27b1017fe9 test/lxip_raw: test using Genode socket C-API directly
The lxip_raw.run script will spawn a client/server scenario that tests
Genode C-API calls. The scenario can be used standalone, meaning no
actual network card is required.

42d9640443 lxip: update to Linux 6.1.20
This commit updates lxip from version 4.4.3 to 6.1.20. It uses the
current lx_kit approach and is a shared library again. The stack has
been tested for x86_32/x86_64/arm_v6/arm_v7/arm_8.

The C-interface of the IP stack can be found under
lxip/include/genode_c_api/socket.h.

CONFIG_X86_USE_PPRO_CHECKSUM is a 'def_bool y' and gets re-enabled by
'make olddefconfig'. The PPRO version contains text relocations which we cannot
have in binaries (e.g., 'lea 45f(%ebx ...).').

1336b0a751 mmio: upper-bounds checks
The classes Genode::Mmio, Genode::Register_set, Genode::Attached_mmio, and
Platform::Device::Mmio now receive a template parameter 'size_t SIZE'. In each
type that derives from one of these classes, it is now statically checked that
the range of each Genode::Register::Register- and
Genode::Register_set::Register_array-deriving sub-type is within [0..SIZE).

That said, SIZE is the minimum size of the memory region provided to the above
mentioned Mmio classes in order to avoid page faults or memory corruption when
accessing the registers and register arrays declared inside.

Note, that the range end of a register array is not the end of the last item
but the end of integer access that is used for accessing the last bit in the
last item.

The constructors of Genode::Mmio, Genode::Attached_mmio, and
Platform::Device::Mmio now receive an argument 'Byte_range_ptr range' that is
expected to be the range of the backing memory region. In each type that derives
from on of these classes, it is now dynamically checked that 'range.num_bytes
>= SIZE', thereby implementing the above mention protection against page faults
and memory corruption.

The rest of the commit adapts the code throughout the Genode Labs repositories
regarding the changes. Note that for that code inside Core, the commits mostly
uses a simplified approach by constructing MMIO objects with range
[base..base+SIZE) and not with a mapping- or specification-related range size.
This should be fixed in the future.

Furthermore, there are types that derive from an MMIO class but don't declare
any registers or register arrays (especially with Platform::Device::Mmio). In
this case SIZE is set to 0. This way, the parameters must be actively corrected
by someone who later wants to add registers or register arrays, plus the places
can be easily found by grep'ing for Mmio<0>.

1b4f7ae0d3 lx_emul: generate initcalls during build
Functions registered with 'module_init' (i.e., '__define_initcalls'),
'OF_DECLARE', and 'DECLARE_PCI_FIXUP_CLASS_FINAL' used to be static
constructors and had be explicitly registered using
'exec_static_constructors' before executing any Linux code.

With this commit we remove the constructor attributes from these
functions and create a global function pointer in the form of

__initptr_<name>_<id>_<counter>_<line number of macro>

'import-lx_emul_common.inc' will collect these '__initptr' symbols after
the compile step and generate a 'lx_emul_register_initcalls' function
that executes the functions pointed to. This step is now automatically
performed in 'lx_emul_start_kernel'. This way a call to
'exec_static_constructors' can be omitted in case there are no other
constructors in place.

4a2319a4d6 os: limit backtrace to stack of current thread
The frame-pointer-based backtrace does not work without enabling
-fno-omit-frame-pointer explicitly and in most cases leads to page
faults because non-pointer stack values are dereferenced during the
walk. The best we can do is to limit the backtrace walk to the stack of
the current thread to prevent page faults unrelated to the system state
without the use of the backtrace utility.

This commit introduces a printable Backtrace class usable in
Genode::log(), Genode::trace(), etc. The class is based on the new
function for_each_return_address(auto const &fn) that walks the stack in
its limits and calls fn() for each discovered return address on the
stack in the new os/include/os/backtrace.h. Archtecture-specific
stack-pointer retrieval and walk loops are implemented in dedicated
os/include/spec/<arch>/os/for_each_return_address.h files. Also, the
well-known Genode::backtrace() function (which logs the return-address
values) is provided for backwards compatibility.

68ac1347b9 lxip: configure thash/uhash entries to 2048
The number of hash entries for TCP/UDP corresponds to the number of
sockets managed by the stack. In case there are more sockets than
entries available, buckets will be created to compensate for the lack of
space. The default values for TCP (524288) and UDP (65536) are meant for
the in kernel that manages all sockets of the user land and leads
to very large hash table allocations (>20MB) during initialization.

Since on Genode a component has its own instance of the IP stack or uses
the VFS server, we do not need these kind of large default settings.

1e7116fcc1 lx_emul: manage page structs per buffer range
The management of Linux page structs is now tied to the life time of DMA
buffers. Thus, page structs are created when a buffer is allocated and
deallocated only when a buffer is freed - not on lx_emul_mem_free()
because DMA buffers are cached. Page struct refcounting was entirely
reworked in lx_emul/shadow/mm/page_alloc.c.

342e48115e lx_emul: replace USB devio API usage
The devio API in the Linux kernel promised to be a stable layer for our
USB host controller drivers, but the additional bookkeeping and dynamic

Therefore, we go a step back and process DMA transactions directly in and
out of the packet stream from the clients.

9f8ccc030b linux.port: add usb_net_cdc_ncm.patch
NCM tries to batch TX packets using timeouts (500us) and does not send packets
before 3 packets are in the submit queue. Timeouts take milliseconds on
dde_linux which leads to delayed ACKs and poor performance for the RX case.
Therefore, we send small packets (<100 Bytes) immediately without batching (it
might be an ACK or last packet of a larger transfer).

* During a device release, URBs discards, and reset operation the Linux task

e18c02991e lx_kit: use central signal handler for scheduling
This commit extends the Lx_kit initialization function by passing in
a signal handler that is used to perform the normally occurring
scheduler execution and is a follow-up change for the decoupling
scheduler execution commit.

Instead of burying the signal handler in the 'Lx_kit::Scheduler'
object it is provided by the main object where the driver is free
to perform any additional step before or after executing the scheduler.

dd1b8a106f drivers/wifi: perform multi-staged construction
Since the wireless LAN driver is actually a 'Libc::Component' due to
its incorporation of the 'wpa_spplicant' application, we have to
intercept its construction because we have to initialize the Lx_kit
environment before any static ctors are executed. Most Linux initcalls
are implemented as ctors that will be otherwise implicitly executed
before the controll is given to us in 'Libc::Component::construct'.

1cac134030 lx_kit: support multiple pending IRQs

caac994da8 lx_kit: decouple schedule execution
Prior to this commit, whenever an external event occurred, for example
timer or interrupt, the corresponding I/O signal handler was triggered.
This handler unblocked the task waiting for the event and initiated the
immediate execution of all unblocked tasks. Since these tasks may hit
serialization points, e.g. synchronously waiting for packet stream
operations, that require handling of other I/O signals this leads to
nested execution. This, however, is not supported and mixes application
and I/O level signal handling.

The flagging of the scheduling intent is now decoupled from its
execution by using an application level signal handler that is run in
the context of the components main entrypoint. The I/O signal handler
now triggers the scheduling execution by sending a local signal to
the EP.

Since it might be necessary to execute a pending schedule from the EP
directly the scheduler is extended with the 'execute' member function
that performs the check that the scheduler is called from within the
EP and triggers the execution afterwards.

dc178e0ab2 dde_linux: enhance KBUILD_MODNAME generation
It turns out solely relying on the name of the compilation-unit
is not enough. In at least one multi-device driver, e.g. rtlwifi,
an equally called compilation-unit is found in several different
directories. There KBUILD_MODNAME is used to name the driver,
which fails later on as the driver framework refuses to register
an equally named driver twice.

Instead of only considering the name of the compilation-unit also
include the last element of the path to generate differentiating
KBUILD_MODNAME value.

d5710d9de3 Move 'wifi' driver to dde_linux repository
The bulk of the driver code now lives in the 'dde_linux' repository,
which is available on all platforms, from where it can be referenced by
other repositories.

The 'wifi_drv' binary was delegated to a generic harness that includes
all configuration and management functionality shared by all wireless
device driver components, e.g., the wpa_supplicant. The code of the
device driver emulation environment is located in 'src/lib/wifi'. It
is referenced by the platform-specific driver library that resides in
the corresponding platform repository. The runtime configuration needs
to point the driver to proper driver library.

The platform-specific library is in charge of orchestrating the contrib
source utilized by the driver as well as providing the 'source.list'
and 'dep.list' files. It must include the generic library snippet
'repos/dde_linux/lib/wifi.inc' that deals with managing the emulation
environment code.

The 'repos/dde_linux/src/drivers/wifi/README' file contains more
detailed information on how to deploy the driver.
