This patchset is for implementing extended attribute support within the POSIX message queue (mqueue) file system. This is needed so that the security.selinux extended attribute can be set via a SELinux named type transition on file inodes created within the filesystem. I needed to write a selinux policy for a set of custom applications that use mqueues for their IPC. The mqueues are created by one application and we needed a way for selinux to enforce which of the other application are able to read/write to each individual queue. Uniquely labelling them based on the application that created them and the filename seemed to be our best solution as it’s an embedded system and we don’t have restorecond to handle any relabeling. This series is a result of feedback from the v2 mqueue patch ( http://marc.info/?l=linux-kernel&m=147855351826081&w=2 ) which duplicated the shmem_initxattrs() function for the mqueue file system. This patcheset creates a common simple_xattr_initxattrs() function that can be used by multiple virtual file systems to handle extended attribute initialization via LSM callback. simple_xattr_initxattrs() is an updated version of shmem_initxattrs(). As part of the this series both shmem and mqueue are updated to use the new common initxattrs function. Changes v3 -> v4: - fix uninitialized variable in mqueue patch (3/3) Changes v2 -> v3: - creates new simple_xattr_initxattrs() function - updates shmem to use new callback function - updates mqueue to use new callback function Changes v1 -> v2: - formatting/commit message David Graziano (3): xattr: add simple initxattrs function shmem: use simple initxattrs callback mqueue: Implement generic xattr support fs/xattr.c | 39 +++++++++++++++++++++++++++++++++++++ include/linux/xattr.h | 3 +++ ipc/mqueue.c | 16 ++++++++++++++++ mm/shmem.c | 53 ++++++++++++--------------------------------------- 4 files changed, 70 insertions(+), 41 deletions(-) -- 1.9.1 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
