Package: klibc-utils
Version: 2.0.1-3.1
Attempting to PXE boot
IP-Config: fails to get DHCP configuration with "some" DHCP servers
I think I have found/solved this bug;
The problem is located at ipconfig (klibc-utils) not
implementing the DHCP standard as it should at the file
/klibc-xxx/usr/kinit/ipconfig/dhcp_proto.c
old:
static int dhcp_send(struct netdev *dev, struct iovec *vec)
{
...
bootp.yiaddr = dev->ip_addr; //this line must be replaced by the following
two lines
...
}
new:
static int dhcp_send(struct netdev *dev, struct iovec *vec)
{
...
bootp.yiaddr = INADDR_ANY; //the DHCP protocol says yiaddr=0 for
DICOVERY & REQUEST
bootp.flags = htons(0x800); //forgets to set broadcast answer;
previously setting unicast.
...
}
This bug does not affect 100% of the DHCP servers as some of
them are more forgiving than others with client protocol
mistakes;
for those needing a quick solution for PXE booting see/get
Serva complementary INITRD_N10.GZ which includes the already
patched ipconfig
