CVE-2026-29518: re-implement the "use chroot = no" confinement after the
centos7els fix: every path operation proves its parent directory beneath
the pinned module root through /proc/self/fd and runs on it with the
*at() calls. In-module symlinks, directories the daemon uid may search
but not read, -L/-K and --link-dest=../dir keep working; xattrs, ACLs and
timestamps are confined too. Drop CVE-2026-29518-2.patch
CVE-2026-43619: chmod no longer follows a leaf symlink; CVE-2026-29518:
confined calls act on the resolved object with O_NOFOLLOW
CVE-2026-29518: anchor the receiver's basis open at the pinned working
directory and prove it beneath the module, not beneath a root resolved
by name
CVE-2026-53784, CVE-2026-53786, CVE-2026-53793: re-anchor on the
re-implemented CVE-2026-29518 confinement
