2009-02-05netlink: change return-value logic of netlink_broadcast()Pablo Neira Ayuso
Currently, netlink_broadcast() reports errors to the caller if no messages at all were delivered: 1) If, at least, one message has been delivered correctly, returns 0. 2) Otherwise, if no messages at all were delivered due to skb_clone() failure, return -ENOBUFS. 3) Otherwise, if there are no listeners, return -ESRCH. With this patch, the caller knows if the delivery of any of the messages to the listeners have failed: 1) If it fails to deliver any message (for whatever reason), return -ENOBUFS. 2) Otherwise, if all messages were delivered OK, returns 0. 3) Otherwise, if no listeners, return -ESRCH. In the current ctnetlink code and in Netfilter in general, we can add reliable logging and connection tracking event delivery by dropping the packets whose events were not successfully delivered over Netlink. Of course, this option would be settable via /proc as this approach reduces performance (in terms of filtered connections per seconds by a stateful firewall) but providing reliable logging and event delivery (for conntrackd) in return. This patch also changes some clients of netlink_broadcast() that may report ENOBUFS errors via printk. This error handling is not of any help. Instead, the userspace daemons that are listening to those netlink messages should resync themselves with the kernel-side if they hit ENOBUFS. BTW, netlink_broadcast() clients include those that call cn_netlink_send(), nlmsg_multicast() and genlmsg_multicast() since they internally call netlink_broadcast() and return its error value.

2009-01-25[SCSI] ibmvfc: Fix DMA mapping leak on memory allocation failureBrian King
There is currently a DMA mapping leak that can occur in the ibmvfc driver if we fail to allocate a scatterlist. Fix this by unmapping the scatterlist in the failure path. Additionally, only log an error for a scatterlist allocation failure if the log level is greater than the default, since this can occur when running Active Memory Sharing and this is not considered an error.

Commit f78badb1ae07e7f8b835ab2ea0b456ed3fc4caf4 ([SCSI] fc transport: pre-emptively terminate i/o upon dev_loss_tmo timeout) changed the callback semantics of dev_loss_tmo and terminate_rport_io such that repeated calls could be made.

When clearing the flash device's SR, the comment is incorrect... clearing the SR is 2 steps: 1. the SR protect bit is 1, so the first write zero clears only that bit, 2. the SR protect bit is now 0, so the next write zero clears the remaining bits.

Pre-ISP81XX parts (including ISP24xx and ISP25xx) could contain a firmware image within a segment of flash, driver would fallback to loading this firmware if the request-firmware interface failed (userspace .bin file). Moving forward, all ISP81XX parts will ship with a suggested-to-be-used firmware image within flash which all driver should first attempt to load. If the flash firmware load fails, the driver will then fallback to loading firmware via the request-firmware interface (ql8100_fw.bin).

2009-01-25[SCSI] qla4xxx: do not reuse session when connecting to different target portMike Christie
qla4xxx does not check the I_T nexus values correctly so it ends up creating one session to the target. If a portal should disappear or they should be reported in different order the driver will think it is already logged in when it could now be speaking to a different target portal or accessing it through a different initiator port (iscsi initiator port is not tied to hardware and is just the initiator name plus isid so you could end up with multiple ports through one host). This patch has the driver check the iscsi scsi port values when matching sessions (we do not check the initiator name because that is static). It results in a portal from each target portal group getting logged into instead of just one per target. In the future the firmware should hopefully send us notification of other sessions that are created to other portals within the same tpgt and the sessions should have different isids.

I've kept the ioctl controls for per-queue LRO switches. However, we should not encourage anyone to use these. Because of that, I've also kept the skb construction code in cxgb3.

__scsi_device_lookup_by_target() will always return the first sdev with a matching LUN, regardless of the state. However, when this sdev is in SDEV_DEL scsi_device_lookup_by_target() will ignore this device and so any valid device on the list after the deleted device will never be found. So we have to modify __scsi_device_lookup_by_target() to skip any device in SDEV_DEL.

However, they're not re-prepared, so nothing ever reallocates the buffer resources to them. Fix this by releasing the buffers only if we're not going to go down these legs (but scsi_release_buffers() on all legs including two in scsi_end_request(); this latter needs a special version __scsi_release_buffers() because the final one can be called after the request has been freed, so the bidi test in scsi_release_buffers(), which touches the request has to be skipped).
