[ Upstream commit60e5ca8a64] Add missed bpf_map_charge_init() in sock_hash_alloc() and correspondingly bpf_map_charge_finish() on ENOMEM. It was found accidentally while working on unrelated selftest that checks "map->memory.pages > 0" is true for all map types. Before: # bpftool m l ... 3692: sockhash name m_sockhash flags 0x0 key 4B value 4B max_entries 8 memlock 0B After: # bpftool m l ... 84: sockmap name m_sockmap flags 0x0 key 4B value 4B max_entries 8 memlock 4096B Fixes:604326b41a("bpf, sockmap: convert to generic sk_msg interface") Signed-off-by: Andrey Ignatov <rdna@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/20200612000857.2881453-1-rdna@fb.com Signed-off-by: Sasha Levin <sashal@kernel.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.
