This is the foundation for writing ++ tracing engines, which can be loadable kernel modules. ++ </para> ++ ++ <para> ++ The basic actors in <application>utrace</application> are the thread ++ and the tracing engine. A tracing engine is some body of code that ++ calls into the <filename><linux/utrace.h></filename> ++ interfaces, represented by a <structname>struct ++ utrace_engine_ops</structname>. (Usually it's a kernel module, ++ though the legacy <function>ptrace</function> support is a tracing ++ engine that is not in a kernel module.) The interface operates on ++ individual threads (<structname>struct task_struct</structname>). ++ If an engine wants to treat several threads as a group, that is up ++ to its higher-level code. ++ </para> ++ ++ <para> ++ Tracing begins by attaching an engine to a thread, using ++ <function>utrace_attach_task</function> or ++ <function>utrace_attach_pid</function>. If successful, it returns a ++ pointer that is the handle used in all other calls. ++ </para> ++ ++ </sect1> ++ ++ <sect1 id="callbacks"><title>Events and Callbacks</title> ++ ++ <para> ++ An attached engine does nothing by default. An engine makes something ++ happen by requesting callbacks via <function>utrace_set_events</function> ++ and poking the thread with <function>utrace_control</function>. ++ The synchronization issues related to these two calls ++ are discussed further below in <xref linkend="teardown"/>. ++ </para> ++ ++ <para> ++ Events are specified using the macro ++ <constant>UTRACE_EVENT(<replaceable>type</replaceable>)</constant>. ++ Each event type is associated with a callback in <structname>struct ++ utrace_engine_ops</structname>. A tracing engine can leave unused ++ callbacks <constant>NULL</constant>. The only callbacks required ++ are those used by the event flags it sets. ++ </para> ++ ++ <para> ++ Many engines can be attached to each thread. When a thread has an ++ event, each engine gets a callback if it has set the event flag for ++ that event type. For most events, engines are called in the order they ++ attached. Engines that attach after the event has occurred do not get ++ callbacks for that event. This includes any new engines just attached ++ by an existing engine's callback function. Once the sequence of ++ callbacks for that one event has completed, such new engines are then ++ eligible in the next sequence that starts when there is another event. ++ </para> ++ ++ <para> ++ Event reporting callbacks have details particular to the event type, ++ but are all called in similar environments and have the same ++ constraints. Callbacks are made from safe points, where no locks ++ are held, no special resources are pinned (usually), and the ++ user-mode state of the thread is accessible. So, callback code has ++ a pretty free hand. But to be a good citizen, callback code should ++ never block for long periods. It is fine to block in ++ <function>kmalloc</function> and the like, but never wait for i/o or ++ for user mode to do something. If you need the thread to wait, use ++ <constant>UTRACE_STOP</constant> and return from the callback ++ quickly. When your i/o finishes or whatever, you can use ++ <function>utrace_control</function> to resume the thread. ++ </para> ++ ++ <para> ++ The <constant>UTRACE_EVENT(SYSCALL_ENTRY)</constant> event is a special ++ case. While other events happen in the kernel when it will return to ++ user mode soon, this event happens when entering the kernel before it ++ will proceed with the work requested from user mode. Because of this ++ difference, the <function>report_syscall_entry</function> callback is ++ special in two ways. For this event, engines are called in reverse of ++ the normal order (this includes the <function>report_quiesce</function> ++ call that precedes a <function>report_syscall_entry</function> call). ++ This preserves the semantics that the last engine to attach is called ++ "closest to user mode"--the engine that is first to see a thread's user ++ state when it enters the kernel is also the last to see that state when ++ the thread returns to user mode. For the same reason, if these ++ callbacks use <constant>UTRACE_STOP</constant> (see the next section), ++ the thread stops immediately after callbacks rather than only when it's ++ ready to return to user mode; when allowed to resume, it will actually ++ attempt the system call indicated by the register values at that time. ++ </para> ++ ++ </sect1> ++ ++ <sect1 id="safely"><title>Stopping Safely</title> ++ ++ <sect2 id="well-behaved"><title>Writing well-behaved callbacks</title> ++ ++ <para> ++ Well-behaved callbacks are important to maintain two essential ++ properties of the interface. The first of these is that unrelated ++ tracing engines should not interfere with each other. If your engine's ++ event callback does not return quickly, then another engine won't get ++ the event notification in a timely manner. The second important ++ property is that tracing should