Basic signal tests: Can we deliver a signal?Basic signal tests that tests can we deliver a signal via raise() andcan we deliver one via SIGALARM asynchronously.In addition, tests whether or not on ARM T32 (Thumb) code can interruptA32 (normal) and vice versa.While this test is aimed at ensuring basic qemu signals are working,it's good to have in the base.Sponsored by: NetflixDiscussed with: kevans, cognetDifferential Revision: https://reviews.freebsd.org/D33078(cherry picked from commit afc5ab870d8661a7dacdbd65554c2f3533aecb8d) List of files: /freebsd-13.1/tests/sys/kern/Makefile

Fix build with read-only source dir after 83c20b8a2da0I changed the Makefile to use SRCS instead of LDADD, but since there isstill and absolute path to the source the .o file was created inside thesource directory instead of the build directory.It would be nice if this was an error/warning by default, but for now justfix this issue by using .PATH and the base name of the file.Reported by: cy, peterj(cherry picked from commit 8b820df156e065f48857dca89a89462074659e14) List of files: /freebsd-13.1/tests/sys/kern/Makefile

Whena new table is allocated, the old table is placed in a free list and held ontountil all processes referencing them exit.When a new file descriptor table is allocated, the old file descriptor tablecan be freed when the current process has a single-thread and the filedescriptor table is not being shared with any other processes.Reviewed by: kevansApproved by: kevans (mentor)Differential Revision: https://reviews.freebsd.org/D18617 List of files: /freebsd-13.1/tests/sys/kern/Makefile

This will simplify checks in downstreamconsumers targeting prototype instruction sets.The only place we check for MACHINE_ARCH == aarch64 is when building thedevice tree blobs.

Wed, 25 Sep 2019 18:03:18 +0000

Add linux-compatible memfd_creatememfd_create is effectively a SHM_ANON shm_open(2) mapping with optionalCLOEXEC and file sealing support. This is used by some mesa parts, somelinux libs, and qemu can also take advantage of it and uses the sealing toprevent resizing the region.This reimplements shm_open in terms of shm_open2(2) at the same time.shm_open(2) will be moved to COMPAT12 shortly.Reviewed by: markj, kibDifferential Revision: https://reviews.freebsd.org/D21393 List of files: /freebsd-13.1/tests/sys/kern/Makefile

b3c0d957 - Add support for the Clang Coverage Sanitizer in the kernel (KCOV).

Sat, 12 Jan 2019 11:21:28 +0000

Add support for the Clang Coverage Sanitizer in the kernel (KCOV).When building with KCOV enabled the compiler will insert function callsto probes allowing us to trace the execution of the kernel from userspace.These probes are on function entry (trace-pc) and on comparison operations(trace-cmp).Userspace can enable the use of these probes on a single kernel thread withan ioctl interface. It can allocate space for the probe with KIOSETBUFSIZE,then mmap the allocated buffer and enable tracing with KIOENABLE, with thetrace mode being passed in as the int argument. When complete KIODISABLEis used to disable tracing.The first item in the buffer is the number of trace event that havehappened. Userspace can write 0 to this to reset the tracing, and isexpected to do so on first use.The format of the buffer depends on the trace mode. When in PC tracing justthe return address of the probe is stored. Under comparison tracing thecomparison type, the two arguments, and the return address are traced. Theformer method uses on entry per trace event, while the later uses 4. Assuch they are incompatible so only a single mode may be enabled.KCOV is expected to help fuzzing the kernel, and while in development hasalready found a number of issues. It is required for the syzkaller systemcall fuzzer [1]. Other kernel fuzzers could also make use of it, eitherwith the current interface, or by extending it with new modes.A man page is currently being worked on and is expected to be committedsoon, however having the code in the kernel now is useful for otherdevelopers to use.[1] https://github.com/google/syzkallerSubmitted by: Mitchell Horne (Earlier version)Reviewed by: kibTesting by: tuexenSponsored by: DARPA, AFRLSponsored by: The FreeBSD Foundation (Mitchell Horne)Differential Revision: https://reviews.freebsd.org/D14599 List of files: /freebsd-13.1/tests/sys/kern/Makefile

Wed, 21 Mar 2018 01:15:45 +0000

Implement getrandom(2) and getentropy(3)The general idea here is to provide userspace programs with well-definedsources of entropy, in a fashion that doesn't require opening a new filedescriptor (ulimits) or accessing paths (/dev/urandom may be restrictedby chroot or capsicum).getrandom(2) is the more general API, and comes from the Linux world.Since our urandom and random devices are identical, the GRND_RANDOM flagis ignored.getentropy(3) is added as a compatibility shim for the OpenBSD API.truss(1) support is included.Tests for both system calls are provided. Coverage is believed to be atleast as comprehensive as LTP getrandom(2) test coverage. Additionally,instructions for running the LTP tests directly against FreeBSD are providedin the "Test Plan" section of the Differential revision linked below.
