[PATCH AUTOSEL 5.6 01/62] kbuild: avoid concurrency issue in parallel building dtbs and dtbs_check

by Sasha Levin

From: Masahiro Yamada <masahiroy(a)kernel.org> [ Upstream commit b5154bf63e5577faaaca1d942df274f7de91dd2a ] 'make dtbs_check' checks the shecma in addition to building *.dtb files, in other words, 'make dtbs_check' is a super-set of 'make dtbs'. So, you do not have to do 'make dtbs dtbs_check', but I want to keep the build system as robust as possible in any use. Currently, 'dtbs' and 'dtbs_check' are independent of each other. In parallel building, two threads descend into arch/*/boot/dts/, one for dtbs and the other for dtbs_check, then end up with building the same DTB simultaneously. This commit fixes the concurrency issue. Otherwise, I see build errors like follows: $ make ARCH=arm64 defconfig $ make -j16 ARCH=arm64 DT_SCHEMA_FILES=Documentation/devicetree/bindings/arm/psci.yaml dtbs dtbs_check <snip> DTC arch/arm64/boot/dts/qcom/sdm845-cheza-r2.dtb DTC arch/arm64/boot/dts/amlogic/meson-gxl-s905x-p212.dtb DTC arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-lite2.dtb DTC arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-lite2.dtb DTC arch/arm64/boot/dts/freescale/imx8mn-evk.dtb DTC arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-one-plus.dtb DTC arch/arm64/boot/dts/zte/zx296718-pcbox.dtb DTC arch/arm64/boot/dts/altera/socfpga_stratix10_socdk.dt.yaml DTC arch/arm64/boot/dts/amlogic/meson-gxl-s905d-p230.dtb DTC arch/arm64/boot/dts/xilinx/zynqmp-zc1254-revA.dtb DTC arch/arm64/boot/dts/allwinner/sun50i-h6-pine-h64.dtb DTC arch/arm64/boot/dts/rockchip/rk3399-gru-scarlet-inx.dtb DTC arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-one-plus.dtb CHECK arch/arm64/boot/dts/altera/socfpga_stratix10_socdk.dt.yaml fixdep: error opening file: arch/arm64/boot/dts/allwinner/.sun50i-h6-orangepi-lite2.dtb.d: No such file or directory make[2]: *** [scripts/Makefile.lib:296: arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-lite2.dtb] Error 2 make[2]: *** Deleting file 'arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-lite2.dtb' make[2]: *** Waiting for unfinished jobs....

Since sparc32 has only 3 page table levels, the PGD and PUD are essentially the same and usage of __nocache_fix() removed the type checking. Use PUD for the consistency and to silence the compiler warning.

[PATCH 1/8] virt: vbox: Fix VBGL_IOCTL_VMMDEV_REQUEST_BIG and _LOG req numbers to match upstream

by Hans de Goede

Until this commit the mainline kernel version (this version) of the vboxguest module contained a bug where it defined VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG using _IOC(_IOC_READ | _IOC_WRITE, 'V', ...) instead of _IO(V, ...) as the out of tree VirtualBox upstream version does. Since the VirtualBox userspace bits are always built against VirtualBox upstream's headers, this means that so far the mainline kernel version of the vboxguest module has been failing these 2 ioctls with -ENOTTY. I guess that VBGL_IOCTL_VMMDEV_REQUEST_BIG is never used causing us to not hit that one and sofar the vboxguest driver has failed to actually log any log messages passed it through VBGL_IOCTL_LOG. This commit changes the VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG defines to match the out of tree VirtualBox upstream vboxguest version, while keeping compatibility with the old wrong request defines so as to not break the kernel ABI in case someone has been using the old request defines.

