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()

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.

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.

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.

Work around this instead by abstracting the string copy in a slightly

With the conversion to blk_io_poll for better interrupt latency in normal
cases, it introduced this code path, executed when I/O aborts or logouts
are seen, which attempts to allocate memory for a mailbox command to be
issued. 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.

A prior patch introduced a spin_lock_irqsave(hbalock) in the
lpfc_post_rq_buffer() routine. Call trace is seen as the hbalock is held
with interrupts disabled during a GFP_KERNEL allocation in
lpfc_sli4_nvmet_alloc().
Fix by reordering locking so that hbalock not held when calling
sli4_nvmet_alloc() (aka rqb_buf_list()).

ZBC or ZAC disks that have a limit on the number of open zones may fail
a zone open command or a write to a zone that is not already implicitly
or explicitly open if the total number of open zones is already at the
maximum allowed.
For these operations, instead of returning the generic BLK_STS_IOERR,
return BLK_STS_ZONE_OPEN_RESOURCE which is returned as -ETOOMANYREFS to
the I/O issuer, allowing the device user to act appropriately on these
relatively benign zone resource errors.
