Subject: [PATCH v2 00/10] Impveovements for random.h/archrandom.h
Date: Fri, 10 Jan 2020 14:54:12 +0000 [thread overview]
Message-ID: <20200110145422.49141-1-broonie@kernel.org> (raw)
This is a resend of a series from Richard Henderson last posted back in
November:
https://lore.kernel.org/linux-arm-kernel/20191106141308.30535-1-rth@twiddle.net/
Back then Borislav said they looked good and asked if he should take
them through the tip tree but things seem to have got lost since then.
Original cover letter:
During patch review for an addition of archrandom.h for arm64, it was
suggeted that the arch_random_get_* functions should be marked __must_check.
Which does sound like a good idea, since the by-reference integer output
may be uninitialized when the boolean result is false.
In addition, it turns out that arch_has_random() and arch_has_random_seed()
are not used, and not easy to support for arm64. Rather than cobble
something together that would not be testable, remove the interfaces
against some future accidental use.
In addition, I noticed a few other minor inconsistencies between the
different architectures, e.g. powerpc isn't using bool.
Change since v1:
* Remove arch_has_random, arch_has_random_seed.
Richard Henderson (10):
