2021-01-13selftests/bpf: Install btf_dump test casesJean-Philippe Brucker1-1/+2
The btf_dump test cannot access the original source files for comparison when running the selftests out of tree, causing several failures: awk: btf_dump_test_case_syntax.c: No such file or directory ...

2021-01-12selftests/bpf: Sync RCU before unloading bpf_testmodAndrii Nakryiko3-33/+12
If some of the subtests use module BTFs through ksyms, they will cause bpf_prog to take a refcount on bpf_testmod module, which will prevent it from successfully unloading. Module's refcnt is decremented when bpf_prog is freed, which generally happens in RCU callback. So we need to trigger syncronize_rcu() in the kernel, which can be achieved nicely with membarrier(MEMBARRIER_CMD_SHARED) or membarrier(MEMBARRIER_CMD_GLOBAL) syscall. So do that in kernel_sync_rcu() and make it available to other test inside the test_progs. This synchronize_rcu() is called before attempting to unload bpf_testmod.

2021-01-12rcutorture: Add rcutree.use_softirq=0 to RUDE01 and TASKS01Paul E. McKenney2-0/+2
RCU's rcutree.use_softirq=0 kernel boot parameter substitutes the per-CPU rcuc kthreads for softirq, which is used in real-time installations. However, none of the rcutorture scenarios test this parameter. This commit therefore adds rcutree.use_softirq=0 to the RUDE01 and TASKS01 rcutorture scenarios, both of which indirectly exercise RCU.

2021-01-12bpf: Update local storage test to check handling of null ptrsKP Singh2-97/+61
It was found in [1] that bpf_inode_storage_get helper did not check the nullness of the passed owner ptr which caused an oops when dereferenced. This change incorporates the example suggested in [1] into the local storage selftest. The test is updated to create a temporary directory instead of just using a tempfile. In order to replicate the issue this copied rm binary is renamed tiggering the inode_rename with a null pointer for the new_inode. The logic to verify the setting and deletion of the inode local storage of the old inode is also moved to this LSM hook. The change also removes the copy_rm function and simply shells out to copy files and recursively delete directories and consolidates the logic of setting the initial inode storage to the bprm_committed_creds hook and removes the file_open hook.

Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change. These tests explicitly test for a recently discovered problem in the IPv6 routing framework where PMTU exceptions were not properly released when replacing a route via "ip route change ...". After creating PMTU exceptions, the route from the device A to R1 will be replaced with a new route, then device A will be deleted. If the PMTU exceptions were properly cleaned up by the kernel, this device deletion will succeed. Otherwise, the unregistration of the device will stall, and messages such as the following will be logged in dmesg: unregister_netdevice: waiting for veth_A-R1 to become free.

2021-01-06torture: Compress KASAN vmlinux filesPaul E. McKenney1-2/+46
The sizes of vmlinux files built with KASAN enabled can approach a full gigabyte, which can result in disk overflow sooner rather than later. Fortunately, the xz command compresses them by almost an order of magnitude. This commit therefore uses xz to compress vmlinux file built by torture.sh with KASAN enabled. However, xz is not the fastest thing in the world. In fact, it is way slower than rotating-rust mass storage. This commit therefore also adds a --compress-kasan-vmlinux argument to specify the degree of xz concurrency, which defaults to using all available CPUs if there are that many files in need of compression.

The bash "eval" command enables Bobby Tables attacks, which might not be a concern in torture testing by themselves, but one could imagine these combined with a cut-and-paste attack.

2021-01-05selftests: fix the return value for UDP GRO testPo-Hsu Lin1-0/+34
The udpgro.sh will always return 0 (unless the bpf selftest was not build first) even if there are some failed sub test-cases. Therefore the kselftest framework will report this case is OK. Check and return the exit status of each test to make it easier to spot real failures. Signed-off-by: Po-Hsu Lin <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2021-01-05torture: Do Kconfig analysis only once per scenarioPaul E. McKenney1-7/+15
Currently, if a scenario is repeated as in "--configs '4*TREE01'", the Kconfig analysis is performed for each occurrance (four times in this example) and each analysis places the exact same data into the exact same files. This is not really an issue in this repetition-four example, but it can needlessly consume tens of seconds of wallclock time for something like "--config '128*TINY01'". This commit therefore does Kconfig analysis only once per set of repeats of a given scenario, courtesy of the "sort -u" command and an automatically generated awk script. While in the area, this commit also wordsmiths a comment. Signed-off-by: Paul E. McKenney <[email protected]>
