Daniel Borkmann says: ==================== pull-request: bpf 2018-05-18 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Fix two bugs in sockmap, a use after free in sockmap's error path from sock_map_ctx_update_elem() where we mistakenly drop a reference we didn't take prior to that, and in the same function fix a race in bpf_prog_inc_not_zero() where we didn't use the progs from prior READ_ONCE(), from John. 2) Reject program expansions once we figure out that their jump target which crosses patchlet boundaries could otherwise get truncated in insn->off space, from Daniel. 3) Check the return value of fopen() in BPF selftest's test_verifier where we determine whether unpriv BPF is disabled, and iff we do fail there then just assume it is disabled. This fixes a segfault when used with older kernels, from Jesper. ==================== Signed-off-by: David S. Miller <davem@davemloft.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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
