[PATCH] drm: avoid spurious EBUSY due to nonblocking atomic modesets

by Daniel Vetter

When doing an atomic modeset with ALLOW_MODESET drivers are allowed to pull in arbitrary other resources, including CRTCs (e.g. when reconfiguring global resources). But in nonblocking mode userspace has then no idea this happened, which can lead to spurious EBUSY calls, both: - when that other CRTC is currently busy doing a page_flip the ALLOW_MODESET commit can fail with an EBUSY - on the other CRTC a normal atomic flip can fail with EBUSY because of the additional commit inserted by the kernel without userspace's knowledge For blocking commits this isn't a problem, because everyone else will just block until all the CRTC are reconfigured. Only thing userspace can notice is the dropped frames without any reason for why frames got dropped. Consensus is that we need new uapi to handle this properly, but no one has any idea what exactly the new uapi should look like. As a stop-gap plug this problem by demoting nonblocking commits which might cause issues by including CRTCs not in the original request to blocking commits. v2: Add comments and a WARN_ON to enforce this only when allowed - we don't want to silently convert page flips into blocking plane updates just because the driver is buggy.

[PATCH v7 1/6] net: introduce helper sendpage_ok() in include/linux/net.h

by Coly Li

The original problem was from nvme-over-tcp code, who mistakenly uses kernel_sendpage() to send pages allocated by __get_free_pages() without __GFP_COMP flag. Such pages don't have refcount (page_count is 0) on tail pages, sending them by kernel_sendpage() may trigger a kernel panic from a corrupted kernel heap, because these pages are incorrectly freed in network stack as page_count 0 pages. This patch introduces a helper sendpage_ok(), it returns true if the checking page, - is not slab page: PageSlab(page) is false. - has page refcount: page_count(page) is not zero All drivers who want to send page to remote end by kernel_sendpage() may use this helper to check whether the page is OK. If the helper does not return true, the driver should try other non sendpage method (e.g. sock_no_sendpage()) to handle the page.

[PATCH v8 0/2] Renovate memcpy_mcsafe with copy_mc_to_{user, kernel}

by Dan Williams

Changes since v7 [1]: - Rebased on v5.8-rc5 to resolve a conflict with commit eb25de276505 ("tools arch: Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy'") [1]: http://lore.kernel.org/r/159408043801.2272533.17485467640602344900.stgit@dw… --- Vishal, since this patch set has experienced unprecedented silence from x86 folks I expect you will need to send it to Linus directly during the merge window. It merges cleanly with recent -next. Thomas, Ingo, Boris, please chime in to save Vishal from that awkwardness. I am only going to be sporadically online for the next few weeks. --- The primary motivation to go touch memcpy_mcsafe() is that the existing benefit of doing slow and careful copies is obviated on newer CPUs. That fact solves the problem of needing to detect machine-check recovery capability. Now the old "mcsafe_key" opt-in to careful copying can be made an opt-out from the default fast copy implementation. The discussion with Linus further made clear that this facility had already lost its x86-machine-check specificity starting with commit 2c89130a56a ("x86/asm/memcpy_mcsafe: Add write-protection-fault handling"). The new changes to not require a "careful copy" further de-emphasizes the role that x86-MCA plays in the implementation to just one more source of recoverable trap during the operation. With the above realizations the name "mcsafe" is no longer accurate and copy_safe() is proposed as its replacement. x86 grows a copy_safe_fast() implementation as a default implementation that is independent of detecting the presence of x86-MCA. --- Dan Williams (2): x86, powerpc: Rename memcpy_mcsafe() to copy_mc_to_{user,kernel}() x86/copy_mc: Introduce copy_mc_generic() arch/powerpc/Kconfig | 2 arch/powerpc/include/asm/string.h | 2 arch/powerpc/include/asm/uaccess.h | 40 +++-- arch/powerpc/lib/Makefile | 2 arch/powerpc/lib/copy_mc_64.S | 4 arch/x86/Kconfig | 2 arch/x86/Kconfig.debug | 2 arch/x86/include/asm/copy_mc_test.h | 75 +++++++++ arch/x86/include/asm/mcsafe_test.h | 75 --------- arch/x86/include/asm/string_64.h | 32 ---- arch/x86/include/asm/uaccess.h | 21 +++ arch/x86/include/asm/uaccess_64.h | 20 -- arch/x86/kernel/cpu/mce/core.c | 8 - arch/x86/kernel/quirks.c | 9 - arch/x86/lib/Makefile | 1 arch/x86/lib/copy_mc.c | 64 ++++++++ arch/x86/lib/copy_mc_64.S | 165 ++++++++++++++++++++ arch/x86/lib/memcpy_64.S | 115 -------------- arch/x86/lib/usercopy_64.c | 21 --- drivers/md/dm-writecache.c | 15 +- drivers/nvdimm/claim.c | 2 drivers/nvdimm/pmem.c | 6 - include/linux/string.h | 9 - include/linux/uaccess.h | 9 + include/linux/uio.h | 10 + lib/Kconfig | 7 + lib/iov_iter.c | 43 +++-- tools/arch/x86/include/asm/mcsafe_test.h | 13 -- tools/arch/x86/lib/memcpy_64.S | 115 -------------- tools/objtool/check.c | 5 - tools/perf/bench/Build | 1 tools/perf/bench/mem-memcpy-x86-64-lib.c | 24 --- tools/testing/nvdimm/test/nfit.c | 48 +++--- .../testing/selftests/powerpc/copyloops/.gitignore | 2 tools/testing/selftests/powerpc/copyloops/Makefile | 6 - .../selftests/powerpc/copyloops/copy_mc_64.S | 1 .../selftests/powerpc/copyloops/memcpy_mcsafe_64.S | 1 37 files changed, 451 insertions(+), 526 deletions(-) rename arch/powerpc/lib/{memcpy_mcsafe_64.S => copy_mc_64.S} (98%) create mode 100644 arch/x86/include/asm/copy_mc_test.h delete mode 100644 arch/x86/include/asm/mcsafe_test.h create mode 100644 arch/x86/lib/copy_mc.c create mode 100644 arch/x86/lib/copy_mc_64.S delete mode 100644 tools/arch/x86/include/asm/mcsafe_test.h delete mode 100644 tools/perf/bench/mem-memcpy-x86-64-lib.c create mode 120000 tools/testing/selftests/powerpc/copyloops/copy_mc_64.S delete mode 120000 tools/testing/selftests/powerpc/copyloops/memcpy_mcsafe_64.S base-commit: 11ba468877bb23f28956a35e896356252d63c983

