POPF is currently broken -- add tests to catch the error. This results in: [RUN] POPF with VIP set and IF clear from vm86 mode [INFO] Exited vm86 mode due to STI [FAIL] Incorrect return reason (started at eip = 0xd, ended at eip = 0xf) because POPF currently fails to check IF before reporting a pending interrupt. This patch also makes the FAIL message a bit more informative.

| * selftests/x86: Add tests for the STR and SLDT instructionsRicardo Neri2018-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit a9e017d5619eb371460c8e516f4684def62bef3a upstream. The STR and SLDT instructions are not valid when running on virtual-8086 mode and generate an invalid operand exception. These two instructions are protected by the Intel User-Mode Instruction Prevention (UMIP) security feature. In protected mode, if UMIP is enabled, these instructions generate a general protection fault if called from CPL > 0. Linux traps the general protection fault and emulates the instructions sgdt, sidt and smsw; but not str and sldt. These tests are added to verify that the emulation code does not emulate these two instructions but the expected invalid operand exception is seen. Tests fallback to exit with INT3 in case emulation does happen.

| * selftests/x86: Add tests for User-Mode Instruction PreventionRicardo Neri2018-03-22

Certain user space programs that run on virtual-8086 mode may utilize instructions protected by the User-Mode Instruction Prevention (UMIP) security feature present in new Intel processors: SGDT, SIDT and SMSW. In such a case, a general protection fault is issued if UMIP is enabled. When such a fault happens, the kernel traps it and emulates the results of these instructions with dummy values. The purpose of this new test is to verify whether the impacted instructions can be executed without causing such #GP. If no #GP exceptions occur, we expect to exit virtual-8086 mode from INT3. The instructions protected by UMIP are executed in representative use cases: a) displacement-only memory addressing b) register-indirect memory addressing c) results stored directly in operands Unfortunately, it is not possible to check the results against a set of expected values because no emulation will occur in systems that do not have the UMIP feature. Instead, results are printed for verification. A simple verification is done to ensure that results of all tests are identical.

| * test_firmware: fix setting old custom fw path back on exitLuis R. Rodriguez2018-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 65c79230576873b312c3599479c1e42355c9f349 ] The file /sys/module/firmware_class/parameters/path can be used to set a custom firmware path. The fw_filesystem.sh script creates a temporary directory to add a test firmware file to be used during testing, in order for this to work it uses the custom path syfs file and it was supposed to reset back the file on execution exit. The script failed to do this due to a typo, it was using OLD_PATH instead of OLD_FWPATH, since its inception since v3.17. Its not as easy to just keep the old setting, it turns out that resetting an empty setting won't actually do what we want, we need to check if it was empty and set an empty space. Without this we end up having the temporary path always set after we run these tests. Fixes: 0a8adf58475 ("test: add firmware_class loader test") Signed-off-by: Luis R.

| * perf tools: Make perf_event__synthesize_mmap_events() scaleStephane Eranian2018-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 88b897a30c525c2eee6e7f16e1e8d0f18830845e ] This patch significantly improves the execution time of perf_event__synthesize_mmap_events() when running perf record on systems where processes have lots of threads. It just happens that cat /proc/pid/maps support uses a O(N^2) algorithm to generate each map line in the maps file. If you have 1000 threads, then you have necessarily 1000 stacks. For each vma, you need to check if it corresponds to a thread's stack. With a large number of threads, this can take a very long time. I have seen latencies >> 10mn. As of today, perf does not use the fact that a mapping is a stack, therefore we can work around the issue by using /proc/pid/tasks/pid/maps. This entry does not try to map a vma to stack and is thus much faster with no loss of functonality. The proc-map-timeout logic is kept in case users still want some upper limit. In V2, we fix the file path from /proc/pid/tasks/pid/maps to actual /proc/pid/task/pid/maps, tasks -> task. Thanks Arnaldo for catching this.

| * tools build: Add tools tree support for 'make -s'Josh Poimboeuf2018-02-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit e572d0887137acfc53f18175522964ec19d88175 upstream. When doing a kernel build with 'make -s', everything is silenced except the objtool build. That's because the tools tree support for silent builds is some combination of missing and broken. Three changes are needed to fix it: - Makefile: propagate '-s' to the sub-make's MAKEFLAGS variable so the tools Makefiles can see it. - tools/scripts/Makefile.include: fix the tools Makefiles' ability to recognize '-s'. The MAKE_VERSION and MAKEFLAGS checks are copied from the top-level Makefile. This silences the "DESCEND objtool" message. - tools/build/Makefile.build: add support to the tools Build files for recognizing '-s'. Again the MAKE_VERSION and MAKEFLAGS checks are copied from the top-level Makefile. This silences all the object compile/link messages.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit e5dfa3f902b9a642ae8c6997d57d7c41e384a90b upstream. The usbip userspace tools call sprintf()/snprintf() and don't check for the return value which can lead the paths to overflow, truncating the final file in the path. More urgently, GCC 7 now warns that these aren't checked with -Wformat-overflow, and with -Werror enabled in configure.ac, that makes these tools unbuildable. This patch fixes these problems by replacing sprintf() with snprintf() in one place and adding checks for the return value of snprintf().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 2f2d0088eb93db5c649d2a5e34a3800a8a935fc5 upstream. When a client has a USB device attached over IP, the vhci_hcd driver is locally leaking a socket pointer address via the /sys/devices/platform/vhci_hcd/status file (world-readable) and in debug output when "usbip --debug port" is run. Fix it to not leak. The socket pointer address is not used at the moment and it was made visible as a convenient way to find IP address from socket pointer address by looking up /proc/net/{tcp,tcp6}. As this opens a security hole, the fix replaces socket pointer address with sockfd.

This tests that the vsyscall entries do what they're expected to do. It also confirms that attempts to read the vsyscall page behave as expected. If changes are made to the vsyscall code or its memory map handling, running this test in all three of vsyscall=none, vsyscall=emulate, and vsyscall=native are helpful. (Because it's easy, this also compares the vsyscall results to their vDSO equivalents.) Note to KAISER backporters: please test this under all three vsyscall modes. Also, in the emulate and native modes, make sure that test_vsyscall_64 agrees with the command line or config option as to which mode you're in. It's quite easy to mess up the kernel such that native mode accidentally emulates or vice versa. Greg, etc: please backport this to all your Meltdown-patched kernels. It'll help make sure the patches didn't regress vsyscalls.

Instead, change the heuristic to roundup(curr->start, 4096) + 4096, so that we can catch such corner cases and have a better chance to find that specific symbol. It's still just best effort as the real end of the symbol is unknown to us (and could even be at a larger offset than the current range), but better than the current situation. Alexei reported that he recently run into case i) with a JITed eBPF program (these are all page aligned) as the last symbol which wasn't properly shown in the call graph (while other eBPF program symbols in the rb tree were displayed correctly). Since this is a generic issue, lets try to improve the heuristic a bit.

While reading in more than one block (50) of KVP records, the allocation goes per block, but the reads used the total number of allocated records (without resetting the pointer/stream). This causes the records buffer to overrun when the refresh reads more than one block over the previous capacity (e.g. reading more than 100 KVP records whereas the in-memory database was empty before). Fix this by reading the correct number of KVP records from file each time. Signed-off-by: Paul Meyer <Paul.Meyer@microsoft.com> Signed-off-by: Long Li <longli@microsoft.com> Signed-off-by: K. Y.

Also add tests for the empty ("") string, since there have been a couple errors in that handling already. Since we now have real ways that the sysfs write might fail, let's add the appropriate check on the 'echo' lines too.
