net: dcbnl: check correct ops in dcbnl_ieee_set()

2011-03-02T23:04:33+00:00

The incorrect ops routine was being tested for in
DCB_ATTR_IEEE_PFC attributes. This patch corrects
it.

Currently, every driver implementing ieee_setets also
implements ieee_setpfc so this bug is not actualized
yet.

Don't potentially dereference NULL in net/dcb/dcbnl.c:dcbnl_getapp()

2011-02-13T19:21:14+00:00

nla_nest_start() may return NULL. If it does then we'll blow up in
nla_nest_end() when we dereference the pointer.

net: dcb: application priority is per net_device

2011-02-13T19:02:39+00:00

The app_data priority may not be the same for all net devices.
In order for stacks with application notifiers to identify the
specific net device dcb_app_type should be passed in the ptr.

This allows handlers to use dev_get_by_name() to pin priority
to net devices.

dcbnl: make get_app handling symmetric for IEEE and CEE DCBx

2011-01-24T23:19:55+00:00

The IEEE get/set app handlers use generic routines and do not
require the net_device to implement the dcbnl_ops routines. This
patch makes it symmetric so user space and drivers do not have
to handle the CEE version and IEEE DCBx versions differently.

dcb: use after free in dcb_flushapp()

2011-01-06T19:16:54+00:00

The original code has a use after free bug because it's not using the
_safe() version of the list_for_each_entry() macro.

dcb: unlock on error in dcbnl_ieee_get()

2011-01-06T19:16:54+00:00

There is a "goto nla_put_failure" hidden inside the NLA_PUT() macro, but
we're holding the dcb_lock so we need to unlock first.

dcbnl: adding DCBX feature flags get-set

2010-12-31T18:50:54+00:00

Adding a pair of set-get routines to dcbnl for setting the negotiation
flags of the various DCB features. Conforms to the CEE flavor of DCBX
The user sets these flags (enable, advertise, willing) for each feature
to be used by the DCBX engine. The 'get' routine returns which of the
features is enabled after the negotiation.

This patch is dependent on the following patches:
[net-next-2.6 PATCH 1/3] dcbnl: add support for ieee8021Qaz attributes
[net-next-2.6 PATCH 2/3] dcbnl: add appliction tlv handlers
[net-next-2.6 PATCH 3/3] net_dcb: add application notifiers

dcbnl: adding DCBX engine capability

2010-12-31T18:50:54+00:00

Adding an optional DCBX capability and a pair for get-set routines for
setting the device DCBX mode. The DCBX capability is a bit field of
supported attributes. The user is expected to set the DCBX mode with a
subset of the advertised attributes.

This patch is dependent on the following patches:
[net-next-2.6 PATCH 1/3] dcbnl: add support for ieee8021Qaz attributes
[net-next-2.6 PATCH 2/3] dcbnl: add appliction tlv handlers
[net-next-2.6 PATCH 3/3] net_dcb: add application notifiers
