When testing sahara sha256 speed performance with tcrypt (mode=404) on

reported. This was traced to sahara_walk_and_recalc() resizing req->src

Now that the previous commit fixed sahara_sha_hw_links_create() to take
into account the actual request size, rather than relying on sg->length

Therefore, remove sahara_walk_and_recalc() and simplify associated logic.

In previous capability register implementation, qm irq related values

The reason for this call trace is that when the MSE is disabled, the value
of capability registers in the BAR space become invalid. This will make the
subsequent unregister process get the wrong irq vector through capability
registers and get the wrong irq number by pci_irq_vector().
So add a capability table structure to pre-store the valid value of the irq
information capability register in qm init process, avoid obtaining invalid
capability register value after the MSE is disabled.

[ Upstream commit 487caa8d5e ]
If the function validate_user_input() returns an error, the error path
attempts to unlock an unacquired mutex.
Acquire the mutex before calling validate_user_input(). This is not
strictly necessary but simplifies the code.

[ Upstream commit 6627f03c21 ]
The input argument `sla_in` is a pointer to a structure that contains
the parameters of the SLA which is being added or updated.
If this pointer is NULL, the function should return an error as
the data required for the algorithm is not available.
By mistake, the logic jumps to the error path which dereferences
the pointer.
This results in a warnings reported by the static analyzer Smatch when
executed without a database:
drivers/crypto/intel/qat/qat_common/adf_rl.c:871 add_update_sla()
error: we previously assumed 'sla_in' could be null (see line 812)
This issue was not found in internal testing as the pointer cannot be
NULL. The function add_update_sla() is only called (indirectly) by
the rate limiting sysfs interface implementation in adf_sysfs_rl.c
which ensures that the data structure is allocated and valid. This is
also proven by the fact that Smatch executed with a database does not
report such error.
Fix it by returning with error if the pointer `sla_in` is NULL.

Having multiple in-flight AIO requests results in unpredictable
output because they all share the same IV. Fix this by only allowing

[ Upstream commit a1c95dd5bc ]
When dma_map_single() fails, wa->address is supposed to be freed
by the callers of ccp_init_dm_workarea() through ccp_dm_free().
However, many of the call spots don't expect to have to call
ccp_dm_free() on failure of ccp_init_dm_workarea(), which may
lead to a memleak. Let's free wa->address in ccp_init_dm_workarea()
when dma_map_single() fails.

[ Upstream commit d71fdd0f3c ]
The qat_rl sysfs attribute group is registered within the adf_dev_start()
function, alongside other driver components.
If any of the functions preceding the group registration fails,
the adf_dev_start() function returns, and the caller, to undo the
operation, invokes adf_dev_stop() followed by adf_dev_shutdown().
However, the current flow lacks information about whether the
registration of the qat_rl attribute group was successful or not.
In cases where this condition is encountered, an error similar to
the following might be reported:
4xxx 0000:6b:00.0: Starting device qat_dev0
4xxx 0000:6b:00.0: qat_dev0 started 9 acceleration engines
4xxx 0000:6b:00.0: Failed to send init message
4xxx 0000:6b:00.0: Failed to start device qat_dev0
sysfs group 'qat_rl' not found for kobject '0000:6b:00.0'

4xxx 0000:6b:00.0: qat_dev0 stopped 9 acceleration engines
4xxx 0000:6b:00.0: Resetting device qat_dev0
To prevent attempting to remove attributes from a group that has not
been added yet, a flag named 'sysfs_added' is introduced. This flag
is set to true upon the successful registration of the attribute group.
