Update the set of sleepable hooks with the ones that do not trigger a warning with might_fault() when exercised with the correct kernel config options enabled, i.e. DEBUG_ATOMIC_SLEEP=y LOCKDEP=y PROVE_LOCKING=y This means that a sleepable LSM eBPF program can be attached to these LSM hooks. A new helper method bpf_lsm_is_sleepable_hook is added and the set is maintained locally in bpf_lsm.c Signed-off-by: KP Singh <kpsingh@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/bpf/20201113005930.541956-2-kpsingh@chromium.org
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.
