That way we don't have to reinstantiate another nf_hook_state
on the stack of the nf_reinject() path.
Signed-off-by: David S. Miller <davem@davemloft.net>
|
|
Instead of passing a large number of arguments down into the nf_hook()
entry points, create a structure which carries this state down through
the hook processing layers.
This makes is so that if we want to change the types or signatures of
any of these pieces of state, there are less places that need to be
changed.

Quentin caught a corner case with the generation of instruction
padding in the ALTERNATIVE_2 macro: if len(orig_insn) <
len(alt1) < len(alt2), then not enough padding gets added and
that is not good(tm) as we could overwrite the beginning of the
next instruction.
Luckily, at the time of this writing, we don't have
ALTERNATIVE_2() invocations which have that problem and even if
we did, a simple fix would be to prepend the instructions with
enough prefixes so that that corner case doesn't happen.
However, best it would be if we fixed it properly. See below for
a simple, abstracted example of what we're doing.
So what we ended up doing is, we compute the
max(len(alt1), len(alt2)) - len(orig_insn)
and feed that value to the .skip gas directive. The max() cannot
have conditionals due to gas limitations, thus the fancy integer
math.
With this patch, all ALTERNATIVE_2 sites get padded correctly;
generating obscure test cases pass too:
#define alt_max_short(a, b) ((a) ^ (((a) ^ (b)) & -(-((a) < (b)))))
#define gen_skip(orig, alt1, alt2, marker) \
.skip -((alt_max_short(alt1, alt2) - (orig)) > 0) * \
(alt_max_short(alt1, alt2) - (orig)),marker
.pushsection .text, "ax"
.globl main
main:
gen_skip(1, 2, 4, 0x09)
gen_skip(4, 1, 2, 0x10)
...
.popsection
Thanks to Quentin for catching it and double-checking the fix!

Adding this quirk allows us to avoid the noisy
"cannot get freq at ep 0x1" message in dmesg output every time

This ought to affect other Benchmark DAC1 variations using the same

Introduce data structures and code allowing "built-in" properties
to be associated with devices in such a way that they will be used
by the device_property_* API if no proper firmware node (neither DT
nor ACPI) is present for the given device.
Each property is to be represented by a property_entry structure.
An array of property_entry structures (terminated with a null
entry) can be pointed to by the properties field of struct
property_set that can be added as a firmware node to a struct
device using device_add_property_set(). That will cause the
device_property_* API to use that property_set as the source
of properties if the given device does not have a DT node or
an ACPI companion device object associated with it.

Add a secondary pointer to struct fwnode_handle so as to make it
possible for a device to have two firmware nodes associated with
it at the same time, for example, an ACPI node and a node with
a set of properties provided by platform initialization code.
In the future that will allow device property lookup to fall back
from the primary firmware node to the secondary one if the given
property is not present there to make it easier to provide defaults
for device properties used by device drivers.
Introduce two helper routines, set_primary_fwnode() and
set_secondary_fwnode() allowing callers to add a primary/secondary
firmware node to the given device in such a way that
(1) If there's only one firmware node for that device, it will be
pointed to by the device's firmware node pointer.
(2) If both the primary and secondary firmware nodes are present,
the primary one will be pointed to by the device's firmware
node pointer, while the secondary one will be pointed to by the
primary node's secondary pointer.
(3) If one of these nodes is removed (by calling one of the new
nelpers with NULL as the second argument), the other one will
be preserved.
Make ACPI use set_primary_fwnode() for attaching its firmware nodes
to devices.

With this patch kernel will be able to handle setup request. This is
needed if we would like to handle control mesages with extension
headers. User space will be only resposible for reading setup data and
checking if scenario is conformance to specification (dst and src device
bnep role). In case of new user space, setup data must be leaved(peek
msg) on queue. New bnep session will be responsible for handling this
data.

Handling extended headers of control frames is required BNEP

This is needed if user space wants to know supported bnep features
by kernel, e.g. if kernel supports sending response to bnep setup
control message. By now there is no possibility to know supported
features by kernel in case of bnep. Ioctls allows only to add connection,
delete connection, get connection list, get connection info. Adding
connection if it's possible (establishing network device connection) is
equivalent to starting bnep session. Bnep session handles data queue of
transmit, receive messages over bnep channel. It means that if we add
connection the received/transmitted data will be parsed immediately. In
case of get bnep features we want to know before session start, if we
should leave setup data on socket queue and let kernel to handle with it,
or in case of no setup handling support, if we should pull this message
and handle setup response within user space.

Probe deferral is not an error case. It happens only when
the necessary dependencies are not there yet.
The driver core is already printing a message when a driver
requests probe deferral, so this can be traced in the logs
without these error prints.
This patch removes the error messages for these deferral cases.

Stas Sergeev says:
====================
mvneta: SGMII-based in-band link state signaling
Currently the fixed-link DT binding is pre-configured and
cannot be changed in run-time. This means the cable unplug
events are not being detected, and the link parameters can't
be negotiated.
The following patches are needed when mvneta is used
in fixed-link mode (without MDIO).
They add an API to fixed_phy that allows to update
status, and use that API in the mvneta driver when parsing
the SGMII in-band status.
There is also another implementation that doesn't add any API
and does everything in mvneta driver locally:
https://lkml.org/lkml/2015/3/31/327
I'll let people decide which approach is better.
No strong opinion on my side.

When MDIO bus is unavailable (common setup for SGMII), the in-band
signaling must be used to correctly track link state.
This patch enables the in-band status delivery for link state changes, namely:
- link up/down
- link speed
- duplex full/half
fixed_phy_update_state() is used to update phy status.

Currently fixed_phy uses a callback to periodically poll the link state.
This patch adds the fixed_phy_update_state() API.
It solves the following problems:
- On link state interrupt, MAC driver can't update status.
Instead it needs to provide the callback to periodically query
the HW about the link state. It is more efficient to update status
after interrupt.
- The callback needs to be unregistered before phy_disconnect(),
or otherwise it will be called with net_dev==NULL. phy_disconnect()
does not have enough info to unregister the callback automatically.
- The callback needs to be registered before of_phy_connect() to
avoid running with outdated state, but of_phy_connect() returns the
phy_device pointer, which is needed to register the callback. Registering
it before of_phy_connect() will therefore require a hack to get the
pointer earlier.
Overall, this addition makes the subsequent patch that implements
SGMII link status for mvneta, much cleaner.

This adds the ability to read out the skb->priority from an eBPF
program, so that it can be taken into account from a tc filter
or action for the use-case where the priority is not being used
to directly override the filter classification in a qdisc, but
to tag traffic otherwise for the classifier; the priority can be
assigned from various places incl. user space, in future we may
also mangle it from an eBPF program.

Commit 3e457371f436 ("usb: musb: Fix fifo reads for dm816x with musb_dsps")
fixed a USB error on dm816x, but introduced a new build error on i386

readsl(fifo, dst, len >> 2);
Let's fix this by using ioread32_rep() instead of readsl() as that's
more portable.
