3  * Access to user system call parameters and results
23  * syscall_get_nr - find what system call a task is executing
27  * If @task is executing a system call or is at system call
28  * tracing about to attempt one, returns the system call number.
29  * If @task is not executing a system call, i.e. it's blocked
33  * system call number can be meaningful.  If the actual arch value
41  * syscall_rollback - roll back registers after an aborted system call
42  * @task:	task of interest, must be in system call exit tracing
45  * It's only valid to call this when @task is stopped for system
48  * returned nonzero to prevent the system call from taking place.
51  * system call instruction was a no-op.  The registers containing
52  * the system call number and arguments are as they were before the
53  * system call instruction.  This may not be the same as what the
54  * register state looked like at system call entry tracing.
59  * syscall_get_error - check result of traced system call
63  * Returns 0 if the system call succeeded, or -ERRORCODE if it failed.
66  * from a system call, due to %SYSCALL_WORK_SYSCALL_TRACE or
72  * syscall_get_return_value - get the return value of a traced system call
76  * Returns the return value of the successful system call.
80  * from a system call, due to %SYSCALL_WORK_SYSCALL_TRACE or
86  * syscall_set_return_value - change the return value of a traced system call
92  * This changes the results of the system call that user mode will see.
93  * If @error is zero, the user sees a successful system call with a
95  * code; the user sees a failed system call with this errno code.
98  * from a system call, due to %SYSCALL_WORK_SYSCALL_TRACE or
105  * syscall_get_arguments - extract system call parameter values
110  * Fetches 6 arguments to the system call.  First argument is stored in
114  * entry to a system call, due to %SYSCALL_WORK_SYSCALL_TRACE or
121  * syscall_get_arch - return the AUDIT_ARCH for the current system call
124  * Returns the AUDIT_ARCH_* based on the system call convention in use.
126  * It's only valid to call this when @task is stopped on entry to a system
