|
||||
Summary for 1.4.0 libpcap release
|
||||
Add netfilter/nfqueue interface.
|
||||
If we don't have support for IPv6 address resolution, support,
|
||||
in filter expressions, what IPv6 stuff we can.
|
||||
Checks added for malloc()/realloc()/etc. failures.
|
||||
Fix pcap-config to include -lpthread if canusb support is
|
||||
present
|
||||
Try to fix "pcap_parse not defined" problems when --without-flex
|
||||
and --without-bison are used when you have Flex and Bison
|
||||
Fix some issues with the pcap_loop man page.
|
||||
Fix pcap_getnonblock() and pcap_setnonblock() to fill in the
|
||||
supplied error message buffer
|
||||
Fix typo that, it appeared, would cause pcap-libdlpi.c not to
|
||||
compile (perhaps systems with libdlpi also have BPF and use
|
||||
that instead)
|
||||
Catch attempts to call pcap_compile() on a non-activated pcap_t
|
||||
Fix crash on Linux with CAN-USB support without usbfs
|
||||
Fix addition of VLAN tags for Linux cooked captures
|
||||
Check for both EOPNOTSUPP and EINVAL after SIOCETHTOOL ioctl, so
|
||||
that the driver can report either one if it doesn't support
|
||||
SIOCETHTOOL
|
||||
Add DLT_INFINIBAND and DLT_SCTP
|
||||
Describe "proto XXX" and "protochain XXX" in the pcap-filter man
|
||||
page
|
||||
Handle either directories, or symlinks to directories, that
|
||||
correspond to interfaces in /sys/class/net
|
||||
Fix handling of VLAN tag insertion to check, on Linux 3.x
|
||||
kernels, for VLAN tag valid flag
|
||||
Clean up some man pages
|
||||
Support libnl3 as well as libnl1 and libnl2 on Linux
|
||||
|
||||
Friday March 30, 2012. mcr@sandelman.ca
|
||||
Summary for 1.3.0 libpcap release
|
||||
Handle DLT_PFSYNC in {FreeBSD, other *BSD+Mac OS X, other}.
