If an array is started degraded, and then the missing device
is found it can be re-added and a minimal bitmap-based recovery
will bring it fully up-to-date.
If the array is read-only a recovery would not be allowed.
But also if the array is read-only and the missing device was
present very recently, then there could be no need for any
recovery at all, so we simply include the device in the read-only
array without any recovery.
However... if the missing device was removed a little longer ago
it could be missing some updates, but if a bitmap is present it will
be conditionally accepted pending a bitmap-based update. We don't
currently detect this case properly and will include that old
device into the read-only array with no recovery even though it really
needs a recovery.
This patch keeps track of whether a bitmap-based-recovery is really
needed or not in the new Bitmap_sync rdev flag. If that is set,
then the device will not be added to a read-only array.

commit e875ecea266a543e643b19e44cf472f1412708f9
md/raid10 record bad blocks as needed during recovery.
added code to the "cannot recover this block" path to record a bad
block rather than fail the whole recovery.
Unfortunately this new case was placed *after* r10bio was freed rather
than *before*, yet it still uses r10bio.
This is will crash with a null dereference.
So move the freeing of r10bio down where it is safe.

commit 6d183de4077191d1201283a9035ce57a9b05254d
md/raid5: fix newly-broken locking in get_active_stripe.
simplified a BUG_ON, but removed too much so now it sometimes fires
when it shouldn't.
When the STRIPE_EXPANDING flag is set, the stripe_head might be on a
special list while multiple stripe_heads are collected, or it might
not be on any list, even a 'free' list when the refcount is zero. As
long as STRIPE_EXPANDING is set, it will be found and added back to a
list eventually.
So both of the BUG_ONs which test for the ->lru being empty or not
need to avoid the case where STRIPE_EXPANDING is set.
The patch which broke this was marked for -stable, so this patch needs
to be applied to any branch that received 6d183de4

The new iobarrier implementation in raid1 (which keeps normal writes
and resync activity separate) counts every request what is not before
the current resync point in either next_window_requests or
current_window_requests.
It flags that the request is counted by setting ->start_next_window.
allow_barrier follows this model exactly and decrements one of the
*_window_requests if and only if ->start_next_window is set.
However wait_barrier(), which increments *_window_requests uses a
slightly different test for setting -.start_next_window (which is set
from the return value of this function).
So there is a possibility of the counts getting out of sync, and this
leads to the resync hanging.
So change wait_barrier() to return a non-zero value in exactly the
same cases that it increments *_window_requests.
But was introduced in 3.13-rc1.

If we discover a bad block when reading we split the request and
potentially read some of it from a different device.
The code path of this has two bugs in RAID10.
1/ we get a spin_lock with _irq, but unlock without _irq!!
2/ The calculation of 'sectors_handled' is wrong, as can be clearly
seen by comparison with raid1.c
This leads to at least 2 warnings and a probable crash is a RAID10
ever had known bad blocks.

commit 5d8c71f9e5fbdd95650be00294d238e27a363b5c
md: raid5 crash during degradation
Fixed a crash in an overly simplistic way which could leave
R5_WriteError or R5_MadeGood set in the stripe cache for devices
for which it is no longer relevant.
When those devices are removed and spares added the flags are still
set and can cause incorrect behaviour.

audit_syscall_exit() saves a result of regs_return_value() in intermediate
"int" variable and passes it to __audit_syscall_exit(), which expects its
second argument as a "long" value. This will result in truncating the
value returned by a system call and making a wrong audit record.
I don't know why gcc compiler doesn't complain about this, but anyway it
causes a problem at runtime on arm64 (and probably most 64-bit archs).

NETLINK_CB(skb).sk is the socket of user space process,
netlink_unicast in kauditd_send_skb wants the kernel
side socket. Since the sk_state of audit netlink socket
is not NETLINK_CONNECTED, so the netlink_getsockbyportid
doesn't return -ECONNREFUSED.
And the socket of userspace process can be released anytime,
so the audit_sock may point to invalid socket.
this patch sets the audit_sock to the kernel side audit
netlink socket.

