The linker can make relocation entries of a symbol which has a value
of zero point to the undefined symbol entry. It is permitted since
when the symbol value is zero as the documentation of the relocation
entry `r_info' field states:
"If the index is STN_UNDEF, the undefined symbol index, the relocation
uses 0 as the symbol value."
The ELF binary does not really have any missing symbols. It is an
optimization as the symbol points to the undefined symbol because its
value is zero.
A typical way to hit this cbfstool limitation is to define an empty
region using the REGION macro in the linker script. Here is an
example if we assume `CONFIG_MY_REGION' is set to 0:
.car.data {
[...]
REGION(my_region, CONFIG_MY_REGION_SIZE)
[...]
}
A region is defined as follow:
#define REGION_SIZE(name) ((size_t)_##name##_size)
#define DECLARE_REGION(name) \
extern u8 _##name[]; \
extern u8 _e##name[]; \
extern u8 _##name##_size[];
So the size of the region is actually the address of the
`_##name##_size' symbol. Therefore, the `_my_region_size' symbol
address is zero and the linker can make the relocation entry of this
symbol point to the undefined symbol index.
In such a situation, cbfstool hits a segmentation fault when it
attempts to relocate the symbol in `parse_elf_to_xip_stage()'
function. We resolves this issue by making cbfstool skips relocation
entries pointing to the undefined symbol similarly to the way it skips
relocation relative to absolute symbols. A symbol which value is zero
can be considered an absolute symbol and therefore should not be
relocated.
Of course, we could argue that we could just prevent the declaration
of an empty region as illustrated in the following example:
.car.data {
[...]
#if CONFIG_MY_REGION_SIZE > 0
REGION(my_region, CONFIG_MY_REGION_SIZE)
#endif
[...]
}
However, this is not a satisfying solution because:
1. It requires to add unnecessary code in the linker script as an empty
region is a valid declaration. Such a workaround requires the code
using it to mark the region symbols as weak symbols to handle the
situation where the region is not defined.
2. There could be other situations which have yet to be uncovered which
would lead the same cbfstool crash.
3. A binary with an empty region is a valid ELF file and cbfstool
should not crash when it is asked to create an eXecute-In-Place stage
out of it.

Revise the Makefile.inc rules for generating FMD parser files.
- lex: If --header-file is supported then the lex (usually flex) should
also support '-o' so we don't need to do redirection (-t).
- yacc: Bison is already required by bincfg and sconfig so we
can change the default parser compiler to Bison. That also
allows us to use -o and --defines to override the output files.
- both: Line directives are only helpful when debugging the scanner and
the parser, so we should remove them to get better git diff
results (-L for lex, -l for bison).
Also regenerated the shipped files with latest version of flex (2.6.4)
and bison (3.8.2).

For x86 eXecute-In-Place (XIP) pre-memory `.data` section support, we
have to use an extra segment as the VMA/LMA of the data is different
than the VMA/LMA of the code.
To support this requirement, this patch makes cbfstool:
1. Allow the load of an ELF with an extra segment
2. Makes add-stage for XIP (cf. parse_elf_to_xip_stage()) write its
content to the output binary.
To prevent the creation of unsuitable binaries, cbfstool verifies that
the LMA addresses of the segments are consecutives.
TEST=XIP pre-memory stages with a `.data` section have the `.data`
section covered by a second segment properly included right after
the code.

To support full 64-bit addresses, there is a new field `ext_lfb_base`
since Linux 4.1. It is unclear, however, how a loader is supposed to
know if the kernel is compatible with this. Filling these previously
reserved bits doesn't hurt, but an old kernel would probably ignore
them and not know that it's handling a clipped, invalid address. So
we play safe, and only allow 64-bit addresses for kernels after the
2.15 version bump of the boot protocol.

SI_BIOS is mostly used to indicate the BIOS region in Intel IFD. Not all
platforms are Intel platforms with an IFD, so revert this change. Also
tooling often depends on names not changing so renaming things should
not be done lightly. The default region should also be in sync with
non-x86 and made systematic across the tree.

