PATCH from Joe Gio : - track if AC power is connected/disconnected 0.5.5 --------------------------------------------------------------------- BUGFIX from Andreas Jacobs : - calculate correct sleeptime BUGFIX from Dario Borriello : - do not update LQ if not configured BUGFIX from Jo-Philipp Wich : - compile clean on FreeBSD - bugfix: do not account for IP headers when building MID6 messages PATCHES from Henning Rogge : - join LQ and non-LQ Hello execution paths PATCHES from otti : - rttable-default: configures a new policy routing table for the default route BUGFIXES and PATCHES by Sven-Ola Tuecke : - Windows Vista: add interface metric to SPF computed metric - lqtc-seqno: Optimize check for old seqno numbers in LQTC messages - lqnatthresh: maintain an advantage for the current (NAT) inet gw - fisheye-startup: Changed to MAX_TTL for the first 32 LQTCs - Added and removed files necessary for win32 compile - Fix for hg: do not remove anything in .hg with 'make uberclean' - 104-olsrd-verysmallfix - 105-fix-lq-buffer-quirks - 106-fix-seqnocheck - 110-bmf-v152 - 121-olsrd-fib-metric-approx - 133-fix-lqneigh - 136-optimize-invalidip-check - 138-optimize-message-generation BUGFIX from Lorenz Shori : - Mac OSX compile fixes BUGFIXES and PATCHES by Hannes Gredler - fix not deleted tc entry. - avoid setting routes with an invalid/impossible netmask. - refactoring of TC parsing to kill another pile of malloc()/free()s saving (again) code and especially run.time performance. - RIB Refactoring, Part 2: - avoid the periodical rib-tree insertion - add a FOR_ALL_HNA_RT_ENTRIES() macro for the snmp folks (or any parties who want to walk HNA entries). - add an olsr_cnf option 'flat_fib_metrics' which defaults to TRUE. - fix broken prefix insertion (regression of the RIB refactoring) - squelsh compiler warnings on Mac OSX PATCH by John Hay : - also printout our own HNAs in the dotdraw plugin. PATCH by Patrick McCarty : - fixed compile errors in the BSD port PATCHES by Sven-Ola Tuecke : - 102-olsrd-cvs-fixes.patch: use different buffers in the same printf() - 103-olsrd-rt-exportroute-cleanup.patch: avoid a malloc()ed list of functions - 132-save-the-fish.patch: really save the fish and avoid to forward invalid messages from older olsrd versions - 135-georss-map-for-nameservice.patch: fixes and extensions for the namesaervice plugin - 138-olsrd-fixdotdraw.patch: fix the dot_draw plugin (all to be found on http://download-master.berlin.freifunk.net/sven-ola/nylon/packages/olsrd/files/) - Replaced "which" with a /bin/sh script snippet PATCHES and CLEANUPS by Bernd Petrovitsch - Jens Nachtigall suggested (and reminded) to use olsrd.conf.default.lq as the default installed one. It makes much more sense as - to the best of my(bernd's) knowledge - all larger networks uses the LQ extensions. And new customers should better be pushed in that direction. - with the help of Patrick McCarty , we got olsr to build on OpenBSD again: * OpenBSD'd `sed` is pretty conservative and doesn't understand 's|re|sub|'. So we fall back to the old 's/re/sub/' and quote all '/' and '.' correctly (which was the main reason to use '|'). And while I'm at it: Remove the useless $(CCACHE) from the $(CC) for dependency generation and beautify (read: "$(strip)") $(CPPFLAGS). * OpenBSD needs an explicit "#include " before "#include ". - fixed lib/secure/src/md5.h: This was broken as it had "typedef unsigned long int UINT4;". "unsigned long int" is 8 bytes on x86_64. We are using now the standardized types from . - fixed warnings and improved lib/secure/src/md5.c: * we are using memcpy() and memset() instead of the open-coded loops as suggested * const'ified * added function prototypes for static functions * moved static functions to the top so that their declaration is before their use to allow gcc to inline if only used once. It remains ugly - God knows why there are that so many useless type-casts. - Some minor and trivial cleanup: Added two functions to calculate the ETX value from a struct tc_edge_entry and a struct link_entry, respectively. And use them everywhere. - added http://meshcube.org/nylon/utils/olsr-topology-view.pl into lib/httpinfo/misc as suggested by Jens Nachtigall - Killed "struct olsrd_config *cnf" in src/cfgparser/olsrd_conf.h and replaced it's usage with "olsr_cnf" from src/defs.h. Serious cleanup: olsrd_get_default_cnf() does no longer initialize the global "cnf" variable" but uses a local one which is returned as before. And olsrd_parse_cnf() does no longer return the global variable it is working on. - Merged "struct hna4_entry" and "struct hna6_entry" into "struct local_hna_entry" (as "struct hna_entry" is a different thing) Both have almost the same data (IP address + netmask/prefix) so we use the quite new "struct olsr_ip_prefix" to store it. Also merged the "hna4" and "hna6" pointer in "struct olsr_config" - look at the global "olsr_cnf->ip_version". - added a olsr_ip_prefix_to_string() function - .h file cleanup: def.h does not longer include net_olsr.h because it doesn't needs it. - more type safety: the macros COPY_IP() and COMP_IP are gone and replaced with "=" or similar "normal" C operations. There are also now the inline functions ip4cmp() and ip4equal() to work on "struct in_addr", ip6cmp() and ip6equal() to work on "struct in6_addr" and ipcmp() and ip6equal() to work on "union olsr_ip_addr". Most (or even more precise: almost all) uses of COPY_IP() and COMP_IP() are in "if (olsr_cnf->ip_version) { ... } else { ... }" anyway to there is no reson to copy an IPv4 address effectively with "memcpy(&dst, &src, 4)" or compare with memcmp(&a, &b, 4)" wher the always "4" is stored in a variable inhibiting compiler optimization. There is also the deprecated function genipcopy() mimicking the old typeless COPY_IP() macro for the last few places where a cleanup is needed anyways. There also lots of old macros left over (commented out of course) until we are confident that everything works. And then I will kill them too. - Fixed the misleading definition of "v4" in "struct olsr_ip_addr" fom "olsr_u32_t" (in network-byteorder!) to "struct in_addr". Lots of temporary variables to call inet_ntoa()/inet_ptoa() vanished ..... - We have now ip4_to_string(), ip6_to_string() and olsr_ip_to_string() to print a "struct in_addr", "struct in6_addr" and "union olsr_ip_addr" into a string buffer. - cleanup: olsr_ip_to_string() and similar non-reentrant functions now must get a target buffer. To ease that, there is the "struct ipaddr_str" which is large enough for all of them (read: for an IPv6 address). This also removes the cyclic buffer there. All of these function return a "const char *" which can be directly used for printf(3) and friends. - const'ified more functions - converted the source to UTF-8. - "struct sig_msg" uses an olsr_u8_t for a byte array (and not "char") - force the few inline function to always be inlined. - #ifdef the body of the olsr_print_hna_set() and olsr_print_neighbor_table() if nothing is done - declare "int_addr", "int_netmask" and "int_broadaddr" in "struct interface" as "struct sockaddr_in" since it is that what we actually want there (and it is similar to the IPv6 code). - updated the olsrd.conf.default.lq-fisheye