way how to solve this, feel free to speak, I haven't found anything :).

at all, and assumes a fixed and wrong number of preallocated GDT entries.
Implemented TLS: there is one GDT entry per CPU. If a context switch happens,
the FS register of the new thread is set to the matching GDT, and the GDT is
changed so that it points to the current thread's TLS storage area.
This area currently resides unsafely at the bottom of the user stack - for
some reason I could not figure out, it doesn't even work correctly most of
the time (it segfaults when accessing a slot via FS). I've added a ToDo item
explaining the situation - hopefully I have more ideas when I slept a bit more...
The GDT is now no longer static in arch_cpu.c and has been renamed from gdt to
gGDT. It's now also referenced in arch_thread.c, and it would make sense for
arch_selector.c to use it as well (instead of another local copy).
arch_cpu_init2() now uses the set_tss_descriptor() inline function and the
TSS_BASE_SEGMENT macro to set up the TSS section. It now also sets up the
TLS segment descriptors (as TSS, one entry per CPU).
Since I removed desc_table from the headers (the GDT is now a (segment_descriptor *)),
I added it locally to arch_int.c.
i386_enter_uspace() now don't set the FS register to 0x23 anymore, since it's
now already set correctly at the end of arch_thread_context_switch().
Some clean-ups.

I was too lazy to revert that little change back, so that I would be able
to write this short paragraph explaining what I've done.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2364 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved the tss_descriptor structure to descriptor.h, updated it to be a
segment_descriptor structure, and provided inlines for set_tss_descriptor(),
set_segment_descriptor(), set_segment_descriptor_base(), and
clear_segment_descriptor().
Also added defines for the different privilege levels and descriptor types.
Removed the unusused and incorrect TSS definition, introduced new
TSS_BASE_SEGMENT and TLS_BASE_SEGMENT macros.
Removed include of arch/cpu.h in arch_cpu.h.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2360 a95241bf-73f2-0310-859d-f6bbb57e9c96
returned a (void *) instead of a (void **)).
Added TLS_MAX_KEYS macro, and a comment.
Cleanup.

The correctness of max_number_of_levels is now checked in Find().
Added a class NodeChecker which checks the integrity of the specified node
when the object is destructed (via new method bplustree_node::CheckIntegrity());
now used in Remove() and Insert().

to handle this.

code and made it much simpler (it now just uses a stack of path names
instead of this complex doubly-linked module_iterator_dir list).
Now works together with the rest of the code without making any problems.
Added a module_test() function which iterates over all existing modules.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2149 a95241bf-73f2-0310-859d-f6bbb57e9c96

Changed fd.h inlines because team->ioctx is now team->io_context.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2140 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a "page_faults_allowed" field in the thread structure.

bfs_open_dir() now accepts again all containers, because bfs_open_index_dir()
is using it, too (too bad when you forgot about your own code).

compareKeys() will now return -1 if it didn't know the type to compare.

thread_exit() for now prints a warning if it was called with interrupts
disabled.
Fixed a bug in thread_exit2() that restored the interrupts too early,
instead of simply enabling them (and restoring them later) [found by
Marcus O. great debug additions].
Fixes for the khash changes.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2119 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now the d_reclen field of struct dirent is correctly calculated in all
file systems (read_dir() function).

leak fixed, some other bugs fixed, removed the global queues as there weren't
needed and used at all, moved to the other hash table implementation
(because the new_hash_table stuff was buggy). Should really work okay now :-)
Added the last missing function get_next_loaded_module_name() - I am not
sure the Be version works this way, but we could easily change that after
actually having found out how that one is really working.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2113 a95241bf-73f2-0310-859d-f6bbb57e9c96
implementation that was buggy, not very flexible, and incomplete.
Changed some variable types, and function names.

is d_reclen which points out that this field is not the name length but
the one of the whole record (this is also handled incorrectly by the kernel
file systems right now).

