* scsi: libsas: Inject revalidate event for root port eventJohn Garry2019-04-151-0/+7
| | | | | | | | | | | | | | | | | | According to the SAS spec, an expander device shall transmit BROADCAST (CHANGE) from at least one phy in each expander port other than the expander port that is the cause for transmitting BROADCAST (CHANGE). As such, for when the link is lost for a root PHY attached to an expander PHY, we get no broadcast event. This causes an issue for libsas, in that we will not revalidate the domain for these events. As a solution, for when a root PHY is formed or deformed from a root port, insert a broadcast event to trigger a domain revalidation.

| | | | | | | | | | | | | | | Currently the FC-NVMe driver is leverating the SCSI FC transport class to access the remote ports. Which means that all FC-NVMe remote ports will be visible to the fc transport layer, but due to missing definitions the port roles will always be 'unknown'. This patch adds the missing definitions to the fc transport class to that the port roles are correctly displayed.

* scsi: fcoe: make use of fip_mode enum completeSedat Dilek2019-02-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 1917d42d14b7 ("fcoe: use enum for fip_mode") introduces a separate enum for the fip_mode that shall be used during initialisation handling until it is passed to fcoe_ctrl_link_up to set the initial fip_state. That change was incomplete and gcc quietly converted in various places between the fip_mode and the fip_state enum values with implicit enum conversions, which fortunately cannot cause any issues in the actual code's execution. clang however warns about these implicit enum conversions in the scsi drivers. This commit consolidates the use of the two enums, guided by clang's enum-conversion warnings. This commit now completes the use of the fip_mode: It expects and uses fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up(). It also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to indicate these two enums are distinct.

* scsi: ata: Use unsigned int for cmd's type in ioctls in scsi_host_templateNathan Chancellor2019-02-082-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang warns several times in the scsi subsystem (trimmed for brevity): drivers/scsi/hpsa.c:6209:7: warning: overflow converting case value to switch condition type (2147762695 to 18446744071562347015) [-Wswitch] case CCISS_GETBUSTYPES: ^ drivers/scsi/hpsa.c:6208:7: warning: overflow converting case value to switch condition type (2147762694 to 18446744071562347014) [-Wswitch] case CCISS_GETHEARTBEAT: ^ The root cause is that the _IOC macro can generate really large numbers, which don't fit into type 'int', which is used for the cmd parameter in the ioctls in scsi_host_template. My research into how GCC and Clang are handling this at a low level didn't prove fruitful. However, looking at the rest of the kernel tree, all ioctls use an 'unsigned int' for the cmd parameter, which will fit all of the _IOC values in the scsi/ata subsystems. Make that change because none of the ioctls expect a negative value for any command, it brings the ioctls inline with the reset of the kernel, and it removes ambiguity, which is never good when dealing with compilers.

It is used like this: if (test_and_set_bit(SCMD_STATE_COMPLETE, &scmd->state)) The test_and_set_bit() has a shift built in so it's a double left shift and uses bit number 1 instead of number 0. This bug is harmless because it's done consistently and it doesn't clash with any other flags.

Now the ata host for libsas is embedded in domain_device, and the ->kref member is not initialized. Afer we add ata transport class, ata_host_get() will be called when adding transport ATA port and a warning will be triggered as below: refcount_t: increment on 0; use-after-free. WARNING: CPU: 2 PID: 103 at lib/refcount.c:153 refcount_inc+0x40/0x48 ......

If the refcount decreased to zero, the ata host will be freed. But this ata host is only part of domain_device, it cannot be freed directly. So we have to change this embedded static ata host to a dynamically allocated ata host and initialize the ->kref member. To use ata_host_get() and ata_host_put() in libsas, we need to move the declaration of these functions to the public libata.h and export them.

Another solution could be to add a length argument to scsi_execute(), but this function already takes a lot of arguments and Jens was not fond of that approach. Additionally, this moves the SCSI_SENSE_BUFFERSIZE definition into scsi_device.h, and removes a redundant include for scsi_device.h from scsi_cmnd.h.
