Subject: pull-request: bpf-next 2023-01-28
Hi David, hi Jakub, hi Paolo, hi Eric,
The following pull-request contains BPF updates for your *net-next* tree.
We've added 124 non-merge commits during the last 22 day(s) which contain
a total of 124 files changed, 6386 insertions(+), 1827 deletions(-).
There is a merge conflict in kernel/bpf/offload.c between the commit
ef01f4e25c17 ("bpf: restore the ebpf program ID for BPF_AUDIT_UNLOAD and
PERF_BPF_EVENT_PROG_UNLOAD") from net-next tree and the commit 89bbc53a4dbb
("bpf: Reshuffle some parts of bpf/offload.c") from bpf-next tree. Easiest
is to follow Stephen's diff removing the bpf_prog_free_id() from offload:
https://lore.kernel.org/bpf/20230124094403.76e0011f@canb.auug.org.au
The main changes are:
1) Implement XDP hints via kfuncs with initial support for RX hash and timestamp
metadata kfuncs, from Stanislav Fomichev and Toke Høiland-Jørgensen.
Measurements on overhead: https://lore.kernel.org/bpf/875yellcx6.fsf@toke.dk
2) Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes
and syscall as a special case, from Andrii Nakryiko.
3) Significantly reduce the search time for module symbols by livepatch and BPF,
from Jiri Olsa and Zhen Lei.
4) Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking
which tasks end up running on which CPUs in different time intervals, from David Vernet.
5) Fix several issues in the dynptr processing such as stack slot liveness propagation,
missing checks for PTR_TO_STACK variable offset, etc, from Kumar Kartikeya Dwivedi.
6) Various performance improvements, fixes, and introduction of more than just one
XDP program to XSK selftests, from Magnus Karlsson.
7) Big batch to BPF samples to reduce deprecated functionality, from Daniel T. Lee.
8) Enable struct_ops programs to be sleepable in verifier, from David Vernet.
9) Reduce pr_warn() noise on BTF mismatches when they are expected under the
CONFIG_MODULE_ALLOW_BTF_MISMATCH config anyway, from Connor O'Brien.
10) Describe modulo and division by zero behavior of the BPF runtime in BPF's
instruction specification document, from Dave Thaler.
11) Several improvements to libbpf API documentation in libbpf.h, from Grant Seltzer.
12) Improve resolve_btfids header dependencies related to subcmd and add proper
support for HOSTCC, from Ian Rogers.
13) Add ipip6 and ip6ip decapsulation support for bpf_skb_adjust_room() helper
along with BPF selftests, from Ziyang Xuan.
14) Simplify the parsing logic of structure parameters for BPF trampoline in the
x86-64 JIT compiler, from Pu Lehui.
15) Get BTF working for kernels with CONFIG_RUST enabled by excluding Rust compilation
units with pahole, from Martin Rodriguez Reboredo.
16) Get bpf_setsockopt() working for kTLS on top of TCP sockets, from Kui-Feng Lee.
17) Disable stack protection for BPF objects in bpftool given BPF backends don't
support it, from Holger Hoffstätte.
