Introduce __iowrite64_copy. It will be used by the Myri-10G Ethernet
driver to post requests to the NIC. This driver will be submitted soon.
__iowrite64_copy copies to I/O memory in units of 64 bits when possible (on
64 bit architectures). It reverts to __iowrite32_copy on 32 bit
architectures.

Following problems are addressed:
- wrong status caused early break out of nand_wait()
- removed the bogus status check in nand_wait() which
is a relict of the abandoned support for interrupted
erase.
- status check moved to the correct place in read_oob
- oob support for syndrom based ecc with strange layouts
- use given offset in the AUTOOOB based oob operations
Partially based on a patch from Vitaly Vool <vwool@ru.mvista.com>
Thanks to Savin Zlobec <savin@epico.si> for tracking down the
status problem.

When an audit event involves changes to a directory entry, include
a PATH record for the directory itself. A few other notable changes:
- fixed audit_inode_child() hooks in fsnotify_move()
- removed unused flags arg from audit_inode()
- added audit log routines for logging a portion of a string
Here's some sample output.

In this implementation, audit registers inotify watches on the parent
directories of paths specified in audit rules. When audit's inotify
event handler is called, it updates any affected rules based on the
filesystem event. If the parent directory is renamed, removed, or its
filesystem is unmounted, audit removes all rules referencing that
inotify watch.
To keep things simple, this implementation limits location-based
auditing to the directory entries in an existing directory. Given
a path-based rule for /foo/bar/passwd, the following table applies:
passwd modified -- audit event logged
passwd replaced -- audit event logged, rules list updated
bar renamed -- rule removed
foo renamed -- untracked, meaning that the rule now applies to
the new location
Audit users typically want to have many rules referencing filesystem
objects, which can significantly impact filtering performance. This
patch also adds an inode-number-based rule hash to mitigate this
situation.
The patch is relative to the audit git tree:
http://kernel.org/git/?p=linux/kernel/git/viro/audit-current.git;a=summary
and uses the inotify kernel API:

This patch adds audit support to POSIX message queues. It applies cleanly to
the lspp.b15 branch of Al Viro's git tree. There are new auxiliary data
structures, and collection and emission routines in kernel/auditsc.c. New hooks
in ipc/mqueue.c collect arguments from the syscalls.
I tested the patch by building the examples from the POSIX MQ library tarball.
Build them -lrt, not against the old MQ library in the tarball. Here's the URL:
http://www.geocities.com/wronski12/posix_ipc/libmqueue-4.41.tar.gz
Do auditctl -a exit,always -S for mq_open, mq_timedsend, mq_timedreceive,
mq_notify, mq_getsetattr. mq_unlink has no new hooks. Please see the
corresponding userspace patch to get correct output from auditd for the new
record types.

The following patch addresses most of the issues with the IPC_SET_PERM
records as described in:
https://www.redhat.com/archives/linux-audit/2006-May/msg00010.html
and addresses the comments I received on the record field names.
To summarize, I made the following changes:
1. Changed sys_msgctl() and semctl_down() so that an IPC_SET_PERM
record is emitted in the failure case as well as the success case.
This matches the behavior in sys_shmctl(). I could simplify the
code in sys_msgctl() and semctl_down() slightly but it would mean
that in some error cases we could get an IPC_SET_PERM record
without an IPC record and that seemed odd.
2. No change to the IPC record type, given no feedback on the backward
compatibility question.
3. Removed the qbytes field from the IPC record. It wasn't being
set and when audit_ipc_obj() is called from ipcperms(), the
information isn't available. If we want the information in the IPC
record, more extensive changes will be necessary. Since it only
applies to message queues and it isn't really permission related, it
doesn't seem worth it.
4. Removed the obj field from the IPC_SET_PERM record. This means that
the kern_ipc_perm argument is no longer needed.
5. Removed the spaces and renamed the IPC_SET_PERM field names. Replaced iuid and
igid fields with ouid and ogid in the IPC record.
I tested this with the lspp.22 kernel on an x86_64 box. I believe it
applies cleanly on the latest kernel.

The following series of patches introduces a kernel API for inotify,
making it possible for kernel modules to benefit from inotify's
mechanism for watching inodes. With these patches, inotify will
maintain for each caller a list of watches (via an embedded struct
inotify_watch), where each inotify_watch is associated with a
corresponding struct inode. The caller registers an event handler and
specifies for which filesystem events their event handler should be
called per inotify_watch.

Having two or more qdisc_run's contend against each other is bad because
it can induce packet reordering if the packets have to be requeued. It
appears that this is an unintended consequence of relinquinshing the queue
lock while transmitting. That in turn is needed for devices that spend a
lot of time in their transmit routine.
There are no advantages to be had as devices with queues are inherently
single-threaded (the loopback device is not but then it doesn't have a
queue).
Even if you were to add a queue to a parallel virtual device (e.g., bolt
a tbf filter in front of an ipip tunnel device), you would still want to
process the queue in sequence to ensure that the packets are ordered
correctly.
The solution here is to steal a bit from net_device to prevent this.
BTW, as qdisc_restart is no longer used by anyone as a module inside the
kernel (IIRC it used to with netif_wake_queue), I have not exported the
new __qdisc_run function.