Remove the "_DEPRECATED_" tag from ChromeOS diagnostics event and add a
subtype: "ELOG_CROS_DIAGNOSTICS_LOGS" under it.
The data of "ELOG_CROS_DIAGNOSTICS_LOGS" (0x02) contains:
* An uint8_t of subtype code
* Any number of "ChromeOS diagnostics logs" events
Each "ChromeOS diagnostics log" represents the result of one ChromeOS
diagnostics test run. It is stored within an uint8_t raw[3]:
* [23:19] = ELOG_CROS_DIAG_TYPE_*
* [18:16] = ELOG_CROS_DIAG_RESULT_*
* [15:0] = Running time in seconds
Also add support for parsing this event. The parser will first calculate
the number of runs it contains, and try to parse the result one by one.

Note that this size verification is critical as a FIT table only

CL:3825558 changes all vb2_digest and vb2_hash functions to take a new
hwcrypto_allowed argument, to potentially let them try to call the
vb2ex_hwcrypto API for hash calculation. This change will open hardware
crypto acceleration up to all hash calculations in coreboot (most
notably CBFS verification). As part of this change, the
vb2_digest_buffer() function has been removed, so replace existing
instances in coreboot with the newer vb2_hash_calculate() API.
Due to the circular dependency of these changes with vboot, this patch
also needs to update the vboot submodule:

Since there are many identifiers whose name contain "__unused" in
headers of musl libc, introducing a macro which expands "__unused" to
the source of a util may have disastrous effect during its compiling
under a musl-based platform.
However, it is hard to detect musl at build time as musl is notorious
for having explicitly been refusing to add a macro like "__MUSL__" to
announce its own presence.
Using __always_unused and __maybe_unused for everything may be a good
idea. This is how it works in the Linux kernel, so that would at least
make us match some other standard rather than doing our own thing
(especially since the other compiler.h shorthand macros are also
inspired by Linux).

Currently elogtool sub-proccesses flashrom as calling libflashrom
requires a missing function from the previous flashrom release.
Pending a new release of flashrom we must continue to use subprocess.
However the current subprocess wrapper implementation lives in
vboot_reference which is a git sub-module of coreboot. This causes
all sorts of grief keeping a subprocess ABI stable from vboot_reference
when the rest of vboot_reference builds of HEAD of the flashrom tree
(i.e., using unreleased libflashrom functions). In order to not keep
finding ourseleves in a bind between the two separately moving trees
with different build environments, decouple elogtool with its own
mini copy of flashrom subprocess wrapping logic.
Squash in,

This patch adds a new line to `cbfstool print -v` output that records
the overall CBFS verification health of the image. While this info was
already visible from individual fields before, it's nice to have a
one-stop location to see "this is a good image" without having to
carefully parse a lot of output manually.
Also add a few lines to the Makefile that check whether this field is
valid for the final image (it always should be, but hopefully this check
will allow us to catch regressions like the one fixed by CB:64547 sooner
in the future).

The Intel Firmware Interface Table (FIT) is a bit of an annoying outlier
among CBFS files because it gets manipulated by a separate utility
(ifittool) after cbfstool has already added it to the image. This will
break file hashes created for CBFS verification.
This is not actually a problem when booting, since coreboot never
actually loads the FIT from CBFS -- instead, it's only in the image for
use by platform-specific mechanisms that run before coreboot's
bootblock. But having an invalid file hash in the CBFS image is
confusing when you want to verify that the image is correctly built for
verification.
This patch adds a new CBFS file type "intel_fit" which is only used for
the intel_fit (and intel_fit_ts, if applicable) file containing the FIT.
cbfstool will avoid generating and verifying file hashes for this type,
like it already does for the "bootblock" and "cbfs header" types. (Note
that this means that any attempt to use the CBFS API to actually access
this file from coreboot will result in a verification error when CBFS
verification is enabled.)

