2008-11-05[SCSI] zfcp: Fix hexdump data in s390dbf tracesChristof Schmitt
Fix multiple problems found in the hexdump data: - length calculation was wrong, traces were incomplete - FC payloads were dumped in different record than the output function tried to read - minor fixes in output - allow complete RSCN traces (up to 1024 bytes according to spec) Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: Swen Schillig <swen@vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2008-11-05[SCSI] zfcp: fix erp timeout cleanup for port open requestsMartin Petermann
If an open port fsf request times out (in erp) the corresponding erp_action member of the fsf request need to set to NULL. If the port structure will be removed later-on there will be still a reference in the fsf request to the non existing erp_action otherwise.

2008-11-05[SCSI] zfcp: Wait for port scan to complete when setting adapter onlineChristof Schmitt
Attaching a unit immediately after setting the adapter online should be possible. The problem right now is that the port_scan runs from a workqueue and has not finished when the set_online call returns and the sysfs structures for the ports are not available yet. Fix that by waiting for the port scan to complete.

2008-11-05[SCSI] zfcp: Fix request list handling in error pathChristof Schmitt
Fix the handling of the request list in the error path: - Use irqsave for the lock as in the good path. - Before removing the request, check if it is still in the list, a call to dismiss_all might have changed the list in between. - zfcp_qdio_send does not change the queue counters on failure, trying revert something is wrong, so remove this.

2008-11-05[SCSI] zfcp: Dont clear reference from SCSI device to unitChristof Schmitt
It is possible that a remote port has a problem, the SCSI device gets deleted after the rport timeout and then the timeout for pending SCSI commands trigger an abort. For this case, don't delete the reference from the SCSI device to the zfcp unit, so that we can still have the reference to issue an abort request.

2008-11-05[SCSI] qla2xxx: Return a FAILED status when abort mailbox-command fails.Michael Reed
Mike Reed noted (https://bugzilla.novell.com/show_bug.cgi?id=421330) that the driver was incorrectly returning a SUCCESS status if the driver's request to the firmware to abort a command failed. By doing so, the mid-layer believed, incorrectly, that the command has completed and has been returned (ultimately clearing scsi_cmnd.request_buffer) yet the driver still has the command. What should correctly happen is a mid-layer escalation (device-reset, etc.) of recovery during which the driver will eventually return the outstanding commands to the mid-layer.

2008-11-05[SCSI] megaraid: fix mega_internal_command oopsFUJITA Tomonori
scsi_cmnd->cmnd was changed from a static array to a pointer post 2.6.25. It breaks mega_internal_command(): static int mega_internal_command(adapter_t *adapter, megacmd_t *mc, mega_passthru *pthru) { ... scb = &adapter->int_scb; memset(scb, 0, sizeof(scb_t)); scmd = &adapter->int_scmd; memset(scmd, 0, sizeof(Scsi_Cmnd)); sdev = kzalloc(sizeof(struct scsi_device), GFP_KERNEL); scmd->device = sdev; scmd->device->host = adapter->host; scmd->host_scribble = (void *)scb; scmd->cmnd[0] = MEGA_INTERNAL_CMD; mega_internal_command() uses scsi_cmnd allocated internally so scmd->cmnd is NULL here. This patch adds a static array for cdb to adapter_t and uses it here. This also uses scsi_allocate_command/scsi_free_command, the recommended way to allocate struct scsi_cmnd since the driver might use sense_buffer in struct scsi_cmnd.