to the Debian-deliverd version after recent discussions olsr-dev@olsr.org - use "inline_avl_comp_ipv4()" in "avl_comp_ipv4()" - clean up the routes on more signals. Basically we want to do this on all signals which terminate the program. - killed a superflous global buffer in src/main.c - made inline functions from avl_walk_{first,last,next,prev} and created "const" versions of it. inline_avl_comp_ipv4() is now also an inline function (and not a macro) - created a typedef's for various function pointers - much easier to read. - cleanup: compare tree->comp (adn other pointers)) to NULL (and not 0) - killed superflous "return"s at the end of void functions - const'ified more parameters in many more functions in the .h and .c files - init-functions with constant or ignored return values are "void" - created a typedef fro the callback in "struct export_route_entry" and using it! - moved the initialization of the {add,chg,del}_kernel_list variables into process_routes.c. So they are now "static" there. - olsr_export_{add,del}_route{,6} are now static in process_routes.c since they are not used elsewhere. - olsr_addroute_add_function() and olsr_deldroute_add_function() were almost identical - made one function out of it. Same for olsr_addroute_del_function() and olsr_deldroute_del_function(). - fixed the sort order in avl_comp_ipv4_prefix(): We compare now the IPv4 values in host byte order (and not network byte order). So the route list in the e.g. httpinfo plugin is now nicely sorted. - fixed and improved the `gcc-warnings` script: * support older gcc's (as on Debian/Sarge) as they have slightly different error messages * removed superflous lines * replaced the call of `sed` with shell built-in features fixing syntax errors on Debian/Sarge * set all locale-relevant variables to "C" (just to be sure) - consolidated ip{4,6,}{cmp,equal}: all are nwo inline functions using only the minimal necessary operations. Thanks to Hannes Gredler and Sven-Ola Tuecke for pointing that out and suggesting the `inline`, respectively. use ip{4,}cmp in lq_avl.[ch] to resue the code. inline_avl_comp_ipv4 is superflous now (and replaced by ip4cmp) and use the global MIN and MAX macro instead of AVLMIN and AVLMAX - killed netmasks from the IPv4 part of the code and use the prefixlen there (similar to thte IPv6 part). Manymore details on http://lists.olsr.org/pipermail/olsr-dev/2007-November/001464.html - removed the superflous "open_ipc" field from the "struct olsrd_config" as it contains only the equivalent of "olsr_cnf->debug_level > 1". - inspired by Sven-Ola Tuecke: avoid a bash'ism (i.e. "OPTS="${OPTS//$opt}") in gcc-warnings and ld-warnings. But we do not replace it with `sed` (since it costs a fork(2) and an exec(3)) but also with shell code which doesn't use any external program. - added configuration file support for "flat fib metrics". 0.5.4 --------------------------------------------------------------------- QUAGGA by Immo 'FaUl' Wehrenberg - updated to svn version 33 BMF PLUGIN by Erik Tromp - updated to 1.5.1 - updated to latest plugin interfaces changes and killed warnings (by Bernd Petrovitsch ) PATCH by Hannes Gredler which rewrites the route handling. To quote him: ---- snip ---- change list: - get rid of separate routing tables for HNA and per-node routes, everything is now unified in an AVL routing tree (&routingtree) - introduce walking macros (OLSR_FOR_ALL_RT_ENTRIES()) that hide the internal structure of the RIB for making life of the plugin authors easier. - get rid of different SPF implementations for LQ and non-LQ code paths. a non-LQ edge is simply substituted with a cost of 1.0 - get rid of host masks - a new data type olsr_prefix is introduced which is basically an ip address plus a prefix length. do not install the metric in the kernel FIB - for the kernel its pointless if the route gets installed with a metric of N or M. we do not need to update the kernel FIB if we have hop count only changes (for example if there is a reroute action further downstream) the only things which triggers a kernel FIB route update is a next hop change (a next hop is neighboring gateway router plus an interface). all OLSR routes are installed with a metric of 2 - separate between rt_entry and rt_path - the former is a route installed in the kernel with an next hop. the latter is a candidate for best path selection after SPF calculation has been done. in the rt_entry we keep a pointer to the best_path and also to the next hop that was installed in the kernel FIB. we always keep all originator of a route, if a route originator goes away we can easy recompute the best path for the route. the next hop in the rt_entry gets only updated upon a successful route_add call - that way we always remember what next hop to delete. stray routes should be history now. - tweak the linked list toolkit to operate on circular lists. - get rid of malloc calls for building the kernel update list. the list node is now embedded in the rt_entry. - introduce three queues (add/chg/del) for kernel updates. - for neighbor route dependency tracking the neighbor routes are queued first or last (depending on which queue you work on) - rework all the plugins which directly manipulate rt entries. - rework the plugins that read from the routing table (most notably nameserver, httpinfo and quagga plugin) - lots of comments that explains the intentions and purpose of this code-piece. non RT related stuff: - use a list rather than a tree for storing the post-SPF results, which further improves the raw-SPF runtime. - add display of SPF runtime (masked behind #ifdef SPF_PROFILING) - http://gredler.at/download/olsrd/neighbor_routes3.diff: This updates the own IP address (read: the main address) after changes (e.g. on `ifup wlan0; sleep 1; ifdown wlan0`) and kills the olsr_fill_routing_table_with_neighbors() function. ---- snip ---- And Sven-Ola Tuecke fixed an instability issue on interface up/down operations (see 102-olsrd-rt-refactoring-fixes.patch below) and a missing initialization. PATCH by Hannes Gredler which "consolidates the link-state database and the spf-calculation in order to calculate routes more efficiently". To quote him (more): ---- snip ---- - use the link-state (tc) database for SPF calculations rather than replicating the notion of vertices and edges for a SPF run. this heavily reduces malloc() calls and shrinks the total CPU load of the route calculation path between 60%-80%. ---- snip ---- PATCHES by Sven-Ola Tuecke to be found on from http://download-master.berlin.freifunk.net/sven-ola/nylon/packages/olsrd/files/ - 102-olsrd-rt-refactoring-fixes.patch Because you changed a lot of basics: It's time to handle a general flaw in the routing system. Plase take a look at chk_if_changed(). This will free() any "struct interface" pointer without warning at any time. This is why it's possile to SEGV olsrd with a simple "ifdown xxx". The patch replaces the (maybe) invalid pointer with an index reference "iif_index". You can always ask the OS for a name. Please note, that I do not have a working BSD toolchain, so I've placed an #error in the IPv6 BSD-part where the author/porter has started to hack something funny. - 