0ce79f3a8a udp: rename method calc_checksum update_checksum
In other contexts (IPv4) 'calc_checksum' merely returns a new checksum that is
then installed via 'checksum'. Thus, the UDP 'calc_checksum' that calculates AND
installs a new checksum is misleading.

dbbda9839b lwip: enhance http_srv_static and http_clnt
Both, client and server now read their IP config from their Genode config.
Furthermore, the client now waits 4 instead of 2 seconds before sending the
first request to prevent connection fails in tests with a slow startup. The
client truncates its packet dump for better readability.

fac69eff48 core: handle out-of-memory in RM service
This patch adds the missing exception handling for depleted RM session
quotas. If core runs out of session quota while creating a new region
map, it now reflects this condition as a Region_map::Out_of_metadata
exception to the RM client. Thanks to Denis Huber for reporting the
issue!

8d1cf08b1a core: fix regression in dataspace ownership test
This patch revives our ds_ownership test from 2012, which just revealed
a regression in core where the dataspace-free operation of the RAM
service would unconditionally destroy dataspace objects from foreign
sessions. The patch fixes the bug and adds an updated version of the
test to the autopilot.

17c79a9e23 base: avoid use of deprecated base/printf.h
Besides adapting the components to the use of base/log.h, the patch
cleans up a few base headers, i.e., it removes unused includes from
root/component.h, specifically base/heap.h and
ram_session/ram_session.h. Hence, components that relied on the implicit
inclusion of those headers have to manually include those headers now.

While adjusting the log messages, I repeatedly stumbled over the problem
that printing char * arguments is ambiguous. It is unclear whether to
print the argument as pointer or null-terminated string. To overcome
this problem, the patch introduces a new type 'Cstring' that allows the
caller to express that the argument should be handled as null-terminated
string. As a nice side effect, with this type in place, the optional len
argument of the 'String' class could be removed. Instead of supplying a
pair of (char const *, size_t), the constructor accepts a 'Cstring'.
This, in turn, clears the way let the 'String' constructor use the new
output mechanism to assemble a string from multiple arguments (and
thereby getting rid of snprintf within Genode in the near future).

To enforce the explicit resolution of the char * ambiguity, the 'char *'
overload of the 'print' function is marked as deleted.

84ee970e9b run: look for platform boot string at beginning of line
When running the same kernel in a VM as on the host system and the
kernel boot message from the VM appears on the log output, the run tool
assumes that the host machine has rebooted unexpectedly. With this
commit, an unexpected reboot is assumed only if the kernel boot message
appears at the beginning of a line. On base-hw, we enforce a line feed
at the beginning of the boot message as the SPIKE emulator log starts
with the first message of the kernel lacking a line feed.

Conveying the ROM filename as the final label element simplifies

Annotations by nfeske:

This commit also changes the ROM session to use base/log.h instead of
base/printf.h, which produced build error of VirtualBox because the
vbox headers have a '#define Log', which collides with the content of
base/log.h. Hence, this commit has to take precautions to resolve this
conflict.

The commit alse refines the previous session-label change by adding a
new 'Session_label::prefix' method and removing the use of 'char const *'
from this part of the API.

88b358c5ef Unification of native_capability.h
This patch establishes the sole use of generic headers across all
kernels. The common 'native_capability.h' is based on the version of
base-sel4. All traditional L4 kernels and Linux use the same
implementation of the capability-lifetime management. On base-hw, NOVA,
Fiasco.OC, and seL4, custom implementations (based on their original
mechanisms) are used, with the potential to unify them further in the
future.

This change achieves binary compatibility of dynamically linked programs
across all kernels.

Furthermore, the patch introduces a Native_capability::print method,
which allows the easy output of the kernel-specific capability
representation using the base/log.h API.

d71f0a9606 Cleanup of parent-cap handling
This patch alleviates the need for a Native_capability::Dst at the API
level. The former use case of this type as argument to
Deprecated_env::reinit uses the opaque Native_capability::Raw type
instead. The 'Raw' type contains the portion of the capability that is
transferred as-is when delegating the capability (i.e., when installing
the parent capability into a new component, or when installing a new
parent capability into a new forked Noux process). This information can
be retrieved via the new Native_capability::raw method.

Furthermore, this patch moves the functions for retriving the parent
capability to base/internal/parent_cap.h, which is meant to be
implemented in platform-specific ways. It replaces the former set of
startup/internal/_main_parent_cap.h headers.

e3fbeeb25e vbox: Implement hwaccl support for Muen
* Implement VMMR0_DO_VMMR0_INIT operation for Muen

   - Indicate VT-x support
   - Enable unrestricted guest mode
   - Set CR[0|4] mask to enable masking of guest CR0.[NE,NW,CD] and
     CR4.VMXE bits.

