tty: the vhangup syscall is racy

2008-10-13T16:51:41+00:00

We now have the infrastructure to sort this out but rather than teaching
the syscall tty lock rules we move the hard work into a tty helper

[PATCH] merge locate_fd() and get_unused_fd()

2008-08-01T15:25:23+00:00

	New primitive: alloc_fd(start, flags).  get_unused_fd() and
get_unused_fd_flags() become wrappers on top of it.

[PATCH] fix RLIM_NOFILE handling

2008-07-27T00:53:45+00:00

* dup2() should return -EBADF on exceeded sysctl_nr_open
* dup() should *not* return -EINVAL even if you have rlimit set to 0;
  it should get -EMFILE instead.

Check for orig_start exceeding rlimit taken to sys_fcntl().
Failing expand_files() in dup{2,3}() now gets -EMFILE remapped to -EBADF.
Consequently, remaining checks for rlimit are taken to expand_files().

[PATCH] sanitize __user_walk_fd() et.al.

2008-07-27T00:53:34+00:00

* do not pass nameidata; struct path is all the callers want.
* switch to new helpers:
	user_path_at(dfd, pathname, flags, &path)
	user_path(pathname, &path)
	user_lpath(pathname, &path)
	user_path_dir(pathname, &path)  (fail if not a directory)
  The last 3 are trivial macro wrappers for the first one.
* remove nameidata in callers.

[PATCH] preparation to __user_walk_fd cleanup

2008-07-27T00:53:32+00:00

Almost all users __user_walk_fd() and friends care only about struct path.
Get rid of the few that do not.

[patch 4/4] vfs: immutable inode checking cleanup

2008-07-27T00:53:28+00:00

Move the immutable and append-only checks from chmod, chown and utimes
into notify_change().  Checks for immutable and append-only files are
always performed by the VFS and not by the filesystem (see
permission() and may_...() in namei.c), so these belong in
notify_change(), and not in inode_change_ok().

This should be completely equivalent.

[PATCH] fix MAY_CHDIR/MAY_ACCESS/LOOKUP_ACCESS mess

2008-07-27T00:53:21+00:00

* MAY_CHDIR is redundant - it's an equivalent of MAY_ACCESS
* MAY_ACCESS on fuse should affect only the last step of pathname resolution
* fchdir() and chroot() should pass MAY_ACCESS, for the same reason why
  chdir() needs that.
* now that we pass MAY_ACCESS explicitly in all cases, LOOKUP_ACCESS can be
  removed; it has no business being in nameidata.
