Hi, Here are the LSM changes that have been posted in the past. They fix a few bugs in some of the existing security hooks, and add a few more. All of these patches have been discussed on lkml with no known outstanding issues remaining about them.

In response to earlier comments by Christoph, the existing capability check for syslog(2) is moved into the capability security module hook function, and a corresponding dummy security module hook function is defined that provides traditional superuser behavior. The LSM hook is placed in do_syslog rather than sys_syslog so that it is called when either the system call interface or the /proc/kmsg interface is used. SELinux uses this hook to control access to the kernel message ring and to the console log level. include/linux/security.h | 18 ++++++++++++++++++ kernel/printk.c | 7 +++++-- security/capability.c | 10 ++++++++++ security/dummy.c | 8 ++++++++ 4 files changed, 41 insertions(+), 2 deletions(-) ------ ChangeSetat_private, 2003-02-05 14:32:08+11:00, sdsat_private [PATCH] LSM: Add LSM sysctl hook to 2.5.59 This patch adds a LSM sysctl hook for controlling access to sysctl variables to 2.5.59, split out from the lsm-2.5 BitKeeper tree.

These hooks were previously added as of 2.5.27, but the hook calls were subsequently lost as a result of other changes to the code as of 2.5.37.

These changes ensure that security structures for private files will be allocated and freed appropriately. Per Andi Kleen's comments, the patch also renames init_private_file to open_private_file to force updating of all callers, since they will also need to be updated to use close_private_file to avoid a leak of the security structure. Per Christoph Hellwig's comments, the patch also replaces the 'mode' argument with a 'flags' argument, computing the f_mode from the flags, and it explicitly tests f_op prior to dereferencing, as in dentry_open(). fs/exportfs/expfs.c | 5 ++--- fs/file_table.c | 35 +++++++++++++++++++++++++++-------- fs/nfsd/vfs.c | 9 +++------ include/linux/fs.h | 5 ++++- kernel/ksyms.c | 3 ++- 5 files changed, 38 insertions(+), 19 deletions(-) ------ ChangeSetat_private, 2003-01-16 14:23:59-08:00, sdsat_private [PATCH] Replace inode_post_lookup hook with d_instantiate hook This patch removes the security_inode_post_lookup hook entirely and adds a security_d_instantiate hook call to the d_instantiate function and the d_splice_alias function. The inode_post_lookup hook was subject to races since the inode is already accessible through the dcache before it is called, didn't handle filesystems that directly populate the dcache, and wasn't always called in the desired context (e.g. for pipe, shmem, and devpts inodes). The d_instantiate hook enables initialization of the inode security information. This hook is used by SELinux and by DTE to setup the inode security state, and eliminated the need for the inode_precondition function in SELinux. fs/dcache.c | 3 +++ fs/namei.c | 9 +++------ include/linux/security.h | 25 ++++++++++--------------- security/dummy.c | 13 +++++++------ 4 files changed, 23 insertions(+), 27 deletions(-) ------ ChangeSetat_private, 2003-01-16 14:18:05-08:00, sdsat_private [PATCH] Add LSM hook to do_kern_mount This patch adds a security_sb_kern_mount hook call to the do_kern_mount function. This hook enables initialization of the superblock security information of all superblock objects. Placing a hook in do_kern_mount was originally suggested by Al Viro. This hook is used by SELinux to setup the superblock security state and eliminated the need for the superblock_precondition function. fs/super.c | 8 ++++++++ include/linux/security.h | 11 +++++++++++ security/dummy.c | 6 ++++++ 3 files changed, 25 insertions(+) ------ _______________________________________________ linux-security-module mailing list linux-security-moduleat_private http://mail.wirex.com/mailman/listinfo/linux-security-module
