* Remove the long obsolete ufm driver.Warner Losh2020-08-205-468/+1
| | | | | | | | | | | | | It was a driver for a USB FM tuner that was available in the market in 2002. I wrote the driver in 2003. I've not used it since 2005 or so, so it's time to retire this driver. No userland code ever interfaced to the special device it created. There's no user base: the last bug I received on this driver was in 2004. Relnotes: Yes Notes: svn path=/head/; revision=364432

* zfs: fix EIO accessing dataset after resuming interrupted receiveAlan Somers2020-08-201-1/+1
| | | | | | | | | | | | | | | | | | | | ZFS unmounts a dataset while receiving into it and remounts it afterwards. But if ZFS is resuming an incomplete receive, it screws up and ends up with a dataset that is mounted, but returns EIO for every access. This commit fixes that condition. While the vulnerable code also exists in OpenZFS, the problem is not reproducible there. Apparently OpenZFS doesn't unmount the destination dataset during receive, like FreeBSD does.

* Use pmap_mapbios() to map ACPI tables on amd64 and i386.Mark Johnston2020-08-202-182/+38
| | | | | | | | | | | | | | | | | | | The ACPI table-mapping code used pmap_kenter_temporary() to create mappings, which in turn uses the fixed-size crashdump map. Moreover, the code was not verifying that the table fits in this map, so when mapping large tables we could clobber adjacent mappings. This use of pmap_kenter_temporary() appears to predate support in pmap_mapbios() for creating early mappings, but that restriction no longer applies.

* Add the MSG_TLSAPPDATA flag to indicate "return ENXIO" for non-application TLSRick Macklem2020-08-192-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | data records. The kernel RPC cannot process non-application data records when using TLS. It must to an upcall to a userspace daemon that will call SSL_read() to process them. This patch adds a new flag called MSG_TLSAPPDATA that the kernel RPC can use to tell sorecieve() to return ENXIO instead of a non-application data record, when that is what is at the top of the receive queue. I put the code in #ifdef KERN_TLS/#endif, although it will build without that, so that it is recognized as only useful when KERN_TLS is enabled. The alternative to doing this is to have the kernel RPC re-queue the non-application data message after receiving it, but that seems more complicated and might introduce message ordering issues when there are multiple non-application data records one after another. I do not know what, if any, changes will be required to support TLS1.3. Reviewed by: glebius Differential Revision: https://reviews.freebsd.org/D25923 Notes: svn path=/head/; revision=364409

* TCP: remove special treatment for hardware (ifnet) TLSAndrew Gallatin2020-08-193-301/+21
| | | | | | | | | | | | | | | | | | | | | | | | | Remove most special treatment for ifnet TLS in the TCP stack, except for code to avoid mixing handshakes and bulk data. This code made heroic efforts to send down entire TLS records to NICs. It was added to improve the PCIe bus efficiency of older TLS offload NICs which did not keep state per-session, and so would need to re-DMA the first part(s) of a TLS record if a TLS record was sent in multiple TCP packets or TSOs. Newer TLS offload NICs do not need this feature. At Netflix, we've run extensive QoE tests which show that this feature reduces client quality metrics, presumably because the effort to send TLS records atomically causes the server to both wait too long to send data (leading to buffers running dry), and to send too much data at once (leading to packet loss).

| | | | | | | | | | | | | | | | | | | MOUNT notifies when a filesystem is mounted REMOUNT notifies when a filesystem is mounted again UNMOUNT notifies when a filesystem is unmounted These events are asynchronous to the actual state of the event (though the data is recorded at a time when it is stable). The mount event is reported after the filesystem is mounted. However, in the interim it may be unmounted by another agent. Likewise, umount is called just before the mountpoint is finished tearing down. It may be remounted (or maybe if the process scheduling is wonky and devd gets to run before the last few steps are complete).