be as noninvasive as possible to the ++ normal operation of the system overall and of the traced thread in ++ particular. That is, attached tracing engines should not perturb a ++ thread's behavior, except to the extent that changing its user-visible ++ state is explicitly what you want to do. (Obviously some perturbation ++ is unavoidable, primarily timing changes, ranging from small delays due ++ to the overhead of tracing, to arbitrary pauses in user code execution ++ when a user stops a thread with a debugger for examination.) Even when ++ you explicitly want the perturbation of making the traced thread block, ++ just blocking directly in your callback has more unwanted effects. For ++ example, the <constant>CLONE</constant> event callbacks are called when ++ the new child thread has been created but not yet started running; the ++ child can never be scheduled until the <constant>CLONE</constant> ++ tracing callbacks return. (This allows engines tracing the parent to ++ attach to the child.) If a <constant>CLONE</constant> event callback ++ blocks the parent thread, it also prevents the child thread from ++ running (even to process a <constant>SIGKILL</constant>). If what you ++ want is to make both the parent and child block, then use ++ <function>utrace_attach_task</function> on the child and then use ++ <constant>UTRACE_STOP</constant> on both threads. A more crucial ++ problem with blocking in callbacks is that it can prevent ++ <constant>SIGKILL</constant> from working. A thread that is blocking ++ due to <constant>UTRACE_STOP</constant> will still wake up and die ++ immediately when sent a <constant>SIGKILL</constant>, as all threads ++ should. Relying on the <application>utrace</application> ++ infrastructure rather than on private synchronization calls in event ++ callbacks is an important way to help keep tracing robustly ++ noninvasive. ++ </para> ++ ++ </sect2> ++ ++ <sect2 id="UTRACE_STOP"><title>Using <constant>UTRACE_STOP</constant></title> ++ ++ <para> ++ To control another thread and access its state, it must be stopped ++ with <constant>UTRACE_STOP</constant>. This means that it is ++ stopped and won't start running again while we access it. When a ++ thread is not already stopped, <function>utrace_control</function> ++ returns <constant>-EINPROGRESS</constant> and an engine must wait ++ for an event callback when the thread is ready to stop. The thread ++ may be running on another CPU or may be blocked. When it is ready ++ to be examined, it will make callbacks to engines that set the ++ <constant>UTRACE_EVENT(QUIESCE)</constant> event bit. To wake up an ++ interruptible wait, use <constant>UTRACE_INTERRUPT</constant>. ++ </para> ++ ++ <para> ++ As long as some engine has used <constant>UTRACE_STOP</constant> and ++ not called <function>utrace_control</function> to resume the thread, ++ then the thread will remain stopped. <constant>SIGKILL</constant> ++ will wake it up, but it will not run user code. When the stop is ++ cleared with <function>utrace_control</function> or a callback ++ return value, the thread starts running again. ++ (See also <xref linkend="teardown"/>.) ++ </para> ++ ++ </sect2> ++ ++ </sect1> ++ ++ <sect1 id="teardown"><title>Tear-down Races</title> ++ ++ <sect2 id="SIGKILL"><title>Primacy of <constant>SIGKILL</constant></title> ++ <para> ++ Ordinarily synchronization issues for tracing engines are kept fairly ++ straightforward by using <constant>UTRACE_STOP</constant>. You ask a ++ thread to stop, and then once it makes the ++ <function>report_quiesce</function> callback it cannot do anything else ++ that would result in another callback, until you let it with a ++ <function>utrace_control</function> call. This simple arrangement ++ avoids complex and error-prone code in each one of a tracing engine's ++ event callbacks to keep them serialized with the engine's other ++ operations done on that thread from another thread of control. ++ However, giving tracing engines complete power to keep a traced thread ++ stuck in place runs afoul of a more important kind of simplicity that ++ the kernel overall guarantees: nothing can prevent or delay ++ <constant>SIGKILL</constant> from making a thread die and release its ++ resources. To preserve this important property of ++ <constant>SIGKILL</constant>, it as a special case can break ++ <constant>UTRACE_STOP</constant> like nothing else normally can. This ++ includes both explicit <constant>SIGKILL</constant> signals and the ++ implicit <constant>SIGKILL</constant> sent to each other thread in the ++ same thread group by a thread doing an exec, or processing a fatal ++ signal, or making an <function>exit_group</function> system call. A ++ tracing engine can prevent a thread from beginning the exit or exec or ++ dying by signal (other than <constant>SIGKILL</constant>) if it is ++ attached to that thread, but once the operation begins, no tracing ++ engine can prevent or delay all other threads in the same