06a4608f4a nic_router: report dropped fragmented IPv4
If the new attribute 'dropped_fragm_ipv4' of the <report> tag in the NIC router
config is set "yes", the router will report the number of packets that were
dropped per interface respectively domain because fragmented IPv4 is not
supported. The default is not to report the counter. The behavior is tested by
the 'nic_router_ipv4_fragm' test.

619474bc90 nic_router: drop fragmented IPv4
The NIC router used to ignore the IPv4 header fields "More fragments" and
"Fragment offset" completely. Therefore higher-level protocols of fragmented
IPv4 were interpreted wrong because each fragment was considered a self-
standing packet, expecting, for instance UDP/TCP headers somewhere inside of
the UDP/TCP data field. Normally, such packets were dropped as soon as the
UDP/TCP checksum check failed because of the misinterpretation. However,
it was also possible for fragmented IPv4 to pass the router although normally
only partially.

IPv4 fragmentation support in the router would introduce some potential
security risks and is presumably not an easy endeavor. So, for now, we settled
on not supporting IPv4 fragmentation. With this commit, the router simply drops
all fragmented IPv4. This is reflected to the log for each fragment as "drop
packet (fragmented IPv4 not supported)" when 'verbose_packet_drop="yes"' is
configured.

The new test 'run/nic_router_ipv4_fragm' is an automated test for this
behavior. The test is added to the autopilot list.

2533d7b4b6 vfs/fatfs: cleanup implementation
- remove redundant file system factory

- remove dead code block

  The code was guarded by preprocessor directives checking whether the
  contrib code define "_USE_MKFS" is 1. As "_USE_MKFS" is not set one
  for our port of FAT, the code was never executed and can be removed.

- remove uneffective config attributes

  Apparently, the former XML attributes to the plugin 'drive' and
  'codepage' had no effect. I tested them in a scenario with the VFS
  block server on a disk-image boot-module as back end. Regardless of
  the 'drive' value, the block session label was always "0". Regardless
  of the 'codepage' value, the FAT on the disk image succeeded to mount
  when not using '--codepage' for 'mkfs.fat' and failed to mount when
  using '--codepage' to specify a supported but foreign codepage for
  'mkfs.fat' (e.g. "720").

60c8369718 lib/fatfs: get rid of global static constructors
There was one global static constructor:

! namespace Fatfs { static Constructible<Platform> _platform; }

This caused applications that used the lib or the <fatfs> VFS plugin to end up
in an uncaught exception due to Genode::Component complaining that method
'construct' returned without executing pending static constructors if they
didn't call Genode::Env::exec_static_constructors().

As the use of Genode::Env::exec_static_constructors() is discouraged in Genode,
this commit rather moves the '_platform' object to the scope of the
initializing function and introduces a global static pointer to the object that
gets set by the initializing function. Although this prevents the exception, it
is, technically speaking even worse than the former solution as the new pointer
isn't checked for validity in contrast to the 'Constructible' object.

However, so far, I don't see a clean solution to this problem without the need
for Genode::Env::exec_static_constructors().

f8953de7ac nic_router: replace term "uplink" with "NIC client"
BREAKS CONFIG COMPATIBILITY:
This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!

HOW TO ADJUST:
At each occurrence of the '<uplink ...>' tag in a NIC router configuration
replace the tag name 'uplink' with 'nic-client'. The rest of the tag stays the
same.

The term "uplink" for network interfaces in the router that have a NIC session
client as back end was introduced in a time when Uplink sessions didn't yet
exist. Now, they do and, although both an uplink and an Uplink session
normally describe a network session between router and network device driver,
they are based on two different service types (NIC and Uplink). This can easily
cause confusion when integrating the router (the <uplink> is not related to
Uplink sessions) or trying to understand its functioning (an 'Uplink' object
has nothing to do with the Uplink service).

Therefore, this commit introduces the more specific term "NIC client" for an
interface that is based on a NIC session requested by the router. This doesn't
imply any semantic changes at the NIC router. However, the commit also brings a
broader update of the router's README and removes the term "downlink" that was
used only in documentation to refer to interfaces backed by a NIC session
provided by the router. The term was only associated with this meaning because
it is the natural counterpart to an uplink. This isn't appropriate anymore as
the terms for interface types have moved to a more technical level.

The commit adjusts all scenarios in the basic Genode repositories properly.

2afae7e7c1 nic_router: uncaught exc. on handling link state
An interface that received a signal for a link-state change accessed its
domain reference without assuming that it could not be attached to a domain
at that moment. This caused the NIC router to crash with an uncaught exception
of type 'Net::Pointer<Net::Domain>::Invalid'. The commit adds a catch
directive for this exception resulting in the handler doing nothing if not
attached to any domain.

d06773b957 run/tz_vmm: remove usb_armory support
The test script failed during preparation of the on-target execution for
USB Armory with the following error:

Presumably, the script wasn't run anymore since the introduction of the
'tz_vmm_block_irq' variable for i.MX53 QSB. As we do not have infrastructure
for automated testing of the USB Armory and there seems to be not much
interest in using Genode on this platform, this commit simply removes the
support from the script.

