* When user_frac in the polling subsystem is low it is going to busy theAttilio Rao2009-05-3027-155/+280
| | | | | | | | | | | | | | | | | | | | | | | | CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped). Bump __FreeBSD_version in order to signal such situation. Reviewed by: emaste Sponsored by: Sandvine Incorporated Notes: svn path=/head/; revision=193096

* Make ipi_cpu() function as intended.Adrian Chadd2009-05-301-1/+4
| | | | | | | | | | | | | | | | | IPI's in Xen are implemented through hypervisor event channels. The MP code creates a pair of IRQs for each base IPI per CPU (one for IPI function dispatch calls, one for IPI bitmap dispatch calls.) Using PCPU_GET() was returning the IRQ of the IPI handler for the current CPU; thus calls to ipi_cpu() were sending itself a message. Instead, looking up the IPI in the target CPU ipi-to-irq map is needed. Note: This doesn't fix Xen SMP (far from it!) but it at least sends IPI's to the right places. Next - sending IPIs..

* Place hostnames and similar information fully under the prison system.Jamie Gritton2009-05-2938-274/+394
| | | | | | | | | | | | | | | | | | | | The system hostname is now stored in prison0, and the global variable "hostname" has been removed, as has the hostname_mtx mutex. Jails may have their own host information, or they may inherit it from the parent/system. The proper way to read the hostname is via getcredhostname(), which will copy either the hostname associated with the passed cred, or the system hostname if you pass NULL. The system hostname can still be accessed directly (and without locking) at prison0.pr_host, but that should be avoided where possible. The "similar information" referred to is domainname, hostid, and hostuuid, which have also become prison parameters and had their associated global variables removed.

* Fix the Xen TOD update when the hypervisor wall clock is nudged.Adrian Chadd2009-05-291-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | The "wall clock" in the current code is actually the hypervisor start time. The time of day is the "start time" plus the hypervisor "uptime". Large enough bumps in the dom0 clock lead to a hypervisor "bump" which is implemented as a bump in the start time, not the uptime. The clock.c routines were reading in the hypervisor start time and then using this as the TOD. This meant that any hypervisor time bump would cause the FreeBSD DomU to set its TOD to the hypervisor start time, rather than the actual TOD. This fix is a bit hacky and some reshuffling should be done later on to clarify what is going on. I've left the wall clock code alone. (The code which updates shadow_tv and shadow_tv_version.) A new routine adds the uptime to the shadow_tv, which is then used to update the TOD. I've included some debugging so it is obvious when the clock is nudged.

| | | | | | | | | | | | | | | | | | | | the last component is a symlink to something that isn't a directory. We introduce a new namei flag, TRAILINGSLASH, which is set by lookup() if the last component is followed by a slash. The trailing slash is then stripped, as before. If the final component is a symlink, lookup() will return to namei(), which will expand the symlink and call lookup() with the new path. When all symlinks have been resolved, lookup() checks if the TRAILINGSLASH flag is set, and if it is, and the vnode it ended up with is not a directory, it returns ENOTDIR.
