20. Kernel Data Structures for Managing Signals

Describe the key signal-related fields within the task_struct in Linux. How does the kernel use these fields to manage pending signals?

Here are the key data structures for managing signals:

struct signal_struct *signal: Points to a structure containing signal-related information shared among threads in a thread group.

struct signal_struct *sighand: Points to the signal handlers of the process.

sigset_t blocked: The signal mask indicating which signals are currently blocked.

struct sigpending pending: The pending signals for the specific task.
