userspace programs that use eBPF instruction macros need to include two files: uapi/linux/filter.h and uapi/linux/bpf.h Move common macro definitions that are shared between classic BPF and eBPF into uapi/linux/bpf_common.h, so that user app can include only one bpf.h file Cc: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

2014-10-14tcp: fix tcp_ack() performance problemEric Dumazet
We worked hard to improve tcp_ack() performance, by not accessing skb_shinfo() in fast path (cd7d8498c9a5 tcp: change tcp_skb_pcount() location) We still have one spurious access because of ACK timestamping, added in commit e1c8a607b281 ("net-timestamp: ACK timestamp for bytestreams") By checking if sk_tsflags has SOF_TIMESTAMPING_TX_ACK set, we can avoid two cache line misses for the common case. While we are at it, add two prefetchw() : One in tcp_ack() to bring skb at the head of write queue. One in tcp_clean_rtx_queue() loop to bring following skb, as we will delete skb from the write queue and dirty skb->next->prev. Add a couple of [un]likely() clauses. After this patch, tcp_ack() is no longer the most consuming function in tcp stack.

2014-10-14x86: bpf_jit: fix two bugs in eBPF JIT compilerAlexei Starovoitov
1. JIT compiler using multi-pass approach to converge to final image size, since x86 instructions are variable length. It starts with large gaps between instructions (so some jumps may use imm32 instead of imm8) and iterates until total program size is the same as in previous pass. This algorithm works only if program size is strictly decreasing. Programs that use LD_ABS insn need additional code in prologue, but it was not emitted during 1st pass, so there was a chance that 2nd pass would adjust imm32->imm8 jump offsets to the same number of bytes as increase in prologue, which may cause algorithm to erroneously decide that size converged. Fix it by always emitting largest prologue in the first pass which is detected by oldproglen==0 check. Also change error check condition 'proglen != oldproglen' to fail gracefully. 2. while staring at the code realized that 64-byte buffer may not be enough when 1st insn is large, so increase it to 128 to avoid buffer overflow (theoretical maximum size of prologue+div is 109) and add runtime check.
