files src/sys/dev/usb/uaudio.c log diff annotate
message Fix uaudio(4) detection on Logitech Webcam C200/C210/C250/C270/C310/C500.

Those devices have a broken AudioControl descriptor which advertises a
bad value for bLength for the FEATURE_UNIT sub-descriptor, so add a
quirk 'fixing' this bLength so that uaudio(4) attaches properly instead
of bailing out with 'audio descriptors make no sense, error=4'.

My C310 now properly attaches but doesnt seem to work right now, this is
a different issue that will be worked on.

Thanks to tb@, remi@, weerd@, Raf Czlonka, Base Pr1me, Jordan Geoghegan,
Peter J. Philipp, Alfredo Vogel, James Hastings, Bruno Flueckiger,
Remco & Alex Tsang for providing lsusb -v output for a large variety of
Logitech Webcams.

files src/sys/kern/kern_sched.c log diff annotate
message Release the kernel lock fully on thread exit. This prevents a locking
error that would happen otherwise when a traced and stopped
multithreaded process is forced to exit. The error shows up as a kernel
panic when WITNESS is enabled. Without WITNESS, the error causes
a system hang.

sched_exit() has expected that a single KERNEL_UNLOCK() would release
the lock completely. That assumption is wrong when an exit happens
through the signal tracing logic:

issignal <-- KERNEL_LOCK()
userret <-- KERNEL_LOCK()

The error is a regression of r1.216 of kern_sig.c.

message Fix a locking error in spec_setattr(). Unlike many VOP operations,
VOP_SETATTR() does not release the vnode lock (and it has never done
the unlocking in the past). Therefore spec_setattr() has to keep the
argument vnode locked and unlock v_specparent instead after the nested

files src/sys/kern/kern_descrip.c log diff annotate
message Fix an argument type error that happens when translating fcntl(F_SETOWN)
to ioctl(TIOCSPGRP). The ioctl handlers expect a pointer to an int, so
read the argument into a local int variable and pass the variable's
address to the handler instead of referencing SCARG(uap, arg) directly.
