POSIX: ioctl(fd, op, arg) equals ioctl(fd, op, arg, 0)

The ioctl call cannot know the expected number of arguments
because it depends on the specific ioctl being used, and the
same value could be used to do different things by different
devices. Without knowing that, it is not safe to use va_arg
(at best a random value will be read from the stack, at worst,
it will just crash).

This changes the implementation of ioctl in two ways:
- For C++ code: a 4 argument function with default values
for arguments 3 and 4.
- For C code: wrap arguments 3 and 4 in a struct with the
help of a macro, providing something that behaves like the
C++ version.

So, with this new code:
- Calling ioctl with only 3 arguments sets the 4th one to 0
- Calling ioctl with only 2 arguments sets the 3rd and 4th to 0
- Calling with 1 or 5+ arguments is a compile time error

The existing ioctl symbol is preserved for ABI compatibility.

POSIX: lseek: support SEEK_DATA and SEEK_HOLE constants

this implementation calls the ioctl hook of the filesystem with BSD-like constants
FIOSEEKDATA and FIOSEEKHOLE. if the hook doesn't know the constants, we use the stat size
to return the last hole (as proposed in the draft spec).

Revert "libroot: Undefine constants for unsupported POSIX features"

This reverts commit 7aebec8db1a6f231a2a93ec82872afadb8ed3879.
As per the discussion on the mailing list.

libroot: Undefine constants for unsupported POSIX features

Haiku does not yet support certain features related to POSIX threads.
Constants used to test for the presence of these features should
therefore be left undefined, according to the POSIX spec, but are
currently set to -1. This can cause software built on Haiku to
incorrectly detect the presence of these features.

* unistd.h: Undefine _POSIX_THREAD_ATTR_STACKADDR,
_POSIX_THREAD_PRIORITY_SCHEDULING feature constants.
* conf.cpp: __sysconf: Return -1 for unsupported features.

* Replaced the dummy implementations of the <grp.h> and <pwd.h>
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 support for chroot:
- 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().

* Implemented some basics for supplementary groups support:
- 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.

* Added real, effective and saved set- user and group IDs to the team
structure. They are properly inherited and updated on
fork(), load_image(), and exec().
* Implemented the get[e]{u,g}id(), set[[r]e]{u,g}id() family for real.
* getgroups() also calls the kernel now, but only returns the effective
group ID. Supplementary groups support is still missing.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34288 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented POSIX.1-2008 functions unlinkat(), symlinkat(), mkdirat(),
utimensat(), and futimens().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34010 a95241bf-73f2-0310-859d-f6bbb57e9c96

Moved the POSIX *at() functions and AT_* macros out of the default namespace
as long as the full set hasn't been implemented. They are guarded by the
B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT macro until then. Fixes the build.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33990 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added readlinkat().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33978 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixing #3460:
* resolved a couple of redundant function declaration in our public headers
* adjusted zipomatic accordingly - everything else built fine

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31938 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed value of _POSIX_VDISABLE. cc_t is unsigned in Haiku. ATM we don't
support _POSIX_VDISABLE at all. It's even questionable whether the value
(unsigned char)-2 is a good choice.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29137 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fix typo. Thanks mjw!


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26132 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some more funny sysconf()...


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25627 a95241bf-73f2-0310-859d-f6bbb57e9c96

- factored out [f]pathconf().
- *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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25625 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some more [f]pathconf() names, not yet handled. filesizebits returns 64 though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25623 a95241bf-73f2-0310-859d-f6bbb57e9c96

Let's pretend we support POSIX threads.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25588 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Andreas Faerber:
Replaced single-line comments by multi-line comments for ANSI C
compliance.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25433 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed some misunderstanding regarding the _POSIX_* macros. They are
not supposed to be passed to pathconf() or sysconf().
* Added POSIX semaphore related macros.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25361 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add _SC_PAGE_SIZE sysconf().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24850 a95241bf-73f2-0310-859d-f6bbb57e9c96

Applied patch by James Woodcock:
* Implemented POSIX getpagesize() function in libroot.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24763 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced the dummy implementations of the <grp.h> and <pwd.h>
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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24750 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented support for chroot:
- 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

