2010-01-28ahci: disable SNotification capability for ich8Shaohua Li
commit 1b677afda44f7882b7e257d6f025d006ec5d14f9 upstream. I obseved there is a sata_async_notification() for every ahci interrupt. But the async notification does nothing (this is hard disk drive and no pmp). This cause cpu wastes some time on sntf register access. It appears ICH AHCI doesn't support SNotification register, but the controller reports it does. After quirking it, the async notification disappears. PS. it appears all ICH don't support SNotification register from ICH manual, don't know if we need quirk all ICH. I don't have machines with all kinds of ICH.

2010-01-28PCI: AER: fix aer inject result in kernel oopsSong Youquan
commit 46256f83d0d066f99ffde547f27473dfd2a78009 upstream. If the BIOS does not export _OSC to allow OS take over the PCIe AER, the pcie aer driver will not initialize the aer service. However, the aer_inject driver does not check this scenario, which results in a kernel oops when injecting an aer error into OS.

2010-01-28libfc: remote port gets stuck in restart state without really restartingAbhijeet Joglekar
commit 5543c72e2bbb30e5ba5938b18ec26617b8b3fb04 upstream. We ran into a scenario where a remote port goes into RESTART state, but never gets added to scsi transport. The running vmcore showed the following: a) Port was in RESTART state b) rdata->event was STOP c) no work gets scheduled for the remote work to fc_rport_work After this point, shut/no-shut of the remote port did not cause the port to get re-discovered. The port would move betwen DELETE and RESTART states, but the event would always be STOP, no work would get scheduled to fc_rport_work and the port would not get added to scsi_transport. The problem is that rdata->event is not set to NONE after a port is restarted. After this point, no more work gets scheduled for the remote port since new work is scheduled only if rdata->event is non-NONE. So, the event and state keep changing, but fc_rport_work does not get scheduled to actually handle the event. Here's a transition of states that explains the above observation: ) Port is first in READY State, event is NONE 2) RSCN on shut, port goes to DELETED, event is stop 3) Before fc_rport_work runs, RSCN on no-shut, port goes to RESTART, event is still STOP 4) fc_rport_work gets scheduled, removes the port from transport, sees state as RESTART, begins the PLOGI state machine, event remains as STOP (event NOT changed to NONE, this is the bug) 5) Plogi state machine completes, port state goes to READY, event goes to READY, but no work is scheduled since event was STOP (non-NONE) before. Fc_rport_work is not scheduled, port remains in READY state, but is not added to transport. Things are broken at this point. Libfc rport is ready, but no transport rport created. 6) now a shut causes port state to change to DELETE, event to change to STOP, no work gets scheduled 7) no-shut causes port state to change to RESTART, event remains at STOP, no work gets scheduled (6) and (7) now get repeated everytime we do shut/no-shut. No way to get out of this state. Fcc reset does not help too. Only way to get out is to load/unload module. Fix is to set rdata->event to NONE while processing the STOP/LOGO/FAILED events, inside the discovery and rport locks.

2010-01-28libfc: fix free of fc_rport_priv with timer pendingJoe Eykholt
commit b4a9c7ede96e90f7b1ec009ce7256059295e76df upstream. Timer crashes were caused by freeing a struct fc_rport_priv with a timer pending, causing the timer facility list to be corrupted. This was during FC uplink flap tests with a lot of targets. After discovery, we were doing an PLOGI on an rdata that was in DELETE state but not yet removed from the lookup list. This moved the rdata from DELETE state to PLOGI state. If the PLOGI exchange allocation failed and needed to be retried, the timer scheduling could race with the free being done by fc_rport_work(). When fc_rport_login() is called on a rport in DELETE state, move it to a new state RESTART. In fc_rport_work, when handling a LOGO, STOPPED or FAILED event, look for restart state. In the RESTART case, don't take the rdata off the list and after the transport remote port is deleted and exchanges are reset, re-login to the remote port. Note that the new RESTART state also corrects a problem we had when re-discovering a port that had moved to DELETE state. In that case, a new rdata was created, but the old rdata would do an exchange manager reset affecting the FC_ID for both the new rdata and old rdata. With the new state, the new port isn't logged into until after any old exchanges are reset.

