44c3f5c188 Clean up the mess added in hrev43461 and solve it differently.
* Define a MEMALIGN macro that is either just defined to malloc() or
  to the actual memalign() depending on where KMessage is used. We only
  use memalign() inside the kernel and libroot.
* Add a comment to the macro explaining that this allows the use of
  special heap implementations that might return unaligned buffers for
  debugging purposes.

e339322a88 Fix hrev43405 by moving the reference above the autolocker.
The change in hrev43405 wasn't correct, as it put the reference
object definition after the one of the corresponding locker, causing
the reference to be released before the unlock would happen.

Finally fixes #8187. Thanks Ingo for pointing that out.

5585262bb1 Revert hrev43455 and instead just align the size.
While this isn't really correct, it works for the use case it is
intended and doesn't open the can of worms we get when trying to do
memalign() across platforms (due to build tools use of KMessage).

82929f8a76 Add a simplistic memalign() to the runtime_loader heap.
As KMessage now makes use of memalign() the simple heap in the
runtime_loader needs to provide that as well. Fixes build.

9a87646122 Only free the old buffer if we owned it and set owning flag.
* If we cloned the buffer due to misalignment, only free the old buffer
  if we actually own it (i.e. if it was allocated by us).
* Set the KMESSAGE_OWNS_BUFFER flag after cloning the buffer. Previously
  the buffer was leaked in the clone case.

d0aa07489c Ensure proper alignment instead of just checking for it.
* If there is an alignment requirement then better use memalign() to
  make sure that it is met.
* Since the BMessageAdapter possibly sets a buffer directly, make a
  properly aligned copy of the buffer if it happens to be misaligned.

97680106f0 Add a userland version of the guarded heap to libroot_debug.
The guarded heap uses mprotect() to protect freed/unallocated pages so
that any access to such a page results in a segfault. It also installs
a segfault handler that in such an event prints some info about the
accessed page and then calls the debugger with a meaningful message.

It implements the same interface as the debug heap so it can simply be
swapped out by changing the Jamfile. As it doesn't support most of the
extra debug features (wall checking is obviously superfluous, but it
also doesn't help in leak checking) and as it is hugely space
inefficient I left it disabled for now.

ded69b4c3a Only the to be protected range needs to be non-wired.
When setting memory protection, only ensure/wait for the range that
needs to be protected to not be wired instead of requiering the whole
area to be non-wired. The memory protection is done page wise and
having some parts of the area wired shouldn't preclude other parts to
be protected.

da329fc012 Add missing asignment of return code in wait_for_thread_etc().
While it was detected that the thread is in the destruction phase
and that it was necessary to wait and then have a valid status code
in the death entry, that status code wasn't actually returned. This
lead to uninitialized values for the return code even though
wait_for_thread[_etc]() would return B_OK.

2872aba0a7 Fix missing reference to the old group with lock still held.
Removing the team from the group may have released the last reference
to the group and freed it. Since we still have a locker on that group
it would later crash on unlock, therefore we need a reference to the
old group before removing the team from it.

01eb710a91 Use a free list to make the guarded heap perform less horribly.
Pages that are freed are added to the tail of the list while allocation
candidates are taken from the head. Therefore pages that have been free
the longest are preferred, making immediate re-use less likely.

Also avoid looking for pages if the free count already tells that the
allocation can't be fulfilled.

5cbe06f482 Allow replacing the object cache with the guarded heap.
This allows to use the debug features of the guarded heap also on
allocations made through the object cache API. This is obivously
horrible for performance and uses up huge amounts of memory, so the
initial and grow sizes are adjusted accordingly.

Note that this is a rather simple hack, using the object_cache pointer
to transport the allocation size. The alignment is neglected completely.

01762bd57f Fix possibly harmful use of stale pointer in edge case.
The call to _MakeSpace() may move the extent data from the indirect
array (kept in a heap allocation) to the direct one kept inside the
class. In that case the lastExtent pointer would become stale and
further use of it would've lead to suboptimal extents in the best case
to reading/writing at the wrong point in files and possibly corruption
of another allocation in the worst (both unlikely though).

To mitigate that we now re-initialize the pointer to the correct location
if we hit the cache limit.

Also made the use of the start variable more understandable. Instaed of
decrementing it (possibly wrapping) when an extent wasn't going to be
used and later adding the vector index again, just increment whenever
we actually move to the next extent.

