Fedora EPEL 5 Update: libnet-1.1.5-1.el5

-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2010-3854 2010-12-29 18:14:29 -------------------------------------------------------------------------------- Name : libnet Product : Fedora EPEL 5 Version : 1.1.5 Release : 1.el5 URL : http://www.sourceforge.net/projects/libnet-dev/ Summary : C library for portable packet creation and injection Description : Libnet is an API to help with the construction and handling of network packets. It provides a portable framework for low-level network packet writing and handling (use libnet in conjunction with libpcap and you can write some really cool stuff). Libnet includes packet creation at the IP layer and at the link layer as well as a host of supplementary and complementary functionality. -------------------------------------------------------------------------------- Update Information: Upstream changes for libnet 1.1.5: - IRIX: Get MAC address from ioctl(), not by spawning shell. - Compile fix for IRIX (added includes) - Don't explicitly check for UID 0, we may have capabilities even if not root. - Cleaned up implementations of libnet_get_hwaddr(), some leaked memory, one returned a pointer to data on the stack, and the others return a pointer to static data. I'm settling on the non-reentrant static data form. - Visual C++ compiler(v9.0) uses bitfield type as a hint to pad the bitfield, so struct was too long. - Further simplify autogen.sh - Removed dependency on net/bpf.h, and on pcap.h. - LBL_ALIGN check is unused, removing. - Don't include pcap.h if we've already got net/bpf.h, pcap has it's own bpf. - Make libnet_get_hwaddr work in the last few releases of OpenBSD - Get DLT types from the source, <pcap.h>. - Use autoconf -ivf in autogen.sh - Don't distribute libnet.h, it is generated by configure - AIX build failures fixed, cause was inclusion of system headers libnet no longer uses - Add a link to the old docs. - Added links to github and sourceforge. - Replace C99/C++ comments with traditional C comments. - checksum would segfault if a IP checksum was requested for a non-ipv4 header - Closer backwards compat, assume its ipv4 if it's not ipv6. This seems totally wrong, but so it goes. - Try using the ip_len header field to guess the input buffer's size. - libnet_do_checksum(), despite being "internal", is used by external code. libnet needs to maintain backwards API compatibility, tcpsic from the isic package is an example of a binary failing when calling the new API with the old arguments. - merged icmpv6 patch in, but I believe either it or the sample/icmp6_unreach generates the cksum incorrectly - Use libtool-1 or libtool-2 whatever available - Avoid looking at /dev and /usr/include when cross-compiling Alon: The following code support cross compiling: 1. You CANNOT check for /usr/include stuff as cross compiler is installed else-where. Autoconf know how to do this, use its header detection logic and ask the result. 2. Testing for /dev/ can be done only when not cross compiling... - Corrected target_os check, it was broke for linuxgnu, and m4 syntax was invalid Alon:The following change is needed in order to solve two issues: 1. linuxgnu and such target os. 2. You cannot set variable with space before '=' as it tries to execute the variable... 3. Print result of test in case of linux - --with-link-layer broken, was using wrong macro name, and didn't include all link types - ac_cv_c_bigendian is yes, not "big" - Remove dead code. - h_len is calculated for ip, udp, tcp, icmp, and igmp, so is allowed to be zero. - libnet_t's fd should be initialized to an invalid value, or libnet_destroy() will close stdin. - Alon's use of AC_CHECK_HEADERS fails to detect headers. Reverted part of 57acd56f09158decb69f301e7547ce8cde6ac63f - With link_none, the link apis were failing with not error message. - man doc makefile wasn't correctly referring to the srcdir - Avoid mallocing zero bytes, it perturbs electric fence. - autotools patches for cross compiling and seperate builddir - html doc makefile wasn't correctly referring to the srcdir - ip_offset is now calculated on the fly, and UDP and TCP no longer use h_len - IP offset calculation should allow nesting of IP protocols. - Remove gccisms in bitfield definitions. - injection type of LIBNET_NONE, for packet construction without injection (also, more const correctness) - Notes about checksumming. - libnet_build_tcp was not returning the ptag. - Packet boundaries are now passed to _do_checksum(), so it can validate its input. Hopefully, this will end the recurring segmentation faults due to buffer overruns. - TCP building is triggering memory overwrites; closer examination shows the link list manipulation to be wrong, and the checksumming approach to be incapable of working. I reworked code to simplify and clarify how it works currently, in preparation to fixing it. - Updated comments and notes. - Null the pointer in the about-to-be-freed structure, not the one on the stack. - Added missing pblock types, and made strings consistent with definitions. - Change version policy, we will be 1.1.4 until 1.1.5 is released. - Bring CHANGELOG up to date with today, and script used to generated it. - Begin implementation and tests for repairing pblocks after an update. - libnet_pblock_insert_before() didn't remove ptag2 from old location - Clarifications in document comments. - Don't doxygen process internal header libnet-headers.h - Declared many constant arguments as const, const-correct code spews warnings when built against libnet. - Include pcap DLT_ types from correct header, was using an internal one before. - Declared many constant arguments as const, const-correct code spews warnings when built against libnet. - Note about build_data, which doesn't update ip_offset, among other problems. - libnet_clear_packet() wasn't clearing all packet context. - Why don't TCP and UDP use the DATA pblock type? - whitespace cleanup - Add libnet_dll.c as extra, so its there for win32, and build libnet_link.c - This file wasn't being built, and needed to include bpf to build. - Forgot to make device a const string here, too. - make string argument constant - only ignore Makefile in libnet/ - Replace u_intX_t with C99 uintX_t. - pclose() following popen(), not fclose() - snoof & dlpi: don't free on libnet_link_close() - Summarize changes for log. - Reindented, removing hard tabs, and using consistent brace positioning. - The non-standard types are no longer used. - /sw/.. path doesn't always exist - src/libnet_link_snoop.c: Only fclose if f!=NULL - src/libnet_link_snoop.c: fixed snoop-based backend. Works on IRIX. - Use uint64_t, not u_int64_t - define a lying gethostbyname2() if it's not defined - define STDOUT_FILENO if it's not defined - configure.in: check for gethostbyname2 - configure.in: Check for uint{16,32,64}_t - Configure switch to install samples - Attempt at applying a patch to get installable samples, which doesn't work. - Pointers not cleared after free could lead to double deallocation. - Convert CRLF to LF. - Auto* changes to work on OS X from git checkout. - Update autobuild endianness and unaligned checks. - Add srcdir to include path. - Adjust srcdir and builddir so libnet can build out-of-tree -------------------------------------------------------------------------------- This update can be installed with the "yum" update programs.
