From 1de3dbd9a0213a946151bac7017812822bd4b7ca Mon Sep 17 00:00:00 2001 From: Paulo Alcantara Date: Tue, 28 Nov 2023 16:37:19 -0300 Subject: [PATCH] smb: client: report correct st_size for SMB and NFS symlinks commit 9d63509547a940225d06d7eba1dc412befae255d upstream. We can't rely on FILE_STANDARD_INFORMATION::EndOfFile for reparse points as they will be always zero. Set it to symlink target's length as specified by POSIX. This will make stat() family of syscalls return the correct st_size for such files.
