bpf: fix byte order test in test_verifier
We really must check with #if __BYTE_ORDER == XYZ instead of just presence of #ifdef __LITTLE_ENDIAN. I noticed that when actually running this on big endian machine, the latter test resolves to true for user space, same for #ifdef __BIG_ENDIAN. E.g., looking at endian.h from libc, both are also defined there, so we really must test this against __BYTE_ORDER instead for proper insns selection. For the kernel, such checks are fine though e.g. see |

ntb: ntb_test: ensure the link is up before trying to configure the mws
After the link tests, there is a race on one side of the test for
the link coming up. It's possible, in some cases, for the test script
to write to the 'peer_trans' files before the link has come up.
To fix this, we simply use the link event file to ensure both sides
see the link as up before continuning.

bpf: don't zero out the info struct in bpf_obj_get_info_by_fd()
The buffer passed to bpf_obj_get_info_by_fd() should be initialized
to zeros. Kernel will enforce that to guarantee we can safely extend
info structures in the future.
Making the bpf_obj_get_info_by_fd() call in libbpf perform the zeroing
is problematic, however, since some members of the info structures
may need to be initialized by the callers (for instance pointers
to buffers to which kernel is to dump translated and jited images).
Remove the zeroing and fix up the in-tree callers before any kernel
has been released with this code.
As Daniel points out this seems to be the intended operation anyway,

selftests/bpf: subtraction bounds test
There is a bug in the verifier's handling of BPF_SUB: [a,b] - [c,d] yields was [a-c, b-d] rather than the correct [a-d, b-c]. So here is a test which, with the bogus handling, will produce ranges of [0,0] and thus allowed accesses; whereas the correct handling will give a range of [-255, 255] (and hence the right-shift will give a range of [0, 255]) and the accesses will be rejected.

kmod: throttle kmod thread limit
If we reach the limit of modprobe_limit threads running the next request_module() call will fail. The original reason for adding a kill was to do away with possible issues with in old circumstances which would create a recursive series of request_module() calls. We can do better than just be super aggressive and reject calls once we've reached the limit by simply making pending callers wait until the threshold has been reduced, and then throttling them in, one by one. This throttling enables requests over the kmod concurrent limit to be processed once a pending request completes. Only the first item queued up to wait is woken up. The assumption here is once a task is woken it will have no other option to also kick the queue to check if there are more pending tasks -- regardless of whether or not it was successful. By throttling and processing only max kmod concurrent tasks we ensure we avoid unexpected fatal request_module() calls, and we keep memory consumption on module loading to a minimum. With x86_64 qemu, with 4 cores, 4 GiB of RAM it takes the following run time to run both tests: time ./kmod.sh -t 0008 real 0m16.366s user 0m0.883s sys 0m8.916s time ./kmod.sh -t 0009 real 0m50.803s user 0m0.791s sys 0m9.852s Link: http://lkml.kernel.org/r/20170628223155.26472-4-mcgrof@kernel.org Signed-off-by: Luis R.

kmod: add test driver to stress test the module loader
This adds a new stress test driver for kmod: the kernel module loader. The new stress test driver, test_kmod, is only enabled as a module right now. It should be possible to load this as built-in and load tests early (refer to the force_init_test module parameter), however since a lot of test can get a system out of memory fast we leave this disabled for now. Using a system with 1024 MiB of RAM can *easily* get your kernel OOM fast with this test driver. The test_kmod driver exposes API knobs for us to fine tune simple request_module() and get_fs_type() calls. Since these API calls only allow each one parameter a test driver for these is rather simple. Other factors that can help out test driver though are the number of calls we issue and knowing current limitations of each. This exposes configuration as much as possible through userspace to be able to build tests directly from userspace. Since it allows multiple misc devices its will eventually (once we add a knob to let us create new devices at will) also be possible to perform more tests in parallel, provided you have enough memory. We only enable tests we know work as of right now.

