dcbnl : Fix misleading dcb_app->priority explanation

2014-07-31T00:21:05Z

Current explanation of dcb_app->priority is wrong. It says priority is expected to be a 3-bit unsigned integer which is only true when working with DCBx-IEEE. Use of dcb_app->priority by DCBx-CEE expects it to be 802.1p user priority bitmap. Updated accordingly This affects the cxgb4 driver, but I will post those changes as part of a larger changeset shortly.

net: Use netlink_ns_capable to verify the permisions of netlink messages

2014-04-24T17:44:54Z

It is possible by passing a netlink socket to a more privileged executable and then to fool that executable into writing to the socket data that happens to be valid netlink message to do something that privileged executable did not intend to do. To keep this from happening replace bare capable and ns_capable calls with netlink_capable, netlink_net_calls and netlink_ns_capable calls. Which act the same as the previous calls except they verify that the opener of the socket had the desired permissions as well. Reported-by: Andy Lutomirski Signed-off-by: "Eric W.

dcb: use __dev_get_by_name instead of dev_get_by_name to find interface

2014-01-15T02:50:46Z

The following call chain indicates that dcb_doit() is protected under rtnl_lock. So if we use __dev_get_by_name() instead of dev_get_by_name() to find interface handlers in it, this would help us avoid to change interface reference counter. rtnetlink_rcv() rtnl_lock() netlink_rcv_skb() dcb_doit() rtnl_unlock() Cc: John Fastabend Signed-off-by: Ying Xue Signed-off-by: David S.

net/*: Fix FSF address in file headers

2013-12-06T17:37:57Z

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes.

rtnetlink: Remove passing of attributes into rtnl_doit functions

2013-03-22T14:31:16Z

With decnet converted, we can finally get rid of rta_buf and its computations around it. It also gets rid of the minimal header length verification since all message handlers do that explicitly anyway. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

dcbnl: fix various netlink info leaks

2013-03-10T09:19:26Z

The dcb netlink interface leaks stack memory in various places: * perm_addr[] buffer is only filled at max with 12 of the 32 bytes but copied completely, * no in-kernel driver fills all fields of an IEEE 802.1Qaz subcommand, so we're leaking up to 58 bytes for ieee_ets structs, up to 136 bytes for ieee_pfc structs, etc., * the same is true for CEE -- no in-kernel driver fills the whole struct, Prevent all of the above stack info leaks by properly initializing the buffers/structures involved.

net: Allow DCBnl to use other namespaces besides init_net

2012-12-10T19:09:01Z

Allow DCB and net namespace to work together. This is useful if you have containers that are bound to 'phys' interfaces that want to also manage their DCB attributes. The net namespace is taken from sock_net(skb->sk) of the netlink skb. CC: "Eric W. Biederman" Signed-off-by: John Fastabend Signed-off-by: David S. Miller
