This is needed at least by rump_ext2.run as it uses the perf-counter
in the jitterentropy-lib. On other platforms the perf-counter gets enabled
by the kernel by default. However, on HW, we keep the specifier to allow users
to disable it easily (e.g. for security reasons).

The patch supports both, a download-specific UNZIP_OPT(download) and a
general UNZIP_OPT that can be defined across downloads.
UNZIP_OPT(download) overrides UNZIP_OPT.
Note, the `--strip-components=1` argument is not required for unzip.

When building Genode for VEA9X4 as micro-hypervisor protected by the ARM
TrustZone hardware we ran into limitations regarding our basic daily
testing routines. The most significant is that, when speaking about RAM
partitioning, the only available options are to configure the whole SRAM
to be secure and the whole DDR-RAM to be non-secure or vice versa. The
SRAM however provides only 32 MB which isn't enough for both a
representative non-secure guest OS or a secure Genode that is still
capable of passing our basic tests. This initiated our decision to
remove the VEA9X4 TrustZone-support.
Fixes#1351
Some downloads are available via HTTPS only, but wget < 3.14 does not
support server-name identification, which is used by some sites. So, we
disable certificate checking in wget and check the validity of the
download via SIG or SHA.
Fixes#1334.
Due to commit "run: relax IP power plug recognition + serial EOF",
when piping the serial command through 'tr', some characters might
get buffered, thereby preventing some run scripts to finish correctly.
This commit removes the 'tr' hack. Instead, to circumvent the 'expect'
problem, which kills under special conditions spawned childs used to
obtain serial line content, whenever EOF of the serial command is
recognized during the boot phase, the child process gets re-spawned.
* To communicate with IP power plug devices from Koukaam, to remote
control power supply of test boards, don't parse minor versions, but
support different IP power plugs
* TCL's expect may report an EOF when reading from the spawned serial
terminal, especially when using 'socat' to stream serial over TCP/IP,
although the spawned child is still running and delivering content.
This problem is clearly not dependent on the characters send, but
possibly due to strange pipe signals. When piping the serial output
through 'tr' the problem vanishs.
The older SOAP EOI protocol is not supported with AMT version 9+. By default
the wsman tool will be used if installed.

Until now, the rumpkernel based tools were installed with all symbols
included. This accounts for about 200MiB used space on 64Bit system.
Stripping the binaries prior to installation brings the space
requirements down to 20MiB.
Fixes#1245.
The clean rule is used to delete already built binaries as well as to
clean-up any left-overs from previous build attempts. If there was
no previous attempt just return true to prevent make from complaining.
Fixes#1245.
This provides bootable disk images for x86 platforms via
! RUN_OPT="--target disk"
The resulting disk image contains one ext2 partition with binaries from
the GRUB2 boot loader and the run scenario. The default disk size fits
all binaries, but is configurable via
! --disk-size <size in MiB>
in RUN_OPT.
The feature depends on an grub2-head.img, which is part of the commit,
but may also be generated by executing tool/create_grub2. The script
generates a disk image prepared for one partition, which contains files
for GRUB2. All image preparation steps that need superuser privileges
are conducted by this script.
The final step of writing the entire image to a disk must be executed
later by
sudo dd if=<image file> of=<device> bs=8M conv=fsync
Fixes#1203.
The build config for core is now provided through libraries to enable

Until now, the HW platform support for the TrustZone features of the

Using 'upvar' instead of 'global' in the 'append_if' and 'lappend_if'

