  bpf, sockmap: Fix cork use-after-free in tcp_bpf_sendmsg() (2026-07-24 15:04:11 -0700)

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

- Fix tcp_bpf_sendmsg() error path mistaking a concurrently-freed
  sk_psock->cork for the local temporary message and freeing it
  again. (Chengfeng Ye)

- Reject passing scalar NULL to nonnull arg of a global subprog.
  Previously the verifier did not account for the cases directly
  passing scalars to a global subprog, e.g.: 'global_func(0);'
  would pass even if 'global_func' argument was marked nonnull.
  (Amery Hung)
