66198660aa Noux: add noux_net_lighttpd.run
This patch adds lighttpd as noux package. However, we do not use the
original build system but rather compile lighttpd directly from the
Genode build system. This is needed because we want to statically link
lighttpd modules into the binary. This mode is (somehow) supported by
the SConscript that comes with lighttpd. However, the GNU build scripts
do not expose this feature.

228e70bb5f Native version of lighttpd
The port of lighttpd at 'ports/src/app/lighttpd' executes the web server
directly (w/o using Noux). It is accompanied by the lighttpd.run script.

At the current stage, lighttpd is starting up but fails because of an
unsupport fcntl call.

7a7adfbb63 Add mmap and nunmap to libc_noux, libc_fs
In the current form, only PROT_READ is supported. This case is emulated
by copying the file content into new allocated backing store. Even
though the performance benefits of mmap-using code will not be
preserved, code that relies on mmap can be executed via the libc_noux
or libc_fs plugins, i.e. lightttpd.

74b7b768f8 Noux: have bash use libc's 'getcwd()' function
The bash configure script cannot detect if the 'getcwd()' function in
Genode's libc works correctly, so it assumes that it is broken and makes
bash use its own version of this function. With this patch bash uses the
libc version, which has a Noux-specific implementation in the 'libc_noux'
plugin.

a7235d2411 NOVA: Use Genode interfaces to bootstrap Vancouver
Since no kernel objects can be created anymore outside Genode::core,
the Vancouver port must be adjusted to use solely the Genode interfaces.

The Vcpu_dispatcher creates all portals via the cpu_session interface and
uses the feature to setup a specific receive window during a IPC (the
cap_session::alloc IPC) to place to be received/to be mapped capability
(virtualization exception portal) at the designed indexes.

The actual vCPU thread extends from a normal Genode::Thread and extends it
by specific vCPU requirements, which are a larger exception base window and
the need by Vancouver to place the SM and EC cap at indexes next to each other.

ae6257dce1 Use NOVA microkernel from github, add 64bit
Use git to get recent kernels from github. Adjust NOVA patch to compile
with recent github version. Patch and use makefile of NOVA microkernel
to avoid duplicated (and outdated) makefile in Genode

Furthermore, this patch adds support for using NOVA on x86_64. The
generic part of the syscall bindings has been moved to
'base-nova/include/nova/syscall-generic.h'. The 32/64-bit specific
parts are located at 'base-nova/include/32bit/nova/syscalls.h' and
'base-nova/include/64bit/nova/syscalls.h' respectively.

On x86_64, the run environment boots qemu using the Pulsar boot loader
because GRUB legacy does not support booting 64bit ELF executables.

In addition to the NOVA-specific changes in base-nova, this patch
rectifies compile-time warnings or build errors in the 'ports' and
'libports' repositories that are related to NOVA x86_64 (i.e., Vancouver
builds for 32bit only and needed an adaptation to NOVAs changed
bindings)

288fd4e56e Add support for allocating DMA memory
This patch extends the RAM session interface with the ability to
allocate DMA buffers. The client specifies the type of RAM dataspace to
allocate via the new 'cached' argument of the 'Ram_session::alloc()'
function. By default, 'cached' is true, which correponds to the common
case and the original behavior. When setting 'cached' to 'false', core
takes the precautions needed to register the memory as uncached in the
page table of each process that has the dataspace attached.

Currently, the support for allocating DMA buffers is implemented for
Fiasco.OC only. On x86 platforms, it is generally not needed. But on
platforms with more relaxed cache coherence (such as ARM), user-level
device drivers should always use uncacheable memory for DMA transactions.

66290ea46d Stacked file systems for Noux
This patch introduces support for stacked file systems alongside new
glue for accessing file-system implementations provided via Genode's
new file-system-session interface.

Using stacked file systems, an arbitrary number of file systems (such
as tar archives or file systems implemented as separate Genode
components) can be composed to form one merged virtual file system.

An example is given via the 'ports/run/noux_bash.run' script. This run
script creates a virtual file system out of multiple tar archives each
containing the content of a particular GNU package. In addition, one
'ram_fs' is mounted, which enables Noux to perform write operations.
This way, the shell output can be redirected to a file, or files can
be saved in VIM.

9a00ad7ae3 Support for dynamic ROM sessions, fix #170
This patch introduces support for ROM sessions that update their
provided data during the lifetime of the session. The 'Rom_session'
interface had been extended with the new 'release()' and 'sigh()'
functions, which are needed to support the new protocol. All ROM
services have been updated to the new interface.

