Merge tag 'trace-fixes-v4.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "Running tests on other changes, the system locked up due to lots of warnings. It was caused by the stack tracer triggering a warning about using rcu_dereference() when RCU was not watching. This can happen due to the fact that the stack tracer uses the function tracer to check each function, and there are functions that may be called and traced when RCU stopped watching. Namely when a function is called just before going idle or to userspace and after RCU stopped watching that current CPU. The first patch makes sure that RCU is watching when the stack tracer uses RCU. The second patch is to make sure that the stack tracer does not get called by functions in NMI, as it's not NMI safe" * tag 'trace-fixes-v4.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Do not allow stack_tracer to record stack in NMI tracing: Have stack tracer force RCU to be watching

Andrey Ryabinin authored
When the kernel compiled with KASAN=y, GCC adds redzones for each variable on stack. This enlarges function's stack frame and causes: 'warning: the frame size of X bytes is larger than Y bytes' The worst case I've seen for now is following: ../net/wireless/nl80211.c: In function `nl80211_send_wiphy': ../net/wireless/nl80211.c:1731:1: warning: the frame size of 5448 bytes is larger than 2048 bytes [-Wframe-larger-than=] That kind of warning becomes useless with KASAN=y. It doesn't necessarily indicate that there is some problem in the code, thus we should turn it off. (The KASAN=y stack size in increased from 16k to 32k for this reason) Signed-off-by:

Currently a simple program below issues a sendfile(2) system call which takes about 62 days to complete in my test KVM instance. int fd; off_t off = 0; fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644); ftruncate(fd, 2); lseek(fd, 0, SEEK_END); sendfile(fd, fd, &off, 0xfffffff); Now you should not ask kernel to do a stupid stuff like copying 256MB in 2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin should have a way to stop you. We actually do have a check for fatal_signal_pending() in generic_perform_write() which triggers in this path however because we always succeed in writing something before the check is done, we return value > 0 from generic_perform_write() and thus the information about signal gets lost. Fix the problem by doing the signal check before writing anything. That way generic_perform_write() returns -EINTR, the error gets propagated up and the sendfile loop terminates early. Signed-off-by:

Use is_zero_pfn() on pteval only after pte_present() check on pteval (It might be better idea to introduce is_zero_pte() which checks pte_present() first). Otherwise when working on a swap or migration entry and if pte_pfn's result is equal to zero_pfn by chance, we lose user's data in __collapse_huge_page_copy(). So if you're unlucky, the application segfaults and finally you could see below message on exit: BUG: Bad rss-counter state mm:ffff88007f099300 idx:2 val:3 Fixes: ca0984ca ("mm: incorporate zero pages into transparent huge pages") Signed-off-by:

call_usermodehelper_exec_sync() does fork() + wait() with "unignored" SIGCHLD. What we have missed is that this worker thread can have other children previously forked by call_usermodehelper_exec_work() without UMH_WAIT_PROC. If such a child exits in between it becomes a zombie because auto-reaping only works if SIGCHLD is ignored, and nobody can reap it (unless/until this worker thread exits too). Change the !UMH_WAIT_PROC case to use CLONE_PARENT. Note: this is only first step. All PF_KTHREAD tasks, even created by kernel_thread() should have ->parent == kthreadd by default.

The variable err was never initialized, that means we had been checking a garbage value in the for loop. Moreover if the segment is not outside the firmware file then also we have been returning the garbage. Initialize it to 0 so that on success we return the value and no need to check in the for loop also as it is initially 0 and whenever that value changes we have done a break from the loop.

The revert dance could use some explanation: we had stuff fixed in -next, and initially backported one commit to v4.3. Now, turns out we need more fixes, and we could cherry-pick them all without conflicts if we reverted the backported one first. So did that to not have to edit and backport them all. * tag 'drm-intel-fixes-2015-10-16' of git://anongit.freedesktop.org/drm-intel: drm/i915: Add primary plane to mask if it's visible drm/i915: Move sprite/cursor plane disable to intel_sanitize_crtc() drm/i915: Assign hwmode after encoder state readout Revert "drm/i915: Add primary plane to mask if it's visible" drm/i915: Deny wrapping an userptr into a framebuffer drm/i915: Enable DPLL VGA mode before P1/P2 divider write drm/i915: Restore lost DPLL register write on gen2-4 drm/i915: Flush pipecontrol post-sync writes drm/i915: Fix kerneldoc for i915_gem_shrink_all

Currently we do not validate rtas.entry before calling enter_rtas(). This leads to a kernel oops when user space calls rtas system call on a powernv platform (see below). This patch adds code to validate rtas.entry before making enter_rtas() call.

Just one fix from Ilia to resolve various issues that have resulted from buffer eviction. * 'linux-4.3' of git://anongit.freedesktop.org/nouveau/linux-2.6: drm/nouveau/gem: return only valid domain when there's only one

Ilia Mirkin authored
On nv50+, we restrict the valid domains to just the one where the buffer was originally created. However after the buffer is evicted to system memory, we might move it back to a different domain that was not originally valid. When sharing the buffer and retrieving its GEM_INFO data, we still want the domain that will be valid for this buffer in a pushbuf, not the one where it currently happens to be. This resolves fdo#92504 and several others. These are due to suspend evicting all buffers, making it more likely that they temporarily end up in the wrong place.
