Merge tag 'bpf-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf

Pull BPF fixes from Daniel Borkmann:

 - Initialize task local storage before fork bails out to free the task
   (Jann Horn)

 - Fix insn_aux_data leak on verifier error path (KaFai Wan)

 - Reject BPF inode storage map creation when BPF LSM is uninitialized
   (Matt Bobrowski)

 - Mask pseudo pointer values in verifier logs when pointer leaks are
   not allowed (Nuoqi Gui)

 - Harden BPF JIT against spraying via IBPB flush (Pawan Gupta)

 - Reject a skb-modifying SK_SKB stream parser since the latter is only
   meant to measure the next message (Sechang Lim)

 - Fix bpf_refcount_acquire to reject refcounted allocation arguments
   with a non-zero fixed offset (Yiyang Chen)
