Add a flags argument to struct xattr_handler and pass it to all xattr
handler methods. This allows using the same methods for multiple
handlers, e.g. for the ACL methods which perform exactly the same action
for the access and default ACLs, just using a different underlying
attribute. With a little more groundwork it'll also allow sharing the
methods for the regular user/trusted/secure handlers in extN, ocfs2 and
jffs2 like it's already done for xfs in this patch.Also change the inode argument to the handlers to a dentry to allow
using the handlers mechnism for filesystems that require it later,
e.g. cifs.[with GFS2 bits updated by Steven Whitehouse ]

The EXPORT_SYMBOL for d_alloc_name is in fs/libfs.c but the function
is in fs/dcache.c. Move the EXPORT_SYMBOL to the line immediately
after the closing function brace line in fs/dcache.c as mentioned
in Documentation/CodingStyle.Signed-off-by: H Hartley Sweeten

procfs-style symlinks return a last_type of LAST_BIND without an actual
path string. This causes __follow_link to skip calling __vfs_follow_link
and so the dentry isn't revalidated.This is a problem when the link target sits on NFSv4 as it depends on
the VFS to revalidate the dentry before using it on an open call. Ensure
that this occurs by forcing a revalidation of the target dentry of
LAST_BIND symlinks.Signed-off-by: Jeff Layton

Limit the number of imbalance messages to once per filesystem type instead of
once per system boot. (it's actually slightly racy and could give you a
couple per fs, but this isn't a real issue)Signed-off-by: Mimi Zohar

Kill the 'update' argument of ima_path_check(), kill
dead code in ima.Current rules: ima counters are bumped at the same time
when the file switches from put_filp() fodder to fput()
one. Which happens exactly in two places - alloc_file()
and __dentry_open(). Nothing else needs to do that at
all.Signed-off-by: Al Viro

* do ima_get_count() in __dentry_open()
* stop doing that in followups
* move ima_path_check() to right after nameidata_to_filp()
* don't bump counters on itSigned-off-by: Al Viro

There are 2 groups of alloc_file() callers:
* ones that are followed by ima_counts_get
* ones giving non-regular files
So let's pull that ima_counts_get() into alloc_file();
it's a no-op in case of non-regular files.Signed-off-by: Al Viro

* take truncate logics into a helper (handle_truncate())
* rip it out of may_open()
* call it from the only caller of may_open() that might pass
O_TRUNC
* and do that after we'd finished with opening.Signed-off-by: Al Viro

ima_inode_free() has some funky #define just to confuse the crap out of me.
void ima_iint_delete(struct inode *inode)
and then things actually call ima_inode_free() and nothing calls
ima_iint_delete().Signed-off-by: Eric Paris

iints are supposed to be allocated when an inode is allocated (during
security_inode_alloc()) But we have code which will attempt to allocate
an iint during measurement calls. If we couldn't allocate the iint and we
cared, we should have died during security_inode_alloc(). Not make the
code more complex and less efficient.Signed-off-by: Eric Paris

ima_inode_alloc returns 0 and 1, but the LSM hooks expects an errno.

All users outside of fs/ of get_empty_filp() have been removed. This patch
moves the definition from the include/ directory to internal.h so no new
users crop up and removes the EXPORT_SYMBOL. I'd love to see open intents
stop using it too, but that's a problem for another day and a smarter
developer!Signed-off-by: Eric Paris

Use the sucker in other places in pathname resolution
that check MAY_EXEC for directories; lose the _lite
from name, it's equivalent of full-blown inode_permission()
for its callers (albeit still lighter, since large parts
of generic_permission() do not apply for pure MAY_EXEC).Signed-off-by: Al Viro

* if we fail in p9_conn_create(), we shouldn't leak references to struct file.
Logics in ->close() doesn't help - ->trans is already gone by the time it's
called.
* sock_create_kern() can fail.
* use of sock_map_fd() is all fscked up; I'd fixed most of that, but the
rest will have to wait for a bit more work in net/socket.c (we still are
violating the basic rule of working with descriptor table: "once the reference
is installed there, don't rely on finding it there again").Signed-off-by: Al Viro
