b2f8a79c3b sched/signal: Add support for SIGPIPE. SIGPIPE uses SIG_SIGPIPE_ACTION which terminates process by default. It also could be ignored. 2019-10-17 11:29:39 -06:00

a7265d71c6 This commit adds support for default signal actions for SIGSTOP, SIGSTP, and SIGCONT.
Squashed commit of the following:

    Add procfs support to show stopped tasks.  Add nxsig_action() to solve a chicken and egg problem:  We needed to use sigaction to set default actions, but sigaction() would refuse to set actions if the default actions could not be caught or ignored.

    sched/signal:  Add configuration option to selectively enabled/disable default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT.  Fix some compilation issues.

    sched/sched:  Okay.. I figured out a way to handle state changes that may occur while they were stopped. If a task/thread was already blocked when SIGSTOP/SIGSTP was received, it will restart in the running state.  I will appear that to the task/thread that the blocked condition was interrupt by a signal and returns the EINTR error.

    sched/group and sched/sched:  Finish framework for continue/resume logic.

0756cf66ed sched/signal: Add support for SIGINT in addition to SIGKILL. drivers/serial: Use SIGINT instead of SIGKILL when control-C is pressed. 2018-08-28 12:15:31 -06:00

499b89feed sched/signal: Default Signal Actions. Change some types to superficially simplify. Add configuration options to enabled default signal behaviors on a per-signal basis. I don't think users are prepared for SIGALRM to terminate the task (which is the correct default behavior if you don't change it). Extend the implementation of default signals so that it is totally table driven and extensible by simply mondifying the content of const tables. 2018-08-27 15:37:43 -06:00

6d094e4b33 sched/signals: Update the signal default action logic to support sigaction(). signaction() must be able to handle and input action of SIG_DFL to setup the default signal action; it mast also return SIG_DFL it is replacing the default action. 2018-08-27 13:13:23 -06:00

c0d234a474 Squashed commit of the following:
drivers/serial/Kconfig:  It is no longer necessary to restrict Ctrl-C handling to the FLAT build

    sched/signal:  Add a new configuration option to select signal default actions, separate handling of signal default actions from both task startup logic and from the serial TTY Ctrl-C logic.  Add a signal set in the group structure to keep track of what signals have been set to the default action.  In dispatching signals in PROTECTED or KERNEL mode, use this signal set to determine if the default signal handler is attached and dispatch the signal in kernel mode for the default actions.

11f8dc735c Squashed commit of the following:
drivers/serial:  Add Ctrl-C/Ctrl-X support.  This is an initial working implementation that still requires that several details be resolved.

    sched/task/task_start.c: Add default signal action to SIGKILL.

28a4ca6713 libc/signal and include/signal.h: Rename sigset() to signal(). sigset() is the System V function; signal() is the obsoleted POSIX name. These seem to be equivalent. Neither are relevant in modern POSIX programming but the name signal() probably has better credentials. sigset() is now relegated to a #define in signal.h that makes it equivalent to signal(). 2016-04-10 14:35:45 -06:00
