  bpf, test_run: Fix LIVE_FRAME frame update after a page has been recycled (2024-10-31 16:15:21 +0100)

----------------------------------------------------------------
BPF fixes:

- Fix BPF verifier to force a checkpoint when the program's jump
  history becomes too long (Eduard Zingerman)

- Add several fixes to the BPF bits iterator addressing issues
  like memory leaks and overflow problems (Hou Tao)

- Fix an out-of-bounds write in trie_get_next_key (Byeonguk Jeong)

- Fix BPF test infra's LIVE_FRAME frame update after a page has
  been recycled (Toke Høiland-Jørgensen)

- Fix BPF verifier and undo the 40-bytes extra stack space for
  bpf_fastcall patterns due to various bugs (Eduard Zingerman)

- Fix a BPF sockmap race condition which could trigger a NULL
  pointer dereference in sock_map_link_update_prog (Cong Wang)

- Fix tcp_bpf_recvmsg_parser to retrieve seq_copied from tcp_sk
  under the socket lock (Jiayuan Chen)
