Hi David, hi Jakub, hi Paolo, hi Eric, The following pull-request contains BPF updates for your *net* tree. We've added 8 non-merge commits during the last 6 day(s) which contain a total of 9 files changed, 34 insertions(+), 35 deletions(-). The main changes are: 1) Fix a potential use-after-free in bpf_link_free when the link uses dealloc_deferred to free the link object but later still tests for presence of link->ops->dealloc, from Cong Wang. 2) Fix BPF test infra to set the run context for rawtp test_run callback where syzbot reported a crash, from Jiri Olsa. 3) Fix bpf_session_cookie BTF_ID in the special_kfunc_set list to exclude it for the case of !CONFIG_FPROBE, also from Jiri Olsa. 4) Fix a Coverity static analysis report to not close() a link_fd of -1 in the multi-uprobe feature detector, from Andrii Nakryiko. 5) Revert support for redirect to any xsk socket bound to the same umem as it can result in corrupted ring state which can lead to a crash when flushing rings. A different approach will be pursued for bpf-next to address it safely, from Magnus Karlsson. 6) Fix inet_csk_accept prototype in test_sk_storage_tracing.c which caused BPF CI failure after the last tree fast forwarding, from Andrii Nakryiko. 7) Fix a coccicheck warning in BPF devmap that iterator variable cannot be NULL, from Thorsten Blum.
