[UML]: uml-net: don't set IFF_ALLMULTI in set_multicast_list

2008-03-26T07:16:29+00:00

IFF_ALLMULTI is an indication from the network stack to the driver
to disable multicast filters, drivers should never set it directly.

Since the UML networking device doesn't have any filtering capabilites,
it doesn't the set_multicast_list function at all, it is kept so userspace
can still issue SIOCADDMULTI/SIOCDELMULTI ioctls however.

uml: fix helper_wait calls in watchdog

2008-02-24T01:12:15+00:00

In commit 1aa351a308d2c3ddb92b6cc45083fc54271d0010 ("uml: tidy helper
code") the arguments of helper_wait() were changed.  The adaptation of
harddog_user.c was forgotten, so this errors occur:

  /arch/um/drivers/harddog_user.c: In function 'start_watchdog':
  /arch/um/drivers/harddog_user.c:82: error: too many arguments to function 'helper_wait'
  /arch/um/drivers/harddog_user.c:89: error: too many arguments to function 'helper_wait'

Embed a struct path into struct nameidata instead of nd->{dentry,mnt}

2008-02-15T05:13:33+00:00

This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.

Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
   pairs
- it prepares the VFS for stacking support since it is essential to have a
  struct path in every place where the stack can be traversed
- it reduces the overall code size:

without patch series:
   text    data     bss     dec     hex filename
5321639  858418  715768 6895825  6938d1 vmlinux

with patch series:
   text    data     bss     dec     hex filename
5320026  858418  715768 6894212  693284 vmlinux

This patch:

Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

uml: port mutex conversion

2008-02-05T17:44:32+00:00

The port_sem is already used as a mutex since it's using DECLARE_MUTEX(), but
the underlying construct is still a semaphore ..  This patch switches it over
to a struct mutex.

uml: use of a public MAC is a warning, not an error

2008-02-05T17:44:31+00:00

Downgrade one of the MAC validity checks.  If it's one that could be possibly
assigned to a physical NIC, then nothing will break.  So, emit a warning in
this case, but keep the requested MAC.

uml: fix infinite mconsole loop

2008-02-05T17:44:31+00:00

This patch takes care of a problem with the stopping code.

The function inside the while condition returns 0 to signify a problem.  A
problem could be for example a bad command or a bad version of the mconsole
client.  A bad command would terminate the stopping loop and resume the
kernel.  This is a problem.

A better solution is to make the loop infinite and don't leave it until we are
explicitly told to.

uml: DEBUG_SHIRQ fixes

2008-02-05T17:44:31+00:00

A couple more DEBUG_SHIRQ fixes.

The previous mconsole blocking fix exposed the lack of O_NONBLOCK on the
mconsole socket.

Also, winch_interrupt started crashing because it is called at irq free time
and it tries to dereference tty->driver_data, which has already been set to
NULL.

I added some error cleanup in mconsole_init while I was there.

uml: remove fakehd

The fakehd switch lost its implementation at some point.  Since no one is
screaming for it, we might as well remove it.