The rumpkernel based tools are intended to be used by executing
'tool/rump'. Since it covers the most common use cases for these
tools, this script is comparatively extensive, hence giving a short
tutorial seems reasonable:
* Format a disk image with Ext2:
To format a disk image with the Ext2 file system, first prepare the
actual image by executing dd:
! dd if=/dev/zero of=/path/to/disk_image bs=1M count=128
Second, use 'tool/rump' to format the disk image:
! rump -f -F ext2fs /path/to/disk_image
Afterwards the just created file system may be populated with the
content of another directory by executing
! rump -F ext2fs -p /path/to/another_dir /path/to/disk_image
The content of the file system image can be listed by executing
! rump -F ext2fs -l /path/to/disk_image
* Create a encrypted disk image:
Creating a cryptographic disk image based on cgd(4) is done by
executing the following command:
! rump -c /path/to/disk_image
This will generate a key that may be used to decrypt the image
later on. Since this command will _only_ generate a key and NOT
initialize the disk image, it is highly advised to prepare the disk
image by using '/dev/urandom' instead of '/dev/zero' (only new blocks
that will be written to the disk image are encrypted). In addition
while generating the key a temporary configuration file will be
created. Although this file has proper permissions, it may leak the
generated key if it is created on persistent storage. To specify a more
secure directory the '-t' option should be used:
! rump -c -t /path/to/secure/directory /path/to/disk_image
Decrypting the disk image requires the key generated in the previous
step:
! rump -c -k <key> /path/to/disk_image
For now this key has to specified as command line argument. This is
an issue if the shell, which is used, is maintaing a history of
executed commands.
For completness sake let us put all examples together by creating a
encrypted Ext2 image that will contain all files of Genode's _demo_
scenario:
! dd if=/dev/urandom of=/tmp/demo.img bs=1M count=16
! $(GENODE_DIR)/tool/rump -c -t /ramfs -F ext2fs /tmp/demo.img > \
! /ramfs/key # key is printed out to stdout
! $(GENODE_DIR)/tool/rump -c -t /ramfs -F ext2fs -k <key> \
! -p $(BUILD_DIR)/var/run/demo /tmp/demo.img
To check if the image was populated succesfully, execute the
following:
! $(GENODE_DIR)/tool/rump -c -t /ramfs -F ext2fs -k <key> -l \
! /tmp/demo.img
The rumpkernel tools are used within the Genode OS Framework tool chain
for preparing and populating disk images as well as creating cgd(4)
based cryptographic disk devices.
Execute 'tool/tool_chain_rump build' to build the tools and afterwards
'tool/tool_chain_rump install' to install the binaries. The default
install location is _/usr/local/genode-rump_.
The new 'select_from_ports' function allows a target description file to
query the path to an installed port. All ports are stored in a central
location specified as CONTRIB_DIR. By default, CONTRIB_DIR is defined
as '<genode-dir>/contrib'. Ports of 3rd-party source code are managed
using the tools at '<genode-dir>/tool/ports/'.

This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.
The rationale is described in the issue referenced below.

For further information see: http://wiki.netbsd.org/rumpkernel/. In this version
I ported the central rump components to Genode in order to take advantage of
NetBSD file system implementation. The new 'dde_rump' repository contains the
Genode version of the rump libraries and a 'rump_fs' server that implements
Genode file-system-session interface. Currently ext2, iso9660, and fat
file-systems are supported.
Issue #1048
'check_installed' takes a command name as argument and tries to call 'which' in
order to find the command path. If that does not succeed, paths like '/sbin' are
'/usr/sbin' searched. On success the absolute path of the command is returned,
on failure 'exit' is called with an error message.
Issue #1048
There exist different default setups for a specific autoconf version:
* autoconf
* autoconf$(VERSION)
* autoconf-$(VERSION)
As of now, only the second option is recognized by the check in tool_chain.
This patch ensures that if one of those is present in the correct
version, it will be found and used in the build process.
Fixes#1053.
This block cache component acts as a block device for a single client.
It uses fixed 4K blocks as caching granularity, thereby implicitly reads
ahead whenever a client requests lesser amount of blocks. Currently,
it only supports a least-recently-used replacement policy.
Fixes#113
Instead of terminating tool/tool_chain when finding the first
missing tool, this patch runs all checks to completion before
bailing out. This eases finding missing programs, because the
user has to run the script only once to get a list of all missing
software.
Fixes#1046Fixes#1047
Unless '-ignorestderr' is set on 'exec' in expect, any output on stderr
is interpreted as execution failure. In this case, 'create_iso' logs
some diagnostics but does not fail.
We repeatedly promote our ISOs to be bootable from USB storage.
Therefore, we have a hard dependency on 'isohybrid' and should fail in
the case that the tool is missing.
For PBXA9 qemu adjusts provided RAM chips to the -m arg. Thus we
filter user values and force value that enables all chips that Genode
expects to be available. Not doing so leads to inexplicable errors.

