0f4242de40 Implement a vm_block_address_range() function which creates an area with no
mapped pages and a non-read and non-write protection to block a certain address
range from being used by anything.

fbcf5f3f92 Don't know what this was supposed to do, but with the VADDR_TO_PDENT() it would
end up as 0 again in any case. It certainly looks correct without it, removing
so it doesn't confuse the next one reading over it.

257f000bd2 * When reserving pages and there aren't yet enough free pages, only steal as
many pages as are actually missing, not the full count.
* Take into account that free_page_queue_count() can be less than sReservedPages
  (when some of the reserved pages have been allocated already) in
  vm_page_num_unused_pages(). Before it could return negative and therefore
  wrapped numbers.
* Simplify the page scrubber loop by continuing early. Also avoids a needless
  interrupt spin lock acquisition when there's nothing to do.
* Some minor coding style cleanup.
* Fix a typo.

b2350565ba Fix two problems in devfs_io:
* An off by one error prevented the very last block of a device to be accessed
  through IO.
* In case of error the request wasn't notified causing anyone (the page writer
  for example) to wait forever for the request to complete.

185fd1c5d2 Ported over the kernel heap to libroot to make use of it's validation
capabilities to aid in debugging memory corruption issues.

It does:
* Initialize memory to 0xcc to help turn up use of uninitialized memory
* Set freed memory to 0xdeadbeef to help find accesses of freed memory
* Use the paranoid heap validation to turn up many cases of memory corruption
* Use a simplistic wall check to turn up memory overwrites past allocations
* Take extra steps to validate freed addresses to turn up misaligned frees

It has an interface to en-/disable paranoid validation and to start/stop regular
wall checking. Both are currently just enabled. At a later stage a debug version
of libroot could be used by an application and the checks enabled at will. Note
that due to the paranoid validation and the suboptimal locking this allocator
will perform horribly. Still to find memory corruption issues in the system or
also in your applications it can be helpful to build your installation with it
turned on. To enable it you currently need to edit the Jamfile to sub-include
the malloc_debug instead of the malloc directory.

419f2d6f3e Fix errors in maintaining the area list due to assumptions that are only true
for the page list but not the area one. Since multiple pages can be allocated
at once, even an area that is not at the top of the list can become empty. In
such a case the area list would previously have lost entries. Also because
we can remove more than one page from any area, not just the top one, we may
need to move forward in the list so that it stays ordered by free pages.

92e143c14a Fix regression introduced in r32526: registering the device watcher for node monitoring needs to happen synchronously, otherwise a race condition occurs: unless you're very lucky, the event for creating the raw device would happen before the async thread had a change to add the node monitor, and as such the listener would miss it, and never trigger a filesystem/partition scan. As a result, whether or not adding a USB stick would actually show a volume was essentially russian roulette. Fixes ticket #4345.

adbf8b25f8 * Added fdopendir() (POSIX).
* Got rid of <dirent_private.h> -- the __DIR structure is private to dirent.c,
  now. The attribute directory, index directory, and query functions use the
  the public POSIX API, so does the kernel module code. Those components were
  not initializing the structure correctly anymore since the introduction of
  telldir()/seekdir().

8c5ad61d4b * Prevent the /boot entry from ever being renamed. You couldn't even try to
switch /boot to a different volume in two operations, unless you have first
  linked /system/lib into /bin. This patch assumes that / will always have the
  ID 1. Don't know if that is proper. Note that I also thought about solving
  this in the VFS, since perhaps it isn't the job of root-fs to know about
  /boot, but that would of course introduce another check for every rename
  operation, which I decided against.

89294b5084 * Added option for enabling serial debug output.
* Moved device_manager/settings.cpp to debug/safemode_settings.cpp.
* Removed the somewhat hacky concatenation of kernel settings and safemode
  settings in the boot loader. Instead, get_safemode_option() will now fall
  back to the kernel settings, if it couldn't spot a setting in the safemode
  settings. This allows for more control, and also makes enabling serial
  debug output actually work (ie. overriding the kernel settings via safemode
  options).
* Adjusted debug_init_post_vm(), and smp_init_other_cpus() to use
  get_safemode_boolean().
* Therefore, I added safemode_settings.cpp to the boot loader as well.

