[PATCH] namespace.c: fix race in mark_mounts_for_expiry()
This patch fixes a race found by Ram in mark_mounts_for_expiry() in
fs/namespace.c.
The bug can only be triggered with simultaneous exiting of a process having
a private namespace, and expiry of a mount from within that namespace.
It's practically impossible to trigger, and I haven't even tried. But
still, a bug is a bug.
The race happens when put_namespace() is called by another task, while
mark_mounts_for_expiry() is between atomic_read() and get_namespace(). In
that case get_namespace() will be called on an already dead namespace with
unforeseeable results.
The solution was suggested by Al Viro, with his own words:
Instead of screwing with atomic_read() in there, why don't we
simply do the following:
a) atomic_dec_and_lock() in put_namespace()
b) __put_namespace() called without dropping lock
c) the first thing done by __put_namespace would be
struct vfsmount *root = namespace->root;
namespace->root = NULL;
spin_unlock(...);
....
umount_tree(root);
...
d) check in mark_... would be simply namespace && namespace->root.
And we are all set; no screwing around with atomic_read(), no magic
at all. Dying namespace gets NULL ->root.
All changes of ->root happen under spinlock.
If under a spinlock we see non-NULL ->mnt_namespace, it won't be
freed until we drop the lock (we will set ->mnt_namespace to NULL
under that lock before we get to freeing namespace).
If under a spinlock we see non-NULL ->mnt_namespace and
->mnt_namespace->root, we can grab a reference to namespace and be
sure that it won't go away.

[PATCH] namespace.c: fix mnt_namespace clearing
This patch clears mnt_namespace on unmount.
Not clearing mnt_namespace has two effects:
1) It is possible to attach a new mount to a detached mount,
because check_mnt() returns true.
This means, that when no other references to the detached mount
remain, it still can't be freed. This causes a resource leak,
and possibly un-removable modules.
2) If mnt_namespace is dereferenced (only in mark_mounts_for_expiry())
after the namspace has been freed, it can cause an Oops, memory
corruption, etc.
1) has been tested before and after the patch, 2) is only speculation.

First of a series of patches which add support for direct userspace access to
InfiniBand hardware -- so-called "userspace verbs." I believe these patches

These patches should incorporate all of the feedback from the discussion when
I posted an earlier version back in April (see
http://lkml.org/lkml/2005/4/4/267 for the start of the thread). In
particular, memory pinned for use by userspace is accounted for in
current->mm->vm_locked and requests to pin memory are checked against
RLIMIT_MEMLOCK.
This patch:
Modify the ib_verbs.h header file with changes required for InfiniBand
userspace verbs support. We add a few structures to keep track of userspace
context, and extend the driver API so that low-level drivers know when they're
creating resources that will be used from userspace.

[PATCH] ext3 xattr: Don't write to the in-inode xattr space of reserved inodes
We are not using the in-inode space for xattrs in reserved inodes because
mkfs.ext3 doesn't initialize it properly. For those inodes, we set
i_extra_isize to 0. Make sure that we also don't overwrite the
i_extra_isize field when writing out the inode in that case. This is for
cleanliness only, and doesn't fix an actual bug.

[PATCH] mostly_read data section
Add a new section called ".data.read_mostly" for data items that are read
frequently and rarely written to like cpumaps etc.
If these maps are placed in the .data section then these frequenly read
items may end up in cachelines with data is is frequently updated. In that
case all processors in an SMP system must needlessly reload the cachelines
again and again containing elements of those frequently used variables.
The ability to share these cachelines will allow each cpu in an SMP system
to keep local copies of those shared cachelines thereby optimizing
performance.

[PATCH] tty output lossage fix
The patch fixes a few corner cases around tty line editing with
very long input lines:
- n_tty_receive_char(): don't simply drop eol characters,
otherwise canon_data isn't increased and the reader isn't woken
up.
- n_tty_receive_room(): If there is no newline pending and the
edit buffer is full, allow only a single character to be written
(until eol is found and the line is flushed), so characters from
the next line aren't dropped.
- write_chan(): if an incomplete line was written, continue
writing until write() returns 0, otherwise it might not write
the eol character to flush the line and the writer goes to sleep
without ever being woken up.
BTW the core problem is that part of this should be handled in the
receive_buf path, but for this it has to return the number of
written characters, as the amount of written characters may not be
the same as the amount of characters going into the write buffer,
so the receive_room() usage in pty_write() is not really reliable.
Alan said:
The problem looks valid. The behaviour of 'traditional unix' appears to
be the following
If you exceed the line limit then beep and drop the character
Always allow EOL to complete a canonical line input
Always do signal/control processing if enabled

[PATCH] xtensa: remove old syscalls
xtensa is now in -rc1, with the obsolete syscalls still in there, so I
guess this about the last chance to correct the ABI. Applying the patch
obviously breaks all sorts of user space binaries and probably also
requires the appropriate changes to be made to libc.
On the other hand, if a decision is made to keep the broken interface, it
should at least be a conscious one instead of an oversight.

Replace a semaphore (winch_handler_sem) used in atomic code with a
spinlock, and reduces as needed the amount of protected code to the bare
minimum (for instance no kmalloc calls are needed).
This fixes the last problems with spinlocking (in UP mode with DEBUG
options); the semaphore, taken inside spinlocks, caused a "spin_lock was
already locked" warning, without this patch.
