* ata: Fix ZBC_OUT command block checkDamien Le Moal2018-07-021-6/+7
| | | | | | | | | | | | | | | The block (LBA) specified must not exceed the last addressable LBA, which is dev->nr_sectors - 1. So fix the correct check is "if (block >= dev->n_sectors)" and not "if (block > dev->n_sectords)". Additionally, the asc/ascq to return for an LBA that is not a zone start LBA should be ILLEGAL REQUEST, regardless if the bad LBA is out of range.

* ahci: Disable LPM on Lenovo 50 series laptops with a too old BIOSHans de Goede2018-07-022-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There have been several reports of LPM related hard freezes about once a day on multiple Lenovo 50 series models. Strange enough these reports where not disk model specific as LPM issues usually are and some users with the exact same disk + laptop where seeing them while other users where not seeing these issues. It turns out that enabling LPM triggers a firmware bug somewhere, which has been fixed in later BIOS versions. This commit adds a new ahci_broken_lpm() function and a new ATA_FLAG_NO_LPM for dealing with this. The ahci_broken_lpm() function contains DMI match info for the 4 models which are known to be affected by this and the DMI BIOS date field for known good BIOS versions. If the BIOS date is older then the one in the table LPM will be disabled and a warning will be printed. Note the BIOS dates are for known good versions, some older versions may work too, but we don't know for sure, the table is using dates from BIOS versions for which users have confirmed that upgrading to that version makes the problem go away. Unfortunately I've been unable to get hold of the reporter who reported that BIOS version 2.35 fixed the problems on the W541 for him. I've been able to verify the DMI_SYS_VENDOR and DMI_PRODUCT_VERSION from an older dmidecode, but I don't know the exact BIOS date as reported in the DMI. Lenovo keeps a changelog with dates in their release notes, but the dates there are the release dates not the build dates which are in DMI. So I've chosen to set the date to which we compare to one day past the release date of the 2.34 BIOS. I plan to fix this with a follow up commit once I've the necessary info.

Thus that first connect fully talks to the controller and obtains values that can then be used in for blk-mq setup, etc. It also means that everything about the controller is fully know before the "create controller" call returns. This has several weaknesses: - The initial create_ctrl call made by the cli will block for a long time as wire transactions are performed synchronously. This delay becomes longer if errors occur or connectivity is lost and retries need to be performed. - Code wise, it means there is a separate connect path for initial controller connect vs the (same) steps used in the reconnect path. - And as there's separate paths, it means there's separate error handling and retry logic. It also plays havoc with the NEW state (should transition out of it after successful initial connect) vs the RESETTING and CONNECTING (reconnect) states that want to be transitioned to on error. - As there's separate paths, to recover from errors and disruptions, it requires separate recovery/retry paths as well and can severely convolute the controller state. This patch reworks the fc transport to use the same connect paths for the initial connection as it uses for reconnect. This makes a single path for error recovery and handling. This patch: - Removes the driving of the initial connect and replaces it with a state transition to CONNECTING and initiating the reconnect thread. A dummy state transition of RESETTING had to be traversed as a direct transtion of NEW->CONNECTING is not allowed. Given that the controller is "new", the RESETTING transition is a simple no-op. Once in the reconnecting thread, the normal behaviors of ctrl_loss_tmo (max_retries * connect_delay) and dev_loss_tmo will apply before the controller is torn down. - Only if the state transitions couldn't be traversed and the reconnect thread not scheduled, will the controller be torn down while in create_ctrl. - The prior code used the controller state of NEW to indicate whether request queues had been initialized or not. For the admin queue, the request queue is always created, so there's no need to check a state. For IO queues, change to tracking whether a successful io request queue create has occurred (e.g. 1st successful connect). - The initial controller id is initialized to the dynamic controller id used in the initial connect message. It will be overwritten by the real controller id once the controller is connected on the wire. Signed-off-by: James Smart <james.smart@broadcom.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

The fix is to add a MODULE_LICENSE tag. Since I'm doing that, adding a description and author field also makes sense. I went by the authors listed in the comment at the top of each file, but removed Imre's Nokia email address that I assume is not valid any more, since Imre is working at Intel these days.
