2022-02-16rev 1.4 was wrong to put potential IO operations after _GTS.Theo de Raadt
re-creating the original (2 weeks ago) order of last-minute-disk-parking needs a different approach, hmm.

failure modes. Also, pack the code a little bit, easier to read.

2022-02-16if the lids indicate we are not supposed to wakeup, return EAGAIN ratherTheo de Raadt
than scheduling an acpi thread
2022-02-16If the lid is closed, suspend_finish() now returns EAGAIN, so go to the topTheo de Raadt
and restart the suspend all over again. This was previously done by issuing a task to the acpi thread, but this is simpler. (I want to try to duplicate these tests earlier in the resume path...)
2022-02-16change MD gosleep() and sleep_finish() to return int, the MI code will beTheo de Raadt
able to react to this suitably.
2022-02-16Currently, wskbd_set_mixervolume() only adjusts the volume of the firstAnton Lindqvist
attached audio device, i.e. audio0. This approach does not work well while using additional audio devices equipped with physical volume keys since those would only affect the volume of audio0. Instead, correlate audio and ucc devices attached over USB in order to adjust the volume of the correct audio device. This is done by passing a cookie from the common point of attachment which is later used to correlate the audio and wskbd device. The same approach could be adopted for audio and wskbd devices attaching on a different bus. Keep in mind that it's of importance to make use of and increment the same global cookie identifier to avoid collisions. Makes the volume keys on my Logitech G435 Headset do the right thing. ok ratchov@

2022-02-16check pf rule "set prio" values consistently.David Gwynne
consistently means we do the check in pf_rule_copyin() so both DIOCADDRULE and DIOCCHANGERULE have the prio values checked. this in turn prevents invalid prio values getting set on a rule via DIOCCHANGERULE. this was caught by a kassert in the ifq priq code firing.

2022-02-16prevent (re)opening of tun/tap interfaces that are being destroyed.David Gwynne
if an open tun (or tap) device is destroyed via the clone destroy ioctl (eg, like what ifconfig destroy does), there is a window while the open device is being revoked on the vfs side that a third thread can come and open it again. this in turn triggers a kassert in the ifconfig destroy path where it expects the device to be closed. fix this by having tun_dev_open check for the TUN_DEAD flag that the destroy function sets. this still relies on the kernel lock for serialisation.

2022-02-16fill in support for rx prio handling.David Gwynne
2022-02-16rewrite vxlan to better fit the current kernel infrastructure.David Gwynne
the big change is removing the integration with and reliance on bridge(4) for learning vxlan endpoints. we have the etherbridge layer now (which is used by veb, nvgre, bpe, etc) so vxlan can operate independently of bridge(4) (or any other driver) while still dynamically learning about other endpoints. vxlan now uses the udp socket upcall mechanism to receive packets. this means it actually creates and binds udp sockets to use rather adding code in the udp layer for stealing packets from the udp layer. i think it's also important to note that this adds loop prevention to the code. this stops a vxlan interface being used to transmit a packet that was encapsulated in itself. i want to clear this out of my tree where it's been sitting for nearly a year. noone seems too concerned with the change either way. ok claudio@

The (known) lock order reversals which now occur more reliably and much earlier on WITNESS boots with this diff knock out syzcaller reports since syzcaller stops at the first "crash report": https://syzkaller.appspot.com/bug?id=81b39e970cd2eb21b97d1b31746c693e300fd2dd

2022-02-15only tweak ifp if_flags while holding NET_LOCK.David Gwynne
tun_dev_open and tun_dev_close were being optmistic.
2022-02-15make tun_link_state take the ifnet pointer instead of tun_softc.David Gwynne
it only works on struct ifnet data, so passing ifp makes it clearer what's actually being manipulated. also fix tun_dev_open so tun_link_state is called before if_put instead of immediately after.

2022-02-14Unwire with map lock heldKlemens Nanni
This is an updated version of uvm_map.c r1.283 "Unwire with map lock held". The previous version introduced a use-after-free by not unlocking vm_map locks in uvm_map_teardown(), resulting in dangling references on the reaper's lock list (thanks visa!). Lock and unlock the map in around uvm_map_teardown() instead. This code path holds the last reference, hence the lock isn't strictly needed except for satisfying upcoming locking assertions. Tested on amd64, arm64, i386, macppc, octeon, sparc64. This time also with WITNESS enabled (except on sparc64 which builds but does not boot with WITNESS; this is a known issue). OK mpi visa