thread group ++ dying. ++ </para> ++ </sect2> ++ ++ <sect2 id="reap"><title>Final callbacks</title> ++ <para> ++ The <function>report_reap</function> callback is always the final event ++ in the life cycle of a traced thread. Tracing engines can use this as ++ the trigger to clean up their own data structures. The ++ <function>report_death</function> callback is always the penultimate ++ event a tracing engine might see; it's seen unless the thread was ++ already in the midst of dying when the engine attached. Many tracing ++ engines will have no interest in when a parent reaps a dead process, ++ and nothing they want to do with a zombie thread once it dies; for ++ them, the <function>report_death</function> callback is the natural ++ place to clean up data structures and detach. To facilitate writing ++ such engines robustly, given the asynchrony of ++ <constant>SIGKILL</constant>, and without error-prone manual ++ implementation of synchronization schemes, the ++ <application>utrace</application> infrastructure provides some special ++ guarantees about the <function>report_death</function> and ++ <function>report_reap</function> callbacks. It still takes some care ++ to be sure your tracing engine is robust to tear-down races, but these ++ rules make it reasonably straightforward and concise to handle a lot of ++ corner cases correctly. ++ </para> ++ </sect2> ++ ++ <sect2 id="refcount"><title>Engine and task pointers</title> ++ <para> ++ The first sort of guarantee concerns the core data structures ++ themselves. <structname>struct utrace_engine</structname> is ++ a reference-counted data structure. While you hold a reference, an ++ engine pointer will always stay valid so that you can safely pass it to ++ any <application>utrace</application> call. Each call to ++ <function>utrace_attach_task</function> or ++ <function>utrace_attach_pid</function> returns an engine pointer with a ++ reference belonging to the caller. You own that reference until you ++ drop it using <function>utrace_engine_put</function>. There is an ++ implicit reference on the engine while it is attached. So if you drop ++ your only reference, and then use ++ <function>utrace_attach_task</function> without ++ <constant>UTRACE_ATTACH_CREATE</constant> to look up that same engine, ++ you will get the same pointer with a new reference to replace the one ++ you dropped, just like calling <function>utrace_engine_get</function>. ++ When an engine has been detached, either explicitly with ++ <constant>UTRACE_DETACH</constant> or implicitly after ++ <function>report_reap</function>, then any references you hold are all ++ that keep the old engine pointer alive. ++ </para> ++ ++ <para> ++ There is nothing a kernel module can do to keep a <structname>struct ++ task_struct</structname> alive outside of ++ <function>rcu_read_lock</function>. When the task dies and is reaped ++ by its parent (or itself), that structure can be freed so that any ++ dangling pointers you have stored become invalid. ++ <application>utrace</application> will not prevent this, but it can ++ help you detect it safely. By definition, a task that has been reaped ++ has had all its engines detached. All ++ <application>utrace</application> calls can be safely called on a ++ detached engine if the caller holds a reference on that engine pointer, ++ even if the task pointer passed in the call is invalid. All calls ++ return <constant>-ESRCH</constant> for a detached engine, which tells ++ you that the task pointer you passed could be invalid now. Since ++ <function>utrace_control</function> and ++ <function>utrace_set_events</function> do not block, you can call those ++ inside a <function>rcu_read_lock</function> section and be sure after ++ they don't return <constant>-ESRCH</constant> that the task pointer is ++ still valid until <function>rcu_read_unlock</function>. The ++ infrastructure never holds task references of its own. Though neither ++ <function>rcu_read_lock</function> nor any other lock is held while ++ making a callback, it's always guaranteed that the <structname>struct ++ task_struct</structname> and the <structname>struct ++ utrace_engine</structname> passed as arguments remain valid ++ until the callback function returns. ++ </para> ++ ++ <para> ++ The common means for safely holding task pointers that is available to ++ kernel modules is to use <structname>struct pid</structname>, which ++ permits <function>put_pid</function> from kernel modules. When using ++ that, the calls <function>utrace_attach_pid</function>, ++ <function>utrace_control_pid</function>, ++ <function>utrace_set_events_pid</function>, and ++ <function>utrace_barrier_pid</function> are available. ++ </para> ++ </sect2> ++ ++ <sect2 id="reap-after-death"> ++ <title> ++ Serialization of <constant>DEATH</constant> and <constant>REAP</constant> ++ </title> ++ <para> ++ The second guarantee is the serialization of ++ <constant>DEATH</constant> and <constant>REAP</constant> event ++ callbacks for a given thread. The actual reaping by the parent ++ (<function>release_task</function> call) can occur simultaneously ++ while the thread is still doing the final steps of dying, including ++ the <function>report_death</function> callback. If a tracing engine ++ has requested both <constant>DEATH</constant> and ++ <constant>REAP</constant> event reports, it's guaranteed that the ++ <function>report_reap</function> callback will not be made until ++ after the <function>report_death</function> callback has returned. ++ If the <function>report_death</function> callback itself detaches ++ from the thread, then the <function>report_reap</function> callback ++ will never be made. Thus it is safe for a ++ <function>report_death</function> callback to clean up data ++ structures and detach. ++ </para> ++ </sect2> ++ ++ <sect2 id="interlock"><title>Interlock with final callbacks</title> ++ <para> ++ The final sort of guarantee is that a tracing engine will know for sure ++ whether or not the <function>report_death</function> and/or ++ <function>report_reap</function> callbacks will be made for a certain ++ thread. These tear-down races are disambiguated by the error return ++ values of <function>utrace_set_events</function> and ++ <function>utrace_control</function>. Normally ++ <function>utrace_control</function> called with ++ <constant>UTRACE_DETACH</constant> returns zero, and this means that no ++ more callbacks will be made. If the thread is in the midst of dying, ++ it returns <constant>-EALREADY</constant> to indicate that the ++ <constant>report_death</constant> callback may already be in progress; ++ when you get this error, you know that any cleanup your ++ <function>report_death</function> callback does is about to happen or ++ has just happened--note that if the <function>report_death</function> ++ callback does not detach, the engine remains attached until the thread ++ gets reaped. If the thread is in the midst of being reaped, ++ <function>utrace_control</function> returns <constant>-ESRCH</constant> ++ to indicate that the <function>report_reap</function> callback may ++ already be in progress; this means the engine is implicitly detached ++ when the callback completes. This makes it possible for a tracing ++ engine that has decided asynchronously to detach from a thread to ++ safely clean up its data structures, knowing that no ++ <function>report_death</function> or <function>report_reap</function> ++ callback will try to do the same. <constant>utrace_detach</constant> ++ returns <constant>-ESRCH</constant> when the <structname>struct ++ utrace_engine</structname> has already been detached, but is ++ still a valid pointer because of its reference count. A tracing engine ++ can use this to safely synchronize its own independent multiple threads ++ of control with each other and with its event callbacks that detach. ++ </para> ++ ++ <para> ++ In the same vein, <function>utrace_set_events</function> normally ++ returns zero; if the target thread was stopped before the call, then ++ after a successful call, no event callbacks not requested in the new ++ flags will be made. It fails with <constant>-EALREADY</constant> if ++ you try to clear <constant>UTRACE_EVENT(DEATH)</constant> when the ++ <function>report_death</function> callback may already have begun, if ++ you try to clear <constant>UTRACE_EVENT(REAP)</constant> when the ++ <function>report_reap</function> callback may already have begun, or if ++ you try to newly set <constant>UTRACE_EVENT(DEATH)</constant> or ++ <constant>UTRACE_EVENT(QUIESCE)</constant> when the target is already ++ dead or dying. Like <function>utrace_control</function>, it returns ++ <constant>-ESRCH</constant> when the thread has already been detached ++ (including forcible detach on reaping). This lets the tracing engine ++ know for sure which event callbacks it will or won't see after ++ <function>utrace_set_events</function> has returned. By checking for ++ errors, it can know whether to clean up its data structures immediately ++ or to let its callbacks do the work. ++ </para> ++ </sect2> ++ ++ <sect2 id="barrier"><title>Using <function>utrace_barrier</function></title> ++ <para> ++ When a thread is safely stopped, calling ++ <function>utrace_control</function> with <constant>UTRACE_DETACH</constant> ++ or calling <function>utrace_set_events</function> to disable some events ++ ensures synchronously that your engine won't get any more of the callbacks ++ that have been disabled (none at all when detaching). But these can also ++ be used while the thread is not stopped, when it might be simultaneously ++ making a callback to your engine. For this situation, these calls return ++ <constant>-EINPROGRESS</constant> when it's possible a callback is in ++ progress. If you are not prepared to have your old callbacks still run, ++ then you can synchronize to be sure all the old callbacks are finished, ++ using <function>utrace_barrier</function>.

