Branch: https://github.com/XanClic/qemu.git virtiofs-submounts-v4 Branch: https://git.xanclic.moe/XanClic/qemu.git virtiofs-submounts-v4 Hi, In an effort to cut this cover letter shorter, I’ll defer to the cover letter of v2 linked above concerning the general description of this series, and limit myself to describing the differences from v2: v3: - Patch 7: - Replace specific has_passwordless_sudo() function by a generic has_cmd() function that can check for any shell command whether it works or not - Let this function catch exceptions, too, so if sudo is not present altogether, the test doesn’t fail but is skipped as intended [Eduardo] - (Add has_cmds() to run multiple instances of has_cmd() in a decorator) - Skip the test not only if “sudo -n true” doesn’t work, but also check for ssh-keygen, bash, losetup, mkfs.xfs, and mount, which are some other tools we need that might not be present on the host git-backport-diff against v2: Key: [----] : patches are identical [####] : number of functional differences between upstream/downstream patch [down] : patch is downstream-only The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively 001/7:[----] [--] 'virtiofsd: Check FUSE_SUBMOUNTS' 002/7:[----] [--] 'virtiofsd: Add attr_flags to fuse_entry_param' 003/7:[----] [--] 'meson.build: Check for statx()' 004/7:[----] [--] 'virtiofsd: Add mount ID to the lo_inode key' 005/7:[----] [--] 'virtiofsd: Announce sub-mount points' 006/7:[----] [--] 'tests/acceptance/boot_linux: Accept SSH pubkey' 007/7:[0042] [FC] 'tests/acceptance: Add virtiofs_submounts.py' Max Reitz (7): virtiofsd: Check FUSE_SUBMOUNTS virtiofsd: Add attr_flags to fuse_entry_param meson.build: Check for statx() virtiofsd: Add mount ID to the lo_inode key virtiofsd: Announce sub-mount points tests/acceptance/boot_linux: Accept SSH pubkey tests/acceptance: Add virtiofs_submounts.py meson.build | 16 + tools/virtiofsd/fuse_common.h | 7 + tools/virtiofsd/fuse_lowlevel.h | 5 + tools/virtiofsd/fuse_lowlevel.c | 5 + tools/virtiofsd/helper.c | 1 + tools/virtiofsd/passthrough_ll.c | 117 ++++++- tools/virtiofsd/passthrough_seccomp.c | 1 + tests/acceptance/boot_linux.py | 13 +- tests/acceptance/virtiofs_submounts.py | 321 ++++++++++++++++++ .../virtiofs_submounts.py.data/cleanup.sh | 46 +++ .../guest-cleanup.sh | 30 ++ .../virtiofs_submounts.py.data/guest.sh | 138 ++++++++ .../virtiofs_submounts.py.data/host.sh | 127 +++++++ 13 files changed, 811 insertions(+), 16 deletions(-) create mode 100644 tests/acceptance/virtiofs_submounts.py create mode 100644 tests/acceptance/virtiofs_submounts.py.data/cleanup.sh create mode 100644 tests/acceptance/virtiofs_submounts.py.data/guest-cleanup.sh create mode 100644 tests/acceptance/virtiofs_submounts.py.data/guest.sh create mode 100644 tests/acceptance/virtiofs_submounts.py.data/host.sh -- 2.26.2
