      ====================
      pull-request: bpf-next 2023-03-06
      
      We've added 85 non-merge commits during the last 13 day(s) which contain
      a total of 131 files changed, 7102 insertions(+), 1792 deletions(-).
      
      The main changes are:
      
      1) Add skb and XDP typed dynptrs which allow BPF programs for more
         ergonomic and less brittle iteration through data and variable-sized
         accesses, from Joanne Koong.
      
      2) Bigger batch of BPF verifier improvements to prepare for upcoming BPF
         open-coded iterators allowing for less restrictive looping capabilities,
         from Andrii Nakryiko.
      
      3) Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
         programs to NULL-check before passing such pointers into kfunc,
         from Alexei Starovoitov.
      
      4) Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
         local storage maps, from Kumar Kartikeya Dwivedi.
      
      5) Add BPF verifier support for ST instructions in convert_ctx_access()
         which will help new -mcpu=v4 clang flag to start emitting them,
         from Eduard Zingerman.
      
      6) Make uprobe attachment Android APK aware by supporting attachment
         to functions inside ELF objects contained in APKs via function names,
         from Daniel Müller.
      
      7) Add a new flag BPF_F_TIMER_ABS flag for bpf_timer_start() helper
         to start the timer with absolute expiration value instead of relative
         one, from Tero Kristo.
      
      8) Add a new kfunc bpf_cgroup_from_id() to look up cgroups via id,
         from Tejun Heo.
      
      9) Extend libbpf to support users manually attaching kprobes/uprobes
         in the legacy/perf/link mode, from Menglong Dong.
      
      10) Implement workarounds in the mips BPF JIT for DADDI/R4000,
         from Jiaxun Yang.
      
      11) Enable mixing bpf2bpf and tailcalls for the loongarch BPF JIT,
          from Hengqi Chen.
      
      12) Extend BPF instruction set doc with describing the encoding of BPF
          instructions in terms of how bytes are stored under big/little endian,
          from Jose E. Marchesi.
      
      13) Follow-up to enable kfunc support for riscv BPF JIT, from Pu Lehui.
      
      14) Fix bpf_xdp_query() backwards compatibility on old kernels,
          from Yonghong Song.
      
      15) Fix BPF selftest cross compilation with CLANG_CROSS_FLAGS,
          from Florent Revest.
      
      16) Improve bpf_cpumask_ma to only allocate one bpf_mem_cache,
          from Hou Tao.
      
      17) Fix BPF verifier's check_subprogs to not unnecessarily mark
          a subprogram with has_tail_call, from Ilya Leoshkevich.
      
      18) Fix arm syscall regs spec in libbpf's bpf_tracing.h, from Puranjay Mohan.
