Re: [RFC PATCH ghak100 V1 0/2] audit: avoid umount hangs on missing mount

On user and remote filesystems, a forced umount can still hang due to attemting to fetch the fcaps of a mounted filesystem that is no longer available. These two patches take different approaches to address this, one by avoiding the lookup when the MNT_FORCE flag is included, the other by providing a method to filter out auditing specified types of filesystems. This can happen on ceph, cifs, 9p, lustre, fuse (gluster) or NFS. Arguably the better way to address this issue is to disable auditing processes that touch removable filesystems. Please see the github issue tracker https://github.com/linux-audit/audit-kernel/issues/100 Richard Guy Briggs (2): audit: avoid fcaps on MNT_FORCE audit: moar filter PATH records keyed on filesystem magic fs/namei.c | 2 +- fs/namespace.c | 3 +++ include/linux/audit.h | 8 ++++++-- kernel/audit.c | 5 +++-- kernel/audit.h | 2 +- kernel/auditsc.c | 29 ++++++++++++++++++++++++++--- 6 files changed, 40 insertions(+), 9 deletions(-)
