Clean up some comments.
Protect all references to the USB stuff from the common Linux code with
PCAP_SUPPORT_USB, just as references to the Bluetooth code are protected
with PCAP_SUPPORT_BT.
source directory and the target include directory, and have include
files at the top-level directory to include those headers, for backwards
compatibility.
Update the FILES and INSTALL.txt files to reflect current reality.
packets that didn't arrive on that interface, so packets from other
interfaces that get onto the socket queue before we bind the socket to
the interface don't get supplied to the application (binding the socket
doesn't discard incoming packets).
"getsockopt()" argument, return those statistics, rather than falling
through and returning the statistics the way we would if
PACKET_STATISTICS weren't supported.
packets, only sent packets, or all packets be accepted, with an
implementation for Linux.
Add an implementation for BPF platforms that support BIOCSSEESENT.
at least on 2.2 and later kernels; the socket is bound (except for
sending on the "any" device, which we don't support), so a destination
address isn't necessary.
Generate the right error string for attempts to send on the "any"
device, and also disallow sends if we're in cooked mode.
In the Linux kernel the packet statistics are zeroed during each retrieval.
In contrast, on FreeBSD, the packet statistics are retrived using
ioctl(BIOCGSTATS):
The patch adds a static variable to pcap_stats_linux() which
holds a running total of the packet statistics so that the behaviour
of pcap_stats() on Linux matches the behaviour of FreeBSD.
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.
support Linux Frame Relay ARPHRD_FRAD as Frame Relay with an FR
header;
support Linux Frame Relay ARPHRD_DLCI in cooked mode;
current Linux kernels use the name ARPHRD_CISCO for Cisco HDLC
(513).
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.
with some interfaces (see bug 599857 in the SourceForge list of libpcap
bugs), and, even if it doesn't cause problems, it's different from
what's done on other platforms.
which supplies different headers from BSD ARCNET, and fixes to the
ARCNET code generator (the protocol ID field is 1 byte, so the values
for it shouldn't be byte-swapped).
Whitespace cleanups.
The "NetBSD-style" ARCNET headers are used in other BSDs as well, so
just call them "BSD-style".
argument to "pcap_open_live()" a "const" pointer.
Constify some additional device name arguments, and update the man page
to reflect some arguments that were already consts.
Young <dyoung@ojctech.com>, with some minor changes by Jason R. Thorpe
<thorpej@netbsd.org>, and further changes by me to support it on BPF
systems lacking BIOCGDLTLIST and other platforms lacking an equivalent
feature.
Update Jason Thorpe's e-mail address (Zembu is going away, if it hasn't
done so already).
Add APIs to map DLT names to DLT values and vice versa.
new 2.2-or-later kernel, with PF_PACKET sockets including SOL_PACKET,
but with an older version of the C library whose headers don't define
SOL_PACKET.
On those systems, define SOL_PACKET to have the value it has in the
2.2.0 kernel; this means we can get rid of the "#ifdef
SOL_PACKET"/#endif stuff wrapped around the code to turn promiscuous
mode on or off (we don't want that #ifdeffed out, as if it's absent we
won't pay attention to the "promiscuous mode" flag argument to
"pcap_open_live()").
