LwIP skips a packet copy by wrapping Nic stream buffer regions in LwIP
pbuf objects. Move from a fixed size array to a potentially unbounded
slab allocator for managing this buffer metadata.
Ref #2335
A 'QThread' can be reused when its execution is finished by calling
'QThread::start()' again. Before this commit, this created a new Genode
thread, but did not destroy a previously finished Genode thread first.
Fixes#2928
This patch reintroduces the LwIP stack to libc as a VFS plugin
implementing the socket_fs interface. Rather than use LwIP's socket
emulation layer this plugin interfaces directly to LwIP raw API and is
single threaded.
The internal TCP parameters of the stack are untuned.
Fix#2050Fix#2335
Calling 'handle_io_response()' in a regular VFS function (in contrast to a
post-signal hook) can cause problems if the caller of the VFS function holds
a lock which prevents the io response handler from returning.
With this commit, the user of the VFS becomes responsible for unblocking
threads which might be blocking after a failed 'queue_read()', 'queue_sync()'
or 'write()' call.
Fixes#2896
This patch removes the detection of statically linked executables from
the base framework. It thereby fixes the corner cases encountered with
Sculpt when obtaining the binaries of the runtime from the depot_rom
service that is hosted within the runtime.
Statically linked binaries and hybrid Linux/Genode (lx_hybrid) binaries
can still be started by relabeling the ROM-session route of "ld.lib.so"
to the binary name, pretending that the binary is the dynamic linker.
This can be achieved via init's label rewriting mechanism:
<route>
<service name="ROM" unscoped_label="ld.lib.so">
<parent label="test-platform"/> </service>
</route>
However, as this is quite cryptic and would need to be applied for all
lx_hybrid components, the patch adds a shortcut to init's configuration.
One can simply add the 'ld="no"' attribute to the <start> node of the
corresponding component:
<start name="test-platform" ld="no"/>
Fixes#2866
The verbosity mode of the NIC bridge can be toggled with the verbose attribute
(default value shown):
! <config verbose="no" />
If enabled, the NIC bridge logs sent and received packets as well as the
lifetime of interfaces connected to the bridge.
Issue #2899
Do not generate invalid configurations for the uplink domain anymore. If
some tests are disabled and therefore their routing rules at the uplink
domain would be invalid, spare out these routing rules.
Issue #2899
Also remove 'requires_installation_of', while also checking sbin
directories in 'have_installed'. The run scripts have been adjusted
accordingly.
Fixes#2853
- initialize the stack size attribute with `Libc::Component::stack_size()`
as default value
- remove the possibly uninitialized `pthread` member from the attribute
structure and obtain current attribute values in the
`pthread_attr_get_np()` function, where the `pthread` object reference
is given as argument
- let each thread obtain its stack address and actual stack size at thread
start to have the information available for other threads
Fixes#2865
The libc will now use the file given by the 'nameserver_file' attribute
to get the DNS nameserver address instead of reading '/etc/resolv.conf'.
It defaults to '/socket/nameserver' which is the common location when
using the lxip VFS plugin. As a constraint the libc will read the first
line and expects the nameserver address without any keywords in front of
it.
Fixes#2861.
Merge the configuration from raw/pdf_view into the pkg/pdf_view runtime
file. Request a File_system session and load files from there, rather
than by ROM.
Ref #2859
The component is no longer loads from '/test.pdf', the first PDF file
found in the root directory of the file-system is loaded automatically.
The behavior cannot be overridden by configuration.
Feed MuPDF with characters from input events to MuPDF rather than
translate raw key codes to ASCII. This enables almost all MuPDF key
bindings without the need to maintain a lookup table. Mouse navigation
has been enabled as well. To print the key-bindings to log, press '?'.