With LinuxBoot Linux relied on the legacy method of fetching the RSDP
pointer to get ACPI. This uses a more modern approach available since
2018 on the Linux kernel, which involves filling in the zero page.
This method takes precedence over any other method of fetching the
RSDP in Linux (UEFI, Kexec, Legacy/BIOS). Some UEFI zealots are
threatening that legacy code will be removed from Linux so it's best
to already adapt to that possibility.
Tested on Qemu:
- With qemu the RSDP is always in the EBDA, so checking if Linux uses
the provided pointer is better done with a forced bad entry
- With a fake bad pointer Linux correctly does not find RDSP

cb_err_t was meant to be used in place of `enum cb_err` in all

controversial. We should not be arbitrarily using two different

no use cases for serializing enum cb_err at the moment (which would be
the primary reason to typedef a fixed-width integer instead), remove
cb_err_t again for now.

Instead of maintaining another set of byteswapping functions in
cbfstool, this change removes swab.h and replaces it with
bsd/sysincludes.h from commonlib. Callers have been updated to use
be32toh/be64toh/htobe32/htobe64 instead of ntohl/ntohll/htonl/htonll
respectively.

flashmap/fmap.c includes commonlib/bsd/sysincludes.h, which already
includes the necessary header for endian(3) functions (endian.h on
Linux and sys/endian.h on FreeBSD). This also resolves a compilation
error on macOS (tested on 10.5.7), as macOS does not provide endian.h.

The whole point of moving do_cbfs_locate() later (CB:59877) was that it
could use the file size that is actually going to be inserted into CBFS,
rather than the on-disk file size. Unfortunately, after all that work I
forgot to actually make it do that. This patch fixes that.
Since there is no more use case for do_cbfs_locate() having to figure
out the file size on its own, and that generally seems to be a bad idea
(as the original issue shows), also remove that part of it completely
and make the data_size parameter mandatory.

In cbfs_add_component(), the |offset| variable confusingly jumps back
and forth between host address space and flash address space in some
cases. This patch tries to clean that logic up a bit by converting it
to flash address space very early in the function, and then keeping it
that way afterwards. convert() implementations that need the host
address space value should store it in a different variable to reduce
the risk of confusion. This should also fix a tiny issue where
--gen-attribute might have previously encoded the base address as given
in CBFS -- it probably makes more sense to always have it store a
consistent format (i.e. always flash address).
Also revert the unnecessary check for --base-address in
add_topswap_bootblock() that was added in CB:59877. On closer
inspection, the function actually doesn't use the passed in *offset at
all and uses it purely as an out-parameter. So while our current
Makefile does pass --base-address when adding the bootblock, it actually
has no effect and is redundant for the topswap case.

The placement calculation logic in cbfs_add_component() has become quite
a mess, and this patch can only fix that to a limited degree. The
interaction between all the different pathways of how the `offset`
variable can be set and at what point exactly the final placement offset
is decided can get quite convoluted. In particular, one existing problem
is that the offset for a file added with the --align flag is decided
before the convert() function is called, which may change the form (and
thereby the size) of the file again after its location was found --
resulting in a location that ends up being too small, or being unable to
find a location for a file that should fit. This used to be okay under
the assumption that forced alignment should really only be necessary for
use cases like XIP where the file is directly "used" straight from its
location on flash in some way, and those cases can never be compressed
-- however, recent AMD platforms have started using the --align flag to
meet the requirements of their SPI DMA controller and broken this
assumption.
This patch fixes that particular problem and hopefully eliminates a bit
of the convolution by moving the offset decision point in the --align
case after the convert() step. This is safe when the steps in-between
(add_topswap_bootblock() and convert() itself) do not rely on the
location having already been decided by --align before that point. For
the topswap case this is easy, because in practice we always call it
with --base-address (and as far as I can tell that's the only way it was
ever meant to work?) -- so codify that assumption in the function. For
convert() this mostly means that the implementations that do touch the
offset variable (mkstage and FSP) need to ensure they take care of the
alignment themselves. The FSP case is particularly complex so I tried to
rewrite the code in a slightly more straight-forward way and clearly
document the supported cases, which should hopefully make it easier to
see that the offset variable is handled correctly in all of them. For
mkstage the best solution seems to be to only have it touch the offset
variable in the XIP case (where we know compression must be disabled, so
we can rely on it not changing the file size later), and have the extra
space for the stage header directly taken care of by do_cbfs_locate() so
that can happen after convert().
NOTE: This is changing the behavior of `cbfstool add -t fsp` when
neither --base-address nor --xip are passed (e.g. FSP-S). Previously,
cbfstool would implicitly force an alignment of 4K. As far as I can tell
from the comments, this is unnecessary because this binary is loaded
into RAM and CBFS placement does not matter, so I assume this is an
oversight caused by accidentally reusing code that was only meant for
the XIP case.