* Implemented some basics for supplementary groups support:
- 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24669 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added real, effective and saved set- user and group IDs to the team
structure. They are properly inherited and updated on
fork(), load_image(), and exec().
* Implemented the get[e]{u,g}id(), set[[r]e]{u,g}id() family for real.
* getgroups() also calls the kernel now, but only returns the effective
group ID. Supplementary groups support is still missing.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24359 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Vasilis Kaoutsis: Added and implemented lockf() using fcntl() locking.
Small change and notes on standard compliance by myself.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22628 a95241bf-73f2-0310-859d-f6bbb57e9c96

added an empty implementation of confstr()


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21810 a95241bf-73f2-0310-859d-f6bbb57e9c96

setpgrp() returns a pid_t, not an int.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20008 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added vfork() as a wrapper to fork().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19491 a95241bf-73f2-0310-859d-f6bbb57e9c96

added posix_gnu_string
added more posix definitions


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16813 a95241bf-73f2-0310-859d-f6bbb57e9c96

ualarm()'s arguments are actually useconds_t, too.
Fixed implementation of ualarm() to support larger values.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14890 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed alarm(), ualarm(), and sleep() return codes - "uint" is not a POSIX type.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14888 a95241bf-73f2-0310-859d-f6bbb57e9c96

added seteuid and setegid


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14701 a95241bf-73f2-0310-859d-f6bbb57e9c96

tcsetpgrp() and tcgetpgrp() are actually defined in unistd.h, not termios.h.
Implemented them and moved them to unistd/terminal.c - not yet tested, though,
but should work. As a side effect, the TTY should now send signals.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12034 a95241bf-73f2-0310-859d-f6bbb57e9c96

added setpgrp


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11573 a95241bf-73f2-0310-859d-f6bbb57e9c96

- removed ctermid() and cuserid(), which live in stdio.h
- removed system(), which lives in stdlib.h


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9905 a95241bf-73f2-0310-859d-f6bbb57e9c96

We don't support the BeOS mount API.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9869 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added missing process prototypes.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9344 a95241bf-73f2-0310-859d-f6bbb57e9c96

Minor cleanups.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9054 a95241bf-73f2-0310-859d-f6bbb57e9c96

Unlike alarm(), ualarm() has actually two arguments.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8785 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some changes for an independent header system - added missing function
prototypes (and those commented out), to keep the whole project be compilable
and usable on BeOS.
Fixed a bug in fcntl.h (definition for O_DIRECT), added new O_MOUNT.
Added prototypes and "struct tm" to time.h.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1619 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added headers for fnmatch, glob, and pwd stuff.
Uncomment some functions in unistd.h which glob is using.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1419 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added a preliminary sys/types.h that just includes ktypes.h for now.
Changed other headers to include sys/types.h rather than ktypes.h.
Added a license reference at the beginning of those files.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@840 a95241bf-73f2-0310-859d-f6bbb57e9c96

The fs interface functions should now return a "status_t" rather than an "int".
Added syscalls for, and implemented sys_create_link(), sys_remove_dir().
Implemented link(), unlink(), rmdir().
Fixed the inconsistent path buffer handling in the user|sys vfs functions; the
path buffer is now exactly SYS_MAX_PATH_LEN from userland (incl. terminating
null byte).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@748 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented some more calls in unistd.h.
Replaced the unused syscall for getdtablesize() with one for access().
Implemented sys_access() and added it to the file system interface.
Removed the fs function interface from vfs.h.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@738 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added mount.c, implementation of mount() and unmount().


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@670 a95241bf-73f2-0310-859d-f6bbb57e9c96

Replaced opendir.c with directory.c, implemented chdir(), fchdir(), and
getcwd().
Introduced new xyz(int fd, char *path, ...) style of functions for
sys_setcwd(), and sys_write_stat().
Added missing sys_fstat(). Removed duplicated prototypes in syscalls.h
Fixed some minor bugs.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@669 a95241bf-73f2-0310-859d-f6bbb57e9c96

getdtablesize() no longer needs a syscall.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@667 a95241bf-73f2-0310-859d-f6bbb57e9c96

New BeOS-like unistd.h file.
All unimplemented functions are commented out for now - but that has to
change, of course.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@665 a95241bf-73f2-0310-859d-f6bbb57e9c96
