Allow the BPF filter to use the uid and gid terms determined by the bpf_get_current_uid_gid BPF helper. For example, the following will record the cpu-clock event system wide discarding samples that don't belong to the current user. $ perf record -e cpu-clock --filter "uid == $(id -u)" -a sleep 0.1 Signed-off-by: Ian Rogers <irogers@google.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: John Fastabend <john.fastabend@gmail.com> Cc: Changbin Du <changbin.du@huawei.com> Cc: Yang Jihong <yangjihong1@huawei.com> Cc: Andrii Nakryiko <andrii@kernel.org> Cc: bpf@vger.kernel.org Signed-off-by: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20240524205227.244375-3-irogers@google.com
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 reStructuredText 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.
