Hi David, hi Jakub, hi Paolo, hi Eric,

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

We've added 15 non-merge commits during the last 7 day(s) which contain
a total of 18 files changed, 583 insertions(+), 55 deletions(-).

The main changes are:

1) Fix broken BPF multi-uprobe PID filtering logic which filtered by thread while
   the promise was to filter by process, from Andrii Nakryiko.

2) Fix the recent influx of syzkaller reports to sockmap which triggered a
   locking rule violation by performing a map_delete, from Jakub Sitnicki.

3) Fixes to netkit driver in particular on skb->pkt_type override upon pass
   verdict, from Daniel Borkmann.

4) Fix an integer overflow in resolve_btfids which can wrongly trigger build
   failures, from Friedrich Vock.

5) Follow-up fixes for ARC JIT reported by static analyzers, from Shahab Vahedi.
