2015-06-22crypto: echainiv - Only hold RNG during initialisationHerbert Xu
This patch changes the RNG allocation so that we only hold a reference to the RNG during initialisation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-06-22crypto: seqiv - Add compatibility support without RNGHerbert Xu
When seqiv is used in compatibility mode, this patch allows it to function even when an RNG Is not available. It also changes the RNG allocation for the new explicit seqiv interface so that we only hold a reference to the RNG during initialisation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-06-22crypto: eseqiv - Offer normal cipher functionality without RNGHerbert Xu
The RNG may not be available during early boot, e.g., the relevant modules may not be included in the initramfs. As the RNG Is only needed for IPsec, we should not let this prevent use of ciphers without IV generators, e.g., for disk encryption. This patch postpones the RNG allocation to the init function so that one failure during early boot does not make the RNG unavailable for all subsequent users of the same cipher. More importantly, it lets the cipher live even if RNG allocation fails. Of course we no longer offer IV generation and which will fail with an error if invoked. But all other cipher capabilities will function as usual. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-06-22crypto: user - Add CRYPTO_MSG_DELRNGHerbert Xu
This patch adds a new crypto_user command that allows the admin to delete the crypto system RNG. Note that this can only be done if the RNG is currently not in use. The next time it is used a new system RNG will be allocated. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

The header file cryptouser.h only contains information that is exported to user-space. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-06-22crypto: rng - Do not free default RNG when it becomes unusedHerbert Xu
Currently we free the default RNG when its use count hits zero. This was OK when the IV generators would latch onto the RNG at instance creation time and keep it until the instance is torn down. Now that IV generators only keep the RNG reference during init time this scheme causes the default RNG to come and go at a high frequencey. This is highly undesirable as we want to keep a single RNG in use unless the admin wants it to be removed. This patch changes the scheme so that the system RNG once allocated is never removed unless a specifically requested. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-06-22crypto: skcipher - Allow givencrypt to be NULLHerbert Xu
Currently for skcipher IV generators they must provide givencrypt as that is the whole point. We are currently replacing skcipher IV generators with explicit IV generators. In order to maintain backwards compatibility, we need to allow the IV generators to still function as a normal skcipher when the RNG Is not present (e.g., in the initramfs during boot). IOW everything but givencrypt and givdecrypt will still work but those two will fail. Therefore this patch assigns a default givencrypt that simply returns an error should it be NULL.

2015-06-21x86/hpet: Use proper hpet device number for MSI allocationThomas Gleixner
hpet_assign_irq() is called with hpet_device->num as "hardware interrupt number", but hpet_device->num is initialized after the interrupt has been assigned, so it's always 0. As a consequence only the first MSI allocation succeeds, the following ones fail because the "hardware interrupt number" already exists. Move the initialization of dev->num and other fields before the call to hpet_assign_irq(), which is the ordering before the offending commit which introduced that regression.

2015-06-21crypto: nx - Check for bogus firmware propertiesHerbert Xu
The nx driver reads two crucial paramters from the firmware for each crypto algorithm, the maximum SG list length and byte limit. Unfortunately those two parameters may be bogus, or worse they may be absent altogether. When this happens the algorithms will still register successfully but will fail when used or tested. This patch adds checks to report any firmware entries which are found to be bogus, and avoid registering algorithms which have bogus parameters. A warning is also printed when an algorithm is not registered because of this as there may have been no firmware entries for it at all.

2015-06-20genirq: Remove bogus restriction in irq_move_mask_irq()Thomas Gleixner
If an interrupt is marked with the no balancing flag, we still allow setting the affinity for such an interrupt from the kernel itself, but for interrupts which move the affinity from interrupt context via irq_move_mask_irq() this runs into a check for the no balancing flag, which in turn ends up with an endless storm of stack dumps because the move pending flag is not reset. Allow the move for interrupts which have the no balancing flag set and clear the move pending bit before checking for interrupts with the per cpu flag set.

2015-06-19perf tools: Ensure thread-stack is flushedAdrian Hunter
The thread-stack represents a thread's current stack. When a thread exits there can still be many functions on the stack e.g. exit() can be called many levels deep, so all the callers will never return. To get that information output, the thread-stack must be flushed. Previously it was assumed the thread-stack would be flushed when the struct thread was deleted. With thread ref-counting it is no longer clear when that will be, if ever. So instead explicitly flush all the thread-stacks at the end of a session.
