* VMAddressSpace: Add randomizingEnabled property.
* VMUserAddressSpace: Randomize addresses only when randomizingEnabled
property is set.
* create_team_arg(): Check, if the team's environment contains
"DISABLE_ASLR=1". Set the team's address space property
randomizingEnabled accordingly in load_image_internal() and
exec_team().
If for some reason (e.g., a forced rebuild), Buildbot rebuilds the same hrev,
it was possible for the scp command to place the repositoryDir as a subdir
in $arch/$version/, instead of as $arch/version. This should ensure that the
contents of repositoryDir are placed in $arch/$version/.
In that case the caller ideally wants to obtain an allocation at the
specified address, which was thwarted by using
B_RANDOMIZED_BASE_ADDRESS. Use B_BASE_ADDRESS instead.
This improves the experience with the gcc 4 pre-compiled headers
implementation (which expects to be able to map the PCH file at the same
address where it was located originally when it had been created), but
doesn't fix it completely. As long as ASLR is active, it is always
possible that something else (mapped shared objects, heap, stack) is in
the way.
Unless a free range was found before the first area a specified base
address was ignored. In the non-randomized case this could result in
a range other than (i.e. starting before) the preferred one being
chosen, although the preferred range was available.
devfs_get_device() returns the device for a given path (if any), also
acquiring a reference to its vnode (thus ensuring the device won't go
away). devfs_put_device() puts the device vnode's reference.
* When registering a ram disk, a file can be specified. Its content will
be loaded into the ram disk:
echo register <file> > /dev/disk/virtual/ramdisk/control
* At any time changes to the ram disk data can be written back to the
file:
echo flush /path/to/ramdisk > /dev/disk/virtual/ramdisk/control
If not explicitly written back, the changes will be lost on reboot.
* Add a detailed listing mode (-D/--details), which prints a table with
repository/installation location name, package name, package version,
package architecture.
* Make the normal listing more compact. Now there's only one row per
package. The "Installed" column has been replaced by "Status" which
displays if/where the package is installed and whether it matches the
repository version.
We can send the data directly to the output socket instead of copying it
into a BString first, at the cost of very slightly less information in
debug output.
Somehow gcc doesn't detect the linker is GNU ld when run in Haikuporter.
We now force this in the recipe. This allows gcc to invoke the linker
with response files, avoiding "command line too long" errors, for
example when building WebKit.
* Determine whether called from userland or kernel.
* Check the buffer address via IS_USER_ADDRESS(), if from userland.
* Simplify things by merging UserRead() with Read() and
UserWrite() with Write().
