This seems to be a much needed patch indeed. I haven't applied it nor
tested it - just took a look at it. I noticed something that might need
to be fixed in the 3rd  hunk of tar.c patch:

@@ -642,8 +642,9 @@
     int fd = FH_SUPER->u.arch.fd;
     struct vfs_class *me = FH_SUPER->me;

-    if (mc_lseek (fd, begin + FH->pos, SEEK_SET) !=
-        begin + FH->pos) ERRNOR (EIO, -1);
+
+    off_t o = mc_lseek(fd, begin + FH->pos, SEEK_SET);
+    if ( o != begin + FH->pos) ERRNOR (EIO, -1);

     count = MIN(count, FH->ino->st.st_size - FH->pos);

The type of FH->pos is not off_t but long. See struct vfs_s_fh in
vfs/xdirentry.h .
