I wished there was a way to do this in smaller steps, but with
every line fixed an error somewhere else became visible. Here
is a (probably incomplete) list of the issues:
* Only one set of parentheses was supported. This is a hard
to solve problem without a real parser (one solution is to
use an recursive RE, see below).
* The precedence order was wrong. Might have been adapted just
to give a positive result for the arbitrary state of the tree.
* Numbered match variables (e.g. $1, $2, etc.) are not local.
Calling handle_expressions() recursively once with $1, then
with $2, resulted in using the final $2 after the first
recursive call (garbage, practically).
Also, symbol and expression parsing was mixed, making things
harder to follow.
To remedy the issues:
* Split handle_symbol() out. It is called with whitespace
stripped, to keep the uglier REs in handle_expressions().
* Match balanced parentheses and quotes when splitting
expressions. In this recursive RE
/(\((?:[^\(\)]++|(?-1))*\))/
the `(?-1)` references the outer-most group, thus the whole
expression itself. So it matches a pair of parentheses with
a mix of non-parentheses and the recursive rule itself inside.
This allows us to:
* Order the expression matches according to their precedence
rules. Now we can match `<expr> '||' <expr>` first as we should
and everything else falls into its place.
* Remove the bail-out that silenced the undefined behavior.

Gerrit is able to add reviewers based on entries in the `MAINTAINERS`
file. For inclusion and exclusion matches either paths or regular
expressions can be used. The syntax is described in the header of the
file.
When matching a path, there are two sensible possibilities:
- `path/to/file` matches a file.
- `path/to/dir/` matches a folder including its contents recursively.
- `path/to/dir/*` matches all files in that folder, without recursing
into its subfolders.
The trailing slash in the second example is essential. Without it, only
the directory entry itself matches when, for example, the folder gets
deleted, renamed or its permissions get modified. Reviewers in the list
won't get added to changes of any files or directories below that path.
However, from time to time entries get added without this trailing
slash. Thus, implement a workaround in `maintainers.go` to check, if a
path entry is actually a directory. In such case a trailing slash gets
appended, so that the contents will match, too.
Example: `path/to/dir` will become `path/to/dir/`
Tests:
1. output before and after does not differ
2. manual test of resulting regex when running `maintainers.go`

maintainers.go does not handle globs as described in MAINTAINERS.
Instead of only matching the files inside a directory, it also matches
everything below. Also, a glob used in between (`e.g. path/to/*/dir`)
could lead to matching many more paths unexpectedly.
This is caused by the way paths using globs are converted to regegular
expressions for use with gerrit:
1. The script converts all paths with trailing slash to a path with
trailing glob. That means, a recursive match on a directory gets
converted to match only the files in the directory (at least
according to the documentation - if there wasn't 2).
Example: `path/to/dir/` becomes `path/to/dir/*`
2. When converting the path to a regex, all globs get converted to
prefix matching by replacing the glob by `.*`. Instead of only
matching the files in the directory, everything below matches,
which is a) not what the documentation states and b) the opposite
of what 1. did first.
Example: `path/to/dir/*` becomes `^path/to/dir/.*$`
In sum, this leads to all sorts of issues. Examples:
- `path/*/dir` becomes `^path/.*/dir$`
- `path/to/dir/*` becomes `^path/to/dir/.*$`
- `path/to/*.c` becomes `^path/to/.*\.c$`
This change fixes that behaviour by:
- dropping the wrong conversion from 1. above.
- fixing glob matching by replacing `*` by `[^/]`.
- handling paths with trailing `/` as prefix, as documented.
The change was not split because these changes depend on each other and
splitting would break recursive matching between the commits.
Tests:
1. diffed output before and after is equal (!= the same)
2. manual testing of glob matching

Some of the src/vendorcode/ directories are used to import a whole
codebase from somewhere else which uses a completely different coding
style. For those directories, excluding them from checkpatch makes
sense. However, other directories are simply implementing
vendor-specific extensions that were written by coreboot developers
specifically for coreboot in coreboot's coding style. Those directories
should be covered by checkpatch.
This patch narrows the existing blanket exception of src/vendorcode/ to
the amd, cavium, intel and mediatek directories (which actually include
large amounts of foreign source). The eltan, google and siemens
directories (which seem to contain code specifically written for
coreboot) will now be covered by checkpatch.