The backlog cannot be consumed when audit_log_start is running on auditd
even if audit_log_start calls wait_for_auditd to consume it.
The situation is the deadlock because only auditd can consume the backlog.
If the other process needs to send the backlog, it can be also stopped
by the deadlock.
So, audit_log_start running on auditd should not stop.
You can see the deadlock with the following reproducer:
# auditctl -a exit,always -S all
# reboot

We do not need to hold the audit_cmd_mutex for this family of cases. The
possible exception to this is the call to audit_filter_user(), so drop the lock
immediately after. To help in fixing the race we are trying to avoid, make
sure that nothing called by audit_filter_user() calls audit_log_start(). In
particular, watch out for *_audit_rule_match().
This fix will take care of systemd and anything USING audit. It still means
that we could race with something configuring audit and auditd shutting down.

There have been reports of auditd restarts resulting in kaudit not being able
to find a newly registered auditd. It results in reports such as:
kernel: [ 2077.233573] audit: *NO* daemon at audit_pid=1614
kernel: [ 2077.234712] audit: audit_lost=97 audit_rate_limit=0 audit_backlog_limit=320
kernel: [ 2077.234718] audit: auditd disappeared
(previously mis-spelled "dissapeared")
One possible cause is a race between the shutdown of an older auditd and a
newer one. If the newer one sets the daemon pid to itself in kauditd before
the older one has cleared the daemon pid, the newer daemon pid will be erased.
This could be caused by an automated system, or by manual intervention, but in
either case, there is no use in having the older daemon clear the daemon pid
reference since its old pid is no longer being referenced. This patch will
prevent that specific case, returning an error of EACCES.
The case for preventing a newer auditd from registering itself if there is an
existing auditd is a more difficult case that is beyond the scope of this
patch.

The default audit_backlog_limit is 64. This was a reasonable limit at one time.
systemd causes so much audit queue activity on startup that auditd doesn't
start before the backlog queue has already overflowed by more than a factor of
2. On a system with audit= not set on the kernel command line, this isn't an
issue since that history isn't kept for auditd when it is available. On a
system with audit=1 set on the kernel command line, kaudit tries to keep that
history until auditd is able to drain the queue.
This default can be changed by the "-b" option in audit.rules once the system
has booted, but won't help with lost messages on boot.
One way to solve this would be to increase the default backlog queue size to
avoid losing any messages before auditd is able to consume them. This would
be overkill to the embedded community and insufficient for some servers.
Another way to solve it might be to add a kconfig option to set the default
based on the system type. An embedded system would get the current (or
smaller) default, while Workstations might get more than now and servers might
get more.
None of these solutions helps if a system's compiled default is too small to
see the lost messages without compiling a new kernel.
This patch adds a kernel set-up parameter (audit already has one to
enable/disable it) "audit_backlog_limit=<n>" that overrides the default to
allow the system administrator to set the backlog limit.

thread on the wait queue. When kauditd dequeues an skb, all
of the waiting threads are waiting for the same resource, but
only one is going to get it, so there's no need to wake up
more than one waiter.

Only issue a wake_up in kauditd if the length of the skb queue is less than the
backlog limit. Otherwise, threads waiting in wait_for_auditd() will simply
wake up, discover that the queue is still too long for them to proceed, and go
back to sleep. This results in wasted context switches and machine cycles.
kauditd_thread() is the only function that removes buffers from audit_skb_queue
so we can't race. If we did, the timeout in wait_for_auditd() would expire and
the waiting thread would continue.

Normally, netlink ports use the PID of the userspace process as the port ID.
If the PID is already in use by a port, the kernel will allocate another port
ID to avoid conflict. Re-name all references to netlink ports from pid to
portid to reflect this reality and avoid confusion with actual PIDs. Ports
use the __u32 type, so re-type all portids accordingly.
