When we have the ISS.CGIS bit set, we already know that gPTP interrupt has
happened, so an extra GIS register check at the end of ravb_ptp_interrupt()
seems superfluous. We can model the gPTP interrupt handler like all other
dedicated interrupt handlers in the driver and make it *void*.

====================
sctp: delay calls to sk_data_ready() as much as possible
1st patch is a preparation for the 2nd. The idea is to not call
->sk_data_ready() for every data chunk processed while processing
packets but only once before releasing the socket.
v2: patchset re-checked, small changelog fixes
v3: on patch 2, make use of local vars to make it more readable
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
|
|
Currently processing of multiple chunks in a single SCTP packet leads to
multiple calls to sk_data_ready, causing multiple wake up signals which
are costy and doesn't make it wake up any faster.
With this patch it will note that the wake up is pending and will do it
before leaving the state machine interpreter, latest place possible to
do it realiably and cleanly.
Note that sk_data_ready events are not dependent on asocs, unlike waking
up writers.
v2: series re-checked
v3: use local vars to cleanup the code, suggested by Jakub Sitnicki

It wastes space and gets worse as we add new flags, so convert bit-wide
flags to a bitfield.
Currently it already saves 4 bytes in sctp_sock, which are left as holes
in it for now. The whole struct needs packing, which should be done in
another patch.
Note that do_auto_asconf cannot be merged, as explained in the comment
before it.

bridge: support sending rntl info when we set attributes through sysfs/ioctl
This patchset is used to support sending rntl info to user in some places,
and ensure that whenever those attributes change internally or from sysfs,
that a netlink notification is sent out to listeners.
It also make some adjustment in bridge sysfs so that we can implement this
easily.
I've done some tests on this patchset, like:
[br_sysfs]
1. change all the attribute values of br or brif:
$ echo $value > /sys/class/net/br0/bridge/{*}
$ echo $value > /sys/class/net/br0/brif/eth1/{*}
2. meanwhile, on another terminal to observe the msg:
$ bridge monitor
[br_ioctl]
1. in bridge-utils package, do some changes in br_set, let brctl command
use ioctl to set attribute:
if ((ret = set_sysfs(path, value)) < 0) { -->
if (1) {
$ brctl set*
2. meanwhile, on another terminal to observe the msg:
$ bridge monitor
This test covers all the attributes that brctl and sysfs support to set.

changed by ioctl
Now when we change the attributes of bridge or br_port by netlink,
a relevant netlink notification will be sent, but if we change them
by ioctl or sysfs, no notification will be sent.
We should ensure that whenever those attributes change internally or from
sysfs/ioctl, that a netlink notification is sent out to listeners.
Also, NetworkManager will use this in the future to listen for out-of-band
bridge master attribute updates and incorporate them into the runtime
configuration.
This patch is used for ioctl.

The original tokenized iid support implemented via f53adae4eae5 ("net: ipv6:
add tokenized interface identifier support") didn't allow for clearing a
device token as it was intended that this addressing mode was the only one
active for globally scoped IPv6 addresses. Later we relaxed that restriction
via 617fe29d45bd ("net: ipv6: only invalidate previously tokenized addresses"),
and we should also allow for clearing tokens as there's no good reason why
it shouldn't be allowed.

fix two more udp pull header issues

On udp sockets, recv cmsg IP_CMSG_CHECKSUM returns a checksum over
the packet payload. Since commit e6afc8ace6dd pulled the headers,
taking skb->data as the start of transport header is incorrect. Use
the transport header pointer.
Also, when peeking at an offset from the start of the packet, only
return a checksum from the start of the peeked data. Note that the
cmsg does not subtract a tail checkum when reading truncated data.

DSA refactoring: set 1
There has been a long running effort to refractor DSA probing to make
the switches true linux devices. Here are a small collection of
patches moving in this direction. Most have been seen before.
We take a little step forward by passing the dsa device point to the
driver, thus allowing it to perform resource allocations using the
normal mechanisms. This device structure will later be replaced by the
devices own device structure.
Future patches will add a true driver probe function, so we rename the
current probe function, cleaning up the namespace.
phys_port_mask continually confuses me, thinking it is about PHYs. But
it is actually about ports enabled to the outside world. So rename it to
enabled_port_mask.