* Keep track of the currently running threads.
* Make use of that info to decide if a thread that becomes ready should preempt
  the running thread.
* If we should preempt we send the target CPU a reschedule message.
* This preemption strategy makes keeping track of idle CPUs by means of a bitmap
  superflous and it is therefore removed.
* Right now only other CPUs are preempted though, not the current one.
* Add missing initialization of the quantum tracking code.
* Do not extend the quantum of the idle thread based quantum tracking as we want
  it to not run longer than necessary. Once the preemption works completely
  adding a quantum timer for the idle thread will become unnecessary though.
* Fix thread stealing code, it did missed the last thread in the run queue.
* When stealing, try to steal the highest priority thread that is currently
  waiting by taking priorities into account when finding the target run queue.
* Simplify stealing code a bit as well.
* Minor cleanups.

73c035dc11 * Set freed memory to 0xdeadbeef before returning it to page. This allows us to
not hold the bin lock while setting and only protect the actual freeing. May
  reduce bin lock contention a little bit.
* Tiny optimization for force-clearing 0xdeadbeef. Do it after setting to 0xcc,
  so that it's less likely we have to do it.

4e4ff20294 common_poll():
* Always select POLLNVAL. We wouldn't get notified, if the FD was closed while
  waiting.
* Skip negative FDs (as per POSIX standard).
* When encountering an invalid FD, we must not wait. Previously we did that as
  long as any FD was valid.
* The return count must consider all FDs with non-null revents, including
  invalid ones (revents is POLLNVAL then).

common_poll()/common_wait_for_objects():
* Don't bail out early, when no FDs/objects have been selected. We always want
  to wait.

_user_poll()/_user_wait_for_objects():
* Copy the array back to userland even if common_*() returned an error. The
  functions do now always fill in the resulting events.

57dc0e2a53 Changed the FD selection/deselection handling a bit:
* B_EVENT_INVALID is no longer passed to the FD's select()/deselect() hooks.
* Now we always attach the select info to the I/O context, even if no event has
  been selected. The reasoning is that B_EVENT_INVALID is always automatically
  selected and handled by the VFS, so we need the handle to notify on close().

bb693d7764 * Added VESA capabilities field to the kernel args.
* The vesa driver no longer uses VGA programming if the chip does not support
  VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
  the new vesa_set_indexed_colors() that is now used for palette programming.
  This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
  hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
  right now, the colors are garbled after a workspace switch. Stefano, are you
  looking into that already?

	- add various addresses, boot script, custom C/C++ flags and SD card definition,
	- not sure BoardSetup is included at the best place though,
	- replaced board-specific ldscript with passing the loader address directly to LD from BoardSetup,
- added haiku.mmc target which generates an mmc/SD card image with a FAT partition with the files needed to boot for the board, should later be integrated with haiku.image with the BFS partition offset passed to bfs_shell, requires apt:sfdisk,mtools on GNU/Linux,
- added some more rules, one to build a script for the SD image,
- fake a NetBSD loader for now, U-Boot doesn't know haiku, and we'll need a way to pass the tgz image and RAM size, we'll either use standlone way (usual C argv[]) or the NetBSD args,
- style fixes,
- 80 cols, /me pets Ingo.

50d22f83ef The reference of the currently active translation map shouldn't be released
until the data it protects isn't in active use anymore. Previously it would
release the translation map and therefore the page directory reference while
the page dir was still set on the CPU, as only the actual call to
i386_context_switch() will replace the page directory in the control register.
This didn't cause any harm though, as during the context switch interrupts are
disabled and therefore the page directory would only be deferred_delete()ed and
not directly freed/overwritten. Still this is logically more correct.

