header.
* Added fields necessary to make it possible to retrieve more than one
dirent from the underlying file system.
* Unless some app creates a DIR on its own to it to feed readdir(), this
change should be binary compatible. If we find an application misbehaving,
we can still make it a GCC4 only thing.
* fs_attr/fs_index/fs_query now all use readdir() directly (as that one
contains the logic to iterate through a number of dirents in userspace).

* It was not self containing, as it used size_t without defining it.
* It was not C++ safe.
* It used the restrict keyword that is not recognized in GCC2. This fixes bug
#2262.
* It did not contain parameter names as demanded by our coding style.

I added an #error directive, so configure scripts shouldn't be fooled.

PTHREAD_SCOPE_SYSTEM which makes the implementation rather simple.

- *pathconf() now uses statvfs and fs_info data when appropriate. It should also check for file type though, some only apply to directory or others.
- added confstr(_CS_PATH) with a sensible default.

vm_page_write_modified_pages(), save that it only writes pages in the
given range.
* Added vm_page_schedule_write_page_range() which schedules all modified
pages in the given cache's range for writing by the page writer.
* Added _kern_sync_memory() syscall and the msync() POSIX function.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25620 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the pthread_cond_t internals public. This is necessary to support
process shared condition variables. Fixed initializer macro.
* Made the pthread_rwlockattr_t structure opaque.
* pthread_t is no longer typedef'ed to int. It's the pointer to the
internal _pthread_thread structure.
* Removed __get_pthread(). pthread_self() can be used instead.
* No longer tunnel the pthread exit value through Haiku's thread exit
value. We do have a separate field in the _pthread_thread structure
for it, now.
* Handle detaching of threads correctly.
* pthread_rwlockattr_{g,s}etpshared() use the
PTHREAD_PROCESS_{SHARED,PRIVATE} constants, now.
* Commented out yet unsupported structures (barriers, spinlocks).
* Rebuilt APR optional package. The pthread changes weren't binary
compatible.

particularly efficient.
* pthread_mutex implementation:
- Removed the pthread_mutex_t indirection (the type was a pointer to
the actual structure which was allocated on the heap), as it made
sharing the mutex between processes impossible.
- Removed the distinction between process shared and non-shared
mutexes. Benaphores work just as well in shared memory, so we always
use them.
* Fixed some static initializer macros. PTHREAD_COND_INITIALIZER is
still broken, since it doesn't work in C code.

* Changed the semantics of unnamed semaphores. Before parent and child
of a fork() would always share an earlier created semaphore. Now we do
that only, if the "shared" parameter of sem_init() was true. That's
still not quite the behavior Linux and Solaris have, but should be
perfectly fine with how reasonable code would use the API.
* There's a global table for shared unnamed semaphores now. ATM a
semaphore is leaked when no one explicitly destroys it (just as with
named sems).
* Enforce per-team and global semaphore number limits.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25362 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added POSIX semaphore related macros.

registrar provides access to the DBs via a port message based
protocol. The functions in libroot just ask the registrar now.
* Added Linuxish shadow passwd support. No putspent() though -- we'll
provide private functions.

and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
path to an FD parameter. Changed vm_map_file() accordingly and
adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
and map_backing_store(). If true and the address specification is
B_EXACT_ADDRESS, all areas in the specified address range will be
deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
fork()ing those areas won't be copied CoW, but rather be cloned. This
is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
that we can't partially unmap areas. Otherwise the functions should be
rather compliant. We also support the non-POSIX extension
MAP_ANONYMOUS.

* Since we use a 1:1 mapping, they don't do anything besides remembering the
level set, though.

functions by ones reading /etc/{group,passwd}.
* Added quasi-standard getpwent_r() and getgrent_r().
* Added _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX sysconf()
constants.
* Moved initgroups() and getgrouplist() definition to grp.cpp. They use
the same backend as the <grp.h> functions.
* Set the permissions of files created by the build system to what they
should be on the image (executables: 755, others: 644). Otherwise only
root could do anything under Haiku.
* Added build system variables HAIKU_ROOT_USER_NAME and
HAIKU_ROOT_USER_REAL_NAME to customize name and real name of Haiku's
root user.
* Added build system rules AddUserToHaikuImage and AddGroupToHaikuImage
for adding additional users and groups (by default only root user and
group and a "users" group are created).
* Adjusted BIND port and coreutils config.h files according to what
features have become available.
* Fixed HAIKU_DOCUMENTATION_OBJECT_DIR definition. Untested, but it used
a wrong variable name before.

* Implemented pthread_setcanceltype(), pthread_setcancelstate(), and
pthread_testcancel().
* In the previous commit, I also made pthread_private.h self-contained.

structure that is attached (via TLS) to each pthread.
* Implemented support for pthread_cleanup_{push|pop}().
* I haven't really been able to test these changes, yet, though.

- Added a "root" vnode to the io_context. It is used for resolving
paths and converting nodes to paths instead of sRoot. Some more
passing around of io_context structures was necessary.
- Introduced a new lock sIOContextRootLock to protect
io_context::root. The current uses of io_context::io_mutex
(put_vnode(), remove_vnode() while holding it) looked too suspicious
to use that mutex in vnode_path_to_vnode().
- Added _kern_change_root() syscall and chroot() libroot function.
- Added chroot coreutils program to the image. Funnily it seems to be
much easier to set up a little jail than under Linux (just copy
bash and libroot.so into respective subdirs; mount another pipefs
if you want pipe support).
With Haiku allowing direct access to directories via inode IDs
jailing is obviously not very secure at the moment.
- Added /var/empty to the image. It will be the chroot target for ssh.
* Changed vfs.cpp:get_cwd() so that the io_context::io_mutex is no
longer held when calling dir_vnode_to_path().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24673 a95241bf-73f2-0310-859d-f6bbb57e9c96
- The kernel stores the group IDs in the team structure. They are
correctly inherited on fork() and load_image_etc().
- Implemented getgroups() for real, i.e. it retrieves the groups
associated with the process.
- Implemented setgroups(), initgroups() and (the BSDish)
getgrouplist(). The latter two read the group information from the
"group database" /etc/group (if existing).
- Change the BIND port config, since we do have getgrouplist() now.
* The set-uid feature was broken when the path to the executable was
relative, since we used stat(), which, in the kernel, uses the kernel
IO context.