All callbacks take an @engine ++ * argument. The @report_reap callback takes a @task argument that ++ * might or might not be @current. All other @report_* callbacks ++ * report an event in the @current task. ++ * ++ * For some calls, @action also includes bits specific to that event ++ * and utrace_resume_action() is used to extract the resume action. ++ * This shows what would happen if @engine wasn't there, or will if ++ * the callback's return value uses %UTRACE_RESUME. This always ++ * starts as %UTRACE_RESUME when no other tracing is being done on ++ * this task. ++ * ++ * All return values contain &enum utrace_resume_action bits. For ++ * some calls, other bits specific to that kind of event are added to ++ * the resume action bits with OR. These are the same bits used in ++ * the @action argument. The resume action returned by a callback ++ * does not override previous engines' choices, it only says what ++ * @engine wants done. What @current actually does is the action that's ++ * most constrained among the choices made by all attached engines. ++ * See utrace_control() for more information on the actions. ++ * ++ * When %UTRACE_STOP is used in @report_syscall_entry, then @current ++ * stops before attempting the system call. In this case, another ++ * @report_syscall_entry callback will follow after @current resumes if ++ * %UTRACE_REPORT or %UTRACE_INTERRUPT was returned by some callback ++ * or passed to utrace_control(). In a second or later callback, ++ * %UTRACE_SYSCALL_RESUMED is set in the @action argument to indicate ++ * a repeat callback still waiting to attempt the same system call ++ * invocation. This repeat callback gives each engine an opportunity ++ * to reexamine registers another engine might have changed while ++ * @current was held in %UTRACE_STOP. ++ * ++ * In other cases, the resume action does not take effect until @current ++ * is ready to check for signals and return to user mode. If there ++ * are more callbacks to be made, the last round of calls determines ++ * the final action. A @report_quiesce callback with @event zero, or ++ * a @report_signal callback, will always be the last one made before ++ * @current resumes. Only %UTRACE_STOP is "sticky"--if @engine returned ++ * %UTRACE_STOP then @current stays stopped unless @engine returns ++ * different from a following callback. ++ * ++ * The report_death() and report_reap() callbacks do not take @action ++ * arguments, and only %UTRACE_DETACH is meaningful in the return value ++ * from a report_death() callback. None of the resume actions applies ++ * to a dead thread. ++ * ++ * All @report_*() hooks are called with no locks held, in a generally ++ * safe environment when we will be returning to user mode soon (or just ++ * entered the kernel). It is fine to block for memory allocation and ++ * the like, but all hooks are asynchronous and must not block on ++ * external events! If you want the thread to block, use %UTRACE_STOP ++ * in your hook's return value; then later wake it up with utrace_control(). ++ * ++ * @report_quiesce: ++ * Requested by %UTRACE_EVENT(%QUIESCE). ++ * This does not indicate any event, but just that @current is in a ++ * safe place for examination. This call is made before each specific ++ * event callback, except for @report_reap. The @event argument gives ++ * the %UTRACE_EVENT(@which) value for the event occurring. This ++ * callback might be made for events @engine has not requested, if ++ * some other engine is tracing the event; calling utrace_set_events() ++ * call here can request the immediate callback for this occurrence of ++ * @event. @event is zero when there is no other event, @current is ++ * now ready to check for signals and return to user mode, and some ++ * engine has used %UTRACE_REPORT or %UTRACE_INTERRUPT to request this ++ * callback. For this case, if @report_signal is not %NULL, the ++ * @report_quiesce callback may be replaced with a @report_signal ++ * callback passing %UTRACE_SIGNAL_REPORT in its @action argument, ++ * whenever @current is entering the signal-check path anyway. ++ * ++ * @report_signal: ++ * Requested by %UTRACE_EVENT(%SIGNAL_*) or %UTRACE_EVENT(%QUIESCE). ++ * Use utrace_signal_action() and utrace_resume_action() on @action. ++ * The signal action is %UTRACE_SIGNAL_REPORT when some engine has ++ * used %UTRACE_REPORT or %UTRACE_INTERRUPT; the callback can choose ++ * to stop or to deliver an artificial signal, before pending signals. ++ * It's %UTRACE_SIGNAL_HANDLER instead when signal handler setup just ++ * finished (after a previous %UTRACE_SIGNAL_DELIVER return); this ++ * serves in lieu of any %UTRACE_SIGNAL_REPORT callback requested by ++ * %UTRACE_REPORT or %UTRACE_INTERRUPT, and is also implicitly ++ * requested by %UTRACE_SINGLESTEP or %UTRACE_BLOCKSTEP