Kernel version 2.4.8-ac9
I am attempting to set up a linux based xterm. The kernel loads
but times out attempting to get ipaddresses etc in ipconfig.
The following are defined in "include/linux/autoconf.h":
#define CONFIG_IP_PNP 1
#define CONFIG_IP_PNP_DHCP 1
#define CONFIG_IP_PNP_BOOTP 1
#undef CONFIG_IP_PNP_RARP
A few printk's latter and it seems that the problem is in ic_bootp_recv()
around line 843:
#ifdef IPCONFIG_DEBUG
printk("DHCP: Got message type %d\n", mt);
#endif
switch (mt) {
case DHCPOFFER:
[.....]
default:
/* Urque. Forget it*/
ic_myaddr = INADDR_NONE;
ic_servaddr = INADDR_NONE;
goto drop;
}
At this point we could be receiving either DHCP *or* BOOTP extensions.
The code to handle the BOOTP extension follows, but is never executed
because of the "goto drop" in the default case for handling dhcp packets.
If the kernel were compiled without DHCP this problem would go away.
There are two possibilities to fix this. One is to fall through to the
bootp case instead of going to drop, or maybe fold the bootp code into
the default case of the switch statement. The only problem then seems to
be how to conditionalize the DHCP support.
