2020-07-05uvideo_querycap(): Set the 'device_caps' field of struct v4l2_capability ↵Landry Breuil
like done in utvfu(4) Fixes webcam detection in firefox 78, where code was added to check for V4L2_CAP_VIDEO_CAPTURE capability on 'device_caps', whereas we only set it in the 'capabilities' field. According to https://www.kernel.org/doc/html/v4.14/media/uapi/v4l/vidioc-querycap.html#description those distinct fields are here for drivers that provide several devices, but firefox decided to check for 'device_caps' field instead of 'capability' (cf https://hg.mozilla.org/integration/autoland/rev/33facf191f23) - so fill the field for compatibility reasons, while https://bugzilla.mozilla.org/show_bug.cgi?id=1650572 discusses with upstream what's the right way. ok mglocker@

completely fix the case where the FPU is used in a signal handler but it is part of the solution and makes sure the processor mode check in sys_sigreturn() passes if the process was using the FPU when the signal happened.

2020-07-04Avoid malloc(3) calls in signal handlerkn
Fetch aborts through SIGINT (^C) print a message with fputs(3), but this calls malloc() on its own, which is not supported from interrupt handler context. Fix it by using write(2) which avoids further memory allocations. While here, merge abortfile() into the identical aborthttp() with a more generic "fetch aborted." message for simplicity. Spotted with vm.malloc_conf=SU and ^C on a port's "make fetch" causing ftp(49660) in malloc(): recursive call Abort trap (core dumped) OK jca (who came up with using write(2) independently)

Simplify the logic by always exporting the return value and errno in the syscall profiler.

2020-07-04Add a missing circular_init() call in the TLS ordering test.Joel Sing
This makes the regress work correctly again - this was previously masked by the fact that tls_close() (and hence SSL_shutdown()) was draining the circular buffer, whereas now we're leaving data behind from a previous test, resulting in the ordering test failing.

2020-07-04Use klist_invalidate() in knote_processexit()Visa Hankala
This leaves knote_remove() for kqueue's internal use. As a result, knote_remove() is used to drop knotes from the knlist of a single kqueue instance. klist_invalidate() clears knotes from a klist that can contain entries from different kqueue instances. Use FILTEROP_ISFD to control how klist_invalidate() treats knotes, to preserve the current behaviour of knote_processexit(). All the existing callers of klist_invalidate() are fd-based. The existing code rewires and activates knotes to give userspace a clear indication that the state of the fd has changed. In knote_processexit(), any remaining knotes in ps_klist are non-fd-based (EVFILT_SIGNAL). Those are dropped without notifying userspace. OK mpi@
2020-07-04It's been agreed upon that global locks should be expressed usinganton
capital letters in locking annotations. Therefore harmonize the existing annotations. Also, if multiple locks are required they should be delimited using commas. ok mpi@
2020-07-04Permit the stack to check transport and network checksums. Although the linkRichard Procter
provides stronger integrity checks, it needn't cover the end-to-end transport path. And it is in any case a layer violation for one layer to disable the checks of another. Skipping the network check saved ~2.4% +/- ~0.2% of cp_time (sys+intr) on the forwarding path of a 1Ghz AMD G-T40N (apu1). Other checksum speedups exist which do not skip the check. ok claudio@ kn@ stsp@

2020-07-03Use an LFENCE instruction everywhere where we use RDTSC when we areMark Kettenis
doing some sort of time measurement. This is necessary since RDTSC is not a serializing instruction. We can use LFENCE as the serializing instruction instead of CPUID since all amd64 machines have SSE. This considerably reduces the jitter in TSC skew measurements. ok deraadt@, cheloha@, phessler@
2020-07-03Rename IN6_IFF_PRIVACY to IN6_IFF_TEMPORARY.Florian Obser
This is the name the other BSDs use for this, there is no reason to be different, the IPv6 RFCs call these addresses temporary, and some software in ports wants to use this as well. Most recently pointed out for firefox by landry. OK claudio, sthen
