| |
This is a port to 2.6.25-mm1 of Eric Biederman's patchset to implement tagged directories in sysfs. This patchset was discussed a few months ago on lkml@.
I re-post this patchset as most of network namespace work has been merged in net-2.6.26 and the issue is it is currently easy to test because of this missing piece. (today sysfs must be disabled to test netns).
This feature is needed for network namespaces where we have to be able to have multiple network devices with the same name in different network namespaces.
On top of that, the final patch from Serge Hallyn also implements tagging for user namespaces.
Here is the announcement Eric wrote back in December to introduce his patchset:
" Now that we have network namespace support merged it is time to revisit the sysfs support so we can remove the dependency on !SYSFS.
[...]
The bulk of the patches are the changes to allow multiple sysfs superblocks.
Then comes the tagged directory sysfs support which uses information captured at mount time to decide which object with which tag will appear in a directory.
Then the support for renaming and deleting objects where the source may be ambiguous because of tagging.
Then finally the network namespace support so it is clear how all of this tied together. "
Regards, Benjamin