If you use these paritions for your rootfs you can change the default test driver used for get_fs_type() by exporting it into your environment. For example of other test defaults you can override refer to kmod.sh allow_user_defaults(). Behind the scenes this is how we fine tune at a test case prior to hitting a trigger to run it: cat /sys/devices/virtual/misc/test_kmod0/config echo -n "2" > /sys/devices/virtual/misc/test_kmod0/config_test_case echo -n "ext4" > /sys/devices/virtual/misc/test_kmod0/config_test_fs echo -n "80" > /sys/devices/virtual/misc/test_kmod0/config_num_threads cat /sys/devices/virtual/misc/test_kmod0/config echo -n "1" > /sys/devices/virtual/misc/test_kmod0/config_num_threads Finally to trigger: echo -n "1" > /sys/devices/virtual/misc/test_kmod0/trigger_config The kmod.sh script uses the above constructs to build different test cases. A bit of interpretation of the current failures follows, first two premises: a) When request_module() is used userspace figures out an optimized version of module order for us. Once it finds the modules it needs, as per depmod symbol dep map, it will finit_module() the respective modules which are needed for the original request_module() request. b) We have an optimization in place whereby if a kernel uses request_module() on a module already loaded we never bother userspace as the module already is loaded. This is all handled by kernel/kmod.c. A few things to consider to help identify root causes of issues: 0) kmod 19 has a broken heuristic for modules being assumed to be built-in to your kernel and will return 0 even though request_module() failed. Upgrade to a newer version of kmod. 1) A get_fs_type() call for "xfs" will request_module() for "fs-xfs", not for "xfs". The optimization in kernel described in b) fails to catch if we have a lot of consecutive get_fs_type() calls. The reason is the optimization in place does not look for aliases. This means two consecutive get_fs_type() calls will bump kmod_concurrent, whereas request_module() will not. This one explanation why test case 0009 fails at least once for get_fs_type(). 2) If a module fails to load --- for whatever reason (kmod_concurrent limit reached, file not yet present due to rootfs switch, out of memory) we have a period of time during which module request for the same name either with request_module() or get_fs_type() will *also* fail to load even if the file for the module is ready. This explains why *multiple* NULLs are possible on test 0009. 3) finit_module() consumes quite a bit of memory. 4) Filesystems typically also have more dependent modules than other modules, its important to note though that even though a get_fs_type() call does not incur additional kmod_concurrent bumps, since userspace loads dependencies it finds it needs via finit_module_fd(), it *will* take much more memory to load a module with a lot of dependencies. Because of 3) and 4) we will easily run into out of memory failures with certain tests. For instance test 0006 fails on qemu with 1024 MiB of RAM. It panics a box after reaping all userspace processes and still not having enough memory to reap.

RTC for 4.13
Subsystem:
- expose non volatile RAM using nvmem instead of open coding in many
drivers. Unfortunately, this option has to be enabled by default to not
break existing users.
- rtctest can now test for cutoff dates, showing when an RTC will start
failing to properly save time and date.
- new RTC registration functions to remove race conditions in drivers
Newly supported RTCs:
- Broadcom STB wake-timer
- Epson RX8130CE
- Maxim IC DS1308
- STMicroelectronics STM32H7
Drivers:
- ds1307: use regmap, use nvmem, more cleanups
- ds3232: temperature reading support
- gemini: renamed to ftrtc010
- m41t80: use CCF to expose the clock
- rv8803: use nvmem
- s3c: many cleanups

test_sysctl: test against PAGE_SIZE for int
Add the following tests to ensure we do not regress:
o Test using a buffer full of space (PAGE_SIZE-1) followed by a
single digit works
o Test using a buffer full of spaces (PAGE_SIZE or over) will fail
As tests increase instead of unloading the module and reloading it we
can just do a shell reset_vals() with a reset to values we know are set
at init on the driver.

test_sysctl: add generic script to expand on tests
This adds a generic script to let us more easily add more tests cases.
Since we really have only two types of tests cases just fold them into
the one file. Each test unit is now identified into its separate
function:
# ./sysctl.sh -l
Test ID list:
TEST_ID x NUM_TEST
TEST_ID: Test ID
NUM_TESTS: Number of recommended times to run the test
0001 x 1 - tests proc_dointvec_minmax()
0002 x 1 - tests proc_dostring()
For now we start off with what we had before, and run only each test
once. We can now watch a test case until it fails:
./sysctl.sh -w 0002
We can also run a test case x number of times, say we want to run a test
case 100 times:
./sysctl.sh -c 0001 100
To run a test case only once, for example:
./sysctl.sh -s 0002
The default settings are specified at the top of sysctl.sh.

test_sysctl: add dedicated proc sysctl test driver
The existing tools/testing/selftests/sysctl/ tests include two test cases, but these use existing production kernel sysctl interfaces. We want to expand test coverage but we can't just be looking for random safe production values to poke at, that's just insane! Instead just dedicate a test driver for debugging purposes and port the existing scripts to use it. This will make it easier for further tests to be added. Subsequent patches will extend our test coverage for sysctl. The stress test driver uses a new license (GPL on Linux, copyleft-next outside of Linux). Linus was fine with this [0] and later due to Ted's and Alans's request ironed out an "or" language clause to use [1] which is already present upstream.

