2020-09-03The "USL" VT switch and keyboard ioctls are a hack and don't follow theMark Kettenis
proper BSD way where the third argument is always a pointer and data is transferred between userland and kernel using copyin(9) and copyout(9). Intead an int is encoded in the thirs argument. This works on 32-bit architectures and little-endian 64-bit architectures. But not on big-endian 64-bit architectures. Deal with this by handling the argument as long (which matches the size of a pointer). Hopefully we can eliminate these ioctls in the near future. ok deraadt@

2020-09-02Don't rely on wTotalLength for usbd_get_cdesc() malloc/free but on theMarcus Glocker
actual length which has been allocated. We saw cases where the wTotalLength value is changing on a second read, e.g. when a USB device was waked up from sleep mode. ok mpi@

2020-08-30avoid a invalid pointer deref in hvn_stop()Jonathan Gray
intr_barrier() now uses the argument so directly call sched_barrier(NULL) which is what intr_barrier() used to do until recently. problem reported by and fix tested by Andre Stoebe
2020-08-30PLL1(CPU_PLL) stability improvement for Allwinner H3/H2+SASANO Takayoshi
Due to unstable of PLL1, sometimes the system has hanged up especially at boot. This is observed at Allwinner H3/H2+ processor. To solve the problem, PLL1 setting procedure is same as Linux. 1. change clock source to 24MHz 2. wait 1usec (new) 3. disable PLL1 (new) 4. set new NKMP value, but M should be 1 5. re-enable PLL1 (new) 6. wait PLL1 stable (modified) 7. change clock source to PLL1 8. wait 1usec (new) Once disable PLL1 before setting NKMP is very important. And, sometimes LOCK flag is set even if PLL has not locked yet so wait for PLL is modified with simple delay() by the value of PLL_STABLE_TIME_REG1 register. Not only Allwinner H3/H2+ but also all (i.e. A64) Allwinner processors datasheet has "If the clock source is changed, at most to wait for 8 present running clock cycles." sentence at CPU clock source selection field of CPU/AXI configuration register. But this is ambiguous that _who_ should do _what_ during that cycles. It is unclear that changing clock source itself invoke PLL1 unstability. For safety, added 1usec wait after changing clock source like Linux. ok by kettenis@, thanks to adr at sdf dot org
2020-08-29Before clearing the kcov descriptor associated with a thread make sureanton
no other thread is currently within a remote section. Otherwise, the remote subsystem could end up in a broken state where it doesn't reset the necessary bits upon leaving the remote section. Therefore introduce the kr_barrier() routine which waits until all ongoing remote sections have been left. Also, extend the scope of the mutex to also cover fields of struct kcov_dev. This is necessary to ensure correctness. Reported-by: syzbot+64122a5f01be1b1abb96@syzkaller.appspotmail.com

2020-08-27Fix a potential panic during free(9) which can be caused by an USBMarcus Glocker
device which returns a spurious value for wTotalLength on a configuration descriptor request. Therefore don't relay on wTotalLength for free(9) but on the length variable which was used for the malloc(9) before. The issue was reported by Mikolaj Kucharski <mikolaj (at) kucharski (dot) name> on bugs@. Discussed and ok deraadt@

2020-08-27Clear endpoint stall on open(2) of /dev/uhidX to synchronize toggle bitPatrick Wildt
as needed on xhci(4) machines. On non-xhci(4) we save and restore the toggle bit on close/open of a pipe. With xhci(4) this does not seem to be possible, at least I haven't yet found it. This means that on those machines with xhci(4), after a pipe close/open, the device will use the previous state, while xhci(4)'s state is reset to default. By issuing a clear endpoint stall we reset the device's toggle bit. Now every time a /dev/uhid is (re-)opened the state should be synchronized.

2020-08-27Reorder the acpi attach process so we look at Processor() CPU nodesJonathan Matthew
after Device() ones, since we should prefer the newer node type. If we see any Device() nodes, don't attach acpicpu(4) to any Processor() nodes if they're also present. This also makes acpitz(4) and acpipwrres(4) devices attach slightly later. ok kettenis@, also tested by jmc@

2020-08-23uhidev(4) does apply the SET_IDLE request to all its child driversMarcus Glocker
today. This doesn't seem to be right, since SET_IDLE limits the reporting frequency for interrupt IN endpoints, normally only required on keyboard and mouse-like input devices. We noticed recently that other device types, like e.g. the Cyrus soundKey uaudio(4), will stall after the SET_IDLE request has been issued. Therefore we move the SET_IDLE request only to the uhidev(4) child drivers which seem to require this request. Those we have identified to be; ukbd(4), ums(4), umstc(4), umt(4), utpms(4), and uwacom(4). Suggested and ok mpi@
