2019-01-24net: explicitly assign errno to return code in case of network failureThomas RIENOESSL
When dealing with two ethernet ports and having "netretry" set to "once", it could occur that the connection (e.g. an ARP request) failed, hence the status of the netloop was "NETLOOP_FAIL". Due to the setting of "netretry", the network logic would then switch to the other network interface, assigning "ret" with the return value of "net_start_again()". If this call succeeded we would return 0 (i.e. success) to the caller when in reality the network action failed.

2018-10-10net: Don't overwrite waiting packets with asynchronous repliesJoe 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.

2018-07-26net: Read bootfile from env on netboot_common()Joe Hershberger
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 <joe.hershberger@ni.com>

2018-07-26net: Re-check prerequisites when autoloadingJoe 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 <joe.hershberger@ni.com>

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>
2018-07-02net: Add new wol command - Wake on LANLothar Felten
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.

2018-06-13net: Protect net_state from reentrant net_loop()Leonid Iziumtsev
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().

2018-03-22net: Fix netretry conditionLeonid Iziumtsev
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.
