The DHCP client of the NIC router used to end up in an uncaught exception if
an IP address in the DNS server option of a DHCP ACK was invalid. This commit
makes the 'Dns_server' constructor (where the exception originated from)
private and instead introduces a public lambda method 'construct' that calls
one lambda argument on success and another on failure. This is also in line
with the most recent changes to the 'find_by_*' methods of other classes in
the NIC router and contributes to the goal of reducing expensive exception
handling.
Fixes#4465
The Interface class of the router is an abstraction for NIC client sessions,
NIC server sessions, and Uplink sessions. Nonetheless, Interface generally used
to use the packet stream types of the Nic namespace and it worked because the
Uplink packet stream types are factually the same (the are typedef'd from the
same base type templates with the same parameters).
The initial intention of this issue was to remove dependency on the diverse
packet stream stream types from Interface. However, this turned out to be more
tricky than thought. The Interface class calls function templates on the packet
stream types, making a generic virtual interface impossible. And moving the
calling code to the session classes as well would produce a lot of redundancy.
Therefore, this commit removes only the use of the Nic namespace in the
interface.* files by typedef'ing the packet stream types from the generic
Genode type templates with the same parameters as in Nic and Uplink.

The updated Bender version is configurable regarding the mode in which to run
the Intel HWP plugin. This can now be controlled via the new run option
'--bender-intel-hwp-mode' (only when running on NOVA). The option knows 4 valid
values 'off', 'performance', 'balanced', and 'power_saving'. When running on
NOVA, the default value applied by the run tool is 'performance'. when running
on any other kernel, the default value of Bender ('off') is used. Therefore,
when not setting the new '--bender-intel-hwp-mode' flag, the behavior is the
same as before this commit.
Fixes#4224
The libc kernel used to silently go on if one of the files given through
stdin/stdout/stderr or <fd path=""> was missing (with possibly vital
functionality for the component not working). A pointer to the presumably
simple configuration issue of the underlying scenario was not given to the
user.
With this commit, the libc kernel prints a descriptive warning before
proceeding with the invalid file descriptor
Fixes#4218
The libc kernel used to end up in an uncaught exception if one of the
directories in the paths given through stdin/stdout/stderr or <fd path=""> was
missing. The resulting error didn't point the user to the presumably simple
configuration issue of his scenario in any way and killed the affected
component.
With this commit, the libc kernel prints a descriptive warning instead and
simply continues to run the component with the corresponding file descriptor
missing. At least in case of stdin/stdout/stderr, the libc deals gracefully
with this approach.
Ref #4218
If provided with a config that does not include a `<static>` or
`<common_routes>` node, depot_deploy exits due to a `Nonexistent_sub_node`
exception. Instead, we should output a more useful warning.
Fixesgenodelabs/genode#4600
The `with_sub_node` method is renamed to `with_optional_sub_node` to
better reflect that the non-existence of a sub node with the desired type is
ignored.
At the same time, the new `with_sub_node` now takes a second functor that is
called when no sub node of the desired type exists.
genodelabs/genode#4600
This patch refines the rules for generating a base-hw src archive
for a given board by enumerating the content of the lib/mk/spec/*
directories instead of including entire directories. This avoids
the inclusion of lib.mk files found in SoC-specific repositories
(like genode-allwinner) in the kernel source archives.
When building a binary archive from such a src archive with the changes
of issue #4599, the build system would otherwise try (and fail) to build
the libraries for the accidentally included lib.mk files.
The 'file' library makes the gems API depend on the libc, which is not
desireable because most users of the gems API have no direct libc
dependency.
With the changes of issue #4599, the build of each src archive that
depends on the gems API would attempt to build the 'file' library and
thereby demand the libc.
Note that the 'file' library is a relic that should better not be
promoted as part of the gems API. Hence, this patch removes the file
library from the gems API and adds it to the src archives of the few
remaining users.
Issue #4599
The 'base-linux' API is used by hybrid Genode/Linux programs for the
lx_hybrid library. This API archive happend to contain other libraries -
like seccomp - that are solely needed for building core. With the change
of the build system in issue #4599, the build system would attempt to
build all libraries instead of merely the library dependencies of the
available targets. Hence, it would trigger the build of, e.g., the
seccomp library for each user of the base-linux API.
This patch avoids these superfluous build steps by pruning the content
of lib/mk/ to the libraries actually needed for lx_hybrid users.
Issue #4599
This patch make the use of the result of the 'build_artifacts' function
as input for 'build_boot_image' more robust. Since 'build_artifacts'
obtains binary names from the progress.log, the names of core,
ld.lib.so, and the timer correspond to the kernel-specific names.
