2019-08-30crytpo: caam - make use of iowrite64*_hi_lo in wr_reg64Andrey Smirnov
In order to be able to unify 64 and 32 bit implementations of wr_reg64, let's convert it to use helpers from <linux/io-64-nonatomic-hi-lo.h> first. Here are the steps of the transformation: 1. Inline wr_reg32 helpers: if (!caam_imx && caam_little_end) { if (caam_little_end) { iowrite32(data >> 32, (u32 __iomem *)(reg) + 1); iowrite32(data, (u32 __iomem *)(reg)); } else { iowrite32be(data >> 32, (u32 __iomem *)(reg) + 1); iowrite32be(data, (u32 __iomem *)(reg)); } } else { if (caam_little_end) { iowrite32(data >> 32, (u32 __iomem *)(reg)); iowrite32(data, (u32 __iomem *)(reg) + 1); } else { iowrite32be(data >> 32, (u32 __iomem *)(reg)); iowrite32be(data, (u32 __iomem *)(reg) + 1); } } 2. Transfrom the conditionals such that the check for 'caam_little_end' is at the top level: if (caam_little_end) { if (!caam_imx) { iowrite32(data >> 32, (u32 __iomem *)(reg) + 1); iowrite32(data, (u32 __iomem *)(reg)); } else { iowrite32(data >> 32, (u32 __iomem *)(reg)); iowrite32(data, (u32 __iomem *)(reg) + 1); } } else { iowrite32be(data >> 32, (u32 __iomem *)(reg)); iowrite32be(data, (u32 __iomem *)(reg) + 1); } 3. Invert the check for !caam_imx: if (caam_little_end) { if (caam_imx) { iowrite32(data >> 32, (u32 __iomem *)(reg)); iowrite32(data, (u32 __iomem *)(reg) + 1); } else { iowrite32(data >> 32, (u32 __iomem *)(reg) + 1); iowrite32(data, (u32 __iomem *)(reg)); } } else { iowrite32be(data >> 32, (u32 __iomem *)(reg)); iowrite32be(data, (u32 __iomem *)(reg) + 1); } 4. Make use of iowrite64* helpers from <linux/io-64-nonatomic-hi-lo.h> if (caam_little_end) { if (caam_imx) { iowrite32(data >> 32, (u32 __iomem *)(reg)); iowrite32(data, (u32 __iomem *)(reg) + 1); } else { iowrite64(data, reg); } } else { iowrite64be(data, reg); } No functional change intended.

In cases where the input is not a multiple of the AES block size (and the chaining mode is not CTR), it prints an error to the kernel log, which is a thing we usually try to avoid in response to situations that can be triggered by unprivileged users.

2019-08-22random: Support freezable kthreads in add_hwgenerator_randomness()Stephen Boyd
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 ...

2019-08-15hwrng: core - Freeze khwrng thread during suspendStephen Boyd
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.
