* MFC r271394, r271398:ian2015-02-121-1/+1
| | | | | | | Add more register values to armreg.h and remove CPU_CONTROL_32BP_ENABLE from asm.h as they were already defined in armreg.h. Unify interrupts bit definition and usage. While here remove PSR_C_bit.

| | | | | | | | | | | | | | | | | | | | | | exhausted. - Add a new protect(1) command that can be used to set or revoke protection from arbitrary processes. Similar to ktrace it can apply a change to all existing descendants of a process as well as future descendants. - Add a new procctl(2) system call that provides a generic interface for control operations on processes (as opposed to the debugger-specific operations provided by ptrace(2)). procctl(2) uses a combination of idtype_t and an id to identify the set of processes on which to operate similar to wait6(). - Add a PROC_SPROTECT control operation to manage the protection status of a set of processes. MADV_PROTECT still works for backwards compatability. - Add a p_flag2 to struct proc (and a corresponding ki_flag2 to kinfo_proc) the first bit of which is used to track if P_PROTECT should be inherited by new child processes.

To facilitate this, add a new parameter to vm_map_find() that specifies an optional maximum virtual address. While here, fix several callers of vm_map_find() to use a VMFS_* constant for the findspace argument instead of TRUE and FALSE. Reviewed by: alc Approved by: re (kib)

| | | | | | | | | | | | | | | | | | | | | | | | | address alignment of mappings. - MAP_ALIGNED(n) requests a mapping aligned on a boundary of (1 << n). Requests for n >= number of bits in a pointer or less than the size of a page fail with EINVAL. This matches the API provided by NetBSD. - MAP_ALIGNED_SUPER is a special case of MAP_ALIGNED. It can be used to optimize the chances of using large pages. By default it will align the mapping on a large page boundary (the system is free to choose any large page size to align to that seems best for the mapping request). However, if the object being mapped is already using large pages, then it will align the virtual mapping to match the existing large pages in the object instead. - Internally, VMFS_ALIGNED_SPACE is now renamed to VMFS_SUPER_SPACE, and VMFS_ALIGNED_SPACE(n) is repurposed for specifying a specific alignment. MAP_ALIGNED(n) maps to using VMFS_ALIGNED_SPACE(n), while MAP_ALIGNED_SUPER maps to VMFS_SUPER_SPACE. - mmap() of a device object now uses VMFS_OPTIMAL_SPACE rather than explicitly using VMFS_SUPER_SPACE. All device objects are forced to use a specific color on creation, so VMFS_OPTIMAL_SPACE is effectively equivalent. Reviewed by: alc MFC after: 1 month

* - Fix detaching under some circumstances.zont2012-09-123-14/+37
| | | | | | | | | | | | | | | | | | | | | When truss is detaching from very active process it is possible to hang on waitpid(2) in restore_proc() forever, because ptrace(PT_SYSCALL) must be called before detaching, to allow the debugging process to continue execution. Also when truss called with '-c' argument, it does not print anything after detach, because it immediately exits from restore_proc(). To fix these two problems make detaching deferred, but then it is impossible to detach from a process which does not do any system call. To fix this issue use sigaction(2) instead of signal(3) to disable SA_RESTART flag for waitpid(2) that makes it non-restartable. Remove global variable child_pid, because now detaching is handled in context where child's pid is known. Reported by: mjg Tested by: mjg, swills Approved by: kib (mentor) MFC after: 2 weeks

| | | | | | | | | | | | This matches the constants from <signal.h> with 'SIG' removed, which POSIX requires kill and trap to accept and 'kill -l' to write. 'kill -l', 'trap', 'trap -l' output is now upper case. In Turkish locales, signal names with an upper case 'I' are now accepted, while signal names with a lower case 'i' are no longer accepted, and the output of 'killall -l' now contains proper capital 'I' without dot instead of a dotted capital 'I'.
