Daniel Borkmann says: ==================== pull-request: bpf-next 2020-06-02 The following pull-request contains BPF _fixes-only_ for your *net-next* tree. We've added 10 non-merge commits during the last 1 day(s) which contain a total of 15 files changed, 229 insertions(+), 74 deletions(-). The main changes are: 1) Several fixes to s390 BPF JIT e.g. fixing kernel panic when BPF stack is not 8-byte aligned, from Ilya Leoshkevich. 2) Fix bpf_skb_adjust_room() helper's CHECKSUM_UNNECESSARY handling which was wrongly bypassing TCP checksum verification, from Daniel Borkmann. 3) Fix tools/bpf/ build under MAKEFLAGS=rR which causes built-in CXX and others vars to be undefined, also from Ilya Leoshkevich. 4) Fix BPF ringbuf's selftest shared sample_cnt variable to avoid compiler optimizations on it, from Andrii Nakryiko. 5) Fix up test_verifier selftest due to addition of rx_queue_mapping to the bpf_sock structure, from Alexei Starovoitov. ==================== Signed-off-by: David S.

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.
