2024-10-17kselftest/arm64: mte: use proper SKIP syntaxAndre Przywara
If MTE is not available on a system, we detect this early and skip all the MTE selftests. However this happens before we print the TAP plan, so tools parsing the TAP output get confused and report an error. Use the existing ksft_exit_skip() function to handle this, which uses a dummy plan to work with tools expecting proper TAP syntax, as described in the TAP specification.

2024-10-17maple_tree: add regression test for spanning store bugLorenzo Stoakes
Add a regression test to assert that, when performing a spanning store which consumes the entirety of the rightmost right leaf node does not result in maple tree corruption when doing so. This achieves this by building a test tree of 3 levels and establishing a store which ultimately results in a spanned store of this nature.

2024-10-17maple_tree: check for MA_STATE_BULK on setting wr_rebalanceSidhartha Kumar
It is possible for a bulk operation (MA_STATE_BULK is set) to enter the new_end < mt_min_slots[type] case and set wr_rebalance as a store type. This is incorrect as bulk stores do not rebalance per write, but rather after the all of the writes are done through the mas_bulk_rebalance() path. Therefore, add a check to make sure MA_STATE_BULK is not set before we return wr_rebalance as the store type. Also add a test to make sure wr_rebalance is never the store type when doing bulk operations via mas_expected_entries() This is a hotfix for this rc however it has no userspace effects as there are no users of the bulk insertion mode.

2024-10-17selftests/mm: replace atomic_bool with pthread_barrier_tEdward Liaw
Patch series "selftests/mm: fix deadlock after pthread_create". On Android arm, pthread_create followed by a fork caused a deadlock in the case where the fork required work to be completed by the created thread. Update the synchronization primitive to use pthread_barrier instead of atomic_bool. Apply the same fix to the wp-fork-with-event test. This patch (of 2): Swap synchronization primitive with pthread_barrier, so that stdatomic.h does not need to be included. The synchronization is needed on Android ARM64; we see a deadlock with pthread_create when the parent thread races forward before the child has a chance to start doing work.

The original commit that brought VDSO support into powerpc/64 has the following explanation: Note that the symbols exposed by the vDSO aren't "normal" function symbols, apps can't be expected to link against them directly, the vDSO's are both seen as if they were linked at 0 and the symbols just contain offsets to the various functions. This is done on purpose to avoid a relocation step (ppc64 functions normally have descriptors with abs addresses in them). When glibc uses those functions, it's expected to use it's own trampolines that know how to reach them. The descriptors it's talking about are the OPD function descriptors used on ABI v1 (big endian). But it would be more correct for a text symbol to have type function, even if there's no function descriptor for it. glibc has a special case already for handling the VDSO symbols which creates a fake opd pointing at the kernel symbol. So changing the VDSO symbol type to function shouldn't affect that. For ABI v2, there is no function descriptors and VDSO functions can safely have function type. So lets flag VDSO entry points as functions and revert the selftest change.

2024-10-14Merge patch series "ovl: file descriptors based layer setup"Christian Brauner
Christian Brauner <brauner@kernel.org> says: Currently overlayfs only allows specifying layers through path names. This is inconvenient for users such as systemd that want to assemble an overlayfs mount purely based on file descriptors. When porting overlayfs to the new mount api I already mentioned this. This enables user to specify both: fsconfig(fd_overlay, FSCONFIG_SET_FD, "upperdir+", NULL, fd_upper); fsconfig(fd_overlay, FSCONFIG_SET_FD, "workdir+", NULL, fd_work); fsconfig(fd_overlay, FSCONFIG_SET_FD, "lowerdir+", NULL, fd_lower1); fsconfig(fd_overlay, FSCONFIG_SET_FD, "lowerdir+", NULL, fd_lower2); in addition to: fsconfig(fd_overlay, FSCONFIG_SET_STRING, "upperdir+", "/upper", 0); fsconfig(fd_overlay, FSCONFIG_SET_STRING, "workdir+", "/work", 0); fsconfig(fd_overlay, FSCONFIG_SET_STRING, "lowerdir+", "/lower1", 0); fsconfig(fd_overlay, FSCONFIG_SET_STRING, "lowerdir+", "/lower2", 0); The selftest contain an example for this. * patches from https://lore.kernel.org/r/20241014-work-overlayfs-v3-0-32b3fed1286e@kernel.org: selftests: add overlayfs fd mounting selftests selftests: use shared header Documentation,ovl: document new file descriptor based layers ovl: specify layers via file descriptors fs: add helper to use mount option as path or fd Link: https://lore.kernel.org/r/20241014-work-overlayfs-v3-0-32b3fed1286e@kernel.org Signed-off-by: Christian Brauner <brauner@kernel.org>
