365d0bccd5 init.run: prioritize timer over test
The 200-second timeout of the init test triggers on some test platform
(in particular on qemu) while it is overly pessimistic on others.
This patch aims at stabilizing the timing behavior of the test across
the tested kernels/machines.

3bbeacad20 init: preserve final state of exited children
This is a follow-up patch of "init: avoid too eager child restart". On
each config update of init, init re-applies child-specific configuration
changes. In the case of an already exited child, this re-evaluation
wrongly marked such a child as abandoned because the child's environment
sessions do no longer exist. Abandoning the child, in turn, triggers the
destruction and subseqent restart (because the <start> node of the
configuration still exists). The latter is bad for two reasons.

First, the exit state of the original instance becomes lost. Second, the
restart may have unexpected side effects due to sessions created by the
new instance. I.e., when resizing a partition in sculpt, init would
wrongly restart the gpt-write tool after the tool successfully exited.
This collides with a newly started instance of part_blk/resize2fs, which
now competes with the second gpt-write instance for the exclusive access
of the targeted block device.

The patch prevents init from re-applying configurations to exited
children. The accompanied test case covers the corner case.

2af9cb7952 nic_router_flood.run: be more flexible
Do not simply wait for the good ping test to finish, but for the other
flood tests to trigger the RAM exhaustion. This makes the test more
robust with slower platforms or a different timing.

49a3a0e0d0 nic_router: multiple uplinks
Introduce the uplink tag:

! <config>
!    <uplink label="wifi"  domain="uplink">
!    <uplink label="wired" domain="wired_bridge">
!    <uplink               domain="wired_bridge">
! <config/>

For each uplink tag, the NIC router requests a NIC session with the
corresponding label or an empty label if there is no label attribute.
These NIC sessions get attached to the domain that is set in their
uplink tag as soon as the domain appears. This means their lifetime is
not bound to the domain. Uplink NIC sessions can be safely moved from
one domain to another without being closed by reconfiguring the
corresponding domain attribute.

Attention: This may render previously valid NIC router configurations
useless. A domain named "uplink" doesn't automatically request a NIC
session anymore. To fix these configurations, just add

! <uplink domain="uplink"/>

or

! <uplink label="[LABEL]" domain="uplink"/>

as direct subtag of the <config> tag.

14357b0b44 nic_router_flood.run: test DoS against router
Currently has three clients that continuously create new UDP/TCP/ICMP
connections through the NIC router with NAT to the outer world and they
get never closed.  A fourth client does normal ping through the same
domain to the outer world that must succeed even after the RAM quota of
the other session at the router is exhausted. The test is restricted to
Qemu to not being at risk to flood real networks.

1330c27ac6 ping.run: mark as "not supported" on Linux & FOC

1af6bd1454 Fs_rom: send signals on file removal

7b6b3a4535 base: fix destruction of async env sessions
When an environment session is provided by a async service such as a
sibling component, the session metadata must be preserved until end of
the lifetime of the session at the server has been acknowledged by the
server. Since the session meta data of env sessions are always part of
the 'Child' object, the destruction of this object must be deferred
until this point.

980f3e9c5c net: use Size_guard for packet-data accessors
Instead of handing over the maximum available size to the packet data
accessors, hand over a size guard that keeps track of the packets
boundaries.

This commit also moves the size-guard utilitiy header of Ping and NIC
Router to the include/net directory making it a part of the net library.
It applies the new approach to all net-lib users in the basic repositories.

Ping looses its configurability regarding the ICMP data size as this would
require an additional method in the size guard which would be used only by
Ping.

The size guard was also re-worked to fit the fact that a packet can
bring a tail as well as a header (Ethernet).

84a3fbd239 app/ping: perform ICMP Echo to another IP host
The 'ping' component continuously sends ICMP Echo requests to a given IP host
and waits for the corresponding ICMP Echo replies. For each successfull ICMP
Echo handshake it prints a short statistic. By now, it can be used only with a
static IP configuration. The size of the ICMP data field can be configured. It
gets filled with the letters of the alphabet ('a' to 'z') repeatedly.

3778558608 os: reworked nitpicker_gfx/text_painter.h
This patch improves the `Text_painter` utility that is commonly used by
native Genode components to render text:

- Support for subpixel positioning
- Generic interface for accessing font data
- Basic UTF-8 support

Since the change decouples the font format from the 'Text_painter' and
changes the API to use the sub-pixel accurate 'Text_painter::Position'
type, all users of the utility require an adaptation.

4a3fc21ada New watch handle mechanism for File_system session
File_system clients may now watch files and directories for changes by
opening a 'Watch_handle' rather than submitting a 'CONTENT_CHANGED'
packet to the server. When a change happens at a node with an open
Watch_handle a CONTENT_CHANGED packet will be sent from the server to
the client. This serializes registration with other handle operations
and separates I/O handle state from notification handle state.

Test at run/fs_rom_update.

ccc67d6f68 trace_logger: convenient tracing frontend
The 'trace_logger' component can be used to easily gather, process and export
different types of tracing data. Which subjects to select is configurable via
session label policies and thread names. Which data to collect from the
selected subjects can be configured for each subject individually, for groups
of subjects, or for all subjects. The gathered data can be exported as log
output.

This is an example configuration of the 'trace_logger' component which shows
the default value for each attribute except the policy.thread and
policy.label:

! <config verbose="no"
!         session_ram="10M"
!         session_arg_buffer="4K"
!         session_parent_levels="0"
!         period_sec="5"
!         activity="no"
!         affinity="no"
!         default_policy="null"
!         default_buffer="4K">
!
!    <policy label="init -> timer" />
!    <policy label_suffix=" -> ram_fs" />
!    <policy label_prefix="init -> encryption -> "
!            thread="worker"
!            buffer="4K"
!            policy="null" />

3d12e7b242 timeout x86_64 sel4: do not expect a precise time
On x86 64 bit with SeL4, the test needs around 80MB that must be
completely composed of 4KB-pages due to current limitations of the SeL4
port. Thus, Core must flush the page table caches pretty often during
the test which is an expensive high-prior operation and makes it
impossible to provide a highly precise time.
