- avoid unncessary name change requests
The kernel does not check if the specified IFNAME is different
from the current name. It assumes that if IFNAME and ifindex
are both specified, a name change is requested. Therefore avoid
specyfing IFNAME if ifindex is provided and original and new
name are identical.
- move link building to own function (to allow link add later on)
- error if immutable changes have been made
- better documentation
Provide nl_pickup() to pick up an answer from a netlink request and parse
it using the supplied parser.
Add rtnl_link_get_kernel() which sends an RTM_GETLINK to the kernel to
fetch a single link directly from the kernel. This can be faster than
dumping the whole table, especially if lots of links are configured.
- removed dead functions in header files
- deprecated rtnl_class_foreach_*() functions due to their missing
handling possibility of OOM situations
- improved API documentation
Deprecated the functions rtnl_qdisc_change() and
rtnl_qdisc_build_change_request() for their lack of being able to
specify flags. The new functions rtnl_qdisc_update() and
rtnl_qdisc_build_update_request() may be used instead. The old
functions are still available though. However, rtnl_qdisc_update()
no longer implies NLM_F_REPLACE, it has to specified implicitely
to allow updating a qdisc without risking to replace another qdisc.
Included detailed documentation of qdisc addition/update/deletion.
Introduced APPBUG() macro to let application developer know of
API abuse.
Their usage is not completely safe, it is not possible to handle
the out of memory situation of the allocate filter. It is very
unlikely for this to cause any problem though.
The functions are still accessible but gcc will warn about their
deprecation.
This commit adds some missing files (some header files, the files below
/etc and the bison/flex files) to the distribution tarball to ensure
that libnl can be built from the tarballs created using "make dist".
It also adds some incantations to properly generate the flex and bison
output since the generated output is no longer shipped in the tarball.
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.
Note: The code for this is not upstream yet.
Extends the link api to allow address family modules to fill a link
message and implements a AF_INET address family link module which
uses the new interface.
This feature isn't upstream yet. It's required to test a patch in
my local tree.
Makes the link parser understand IFLA_AF_SPEC and call the address
family specific parser.
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
Introduces a new API to handle address familiy specific link data such as
IFLA_PROTINFO. It provides entry hooks for parsing IFLA_PROTINFO attributes
and allows to include the parsed data when a link object is dumped.
- 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