When using `DECLARE_OPTIONAL_REGION`, it is assumed that
REGION_SIZE(name) == 0 if the region was not defined in the memlayout.
When using non-rmodule stages (i.e., bootblock, romstage, etc), this
assumption holds true, but breaks down in rmodule (i.e., ramstage)
stages.
The rmodule tool is not currently omitting undefined externals from the
relocation table. e.g.,
extern u8 _##name##_size[];
This means that when the rmodule loader runs, it will rewrite the symbol
from 0 (which is the default the linker assumed) to 0 + offset. This is
wrong since the symbol doesn't actually exist. Instead we need to omit
the relocation so it continues to keep the default value of 0.
BUG=b:179699789
TEST=Print out REGION_SIZE(cbfs_cache) in ramstage and verify it is set

Add a new tool that that prints elog events.
The tool, as input, accepts either a file with the RW_ELOG contents, or
if the file is not provided it reads the contents of RW_ELOG by calling
the "flashrom" tool.
The tool is based on "mosys eventlog list"[1]. For the moment it only
supports "list", but future commits will add additional functionality.
This commit also adds missing ELOG defines needed for the tool. These
defines are added with the rest of the ELOG defines, in
include/commonlib/bsd/elog.h
The tool is placed inside util/cbfstool. The rationale behind the
decision, is that this tool shares a lot in common with the other tools
located in cbfstool: vboot dependency, shared files like common.o and
valstr.o, and in spirit is similar to some of the tools located in
cbfstool/.
As an example, you call the tool like the following:
$ elogtool list -f rw_elog_dump.bin

The -a flag was already implemented, it just wasn't exposed for the
add-payload command.
Setting the alignment of the payload will enable using the SPI DMA

Vboot's Makefile is controlled by a ${DEBUG} environment variable.
As the name is very generic, it may be set by accident without any
intention to change the build. Having it set would break reproduci-
bility at least but it also turns out that the hostlib build would
be incomplete so that linking cbfstool fails due to internal calls
to vb2api_fail() which is not built in.

The null-termination of `filetypes` was added after the code was
written, obviously resulting in NULL dereferences. As some more
code has grown around the termination, it's hard to revert the
regression, so let's update the code that still used the array
length.
This fixes commit 7f5f9331d1 (util/cbfstool: fix buffer over-read)
which actually did fix something, but only one path while it broke
two others. We should be careful with fixes, they can always break
something else. Especially when a dumb tool triggered the patching
it seems likely that fewer people looked into related code.

This fixes a hard to debug hang that could occur in any stage, but in
the end it follows simple rules and is easy to fix.
In long mode the 32bit displacement addressing used on 'mov' and 'lea'
instructions is sign-extended. Those instructions can be found using
readelf on the stage and searching for relocation type R_X86_64_32S.
The sign extension is no issue when either running in protected mode or
the code module and thus the address is below 2GiB. If the address is
greater than 2GiB, as usually the case for code in TSEG, the higher
address bits [64:32] are all set to 1 and the effective address is
pointing to memory not paged. Accessing this memory will cause a page
fault, which isn't handled either.
To prevent such problems
- disable R_AMD64_32S relocations in rmodtool
- add comment explaining why it's not allowed
- use the pseudo op movabs, which doesn't use 32bit displacement addressing
- Print a useful error message if such a reloc is present in the code
Fixes a crash in TSEG and when in long mode seen on Intel Sandybridge.

There is a function to fetch the fit table at both the regular address
and the TS address. So reuse that function instead of attempting to
find the TS fit using some pointer aritmetics that is incorrect.

The purpose of this is to eventually move the FIT table out of the
bootblock, generate it separately as a cbfs file and then have the FIT
pointer point to that cbfs file.
TESTED: extracted a FIT table using dd, added it as a cbfs file and see
that the FIT pointer correctly points to it. Also test that trying to
add a non valid FIT cbfs file results in an error.

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).
