Daniel Borkmann says: ==================== pull-request: bpf 2018-02-20 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Fix a memory leak in LPM trie's map_free() callback function, where the trie structure itself was not freed since initial implementation. Also a synchronize_rcu() was needed in order to wait for outstanding programs accessing the trie to complete, from Yonghong. 2) Fix sock_map_alloc()'s error path in order to correctly propagate the -EINVAL error in case of too large allocation requests. This was just recently introduced when fixing close hooks via ULP layer, fix from Eric. 3) Do not use GFP_ATOMIC in __cpu_map_entry_alloc(). Reason is that this will not work with the recent __ptr_ring_init_queue_alloc() conversion to kvmalloc_array(), where in case of fallback to vmalloc() that GFP flag is invalid, from Jason. 4) Fix two recent syzkaller warnings: i) fix bpf_prog_array_copy_to_user() when a prog query with a big number of ids was performed where we'd otherwise trigger a warning from allocator side, ii) fix a missing mlock precharge on arraymaps, from Daniel. 5) Two fixes for bpftool in order to avoid breaking JSON output when used in batch mode, from Quentin. 6) Move a pr_debug() in libbpf in order to avoid having an otherwise uninitialized variable in bpf_program__reloc_text(), from Jeremy. ==================== Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
