 +This directory contains source code for libpcap, a system-independent
 +interface for user-level packet capture.  libpcap provides a portable
 +framework for low-level network monitoring.  Applications include
 +network statistics collection, security monitoring, network debugging,
 +etc.  Since almost every system vendor provides a different interface
 +for packet capture, and since we've developed several tools that
 +require this functionality, we've created this system-independent API
 +to ease in porting and to alleviate the need for several
 +system-dependent packet capture modules in each application.

 +
 +### Support for particular platforms and BPF
 +For some platforms there are `README.{system}` files that discuss issues
 +with the OS's interface for packet capture on those platforms, such as
 +how to enable support for that interface in the OS, if it's not built in
 +by default.
 +
 +The libpcap interface supports a filtering mechanism based on the
 +architecture in the BSD packet filter.  BPF is described in the 1993
 +Winter Usenix paper ``The BSD Packet Filter: A New Architecture for
 +User-level Packet Capture''
 +([compressed PostScript](https://www.tcpdump.org/papers/bpf-usenix93.ps.Z),
 +[gzipped PostScript](https://www.tcpdump.org/papers/bpf-usenix93.ps.gz),
 +[PDF](https://www.tcpdump.org/papers/bpf-usenix93.pdf)).
 +
 +Although most packet capture interfaces support in-kernel filtering,
 +libpcap utilizes in-kernel filtering only for the BPF interface.
 +On systems that don't have BPF, all packets are read into user-space
 +and the BPF filters are evaluated in the libpcap library, incurring
 +added overhead (especially, for selective filters).  Ideally, libpcap
 +would translate BPF filters into a filter program that is compatible
 +with the underlying kernel subsystem, but this is not yet implemented.
 +
 +BPF is standard in 4.4BSD, BSD/OS, NetBSD, FreeBSD, OpenBSD, DragonFly
 +BSD, macOS, and Solaris 11; an older, modified and undocumented version
 +is standard in AIX.  {DEC OSF/1, Digital UNIX, Tru64 UNIX} uses the
 +packetfilter interface but has been extended to accept BPF filters
 +(which libpcap utilizes).
 +
 +Linux has a number of BPF based systems, and libpcap does not support
 +any of the eBPF mechanisms as yet, although it supports many of the
 +memory mapped receive mechanisms.
 +See the [Linux-specific README](doc/README.linux) for more information.
 +
 +### Note to Linux distributions and *BSD systems that include libpcap:
 +
 +There's now a rule to make a shared library, which should work on Linux
 +and *BSD, among other platforms.
 +
 +It sets the soname of the library to `libpcap.so.1`; this is what it
 +should be, **NOT** `libpcap.so.1.x` or `libpcap.so.1.x.y` or something such as
 +that.
 +
 +We've been maintaining binary compatibility between libpcap releases for
 +quite a while; there's no reason to tie a binary linked with libpcap to
 +a particular release of libpcap.