ee280b59e9 Prevent the user TLB invalidation function from being preempted by turning off
interrupts when invoking it. The user TLB invalidation function essentially only
reads and writes back control register 3 (cr3) which holds the physical address
of the current page directory. Still a preemption between the read and the write
can cause problems when the last thread of a team dies and therefore the team
is deleted. The context switch on preemption would decrement the refcount of the
object that holds the page directory. Then the team address space is deleted
causing the context switch returning to that thread to not re-acquire a
reference to the object. At that point the page directory as set in cr3 is the
one of the previously run thread (which is fine, as all share the kernel space
mappings we need). Now when the preempted thread continues though, it would
overwrite cr3 with the physical page directory address from before the context
switch still stored in eax, therefore setting the page directory to the one of
the dying thread that now doesn't have the corresponding reference. Further
progressing the thread would release the last reference causing the deletion
of the object and freeing of the, now active again, page directory. The memory
getting overwritten (by deadbeef) now completely corrupts the page directory
causing basically any memory access to fault, in the end resulting in a
triplefault. This should fix bug #3399.

56c6c0fefb - introduced an "argumetns" field in stage2_args to hold command line args from chaining loader,
- added some multiboot support code:
	- dump some of the passed info,
	- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)

255c9104e5 * Rework the heap locking strategy. Use a read-write lock for the area lock to
allow for more parallelism. Also introduce seperate locks for the bins and
  for page allocation. This greatly reduces lock contention and reduces the
  duration the locks are held due to them overall protecting less code. Now only
  allocations of the same size hitting the same allocator or allocating larger
  chunks of memory should block. Previously, basically any allocation and also
  free would be mutually exclusive, making it scale pretty badely.
* Added memalign_nogrow(). As it uses heap_memalign() anyway, there's no real
  reason not to allow for an alignment.
* Some cleanup.

ea2abd110b * Renamed the ROUNDOWN macro to ROUNDDOWN. Also changed the implementation of
ROUNDUP to use '*' and '/' -- the compiler will optimize that for powers of
  two anyway and this implementation works for other numbers as well.
* The thread::fault_handler use in C[++] code was broken with gcc 4. At least
  when other functions were invoked. Trying to trick the compiler wasn't a
  particularly good idea anyway, since the next compiler version could break
  the trick again. So the general policy is to use the fault handlers only in
  assembly code where we have full control. Changed that for x86 (save for the
  vm86 mode, which has a similar mechanism), but not for the other
  architectures.
* Introduced fault_handler, fault_handler_stack_pointer, and fault_jump_buffer
  fields in the cpu_ent structure, which must be used instead of
  thread::fault_handler in the kernel debugger. Consequently user_memcpy() must
  not be used in the kernel debugger either. Introduced a debug_memcpy()
  instead.
* Introduced debug_call_with_fault_handler() function which calls a function
  in a setjmp() and fault handler context. The architecture specific backend
  arch_debug_call_with_fault_handler() has only been implemented for x86 yet.
* Introduced debug_is_kernel_memory_accessible() for use in the kernel
  debugger. It determines whether a range of memory can be accessed in the
  way specified. The architecture specific back end
  arch_vm_translation_map_is_kernel_page_accessible() has only been implemented
  for x86 yet.
* Added arch_debug_unset_current_thread() (only implemented for x86) to unset
  the current thread pointer in the kernel debugger. When entering the kernel
  debugger we do some basic sanity checks of the currently set thread structure
  and unset it, if they fail. This allows certain commands (most importantly
  the stack trace command) to avoid accessing the thread structure.
* x86: When handling a double fault, we do now install a special handler for
  page faults. This allows us to gracefully catch faulting commands, even if
  e.g. the thread structure is toast.

We are now in much better shape to deal with double faults. Hopefully avoiding
the triple faults that some people have been experiencing on their hardware
and ideally even allowing to use the kernel debugger normally.

Based on a patch from Dustin Howett, reworked, and help from Vladimir 'phcoder' Serbinenko.
- used defines for clarity, the rest of teh code could make use of them too...
- added a gMultiBootInfo pointer to the passed args, to let C code handle it instead of faking the boot drive ID,
- conditionalized the copy back, maybe we can get rid of it when QEMU handles our default load address correctly,
- added video mode info to ask for 1024x768 but QEMU ignores it anyway, and we might need to show the menu, so it's disabled.

