GEOM ELI may double ask the password during boot. Once at loader time, and
once at init time.
This happens due a module loading bug. By default GEOM ELI caches the
password in the kernel, but without the MODULE_VERSION annotation, the
kernel loads over the kernel module, even if the GEOM ELI was compiled into
the kernel. In this case, the newly loaded module
purges/invalidates/overwrites the GEOM ELI's password cache, which causes
the double asking.
MFC Note: There's a pc98 component to the original submission that is
omitted here due to pc98 removal in head. This part will need to be revived
upon MFC.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
If geom_map fails to find the end of a mapped partition based on a search, it would return the incorrect error message, stating it could not parse the START value

* Just do the buf check early and fail out
* If the offset being searched is:
00110000 00 b5 7e 45 61 e2 76 d3 c1 78 dd 15 95 cd 1f f1 |..~Ea.v..x......|
.. and the match string is '.!/bin/sh'
.. then it'll set the match string[0] to '\0', do a strncmp() against
the read buffer, find it's matching two zero-length strings, and think
that's where to start.

embedded flash stores.
Some devices - notably those with uboot - don't have an
explicit partition table (eg like Redboot's FIS.)
geom_map thus provides an easy way to export the hard-coded
flash layout as geom providers for use by filesystems and
other tools.
It also includes a "search" function which allows for
dynamic creation of partition layouts where the device only
has a single hard-coded partition. For example, if
there is a "kernel+rootfs" partition, a single image can
be created which appends the rootfs after the kernel with
an appropriate search string. geom_map can be told to
search for said search string and create a partition
beginning after it.
