Hi Eric, Here's another update to my patches for user namespace mounts, based on your for-testing branch. These patches add safeguards necessary to allow unprivileged mounts and update SELinux and Smack to safely handle device-backed mounts from unprivileged users. The v2 posting received very little in the way of feedback, so changes are minimal. I've made a trivial style change to the Smack changes at Casey's request, and I've added Stephen's ack for the SELinux changes. Thanks, Seth Andy Lutomirski (1): fs: Treat foreign mounts as nosuid Seth Forshee (6): block_dev: Support checking inode permissions in lookup_bdev() block_dev: Check permissions towards block device inode when mounting mtd: Check permissions towards mtd block device inode when mounting selinux: Add support for unprivileged mounts from user namespaces userns: Replace in_userns with current_in_userns Smack: Handle labels consistently in untrusted mounts drivers/md/bcache/super.c | 2 +- drivers/md/dm-table.c | 2 +- drivers/mtd/mtdsuper.c | 6 +++++- fs/block_dev.c | 18 +++++++++++++++--- fs/exec.c | 2 +- fs/namespace.c | 13 +++++++++++++ fs/quota/quota.c | 2 +- include/linux/fs.h | 2 +- include/linux/mount.h | 1 + include/linux/user_namespace.h | 6 ++---- kernel/user_namespace.c | 6 +++--- security/commoncap.c | 4 ++-- security/selinux/hooks.c | 25 ++++++++++++++++++++++++- security/smack/smack_lsm.c | 29 +++++++++++++++++++---------- 14 files changed, 89 insertions(+), 29 deletions(-) -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
