Add a mask of optional ptrace() events. 302900: Add a test for user signal delivery. This test verifies we get the correct ptrace event details when a signal is posted to a traced process from userland. 302902: Add a mask of optional ptrace() events. ptrace() now stores a mask of optional events in p_ptevents. Currently this mask is a single integer, but it can be expanded into an array of integers in the future. Two new ptrace requests can be used to manipulate the event mask: PT_GET_EVENT_MASK fetches the current event mask and PT_SET_EVENT_MASK sets the current event mask. The current set of events include: - PTRACE_EXEC: trace calls to execve(). - PTRACE_SCE: trace system call entries. - PTRACE_SCX: trace syscam call exits. - PTRACE_FORK: trace forks and auto-attach to new child processes. - PTRACE_LWP: trace LWP events. The S_PT_SCX and S_PT_SCE events in the procfs p_stops flags have been replaced by PTRACE_SCE and PTRACE_SCX. PTRACE_FORK replaces P_FOLLOW_FORK and PTRACE_LWP replaces P2_LWP_EVENTS. The PT_FOLLOW_FORK and PT_LWP_EVENTS ptrace requests remain for compatibility but now simply toggle corresponding flags in the event mask. While here, document that PT_SYSCALL, PT_TO_SCE, and PT_TO_SCX both modify the event mask and continue the traced process. 302921: Rename PTRACE_SYSCALL to LINUX_PTRACE_SYSCALL. 303461: Note that not all optional ptrace events use SIGTRAP. New child processes attached due to PTRACE_FORK use SIGSTOP instead of SIGTRAP. All other ptrace events use SIGTRAP. 304009: Remove description of P_FOLLOWFORK as this flag was removed.
