* Clarify the behavior of ptrace(2) a little bit: the tracing processrwatson2004-01-101-0/+24
| | | | | | | | | | | | | | | must first attach to the traced process. If the tracing process exits without detaching, the traced process will be killed rather than continued. For the duration of the tracing session, the traced process is reparented to the tracing process (with resulting expected behaviors). It is permissible to trace more than one other process at a time. When using waitpid() to monitor the behavior of the traced process, signals are intercepted: they may optionally then be forwarded using ptrace(). Signals are generated normally by and for the process, but also by the tracing facility (SIGTRAP). Product of: Suffering Sponsored by: DARPA, AFRL

Before the MNT_BYFSID changes, unmount(2) used to return ENOENT for a nonexistent path and EINVAL for a non-mountpoint, but we can no longer distinguish between these cases. Of the two error codes, EINVAL was more likely to occur in practice, and it was the only one of the two that was documented. Update the manual page to match the current behaviour.

* Add the mlockall() and munlockall() system calls.bms2003-08-111-2/+3
| | | | | | | | | | | | | | | | | | | | | | | - All those diffs to syscalls.master for each architecture *are* necessary. This needed clarification; the stub code generation for mlockall() was disabled, which would prevent applications from linking to this API (suggested by mux) - Giant has been quoshed. It is no longer held by the code, as the required locking has been pushed down within vm_map.c. - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES to express their intention explicitly. - Inspected at the vmstat, top and vm pager sysctl stats level. Paging-in activity is occurring correctly, using a test harness. - The RES size for a process may appear to be greater than its SIZE. This is believed to be due to mappings of the same shared library page being wired twice. Further exploration is needed. - Believed to back out of allocations and locks correctly (tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).

| | | | | | | | | | | | | | | | | | system by specifying the file system ID instead of a path. Use this by default in umount(8). This avoids the need to perform any vnode operations to look up the mount point, so it makes it possible to unmount a file system whose root vnode cannot be looked up (e.g. due to a dead NFS server, or a file system that has become detached from the hierarchy because an underlying file system was unmounted). It also provides an unambiguous way to specify which file system is to be unmunted. Since the ability to unmount using a path name is retained only for compatibility, that case now just uses a simple string comparison of the supplied path against f_mntonname of each mounted file system.
