[Devil-linux-develop] init.d/network script and dhcpd client

[Andrzej O. <an...@ma...>]

Dear Heiko,

There are totally not urgent fixes to the script init.d/network, but worth 
consideration with the next edition.

Tere are two problems with network starting script, occuring in rare cases.

First. The problem manifests itself when two or more interfaces has set 
DHCP=yes (which is quite rare for routers). network script starts dhcpcd 
client for each interface separately, but each involves a separate pid file 
with name of the device as the name suffix. To specify the name of pid file 
killproc function is ready but loadproc is not and therefore loadproc check 
the presence of common pid file. Therefore, the second instance of dhcpcd 
client does not start.

Fix requires modification of loadproc function (in functions) by adding the 
option of the form "-p name.pid" like in killproc and (in network script 
itself) callings to startup and stopping of dhcpcd client.

Second. The problem is when closing labeled interfaces, such as eth0:1, eth0:2 
etc -- labeled interfaces are not closing correctly. The interface definition 
files in the /etc/sysconfig/nic are elaborated in sequence of "ls" command. 
Labeled interface files are adding IP address to the main interface when 
opening and taken away at closing. When stopping interfaces, reverse list 
order is needed for closing labelled interfaces before main and, therefore, we 
need use the command "ls -1 -r". This change is needed only in script network.

Patches are included

Best regards
