To select a different keyboard layout than the default 'en_us', override the
'language_chargen' function in your run script (after including
qt5_common.inc):
proc language_chargen { } { return "de" }
where "de" refers to the character map file
'repos/os/src/server/input_filter/de.chargen'
Issue #2264
If 'close' does not call 'unlink' like 'shutdown', the Lxip_socket_dir
never gets destroyed and thus the socket server leaks resources like
RAM and ports.
Ref #2285
Our 'shutdown' implementation handles only the case that 'how' is 'RDWR'.
Thus, print an error and continue if a user calls it with another value.
Fixes#2285
If 'Libc::Kernel::resume:all()' is called from a non-main thread, send a
signal to unblock the main thread from 'wait_and_dispatch_one_signal()'.
Fixes#2283
The 'server_ip' and 'server_port' attributes for 'lxip/udp_client' and
'lwip/http_clnt' as well as the 'port' attribute for 'lxip/udp_echo' and
'lwip/http_srv_static' are not directly libc-related so they should not
live in the libc tag but in the config tag of the component.
Ref #2193
Libc components cannot use regular calls to select() as this may suspend
their execution. In this case incoming RPCs will be deferred until
select() returns and the component returns to the entrypoint dispatch
loop. The Libc::Signal_handler solves this problem with a its select()
that either returns the currently ready file descriptors immediately or
calls the registered handler function during libc resume.
Now, the libc kernel supports to execute application code from all RPC
functions not only Component::construct(). This is enabled by the
Libc::with_libc() scope function.
This commit extends an easy-to-use mechanism to allow Genode component
code to enter/leave the libc application context. This is needed
whenever low-level component code (like signal handlers or RPC
functions) need to interact with potentially blocking libc I/O
functions.
Please note that this commit contains the API-level design only. The
actual context switching code 'execute_in_application_context' is
missing.
The socket file system can be configured in the "socket" attribute of
the libc config node like follows.
<vfs> <dir name="socket"> <fs/> </dir> </vfs>
<libc ... socket="/socket"/>
This configures the socket file system libc backend to access files in
"/socket" for socket operations.
The read-ready packet informs the server that the client wants to be
notified if a handle becomes readable. When becoming readable, the
server acknowledges packet and the client may queue a read requests
accordingly.
This change introduces a Genode specific init function, which sets the
backend allocator used by jent_zalloc/zfree(). As consequence the
library can solely be used by native Genode components, direct libc
usage is not supported.
Fixes#2274.
This patch eliminates the need for a global allocator by passing the
parent-service registry as argument to the 'Slave::Policy' constructor.
Fixes#2269
The support has two parts. First, a VFS plugin now gets passed an
I/O-response handler callback on construction, which informs users of the
VFS that an I/O event occurred. This enables, for example, the libC to
check if blocking read can be completed. Further, the VFS file I/O
interface provides now functions for suspendable reads, i.e.,
queue_read() and complete_read().
This test reproduces an issue of the VFS block file system when the
underlying block device has a coarser granularity than the block
requests issued by the VFS client. I.e., if the underlying block device
has a block size of 4K, writing a sequence of (non-4K-aligned) 512 blocks
that crosss a 4K boundary corrupts the data on the block device.

This commit enables compile-time warnings displayed whenever a deprecated
API header is included, and adjusts the existing #include directives
accordingly.

Parse ``<env key="..." value=".."/>`` nodes from the config ROM and
populate a list at the 'genode_envp' and 'environ' symbols.
