4e714d3f3a base: handle cap depletion during session upgrade
When the own cap quota of a client does not suffice for a cap upgrade of
an existing session to a server, the client must issue a cap-resource
request to the parent. This logic was already in place for RAM quota but
was missing for cap quota.

9c9302e51d ldso: allow symbol resolution during dl_itera_phdr
When callback functions of `dl_iterate_phdr` required further jump slot
relocations this lead to a deadlock. Therefore, we allow the resolution
of further symbols from callback functions, but protect the ELF object
list during the iteration, which blocks any dynamic loading (e.g.,
dlopen/dlcose) of shared object by other threads while in program header
iteration.

Apparently the skewed motion timings came from the issue fixed by
"timer: restore semantics of periodic timeout 0". With the current

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.

3ed8df9089 x86/platform_drv: add Platform::Session::dma_addr
This patch adds the designated alternative to Dataspace::phys_addr to

still calls Dataspace::phys_addr but it should eventuelly become the
only caller before we can abolish this function.

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.

f925fef17b base: Refine Range_allocator::alloc_aligned
This patch changes the 'alloc_aligned' interface as follows:

- The former 'from' and 'to' arguments are replaced by a single
  'range' argument.

- The distinction of the use cases of regular allocations vs.
  address-constrained allocations is now overed by a dedicated
  overload instead of relying on a default argument.

- The 'align' argument has been changed from 'int' to 'unsigned'
  to be better compatible with 'addr_t' and 'size_t'.

698f6eb86c gdb_monitor: weaken reliance on sandbox internals
GDB monitor re-uses internal parts of the sandbox library. It thereby
relies on the internal detail of how local headers are included (using
"" instead of the now usual practice <>). A seemingly unrelated change
"init/sandbox: avoid repetitive state reports" eventually broke the
build of the GDB monitor.

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

It also fixes a few warnings caused by the double definition of
__GENODE__ (adding an missing include guard and making the #define
conditional).

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.

96cc660f95 sculpt: system reset via PS/2 and ACPI
This patch enables sculpt to utilize the CPU reset mechanism via the
PS/2 controller as well as the information provided via the ACPI FADT
information. Whenever the /config/system file is changed to <system
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.

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.

This patch adds session-routing options to connect components to the

8ecc258d3f sculpt: introduce runtime priorities
This patch adds 4 priority levels to the runtime subsystem. The highest
priority is used for components that are critical for the operation of
Sculpt, in particular the Leitzentrale GUI. All regularly deployed
components are assigned the lowest priority by default.

With priorities available in the runtime subsystem, this patch flattens
the priority levels at the top-level init to only two levels and
overlays the priority bands of the drivers, leitzentrale, and runtime
subsystems into one priority band. This has three benenfits:

- This change prevents the starvation of the Leitzentrale GUI from a
  spinning high-priority driver (issue #3997).

- The change will also ease the hosting of latency-critical components
  in the runtime subsystem that are prioritized higher than regular
  components, the storage stack, and the network stack.

- The Leitzentrale GUI remains always perfectly responsive regardless
  of the workloads deployed from packages. In the previous version,
  the runtime graph was sometimes stuttering on high system load.

9093c293cb sandbox: destroy 'Session_state' of local services
This patch adds the missing destruction of session-state objects of
local services when closing a session. Because of the missing
destruction, those session-state object remained part of the server
ID space. This becomes a problem once the backing store of the session
state object vanishes, that is when the client child gets removed from
the sandbox. Hence, the removal of a child with an open session to a
local service would lead to the corruption of the server ID space.

This patch adds the missing session.destroy() call.

935bb36fe4 base: fix child destruction while close requested
This patch fixes a corner case where a child is destructed while a
asynchronous close request to a sibling server is still pending.

The child immediately discarded the session ID as the end of the
close-session processing, assuming that this ID is never to be needed
again. The session-state continues to exist to handle asynchrous close
protocol with the server.

However, if the child is destructed at this point (before the server
responded to the session request), the destruction of the child would
not cover the discharging of the session state because the session state
was no longer be part of the client's ID space. So once the asynchronous
close response from the server came in, the session state contained
stale information, in particular a stale closed_callback pointer.

The patch fixes the problem by deferring the discarding of the client ID
to the point where the session state is actually destructed. So the
session of a pending close response is covered by the child destructor.

Thanks to Pirmin Duss for reporting this issue along with a test
scenario for reproducing it!

6223ae4413 riscv: Interrupt controller support
- Enable the "platform-level interrupt controller" PLIC on base-hw
- The RISC-V specification offers only a register description, but no
  layout for the register set. This implies the layout is platform
  dependent, and therefore, implemented separately for Qemu

366fda0e47 sculpt: release part_block after device discovery
This patch triggers the immediate removal of part_block once the
discovery of a fresh inserted USB stick has completed. Without the
patch, part_block was retained until the runtime was reconfigured the
next time for other reasons (e.g., toggling an inspect view). Until the
next reconfituration, part_block tended to stand in the way of directly
assigning the USB device to a VM.

2ff252360d sculpt: avoid flickering of leitzentrale
This patch increases the RAM quota of the nitpicker instance for the
leitzentrale to make it suffice for the buffering of content during
resize operations. This fixes a flickering artifact when having an
inspect view open while entering a WLAN passphrase. When the connect
button appears or disappears (depending on the number of written
characters), some parts of the inspect terminal would flicker sometimes.

c0a7565c21 os: shim helper for safe routing of env sessions
This shim component can be used in case where env sessions of child
(i.e., child's PD session) must be routed to another child of init.

Without the shim, init would directly need to interact with these
sessions and would thereby make itself dependent of the server's
behavior. RPC calls to a server hosted as a child lead to all kinds of
problems such as livelock situations, and putting the robustness of init
at the whim of its child.

With the shim, init merely needs to bootstrap the shim component by
routing the shim's env sessions to core as usual. The server is only
used for the sessions for the actual application hosted atop the shim.