into the ++ * signal delivery. The other signal actions indicate a signal about ++ * to be delivered; the previous engine's return value sets the signal ++ * action seen by the the following engine's callback. The @info data ++ * can be changed at will, including @info->si_signo. The settings in ++ * @return_ka determines what %UTRACE_SIGNAL_DELIVER does. @orig_ka ++ * is what was in force before other tracing engines intervened, and ++ * it's %NULL when this report began as %UTRACE_SIGNAL_REPORT or ++ * %UTRACE_SIGNAL_HANDLER. For a report without a new signal, @info ++ * is left uninitialized and must be set completely by an engine that ++ * chooses to deliver a signal; if there was a previous @report_signal ++ * callback ending in %UTRACE_STOP and it was just resumed using ++ * %UTRACE_REPORT or %UTRACE_INTERRUPT, then @info is left unchanged ++ * from the previous callback. In this way, the original signal can ++ * be left in @info while returning %UTRACE_STOP|%UTRACE_SIGNAL_IGN ++ * and then found again when resuming with %UTRACE_INTERRUPT. ++ * The %UTRACE_SIGNAL_HOLD flag bit can be OR'd into the return value, ++ * and might be in @action if the previous engine returned it. This ++ * flag asks that the signal in @info be pushed back on @current's queue ++ * so that it will be seen again after whatever action is taken now. ++ * ++ * @report_clone: ++ * Requested by %UTRACE_EVENT(%CLONE). ++ * Event reported for parent, before the new task @child might run. ++ * @clone_flags gives the flags used in the clone system call, or ++ * equivalent flags for a fork() or vfork() system call. This ++ * function can use utrace_attach_task() on @child. Then passing ++ * %UTRACE_STOP to utrace_control() on @child here keeps the child ++ * stopped before it ever runs in user mode, %UTRACE_REPORT or ++ * %UTRACE_INTERRUPT ensures a callback from @child before it ++ * starts in user mode. ++ * ++ * @report_jctl: ++ * Requested by %UTRACE_EVENT(%JCTL). ++ * Job control event; @type is %CLD_STOPPED or %CLD_CONTINUED, ++ * indicating whether we are stopping or resuming now. If @notify ++ * is nonzero, @current is the last thread to stop and so will send ++ * %SIGCHLD to its parent after this callback; @notify reflects ++ * what the parent's %SIGCHLD has in @si_code, which can sometimes ++ * be %CLD_STOPPED even when @type is %CLD_CONTINUED. ++ * ++ * @report_exec: ++ * Requested by %UTRACE_EVENT(%EXEC). ++ * An execve system call has succeeded and the new program is about to ++ * start running. The initial user register state is handy to be tweaked ++ * directly in @regs. @fmt and @bprm gives the details of this exec. ++ * ++ * @report_syscall_entry: ++ * Requested by %UTRACE_EVENT(%SYSCALL_ENTRY). ++ * Thread has entered the kernel to request a system call. ++ * The user register state is handy to be tweaked directly in @regs. ++ * The @action argument contains an &enum utrace_syscall_action, ++ * use utrace_syscall_action() to extract it. The return value ++ * overrides the last engine's action for the system call. ++ * If the final action is %UTRACE_SYSCALL_ABORT, no system call ++ * is made. The details of the system call being attempted can ++ * be fetched here with syscall_get_nr() and syscall_get_arguments(). ++ * The parameter registers can be changed with syscall_set_arguments(). ++ * See above about the %UTRACE_SYSCALL_RESUMED flag in @action. ++ * Use %UTRACE_REPORT in the return value to guarantee you get ++ * another callback (with %UTRACE_SYSCALL_RESUMED flag) in case ++ * @current stops with %UTRACE_STOP before attempting the system call. ++ * ++ * @report_syscall_exit: ++ * Requested by %UTRACE_EVENT(%SYSCALL_EXIT). ++ * Thread is about to leave the kernel after a system call request. ++ * The user register state is handy to be tweaked directly in @regs. ++ * The results of the system call attempt can be examined here using ++ * syscall_get_error() and syscall_get_return_value(). It is safe ++ * here to call syscall_set_return_value() or syscall_rollback(). ++ * ++ * @report_exit: ++ * Requested by %UTRACE_EVENT(%EXIT). ++ * Thread is exiting and cannot be prevented from doing so, ++ * but all its state is still live. The @code value will be ++ * the wait result seen by the parent, and can be changed by ++ * this engine or others. The @orig_code value is the real ++ * status, not changed by any tracing engine. Returning %UTRACE_STOP ++ * here keeps @current stopped before it cleans up its state and dies, ++ * so it can be examined by other processes. When @current is allowed ++ * to run, it will die and get to the @report_death callback. ++ * ++ * @report_death: ++ * Requested by %UTRACE_EVENT(%DEATH). ++ * Thread is really dead now. It might be reaped by its parent at ++ * any time, or self-reap immediately. Though