could cause before.

potential bug if MAIN_STACK_SIZE and STACK_SIZE would have been different.

read over two blocks, some memory behind that memory could be trashed.

waiting on the write semaphore).
The write functions didn't change the buffer address on a partial write
which could lead to corruption in the pipe data.

Fixed a warning that popped up if TRACE_VM was defined.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9110 a95241bf-73f2-0310-859d-f6bbb57e9c96
This fixes the build as unistd.h defined sleep() as well.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9108 a95241bf-73f2-0310-859d-f6bbb57e9c96
It now prints a warning if the device driver doesn't handle iovecs correctly.
Again, this could lead to very strange behaviour.

name of the node.
devfs_read_stat() now (presumably temporary) sets the size of the device
for partitions and reports a block device rather than a character device
if the size unequals zero.

* Turned sMountOpMutex into a recursive lock.
* Re-inserted sMountOpLock locking in vnode_path_to_vnode(). It doesn't
deadlock on mounting anymore. :-P
* Added a check in fs_mount(), whether the mount point is a directory. If
it wasn't, in general it wouldn't be possible to get its parent
directory.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8993 a95241bf-73f2-0310-859d-f6bbb57e9c96
why that was there before. Thanks to Ingo for pointing this out.

extensions/ directory - which will contain glibc specific additions
to the POSIX standard (getopt() is here because of getopt_long() etc.).
Also added obstack functions.
Added wcsmbs to the build.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8969 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now maintains uid/gid/mode, modification and creation time for all nodes.
Implemented rootfs_write_stat() completely. rootfs_read_stat() now fills
in all required values.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8962 a95241bf-73f2-0310-859d-f6bbb57e9c96
time in st_mtime.
rootfs_write_stat() now properly locks the node access.
Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8960 a95241bf-73f2-0310-859d-f6bbb57e9c96
permissions are not tested, though.
Removed the STREAM_TYPE_ constants.
Now maintains a modification and creation time for all nodes.
Implemented rootfs_write_stat() completely. rootfs_read_stat() now fills
in all required values.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8959 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added note to dirfd() that it should be excluded from the kernel build
once the build system allows this.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8958 a95241bf-73f2-0310-859d-f6bbb57e9c96
This normally resides in the posix/ directory in the glibc source repository.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8944 a95241bf-73f2-0310-859d-f6bbb57e9c96
console driver now clears the screen when it's initialized.
This improves the first impression of the standard boot process when
booting in text mode (which currently happens when you press "escape"
in the early boot stage).

IDE drivers :-)) don't respect the total amount of bytes to be read in the
former readv() (now read_pages()) call. This can potentially fix all sorts
of strange errors in userland :)
Fixed the debug build.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8938 a95241bf-73f2-0310-859d-f6bbb57e9c96
recreates a race condition, having it here breaks the kernel as fs_mount()
calls this function and already holds the mutex.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8936 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now panics if devfs_publish_device() fails.
Tracing can now be turned on and off (it's now completely silent in normal operation).
Some cleanups.

unmounted.
* Clarified a comment in fs_mount().
* Added a bit of documentation regarding the mutexes and the basic vnode
functions.

available at /bin/sh (a symlink will do). Unfortunately there's some
problem with our shell that causes it to crash in most cases. :-(

always do. More often than not one gets page faults. As it happens
sometimes even before anything meaty has been done at all
(e.g. in main()->init_statements()->shell_var_set_text()->
shell_value_init_text()->malloc()), I believe that's a problem not caused
by me. And I wasn't able to track it down.

Userland. It must always set the d_pdev and d_pino fields and, if the
Entry refers to a mount point even replace d_dev and d_ino.
* Added a TODO comment to entry_ref_to_vnode(). It should take care of
mount points, as vnode_path_to_vnode() does, I believe. Will verify
and fix that next.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8921 a95241bf-73f2-0310-859d-f6bbb57e9c96
this is the one thing most likely to fail - it now also handles this case
gracefully instead of dying.
Small cleanup, cleared some other ToDos: some user functions now delete
the area when they could not copy the target address.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8911 a95241bf-73f2-0310-859d-f6bbb57e9c96
leaving the tags Qt style though. That's a bit weird, but that's the
way Axel likes it, and we want to keep him happy, don't we? ;-P
* The common_[path_]read_stat() now fills in st_dev and st_ino in the
result stat structure after the FS had its go. The information is
readily available in the VFS, so why bother the FSs. In fact devfs
didn't (and still doesn't) fill in st_dev which gave dev_for_path()
some head ache.
* Modified _user_open_parent_dir() to accept a NULL buffer for the
entry name and added a doxygen comment for it.
df now works properly on Haiku (save that printf() doesn't support
floating point numbers at the moment).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8898 a95241bf-73f2-0310-859d-f6bbb57e9c96
always also access it through the devfs_vnode. This also solves an issue
in devfs_read() where an access of a cookie->stream would crash the
kernel, since cookie->stream was not set in devfs_open().
* devfs_open() now doesn't fail for directories and symlinks anymore.
That prevented BNode to work for devfs dirs and symlinks.

`.'. This fixes the _kern_open_parent_dir() syscall for the root directory.
I realized, that rootfs_read_dir() doesn't return the entries `.' and `..',
unlike Be's rootfs. Shall I add those, Axel?
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8895 a95241bf-73f2-0310-859d-f6bbb57e9c96
This has the advantage that the device can now be access in the right context.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8876 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed the calculation of the amount of bytes read in bootfs_read_pages().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8874 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added an vfs_get_cookie_from_fd() call to at least temporarily support the
cookie as in the original devfs (not sure yet how this changes).
Implemented vfs_get_file_map() which calls the corresponding FS function.
Moved vfs_get_vnode_cache() around.
vfs_get_vnode() temporarily does its job unlocked - its only to be used (safely)
from within the file cache, but this should definitely be done better.
Fixed a bug in get_vnode_name() - it did not support getting the name of
a root directory; it didn't pass the call through to the parent file system.
Fixed a bug in _user_entry_ref_to_path() which would add another "/" for
files immediately under the root (ie. "df" showed "//boot" as mount point
for the boot partition).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8873 a95241bf-73f2-0310-859d-f6bbb57e9c96
_KERNEL_MODE is already defined when using kernel build rules, no need
to do it here manually.

couldn't be satisfied completely (ie. because the file size is not a
multiple of the page size).
It's no longer necessary to implement this functionality in the file systems.

node and its interface directly. It will also convert the old interface into
the new one to simplify the implementation.
devfs_open() now contains the former pnp_devfs_open() as well.
devfs_publish_device() no longer passes the "ident" parameter to its lower
layers - it will be removed.
The VM fs interface has changed to better match the one of the device interface.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8849 a95241bf-73f2-0310-859d-f6bbb57e9c96

Not yet used - might be used instead of the vm_cache page caching for the file cache.