Most probably these are used by the kernel to identify changes in a shared
library or something like this.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2088 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bigger race condition when matching against the name index.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2085 a95241bf-73f2-0310-859d-f6bbb57e9c96
The inode is now locked in bfs_close() (when the indices are updated).
Moved the special cases for INODE_NO_CACHE and INODE_CHKBFS_RUNNING into
bfs_free_cookie() - should probably do that with the index update as well.
Updated some comments.

to the provided buffer.
Inode::Name() no longer locks the small_data region anymore.
Added ASSERTs that the small_data region is locked for the methods requiring
that.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2083 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now supports fixing errors as well (and introduced a new option -e to fix
some additional errors).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2069 a95241bf-73f2-0310-859d-f6bbb57e9c96
though (boy, I am so lazy...).
Cleaned up the Jamfile a bit.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2065 a95241bf-73f2-0310-859d-f6bbb57e9c96
bfs_read_vnode() will now wait for half a second at maximum until it returns
the B_BUSY error (so that live queries will like it better).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2058 a95241bf-73f2-0310-859d-f6bbb57e9c96
instead calls Inode::Free().
If INODE_DONT_FREE_SPACE was set, bfs_remove_vnode() forgot to delete the
inode before returning B_OK.
bfs_read_vnode() will now return the exact error Inode::InitCheck() returned.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2056 a95241bf-73f2-0310-859d-f6bbb57e9c96
to the InodeAllocator class (initialization of the inode, tree creation for
containers).
The InodeAllocator class now frees all the space the inode occupies, including
the B+tree if it's a container (by calling the new Inode::Free() method).
Inode::Free() implementation (logic removed from bfs_remove_vnode()).
Now secures the inode from being loaded by setting the INODE_NOT_READY flag
(completely handled by the InodeAllocator class).
The inode is now removed from its parent if something went wrong after it
had been added.
Utilizes the new BPlusTree::Remove() method where appropriate.
Inode::GetAttribute() now checks if the inode opened is really an attribute.
Inode::InitCheck() now fails with B_BUSY if the INODE_NOT_READY flag is set.
InodeAllocator::Keep() now writes back the inode.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2055 a95241bf-73f2-0310-859d-f6bbb57e9c96
also the numBlocks parameter is ASSERTed - when compiled with DEBUG turned
off, BFS will enter the kernel debugger in this case (through the use of
the DIE() macro).
Same for AllocationBlock::Free() (but the 0xffff mode was already removed
there).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2053 a95241bf-73f2-0310-859d-f6bbb57e9c96
allocation group as the inode, if possible.
Moved the group used blocks info maintaining code into AllocationGroup::Allocate()
and AllocationGroup::Free() (instead of letting the BlockAllocator class do
the work).
Removed the buggy and useless extra 0xffff mode for AllocationBlock::Allocate()
and AllocationBlock::Free(), both methods now ASSERT their parameter range.
Changed some comments, style cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2052 a95241bf-73f2-0310-859d-f6bbb57e9c96
of the stream (so the "chkbfs" functionality is complete now).
Fixed wrong block number report in BlockAllocator::CheckBlockRun(), blocks are
now printed out in absolute numbers (not allocation_group relative anymore).
Use Inode::IsContainer() where necessary instead of Inode::IsDirectory().
Fixed a big and nasty bug in AllocationBlock::SetTo(): the number of bits in
a block could be calculated wrong for a partial allocation group which need
more than one block in the bitmap - hopefully, that was the last remaining
big bug in the block allocator.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2032 a95241bf-73f2-0310-859d-f6bbb57e9c96
inode locked if the _inode parameter is passed.
Makes some more use of the new type identificators.
Symlinks are no longer added to the "size" index (compatibility with BFS, and it also
makes much more sense).
Now sets S_STR_INDEX for directories, if no index type was set (again, compatibility
issue with BFS).
Fixed a bug in the Inode::GrowStream() method in the double indirect region.
Some style updates.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2030 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed Inode::IsDirectory() to Inode::IsContainer() (since it is also true
for index/attribute directories).
Introduced a new Inode::IsDirectory() that only checks for real and standard
directories. Let's hope I've fixed more bugs with that than introduced new
ones...
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2029 a95241bf-73f2-0310-859d-f6bbb57e9c96
The only functional change is that bfs_rename() now checks for '/' in the
target name (the VFS should do those things, but you never know as long
you haven't written it yourself :).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2028 a95241bf-73f2-0310-859d-f6bbb57e9c96
via the private ioctls defined in bfs_control.h.
Detects all kinds of errors, and can correct most of them. It doesn't fix
any errors in the b+trees (like the ones created by an earlier version
of the BPlusTree class ;-), and it also can't fix the "blocks are already set"
error, which occurs if more than one file claims a particular block (or
range of blocks) for itself.
The double indirect data range is not yet supported, so use with care, or
run the original chkbfs afterwards to fix any errors because of that.
Might not yet analyze 100% correct (shows way to many errors for my tastes...).
A "chkbfs" command will be made available shortly.
