net: eth-uclass: Fix for DM USB ethernet support

2018-08-21T14:21:37+00:00

When a USB ethernet device is halted, the device driver is removed. When
this happens the uclass private memory is freed and uclass_priv is set to
NULL. This causes a data abort when uclass_priv->state is then set to
ETH_STATE_PASSIVE.

Fix it by checking if uclass_priv is NULL before setting uclass_priv->state

net: Consolidate the parsing of bootfile

2018-07-26T19:08:20+00:00

The same basic parsing was implemented in tftp and nfs, so add a helper
function to do the work once.

net: Read bootfile from env on netboot_common()

2018-07-26T19:08:20+00:00

Instead of depending on a env callback for bootfile, read it explicitly.

We do this because the bootfile can be specified on the command line and
if it is, we will overwrite the internal variable. If a netboot_common()
is called again with no bootfile parameter, we want to use the one in
the environment.

net: Make copy_filename() accept NULL src

2018-07-26T19:08:20+00:00

Rather than crashing, check the src ptr and set dst to empty string.

net: Re-check prerequisites when autoloading

2018-07-26T19:08:20+00:00

With net autoload, we check the prerequisites for the initial command,
but the greater prerequisites when autoloading are not checked.

If we would attempt to autoload, check those prerequisites too.

If we are not expecting a serverip from the server, then don't worry
about it not being set, but don't attempt to load if it isn't.

net: When checking prerequisites, consider boot_file_name

2018-07-26T19:08:19+00:00

For net_boot_common, we allow the serverip to be specified as part of
the boot file name. For net commands that require serverip, include that
source as a valid specification of serverip.

net: Always print basic info for nfs, just like tftp

2018-07-26T19:08:19+00:00

nfs was only printing basic info about the transfer in the case of a
DEBUG build. Print the same level of detail as tftp always.

net: Check subnet against the actual ip address in use for nfs

2018-07-26T19:08:19+00:00

The check for sending to the gateway was not using the correct variable
for comparison, so it was reporting that packets are sent to the gateway
when they were not.

net: Only call halt on a driver that has been init'ed

2018-07-26T19:08:17+00:00

With driver model, we were not checking if the state of the device was
marked as active before calling the halt function. Check that the device
is probed and also marked as active. This avoids the case where we were
calling halt on the first device in net_init() and the driver would
operate on bogus data structures causing problems. In this case, the
priv was all 0, so halt() would close STDIN.
