Not a false positive - dropped the lockdep fix for up_read_non_owner in bpf_get_stackid In addition to preempt_disable patch for socket filters https://patchwork.ozlabs.org/patch/1032437/ First patch fixes lockdep false positive in percpu_freelist Second patch fixes potential deadlock in bpf_prog_register Third patch fixes another potential deadlock in stackmap access from tracing bpf prog and from syscall. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
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.
