2015-11-02sg: Fix double-free when drives detach during SG_IOCalvin Owens1-1/+7
In sg_common_write(), we free the block request and return -ENODEV if the device is detached in the middle of the SG_IO ioctl(). Unfortunately, sg_finish_rem_req() also tries to free srp->rq, so we end up freeing rq->cmd in the already free rq object, and then free the object itself out from under the current user. This ends up corrupting random memory via the list_head on the rq object. The most common crash trace I saw is this: ------------[ cut here ]------------ kernel BUG at block/blk-core.c:1420!

Additionally, since sg_rq_end_io() will never be called on the object when this happens, we need to free memory backing ->cmd if it isn't embedded in the object itself.

2015-11-02pm80xx: avoid a panic if MSI(X) interrupts are disabledBenjamin Rood1-5/+11
If MSI(X) interrupts are disabled via the kernel command line (pci=nomsi), the pm8001 driver will kernel panic because it does not detect that MSI interrupts are disabled and will soldier on and attempt to configure MSI interrupts anyways. This leads to a kernel panic, most likely because a required data structure is not available down the line. Using the pci_msi_enabled() function in order to detect if MSI interrupts are enabled before configuring them resolves this issue and avoids a kernel panic when the module is loaded. Additionally, the irq_vector structure must be initialized when legacy interrupts are being used otherwise legacy interrupts will simply not function and result in another panic.

2015-11-02pm80xx: configure PHY settings based on subsystem vendor IDBenjamin Rood1-6/+20
Previuosly, all PMC Sierra 80xx controllers are assumed to be a motherboard controller, except if the subsystem vendor ID was equal to PCI_VENDOR_ID_ADAPTEC. The driver then attempts to load PHY settings from NVRAM. While this may be correct behavior for most controllers, it does not work with Adaptec and ATTO controllers since they do not store PHY settings in NVRAM and choose to use either custom PHY settings or chip defaults. Loading random values from NVRAM may cause the controllers to malfunction in this edge case.

2015-11-02SCSI: Increase REPORT_LUNS timeoutBrian King1-1/+2
This patch fixes an issue seen with an IBM 2145 (SVC) where, following an error injection test which results in paths going offline, when they came back online, the path would timeout the REPORT_LUNS issued during the scan. This timeout situation continued until retries were expired, resulting in falling back to a sequential LUN scan. Then, since the target responds with PQ=1, PDT=0 for all possible LUNs, due to the way the sequential LUN scan code works, we end up adding 512 LUNs for each target, when there is really only a small handful of LUNs that are actually present. This patch increases the timeout used on the REPORT_LUNS to 30 seconds. This patch solves the issue of 512 non existent LUNs showing up after this event.

Implemented JBOD map which will provide quick access for JBOD path and also provide sequence number. This will help hardware to fail command to the FW in case of any sequence mismatch. Fast Path I/O for JBOD will refer JBOD map (which has sequence number per JBOD device) instead of RAID map. Previously, the driver used RAID map to get device handle for fast path I/O and this not have sequence number information. Now, driver will use JBOD map instead. As part of error handling, if JBOD map is failed/not supported by firmware, driver will continue using legacy behavior. Now there will be three IO paths for JBOD (syspd): - JBOD map with sequence number (Fast Path) - RAID map without sequence number (Fast Path) - FW path via h/w exception queue deliberately setup devhandle 0xFFFF (FW path). Relevant data structures: - Driver send new DCMD MR_DCMD_SYSTEM_PD_MAP_GET_INFO for this purpose. - struct MR_PD_CFG_SEQ- This structure represent map of single physical device. - struct MR_PD_CFG_SEQ_NUM_SYNC- This structure represent whole JBOD map in general(size, count of sysPDs configured, struct MR_PD_CFG_SEQ of syspD with 0 index). - JBOD sequence map size is: sizeof(struct MR_PD_CFG_SEQ_NUM_SYNC) + (sizeof(struct MR_PD_CFG_SEQ) * (MAX_PHYSICAL_DEVICES - 1)) which is allocated while setting up JBOD map at driver load time.

2015-10-27SCSI: fix bug in scsi_dev_info_list matchingAlan Stern1-34/+35
The "compatible" matching algorithm used for looking up old-style blacklist entries in a scsi_dev_info_list is buggy. The core of the algorithm looks like this: if (memcmp(devinfo->vendor, vendor, min(max, strlen(devinfo->vendor)))) /* not a match */ where max is the length of the device's vendor string after leading spaces have been removed but trailing spaces have not. Because of the min() computation, either entry could be a proper substring of the other and the code would still think that they match. In the case originally reported, the device's vendor and product strings were "Inateck " and " ". These matched against the following entry in the global device list: {"", "Scanner", "1.80", BLIST_NOLUN} because "" is a substring of "Inateck " and "" (the result of removing leading spaces from the device's product string) is a substring of "Scanner". The mistaken match prevented the system from scanning and finding the device's second Logical Unit. This patch fixes the problem by making two changes. First, the code for leading-space removal is hoisted out of the loop. (This means it will sometimes run unnecessarily, but since a large percentage of all lookups involve the "compatible" entries in global device list, this should be an overall improvement.) Second and more importantly, the patch removes trailing spaces and adds a check to verify that the two resulting strings are exactly the same length. This prevents matches where one entry is a proper substring of the other.
