2019-09-04net: make net_random_ethaddr() more randomMichael Walle
The net_random_ethaddr() tries to get some entropy from different startup times of a board. The seed is initialized with get_timer() which has only a granularity of milliseconds. We can do better if we use get_ticks() which returns the raw timer ticks. Using this we have a higher chance of getting different values at startup.

2019-07-18net: unaligned copying of unsigned longHeinrich Schuchardt
The inline functions net_read_u32() and net_copy_u32() have been created to copy unaligned u32. But this is not obvious to the compiler. GCC 9.1 introduces a check -Werror=address-of-packed-member which leads to a build error on Travis CI: net/bootp.c: In function ‘dhcp_send_request_packet’: net/bootp.c:1011:27: error: taking address of packed member of ‘struct bootp_hdr’ may result in an unaligned pointer value [-Werror=address-of-packed-member] 1011 | net_copy_u32(&bp->bp_id, &bp_offer->bp_id); Change the type of the function parameters to void * to avoid the build error.

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.

2018-07-02net: 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 <[email protected]> Acked-by: Joe Hershberger <[email protected]>
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.

2015-09-29net: expose eth_is_active() function to test network device stateBernhard Nortmann
The previous eth_device struct returned by eth_get_dev() allowed code to directly query the state member field. However, with CONFIG_DM_ETH this data gets encapsulated (i.e. private), and eth_get_dev() returns a udevice struct 'abstraction' instead. This breaks legacy code relying on the former behaviour - e.g. netconsole. (see http://lists.denx.de/pipermail/u-boot/2015-June/216528.html) The patch introduces a method to retrieve the ethernet device state in a 'clean' and uniform way, supporting both legacy code and driver model.

2015-07-21dm: eth: Avoid blocking on packet receptionSimon Glass
Some devices can take a long time to work out whether they have a new packet or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do this, since it waits until it gets a new packet on the wire before allowing the USB bulk read packet to be submitted. At present with driver mode the Ethernet receive code reads 32 packets. This can take a very long time if we must wait for all 32 packets. The old code (before driver model) worked by reading a single set of packets from the USB device, then processing all the packets with in. It would be nice to use the same behaviour with driver model. Add a flag to the receive method which indicates that the driver should try to find a packet if available, by consulting the hardware. When the flag is not set, it should just return any packet data it has already received. If there is none, it should return -EAGAIN so that the loop will terminate.
