os.rs: fix wrong syscall number for PowerPC #589
Conversation
__NR_getrandom is 359 on PowerPC, added from torvalds/linux@7d59deb50aa v3.17-rc5. The bug was introduced from 05f23d2 3 years ago, affecting from 0.1.1 to before 0.5.0-pre.0. It has already been fixed on the 0.5 branch at 00713a6 so this is a backport.

Okay. I don't understand why there's a dependency on Rand 0.4 there, but it looks like a hot-fix for that series is the easiest option. (This also requires updating the version number and changelog.) |
