The linux getrandom system call returns at most 33554431 = 2^25-1 bytes per call. The existing behavior for larger reads is to report a failure, because there appears to have been an unexpected short read. In this case the system falls back to reading from "/dev/urandom". This change performs reads of 2^25 bytes or more with multiple calls to getrandom. Fixes #20877 Change-Id: I618855bdedafd86cd11219fe453af1d6fa2c88a7 Reviewed-on: https://go-review.googlesource.com/49170 Reviewed-by: Adam Langley <agl@golang.org> Run-TryBot: Adam Langley <agl@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> |