Furthermore, the patch changes the child policy of init
with regard to the handling of configuration files. The 'Init::Child'
used to always provide the ROM dataspace with the child's config file
via a locally implemented ROM service. However, for dynamic ROM
sessions, we need to establish a session to the real supplier of the ROM
data. This is achieved by using a new 'Child_policy_redirect_rom_file'
policy to handle the 'configfile' rather than handling the 'configfile'
case entirely within 'Child_config'.

To see the new facility in action, the new 'os/run/dynamic_config.run'
script provides a simple scenario. The config file of the test program
is provided by a service, which generates and updates the config data
at regular intervals.

In addition, new support has been added to let slaves use dynamic
reconfiguration. By using the new 'Child_policy_dynamic_rom_file', the
configuration of a slave can be changed dynamically at runtime via the
new 'configure()' function.

The config is provided as plain null-terminated string (instead of a
dataspace capability) because we need to buffer the config data anyway.
So there is no benefit of using a dataspace. For buffering configuration
data, a 'Ram_session' must be supplied. If no 'Ram_session' is specified
at construction time of a 'Slave_policy', no config is supplied to the
slave (which is still a common case).

An example for dynamically reconfiguring a slave is provided by
'os/run/dynamic_config_slave.run'.

fe2addf5b0 Noux: first functional version of fork
The resource virtualization layer has been extended to support sub RM
sessions because this feature is used by the dynamic linker. Currently,
the address space of the forking process is copied eagerly. However,
different dataspace types are treated differently. For example, only RAM
dataspaces are copied but no ROM dataspaces.

At the libc side, a setjmp/longjmp-based trampoline mechanism is used to
implement the continuation of the main thread inside the new process.
This procedure is also responsible for re-establishing the relationship
to the new process' parent as well as its Noux session.

This version is still in flux and has many rough edges. It is tied to
OKL4 for now.

this patch remedies this inconvenience.

5aaf04915c Intercept CPU session of Noux::Child
To implement fork semantics, we need to customize the bootstrapping of
the newly created process, in particular the startup of the main thread.
The CPU session interface provides a suitable hook. By virtualizing the
CPU connection of the process to core, we can defer (and parametrize)
the startup of the main thread. Furthermore, this enables us to detect
illegal attempts by the Noux process to create threads in addition to
the main thread.

652a4afd51 Intercept RAM and RM of Noux processes
By letting Noux processes talk to service implementations local to the
Noux server, we can track RAM allocations and RM operations. This is
needed as a prerequisite to implement fork.

f72ab94853 GDB monitor test for automatic testing
The following features are tested (currently on Fiasco.OC only):

- breakpoint in 'main()'
- breakpoint in a shared library function
- stack trace when not in a syscall
- thread info
- single stepping
- handling of segmention fault exception
- stack trace when in a syscall

This patch fixes #105.

da5bf709e6 Consider count_in in Noux terminal-read function
It does not suffice to constrain the amount of returned data with chunk
size of the transport buffer because the client may have specified an
even smaller value. For example, libreadline reads single characters
from the terminal and expects a single character in return. A different
amount is interpreted as EOF.

cc85dc8afb Let GDB monitor use HLT for breakpoints, fix #83
The patch fixes a corner-case problem with using the two-byte 'INT 0'
instruction for breakpoints. The fix changes the breakpoint instruction
to the single-byte 'HLT'. 'HLT' is a privileged instruction and triggers
an exception when executed in user mode. Patch by Christian Prochaska.

441d672440 Improved interactive GDB monitor run script
The new 'gdb_monitor_interactive.run' script extends the original
'gdb_monitor.run' script with a startup sequence that automates the
initial break-in at the main function of a dynamically linked binary.

8c3f832f09 Noux: quote env values, fix #66
When reading the values of environment variables supplied via Genode
config mechanism, the XML attribute values were taken as is. On the libc
side, however, the values are processed using Genode's 'Arg_string'
functions. When unquoted, 'Arg_string' expects values to be either
identifiers or numbers. In the general case, however, env values cannot
be expected to satisfy these requirements. Hence, it is better to always
quote these values when reading the XML config. An alternative (maybe
better) solution would be to not use the 'Arg_string' classes in the
libc side.

b5d7a75a22 Return ECHO flag from TIOCGETA ioctl
This patch sets the ECHO flag for the TIOCGETA ioctrl operation. This
flag is examined by libreadline to control the policy of echoing user
input. This patch in needed to run bash in interactive mode in Noux.
