This error could lead to infinite loop when data reconstruction was needed. r226551: Don't mark vdev as healthy too soon, so we won't try to use invalid vdevs. r226552: Never pass NULL block pointer when reading. This is neither expected nor handled by lower layers like vdev_raidz, which uses bp for checksum verification. This bug could lead to NULL pointer reference and resets during boot. r226553: Always pass data size for checksum verification function, as using physical block size declared in bp may not always be what we want. For example in case of gang block header physical block size declared in bp is much larger than SPA_GANGBLOCKSIZE (512 bytes) and checksum calculation failed. This bug could lead to accessing unallocated memory and resets/failures during boot. r226554: Fix missing return when LOADER_GPT_SUPPORT is defined, but LOADER_MBR_SUPPORT is not. r226568: - Correctly read gang header from raidz. - Decompress assembled gang block data if compressed. - Verify checksum of a gang header. - Verify checksum of assembled gang block data. - Verify checksum of uber block. Submitted by: avg r226569: With LOADER_MBR_SUPPORT defined and LOADER_GPT_SUPPORT undefined we would never call disk_openmbr(). Submitted by: avg r226611: - Allow to specify multiple files to check, eg. zfsboottest gpt/system0 gpt/system1 - /boot/kernel/kernel /boot/zfsloader - Instead of printing file's content calculate MD5 hash of the file, so it can be easly compared to the hash calculated via file system. - Some other minor improvements. r226612: Because ZFS boot code was very fragile in the past and real PITA to debug, introduce zfsboottest.sh script that will verify if it will be possible to boot from the given pool. # zfsboottest.sh system Where "system" is pool name of the pool we want to boot from. 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.

Some of the kerberos libraries were not linked properly (missing dependencies), which causes 3rd party applications linking to fail when --as-needed ld flag is used. I also added the --no-undefined ld(1) flag to make sure that there're no missing dependencies.

Add support in the kernel for carrying the new IPv6 destination address and port. Add support to TCP and UDP for IPv6 and fix UDP IPv4 to not change the address in the IP header. Add support for IPv6 forwarding to a non-local destination. Add a regession test uitilizing VIMAGE to check all 20 possible combinations I could think of.
