Update libpcap to 1.1.1.
Changes:
Thu. April 1, 2010. guy@alum.mit.edu.
Summary for 1.1.1 libpcap release
Update CHANGES to reflect more of the changes in 1.1.0.
Fix build on RHEL5.
Fix shared library build on AIX.
Thu. March 11, 2010. ken@netfunctional.ca/guy@alum.mit.edu.
Summary for 1.1.0 libpcap release
Add SocketCAN capture support
Add Myricom SNF API support
Update Endace DAG and ERF support
Add support for shared libraries on Solaris, HP-UX, and AIX
Build, install, and un-install shared libraries by default;
don't build/install shared libraries on platforms we don't support
Fix building from a directory other than the source directory
Fix compiler warnings and builds on some platforms
Update config.guess and config.sub
Support monitor mode on mac80211 devices on Linux
Fix USB memory-mapped capturing on Linux; it requires a new DLT_
value
On Linux, scan /sys/class/net for devices if we have it; scan
it, or /proc/net/dev if we don't have /sys/class/net, even if
we have getifaddrs(), as it'll find interfaces with no
addresses
Add limited support for reading pcap-ng files
Fix BPF driver-loading error handling on AIX
Support getting the full-length interface description on FreeBSD
In the lexical analyzer, free up any addrinfo structure we got back
from getaddrinfo().
Add support for BPF and libdlpi in OpenSolaris (and SXCE)
Hyphenate "link-layer" everywhere
Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
In pcap_read_linux_mmap(), if there are no frames available, call
poll() even if we're in non-blocking mode, so we pick up
errors, and check for the errors in question.
Note that poll() works on BPF devices is Snow Leopard
If an ENXIO or ENETDOWN is received, it may mean the device has
gone away. Deal with it.
For BPF, raise the default capture buffer size to from 32k to 512k
Support ps_ifdrop on Linux
Added a bunch of #ifdef directives to make wpcap.dll (WinPcap) compile
under cygwin.
Changes to Linux mmapped captures.
Fix bug where create_ring would fail for particular snaplen and
buffer size combinations
Update pcap-config so that it handles libpcap requiring
additional libraries
Add workaround for threadsafeness on Windows
Add missing mapping for DLT_ENC <-> LINKTYPE_ENC
DLT: Add DLT_CAN_SOCKETCAN
DLT: Add Solaris ipnet
Don't check for DLT_IPNET if it's not defined
Add link-layer types for Fibre Channel FC-2
Add link-layer types for Wireless HART
Add link-layer types for AOS
Add link-layer types for DECT
Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
Install headers unconditionally, and include vlan.h/bluetooth.h if
enabled
Autoconf fixes+cleanup
Support enabling/disabling bluetooth (--{en,dis}able-bluetooth)
Support disabling SITA support (--without-sita)
Return -1 on failure to create packet ring (if supported but
creation failed)
Fix handling of 'any' device, so that it can be opened, and no longer
attempt to open it in Monitor mode
Add support for snapshot length for USB Memory-Mapped Interface
Fix configure and build on recent Linux kernels
Fix memory-mapped Linux capture to support pcap_next() and
pcap_next_ex()
Fixes for Linux USB capture
DLT: Add DLT_LINUX_EVDEV
DLT: Add DLT_GSMTAP_UM
DLT: Add DLT_GSMTAP_ABIS

Update libpcap to 1.1.1.
Changes:
Thu. April 1, 2010. guy@alum.mit.edu.
Summary for 1.1.1 libpcap release
Update CHANGES to reflect more of the changes in 1.1.0.
Fix build on RHEL5.
Fix shared library build on AIX.
Thu. March 11, 2010. ken@netfunctional.ca/guy@alum.mit.edu.
Summary for 1.1.0 libpcap release
Add SocketCAN capture support
Add Myricom SNF API support
Update Endace DAG and ERF support
Add support for shared libraries on Solaris, HP-UX, and AIX
Build, install, and un-install shared libraries by default;
don't build/install shared libraries on platforms we don't support
Fix building from a directory other than the source directory
Fix compiler warnings and builds on some platforms
Update config.guess and config.sub
Support monitor mode on mac80211 devices on Linux
Fix USB memory-mapped capturing on Linux; it requires a new DLT_
value
On Linux, scan /sys/class/net for devices if we have it; scan
it, or /proc/net/dev if we don't have /sys/class/net, even if
we have getifaddrs(), as it'll find interfaces with no
addresses
Add limited support for reading pcap-ng files
Fix BPF driver-loading error handling on AIX
Support getting the full-length interface description on FreeBSD
In the lexical analyzer, free up any addrinfo structure we got back
from getaddrinfo().
Add support for BPF and libdlpi in OpenSolaris (and SXCE)
Hyphenate "link-layer" everywhere
Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
In pcap_read_linux_mmap(), if there are no frames available, call
poll() even if we're in non-blocking mode, so we pick up
errors, and check for the errors in question.
Note that poll() works on BPF devices is Snow Leopard
If an ENXIO or ENETDOWN is received, it may mean the device has
gone away. Deal with it.
For BPF, raise the default capture buffer size to from 32k to 512k
Support ps_ifdrop on Linux
Added a bunch of #ifdef directives to make wpcap.dll (WinPcap) compile
under cygwin.
Changes to Linux mmapped captures.
Fix bug where create_ring would fail for particular snaplen and
buffer size combinations
Update pcap-config so that it handles libpcap requiring
additional libraries
Add workaround for threadsafeness on Windows
Add missing mapping for DLT_ENC <-> LINKTYPE_ENC
DLT: Add DLT_CAN_SOCKETCAN
DLT: Add Solaris ipnet
Don't check for DLT_IPNET if it's not defined
Add link-layer types for Fibre Channel FC-2
Add link-layer types for Wireless HART
Add link-layer types for AOS
Add link-layer types for DECT
Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
Install headers unconditionally, and include vlan.h/bluetooth.h if
enabled
Autoconf fixes+cleanup
Support enabling/disabling bluetooth (--{en,dis}able-bluetooth)
Support disabling SITA support (--without-sita)
Return -1 on failure to create packet ring (if supported but
creation failed)
Fix handling of 'any' device, so that it can be opened, and no longer
attempt to open it in Monitor mode
Add support for snapshot length for USB Memory-Mapped Interface
Fix configure and build on recent Linux kernels
Fix memory-mapped Linux capture to support pcap_next() and
pcap_next_ex()
Fixes for Linux USB capture
DLT: Add DLT_LINUX_EVDEV
DLT: Add DLT_GSMTAP_UM
DLT: Add DLT_GSMTAP_ABIS
