2019-08-22crypto: vmx/xts - use fallback for ciphertext stealingArd Biesheuvel1-1/+1
For correctness and compliance with the XTS-AES specification, we are adding support for ciphertext stealing to XTS implementations, even though no use cases are known that will be enabled by this. Since the Power8 implementation already has a fallback skcipher standby for other purposes, let's use it for this purpose as well. If ciphertext stealing use cases ever become a bottleneck, we can always revisit this.

2019-08-22crypto: des - split off DES library from generic DES cipher driverArd Biesheuvel6-19/+19
Another one for the cipher museum: split off DES core processing into a separate module so other drivers (mostly for crypto accelerators) can reuse the code without pulling in the generic DES cipher itself. This will also permit the cipher interface to be made private to the crypto API itself once we move the only user in the kernel (CIFS) to this library interface.

2019-08-22random: Support freezable kthreads in add_hwgenerator_randomness()Stephen Boyd1-3/+7
The kthread calling this function is freezable after commit 03a3bb7ae631 ("hwrng: core - Freeze khwrng thread during suspend") is applied. Unfortunately, this function uses wait_event_interruptible() but doesn't check for the kthread being woken up by the fake freezer signal. When a user suspends the system, this kthread will wake up and if it fails the entropy size check it will immediately go back to sleep and not go into the freezer. Eventually, suspend will fail because the task never froze and a warning message like this may appear: PM: suspend entry (deep) Filesystems sync: 0.000 seconds Freezing user space processes ... (elapsed 0.001 seconds) done. OOM killer disabled. Freezing remaining freezable tasks ... Freezing of tasks failed after 20.003 seconds (1 tasks refusing to freeze, wq_busy=0): hwrng R running task 0 289 2 0x00000020 [<c08c64c4>] (__schedule) from [<c08c6a10>] (schedule+0x3c/0xc0) [<c08c6a10>] (schedule) from [<c05dbd8c>] (add_hwgenerator_randomness+0xb0/0x100) [<c05dbd8c>] (add_hwgenerator_randomness) from [<bf1803c8>] (hwrng_fillfn+0xc0/0x14c [rng_core]) [<bf1803c8>] (hwrng_fillfn [rng_core]) from [<c015abec>] (kthread+0x134/0x148) [<c015abec>] (kthread) from [<c01010e8>] (ret_from_fork+0x14/0x2c) Check for a freezer signal here and skip adding any randomness if the task wakes up because it was frozen. This should make the kthread freeze properly and suspend work again.

2019-08-15hwrng: core - Freeze khwrng thread during suspendStephen Boyd1-1/+4
The hwrng_fill() function can run while devices are suspending and resuming. If the hwrng is behind a bus such as i2c or SPI and that bus is suspended, the hwrng may hang the bus while attempting to add some randomness. It's been observed on ChromeOS devices with suspend-to-idle (s2idle) and an i2c based hwrng that this kthread may run and ask the hwrng device for randomness before the i2c bus has been resumed. Let's make this kthread freezable so that we don't try to touch the hwrng during suspend/resume. This ensures that we can't cause the hwrng backing driver to get into a bad state because the device is guaranteed to be resumed before the hwrng kthread is thawed.

In the process of turning caam/qi into a library, the check of MCFGR[QI] bit has been inadvertently dropped.

Similarly, ccp-dmaengine.c uses dma_get_mask(), which is defined in linux/dma-mapping.h, so include that explicitly since it requires nothing else from linux/pci.h.
