2020-02-24scsi: sr: remove references to BLK_DEV_SR_VENDOR, leave it enabledDiego Elio Pettenò45-60/+0
This kernel configuration is basically enabling/disabling sr driver quirks detection. While these quirks are for fairly rare devices (very old CD burners, and a glucometer), the additional detection of these models is a very minimal amount of code. The logic behind the quirks is always built into the sr driver. This also removes the config from all the defconfig files that are enabling this already.

2020-02-24scsi: ch: synchronize ch_probe() and ch_open()Hannes Reinecke1-4/+11
The 'ch' device node is created before the configuration is being read in, which leads to a race window when ch_open() is called before that. To avoid any races we should be taking the device mutex during ch_readconfig() and ch_init_elem(), and also during ch_open(). That ensures ch_probe is finished before ch_open() completes.

2020-02-24scsi: ch: fixup refcounting imbalance for SCSI devicesHannes Reinecke1-4/+18
The SCSI device is required to be present during ch_probe() and ch_open(). But the SCSI device itself is only checked during ch_open(), so it's anyones guess if it had been present during ch_probe(). And consequently we can't reliably detach it during ch_release(), as ch_remove() might have been called first. So initialize the changer device during ch_probe(), and take a reference to the SCSI device during both ch_probe() and ch_open().

The LIO unmap_zeroes_data device attribute is mapped to the LBPRZ flag in the READ CAPACITY(16) and Thin Provisioning VPD INQUIRY responses. The unmap_zeroes_data attribute is exposed via configfs, where any write value is correctly validated via strtobool(). However, when initialised via target_configure_unmap_from_queue() it takes the value of the device's max_write_zeroes_sectors queue limit, which is non-boolean. A non-boolean value can be read from configfs, but attempting to write the same value back results in -EINVAL, causing problems for configuration utilities such as targetcli.

2020-02-18scsi: advansys: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-02-18scsi: lpfc: add RDF registration and Link Integrity FPIN loggingJames Smart7-23/+361
This patch modifies lpfc to register for Link Integrity events via the use of an RDF ELS and to perform Link Integrity FPIN logging. Specifically, the driver was modified to: - Format and issue the RDF ELS immediately following SCR registration. This registers the ability of the driver to receive FPIN ELS. - Adds decoding of the FPIN els into the received descriptors, with logging of the Link Integrity event information. After decoding, the ELS is delivered to the scsi fc transport to be delivered to any user-space applications. - To aid in logging, simple helpers were added to create enum to name string lookup functions that utilize the initialization helpers from the fc_els.h header. - Note: base header definitions for the ELS's don't populate the descriptor payloads. As such, lpfc creates it's own version of the structures, using the base definitions (mostly headers) and additionally declaring the descriptors that will complete the population of the ELS.

The bus bandwidth voting is required to be done before the bus clocks are enabled, and the unvoting is required to be done only after the bus clocks are disabled.

2020-02-13scsi: ufs: set load before setting voltage in regulatorsAsutosh Das1-5/+5
This sequence change is required to avoid dips in voltage during boot-up. Apparently, this dip is caused because in the original sequence, the regulators are initialized in lpm mode. And then when the load is set to high, and more current is drawn, than is allowed in lpm, the dip is seen.

2020-02-13scsi: ufs: Flush exception event before suspendSayali Lokhande1-3/+18
Exception event can be raised by the device when system suspend is in progress. This will result in unclocked register access in exception event handler as clocks will be turned off during suspend. This change makes sure to flush exception event handler work in suspend before disabling clocks to avoid unclocked register access issue.

2020-02-11scsi: lpfc: Remove handler for obsolete ELS - Read Port Status (RPS)James Smart3-209/+5
There was report of an odd "Fix me..." log message, which was tracked down to the lpfc_els_rcv_rps() routine. This was in handling of a very old and obsolete ELS - Read Port Status. The RPS ELS was defined in FC-LS-1, but deprecated in FC-LS-2, and removed from all later FC-LS revisions. It was replaced by the Read Diagnostic Parameters (RDP) ELS and the Link Error Status Block descriptor. There should be no support for the RSP ELS. Remove support from driver.
