- Implement BPF based syscall filtering in 'perf trace', using BPF maps and the augmented_raw_syscalls.c BPF proggie (Arnaldo Carvalho de Melo) - Allow specifying in .perfconfig a set of events use in 'perf trace' in addition to any other specified from the command line. This initially will be used to always use the augmented_raw_syscalls.o precompiled BPF program for getting pointer contents. (Arnaldo Carvalho de Melo) - Allow fine grained control about how the syscall output should be formatted. This will be used to allow producing the same output produced by the 'strace' tool, to then use in regression tests comparing the output of 'perf trace' with the one produced from 'strace' (Arnaldo Carvalho de Melo) - Beautify the renameat2 olddirfd, newdirfd and flags arguments (Arnaldo Carvalho de Melo) - Beautify arch_prctl 'code' syscall arg (Arnaldo Carvalho de Melo) - Beautify fadvise64 'advice' syscall arg (Arnaldo Carvalho de Melo) - Relax checks on perf-PID.map ownership, resulting in symbols in executable anonymous maps setup by JITs in things like node.js to be resolved in a 'perf top' session run by root without the need for --force to be used (Arnaldo Carvalho de Melo) - Update asm-generic/unistd.h copy (Arnaldo Carvalho de Melo) - Do not use the first and last symbols when setting up address filters in auxtrace, this fails when we don't have a symbol table, filter the entire area based on the dso size. (Adrian Hunter) - Do not use kernel headers to build libsubcmd, we shouldn't use anything from outside tools/, fixes the build with the Android NDK (Arnaldo Carvalho de Melo) - Add several prototypes for systems lacking those, such as open_memstream(), sigqueue(), fixing warnings building with Android's bionic libc that were preventing the use of -Werror there (Arnaldo Carvalho de Melo) - Use LDFLAGS in the libtraceevent build commands, allowing developers to override its values (Jiri Olsa) - Link libperf-jvmti.so with LDFLAGS variable, allowing distro packages to propagate its settings when building this library (Jiri Olsa) - cs-etm (ARM CoreSight) fixes: (Leo Yan) - Correct packets swapping in cs_etm__flush() - Avoid stale branch samples when flush packet - Remove unused 'trace_on' in cs_etm_decoder - Refactor enumeration cs_etm_sample_type - Rename CS_ETM_TRACE_ON to CS_ETM_DISCONTINUITY - Treat NO_SYNC element as trace discontinuity - Treat EO_TRACE element as trace discontinuity - Generate branch sample for exception packet - Use shebangs in the 'perf test' shell scripts, making them identifiable as shell scripts (Michael Petlan) - Avoid segfaults caused by negated options in 'perf stat' (Michael Petlan) - Fix processing of dereferenced args in bprintk events in libtracevent (Steven Rostedt) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQR2GiIUctdOfX2qHhGyPKLppCJ+JwUCXBluNgAKCRCyPKLppCJ+ J9bDAP9aHQ/33R1W0FTa9MFUosp2g8Qki1eFlNyC1mfTBk66sgD/TynpNQLadlmS nqUg3kG5oZK+npwDCyZ0RfAVvOyFXQQ= =hF7Q -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-4.21-20181218' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: - Implement BPF based syscall filtering in 'perf trace', using BPF maps and the augmented_raw_syscalls.c BPF proggie (Arnaldo Carvalho de Melo) - Allow specifying in .perfconfig a set of events use in 'perf trace' in addition to any other specified from the command line.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
