SBC-4 r15 5.3 COMPARE AND WRITE command states: if the compare operation does not indicate a match, then terminate the command with CHECK CONDITION status with the sense key set to MISCOMPARE and the additional sense code set to MISCOMPARE DURING VERIFY OPERATION. In the sense data (see 4.18 and SPC-5) the offset from the start of the Data-Out Buffer to the first byte of data that was not equal shall be reported in the INFORMATION field. This change implements the missing logic to report the miscompare offset in the sense data INFORMATION field. As an optimization, byte-by-byte miscompare offset calculation is only performed after memcmp() mismatch. Link: https://lore.kernel.org/r/20201031233211.5207-5-ddiss@suse.deSigned-off-by:

cmd.bad_sector currently gets packed into the sense INFORMATION field for TCM_LOGICAL_BLOCK_{GUARD,APP_TAG,REF_TAG}_CHECK_FAILED errors, which carry an .add_sector_info flag in the sense_detail_table to ensure this. In preparation for propagating a byte offset on COMPARE AND WRITE TCM_MISCOMPARE_VERIFY error, rename cmd.bad_sector to cmd.sense_info and sense_detail.add_sector_info to sense_detail.add_sense_info so that it better reflects the sense INFORMATION field destination.

There have been several attempts to fix serious problems in the compat handling in megasas_mgmt_compat_ioctl_fw(), and it also uses the compat_alloc_user_space() function. Folding the compat handling into the regular ioctl function with in_compat_syscall() simplifies it a lot and avoids some of the remaining problems: - missing handling of unaligned pointers - overflowing the ioc->frame.raw array from invalid input - compat_alloc_user_space() Link: https://lore.kernel.org/r/20201030164450.1253641-3-arnd@kernel.orgReviewed-by:

It sounds unwise to let user space pass an unchecked 32-bit offset into a kernel structure in an ioctl. This is an unsigned variable, so checking the upper bound for the size of the structure it points into is sufficient to avoid data corruption, but as the pointer might also be unaligned, it has to be written carefully as well. While I stumbled over this problem by reading the code, I did not continue checking the function for further problems like it.

The use of compat_alloc_user_space() can be easily replaced by handling compat arguments in the regular handler, and this will make it work for big-endian kernels as well, which at the moment get an invalid indirect pointer argument. Calling aac_ioctl() instead of aac_compat_do_ioctl() means the compat and native code paths behave the same way again, which they stopped when the adapter health check was added only in the native function.

Add module parameter multipath_on_hba to enable/disable multi-port path topology support. By default this feature is enabled on SAS3.5 HBA device and disabled on SAS3 &SAS2.5 HBA devices. When this feature is disabled then driver uses a default PhysicalPort(PortID) number i.e. 255 instead of the PhysicalPort number provided by HBA firmware.

During HBA reset the Port ID of vSES device may change. As a result, it is necessary to refresh virtual_phy objects after reset. Each Port's vphy_list table needs to be updated after updating the HBA port table. The algorithm is as follows: - Loop over each port entry from HBA port table * Loop over each virtual phy entry from port's vphys_list table - Mark virtual phy entry as dirty by setting dirty bit in virtual phy entry's flags field - Read SASIOUnitPage0 page - Loop over each HBA Phy's Phy data from SASIOUnitPage0 * If phy's remote attached device is not SES device then continue with processing next HBA Phy's Phy data; * Read SASPhyPage0 data for this Phy number and determine whether current phy is a virtual phy or not. If it is not a virtual phy then continue with next Phy data; * Get the current phy's remote attached vSES device's SAS Address; * Loop over each port entry from HBA port table - If Port's vphys_mask field is zero then continue with next Port entry, - Loop over each virtual phy entry from Port's vphy_list table - If the current phy's remote SAS Address is different from virtual phy entry's SAS Address then continue with next virtual phy entry, - Set bit corresponding to current phy number in virtual phy entry's phy_mask field, - Get the HBA port table's Port entry corresponding to Phy data's 'Port' value, * If there is no Port entry corresponding to Phy data's 'Port' value in HBA port table then create a new port entry and add it to HBA port table. - If this retrieved Port entry is the same as the current Port entry then don't do anything, just clear the dirty bit from virtual phy entry's flag field and continue with processing next HBA Phy's Phy data. - If this retrieved Port entry is different from the current Port entry then move the current virtual phy entry from current Port's vphys_list to retrieved Port entry's vphys_list. * Clear current phy bit in current Port entry's vphys_mask and set the current phy bit in the retrieved Port entry's vphys_mask field. * Clear the dirty bit from virtual phy entry's flag field and continue with next HBA Phy's Phy data. - Delete the 'virtual phy' entries and HBA's 'Port table' entries which are still marked as 'dirty'.

