We use an empty hostname, so remove all the "processing" of the known-to-be-empty hostname and just write 0's where needed. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Use the tx buffer to construct rpc msgsJoe Hershberger
Instead of always allocating a huge temporary buffer on the stack and then memcpy()ing the result into the transmit buffer, simply figure out where in the transmit buffer the bytes will belong and write them there directly as each message is built. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Move some prints to debug statementsJoe Hershberger
Much of the information is verbose and derived directly from the environment. Only output in debug mode. This also saves about 300 bytes from the code size. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

2016-08-22net: nfs: Correct the reply data buffer sizeJoe Hershberger
The type of the buffer is uint32_t, but the parameter used to size it is referring to bytes. Divide by the size of the array elements. Strictly speaking, this shouldn't be needed at all... It could just be 1 just like the request. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: nfs: Share the file handle buffer for v2 / v3Joe Hershberger
The v3 handles can be larger than v2, but that doesn't mean we need a separate buffer. Reuse the same (larger) buffer for both. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2016-08-22net: NFS: Add NFSv3 supportGuillaume GARDET
This patch enables NFSv3 support. If NFSv2 is available use it as usual. If NFSv2 is not available, but NFSv3 is available, use NFSv3. If NFSv2 and NFSv3 are not available, print an error message since NFSv4 is not supported. Tested on iMX6 sabrelite with 4 Linux NFS servers: * NFSv2 + NFSv3 + NFSv4 server: use NFSv2 protocol * NFSv2 + NFSv3 server: use NFSv2 protocol * NFSv3 + NFSv4 server: use NFSv3 protocol * NFSv3 server: use NFSv3 protocol Signed-off-by: Guillaume GARDET <guillaume.gardet@free.fr> Cc: Tom Rini <trini@konsulko.com> Cc: joe.hershberger@ni.com Acked-by: Joe Hershberger <joe.hershberger@ni.com>

2016-08-22net: Stop including NFS overhead in defragment maxJoe Hershberger
At least on bfin, this "specimen" is actually allocated in the BSS and wastes lots of memory in already tight memory conditions. Also, with the introduction of NFSv3 support, this waste got substantially larger. Just remove it. If a board needs a specific different defragment size, that board can override this setting.

2016-05-27net: Optionally use pxe client arch from variableAlexander Graf
The client architecture that we pass to a dhcp server depends on the target payload that we want to execute. An EFI binary has a different client arch than a legacy binary or a u-boot binary. So let's parameterize the pxe client arch field to allow an override via the distro script, so that our efi boot path can tell the dhcp server that it's actually an efi firmware. Signed-off-by: Alexander Graf <agraf@suse.de>
2016-05-27distro: Add efi pxe boot codeAlexander Graf
Now that we can expose network functionality to EFI applications, the logical next step is to load them via pxe to execute them as well. This patch adds the necessary bits to the distro script to automatically load and execute EFI payloads. It identifies the dhcp client as a uEFI capable PXE client, hoping the server returns a tftp path to a workable EFI binary that we can then execute. To enable boards that don't come with a working device tree preloaded, this patch also adds support to load a device tree from the /dtb directory on the remote tftp server.

There are client identifiers specifically reserved for ARM U-Boot according to http://www.ietf.org/assignments/dhcpv6-parameters/dhcpv6-parameters.xml#processor-architecture. So let's actually make use of them rather than the bogus 0x100 that we emitted so far.

2016-05-27net: Move the VCI and client arch values to KconfigAlexander Graf
We have a bunch of boards that define their vendor class identifier and client archs in the board files or in the distro config. Move everything to the generic Kconfig options. We're missing the distinction between i386 and x86_64, as I couldn't find any config variable that would tell us the difference. Is that really important to people? I guess not, so I left it out.

2016-05-27efi_loader: Add network access supportAlexander Graf
We can now successfully boot EFI applications from disk, but users may want to also run them from a PXE setup. This patch implements rudimentary network support, allowing a payload to send and receive network packets. With this patch, I was able to successfully run grub2 with network access inside of QEMU's -M xlnx-ep108. Signed-off-by: Alexander Graf <agraf@suse.de>
2016-03-27bootp: Prevent u-boot from using others responses.Anton Persson
In rare circumstances two dhcp clients may generate the same bootp ID. If this happens it is vital that the client also checks the hw address in the received response to prevent IP address conflicts. Signed-off-by: Anton Persson <don.juanton@gmail.com>
2016-02-26net: bootp: Add environment variable for timeout periodAlexandre Messier
There is currently one config option (CONFIG_NET_RETRY_COUNT) that is available to tune the retries of the network stack. Unfortunately, it is global to all protocols, and the value is interpreted differently in all of them. Add a new environment variable that directly sets the retry period for BOOTP timeouts. If this new value is not set, the period is still derived from the default number of retries, or from CONFIG_NET_RETRY_COUNT if defined. When both the new variable is set and CONFIG_NET_RETRY_COUNT is defined, the variable has precedence. Signed-off-by: Alexandre Messier <amessier@tycoint.com>

2016-01-28net: bootp: Ignore packets whose yiaddr is 0Peng Fan
When doing `dhcp`, there is a bad dhcp server in my network which always reply dhcp request with yiaddr 0, which cause uboot can not successfully get ipaddr from the good dhcp server. But the Linux PC can get the ip address even if there is a bad dhcp server. This patch is to fix that even if there is a bad dhcp server, uboot can still get ipaddr and tftp work ok. The way is to ignore the packets from the bad dhcp server by filtering out the yiaddr whose value is 0.

2016-01-07net: Fix delay in net_retry testJoe Hershberger
Introduced in 45b4773 (net/arp: account for ARP delay, avoid duplicate packets on timeout) Check the arp timeout and adjust the timeout start time before the call to eth_recv() so that the sandbox driver has the opportunity to adjust the sandbox timer after the new start time has been recorded. Also, change the adjustment amount by 11 seconds instead of exactly the 10 seconds that the ping timout is expecting since the timeout check is looking for the time elapsed to be greater than but not equal to the specified delay.
