We're currently measuring the raw second stage loader into PCR 9, but
we're closer to spec if we measure the semi-parsed PE into PCR 4. The
hash that's logged is the same as the hash used for the Authenticode
validation, so refactor shim.c a little to separate out the hash
generation.
|
|
It's desirable to be able to use PCR 7 for all TPM policy on Secure Boot
systems, but right now Shim doesn't record any information about its
configuration or the signature used to launch the second stage loader. Add
support for that.

Rob Clark noticed while, implementing a UEFI like backend on u-boot,
that if a File Handle actually returns a meaningful device path from
DevicePathFromHandle(), we wind up with a horribly wrong device path in
the boot variable. He's right, normal UEFI doesn't return that, which
means FileDevicePath() in our code currently does nothing at all.
Instead of all that, pass in the device's handle, and it'll do what
we're doing after the fact there.

When dir->Read() says bs=0, we shouldn't try to allocate a buffer and
read into it. On edk2 this works because there's an implicit (possibly
accidental) minimum size of one pool list entry that can be allocated,
so you wind up getting (I think) 8 bytes.
When Rob Clark tried to run this under uboot's emulated UEFI
environment, dir->Read() returned 0 and when we passed that to
AllocateZeroPool() less good things happened.
So just check for that case and exit appropriately.

The TCG EFI Protocol Specification for family "2.0" mentions that not all
TPM2 chips may support the EFI_TCG2_EVENT_LOG_FORMAT_TCG_2 (crypto agile)
log format. So instead of always use this log format, the GetCapability()
function should be used to determine which format is supported by the TPM.
For example, the Intel PTT firmware based TPM found in Lenovo Thinkapd X1
Carbon (4th gen), only supports SHA-1 (EFI_TCG2_EVENT_LOG_FORMAT_TCG_1_2)
log format. So a call to GetEventLog() using the crypto agile format was
returning EFI_INVALID_PARAMETER, making tpm_log_event() function to fail.
This was preventing shim to correctly measure the second stage bootloader:
$ tpm2_listpcrs -L 0x04:9
Bank/Algorithm: TPM_ALG_SHA1(0x0004)
PCR_09: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
After passing a supported log format to GetEventLog(), it succeeds and so
shim is able to call the HashLogExtendEvent() EFI function correctly:
$ tpm2_listpcrs -L 0x04:9
Bank/Algorithm: TPM_ALG_SHA1(0x0004)
PCR_09: 07 5a 7e d3 75 64 ad 91 1a 34 17 17 c2 34 10 2b 58 5b de b7

The EFI_TCG2_PROTOCOL.GetCapability() function is used to learn if a TPM2
chip is present. But the protocol capability information is also needed
for other reasons, for example to determine what event log formats are
supported by the firmware.
Take out the GetCapability() call from the tpm2_present() logic and reduce
that function to just checking if a TPM2 chip is available or not, so the
capabilities can later be used to determine the supported TPM log formats.

When measuring data into the TPM and generating events logs, the event
type is set to EV_IPL (0xd), and for TPM1.2 the algorithm will always
be set to SHA-1 (0x4).
So, add some macro-defined constants for these instead of having them
as magic numbers to make the code more readable.

(Note "File off" on sections #3 and #8 on the top one.)
This seems to work fine with edk2's loader and shim's loader, as well as
their Authenticode implementation, and pesign's as well.
While PE loaders seem to be fine with sections with alignments smaller
than PE->OptionalHeader.FileAlignment, MS's signtool.exe does ...
something else with them. I'm not sure what. What it definitely does
*not* do is extend the digest based on their file offset and size.
So just don't allow anything that small, and don't allow anything
smaller than SectionAlignment either, just to be on the safe side.
Since most of our stuff gets stripped into the debuginfo anyway, and
shim has relatively few sections, this should not be a very large
burden.
So just to be clear:
If you have a binary with a section that's not aligned on
PE->OptionalHeader.FileAlignment:
- pesign hashes it to A
- tiano hashes it to A
- shim hashes it to A
- signtool.exe hashes it to B
Because that makes sense.
This patch works around the bug in signtool.exe .

The changes in the openssl headers cause the inclusion of
CrtLibSupport.h eariler than the inclusion of stddef.h, so "offsetof"
was defined twice and this caused the followling build error:
In file included from Cryptlib/Include/openssl/buffer.h:23:0,
from Cryptlib/Include/openssl/x509.h:22,

Cryptlib/Include/CrtLibSupport.h:192:0: note: this is the location of the previous definition
#define offsetof(type, member) ( (int) & ((type*)0) -> member )
We can lower the priority of the gcc include path or just remove the
path, but this might cause problem since the path was introduced on
purpose(*). Instead, including stddef.h first is more feasible.
