Currently there are two generators. The fast one is the same one the scheduler
is using. The standard one is the same algorithm libroot's rand() uses. Should
there be a need for more cryptographically PRNG MD4 or MD5 might be a good
candidates.
Placing commpage and team user data somewhere at the top of the user accessible
virtual address space prevents these areas from conflicting with elf images
that require to be mapped at exact address (in most cases: runtime_loader).
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.
Set execute disable bit for any page that belongs to area with neither
B_EXECUTE_AREA nor B_KERNEL_EXECUTE_AREA set.
In order to take advanage of NX bit in 32 bit protected mode PAE must be
enabled. Thus, from now on it is also enabled when the CPU supports NX bit.
vm_page_fault() takes additional argument which indicates whether page fault
was caused by an illegal instruction fetch.
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.
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.
* If we have a configured network, then we always try to connect to it
as soon as the interface has been brought up.
* If we don't have a configured network and are auto configuring, we
use the AutoconfigLooper to also do initial auto joins.
* Before issuing auto joins we need to wait for scan results to come
in, so we watch for corresponding messages.
For now auto joining is a one shot attempt as the infrastructure to
properly tell reasons for scans apart is not yet there.
The physical memory map area was not included in the kernel virtual
address space range (it was below KERNEL_BASE). This caused problems
if an I/O operation took place on physical memory mapped there (the
bad address error seen in #9547 was occurring in lock_memory_etc()).
Changed KERNEL_BASE and KERNEL_SIZE to cover the area and add a null
area that covers all of it. Also changed X86VMTranslationMap64Bit to
handle large pages in Query(), as the physical map area uses large
pages.
* This parses the reported CPU name, and tries to translate it to a normal
and concise identifier.
* For example, it will translate "AMD FX(tm)-8320 Eight-core Processor" into
"FX™ 8320" or "Dual Core AMD Opteron(tm) Processor 275 HE" into
"Opteron™ 275 HE".
* This means we can remove AMD strings for those models for which this
function produces useful results.
* Replace {Set|Remove}MasterKey() by generic {Set|Remove}UnlockKey()
that works on a keyring.
* Implement {Set|Remove}MasterUnlockKey() on top of that.
* Rename the commands and constants accrodingly.
* Implement setting and removing keyring unlock keys.
* The keystore backend will (at least for the time being) reside in a
separate server. This one can be reached via normal messaging, so use
a BMessenger for sending key messages.
* Move the message constants from RegistrarDefs.h into a new
KeyStoreDefs.h that also contains the server signature.
* Update the message constants to reflect the new situation.
* Add all relevant message constants.
* Implement the messaging to send/retrieve key info.
* Implement _Flatten/_Unflatten for sending flat BKey objects.
* Remove application list from BKey, the key can't only differ by
allowed applications as the identifiers would still collide, so the
comparison isn't needed to uniquely identify the key. The applications
can be enumerated via the BKeyStore instead.
* The user of an editor needed knowledge about the editor in order to make
use of it.
* Furthermore, the BPartitionParameterEditor exposed type specific
functionality that it shouldn't know anything about, either.
* We may now define a number of known parameters per editor type; right now
there is only "type" as it's needed by DriveSetup.
* Adapted all disk systems, and DriveSetup to the new API.
* Renamed CreateParamsPanel, and InitializeParamsPanel to *ParametersPanel
in DriveSetup.
* They now share a common base class AbstractParametersPanel.
* edid1_detailed_timing_raw was missing
a field which threw off the sync bits.
* The result was the monitor will receive
a different sync polarity than it requested.
Most monitors handle this, but it is still
a bug
* Added the aforementioned functions.
* create_area_etc() now takes a guard size parameter.
* The thread_info::stack_base/end range now refers to the usable range
only.
* use only a single static object (MutableLocaleRoster) instead of
two, which avoids any problems if the order of static object
destruction would destroy RosterData before MutableLocaleRoster
* rename BPrivate::RosterData to BPrivate::LocaleRosterData and move
it into a header and implementation file of its own
This should hopefully fix problems encountered with a clang-compiled
Locale Kit.
Since we're using multi-part uImage format, we can add the FDT as
a seperate "blob" in the uImage, if the used U-Boot version is not
"FDT enabled".
This is used for example for our Verdex target. Currently I've got
a local hack in the platform/u-boot/Jamfile, looking into pulling
in the FDT files and a proper Jam setup to do that properly...
This detects everything up to ARMv6 right now. Need to check more
recent ARM ARMs for ARMv7 detection.
The detected details get passed on to the kernel, which can use
the pre-detected info for selecting right pagetable format and such.
Copyright removal of Axel done after agreement with Axel @ BeGeistert
that for files that were copy/pasted from x86 arch and then fully
replaced the implementation, removal of original copyright holder is
allowed, since their actual code is gone ;)
Pass the BHandler object that opened the about window to BAboutWindow.
When the window closes, send a kAboutWindowClosed message back to the
handler. This allows the handler to set the variable to NULL.
Implement the new about dialog constructor in all apps that use it.
Remove the old constructor. This now works reliably for all cases I
tested without crashing and does the right thing on close. The setup
and teardown is a bit more complicated than I wanted though.
Unfortunately this seems to be necessary when not using a BAlert.
Fetching the app icon does not work reliably yet. This is because for
replicants the app may not be running. I may have to pass the icon in
instead of grabbing it from the signature.
* Grabs the app icon and version from the resource file.
* Allow you to specify the copyright holder instead of hardcoding
"Haiku, Inc."
* Support multiple extra copyright fields.
* Modify BAlert to take a custom icon.
* Set the custom icon of the BAlert to the app icon.
* Also set the app version.
* Convert BAboutWindow to derive from BWindow
* Place a 128x128 icon and fill out a scrolling BTextView
with options such as authors, version history, copyright,
license, etc. Still needs some work but is coming along.
* Add the word Version to the version line, i8n'ed of course,
and tweak the info box and default sizes.
