busybox: udhcpc: fix 'ip route add' with multiple interfaces on the same network

2020-01-27T16:48:08+00:00

The udhcpc script fails to properly set a default route when: - 'ip' is present ($have_bin_ip -eq 1) - there are 2 or more interfaces connected to the same network (e.g. ethernet + wifi on the same home LAN / same DHCP server) In this case, when the first interface gets an address from DHCP (e.g. eth0), a default route is set correctly. When the second interface (e.g. wlan0) gets its address, 'ip route add' without 'dev $interface' sets the route on the other interface. The result looks like: # ip route default via 192.168.1.1 dev eth0 metric 5 default via 192.168.1.1 dev eth0 metric 10 # wrong dev here 192.168.1.0/24 dev eth0 scope link src 192.168.1.20 192.168.1.0/24 dev wlan0 scope link src 192.168.1.30 # The situation might go unnoticed until eth0 is disconnected, because only wlan0 is present but there is no route through wlan0. Fix by explicitly passing "dev $interface" to 'ip route add'. Note that all other 'ip' invocations already have "dev $interface" passed.

busybox: udhcpc: fix IPv6 support when using udhcpc

2020-01-21T12:52:53+00:00

The udhcpc script calls ip addr flush .. which flushes addresses of any address family, including IPv6. However, busybox udhcpc is IPv4 only and should not influence IPv6 addressing. Hence use ip addr flush with family constrait. The script particularly broke IPv6 SLAAC: Typically when udhcpc calls the script the kernel already assigned the IPv6 link-local address. The flush removes the link-local IPv6 address again and prohibits proper IPv6 operation such as SLAAC since neighbor discovery protocol relies on IPv6 link-local addressing.

busybox:udhcpc: Remove the routes from the right interface

2015-02-24T17:41:44+00:00

When using iproute2 to remove the route all default rules will be removed. Scope the removal by interface like it is done with ifconfig. (From OE-Core rev: 2127a57cb1b3d83f9f7640051403e47e485b132c) Signed-off-by: Holger Hans Peter Freyther Signed-off-by: Richard Purdie

busybox:udhcpc: Start with a metric of 10 for routes

2015-02-24T17:41:44+00:00

Linux allows to install multiple default routes with different metrics. Start with a metric above 0 to allow other parts of the system to install routes with a lower metric.

BusyBox: Fixing broadcast address is not fed and rightly initialized

2014-11-04T10:27:10+00:00

When using udhcpc along with ip command(/sbin/ip), broadcast address is not assigned. Broadcast address is successfully assigned when using udhcpc without ip command existence. with ip command: $ifconfig eth0|grep Bcast inet addr:128.224.162.141 Bcast:0.0.0.0 Mask:255.255.254.0 $ without ip command: $ifconfig eth0|grep Bcast inet addr:128.224.162.141 Bcast:128.224.163.255 Mask:255.255.254.0 $ /etc/udhcp.d/50default[simple.script] is called to set ip address by dhcp client, In case of ifconfig, it doesn't care of it's existence because it will automatically calculate broadcast address then assign it if there is no broadcast option. However in case of ip command, it requires broadcast address statically.

busybox:udhcpc: fix the root_is_nfs() function

2012-07-26T13:40:49+00:00

[YOCTO #2788] The system will be hung when udhcpc starts, if nfs is mounted at "/" directory and default route is different after starting udhcpc. The cause is that root_is_nfs() does not work after kernel-2.6.37, since the device name has been changed from /dev/root to ${IPADDR}:${NFSDIR} on /proc/mounts. which leads to remove the default routes to nfs server, Now we use a loose match to check if rootfs is nfs.

Major layout change to the packages directory

2010-08-27T14:29:45+00:00

Having one monolithic packages directory makes it hard to find things and is generally overwhelming. This commit splits it into several logical sections roughly based on function, recipes.txt gives more information about the classifications used. The opportunity is also used to switch from "packages" to "recipes" as used in OpenEmbedded as the term "packages" can be confusing to people and has many different meanings. Not all recipes have been classified yet, this is just a first pass at separating things out. Some packages are moved to meta-extras as they're no longer actively used or maintained.