For bad things to happen a few conditions needed to come together though:
1. There needed to be multiple vectors that could be combined with the
existing last extent.
2. There first needed to be more extents than the cache limit and that
number then had to decrease below the cache limit again.
3. The memory needed to stay intact after being freed up until after the
evaluation (or similar enough data had to be written to it).

At least the last one was guaranteed to not be true anymore since we
re-introduced overwritting freed memory with 0xdeadbeef in the slab,
therefore nastily hiding this. I'm not sure that the first condition is
ever met either (probably the vectors are combined beforehand so that
there never are multiple adjacent ones) at least for the normal use case
(the page writer writing back pages). I was at least unable to reproduce
an actual file corruption in my testing.

Just the out of bounds access to the stale pointer happened rather easily
though and is now at least fixed.

e62d9911ea Allocate as much as is later read, didn't do harm though.
Further in the process the flat argument size is rounded up, but the
actual allocation was done with the unaligned size causing an access
beyond the allocation when later copying the flat arguments. It didn't
do any actual harm as the block sizes of our allocator(s) use elements
that have at least such an alignment.

1fe24d0cd0 Add heap with guard pages to detect out of bound reads/writes.
This is a very simple heap implementation that allocates memory so that
the end of each allocation always coincides with a page end and is
followed by a guard page which is marked non-present. Out of bounds
access (both read and write) therefore cause a crash (unhandled page
fault).

Note that this allocator is neither speed nor space efficient, indeed it
wastes huge amounts of pages and address space so it is quite easy to
hit limits. It is intended as a pure debug feature.

7418dbd908 Introduce debug page wise kernel area protection functions.
This adds a pair of functions vm_prepare_kernel_area_debug_protection()
and vm_set_kernel_area_debug_protection() to set a kernel area up for
page wise protection and to actually protect individual pages
respectively.

It was already possible to read and write protect full areas via area
protection flags and not mapping any actual pages. For areas that
actually have mapped pages this doesn't work however as no fault, at
which the permissions could be checked, is generated on access.

These new functions use the debug helpers of the translation map to mark
individual pages as non-present without unmapping them. This allows them
to be "protected", i.e. causing a fault on read and write access. As they
aren't actually unmapped they can later be marked present again.

Note that these are debug helpers and have quite a few restrictions as
described in the comment above the function and is only useful for some
very specific and constrained use cases.

643cf35ee8 Add debug helper functions to mark pages present.
They can be used to mark pages as present/non-present without actually
unmapping them. Marking pages as non-present causes every access to
fault. We can use that for debugging as it allows us to "read protect"
individual kernel pages.

a139657921 Tracking info wasn't always retrieved with the cache locked.
Getting the object slab does a hash lookup which needs to be protected
by the cache lock. Otherwise the hash table may be resized or otherwise
modified while we do the lookup, leading to errors.

79f0056002 Fix virtual 8086 mode to properly account for TLS.
* The vm86 code or the code running in virtual 8086 mode may clobber the
  %fs register that we use for the CPU dependent thread local storage
  (TLS). Previously the vm86 code would simply restore %fs on exit, but
  this doesn't always work. If the thread got unscheduled while running
  in virtual 8086 mode and was then rescheduled on a different CPU, the
  vm86 exit code would restore the %fs register with the TLS value of
  the old CPU, causing anything using TLS in userland to crash later on.
  Instead we skip the %fs register restore on exit (as do the other
  interrupt return functions) and explicitly update the potentially
  clobbered %fs by calling x86_set_tls_context(). This will repopulate
  the %fs register with the TLS value for the right CPU. Fixes #8068.

* Made the static set_tls_context() into x86_set_tls_context() and made
  it available to others to faciliate the above.

* Sync the vm86 specific interrupt code with the changes from hrev23370,
  using the iframe pop macro to properly return. Previously what was
  pushed in int_bottom wasn't poped on return.

* Account for the time update macro resetting the in_kernel flag and
  reset it to 1, as we aren't actually returning to userland. This
  didn't cause any harm though as only the time tracking is using that
  flag so far.

* Some minor cleanup.

