I posted V4 here. https://listman.redhat.com/archives/virtio-fs/2022-January/msg00041.html These will allow us to support SELinux with virtiofs. This will send SELinux context at file creation to server and server can set it on file. Changes since V4 ---------------- - Parse only known current size of fuse_init_in. This will make sure that future extension does not break existing code upon header update. (David Gilbert) - Changed order of one of the patch. It is first patch in series. This will help fix the breakage before header update patch and code remains git bisectable. (David Gilbert) - Changed %lx to %llx at one place. (David Gilbert). Thanks Vivek Vivek Goyal (9): virtiofsd: Fix breakage due to fuse_init_in size change linux-headers: Update headers to v5.17-rc1 virtiofsd: Parse extended "struct fuse_init_in" virtiofsd: Extend size of fuse_conn_info->capable and ->want fields virtiofsd, fuse_lowlevel.c: Add capability to parse security context virtiofsd: Move core file creation code in separate function virtiofsd: Create new file with fscreate set virtiofsd: Create new file using O_TMPFILE and set security context virtiofsd: Add an option to enable/disable security label docs/tools/virtiofsd.rst | 7 + include/standard-headers/asm-x86/kvm_para.h | 1 + include/standard-headers/drm/drm_fourcc.h | 11 + include/standard-headers/linux/ethtool.h | 1 + include/standard-headers/linux/fuse.h | 60 ++- include/standard-headers/linux/pci_regs.h | 142 +++--- include/standard-headers/linux/virtio_gpio.h | 72 +++ include/standard-headers/linux/virtio_i2c.h | 47 ++ include/standard-headers/linux/virtio_iommu.h | 8 +- .../standard-headers/linux/virtio_pcidev.h | 65 +++ include/standard-headers/linux/virtio_scmi.h | 24 + linux-headers/asm-generic/unistd.h | 5 +- linux-headers/asm-mips/unistd_n32.h | 2 + linux-headers/asm-mips/unistd_n64.h | 2 + linux-headers/asm-mips/unistd_o32.h | 2 + linux-headers/asm-powerpc/unistd_32.h | 2 + linux-headers/asm-powerpc/unistd_64.h | 2 + linux-headers/asm-riscv/bitsperlong.h | 14 + linux-headers/asm-riscv/mman.h | 1 + linux-headers/asm-riscv/unistd.h | 44 ++ linux-headers/asm-s390/unistd_32.h | 2 + linux-headers/asm-s390/unistd_64.h | 2 + linux-headers/asm-x86/kvm.h | 16 +- linux-headers/asm-x86/unistd_32.h | 1 + linux-headers/asm-x86/unistd_64.h | 1 + linux-headers/asm-x86/unistd_x32.h | 1 + linux-headers/linux/kvm.h | 17 + tools/virtiofsd/fuse_common.h | 9 +- tools/virtiofsd/fuse_i.h | 7 + tools/virtiofsd/fuse_lowlevel.c | 162 +++++-- tools/virtiofsd/helper.c | 1 + tools/virtiofsd/passthrough_ll.c | 414 ++++++++++++++++-- 32 files changed, 1013 insertions(+), 132 deletions(-) create mode 100644 include/standard-headers/linux/virtio_gpio.h create mode 100644 include/standard-headers/linux/virtio_i2c.h create mode 100644 include/standard-headers/linux/virtio_pcidev.h create mode 100644 include/standard-headers/linux/virtio_scmi.h create mode 100644 linux-headers/asm-riscv/bitsperlong.h create mode 100644 linux-headers/asm-riscv/mman.h create mode 100644 linux-headers/asm-riscv/unistd.h
