REGISTER_SECURITY(9)						Security Framework					      REGISTER_SECURITY(9)

register_security - registers a security framework with the kernel SYNOPSIS
int register_security(struct security_operations * ops); ARGUMENTS
ops a pointer to the struct security_options that is to be registered DESCRIPTION
This function allows a security module to register itself with the kernel security subsystem. Some rudimentary checking is done on the ops value passed to this function. You'll need to check first if your LSM is allowed to register its ops by calling security_module_enable(ops). If there is already a security module registered with the kernel, an error will be returned. Otherwise 0 is returned on success. COPYRIGHT

UTRACE_ATTACH_TASK(9)						  utrace core API					     UTRACE_ATTACH_TASK(9)

utrace_attach_task - attach new engine, or look up an attached engine SYNOPSIS
struct utrace_engine * utrace_attach_task(struct task_struct * target, int flags, const struct utrace_engine_ops * ops, void * data); ARGUMENTS
target thread to attach to flags flag bits combined with OR, see below ops callback table for new engine data engine private data pointer DESCRIPTION
The caller must ensure that the target thread does not get freed, i.e. hold a ref or be its parent. It is always safe to call this on current, or on the child pointer in a report_clone callback. For most other cases, it's easier to use utrace_attach_pid instead. UTRACE_ATTACH_CREATE Create a new engine. If UTRACE_ATTACH_CREATE is not specified, you only look up an existing engine already attached to the thread. UTRACE_ATTACH_EXCLUSIVE Attempting to attach a second (matching) engine fails with -EEXIST. UTRACE_ATTACH_MATCH_OPS Only consider engines matching ops. UTRACE_ATTACH_MATCH_DATA Only consider engines matching data. Calls with neither UTRACE_ATTACH_MATCH_OPS nor UTRACE_ATTACH_MATCH_DATA match the first among any engines attached to target. That means that UTRACE_ATTACH_EXCLUSIVE in such a call fails with -EEXIST if there are any engines on target at all. Kernel Hackers Manual 2.6. July 2010 UTRACE_ATTACH_TASK(9)

Hi there, I'm currently writing a program/module which makes use of the Linux Security Modules (LSM), which provide hooks for some security .
