Current deficiencies:
1) No HMAC hash support yet.
2) Although the algs are registered as ASYNC they always run
synchronously.Signed-off-by: David S. Miller
Signed-off-by: Herbert Xu -
These are akin to the blkcipher_walk helpers.
The main differences in the async variant are:
1) Only physical walking is supported. We can't hold on to
kmap mappings across the async operation to support virtual
ablkcipher_walk operations anyways.2) Bounce buffers used for async more need to be persistent and
freed at a later point in time when the async op completes.
Therefore we maintain a list of writeback buffers and require
that the ablkcipher_walk user call the 'complete' operation
so we can copy the bounce buffers out to the real buffers and
free up the bounce buffer chunks.These interfaces will be used by the new Niagara2 crypto driver.

Extend testmgr such that it tests async hash algorithms,
and that for both sync and async hashes it tests both
->digest() and ->update()/->final() sequences.Signed-off-by: David S. Miller

These are invoked in the 'mode' range of 400 to 499.
The cost of async vs. sync for the software algorithm implementations
varies. It can be as low as 16 cycles but as much as a couple hundred.Here two runs of md5 testing, async then sync:

yield was used to wait until all references of the internal control
structure in use are dropped before it is freed. This patch implements
padata_flush_queues which actively flushes the padata percpu queues
in this case.Signed-off-by: Steffen Klassert
Signed-off-by: Herbert Xu -
padata_get_next needs to check whether the next object that
need serialization must be parallel processed by the local cpu.
This check was wrong implemented and returned always true,
so the try_again loop in padata_reorder was never taken. This
can lead to object leaks in some rare cases due to a race that
appears with the trylock in padata_reorder. The try_again loop
was not a good idea after all, because a cpu could take that
loop frequently, so we handle this with a timer instead.This patch adds a timer to handle the race that appears with
the trylock. If cpu1 queues an object to the reorder queue while
cpu2 holds the pd->lock but left the while loop in padata_reorder
already, cpu2 can't care for this object and cpu1 exits because
it can't get the lock. Usually the next cpu that takes the lock
cares for this object too. We need the timer just if this object
was the last one that arrives to the reorder queues. The timer
function sends it out in this case.Signed-off-by: Steffen Klassert

We don't check "frontend" consistently in crypto_init_spawn2(). We
check it at the start of the function but then we dereference it
unconditionally in the parameter list when we call crypto_init_spawn().I looked at the places that call crypto_init_spawn2() and "frontend" is
always a valid pointer so I removed the check for null.Signed-off-by: Dan Carpenter

According to the header file, dt3155_io.h, the 50/60 Hz configuration
is controlled by a bit in the I2C CSR2 register (bit 2). The function
dt3155_init_isr actually reads the I2C CONFIG register into the global
I2C_CSR union variable then modifies the bit. It then does a write
to the I2C CONFIG register with the global I2C_CONFIG union variable
which is not even set with a value anywhere in the driver.My guess is 50Hz operation doesn't even work as-is.
Fix this by actually reading and writing the correct register with
the correct value.Signed-off-by: H Hartley Sweeten

When detaching a port from the client side (usbip --detach 0),
the event thread, on the server side, is going to deadlock.
The "eh" server thread is getting USBIP_EH_RESET event and calls:
-> stub_device_reset() -> usb_reset_device()
the USB framework is then calling back _in the same "eh" thread_ :
-> stub_disconnect() -> usbip_stop_eh() -> wait_for_completion()
the "eh" thread is being asleep forever, waiting for its own completion.
This patch checks if "eh" is the current thread, in usbip_stop_eh().Signed-off-by: Eric Lescouet