110-olsrd-double-wlancard-neigh-hack.patch: This is a hack for Nodes having to wifi cards with the same channel, bssid, IP-Range etc. If two nodes can see each other by means of two possible links (here: two wifi cards with equal config), a bug is triggered with the Neigh-is-SYM detections. This small little hack prevents this. - 112-olsrd-nameservice-fixemptyname.patch: This is an addon to my lat/lon stuff which will prevent olsrd from running (oops?) if no hostname is given and the nameservice plugin is loaded. - 113-olsrd-dyngwplain-pluginvers5.patch: This updates the dyngwplain plugin to the new Plugin Iface - 140-olsrd-arprefreshed.patch: This is a new one. Opens a packet socket and listen to UDP(698), extract the sender MAC and refreshes the ARP cache whith that. Should speedup especially in cases, if you initially try to use a longer routing path which normally triggers a "ARP-Lookup-Chain". - 106-olsrd-nameserviceparams.patch: This patch converts more plugins to the new interface version. - 104-olsrd-policy-routing.patch Reworked this one to discard GPL helper functions. Also checked IPv6 and re-included the IPC hookup. The patch adds a "RtTable [number]" for /etc/olsrd.conf which is simply the Linux policy routing table to use. Defaults to 254 (== main). This patch was modified/clenaed up by to use "#if" instead of "#ifdef" as it's more robust against typos. - 110-olsrd-fixpacketprint.patch, 112-olsrd-nameservice-fixemptyname.patch, 113-olsrd-txtinfo-fixhttpget.patch, 114-olsrd-timeoutlimit.patch, 115-olsrd-nameserviceparamfix.patch and 116-olsrd-fix-pluginparam-addons.patch fixing the compilation warning on 64bit and lots of other improvements. - "Save the fish" patch: Avoid forwarding of packets with too low TTL. This kills lots of packet forwarding storms. NB: The oneliner was applied by hand by BP and formatted to look (in BPs O) more readable. PATCH by Arnd Hannemann olsr_makefile_make_use_of_exename.patch - This patch makes sure that the EXENAME variable of Makefile.inc is used in Makefile. PATCHES by John Hay - update to new FreeBSD WLAN API - do not require /bin/bash, use /bin/sh - Fixed alignment so that olsrd runs on FreeBSD/arm - allow more interface in an IPv6 subnet on FreeBSD - use PREFIX and DESTDIR as all the other Makefile.$OS also for FreeBSD - make txtinfo plugin work with IPv6 PATCH by Andreas Jacobs - fix the loss link quality calculation for "windows size % 4 != 0" PATCH by Acinonyx - Bug fix: include $(TOPDIR)/Makefile.inc at the begin in the Quagga plugin PATCH by David Cornejo - fixed an "+=" of an uninitialized variable (detected with/by the scan.coverty.com). BUG reported by Aaron Kaplan - BSD-xargs doesn't know "-r". PATCHES and CLEANUPS by Bernd Petrovitsch - Made a function from the ME_TO_DOUBLE() macro (in src/mantissa.h). This saves code throughout the code even on i386 and will even more on architectures without floating point units and "-msoft-float". - And the mathemathics in src/mantissa.h is reformulated to minimize floating point operations to save CPU power - especially on embedded devices. - I rewrote the half of src/lq_packet.[ch] which deals with incoming packets. This was triggered with performance output of gcc produced by Sven-Ola Tuecke at CCCamp07. This kills *lots* of (more than) superflous malloc()s and the same number of (free()s). And it also kills some code and copying around of data. - Make it compile without warning with flex-2.5.33 (to be found on Fedora 7 and Gentoo in Sep-2007) again. - converted the dyn_gw plugin to plugin interface version 5 (which leaves the quagga plugion as the last with the old one). - paving the way to activate -Wshadow, much more to do - const-ify parameters here and there - use NULL for pointers (and not "0") - Killed "extern" declarations in (not generated) .c files - Based on a patch by Gianni Costanzi (so credits and thanks have to go there): added OS_CFLAG_PTHREAD Makefile variable since gcc (on Linux) requests this in the manual page. Changes/additions: - I added definitions to all OS-specific Makefile.$OS with the value similar to the value in OS_LIB_PTHREAD (either empty or "-pthread"). - The variable is added to CPPFLAGS (and not CFLAGS) since CPPFLAGS is used for all cpp and gcc calls (and gcc's man page indicates that it sets variables for both of them). 0.5.3 --------------------------------------------------------------------- URGENT BUG FIX Ignacio García Pérez found a serious bug in the dot-draw plugin and identified it's source. BUG FIX The bmf plugin wanted to kill a not-started thread and this causes a segmentation violation. This happens if the old plugin interface support is not compiled in and one uses - or more asccurate: wants to use - the bmf plugin which uses that ATM. Thanks to Cedric Krier for reporting this. DEPENDENCIES FIXED The dependencies (*.d files) are now properly generated and used. And they also dependen on the Makefile in the current directory and the Makefile.inc so that changes there also lead to new compilation. Remember: We support "ccache" so install it to save lot of meaningless recompiles if nothing (as seen by the real C compiler, i.e. after the C preprocessor) has changed. BUILD FIX Linux/IA64 and Linux/HPPA also need "-fPIC". CLEANUPS - olsr_switch does no longer generate warnings - olsr_switch is also built with "build_all" and cleaned with "uberclean" - More "const" all over the place. - More "static" for local functions and variables. - Killed an unnecessary "static" variable. 0.5.2 --------------------------------------------------------------------- URGENT BUG FIX Sven-Ola Tuecke found a serious bug of the class "show stopper" and sent a patch. PLUGIN CLEANUP Plugins handle parameters quite individually (case-sensitive vs case-insensitive, different parsing functions for the same values, etc.). Plugin Interface version 5 now exports a table of { parameter-name, parsing-function, addr-of-storage } and it's size. Common functions should be shared. 0.5.1 --------------------------------------------------------------------- MISC Upgrade to olsr-bmf 1.5 from Erik Tromp latitude/longitude support is now in the nameservice plugin done by Sven-Ola Tuecke added the spf refactoring patch from Hannes Gredler which saves a noteworthy amount of CPU time. To quote him: ---- snip ---- 1. use of an AVL tree as a min-heap implementation as a means for efficient sorting. (the etx metric is used as the key in the candidate tree) 2. next-hop propagation rather than tracking the previous node in olsr_relax() i have changed that model and pre-populate all one-hop neighbors with their own IP adress as 'next-hop' and pull that pointer up once new paths are explored. as a result no walker for counting hops and extracting next-hops is required - it turns out at this is slighly more efficient than the existing behaviour (even with the cache applied). ---- snip ---- CLEANUPS * moved a only locally needed hack from "union olsr_ip_addr" into the only place where it is needed in hashing.c 0.5.0 --------------------------------------------------------------------- APPLIED PATCHES FROM FREIFUNK-FIRMWARE libsmake, dyngwplain, nameservices+services, tzxtinfo, quagga, quagga-routehandler, optimize, fixes