8bc861ca71 nic_router: do not re-use ARP request as reply
So far, in order to create an ARP reply, the NIC router merely created a copy
of the corresponding ARP request and modified only those values that differ.
This approach has the disadvantage of re-using bad parameters from a broken
request. The specific use-case that made this visible was an early version of
the Pine board network driver that used to forward ARP requests with a greater
size than required. The ARP replies of the router re-used this size and
confused other network nodes with that. In general, the NIC router should
rely on the data of incoming packets the least possible. Therefore, with this
commit, the router creates a new ARP reply from scratch and uses only those
values required from the corresponding ARP request.

It tries to meet the original semantic of the Linux kernel

1aba330ae6 dde_linux: fix packet size calc. of Nic drivers
skb_push() already increases the skb->len by ETH_HLEN, hence adding
ETH_HLEN to the packet_size is redundant.

A too large packet size becomes a problem for large MTUs. With a maximum
MTU of 1500, adding ETH_HLEN twice will lead to a packet size of 1528.
Since this is larger than what we expect for good-old Ethernet (max. 1522),
some clients (e.g. the e1000 model in vbox5) may drop these packets.

5138aeba80 libc: fix nested monitor call in 'symlink'
The symlink implementation wrongly constructed a 'Sync' object within
the context of a monitor call. The 'Sync' constructor indirectly
depended on libc I/O for obtaining the current time, ultimately
resulting in a nested attempt of a monitor call. This could be
reproduced via the base.run script:

  $ cd /home
  $ ln -s a b

The 'ln' command resulted in the following log message:

  [init -> /bin/bash -> 7] Error: deadlock ahead, mutex=0x10ff8c70, return ip=0x500583a7

The patch fixes the problem by splitting the single monitor call into
two monitor calls and moving the construction of the 'Sync' object
in-between both monitor calls, thereby executing the constructor at the
libc application level.

688379d1ed sel4: fix segmentation fault with CCACHE=yes
Building the elfloader in kernel-sel4.inc has a problem with Genodes CCACHE

..., building the elfloader used to consume all memory of the host system and
then run into a segmentation fault:

! make[6]: *** [elfloader/elfloader.o] Segmentation fault (core dumped)

This is because the other build system invokes the CCACHE variable as a command
in front of the compiler command. If CCACHE is set to 'yes', the 'yes' command
is called and produces an endless output into some output file. The problem
can be fixed by locally re-setting the CCACHE variable for the
'make ... elfloader' command to 'ccache' (Genode CCACHE==yes) or '' (Genode
CCACHE!=yes).

2d017ad7b7 nic_router: guard against exception in free_ip
Adds try-catch-statement with diagnostic errors in Dhcp_server::free_ip in
order to guard against exceptions from the underlying bit allocator. These
exceptions should never happen given that the router is programmed correctly
and always feeds Dhcp_server::free_ip with sane arguments (which it should).
However, should this not be the case, we can assume that the failed IP freeing
indicates that the IP isn't allocated anyway and it's fine to continue using
the router. Furthermore, IP allocations are a mere client service and not
relevant for the integrity or safety of the router.

be644098d7 nic_router: fix exc. in Interface::handle_config_3
When Interface::handle_config_3 (third step of applying a new configuration to
interfaces) tried to detach the interface from the current IP config because
the old and new IP config differed, it did so using the new domain. The former
steps of the reconfiguration already installed the new domain reference at the
interface. Therefore, also the DHCP server of the new domain was used. This,
however caused uncaught exceptions because detaching from an IP config
includes dissolving all DHCP allocations. This dissolving of DHCP allocations
now operated on a DHCP server (the one of the new domain) that wasn't related
to the allocations and, in the worst case, caused an uncaught exception
because the IPs were out of its range.

That said, this commit ensures that detaching an interface from an IP config
is always done on the domain from which the IP config originated. Normally,
this is the domain the interface is attached to. But in the case of
Interface::handle_config_3, it is another - the former domain the interface
was attached to.

The commit also adapts the nic_router_dhcp_* tests in a way that they
reconfigure the router in a way that would trigger the uncaught exception
without the fix.

Adapts Dir_file_system::open_composite_dirs in a way that it returns "success"
when the leaf node of the path is an empty directory but "lookup failed", as
usual, if one of the other directories on the way to the leaf node is empty.

I couldn't find a technical reason why we used to return "lookup failed" when
only the leaf node was empty.

The commit also adds a test for en empty root directory and empty
sub-directories to the fs_query run script.

6bfdddd0b5 fs_query: gracefully deal with missing directories
The fs_query component used to exit with an uncaught exception if a queried
directory didn't exist. Now, fs_query will catch this event and simply skip the
affected query, thereby indicating to the user the inexistence of the
queried directory.

ff128df131 dde_linux/fec: fix unsynchronized TX DMA write
Unfortunately, our current implementation of 'wmb()' doesn't seem to do what we
want it to do. On base-hw + imx6q_sabrelite, the write of bdp->cbd_sc seems to
get re-ordered after the write to txq->bd.reg_desc_active in the transmission
path of the contrib code. Due to this, the transmission of the packet is only
triggered the next time a packet is sent. However, we only quick-fix it by
enforcing the execution of the write with a volatile global read as we will
soon update the FEC NIC port with a new DDE approach anyway.

