perf beauty prctl: Export the 'options' strarray

2020-02-11T19:41:50+00:00

So that we can use it with strtoul, allowing string to number conversions in filter expressions. Cc: Adrian Hunter Cc: Christian Brauner Cc: Jiri Olsa Cc: Mike Christie Cc: Namhyung Kim Signed-off-by: Arnaldo Carvalho de Melo

perf beauty sockaddr: Fix augmented syscall format warning

2020-01-14T15:42:26+00:00

The sockaddr related examples given in `tools/perf/examples/bpf/augmented_syscalls.c` almost always use `long`s to represent most of their fields. However, `size_t syscall_arg__scnprintf_sockaddr(..)` has a `scnprintf` call that uses `"%#x"` as format string. This throws a warning (whenever the syscall argument is `unsigned long`). Added `l` identifier to indicate that the `arg->value` is an unsigned long. Not sure about the complications of this with x86 though.

perf beauty: Add CLEAR_SIGHAND support for clone's flags arg

2019-12-02T18:19:52+00:00

Add support for the recently added CLONE_CLEAR_SIGHAND flag. This takes advantage of the copy of the uapi/linux/sched.h we have in tools/include, which allows us to build tools/perf in older systems and have the binary support printing that flag whenever that system gets its kernel updated to one where this feature is present.

perf trace: Wire up strarray__strtoul_flags()

2019-10-19T18:35:02+00:00

Now anything that uses STRARRAY_FLAGS, like the 'fsmount' syscall will support mapping or-ed strings back to a value that can be used in a filter. In some cases, where STRARRAY_FLAGS isn't used but instead the scnprintf is a special one because of specific needs, like for mmap, then one has to set the ->pars to the strarray. See the next cset.

libbeauty: Introduce strarray__strtoul_flags()

2019-10-19T18:35:02+00:00

Counterpart of strarray__scnprintf_flags(), i.e. from a expression like: # perf trace -e syscalls:sys_enter_mmap --filter="flags==PRIVATE|FIXED|DENYWRITE" I.e. that "flags==PRIVATE|FIXED|DENYWRITE", turn that into # perf trace -e syscalls:sys_enter_mmap --filter=0x812 Cc: Adrian Hunter Cc: Andi Kleen Cc: Brendan Gregg Cc: David Ahern Cc: Jiri Olsa Cc: Luis Cláudio Gonçalves Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-8xst3zrqqogax7fmfzwymvbl@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

libbeauty: Make the mmap_flags strarray visible outside of its beautifier

2019-10-19T18:35:02+00:00

So that we can later use it with the strarray__strtoul_flags() routine that will be soon introduced. Cc: Adrian Hunter Cc: Jiri Olsa Cc: Luis Cláudio Gonçalves Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-vldj3ch8su6i20to5eq31e8x@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

libbeauty: Introduce syscall_arg__strtoul_strarrays()

2019-10-19T18:35:01+00:00

To allow going from string to integer for 'struct strarrays'. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Luis Cláudio Gonçalves Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-b1ia3xzcy72hv0u4m168fcd0@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

libbeauty: Introduce syscall_arg__strtoul_strarray()

2019-10-18T15:07:46+00:00

To go from strarrays strings to its indexes. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Luis Cláudio Gonçalves Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-wta0qvo207z27huib2c4ijxq@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf trace beauty: Add the glue for the autogenerated x86 IRQ vector array

2019-10-15T19:13:27+00:00

We need to wrap this autogenerated string array with the strarray__scnprintf() formatter and the strarray__strotul() lookup method, do it.

libbeauty: Add a strarray__scnprintf_suffix() method

2019-10-15T19:01:42+00:00

In some cases, like with x86 IRQ vectors, the common part in names is at the end, so a suffix, add a scnprintf function for that.
