* MFV r276759: libpcap 1.6.2.Xin LI2015-01-06173-10257/+11302

* | Add netmap support to libpcap. Tcpdump and other native pcap application can nowLuigi Rizzo2014-10-062-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | run directly on netmap ports using netmap:foo or valeXX:YY device names. Modifications to existing code are small and trivial, the netmap-specific code is all in a new file. Please be aware that in netmap mode the physical interface is disconnected from the host stack, so libpcap will steal the traffic not just make a copy. For the full version of the code (including linux and autotools support) see https://code.google.com/p/netmap-libpcap/ MFC after: 3 days Notes: svn path=/head/; revision=272659
* | Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED.Kevin Lo2014-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The origin of WEP comes from IEEE Std 802.11-1997 where it defines whether the frame body of MAC frame has been encrypted using WEP algorithm or not. IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates whether the frame is protected by a cryptographic encapsulation algorithm.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | different version has been committed upstream in the libpcap vendor branch. This will allow people to experiment with zero-copy bpf(4) without requiring external patches. Note to enable this functionality: sysctl net.bpf.zerocopy_enable=1 By default, libpcap will use the legacy buffering method unless this sysctl variable is set to 1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - BIOCGDIRECTION and BIOCSDIRECTION get or set the setting determining whether incoming, outgoing, or all packets on the interface should be returned by BPF. Set to BPF_D_IN to see only incoming packets on the interface. Set to BPF_D_INOUT to see packets originating locally and remotely on the interface. Set to BPF_D_OUT to see only outgoing packets on the interface. This setting is initialized to BPF_D_INOUT by default. BIOCGSEESENT and BIOCSSEESENT are obsoleted by these but kept for backward compatibility. - BIOCFEEDBACK sets packet feedback mode. This allows injected packets to be fed back as input to the interface when output via the interface is successful. When BPF_D_INOUT direction is set, injected outgoing packet is not returned by BPF to avoid duplication. This flag is initialized to zero by default. Note that libpcap has been modified to support BPF_D_OUT direction for pcap_setdirection(3) and PCAP_D_OUT direction is functional now. Reviewed by: rwatson Notes: svn path=/head/; revision=167035
