These tests were only returning the exit-code of the last command in the
bash script, which would silence failures in commands prior to that.
This patch fixes this. Now these tests will return a non-zero exit code
for any failure when executing these bash scripts.

Adds a third argument to the weekly.sh script, allowing for a different
number of "run threads" (maximum number of tests that can be run at
once) and "compile threads" (threads to allocate to the running of
gem5). This is useful for cases where a high number of compilation
threads is wanted (e.g., 50 or so), but that number of tests running at
once is undesirable.

The Looppoint checkpoint feature is still under-development.
These tests are stalling indefinitely and causing the Weekly tests to

The script run by 'test_replacement_policies.py' was named
'run_replacement_policy_test.py'. This caused the TestLib framework to
fail as any file with the string "test" in it was attempted to parse as
a test. As this is a gem5 Python config file, this caused a failure.
To fix this the file was renamed 'run_replacement_policy.py'.

The current GPU Ruby Random tester tests only test for WT L2 caches,
meaning that some transitions (specific to WB caches) are never
tested. To help ensure better coverage, this commit adds a separate
test that tests WB GPU L2 caches to the per-checkin and nightly
regressions.

The weekly test script was implicitly assuming that no m5out
directory existed in the folder where the script was run.
However, if a prior test ran and failed, it would not clean up
its m5out directory, causing the weekly tests to fail.
This commit resolves this by removing the m5out directory before
trying to run any tests in the weekly script. Moreover, we also
update the weekly script to explicitly remove this m5out directory
at the end of the script.

This patches does the following:
- Adds 'SimpointResource' which encapsulates Simpoint data and
functionality. It replaces the old 'gem5.util.simpoint.SimPoint'
class. Simpoints can be loaded from gem5-resources using the
`obtain_resource` function.
- Adds 'SimpointDirectoryResource'. This inherits form
'SimpointResource'. While 'SimpointResource' takes raw Simpoint data
via parameters, 'SimpointDirectoryResource' assumes the data exists
in files, in a directory.
- Updates the
"configs/example/gem5_library/checkpoints/simpoints-se-checkpoint.py"
and
"configs/example/gem5_library/checkpoints/simpoints-se-restory.py"
example files to utilize this new Simpoint resource classes.
**Note**: While the old "SimPoint" class
("src/python/gem5/util/simpoint.py") is marked as deprecated, it may be
difficult to utilize given updates to the APIs in the gem5 stdlib Cores
and Simulator modules.

This patch allows for the "version" field in the resources.json file to
be `null` (translated to `None` in the Python JSON package) or not
declared. In this case the resources.json file will be used regardless
as to what version the gem5 binary is set. This is useful for testing
purposes.
Tests have been updated to utilize this where possible.

This commit specializes the Resource class into specific sub-types.
The `Resource`, `CustomResource` and `CustomDiskImageResource` classes
have been deprecated in favor of the `AbstractResource` subclasses.
Custom Resources can be created via the resource specialization
constructor. Resources can be obtained via the gem5-resource
infrastructure with the `obtain_resource` function.
Fully implemented:
- DiskImageResource
- BinaryResource
- KernelResource
- BootloaderResource
- FileResource
- DirectoryResource
Partially implemented:
- SimpointResource
- CheckpointResource
While the schema of the resource.json file has changed, efforts have
been made to ensure backwards compatibility is maintained during this
transition.
Tests are included in this commit to verify this feature works as
expected.
**Note:** The Simpoint tests are disabled in this commit, to be
reenabled when Simpoint resource specialization is fully incorporated

When a user ran "tests/compiler-tests.sh" without passing any arguments,
the compiler tests would fail with:
```
scons: Reading SConscript files ...
Error: No existing build directory and no variant for /gem5
```
However, when passed with arguments, such as:
```
./tests/compiler-tests.sh -j6
```
the tests passed.
The fix for this is to merge the "$build_out" and "$build_args" into a
single string when executing the docker. I do not know exactly why this
works, but it does fix the error.

This commit adds the following functions to the `m5` python module:
- setMaxTick(tick) -> None
- getMaxTick() -> int
- getTicksUntilMax() -> int
- scheduleTickExitFromCurrent(tick, exit_string) -> None
- scheduleTickExitAbsolute(tick, exit_string) -> None
Until this patch the only way to set an exit at a particular tick was
via `simulate.run` which would reschedule the maximum tick. This
functionality has been explicity exposed via the new `setMaxTick`
function. However, as this is only rescheduling the maximum tick, it
stops scheduling exits at multiple different ticks.
To get around this problem the `scheduleTickExit` functions have been
added. These allow a user to schedule multiple exit events. The
functions contain a `exit_string` parameter that provides the string
the simulator is to return when the specified tick is met. By default
this string is "Tick exit reached" which is used by the stdlib
Simulator module to declare a new `SCHEDULED_TICK` exit event (Note:
this has been deliberatly kept seperate from the `MAX_TICK` exit event.
This commit serves as an attempt to decouple these are two concepts).
Tests are provided in this patch to ensure these new functions work as
intended.
Additional notes:
- The `simulate` function has been fixed to match the documentation. If
the `num_cycles` is -1 then the maximum ticks is set to MaxTicks.
Otherwise the max ticks is set to `curTicks() + num_cycles`. The
functionality of this function will remain unchanged to the end-user.
- Full integration into the Simulator module is not complete as of this
patch. Users must us the m5 python module to set these exit events.

The nightly tests failed here:
https://jenkins.gem5.org/job/nightly/430/. What seems to have happened
is the ALL/gem5.opt us compiled within the Docker container but then,
for the KVM tests, there is an attempt to recompile on the host, which
causes compilation problems. The safest strategy here is delete the
build directory prior to running the KVM tests.
In latest versions of our test infrastructure, the KVM tests should be
run completely separately (i.e., in different Jenkin's jobs) to avoid
this.

Hi, we are security researchers from the Advanced Research Center at Trellix.
We have began a campaign to patch a widespread bug named CVE-2007-4559.
CVE-2007-4559 is a 15 year old bug in the Python tarfile package. By using
extract() or extractall() on a tarfile object without sanitizing input,
a maliciously crafted .tar file could perform a directory path traversal
attack. We found at least one unsantized extractall() in your codebase
and are providing a patch for you via pull request. The patch essentially
checks to see if all tarfile members will be extracted safely and throws
an exception otherwise. We encourage you to use this patch or your own
solution to secure against CVE-2007-4559.
If you have further questions you may contact us through this
projects lead researcher Kasimir Schulz.
