lib:replace: Implement memset_explicit()

2025-11-11T13:46:42+00:00

The memset_s() implementation is a bit obscure, as it requires a
constraint handler to be set up. You don't really find any
implmentations out there.

With C23 memset_explicit() was added and this has been implemented
for glibc 2.43 and also in FreeBSD.

lib:replace: Implement setproctitle() based on PRCTL_MM_MAP

2025-10-22T08:03:35+00:00

This should work on Linux. It requires CAP_SYS_RESOURCE, but our daemons
run as root anyway.

libreplace: add rep_copy_reflink()

2024-08-20T05:41:32+00:00

FICLONERANGE was introduced in kernel version 4.5, so I guess we can just assume
it is present if HAVE_LINUX_IOCTL is defined.

lib/replace: let DISABLE_OPATH also undef __NR_openat2

2022-08-15T15:03:37+00:00

The reason for DISABLE_OPATH is to simulate a non-linux
system, so we should not use openat2() either.
