Using 'upvar' instead of 'global' in the 'append_if' and 'lappend_if'
functions makes it possible to use these functions with local variables
of the calling function.
Fixes#1137.
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/'.
Issue #1082
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.
Issue #1082
It covers bugs which we should detect and fix, especially depending on
the result of pthread_myself locking implementation (ours and vbox) takes
decision to take a lock or just to assume it is a reentrant locking attempt.
Fixes#1128
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.
ref #964
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).
