bug#30534: cp - Possible bugs when not preserving mode (explicit) and when copying special files

2. Non-permission bits are preserved, even when the --no-preserve=mode
option is involved.

Original file to copy: prwSrw-rw- 1 root staff 0 févr. 18 18:59 spfile
cp(1) command (run as root user): cp -r --no-preserve=mode spfile
spfile_copy

Current result:

prwsr-xr-x 1 root staff 0 févr. 18 22:05 spfile_copy

I'm not seeing this. I get 'x' rather than 's' here (and '-' with the fix)

Expected result (considering UMASK 0022 and without the first bug above):

prw-r--r-- 1 root staff 0 févr. 18 22:05 spfile_copy

thanks!
Pádraig

I'll make a new try, providing you relevant STRACE(1) output if necessary.

Thank you for your fast reaction.
