For better or worse we have no proper way of handling this right now
but contrib libraries, e.g. glib, use it to determine if they can use
the underlying fd.
Fxies #3265.
This patch handles version collisions of binary archives. If a binary
archive for an (automatically) updated src-archive version already
exists in the depot, the extract tool removes the binary archive because
its existing content may stem from another src content (a version from a
different topic branch). This ensures that the new version is always
built, not skipped, when 'UPDATE_VERSIONS=1 REBUILD=' is specified.

Issue #3111
- enable vt-x in kernel configuration
Kernel patches:
- add unrestricted guest support
- avoid kernel boot failure when vt-x is not available
- avoid nullpointer in kernel when vcpu is not fully setup
- avoid vcpu scheduling bug which causes starvation on same/below prio level
- save efer register correctly from guest
The '_currently_constructed' pointer caches the information about which
'Launched_child' is currently configured in the menu. When discarding
the runtime (e.g., when un-using a file system) at this point, this
cached pointer was not invalidated while all 'Launched_child' objects
would be freed (including the currently constructed one). On the next
attempt to construct a new child, the sculpt manager attempted to
destruct the 'Launched_child' referred by the (now outdated)
'_currently_constructed' again.
Fixes#3240
Until now, Genode referenced a fork of the outdated elfloader-tool
to enable bootstrapping of sel4 on ARM platforms. Because the
elfloader is inherently dependent on the used platforms newer
ARM versions supported by the kernel could not be loaded by the
outdated elfloader. This commit uses a fresh fork of the nowadays
used sel4_tools repository.

This commit handles the corner case where a package could be installed
successfully but the package's runtime definition is inconsistent with
the content delivered by the package's dependencies, i.e., the <content>
of the runtime file lists ROM modules that do not exist.
With this patch, the '+' menu shows the message "installed but
incomplete" whenever a package is in such a state.
Issue #3241
The new configuration attributes <tcp-forward to_port="123" /> and
<udp-forward to_port="123" /> enable manipulating the destination port of
port-forwarded packets.
Fixes#3237
The required memory of the VMM depends on the VM memory configuration (vbox)
and the available screen resolution. Check for insane configurations in the
beginning to avoid late surprises.
Issue #3216
The "Vfs::Vfs_handle" type should not contain any public members that
can be initialized by the VFS internally and by the application, so
remove inheritance from the "Genode::list::Element" class. The VFS
plugins must instead use lists of "Vfs::Vfs_handle" sub-classes, the
lifetime of which are always managed by the plugin.
Ref #3036
Use a single timeout scheduler passed during lxip instantiation for
both timers and 'schedule_timeout' facilites rather than instantiate
two timer sessions and signal handlers. This reduces the library's
capability cost and initialization time.
Fix#2961
The old inline assembly provided two output operands that were afterwards
combined for a return value. However, the second output operand isn't
necessary when using the "Acquiring a Lock" example-code of the ARM manual
"Barrier Litmus Tests and Cookbook". This saves two logical operations
per acquisition try. Additionally better documentation is now provided.
Fixes#1292
This patch adds the items necessary for building Genode components with
stack protection enabled, but it is not initialized at runtime. They are
provided at the moment as a convenience and do not implement a security
feature.
Fix#3066
