Public bug reported:
A regression to sshd running in a chroot exists under the following
conditions:
1) sshd was built with glibc 2.34
2) sshd is running with a kernel that does not define the close_range syscall
(kernel <= 5.8)
3) /proc/self/fd does not exist in the chroot
The glibc 2.34 implementation of fallback_closefrom fails if
/proc/self/fd is not present, which is a valid sshd use case.