from Eric Tromp and Sven-Ola Tuecke, CPU-optimize, secure key, HNA-IP CLEANUPS removed hardcoded limit on the number of interfaces (at least in the Unix part) made Makefile targets much more consistent MISC put Bmf-1.3 plugin into it FreeBSD IPv6 SUPPORT Patch from John Hay applied. BUGFIXES 0.4.10 -------------------------------------------------------------------- OLSR NETWORK SIMULATOR An application called olsr_switch(sorry for the nameclash with the win32 GUI) has been added. If olsrd is ran using the -hint option it can now connect to olsr_switch and be part of a virtual network. This means that multiple instances can be ran at the same host! The olsr_switch application allows the user to define link variables on all viritual links in the network, creating all possible topologies. Read more in the readme file. EXPERIMENTAL FISH EYE ALGORITHM An experimental algorithm for TTL settings on TC messages has been added. Read more in the corresponding README file. OPENBSD SUPPORT olsrd now also compiles on OpenBSD systems. Thanks a lot to Holger Mauermann for the patches! BUILDSYSTEM REWRITE Bruno has rewritten the make system. OS detection is now done automagically and the general design is much improved. IP ADDRESS VALIDATION Olsrd now maintains a set of IP addresses that is considered invalid. Checks against this set is done on all received OLSR packets announced originator addresses. The dataset can be updated dynamically. PLUGIN INTERFACE Updated interface version to 3 and added more noticeable warning for version missmatch. MATH LIB DEPENDENCY The dependency on the math lib came from the use of pow(3) in the mantissa/exponent calculation. The calls to pow in this long forgotten code, was very unnessecarry. The pow calls are replaced with bitwise shifts and -lm is no longer needed. ICMP REDIRECTS ON LINUX On Linux systems "0" is now also written to the all/send_redirects procfile and not only the pr. interface ones. Hopefully this resolves problems reported with systems still sending ICMP redirects. BUGFIXES - Fixed init of IPv6 addrtype variable. It used to be uninitialized, causing it to default to site-local and have some weird side-effects. - Fixed crash when changing IPv6 address at run-time - Fixed a bug that prevented setting willingness 0 in the configfile - Fixed bad handling of missing command line arguments - Did various updates to prevent assertion when a neighbor has changed IP and sends HELLO before its olsrd precess has detected the change. - Fixed return value check on times(2) calls in the scheduler - Fixed bug(s) that could cause crash when an interface was brought down while olsrd was running. - Removed the silent (read: unchecked) hard limit of 16 interfaces. - Compiles now cleanly on 64bit (e.g. x86_64). 0.4.9 --------------------------------------------------------------------- OPTIMIZATIONS The MID database is now also indexed by alias addresses. this makes look-ups of main addresses based on alias addresses _much_ faster. The mid_lookup_main_addr function alone has gone from >30% of the total CPU time used by olsrd to <1%. PLUGIN DEVELOPERS: datatypes for MID entries has been changed. Routing table calculation in the LQ case now uses balanced binary trees instead of linked lists, which makes look-ups much faster. The debug output function olsr_printf() is not used by olsrd internals any more. Instead the macro OLSR_PRINTF is to be used. This macro does debug level testing _before_ doing any function calls(both printf itself and parameters to printf). This is a much more optimized way of doing debug output. In addition olsrd can be built without any debug output code if doing 'make NODEBUG=1'. TIMEOUT OF DATASETS Validity times for dataset entries are now set using the clock_t type (used to be struct timeval). This data is now fetched from the times(2) function instead of gettimeofday(2). This prevents possible problems if the system time is changed. PLUGIN DEVELOPERS: Note that datatypes for close to all dataset entries (link, neighbor, mid, hna, tc etc.) has been changed!! CONFIGURATION FILE Multiple interfaces can now use the same interface configuration block. Example: Interface "if0" "if1" "if2" { ..... } Interface configurations now also support the "Weight" directive. When olsrd finds multiple links to a neighbor it will choose the link going via the interface with the lowest weight. Olsrd normally sets this weight dynamically based on interface characteristics, but if the user wishes to set a fixed weight in a interface(or a group of interfaces), this directive is now available. Moreover, interface configurations now support the "LinkQualityMult" directive. It takes an IP address and a multiplier as arguments. Example: Interface "if0" { [...] LinkQualityMult 192.168.0.1 0.7 LinkQualityMult default 0.5 [...] } The idea is to make certain links via the configured interface artificially worse or better than they really are. The first parameter specifies the IP address of a neighbour interface. The second parameter is the multiplier to be applied to the link to the specified neighbour interface. After we have derived the link quality from the packet loss among the packets received from the specified neighbour interface, we multiply the link quality by the given multiplier. So, the multiplier changes the LQ value that we use when determining the ETX, which is 1 / (LQ * NLQ). If "default" is given as the IP address then the multiplier applies to all links via the configured interface. Note, however, that olsrd only assigns one multiplier to each link. It does so in the following way. * If there is a "LinkQualityMult" line that matches the IP address of the link's neighbour interface, then use the multiplier in this line. * If there isn't any matching line, then look for a "default" line. If there is a "default" line, then use the multiplier in this "default" line. * Otherwise use 1.0, i.e. do not modify the LQ value at all. Hence, a line with an IP address has priority over a "default" line. In the above example, the LQ value of the link between the local interface if0 and the neighbour interface 192.168.0.1 would be multiplied by 0.7. All other links between the local interface if0 and a neighbour interface would be multiplied by 0.5. IPV6 SOCKETS The socket option IPV6_V6ONLY is now set on IPv6 sockets in linux. This means that olsrd will no longer receive IPv4 traffic when running in IPv6 mode. This should enable users to actually run one olsrd instance using IPv6 and one using IPv4 at the same time :) PLUGINS The httpinfo, dyn_gw and dot_draw plugins now all include olsrd headerfiles directly. A plugin should define OLSR_PLUGIN before including olsrd headers. Doing things this way removed the redundant datatype definitions that has so often caused trouble when things has been updated in olsrd. NETBSD SUPPORT olsrd now also compiles on NetBSD systems. Use 'make OS=nbsd' to build. This port is not very well tested and feedback is greatly appreciated. EXPERIMENTAL MULTI-INTERFACE CODE FOR FREEBSD Experimental code using libnet can be compiled in allowing multiple interfaces to be used in FreeBSD. You enable this by compiling using OS=fbsd-ll. You must