84bbde2879 nic_router: fix interface-local quota reporting
The router used to ignore the value of the <report quota=".."/> attribute when
it came to determining whether an interface's report is empty or not.
Therefore, merely configuring <report quota="yes"/> didn't cause interfaces
(and their quota) to show up in the report. Instead, interface quota was
reported as side effect of <report stats="yes"/>. The commit fixes this
inconsistency with the README.

09b3fa389d nic_router: destroy timed out ARP waiters
The only object that is dynamically allocated by a network interface and that
was not equipped with a self-destruct timeout was the ARP waiter. This commit
closes this gap by adding a timeout to each ARP waiter that is set to 10
seconds by default but can be configured via the new <config> attribute
'arp_request_timeout_sec'.

20371d0445 nic_router: drop closed tcp links immediately
RFCs recommend to keep TCP connections for a certain time even after they
finished a close handshake, AFAIK, in order to be able to recognize astray
packets when they arrive later. This seems overambitious especially when in
the context of the router where session quota is pretty limited. Therefore,
this commit drops this final timeout and drops closed connections immediately.

58726a6707 nic_router: lower non-open tcp timeout to 30 sec
The previous value of 60 seconds was never observed in real-time scenarios and
UDP, for instance always used a timeout of 30 seconds without causing issues.
Note that this applies only to TCP connections in a state other than
ESTABLISHED, i.e., while it is still safe to early-drop the connection.

0a33168733 nic_router: mark tcp open only with full handshake
The TCP connection state "ESTABLISHED" (in the router "OPEN") is a privileged
one for peers because it lasts very long without any peer interaction (in the
NIC router it's only 10 minutes, but RFCs recommend not less than 2 hours and
4 minutes). Furthermore, TCP connections in this state are normally not
available for early-drop on resource exhaustion. This means that this state
binds resources to a connection potentially for a long time without the option
of regaining them under stress. Therefore, this state should be entered with
care.

Up to now, the router marked a TCP connection with this state as soon as it had
seen one matching packet in both directions, which is rather quick. However,
implementing a very precise tracking of the exact TCP states of both peers and
only marking the connection "ESTABLISHED" when both peers are "ESTABLISHED" is
a difficult task with lots of corner cases.

That said, this commit implements a compromise. The router now has two flags
for each peer of a TCP connection - FIN sent and FIN acked - and sets them
according to the observed TCP flags. The "ESTABLISHED" state is entered only
when FIN acked is set for both peers (without having observed an RST or FIN
flag meanwhile).

93c3f6371b nic_router: remove reference utilities
The Reference and Const_reference utility were introduced in order to express
that something is a reference (no null value) but can be changed dynamically
(not possible with built-in C++ references). However, the idea of preventing
every possibility for null pointer faults, with which the router was built
initially, has not prevailed and using pointers instead of the utility saves
logic and makes the code more readable to other C++ developers.

f7f171e457 nic_router: fix leak on domain deinit
The deinitialization method of Domain used to rely on Domain::with_dhcp_server
in order to dissolve and destroy a present DHCP server. However, this method
skipped calling its functor argument also when there was a DHCP server but an
invalid one. This commt replaces the with_dhcp_server with a pointer null-check
in order to fix the leak.

c96150bc70 nic_router: smarter emergency free on exhaustion
Re-implements an emergency freeing of resources on exhaustion of session quota.
In contrast to the past one, the new algorithm is executed directly where the
exhaustion occurs. Instead of interupting the packet handling and restart it
from the beginning after the freeing action, packet handling is now continued
at the point of exhaustion (if enough resources could be freed). Furthermore,
the new algorithm frees only 100 objects (instead of 1024) at a max as we found
this to better match real-life observations. And finally, the router now drops
ICMP first, then UDP, then TCP - as this better reflects priorities - and
refrains from dropping TCP connections in the ESTABLISHED state. If the router
cannot free a sufficient amount of resources, the packet that caused the
exhaustion is dropped with a warning (verbose_packet_drop="yes").

ac42ade48c nic_router: remove use of exception handling
Remove the use of C++ exception as much as possible from the router as C++
exception handling can be resource intensive and can make code hard to
understand.

