[crypto] Rework AES CTR/XTS streaming and squash heap churn (#2782)

2025-10-26T01:12:27+00:00

AES Updates: Replaced heap churn with stack scratch buffers tail handling now stays in-place, no more recursive transcode detours. CTR/XTS modes read in larger, aligned chunks and still handle odd offsets cleanly. XTS prefetches a few sectors ahead to reduce extra reads. AesCtrStorage writer now uses the pooled buffer properly one stack slab, chunk forward, bump counter, repeat. Result: less malloc noise, fewer watchdog spikes at startup (though mbedtls still sets the pace). This should make the loading speed slightly better than before. Make sure to test.

[nca] Use better tight loop allocation schemes (none at all) for AES decrypt/encrypt and force MbedTLS to use AES x86_64 instructions (#2750)

2025-10-17T03:08:51+00:00

Uses stack instead of allocating stuff haphazardly (16 bytes and 512 bytes respectively) - removes malloc() pollution and all that nasty stuff from tight loops Original work by Ribbit but edited by me. Will NOT bring a massive speedup since the main bottleneck is mbedtls itself, but may bring nice oddities to STARTUP TIMES nonetheless. AES instructions being forced wont affect CPUs without them since there is always a runtime check for them.

core: Make variable shadowing a compile-time error

2021-05-16T07:43:16+00:00

Now that we have most of core free of shadowing, we can enable the warning as an error to catch anything that may be remaining and also eliminate this class of logic bug entirely.

aes_util: Allow SetIV to be non-allocating

2020-08-03T18:29:58+00:00

In a few places, the data to be set as the IV is already within an array. We shouldn't require this data to be heap-allocated if it doesn't need to be. This allows certain callers to reduce heap churn.
