* netlink: change return-value logic of netlink_broadcast()Pablo Neira Ayuso2009-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] ibmvfc: Fix DMA mapping leak on memory allocation failureBrian King2009-01-25
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] qla4xxx: do not reuse session when connecting to different target portMike Christie2009-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Here's > a snippet of a READ_10 scsi_cmnd upon completion by the storage The problem is caused by: commit b60af5b0adf0da24c673598c8d3fb4d4189a15ce Author: Alan Stern <stern@rowland.harvard.edu> Date: Mon Nov 3 15:56:47 2008 -0500 [SCSI] simplify scsi_io_completion() Because scsi_release_buffers() is called before commands that go through the ACTION_RETRY and ACTION_DELAYED_RETRY legs are requeued. 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).

| * [SCSI] fc transport: restore missing dev_loss_tmo callback to LLDDJames Smart2009-01-06
| | | | | | | | | | | | | | | | | | | | | | When we reworked the transport for the rport lifetimes, in cases where the rport was reused as a container for tgt id bindings, we inadvertantly removed the callback to the driver indicating that dev_loss_tmo had fired. This patch restores that functionality. Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
| * [SCSI] aha152x_cs: Fix regression that keeps driver from using shared interruptsLarry Finger2009-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | At some point since 2.6.22, the aha152x_cs driver stopped working and started erring on load with the following messages: kernel: pcmcia: request for exclusive IRQ could not be fulfilled. kernel: pcmcia: the driver needs updating to supported shared IRQ lines. With the following change, the driver works with shared IRQs.

| * [SCSI] sd: Correctly handle 6-byte commands with DIXMartin K. Petersen2009-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | DIF does not work with 6-byte commands so we previously ignored those commands when preparing a request. However, DIX does not need RDPROTECT/WRPROTECT to be set and 6-byte commands are consequently perfectly valid in host-only mode. This patch fixes a problem where we would set the wrong DIX operation when issuing commands to a legacy disk. Signed-off-by: Martin K.

Also, we are now using EILSEQ to indicate integrity errors to the upper layers (as opposed to regular EIO failures). This allows filesystems to inspect buffers and decide whether to retry the I/O.

| * [SCSI] scsi_lib: don't decrement busy counters when inserting commandsJames Bottomley2009-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A bug was introduced by commit b60af5b0adf0da24c673598c8d3fb4d4189a15ce Author: Alan Stern <stern@rowland.harvard.edu> Date: Mon Nov 3 15:56:47 2008 -0500 [SCSI] simplify scsi_io_completion() because the simplification uses scsi_queue_insert(). The problem with this function is that it expects to be called from the completion path while the command is still outstanding, so it decrements the device and host busy counts to do the requeue. The problem is that scsi_io_completion() is a path executed well after these counts have *already* been decremented, leading to a double decrement if the command goes down any error path leading to ACTION_DELAYED_RETRY. The fix is to allow a private function __scsi_queue_insert() with a flag to say whether the busy counters should be decremented. This is made static to scsi_lib.c to discourage other use.
