In 76226a34 ("ifup-eth: apply PERSISTENT_DHCLIENT to IPv6 dhclient daemon"),
one PERSISTENT_DHCLIENT option works for both IPv4 and IPv6, so the IPv4
and IPv6 settings are consistent. However, the user settings for IPv4 and IPv6
are limited.
For example, users try to adopt both IPv4 and IPv6 protocol. DHCPv6 servers
may be not stable as DHCP servers, thus the expectation for obtaining IPv6
address is lower than IPv4 address. For users, IPv4 address must be
obtained for the basic communication. So the PERSISTENT_DHCLIENT option is
set to be "yes | 1" for IPv4 address. However, the network service may be
stuck until it fails due to missing DHCPv6 servers, and the remaining devices also
cannot obtain both IPv4 and IPv6 addresses. The problem is very serious for users.
Here, I add a new PERSISTENT_DHCLIENT_IPV6 option only for IPv6 dhclient daemon,
so users can set IPv4 and IPv6 separately.

Introduced in the bonding driver (commit ae46f184bc1f) now reports transmission failures.
Before that, it silently dropped the packet and replied with success error code.
The arping of iputils retries endlessly when a transmission error occurs.
This patch fix this behavior.

Some interfaces like Open vSwitch bridges using the userspace datapath,
needs the link to be kept down to avoid issues.
Add a LINKSTATUS=[down|up] ifcfg parameter to add this functionality.
If not specified, the link will default to up as before.

Use internal network-scripts function net_log() instead of
/usr/bin/logger if possible to make code more consistent and cleaner.

Fix the problem when the device name could be interpreted as an iproute2 keyword.
For example, for a bridge slave named "a" the iproute2 would treat the name
as a prefix of keyword "address" and the network-scripts would fail to set
the bridge master.

In ifup/ifdown scripts, move deprecation waring info after
source_config, so users can config DEPRECATION_WARNING_ISSUED in
ifcfg-** file to decide whether show deprecation waring info when
calling ifup/ifdown.

IPv6 dhclient daemon only tries one time to obtain a IPv6 address
from a DHCPv6 server regardless of the setting of PERSISTENT_DHCLIENT.
PERSISTENT_DHCLIENT option is only used for IPv4 dhclient daemon.
With the popularization of IPv6 protocol, some users prefer setting
IPv6 like IPv4. I think there are two solutions as follows,
1. adopt PERSISTENT_DHCLIENT option to both IPv4 and IPv6.
2. create a new option, such as PERSISTENT_DHCLIENT_IPV6 option,
just for IPv6.
The first solution does not introduce addition options, and the IPv4
and IPv6 settings are consistent. So I perfer choosing the first
solution.

This was causing the /etc/resolv.conf file to be always updated when
RESOLV_MODS was not set...
Before the commit 5d6156454bf8f6dab4a5fdd7e1bf6 we were not updating
the /etc/resolv.conf file if the RESOLV_MODS was empty.
See https://bugzilla.redhat.com/show_bug.cgi?id=1610411 for more info.

Because the return value of 'convert2sec()' function can sometimes be
decimal, the follow up 'expr' call can fail, since 'expr' does not
support floating point calculations. This can sometimes lead to error:
"""
expr: non-integer argument
/etc/sysconfig/network-scripts/ifup-eth: line 91: [: 0: unary operator
expected
"""
To solve this bug, we switch to 'bc' utility, which supports floating
point computations. We also have to change the comparison condition of
$LINKDELAY and $forward_delay to use 'bc' as well.

In case of 'network' service these warnings are displayed only once,
to not spam unnecessarily user's journalctl if they have many NICs.

When converting from brctl to ip-link, the call to exit in case bridge
adding failed was dropped by accident.
|
| |
|
|
|
| |
Since ip-link has full support for Linux bridges (and slave ports), use
that instead of the deprecated brctl from bridge-utils.

For currently unknown reason the dbus-send calls will fail to set the
firewall zone for the given interface if we omit the --print-reply
option...
This looks like some kind of race-condition in dbus-send, since the
--print-reply makes the call synchronous and slower.
Hopefully this is only a temporary workaround until DBus is fixed.

This was causing the DBus call to fail, and we didn't catch it before
since we were forwarding everything into /dev/null...

This concept is quite outdated, and not sane to use at all.
