pcap-linux.c memory-mapped mode.
Always doing a poll() if there are no packets available allows us to
catch disappearing interfaces in memory-mapped mode, so remove the
caveats about Linux.
- Fixed bug where create_ring would fail for particular snaplen and
buffer size combinations
- Changed ring allocation to retry with 5% less buffer size instead of
50%
structure we got back from getaddrinfo().
Plug some other getaddrinfo() leaks while we're at it.
Fail if you try to use "gateway" on ATM if we're not checking for ATM
LANE.
e-mail address while we're at it.
Use <fcntl.h> rather than <sys/file.h> in pcap-bpf.c - that's the right
header for open().
Don't include <sys/timeb.h> - it doesn't define anything that pcap-bpf.c
should need.
Update CREDITS to give Jon Smirl credit for some of the USB fixes.
Rename DLT_USB_LINUX_MMAP to DLT_USB_LINUX_MMAPPED, and declare a
structure for the header of packets in DLT_USB_LINUX_MMAPPED captures.
put the transfer direction in the uppermost bit of the endpoint
number, rather than the uppermost bit of the transfer type, when
reading in text mode, just as is the case in binary mode;
check the URB data length against 0 when deciding whether
there's no URB tag.
the tcpdump manual page, so that documentation for other applications
using libpcap can refer to it.
Update pcap(3) to refer to it - and not to suggest sending patches to
patches@tcpdump.org, which is a spam magnet that's no longer read by
anybody.
if it does, use that for the pf definitions;
if it doesn't, don't compile in pf support;
as both OpenBSD and FreeBSD have changed the pf definitions and header
format without changing the DLT value, so you can't reliably read
pflog-format libpcap files on a machine running an OS version other than
the one on which the file was generated.
types. Modified to add ieee80211.h from FreeBSD, rather than depending
on the OS supplying the header, and to support all 802.11 radio header
types.
Clean up some link-layer type checks and the messages for failing those
checks.
Linux. The USB sniffing code for Linux now supplies a per-packet header
based on the one supplied by the Linux binary sniffing interface, so we
add a new DLT_ value and use that.
Fix his e-mail address, and add him to the credits.
when building a shared library, build with "-fPIC" on Linux, to
support x86_64;
link with "$(CC) -shared" rather than "ld -shared" when building
a ".so" shared library (as would be done with ELF systems that
use GCC);
add an explicit "-ldag" when building the shared library, so the
DAG library dependency is explicit.
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).
