* [PATCH] netlink: fix netlink_ack() extack race
From: Johannes Berg @ 2017-10-16 15:09 UTC (permalink / raw)
To: linux-wireless, netdev; +Cc: Johannes Berg
From: Johannes Berg <johannes.berg@intel.com>
It seems that it's possible to toggle NETLINK_F_EXT_ACK
through setsockopt() while another thread/CPU is building
a message inside netlink_ack(), which could then trigger
the WARN_ON()s I added since if it goes from being turned
off to being turned on between allocating and filling the
message, the skb could end up being too small.
Avoid this whole situation by storing the value of this
flag in a separate variable and using that throughout the
function instead.
Fixes: 2d4bc93368f5 ("netlink: extended ACK reporting")

* [PATCH net-next v2 0/7] net: dsa: master and slave helpers
From: Vivien Didelot @ 2017-10-16 15:12 UTC (permalink / raw)
To: netdev
Cc: linux-kernel, kernel, David S. Miller, Florian Fainelli,
Andrew Lunn, Vivien Didelot
This patch series adds a few helpers to DSA core for clarity and
readability but brings no functional changes.
A dsa_slave_notify helper calls the DSA notifiers when (un)registering a
slave device.
Most of the DSA slave code only needs to access the dsa_port structure,
not the dsa_slave_priv (which only contains a few PHY-specific members).
Thus a dsa_slave_to_port helper returns a dsa_port structure of a slave
device.
A dsa_slave_to_master returns the master device of a slave device.
After that the netdev member of the dsa_port structure is split into two
explicit master and slave members to avoid confusion, and a dsa_to_port
helper is added for switch drivers to get a const reference to a port.
Changes in v2:
- prefer dsa_slave_to_master instead of dsa_slave_get_master
- rename dsa_master_get_slave to dsa_master_find_slave
- pack master and slave net devices into an anonymous union
- add dsa_to_port public helper for switch drivers
- add Reviewed-by tags from Florian

When dsa_slave_create is called, the related port already has a CPU port
assigned to it, available in its cpu_dp member. Use it instead of the
unique tree cpu_dp.

Both DSA slave create and destroy functions call call_dsa_notifiers with
respectively DSA_PORT_REGISTER and DSA_PORT_UNREGISTER and the same
dsa_notifier_register_info structure.
Wrap this in a dsa_slave_notify helper so prevent cluttering these
functions.

Many part of the DSA slave code require to get the master device
assigned to a slave device. Remove dsa_master_netdev() in favor of a
dsa_slave_to_master() helper which does that.

* [PATCH net-next v2 5/7] net: dsa: rename dsa_master_get_slave

The dsa_master_get_slave is slightly confusing since the idiomatic "get"
term often suggests reference counting, in symmetry to "put".
Rename it to dsa_master_find_slave to make the look up operation clear.

* [PATCH net-next v2 6/7] net: dsa: split dsa_port's netdev member
From: Vivien Didelot @ 2017-10-16 15:12 UTC (permalink / raw)
To: netdev
Cc: linux-kernel, kernel, David S. Miller, Florian Fainelli,

In-Reply-To: <20171016151219.22023-1-vivien.didelot@savoirfairelinux.com>
The dsa_port structure has a "netdev" member, which can be used for
either the master device, or the slave device, depending on its type.
It is true that today, CPU port are not exposed to userspace, thus the
port's netdev member can be used to point to its master interface.
But it is still slightly confusing, so split it into more explicit
"master" and "slave" members inside an anonymous union.

* [PATCH net-next v2 7/7] net: dsa: add dsa_to_port helper
From: Vivien Didelot @ 2017-10-16 15:12 UTC (permalink / raw)
To: netdev
Cc: linux-kernel, kernel, David S. Miller, Florian Fainelli,
Andrew Lunn, Vivien Didelot
In-Reply-To: <20171016151219.22023-1-vivien.didelot@savoirfairelinux.com>
The dsa_port structure is part of DSA core data and must only be updated
by the later. It is OK and sometimes necessary for the DSA drivers to
access this data, but this has to be read only.
For that purpose, add a dsa_to_port() helper which returns a const
pointer to a dsa_port structure which must be used by DSA drivers from
now on instead of digging into ds->ports[] themselves.

The ci_type field of the config_item structure do not modify the fields
of the config_item_type structure it points to. And the other pointers
initialized with ci_type do not modify the fields as well.
So, make the ci_type field and the pointers initialized with ci_type
as const.
Make the struct config_item_type *type function argument of functions
config_{item/group}_init_type_name const as the argument in both the
functions is only stored in the ci_type field of a config_item structure
which is now made const.
Make the argument of configfs_register_default_group const as it is
only passed to the argument of the function config_group_init_type_name
which is now const.

Make the argument of the functions iio_sw{d/t}_group_init_type_name const
as they are only passed to the function config_group_init_type_name having
the argument as const.
Make the config_item_type structures const as they are either passed to
the functions having the argument as const or they are
stored in the const "ci_type" field of a config_item structure.

Make config_item_type structures const as they are either passed to a
function having the argument as const or stored in the const "ci_type"
field of a config_item structure.
Done using Coccinelle.

Make config_item_type structures const as they are either passed to a
function having the argument as const or used inside a if statement or
stored in the const "ci_type" field of a config_item structure.
