Affected: All code that uses connector, in kernel and out of mainline The connector, as it is today, does not allow the in kernel receiving parts to do any checks on privileges of a message's sender. I know, there are not many out there that like connector, but as long as it is in the kernel, we have to fix the security issues it has! Please either drop connector, or someone who feels a bit responsible and has our beloved dictator's blessing, PLEASE PLEASE PLEASE take this into your tree, and send the pull request to Linus. Patches 1 to 4 are already Acked-by Evgeny, the connector's maintainer. Patches 5 to 7 are the obvious fixes to the connector user's code. For convenience these patches are also available as git tree: git://git.drbd.org/linux-2.6-drbd.git connector-fix -Phil Philipp Reisner (8): connector: Keep the skb in cn_callback_data connector: Provide the sender's credentials to the callback connector/dm: Fixed a compilation warning connector: Removed the destruct_data callback since it is always kfree_skb() dm/connector: Only process connector packages from privileged processes dst/connector: Disallow unpliviged users to configure dst pohmelfs/connector: Disallow unpliviged users to configure pohmelfs uvesafb/connector: Disallow unpliviged users to send netlink packets Documentation/connector/cn_test.c | 2 +- Documentation/connector/connector.txt | 8 ++++---- drivers/connector/cn_queue.c | 12 +++++++----- drivers/connector/connector.c | 22 ++++++++-------------- drivers/md/dm-log-userspace-transfer.c | 6 ++++-- drivers/staging/dst/dcore.c | 7 ++++++- drivers/staging/pohmelfs/config.c | 5 ++++- drivers/video/uvesafb.c | 5 ++++- drivers/w1/w1_netlink.c | 2 +- include/linux/connector.h | 11 ++++------- 10 files changed, 43 insertions(+), 37 deletions(-) -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