Hi Greg and everyone, On all kernels, SEV enabled guests hit might_sleep() warnings when a driver (nvme in this case) allocates through the DMA API in a non-blockable context: BUG: sleeping function called from invalid context at mm/vmalloc.c:1710 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 3383, name: fio 2 locks held by fio/3383: #0: ffff93b6a8568348 (&sb->s_type->i_mutex_key#16){+.+.}, at: ext4_file_write_iter+0xa2/0x5d0 #1: ffffffffa52a61a0 (rcu_read_lock){....}, at: hctx_lock+0x1a/0xe0 CPU: 0 PID: 3383 Comm: fio Tainted: G W 5.5.10 #14 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 Call Trace: dump_stack+0x98/0xd5 ___might_sleep+0x175/0x260 __might_sleep+0x4a/0x80 _vm_unmap_aliases+0x45/0x250 vm_unmap_aliases+0x19/0x20 __set_memory_enc_dec+0xa4/0x130 set_memory_decrypted+0x10/0x20 dma_direct_alloc_pages+0x148/0x150 dma_direct_alloc+0xe/0x10 dma_alloc_attrs+0x86/0xc0 dma_pool_alloc+0x16f/0x2b0 nvme_queue_rq+0x878/0xc30 [nvme] __blk_mq_try_issue_directly+0x135/0x200 blk_mq_request_issue_directly+0x4f/0x80 blk_mq_try_issue_list_directly+0x46/0xb0 blk_mq_sched_insert_requests+0x19b/0x2b0 blk_mq_flush_plug_list+0x22f/0x3b0 blk_flush_plug_list+0xd1/0x100 blk_finish_plug+0x2c/0x40 iomap_dio_rw+0x427/0x490 ext4_file_write_iter+0x181/0x5d0 aio_write+0x109/0x1b0 io_submit_one+0x7d0/0xfa0 __x64_sys_io_submit+0xa2/0x280 do_syscall_64+0x5f/0x250 entry_SYSCALL_64_after_hwframe+0x49/0xbe There is a series of patches in Christoph's dma-mapping.git repo in the for-next branch on track for 5.8: 1d659236fb43 dma-pool: scale the default DMA coherent pool size with memory capacity 82fef0ad811f x86/mm: unencrypted non-blocking DMA allocations use coherent pools 2edc5bb3c5cc dma-pool: add pool sizes to debugfs 76a19940bd62 dma-direct: atomic allocations must come from atomic coherent pools 54adadf9b085 dma-pool: dynamically expanding atomic pools c84dc6e68a1d dma-pool: add additional coherent pools to map to gfp mask e860c299ac0d dma-remap: separate DMA atomic pools from direct remap code We'd like to prepare backports to LTS kernels so that our guest images are not modified by us and don't exhibit this issue. They are bigger than we'd like: arch/x86/Kconfig | 1 + drivers/iommu/dma-iommu.c | 5 +- include/linux/dma-direct.h | 2 + include/linux/dma-mapping.h | 6 +- kernel/dma/Kconfig | 6 +- kernel/dma/Makefile | 1 + kernel/dma/direct.c | 56 ++++++-- kernel/dma/pool.c | 264 ++++++++++++++++++++++++++++++++++++ kernel/dma/remap.c | 121 +---------------- 9 files changed, 324 insertions(+), 138 deletions(-) create mode 100644 kernel/dma/pool.c But they apply relatively cleanly to more modern kernels like 5.4. We'd like to backport these all the way to 4.19, however, otherwise guests encounter these bugs. The changes to kernel/dma/remap.c, for example, simply moves code to the new pool.c. But that original code is actually in arch/arm64 in 4.19 and was moved in 5.0: commit 0c3b3171ceccb8830c2bb5adff1b4e9b204c1450 Author: Christoph Hellwig <hch(a)lst.de> Date: Sun Nov 4 20:29:28 2018 +0100 dma-mapping: move the arm64 noncoherent alloc/free support to common code commit f0edfea8ef93ed6cc5f747c46c85c8e53e0798a0 Author: Christoph Hellwig <hch(a)lst.de> Date: Fri Aug 24 10:31:08 2018 +0200 dma-mapping: move the remap helpers to a separate file And there are most certainly more dependencies to get a cleanly applying series to 4.19.123. So the backports could be quite extensive. Peter Gonda <pgonda(a)google.com> is currently handling these and we're looking for advice: should we compile a full list of required backports that would be needed to get a series that would only consist of minor conflicts or is this going to be a non-starter? Thanks!
