2023-09-15crypto: ccp - Fix sample application signature passingMario Limonciello
When parameters are sent the PSP returns back it's own signature for the application to verify the authenticity of the result. Display this signature to the caller instead of the one the caller sent.

2023-09-15crypto: ccp - Fix DBC sample application error handlingMario Limonciello
The sample application was taking values from ioctl() and treating those as the error codes to present to a user. This is incorrect when ret is non-zero, the error is stored to `errno`. Use this value instead.

tls.sendmsg_large and tls.sendmsg_multiple are trying to send through the self->cfd socket (only configured with TLS_RX) and to receive through the self->fd socket (only configured with TLS_TX), so they're not using kTLS at all.

2023-09-14selftests/thermel/intel: Add test to read workload hintSrinivas Pandruvada
Some SoCs have in built firmware support to classify current running workload and pass to OS for making power management decisions.

2023-09-14selftests/xsk: fail single test instead of all testsMagnus Karlsson
In a number of places at en error, exit_with_error() is called that terminates the whole test suite. This is not always desirable as it would be more logical to only fail that test and then go along with the other ones. So change this in a number of places in which I thought it would be more logical to just fail the test in question. Examples of this are in code that is only used by a single test. Also delete a pointless if-statement in receive_pkts() that has an exit_with_error() in it. It can never occur since the return value is an unsigned and the test is for less than zero.

2023-09-14selftests/xsk: print per packet info in verbose modeMagnus Karlsson
Print info about every packet in verbose mode, both for Tx and Rx. This is useful to have when a test fails or to validate that a test is really doing what it was designed to do. Info on what is supposed to be received and sent is also printed for the custom packet streams since they differ from the base line. Here is an example: Tx addr: 37e0 len: 64 options: 0 pkt_nb: 8 Tx addr: 4000 len: 64 options: 0 pkt_nb: 9 Rx: addr: 100 len: 64 options: 0 pkt_nb: 0 valid: 1 Rx: addr: 1100 len: 64 options: 0 pkt_nb: 1 valid: 1 Rx: addr: 2100 len: 64 options: 0 pkt_nb: 4 valid: 1 Rx: addr: 3100 len: 64 options: 0 pkt_nb: 8 valid: 1 Rx: addr: 4100 len: 64 options: 0 pkt_nb: 9 valid: 1 One pointless verbose print statement is also deleted and another one is made clearer.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Add missing LOCKDOWN checks for eventfs callers When LOCKDOWN is active for tracing, it causes inconsistent state when some functions succeed and others fail. - Use dput() to free the top level eventfs descriptor There was a race between accesses and freeing it. - Fix a long standing bug that eventfs exposed due to changing timings by dynamically creating files. 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()

2023-09-12perf tools: Add includes for detected configs in Makefile.perfAthira Rajeev
Makefile.perf uses "CONFIG_*" checks in the code. Example the config for libtraceevent is used to set PYTHON_EXT_SRCS ifeq ($(CONFIG_LIBTRACEEVENT),y) PYTHON_EXT_SRCS := $(shell grep -v ^\# util/python-ext-sources) else PYTHON_EXT_SRCS := $(shell grep -v '^\#\|util/trace-event.c' util/python-ext-sources) endif But this is not picking the value for CONFIG_LIBTRACEEVENT that is set using the settings in Makefile.config. Include the file ".config-detected" so that make will use the system detected configuration in the CONFIG checks. This will fix isues that could arise when other "CONFIG_*" checks are added to Makefile.perf in future as well.

The CPU ID in test__expr() has to be changed to perf_pmu__getcpuid() which returns the CPU ID string, rather than the raw CPU ID that get_cpuid() returns because that can't be used with strcmp_cpuid_str().

2023-09-12perf test: Check result of has_event(cycles) testJames Clark
Currently the function always returns 0, so even when the has_event() test fails, the test still passes. Fix it by returning ret instead.

2023-09-12perf list pfm: Retry supported test with exclude_kernelIan Rogers
With paranoia set at 2 evsel__open will fail with EACCES for non-root users. To avoid this stopping libpfm4 events from being printed, retry with exclude_kernel enabled - copying the regular is_event_supported test.