the actual reaping ++ * may happen in parallel, a report_reap() callback will always be ++ * ordered after a report_death() callback. ++ * ++ * @report_reap: ++ * Requested by %UTRACE_EVENT(%REAP). ++ * Called when someone reaps the dead task (parent, init, or self). ++ * This means the parent called wait, or else this was a detached ++ * thread or a process whose parent ignores SIGCHLD. ++ * No more callbacks are made after this one. ++ * The engine is always detached. ++ * There is nothing more a tracing engine can do about this thread. ++ * After this callback, the @engine pointer will become invalid. ++ * The @task pointer may become invalid if get_task_struct() hasn't ++ * been used to keep it alive. ++ * An engine should always request this callback if it stores the ++ * @engine pointer or stores any pointer in @engine->data, so it ++ * can clean up its data structures. ++ * Unlike other callbacks, this can be called from the parent's context ++ * rather than from the traced thread itself--it must not delay the ++ * parent by blocking. ++ * ++ * @release: ++ * If not %NULL, this is called after the last utrace_engine_put() ++ * call for a &struct utrace_engine, which could be implicit after ++ * a %UTRACE_DETACH return from another callback.

The thread will start running ++ * again if it was stopped and no longer has any attached engines ++ * that want it stopped. ++ * ++ * If the @report_reap callback may already have begun, this fails ++ * with -%ESRCH. If the @report_death callback may already have ++ * begun, this fails with -%EALREADY. ++ * ++ * If @target is not already stopped, then a callback to this engine ++ * might be in progress or about to start on another CPU. If so, ++ * then this returns -%EINPROGRESS; the detach happens as soon as ++ * the pending callback is finished. To synchronize after an ++ * -%EINPROGRESS return, see utrace_barrier(). ++ * ++ * If @target is properly stopped before utrace_control() is called, ++ * then after successful return it's guaranteed that no more callbacks ++ * to the @engine->ops vector will be made. ++ * ++ * The only exception is %SIGKILL (and exec or group-exit by another ++ * thread in the group), which can cause asynchronous @report_death ++ * and/or @report_reap callbacks even when %UTRACE_STOP was used. ++ * (In that event, this fails with -%ESRCH or -%EALREADY, see above.) ++ * ++ * UTRACE_STOP: ++ * ++ * This asks that @target stop running. This returns 0 only if ++ * @target is already stopped, either for tracing or for job ++ * control. Then @target will remain stopped until another ++ * utrace_control() call is made on @engine; @target can be woken ++ * only by %SIGKILL (or equivalent, such as exec or termination by ++ * another thread in the same thread group). ++ * ++ * This returns -%EINPROGRESS if @target is not already stopped. ++ * Then the effect is like %UTRACE_REPORT.

For that, use %UTRACE_INTERRUPT. ++ * To interrupt system calls and then keep @target stopped, your ++ * @report_signal callback can return %UTRACE_STOP. ++ * ++ * UTRACE_RESUME: ++ * ++ * Just let @target continue running normally, reversing the effect ++ * of a previous %UTRACE_STOP. If another engine is keeping @target ++ * stopped, then it remains stopped until all engines let it resume. ++ * If @target was not stopped, this has no effect. ++ * ++ * UTRACE_REPORT: ++ * ++ * This is like %UTRACE_RESUME, but also ensures that there will be ++ * a @report_quiesce or @report_signal callback made soon. If ++ * @target had been stopped, then there will be a callback before it ++ * resumes running normally. If another engine is keeping @target ++ * stopped, then there might be no callbacks until all engines let ++ * it resume. ++ * ++ * Since this is meaningless unless @report_quiesce callbacks will ++ * be made, it returns -%EINVAL if @engine lacks %UTRACE_EVENT(%QUIESCE). ++ * ++ * UTRACE_INTERRUPT: ++ * ++ * This is like %UTRACE_REPORT, but ensures that @target will make a ++ * @report_signal callback before it resumes or delivers signals. ++ * If @target was in a system call or about to enter one, work in ++ * progress will be interrupted as if by %SIGSTOP. If another ++ * engine is keeping @target stopped, then there might be no ++ * callbacks until all engines let it resume. ++ * ++ * This gives @engine an opportunity to introduce a forced signal ++ * disposition via its @report_signal callback. ++ * ++ * UTRACE_SINGLESTEP: ++ * ++ * It's invalid to use this unless arch_has_single_step() returned true. ++ * This is like %UTRACE_RESUME, but resumes for one user instruction only. ++ * ++ * Note that passing %UTRACE_SINGLESTEP or %UTRACE_BLOCKSTEP to ++ * utrace_control() or returning it from an event callback alone does ++ * not necessarily ensure that stepping will be enabled.

