* Packet location updatesThomas Graf2010-10-263-9/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch includes various bugfixes in the packet location parser. Namely it removes two memory leaks if parsing fails. The parser is correctly quit if an allocation error occurs and it is no longer possible to add duplicates. It removes the possibility to differ between net and host byteorder. This is better done in the actual classifiers as it makes more sense to specify this together with the value to compare against. The patch also extends the API to add new packet locations via rtnl_pktloc_add(). It introduces reference counting, therefore you now have to give back packet locations with rtnl_pktloc_put() after looking them up with rtnl_pktloc_lookup(). But you are allowed to keep using them if the packet location file has been reread. The packet location file now also understands "eth", "ip", and "tcp" for "link", "net", and "transport". A --list option has been added to nl-pktloc-lookup to list all packet location definitions A --u32=VALUE option has been added to let nl-pktloc-lookup print the definition in iproute2's u32 selector style. A manual page has been written for nl-pktloc-lookup. Finally, nl-pktloc-lookup has been made installable.

* Unified TC attributes interfaceThomas Graf2010-10-2611-106/+146
| | | | | | | | | | | | | | | | | | | | | | | | So far all common tc atttributes were accessed via specific functions, i.e. rtnl_class_set_parent(), rtnl_qdisc_set_parent(), rtnl_cls_set_parent() which implied a lot of code duplication. Since all tc objects are derived from struct rtnl_tc and these common attributes are already stored in there this patch removes all type specific functions and makes rtnl_tc_* attribute functions public. rtnl_qdisc_set_parent(qdisc, 10); becomes: rtnl_tc_set_parent((struct rtnl_tc *) qdisc, 10); This patch also adds the following new attributes to tc objects therefore removing them as tc specific attributes: - mtu - mpu - overhead This allows for the rate table calculations to be unified as well taking into account the new kernel behavior to take care of overhead automatically.
* nl-class-list toolThomas Graf2010-10-203-1/+118
| | | | Same syntax as nl-qdisc-list
* nl-class-delete toolThomas Graf2010-10-204-1/+152
| | | | Tool based on nl-qdisc-delete to delete traffic classes.
* Make nl-qdisc-delete installableThomas Graf2010-10-203-31/+65
| | | | | Fixes nl_cli_confirm() and adds a check enforcing --yes before deleting all qdiscs on all devices.
* Remove NL_DUMP_ENV codeThomas Graf2010-10-202-3/+0
| | | | | | | Dumping objects as environment variables has never been implemented completely and only increases the size of the library for no real purpose. Integration into scripts is better achieved by implementing a python module anyway.
* make nl-qdisc-list installableThomas Graf2010-10-202-21/+24
| | | | Also improves usability of nl-qdisc-list
* nl-class-add toolThomas Graf2010-10-207-2/+240
| | | | | | | | | | Adds a cli based tool to add/update traffic classes. This tool requires each class to be supported via the respetive qdisc module in pkglibdir/cli/qdisc/$name.so. Syntax: nl-class-add --dev eth2 --parent 1: --id 1:1 htb --rate 100mbit nl-class-add --update --dev eth2 --id 1:1 htb --rate 200mbit
* remove obsolete nl-qdisc-add codeThomas Graf2010-10-191-196/+0

* classid databaseThomas Graf2010-10-193-1/+85
| | | | | | | | | A database to resolve qdisc/class names to classid values and vice versa. The function rtnl_tc_handle2str() and rtnl_tc_str2handle() will resolve names automatically. A CLI based tool nl-classid-lookup is provided to integrate the database into existing iproute2 scripts.
* nl-qdisc-add toolThomas Graf2010-10-194-3/+233
| | | | | | | | | | | | Adds a cli based tool to add/update/replace qdiscs. This tool requires each qdisc to be supported via a dynamic loadable module in pkglibdir/cli/qdisc/$name.so. So far HTB and blackhole have been implemented. Syntax: nl-qdisc-add --dev eth2 --parent root --id 1: htb --r2q=5 nl-qdisc-add --update-only --dev eth2 --id 1: htb --r2q=10
* - Prepare for 2.1.x treeThomas Graf2010-10-141-3/+1

* automake: add ${top_builddir}/include to AM_CFLAGSAndreas Bießmann2010-10-132-2/+2
| | | | | | | | | | | This patch enables out-of-source builds like this $ cd builddir && src_dir/configure && make Before this patch there was an error about missing netlink/version.h which is built by automake in top_builddir rather than top_srcdir which is already in include search path.

* Use CPPFLAGSThomas Graf2010-10-131-1/+1

* Put preprocessor definitions in AM_CPPFLAGSMatthew L. Creech2010-10-131-1/+1
| | | | | | | | When an alternate kernel header include directory is added in CPPFLAGS, the libnl build fails. This is because the local copy of kernel headers is added in AM_CFLAGS, which gets included after CPPFLAGS in the automake-generated makefile. Switching to AM_CPPFLAGS fixes the problems.

* src/nf-queue.c: cleanup and improve performance of test program for NF_QUEUEKarl Hiramoto2010-04-191-1/+31
| | | | | | | | | | | | | | | | | | | | | | | | * Fix filename in file header * If the kernel or netlink socket becomes over loaded, the kernel starts printing error messages like: nf_queue: full at 1024 entries, dropping packets(s). Dropped: 1 nf_queue: full at 1024 entries, dropping packets(s). Dropped: 2 nf_queue: full at 1024 entries, dropping packets(s). Dropped: 3 So detect out of order packet ID's and set the NF_ACCEPT verdictÂ, so they will be removed from the kernel queue. * increase socket buffer to improve performance without these changes sending more than 100 KB/s over tcp HTTP lo(localhost) was difficult on my core2 duo machine, due to so many dropped packets. After these changes over 150 MB/s was easy. * improve help text Signed-off-by: Karl Hiramoto <karl@hiramoto.org>
* CLI - Command Line Interface LibraryThomas Graf2009-12-1662-1454/+1212

* libnl: fix automake breakagePatrick McHardy2009-11-101-2/+18

* Big routing code rework (API/ABI BREAK!)Thomas Graf2008-04-2912-305/+636
| | | | | | | | | | Adds all missing routing attributes and brings the routing related code to a working state. In the process the API was broken several times with the justification that nobody is using this code yet. The changes include new example code which is also a prototype for how plain CLI tools could look like to control routes.

* [LIBNL]: Split up nfnetlink_log into log and msg objectsPatrick McHardy2008-02-071-9/+46
| | | | | | | | | | | | | | Split the nfnetlink_log code into two seperate objects, "netfilter/log" to represent logging instances and "netfilter/log_msg" to represent log messages. Also perform some function name unification for consistency with other libnl object types, mainly renaming nfnl_log_build_*_msg to nfnl_log_build_*_request. This changes the API in an incompatible way, but since this feature is new and the libnl netfilter headers haven't been installed so far, there shouldn't be any users affected by this.
