| H A D | ufs_vnops.c | diff 19388 Mon Nov 04 14:05:51 MST 1996 bde Fixed some races and misleading comments in ufs_rename(). 1. When a directory is renamed to an existing (empty) directory, it is possible for the target vnode to become the source vnode underneath you (because another process may complete the same rename). It was assumed that this can't happen, and the bogus errno EINVAL was returned. This was fairly harmless. Fix: return ENOENT instead, as if the source directory was renamed a little earlier. 2. The same metamorphosis is possible for non-directories. It was assumed that this can't happen, and the code for handling "just removing a link name" happened to be used. This would have worked except for fatal bugs in the link name removal - the link name was assumed to still be there, and a null pointer was followed. Fix: check the result of relookup(). This fixes PR 1930. Notes: (a) POSIX seems to say that removing link names shall have no effect. BSD (4.4Lite2 at least) does something reasonable instead. (b) The relookup() may find a file unrelated to the original. Removing this isn't correct. Consider 3 existing files A, B and C, and concurrent renames: AB = rename(A, B), another AB, and CA = rename("c", "a"). If rename() is atomic, then only the following results are possible: AB, AB (fails), CA: A = original C, B = original A, C = gone AB, CA, AB: A = gone, B = original C, C = gone CA, AB, AB (fails): A = gone, B = original C, C = gone but ufs_rename() can give: A,AB,CA,B (sorta): A = gone, B = original A, C = gone This usually doesn't matter, since getting into a race is usually an error. --- These fixes should be in 2.1.6 and 2.2. |
