2014-09-02tools: ffs-test: add compatibility code for old kernelsMichal Nazarewicz1-5/+107
If ffs-test is used with a kernel prior to 3.14, which do not support the new descriptors format, it will fail when trying to write the descriptors. Add a function that converts the new descriptors to the legacy ones and use it to retry writing the descriptors using the legacy format. Also add “-l” flag to ffs-test which will cause the tool to never try the new format and instead immediatelly try the legacy one. This should be useful to test whether parsing of the old format still works on given 3.14+ kernel. Signed-off-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2014-09-02tools: ffs-test: convert to new descriptor formatMichal Nazarewicz1-5/+9
Since commit [ac8dde11: “Add flags to descriptors block”] functionfs supports a new, more powerful and extensible, descriptor format. Since ffs-test is probably the first thing users of the functionfs interface see when they start writing functionfs user space daemons, convert it to use the new format thus promoting it.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull namespace updates from Eric Biederman: "This is a bunch of small changes built against 3.16-rc6. The most significant change for users is the first patch which makes setns drmatically faster by removing unneded rcu handling. The next chunk of changes are so that "mount -o remount,.." will not allow the user namespace root to drop flags on a mount set by the system wide root. Aks this forces read-only mounts to stay read-only, no-dev mounts to stay no-dev, no-suid mounts to stay no-suid, no-exec mounts to stay no exec and it prevents unprivileged users from messing with a mounts atime settings. I have included my test case as the last patch in this series so people performing backports can verify this change works correctly. The next change fixes a bug in NFS that was discovered while auditing nsproxy users for the first optimization. Today you can oops the kernel by reading /proc/fs/nfsfs/{servers,volumes} if you are clever with pid namespaces. I rebased and fixed the build of the !CONFIG_NFS_FS case yesterday when a build bot caught my typo. Given that no one to my knowledge bases anything on my tree fixing the typo in place seems more responsible that requiring a typo-fix to be backported as well. The last change is a small semantic cleanup introducing /proc/thread-self and pointing /proc/mounts and /proc/net at it. This prevents several kinds of problemantic corner cases. It is a user-visible change so it has a minute chance of causing regressions so the change to /proc/mounts and /proc/net are individual one line commits that can be trivially reverted. Unfortunately I lost and could not find the email of the original reporter so he is not credited. From at least one perspective this change to /proc/net is a refgression fix to allow pthread /proc/net uses that were broken by the introduction of the network namespace" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: proc: Point /proc/mounts at /proc/thread-self/mounts instead of /proc/self/mounts proc: Point /proc/net at /proc/thread-self/net instead of /proc/self/net proc: Implement /proc/thread-self to point at the directory of the current thread proc: Have net show up under /proc/<tgid>/task/<tid> NFS: Fix /proc/fs/nfsfs/servers and /proc/fs/nfsfs/volumes mnt: Add tests for unprivileged remount cases that have found to be faulty mnt: Change the default remount atime from relatime to the existing value mnt: Correct permission checks in do_remount mnt: Move the test for MNT_LOCK_READONLY from change_mount_flags into do_remount mnt: Only change user settable mount flags in remount namespaces: Use task_lock and not rcu to protect nsproxy
2014-08-09selftests: add memfd/sealing page-pinning testsDavid Herrmann5-1/+450
Setting SEAL_WRITE is not possible if there're pending GUP users. This commit adds selftests for memfd+sealing that use FUSE to create pending page-references. FUSE is very helpful here in that it allows us to delay direct-IO operations for an arbitrary amount of time. This way, we can force the kernel to pin pages and then run our normal selftests.

