* net: add generic MAC address derivation from machine IDAhmad Fatoum2023-11-223-5/+76
| | | | | | | | | | | | | | | 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: don't redo ifup -a1 if we have a gatewayAhmad Fatoum2023-07-261-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ifup -a -1 is an optimization for switches that have only one port connected: ifup will poll link on all ports in parallel and early exit once any port got an IP address. This doesn't work when global.net.server is set, as the first port to get link up is not necessary one that is in a network that can resolve global.net.server. This is needlessly restrictive: Even if global.net.server is set, it's only a problem if no gateway was set. If there's a gateway, barebox already knows how to resolve global.net.server, so there's no need to try to bring up all interfaces when -1 is supplied. This fixes the delay when using ifup -a1 multiple times in a row.

| | | | | | | | | | | | | | | | | | | | | | | | | | When global.net.server is set, barebox will attempt to bring up all interfaces on ifup -a1 to see which interface can resolve it. That can take a while and there's no way to abort that, so stick in a ctrlc(), so user can change their mind (and e.g. remove global.net.server, so ifup -a1 takes first interface that has link up).

* | net.c: Don't forget about the first fragment.Christian Melki2023-07-281-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible to request very large messages using the current code base. F.ex. UDP datagrams with the tftp client. The tftp servers will happily reply with fragmented IP frames. All these frame parts need to be dropped as BB currently doesn't do fragment reassembly. The current check was for fragment offsets only (0x1fff). But the first frame has fragment offset 0 and would slip through this check. That could result in a seemingly OK frame for the tftp client, but with broken data. Add check for the MF (More Fragments) flag. Should cover the first packet too.

* net: ifup: pass hostname and linuxdevname to linux with DHCPMichael Olbrich2023-05-021-2/+6
| | | | | | | | | | | | | Barebox always uses the hostname in the DHCP request. To configure kernel networking, use the long ip= syntax for DHCP and set the hostname as well. This way, Barebox and Linux use the same hostname in the DHCP request. Also set the device if linuxdevname is configured. This is already done for static configurations. Do the same for DHCP.

* net: ifup: have ifup -a1 stop at first DHCP-set global.net.serverAhmad Fatoum2023-02-032-4/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Fatoum2023-02-032-29/+102
| | | | | | | | | | | | | | | | | 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.

* net: Bring up all interfaces when going interactiveSascha Hauer2022-09-221-13/+21
| | | | | | | | | | | | | | 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: consult device tree for ethernet address in NVMEM as fall-backAhmad Fatoum2021-06-221-0/+24
| | | | | | | | | | | | | | | | | | | | | While barebox fixes up the mac-address into the device tree, it doesn't care much for extracting a mac address _from_ the device tree, whether it be from local-mac-address property or from a mac-address nvmem cell. Fix the latter by calling of_get_mac_addr_nvmem for each Ethernet adapter. We do this in a very late initcall, because we don't want to enforce a probe a probe order between nvmem providers and network devices. We can't do it at randomization time, because we need to fixup Ethernet mac addresses, even when barebox itself doesn't ifup the netdev. of_get_mac_addr_nvmem could be replaced by of_get_mac_address to also parse local-mac-address and brethern, but justifying this change is left as a future exercise.

| | | | | | | | | | The commit d5d342d26368c1 ("net: Make domainname and nameserver globalvars") changes net.nameserver variable name to global.net.nameserver. This commit changes the variable name in the error message too.

| * fastboot/dfu: use system partitions as fall backAhmad Fatoum2021-05-121-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Use the new system partitions infrastructure to have fastboot and DFU fall back to using the same partitions if the global.usbgadget.dfu_function and global.fastboot_partitions are not set, respectively. No functional change intended for configurations that have SYSTEM_PARTITIONS disabled.

| * common: make FILE_LIST feature unconditionalAhmad Fatoum2021-05-121-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | CONFIG_FILE_LIST controls whether the file_list_* family of functions are compiled. common/file-list.o does not register any initcalls and there is no code that is dependent on it being available: it's selected as required. This means linker GC can completely get rid of it if required, so drop the symbol.

* fs: introduce unsetenv() to prepare for changing setenv(var, "") behaviorAhmad Fatoum2020-11-231-1/+1
| | | | | | | | | | | | | | | | | Currently, we treat setenv(var, "") and setenv(var, NULL) the same and delete var, which is surprising and leads to subtle quirks: - setenv(var, "") is specified by POSIX to set var to an empty string, but barebox uses it to delete variables - nv.user= calls nv_set with NULL parameter, but nv user="" doesn't Make the API more POSIX-like by providing unsetenv with the expected semantics. Most user code can then use unsetenv without worrying about whether "" or NULL is the magic deletion value.

* fastboot net: implement fastboot over UDPEdmund Henniges2020-08-193-0/+594
| | | | | | | | | | | | | | This implements the UDP variant of the fastboot protocol. The only way to start the service for now is to compile with CONFIG_FASTBOOT_NET_ON_BOOT. The service will bind to the network interface that provides the IPv4 gateway. Sending an OKAY packet before performing a restart is necessary since contrary to USB the host will not notice when a UDP server disappears.

* net: reply to ping requestsSascha Hauer2020-08-191-2/+44
| | | | | | | Now that we have the network receive function running in a poller we can reasonably well answer to ping requests. Implement this feature. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: Call net_poll() in a pollerSascha Hauer2020-08-193-5/+60
| | | | | | | | | | | | | | | This adds calling of net_poll() in a poller. With this we can react to incoming packets like ping requests or fastboot requests. We could change to call net_poll() from a poller exclusively, but this would significantly slow down USB network controllers. As described in the patch these take a long time in the packet receive path. To work around this we keep the networking users call net_poll() at a high rate when they are waiting for incoming packets and only every 10ms we call net_poll() from a poller to get incoming traffic when no networking protocol is actively calling net_poll().
