2018-07-02net: Add option to prefer bootp/dhcp serveripAlexander Graf
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.

2018-07-02net: Prefer command line argumentsAlexander 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 <agraf@suse.de> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

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.

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.

2014-08-21net: More BOOTP retry timeout improvementsThierry Reding
It's not unusual for DHCP servers to take a couple hundred milliseconds to respond to DHCP discover messages. One possible reason for the delay can be that the server checks (typically using an ARP request) that the IP it's about to hand out isn't in use yet. To make matters worse, some servers may also queue up requests and process them sequentially, which can cause excessively long delays if clients retry too fast. Commit f59be6e850b3 ("net: BOOTP retry timeout improvements") shortened the retry timeouts significantly, but the BOOTP/DHCP implementation in U-Boot doesn't handle that well because it will ignore incoming replies to earlier requests. In one particular setup this increases the time it takes to obtain a DHCP lease from 630 ms to 8313 ms. This commit attempts to fix this in two ways. First it increases the initial retry timeout from 10 ms to 250 ms to give DHCP servers some more time to respond. At the same time a cache of outstanding DHCP request IDs is kept so that the implementation will know to continue transactions even after a retransmission of the DISCOVER message. The maximum retry timeout is also increased from 1 second to 2 seconds. An ID cache of size 4 will keep DHCP requests around for 8 seconds (once the maximum retry timeout has been reached) before dropping them. This should give servers plenty of time to respond. If it ever turns out that this isn't enough, the size of the cache can easily be increased. With this commit the DHCP lease on the above-mentioned setup still takes longer (1230 ms) than originally, but that's an acceptable compromise to improve DHCP lease acquisition time for a broader range of setups. To make it easier to benchmark DHCP in the future, this commit also adds the time it took to obtain a lease to the final "DHCP client bound to address x.x.x.x" message.

2014-08-09net: BOOTP retry timeout improvementsStephen Warren
Currently, the BOOTP code sends out its initial request as soon as the Ethernet driver indicates "link up". If this packet is lost or not replied to for some reason, the code waits for a 1s timeout before retrying. For some reason, such early packets are often lost on my system, so this causes an annoying delay. To optimize this, modify the BOOTP code to have very short timeouts for the first packet transmitted, but gradually increase the timeout each time a timeout occurs. This way, if the first packet is lost, the second packet is transmitted quite quickly and hence the overall delay is low. However, if there's still no response, we don't keep spewing out packets at an insane speed. It's arguably more correct to try and find out why the first packet is lost. However, it seems to disappear inside my Ethenet chip; the TX chip indicates no error during TX (not that it has much in the way of reporting...), yet wireshark on the RX side doesn't see any packet. FWIW, I'm using an ASIX USB Ethernet adapter. Perhaps "link up" is reported too early or based on the wrong condition in HW, and we should add some fixed extra delay into the driver. However, this would slow down every link up event even if it ends up not being needed in some cases. Having BOOTP retry quickly applies the fix/WAR to every possible Ethernet device, and is quite simple to implement, so seems a better solution.
