This change is there in order to prepare the code to avoid calling
dvb_frontend_ioctl_legacy() from FE_SET_PROPERTY.
A call to dvb_frontend_ioctl_legacy() would require to update the
DVBv3 cache without need, mangling calls for newer delivery system
without any reason.
No functional changes here.

Due to DVB-T2, several new possible values for bandwidth were added.
As the DVBv3 struct were updated to handle them, the core needs to
handle all of them, as a DVBv3 application might try to use it.

By default, initialize the frontend current delivery system with
the first one. This warrants that a DVBv3 application will be able
to tune to it, after the removal of ops->init.type filling at
the drivers.

This seems to not serve any purpose anymore, at least all frame
processing afterwards seems to be able to deal with QoS frames. So,
let's save the expensive memmove and just leave the QoS header in the
802.11 frame for further processing.

SFQ q->perturbation is used in sfq_hash() as an input to Jenkins hash.
We currently randomize this 32bit value only if a perturbation timer is
setup.
Its much better to always initialize it to defeat attackers, or else
they can predict very well what kind of packets they have to forge to
hit a particular flow.

Since commit 817fb15dfd98 (net_sched: sfq: allow divisor to be a
parameter), we can leave perturbation timer armed if a memory allocation
error aborts sfq_init().
Memory containing active struct timer_list is freed and kernel can
crash.
Call sfq_destroy() from sfq_init() to properly dismantle qdisc.

Define special location values for RX NFC that request the driver to
select the actual rule location. This allows for implementation on
devices that use hash-based filter lookup, whereas currently the API is
more suited to devices with TCAM lookup or linear search.
In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy
the structure back to user-space after insertion so that the actual
location is returned.

Fix endianness bugs reported by sparse in the RDMA core stack. Note
that these are real bugs, but don't affect any existing code to the
best of my knowledge. The mlid issue would only affect kernel users
of rdma_join_multicast which have the rdma_cm attach/detach its QP.
There are no current in tree users that do this. (rdma_join_multicast
may be used called by user space applications, which does not have
this issue.) And the pkey setting is simply returned as
informational.

This reverts commit 93b2ec0128c431148b216b8f7337c1a52131ef03.
The call to "schedule_work()" in rtc_initialize_alarm() happens too
early, and can cause oopses at bootup
Neil Brown explains why we do it:
"If you set an alarm in the future, then shutdown and boot again after
that time, then you will end up with a timer_queue node which is in
the past.
When this happens the queue gets stuck. That entry-in-the-past won't
get removed until and interrupt happens and an interrupt won't happen
because the RTC only triggers an interrupt when the alarm is "now".
So you'll find that e.g. "hwclock" will always tell you that
'select' timed out.
So we force the interrupt work to happen at the start just in case."
and has a patch that convert it to do things in-process rather than with
the worker thread, but right now it's too late to play around with this,
so we just revert the patch that caused problems for now.

This function gets a byte number (a data extent), collects all the leafs
pointing to it and walks up the trees to find all fs roots pointing to those
leafs. It also returns the list of all leafs pointing to that extent.
It does proper locking for the involved trees, can be used on busy file
systems and honors delayed refs.

Now that we may be holding back delayed refs for a limited period, we
might end up having no runnable delayed refs. Without this commit, we'd
do busy waiting in that thread until another (runnable) ref arives.
Instead, we're detecting this situation and use a waitqueue, such that
we only try to run more refs after
a) another runnable ref was added or
b) delayed refs are no longer held back
Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net>
|

When processing a delayed ref, first check if there are still old refs in
the process of being added. If so, put this ref back to the tree. To avoid
looping on this ref, choose a newer one in the next loop.
btrfs_find_ref_cluster has to take care of that.

Sequence numbers are needed to reconstruct the backrefs of a given extent to
a certain point in time. The total set of backrefs consist of the set of
backrefs recorded on disk plus the enqueued delayed refs for it that existed
at that moment.
This patch also adds a list that records all delayed refs which are
currently in the process of being added.
When walking all refs of an extent in btrfs_find_all_roots(), we freeze the
current state of delayed refs, honor anythinh up to this point and prevent
processing newer delayed refs to assert consistency.

These new callbacks notify the dlm user about lock recovery.
GFS2, and possibly others, need to be aware of when the dlm
will be doing lock recovery for a failed lockspace member.
In the past, this coordination has been done between dlm and
file system daemons in userspace, which then direct their
kernel counterparts. These callbacks allow the same
coordination directly, and more simply.

Slot numbers are assigned to nodes when they join the lockspace.
The slot number chosen is the minimum unused value starting at 1.
Once a node is assigned a slot, that slot number will not change
while the node remains a lockspace member. If the node leaves
and rejoins it can be assigned a new slot number.
A new generation number is also added to a lockspace. It is
set and incremented during each recovery along with the slot
collection/assignment.
The slot numbers will be passed to gfs2 which will use them as
journal id's.

It appears about all functions in arch/x86/lib/atomic64_cx8_32.S
are wrong in case cmpxchg8b must be restarted, because
LOCK_PREFIX macro defines a label "1" clashing with other local
labels :
1:
some_instructions
LOCK_PREFIX
cmpxchg8b (%ebp)
jne 1b / jumps to beginning of LOCK_PREFIX !
A possible fix is to use a magic label "672" in LOCK_PREFIX asm
definition, similar to the "671" one we defined in
LOCK_PREFIX_HERE.

Just like the per-CPU ones they had several
problems/shortcomings:
Only the first memory operand was mentioned in the asm()
operands, and the 2x64-bit version didn't have a memory clobber
while the 2x32-bit one did. The former allowed the compiler to
not recognize the need to re-load the data in case it had it
cached in some register, while the latter was overly
destructive.
The types of the local copies of the old and new values were
incorrect (the types of the pointed-to variables should be used
here, to make sure the respective old/new variable types are
compatible).
The __dummy/__junk variables were pointless, given that local
copies of the inputs already existed (and can hence be used for
discarded outputs).
The 32-bit variant of cmpxchg_double_local() referenced
cmpxchg16b_local().
At once also:
- change the return value type to what it really is: 'bool'
- unify 32- and 64-bit variants
- abstract out the common part of the 'normal' and 'local' variants

Turned out the ntlmv2 (default security authentication)
upgrade was harder to test than expected, and we ran
out of time to test against Apple and a few other servers
that we wanted to. Delay upgrade of default security
from ntlm to ntlmv2 (on mount) to 3.3. Still works
fine to specify it explicitly via "sec=ntlmv2" so this
should be fine.
