crypto/rand, internal/syscall/unix: add support for getrandom on NetBSD ≥ 10.0

2023-01-26T10:15:35Z

The getrandom syscall was added to NetBSD in version 10.0, see https://man.netbsd.org/NetBSD-10.0-STABLE/getrandom.2 Change-Id: I2714c1040791f7f4728be8d869058a38cbd93d4d Reviewed-on: https://go-review.googlesource.com/c/go/+/463123 Reviewed-by: Ian Lance Taylor TryBot-Result: Gopher Robot Run-TryBot: Tobias Klauser Reviewed-by: Benny Siegert

crypto/rand: properly handle large Read on windows

2022-05-05T22:44:02Z

Use the batched reader to chunk large Read calls on windows to a max of 1 << 31 - 1 bytes. This prevents an infinite loop when trying to read more than 1 << 32 -1 bytes, due to how RtlGenRandom works. This change moves the batched function from rand_unix.go to rand.go, since it is now needed for both windows and unix implementations.

crypto/rand: generate random numbers using RtlGenRandom on Windows

2020-10-27T12:00:35Z

CryptGenRandom appears to be unfavorable these days, whereas the classic RtlGenRandom is still going strong. This commit also moves the warnBlocked function into rand_unix, rather than rand, because it's now only used on unix.

all: make copyright headers consistent with one space after period

2016-03-01T23:34:33Z

This is a subset of https://golang.org/cl/20022 with only the copyright header lines, so the next CL will be smaller and more reviewable. Go policy has been single space after periods in comments for some time. The copyright header template at: https://golang.org/doc/contribute.html#copyright also uses a single space. Make them all consistent.

crypto/rand: use the getentropy syscall on OpenBSD

2016-02-26T19:58:09Z

Go already supports Linux's getrandom, which is a slightly modified version of getentropy. getentropy was added in OpenBSD 5.6. All supported versions of OpenBSD include it so, unlike with Linux and getrandom, we don't need to test for its presence. Fixes #13785.
