packets, only sent packets, or all packets be accepted, with an
implementation for Linux.
Add an implementation for BPF platforms that support BIOCSSEESENT.
rename it again to DLT_PPP_PPPD, and rename other #defines to match.
Add backwards-compatibility #defines of DLT_PPP_WITH_DIRECTION and
DLT_LINUX_PPP_WITHDIRECTION for software that used them.
to pointer variables, so the signature can't be changed).
From Gisle Vanem: assign to the right variables in the Win32
version-string construction code (where one criterion for being "right"
is that the variable exist...).
UN*Xy-enough platform that the Makefile.in rules to generate "version.h"
work), and use the stuff from "version.h" iff HAVE_VERSION_H is defined,
so we can use it even with WinPcap.
DLT_IEEE802_11_RADIO_AVS for future use with the AVS radio header.
Fix a comment.
Put in reserved LINKTYPE_USERn values corresponding to the reserved
DLT_USERn values.
devices, offer DLT_DOCSIS as one of the choices of link-layer type, and
support setting that type as meaning just "set libpcap's notion of the
link-layer type to DLT_DOCSIS" without telling the driver to use
DLT_DOCSIS.
Added support for nonblocking operation.
Added support for processing more than a single packet in
pcap_dispatch().
Fixed bug in loss counter code.
Improved portability of loss counter code (e.g. use UINT_MAX
instead of 0xffff).
Removed unused local variables.
Added required headers (ctype.h, limits.h, unistd.h,
netinet/in.h).
Changed semantics to match those of standard pcap on linux.
- packets rejected by the filter are not counted.
reading packets from a pcap_t, and make "pcap_read()" call it. That
removes the last place where we have to check for a pcap_t that refers
to a DAG card rather than a live capture, so get rid of the "is_dag" flag.
handles setting a filter for a pcap_t. Have "pcap_setfilter()" call it,
rather than being a per-platform function. The per-platform functions
don't need to check for an offline capture any more, as they're not
called for an offline capture (and the ones that just call
"install_bpf_program()" don't need to exist at all).
getting statistics for a pcap_t. Have "pcap_stats()" call it, rather
than being a per-platform function; have stats routines for non-live
pcap_t's that return an error.
the platform-dependent part of closing a pcap_t (and the
live-vs-savefile part as well, so that function must close the file
descriptor and free up any buffers allocated).
In the Digital UNIX support, add in a check for a memory allocation
failure.
and if it differs from the wpcap.dll version string, report both
versions (just in case somebody happens to have different versions of
wpcap.dll and packet.dll installed).
"pcap_next_ex()" a pointer to pointer to const u_char, to squelch
compiler warnings and to let the caller know that they're not supposed
to modify the data), and additional explanation in "pcap_next_ex()" of
the return-code conflict.
