4bf862e368 syslog_daemon: Converted to BServer.
* Instead of letting the kernel search for the syslog port, the
  daemon now registers itself with the kernel (which even solves
  a TODO).
* A port is created for the actual log messages from the launch_daemon,
  and used on start.
* However, the SyslogTest does not yet work, due to the BMessage <->
  KMessage communication problems.

d6d439f3f7 Reimplement unnamed POSIX semaphores using user_mutex
* Fixes sharing semantics, so non-shared semaphores in non-shared
  memory do not become shared after a fork.
* Adds two new system calls: _user_mutex_sem_acquire/release(),
  which reuse the user_mutex address-hashed wait mechanism.
* Named semaphores continue to use traditional sem_id semaphores.

b959d46dbd syscalls: Add get_stack_trace and lookup_symbol syscalls.
The get_stack_trace syscall generates a stack trace using the kernel
debugging facilities and copies the resulting return address array to
the preallocated buffer from userland. It is only possible to get a
stack trace of the current thread.

The lookup_symbol syscall can be used to look up the symbol and image
name corresponding to an address. It can be used to resolve symbols
from a stack trace generated by the get_stack_trace syscall. Only
symbols of the current team can be looked up. Note that this uses
the symbol lookup of the kernel debugger which does not support lookup
of all symbols (static functions are missing for example).

This is meant to be used in situations where more elaborate stack trace
generation, like done in the userland debugging helpers, is not possible
due to constraints.

f2f91078bd kernel/x86_64: remove memset and memcpy from commpage
There is absolutely no reason for these functions to be in commpage,
they don't do anything that involves the kernel in any way.

Additionaly, this patch rewrites memset and memcpy to C++, current
implementation is quite simple (though it may perform surprisingly
well when dealing with large buffers on cpus with ermsb). Better
versions are coming soon.

37f558d5a3 Let runtime_loader ignore RT_RELRO program headers.
* The new libstdc++.so contains program headers of type PT_RELRO (for
  making segments read-only after relocation). While the actual feature
  has not been implemented, the runtime_loader should now silently
  accept (and ignore) those program headers.

44c0c4d3d0 runtime_loader: add support for ELF based TLS
This patch introduces support of ELF based TLS handling with lazy allocation
and initalization of TLS block for each DSO and thread. The implementation
generally follows the official ABI except that generation counter in dtv
is in fact a pointer to Generation object that contains both generation
counter and size of the dtv. That simplified the implementation a bit, but
could be changed later. The ABI requirements regariding in memory position
of TLS block is not honoured what results in static TLS model being
unsupported. However, that should not be a problem as long as
"executables" in Haiku are in fact shared objects and optimizations which
require specific TLS block in memory layout are not possible anyway.

ebd3bcdb9b exfat: handle 4-byte UTF-16 surrogate pairs
... in filenames. Replace the existing Unicode conversion functions
with UTF conversion functions from js that he relicensed MIT for us.

Put the UTF conversion functions in a private but shared code location
so that they can be accessed throughout the kernel.

Right now we only provide functions to convert between UTF-8 and UTF-16.
At some point we should also add functions to convert between UTF-8 and
UTF-32 and UTF-16 and UTF-32 but these aren't needed by exfat.

Remove the old Unicode conversion functions from exfat as they assumed
UCS-2 characters and don't work with UTF-16 used by exfat.

Rename most variables with the term length with code unit where code units
are intended. The term length, when used, means length in bytes while code
units represent either a full 2-byte UTF-16 character or half a 4-byte
surrogate pair.

aa4b5749d6 runtime_loader: Detect and trigger on PE binaries
* Previously PE binaries would trigger the "incorrectly
  executable" dialog. Now we get a special message for
  B_LEGACY_EXECUTABLE and B_UNKNOWN_EXECUTABLE
* Legacy at the moment is a R3 x86 PE binary. This could
  be extended to gcc2 binaries someday far, far, down the
  road though
* The check for legacy is based on a PE flag I see
  set on every R3 binary (that isn't set on dos ones)
* Unknown is something we know *is* an executable, but
  can't do anything with (such as an MSDOS or Windows
  application)
* No performance drops as we do the PE scan last
* Tested on x86 and x86_gcc2

3a7e0b0014 packagefs: Support blacklisting entries in packages
In each installation location, it is now possible to create a settings
file "packages" that allows to blacklist entries contained in packages.
The format is:

Package <package name> {
	EntryBlacklist {
		<entry path>
		...
	}
}
...

