* ixgbe: Fix VF rate limiting to correctly account for more queues per VFAlexander Duyck2012-09-161-41/+59
| | | | | | | | | | | | | This change fixes the assumptions of the rate limiting code that previously assumed that each VF would only ever have 2 queues. This update makes it so that we now use a queues per pool value that is determined based on the VMDq feature mask.

* ixgbe: Fix ordering of things so that PF correctly configures its VLANsAlexander Duyck2012-09-162-4/+10
| | | | | | | | | | | | | | | The PF was not correctly registering any of its VLANs. As a result any VLAN tagged traffic from the VF would not be delivered to the PF because the VLAN was never assigned to the PF pool. In addition the VF was not allowed to receive traffic from VLAN 0 if it was allowed to receive untagged frames. This change corrects that so that it will correctly receive traffic from VLAN 0.

* scsi_netlink: Remove dead and buggy codeEric W. Biederman2012-09-132-564/+15Star
| | | | | | | | | | | | | | | | | | | | | | The scsi netlink code confuses the netlink port id with a process id, going so far as to read NETLINK_CREDS(skb)->pid instead of the correct NETLINK_CB(skb).pid. Fortunately it does not matter because nothing registers to respond to scsi netlink requests. The only interesting use of the scsi_netlink interface is fc_host_post_vendor_event which sends a netlink multicast message. Since nothing registers to handle scsi netlink messages kill all of the registration logic, while retaining the same error handling behavior preserving the userspace visible behavior and removing all of the confused code that thought a netlink port id was a process id. This was tested with a kernel allyesconfig build which had no problems. Cc: James Bottomley <James.Bottomley@parallels.com> Cc: James Smart <James.Smart@Emulex.Com> Signed-off-by: "Eric W.

* bnx2x: Link Flap AvoidanceYaniv Rosner2012-09-133-48/+437
| | | | | | | | | | | | | | | | | | Various flows in the bnx2x driver cause a link-flap - if the link is up, it would be toggled down (after a mac/phy reset) and then taken back up. In many of these cases, there is no need to do cause such a flap, as the associated flows should not actually affect the link. This patch adds the 'Link Flap Avoidance' mechanism, which allows the driver to better determine if a given flow requires a link change, and thus minimize the number of link flaps caused by the driver.

| | | | | | | | | | | | | | | | | | | | | | Refactoring the bind code lets us use a common driver_info struct for all supported devices, simplifying the code a bit. The real advantage is that devices using the CDC ECM interface layout now also can be added dynamically using the new_id sysfs interface. This simplifies testing of new devices.

* | net: qmi_wwan: increase max QMI message size to 4096Bjørn Mork2012-09-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QMI requests exceeding 1500 bytes are possible and device firmware does not handle fragmented messages very well. It is therefore necessary to increase the maximum message size from the current 512 bytes. The protocol message size limit is not documented in any publicly known source, but the out of tree driver from CodeAurora use 4 kB. This is therefore chosen as the new arbitrary default until the real limit is known. This should allow any QMI message to be transmitted without fragmentation, fixing known issues with GPS assistance data upload. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

* | scm: Don't use struct ucred in NETLINK_CB and struct scm_cookie.Eric W. Biederman2012-09-074-12/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Passing uids and gids on NETLINK_CB from a process in one user namespace to a process in another user namespace can result in the wrong uid or gid being presented to userspace. Avoid that problem by passing kuids and kgids instead. - define struct scm_creds for use in scm_cookie and netlink_skb_parms that holds uid and gid information in kuid_t and kgid_t. - Modify scm_set_cred to fill out scm_creds by heand instead of using cred_to_ucred to fill out struct ucred. This conversion ensures userspace does not get incorrect uid or gid values to look at. - Modify scm_recv to convert from struct scm_creds to struct ucred before copying credential values to userspace. - Modify __scm_send to populate struct scm_creds on in the scm_cookie, instead of just copying struct ucred from userspace. - Modify netlink_sendmsg to copy scm_creds instead of struct ucred into the NETLINK_CB.
