2021-09-23mac80211-hwsim: fix late beacon hrtimer handlingJohannes Berg
Thomas explained in https://lore.kernel.org/r/87mtoeb4hb.ffs@tglx that our handling of the hrtimer here is wrong: If the timer fires late (e.g. due to vCPU scheduling, as reported by Dmitry/syzbot) then it tries to actually rearm the timer at the next deadline, which might be in the past already: 1 2 3 N N+1 | | | ... | | ^ intended to fire here (1) ^ next deadline here (2) ^ actually fired here The next time it fires, it's later, but will still try to schedule for the next deadline (now 3), etc. until it catches up with N, but that might take a long time, causing stalls etc. Now, all of this is simulation, so we just have to fix it, but note that the behaviour is wrong even per spec, since there's no value then in sending all those beacons unaligned - they should be aligned to the TBTT (1, 2, 3, ... in the picture), and if we're a bit (or a lot) late, then just resume at that point. Therefore, change the code to use hrtimer_forward_now() which will ensure that the next firing of the timer would be at N+1 (in the picture), i.e. the next interval point after the current time.

2021-05-31mac80211_hwsim: drop pending frames on stopJohannes Berg
Syzbot reports that we may be able to get into a situation where mac80211 has pending ACK frames on shutdown with hwsim. It appears that the reason for this is that syzbot uses the wmediumd hooks to intercept/injection frames, and may shut down hwsim, removing the radio(s), while frames are pending in the air simulation. Clean out the pending queue when the interface is stopped, after this the frames can't be reported back to mac80211 properly anyway.

2020-04-24mac80211_hwsim: notify wmediumd of used MAC addressesJohannes Berg
Currently, wmediumd requires each used MAC address to be configured as a station in the virtual air, but that doesn't make sense as any station could have multiple MAC addresses, and even have randomized ones in scanning, etc. Add some code here to tell wmediumd of used MAC addresses, binding them to the hardware address. Combined with a wmediumd patch that makes it track the addresses this allows configuring just the radio address (42:00:00:00:nn:00 unless the radio was manually created) in wmediumd as a station, and all addresses that the station uses are added/removed dynamically. Tested with random scan, which without this and the corresponding wmediumd change doesn't get anything through as the sender doesn't exist as far as wmediumd is concerned (it's random).

2019-10-04mac80211_hwsim: fix incorrect dev_alloc_name failure gotoMichael Vassernis
If dev_alloc_name fails, hwsim_mon's memory allocated in alloc_netdev needs to be freed. Change goto command in dev_alloc_name failure to out_free_mon in order to perform free_netdev.

2019-10-04mac80211: simplify TX aggregation startJohannes Berg
There really is no need to make drivers call the ieee80211_start_tx_ba_cb_irqsafe() function and then schedule the worker if all we want is to set a bit. Add a new return value (that was previously considered invalid) to indicate that the driver is immediately ready for the session, and make drivers use it. The only drivers that remain different are the Intel ones as they need to negotiate more with the firmware.

2019-10-01netfilter: drop bridge nf reset from nf_resetFlorian Westphal
commit 174e23810cd31 ("sk_buff: drop all skb extensions on free and skb scrubbing") made napi recycle always drop skb extensions. The additional skb_ext_del() that is performed via nf_reset on napi skb recycle is not needed anymore. Most nf_reset() calls in the stack are there so queued skb won't block 'rmmod nf_conntrack' indefinitely. This removes the skb_ext_del from nf_reset, and renames it to a more fitting nf_reset_ct(). In a few selected places, add a call to skb_ext_reset to make sure that no active extensions remain. I am submitting this for "net", because we're still early in the release cycle. The patch applies to net-next too, but I think the rename causes needless divergence between those trees.

2019-09-11mac80211_hwsim: Register support for HE meshpointSven Eckelmann
Some features of 802.11ax without central organizing (AP) STA can also be used in mesh mode. hwsim can be used to assist initial development of these features without having access to HW.

2019-07-29mac80211_hwsim: Fix possible null-pointer dereferences in hwsim_dump_radio_nl()Jia-Ju Bai
In hwsim_dump_radio_nl(), when genlmsg_put() on line 3617 fails, hdr is assigned to NULL. Then hdr is used on lines 3622 and 3623: genl_dump_check_consistent(cb, hdr); genlmsg_end(skb, hdr); Thus, possible null-pointer dereferences may occur. To fix these bugs, hdr is used here when it is not NULL. This bug is found by a static analysis tool STCheck written by us.

2019-07-26mac80211_hwsim: Extended Key ID API updateAlexander Wetzel
Prepare hwsim Extended Key ID support for a mac80211 API change. The mac80211 flag IEEE80211_HW_EXT_KEY_ID_NATIVE is being replaced by NL80211_EXT_FEATURE_EXT_KEY_ID which only must be set by drivers when they support HW crypto. This reverts commit cfe7007a9b4c ("mac80211_hwsim: Extended Key ID support").