On IBM powerpc where multiple page size value are supported, current ppc64 and ppc64el distro don't define the PAGE_SIZE variable in /usr/include as this is a dynamic value retrieved by the getpagesize() or sysconf() defined in unistd.h. The PAGE_SIZE variable sounds defined when only one value is supported by the kernel. As such, when the PAGE_SIZE definition doesn't exist system should retrieve the dynamic value.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "Again, ACPICA leads the pack (47 commits), followed by cpufreq (18 commits) and system suspend/hibernation (9 commits). From the new code perspective, the ACPICA update brings ACPI 5.1 to the table, including a new device configuration object called _DSD (Device Specific Data) that will hopefully help us to operate device properties like Device Trees do (at least to some extent) and changes related to supporting ACPI on ARM. Apart from that we have hibernation changes making it use radix trees to store memory bitmaps which should speed up some operations carried out by it quite significantly. We also have some power management changes related to suspend-to-idle (the "freeze" sleep state) support and more preliminary changes needed to support ACPI on ARM (outside of ACPICA). The rest is fixes and cleanups pretty much everywhere. Specifics: - ACPICA update to upstream version 20140724. That includes ACPI 5.1 material (support for the _CCA and _DSD predefined names, changes related to the DMAR and PCCT tables and ARM support among other things) and cleanups related to using ACPICA's header files. A major part of it is related to acpidump and the core code used by that utility. Changes from Bob Moore, David E Box, Lv Zheng, Sascha Wildner, Tomasz Nowicki, Hanjun Guo. - Radix trees for memory bitmaps used by the hibernation core from Joerg Roedel. - Support for waking up the system from suspend-to-idle (also known as the "freeze" sleep state) using ACPI-based PCI wakeup signaling (Rafael J Wysocki). - Fixes for issues related to ACPI button events (Rafael J Wysocki). - New device ID for an ACPI-enumerated device included into the Wildcat Point PCH from Jie Yang. - ACPI video updates related to backlight handling from Hans de Goede and Linus Torvalds. - Preliminary changes needed to support ACPI on ARM from Hanjun Guo and Graeme Gregory. - ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui. - Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros (Rafael J Wysocki). - ACPI-based device hotplug cleanups from Wei Yongjun and Rafael J Wysocki. - Cleanups and improvements related to system suspend from Lan Tianyu, Randy Dunlap and Rafael J Wysocki. - ACPI battery cleanup from Wei Yongjun. - cpufreq core fixes from Viresh Kumar. - Elimination of a deadband effect from the cpufreq ondemand governor and intel_pstate driver cleanups from Stratos Karafotis. - 350MHz CPU support for the powernow-k6 cpufreq driver from Mikulas Patocka. - Fix for the imx6 cpufreq driver from Anson Huang. - cpuidle core and governor cleanups from Daniel Lezcano, Sandeep Tripathy and Mohammad Merajul Islam Molla. - Build fix for the big_little cpuidle driver from Sachin Kamat. - Configuration fix for the Operation Performance Points (OPP) framework from Mark Brown. - APM cleanup from Jean Delvare. - cpupower utility fixes and cleanups from Peter Senna Tschudin, Andrey Utkin, Himangi Saraogi, Rickard Strandqvist, Thomas Renninger" * tag 'pm+acpi-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (118 commits) ACPI / LPSS: add LPSS device for Wildcat Point PCH ACPI / PNP: Replace faulty is_hex_digit() by isxdigit() ACPICA: Update version to 20140724.

2014-08-01mnt: Add tests for unprivileged remount cases that have found to be faultyEric W. Biederman3-0/+260
Kenton Varda <kenton@sandstorm.io> discovered that by remounting a read-only bind mount read-only in a user namespace the MNT_LOCK_READONLY bit would be cleared, allowing an unprivileged user to the remount a read-only mount read-write. Upon review of the code in remount it was discovered that the code allowed nosuid, noexec, and nodev to be cleared. It was also discovered that the code was allowing the per mount atime flags to be changed. The first naive patch to fix these issues contained the flaw that using default atime settings when remounting a filesystem could be disallowed. To avoid this problems in the future add tests to ensure unprivileged remounts are succeeding and failing at the appropriate times. Cc: stable@vger.kernel.org Acked-by: Serge E.

Resolved several minor errors in prepare_config() and made some additional improvements. Earlier, the risk of file stream that was not closed. Misuse of strncpy, and the use of strncmp with strlen that makes it pointless. I also check that sscanf has been successful, otherwise continue to the next line. And minimized the use of magic numbers. This was found using a static code analysis program called cppcheck.

Although we expect some small discrepancies for very large counts, we seem to be able to count up to 64 billion instructions without too much skew, so do so. Also switch to using decimals for the instruction counts. This just makes it easier to visually compare the expected vs actual values, as well as the raw result from instructions.

There is at least one bug in core_busy_loop(), we use r0, but it's not in the clobber list. We were getting away with this it seems but that was luck. It's also fishy to be touching the stack, even if we do it below the stack pointer. It seems we get away with it, but looking at the generated code that may just be luck. So move it into assembler, do all the stack handling by hand. We create a stack frame to save the non-volatiles in, so we can muck around with them.

Currently we ignore errors from our sub Makefiles. We inherited that from the top-level selftests Makefile which aims to build and run as many tests as possible and damn the torpedoes. For the powerpc tests we'd instead like any errors to fail the build, so we can automatically catch build failures. We can achieve the best of both worlds by using -k, which tells make to keep building when it hits an error, but still reports the error.

The lack of such periodic flushing made the tools use more memory than needed, as the reordering was being done only after processing all events.
