Resending to CC grekh. Hey everyone, This is the fith iteration of this patch. Per-patch changes are summarized in the individual patches: ChangeLog v4->v5: * added non-functional patch to document devpts_mntget(). Reason for putting this in a separate patch is that it allows you, Linus and Eric, to simply drop it if judged useless. * reverse error handling logic to further simplify * dput() dentry in the non-function patch. This was not really a problem since the following patch included a fix for it. But better to get it right in all individual patches. * I did another rewrite of the problem analysis for posterity in the patch "Subject: [PATCH 2/3 v3] devpts: resolve devpts bind-mounts" and in this cover letter. ChangeLog v3->v4: * small logical simplifications * add test that bind-mounts of /dev/pts/ptmx to locations that do not resolve to a valid slave pty path under the originating devpts mount fail ChangeLog v2->v3: * rewritten commit message to thoroughly analyse the problem for posterity in the patch "Subject: [PATCH 2/3 v3] devpts: resolve devpts bind-mounts" and in this cover letter. * extended selftests to test for correct handling of /dev/pts/ptmx bind-mounts to /dev/ptmx and non-standard devpts mounts such as mount -t devpts devpts /mnt ChangeLog v1->v2: * see individual patches ChangeLog v0->v1: * see individual patches Christian Brauner (4): devpts: hoist out check for DEVPTS_SUPER_MAGIC devpts: resolve devpts bind-mounts devpts: comment devpts_mntget() selftests: add devpts selftests fs/devpts/inode.c | 66 +++-- tools/testing/selftests/Makefile | 1 + tools/testing/selftests/filesystems/.gitignore | 1 + tools/testing/selftests/filesystems/Makefile | 2 +- tools/testing/selftests/filesystems/devpts_pts.c | 313 +++++++++++++++++++++++ 5 files changed, 363 insertions(+), 20 deletions(-) create mode 100644 tools/testing/selftests/filesystems/devpts_pts.c -- 2.15.1 _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/containers
