2019-11-06Make iwn(4) flush remaining frames on the Tx aggregation queue whenStefan Sperling
Tx aggregation is stopped. Fixes a bug where outstanding frames on the aggregation queue interfere with roaming to another AP. net80211 will only roam once all outstanding frames destined for the old AP have been sent, i.e. once that AP node's Tx refcount goes to 0. Any outstanding frames sitting in the Tx aggregation queue, waiting to be ACKed, will keep this refcount above zero. To make roaming work reliably in combination with Tx aggregation, the driver must ensure that ieee80211_release_node() gets called for each frame on the queue when Tx aggregation is stopped.

2019-11-06Fix RTA_DNS checks:Florian Obser
Do not overwrite the address family, we need to know if this is IPv4 or IPv6 to parse the message. Nameservers are IP addresses, not NUL-terminated strings. Check that the length is a multiple of the length of an IP address. OK krw
2019-11-06Raise net80211's "beacon miss" threshold to avoid frequent re-connectsStefan Sperling
to APs that are relatively far away and suffer some packet loss. The former threshold was 7 beacons (about 700 ms). This raises the threshold to 30 beacons (about 3 seconds). Should still be good enough for detecting APs that have disappeared, and makes wifi networks provided by the University of Bucharest more reliable in the p2k19 hackroom. While here, make 'ifconfig iwm0/iwn0 debug' print an obvious message when we believe that the AP has disappeared. Problem reported and fix tested by landry@ / pirofti@ ok mpi@ sthen@

2019-11-06replace the hooks used with if_detachhooks with a task list.David Gwynne
the main semantic change is that things registering detach hooks have to allocate and set a task structure that then gets added to the list. this means if the task is allocated up front (eg, as part of carps softc or bridges port structure), it avoids the possibility that adding a hook can fail. a lot of drivers weren't checking for failure, and unwinding state in the event of failure in other parts was error prone. while doing this i discovered that the list operations have to be in a particular order, but drivers weren't doing that consistently either. this diff wraps the list ops up so you have to seriously go out of your way to screw them up. ive also sprinkled some NET_ASSERT_LOCKED around the list operations so we can make sure there's no potential for the list to be corrupted, especially while it's being run. hrvoje popovski has tested this a bit, and some issues he discovered have been fixed. ok sashan@

2019-11-04remove mobileip(4)David Gwynne
noone seems to use it, and we should not encourage people to use it by having it available. it's been disabled for most of the last release and noones asked for it in 6.6, so i'm taking that as an ok for this removal.
2019-11-04Restore the old way of dispatching dead procs through idle proc.Visa Hankala
The new way needs more thought.

2019-11-04Add ogx(4), a driver for the OCTEON III network processor.Visa Hankala
This network driver covers higher-end models of the OCTEON III family. They have a modified design whose interface is not compatible with the lower-end models or earlier chip generations. The code is still a work in progress. However, it is capable enough to make the SGMII port functional on the CN7360. No objection from deraadt@
2019-11-04Switch iwm 3160, 7260, and 7265 to -17 firmware images.Stefan Sperling
7260 tested by florian 7265 tested by kettenis 3160 should work as it's a trimmed-down variant of 7260 Please report any problems as soon as possible.
2019-11-04Make iwm send the DQA command later, as Linux does. We were sending it toStefan Sperling
the init firmware which does not need it. The main runtime firmware needs it. This actually enables DQA mode, and two further problems showed up: 1) Correctly configure the AUX station queue in the DQA case. 2) Always transmit our own frames via the AP's station. The AUX station is meant to be used for firmware-generated frames only. Tested on 7260, 7265, and 8265 with standard -current firmware images. Required for newer firmware versions. ok patrick@

2019-11-02softclock: move softintr registration/scheduling into timeout modulecheloha
softclock() is scheduled from hardclock(9) because long ago callouts were processed from hardclock(9) directly. The introduction of timeout(9) circa 2000 moved all callout processing into a dedicated module, but the softclock scheduling stayed behind in hardclock(9). We can move all the softclock() "stuff" into the timeout module to make kern_clock.c a bit cleaner. Neither initclocks() nor hardclock(9) need to "know" about softclock(). The initial softclock() softintr registration can be done from timeout_proc_init() and softclock() can be scheduled from timeout_hardclock_update(). ok visa@

2019-10-31In 2013, when OpenBSD/armv7 was still rather early, improvements forPatrick Wildt
that platform have been trickling in bit by bit. One of those changes unfortunately introduced a regression in cache flushes. The check for the length in the cache-flush-loop was changed from the instruction bpl to bhi. This has the effect that it does not branch on zero anymore. Due to the length decrement at the beginning of the function, which was not removed, a length of (n * cacheline) + 1 means that the loop misses one run! This means it is possible that the last byte of a DMA transfer was incorrect, as one could see on network packets often enough. Remove that instruction, which makes it even more similar to the OpenBSD/arm64 code. ok deraadt@
2019-10-31Make background scans less frequent if we keep choosing the same AP.Stefan Sperling
This helps a bit in situations where a single AP is used and background scans are causing packet loss, as seen with Jesper Wellin's Broadcom-based AP and my Android phone in hotspot mode. This is not a proper fix but our background scan frequency against a single AP was much higher than needed anyway. Tested by jan, job, benno, Tracey Emery, Jesper Wallin
