By using &&, we prevent the accidental copying of deallocator instances,
passed to the destroy function. We always want to take the deallocator
as reference or pointer.
For the correct integration of a QPluginWidget in a parent QWidget, with
this commit the parent QWidget's Nitpicker view is made the parent view of
the plugin's Nitpicker view.
Fixes#1173.
This commit adds a 'parent_view()' function to the loader session, which
allows to set the parent view of the subsystem's Nitpicker view.
If the function is to be used, this must get done before calling
'start()'.
Fixes#1172.
In file
src/VBox/Additions/WINNT/SharedFolders/driver/file.c
the function
static int vbsfTransferCommon(VBSFTRANSFERCTX *pCtx)
in the
VbglR0CanUsePhysPageList()
branch does not correctly evaluate the read or written bytes from
the VMM. It ever assumes that whole pages are read/written.
Workaround the bug in the Windows guest additions of Vbox until fixed
upstream by filling up the read/write buffer completely within the VMM code
of Vbox.
Fixes#1176
Genode::strncpy() enures the destination string is null terminated by
writing a null-byte. In this case, the null-bytes always overwrote the
last character of the output byte stream.
Ensures that the Exynos5 CPU is clocked equally no matter how the kernel
initialized it. This makes the result of this time critical test more
comparable.
fix#1162
Now that it is possible to resize the stack of the Genode main thread, it
is not necessary anymore to create a new Genode thread as Qt main thread.
Fixes#1134.
This patch changes both the Input::Session interface and the skeleton
for the server-side implementation of this interface
('input/component.h').
The Input::Session interface offers a new 'sigh' function, which can be
called be the client to register a signal handler. The signal handler
gets notified on the arrival of new input. This alleviates the need to
poll for input events at the client side.
The server-side skeleton for implementing input services underwent a
redesign to make it more modular and robust. I.e., there are no
global functions needed at the server side and the event-queue
enable/disable mechanism is implemented at a central place (in the root
component) rather than inside each driver.
Fixes#46
Fixes an alignment problem introduced by commit "hw: map core on demand"
where physical address alignment wasn't checked anymore, when inserting
a section within the first-level table of ARM's short translation table
format.
Many thanks to Christian Prochaska for helping to debug the problem.
In case the storage-entry point dispatches more then one packet, wait for the
previous command to finish before setting a new request. This has to be done
because the 'queuecommand' does actually *not* queue things, but can only handle
one request at the time.
Fix#1143
On ARM, when machine instructions get written into the data cache
(for example by a JIT compiler), one needs to make sure that the
instructions get written out to memory and read from memory into
the instruction cache before they get executed. This functionality
is usually provided by a kernel syscall and this patch adds a generic
interface for Genode applications to use it.
Fixes#1153.
The 'rump_cgd' server provides block level encryption for a block
session by employing the 'cgd(4)' device provided by the rumpkernel.
'rump_cgd' uses a Block_session to get access to an existing block
device and provides another Block_session to its clients. Each block
written or read by the client is transperently encrypted or decrypted
by the server.
For now 'rump_cgd' may only _configure_ a 'cgd' device but is unable
to generate a configuration. The used cipher is hardcoded to
_aes-cbc_ with a keysize of 256 bit. Furthermore the server is able to
serve one client only.
To ease the usage, its interface is modelled after the interface of
'cgdconfig(8)'. As implications thereof the key must have the same
format as used by 'cgdconfig'. That means the key is a base 64 encoded
string in which the first 4 bytes denote the actual length of the key
in bits (these 4 bytes are stored in big endian order).
Preparing a raw (e.g. without partition table) encrypted Ext2 disk
image is done by executing 'tool/rump':
! dd if=/dev/urandom of=/path/to/disk_image
! rump -c /path/to/disk_image # key is printed to stdout
! rump -c -k <key> -F ext2fs /path/to/disk_image
To use this disk image the following config snippet can be used:
! <start name="rump_cgd">
! <resource name="RAM" quantum="8M" />
! <provides><service name="Block"/></provides>
! <config action="configure">
! <params>
! <method>key</method>}
! <key>AAABAJhpB2Y2UvVjkFdlP4m44449Pi3A/uW211mkanSulJo8</key>
! </params>
! </config>
! <route>
! <service name="Block"> <child name="ahci"/> </service>
! <any-service> <parent/> <any-child/> </any-service>
! </route>
! </start>
the Block service provided by rump_cgd may be used by a file system
server in return:
! <start name="rump_fs">
! <resource name="RAM" quantum="16M"/>
! <provides><service name="File_system"/></provides>
! <config fs="ext2fs">
! <policy label="" root="/" writeable="yes"/>
! </config>
! <route>
! <service name="Block"> <child name="rump_cgd"/> </service>
! <any-service> <parent/> <any-child/> </any-service>
! </route>
! </start>
Since 'tool/rump' just utilizes the rumpkernel running on the host
system to do its duty there is a script called 'tool/cgdconf' that
extracts the key from a 'cgdconfig(8)' generated configuration file
and also is able to generade such a file from a given key. Thereby
the interoperabilty between 'rump_cgd' and the general rumpkernel
based tools is secured.
On ARM in one way or another 'string.h' prototypes will be used. Move
the definitions from rump_fs to the rump library because it is needed
by all rump based servers running on ARM.
Issue #1141.
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.
