* hfi1_pkey_validation_pma - It validates PKEYs for incoming PMA MAD packets.

* @ibp: IB port data

* @in_mad: MAD packet with header and data
|
|
* @in_wc: Work completion data such as source LID, port number, etc.
|
|
*
|
|
* These are all the possible logic rules for validating a pkey:
|
|
*
|
|
* a) If pkey neither FULL_MGMT_P_KEY nor LIM_MGMT_P_KEY,
|
|
* and NOT self-originated packet:
|
|
* Drop MAD packet as it should always be part of the
|
|
* management partition unless it's a self-originated packet.
|
|
*
|
|
* b) If pkey_index -> FULL_MGMT_P_KEY, and LIM_MGMT_P_KEY in pkey table:
|
|
* The packet is coming from a management node and the receiving node
|
|
* is also a management node, so it is safe for the packet to go through.
|
|
*
|
|
* c) If pkey_index -> FULL_MGMT_P_KEY, and LIM_MGMT_P_KEY is NOT in pkey table:
|
|
* Drop the packet as LIM_MGMT_P_KEY should always be in the pkey table.
|
|
* It could be an FM misconfiguration.
|
|
*
|
|
* d) If pkey_index -> LIM_MGMT_P_KEY and FULL_MGMT_P_KEY is NOT in pkey table:
|
|
* It is safe for the packet to go through since a non-management node is
|
|
* talking to another non-management node.
|
|
*
|
|
* e) If pkey_index -> LIM_MGMT_P_KEY and FULL_MGMT_P_KEY in pkey table:
|
|
* Drop the packet because a non-management node is talking to a
|
|
* management node, and it could be an attack.
|
|
*
|
|
* For the implementation, these rules can be simplied to only checking
|
|
* for (a) and (e). There's no need to check for rule (b) as
|
|
* the packet doesn't need to be dropped. Rule (c) is not possible in
|
|
* the driver as LIM_MGMT_P_KEY is always in the pkey table.
|
|
*
|
|
* Return:
|
|
* 0 - pkey is okay, -EINVAL it's a bad pkey