However, 'build_boot_image' expects the kernel-agnostic names as
arguments. Kernel-specific files need special treatment when integrated
in the boot image: the kernel-specific file is copied and renamed to the
kernel-agnostic name. Without this patch, the kernel-specific file is
copied as is (e.g., ld-nova.lib.so). So the name of the ROM module is
wrong. This patch resets the kernel-specific names to the generic names
so that the special-case handling comes into effect.
The ld.lib.so stub library generated by base/lib/mk/ld.mk has no
purpose at runtime. On the contrary, it must not be integrated into the
boot image because its name collides with the kernel-specific dynamic
linker.
The build system automatically announces the names of shared libraries
as build artifacts. However, in rare cases, it is required to manually
define them. In particular, the 'ld' stub library plays no role at runtime
and should not be integrated into the boot image.
This patch adds a customization hook following the same pattern as used
for target.mk files, namely the BUILD_ARTIFACTS variable. If defined,
its value is taken as the list of boot artifacts generated by the
library-description file.
Issue #4368
This patch adds special handling for lib/<libname> arguments to the
build system, which supersedes the former LIB=<libname> mechanism.
Whereas the old mechanism was limited to a single library, the new
convention allows multiple library arguments, similar to regular
targets. The change brings the two immediate benefits.
First, the streamlining of library and target arguments allows for the
building of libraries via the 'build' command of the run tool.
Second, it alleviates the need for pseudo target.mk files for building
shared libraries that have no direct dependencies, in particular VFS
plugins.
Since this change eases the explicit creation of shared libraries
from run scripts, we may reconsider the automatic implicit building
of shared libraries driven by targets. E.g., while developing a Qt
application, a run script could import the Qt libraries from the
depot and combine those with the developed (fresh built) target without
triggering the build of the Qt libraries in the build directory.
When issueing 'make' without arguments, all targets are built. This
patch applies this behavior to libraries as well, thereby removing the
need for the base/src/lib/target.mk pseudo target as used by the CI
tools to build all libraries.
Note that target.mk files located under src/lib/ are no longer
reachable. Therefore, all run scripts that used to trigger the
build of a shared library via a pseudo target must be adapted.
E.g., 'build lib/vfs/tap' must be replaced by 'build lib/vfs_tap'.
With this patch, the LIB=<libname> option is no longer supported.
Fixes#4599
changes. The alternative settings get reread on all interfaces as done before
"qemu-usb: fix device endpoint update" commit by introducing specific
reset_alt_settings function. The fallthrough case was intentionally before
the "qemu-usb: fix device endpoint update" case, which now is wrong.
Issue #4596
This style is used by the upcoming phone version of Sculpt for GUI
elements that are supposed to stand out a little bit more than the
regular frame style.
This patch enhances menu_view with the optional configuration attributes
'opaque' and 'background'. Setting 'opaque' to "yes" suppresses the use
of the alpha channel at the GUI session. This improves the drawing
performance by 20% on the PinePhone. Since the menu_view uses the
gems/gui_buffer.h utility, the 'Gui_buffer' received a new 'Alpha'
argument at construction time.
The 'background' attribute can be specified to define the reset color of
the GUI buffer. It alleviates the need to create a frame widget for the
top level.
The patch also switches the optimization level for compiling menu_view
to -O3, which increases the drawing performance on the PinePhone by 30%.
Fixes#4592
This change increases the quota to allow the use of bigger fonts, and
tweaks the style such that the keyboard gets a decent appearance on the
PinePhone's 1440x720 display.
This patch adds principle support for using a USB-net modem as
mobile-data uplink. The change is motivated by the upcoming phone
manager for the PinePhone where the modem serves as the primary network
uplink. For the regular PC version of Sculpt, the feature is not needed
(hence remains disabled) because USB net can be deployed from a package
as described in:
https://genodians.org/jschlatow/2021-07-21-mobile-network
The patch also renames the "Local" network option to "Disconnected" to
be more intuitive.
By decoupling the network dialog's menu view from the 'Network' class,
we become able to host the network dialog in the same menu view instance
as other dialogs.
This patch allows the sculpt manager hosted in the leitzentrale
subsystem to observe the toggling between the runtime and the
administrative GUI. This enables alternatives to the use of the
gui_fader for switching between both views. In particular, the
upcoming phone_manager toggles the visibility of its own GUI
depending on the leitzentrale state.
In a Sculpt system based on the upcoming phone_manager, the event filter
obtains its static configuration from /config/managed/event_filter.
Without the requirement for changes at runtime, there is no need to
have the phone_manager in the loop after all.
Without this patch however, this file was always initialized with the
template gems/sculpt/event_filter/default, which was presumably used
only at boot time until the sculpt manager has produced the first
generated event-filter configuration.
This patch applies the choice of optional configs - i.e., a custom
event_filter config - to both the config/ and the initial content of
config/managed/. So in cases where the /config/managed/event_filter
remains entirely static, the latter properly reflects the choosen
variant.
