Alan, I don't know you work, but my work designed with administration of
many users any several admistrators. I don't garantie that other admins
don't cause this problem. Therefore I have decided for patch the kernel.
If this patch will not be included with kernel, I will patch any new
version of kernel for me. Also, see next peace of namei.c:
/*
* Hardlinks are often used in delicate situations. We avoid
* security-related surprises by not following symlinks on the
* newname. We *do* follow them on the oldname. This is
* the same as Digital Unix 4.0, for example.
*
* Solaris 2.5.1 is similar, but for a laugh try linking from
* a dangling symlink. --KAB
*/
There is a security problem. And my situation is security problem *too*.
