* netifd: read udhcpc user scripts from directoryLeon M. George2021-04-171-0/+3
| | | | | | | | | | | | | | Placeholder DHCP user scripts were added recently. These files make package-based installations of such scripts more difficult. Pull user callbacks from directories instead to allow packages and users to install co-existing scripts more easily.

* netifd: add a udhcpc.user placeholder scriptRui Salvaterra2021-03-101-0/+1
| | | | | | | | Document the existence of this feature. This allows the user to execute a script at each DHCPv4 event. This is useful, for example, as an ad-hoc way to update a DDNS entry when (and only when) required. Signed-off-by: Rui Salvaterra <rsalvaterra@gmail.com>

* netifd: change RPS/XPS handling to all CPUs and disable by defaultAlan Swanson2020-03-031-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation is significantly lowering lantiq performace [1][2] by using RPS with non-irq CPUs and XPS with alternating CPUs. The previous netifd implementation (by default but could be configured) simply used all CPUs and this patch essentially reverts to this behaviour. The only document suggesting using non-interrupt CPUs is Red Hat [3] where if the network interrupt rate is extremely high excluding the CPU that handles network interrupts *may* also improve performance. The original packet steering patches [4] advise that optimal settings for the CPU mask seems to depend on architectures and cache hierarcy so one size does not fit all. It also advises that the overhead in processing for a lightly loaded server can cause performance degradation. Ideally, proper IRQ balancing is a better option with the irqbalance daemon or manually. The kernel does not enable packet steering by default, so also disable in OpenWRT by default. (Though mvebu with its hardware scheduling issues [5] might want to enable packet steering by default.) Change undocumented "default_ps" parameter to clearer "packet_steering" parameter. The old parameter was only ever set in target/linux/mediatek/base-files/etc/uci-defaults/99-net-ps and matched the default.

| | | | | | | | | | | | | | | | | | commit eb204d14f75c ("base-files: implement generic service_running") introduced generic service_running so it's not needed to copy&paste same 3 lines over and over again. I've removed service_running from netifd/network init script as well, because it was not working properly, looked quite strange and I didn't understand the intention: $ /etc/init.d/network stop $ service network running && echo "yes" || echo "nope" ( have to wait for 30s ) Command failed: Request timed out yes Signed-off-by: Petr Štetiar <ynezz@true.cz>

* netifd: add udhcpc link check to dhcp shell handler scriptHans Dedecker2018-03-021-0/+2
| | | | | | | | Fixes the assumption the busybox udhcpc applet is always enabled; in case the symbolic link check fails the DHCP shell handler script will exit and as result the DHCP protocol handler will not be registered in netifd. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* netifd: update dhcp.script to handle dynamic routingMogula Pranay2018-01-101-1/+7
| | | | | | | | | | | | Certain DHCP servers push a gateway outside of the assigned interface subnet, to support those situations, install a host route towards the gateway. If Gateway and IP are served in same network, openwrt quagga cannot learn routes (rip routes are not getting added, showing inactive) whereas working fine when Gateway and IP are in different network.

* netifd: Request DHCP option 121 (classless route) by defaultBaptiste Jonglez2016-10-261-2/+5
| | | | | | | | | | | | | | | | | | | This option, defined by RFC3442, allows a DHCP server to send static routes to a client. But the client has to request this option explicitely. Static routes are useful when the gateway configured by DHCP cannot be in the same subnet as the client. This happens, for instance, when using DHCP to hand out addresses in /32 subnets. A new configuration option "classlessroute" is available, allowing users to disable this feature (the option defaults to true). Other DHCP clients already request this option by default (dhcpcd, for instance, and possibly Windows). If a DHCP server does not support this option, it will simply ignore it.

| | | | | | | | | | | | | Commit ce92f6650bd8a86db04c7a6cbb58e7fdb200a7e6 added source IP support for DHCP default routes. As a side effect of this change the default route could be present twice in netifd (once with source IP set and once with source IP unset) if it was sent by the server in both the router and static route options. Therefore add source IP support as well for static routes as this case was not considered. Additional remove unused parameter type.