With the current version method, it's not possible to determine if
a different version is older or newer than the current version without
digging into the repository and finding the dates for the version
numbers.
This change adds the commit date to the start of the toolchain version
which will let us tell at a glance how old or new the toolchain is.
It's not perfect because multiple toolchain commits can go in on the
same day, but adding the time made the string even longer, and really
doesn't help that much.

The CBFS stage header is part of the file data (not the header) from
CBFS's point of view, which is problematic for verification: in pre-RAM
environments, there's usually not enough scratch space in CBFS_CACHE to
load the full stage into memory, so it must be directly loaded into its
final destination. However, that destination is decided from reading the
stage header. There's no way we can verify the stage header without
loading the whole file and we can't load the file without trusting the
information in the stage header.
To solve this problem, this patch changes the CBFS stage format to move
the stage header out of the file contents and into a separate CBFS
attribute. Attributes are part of the metadata, so they have already
been verified before the file is loaded.
Since CBFS stages are generally only meant to be used by coreboot itself
and the coreboot build system builds cbfstool and all stages together in
one go, maintaining backwards-compatibility should not be necessary. An
older version of coreboot will build the old version of cbfstool and a
newer version of coreboot will build the new version of cbfstool before
using it to add stages to the final image, thus cbfstool and coreboot's
stage loader should stay in sync. This only causes problems when someone
stashes away a copy of cbfstool somewhere and later uses it to try to
extract stages from a coreboot image built from a different revision...
a debugging use-case that is hopefully rare enough that affected users
can manually deal with finding a matching version of cbfstool.
The SELF (payload) format, on the other hand, is designed to be used for
binaries outside of coreboot that may use independent build systems and
are more likely to be added with a potentially stale copy of cbfstool,
so it would be more problematic to make a similar change for SELFs. It
is not necessary for verification either, since they're usually only
used in post-RAM environments and selfload() already maps SELFs to
CBFS_CACHE before loading them to their final destination anyway (so
they can be hashed at that time).

The --alignment flag is currently only handled by cbfstool add, but
there seems little reason to not handle it for all file-adding commands
(the help text actually mentions it for add-stage as well but it doesn't
currently work there). This patch moves the related code (and the
related baseaddress handling) into cbfs_add_component(). As a nice side
effect this allows us to rearrange cbfs_add_component() such that we can
conclusively determine whether we need a hash attribute before trying to
align the file, allowing that code to correctly infer the final header
size even when a hash attribute was implicitly added (for an image built
with CBFS verification enabled).

To support the new CONFIG_CBFS_VERIFICATION feature, cbfstool needs to
update the metadata hash embedded in the bootblock code every time it
adds or removes a CBFS file. This can lead to problems on certain
platforms where the bootblock needs to be specially wrapped in some
platform-specific data structure so that the platform's masked ROM can
recognize it. If that data structure contains any form of hash or
signature of the bootblock code that is checked on every boot, it will
no longer match if cbfstool modifies it after the fact.
In general, we should always try to disable these kinds of features
where possible (they're not super useful anyway). But for platforms
where the hardware simply doesn't allow that, this patch introduces the
concept of "platform fixups" to cbfstool. Whenever cbfstool finds a
metadata hash anchor in a CBFS image, it will run all built-in "fixup
probe" functions on that bootblock to check if it can recognize it as
the wrapper format for a platform known to have such an issue. If so, it
will register a corresponding fixup function that will run whenever it
tries to write back modified data to that bootblock. The function can
then modify any platform-specific headers as necessary.
As first supported platform, this patch adds a fixup for Qualcomm
platforms (specifically the header format used by sc7180), which
recalculates the bootblock body hash originally added by
util/qualcomm/createxbl.py.
(Note that this feature is not intended to support platform-specific
signature schemes like BootGuard directly in cbfstool. For anything that
requires an actual secret key, it should be okay if the user needs to
run a platform-specific signing tool on the final CBFS image before
flashing. This feature is intended for the normal unsigned case (which
on some platforms may be implemented as signing with a well-known key)
so that on a board that is not "locked down" in any way the normal use
case of manipulating an image with cbfstool and then directly flashing
the output file stays working with CONFIG_CBFS_VERIFICATION.)