have libnet-devel installed for this to work (/usr/ports/net/libnet-devel). OTHER UPDATES - WLAN devices are now detected in FreeBSD - First specified interfaces IP is used as main address. - Broadcastflag is not checked on interface if fixed broadcast is set in config. - Removed Linux link layer code as this was not really in use. - Added -nofork command line option BUGFIXES - Link sensing now works according to announced vtime from neighbors. Previously links going symmetric->asymmetric were not necessarily detected until the holding time expired. - A bug in route addition/removal that could lead to routes using GWs being added before the actual route to the GW was set up, has been fixed. - A bug in the interface selection in route calculation has been fixed. New routes are no longer added prior to deleting old ones, since this caused trouble. - A bug in the IPv6 multicast address configuration has been fixed. This caused olsrd not to work with global IPv6 addresses. - A bug in the IPv6 prefix-from IPaddr function has been fixed. This bug caused HNA prefixes to always be calculated to 0. - If a 2-hop neighbor is also a 1-hop neighbor, a bug made olsrd prefer a bad direct link to a better link via an MPR. - If a link or interface lookup failed, olsrd crashed. - Fixed a crash in the LQ packet generation code based on a signed/unsigned integer comparison. 0.4.8 --------------------------------------------------------------------- LICENSE CHANGE Olsrd is now distributed under a BSD style license. We believe olsrd will be better off using this license as it opens up for commercial players to use olsrd freely in their products. In the end this will lead to this kind of users doing serious testing and bug fixing of olsrd. ETX-LIKE LINK QUALITY DETECTION We can now determine the packet loss on a link by looking at the serial numbers of the OLSR messages received from a neighbor. This tells us how many packets get through from our neighbor to us. We use a new extended kind of HELLO messages (LQ_HELLO messages, LQ = link quality) to broadcast the link quality that we have determined on our end of the link to our neighbors. So do our neighbors, and we as well as they end up with an idea of how good the link is in both directions. From the LQ_HELLOs we also learn the link quality between our neighbors and our two-hop neigh- bors. In this way we can select those neighbors as MPRs that have the best links to our two-hop neighbors. To distribute the link quality throughout the network, we use a new extended version of TC messages (LQ_TC messages). They contain the qualities at both ends of each of our links. Nodes can then run Dijkstra's algorithm to find a path between themselves and other nodes that minimizes the packet loss. If the newly introduced "LinkQualityLevel" is set to zero in the configuration file, link quality is not used and the daemon behaves as before, i.e. as specified by the OLSR RFC. If this parameter is set to 1, LQ_HELLOs and LQ_TCs are used instead of HELLOs and TCs, link quality is measured and MPRs are selected based on the link qualities. If this parameter is set to 2, the routing table is additionally calculated based on the link qualities. Setting "LinkQualityLevel" to a non-zero value BREAKS COMPATIBILITY. You will then not be able to participate in RFC-conformant OLSR networks any longer. This is because we use LQ_HELLOs and LQ_TCs instead of HELLOs and TCs in this case. It's best practice to set "LinkQualityLevel" to the same value on all nodes in a network. When determining the quality of a link olsrd only considers a given number of most recent OLSR packets received from its neighbors. By default, olsrd looks at the 10 most recent OLSR packets. This can be changed via the "LinkQualityWinSize" configuration option. Values between 3 and 128 are legal. NEW CONFIGFILE PARSER/FORMAT/SCHEME A whole new config file syntax and parser is introduced with this release. The parser is generated using flex and bison and it is designed to be very modular. The parser can be compiled as either a standalone binary, a shared library or as part of olsrd. This way other applications can parse and generate olsrd configuration files only by linking to the dynamic library. In the new configfile options can be set pr. interface, plugin parameters can be set, more IPC options can be set...and more. The syntax is documented in the olsrd.conf(5) manual page found in the files/ directory. Olsrd internals now uses a single struct, as returned by the config parser, for all configuration in runtime. this means that updating values in this struct will dynamically update olsrd operation. It also means that all configuration is now kept in one place instead of spread all across the place. FREEBSD AND MAC OSX PORT This version offers an initial port of olsrd to FreeBSD and Mac OS X. Like the Windows port it currently does not support IPv6. As this is a very first try at supporting FreeBSD and Mac OS X, this port is probably not as reliable as the Linux version. We'd greatly appreciate feedback and bug reports. To compile you need GNU make. Then simply run "gmake OS=fbsd" to build the executable. NEW MAKEFILE(S) The makefiles used to build olsrd have been rewritten and now includes dependency file generation using makedep. DEBUG OUTPUT Tables are now only printed if changes occur, so there are no longer any periodical output when using a debuglevel >0. A "heartbeat" is now printed to STDOUT(if it is a terminal) in the form of a rotating line to show that olsrd is actually operating. Adding "ClearScreen yes" to the configuration file clears the screen each time before the debug output shows updated information. This makes the debug output easier to read in many cases. "ClearScreen no" is the default, if no "ClearScreen" directive is given in the configuration file. PLUGIN INTERFACE There are some changes in the plugin interface. It is now at version 2. Plugin specific parameters from the configfile using the PlParam option, will now be passed on to plugins. To receive such parameters a plugin must implement a function: int register_olsr_param(char *key, char *value) to which parameter pairs will be passed. NO MORE THREADS Olsrd no longer uses any thread library on its operation. Everything now happens in the main thread allowing for use of olsrd on platforms with no thread library. ACPI SUPPORT IN WILLINGNESS CALCULATION(LINUX) The willingness calculation for Linux, now also supports the more modern ACPI proc interface in addition to APM. This is not well tested and feedback is appreciated! IPC OPTIONS Various options regarding IPC connections can now be set in the configfile. The options are max connections, allowed unicast hosts and allowed net-ranges. CODE REWRITES Much of the message generation and net output code is rewritten. Sending of partial messages should now work 100%. Also TC, MID and HNA messages are now cached for a random amount of time before transmitted - this often leads to the situation where these messages are sent together with an HELLO message, which is highly desirable since it saves network resources. PLUGIN DEVELOPERS must note that the buffers and size variables used in net output is no longer directly accessible! NET OUTPUT CODE REWRITTEN Every interface now has one outputbuffer registered. This allows messages to be "cached" as explained above, so that multiple messages are stacked together. Also the outputbuffer and size are no longer accessible directly, an API is available to plugins(and olsr code). OS DEPENDENT NETWORK INTERFACE The OS dependent network functions are now defined in net_os.h instead of being mixed up with internal network functions in net.h. BUGFIXES A bug that caused the announced ANSN sequence number to never stop being increased when a change in the MPR selector set was detected has been fixed. Another TC related bug that caused timed out TC entries not to be deleted from the routing table in certain cases has also been fixed. These bugs could cause unstable routes. A bug that in many cases caused the wrong routes to be deleted when using IPv6 has been fixed. 