Andrii Nakryiko says: ==================== This patch set fixes bug in CO-RE relocation candidate finding logic, which currently allows matching against forward declarations, functions, and other named types, even though it makes no sense to even attempt. As part of verifying the fix, add test using vmlinux.h with preserve_access_index attribute and utilizing struct pt_regs heavily to trace nanosleep syscall using 5 different types of tracing BPF programs. This test also demonstrated problems using struct pt_regs in syscall tracepoints and required a new set of macro, which were added in patch #3 into bpf_tracing.h. Patch #1 fixes annoying issue with selftest failure messages being out of sync. v1->v2: - drop unused handle__probed() function (Martin). ==================== 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.
