Here's a respin, with the following changes:
* change message when rejecting unknown attribute types (David Ahern)
* drop nl80211 patch - I'll apply it separately
* remove NL_VALIDATE_POLICY - we have a lot of calls to nla_parse()
that really should be without a policy as it has previously been
validated - need to find a good way to handle this later
* include the correct generic netlink change (d'oh, sorry)

netlink: make validation more configurable for future strictness

We currently have two levels of strict validation:

1) liberal (default)
- undefined (type >= max) & NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
- garbage at end of message accepted
2) strict (opt-in)
- NLA_UNSPEC attributes accepted
- attribute length >= expected accepted

Split out parsing strictness into four different options:
* TRAILING - check that there's no trailing data after parsing
attributes (in message or nested)
* MAXTYPE - reject attrs > max known type
* UNSPEC - reject attributes with NLA_UNSPEC policy entries
* STRICT_ATTRS - strictly validate attribute size

The default for future things should be *everything*.
The current *_strict() is a combination of TRAILING and MAXTYPE,
and is renamed to _deprecated_strict().
The current regular parsing has none of this, and is renamed to
*_parse_deprecated().

Additionally it allows us to selectively set one of the new flags
even on old policies. Notably, the UNSPEC flag could be useful in
this case, since it can be arranged (by filling in the policy) to
not be an incompatible userspace ABI change, but would then going
forward prevent forgetting attribute entries. Similar can apply
to the POLICY flag.

We end up with the following renames:
* nla_parse -> nla_parse_deprecated
* nla_parse_strict -> nla_parse_deprecated_strict
* nlmsg_parse -> nlmsg_parse_deprecated
* nlmsg_parse_strict -> nlmsg_parse_deprecated_strict
* nla_parse_nested -> nla_parse_nested_deprecated
* nla_validate_nested -> nla_validate_nested_deprecated

For this patch, don't actually add the strict, non-renamed versions
yet so that it breaks compile if I get it wrong.

Also, while at it, make nla_validate and nla_parse go down to a
common __nla_validate_parse() function to avoid code duplication.

Ultimately, this allows us to have very strict validation for every
new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the
next patch, while existing things will continue to work as is.

In effect then, this adds fully strict validation for any new command.

Merge branch 'nla_nest_start'

Michal Kubecek says:

====================
make nla_nest_start() add NLA_F_NESTED flag

One of the comments in recent review of the ethtool netlink series pointed
out that proposed ethnl_nest_start() helper which adds NLA_F_NESTED to
second argument of nla_nest_start() is not really specific to ethtool
netlink code. That is hard to argue with as closer inspection revealed that
exactly the same helper already exists in ipset code (except it's a macro
rather than an inline function).

Another observation was that even if NLA_F_NESTED flag was introduced in
2007, only few netlink based interfaces set it in kernel generated messages
and even many recently added APIs omit it. That is unfortunate as without
the flag, message parsers not familiar with attribute semantics cannot
recognize nested attributes and do not see message structure; this affects
e.g. wireshark dissector or mnl_nlmsg_fprintf() from libmnl.

This is why I'm suggesting to rename existing nla_nest_start() to different
name (nla_nest_start_noflag) and reintroduce nla_nest_start() as a wrapper
adding NLA_F_NESTED flag. This is implemented in first patch which is
mostly generated by spatch. Second patch drops ipset helper macros which
lose their purpose. Third patch cleans up minor coding style issues found
by checkpatch.pl in first patch.

We could leave nla_nest_start() untouched and simply add a wrapper adding
NLA_F_NESTED but that would probably preserve the state when even most new
code doesn't set the flag.

netlink: make nla_nest_start() add NLA_F_NESTED flag

Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most
netlink based interfaces (including recently added ones) are still not
setting it in kernel generated messages. Without the flag, message parsers
not aware of attribute semantics (e.g. wireshark dissector or libmnl's
mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display
the structure of their contents.

Unfortunately we cannot just add the flag everywhere as there may be
userspace applications which check nlattr::nla_type directly rather than
through a helper masking out the flags. Therefore the patch renames
nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start()
as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually
are rewritten to use nla_nest_start().

Merge branch 'classifier-no-rtnl'

Vlad Buslov says:

====================
Refactor classifier API to work with chain/classifiers without rtnl lock

Currently, all netlink protocol handlers for updating rules, actions and
qdiscs are protected with single global rtnl lock which removes any
possibility for parallelism. This patch set is a third step to remove
rtnl lock dependency from TC rules update path.

