2020-11-04scsi: target: Drop sess_cmd_lock from I/O pathMike Christie1-7/+2
Drop the sess_cmd_lock by: - Removing the sess_cmd_list use from LIO core, because it's been moved to qla2xxx. - Removing sess_tearing_down check in the I/O path. Instead of using that bit and the sess_cmd_lock, we rely on the cmd_count percpu ref. To do this we switch to percpu_ref_kill_and_confirm/percpu_ref_tryget_live.

2020-11-04scsi: qla2xxx: Drop TARGET_SCF_LOOKUP_LUN_FROM_TAGMike Christie2-13/+12
Only the __qlt_24xx_handle_abts() code path does not know the LUN for an abort and it uses the TARGET_SCF_LOOKUP_LUN_FROM_TAG flag to have LIO core look it up. LIO uses target_lookup_lun_from_tag to go from cmd tag to LUN for the driver. However, qla2xxx has a tcm_qla2xxx_find_cmd_by_tag() which does almost the same thing as the LIO helper (it finds the cmd but does not return the LUN). This patch has qla2xxx use its internal helper.

2020-11-04scsi: megaraid_sas: Simplify compat_ioctl handlingArnd Bergmann2-74/+46
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.org Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Martin K.

2020-11-04scsi: megaraid_sas: Check user-provided offsetsArnd Bergmann1-5/+11
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.

2020-11-04scsi: aacraid: Improve compat_ioctl handlersArnd Bergmann2-61/+22
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.

2020-11-04scsi: mpt3sas: Handle vSES vphy object during HBA resetSreekanth Reddy1-0/+233
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'.

2020-11-04scsi: mpt3sas: Handling HBA vSES deviceSreekanth Reddy3-11/+198
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.

2020-11-04scsi: mpt3sas: Update hba_port objects after host resetSreekanth Reddy1-0/+338
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.

2020-10-29scsi: libfc: Work around -Warray-bounds warningArnd Bergmann1-11/+19
Building libfc with gcc -Warray-bounds identifies a number of cases in one file where a strncpy() is performed into a single-byte character array: In file included from include/linux/bitmap.h:9, from include/linux/cpumask.h:12, from include/linux/smp.h:13, from include/linux/lockdep.h:14, from include/linux/spinlock.h:59, from include/linux/debugobjects.h:6, from include/linux/timer.h:8, from include/scsi/libfc.h:11, from drivers/scsi/libfc/fc_elsct.c:17: In function 'strncpy', inlined from 'fc_ct_ms_fill.constprop' at drivers/scsi/libfc/fc_encode.h:235:3: include/linux/string.h:290:30: warning: '__builtin_strncpy' offset [56, 135] from the object at 'pp' is out of the bounds of referenced subobject 'value' with type '__u8[1]' {aka 'unsigned char[1]'} at offset 56 [-Warray-bounds] 290 | #define __underlying_strncpy __builtin_strncpy | ^ include/linux/string.h:300:9: note: in expansion of macro '__underlying_strncpy' 300 | return __underlying_strncpy(p, q, size); | ^~~~~~~~~~~~~~~~~~~~ This is not a bug because the 1-byte array is used as an odd way to express a variable-length data field here. I tried to convert it to a flexible-array member, but in the end could not figure out why the sizeof(struct fc_fdmi_???) are used the way they are, and how to properly convert those. Work around this instead by abstracting the string copy in a slightly higher-level function fc_ct_hdr_fill() helper that strscpy() and memset() to achieve the same result as strncpy() but does not require a zero-terminated input and does not get checked for the array overflow because gcc (so far) does not understand the behavior of strscpy().

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.

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.

This was actually done prior but it only corrected one template and that template was later removed. So change the remaining 2 templates.

The allocation is GFP_KERNEL, thus it could attempt to sleep. Fix by creating a work element that performs the event handling for the remote port. This will have the mailbox commands and other items performed in the work element, not the irq. A much better method as the "irq" routine does not stall while performing all this deep handling code. Ensure that allocation failures are handled and send LOGO on failure. Additionally, enlarge the mailbox memory pool to reduce the possibility of additional allocation in this path.