0.4.7 --------------------------------------------------------------------- NATIVE WINDOWS GUI AND INSTALLER We now have a native Windows GUI. The GTK+ version is no longer supported on Windows. The new native GUI is pretty compact as it does not require the GTK+ runtime DLLs. In addition to monitoring olsrds state the GUI offers an easy way for novice users to configure olsrd. It's pretty self-explanatory. Have a look at README-WIN32.txt for details. The Windows version now also comes with an installer based on the freely available Nullsoft Scriptable Install System (NSIS). Looks like the Windows port is becoming more and more Windows-ish. :-) WIRELESS INTERFACE DETECTION ON WINDOWS Like the Linux version the Windows port is now able to tell WLAN interfaces from wired interfaces. We can now, for example, set different HELLO intervals for WLAN interfaces and wired interfaces, respectively. ROUTE UPDATES The order of updates of calculated routes is swapped. Now new routes are added prior to deleting old ones. This could fix issues where in some very very few cases one could experiment loss of routes. BUGFIXES There were quite some bugs in IPv6 operation in 0.4.6. These are the bugs that were fixed: - HNA message parsing did not work. - Some IPv6 addresses were printed as IPv4 addresses in the debug output. - The '-dispin' option now works again. - A filedescriptor leak in the IPv6 interface detection caused olsrd to crash. 0.4.6 --------------------------------------------------------------------- WINDOWS PORT! Read the README-WIN32.txt file! DYNAMIC NETWORK INTERFACE UPDATES Network interfaces can now be updated and removed/added at runtime. Olsrd will check all interfaces specified in the config file or on the command-line, every 5 seconds. If updates occur, olsrd will register this and update the necessary data. If interfaces are removed or added, olsrd will detect this and configure the interfaces. If an interface is removed olsrd will continue to check the interface, so if say, a PCMCIA card is removed and later on reinserted(and given the same name), olsrd will detect this and start running on it again. Note that olsrd will now run even if no interfaces are detected. ROUTE CALCULATION UPDATE All 1 hop neighbor addresses that are not directly reachable trough a symmetric link in the link set will now be added with a GW in the routing table. this GW will be an interface address from a registered symmetric link to the neighbor. MID UPDATE Alias addresses are now registered in the link set processing if available. This is not to pretty(since the vtime has to be a mere guess) but it gives faster initial route updates. If a HELLO is received(at initial registration) from an IP that is not the same as the one set as main address in the received HELLO header, then the IP from which the HELLO was received will be registered as an alias of the main address set in the HELLO header. The default vtime is set to 15 secs. CODE RESTRUCTURING All OS dependent interface configuration code is now located in OS/ifnet.c(that would be linux/ifnet.c if using GNU/Linux). The functions are available trough the headerfile src/ifnet.h CODE CLEANUPS - Some timer issues fixed - Got rid of the global socket descriptors - Updated indexing of network interfaces - Introduced a global socket to use for ioctl calls(ioctl_s) - Removed upper limit for interfaces to use - Point-to-point interfaces are now allowed - The main select(2) loop now uses a timeout - A small bugfix in the select fd-set update code - Some bugfixes in the configuration file parsing - stdout/stderr are now set to not be buffered - A bugfix in the MID generation regarding seq. numbering PLUGIN INTERFCAE A new set of functions that are called whenever a change in the interface configuration(update, addition, removal) is made is introduced. These functions are added and removed very much like the ptf functions. Available trough the functions add_ifchgf and del_ifchgf. OBS OBS OBS!!! PLUGIN DEVELOPERS READ THIS!!!! The interface struct(declared in interfaces.h) has changed. Plugin developers must update plugins that uses the interface struct! The headerfile olsr_plugin_io.h which contains the plugin interface commands now contains a revision list where all changes are stated. 0.4.5 --------------------------------------------------------------------- PLUGIN: SECURE OLSR A plugin that generates and checks message signatures is added. Check lib/secure PLUGIN: TOPOLOGY GRAPH A plugin that generates output of the topology in the dot format is added. See lib/dot_draw OPTIMIZATIONS Some optimizations done that should cause fewer route recalculations. BUGFIXES Some bugs reported by Takafumi Tanaka fixed. RESTORATION OF NETWORK SETTINGS Network settings like disabling of ICMP redirects and spoof filter, are now restored at exit by olsrd. RFC COMPLIANCE FIX Nodes would in certain scenarios retransmit messages originating for themselves. This was a RFC incompliance. Reported by Ingmar Baumgart. NON-WLAN TIMERS No longer setting the HELLO interval of non-wlan interfaces as a multiplier of the wlan interval. The interval is set seperatly now. Due to this there are some updates in the configfile imperatives. CODE CLEANUPS Some new macros introduced for table insertion and removal and IP copying and comparison. FRONT END BUGFIXES IPv6 bugfixes in the GUI. 0.4.4 --------------------------------------------------------------------- ROUTE CALCULATION Routes are no longer added via neighbors declaring a willingness of WILL_NEVER. LINK SENSING AND ROUTE CALCULATION Link sensing and route calculation has been updated to handle multiple links between hosts in a sane way. IP SPOOF FILTERING IP spoof filtering is disabled on the interfaces which olsrd runs. These settings are not restored! ICMP REDIRECTS ICMP redirect message generation is disabled on the interfaces which olsrd runs. These settings are not restored! CONFIGFILE OPTIONS FOR MID AND HNA ADDED Options to set the MID and HNA emission intervals and validity time in the configfile added. IPv6 ADDRESS SCOPE Option to set what IPv6 address type(scope) to use in the configfile added. It can be set to either global or site-local. IPv6 MULTICAST Options to set site-local and global multicast addresses in the configfile added. EMISSION INTERVAL FUNCTION Functions to set emission intervals at runtime added. LINK LAYER NOTIFICATIONS If started with the -llinfo switch olsrd will collect and display link-layer information on neighbors. This is no longer limited to one interface. But no action is taken based on this info - and there is a upper limit of 8 neighbors from which this info can be collected pr. interface. This limitation is inherited from the WLAN drivers and is not something imposed by the olsrd code! IPv6 HNA MESSAGE FORMAT IPv6 HNA messages now contains 128-bit netmask instead of prefix. PLUGIN FUNCTIONS Added "packet transform functions" which allow plugins to alter all outgoing OLSR traffic. RESTRUCTURING Moved most headers out of OS dependent directories. The tunneling and link-layer notification interface is not yet separated from the /linux directory. MANUALPAGE A manpage(olsrd(8)) describing olsrd has been created. It is installed when using 'make install'. 