cmd: Add bind/unbind commands to bind a device to a driver from the command line

2018-08-21T14:21:37+00:00

In some cases it can be useful to be able to bind a device to a driver from
the command line.
The obvious example is for versatile devices such as USB gadget.
Another use case is when the devices are not yet ready at startup and
require some setup before the drivers are bound (ex: FPGA which bitsream is
fetched from a mass storage or ethernet)

usage example:

bind usb_dev_generic 0 usb_ether
unbind usb_dev_generic 0 usb_ether
or
unbind eth 1

bind /ocp/omap_dwc3@48380000/usb@48390000 usb_ether
unbind /ocp/omap_dwc3@48380000/usb@48390000

test/py: tpm2: switch from 'tpm' to 'tpm2' command

2018-07-28T15:58:08+00:00

While using the 'tpm' command should work on most cases, this test suite
only works with TPMv2 and since the work to make both versions build at
the same time, we might end up having both 'tpm' (TPMv1) and 'tpm2'
(TPMv2) commands available at the same time. Ensure this test suite
always use the right one.

test/py: add test for whitelist of variables while importing environment

2018-07-20T19:55:09+00:00

This tests that the importing of an environment with a specified
whitelist works as intended.

If there are variables passed as parameter to the env import command,
those only should be imported in the current environment.

For each variable passed as parameter, if
 - foo is bar in current env and bar2 in exported env, after importing
 exported env, foo shall be bar2,
 - foo does not exist in current env and foo is bar2 in exported env,
 after importing exported env, foo shall be bar2,
 - foo is bar in current env and does not exist in exported env (but is
 passed as parameter), after importing exported env, foo shall be empty
 ONLY if the -d option is passed to env import, otherwise foo shall be
 bar,

Any variable not passed as parameter should be left untouched.

Two other tests are made to test that size cannot be '-' if the checksum
protection is enabled.

test/py: remove hacks for non-zero RAM base address in tests

2018-07-20T19:55:08+00:00

Some functions have different behaviour when the given address is 0
(assumed to be NULL by the function).

find_ram_base() does not return 0 anymore so it's safe to remove those
offsets.

test/py: return a RAM address different from 0 as it can be interpreted as NULL

2018-07-20T19:55:08+00:00

Some functions test that the given address is not NULL (0) and fail or
have a different behaviour if that's the case (e.g. hexport_r).

Let's make the RAM base address to be not zero by setting it to 2MiB if
that's the case.

2MiB is chosen because it represents the size of an ARM LPAE/v8 section.

vboot: Add FIT_SIGNATURE_MAX_SIZE protection

2018-07-10T20:55:58+00:00

This adds a new config value FIT_SIGNATURE_MAX_SIZE, which controls the
max size of a FIT header's totalsize field. The field is checked before
signature checks are applied to protect from reading past the intended
FIT regions.

This field is not part of the vboot signature so it should be sanity
checked. If the field is corrupted then the structure or string region
reads may have unintended behavior, such as reading from device memory.
A default value of 256MB is set and intended to support most max storage
sizes.

test/py: vboot: Remove stderr redirect from openssl command

2018-07-10T20:50:50+00:00

The openssl command specified in test_with_algo() ultimately ends up
being run by RunAndLog::run(), which uses it to construct a Popen object
with the default shell=False. The stderr redirect in the command is
therefore simply passed to openssl as an argument. With at least openssl
1.1.0f this causes openssl, and therefore test_vboot, to fail with:

  genpkey: Use -help for summary.
  Exit code: 1

Any stderr output ought to be captured & stored in the RunAndLog
object's output field and returned from run() via run_and_log() to
test_with_algo() which then ignores it anyway, so we can drop the
shell-like redirection with no ill effects. With this fix test_vboot now
passes for me.

test/py: hush_if_test: Use open() in place of file()

2018-07-10T20:50:50+00:00

In python 3.x the file() function has been removed. Use open() instead,
which works on both python 2.x & 3.x, and is described as the preferred
method of opening a file by python 2.x documentation anyway.

test/py: fit: Open files as binary files

2018-07-10T20:50:50+00:00

The read_file() function in test_fit is used with files that are not
text files, as well as some that are. It is never used in a way that
requires it to decode text files to characters, so open all files in
binary mode such that read() doesn't attempt to decode characters for
files which are not text files.

Without this test_fit fails on python 3.x when reading an FDT in
run_fit_test() with:

  UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd0 in position
                       0: invalid continuation byte
