2021-02-03net: selftests: Add lanes setting testDanielle Ratson3-0/+249
Test that setting lanes parameter is working. Set max speed and max lanes in the list of advertised link modes, and then try to set max speed with the lanes below max lanes if exists in the list. And then, test that setting number of lanes larger than max lanes fails. Do the above for both autoneg on and off. $ ./ethtool_lanes.sh TEST: 4 lanes is autonegotiated [ OK ] TEST: Lanes number larger than max width is not set [ OK ] TEST: Autoneg off, 4 lanes detected during force mode [ OK ] TEST: Lanes number larger than max width is not set [ OK ] Signed-off-by: Danielle Ratson <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>

2021-02-03selftest/bpf: Testing for multiple logs on REJECTAndrei Matei1-3/+13
This patch adds support to verifier tests to check for a succession of verifier log messages on program load failure. This makes the errstr field work uniformly across REJECT and VERBOSE_ACCEPT checks. This patch also increases the maximum size of a message in the series of messages to test from 80 chars to 200 chars. This is in order to keep existing tests working, which sometimes test for messages larger than 80 chars (which was accepted in the REJECT case, when testing for a single message, but not in the VERBOSE_ACCEPT case, when testing for possibly multiple messages). And example of such a long, checked message is in bounds.c: "R1 has unknown scalar with mixed signed bounds, pointer arithmetic with it prohibited for !root" Signed-off-by: Andrei Matei <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Acked-by: Song Liu <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
2021-02-02selftests/bpf: Fix a compiler warning in local_storage testKP Singh1-1/+1
Some compilers trigger a warning when tmp_dir_path is allocated with a fixed size of 64-bytes and used in the following snprintf: snprintf(tmp_exec_path, sizeof(tmp_exec_path), "%s/copy_of_rm", tmp_dir_path); warning: ‘/copy_of_rm’ directive output may be truncated writing 11 bytes into a region of size between 1 and 64 [-Wformat-truncation=] This is because it assumes that tmp_dir_path can be a maximum of 64 bytes long and, therefore, the end-result can get truncated. Fix it by not using a fixed size in the initialization of tmp_dir_path which allows the compiler to track actual size of the array better.

2021-02-02bpf: Propagate stack bounds to registers in atomics w/ BPF_FETCHBrendan Jackman3-0/+66
When BPF_FETCH is set, atomic instructions load a value from memory into a register. The current verifier code first checks via check_mem_access whether we can access the memory, and then checks via check_reg_arg whether we can write into the register. For loads, check_reg_arg has the side-effect of marking the register's value as unkonwn, and check_mem_access has the side effect of propagating bounds from memory to the register. This currently only takes effect for stack memory. Therefore with the current order, bounds information is thrown away, but by simply reversing the order of check_reg_arg vs. check_mem_access, we can instead propagate bounds smartly. A simple test is added with an infinite loop that can only be proved unreachable if this propagation is present. This is implemented both with C and directly in test_verifier using assembly.

2021-01-31selftests/powerpc: Add VF recovery testsOliver O'Halloran3-0/+188
The basic EEH test ignores VFs since we the way the eeh_dev_break debugfs interface works means that if multiple VFs are enabled we may cause errors on all them them. However, we can work around that by only enabling a single VF at a time. This patch adds some infrastructure for finding SR-IOV capable devices and enabling / disabling VFs so we can exercise the VF specific EEH recovery paths. Two new tests are added, one for testing EEH aware devices and one for EEH un-aware VFs.

2021-01-29tools: Factor Clang, LLC and LLVM utils definitionsSedat Dilek2-4/+1
When dealing with BPF/BTF/pahole and DWARF v5 I wanted to build bpftool. While looking into the source code I found duplicate assignments in misc tools for the LLVM eco system, e.g. clang and llvm-objcopy. Move the Clang, LLC and/or LLVM utils definitions to tools/scripts/Makefile.include file and add missing includes where needed. Honestly, I was inspired by the commit c8a950d0d3b9 ("tools: Factor HOSTCC, HOSTLD, HOSTAR definitions"). I tested with bpftool and perf on Debian/testing AMD64 and LLVM/Clang v11.1.0-rc1.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - Fix a bad interaction between the scv handling and the fallback L1D flush, which could lead to user register corruption. Only affects people using scv (~no one) on machines with old firmware that are missing the L1D flush. - Two small selftest fixes. Thanks to Eirik Fuller, Libor Pechacek, Nicholas Piggin, Sandipan Das, and Tulio Magno Quites Machado Filho. * tag 'powerpc-5.11-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/64s: fix scv entry fallback flush vs interrupt selftests/powerpc: Only test lwm/stmw on big endian selftests/powerpc: Fix exit status of pkey tests
2021-01-24tests: add mount_setattr() selftestsChristian Brauner5-0/+1434
Add a range of selftests for the new mount_setattr() syscall to verify that it works as expected. This tests that: - no invalid flags can be specified - changing properties of a single mount works and leaves other mounts in the mount tree unchanged - changing a mount tre to read-only when one of the mounts has writers fails and leaves the whole mount tree unchanged - changing mount properties from multiple threads works - changing atime settings works - changing mount propagation works - changing the mount options of a mount tree where the individual mounts in the tree have different mount options only changes the flags that were requested to change - changing mount options from another mount namespace fails - changing mount options from another user namespace fails - idmapped mounts Note, the main test-suite for idmapped mounts is part of xfstests and is pretty huge. These tests here just make sure that the syscalls bits work correctly.