0.4.3 --------------------------------------------------------------------- PLUGIN SUPPORT Olsrd now supports runtime-loadable plugins! A couple of example plugins are located in the lib/ directory. Read the README files in the various plugin directories for more info. A directive to load plugins have been added to the configfile as well. Documentation of the plugin interface can be fount at http://www.olsr.org. The plugin interface is designed to be extendable. But it should _always_ be backwards compatible with the interface used in this release! LINK-LAYER NOTIFICATION Some preliminary link-layer notification code has been added. Link quality can be written to stdout if olsrd is started with the -llinfo switch. No action is currently taken based on this info. And info will only be retrieved from the interface named "eth1". This code is not usable for users as of yet! MPR UPDATES Neighbors with willingness set to WILL_ALWAYS is now always added. The MPR selection is optimized as described in RFC3626 section 8.3.1 point 5. MPR BUGS There was a couple of bugs in the MPR selection code. All fixed. LINUX 2.6 BUG Users could not run olsrd on multiple interfaces using the Linux 2.6 kernel series. This is now fixed. MINOR BUGS One small bug in link hysteresis initialization and one in HNA route deletion. MESSAGE-SEQUENCENUMBER INCOMPLIANCE Message-seqnos was implemented on a pr. messagetype and pr. interface basis. This is not RFC3626 compliant and has been updates. All messages and interfaces now uses a global seuencenumber. RANDOM SEQUENCENUMBERS Sequencenumbers are now initialized using a random value. DAEMON MODE Fixes for running olsrd in daemon mode(debug 0). OPTIMIZATIONS Optimizations based on profiling implemented. SANITATION Message size is checked for every message before passing it to the appropriate message parsing function. If the size is bigger than the remaining size of the olsr packet then the message is discarded. GUI FRONT-END Some minor modifications done to the gui. INTERNAL CHANGES Lots of changes in handling of registration and unregistration of scheduler, socketparser, parser and local hna set. Some restructuring and movement of functions. 0.4.2 --------------------------------------------------------------------- No public release 0.4.1 --------------------------------------------------------------------- No public release 0.4.0 --------------------------------------------------------------------- LINK HYSTERESIS Link hysteresis as described in the RFC added. TC REDUNDANCY TC redundancy as described in the RFC added MPR REDUNDANCY MPR redundancy as described in the RFC added SCHEDULER REWRITE The scheduler has been rewritten to register scheduled events(function pointers) dynamically. PARSER REWRITE The parser has been rewritten to register parse functions on a pr. messagetype dynamically MALLOC WRAPPER A wrapper for the malloc(3) syscal has been introduced. olsr_malloc(size_t, const char *) should ALWAYS be used. CODE RESTRUCTURING Lots of restructuring in headerfiles. Linux spesific code moved to subdirectory linux/ FreeBSD code to be put in freebsd/ LOTS of code restructured due to the rexrite of the scheduler and parser. MPR CALCULATION Optimizing the MPR set as suggested in the RFC section 8.3.1 point 5 added. BUGFIXES Some bugs in MPR selection fixed. 0.3.8 --------------------------------------------------------------------- CODE REWRITES HNA code completely rewritten! The old code was really bad! Now it is much cleaner implemented and should work fine. One- and two-hop neighbor list structures rewritten. They now use the same hashed double-linked lists as the rest of the information sets use. CODE RESTRUCTURING Some code restructuring which resulted in the new files: timer.h, mantissa.c, mantissa.h, hashing.c, hashing.h, linux/net.c linux/net.h, linux/kernel_routes.c, linux/kernel_routes.h and some renamed files BUG FIXES The bug causing errormessages on exit is fixed. The bug that caused initial HNA routes in the GUI to display a hopcount of 0 fixed. IPv6 HNA netmasks were all added as /128. It's fixed now. IPv6 Turns out sitelocal address had to be preferred to avoid IPv6 header messing up link-sensing. Bug fixed 0.3.7 --------------------------------------------------------------------- CODE REWRITES The entire TC set and MPR selector set code rewritten. Hashing and double linked lists added to the MID code. Lots of HNA code has been rewritten as well. HNA bugfix When a node lost connectivity to a HNA GW all HNA entries to that gw was deleted. This has been fixed - and HNA entries only gets deleted on timeout now. Other HNA bugs have been fixed as well. But the whole HNA implementation needs a rewrite! Holdingtime BUGfix There was a bug that caused holdingtime not to be properly recalculated when using non-default emission intervals. Forwarding and symmetric neighbors Seems I had misread the RFC on what a 1-hop symmetric neighbor is. Now the link-set is checked when a check for a symmetric neighbor is done. Not the 1 hop neighbor set as it used to be. This way the hack when receiving MID messages could be removed. IPv6 Global addresses are now preferred. Sitelocal addresses are only used if no global addresses are found. There have been problems where the address set in the IP header of IPv6 packets do not match the address chosen by OLSR. GUI - 0.2.5 The GUI is finally updated! It can now handle piggybacked messages and link sensing HELLO message format. 0.3.6 --------------------------------------------------------------------- HNA support using IPv6 HNA now works using IPv6 as well! Just add the network address and prefix in the HNA6 section in the configfile. The IPv6 HNA packets differ some from the IPv4 as they don't send the netmask but the prefix. NEW FILENAME FOR THE BINARY AND CONFIG FILE They are now called olsrd and olsrd.conf. I figured I'd use the olsrd name before somebody else started using it ;-) Config file New options: DEBUG, HNA6 and IPC-CONNECT added to config file. Output A printf-wrapper has been introduced - debug level output handling is much more uniform now. The daemon should run fine in detached mode now(DEBUG 0) GUI front-end The GUI front-end can now connect and disconnect at any time while the daemon is running, if started using the -ipc switch or with IPC set to 'yes' in the configfile. BUGS A small HNA bug fixed. 