<package name> is the base name (no version) of the respective package
(e.g. "haiku"), <entry path> is an installation location relative path
(e.g. "add-ons/Translators/FooTranslator").

Blacklisted entries will be ignored by packagefs, i.e. they won't appear
in the file system. This addresses the issue that it may be necessary to
remove a problematic file (e.g. driver, add-on, or library), which would
otherwise require editing the containing package file.

The settings file is not not "live". Changes take effect only after
reboot (respectively when remounting the concerned packagefs volume).

986e4abce4 Add new API find_path[s](), find_path_for_path()
The new functions are meant to replace many uses of find_directory():
* find_paths() is supposed to be used when the directories of a certain
  kind in all installation directories are needed (e.g. font
  directories, add-on directory, etc.). Using this API makes code
  robust wrt addition or removal of installation locations.
* find_path() is supposed to be used when files/directories associated
  with a loaded program, library, or add-on need to be found (e.g. data
  files or global settings).
* find_path_for_path() is similar to find_path(), but it starts from a
  given path instead of an image.

38fa81bf8f Remove B_COMMON*_DIRECTORY and kCommon*Directory constants
* This does intentionally break source compatibility, so that a review
  of concerned code is forced.
* Binary compatibility should be maintained in most cases. The values
  of the constants for the writable directories are now used for the
  writable system directories. The values for the non-writable
  directories are mapped to "/boot/system/data/empty/...", an empty or
  non-existent directory, so that they will simply be skipped in search
  paths. Only code that explicitly expects to find something in a
  B_COMMON_* directory, will fail.

501b24c63b ARM: kernel: Make 32/64-bit atomics work for ARMv5/6
Support for 64-bit atomic operations for ARMv7+ is currently stubbed
out in libroot, but our current targets do not use it anyway.

We now select atomics-as-syscalls automatically based on the ARM
architecture we're building for. The intent is to do away with
most of the board specifics (at the very least on the kernel side)
and just specify the lowest ARMvX version you want to build for.

This will give flexibility in being able to distribute a single
image for a wide range of devices, and building a tuned system
for one specific core type.

e85e399fd7 commpage: randomize position of commpage
This patch introduces randomization of commpage position. From now on commpage
table contains offsets from begining to of the commpage to the particular
commpage entry. Similary addresses of symbols in ELF memory image "commpage"
are just offsets from the begining of the commpage.

This patch also updates KDL so that commpage entries are recognized and shown
correctly in stack trace. An update of Debugger is yet to be done.

211f71325a x86: move x86_userspace_thread_exit() from user stack to commpage
x86_userspace_thread_exit() is a stub originally placed at the bottom of
each thread user stack that ensures any thread invokes exit_thread() upon
returning from its main higher level function.

Putting anything that is expected to be executed on a stack causes problems
when implementing data execution prevention. Code of x86_userspace_thread_exit()
is now moved to commpage which seems to be much more appropriate place for it.

3b4269ecf5 arch: randomize initial user stack pointer
Inside the page randomization of initial user stack pointer is not only a part
of ASLR implementation but also a performance improvement that helps
eliminating aligned 64 kB data access.

Minimal user stack size is increased to 8 kB in order to ensure that regardless
of initial stack pointer value there is still enough space on stack.

Alex Smith
8a1903353e Implemented user debugging support for x86_64.
Reused x86 arch_user_debugger.cpp, with a few minor changes to make
the code work for both 32 and 64 bit. Something isn't quite working
right, if a breakpoint is hit the kernel will hang. Other than that
everything appears to work correctly.

Alex Smith
6e2f6d1ace Changed cookie type for get_next_area_info() to ssize_t.
The cookie is used to store the base address of the area that was just
visited. On 64-bit systems, int32 is not sufficient. Therefore, changed
to ssize_t which retains compatibility on x86 while expanding to a
sufficient size on x86_64.

Alex Smith
59ae45c1ab Fixed commpage for x86_64.
Since the commpage is at a kernel address, changed 64-bit paging code
to match x86's behaviour of allowing user-accessible mappings to be
created in the kernel portion of the address space. This is also
required by some drivers.

