2024-07-30util/getauxval: Ensure setting errno if not foundVivian Wang
Sometimes zero is a valid value for getauxval (e.g. AT_EXECFD). Make sure that we can distinguish between a valid zero value and a not found entry by setting errno. Assumes that getauxval from sys/auxv.h sets errno correctly.

2014-06-23qemu/osdep: Remove the need for qemu_init_auxvalRichard Henderson
Instead of getting backup auxv data from the env pointer given to main, read it from /proc/self/auxv. We can do this at any time, so we're not tied to any ordering wrt a call to qemu_init_auxval from main. Tested-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Richard Henderson <rth@twiddle.net>