This patch adds support for the new CONFIG_CBFS_VERIFICATION feature to
cbfstool. When CBFS verification is enabled, cbfstool must automatically
add a hash attribute to every CBFS file it adds (with a handful of
exceptions like bootblock and "header" pseudofiles that are never read
by coreboot code itself). It must also automatically update the metadata
hash that is embedded in the bootblock code. It will automatically find
the metadata hash by scanning the bootblock for its magic number and use
its presence to auto-detect whether CBFS verification is enabled for an
image (and which hash algorithm to use).

cbfstool has always had a CBFS_FILENAME_ALIGN that forces the filename
field to be aligned upwards to the next 16-byte boundary. This was
presumably done to align the file contents (which used to come
immediately after the filename field).
However, this hasn't really worked right ever since we introduced CBFS
attributes. Attributes come between the filename and the contents, so
what this code currently does is fill up the filename field with extra
NUL-bytes to the boundary, and then just put the attributes behind it
with whatever size they may be. The file contents don't end up with any
alignment guarantee and the filename field is just wasting space.
This patch removes the old FILENAME_ALIGN, and instead adds a new
alignment of 4 for the attributes. 4 seems like a reasonable alignment
to enforce since all existing attributes (with the exception of weird
edge cases with the padding attribute) already use sizes divisible by 4
anyway, and the common attribute header fields have a natural alignment
of 4. This means file contents will also have a minimum alignment
guarantee of 4 -- files requiring a larger guarantee can still be added
with the --alignment flag as usual.

In a rare placement edge case when adding a file with alignment
requirements, cbfstool may need to generate a CBFS header that's
slightly larger than it needs to be. The way we do this is by just
increasing the data offset field in the CBFS header until the data falls
to the desired value.
This approach works but it may confuse parsing code in the presence of
CBFS attributes. Normally, the whole area between the attribute offset
and the data offset is filled with valid attributes written back to
back, but when this header expansion occurs the attributes are followed
by some garbage data (usually 0xff). Parsers are resilient against this
but may show unexpected error messages.
This patch solves the problem by moving the attribute offset forwards
together with the data offset, so that the total area used for
attributes doesn't change. Instead, the filename field becomes the
expanded area, which is a closer match to how this worked when it was
originally implemented (before attributes existed) and is less confusing
for parsers since filenames are zero-terminated anyway.

The *location argument to parse_elf_to_stage() is a relic from code all
the way back to 2009 where this function was still used to parse XIP
stages. Nowadays we have a separate parse_elf_to_xip_stage() for that,
so there is no need to heed XIP concerns here. Having a pointer to
represent the location in flash is absolutely irrelevant to a non-XIP
stage, and it is used incorrectly -- we just get lucky that no code path
in cbfstool can currently lead to that value being anything other than
0, otherwise the adjustment of data_start to be no lower than *location
could easily screw things up. This patch removes it.

Memlayout is a mechanism to define memory areas outside the normal
program segment constructed by the linker. Therefore, it generally
doesn't make sense to relocate memlayout symbols when the program is
relocated. They tend to refer to things that are always in one specific
spot, independent of where the program is loaded.
This hasn't really hurt us in the past because the use case we have for
rmodules (ramstage on x86) just happens to not really need to refer to
any memlayout-defined areas at the moment. But that use case may come up
in the future so it's still worth fixing.
This patch declares all memlayout-defined symbols as ABSOLUTE() in the
linker, which is then reflected in the symbol table of the generated
ELF. We can then use that distinction to have rmodtool skip them when
generating the relocation table for an rmodule. (Also rearrange rmodtool
a little to make the primary string table more easily accessible to the
rest of the code, so we can refer to symbol names in debug output.)
A similar problem can come up with userspace unit tests, but we cannot
modify the userspace relocation toolchain (and for unfortunate
historical reasons, it tries to relocate even absolute symbols). We'll
just disable PIC and make those binaries fully static to avoid that
issue.