[PATCH 1/3] drm: Restore driver.preclose() for all to use

by Chris Wilson

An unfortunate sequence of events, but it turns out there is a valid usecase for being able to free/decouple the driver objects before they are freed by the DRM core. In particular, if we have a pointer into a drm core object from inside a driver object, that pointer needs to be nerfed *before* it is freed so that concurrent access (e.g. debugfs) does not following the dangling pointer. The legacy marker was adding in the code movement from drp_fops.c to drm_file.c References: 9acdac68bcdc ("drm: rename drm_fops.c to drm_file.c") Signed-off-by: Chris Wilson <chris(a)chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter(a)intel.com> Cc: Gustavo Padovan <gustavo.padovan(a)collabora.com> Cc: CQ Tang <cq.tang(a)intel.com> Cc: <stable(a)vger.kernel.org> # v4.12+ --- drivers/gpu/drm/drm_file.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/gpu/drm/drm_file.c b/drivers/gpu/drm/drm_file.c index 0ac4566ae3f4..7b4258d6f7cc 100644 --- a/drivers/gpu/drm/drm_file.c +++ b/drivers/gpu/drm/drm_file.c @@ -258,8 +258,7 @@ void drm_file_free(struct drm_file *file) (long)old_encode_dev(file->minor->kdev->devt), atomic_read(&dev->open_count)); - if (drm_core_check_feature(dev, DRIVER_LEGACY) && - dev->driver->preclose) + if (dev->driver->preclose) dev->driver->preclose(dev, file); if (drm_core_check_feature(dev, DRIVER_LEGACY)) -- 2.20.1

[PATCH] x86/boot: avoid relaxable symbols with Clang

by Nick Desaulniers

A recent change to a default value of configuration variable (ENABLE_X86_RELAX_RELOCATIONS OFF -> ON) in LLVM now causes Clang's integrated assembler to emit R_X86_64_GOTPCRELX/R_X86_64_REX_GOTPCRELX relocations. LLD will relax instructions with these relocations based on whether the image is being linked as position independent or not. When not, then LLD will relax these instructions to use absolute addressing mode (R_RELAX_GOT_PC_NOPIC). This causes kernels built with Clang and linked with LLD to fail to boot. Also, the LLVM commit notes that these relocation types aren't supported until binutils 2.26. Since we support binutils 2.23+, avoid the relocations regardless of linker. The proper solution is to build the compressed boot image as position independent. There's a series working its way through code review currently that does that, but it's unlikely to be backported to stable, due to its size. For now, cut a smaller patch that's more likely to be easily picked up into stable, so that we can get our kernels booting again.

[PATCH 4.19] net/mlx5e: Don't support phys switch id if not in switchdev mode

by Saeed Mahameed

From: Roi Dayan <roid(a)mellanox.com> Support for phys switch id ndo added for representors and if we do not have representors there is no need to support it. Since each port return different switch id supporting this block support for creating bond over PFs and attaching to bridge in legacy mode.
