2021-10-22One could end up with the wrong encoding in xenocara while having a uccAnton Lindqvist
keyboard attached and /etc/kbdtype being present. The advertised encoding of a wsmux is a bit fragile as the last attached device will dictate it. If this happens to be a ucc keyboard, KB_US will always be the advertised encoding as its encoding is immutable and /etc/kbdtype is ignored. Instead, do not advertise the encoding for ucc devices when the parent mux queries its attached devices. However, asking the device directly (i.e. bypassing the mux) still returns the encoding as wsconsctl(8) would otherwise report an error. Thanks to landry@ for the report and testing.

access garbage collector data. This is the next step to make UNIX domain sockets locking fine grained. This also moves M_WAIT/M_WAITOK allocations out from `unp_lock' rwlock(9). The lock order between fdplock() and `unp_lock' changed and now fdplock() should be taken first. This was not required, but helps to mpi@'s knote(9) related work. ok bluhm@

2021-10-21Remove hifn(4), safe(4), and ubsec(4) crypto drivers. They requireAlexander Bluhm
the asynchronous crypto API which makes progress in MP difficult. The hardware is rarely available. They support only obsolete crypto algorithms. Scheduling crypto tasks via PCI is probably slower than the CPU, especailly as modern CPUs have their own accelerators.
2021-10-21Have ampintcmsi(4) go through the list of interrupt controllers to find thePatrick Wildt
correct parent. So far we were directly calling some ampintc(4) code, which is fine for regular hardware. With Parallels on the Apple M1, ampintcmsi(4) is combined with agintc(4), which is quite a surprise. Luckily both types of interrupt controllers use the same API for passing interrupt information, so we can craft one structure and both ampintc(4) and agintc(4) will happily work with it. ok kettenis@
2021-10-21Move vfs_stall_barrier() from the fd layer into vn_lock() and the vfs layer.Claudio Jeker
vfs stalling is used by suspend/resume and by vmt(4) to stall any filesystem operation from altering the state on disk. All these operations will call vn_lock and be stalled. Adjust vfs_stall_barrier() to allow the lock owner to still progress so that suspend can sync the filesystems after stalling vfs operation. OK mpi@

2021-10-19vnode: remove VLOCKSWORK and check locking when vop_islocked != nullopSebastien Marie
This flag is currently used to mark or unmark a vnode to actively check vnode locking semantic (when compiled with VFSLCKDEBUG). Currently, VLOCKSWORK flag isn't properly set for several FS implementation which have full locking support. This commit enable proper checking for them too (cd9660, udf, fuse, msdosfs, tmpfs). Instead of using a particular flag, it directly check if v_op->vop_islocked is nullop or not to activate or not the vnode locking checks. ok mpi@

2021-10-14Release solock() before call unp_externalize().Vitaliy Makkoveev
A little step forward to make UNIX domain sockets locking fine grained. The closest goal is to introduce the new rwlock(9) and use it to protect garbage collector data. This leaves existing `unp_lock' rwlock(9) which cowers the whole layer for per-socket data only and allows to replace it with per-socket `so_lock' with further diffs. Except file descriptor table unp_externalize() operates with the garbage collector data only such as `unp_rights', `unp_msgcount' directly and `unp_deferred' through unp_discard(). I want to introduce the new garbage collector rwlock(9) with the separate diff, so `unp_lock' is still taken within unp_externalize() around garbage collector data access. But right now M_WAITOK allocation removed from rwlock(9). Also useless M_WAITOK allocation and fdplock()/fdpunlock() dances removed from the error path. The `unp_lock' and fdplock() are not taken together within unp_externalize() but unp_internalize() still enforces `unp_lock' -> fdplock() lock order. This rests the only place and will be changed with the upcoming unp_internalize() and garbage collector rwlock(9) diffs. ok bluhm@