This also removes the garbage collection that the router used to do when a
session ran out of quota. This is motivated by the fact that the garbage
collection was rather simple and removed connection states regardless of their
current state, thereby causing broken connections. The change is part of this
commit as the approach to integrating garbage collection relied strongly on
exception handling.

The user story behind removing garbage collection: The router emergency-dropped
an established TCP connection (with NAPT) and on the next matching packet
re-created it with a different NAPT port, thereby breaking the connection. With
this commit, existing connections are prioritized over new ones during resource
exhaustion and the packets that attempt to create a new connection in such a
state are dropped with a warning in the log (verbose_packet_drop="yes").

Note that the state resolves itself with time as existing connections time out
or are closed by peers.

bb06d879aa os: make 'Genode::Color' C++20 friendly
This patch turns 'Color' from a class to a POD type by replacing
the constructors by the named create functions 'rgb', 'clamped_rgb',
and 'clamped_rgba'. It thereby enables the initialization of Color
values using { .r = ... } syntax and makes the type usable in const
expressions.

It also narrows the type for color components and alpha values to
uint8_t. So possible integer overflows of computed values are detected
by -Wconversion.

As 'Color::rgb(0, 0, 0)' is repeatedly used as a default value, the
patch adds the 'Color::black()' function.

7ec08af6d9 usb: session renewal & new client API
Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.

The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.

The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.

This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.

The adaptations necessary target the following areas:

* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
  reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
  with the new policy rules of the USB host controller driver

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>.

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.

77b0e10e88 vfs/ram_file_system: deferred unlink
This patch changes the unlink operation of the ram fs to defer the
destruction of a file until it is no longer referenced by any VFS handle.
When unlinked, the file no longer appears in the directory. But it can
still be opened and accessed.

With this change, a parent process of a Unix-like subsystem becomes able
to pass the content of an unlinked file to a forked child process. This
mechanism is required when using the 'exec' command in Tcl scripts.

Another use case is the 'tmpfile()' function.

713659cea5 test-trace: adjust rate of top passing tracepoints
The traced top instance was configured to be active every two seconds
whereas the trace test uses a grace time of only 1.5 seconds before
raising the FOREIGN state of a trace subject as an error.

The state of a trace subject can change only whenever the traced thread
passes a trace point. Hence, with the original configuration, the
release of top as trace subject can take up to two seconds. The patch
reduces the rate to 0.5 seconds to satisfy the expectation of
test-trace.

bfe88307de core: filter trace subjects by TRACE session label
This patch changes core's TRACE service to expose trace subjects only if
their PD label matches the label of the TRACE monitor. Hence, by default,
a trace monitor can only observe itself and its child components. Only
if the trace monitor's parent rewrites the trace-session's label, the
view of trace monitor can become broader. For example, when rewriting
the trace label to an empty string "", the trace monitor becomes able to
observe the sibling components hosted in the same init instance as the
trace monitor.

To grant a trace session the special privilege of obtaining a global
system view (including the kernel's trace subjects), the top-level init
has to rewrite the session's label to an empty string. At core, this
specific label "init -> " is handled as a special case that discharges
the filtering/namespacing of trace subjects.

Note that the trace-subject label as reported as subject info is now
given relative to the label of the trace session. As a nice side effect
of this change, the pkg/test-trace_logger works now when executed by the
depot_autopilot as well as via the test.run script.

eefaa07024 base: add irq_type session argument
By adding the `irq_type` argument, one can explicitly specify whether to
use LEGACY, MSI or MSI-X interrupts. We formerly used the
`device_phys_config` to implicitly select MSI, however, with the
addition of IOMMU support to the platform driver there is at least one
instance where we need an MSI for a non-PCI device.

Yet, by adding another session argument to the Irq session, we exceed
the character limit for session args. Since not all arguments are
relevant for LEGACY interrupts resp. MSI, we can split the Irq_connection
constructor to handle the two cases separately and omit unneeded
arguments.