We don't need to explicitly track the covered/covering nodes per mount

54e721afeb Add support for bind-mounting directories
* Add support function vfs_get_mount_point(), so a file system can get
  its own mount point (i.e. the node it covers). Re-added
  fs_mount::covers_vnode for that purpose -- the root node isn't know to
  the VFS before the mount() hook returns.
* Add function vfs_bind_mount_directory() which bind-mounts a directory
  to another. The Vnode::covers/covered_by mechanism is used, so this
  isn't true bind-mounting, but sufficient for what we need ATM and
  cheaper as well. The vnodes connected thus aren't tracked yet, which
  is needed for undoing the connection when unmounting.
* get_vnode_name(): Don't use dir_read() to read the directory. Since we
  have already resolved vnode to the covered vnode, we don't want the
  dirents to be "fixed" to refer to the covering nodes. Such a vnode
  simply wouldn't be found.

that are but don't take effect as long as they are ignored by the build
system into the master.

Summary of changes:
* Introduce private header <directories.h> with constants for a good
  deal of paths that should usually be retrieved via find_directory().
* Replace hard-coded paths by using find_directory() or the
  <directories.h> constants (e.g. in drivers and the kernel).
* Add find_directory() constants needed for package management.
* Add __HAIKU_ABI_NAME and B_HAIKU_ABI_NAME macros.

  DeskBarUtils.* -> DeskbarUtils.*
* Change deskbar menu settings directory from ~/config/be to

* this avoids spurious errno changes leaking into application code,

I spend a couple of hours hunting down the behavioural difference
between gcc2- and gcc4-builds and it turns out that the reason for that
is that gcc4's libstdc++-code initializes its own locale data via the
POSIX calls, which trigger (correct) errno value changes, which were the
ones leaking into application code.

8a5fb91c07 Stricter tests for PCI bridges at interrupt routing.
Validate the candidate child device a bit more by checking the device ID
and the base and subclass of the device. We don't even know if the child
is still on the PCI bus and some firmware may mark disabled devices by
simply invalidating one of these values. Possibly fixes #8111.

Added TODO concerning that we might not want to fail at all since we
ensure that we matched all devices after routing preparation at which
state we would notice any missing child devices anyway.

added up and later subtracted from the sNumPages, resulting in a wrong
max page count. Also due to the fixed removal of non existing page
ranges the actually available memory would usually not be the amount
set via LIMIT_AVAILABLE_MEMORY.

Instead we now calculate the available memory when going through the
physical memory ranges and limit/exit as soon as we've reached the
desired amount of available memory (also ignoring further non-existing
pages).

c12f51264b Ensure the sanity of the stats returned, make the TODO a Note.
* Ensure that we don't underflow the used_pages count and that used
  + cached pages don't overflow max_pages. As there is no locking the
  values may change while we read them so that such situations could
  arise.
* Make the TODO about the missing locking into a Note explaining the
  above, as it is not really worth adding locking here. The stats are
  only informational.

3733c51d38 Fix the computation of used memory and add a TODO.
* The altered used pages calculation of hrev43168 wasn't correct, as
  the inactive page queue may (validly) contain mapped pages as well.
  Those would then get counted twice (as they are included in
  gMappedPagesCount already).
  Instead we calculate the used pages from the total page count, minus
  everything we account for otherwise. Doing it this way is possible
  without introducing any additional counters, as all the counts to
  subtract are already present (as opposed to some of the ones that
  would be needed for adding the counts up). Fixes #8109.
* Added TODO regarding the problem of not locking any of the counters
  which runs the risk of them getting modified while we haven't yet read
  all of them.

fc2d7cb04d * Introduce {reserve|allocate|free}_io_interrupt_vectors() that can generically
be used to mark certain io interrupt vectors as reserved and to allocate from
  the still free ones. It is a kernel private API for now though.
* Make the MSI code use that functionality instead of implementing its own which
  slims it down considerably and also removes quite a bit of hardcoded knowledge
  about the interrupt layout that didn't really belong there.
* Mark the various in-use interrupts as reserved from the components that
  actually know about them (PIC, IO-APIC, SMP, APIC timer and interrupt setup).

2a77028057 Relax ensure_all_functions_matched() to assume no interrupt use when a device
has no routing information but wasn't configured by the BIOS either. The
function will now only panic if a device that was previously configured would
not be so anymore after enabling the IO-APIC. Fixes #7971.