Each direct attached device will have a unique Port ID, but with an exception. HBA vSES may use the same Port ID of another direct attached device Port's ID. As a result, special handling is needed for vSES. Create a virtual_phy object when a new HBA vSES device is detected and add this virtual_phy object to vphys_list of port ID's hba_port object. When the HBA vSES device is removed then remove the corresponding virtual_phy object from its parent's hba_port's vphy_list and free this virtual_vphy object. In hba_port object add vphy_mask field to hold the list of HBA phy bits which are assigned to vSES devices. Also add vphy_list list to hold list of virtual_phy objects which holds the same portID of current hba_port's portID. Also, add a hba_vphy field in _sas_phy object to determine whether this _sas_phy object belongs to vSES device or not. - Allocate a virtual_phy object whenever a virtual phy is detected while processing the SASIOUnitPage0's phy data. And this allocated virtual_phy object to corresponding PortID's hba_port's vphy_list. - When a vSES device is added to the SML then initialize the corresponding virtual_phy objects's sas_address field with vSES device's SAS Address. - Free this virtual_phy object during driver unload time and when this vSES device is removed.

In zoning topologies this SMPPassthrough command always operates on devices in one zone (default zone) even when user issues SMP command for other zone drives. Define _transport_get_port_id_by_rphy() and _transport_get_port_id_by_sas_phy() helper functions to get Physical Port number from sas_rphy & sas_phy respectively for SMPPassthrough request message so that SMP Passthrough request message is sent to intended zone device.

During host reset there is a chance that the Port number allocated by the firmware for the attached devices may change. Also, it may be possible that some HBA phy's can go down/come up after reset. As a result, the driver can't just trust the HBA Port table that it has populated before host reset as valid. Instead it has to update the HBA Port table in such a way that it shouldn't disturb the drives which are still accessible even after host reset. Use the following algorithm to update the HBA Port table during host reset: I. After host reset operation and before marking the devices as responding/non-responding, create a temporary Port table called "New Port table" by parsing each of the HBA phy's Phy data info read from SAS IOUnit Page0: a. Check whether Phy's negotiated link rate is greater than 1.5Gbps, if not go to next Phy; b. Get the SAS Address of the attached device; c. Create a new entry in the "New Port table" with SAS Address field filled with attached device's SAS Address, port number with Phy's Port number (read from SAS IOUnit Page0) and enable bit in the 'Phy mask' field corresponding to current Phy number. New entry is created only if the driver can't find an entry in the "New Port table" which matches with attached device 'SAS Address' & 'Port Number'. If it finds an entry with matches with attached device 'SAS Address' & 'Port Number' then the driver takes that matched entry and will enable current Phy number bit in the 'Phy mask' field; d. After parsing all the HBA phy's info, the driver will have complete Port table info in "New Port table". II. Mark all the existing sas_device & sas_expander device structures as 'dirty'. III. Mark each entry of the HBA Port lists as 'dirty'. IV. Take each entry from 'New Port table' one by one and check whether the entry has any corresponding matched entry (which is marked as 'dirty') in the HBA Port table or not. While looking for a corresponding matched entry, look for matched entry in the sequence from top row to bottom row listed in the following table. If you find any matched entry (according to any of the rules tabulated below) then perform the action mentioned in the 'Action' column in that matched rule. =========================================================================== |Search |SAS | Phy Mask | Port | Possibilities| Action | |every |Address | or | Number | | required | |entry |matched?| subset of| matched?| | | |in below| | phy mask | | | | |sequence| | matched? | | | | =========================================================================== | 1 |matched | matched | matched | nothing |* unmark HBA port | | | | | | changed |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- | 2 |matched | matched | not | port number |* Update port | | | | | matched | is changed |number in the | | | | | | |matched port table | | | | | | |entry | | | | | | |* unmask HBA port | | | | | | |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- | 3.a |matched | subset of| matched |some phys |* Add these new | | | | phy mask | (or) |might have |phys to current | | | | matched | not |enabled which |port in STL | | | | | matched |are previously|* Update phy mask | | | | | (but |disabled |field in HBA's port| | | | | first | |table's matched | | | | | look for| |entry, | | | | | matched | |* Update port | | | | | one) | |number in the | | | | | | |matched port | | | | | | |table entry (if | | | | | | |port number is | | | | | | |changed), | | | | | | |* Unmask HBA port | | | | | | |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- | 3.b |matched | subset of| matched |some phys |*Remove these phys | | | | phy mask | (or) |might have |from current port | | | | matched | not |disabled which|in STL | | | | | matched |are previously|* Update phy mask | | | | | (but |enabled |field in HBA's port| | | | | first | |tables's matched | | | | | look for| |entry, | | | | | matched | |*Update port number| | | | | one) | |in the matched port| | | | | | |table entry (if | | | | | | |port number is | | | | | | |changed), | | | | | | |* Unmask HBA port | | | | | | |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- | 4 |matched | not | matched |A cable |*Remove old phys & | | | | matched | (or) |attached to an|new phys to current| | | | | not |expander is |port in STL | | | | | matched |changed to |* Update phy mask | | | | | |another HBA |field in HBA's port| | | | | |port during |tables's matched | | | | | |reset |entry, | | | | | | |*Update port number| | | | | | |in the matched port| | | | | | |table entry (if | | | | | | |port number is | | | | | | |changed), | | | | | | |* Unmask HBA port | | | | | | |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- V.

