.SHELLFLAGS is extended by option pipefail to make pipes fail if any pipe
element fails. As .SHELLFLAGS is exported into sub-make instances it
must be unexported before calling third-party build systems recursively.
This is a follow-up fix for "mk/ld.mk: trigger kernel-dependent
ld.lib.so build", which alleviates the need to specify the KERNEL at the
build-system command line. Thanks to Piotr Tworek for reporting.
Issue #4320
This patch works around 'tar' erroring out when faced with an empty list
of files:
tar: Cowardly refusing to create an empty archive
This can happen when using sculpt.run for a scenario with only a runtime
but no deploy or launcher configuration.
Issue #4369
With the kernel-specific build of the dynamic linker triggered
automatically at the build stage, the artificial build step at the
boot-dir stage can be skipped.
Issue #4320
The new function 'build_artifacts' returns a list of artifacts created
by the Genode build system. The list can be supplied as argument to
the 'build_boot_image' function.
Note that the list covers only program targets and shared libraries.
Other artifacts created as side effects of custom rules are not covered.
Fixes#4368
This patch prevents the run tool from issuing 'make' in the build
directory if no build targets are specified, which prompts the build
system to build everything.
If only versioned archives are supplied to a depot function like
'create_tar_from_depot_binaries', the depot/create tool is called
with zero arguments, resulting in a help message. The patch detects
this case and skips the call.
Since unifying the build directories accross architectures, the special
case of the 'linux' platform is no longer needed. Linux can be targeted
from regular CPU-architecture-specific build directories via:
KERNEL=linux BOARD=linux
Fixes#4366
This change keeps the version-controlled 'pubkey' and 'download' files
separate from files generated via depot/create or downloaded via
depot/download. So one can remove the entire depot/ directory without
interfering with git.
Furthermore, depot keys can now be hosted in supplemental repositories
independent from Genode's main repository.
Fixes#4364
This patch discharges the dependency of Makefile.in from Makefile.am
files whenever both files are present in a downloaded archive.
Being based on make, the trigger of running automake is based on the
timestamps for the extracted archive content. However, since we reset
the timestamps (via 'tar -m') at extraction time, no assumptions about
the timestamp relations between the extracted files can be made. In the
event automake is triggered, we are faced with the tool dependency from
a specific automake version on the host.
The patch enforces the unconditional use the 'Makefile.in' version
supplied by the archive.
Fixes#4350
Always instantiating a network device with id `net0`, removes the need to call
append_qemu_nic_args in run scripts unless we want to add forwarding
rules.
genodelabs/genode#4311
Allow specifying additional qemu arguments for externally supported boards
(e.g. zynq_qemu) by adding a `qemu_args` file in the board-property directory.
The syntax of the qemu_args file is as follows:
- Arguments can appear in a single line or in multiple lines as the
lines will be appended (separated by a whitespace) to the global
qemu_args variable.
- If the line is prepended with a `foobar:` expression. The arguments
are only added if the foobar spec is present.
Note, that a `-m` argument specified in the qemu_args file will
override the arguments provided by the run scripts.
genodelabs/genode#4311
First, the former implementation has only considered the pure numerical
variant of the -m argument. Yet, qemu also allows specifying the amount
of memory by `-m 1G`, `-m size=1G` and more.
Second, the default amount of memory for BOARD=pc was 512M (800M in case of okl4).
Since the depot_autopilot.run also required at least 768M on all
platforms it seems reasonable to take 800M as a default value for BOARD=pc and
thereby remove the special treatment of okl4.
genodelabs/genode#4311
Now that we have appropriate native driver for them add keyboard and
mouse devices to virt_qemu machine. Make sure qemu exposes those new
devices in modern, VirtIO 1.0 mode. At leasts qemu 5.1.0 still uses
pre 1.0 mode in default setup.
Issue #4282
The former encoding was UTF-8, which works quite well if LC_CTYPE is
ensured to be an UTF-8 codeset (e.g., en_US.UTF-8 or C.UTF-8 . But, if
LC_CTYPE is set to C or latin1 for example, the Tcl regex library enters
an infinite loop because of unexpected characters used as markers
n the strings (e.g., SECTION SIGN U+00A7).
Therefore, the extract tool was converted to latin1 with the following
commands and now works for LC_CTYPE C and UTF-8 codesets.
iconv -f utf-8 -t latin1 tool/dts/extract > /tmp/e
cp /tmp/e tool/dts/extract
The NIC router used to ignore the IPv4 header fields "More fragments" and
"Fragment offset" completely. Therefore higher-level protocols of fragmented
IPv4 were interpreted wrong because each fragment was considered a self-
standing packet, expecting, for instance UDP/TCP headers somewhere inside of
the UDP/TCP data field. Normally, such packets were dropped as soon as the
UDP/TCP checksum check failed because of the misinterpretation. However,
it was also possible for fragmented IPv4 to pass the router although normally
only partially.
IPv4 fragmentation support in the router would introduce some potential
security risks and is presumably not an easy endeavor. So, for now, we settled
on not supporting IPv4 fragmentation. With this commit, the router simply drops
all fragmented IPv4. This is reflected to the log for each fragment as "drop
packet (fragmented IPv4 not supported)" when 'verbose_packet_drop="yes"' is
configured.
The new test 'run/nic_router_ipv4_fragm' is an automated test for this
behavior. The test is added to the autopilot list.

This patch lifts the limitation for 32-bit ARM platforms and makes the
parameter --load-fastboot-device optional. If only one device is
present, it can be omitted.
Fixes#4232
This patch replaces the enumeration of boards in the drivers_nic_pkg and
drivers_interactive_pkg functions by inferring the package names from
the [board] name. This eases the addition of driver packages in external
repositories.
Fixes#4221
The depot tool 'build_bin_archive' used to ask only whether CCACHE is empty or
not and, if it wasn't empty, the tool added 'CCACHE := yes' to the build.conf
of the temporary build dir. This caused the sub-build processes to use ccache
even when the top-level CCACHE variable was set to a bogus value.
Also adds documentation of the CCACHE variable to the help message of the
'build' and 'build_bin_archive' tool.