671a2442d9 More work towards making our double fault handler less triple fault prone:
* SMP:
  - Added smp_send_broadcast_ici_interrupts_disabled(), which is basically
    equivalent to smp_send_broadcast_ici(), but is only called with interrupts
    disabled and gets the CPU index, so it doesn't have to use
    smp_get_current_cpu() (which dereferences the current thread).
  - Added cpu index parameter to smp_intercpu_int_handler().
* x86:
  - arch_int.c -> arch_int.cpp
  - Set up an IDT per CPU. We were using a single IDT for all CPUs, but that
    can't work, since we need different tasks for the double fault interrupt
    vector.
  - Set the per CPU double fault task gates correctly.
  - Renamed set_intr_gate() to set_interrupt_gate and set_system_gate() to
    set_trap_gate() and documented them a bit.
  - Renamed double_fault_exception() x86_double_fault_exception() and fixed
    it not to use smp_get_current_cpu(). Instead we have the new
    x86_double_fault_get_cpu() that deducts the CPU index from the used stack.
  - Fixed the double_fault interrupt handler: It no longer calls int_bottom to
    avoid accessing the current thread.
* debug.cpp:
  - Introduced explicit debug_double_fault() to enter the kernel debugger from
    a double fault handler.
  - Avoid using smp_get_current_cpu().
  - Don't use kprintf() before sDebuggerOnCPU is set. Otherwise
    acquire_spinlock() is invoked by arch_debug_serial_puts().

Things look a bit better when the current thread pointer is broken -- we run
into kernel_debugger_loop() and successfully print the "Welcome to KDL"
message -- but we still dereference the thread pointer afterwards, so that we
don't get a usable kernel debugger yet.

cc77aba101 * Allocate a separate double fault stack for each CPU.
* Added x86_double_fault_get_cpu(), a save way to get the CPU index when in

  intact thread structure, so we rather want to avoid it when handling a double
  fault. There are a lot more of those dependencies in the KDL entry code.
  Working on it...

c32499b4f7 * Since the file_map reports its chunk with a file system specific alignment, we
cannot assume that the file is that long - we need to check for the actual
  file size specifically, and then clear the extraneous bytes based on that one.
* This fixes seeing old file left-overs in the space beyond the file size in
  mmapped file. Thanks to Oliver who provided me with a nice test program to
  reproduce this problem (this should also fix gcc's fix_includes app (although
  I wonder what it does if a file actually ends on a page boundary).
* Also fixed a bug in precaching that would cause the last page of the cache
  to be discarded, causing it to be re-read later on.
* Moved partial page clearing into its own function
  read_pages_and_clear_partial(), even though it's currently only used once.

d829579dc0 mmlr + bonefish:
Moved the static variables for managing the tracing buffer into a separate
area. The area is mapped at one of a few possible physical addresses and can
be found again when rebooting. This allows us to resurrect the tracing buffer
from the previous session, which could help tremendously when tracking certain
bugs (like triple faults). There's very little checking done yet, so it is
probably not as robust as we would wish it to be.

  isn't left to the debugger.
* Removed the _kern_get_thread_cpu_state() syscall. Was originally intended for
  bdb compatiblity, but isn't really needed.
* Kernel x86 arch_get_debug_cpu_state(): The use of fnsave was broken, since
  it reinits the FPU after saving the state. This resulted in weird results
  when debugging functions using the FPU. We now use fxsave, if available.

patch from about a year ago (I couldn't use any code of his yet, though,

  pressing Alt-SysReq + key.
* By default, only Alt-SysReq+'d' is used as a means to deliberately enter
  the kernel debugger. F12 belongs to userland again, now :-)
* Debugger add-ons now have another optional method to implement their own
  emergency keys - 'd' for the debugger cannot be overridden, though.
* The mechanism can be turned off via a new kernel setting, so it's not that
  easy anymore to "crash" Haiku if you don't want to.

  keyboard mini-driver support this, USB not yet.

