[Daniel Borkmann <daniel@iogearbox.net>]

Hi David,

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix in the BPF verifier to reject modified ctx pointers on helper
   functions, from Daniel.

2) Fix in BPF kselftests for get_cgroup_id_user() helper to only
   record the cgroup id for a provided pid in order to reduce test
   failures from processes interferring with the test, from Yonghong.

3) Fix a crash in AF_XDP's mem accounting when the process owning
   the sock has CAP_IPC_LOCK capabilities set, from Daniel.

4) Fix an issue for AF_XDP on 32 bit machines where XDP_UMEM_PGOFF_*_RING
   defines need ULL suffixes and use loff_t type as they are otherwise
   truncated, from Geert.
