Linus Torvalds 35f301dd45 Merge tag 'bpf-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf
Pull bpf fixes from Daniel Borkmann:

 - Fix a bug in the BPF verifier to track changes to packet data
   property for global functions (Eduard Zingerman)

 - Fix a theoretical BPF prog_array use-after-free in RCU handling of
   __uprobe_perf_func (Jann Horn)

 - Fix BPF tracing to have an explicit list of tracepoints and their
   arguments which need to be annotated as PTR_MAYBE_NULL (Kumar
   Kartikeya Dwivedi)

 - Fix a logic bug in the bpf_remove_insns code where a potential error
   would have been wrongly propagated (Anton Protopopov)

 - Avoid deadlock scenarios caused by nested kprobe and fentry BPF
   programs (Priya Bala Govindasamy)

 - Fix a bug in BPF verifier which was missing a size check for
   BTF-based context access (Kumar Kartikeya Dwivedi)

 - Fix a crash found by syzbot through an invalid BPF prog_array access
   in perf_event_detach_bpf_prog (Jiri Olsa)

 - Fix several BPF sockmap bugs including a race causing a refcount
   imbalance upon element replace (Michal Luczaj)

 - Fix a use-after-free from mismatching BPF program/attachment RCU
   flavors (Jann Horn)
