[IPCONFIG]: ip_auto_config fix
The following commandline:
root=/dev/mtdblock6 rw rootfstype=jffs2 ip=192.168.1.10:::255.255.255.0:localhost.localdomain:eth1:off console=ttyS0,115200
makes ip_auto_config fall back to DHCP and complain "IP-Config: Incomplete
network configuration information." depending on if CONFIG_IP_PNP_DHCP is
set or not.
The only way I can make ip_auto_config accept my IP config is to add an
entry for the server IP:
ip=192.168.1.10:192.168.1.15::255.255.255.0:localhost.localdomain:eth1:off
I think this is a bug since I am not using a NFS root FS.
The following patch fixes the above problem.
From: Andrew Morton <akpm@linux-foundation.org>
Davem said (in February!):
Well, first of all the change in question is not in 2.4.x either. I just
checked the current 2.4.x GIT tree and the test is exactly:
if (ic_myaddr == INADDR_NONE ||
#ifdef CONFIG_ROOT_NFS
(MAJOR(ROOT_DEV) == UNNAMED_MAJOR
&& root_server_addr == INADDR_NONE
&& ic_servaddr == INADDR_NONE) ||
#endif
ic_first_dev->next) {
which matches 2.6.x
I even checked 2.4.x when it was branched for 2.5.x and the test was the
same at the point in time too.
Looking at the proposed change a bit it appears that it is probably
correct, as it's trying to check that ROOT_DEV is nfs root. But if it is
correct then the UNNAMED_MAJOR comparison in the same code block should be
removed as it becomes superfluous.
I'm happy to apply this patch with that modification made.