Recently, new rtnl registration flag RTNL_FLAG_DOIT_UNLOCKED was added.
Handlers registered with this flag are called without RTNL taken. End
goal is to have rule update handlers(RTM_NEWTFILTER, RTM_DELTFILTER,
etc.) to be registered with UNLOCKED flag to allow parallel execution.
However, there is no intention to completely remove or split rtnl lock
itself. This patch set addresses specific problems in implementation of
classifiers API that prevent its control path from being executed
concurrently, and completes refactoring of cls API rules update handlers
by removing rtnl lock dependency from code that handles chains and
classifiers. Rules update handlers are registered with
RTNL_FLAG_DOIT_UNLOCKED flag.

This patch set substitutes global rtnl lock dependency on rules update
path in cls API by extending its data structures with following locks:
- tcf_block with 'lock' mutex. It is used to protect block state and
life-time management fields of chains on the block (chain->refcnt,
chain->action_refcnt, chain->explicitly crated, etc.).
- tcf_chain with 'filter_chain_lock' mutex, that is used to protect list
of classifier instances attached to chain. chain0->filter_chain_lock
serializes calls to head change callbacks and allows them to rely on
filter_chain_lock for serialization instead of rtnl lock.
- tcf_proto with 'lock' spinlock that is intended to be used to
synchronize access to classifiers that support unlocked execution.

Classifiers are extended with reference counting to accommodate parallel
access by unlocked cls API. Classifier ops structure is extended with
additional 'put' function to allow reference counting of filters and
intended to be used by classifiers that implement rtnl-unlocked API.
Users of classifiers and individual filter instances are modified to
always hold reference while working with them.

Classifiers that support unlocked execution still need to know the
status of rtnl lock, so their API is extended with additional
'rtnl_held' argument that is used to indicate that caller holds rtnl
lock. Cls API propagates rtnl lock status across its helper functions
and passes it to classifier.

Changes from V3 to V4:
- Patch 1:
- Extract code that manages chain 'explicitly_created' flag into
standalone patch.
- Patch 2 - new.

Changes from V2 to V3:
- Change block->lock and chain->filter_chain_lock type to mutex. This
removes the need for async miniqp refactoring and allows calling
sleeping functions while holding the block->lock and
chain->filter_chain_lock locks.
- Previous patch 1 - async miniqp is no longer needed, remove the patch.
- Patch 1:
- Change block->lock type to mutex.
- Implement tcf_block_destroy() helper function that destroys
block->lock mutex before deallocating the block.
- Revert GFP_KERNEL->GFP_ATOMIC memory allocation flags of tcf_chain
which is no longer needed after block->lock type change.
- Patch 6:
- Change chain->filter_chain_lock type to mutex.
- Assume chain0->filter_chain_lock synchronizations instead of rtnl
lock in mini_qdisc_pair_swap() function that is called from head
change callback of ingress Qdisc. With filter_chain_lock type
changed to mutex it is now possible to call sleeping function while
holding it, so it is now used instead of async implementation from
previous versions of this patch set.
- Patch 7:
- Add local tp_next var to tcf_chain_flush() and use it to store
tp->next pointer dereferenced with rcu_dereference_protected() to
satisfy kbuild test robot.
- Reset tp pointer to NULL at the beginning of tc_new_tfilter() to
prevent its uninitialized usage in error handling code. This code
was already implemented in patch 10, but must be in patch 8 to
preserve code bisectability.
- Put parent chain in tcf_proto_destroy(). In previous version this
code was implemented in patch 1 which was removed in V3.

Changes from V1 to V2:
- Patch 1:
- Use smp_store_release() instead of xchg() for setting
miniqp->tp_head.
- Move Qdisc deallocation to tc_proto_wq ordered workqueue that is
used to destroy tcf proto instances. This is necessary to ensure
that Qdisc is destroyed after all instances of chain/proto that it
contains in order to prevent use-after-free error in
tc_chain_notify_delete().
- Cache parent net device ifindex in block to prevent use-after-free
of dev queue in tc_chain_notify_delete().
- Patch 2:
- Use lockdep_assert_held() instead of spin_is_locked() for assertion.
- Use 'free_block' argument in tcf_chain_destroy() instead of checking
block's reference count and chain_list for second time.
- Patch 7:
- Refactor tcf_chain0_head_change_cb_add() to not take block->lock and
chain0->filter_chain_lock in correct order.
- Patch 10:
- Always set 'tp_created' flag when creating tp to prevent releasing
the chain twice when tp with same priority was inserted
concurrently.
- Patch 11:
- Add additional check to prevent creation of new proto instance when
parent chain is being flushed to reduce CPU usage.
- Don't call tcf_chain_delete_empty() if tp insertion failed.
- Patch 16 - new.
- Patch 17:
- Refactor to only lock take rtnl lock once (at the beginning of rule
update handlers).
- Always release rtnl mutex in the same function that locked it.
Remove unlock code from tcf_block_release().