The 3304 is unsurprisingly quite +similar to the 3305, and empirical testing yeilds far better results +and more complete functionality by merging 3304 support into the 3305 +driver. (For example, the current lgdt3304 driver lacks support for +signal strength, snr, ucblocks, etc., which we get w/the lgdt3305). + +For the moment, not dropping the lgdt3304 driver, and its still up to +a given device's config setup to choose which demod driver to use, but +I'd suggest dropping the 3304 driver entirely. + +As a follow-up to this patch, I've got another patch that adds support +for the KWorld PlusTV 340U (ATSC) em2870-based tuner stick, driving +its lgdt3304 demod via this lgdt3305 driver, which is what I used to +successfully test this patch with both VSB_8 and QAM_256 signals. + +A few pieces are still a touch crude, but I think its a solid start, +as well as much cleaner and more feature-complete than the existing +lgdt3304 driver. + +Signed-off-by: Jarod Wilson <jarod@redhat.com> +--- + drivers/media/dvb/frontends/lgdt3305.c | 206 ++++++++++++++++++++++++++++++-- + drivers/media/dvb/frontends/lgdt3305.h | 6 + + 2 files changed, 203 insertions(+), 9 deletions(-) + +diff --git a/drivers/media/dvb/frontends/lgdt3305.c b/drivers/media/dvb/frontends/lgdt3305.c +index fde8c59..40695e6 100644 +--- a/drivers/media/dvb/frontends/lgdt3305.c ++++ b/drivers/media/dvb/frontends/lgdt3305.c +@@ -1,5 +1,5 @@ + /* +- * Support for LGDT3305 - VSB/QAM ++ * Support for LG Electronics LGDT3304 and LGDT3305 - VSB/QAM + * + * Copyright (C) 2008, 2009 Michael Krufky <mkrufky@linuxtv.org> + * +@@ -357,7 +357,10 @@ static int lgdt3305_rfagc_loop(struct lgdt3305_state *state, + case QAM_256: + agcdelay = 0x046b; + rfbw = 0x8889; +- ifbw = 0x8888; ++ if (state->cfg->demod_chip == LGDT3305) ++ ifbw = 0x8888; ++ else ++ ifbw = 0x6666; + break; + default: + return -EINVAL; +@@ -409,8 +412,18 @@ static int lgdt3305_agc_setup(struct lgdt3305_state *state, + lg_dbg("lockdten = %d, acqen = %d\n", lockdten, acqen); + + /* control agc function */ +- lgdt3305_write_reg(state, LGDT3305_AGC_CTRL_4, 0xe1 | lockdten << 1); +- lgdt3305_set_reg_bit(state, LGDT3305_AGC_CTRL_1, 2, acqen); ++ switch (state->cfg->demod_chip) { ++ case LGDT3304: ++ lgdt3305_write_reg(state, 0x0314, 0xe1 | lockdten << 1); ++ lgdt3305_set_reg_bit(state, 0x030e, 2, acqen); ++ break; ++ case LGDT3305: ++ lgdt3305_write_reg(state, LGDT3305_AGC_CTRL_4, 0xe1 | lockdten << 1); ++ lgdt3305_set_reg_bit(state, LGDT3305_AGC_CTRL_1, 2, acqen); ++ break; ++ default: ++ return -EINVAL; ++ } + + return lgdt3305_rfagc_loop(state, param); + } +@@ -543,6 +556,11 @@ static int lgdt3305_i2c_gate_ctrl(struct dvb_frontend *fe, int enable) + enable ?

This avoids those hard hangs +on those devices with no SPROM attached to their SSB bus.
