o The em(4) and igb(4) drivers have been updated to version 7.6.1 and 2.5.3 respectively. Among others, this brought support for i219/ i219(2)/ i219(3) hardware found with Skylake generation and newer chipsets as well as an IPv6 workaround for a silicon erratum of 1G server products driven by igb(4). Additionally, the DMA and TSO segment handling of these two drivers has been fixed and cleaned up. o The firmware for qlxgbe(4) has been updated to version 5.4.56, bringing the driver to version 3.10.26. o For 82598, ix(4) incorrectly announced support for SCTP checksum offloading, which has been addressed. o The SCTP stack received several fixes, some of which resolve bugs that were unveiled by PVS-Studio. o A regression preventing the none protocol to be used with lagg(4) has been remedied. o The filemon(4) device received several corrections and improvements. o It is now possible again to use truss(1) with Linux/i386 binaries. o A nullfs(5) vnode(9) leak triggered by the rmdir(1) operation has been plugged. o The filter recursion level of libarchive(5) is now limited to 25 (instead of infinite), fixing a potential crash issue. o Support for mounting linprocfs(5) and linsysfs(5) file systems has been added to the jail(2) framework. o Hyper-V bus and network device drivers have received some fixes. o Both the problems with system hangs when using ZFS caused by VFS(9) fixes and optimizations as well as with the generation of ICMP MTU updates when performing NAT caused by tryfoward optimization have been resolved. Because these two regressions were regarded as showstoppers for 10.3-RELEASE and no fixes could be developed in due time, this was done by reverting the changes in question. o The DIOCKILLSTATES IOCTL of pf(4) now uses the correct source and destination ports when removing states. o Two new commands have been added to the amd64 framebuffer driver of the UEFI boot loader. The first is `gop` (as in Graphics Output Protocol), which allows to diagnose problems with efifb(4) but also to set the current graphics mode on machines employing GOP. With `uga` (as in Universal Graphics Adapter), it is possible to do the same on systems using the UGA protocol, which mainly translates to Apple hardware. The latter change also generally introduced UGA support and currently hardcodes the necessary settings for mid-2007 iMacs (iMac7,1) and late-2007 MacBooks (MacBook3,1). But it is likewise possible to manually supply the necessary information for additional systems. o Four new ddb(8) commands for displaying vmem(9) statistics were added. o Some changes were made to the SSL handling of libfetch. For one, it now falls back to the standard/configured CA store. Second, a double-free error resulting from a failing SSL connection has been resolved. o The SCSI Extended INQUIRY probe case of xpt(4) when an error is returned and a retry is scheduled has been fixed. o Panics in ext2fs(5) resulting from rename(r2) race conditions were removed. o The nvd(4) and nvme(4) drivers received fixes and improvements. o Hangs or panics resulting from misbehaved kernel threads returning from their main function have been fixed. o The unbound(8) resolver now uses the new insecure-lan-zones option instead of listing each AS112 zone separately. o A bug in drm2(4) causing GPU hangs with i945GM has been addressed. o The leap-seconds file updating for ntpd(8) was corrected to also work in non-chroot(2) environments. o On device deallocation, tty(4) now clears the queues. o A freed memory dereference when a devfs(5) directory entry is freed has been fixed.
