2020-07-16crypto: chelsio - permit asynchronous skcipher as fallbackArd Biesheuvel
Even though the chelsio driver implements asynchronous versions of cbc(aes) and xts(aes), the fallbacks it allocates are required to be synchronous. Given that SIMD based software implementations are usually asynchronous as well, even though they rarely complete asynchronously (this typically only happens in cases where the request was made from softirq context, while SIMD was already in use in the task context that it interrupted), these implementations are disregarded, and either the generic C version or another table based version implemented in assembler is selected instead. Since falling back to synchronous AES is not only a performance issue, but potentially a security issue as well (due to the fact that table based AES is not time invariant), let's fix this, by allocating an ordinary skcipher as the fallback, and invoke it with the completion routine that was given to the outer request.

2020-07-16crypto: amlogic-gxl - default to build as moduleArd Biesheuvel
The AmLogic GXL crypto accelerator driver is built into the kernel if ARCH_MESON is set. However, given the single image policy of arm64, its defconfig enables all platforms by default, and so ARCH_MESON is usually enabled. This means that the AmLogic driver causes the arm64 defconfig build to pull in a huge chunk of the crypto stack as a builtin as well, which is undesirable, so let's make the amlogic GXL driver default to 'm' instead.

2020-07-16crypto:hisilicon/sec2 - update busy processing logicKai Ye
As before, if a SEC queue is at the 'fake busy' status, the request with a 'fake busy' flag will be sent into hardware and the sending function returns busy. After the request is finished, SEC driver's call back will identify the 'fake busy' flag, and notifies the user that hardware is not busy now by calling user's call back function. Now, a request sent into busy hardware will be cached in the SEC queue's backlog, return '-EBUSY' to user. After the request being finished, the cached requests will be processed in the call back function. to notify the corresponding user that SEC queue can process more requests.

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-07-15platform/x86: pcengines-apuv2: revert wiring up simswitch GPIO as LEDFlorian Eckert
This reverts commit 5037d4ddda31c2dbbb018109655f61054b1756dc. Explanation why this does not work: This change connects the simswap to the LED subsystem of the kernel. From my point of view, it's nonsense. If we do it this way, then this can be switched relatively easily via the LED subsystem (trigger: none/default-on) and that is dangerous! If this is used, it would be unfavorable, since there is also another trigger (trigger: heartbeat/netdev). Therefore, this simswap GPIO should remain in the GPIO subsystem and be switched via it and not be connected to the LED subsystem. To avoid the problems mentioned above. The LED subsystem is not made for this and it is not a good compromise, but rather dangerous.