2008-11-04sata_nv: fix generic, nf2/3 detection regressionTejun Heo
All three flavors of sata_nv's are different in how their hardreset behaves. * generic: Hardreset is not reliable. Link often doesn't come online after hardreset. * nf2/3: A little bit better - link comes online with longer debounce timing. However, nf2/3 can't reliable wait for the first D2H Register FIS, so it can't wait for device readiness or classify the device after hardreset. Follow-up SRST required. * ck804: Hardreset finally works. The core layer change to prefer hardreset and follow up changes exposed the above issues and caused various detection regressions for all three flavors. This patch, hopefully, fixes all the known issues and should make sata_nv error handling more reliable. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-11-04sata_promise: add ATA engine reset to reset opsMikael Pettersson
Promise ATA engines need to be reset when errors occur. That's currently done for errors detected by sata_promise itself, but it's not done for errors like timeouts detected outside of the low-level driver. The effect of this omission is that a timeout tends to result in a sequence of failed COMRESETs after which libata EH gives up and disables the port. At that point the port's ATA engine hangs and even reloading the driver will not resume it. To fix this, make sata_promise override ->hardreset on SATA ports with code which calls pdc_reset_port() on the port in question before calling libata's hardreset. PATA ports don't use ->hardreset, so for those we override ->softreset instead. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-11-03mv643xx_eth: fix SMI bus access timeoutsLennert Buytenhek
The mv643xx_eth mii bus implementation uses wait_event_timeout() to wait for SMI completion interrupts. If wait_event_timeout() would return zero, mv643xx_eth would conclude that the SMI access timed out, but this is not necessarily true -- wait_event_timeout() can also return zero in the case where the SMI completion interrupt did happen in time but where it took longer than the requested timeout for the process performing the SMI access to be scheduled again. This would lead to occasional SMI access timeouts when the system would be under heavy load. The fix is to ignore the return value of wait_event_timeout(), and to re-check the SMI done bit after wait_event_timeout() returns to determine whether or not the SMI access timed out.

2008-11-03ftrace: use kretprobe trampoline name to test in outputSteven Rostedt
Impact: ia64+tracing build fix When a function is kprobed, the return address is set to the kprobe_trampoline, or something similar. This caused the output of the trace to look confusing when the parent seemed to be this "kprobe_trampoline" function. To fix this, Abhishek Sagar added a test of the instruction pointer of the parent to see if it matched the kprobe_trampoline. If it did, the output would print a "[unknown/kretprobe'd]" instead. Unfortunately, not all archs do this the same way, and the trampoline function may not be exported, which causes failures in builds. This patch will compare the name instead of the pointer to see if it matches. This prevents us from depending on a function from being exported, and should work on all archs. The worst that can happen is that an arch might use a different name and then we go back to the confusing output. At least the arch will still build.

2008-11-03XFRM: copy_to_user_kmaddress() reports local address twiceArnaud Ebalard
While adding support for MIGRATE/KMADDRESS in strongSwan (as specified in draft-ebalard-mext-pfkey-enhanced-migrate-00), Andreas Steffen noticed that XFRMA_KMADDRESS attribute passed to userland contains the local address twice (remote provides local address instead of remote one). This bug in copy_to_user_kmaddress() affects only key managers that use native XFRM interface (key managers that use PF_KEY are not affected). For the record, the bug was in the initial changeset I posted which added support for KMADDRESS (13c1d18931ebb5cf407cb348ef2cd6284d68902d 'xfrm: MIGRATE enhancements (draft-ebalard-mext-pfkey-enhanced-migrate)').

2008-11-03tracing, alpha: undefined reference to `save_stack_trace'Al Viro
Impact: build fix on !stacktrace architectures only select STACKTRACE on architectures that have STACKTRACE_SUPPORT ... since we also need to ifdef out the guts of ftrace_trace_stack(). We also want to disallow setting TRACE_ITER_STACKTRACE in trace_flags on such configs, but that can wait.

2008-11-03SMC91x: Fix compilation on some platforms.David S. Miller
This reverts 51ac3beffd4afaea4350526cf01fe74aaff25eff ('SMC91x: delete unused local variable "lp"') and adds __maybe_unused markers to these (potentially) unused variables. The issue is that in some configurations SMC_IO_SHIFT evaluates to '(lp->io_shift)', but in some others it's plain '0'. Based upon a build failure report from Manuel Lauss. Signed-off-by: David S.
