netdevsim: add support for flash_update overwrite mask

2020-09-26T00:20:57+00:00

The devlink interface recently gained support for a new "overwrite mask"
parameter that allows specifying how various sub-sections of a flash
component are modified when updating.

Add support for this to netdevsim, to enable easily testing the
interface. Make the allowed overwrite mask values controllable via
a debugfs parameter. This enables testing a flow where the driver
rejects an unsupportable overwrite mask.

devlink: convert flash_update to use params structure

2020-09-26T00:20:57+00:00

The devlink core recently gained support for checking whether the driver
supports a flash_update parameter, via `supported_flash_update_params`.
However, parameters are specified as function arguments. Adding a new
parameter still requires modifying the signature of the .flash_update
callback in all drivers.

Convert the .flash_update function to take a new `struct
devlink_flash_update_params` instead. By using this structure, and the
`supported_flash_update_params` bit field, a new parameter to
flash_update can be added without requiring modification to existing
drivers.

As before, all parameters except file_name will require driver opt-in.
Because file_name is a necessary field to for the flash_update to make
sense, no "SUPPORTED" bitflag is provided and it is always considered
valid. All future additional parameters will require a new bit in the
supported_flash_update_params bitfield.

devlink: refactor end checks in devlink_nl_cmd_region_read_dumpit

2020-05-15T00:36:25+00:00

Clean up after recent fixes, move address calculations
around and change the variable init, so that we can have
just one start_offset == end_offset check.

Make the check a little stricter to preserve the -EINVAL
error if requested start offset is larger than the region
itself.

devlink: let kernel allocate region snapshot id

2020-05-04T18:58:31+00:00

Currently users have to choose a free snapshot id before
calling DEVLINK_CMD_REGION_NEW. This is potentially racy
and inconvenient.

Make the DEVLINK_ATTR_REGION_SNAPSHOT_ID optional and try
to allocate id automatically. Send a message back to the
caller with the snapshot info.

Example use:
$ devlink region new netdevsim/netdevsim1/dummy
netdevsim/netdevsim1/dummy: snapshot 1

$ id=$(devlink -j region new netdevsim/netdevsim1/dummy | \
       jq '.[][][][]')
$ devlink region dump netdevsim/netdevsim1/dummy snapshot $id
[...]
$ devlink region del netdevsim/netdevsim1/dummy snapshot $id

v4:
 - inline the notification code
v3:
 - send the notification only once snapshot creation completed.
v2:
 - don't wrap the line containing extack;
 - add a few sentences to the docs.

netdevsim: Change dummy reporter auto recover default

2020-03-30T18:17:34+00:00

Health reporters should be registered with auto recover set to true.
Align dummy reporter behaviour with that, as in later patch the option to
set auto recover behaviour will be removed.

In addition, align netdevsim selftest to the new default value.

selftests: devlink: undo changes at the end of resource_test

2019-11-06T19:11:30+00:00

The netdevsim object is reused by all the tests, but the resource
tests puts it into a broken state (failed reload in a different
namespace). Make sure it's fixed up at the end of that test
otherwise subsequent tests fail.
