Daniel Borkmann says: ==================== pull-request: bpf-next 2021-01-16 1) Extend atomic operations to the BPF instruction set along with x86-64 JIT support, that is, atomic{,64}_{xchg,cmpxchg,fetch_{add,and,or,xor}}, from Brendan Jackman. 2) Add support for using kernel module global variables (__ksym externs in BPF programs) retrieved via module's BTF, from Andrii Nakryiko. 3) Generalize BPF stackmap's buildid retrieval and add support to have buildid stored in mmap2 event for perf, from Jiri Olsa. 4) Various fixes for cross-building BPF sefltests out-of-tree which then will unblock wider automated testing on ARM hardware, from Jean-Philippe Brucker. 5) Allow to retrieve SOL_SOCKET opts from sock_addr progs, from Daniel Borkmann. 6) Clean up driver's XDP buffer init and split into two helpers to init per- descriptor and non-changing fields during processing, from Lorenzo Bianconi. 7) Minor misc improvements to libbpf & bpftool, from Ian Rogers. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (41 commits) perf: Add build id data in mmap2 event bpf: Add size arg to build_id_parse function bpf: Move stack_map_get_build_id into lib bpf: Document new atomic instructions bpf: Add tests for new BPF atomic operations bpf: Add bitwise atomic instructions bpf: Pull out a macro for interpreting atomic ALU operations bpf: Add instructions for atomic_[cmp]xchg bpf: Add BPF_FETCH field / create atomic_fetch_add instruction bpf: Move BPF_STX reserved field check into BPF_STX verifier code bpf: Rename BPF_XADD and prepare to encode other atomics in .imm bpf: x86: Factor out a lookup table for some ALU opcodes bpf: x86: Factor out emission of REX byte bpf: x86: Factor out emission of ModR/M for *(reg + off) tools/bpftool: Add -Wall when building BPF programs bpf, libbpf: Avoid unused function warning on bpf_tail_call_static selftests/bpf: Install btf_dump test cases selftests/bpf: Fix installation of urandom_read selftests/bpf: Move generated test files to $(TEST_GEN_FILES) selftests/bpf: Fix out-of-tree build ... ==================== Link: https://lore.kernel.org/r/20210116012922.17823-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-01-14bpf: Rename BPF_XADD and prepare to encode other atomics in .immBrendan Jackman
A subsequent patch will add additional atomic operations. These new operations will use the same opcode field as the existing XADD, with the immediate discriminating different operations. In preparation, rename the instruction mode BPF_ATOMIC and start calling the zero immediate BPF_ADD. This is possible (doesn't break existing valid BPF progs) because the immediate field is currently reserved MBZ and BPF_ADD is zero. All uses are removed from the tree but the BPF_XADD definition is kept around to avoid breaking builds for people including kernel headers.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net Pull networking fixes from Jakub Kicinski: "We have a few fixes for long standing issues, in particular Eric's fix to not underestimate the skb sizes, and my fix for brokenness of register_netdevice() error path. They may uncover other bugs so we will keep an eye on them. Also included are Willem's fixes for kmap(_atomic). Looking at the "current release" fixes, it seems we are about one rc behind a normal cycle.

2021-01-14net: Allow NETIF_F_HW_TLS_TX if IP_CSUM && IPV6_CSUMTariq Toukan
Cited patch below blocked the TLS TX device offload unless HW_CSUM is set. This broke devices that use IP_CSUM && IP6_CSUM. Here we fix it. Note that the single HW_TLS_TX feature flag indicates support for both IPv4/6, hence it should still be disabled in case only one of (IP_CSUM | IPV6_CSUM) is set.

2021-01-07dt-bindings: net: dwmac-meson: use picoseconds for the RGMII RX delayMartin Blumenstingl
Amlogic Meson G12A, G12B and SM1 SoCs have a more advanced RGMII RX delay register which allows picoseconds precision. Deprecate the old "amlogic,rx-delay-ns" in favour of the generic "rx-internal-delay-ps" property. For older SoCs the only known supported values were 0ns and 2ns. The new SoCs have support for RGMII RX delays between 0ps and 3000ps in 200ps steps. Don't carry over the description for the "rx-internal-delay-ps" property and inherit that from ethernet-controller.yaml instead.

2021-01-07docs: remove mention of ENABLE_MUST_CHECKMiguel Ojeda
We removed ENABLE_MUST_CHECK in 196793946264 ("Compiler Attributes: remove CONFIG_ENABLE_MUST_CHECK"), so let's remove docs' mentions. At the same time, fix the outdated text related to ENABLE_WARN_DEPRECATED that wasn't removed in 3337d5cfe5e08 ("configs: get rid of obsolete CONFIG_ENABLE_WARN_DEPRECATED"). Finally, reflow the paragraph.

Before commit 889b8f964f2f ("packet: Kill CONFIG_PACKET_MMAP.") there used to be a CONFIG_PACKET_MMAP config symbol that depended on CONFIG_PACKET. The text still implies that PACKET_MMAP can be disabled. Remove that from the text, as well as reference to old kernel versions. Also, drop reference to broken link to information for pre 2.6.5 kernels. Make a slight working improvement (s/In/On/) while at it.

2020-12-31docs: Fix reST markup when linking to sectionsNícolas F. R. A. Prado
During the process of converting the documentation to reST, some links were converted using the following wrong syntax (and sometimes using %20 instead of spaces): `Display text <#section-name-in-html>`__ This syntax isn't valid according to the docutils' spec [1], but more importantly, it is specific to HTML, since it uses '#' to link to an HTML anchor. The right syntax would instead use a docutils hyperlink reference as the embedded URI to point to the section [2], that is: `Display text <Section Name_>`__ This syntax works in both HTML and PDF. The LaTeX toolchain doesn't mind the HTML anchor syntax when generating the pdf documentation (make pdfdocs), that is, the build succeeds but the links don't work, but that syntax causes errors when trying to build using the not-yet-merged rst2pdf: ValueError: format not resolved, probably missing URL scheme or undefined destination target for 'Forcing%20Quiescent%20States' So, use the correct syntax in order to have it work in all different output formats.
