Do not check IPv6 bit in cqe status if CONFIG_IPV6 is not enabled. Function check_csum() is reached only with IPv4 or IPv6 set (if enabled), if IPv6 is not set (or is not enabled) it is redundant to test the IPv4 bit.

Daniel Borkmann says: ==================== pull-request: bpf-next 2017-12-28 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Fix incorrect state pruning related to recognition of zero initialized stack slots, where stacksafe exploration would mistakenly return a positive pruning verdict too early ignoring other slots, from Gianluca. 2) Various BPF to BPF calls related follow-up fixes. Fix an off-by-one in maximum call depth check, and rework maximum stack depth tracking logic to fix a bypass of the total stack size check reported by Jann. Also fix a bug in arm64 JIT where prog->jited_len was uninitialized. Addition of various test cases to BPF selftests, from Alexei. 3) Addition of a BPF selftest to test_verifier that is related to BPF to BPF calls which demonstrates a late caller stack size increase and thus out of bounds access. Fixed above in 2). Test case from Jann. 4) Addition of correlating BPF helper calls, BPF to BPF calls as well as BPF maps to bpftool xlated dump in order to allow for better BPF program introspection and debugging, from Daniel. 5) Fixing several bugs in BPF to BPF calls kallsyms handling in order to get it actually to work for subprogs, from Daniel. 6) Extending sparc64 JIT support for BPF to BPF calls and fix a couple of build errors for libbpf on sparc64, from David. 7) Allow narrower context access for BPF dev cgroup typed programs in order to adapt to LLVM code generation. Also adjust memlock rlimit in the test_dev_cgroup BPF selftest, from Yonghong. 8) Add netdevsim Kconfig entry to BPF selftests since test_offload.py relies on netdevsim device being available, from Jakub. 9) Reduce scope of xdp_do_generic_redirect_map() to being static, from Xiongwei. 10) Minor cleanups and spelling fixes in BPF verifier, from Colin. ==================== Signed-off-by: NDavid S.

Willem de Bruijn says: ==================== zerocopy refinements 1/4 is a small optimization follow-up to the earlier fix to skb_segment: check skb state once per skb, instead of once per frag. 2/4 makes behavior more consistent between standard and zerocopy send: set the PSH bit when hitting MAX_SKB_FRAGS. This helps GRO. 3/4 resolves a surprising inconsistency in notification: because small packets were not stored in frags, they would not set the copied error code over loopback. This change also optimizes the path by removing copying and making tso_fragment cheaper. 4/4 follows-up to 3/4 by no longer allocated now unused memory. this was actually already in RFC patches, but dropped as I pared down the patch set during revisions. ==================== Signed-off-by: NDavid S.

This avoids an unnecessary copy of 1-2KB and improves tso_fragment, which has to fall back to tcp_fragment if skb->len != skb_data_len. It also avoids a surprising inconsistency in notifications: Zerocopy packets sent over loopback have their frags copied, so set SO_EE_CODE_ZEROCOPY_COPIED in the notification. But this currently does not happen for small packets, because when all data fits in the linear fragment, data is not copied in skb_orphan_frags_rx.

This is a net-next follow-up to commit 268b7906 ("skbuff: orphan frags before zerocopy clone"), which fixed a bug in net, but added a call to skb_zerocopy_clone at each frag to do so. When segmenting skbs with user frags, either the user frags must be replaced with private copies and uarg released, or the uarg must have its refcount increased for each new skb. skb_orphan_frags does the first, except for cases that can handle reference counting. skb_zerocopy_clone then does the second. Call these once per nskb, instead of once per frag. That is, in the common case. With a frag list, also refresh when the origin skb (frag_skb) changes.
