Marcus Overhagen 93d0c77a96 added debugging code, can be disabled, currently enabled

Ingo Weinhold 571bb2b2a6 Simplified the x86 syscall interface a bit. We no longer pass a pointer
to the parameters nor the number of parameters; the kernel is able to
get both without problems.

The syscall functions in libroot (_kern_*()) are now self-contained
(they don't "jmp" to separate code anymore), which at least
theoretically allows gdb to print a stack trace with the syscall
function on the top when a thread is currently performing a syscall.
Practically it doesn't work yet, though, since those functions are
frameless (i.e. create no stack frame) which needs special support
I haven't implemented yet.

Ingo Weinhold 37a25a6ceb * Fail, if debug_thread() is invoked for the debug nub thread.
* To always be on the safe side, thread_hit_debug_event() now checks
  whether the thread is the debug nub thread.

Axel Dörfler 06be24a748 The spurious debug exception sometimes comes very often in QEMU - it's now only
printed when tracing is turned on.

No longer uses dprintf() in the kernel debugger.

Axel Dörfler 05a7818c85 Removed the "list all team" functionality from the debugger command "team", and
moved it into the new command "teams". Now also lists the parent team.

Axel Dörfler dcdebb933e The debugger command "threads" now accepts an argument that let's you filter the
threads listed by team ID. Also, the thread's team is now printed in the list as
well.
Minor cleanup (renamed "t" to "thread" where appropriate).

Axel Dörfler 0e1358bd5c Applied a patch from Alexander Deynichenko: added missing signal definitions.
That also includes some XSI signals, SIGPOLL and SIGVTALRM, dunno if we will every support
those in a useful way.

Axel Dörfler 8fcd6b8e61 * renamed smp_boot.c to smp.cpp
* there is now a "Disable Hyper-Threading" safemode in the boot loader
* the SMP & HT menu items are now added in smp.cpp - and are only added
  if the system supports one of them.
* more cleanup to smp_apic.h
* removed cpuid() from the boot loader's support.S - instead, it will now
  use the one from the kernel.
* added a very weak HT detection: if the MP config only listed one CPU,
  and this CPU supports HT, we enable the other logic processor manually -
  as this currently doesn't work, it's disabled, though.

Axel Dörfler ef7bac18bb Implemented call_all_cpus(), and get_cpuid() properly (tested only the latter, though).
The "data_ptr" parameter is now only freed if you specify SMP_MSG_FLAG_FREE_ARG
when sending the ICI message.

Axel Dörfler 50374cbdca Changed the signal handling code so that handle_signals() can be called without
having the thread lock held and interrupts disabled.
Cleaned up the signal handling code, and fixed some minor bugs with blockable
vs. non-blockable signals.
thread_debug_info was using uint64 for signals sets instead of sigset_t.

Axel Dörfler 7121425eb5 Turns out we could remove a mount point...
Under BeOS remove_vnode() is failing in this case, which looks like a good idea to imitate.
Also, pipefs/rootfs didn't handle that case - they even removed the entry before calling
remove_vnode() - they now behave correctly. And also BFS now returns the actual error code
received from remove_vnode() instead of B_ERROR.

Axel Dörfler 1c88c851ad Turned off debug output again - also temporarily removed the file cache warning
about our block_io module not honouring the total length in read_pages().
Removed drops into the debugger when there is a block without an "original"
data buffer - that's completely normal and happens when someone asks for
a cleared block that is not yet in the cache.

Axel Dörfler 0fc0129604 Fixed another stupid bug in all readv()/writev() versions: the position of
the read/write access was only correct for the first entry in the iovec.
These functions should be updated to use read_pages()/write_pages() where
possible, anyway - right now, they only save some kernel calls, while they
could be processed by the device at once.

Axel Dörfler 28953e6c2b Fixed two stupid bugs in _kern_writev() and _kern_readv() - they accidently
tried to write from/read to the userland file descriptor instead of the one
of the kernel.

Axel Dörfler 3ea780cdf9 If booted from an image, the list of possible boot partitions is now ordered by
some heuristic: when you booted from a CD, CDs are preferred; else, volumes with
names like "Haiku" or "System" are preferred - if someone has better ideas, please
shout.
Note, this heuristic will only come into play if the boot loader was loaded from
an image (ie. floppy/CD/network), and you didn't choose any boot device.
Added evil methods to the Stack class that come in handy (you can now directly
access the array) for this.

Axel Dörfler 2db3fced5f Moved vfs_bootstrap_file_systems() and vfs_mount_boot_file_system() out of vfs.cpp
and into its own file vfs_boot.cpp.

Added basic support for booting from CD - it doesn't give CDs a higher priority,
so you could end up booting from HD when you didn't explicetly select "CD-ROM"
in the boot loader. Eventually, it should only boot from HD in this case, if
booting from CD failed (because of a missing boot partition or whatever).

fs_mount(), _kern_mount(), and _user_mount() will now return the dev_t of the
mounted device, and not just B_OK. Maybe we should have fs_unmount() work on
a dev_t instead of a path as well...

Axel Dörfler 681779f1c8 Our close-on-exec flag handling was broken: it's supposed to be specified per slot, not
per file descriptor (a descriptor can be shared among several slots). There is now a
second table in the io_context structure that contains that information in a bitmap.
There are now two new (private) functions to control the close-on-exec flag, fd_close_on_exec(),
and fd_set_close_on_exec().
F_DUPFD, dup(), and dup2() are supposed to clear the close-on-exec flag on the duplicated
slot - this fixes bug #57 (no output after a redirect of a shell builtin).

Axel Dörfler 9e3ebf4033 exit_thread() no longer sends a signal when it's called from a kernel thread - instead,
it will exit directly to have the same behaviour as in user space (where it doesn't

Axel Dörfler 08da6fccdd Introduced a sane concept of ownership for the team_args structure: now load_image_etc()
and exec_team() have an additional "kernel" argument and will copy the arguments
themselves (or rather, delegate that to create_team_arg()).
When team_create_thread_start() is called, it will take over ownership and is
responsible for deleting it - this also fixed a memory leak in case the user
stack area couldn't be created.
Also changed comment after exit_thread(): since this call only delivers a signal, the
code after it will still get executed.
This fixes the crashing symptom of bug #50.

Axel Dörfler f10cba9aec Changed get_mount() to return a status code instead of just the mount or NULL.
Some fields of fs_mount were not properly initialized when FS's mount function
was called, and therefore, could let get_mount() return a mount structure that
was not yet read for public consumption (this should fix bug #51).