  As-is the boot loader wouldn't start on G5 systems because
  OpenFirmware memory base addresses are stored as two 32-bit
  unsigned int 'cells' vs one 32-bit unsigned int 'cell' on G3/G4.
  I removed the static struct and replaced it with a template
  and pass uint32 or uint64 depending on the address cell size.

961a96a987 Optimize the configuration of the port heap. Previously the max bin size was
512 bytes with a heap page of 2048 bytes resulting in excessive waste for
allocations between 512 and 1023 bytes. Also tune the requested alignment so
that sizeof(port_message) (currently 28 bytes) can occupy one allocation unit
without waste.

3fb17998a7 When resizing an area that has individual page protections (set via mprotect),
we have to enlarge/shrink the array that holds them and assign a protection
value for the additional pages as necessary. Otherwise we'll access invalid
memory when looking up page protections for enlarged areas and get random
protection values.
Experienced with QEMU that sets page protections via mprotect on heap memory.
When the heap was later enlarged, write access to the additional memory would
result in permission denied errors and crashes.

14c345e147 * Revert r42319 as it introduces a race condition when entering the kernel
debugger. As sInDebugger is already > 0 when the first CPU enters KDL, code
  from other CPUs might see debug_debugger_running() == true already before they
  enter the debugger.
* Instead, move the sDebuggerOnCPU setting out of the debugger loop and hold the
  value until after calling exit_kernel_debugger() so that the exit hooks still
  see debug_debugger_running() == true.
* Also avoid calling exit_kernel_debugger() when we've been called recursively
  (previousCPU != -1). Previously the exit hooks would've been called and the
  debugger state reset erroneously. To balance the missing decrement of
  sInDebugger in that case we decrement sInDebugger in enter_kernel_debugger()
  also when detecting the recursion case.

3214710036 Use sInDebugger instead of sDebuggerOnCPU to determine if the debugger is
running. The former has a broader scope and lasts until the debugger exit is
actually done whereas the latter is already reset when the inner loop is exited.
This fixes the issue Ingo saw where the USB physical memory manager wasn't able
to free resources used for the debug transfer. It has reserved debug memory that
it uses depending on debug_debugger_running() and was therefore confused when
it returned false when called from the kernel debugger module exit hook.

cd3e02ca1e * Growing the port heap by adding new areas was broken in various ways. For one
the acquired quota in sTotalSpaceInUse wasn't released in all cases leading to
  it eventually reaching the limit (after a _very_ long time though, so this is
  more theoretical than anything else). The sAllocatingArea flag wasn't reset in
  the case that an area was already added in the meantime, resulting in no
  further growing being possible. Then there were race conditions between
  waiting for space to become available and the situations which made that space
  available (freeing port_messages and adding new areas).
* Fix these race conditions by using a mutex (sPortQuotaLock) to protect the
  various quota and allocation related variables. Instead removed the atomic_*
  operations that were previously used.
* Had to move some static functions around.

Should make port heap growing more robust, even though in normal use you'll
likely never encounter it...

f84387d6c4 _user_initialize_partition(): After performing the operation don't set the new
disk system, if the partition already has a disk system set. This can happen
when the disk system's initialization function is lazy and just lets the DDM
rescan the partition. In bad cases the previous disk system has a higher
priority than the new one and, if its on-disk structures have not been
destroyed, it will win the rescan. Not setting the disk system in such cases at
least leaves the partition object in a consistent state.

* Added "Display current boot loader log" item to the "Debug Options" boot
  loader menu. It displays what the boot loader has logged so far. Might be
  interesting for early boot issues when serial debugging is not possible.

73df2f2086 * Add validation of the RSDP checksums.
* If we detect ACPI 2.0 or higher, the spec says we should use the XSDT rather
  than the RSDT. Attempt to do so, falling back to the RSDT if the former fails
  to be mapped/validated.
* Refactored acpi_find_table into a templated version to account for the fact
  that the XSDT exports different pointer widths for its links to other tables
  than the RSDT.

36dc99a323 Add private get_memory_properties() syscall which allows one to retrieve the
address protection bits as well as the wiring flags for an arbitrary address
in a team's address space. Will be used in the debugger for the purposes
of the memory inspector/editor, in order to determine whether it can in fact
allow editing for the currently inspected address range.

