Replace packet method 'T *data' by the new methods 'T &reinterpret_data'
for parsing or modifying existing sub-protocol packets and 'T
&construct_at_data' for composing a new sub-protocol packet. This has
the advantage that, when composing a new packet, the default constructor
that zero-fills the packet is always called first.
Fixes#2751
Our nightly did not detect the current stale hashes because only updated
(in the sense of a changed hash) ports are prepared. Others were left
untouched besides the check_port_source step. Now, check_hash also
checks for missing hash file updates.
This commit changes the 'Input::Event' type to be more safe and to
deliver symbolic character information along with press events.

By now, rump would query its available RAM quota to determine the
memory limit minus some RAM reserved for Genode meta-data. This
does not work when the VFS rump plugin is used as the available
quota belongs to the VFS server. In this case the memlimit should
be set by specifing the RAM in the plugin's config, e.g.:
! <vfs>
! <rump fs="ext2fs" ram="64M" writeabl="yes"/>
! </vfs>
Fixes#2783.
In Vm_space::map when allocating a new page-table-entry selector, the
allocator may throw an exception that there are no selecztors left which
was not caught by now. Now, we catch this exception, flush the mapping
cache to free all selectors again and retry to allocate.
Fixes#2781
On the Raspberry PI, the 2 seconds of round time in the polling test
were not sufficient to reach the goal of at least 1000 successful polls.
Thus, the commit sets the round time to 2.5 seconds which doesn't hurt to
much but allows the RPI to just make it.
Fixes#2779
SHA1 is susceptible to collision attacks and is generally deprecated.
Source code archives are particularly vulnerable because the hash digest
can be tweaked by hiding by arbitrary data in code comments and files
not processed during build.
With this in mind the 'prepare_port' tool now attempts to verify digests
as SHA256 with a fallback to SHA1. When CHECK_HASH=no is set the tool
will refuse to verify digests as SHA1. The use of SHA1 for creating
unique port versions is retained because the hashes are produced locally
from inputs stored in a git history.
Issue #2767
This patch largely reverts the feature of selecting parts of input nodes
from within the output node (as originally introduced by commit
7263cae5a18b4f1f2293d031f9bafcf05ba51146). The selection of content
should be consistently performed by input nodes instead. The principle
ability of copying input nodes verbatim into the output stays available.
Issue #2691
The new 'attribute' and 'value' attributes of input nodes
can be used to select input sub nodes that match the presence and value
of the specified attribute.
Issue #2691
By incorporating the sculpt version into the path where customizations
are stored, we can update and roll back sculpt versions without risking
configuration incompatibilities. By default, the sculpt version
corresponds to <genode-dir>/VERSION.
The condition must first check the io-buffer length and then check the
content. Otherwise, cat'ting a file that is padded with zeros up to
page size (io-buffer size) yields an out-of-range read access.
This patch replaces the terminal's formerly built-in fonts with the new
VFS-based font handling.
To avoid the copying of the terminal's font configuration across run
scripts, this patch adds the new terminal/pkg runtime package, which
includes everything needed for instantiating a terminal: the actual
terminal component, the library dependencies (vfs_ttf, which in turn
depends on the libc), a font (bitstream-vera), and a reasonable default
configuration.
Fixes#2758
The 'stat' method is called for all paths, not just the specific file
system node of the ROM module. The ROM update is needed only in the
latter case.
Otherwise, when always updating the ROM on stat, stat calls on the VFS
become very expensive in the presence of a mounted ROM module if the ROM
is obtained from fs_rom (which re-watches the file and all its
individual path elements whenever the 'update' RPC function is called).
This patch make the scenario independent from device drivers, which were
solely needed to display a graphical terminal. The output of the
scenario is now printed via the log_terminal component, which makes the
logging output of nightly tests more useful.
The pattern rule picked up the wrong platform_services.cc in the
depot-archive case only because the archive integrates generic and
sel4-specific source files into REP_DIR.
