This is the new replacement for the existing cortex-strings code which will be replaced in a follow-up commit. We should also be able to use some of the math functions to allow the tests to pass on AArch64 (and other architectures) instead of just x86.

I was debugging why login(1) wasn't working as expected on a minimal MFS_ROOT disk image. This image doesn't have syslogd running so the warnings were lost and I had to use GDB to find out why login(1) was failing (missing PAM libraries) instead of being able to see it in the console output.

UBSan complains about out-of-bounds accesses for zero-length arrays. To avoid this we can use flexible array members. However, the C standard does not allow for structures that only contain flexible array members, so we move the length parameters into that structure too. Split out from D28233.

Before UMA CCBs, all CCBs were of the same size, and could be trivially copied using bcopy(9). Now we have to preserve alloc_flags, otherwise we might end up attempting to free stack-allocated CCB to UMA; we also need to take CCB size into account. This fixes kernel panic which would occur when trying to access a stopped (as in, SCSI START STOP, also "ctladm stop") SCSI device.

|e3bcd07d||mav||July 6, 2021, 3:13 a.m.||nvme(4): Report NPWA before NPWG as stripesize.
New Samsung 980 SSDs report Namespace Preferred Write Alignment of 8 (4KB) and Namespace Preferred Write Granularity of 32 (16KB). My quick tests show that 16KB is a minimal sequential write size when the SSD reaches peak IOPS, so writing much less is very slow. But writing slightly less or slightly more does not change much, so it seems not so much a size granularity as minimum I/O size. Thinking about different stripesize consumers: - Partition alignment should be based on NPWA by definition. - ZFS ashift in part of forcing alignment of all I/Os should also be based on NPWA. In part of forcing size granularity, if really needed, it may be set to NPWG, but too big value can make ZFS too space-inefficient, and the 16KB is actually the biggest supported value there now. - ZFS recordsize/volblocksize could potentially be tuned up toward NPWG to work as I/O size granularity, but enabled compression makes it too fuzzy. And those are normally user-configurable things. - ZFS I/O aggregation code could definitely use Optimal Write Size value and may be NPWG, but we don't have fields in GEOM now to report the minimal and optimal I/O sizes, and even maximal is not reported outside GEOM DISK to be used by ZFS.

We removed sysinstall(8) back in 2011, so this workaround should be long since unnecessary. This workaround can end up breaking cases that are hit in the real world, such as dd'ing a small pre-built disk image to a large partition that you intend to grow on first boot and uses a UFS disk label for / in its /etc/fstab (as the only reliable thing a raw UFS image can reference).
