5fda0d60c1e004d6581f29c006635a51cee81349 - add ability to set watchdog timeout for a shutdown

Thu, 03 Oct 2019 11:23:10 +0000

add ability to set watchdog timeout for a shutdownThis change allows to specify a watchdog(9) timeout for a systemshutdown. The timeout is activated when the watchdogd daemon isstopped. The idea is to a prevent any indefinite hang during latestages of the shutdown. The feature is implemented in rc.d/watchdogd,it builds upon watchdogd -x option.Note that the shutdown timeout is not actiavted when the watchdogdservice is individually stopped by an operator. It is also notactivated for the 'shutdown' to the single-user mode. In those cases itis assumed that the operator knows what they are doing and they havemeans to recover the system should it hang.Significant subchanges and implementation details:- the argument to rc.shutdown, completely unused before, is assigned to rc_shutdown variable that can be inspected by rc scripts- init(8) passes "single" or "reboot" as the argument, this is not changed- the argument is not mandatory and if it is not set then rc_shutdown is set to "unspecified"- however, the default jail management scripts and jail configuration examples have been updated to pass "jail" to rc.shutdown, just in case- the new timeout can be set via watchdogd_shutdown_timeout rc option- for consistency, the regular timeout can now be set via watchdogd_timeout rc option- watchdogd_shutdown_timeout and watchdogd_timeout override timeout specifications in watchdogd_flags- existing configurations, where the new rc options are not set, should keep working as beforeI am not particularly wed to any of the implementation specifics.I am open to changing or removing any of them as long as the providedfunctionality is the same (or very close) to the proposed one.For example, I think it can be implemented without using watchdogd -x,by means of watchdog(1) alone. In that case there would be a smallwindow between stopping watchdogd and running watchdog, but I think thatthat is acceptable.Reviewed by: bcr (man page changes)MFC after: 5 weeksRelnotes: yesDifferential Revision: https://reviews.freebsd.org/D21221 List of files: /src/share/examples/jails/jng

Sun, 28 Oct 2018 18:32:47 +0000

Fix jail examples in jib, jng, READMEThe provided example jail configs do not work for multiple interfaces.Multiple interfaces need to be specified as a comma separated list orusing multiple += lines in jail.conf. In the given example, a space-separated string is used, which doesn't work with multiple interfaces.Also added a note to the README about VIMAGE being built-in by defaulton amd64 in FreeBSD 12, with appropriate instructions for loading thenecessary netgraph ether module (ng_ether) since it is neither built-in nor autoloads.Submitted by: Ryan Moeller Reported by: Ryan Moeller MFC after: 3 daysSponsored by: Smule, Inc.Differential Revision: https://reviews.freebsd.org/D17697 List of files: /src/share/examples/jails/jng

Fri, 12 Feb 2016 01:41:40 +0000

Add syntax to disable MAC allocationAdding `!' before an interface name will disable MAC allocation, fallingback to driver mechanics. Alternatively adding `=' before an interface namecauses the MAC address to be cloned (for ng_bridge(4) back-end only). Whilehere, disable the auto-detection of wlan* since this knocks the host off;requiring the host that defines the jail to explicitly enable this featureby preceding the interface with `='.

Add support for bridging iwn(4) based wlan(4)Documented in iwn(4), "Only one virtual interface may be configured at anytime." However, netgraph with a cloned MAC address is able to communicateover an ng_eiface attached to an ng_bridge linked to the wlan(4) interface.While here, introduce syntax to specify the MAC address is to be cloned ifthe named interface begins with equals [=].
