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.