 * Implement VMMR0_DO_GVMM_CREATE_VM on Muen

   Return error if trying to create SMP VM as VMs with multiple CPUs are
   currently not supported on hw_x86_64_muen.

 * Add Muen-specific Mem_region type

   On hw_x86_64_muen the guest memory layout is static, thus regions are
   handed out from an array of memory regions.

   Use sinfo API to calculate the base address of the VM RAM physical
   0x0 region. This allows to dynamically modify the VM RAM size by
   adjusting the Muen policy and Genode vbox files accordingly.

   Zeroize all memory regions apart from VM Ram since Virtualbox expects
   these regions to be cleared.

 * Add Muen subject state struct

   The subject state encompasses the guest VM machine state that is
   transfered between Virtualbox and hardware accelerated execution on
   Muen.

 * Add Muen-specific Vm_handler class
 * Use Vm_handler to run VM
 * Instruct recompiler to flush its code cache
 * Copy the Muen subject state to/from the Vbox PCPUMCTX.
 * Use the VM interruptibility state to inform the recompiler whether
   interrupts are currently inhibited.
 * Explicitly handle control register access

   If a VM-exit occurs due to a control register access, handle it and
   directly continue hardware accelerated execution of guest VM.

   Note: On NOVA control register accesses are handled by the kernel [1].

   [1] - https://github.com/alex-ab/NOVA/blob/master/src/ec_vmx.cpp#L106

 * Reset guest interruptibility state

   Assert that interrupts are not inhibited in the Virtualbox machine
   state and clear Blocking-by-[STI|MOV to SS] guest interruptibility
   flags prior to running a guest VM in hwaccel mode.

 * Set return code depending on exit reason

   Do not unconditionally emulate the next instruction on VM exit. This
   makes sharing the VM FPU state with Virtualbox unnecessary, as FPU
   instructions are not emulated by the recompiler any longer.
   Also, assert that the FPU has not been used by the recompiler

 * Inject pending guest VM interrupts on Muen

   Use mapped subject pending interrupts page of guest VM to perform
   interrupt injection. IRQs are transferred from the Virtualbox trap
   manager state to the pending interrupts region for injection. If an
   IRQ remains pending upon returning to the recompiler, it is copied
   back to the trap manager state and cleared in the subject interrupts
   region.

 * Inform recompiler about changed SYSENTER_[CS|EIP|ESP] values,
   otherwise values set while running the guest VM hardware accelerated
   may get lost.

 * Implement genode_cpu_hz() on Muen

   Determine the CPU frequency dynamically using the sinfo API.

558cc8e00c intel_fb_drv: make buffering mandatory
Instead of providing a buffer to the client and blitting from that
to the "real" framebuffer as an option, with this commit we always do so.
Thereby its possible to immediately destroy the old framebuffer used by
hardware when a configuration change is done, and a new framebuffer
is used. This also simplifies the modesetting.
Moreover, this commit fixes an issue when not using the connector reporting.
Until now the initial mode detection of connectors was only done when
the report was created. this is a regression that entered the driver
when upgrading to the recent Linux kernel version.

ebdb1c6892 sel4: reduce initial memory demand of PD session
This is a follow-up commit to "slab: throw exception if initial
allocation fails". It is needed because on seL4, the PD session quota is
used as backing store for the meta data of the PD's virtual memory. For
this reason, PD sessions on seL4 require more session quota compared to
the other kernels. Apparently, the default quota is too scarce to
complete the PD-session construction. By shrinking the number of
supported page-table entries, we reduce the size of the PD session
component so that the creation succeeds.

1208d14681 hw: use kernel timer for timer driver
* Adds public timeout syscalls to kernel API
  * Kernel::timeout installs a timeout and binds a signal context to it that
    shall trigger once the timeout expired
  * With Kernel::timeout_max_us, one can get the maximum installable timeout
  * Kernel::timeout_age_us returns the time that has passed since the
    calling threads last timeout installation

* Removes all device specific back-ends for the base-hw timer driver and
  implements a generic back-end taht uses the kernel timeout API

* Adds assertions about the kernel timer frequency that originate from the
  requirements of the the kernel timeout API and adjusts all timers
  accordingly by using the their internal dividers

* Introduces the Kernel::Clock class. As member of each Kernel::Cpu object
  it combines the management of the timer of the CPU with a timeout scheduler.
  Not only the timeout API uses the timeout scheduler but also the CPUs job
  scheduler for installing scheduling timeouts.

* Introduces the Kernel::time_t type for timer tic values and values inherited
  from timer tics (like microseconds).