195a0f350e Changed argument type of fcntl syscall from uint32 to size_t.
Since this argument may be used to pass pointers, uint32 is not
correct for 64-bit. Effectively no change on 32-bit targets, both
size_t and uint32 are unsigned long there.

Alex Smith
3b802628b8 Support ELF64 in the kernel.
This has been done by adding typedefs in elf_common.h to the correct ELF
structures for the architecture, and changing all Elf32_* uses to those
types. I don't know whether image loading works as I cannot test it yet,
there may be some 64-bit safety issues around. However, symbol lookup for
the kernel is working correctly.
2012-07-09 11:11:38 +01:00
Alex Smith
ccadfaeeb5 Changed the boot ELF code to use templates and added ELF64 support.
The actual implementation of the ELF loading methods have been put into
an ELFLoader template class that takes a single template parameter, which
is a structure containing all the necessary ELF typedefs. It's a bit
verbose, but I thought it was a neater solution than using a bunch of
standalone functions with a huge number of template parameters. There is
no change to code outside of elf.cpp, the ELF32/ELF64 differences are
handled internally.

65ad1ba320 Made it possible to build the bootloader when targetting x86_64.
* x86_64 is using the existing *_ia32 boot platforms.
* Special flags are required when compiling the loader to get GCC to compile
  32-bit code. This adds a new set of rules for compiling boot code rather
  than using the kernel rules, which compile using the necessary flags.
* Some x86_64 private headers have been stubbed by #include'ing the x86
  versions. These will be replaced later.

* 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.

af2da315dc Fix the larger problem that was hiding behind the build problem of set_haiku_revsion on FreeBSD:
* the length of the sHaikuRevision character array symbol needs to be set explicitly,
  as using either _SYS_NAMELEN or sizeof(utsname::version) will only return the values
  for the host, which may not match ours, thus potentially causing problems when using
  sHaikuRevision
* add headers/private/system_revision.h which defines SYSTEM_REVISION_LENGTH to 128
* adjust definitions of sHaikuRevision in libroot and kernel accordingly
utsname::version is shorter than SYSTEM_REVISION_LENGTH, but that doesn't cause any harm
until we have indeed switched to a DVCS (in which case longer revision strings will be 
cut off by 'uname').

56b5ad0781 Added a temporary opt-in option "enable_ioapic" to the boot menu. This way the
IO-APIC can be easily enabled to test it on various configurations. Note that
the previous default opt-out didn't work because the safemode options would not
be touched at all when not actually entering the boot menu.
Once IO-APIC is more broadly tested this can be removed again and the opt-out
option reenabled.

7e965f506d More consolidation of timezone code:
* dropped DaylightSavingTime from real_time_clock code in kernel, it was
  never really being used for what it meant (and just being referred to by
  gettimeofday(), which put a different meaning to it
* adjusted the syscalls get_timezone() & set_timezone() as well as their callers 
  accordingly
* got rid of get_rtc_info() and rtc_info struct in kernel, as it was only
  being referred to by the FAT add-on and that one (like gettimeofday()) put a
  different meaning to tz_minuteswest. Added a comment to FAT's util.c
  showing a possible solution, should the hardcoded GMT timezone pose a problem.
* fixed declaration of gettimeofday() to match POSIX base specs, issue 7
* changed implementation of gettimeofday() to not bother trying to fill struct
  timezone - it was using wrong values before, anyway.

  relevant (and the two corresponding parameters were removed)
* C++-ified and reworked clockconfig to use the info from 'Time settings' 
  to setup the timezone info during boot
* removed invocation of _kern_get_tzfilename() from tzset(), as the syscall
  no longer exists and tzset() is currently broken anyway
* adjusted the Time preflet to use the renamed syscall when getting/setting 
  the RTC info

locks.
* Added syscalls for a new kind of mutex. A mutex consists only of an int32 and
  doesn't require any kernel resources. So it's initialization cannot fail
  (it consists only of setting the mutex value to 0). An uncontended lock or
  unlock operation can basically consist of an atomic_*() in userland. The
  syscalls (when the mutex is contended) are a bit more expensive than semaphore
  operations, though.
