passive scans, which works well enough as long as you don't use hidden networks. Even without hidden networks, using an active scan seems to be quicker and feels like it works better. ok stsp@

2019-10-28Better error handling for bwfm(4) connection attempts. When we failPatrick Wildt
to connect, e.g. due to a timeout, we will switch the state to SCAN. Unfortunately this skips clearing the active channel set, which means that on a scan on all bands only the nodes on the active channel set, which is defined by whatever node we tried to connect to, are allowed and all other APs are ignored. Fix this by properly calling begin_scan(). When we fail to connect and start a scan, make sure to let the chip know that we don't want to associate anymore. Another issue existed when we interrupt a scan, for instance by setting a new nwid or wpakey. In this case we didn't abort the scan and started a new scan while the old one as still active. This could lead to a SCAN -> SCAN transition loop. Remove the "set ssid" event, since this would be an event in addition to a failed auth/assoc event, which would make us try to handle failure twice.

similarities between the two and using a common approach helps fixing bugs. The new driver is better integrated with the device tree framework and is faster (mainly because the DMA engine is configured properly now). Tested on all currently supported variants of the hardware. ok jsg@, jmatthew@

2019-09-12Make wireless drivers call if_input() only once per interrupt.Stefan Sperling
This reduces drops caused by the ifq pressure drop mechanism and hence increases throughput. Such drops are visible with e.g. 'netstat -dnI iwm0'. Not all affected drivers have been tested yet but these changes are largely mechanical and should be safe. As usual, please report any regressions.

2019-09-01Adopt the SCSI versioning #define's from FreeBSD. Eliminate theKenneth R Westerback
now unneeded version_to_spc() mapping array, a duplicate #define and a couple of magic numbers. Toss in some comments for future generations of spelunkers. Makes it possible to check for specific SPC versions when new features or eliminated features require such a check. No intentional functional change.
2019-08-27Keep ieee80211_node structures cached across scans, rather thanStefan Sperling
wiping the entire cache every time a scan is triggered. This has benefits for userland programs trying to look at scan results, and for drivers which don't get a full view from hardware on every scan. Nodes will still be evicted from the cache in one of several ways: Add a new way of timing out inactive nodes which don't send a beacon within 10 scan iterations, for client mode only. This should get rid of stale APs if we're scanning for some time in a changing environment. If we fail to associate a few times, the corresponding node is removed. If net80211 transitions back to INIT state (e.g. because of a user-initiated configuration change) all nodes are removed. When a background scan starts all nodes will be removed. This could be revisited later but has been intentionally left as-is for now. Tested by myself, jmc@, benno@, procter@ on iwm(4), athn(4) and ral(4).

2019-07-27Make target numbers match the NVMe namespace identifiers. This fixes bootingMark Kettenis
from nvme(4) on sparc64 as the OBP device paths contain namespace identifiers that we end up matching to targets when trying to find the device we booted from. Also results in (slightly) cleaner code and less confusion as the numbers now match instead of being off-by-one. ok dlg@

2019-06-25Turn off the code which waits for AHCI_PREG_CMD_CR to be set by thePatrick Wildt
HBA after ahci_default_port_start() sets AHCI_PREG_CMD_ST. The AHCI spec. rev. 1.3 only requires the inverse to be true, i. e. that a HBA clears AHCI_PREG_CMD_CR when AHCI_PREG_CMD_ST gets cleared by software/driver. In fact, some HBAs will not raise AHCI_PREG_CMD_CR as an immediate consequence of AHCI_PREG_CMD_ST being set. Actually neither the FreeBSD, Linux nor NetBSD counterpart of ahci(4) has an analogous check. Disabling that wait fixes "failed to start command DMA on port N, disabling" bails during attach. From Marius Strobl ok deraadt@ jmatthew@
2019-06-03Prevent corruption of the pckbc command queue. If multiple synchronousanton
commands are in flight and all corresponding threads are sleeping waiting for a response, the first command to timeout will clear the command queue. The remaining threads once awake will then try to remove a dequeued command from the queue, leading to corruption. Instead, remove commands from the queue before waking up the sleeping thread. A quirk is still needed to handle the case where tsleep() returns successfully during suspend. ok mpi@ visa@ Reported-by: syzbot+fe74fc50c630bfa26302@syzkaller.appspotmail.com

2019-05-12Fix 'ifconfig nwflags; These flags ended up overlapping with other flagsStefan Sperling
in ieee80211com's ic_flags because we haven't been paying attention to them (they're not in the same place in the code and hence easy to miss). Move them to a dedicated variable to avoid this problem in the future. Add a new 'stayauth' nwflag which can be set to let net80211 ignore deauth frames. This can be useful when deauth frames are being persistently spoofed by an attacker. Idea from beck@ ok beck@ phessler@
2019-05-10Explicitly disable BCM4331 chips present in 2011-2012 Apple Mac systems.Brent Cook
The Mac EFI firmware enables the wireless controller, but does not disable it, so it continues to receive packets and signal interrupts. This was originally seen as an interrupt storm that consumes about 50% of CPU0 on affected machines. The issue was originally discovered in 2012 by Matthew Garret with a partial fix in Grub, then Lukas Wunner added a fix for the Linux kernel in 2016. This piggy-backs on the most-related driver (bwi) for the purpose of detection and mapping the control registers, but does not actually register the driver if the affected chip is detected.

2019-04-29MC146818_GETTOD: Check for RTC rollover during read.cheloha
Because the RTC is still ticking it is theoretically possible for the second to roll over while we are reading the clock. This is basically impossible on real/practical hardware but is an interesting corner case for e.g. a VM reading an emulated MC146818 during an exit to userspace. This doesn't check *every* register, so if it takes you a multiple of 60 seconds to read the RTC this change won't help you. But you've got bigger problems at that point.
