* As new objects begin to support new labels, start to generalizeRobert Watson2003-08-221-86/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the default label support in /etc/mac.conf. Rather than maintain each default label type in an explicit global variable in mac.c, keep a list of defaults loaded from the configuration file. Generalize the parsing so that we support both the older: default_file_labels foo default_ifnet_labels foo default_process_labels foo And also a new: default_labels file foo default_labels ifnet foo default_labels process foo We now accept arbitrary object classes in the first argument. If the same object is specified more than once, we discard the earlier definition in favor of the later one. Add a new API, mac_prepare_type(), which accepts a mac_t to prepare, as well as an object name in the second argument, which will pull a default label set for the object out of the configuration loaded by mac_init_internal(). This permits the libc to adapt to new objects known about by applications but not by libc at compile-time. Also liberalize the error handling a bit: if we're using implicit initialization (i.e., the application didn't explicitly initialize the MAC code), ignore syntax errors and only use valid lines. In the future, we may want to add explicit warnings and do this a bit more consistently. While here, add support for a MAC_CONFFILE environmental variable, which may be used to specify an alternative mac.conf configuration file if the application isn't running with modified privilege (issetugid()).

* Add a kluge suggested by Marcel to paper over the difference betweenGarrett Wollman2003-08-192-0/+4
| | | | | | | | | | | | | | | gethostname()'s old and new signatures without requiring a library bump. Note that programs which called gethostname() with a negative argument were already broken, since the same type conversion was done by the old implementation. Add a note in the Makefile so that whoever next bumps the libc revision will delete the kluge at the same time (as it will no longer be necessary). This is only operative on 64-bit platforms.

* Change gethostname() to set errno to ENAMETOOLONG instead of ENOMEMGarrett Wollman2003-08-192-18/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | when the buffer is not long enough to hold the current host name. POSIX does not standardize error returns for gethostname(), so it doesn't matter which one we use, but ENAMETOOLONG is at least a little more intuitive, and mi suggests the existence of prior art. I've been running with this change for a while on my home machine with no effect. At the same time, I've updated the prototype for gethostname() to use the correct standard type (size_t) for the namelen argument. All of the in-tree callers fall into one of the following categories: 1) Call perror() or equivalent when gethostname() fails. 2) Ignore gethostname()'s return value entirely, potentially resulting in data corruption if the buffer is too small. 3) Fall back to a (possibly sensible) default value if gethostname() fails. Many of the callers I examined shows signs of confusion about the correct sizing of the host name buffer. gethostname(3) now has more information about this, as well as updated standards information.

| | | | | | | | | | | | | | | | | | | | | | | | | | - 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).

This avoids having dirty registers and saves us from having to manually write them to the backing store from within the kernel. In that respect, flushing the RSE is both functionally required as well as performance optimal. On average we had 18 dirty registers when getcontext(2) was called from libthr. Since libthr does not switch back to a context created by getcontext(2), not having dealt with the dirty registers was harmless. Notes: svn path=/head/; revision=118332
