* Allow to rename file systems without remounting if it is possible.Pawel Jakub Dawidek2011-10-2411-15/+91
| | | | | | | | | | | | | | | | | | | | | | | It is possible for file systems with 'mountpoint' preperty set to 'legacy' or 'none' - we don't have to change mount directory for them. Currently such file systems are unmounted on rename and not even mounted back. This introduces layering violation, as we need to update 'f_mntfromname' field in statfs structure related to mountpoint (for the dataset we are renaming and all its children). In my opinion it is worth it, as it allow to update FreeBSD in even cleaner way - in ZFS-only configuration root file system is ZFS file system with 'mountpoint' property set to 'legacy'. If root dataset is named system/rootfs, we can snapshot it (system/rootfs@upgrade), clone it (system/oldrootfs), update FreeBSD and if it doesn't boot we can boot back from system/oldrootfs and rename it back to system/rootfs while it is mounted as /. Before it was not possible, because unmounting / was not possible. MFC after: 2 weeks Notes: svn path=/head/; revision=226676

| | | | | | | | | | | | | | | | | of scheduling next run pfsync_bulk_update(), pfsync_bulk_fail() was scheduled. This lead to instant 100% state leak after first bulk update request. - After above fix, it appeared that pfsync_bulk_update() lacks locking. To fix this, sc_bulk_tmo callout was converted to an mtx one. Eventually, all pf/pfsync callouts should be converted to mtx version, since it isn't possible to stop or drain a non-mtx callout without risk of race. - Add comment that callout_stop() in pfsync_clone_destroy() lacks locking. Since pfsync0 can't be destroyed (yet), let it be here. Notes: svn path=/head/; revision=226661
* Fix from r226623 is not sufficient to close all races in pfsync(4).Gleb Smirnoff2011-10-231-40/+59
| | | | | | | | | | | | | | | | | | | | | | | | | The root of problem is re-locking at the end of pfsync_sendout(). Several functions are calling pfsync_sendout() holding pointers to pf data on stack, and these functions expect this data to be consistent. To fix this, the following approach was taken: - The pfsync_sendout() doesn't call ip_output() directly, but enqueues the mbuf on sc->sc_ifp's interfaces queue, that is currently unused. Then pfsync netisr is scheduled. PF_LOCK isn't dropped in pfsync_sendout(). - The netisr runs through queue and ip_output()s packets on it. Apart from fixing race, this also decouples stack, fixing potential issues, that may happen, when sending pfsync(4) packets on input path.

What is being verified by the script: - Does the pool exist? - Does it have bootfs property configured? - Is mountpoint property of the boot dataset set to 'legacy'? Dataset configured in bootfs property has to be mounted to perform more checks: - Does the /boot directory in boot dataset exist? - Is this dataset configured as root file system in /etc/fstab or set in vfs.root.mountfrom variable in /boot/loader.conf? By using zfsboottest tool the script will read all the files in /boot directory using ZFS boot code and calculate their checksums. Then, it will walk /boot directory using find(1) though regular file sytem and also read all the files in /boot directory and calculate their checksums. If any of the files cannot be looked up, read or checksum is invalid it will be reported and booting off of this pool is probably not possible. Some additional checks may be interesting as well. For example if the disks contain proper pmbr and gptzfsboot code or if all expected files in /boot/ are present. When upgrading FreeBSD, one should snapshot datasets that contain operating system, upgrade (install new world and kernel) and use zfsboottest.sh to verify if it will be possible to boot from new configuration. If all is good one should upgrade boot blocks, by eg.: # gpart -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1 If something is wrong, one should rollback datasets and report the problems.
