Subject: pull-request: bpf-next 2025-06-27

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

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

We've added 6 non-merge commits during the last 8 day(s) which contain
a total of 6 files changed, 120 insertions(+), 20 deletions(-).

The main changes are:

1) Fix RCU usage in task_cls_state() for BPF programs using helpers like
   bpf_get_cgroup_classid_curr() outside of networking, from Charalampos
   Mitrodimas.

2) Fix a sockmap race between map_update and a pending workqueue from
   an earlier map_delete freeing the old psock where both pointed to the
   same psock->sk, from Jiayuan Chen.

3) Fix a data corruption issue when using bpf_msg_pop_data() in kTLS which
   failed to recalculate the ciphertext length, also from Jiayuan Chen.

4) Remove xdp_redirect_map{,_err} trace events since they are unused and
   also hide XDP trace events under CONFIG_BPF_SYSCALL, from Steven Rostedt.
