[PATCH net-next v17 00/25] Introducing OpenVPN Data Channel Offload

by Antonio Quartulli

Notable changes since v16: * fixed usage of netdev tracker by removing dev_tracker member from ovpn_priv and adding it to ovpn_peer and ovpn_socket as those are the objects really holding a ref to the netdev * switched ovpn_get_dev_from_attrs() to GFP_ATOMIC to prevent sleep under rcu_read_lock * allocated netdevice_tracker in ovpn_nl_pre_doit() [stored in user_ptr[1]] to keep track of the netdev reference held during netlink handler calls * moved whole socket detaching routine to worker. This way the code is allowed to sleep and in turn it can be executed under lock_sock. This lock allows us to happily coordinate concurrent attach/detach calls. (note: lock is acquired everytime the refcnt for the socket is decremented, because this guarantees us that setting the refcnt to 0 and detaching the socket will happen atomically) * dropped kref_put_sock()/refcount handler as it's not required anymore, thanks to the point above * re-arranged ovpn_socket_new() in order to simplify error path by first allocating the new ovpn_sock and then attaching Please note that some patches were already reviewed/tested by a few people. iThese patches have retained the tags as they have hardly been touched.

[PATCH bpf-next v2 0/3] selftests: bpf: Migrate test_xdp_redirect.sh to test_progs

by Bastien Curutchet (eBPF Foundation)

Hi all, This patch series continues the work to migrate the *.sh tests into prog_tests. test_xdp_redirect.sh tests the XDP redirections done through bpf_redirect(). These XDP redirections are already tested by prog_tests/xdp_do_redirect.c but IMO it doesn't cover the exact same code path because xdp_do_redirect.c uses bpf_prog_test_run_opts() to trigger redirections of 'fake packets' while test_xdp_redirect.sh redirects packets coming from the network. Also, the test_xdp_redirect.sh script tests the redirections with both SKB and DRV modes while xdp_do_redirect.c only tests the DRV mode. The patch series adds two new test cases in prog_tests/xdp_do_redirect.c to replace the test_xdp_redirect.sh script.

[PATCH bpf-next] bpf: veristat: Document verifier log dumping capability

by Daniel Xu

`-l2 -v` is a useful combination of flags to dump the entire verification log. This is helpful when making changes to the verifier, as you can see what it thinks program one instruction at a time. This was more or less a hidden feature before. Document it so others can discover it.
