The current sighandler only restores the environment saved before, we

When enabling eMCA in BIOS setting on some platforms.two kind similar
EDAC messages for one address may be received, messages include incomplete
EDAC information from BIOS, such as invalid Machine Check Bank information.
e.g., the following is received on CLX-4S,
EDAC skx MC4: CPU 0: Machine Check Event: 0 Bank 255:940000000000009f
this message should be ignored and avoid to be added into reference file.
otherwise the messaage will affect test result.

The "SRAR DCU" test case failed on a CLX-AP server. It's root caused
that the gcc v8.2.1 optimized out the access to the injected location.
Move the "total" from being a local variable to a global to avoid the
optimization by the compiler. Consequently, it can make sure the poisoned
data is consumed to trigger the machine check recovery process.
Before applying the patch:
run : ./srar_recovery.sh -d
log : The poisoned process can't be killed by kernel automatically. Test fails!
After applying the patch:
run : ./srar_recovery.sh -d
log : ./srar_recovery.sh: line 80: 11650 Broken pipe tail -f trigger --pid=$$
11651 Bus error (core dumped) | victim $1 > log

Currently, kernel can correctly handle/recover a user-space error
page, e.g., set "PG_hwpoison" flag, de-attach the error page from
the address mapping, and kill the related processes if it's a
dirty page. While for some kernel error page, kernel can only set
"PG_hwpoison" flag, and return "-EBUSY" error code for system
request (try to be lucky and not touch the kernel error page in
future). The table below shows the error code mapping from kernel
error code to system call error code of madvise() when handling
an error page.
+--------------------------------------------+
| Kernel error code | System call error code |
|-------------------|------------------------|
| MF_IGNORE[1] | EBUSY |
|-------------------|------------------------|
| MF_FAILED[2] | EBUSY |
|-------------------|------------------------|
| MF_DELAYED[2] | 0 (SUCCESS) |
|-------------------|------------------------|
| MF_RECOVERED[2] | 0 (SUCCESS) |
|--------------------------------------------|
| [1] For reserved/slab kernel error pages. |
| [2] For other error pages. |
+--------------------------------------------+
There isn't an existing system error code more suitable than
"EBUSY" to map "MF_IGNORE". And from the above table, the "EBUSY"
system call error code could indicate that kernel ignores a
reserved kernel error page (expected failure) or fails to handle
an error page (real failure).
The page for "clean-anonymous" sub-test from system call
"mmap(..., MAP_PRIVATE|MAP_ANONYMOUS,...)" is a reserved kernel
zeroed page with copy-on-write mapping which kernel can't recover.
So the "EBUSY" error code for this sub-test indicates an expected
failure when doing hardware poison test.

When mce-test is used along with ltp, the "pipe" will be used
between them. "fsck" will do nothing under this situation
because it is not an interactive terminal environment.
To make mce-test worked for this situation, add a "-p" option to
fix this issue.
For example:
[root@localhost tmp]# fsck.ext4 /dev/sdb1
e2fsck 1.42.11 (09-Jul-2014)
ALLEN: clean, 11/610800 files, 76472/2441216 blocks
[root@localhost tmp]# fsck.ext4 /dev/sdb1 | tee -a tmp
e2fsck 1.42.11 (09-Jul-2014)
e2fsck: need terminal for interactive repairs
[root@localhost tmp]# fsck.ext4 /dev/sdb1 -p | tee -a tmp

tinjpage and ttranshuge can get SIGCHLD(CLD_DUMPED) from their child
processes, but now they only check CLD_KILLED, so tests fail.
This behavior of the kernel might not be wrong, because the defalut

With this patch, we accept SIGCHLD(CLD_DUMPED) as a correct behavior.

Minor improvements:
- added sysctl vm.memory_failure_early_kill=0 in the setup of each
testcase (some testcases change this global parameter, so it's safe
to reset it to 0 to avoid interference between testcases),
- added freeing resources (shmems, semaphores) and unpoisoning

This new design reorganize entire structure of MCE-test. After
applying new structure, MCE-test owns new unified output format
and interface.
In principle, during this change, no functional change. Only some
minor fixes and updates are added, BTW, a few new test cases are
merged such as PFA. Other test cases will be applied after this
change is fused into current MCE-test.

Pay attention, please use this case on the kernel >=2.6.39-rc1.
More detail information please refer the test case itself.
BTW, this case doesn't consider the situation such as duplicate
or missing id because current firmware has bugs. It will be

The addr of write/read_hugepage() is the mapping address of file.
So no matter how many hugepages are mapped, addr will be
the head address of all hugepages.
The avoid of write/read_hugepage() is the address which does not
want to be touched. So it could be the head address of any hugepage.
So addr == avoid in write/read_hugepage() is not equal always except
the avoid is the address of the first hugepage.

This patch adds the testcases for mmap/IPV shared pages.
The purpose of these testcases is as follows:
- We can check whether a process A is killed expectedly when it accesses
the page shared with and hwpoisoned by another process B
(in the late killing case).
- We can check whether a process A is killed at once when another process B
injected hwpoison into the page shared by both of them
(in the early killing case).
ChangeLog:
- Add synchronization code between parent and child process with semaphore.
- Share the common function do_shared() between mmap case and IPV case.
- Add error chack code.

operations with heavy workload and make sure every i-node operation gets
the expected result. In details, it firstly generates a huge directory
hierarchy on the target disk, then it performs unlink operations on this
directory hierarchy and duplicate a copy of the directory, finally it
checks if these two directories are same as expected.

page-poisoning test program is an extension of tinjpage test program with a
multi-process model. It spawns thousands of processes that inject HWPosion
error to various pages simultaneously thru madvise syscall. Then it checks
if these errors get handled correctly, i.e. whether each test process
receives or doesn't receive SIGBUS signal as expected.
In details, page-poisoning is designed to cover all of possible userspace page
types via following two test operations:
- anonymous pages operations.
- file data operations.

The MCE stress test suite is a collection of tools and test scripts, which
intends to achieve stress testing for Linux kernel MCA high level handlers
that include HWPosion page recovery, soft page offline, and so on.
In general, this test suite is designed to do stress testing thru various
test interfaces, i.e. madvise syscall, HWPoison page injector, and APEI
injector (see ACPI4.0 spec). And it's able to support most of popular
Linux File Systems (FS), that is, there is an option for user to specify which
FS type they want the test to be running on.
The MCE stress test suite consists of four parts: test driver, workload
controller, customized workloads, and background workloads.
The main test idea is described as below:
- Test driver launchs various customized workloads to continuously generate
lots of pages with expected page states, Note, all of these workloads know
about their expected results that should not be affected by Linux MCE high
level handlers.
- Then test driver injects MCE errors to these pages thru either madvise
syscall or HWPoison injector or APEI injector. While Linux Kernel handling
these MCE errors, all the workloads continue running normally,
- After long time running, test driver will collect test result of each
workload to see if any unexpected failures happened. In such a way, it can
decide if any bug is found.
- If any system panics or FS corruption happens, that means there must be a
bug. It's the bottom line to decide if test gets pass.
Test driver (a.k.a hwpoison.sh) drives the whole test procedure. It's
responsible for managing test environment, setting up error injection
interface, controlling test progress, launching workloads, injecting page
errors, as well as recordng test logs and reportng test result.