In the following scsi_host_template and sas_function_template callback functions the driver does not have PhysicalPort number information to retrieve the sas_device object using SAS Address & PhysicalPort number. In these callback functions the device's rphy object is used to retrieve sas_device object for the device. .target_alloc, .get_enclosure_identifier .get_bay_identifier When a rphy (of type sas_rphy) object is allocated then its address is saved in corresponding sas_device object's rphy field. In __mpt3sas_get_sdev_by_rphy(), the driver loops over all the sas_device objects from sas_device_list list to retrieve the sas_device objects whose rphy matches the provided rphy.

Update hba_port's sas_address & phy_mask fields whenever a direct expander or sas/sata target devices are added or removed. When any direct attached device is discovered then driver: - Gets the hba_port object corresponding to device's PhysicalPort number; - Updates the hba_port's sas_address field with device's SAS Address; - Updates the hba_port's phy_mask filed with device's narrow/wide port Phy number bits; - If a sas/sata end device (not only direct-attached devices) is added then corresponding sas_device object's port variable is assigned with hba_port object's address whose port_id matches the device's PhysicalPort number. - If an expander device is added then corresponding sas_expander object's port variable is assigned with hba_port object's address whose port_id matches the expander device's PhysicalPort number. When any direct attached device is detached then driver will delete the hba_port object corresponding to device's PhysicalPort number. Whenever any HBA phy's link (of direct attached device's port) comes up then update the phy_mask field of corresponding hba_port object.

Shift the IRQ tasklet processing from the qdio layer into zfcp. This will allow for a good amount of cleanups in qdio, and provides future opportunity to improve the IRQ processing inside zfcp. We continue to use the qdio layer's internal tasklet/timer mechanism (ie. scan_threshold etc) to check for Request Queue completions. Initially we planned to check for such completions after inspecting the Response Queue - this should typically work, but there's a theoretical race where the device only presents the Request Queue completions _after_ all Response Queue processing has finished. If the Request Queue is then also _completely_ full, we could send no further IOs and thus get no interrupt that would trigger an inspection of the Request Queue. So for now stick to the old model, where we can trust that such a race would be recovered by qdio's internal timer. Code-flow wise, this establishes two levels of control: 1. The qdio layer will only deliver IRQs to the device driver if the QDIO_IRQ_DISABLED flag is cleared. zfcp manages this through qdio_start_irq() / qdio_stop_irq(). The initial state is DISABLED, and zfcp_qdio_open() schedules zfcp's IRQ tasklet once during startup to explicitly enable IRQ delivery. 2. The zfcp tasklet is initialized with tasklet_disable(), and only gets enabled once we open the qdio device. When closing the qdio device, we must disable the tasklet _before_ disabling IRQ delivery (otherwise a concurrently running tasklet could re-enable IRQ delivery after we disabled it). A final tasklet_kill() during teardown ensures that no lingering tasklet_schedule() is still accessing the tasklet structure.

Now that MIB support was registered with FDMI, the driver may receive CT requests for MIB-related commands. At this time, no command is supported. However, the driver needs to be graceful and reject the CT request. This patch adds identification of the requests as well as sending the reject response.

Created new attribute lpfc_enable_mi, which by default is enabled. Add command definition bits for SLI-4 parameters that recognize whether the adapter has MIB information support and what revision of MIB data. Using the adapter information, register vendor-specific MIB support with FDMI. The registration will be done every link up. During FDMI registration, encountered a couple of errors when reverting to FDMI rev1. Code needed to exist once reverting. Fixed these.

The driver supports arbitrarily large scatter-gather lists and the current value for max_sectors is limiting. Change max_sectors to the largest value. This was actually done prior but it only corrected one template and that template was later removed. So change the remaining 2 templates. Other areas which hard-set the sectors value should be inheriting what is in the template. Link: https://lore.kernel.org/r/20201020202719.54726-7-james.smart@broadcom.comSigned-off-by:

During code reviews duplicate code sections were found to determine the WQ Create version. The duplication was potentially overriding logic that validated page size. Link: https://lore.kernel.org/r/20201020202719.54726-6-james.smart@broadcom.comSigned-off-by:
