This file states changes as of version 0.2.4:
0.6.1 --------------------------------------------------------------------
Bugfix release for 0.6.0
Markus Kittenberger <[email protected]>
- Major bugfix for the neighbor table when a neighbor gets a new main IP.
- add /interface command to txtinfo, allow multiple commands per request
Henning Rogge <[email protected]>
- wait up to four seconds for aquiring the OLSRd lock. This helps to
shutdown OLSRd with a script and restart it at once (kill <pid> is
asynchrone, and kill -w is not available in busybox)
- add md5 has of all source/headers into version string
Mitar<[email protected]>
- lot's of small changes for Android. Slowly Android gets a fully
supported platform for OLSRd.
and a lot more small bugfixes. Read GIT changelog at http://olsr.org/git
to see a complete history.
0.6.0 --------------------------------------------------------------------
Change in version number system. No more -rcX for release candidates and
-rX for bugfix releases. In future bugfix releases or updates of plugins
will increase the third digit of the version string while feature releases
will increase the first and/or the second one.
Markus Kittenberger <[email protected]>
Henning Rogge <[email protected]>
- added NIIT kernel module support for sending IPv4 traffic over
IPv6 mesh networks. See README-Olsr-Extensions for more information.
- added SmartGateway support. OLSRd can now automatically build
IPIP tunnels towards the gateway to prevent gateway flapping.
See README-Olsr-Extensions for more information.
- complete rewrite of linux netlink routing code. New code should be
more understandable and easier to debug/improve.
Teco Boots <[email protected]>
- new dyngw plugin. More flexible and more features.
- new p2pd plugin (generalized mdns plugin)
Vasilis Tsiligiannis <[email protected]>
- new version of quagga plugin (with IPv6 support !)
Sven-Ola Tuecke <[email protected]>
- fixes for improved uClibc support
- fixes for better linux kernel 2.4 support
Saverio Proto <[email protected]>
- new mdns plugin. (backport from master branch)
Eric Tromps <[email protected]>
- new version of bmf plugin. NO pthreads are necessary anymore
and a lot more small bugfixes. Read GIT changelog at http://olsr.org/git
to see a complete history.
0.5.6-r8 ---------------------------------------------------------------------
Alina Friedrichsen <[email protected]>
- patch for using deticated output socket for OLSR packages. This allows
to set the src-ip of OLSR packages, which is useful for interfaces
with multiple IPs
Bruce Ford <[email protected]>
- fixes for compiling olsrd for win32
Henning Rogge <[email protected]>
- fix for memoryleak during MID processing
- patch series for "network logoff" of OLSRd, other nodes now get
notified if an OLSR node switch down to remove it from their database.
- cleanup of naming conventions for settings src/dst-ips of OLSR-packets
for ipv4/6. See example config files.
- patch to ignore HNA4 for IPv6 and HNA6 for IPv4
Markus Kittenberger <[email protected]>
- patch series for MID handling cleanup
- compiletime switch for txtinfo to always allow localhost access
- add "InterfaceDefaults" section to config files to allow setting values
which are shared by all interfaces but can be overwritten in specific
config file settings
- patch series to allow OLSRd handle multiple config files
(multiple "-f <cfgfile>" options)
0.5.6 ---------------------------------------------------------------------
PATCHES and BUGFIXES from Henning Rogge <[email protected]>
- Bugfix for fragmented TC sequence numbers
- eliminate second timer for edge garbage collection (aka border code).
- fix SPF bug
- fix for jitter calculation
- refactor linkset code
- add netsimpcap, a network simulation device
- parser refactoring
- fix for possible overflow in fpm plugin
- prevent Originator-IP from changing during runtime
- fix several compiler warnings
- fix hanging TC entry from lost onehop neighbor
- fix drop package with same seqno in etx_ff
- fix segfault in parsing HNA package with bad netmask
- fix avl_comparator for route_paths
- fix alignment problem in packet buffers
- fix: segfault in neighbor/neighbor-2 table
- fix: lqmult default parsing
- HACK: MinTCVTime parameter hack for Berlin FF network...
feel free to ask on the mailing list.
- add Watchdog plugin
- add explicit runtime lock for OLSR.
- remove lq-hysteresis for tc on the receiver side.
- enhance protection against malformed packages to prevent
OLSR parsing uninitialized data. Thank you Markus and Keks for the LONG
debugging session
- block tc-redundancy 0/1, it doesn't work with the current dijkstra code
- convert httpinfo/txtinfo/dotdraw to nonblocking and autobuf to
prevent blocking outgoing connections
- fix some bugs with lq-mult
- fix bug in duplicate set sequencenumber handling
- add Debian/KFreeBSD support (Thanks to Holger Levsen and friends for help)
- fix segfault in 'interface lost' monitor
- add LQ hysteresis to etx-ff metric
PATCH from Markus Kittenberger <[email protected]>:
- txtinfo plugin: add more http options
- allow configuration of OLSR UDP port
- allow configuration of proto Tag for Routes (RtProto)
- add fallback policy rule (priority 65536) if RtTable is used,
to ensure that routes can be added to this table
- resolve many error conditions while adding routes to the linux kernel
(Warning this will also delete any conflicting routes made by other routing daemons or admins)
- interface modes mesh (default) and ether (no retransmit of olsr-messages back into a broadcastdomain)
- fix olsr_times() to handle different OS implementations (Linux, BSD, OS X)
- fix several compiler warnings
- fix olsr_times() to handle different OS implementations (Linux, BSD, OS X)
- create policy rule later during startup
- send MID also with one interface, if its ip different from originator-id
- linux rtnetlink code cleanup
- workaround: generate routes to single hop neighbours on the fly when inserting routes via them
(active only with fib_metric=flat)
- testing: insert routes with source-ip set to originator ip
- testing: syslog numbering (e.g. useful to detect lost syslog messages when using remote-syslog)
- testing: custom library path (default /usr/testlib)
Testing features must be activated in olsr_cfg.h before compiling olsrd.
This features are used to run a test network in Vienna parallel to the existing
OLSR network.
- more RT-Netlink cleanups and fixes
- backport of timejump patch from TIP
- Add detection for vanishing interfaces to Linux netlink code
- fix incorret route sorting on new neighbours. use only delete and add/change avl tree,
instead of 3 trees
- learn neighbours interface alias adress from received hellos
PATCHES from Hannes Gredler <[email protected]>:
- add small valgrind howto
- remove the per tc_edge timer

same Hello message
- ignore UNSPEC_LINKS during MPR lookup
- broken MID route handling: we also check the data structures for routing,
even if a MID entry exists.

- Replaced "which" with a /bin/sh script snippet
PATCHES and CLEANUPS by Bernd Petrovitsch <[email protected]>
- Jens Nachtigall <[email protected]> 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 <[email protected]>, 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 <sys/types.h>" before
"#include <netinet/in.h>".
- 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 <inttypes.h>.
- 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 <[email protected]>
- 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 [email protected]
- 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
<[email protected]> and Sven-Ola Tuecke <[email protected]> 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 <[email protected]>
- updated to svn version 33
BMF PLUGIN by Erik Tromp <[email protected]>
- updated to 1.5.1
- updated to latest plugin interfaces changes and killed warnings (by Bernd
Petrovitsch <[email protected]>)
PATCH by Hannes Gredler <[email protected]> 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 <[email protected]> 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 <[email protected]> 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 <[email protected]> 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 <[email protected]> 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 <[email protected]>
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 <[email protected]>
- 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 <[email protected]>
- fix the loss link quality calculation for "windows size % 4 != 0"
PATCH by Acinonyx <[email protected]>
- Bug fix: include $(TOPDIR)/Makefile.inc at the begin in the Quagga plugin
PATCH by David Cornejo <[email protected]>
- fixed an "+=" of an uninitialized variable (detected with/by the
scan.coverty.com).
BUG reported by Aaron Kaplan <[email protected]>
- BSD-xargs doesn't know "-r".
PATCHES and CLEANUPS by Bernd Petrovitsch <[email protected]>
- Made a function from the ME_TO_DOUBLE() macro (in src/mantissa.h).
This saves code throughout the code even on i386 and will even more
on architectures without floating point units and "-msoft-float".
- And the mathemathics in src/mantissa.h is reformulated to minimize
floating point operations to save CPU power - especially on embedded
devices.
- I rewrote the half of src/lq_packet.[ch] which deals with incoming
packets. This was triggered with performance output of gcc produced
by Sven-Ola Tuecke at CCCamp07.
This kills *lots* of (more than) superflous malloc()s and the same
number of (free()s). And it also kills some code and copying around of
data.
- Make it compile without warning with flex-2.5.33 (to be found on Fedora 7
and Gentoo in Sep-2007) again.
- converted the dyn_gw plugin to plugin interface version 5 (which leaves
the quagga plugion as the last with the old one).
- paving the way to activate -Wshadow, much more to do
- const-ify parameters here and there
- use NULL for pointers (and not "0")
- Killed "extern" declarations in (not generated) .c files
- Based on a patch by Gianni Costanzi <[email protected]> (so credits
and thanks have to go there):
added OS_CFLAG_PTHREAD Makefile variable since gcc (on Linux) requests this
in the manual page.
Changes/additions:
- I added definitions to all OS-specific Makefile.$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 <[email protected]> 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 <[email protected]> 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 <[email protected]>
latitude/longitude support is now in the nameservice plugin done by
Sven-Ola Tuecke <[email protected]>
added the spf refactoring patch from Hannes Gredler <[email protected]> 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.

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.