8bcc50c336 * Added arch_debug_blue_screen_try_getchar() and arch_debug_serial_try_getchar()
which don't wait for a character, but return -1 when no character is
  available ATM. Implemented correctly for x86 only.
* Changed the semantics of the debugger_module_info::debugger_getchar() hook.
  It is supposed to return immediately now.
* Adjusted usb_keyboard accordingly. Hacked UHCI's debug_process_transfer() to
  achieve that. It does now start, check, or cancel a transfer. Split
  UHCI::ProcessDebugTransfer() into StartDebugTransfer(), and
  CheckDebugTransfer() accordingly, and also added a CancelDebugTransfer().
  The latter seems to have issues. Michael, please have a look. I have no clue
  what I'm doing. :-)
* Adjusted kgetc() to poll all possible inputs using the new
  functions/semantics. This allows to use any input (USB, PS/2, serial) in KDL.
* Removed the no longer needed "serial_input" command.
* read_line(): Also support 0x7f as backspace code. That's what xterm sends.

c4b692da1a Revert r42105. The rsdt_length field on the rsdp structure we have declared is
actually misleading, since it specifies the length of the xsdt rather than the rsdt. Furthermore, it is only available if the BIOS reports ACPI version 2.0 or greater. Since we don't currently support the XSDT, we can't rely on that field and have to resort to the previous approach of mapping the RSDT header in order to determine the length of the RSDT itself.

Also add validation of the RSDT's checksum so we don't get tripped up by BIOS's with broken tables.

Should fix boot problems that were introduced by r42105.

24df65921b Merged signals-merge branch into trunk with the following changes:
* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
  handlers have been moved to teams. Fixes #5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO
  support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition
  of the real-time signal range. Closes #1935 and #2695.
* Gave SIGBUS a separate signal number. Fixes #6704.
* Implemented <time.h> clock and timer support, and fixed/completed alarm() and
  [set]itimer(). Closes #5682.
* Implemented support for thread cancellation. Closes #5686.
* Moved send_signal() from <signal.h> to <OS.h>. Fixes #7554.
* Lots over smaller more or less related changes.

6e70e32dec If we found a header, but it wasn't the one we were looking for, reset the header ptr to NULL after unmapping. Otherwise a bogus header pointer was potentially returned, leading to an invalid mem access. Fixes boot problems on my Athlon following recent ACPI changes.

2e8aa19c63 * The boot loader does now set up an IDT that allows it to catch processor
exceptions (page faults and the like). The handler dumps possibly interesting
  information (registers, a (numerical) stack trace) to the serial output, and,
  if possible, also to the screen. That should help debugging boot loader
  crashes.
* For the IDT the boot loader sets up for the kernel the descriptors are set up
  the same way, so until the kernel initializes the IDT itself (arch_init()) the
  facility is still in place and can thus catch very early kernel boot crashes.
  Unfortunately the on-screen output doesn't seem to work anymore at that point,
  so the output only goes to the serial port...
* ... and to the debug syslog -- dprintf() does now append it there after
  debug_cleanup() has been called. Seems to work fine in qemu, but when I tested
  it on real hardware the debug syslog was gone.

7ce4456927 * After reading the routing table(s), do another run through the PCI devices and
check if all of them are assigned with a routing entry. If not, as happens for
  PCI add-on cards that ACPI isn't aware of for example, infer the routing by
  calculating it from the PCI default routing and going up through the parents
  until a matching routing entry is found. Fixes #7520.
* This will also panic (for now) in case there remain unroutable devices and
  eventually will prevent the IO-APIC to be used in these cases.
* Enabled some debug output.

cb80e931f6 * Turn around finding the routing table on a PCI bridge and checking for it to
actually be a bridge. We always want to check if the device at hand is a PCI
  bridge, because in that case we need to recurse further down. We recurse now
  even if there is no routing table found for the current bridge, since that
  doesn't mean that another bridge, further below, can't have a routing table
  again. Possibly fixes #7520.
* Fix the matching function to just check for function 0 to be present instead
  of classifying it. Previously if there happened to be a cardbus bridge on
  function 0 of a multi function device, the rest of the functions of the device
  would've been ignored because we returned early due to the unsupported bridge.
* Only hand down the current bus number when recursing as that makes it clearer
  what's going on instead of handing in a partially filled out pci_address
  structure and then filling in other parts inside the function.
* Commented out getting the segment number as we don't support it at all.
* Extended debug output.
