* [SCSI] libfc: fcoe_transport_create fails in single-CPU environmentSteven Clark2012-03-281-2/+12
| | | | | | | | | | | | | Starting fcoe fails at fcoe_transport_create when attempting to allocate a pool of 4K exchanges on a 64-bit single-CPU environment because the call to __alloc_percpu() is greater than the max of 32K. This patch reduces the number of exchanges to fit within the maximum allowed space.

* [SCSI] fcoe: reduce contention for fcoe_rx_list lock [v2]Neil Horman2012-03-281-8/+14
| | | | | | | | | | | | | | | | | | There is potentially lots of contention for the rx_list_lock. On a cpu that is receiving lots of fcoe traffic, the softirq context has to add and release the lock for every frame it receives, as does the receiving per-cpu thread. We can reduce this contention somewhat by altering the per-cpu threads loop such that when traffic is detected on the fcoe_rx_list, we splice it to a temporary list. In this way, we can process multiple skbs while only having to acquire and release the fcoe_rx_list lock once.

* [SCSI] fcoe: remove frame dropping code from fcoe_percpu_cleanNeil Horman2012-03-281-19/+3
| | | | | | | | | | | | | commit e7a51997dad4e17395be1209970e18d2e9305b24 ([SCSI] fcoe: flush per-cpu thread work when destroying interface) added a skb flush to the fcoe_rx_list, which ensures that we push any pending frames on the list through the per-cpu receive thread. Because of this, its redundant to lock and scan the list first, dropping any arriving frames.

* [SCSI] libfcoe: Support extra MAC descriptor to be used as FCoE MACBhanu Prakash Gollapudi2012-03-282-6/+26
| | | | | | | | | | | | | | Some switch implementations (eg., HP virtual connect FlexFabric) send two MAC descriptors in FIP FLOGI response, with first MAC descriptor (granted_mac) used as FPMA, and the second one (fcoe_mac) used as destination address for sending/receiving FCoE packets. fip_mac continues to be used for FIP traffic. This patch introduces fcoe_mac in fcoe_fcf structure. For regular switches, both fcoe_mac and fip_mac will be the same. For the switches that send additional MAC descriptor, fcoe_mac is updated.

* [SCSI] fcoe: Ensure fcoe_recv_frame is always called in process contextNeil Horman2012-03-281-17/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 859b7b649ab58ee5cbfb761491317d5b315c1b0f introduced the ability to call fcoe_recv_frame in softirq context. While this is beneficial to performance, its not safe to do, as it breaks the serialization of access to the lport structure (i.e. when an fcoe interface is being torn down, theres no way to serialize the teardown effort with the completion of receieve operations occuring in softirq context. As a result, lport (and other) data structures can be read and modified in parallel leading to corruption. Most notable is the vport list, which is protected by a mutex, that will cause a panic if a softirq receive while said mutex is locked. Additionaly, the ema_list, discussed here: http://lists.open-fcoe.org/pipermail/devel/2012-February/011947.html Can be corrupted if a list traversal occurs in softirq context at the same time as a list delete in process context. And generally the lport state variables will not be stable, and may lead to unpredictable results. The most direct fix is to remove the bits from the above commit that allowed fcoe_recv_frame to be called in softirq context. We just force all frames to be handled by the per-cpu rx threads. This will allow the fcoe_if_destroy's use of fcoe_percpu_clean to function properly, ensuring that no frames are being received while the lport is being torn down.

* [SCSI] st: expand ability to write immediate filemarksLee Duncan2012-03-274-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | The st tape driver recently added the MTWEOFI ioctl, which writes a tape filemark (EOF), like the MTWEOF ioctl, except that MTWEOFI returns immediately. This makes certain applications, like backup software, run much more quickly on buffered tape drives. Since legacy applications do not know about this new MTWEOFI ioctl, this patch adds a new ioctl option that tells the st driver to return immediately when writing an EOF (i.e. a filemark). This new flag is much like the existing flag that tells the st driver to perform writes (and certain other IOs) immediately, but this new flag only applies to writing EOFs. This new feature is controlled via the MTSETDRVBUFFER ioctl, using the newly-defined MT_ST_NOWAIT_EOF flag. Use of this new feature is displayed via the sysfs tape "options" attribute. The st documentation was updated to mention this new flag, as well as the problems that can occur from using it.
