o Brown paperbag bug - ax25_findbyuid() was always returning a NULL pointer
as the result. Breaks ROSE completly and AX.25 if UID policy set to deny.o While the list structure of AX.25's UID to callsign mapping table was
properly protected by a spinlock, it's elements were not refcounted
resulting in a race between removal and usage of an element.Signed-off-by: Ralf Baechle DL5RB

The socket flag cleanups that went into 2.6.12-rc1 are basically oring
the flags of an old socket into the socket just being created.
Unfortunately that one was just initialized by sock_init_data(), so already
has SOCK_ZAPPED set. As the result zapped sockets are created and all
incoming connection will fail due to this bug which again was carefully
replicated to at least AX.25, NET/ROM or ROSE.In order to keep the abstraction alive I've introduced sock_copy_flags()
to copy the socket flags from one sockets to another and used that
instead of the bitwise copy thing. Anyway, the idea here has probably
been to copy all flags, so sock_copy_flags() should be the right thing.
With this the ham radio protocols are usable again, so I hope this will
make it into 2.6.13.Signed-off-by: Ralf Baechle DL5RB

This bug could cause oopses and page state corruption, because ncpfs
used the generic page-cache symlink handlign functions. But those
functions only work if the page cache is guaranteed to be "stable", ie a
page that was installed when the symlink walk was started has to still
be installed in the page cache at the end of the walk.We could have fixed ncpfs to not use the generic helper routines, but it
is in many ways much cleaner to instead improve on the symlink walking
helper routines so that they don't require that absolute stability.We do this by allowing "follow_link()" to return a error-pointer as a
cookie, which is fed back to the cleanup "put_link()" routine. This
also simplifies NFS symlink handling.Signed-off-by: Linus Torvalds

GCC 4.x really dislikes the games we are playing in
unaligned.c, and the cleanest way to fix this is to
move things into assembler.Noted by Al Viro.

Down the road we want to eliminate the use of the global kernel lock entirely
from the NFS client. To do this, we need to protect the fields in the
nfs_inode structure adequately. Start by serializing updates to the
"cache_validity" field.Note this change addresses an SMP hang found by njw@osdl.org, where processes
deadlock because nfs_end_data_update and nfs_revalidate_mapping update the
"cache_validity" field without proper serialization.Test plan:

Introduce atomic bitops to manipulate the bits in the nfs_inode structure's
"flags" field.Using bitops means we can use a generic wait_on_bit call instead of an ad hoc
locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from
nfs_inode at the same time.The other new flags field will continue to use bitmask and logic AND and OR.
This permits several flags to be set at the same time efficiently. The
following patch adds a spin lock to protect these flags, and this spin lock
will later cover other fields in the nfs_inode structure, amortizing the cost
of using this type of serialization.Test plan:

Certain bits in nfsi->flags can be manipulated with atomic bitops, and some
are better manipulated via logical bitmask operations.This patch splits the flags field into two. The next patch introduces atomic

Paulus suggested that we put xLparMap in its own .c file so that we can
generate a .s file to be included into head.S. This doesn't get around
the problem of having it at a fixed address, but it makes it more
palatable.It would be good if this could be included in 2.6.13 as it solves our
build problems with various versions of binutils and gcc. In
particular, it allows us to build an iSeries kernel on Debian unstable
using their biarch compiler.This has been built and booted on iSeries and built for pSeries and g5.

When the client performs an exclusive create and opens the file for writing,
a Netapp filer will first create the file using the mode 01777. It does this
since an NFSv3/v4 exclusive create cannot immediately set the mode bits.
The 01777 mode then gets put into the inode->i_mode. After the file creation
is successful, we then do a setattr to change the mode to the correct value
(as per the NFS spec).The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so
the latter retains the 01777 mode. A bit later, the VFS notices this, and calls
remove_suid(). This of course now resets the file mode to inode->i_mode & 0777.
Hey presto, the file mode on the server is now magically changed to 0777. Duh...Fixes http://bugzilla.linux-nfs.org/show_bug.cgi?id=32

Proper parentheses around arguments needed, especially as the macros use
a high-precedence cast operator on the argument. -
This adds a MOVE_SELF event to inotify. It is sent whenever the inode
you are watching is moved. We need this event so that we can catch
something like this:- app1:
watch /etc/mtab- app2:
cp /etc/mtab /tmp/mtab-work
mv /etc/mtab /etc/mtab~
mv /tmp/mtab-work /etc/mtabapp1 still thinks it's watching /etc/mtab but it's actually watching
/etc/mtab~.Signed-off-by: John McCutchan