Patch from Andrew Victor
This patch includes a number of updates to the AT91RM9200 serial driver.
Changes include:
1. Conversion to a platform_driver. [Ivan Kokshaysky]
2. Replaced all references to AT91RM9200 with AT91. This driver can now
also be used for the AT91SAM9216.
3. Allow TIOCM_LOOP to configure local loopback mode.
4. Cleaned up the 'read_status_mask' usage and interrupt handler code.
[Chip Coldwell]
5. Suspend/resume support. [David Brownell]
There are a few 'unused variable' warning when compiling this - I
removed the new DMA support to keep this first patch simpler.

The current stack treats NETIF_F_HW_CSUM and NETIF_F_NO_CSUM
identically so we test for them in quite a few places. For the sake
of brevity, I'm adding the macro NETIF_F_GEN_CSUM for these two. We
also test the disjunct of NETIF_F_IP_CSUM and the other two in various
places, for that purpose I've added NETIF_F_ALL_CSUM.

The linearisation operation doesn't need to be super-optimised. So we can
replace __skb_linearize with __pskb_pull_tail which does the same thing but
is more general.
Also, most users of skb_linearize end up testing whether the skb is linear
or not so it helps to make skb_linearize do just that.
Some callers of skb_linearize also use it to copy cloned data, so it's
useful to have a new function skb_linearize_cow to copy the data if it's
either non-linear or cloned.
Last but not least, I've removed the gfp argument since nobody uses it
anymore. If it's ever needed we can easily add it back.

Various drivers use xmit_lock internally to synchronise with their
transmission routines. They do so without setting xmit_lock_owner.
This is fine as long as netpoll is not in use.
With netpoll it is possible for deadlocks to occur if xmit_lock_owner
isn't set. This is because if a printk occurs while xmit_lock is held
and xmit_lock_owner is not set can cause netpoll to attempt to take
xmit_lock recursively.
While it is possible to resolve this by getting netpoll to use
trylock, it is suboptimal because netpoll's sole objective is to
maximise the chance of getting the printk out on the wire. So
delaying or dropping the message is to be avoided as much as possible.
So the only alternative is to always set xmit_lock_owner. The
following patch does this by introducing the netif_tx_lock family of
functions that take care of setting/unsetting xmit_lock_owner.
I renamed xmit_lock to _xmit_lock to indicate that it should not be
used directly. I didn't provide irq versions of the netif_tx_lock
functions since xmit_lock is meant to be a BH-disabling lock.
This is pretty much a straight text substitution except for a small
bug fix in winbond. It currently uses
netif_stop_queue/spin_unlock_wait to stop transmission. This is
unsafe as an IRQ can potentially wake up the queue. So it is safer to
use netif_tx_disable.
The hamradio bits used spin_lock_irq but it is unnecessary as
xmit_lock must never be taken in an IRQ handler.

Add a new xtables target, CONNSECMARK, which is used to specify rules

is all it needs to do.
A typical scenario would be to apply a security mark to a 'new' packet
with SECMARK, then copy that to its conntrack via CONNMARK, and then
restore the security mark from the connection to established and
related packets on that connection.

Add a secmark field to IP and NF conntracks, so that security markings
on packets can be copied to their associated connections, and also
copied back to packets as required. This is similar to the network
mark field currently used with conntrack, although it is intended for
enforcement of security policy rather than network policy.

Add a SECMARK target to xtables, allowing the admin to apply security
marks to packets via both iptables and ip6tables.
The target currently handles SELinux security marking, but can be
extended for other purposes as needed.

Add a secmark field to the skbuff structure, to allow security subsystems to
place security markings on network packets. This is similar to the nfmark
field, except is intended for implementing security policy, rather than than
networking policy.
This patch was already acked in principle by Dave Miller.

This patch contains a fix for the previous patch that adds security
contexts to IPsec policies and security associations. In the previous
patch, no authorization (besides the check for write permissions to
SAD and SPD) is required to delete IPsec policies and security
assocations with security contexts. Thus a user authorized to change
SAD and SPD can bypass the IPsec policy authorization by simply
deleteing policies with security contexts. To fix this security hole,
an additional authorization check is added for removing security
policies and security associations with security contexts.
Note that if no security context is supplied on add or present on
policy to be deleted, the SELinux module allows the change
unconditionally. The hook is called on deletion when no context is
present, which we may want to change. At present, I left it up to the
module.
LSM changes:
The patch adds two new LSM hooks: xfrm_policy_delete and
xfrm_state_delete. The new hooks are necessary to authorize deletion
of IPsec policies that have security contexts. The existing hooks
xfrm_policy_free and xfrm_state_free lack the context to do the
authorization, so I decided to split authorization of deletion and
memory management of security data, as is typical in the LSM
interface.
Use:
The new delete hooks are checked when xfrm_policy or xfrm_state are
deleted by either the xfrm_user interface (xfrm_get_policy,
xfrm_del_sa) or the pfkey interface (pfkey_spddelete, pfkey_delete).
SELinux changes:
The new policy_delete and state_delete functions are added.