in selftests/bpf, but not the other way around.

linux-kselftest-4.13-rc1-update
This update consists of:
-- TAP13 framework and changes to some tests to convert to TAP13.
Converting kselftest output to standard format will help identify
run to run differences and pin point failures easily. TAP13 format
has been in use for several years and the output is human friendly.
Please find the specification:
https://testanything.org/tap-version-13-specification.html
Credit goes to Tim Bird for recommending TAP13 as a suitable format,
and to Grag KH for kick starting the work with help from Paul Elder
and Alice Ferrazzi
The first phase of the TAp13 conversion is included in this update.
Future updates will include updates to rest of the tests.
-- Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.
-- Kselftest documnetation has been converted to ReST format. Document
now has a new home under Documentation/dev-tools.
-- kselftest_harness.h is now available for general use as a result of
Mickaël Salaün's work.
-- Several fixes to skip and/or fail tests gracefully on older releases.

Credit goes to Tim Bird for recommending TAP13 as a suitable
format, and to Grag KH for kick starting the work with help from
Paul Elder and Alice Ferrazzi
The first phase of the TAp13 conversion is included in this update.
Future updates will include updates to rest of the tests.
- Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.
- Kselftest documnetation has been converted to ReST format. Document
now has a new home under Documentation/dev-tools.
- kselftest_harness.h is now available for general use as a result of
Mickaël Salaün's work.
- Several fixes to skip and/or fail tests gracefully on older
releases"

libnvdimm for 4.13
* Introduce the _flushcache() family of memory copy helpers and use them
for persistent memory write operations on x86. The _flushcache()
semantic indicates that the cache is either bypassed for the copy
operation (movnt) or any lines dirtied by the copy operation are
written back (clwb, clflushopt, or clflush).
* Extend dax_operations with ->copy_from_iter() and ->flush()
operations. These operations and other infrastructure updates allow
all persistent memory specific dax functionality to be pushed into
libnvdimm and the pmem driver directly. It also allows dax-specific
sysfs attributes to be linked to a host device, for example:
/sys/block/pmem0/dax/write_cache
* Add support for the new NVDIMM platform/firmware mechanisms introduced
in ACPI 6.2 and UEFI 2.7. This support includes the v1.2 namespace
label format, extensions to the address-range-scrub command set, new
error injection commands, and a new BTT (block-translation-table)
layout. These updates support inter-OS and pre-OS compatibility.
* Fix a longstanding memory corruption bug in nfit_test.
* Make the pmem and nvdimm-region 'badblocks' sysfs files poll(2)
capable.
* Miscellaneous fixes and small updates across libnvdimm and the nfit
driver.

Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security layer updates from James Morris:
- a major update for AppArmor. From JJ:
* several bug fixes and cleanups
* the patch to add symlink support to securityfs that was floated
on the list earlier and the apparmorfs changes that make use of
securityfs symlinks
* it introduces the domain labeling base code that Ubuntu has been
carrying for several years, with several cleanups applied. And it
converts the current mediation over to using the domain labeling
base, which brings domain stacking support with it. This finally
will bring the base upstream code in line with Ubuntu and provide
a base to upstream the new feature work that Ubuntu carries.
* This does _not_ contain any of the newer apparmor mediation
features/controls (mount, signals, network, keys, ...) that
Ubuntu is currently carrying, all of which will be RFC'd on top
of this.
- Notable also is the Infiniband work in SELinux, and the new file:map
permission. From Paul:
"While we're down to 21 patches for v4.13 (it was 31 for v4.12),
the diffstat jumps up tremendously with over 2k of line changes.
Almost all of these changes are the SELinux/IB work done by
Daniel Jurgens; some other noteworthy changes include a NFS v4.2
labeling fix, a new file:map permission, and reporting of policy
capabilities on policy load"
There's also now genfscon labeling support for tracefs, which was
lost in v4.1 with the separation from debugfs.
- Smack incorporates a safer socket check in file_receive, and adds a
cap_capable call in privilege check.
- TPM as usual has a bunch of fixes and enhancements.
- Multiple calls to security_add_hooks() can now be made for the same
LSM, to allow LSMs to have hook declarations across multiple files.
- IMA now supports different "ima_appraise=" modes (eg. log, fix) from
the boot command line.
