Hi David, hi Jakub, hi Paolo, hi Eric, The following pull-request contains BPF updates for your *net-next* tree. We've added 260 non-merge commits during the last 36 day(s) which contain a total of 356 files changed, 21786 insertions(+), 11275 deletions(-). There is a simple merge conflict in include/net/ip_tunnels.h between net-next commit bc9d003dc48c ("ip_tunnel: Preserve pointer const in ip_tunnel_info_opts") and bpf-next commit ac931d4cdec3 ("ipip,ip_tunnel,sit: Add FOU support for externally controlled ipip devices"), resolution is to take both hunks: [...] /* Maximum tunnel options length. */ #define IP_TUNNEL_OPTS_MAX \ GENMASK((sizeof_field(struct ip_tunnel_info, \ options_len) * BITS_PER_BYTE) - 1, 0) #define ip_tunnel_info_opts(info) \ _Generic(info, \ const struct ip_tunnel_info * : ((const void *)((info) + 1)),\ struct ip_tunnel_info * : ((void *)((info) + 1))\ ) struct ip_tunnel_info { [...] Another small one in Documentation/bpf/bpf_devel_QA.rst between net-next commit b7abcd9c656b ("bpf, doc: Link to submitting-patches.rst for general patch submission info") and bpf-next commit 0f10f647f455 ("bpf, docs: Use internal linking for link to netdev subsystem doc"), resolve by removing both hunks: [...] .. Links .. _selftests: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/testing/selftests/bpf/ [...] And the last one concerns a small conflict in net/bpf/test_run.c between net-next commit 294635a8165a ("bpf, test_run: fix &xdp_frame misplacement for LIVE_FRAMES") and bpf-next commit e5995bc7e2ba ("bpf, test_run: fix crashes due to XDP frame overwriting/corruption"). The correct solution is to change `frm.` into `frame->`, resulting in: [...] static bool frame_was_changed(const struct xdp_page_head *head) { /* xdp_scrub_frame() zeroes the data pointer, flags is the last field, * i.e. has the highest chances to be overwritten. If those two are * untouched, it's most likely safe to skip the context reset. */ return head->frame->data != head->orig_ctx.data || head->frame->flags != head->orig_ctx.flags; } [...] The main changes are: 1) Rework BPF verifier log behavior and implement it as a rotating log by default with the option to retain old-style fixed log behavior, from Andrii Nakryiko. 2) Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params, from Christian Ehrig. 3) Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton, from Alexei Starovoitov. 4) Optimize hashmap lookups when key size is multiple of 4, from Anton Protopopov. 5) Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps, from David Vernet. 6) Add support for stashing local BPF kptr into a map value via bpf_kptr_xchg(). This is useful e.g. for rbtree node creation for new cgroups, from Dave Marchevsky. 7) Fix BTF handling of is_int_ptr to skip modifiers to work around tracing issues where a program cannot be attached, from Feng Zhou. 8) Migrate a big portion of test_verifier unit tests over to test_progs -a verifier_* via inline asm to ease {read,debug}ability, from Eduard Zingerman. 9) Several updates to the instruction-set.rst documentation which is subject to future IETF standardization (https://lwn.net/Articles/926882/), from Dave Thaler. 10) Fix BPF verifier in the __reg_bound_offset's 64->32 tnum sub-register known bits information propagation, from Daniel Borkmann. 11) Add skb bitfield compaction work related to BPF with the overall goal to make more of the sk_buff bits optional, from Jakub Kicinski. 12) BPF selftest cleanups for build id extraction which stand on its own from the upcoming integration work of build id into struct file object, from Jiri Olsa. 13) Add fixes and optimizations for xsk descriptor validation and several selftest improvements for xsk sockets, from Kal Conley. 14) Add BPF links for struct_ops and enable switching implementations of BPF TCP cong-ctls under a given name by replacing backing struct_ops map, from Kui-Feng Lee. 15) Remove a misleading BPF verifier env->bypass_spec_v1 check on variable offset stack read as earlier Spectre checks cover this, from Luis Gerhorst. 16) Fix issues in copy_from_user_nofault() for BPF and other tracers to resemble copy_from_user_nmi() from safety PoV, from Florian Lehner and Alexei Starovoitov. 17) Add --json-summary option to test_progs in order for CI tooling to ease parsing of test results, from Manu Bretelle. 18) Batch of improvements and refactoring to prep for upcoming bpf_local_storage conversion to bpf_mem_cache_{alloc,free} allocator, from Martin KaFai Lau. 19) Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations, from Quentin Monnet. 20) Fix attaching fentry/fexit/fmod_ret/lsm to modules by extracting the module name from BTF of the target and searching kallsyms of the correct module, from Viktor Malik. 21) Improve BPF verifier handling of '<const> <cond> <non_const>' to better detect whether in particular jmp32 branches are taken, from Yonghong Song. 22) Allow BPF TCP cong-ctls to write app_limited of struct tcp_sock. A built-in cc or one from a kernel module is already able to write to app_limited, from Yixin Shen.
