[PATCH v2 0/5] binder: extended error and logging enhancements

by Carlos Llamas

This is a followup from [1], in which a split of commits was suggested by Greg. Additionally, the following changes were removed and not included in this v2 version: - dropped the binder_transaction_log_entry->strerr[] logic - dropped the binder_transaction_error() do-it-all function - dropped the re-work of current binder_user_error() messages [1] https://lore.kernel.org/r/20220421042040.759068-1-cmllamas@google.com/ Carlos Llamas (5): binder: add failed transaction logging info binder: add BINDER_GET_EXTENDED_ERROR ioctl binderfs: add extended_error feature entry binder: convert logging macros into functions binder: additional transaction error logs drivers/android/binder.c | 153 ++++++++++++++++-- drivers/android/binder_internal.h | 3 + drivers/android/binderfs.c | 8 + include/uapi/linux/android/binder.h | 16 ++ .../filesystems/binderfs/binderfs_test.c | 1 + 5 files changed, 165 insertions(+), 16 deletions(-) base-commit: 8013d1d3d2e33236dee13a133fba49ad55045e79 -- 2.36.0.464.gb9c8b46e94-goog

[PATCH v6 1/2] net: fix wrong network header length

by Lina Wang

When clatd starts with ebpf offloaing, and NETIF_F_GRO_FRAGLIST is enable, several skbs are gathered in skb_shinfo(skb)->frag_list. The first skb's ipv6 header will be changed to ipv4 after bpf_skb_proto_6_to_4, network_header\transport_header\mac_header have been updated as ipv4 acts, but other skbs in frag_list didnot update anything, just ipv6 packets. udp_queue_rcv_skb will call skb_segment_list to traverse other skbs in frag_list and make sure right udp payload is delivered to user space. Unfortunately, other skbs in frag_list who are still ipv6 packets are updated like the first skb and will have wrong transport header length. e.g.before bpf_skb_proto_6_to_4,the first skb and other skbs in frag_list has the same network_header(24)& transport_header(64), after bpf_skb_proto_6_to_4, ipv6 protocol has been changed to ipv4, the first skb's network_header is 44,transport_header is 64, other skbs in frag_list didnot change.After skb_segment_list, the other skbs in frag_list has different network_header(24) and transport_header(44), so there will be 20 bytes different from original,that is difference between ipv6 header and ipv4 header. Just change transport_header to be the same with original. Actually, there are two solutions to fix it, one is traversing all skbs and changing every skb header in bpf_skb_proto_6_to_4, the other is modifying frag_list skb's header in skb_segment_list. Considering efficiency, adopt the second one--- when the first skb and other skbs in frag_list has different network_header length, restore them to make sure right udp payload is delivered to user space.

[PATCH] selftests: clarify common error when running gup_test

by Joel Savitz

The gup_test binary will fail showing only the output of perror("open") in the case that /sys/kernel/debug/gup_test is not found. This will almost always be due to CONFIG_GUP_TEST not being set, which enables compilation of a kernel that provides this file. Add a short error message to clarify this failure and point the user to the solution.

[PATCH] kunit: take `kunit_assert` as `const`

by Miguel Ojeda

The `kunit_do_failed_assertion` function passes its `struct kunit_assert` argument to `kunit_fail`. This one, in turn, calls its `format` field passing the assert again as a `const` pointer. Therefore, the whole chain may be made `const`.
