2018-12-09	add namespace-safe version of getauxval for internal use	Rich Felker	-1/+3

2014-07-17	provide getauxval(AT_SECURE) even if it is missing from the aux vector	Rich Felker	-0/+1
	this could happen on 2.4-series linux kernels that predate AT_SECURE and possibly on other kernels that are emulating the linux syscall API but not providing AT_SECURE in the aux vector at startup. in principle applications should be checking errno anyway, but this does not really work. to be secure, the caller would have to treat ENOENT (indeterminate result) as possibly-suid and thereby disable functionality in the typical non-suid usage case. and since glibc only runs on kernels that provide AT_SECURE, applications written to the glibc getauxval API might simply assume it succeeds.
2014-04-07	add getauxval function	Rich Felker	-0/+12
	in a sense this implementation is incomplete since it doesn't provide the HWCAP_* macros for use with AT_HWCAP, which is perhaps the most important intended usage case for getauxval. they will be added at a later time.