2021-10-14Implement select(2) and pselect(2) on top of kqueue.Martin Pieuchot
The given set of fds are converted to equivalent kevents using EV_SET(2) and passed to the scanning internals of kevent(2): kqueue_scan(). Those events are lazily deleted to reduce the overhard of freeing/allocating them when select(2) is called in a loop. ktrace(1) will now output the converted kevents on top of the usuals set bits to be able to find possible error in the convertion. This switch implies that select(2) and pselect(2) will now query the underlying kqfilters instead of the *_poll() routines. An increase in latency is visible, especially with UDP sockets and NET_LOCK()-contended subsystems and will be addressed in a next step. The various *_poll() routines could be removed as soon as poll(2) and ppoll(2) are also converted. Based on similar work done on DragonFlyBSD with inputs from from visa@, millert@, anton@, cheloha@, thanks! ok claudio@, bluhm@
2021-10-13Remove redundant NULL checks in IPsec which are never reached.Alexander Bluhm
ok mvs@
2021-10-13The function crypto_dispatch() never returns an error. Make itAlexander Bluhm
void and remove error handling in the callers. OK patrick@ mvs@
2021-10-13The function ipip_output() was registered as .xf_output() xformAlexander Bluhm
function. But was is never called via this pointer. It would have immediatley crashed as mp is always NULL when called via .xf_output(). Do not set .xf_output to ipip_output. This allows to pass only the parameters which are actually needed and the control flow is clearer. OK mpi@
2021-10-13The kernel crypto framework sometimes returned an error, sometimesAlexander Bluhm
the callback was called, and sometimes both. So the caller of that API could not release resources correctly. A bunch of errors can or should not happen, replace them with an assert. Remove redundant checks. crypto_invoke() should not return the error, but pass it via callback. Some old hardware drivers keep part of their inconsistency as I cannot test them. OK mpi@

2021-10-12Make our old BSSID available to iwx_newstate_task() when roaming.Stefan Sperling
ic_bss->ni_bssid has already been overwritten once we enter iwx_newstate_task() to perform the state transitions necessary for roaming to our new access point (RUN->AUTH->ASSOC->RUN). We do however use the BSSID in commands sent to firmware. Cache our BSSID in struct iwx_node such that firmware commands keep using the old BSSID while we are still tearing things down. Switch to the new BSSID only once we start back up in iwx_auth(). This should be consistent from the firmware's point of view. Same fix as committed for iwm(4) recently.
2021-10-12Explicitly stop iwx(4) Rx block ack when roaming between access points.Stefan Sperling
This is similar to a recent fix committed to iwm(4). Unlike iwm(4) we do not need to disable Tx aggregation queues in iwx(4). Attempting to do so would cause fatal firmware errors. Tested by jmc@ and myself.

2021-10-12Fix the deadlock between uvn_io() and uvn_flush() by restarting the fault.Martin Pieuchot
Do not allow a faulting thread to sleep on a contended vnode lock to prevent lock ordering issues with upcoming per-uobj lock. Also reduce the sleep value for VM_PAGER_AGAIN from 1sec to 5nsec to not add visible slowdown when starting a multi-threaded application with threads that fault on the same vnode (chromium, firefox, etc).

2021-10-11Add support for 802.11n 40MHz channels to the iwm(4) driver.Stefan Sperling
According to 11n MCS index tables our maximum data rate is now 300 Mbit/s at MCS 15, excluding protocol overhead. I have measured up to 200Mbit/s of effective throughput on clean 5GHz channels. The driver enables use of 40MHz channels automatically as long as the access point announces support for such channels in its beacons. In case 40MHz transmissions fail we ask firmware to retry with a 20MHz transmission. There is no integration with ifconfig yet, so use of 40MHz is not yet displayed there. In the meantime, tcpdump(8) can be used to check if the current access point supports 40MHz: tcpdump -n -i iwm0 -v -y IEEE802_11_RADIO -s 4096 type mgt and subtype beacon Channel width is displayed in the HT operation information element, where a 40MHz channels looks like this: htop=<40MHz chan X:Y ...> Tested: 7260: florian, bcallah 7265: landry 8260: bket 8265: stsp, abieber, Matthias Schmidt, Josh Rickmar, empee on mastodon 9560: stsp

and notify drivers when the channel width has changed.
2021-10-11Add support for 40MHz channels to net80211 RA.Stefan Sperling
For the moment we use either the 40MHz rate set or the 20 MHz one, depending on whether our peer supports 40MHz channels. If this turns out to be suboptimal we could probe the 40MHz and 20MHz rate sets separately to detect which one works better. The same applies to use of the short guard interval (SGI), which is either always on or off at the moment. Again, probing for this could be added later if needed.

2021-10-10Apparently it is possible for firmware to indicate that SMCCC_VERSION isMark Kettenis
implemented but have that call return NOT_SUPPORTED. Makes no sense, but the SMCCC standard documents this and tells us to treat this as v1.0. Change the code accordingly. Turn a few checks that should always be true into KASSERTs to keep the control flow simple. ok patrick@
