crypto: prefix module autoloading with "crypto-"

2015-01-29T14:45:11+00:00

commit 5d26a105b5a73e5635eae0629b42fa0a90e07b7b upstream.

This prefixes all crypto module loading with "crypto-" so we never run
the risk of exposing module auto-loading to userspace via a crypto API,
as demonstrated by Mathias Krause:

s390/ap_bus: use and-mask instead of a cast

2013-09-07T09:58:18+00:00

Let's get rid of another sparse false positive:

drivers/s390/crypto/ap_bus.c:416:64: warning:
  cast truncates bits from constant value (102030405060708 becomes 5060708)

So instead of using a cast let's use an and-mask.
That way sparse remains silent and one doesn't always have to check
if this is a valid warning/bug or just a false positive.

s390/zcrypt: Alias for new zcrypt device driver base module

2013-07-19T06:37:39+00:00

The zcrypt device driver has been split into base/bus module, api-module,
card modules and message type modules. The base module has been renamed
from z90crypt to ap.
A module alias (with the well-known z90crypt identifier) will be introduced
that enable users to use their existing way to load the zcrypt device driver.

s390/airq: simplify adapter interrupt code

2013-06-26T19:10:28+00:00

There are three users of adapter interrupts: AP, QDIO and PCI. Each
registers a single adapter interrupt with independent ISCs. Define
a "struct airq" with the interrupt handler, a pointer and a mask for
the local summary indicator and the ISC for the adapter interrupt
source. Convert the indicator array with its fixed number of adapter
interrupt sources per ISE to an array of hlists. This removes the
limitation to 32 adapter interrupts per ISC and allows for arbitrary
memory locations for the local summary indicator.

s390/zcrypt: ap bus rescan problem when toggle crypto adapters on/off

2013-05-02T15:10:20+00:00

The bus rescan process was called simultaneously on
every device failure. This finally leads into race
conditions (double device add/remove actions).

This patch protects the rescan area by mutual exclusion
and improves ap_config_timer handling

s390/irq: remove split irq fields from /proc/stat

2013-01-08T09:57:07+00:00

Now that irq sum accounting for /proc/stat's "intr" line works again we
have the oddity that the sum field (first field) contains only the sum
of the second (external irqs) and third field (I/O interrupts).
The reason for that is that these two fields are already sums of all other
fields. So if we would sum up everything we would count every interrupt
twice.
This is broken since the split interrupt accounting was merged two years
ago: 052ff461c8427629aee887ccc27478fc7373237c "[S390] irq: have detailed
statistics for interrupt types".
To fix this remove the split interrupt fields from /proc/stat's "intr"
line again and only have them in /proc/interrupts.

This restores the old behaviour, seems to be the only sane fix and mimics
a behaviour from other architectures where /proc/interrupts also contains
more than /proc/stat's "intr" line does.

s390/zcrypt: msgType50 (RSA-CRT) fix

2012-11-23T10:14:30+00:00

The message request handling (type50 - clear key) for RSA operations
(in CRT format) are now handled correctly with respect to the crb
format container.
