* syzkaller: Fix appends overriding valuesMichal Sieron2026-04-011-2/+2
| | | | | | | | Those LIC_FILES_CHKSUM:class-native(sdk) were actually overriding the rest of LIC_FILES_CHKSUM. Signed-off-by: Michal Sieron <michalwsieron@gmail.com> Signed-off-by: Khem Raj <khem.raj@oss.qualcomm.com>

* syzkaller: Upgrade to latest tip of trunkStefan Wiehler2025-08-146-146/+180
| | | | | | | | | | | | | | | | | | - All patches have been upstreamed - Add Go module dependencies to allow offline builds since upstream does not vendor them into the repo anymore - In accordance to upstream, disable cgo as we are unable to compile with it on all supported architectures; in addition, remove -linkshared and -buildmode=pie as it requires external (cgo) linking (the latter only on ARM and x86). Binary size hardly matters here as syzkaller is unlikely to be shipped in a production environment. - Add missing metadata and comply with style guide - Mark musl as incompatible as it does not provide the Memory Protection Keys API; in addition, there seems to be no intention from upstream to support anything besides glibc Signed-off-by: Stefan Wiehler <me@sephalon.net> Signed-off-by: Khem Raj <raj.khem@gmail.com>

* syzkaller: add recipe and selftest for syzkaller fuzzingOvidiu Panait2022-10-212-0/+140
Syzkaller is a coverage-guided fuzzer that is widely used to find bugs in the Linux kernel: https://github.com/google/syzkaller Add the recipe and a selftest for running the fuzzer in a qemux86-64 kvm environment. The following steps can be used to start the test: """ cat >> conf/local.conf <<EOF SYZ_WORKDIR="<path>" SYZ_FUZZTIME="30" SYZ_QEMU_VM_COUNT="2" SYZ_QEMU_MEM="2048" SYZ_QEMU_CPUS="2" EOF oe-selftest -r syzkaller ... loading corpus... serving http on http://127.0.0.1:49605 serving rpc on tcp://[::]:46475 booting test machines... wait for the connection from test machine... vm-0: crash: KCSAN: data-race in poll_schedule_timeout.constprop.NUM / pollwake vm-1: crash: KCSAN: data-race in mutex_spin_on_owner machine check: syscalls : 2227/4223 code coverage : enabled comparison tracing : enabled extra coverage : enabled delay kcov mmap : mmap returned an invalid pointer setuid sandbox : enabled namespace sandbox : enabled Android sandbox : /sys/fs/selinux/policy does not exist fault injection : enabled leak checking : enabled net packet injection : enabled net device setup : enabled concurrency sanitizer : enabled devlink PCI setup : PCI device 0000:00:10.0 is not available USB emulation : enabled hci packet injection : enabled wifi device emulation : enabled 802.15.4 emulation : enabled corpus : 0 (deleted 0 broken) seeds : 0/0 VMs 2, executed 1, cover 0, signal 0/0, crashes 2, repro 0 vm-1: crash: KCSAN: data-race in mutex_spin_on_owner """ This will fuzz the yocto kernel for 30 minutes using 2 qemu VMs, each VM getting 2048MB of memory and 2 CPUs. The path in SYZ_WORKDIR must be an absolute path that is persistent across oe-selftest runs, so that fuzzing does not start all over again on each invocation. Syzkaller will save the corpus database in that directory and will use the database to keep track of the interfaces already fuzzed. After the test is done, <workdir>/crashes directory will contain the report files for all the bugs found.