2010-01-28libfc: fix memory corruption caused by double frees and bad error handlingChris Leech
commit 8f550f937e9fdafa5c37e348e214aecec851ef3f upstream. I was running into several different panics under stress, which I traced down to a few different possible slab corruption issues in error handling paths. I have not yet looked into why these exchange sends fail, but with these fixes my test system is much more stable under stress than before. fc_elsct_send() could fail and either leave the passed in frame intact (failure in fc_ct/els_fill) or the frame could have been freed if the failure was is fc_exch_seq_send(). The caller had no way of knowing, and there was a potential double free in the error handling in fc_fcp_rec(). Make fc_elsct_send() always free the frame before returning, and remove the fc_frame_free() call in fc_fcp_rec(). While fc_exch_seq_send() did always consume the frame, there were double free bugs in the error handling of fc_fcp_cmd_send() and fc_fcp_srr() as well. Numerous calls to error handling routines (fc_disc_error(), fc_lport_error(), fc_rport_error_retry() ) were passing in a frame pointer that had already been freed in the case of an error. I have changed the call sites to pass in a NULL pointer, but there may be more appropriate error codes to use. Question: Why do these error routines take a frame pointer anyway? I understand passing in a pointer encoded error to the response handlers, but the error routines take no action on a valid pointer and should never be called that way.

2010-01-28libfc: Fix wrong scsi return status under FC_DATA_UNDRUNYi Zou
commit 4347fa66878e079766258bc0d077c350cb31a799 upstream. This bug is exposed when there is a link flap in LLD. Particularly, when it happens right after a SCSI write command is sent out, no FCP_DATA is sent, causing fsp->status_code to be set as FC_DATA_UNDRUN in fc_fcp_complete_locked even no SCSI status is received. Consequently, fc_io_compl treats this as DID_OK. This results in SCSI returning successful to the initial I/O request even there is no DATA actually sent. Particularly, if you run an I/O tool w/ data verification on, the read back for verification is gonna fail. This is fixed here by checking when FC_DATA_UNDRUN happens, SCSI status is received w/ FC_SRB_RCV_STATUS set in fsp->state.

It seems invalid to set port_state under lock, then expect it to remain set after releasing the lock. Another thread called fc_remote_port_add() when the lock was released, changing the port_state. This patch removes the BUG_ON and moves the test of the port_state to inside the host_lock. It's been running for several weeks now with no ill effect.

2010-01-28HID: fixup quirk for NCR devicesJiri Kosina
commit 5b915d9e6dc3d22fedde91dfef1cb1a8fa9a1870 upstream. NCR devices are terminally broken by design -- they claim themselves to contain proper input applications in their HID report descriptor, but behave very badly if treated in standard way. According to NCR developers, the devices get confused when queried for reports in a standard way, rendering them unusable. NCR is shipping application called "RPSL" that can be used to drive these devices through hiddev, under the assumption that in-kernel driver doesn't perform initial report query. If it does, neither in-kernel nor hiddev-based driver can operate with these devices any more. Introduce a quirk that skips the report query for all NCR devices. The previous NOGET quirk was wrong and had been introduced because I misunderstood the nature of brokenness of these devices.

2010-01-28iscsi class: modify handling of replacement timeoutMike Christie
commit fdd46dcbe4468a1f47a2cc9be442d11c3d21dd68 upstream. This patch modifies the replacement/recovery_timeout so it works more like the fc fast io fail tmo. If userspace tries to set the replacement/recovery_timeout to less than zero, we will turn off the forced recovery cleanup. If userspace sets the value to 0 then we will force the recovery cleanup immediately.

2010-01-28PCI: Always set prefetchable base/limit upper32 registersAlex Williamson
commit 59353ea30e65ab3ae181d6175e3212e1361c3787 upstream. Prior to 1f82de10 we always initialized the upper 32bits of the prefetchable memory window, regardless of the address range used. Now we only touch it for a >32bit address, which means the upper32 registers remain whatever the BIOS initialized them too. It's valid for the BIOS to set the upper32 base/limit to 0xffffffff/0x00000000, which makes us program prefetchable ranges like 0xffffffffabc00000 - 0x00000000abc00000 Revert the chunk of 1f82de10 that made this conditional so we always write the upper32 registers and remove now unused pref_mem64 variable.
