Ignore EEXIST error when setting promiscuous mode.
This fix is needed because the driver could set promiscuous mode
when it still has not cleared properly.
Promiscuous mode could be set only once, so setting it second
time will be rejected.

Avoid enabling or disabling VLAN 0 when trying to set promiscuous
VLAN mode if double VLAN mode is enabled. This fix is needed
because the driver tries to add the VLAN 0 filter twice (once for
inner and once for outer) when double VLAN mode is enabled. The
filter program is rejected by the firmware when double VLAN is
enabled, because the promiscuous filter only needs to be set once.
This issue was missed in the initial implementation of double VLAN
mode.

We're seeing a weird problem in production where we have overlapping
extent items in the extent tree. It's unclear where these are coming
from, and in debugging we realized there's no check in the tree checker
for this sort of problem. Add a check to the tree-checker to make sure
that the extents do not overlap each other.

During log replay, at add_link(), we may increment the link count of
another inode that has a reference that conflicts with a new reference
for the inode currently being processed.
During log replay, at add_link(), we may drop (unlink) a reference from
some inode in the subvolume tree if that reference conflicts with a new
reference found in the log for the inode we are currently processing.
After the unlink, If the link count has decreased from 1 to 0, then we
increment the link count to prevent the inode from being deleted if it's
evicted by an iput() call, because we may have references to add to that
inode later on (and we will fixup its link count later during log replay).
However incrementing the link count from 0 to 1 triggers a warning:
$ cat fs/inode.c
(...)
void inc_nlink(struct inode *inode)
{
if (unlikely(inode->i_nlink == 0)) {
WARN_ON(!(inode->i_state & I_LINKABLE));
atomic_long_dec(&inode->i_sb->s_remove_count);
}
(...)
The I_LINKABLE flag is only set when creating an O_TMPFILE file, so it's
never set during log replay.
Most of the time, the warning isn't triggered even if we dropped the last
reference of the conflicting inode, and this is because:
1) The conflicting inode was previously marked for fixup, through a call
to link_to_fixup_dir(), which increments the inode's link count;
2) And the last iput() on the inode has not triggered eviction of the
inode, nor was eviction triggered after the iput(). So at add_link(),
even if we unlink the last reference of the inode, its link count ends
up being 1 and not 0.
So this means that if eviction is triggered after link_to_fixup_dir() is
called, at add_link() we will read the inode back from the subvolume tree
and have it with a correct link count, matching the number of references
it has on the subvolume tree. So if when we are at add_link() the inode
has exactly one reference only, its link count is 1, and after the unlink
its link count becomes 0.
So fix this by using set_nlink() instead of inc_nlink(), as the former
accepts a transition from 0 to 1 and it's what we use in other similar
contexts (like at link_to_fixup_dir().
Also make add_inode_ref() use set_nlink() instead of inc_nlink() to
bump the link count from 0 to 1.
The warning is actually harmless, but it may scare users. Josef also ran
into it recently.

During log replay, when processing inode references, if we get an error
when looking up for an extended reference at __add_inode_ref(), we ignore
it and proceed, returning success (0) if no other error happens after the
lookup. This is obviously wrong because in case an extended reference
exists and it encodes some name not in the log, we need to unlink it,
otherwise the filesystem state will not match the state it had after the
last fsync.
So just make __add_inode_ref() return an error it gets from the extended
reference lookup.

This isn't necessarily new, it's just tricky to hit in practice. There
are two competing things going on here. With relocation we create a
snapshot of every fs tree with a reloc tree. Any extent buffers that
get initialized here are initialized with the reloc root lockdep key.
However since it is a snapshot, any blocks that are currently in cache
that originally belonged to the fs tree will have the normal tree
lockdep key set. This creates the lock dependency of
reloc tree -> normal tree
for the extent buffer locking during the first phase of the relocation
as we walk down the reloc root to relocate blocks.
However this is problematic because the final phase of the relocation is
merging the reloc root into the original fs root. This involves
searching down to any keys that exist in the original fs root and then
swapping the relocated block and the original fs root block. We have to
search down to the fs root first, and then go search the reloc root for
the block we need to replace. This creates the dependency of
normal tree -> reloc tree
which is why lockdep complains.
Additionally even if we were to fix this particular mismatch with a
different nesting for the merge case, we're still slotting in a block
that has a owner of the reloc root objectid into a normal tree, so that
block will have its lockdep key set to the tree reloc root, and create a
lockdep splat later on when we wander into that block from the fs root.
Unfortunately the only solution here is to make sure we do not set the
lockdep key to the reloc tree lockdep key normally, and then reset any
blocks we wander into from the reloc root when we're doing the merged.
This solves the problem of having mixed tree reloc keys intermixed with
normal tree keys, and then allows us to make sure in the merge case we
maintain the lock order of
normal tree -> reloc tree
We handle this by setting a bit on the reloc root when we do the search
for the block we want to relocate, and any block we search into or COW
at that point gets set to the reloc tree key. This works correctly
because we only ever COW down to the parent node, so we aren't resetting
the key for the block we're linking into the fs root.
With this patch we no longer have the lockdep splat in btrfs/187.