0.3.5 --------------------------------------------------------------------- Forwarding jitter Forwarding jitter added. Messages are piggybacked if they arrive(and are to be forwarded) while there is data to be forwarded buffered. Added some bugfixes to support parsing of piggybacked messages as well. Route calculation Fixed route calculation so that 2 hop neighbors are added. This smooths changes from 1 hop to 2 hop neighbor out. The old way one had to wait for a TC before the 2 hop neighbors were added. 2 hop neighbor set All neighbors received in HELLO messages are added to the two hop neighborhood. This helps smoothing out the 1-to-2 hop transition as well. MID calculation MID calculation had to be updated due to the registering of two hop neighbors that are already one hop neighbors. They should not be considered when calculating two hop coverage. Optimizations Deletion of possible one hop neighbors registered on non main-addresses when first registering MID info from a node removed. This can not occur due to the fact that registering of neighbor nodes are done on main addresses from link-sensing Option to not forward messages on wired links on which they arrived removed. This is no longer usable to any degree when adding support for piggybacking of forwarded messages is to be implemented. Cleanups Some unused parameters and commandline options were removed. 0.3.3 --------------------------------------------------------------------- TC MESSAGEING Added sending of empty TC messages if all MPR selectors are removed. Empty TC messages are sent for a TC_HOLD_TIME period as described in section 9.3 in the RFC. HNA Fixed HNA route calculations for IPv6. I forgot to upgrade this in 0.3.2 OPTIONS -hnaint and -midint command line optionas added to set the interval of HNA and MID generation. FORWARDING As an optimization messages have not been forwarded on the received interface if this is registered as a non-WLAN interface. This causes problems for people using Ethernet-to-WLAN adapters. This optimization is now turned off by default. It can be activated using the -nofwlan option. BUGS THERE ARE SOME NASTY BUGS IN 0.3.2! Fixed a bug that caused 2 hop neighbors not to time out. Fixed a bug that caused a 1 hop neighbor timeout not to recalculate the routing table. Fixed a small memleak in the MID set Fixed some smaller bugs. IPv6 functioning is not well tested in this release. 0.3.2 --------------------------------------------------------------------- HNA Updated HNA to be RFC compliant. This means that all received HNA tuples are registered and only the subset of unique entries(net/netmask) with the smallest hopcount is inserted into the routing table. Config file User can specify configfile name using the -f switch. Bugs Fixed a link-sensing bug that caused problems when using MID nodes. 0.3.1 --------------------------------------------------------------------- MPR calculation MPR calculation is now based on the willingness announced by nodes. Neighbor set The neighbor set does not have timeouts on entries any more. Creation and deletion of neighbor entries is done from the link-set as suggested in the RFC. Cleanups Gotten rid of a lot of code that became more or less obsolete due to all the changes introduced in 0.3.0. Bugs Fixed a nasty bug concerning the sequence numbering of TC packets. Fixed some bugs regarding MPR calculation - and probably introduced a whole new species when implementing the willingness-based calculation ;-) 0.3.0 --------------------------------------------------------------------- Due to the extensive amount of updates this release is versioned 0.3.0 Duplicate table and forwarding The duplicate table functionality is totally rewritten in 100% RFC compliance. The forward algorithm specified in the RFC is implemented this meant rewriting much of the packet processing code. The daemon also forwards unknown packettypes now. Link sensing and neighbor processing Link sensing and neighbor processing was done in the same operation in the old code. Link sensing is now a mechanism of its own which is 100% RFC compliant. Neighbor processing and HELLO generation has been partly rewritten to be RFC compliant. Neighbors are now registered as either SYN or NOT_SYM. The NOT_NEIGH, SYM_NEIGH and MPR_NEIGH values are only used when building HELLO messages. Links are in one of the following states: UNSPEC_LINK, ASYM_LINK or SYM_LINK. HELLO messages now advertise link status of neighbors on the interface the message is transmitted. Willingness A node now dynamically calculates willingness based on powersource and possibly battery power. If the node is AC powered it announces a willingness of 6. If batterypowered the willingness is calculated as: P / 26 Where P is percentage of power left. Configuration file The daemon now tries to read its configuration from the file /etc/uolsrd.conf A "standard" configuration file is installed when doing 'make install'. This file should be edited to fit your needs. Command-line options can still be used to override the configuration form the file(ore if no config file is present). The -f switch can also be used to specify a configuration file. Willingness If AdvancedPowerManagemant(APM) is supported on your system the willingness of the node is dynamically calculated based upon the powerstatus of the node. MPR calculation based upon willingness is not done as of yet. TC ANSN A bugs in the TC processing fixed. HNA Some serious HNA bugs fixed. These bugs caused a node to always choos the gateway with the larges hopcout :) More seriously - a bug caused looping of HNA messages in certain scenarios. Package sequence numbers These were added. Not much use as of now - but they're there(as specified in the RFC). Broadcast address Users can now specify the broadcast address to use. Useful if one wishes to use the 255.255.255.255 broadcast. 0.2.5 --------------------------------------------------------------------- Htime and Vtime Htime and Vtime processing and handling added. Holding times used to be a static value for all nodes. Now every node can signal its vlidity time to others. To achieve this mantissa/exponent calculation functionality was added. Messages now include Vtime(and Htime in HELLO) values in mantissa/exponent format instead of just zero. These values are as stated above, used as holding time for nodes. the GUI should be upgraded as well... Jitter The use of jitter in message generation intervals vere fixed. 0.2.4 --------------------------------------------------------------------- Seqno bugs Some bugs concerning sequence numbers in HELLO and MID message handling was fixed. Newly registered nodes in the neighbor and MID sets were initialized with a seqno of 0. When using a "wraparound" sequencenumber check(as defined in olsr_protocol.h) this can produce errors if a new node joins a network where existing nodes has seqnos >0x00FF. IPv6 related bugs Some checks and copying of node addresses where done using sizeof(u_olsr32_t) which is 32 bits. This caused only the 32 firs bits of IPv6 addresses to be copied and checked.
