* zfs: Fix a pair of bugs in zfs_fhtovp()Mark Johnston2022-10-241-1/+2
| | | | | | | | | | | | | | This cherry-picks upstream ed566bf1cd0bdbf85e8c63c1c119e3d2ef5db1f6 - Add a zfs_exit() call in an error path, otherwise a lock is leaked. - Remove the fid_gen > 1 check. That appears to be Linux-specific: zfsctl_snapdir_fid() sets fid_gen to 0 or 1 depending on whether the snapshot directory is mounted. On FreeBSD it fails, making snapshot dirs inaccessible via NFS.

| | | | | | | | | | | | | | | | New driver to ACPI generic event device, defined in ACPI spec. Some ACPI power button may not work without this. In qemu arm64 with "virt" machine, with ACPI firmware, enable devd check devd message by and invoke following command in qemu monitor (qemu) system_powerdown and make sure some power button input event appear. (setting sysctl hw.acpi.power_button_state=S5 is not work, because ACPI tree does not have \_S5 object.) Reviewed by: andrew, hrs Differential Revision: https://reviews.freebsd.org/D37032
* bridge: default to not filtering L3Kristof Provost2022-10-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Change the default for net.link.bridge.pfil_member and net.link.bridge.pfil_bridge to zero. That is, default to not calling layer 3 firewalls on the bridge or its member interfaces. With either of these enabled the bridge will, during L2 processing, remove the Ethernet header from packets, feed them to L3 firewalls, re-add the Ethernet header and send them out. Not only does this interact very poorly with firewalls which defer packets, or reassemble and refragment IPv6, it also causes considerable confusion for users, because the firewall gets called in unexpected ways. For example, a bridge which contains a bhyve tap and the host's LAN interface. We'd expect traffic between the LAN and bhyve VM to pass, no matter what (layer 3) firewall rules are set on the host. That's not the case as long as pfil_bridge or pfil_member are set. Reviewed by: Zhenlei Huang MFC: never Differential Revision: https://reviews.freebsd.org/D37009

* x86/busdma: Limit reserved pages if low nsegsColin Percival2022-10-221-0/+1
| | | | | | | | | | | | | | | | | | | When bus_dmamap_create is called, if bouncing might be required we reserve enough pages for a maximum-length request, subject to the MAX_BPAGES constraint (32 MB on amd64; 32 MB or 2 MB on i386 depending on the amount of RAM). Since pages used for bouncing are typically non-consecutive, each bounced page will typically constitute a busdma segment; as such, we are unlikely to ever successfully use more pages than the nsegments limit. Limit the number of pages reserved to nsegments. On FreeBSD/Firecracker, this reduces bounce page memory consumption from 32 MB to 512 kB, making VMs with 128 MB of RAM usable.

* Increase the maximum size of the journaled soft-updates journal.Kirk McKusick2022-10-211-1/+0
| | | | | | | | | | | | | | The size of the journaled soft-updates journal should be big enough to hold two minutes of filesystem metadata-update activity. The maximum size of the soft updates journal was set in the 1990s. At the time it was assummed that disk arrays would top out at 16 drives and disk writes per drive would top out at 500 per second. Today's I/O subsystems are considerably bigger and faster than those limits. Thus this delta removes the hard upper limit and lets tunefs(8) and newfs(8) set the upper bound based on the size of the filesystem and its cylinder groups. Sponsored by: The FreeBSD Foundation
