Merge tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Alexei Starovoitov says: ==================== pull-request: bpf-next 2022-12-11 We've added 74 non-merge commits during the last 11 day(s) which contain a total of 88 files changed, 3362 insertions(+), 789 deletions(-). The main changes are: 1) Decouple prune and jump points handling in the verifier, from Andrii. 2) Do not rely on ALLOW_ERROR_INJECTION for fmod_ret, from Benjamin. Merged from hid tree. 3) Do not zero-extend kfunc return values. Necessary fix for 32-bit archs, from Björn. 4) Don't use rcu_users to refcount in task kfuncs, from David. 5) Three reg_state->id fixes in the verifier, from Eduard. 6) Optimize bpf_mem_alloc by reusing elements from free_by_rcu, from Hou. 7) Refactor dynptr handling in the verifier, from Kumar. 8) Remove the "/sys" mount and umount dance in {open,close}_netns in bpf selftests, from Martin. 9) Enable sleepable support for cgrp local storage, from Yonghong. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (74 commits) selftests/bpf: test case for relaxed prunning of active_lock.id selftests/bpf: Add pruning test case for bpf_spin_lock bpf: use check_ids() for active_lock comparison selftests/bpf: verify states_equal() maintains idmap across all frames bpf: states_equal() must build idmap for all function frames selftests/bpf: test cases for regsafe() bug skipping check_id() bpf: regsafe() must not skip check_ids() docs/bpf: Add documentation for BPF_MAP_TYPE_SK_STORAGE selftests/bpf: Add test for dynptr reinit in user_ringbuf callback bpf: Use memmove for bpf_dynptr_{read,write} bpf: Move PTR_TO_STACK alignment check to process_dynptr_func bpf: Rework check_func_arg_reg_off bpf: Rework process_dynptr_func bpf: Propagate errors from process_* checks in check_func_arg bpf: Refactor ARG_PTR_TO_DYNPTR checks into process_dynptr_func bpf: Skip rcu_barrier() if rcu_trace_implies_rcu_gp() is true bpf: Reuse freed element in free_by_rcu during allocation selftests/bpf: Bring test_offload.py back to life bpf: Fix comment error in fixup_kfunc_call function bpf: Do not zero-extend kfunc return values ... ==================== Link: https://lore.kernel.org/r/20221212024701.73809-1-alexei.starovoitov@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