If the script is executed with an obscure path (e.g.,
'../tool/autopilot'), just taking the argv0 string fails. Therefore, the
file path is now normalized prior to the directory detection.
Since dde_linux now contains the port of the Linux IP stack available for all
Genode base-* platforms move the repository out of drivers_arm and drivers_x86
build.conf to the optional build.conf (available to all platforms).

is interrupted.
Issue #748
The signature verification tool uses gpg to verify the detached

Instead of using a fixed command like picocom in the run tool,
it's better to have the flexibility to set the whole command that
connects to the serial device. Therefore, it's possible for instance
to connect to a remote serial device exported via TCP/IP by using tools
like socat.
This patch introduces a new platform 'linux_arm' for building and running
Genode/Linux on an ARM device.

mkisofs is the original ISO creation tool from cdrtools available on
many UNIX systems. genisoimage on the other hand is part of a mostly
unmaintained fork of cdrtools very specific to Debian Linux and its
derivates (e.g., Ubuntu). Fortunately, genisoimage (as we used it) is
completely invocation-compatible to mkisofs.
Fixes#627.
This base platform is no longer maintained.
For supporting the Microblaze CPU in the future, we might consider
integrating support for this architecture into base-hw. Currently
though, there does not seem to be any demand for it.
The 'Timer::Session::msleep' function is one of the last occurrences of
long-blocking RPC calls. Synchronous blocking RPC interfaces turned out
to be constant source of trouble and code complexity. I.e., a timer
client that also wants to respond to non-timer events was forced to be a
multi-threaded process. This patch replaces the blocking 'msleep' call
by a mechanism for programming timeouts and receiving wakeup signals in
an asynchronous fashion. Thereby signals originating from the timer can
be handled along with signals from other signal sources by a single
thread.
The changed interface has been tested on Linux, L4/Fiasco, OKL4, NOVA,
L4ka::Pistachio, Codezero, Fiasco.OC, and hw_pbxa9. Furthermore, this
patch adds the timer test to autopilot.

This should ensure that the directory is created before trying to
create a file within it.
This hopefully fixes errors like the following when using parallel
builds:

'Bender' can detect serial ports accessible via PCI and writes the I/O ports
to the Bios Data area (BDA).
Usage together with the PXE bootloader ease life running Genode/NOVA on native
hardware, where a standard serial device isn't available anymore anywhere.
There is no obvious reason for having two different SPEC variables, definitions,
and pathes for the Pandaboard platform. It even lead to problems regarding the
omap4 framebuffer driver (look at issue #505 and #506).
Using the new 'join()' function, the caller can explicitly block for the
completion of the thread's 'entry()' function. The test case for this
feature can be found at 'os/src/test/thread_join'. For hybrid
Linux/Genode programs, the 'Thread_base::join()' does not map directly
to 'pthread_join'. The latter function gets already called by the
destructor of 'Thread_base'. According to the documentation, subsequent
calls of 'pthread_join' for one thread may result in undefined behaviour.
So we use a 'Genode::Lock' on this platform, which is in line with the
other platforms.
Related to #194, #501
The bash-builtin 'pwd' command uses the 'st_dev' and 'st_ino' members of
the 'stat' struct to compare the path from the 'PWD' environment variable
with the path returned by 'getcwd()'. These members don't get set
correctly in Noux and therefore the 'pwd' command sometimes returns wrong
results when building Genode in Noux. With this patch the 'CURDIR' make
variable gets used instead of calling 'pwd'.
Fixes#454.
The 'build.mk' file checks if the tool chain to be used supports the
'-static' and '-fno-stack-protector' flags, but this check always fails
for the current Genode tool chain because it cannot create executable
files without explicitly specifying the 'crt0' and library files to be
linked, which the check doesn't.
This patch removes the compiler check.
Fixes#358.
With this patch the 'GNU Project Debugger' (GDB) can be built for Noux.
The included run script connects GDB and GDB monitor via a cross-link
terminal and allows interactive source-level debugging of the GDB monitor
test application on Genode.
Fixes#280.
In the create_builddir script the foc_x86_64 platform was missing
when adding x86-drivers to the etc/build.conf file. This lead to
failed run-scripts initiated by the autopilot tool.
Make pxe optional and use by default grub.
For that to work we use objcopy to repack the elf64
file into elf32.
With this commit more tests succeed. Most
tests use 64M and with that pulsar even does not start
the hypervisor. With 96M more test run however that would
mean to adjust most of the run scripts ...
Use git to get recent kernels from github. Adjust NOVA patch to compile
with recent github version. Patch and use makefile of NOVA microkernel
to avoid duplicated (and outdated) makefile in Genode
Furthermore, this patch adds support for using NOVA on x86_64. The
generic part of the syscall bindings has been moved to
'base-nova/include/nova/syscall-generic.h'. The 32/64-bit specific
parts are located at 'base-nova/include/32bit/nova/syscalls.h' and
'base-nova/include/64bit/nova/syscalls.h' respectively.
On x86_64, the run environment boots qemu using the Pulsar boot loader
because GRUB legacy does not support booting 64bit ELF executables.
In addition to the NOVA-specific changes in base-nova, this patch
rectifies compile-time warnings or build errors in the 'ports' and
'libports' repositories that are related to NOVA x86_64 (i.e., Vancouver
builds for 32bit only and needed an adaptation to NOVAs changed
bindings)
Fixes#233, fixes#234
The new 'dde_linux' repository will host device drivers ported from the
Linux kernel. In contrast to the original 'linux_drivers' repository,
'dde_linux' does not contain any 3rd-party source code. To download the
Linux kernel source code and extract the drivers, execute the 'make
prepare' rule of the top-level Makefile. The initial version of the
'dde_linux' repository comes with an USB driver. The porting methodology
follows the path of the Intel GEM port. Instead of attempting to provide
a generic Linux environment that works across drivers, each driver comes
with a specially tailored DDE.
The DDE consists of Genode-specific implementations of Linux API
functions as declared in 'lx_emul.h'. Most of these functions are
dummies that must merely be provided to resolve dependencies at the
linking stage. They are called by unused code-paths.
As of now, the USB driver support UHCI, EHCI on the x86_32 platform. I
exposes USB HID devices and USB storage devices via Genode's input-session
and block-session respectively.
The USB driver is accompanied with two run scripts 'run/usb_hid.run' and
'run/usb_storage.run'.
The Lua runtime library is built in two variants: ANSI C and C++. The
C++ provides all Lua API function with C++ linkage and uses C++
exceptions instead of setjmp/longjmp for protected execution of Lua
chunks.
The ported version of Lua is 5.1.5.
The build system overlays multiple source trees (repositories) such that
they can shadow libraries and include search paths. This patch extends
the shadowing concept to build targets. Furthermore, it streamlines the
build stage for generating library depenencies, reducing the processing
time of this stage by 10-20 percent. Fixes#165.
In the compare_output_to function in the run tool a check was introduced,
whether the given arguments are empty, and if so if the output string is it
too. Without this patch compare_output_to succeeded when the given pattern
was empty but output wasn't. Please refer to issue #162.
In addition to autogen and autoconf, the tool-chain build script
requires ncurses (for building GDB), wget (to download the tool-chain
source code), and texinfo. Let the tool check if these packages are
installed instead of failing later during the build.