24a9c1bbba * Added option "-r, --recorded" to profile: this will now retrieve the kernel
profile data area, and evaluate its data - it doesn't produce any output yet,
  though.
* _user_system_profiler_recorded() now also makes sure the userland app can read
  from the buffer area.
* Fixed leak in SharedImage::Init().
* Made the symbol retriever more smart when it deals with kernel images; if the
  image ID is no longer available, it will now use the path based image symbol
  iterator (and also adds the boot kernel path, in case the module don't have
  one).

a365e1cfbb Patch by Bryce Groff, some changes by myself:
* devfs:
  - devfs_[un]publish_partition(): They no longer get the partition path as
    parameter, but rather the device path and the partition name.
  - Added devfs_rename_partition(), which renames an already published
    partition node.
* KPartition/KDiskDevice:
  - Replaced the fPublished flag by fPublishedName, the name under which the
    partition is published. This simplifies UnpublishDevice() and makes it
    practically infallible.
  - Added GetFileName(), which only returns the partition's file name.
    Simplified GetPath() by using it.
  - When a partition is added/removed the subsequent sibling partitions get a
    new index. Now we also rename their published device nodes (and those of
    their descendents). When something goes wrong we unpublish the concerned
    partition's device to be on the safe side. Would be a shame to accidentally
    format the wrong partition, eh? :-)

be1f4fe800 * find_symbol_breadth_first() didn't ever set _foundInImage, although
it's signature indicates that it should - the callers just never use
  the value currently, so it caused no harm
* squashed a TODO in the runtime_loader about the resolving strategy
  for undefined symbols in add-ons: I've implemented the breadth-first
  strategy (leaving out the add-on itself), as that one made most sense to
  me.
This avoids loader problems with older optional packages of Pe on gcc4, as some
add-ons (e.g. "Expand Tabs") could not be loaded due to them containing undefined
symbols that are found in second level dependencies (libstdc++.so in this case).

Ingo: please review.

181593ba0b * Properly document why fs_write_attr() does what it does.
* As even the author of fs_attr.c was trying to use fs_write_attr() in an
  unsupported way in the cp copy_attributes() implementation, try to be
  more forgiving and support writing attributes at an offset. The method is
  required to behave inconsistent in that replacing bytes at offset 0 is
  not supported as replacing bytes at any other offset. Writing at offset 0
  will clobber the existing attribute to stay compatible with BeOS.

NOTE: BFS itself still does not support writing attributes at an offset which
are withing the "small data section". To work around this problem, programs
which copy attributes in a loop must make sure that their buffer is large
enough that such "small data section" attributes require only one loop
iteration.

e0965f2727 * reload_driver() now also checks if the binary node changed, and will update
the node listener, to make sure it won't lose track.
* The DriverWatcher now also listens for B_ENTRY_REMOVED. This causes drivers to
  be unpublished even if they are only symlinked.
* However, to detect new drivers in a symlinked location, we'd need special
  support for those, and also need to watch the parent directory of the symlink
  target - this is close to overkill, so I stayed away from implementing that
  for now :-)

  before, but there shouldn't be a problem, if the thread has to wait.

568ade58d0 User debugger support:
* Generalized address checks. The debugger can now also read the commpage.
* Added new syscall _kern_get_thread_cpu_state() to get the CPU state of a
  not running thread. Introduced arch_get_thread_debug_cpu_state() for that
  purpose, which is only implemented for x86 ATM (uses the new
  i386_get_thread_user_iframe()).
* Don't allow a debugger to change a thread's "esp" anymore. That's the esp
  register in the kernel. "user_esp" can still be changed.
* Generally set RF (resume flag) in eflags in interrupt handlers, not only
  after a instruction breakpoint debug exception. This should prevent
  breakpoints from being triggered more than once (e.g. when the breakpoint is
  on an instruction that can cause a page fault). I still saw those with bdb
  in VMware, but that might be a VMware bug.

f835a75f31 Make two runs of MTRR setting when setting memory ranges to write-back. At the
first run only set up uncacheable MTRRs and in the second run set the write-back
ones up. If this order is not followed, we could set too large ranges to
cacheable first and then limit it back to uncacheable later. On systems with
enough physical memory this would lead to a temporary situation in which areas
become cacheable that must not be, resulting in system hangs or other unexpected
behaviour. Fixes last part of #4018.

360d4974b9 Replaced the temporary storage used in the kernel debug command parser. We now
have a simple dedicated heap for the kernel debugger with stacked allocation
pools (deleting a pool frees all memory allocated in it). The heap should
eventually be used for all commands that need temporary storage too large for
the stack instead of each using its own static buffer.
