2  * Access to user system call parameters and results
26  * syscall_get_nr - find what system call a task is executing
30  * If @task is executing a system call or is at system call
31  * tracing about to attempt one, returns the system call number.
32  * If @task is not executing a system call, i.e. it's blocked
36  * system call number can be meaningful.  If the actual arch value
44  * syscall_rollback - roll back registers after an aborted system call
45  * @task:	task of interest, must be in system call exit tracing
48  * It's only valid to call this when @task is stopped for system
51  * the system call from taking place.
54  * system call instruction was a no-op.  The registers containing
55  * the system call number and arguments are as they were before the
56  * system call instruction.  This may not be the same as what the
57  * register state looked like at system call entry tracing.
62  * syscall_get_error - check result of traced system call
66  * Returns 0 if the system call succeeded, or -ERRORCODE if it failed.
69  * from a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
74  * syscall_get_return_value - get the return value of a traced system call
78  * Returns the return value of the successful system call.
82  * from a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
87  * syscall_set_return_value - change the return value of a traced system call
93  * This changes the results of the system call that user mode will see.
94  * If @error is zero, the user sees a successful system call with a
96  * code; the user sees a failed system call with this errno code.
99  * from a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
105  * syscall_get_arguments - extract system call parameter values
112  * Fetches @n arguments to the system call starting with the @i'th argument
117  * entry to a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
118  * It's invalid to call this with @i + @n > 6; we only support system calls
125  * syscall_set_arguments - change system call parameter value
126  * @task:	task of interest, must be in system call entry tracing
132  * Changes @n arguments to the system call starting with the @i'th argument.
137  * entry to a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
138  * It's invalid to call this with @i + @n > 6; we only support system calls
146  * syscall_get_arch - return the AUDIT_ARCH for the current system call
148  * Returns the AUDIT_ARCH_* based on the system call convention in use.
150  * It's only valid to call this when current is stopped on entry to a system
