It has been a request that multiple libnl versions should be installabe
in parallel.
In order to achieve this, the basename of the library was changed to
libnl-3 which reflects the 3rd generation of libnl APIs. It also means
that release based library versioning is left behind and libtool
versioning is used instead.
Projects using pkgconfig will automatically link against the new library
basename and will not notice a difference.
The SO versioning is based on the glib model:
current := 100 * minor + micro - revision
revision := revision
age := age (number of backwards compatible versions)
Finally got rid of all the qdisc/class/cls code duplication in
the tc module API. The API takes care of allocation/freeing the
tc object specific data.
I hope I got it right this time.
Adds a family argument which allows to request link dumps for a certain
address family. This allows to f.e. dump ipv6 specific statistics and data.
nl-link-list --family inet6
- parse IFLA_IFALIAS if available
- provides API to access/change ifalias
rtnl_link_get_ifalias(link)
rtnl_link_set_ifalias(link, alias)
- extends nl-link-set to test functionality
Manually editing etc/libnl/classid before adding tc objects is a pain.
This patch adds code to attempt auto generating a unique tc id which
will then be assigned to the provided name and added to the classid
file.
This will make the following commands work with prior definitions of
the names "top" and "test"
sudo sbin/nl-qdisc-add --dev eth0 --parent root --id top htb
sudo sbin/nl-class-add --dev eth0 --parent top --id test htb --rate 100mbit
It will generate the following ids automatically:
4001: top
4001:1 test
- Fixes a bunch of bugs related to ematches
- Adds support for the nbyte ematch
- Adds a bison/flex parser for ematch expressions, expressions
may look like this:
ip.length > 256 && pattern(ip6.src = 3ffe::/16)
documenation on syntax follows
- adds ematch support to the basic classifier (--ematch EXPR)
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.
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.
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/$name.so.
Syntax:
nl-class-add --dev eth2 --parent 1: --id 1:1 htb --rate 100mbit
nl-class-add --update --dev eth2 --id 1:1 htb --rate 200mbit
Adds a cli based tool to add/update/replace qdiscs. This tool requires
each qdisc to be supported via a dynamic loadable module in
pkglibdir/cli/qdisc/$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
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.
