2021-12-14mac80211: do drv_reconfig_complete() before restarting allJohannes Berg
When we reconfigure, the driver might do some things to complete the reconfiguration. It's strange and could be broken in some cases because we restart other works (e.g. remain-on-channel and TX) before this happens, yet only start queues later. Change this to do the reconfig complete when reconfiguration is actually complete, not when we've already started doing other things again. For iwlwifi, this should fix a race where the reconfig can race with TX, for ath10k and ath11k that also use this it won't make a difference because they just start queues there, and mac80211 also stopped the queues and will restart them later as before.

Mark TXQs as having seen transmit while they were stopped if we bail out of drv_wake_tx_queue() due to reconfig, so that the queue wake after this will make them catch up. This is particularly necessary for when TXQs are used for management packets since those TXQs won't see a lot of traffic that'd make them catch up later.

2021-12-14mac80211: agg-tx: don't schedule_and_wake_txq() under sta->lockJohannes Berg
When we call ieee80211_agg_start_txq(), that will in turn call schedule_and_wake_txq(). Called from ieee80211_stop_tx_ba_cb() this is done under sta->lock, which leads to certain circular lock dependencies, as reported by Chris Murphy: https://lore.kernel.org/r/CAJCQCtSXJ5qA4bqSPY=oLRMbv-irihVvP7A2uGutEbXQVkoNaw@mail.gmail.com In general, ieee80211_agg_start_txq() is usually not called with sta->lock held, only in this one place. But it's always called with sta->ampdu_mlme.mtx held, and that's therefore clearly sufficient. Change ieee80211_stop_tx_ba_cb() to also call it without the sta->lock held, by factoring it out of ieee80211_remove_tid_tx() (which is only called in this one place). This breaks the locking chain and makes it less likely that we'll have similar locking chain problems in the future.

2021-12-14mac80211: send ADDBA requests using the tid/queue of the aggregation sessionFelix Fietkau
Sending them out on a different queue can cause a race condition where a number of packets in the queue may be discarded by the receiver, because the ADDBA request is sent too early. This affects any driver with software A-MPDU setup which does not allocate packet seqno in hardware on tx, regardless of whether iTXQ is used or not. The only driver I've seen that explicitly deals with this issue internally is mwl8k.

2021-12-13mptcp: never allow the PM to close a listener subflowPaolo Abeni
Currently, when deleting an endpoint the netlink PM treverses all the local MPTCP sockets, regardless of their status. If an MPTCP listener socket is bound to the IP matching the delete endpoint, the listener TCP socket will be closed. That is unexpected, the PM should only affect data subflows.

2021-12-13fget: clarify and improve __fget_files() implementationLinus Torvalds
Commit 054aa8d439b9 ("fget: check that the fd still exists after getting a ref to it") fixed a race with getting a reference to a file just as it was being closed. It was a fairly minimal patch, and I didn't think re-checking the file pointer lookup would be a measurable overhead, since it was all right there and cached. But I was wrong, as pointed out by the kernel test robot. The 'poll2' case of the will-it-scale.per_thread_ops benchmark regressed quite noticeably. Admittedly it seems to be a very artificial test: doing "poll()" system calls on regular files in a very tight loop in multiple threads. That means that basically all the time is spent just looking up file descriptors without ever doing anything useful with them (not that doing 'poll()' on a regular file is useful to begin with). And as a result it shows the extra "re-check fd" cost as a sore thumb. Happily, the regression is fixable by just writing the code to loook up the fd to be better and clearer. There's still a cost to verify the file pointer, but now it's basically in the noise even for that benchmark that does nothing else - and the code is more understandable and has better comments too. [ Side note: this patch is also a classic case of one that looks very messy with the default greedy Myers diff - it's much more legible with either the patience of histogram diff algorithm ] Link: https://lore.kernel.org/lkml/20211210053743.GA36420@xsang-OptiPlex-9020/ Link: https://lore.kernel.org/lkml/20211213083154.GA20853@linux.intel.com/ Reported-by: kernel test robot <oliver.sang@intel.com> Tested-by: Carel Si <beibei.si@intel.com> Cc: Jann Horn <jannh@google.com> Cc: Miklos Szeredi <mszeredi@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2021-12-13net: phy: add a note about refcountingRussell King (Oracle)
Recently, a patch has been submitted to "fix" the refcounting for a DT node in of_mdiobus_link_mdiodev(). This is not a leaked refcount. The refcount is passed to the new device. Sadly, coccicheck identifies this location as a leaked refcount, which means we're likely to keep getting patches to "fix" this. However, fixing this will cause breakage. Add a comment to state that the lack of of_node_put() here is intentional. Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-12-13selftest/net/forwarding: declare NETIFS p9 p10Hangbin Liu
The recent GRE selftests defined NUM_NETIFS=10. If the users copy forwarding.config.sample to forwarding.config directly, they will get error "Command line is not complete" when run the GRE tests, because create_netif_veth() failed with no interface name defined. Fix it by extending the NETIFS with p9 and p10.

2021-12-13net: dsa: mv88e6xxx: Unforce speed & duplex in mac_link_down()Marek Behún
Commit 64d47d50be7a ("net: dsa: mv88e6xxx: configure interface settings in mac_config") removed forcing of speed and duplex from mv88e6xxx_mac_config(), where the link is forced down, and left it only in mv88e6xxx_mac_link_up(), by which time link is unforced. It seems that (at least on 88E6190) when changing cmode to 2500base-x, if the link is not forced down, but the speed or duplex are still forced, the forcing of new settings for speed & duplex doesn't take in mv88e6xxx_mac_link_up(). Fix this by unforcing speed & duplex in mv88e6xxx_mac_link_down().

Without the bound checks for scpi_pd->name, it could result in the buffer overflow when copying the SCPI device name from the corresponding device tree node as the name string is set at maximum size of 30.

2021-12-12recordmcount.pl: look for jgnop instruction as well as bcrl on s390Jerome Marchand
On s390, recordmcount.pl is looking for "bcrl 0,<xxx>" instructions in the objdump -d outpout. However since binutils 2.37, objdump -d display "jgnop <xxx>" for the same instruction. Update the mcount_regex so that it accepts both.

2021-12-12s390/entry: fix duplicate tracking of irq nesting levelSven Schnelle
In the current code, when exiting from idle, rcu_irq_enter() is called twice during irq entry: irq_entry_enter()-> rcu_irq_enter() irq_enter() -> rcu_irq_enter() This may lead to wrong results from rcu_is_cpu_rrupt_from_idle() because of a wrong dynticks nmi nesting count. Fix this by only calling irq_enter_rcu().

2021-12-12selftests: Fix IPv6 address bind testsDavid Ahern
IPv6 allows binding a socket to a device then binding to an address not on the device (__inet6_bind -> ipv6_chk_addr with strict flag not set). Update the bind tests to reflect legacy behavior.

2021-12-12selftests: Fix raw socket bind tests with VRFDavid Ahern
Commit referenced below added negative socket bind tests for VRF. The socket binds should fail since the address to bind to is in a VRF yet the socket is not bound to the VRF or a device within it. Update the expected return code to check for 1 (bind failure) so the test passes when the bind fails as expected. Add a 'show_hint' comment to explain why the bind is expected to fail.
