Pull core entry/ptrace update from Thomas Gleixner: "Provide a ptrace set/get interface for syscall user dispatch. The main purpose is to enable checkpoint/restore (CRIU) to handle processes which utilize syscall user dispatch correctly" * tag 'core-entry-2023-04-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: selftest, ptrace: Add selftest for syscall user dispatch config api ptrace: Provide set/get interface for syscall user dispatch syscall_user_dispatch: Untag selector address before access_ok() syscall_user_dispatch: Split up set_syscall_user_dispatch()

selftest, ptrace: Add selftest for syscall user dispatch config api

2023-04-16T12:23:08+00:00

Validate that the following new ptrace requests work as expected * PTRACE_GET_SYSCALL_USER_DISPATCH_CONFIG returns the contents of task->syscall_dispatch * PTRACE_SET_SYSCALL_USER_DISPATCH_CONFIG sets the contents of task->syscall_dispatch Signed-off-by: Gregory Price Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/r/20230407171834.3558-5-gregory.price@memverge.com

selftests: Refactor 'peeksiginfo' ptrace test part

2023-03-28T16:23:45+00:00

peeksiginfo creates an array of 10 instances of 'siginfo_t', but actually uses only one. This patch will reduce amount of memory on the stack used by the peeksiginfo test. Signed-off-by: Ivan Orlov Signed-off-by: Shuah Khan

selftests: ptrace: Use installed kernel headers search path

2023-02-13T16:09:46+00:00

Use $(KHDR_INCLUDES) as lookup path for installed kernel headers rather than using kernel headers in include/uapi from the source kernel tree kernel headers. Signed-off-by: Mathieu Desnoyers Cc: Shuah Khan Cc: linux-kselftest@vger.kernel.org Cc: Ingo Molnar Signed-off-by: Shuah Khan

selftests: Add missing gitignore entries

Merge tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

2020-04-03T20:12:26+00:00

Pull SPDX updates from Greg KH: "Here are three SPDX patches for 5.7-rc1. One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.) All three of these have been in linux-next for a while, with no reported issues other than the merge conflict" * tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: ASoC: MT6660: make spdxcheck.py happy .gitignore: add SPDX License Identifier .gitignore: remove too obvious comments

selftests/ptrace: add test cases for dead-locks
