| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the AIA ONE_REG registers are reported by get-reg-list as new registers for various vcpu_reg_list configs whenever Ssaia is available on the host because Ssaia extension can only be disabled by Smstateen extension which is not always available. To tackle this, we should filter-out AIA ONE_REG registers only when Ssaia can't be disabled for a VCPU.

| | * KVM: riscv: selftests: Fix ISA_EXT register handling in get-reg-listAnup Patel2023-09-211-14/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Same set of ISA_EXT registers are not present on all host because ISA_EXT registers are visible to the KVM user space based on the ISA extensions available on the host. Also, disabling an ISA extension using corresponding ISA_EXT register does not affect the visibility of the ISA_EXT register itself. Based on the above, we should filter-out all ISA_EXT registers.

If using LD_PRELOAD, those listed libraries will be loaded before the libraries listed in the program's ELF and will therefore violate this requirement, leading to the below failure and output from ASan. commit 58e2847ad2e6 ("selftests: line buffer test program's stdout") modified the kselftest runner to force line buffering by forcing the test programs to run through `stdbuf`. It turns out that stdbuf implements line buffering by injecting a library via LD_PRELOAD. Therefore selftests that use ASan started failing. Fix this by statically linking libasan in the affected test programs, using the `-static-libasan` option. Note this is already the default for Clang, but not got GCC. Test output sample for failing case: TAP version 13 1..3 # timeout set to 300 # selftests: openat2: openat2_test # ==4052==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. not ok 1 selftests: openat2: openat2_test # exit=1 # timeout set to 300 # selftests: openat2: resolve_test # ==4070==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. not ok 2 selftests: openat2: resolve_test # exit=1 Link: https://lkml.kernel.org/r/20230912135048.1755771-1-ryan.roberts@arm.com Signed-off-by: Ryan Roberts <ryan.roberts@arm.com> Fixes: 58e2847ad2e6 ("selftests: line buffer test program's stdout") Reported-by: kernel test robot <oliver.sang@intel.com> Closes: https://lore.kernel.org/oe-lkp/202309121342.97e2f008-oliver.sang@intel.com Cc: David Hildenbrand <david@redhat.com> Cc: Florent Revest <revest@chromium.org> Cc: Jérôme Glisse <jglisse@redhat.com> Cc: John Hubbard <jhubbard@nvidia.com> Cc: Mark Brown <broonie@kernel.org> Cc: Peter Xu <peterx@redhat.com> Cc: Shuah Khan <shuah@kernel.org> Cc: Tom Rix <trix@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

Add __LINE__ number suffix to make BTF_ID symbol more unique, which is not a complete fix, but it would help for now and meanwhile we can work on better solution as suggested by Andrii.

This rule deletion support does not make sense and userspace does not use this. Problem exists since the introduction of chain binding support. 2) rbtree GC worker only collects the elements that have expired. This operation is not destructive, therefore, turn write into read spinlock to avoid datapath contention due to GC worker run. This was not fixed in the recent GC fix batch in the 6.5 cycle. 3) pipapo set backend performs sync GC, therefore, catchall elements must use sync GC queue variant. This bug was introduced in the 6.5 cycle with the recent GC fixes. 4) Stop GC run if memory allocation fails in pipapo set backend, otherwise access to NULL pointer to GC transaction object might occur. This bug was introduced in the 6.5 cycle with the recent GC fixes. 5) rhash GC run uses an iterator that might hit EAGAIN to rewind, triggering double-collection of the same element. This bug was introduced in the 6.5 cycle with the recent GC fixes. 6) Do not permit to remove elements in anonymous sets, this type of sets are populated once and then bound to rules. This fix is similar to the chain binding patch coming first in this batch. API permits since the very beginning but it has no use case from userspace. ==================== Signed-off-by: David S.

That is, If a event file is opened for an instance, there's nothing preventing the instance from being removed which will make accessing the files cause use-after-free bugs. - Fix a ring buffer race that happens when iterating over the ring buffer while writers are active. Check to make sure not to read the event meta data if it's beyond the end of the ring buffer sub buffer. - Fix the print trigger that disappeared because the test to create it was looking for the event dir field being filled, but now it has the "ef" field filled for the eventfs structure. - Remove the unused "dir" field from the event structure. - Fix the order of the trace_dynamic_info as it had it backwards for the offset and len fields for which one was for which endianess. - Fix NULL pointer dereference with eventfs_remove_rec() If an allocation fails in one of the eventfs_add_*() functions, the caller of it in event_subsystem_dir() or event_create_dir() assigns the result to the structure. But it's assigning the ERR_PTR and not NULL. This was passed to eventfs_remove_rec() which expects either a good pointer or a NULL, not ERR_PTR. The fix is to not assign the ERR_PTR to the structure, but to keep it NULL on error. - Fix list_for_each_rcu() to use list_for_each_srcu() in dcache_dir_open_wrapper(). One iteration of the code used RCU but because it had to call sleepable code, it had to be changed to use SRCU, but one of the iterations was missed. - Fix synthetic event print function to use "as_u64" instead of passing in a pointer to the union. To fix big/little endian issues, the u64 that represented several types was turned into a union to define the types properly. * tag 'trace-v6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: eventfs: Fix the NULL pointer dereference bug in eventfs_remove_rec() tracefs/eventfs: Use list_for_each_srcu() in dcache_dir_open_wrapper() tracing/synthetic: Print out u64 values properly tracing/synthetic: Fix order of struct trace_dynamic_info selftests/ftrace: Fix dependencies for some of the synthetic event tests tracing: Remove unused trace_event_file dir field tracing: Use the new eventfs descriptor for print trigger ring-buffer: Do not attempt to read past "commit" tracefs/eventfs: Free top level files on removal ring-buffer: Avoid softlockup in ring_buffer_resize() tracing: Have event inject files inc the trace array ref count tracing: Have option files inc the trace array ref count tracing: Have current_trace inc the trace array ref count tracing: Have tracing_max_latency inc the trace array ref count tracing: Increase trace array ref count on enable and filter files tracefs/eventfs: Use dput to free the toplevel events directory tracefs/eventfs: Add missing lockdown checks tracefs: Add missing lockdown check to tracefs_create_dir()

This causes some of the tests to exit as unsupported. Fix this by changing the grep pattern. Since we want these tests to work on older kernels, match only against the common last part of the pattern.

Extra care is needed for tests that have symlinks. Commit ae108c48b5d2 ("selftests: net: Fix cross-tree inclusion of scripts") added '-L' (transform symlink into referent file/dir) to rsync, to fix dangling links. However, that broke some tests where the symlink (being a symlink) is part of the test (e.g. exec:execveat). Use rsync's '--copy-unsafe-links' that does right thing.

Without the "foreground" option, it is not possible for a user to cancel the runner using SIGINT, because the signal is not propagated to timeout which is running in a different process group. The "forground" options places the timeout in the same process group as its parent, but only sends the SIGTERM (on timeout) signal to the forked process. Unfortunately, this does not play nice with all kselftests, e.g. "net:fcnal-test.sh", where the child processes will linger because timeout does not send SIGTERM to the group. Some users have noted these hangs [1]. Fix this by nesting the timeout with an additional timeout without the foreground option.
