Make it possible to add TCP versions of the same, while reusing
IP portions. This patch should not change any behavior.Signed-off-by: Duncan Hare
Acked-by: Joe Hershberger -
Peter originally sent a fix, but it breaks a number of other things.
This addresses the original reported issue in a different way.That report was:
> U-Boot has 1 common buffer to send Ethernet frames, pointed to by
> net_tx_packet. When sending to an IP address without knowing the MAC
> address, U-Boot makes an ARP request (using the arp_tx_packet buffer)
> to find out the MAC address of the IP addressr. When a matching ARP
> reply is received, U-Boot continues sending the frame stored in the
> net_tx_packet buffer.
>
> However, in the mean time, if U-Boot needs to send out any network
> packets (e.g. replying ping packets or ARP requests for its own IP
> address etc.), it will use the net_tx_packet buffer to prepare the
> new packet. Thus this buffer is no longer the original packet meant
> to be transmitted after the ARP reply. The original packet will be
> lost.This instead uses the ARP tx buffer to send async replies in the case
where we are actively waiting for an ARP reply.Signed-off-by: Joe Hershberger

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

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.Signed-off-by: Joe Hershberger

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.Signed-off-by: Joe Hershberger

For net_boot_common, we allow the serverip to be specified as part of

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.Signed-off-by: Joe Hershberger

Currently we can choose between 2 different types of behavior for the
serverip variable:1) Always overwrite it with the DHCP server IP address (default)
2) Ignore what the DHCP server says (CONFIG_BOOTP_SERVERIP)This patch adds a 3rd option:
3) Use serverip from DHCP if no serverip is given
(CONFIG_BOOTP_PREFER_SERVERIP)With this new option, we can have the default case that a boot file gets
loaded from the DHCP provided TFTP server work while allowing users to
specify their own serverip variable to explicitly use a different tftp
server.Signed-off-by: Alexander Graf

We can call commands like dhcp and bootp without arguments or with
explicit command line arguments that really should tell the code where
to look for files instead.Unfortunately, the current code simply overwrites command line arguments
in the dhcp case with dhcp values.This patch allows the code to preserve the command line values if they
were set on the command line. That way the semantics are slightly more
intuitive.The reason this patch does that by introducing a new variable is that we
can not rely on net_boot_file_name[0] being unset, as today it's
completely legal to call "dhcp" and afterwards run "tftp" and expect the
latter to repeat the same query as before. I would prefer not to break
that behavior in case anyone relies on it.Signed-off-by: Alexander Graf

Add a new command 'wol': Wait for an incoming Wake-on-LAN packet or
time out if no WoL packed is received.
If the WoL packet contains a password, it is saved in the environment
variable 'wolpassword' using the etherwake format (dot or colon
separated decimals).Intended use case: a networked device should boot an alternate image.
It's attached to a network on a client site, modifying the DHCP server
configuration or setup of a tftp server is not allowed.
After power on the device waits a few seconds for a WoL packet. If a
packet is received, the device boots the alternate image. Otherwise
it boots the default image.This method is a simple way to interact with a system via network even
if only the MAC address is known. Tools to send WoL packets are
available on all common platforms.Some Ethernet drivers seem to pad the incoming packet. The additional
padding bytes might be recognized as Wake-on-LAN password bytes.By default enabled in pengwyn_defconfig.

Global variable "net_state" is used in net_loop() state-machine.
But it happens that some times the net_loop() can be called
multiple times in the same call stack. For example when the
netconsole is enabled and we print the message while some other
net protocol is in action. Netconsole will overwrite the "net_state"
and that will break the logic for earlier started protocol.To protect the state save and restore "net_state" variable each
time when we enter and exit net_loop().Signed-off-by: Leonid Iziumtsev

On devices that have their first network interface provided by a FPGA,
the initialization of further interfaces will fail if the FPGA is not
yet programmed. This leads to problems during factory setup when the
data is supposed to be loaded over secondary netowork interfaces.To avoid this, use the uclass_{first,next}_device_check functions to

As part of the main conversion a few files were missed. These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict. This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.Fixes: 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style")

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.Signed-off-by: Tom Rini

The "net_try_count" counter starts from "1".
And the "retrycnt" contains requested amount of retries.With current logic, that means that the actual retry amount
will be one time less then what we set in "netretry" env.
For example setting "netretry" to "once" will make "retrycnt"
equal "1", so no retries will be triggered at all.Fix the logic by changing the statement of "if" condition.
