* net: retire global NetRxPackets arraysAhmad Fatoum2024-03-131-2/+0

| | | | | | | | | | | We have a number of drivers that call net_alloc_packet in a loop and will gain some more in the quest to drop NetRxPackets.

* net: add generic MAC address derivation from machine IDAhmad Fatoum2023-11-221-0/+2
| | | | | | | | | | | | | | | Especially during development, devices often lack a MAC address. While a MAC address can be easily added to the environment: nv dev.eth0.ethaddr="aa:bb:cc:dd:ee:ff" It's easily lost when flashing complete new images, e.g. from CI. Make the development experience neater by deriving a stable MAC address if possible.

* net: ifup: have ifup -a1 stop at first DHCP-set global.net.serverAhmad Fatoum2023-02-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The normal use case for ifup -a is to get *some* interface working and not really wait for all interfaces to come up and then timeout waiting for those without link up to never get a DHCP lease. When using automounts with a previously empty $global.net.server, we know this to be the case, because the first DHCP interface will set the variable and all remaining ones won't affect this. Therefore, let's add a ifup -a1 option, which would stop after $global.net.server was set via DHCP. This is a special case of a possible future ifup -ar, which would check after each ifup if $global.net.server was either newly set or became resolvable, but that would be a bigger change, so we skip that for now.

* net: ifup: have ifup -a poll for link up in parallelAhmad Fatoum2023-02-031-0/+3
| | | | | | | | | | | | | | | | | DHCP is usually fairly quick, but link up check timeout is 10 seconds, which adds up, especially on systems with bigger DSA switches. The workaround is to set ethX.mode=disabled for other ports, but let's improve the default a bit and have barebox poll link ups in parallel, so instead of (number_of_ports_wihout_link * 10s), we just wait 10s at most. For setups where this is a problem, users may revert to ifup in sequence by doing ifup -a -s.

| | | | | | | | | | | | | The '_d' suffix was originally introduced in case we want to import Linux struct device as a separate struct into barebox.

* net: Bring up all interfaces when going interactiveSascha Hauer2022-09-221-0/+3
| | | | | | | | | | | | | | So far we only bring up network interfaces when we actually need them. This means we could be idling in the shell for long and once the user decides to do networking he has to wait for the link to be established. We can do better: Before going interactive bring up all known network interfaces which makes the links established when the user needs them. To implement this we have to rework carrier checking a bit, because otherwise barebox would wait for the links to be established before continuing.

* net: dns: return error codesSascha Hauer2018-11-291-5/+3
| | | | | | | | | | | | | | The resolv() function used to return the IP address. When net_udp_new() fails we return an error code though which the callers of resolv() take as an IP address. This is wrong of course and we could return 0 in this case. Instead we return an error code and pass the resolved IP as a pointer which allows us to return proper error codes. This patch also adds error messages and error returns to the various callers of resolv() which used to just continue with a zero IP and let the user figure out what went wrong.

* net: Add linuxdevname propertySascha Hauer2017-12-151-0/+1
| | | | | | | | | | | | | | | | | When you have a static network environment but more than one network device on your machine it is necessary to provide the <device> parameter to the ip parameter at kernel cmd line. The device name assigned by Linux cannot in general be predicted as it depends on driver bind order. This patch introduces a new property linux.devname to eth devices.

A network interface can now be configured with variables in the nv.dev.<ethname>.* namespace. There is a new network device parameter "mode" which specifies the mode used to obtain IP settings. The mode can be "dhcp", "static" or "disabled": nv.dev.eth0.mode=dhcp (ipaddr, netmask are ignored in this setting) nv.dev.eth0.mode=static nv.dev.eth0.ipaddr=192.168.0.17 nv.dev.eth0.netmask=255.255.0.0 nv.dev.eth0.mode=disabled Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* net: Use a single gatewaySascha Hauer2017-12-011-1/+1
| | | | | | | | | | | | | | There is not much point in having a network device specific gateway. If barebox really is part of such a complicated network in which it needs multiple gateways, then we probably need a real routing table. Until this happens, a single gateway should be enough. This introduces global.net.gateway which holds the gateway ip. The previously used device specific <ethx>.gateway variables still exist, but are only aliases for the single gateway.

* net: dhcp: Do not overwrite serverip if it is validSascha Hauer2017-12-011-0/+1
| | | | | | | | | | | | | Some DHCP servers provide the wrong serverip in which case it is desired to specify it manually and won't let the dhcp command overwrite it. This has previously been done by setting the serverip again to the desired value after dhcp has been executed. With this patch we do not overwrite it in the first place if it is valid already. This is necessary when the serverip is not set via /env/network/eth* but via nv.net.server. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: introduce global.net.serverSascha Hauer2017-12-011-1/+0
| | | | | | | | | | | | The server to use is independent of the network device, there is not much point to make the server specific to a network device. This introduces global.net.server as the serverip which is used as standard NFS/tftp server.

| | | | | | | | | | | | | | | | In barebox network packets always go out at the current ethernet device and are expected to be received from the current interface. This has some side effects. When for example an NFS is mounted when one interface is active and the interface is changed afterwards the NFS packets leave the new interface, but the NFS server won't be reachable there. Instead of changing the whole network traffic to the current ethernet interface we now initialize a network connection with the current network interface, but then the connection will continue to use that interface even when the current interface is changed.
