Hello,

I'm working for a client to generate embedded 32-bits Linux Kernel
working after y2038 issue.

I generated a 5.15 Kernel thought Buildroot with Coreutils 9.0, GCC
11.2.0, Binutils 2.37 and CFLAGS  -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64  -D_TIME_BITS=64

The Kernel pass y2038 but I found an issue with cp:
After analysis, the error occurs when trying to move an empty folder
without all user mode rights.

Here how to reproduce:

# mkdir -p test/test1 folder
# chmod u-w test/test1
# date -s "2040-04-02"
# cp -a test/* folder/
cp: setting permissions for 'folder/test1' : Value too large for defined data 
type

Note: The folder is copied before the error occurs. The copy works
fine before y2038.


The issue comes from coreutils-9.0/src/cp.c

Line 512 : if (lchmod (dir, stats.st_mode | S_IRWXU) != 0)

FYI I had a previous issue while calling lstat function from
<sys/stat.h> which is included in lib/lchmod.c. I used /usr/bin/stat
as a workaround.


Keep me in touch if you need more information.
