No, it seems to be a bug in the coreutils.
I did a little playing around with strace and I suspect that it may have something to do with ext3 returning DT_LNK to the filldir routine (which gets returned through getdents64). A lot of file systems always return DT_UNKNOWN. Maybe ls is handling the DT_UNKNOWN case alright, but not the DT_LNK case. (When DT_UNKNOWN is returned, ls calls stat64() which would identify the symlink as a directory rather than a symlink.)
I guess your analysis is right. The problem is that ls only calls stat() on DT_UNKNOWN entries but it should call it on DT_LNK too.

They forgot to tell you that not every bug is a kernel bug ;) I opened a bug in bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=231916 - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
