+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.
