop waiting for the FW activate step to finsh inside the FW. The firmware is complaining that the done bit is set when a new dev_cmd is going to be processed. Doing a clean on the cmd registers and doorbell before exiting the wait-for-done and cleaning the done bit before the sleep prevents this from occurring.

There is a case found in heavy testing where a link flap happens just before a firmware Recovery event and the driver gets stuck in the BROKEN state. This comes from the driver getting interrupted by a FW generation change when coming back up from the link flap, and the call to ionic_start_queues() in ionic_link_status_check() fails. This can be addressed by having the fw_up code clear the BROKEN bit if seen, rather than waiting for a user to manually force the interface down and then back up.

Fix three bugs in the rxrpc's sendmsg implementation: (1) rxrpc_new_client_call() should release the socket lock when returning an error from rxrpc_get_call_slot(). (2) rxrpc_wait_for_tx_window_intr() will return without the call mutex held in the event that we're interrupted by a signal whilst waiting for tx space on the socket or relocking the call mutex afterwards. Fix this by: (a) moving the unlock/lock of the call mutex up to rxrpc_send_data() such that the lock is not held around all of rxrpc_wait_for_tx_window*() and (b) indicating to higher callers whether we're return with the lock dropped. Note that this means recvmsg() will not block on this call whilst we're waiting. (3) After dropping and regaining the call mutex, rxrpc_send_data() needs to go and recheck the state of the tx_pending buffer and the tx_total_len check in case we raced with another sendmsg() on the same call. Thinking on this some more, it might make sense to have different locks for sendmsg() and recvmsg(). There's probably no need to make recvmsg() wait for sendmsg(). It does mean that recvmsg() can return MSG_EOR indicating that a call is dead before a sendmsg() to that call returns - but that can currently happen anyway. Without fix (2), something like the following can be induced: WARNING: bad unlock balance detected! 5.16.0-rc6-syzkaller #0 Not tainted ------------------------------------- syz-executor011/3597 is trying to release lock (&call->user_mutex) at: [<ffffffff885163a3>] rxrpc_do_sendmsg+0xc13/0x1350 net/rxrpc/sendmsg.c:748 but there are no more locks to release! other info that might help us debug this: no locks held by syz-executor011/3597. ...

When we are not connected to a channel, sending channel "switch" announcement doesn't make any sense. The BSS list is empty in that case. This causes the for loop in cfg80211_get_bss() to be bypassed, so the function returns NULL (check line 1424 of net/wireless/scan.c), causing the WARN_ON() in ieee80211_ibss_csa_beacon() to get triggered (check line 500 of net/mac80211/ibss.c), which was consequently reported on the syzkaller dashboard. Thus, check if we have an existing connection before generating the CSA beacon in ieee80211_ibss_finish_csa().

ieee80211_scan_rx() tries to access scan_req->flags after a null check, but a UAF is observed when the scan is completed and __ieee80211_scan_completed() executes, which then calls cfg80211_scan_done() leading to the freeing of scan_req. Since scan_req is rcu_dereference()'d, prevent the racing in __ieee80211_scan_completed() by ensuring that from mac80211's POV it is no longer accessed from an RCU read critical section before we call cfg80211_scan_done().

Pablo Neira Ayuso says: ==================== Netfilter fixes for net 1) Fix crash with malformed ebtables blob which do not provide all entry points, from Florian Westphal. 2) Fix possible TCP connection clogging up with default 5-days timeout in conntrack, from Florian. 3) Fix crash in nf_tables tproxy with unsupported chains, also from Florian. 4) Do not allow to update implicit chains. 5) Make table handle allocation per-netns to fix data race. 6) Do not truncated payload length and offset, and checksum offset. Instead report EINVAl. 7) Enable chain stats update via static key iff no error occurs. 8) Restrict osf expression to ip, ip6 and inet families. 9) Restrict tunnel expression to netdev family. 10) Fix crash when trying to bind again an already bound chain. 11) Flowtable garbage collector might leave behind pending work to delete entries. This patch comes with a previous preparation patch as dependency. 12) Allow net.netfilter.nf_conntrack_frag6_high_thresh to be lowered, from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_defrag_ipv6: allow nf_conntrack_frag6_high_thresh increases netfilter: flowtable: fix stuck flows on cleanup due to pending work netfilter: flowtable: add function to invoke garbage collection immediately netfilter: nf_tables: disallow binding to already bound chain netfilter: nft_tunnel: restrict it to netdev family netfilter: nft_osf: restrict osf to ipv4, ipv6 and inet families netfilter: nf_tables: do not leave chain stats enabled on error netfilter: nft_payload: do not truncate csum_offset and csum_type netfilter: nft_payload: report ERANGE for too long offset and length netfilter: nf_tables: make table handle allocation per-netns friendly netfilter: nf_tables: disallow updates of implicit chain netfilter: nft_tproxy: restrict to prerouting hook netfilter: conntrack: work around exceeded receive window netfilter: ebtables: reject blobs that don't provide all entry points ==================== Link: https://lore.kernel.org/r/20220824220330.64283-1-pablo@netfilter.orgSigned-off-by: -

Commit c078290a ("selftests: include bonding tests into the kselftest infra") adds the bonding tests in the directory: tools/testing/selftests/drivers/net/bonding/ The file entry in MAINTAINERS for the BONDING DRIVER however refers to: tools/testing/selftests/net/bonding/ Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken file pattern. Repair this file entry in BONDING DRIVER. Signed-off-by:

It was not possible to create 1-tuple flow director rule for IPv6 flow type. It was caused by incorrectly checking for source IP address when validating user provided destination IP address. Fix this by changing ip6src to correct ip6dst address in destination IP address validation for IPv6 flow type. Fixes: efca91e8 ("i40e: Add flow director support for IPv6") Signed-off-by:

The ixgbe_ptp_start_cyclecounter is intended to be called whenever the cyclecounter parameters need to be changed. Since commit a9763f3c ("ixgbe: Update PTP to support X550EM_x devices"), this function has cleared the SYSTIME registers and reset the TSAUXC DISABLE_SYSTIME bit. While these need to be cleared during ixgbe_ptp_reset, it is wrong to clear them during ixgbe_ptp_start_cyclecounter. This function may be called during both reset and link status change. When link changes, the SYSTIME counter is still operating normally, but the cyclecounter should be updated to account for the possibly changed parameters. Clearing SYSTIME when link changes causes the timecounter to jump because the cycle counter now reads zero. Extract the SYSTIME initialization out to a new function and call this during ixgbe_ptp_reset. This prevents the timecounter adjustment and avoids an unnecessary reset of the current time. This also restores the original SYSTIME clearing that occurred during ixgbe_ptp_reset before the commit above. Reported-by:
