db97af8dec vfs: fix read of large files in fs_file_systems
For fs_file_systems, reads are limited to the size of the packets from the
File_system session. Hence, we cannot read the large files in one go.

This fix is particularly helpful for fonts_fs, as it enables including font
files from a File_system.

813f4d976b lxip: allocate skb with properly aligned IP header
Comment in Linux sources:

  Since an ethernet header is 14 bytes network drivers often end up with
  the IP header at an unaligned offset. The IP header can be aligned by
  shifting the start of the packet by 2 bytes. Drivers should do this
  with:

  skb_reserve(skb, NET_IP_ALIGN);

This is ensured when using netdev_alloc_skb_ip_align().

a24224ffc3 usb_host: improve isochronous performance on Intel
This patch takes advantage of block transfer interrupts on Intel XHCI
controllers which is used during isochronous transfers. Because of a bug
in hardware (see usb_host_isoc_bei.patch header), this feature has been
disabled for Intel leading to up to 8000 interrupts/s for isochronous
transfer causing severe CPU consumption on Genode. With this commit we
lower host driver consumption to normal levels.

a4115cfea9 base-linux: discharge timestamp on AARCH64
The kernel-agnostic 'Trace::timestamp' function for arm_64 executes the
'mrs %0, pmccntr_el0' instruction, which is not permitted for user-level
programs on Linux. This patch shadows the generic timestamp.h header
with dummy that returns zero. This return value prompts the timeout
framework to disable the interpolation of time based on timestamps. This
avoid the illegal-instruction abort but comes with two llimitations:

First, time measurements are effectlively limited to a granulariry of 1
millisecond (deliberately constrained by the timer driver).

The quirk is applied when using the base-linux API. Should a generic
application (that uses the base API only) call 'Trace::timestamp'
directly, the illegal instruction is executed.

2f9d430c00 base-linux: 64-bit ARM support
This patch adds support for running Genode/Linux on the AARCH64
architecture.

- The kernel-agnostic startup code (crt0) had to be extended to
  capture the initial stack pointer, which the Linux kernel uses
  to pass the process environment. This is in line with the
  existing startup code for x86_32 and x86_64.

- The link order of the host libraries linked to lx_hybrid
  programs had to be adjusted such that libgcc appears at last
  because the other libraries depend on symbols provided by
  libgcc.

- When using AARCH64 Linux as host, one can execute run scripts
  via 'make run/<script> KERNEL=linux BOARD=linux' now.

fdb1a4dd88 base-linux: avoid legacy syscalls
Until now, Genode's Linux system call bindings were based on original
Unix system calls that were later superseded by more flexibile variants.
E.g., 'openat' is a modern version of 'open'. Even though Linux upholds
the compatiblity with the original versions for existing architectures
like x86, the legacy syscalls are absent for the recently added AARCH64
architecture. A good overview of the system calls accross the prominent
architectures can be found at

https://chromium.googlesource.com/chromiumos/docs/+/master/constants/syscalls.md

This patch updates Genode's syscall bindings to avoid legacy versions,
thereby easing the support for AARCH64. The used "modern" versions
were introduced back in Linux version 2 days. So we are fine to rely
on them.

The patch slightly changes the signature for lx_stat because this system
call is merely used to check for the existance of a file and its size.
The new name 'lx_stat_size' draws a closer connection to its use case.
That said, the stat syscall has not been updated to the modern statx
since statx is still a fairly recent addition.

d477062c56 base-linux: simplify clone syscall binding
This patch simplifies the use of the clone system call for creating
processes and threads. Until now, the binding used an opaque pointer
argument to pass context information to the newly created process or
thread. However, upon close inspection, this is not a strict
requirement.

A newly created thread accesses its contextual information by
using its stack pointer as key. The pointer argument is not used.

The creation of processes is strictly serialized because the
intermediate stack used in-between clone and execve is a global
variable. Since we rely on the serialization anyway, we can pass the
context information of a new process via a global variable as well.

This change simplifies the syscall binding for the upcoming AARCH64
support, which would otherwise require us to deal with the notion
of TLS on Linux.

49184fb938 net: circumvent stringop-overflow error
With the update to GCC 10, the compiler stopped with an error when compiling
places where a MAC address is copied from outside into a packed object using
the Net::Netaddress::copy method (e.g. in
Net::Arp_packet::dst_mac(Mac_address)):

! error: writing 6 bytes into a region of size 4 [-Werror=stringop-overflow=]

While trying to find a clean solution for this error, I found posts on
gcc.gnu.org and github that stated that the size calculations that cause these
errors are incorrect. Indeed, I could verify that the actual size of the two
regions was static and exactly the same in places were the error occured.

Furthermore, I couldn't find a way of making it more clear to the compiler
that the sizes are the same. By accident, we found that using the address of
the first element of the array that forms the second region instead of the
array address itself, somehow circumvents the error.

52e8c95321 net: fix packed-conversion compiler warning
With the update to GCC 10 the compiler used to warn when using the internet
checksum functions on packet classes (like in
Net::Ipv4_packet::update_checksum):

warning: converting a packed ‘Net::[PACKET_CLASS]’ pointer
         (alignment 1) to a ‘const uint16_t’ {aka ‘const short
         unsigned int’} pointer (alignment 2) may result in an
         unaligned pointer value

Apparently, the 'packed' attribute normally used on packet classes sets the
alignment of the packet class to 1. However, for the purpose of the
internet-checksum functions, we can assume that the packet data has no
alignment. This is expressed by casting the packet-object pointer to a pointer
of the new packed helper struct 'Packed_uint16' that contains only a single
uint16_t member before handing it over to the checksum function (instead of
casting it to a uint16_t pointer).

4e822436fc nic_router: use increasing src port for new nat
The NAT feature of the NIC router used to prefer re-using source ports that
have been freed recently. From an external server's perspective, if a client
dies and restarts, chances are high that the new connect arrives with the same
source-IP/source-port as the old connection. The server has to forcefully reset
the connection. If that happens a lot, the server may even start to ignore
further connections from this IP/port combination for a while as a mitigation.

This patch adds a continuous counter feature that makes sure that every new
port allocation will increment and result in a port that hasn't been used for a
long time.

The NAT feature of the nic_router is now more in line with RFC 6056 chapter 4.

handled by the EP thread, which however is blocking on the write buffer mutex.

The commit uses two write buffers, one which is filled by the EP and a second
which is used by pthread.0. The two buffers are swapped protected by a mutex

This state is necessary to maintain a valid cursor position at all

9cb8c37e3a terminal: fix sporadic freeze on font-size changes
The direct execution of application-level code by a watch handler is
troublesome because those handlers are executed at the I/O signal level.
In the concrete case, the watch handler got recursively called because
the handler called _handle_config (application-code), which called the
VFS, which in turn performed a wait_and_dispatch_one_io_signal, which
again invoked the watch handler.

The patch works around the problem by letting the watch notification
trigger the application-level signal for the _config_handler.

d73eaaa14c libc: exclude arm_initfini.c
This compilation unit contains a global constructor, which violates our
assumption that the libc is free of global constructors on ARMv7.
Specifically, the graphical terminal fails with the following message:

[init -> terminal] Error: Component::construct() returned without executing
                          pending static constructors (fix by calling
                          Genode::Env::exec_static_constructors())
[init -> terminal] Error: Uncaught exception of type 'Linker::Fatal'

In this case, the libc-less terminal uses the VFS. The VFS mounts the
ttf VFS plugin. The ttf VFS plugin depends on the libc.

The compilation unit 'arm_initfini.c' can safely be excluded because it
merely initializes the global '_libc_arm_fpu_present' variable, which
is not used by the current version of our libc/libm.

dc8c899c1d Streamline platform-device API on ARM
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of

- Platform::Device       - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq  - interface for receiving device interrupts

The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.

When we allowed symbol resolution during exceptions, we used the shared
object lock to protect ELF object list manipulation (e.g., dlopen,
dclose) when executing exception unwinding code in the linker.
Unfortunately, sometimes libraries that are loaded by 'dlopen' may raise
exceptions in the process, leading to a deadlock within the unwind code.
In order to resolve this, we now protect the object list operations
(i.e., enqueue, removal, iteration) by a separate mutex. This allows
the shared object interface to throw exceptions.

0339318572 platform_session: cache arg for alloc_dma_buffer
This patch extends the 'Platform_session::alloc_dma_buffer' interface
with a 'Cache' argument that corresponds to the argument accepted by
'Ram_allocator::alloc', which is used by the platform driver under the
hood.

Since the x86 platform driver used to be hardwired to allocate DMA
buffers as UNCACHED, I adjusted all drivers by specifying the UNCACHED
argument. Right now, this is needed as a hint for core to steer the
allocation of I/O page tables. Once we eliminate the need for such hints
(by introducing an explicit 'Region_map::attach_dma' operation), we can
revisit the drivers individually because cached DMA buffers should
generally be fine on the x86 architecture.

b661459aca sandbox/init: parse config using 'List_model'
This commit replaces the hand-crafted config processing by the use of
the 'List_model' utility. This has the following advantages:

- The parsing follows a common formalism that makes the code
  easier to maintain and to understand. Several parts of the code
  had to be changed (for the better) to make it fit the list model
  approach. E.g., the child states have become more expressive
  and logical.

- In the common case, the XML data is traversed only once, which
  increases the parsing speed in dynamic scenarios.

- The code becomes easier to optimize. In particular, the patch skips
  the re-evaluation of the session routing if no service is affected
  by the config change.

The patch also revisits the init test by removing overly long sleep
phases and extending a few sleep phases that were too short when
executing the test on Qemu.

GDB monitor re-uses internal parts of the sandbox library. It thereby

This patch makes the GDB monitor less reliant on the way of how the
sandbox includes headers internally.

49481dd3fb timer: restore semantics of periodic timeout 0
The 'Timer::Session::trigger_periodic' RPC function used to accept 0 as
a way to de-schedule the periodic processing. Several components such as
nitpicker relied on this special case. In "timeout: rework timeout
framework", the value of zero was silently clamped to 1, which has the
opposite effect: triggering signals at the maximum rate. This results in
a visible effect in Sculpt where the leitzentrale-nitpicker instance
produces a constant load of 2% CPU time.

This patch restores the original timer semantics by

- Documenting it in timer_session.h,

- Handling the case explicitly in the timer implementation, and

- Replacing the silent clamping of the unexpected value 0 passed
  to the timeout framework by a diagnostic error message.

state="reset"/>, both mechanisms are triggered.

Supporting both mechanisms is useful because the PS/2-based reset does
not work reliably on modern machines. The PS/2-based reset is useful in
the case when the FADT reset information refers to the PS/2 command
port. In this case, the platform driver is unable to access this port
because it is already handed out to the PS/2 driver. In this case, the
PS/2 driver kicks in.

2c7c7767fc platform_drv: respond to <system state="reset"/>
If 'system="yes"' is specified in the <config>, the platform driver now
monitors the content of the system ROM. Should the value become "reset",
a reset is triggered using information obtained from the ACPI driver.

fb9f6812e1 acpi_drv: export ACPI reset info from FADT
The change of the platform driver is needed to avoid a parsing error of
the ACPI ROM when encountering an unexpected <reset> node.

Thanks to Alexander Boettcher for the preventing the regression of #3829
and improving the adherence to the ACPI spec when parsing the reset type.

27527bf165 wm: allow clients to upgrade session caps
This patch adds the handling neccessary for clients to upgrade the cap
quota of their GUI session. Until now, the upgrade mechanism supported
only RAM quota.

The limitation became visible once a client - in the particular case the
motif_decorator - attempted the cap upgrade of its GUI session. The cap
quota would arrive at the wm, but the wm would keep it instead of
forwarding the quota to nitpicker. This resulted in an infinite retry
loop at the motif_decorator, ultimatedly depleting all its cap quota.

f839b3ecba wm: make hover handling robust against input races
The window manager infers the overall state from the intercepted input
events for the decorator and all GUI clients. However, each of those
parties have an independent input-event stream. Whereas the order of
events within one GUI session is strict, the order of events between GUI
sessions is arbitrary. The window manager wrongly relied on a global
event ordering to track the pointed-at GUI session.

The patch removes the assumption of a global event order by tracking the
relevant pointer state for each GUI session independently and evaluating
these states when propagating the pointer position to the decorator.

ca5522d4d9 sculpt: move chargen files to config/keyboard/
The addition of further keyboard layouts would otherwise pollute the
config/ directory too much.

Caution: When updating Sculpt OS, don't reuse your existing
config/event_filter file unmodified! You need to replace the chargen
includes, pointing to the new location, e.g.,

  <include rom="en_us.chargen"/>
  <include rom="special.chargen"/>

must be changed to

  <include rom="keyboard/en_us"/>
  <include rom="keyboard/special"/>

8f1db47c26 sculpt: screen capturing and event injection
This patch adds session-routing options to connect components to the
capture/event interfaces of the global nitpicker GUI server or the
leitzentrale GUI server. It thereby enables the implementation of screen
capturing components, remote management tools, or virtual keyboards.

Since those services are very powerful, they are subsumed under the
"hardware" category of the component graph as opposed to the GUI
category, which guarantees the separation of clients.
