[PATCH] network-functions: add snapshot/rollback functions
by Dan Kenigsberg 01 Mar '10

01 Mar '10

When logging into a remote machine to play with its network configurations there the fear of locking yourself out always lurks. If this happens, you can walk to the remote machine and fix it, but it would be easier to reboot the machine, and have it rolled back to a known-good network configuration when it starts up. With this patch, you can use snapshot_config() to copy the current network configuration before changing it. The network service will use rollback_config() when the machine is rebooted. Use commit_config() when the current configuration is known to be good. Comments are welcome. Specifically, what should we copy but ifcfg-* and rule-* ? --- rc.d/init.d/network | 6 ++++ sysconfig/network-scripts/network-functions | 41 +++++++++++++++++++++++++++ 2 files changed, 47 insertions(+), 0 deletions(-) diff --git a/rc.d/init.d/network b/rc.d/init.d/network index 71e67ee..b789c31 100755 --- a/rc.d/init.d/network +++ b/rc.d/init.d/network @@ -44,6 +44,12 @@ cd /etc/sysconfig/network-scripts . ./network-functions +# when network starts afresh, roll back to last snapshot of network +# configurations. +if [ "$1" == start ]; then + rollback_config +fi + # find all the interfaces besides loopback. # ignore aliases, alternative configurations, and editor backup files interfaces=$(ls ifcfg* | \ diff --git a/sysconfig/network-scripts/network-functions b/sysconfig/network-scripts/network-functions index 89baeb4..6a1553e 100644 --- a/sysconfig/network-scripts/network-functions +++ b/sysconfig/network-scripts/network-functions @@ -361,3 +361,44 @@ change_resolv_conf () fi; return $r; } + +# take a snapshot of current network configuration scripts +snapshot_config () +{ + local snapshotdir + snapshotdir=/var/lib/initscripts/network-config + rm -fr "$snapshotdir" + mkdir -p "$snapshotdir" + for f in /etc/sysconfig/network-scripts/{ifcfg,rule}-* + do + [ -f "$f" ] && cp -p "$f" "$snapshotdir" + done +} + +commit_config () +{ + local snapshotdir + snapshotdir=/var/lib/initscripts/network-config + rm -fr "$snapshotdir" +} + +# rollback network configuration to last snapshot (if one exists) +rollback_config () +{ + local snapshotdir rollbackdir + snapshotdir=/var/lib/initscripts/network-config + # return immediately if there is no snapshot + [ ! -d "$snapshotdir" ] && return 0 + + rollbackdir=/var/log/initscripts/rollback-`date +%Y.%m.%d-%H:%M:%S` + mkdir -p "$rollbackdir" + for f in /etc/sysconfig/network-scripts/{ifcfg,rule}-* + do + [ -f "$f" ] && mv "$f" "$rollbackdir" + done + for f in "$snapshotdir"/{ifcfg,rule}-* + do + [ -f "$f" ] && mv "$f" /etc/sysconfig/network-scripts + done +} + -- 1.6.6.1

[PATCH 00/11] Add NetworkManager integration to initscripts
by Bill Nottingham 17 Feb '10

17 Feb '10

Here's the first cut of NM integration into initscripts. It passes basic testing. Known issues: - Bringing down of system connections that don't have DEVICE set in their configuration does not work. I'm not seeing how to get this with nmcli currently. Please review, including checking for any misuses of the nmcli interface. ifdown | 7 ++++++- ifup | 11 ++++++++++- ifup-eth | 2 +- network-functions | 39 ++++++++++++++++++++++++++++++++++++--- 4 files changed, 53 insertions(+), 6 deletions(-)

initscripts 9.05 released
by Bill Nottingham 15 Feb '10

15 Feb '10

Two notable changes: - We no longer use ethtool for checking link state; instead we rely on /sys/class/net/$DEVICE/carrier. This should work on more devices, and be simpler. - In init.d/functions:daemon(), we now pass '-m' to runuser, to not clear the environment. This matches the non-runuser case, allowing init scripts to pass configuration. And, as usual, assorted bugfixes. Full log attached. Bill

[PATCH] upstart-0.6.0-branch - emit started events also in daemon()
by Petr Lautrbach 04 Jan '10

04 Jan '10

Hi, at this moment, upstart events are emitted only from /etc/rc.d/rc when runlevel is changing. This patch adds emitting of started event also to daemon() function. There is check of existing $runlevel to avoid duplicity emit call from /etc/rc.d/rc Regards, Petr -- Petr Lautrbach, Red Hat, Inc.

[PATCH] upstart-0.6.0-branch - init needs to connect to system dbus server
by Petr Lautrbach 04 Jan '10

04 Jan '10

Hi, if the "initctl list" has to work for a regular user, then init has to be connected to dbus system bus. Upstart init tries to connect to system dbus at the start and when gets SIGHUP signal. So we need to send SIGHUP to init after messagebus service started. Event "started JOB=messagesbus" is already sent by /etc/rc.d/rc script when changing runlevel. Regards, Petr -- Petr Lautrbach, Red Hat, Inc.