In btrfs_relocate_block_group(), the rc is allocated. Then
btrfs_relocate_block_group() calls
relocate_block_group()
prepare_to_relocate()
set_reloc_control()
that assigns rc to the variable fs_info->reloc_ctl. When
prepare_to_relocate() returns, it calls
btrfs_commit_transaction()
btrfs_start_dirty_block_groups()
btrfs_alloc_path()
kmem_cache_zalloc()
which may fail for example (or other errors could happen). When the
failure occurs, btrfs_relocate_block_group() detects the error and frees
rc and doesn't set fs_info->reloc_ctl to NULL. After that, in
btrfs_init_reloc_root(), rc is retrieved from fs_info->reloc_ctl and
then used, which may cause a use-after-free bug.
This possible bug can be triggered by calling btrfs_ioctl_balance()
before calling btrfs_ioctl_defrag().
To fix this possible bug, in prepare_to_relocate(), check if
btrfs_commit_transaction() fails. If the failure occurs,
unset_reloc_control() is called to set fs_info->reloc_ctl to NULL.

This test fails on current kernel releases because the flotwable path
now calls dst_check from packet path and will then remove the offload.
Test script has two purposes:
1. check that file (random content) can be sent to other netns (and vv)
2. check that the flow is offloaded (rather than handled by classic
forwarding path).
Since dst_check is in place, 2) fails because the nftables ruleset in
router namespace 1 intentionally blocks traffic under the assumption
that packets are not passed via classic path at all.
Rework this: Instead of blocking traffic, create two named counters, one
for original and one for reverse direction.
The first three test cases are handled by classic forwarding path
(path mtu discovery is disabled and packets exceed MTU).
But all other tests enable PMTUD, so the originator and responder are
expected to lower packet size and flowtable is expected to do the packet
forwarding.
For those tests, check that the packet counters (which are only
incremented for packets that are passed up to classic forward path)
are significantly lower than the file size transferred.
I've tested that the counter-checks fail as expected when the 'flow add'
statement is removed from the ruleset.

The function thermal_zone_device_is_enabled() must be called with the

As the thermal_zone_device_is_enabled() is also checked in

All the different calls inside the thermal_zone_device_update()
function take the mutex.
The previous changes move the mutex out of the different functions,
like the throttling ops. Now that the mutexes are all at the same
level in the call stack for the thermal_zone_device_update() function,
they can be moved inside this one.
That has the benefit of:
1. Simplify the code by not having a plethora of places where the lock is taken
2. Probably closes more race windows because releasing the lock from
one line to another can give the opportunity to the thermal zone to change
its state in the meantime. For example, the thermal zone can be
enabled right after checking it is disabled.

All the governors throttling ops are taking/releasing the lock at the
beginning and the end of the function.
We can move the mutex to the throttling call site instead.

The thermal zone lock is taken in the different places in the
throttling path.
At the first glance it does not hurt to move them at the beginning and
the end of the 'throttle' function. That will allow a consolidation of
the lock in the next following changes.

The should_stop_polling() function wraps the function
thermal_zone_device_is_enabled().
The monitor_thermal_zone() function checks if the thermal zone is
enabled via the should_stop_polling() function.
However, the instant after checking the thermal zone is enabled, this
one can be disabled, so even if that reduces the race window, it does
not prevent that and the monitoring can be set again with the thermal
zone disabled.
For this reason, the function should_stop_polling() is replaced by a
direct check of the thermal zone mode with the mutex locks held, that
prevents the situation described above.
As the semantic is clear with the thermal_zone_is_enabled() function,
we can remove the should_stop_polling() function and replace the check
with the former function.
While at it, reorder the checks to improve the readability of the
monitor_thermal_zone() function.
In the future, the thermal_zone_device_disable() and the
thermal_zone_device_enable() functions should unset / set the polling
timer directly instead of relying on the next
thermal_zone_device_update() call to do that. That will make a
synchronous thermal zone mode change but the locking scheme should be
double checked for that which out of the scope of this change.

The current code calls monitor_thermal_zone() inside the
handle_thermal_trip() function. But this one is called in a loop for
each trip point which means the monitoring is rearmed several times
for nothing (assuming there could be several passive and active trip
points).
Move the monitor_thermal_zone() function out of the
handle_thermal_trip() function and after the thermal trip loop, so the
timer will be disabled or rearmed one time.

Given the trip points can be set in the thermal zone structure, there
is no need of a specific OF function to do that. Move the code in the
place where it is generic, in the sysfs set_trip_temp storing
