Subject: privsep: allow __NR_clock_gettime32 syscall (#254)
X-Git-Tag: v10.0.4~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=52f1b730a8c25c2779fa01736575a494c3800d8c;p=thirdparty%2Fdhcpcd.git

privsep: allow __NR_clock_gettime32 syscall (#254)

musl libc doesn't have __NR_clock_gettime definition,
but has __NR_clock_gettime32. clock_gettime implementation
fallbacks to 32-bit version if 64-bit is not supported by the kernel.
