2024-08-13KVM: selftests: Add a testcase to verify x2APIC is fully readonlyMichal Luczaj
Add a test to verify that userspace can't change a vCPU's x2APIC ID by abusing KVM_SET_LAPIC. KVM models the x2APIC ID (and x2APIC LDR) as readonly, and silently ignores userspace attempts to change the x2APIC ID for backwards compatibility.

2024-08-12selftests/bpf: Add a test to verify previous stacksafe() fixYonghong Song
A selftest is added such that without the previous patch, a crash can happen. With the previous patch, the test can run successfully. The new test is written in a way which mimics original crash case: main_prog static_prog_1 static_prog_2 where static_prog_1 has different paths to static_prog_2 and some path has stack allocated and some other path does not. A stacksafe() checking in static_prog_2() triggered the crash.

Makefile.include can modify CC and CFLAGS for usage with clang. Make use of it. Makefile.include is currently used to handle the O= variable.

2024-08-12tools/nolibc: compiler: use attribute((naked)) if availableThomas Weißschuh
The current entrypoint attributes optimize("Os", "omit-frame-pointer") are intended to avoid all compiler generated code, like function porologue and epilogue. This is the exact usecase implemented by the attribute "naked". Unfortunately this is not implemented by GCC for all targets, so only use it where available. This also provides compatibility with clang, which recognizes the "naked" attribute but not the previously used attribute "optimized".

2024-08-10tools/nolibc: compiler: introduce __nolibc_has_attribute()Thomas Weißschuh
Recent compilers support __has_attribute() to check if a certain compiler attribute is supported. Unfortunately we have to first check if __has_attribute is supported in the first place and then if a specific attribute is present. These two checks can't be folded into a single condition as that would lead to errors. Nesting the two conditions like below works, but becomes ugly as soon as #else blocks are used as those need to be duplicated for both levels of #if. #if defined __has_attribute # if __has_attribute (nonnull) # define ATTR_NONNULL __attribute__ ((nonnull)) # endif #endif Introduce a new helper which makes the usage of __has_attribute() nicer and migrate the current user to it.

2024-08-08bpf/bpf_get,set_sockopt: add option to set TCP-BPF sock ops flagsAlan Maguire
Currently the only opportunity to set sock ops flags dictating which callbacks fire for a socket is from within a TCP-BPF sockops program. This is problematic if the connection is already set up as there is no further chance to specify callbacks for that socket. Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_setsockopt() and bpf_getsockopt() to allow users to specify callbacks later, either via an iterator over sockets or via a socket-specific program triggered by a setsockopt() on the socket.

2024-08-07selftests: mm: add s390 to ARCH checkNico Pache
commit 0518dbe97fe6 ("selftests/mm: fix cross compilation with LLVM") changed the env variable for the architecture from MACHINE to ARCH. This is preventing 3 required TEST_GEN_FILES from being included when cross compiling s390x and errors when trying to run the test suite. This is due to the ARCH variable already being set and the arch folder name being s390. Add "s390" to the filtered list to cover this case and have the 3 files included in the build.

2024-08-07tracing/selftests: Run the ownership test twiceSteven Rostedt (Google)
A regression happened where running the ownership test passes on the first iteration but fails running it a second time. This was caught and fixed, but a later change brought it back. The regression was missed because the automated tests only run the tests once per boot. Change the ownership test to iterate through the tests twice, as this will catch the regression with a single run.