331844c979 vbox6: support capslock="rom" mode
In ROM mode the global CapsLock state is controlled by the capslock ROM
by virtual KEY_CAPSLOCK events.

Guests are easily confused by spurious KEY_CAPSLOCK input events in
caps="rom" mode. These spurious events may reach the VMM if KEY_CAPSLOCK
is not pressed as first key in a combination and, therefore, is not
filtered as global key. We filter KEY_CAPSLOCK in ROM mode in the VMM
explicitly, but let it pass in non-ROM mode.

Per default RAW mode is used and CapsLock key events are sent unfiltered
to the guest.

813f4d976b lxip: allocate skb with properly aligned IP header
Comment in Linux sources:

  Since an ethernet header is 14 bytes network drivers often end up with
  the IP header at an unaligned offset. The IP header can be aligned by
  shifting the start of the packet by 2 bytes. Drivers should do this
  with:

  skb_reserve(skb, NET_IP_ALIGN);

This is ensured when using netdev_alloc_skb_ip_align().

a24224ffc3 usb_host: improve isochronous performance on Intel
This patch takes advantage of block transfer interrupts on Intel XHCI
controllers which is used during isochronous transfers. Because of a bug
in hardware (see usb_host_isoc_bei.patch header), this feature has been
disabled for Intel leading to up to 8000 interrupts/s for isochronous
transfer causing severe CPU consumption on Genode. With this commit we
lower host driver consumption to normal levels.

a4115cfea9 base-linux: discharge timestamp on AARCH64
The kernel-agnostic 'Trace::timestamp' function for arm_64 executes the
'mrs %0, pmccntr_el0' instruction, which is not permitted for user-level
programs on Linux. This patch shadows the generic timestamp.h header
with dummy that returns zero. This return value prompts the timeout
framework to disable the interpolation of time based on timestamps. This
avoid the illegal-instruction abort but comes with two llimitations:

First, time measurements are effectlively limited to a granulariry of 1
millisecond (deliberately constrained by the timer driver).

The quirk is applied when using the base-linux API. Should a generic
application (that uses the base API only) call 'Trace::timestamp'
directly, the illegal instruction is executed.

This patch adds support for running Genode/Linux on the AARCH64

  capture the initial stack pointer, which the Linux kernel uses
  to pass the process environment. This is in line with the
  existing startup code for x86_32 and x86_64.

- The link order of the host libraries linked to lx_hybrid
  programs had to be adjusted such that libgcc appears at last
  because the other libraries depend on symbols provided by
  libgcc.

- When using AARCH64 Linux as host, one can execute run scripts
  via 'make run/<script> KERNEL=linux BOARD=linux' now.

fdb1a4dd88 base-linux: avoid legacy syscalls
Until now, Genode's Linux system call bindings were based on original
Unix system calls that were later superseded by more flexibile variants.
E.g., 'openat' is a modern version of 'open'. Even though Linux upholds
the compatiblity with the original versions for existing architectures
like x86, the legacy syscalls are absent for the recently added AARCH64
architecture. A good overview of the system calls accross the prominent
architectures can be found at

https://chromium.googlesource.com/chromiumos/docs/+/master/constants/syscalls.md

This patch updates Genode's syscall bindings to avoid legacy versions,
thereby easing the support for AARCH64. The used "modern" versions
were introduced back in Linux version 2 days. So we are fine to rely
on them.

The patch slightly changes the signature for lx_stat because this system
call is merely used to check for the existance of a file and its size.
The new name 'lx_stat_size' draws a closer connection to its use case.
That said, the stat syscall has not been updated to the modern statx
since statx is still a fairly recent addition.

d477062c56 base-linux: simplify clone syscall binding
This patch simplifies the use of the clone system call for creating
processes and threads. Until now, the binding used an opaque pointer
argument to pass context information to the newly created process or
thread. However, upon close inspection, this is not a strict
requirement.

A newly created thread accesses its contextual information by
using its stack pointer as key. The pointer argument is not used.

The creation of processes is strictly serialized because the
intermediate stack used in-between clone and execve is a global
variable. Since we rely on the serialization anyway, we can pass the
context information of a new process via a global variable as well.

This change simplifies the syscall binding for the upcoming AARCH64
support, which would otherwise require us to deal with the notion
of TLS on Linux.

49184fb938 net: circumvent stringop-overflow error
With the update to GCC 10, the compiler stopped with an error when compiling
places where a MAC address is copied from outside into a packed object using
the Net::Netaddress::copy method (e.g. in
Net::Arp_packet::dst_mac(Mac_address)):

! error: writing 6 bytes into a region of size 4 [-Werror=stringop-overflow=]

While trying to find a clean solution for this error, I found posts on
gcc.gnu.org and github that stated that the size calculations that cause these
errors are incorrect. Indeed, I could verify that the actual size of the two
regions was static and exactly the same in places were the error occured.

Furthermore, I couldn't find a way of making it more clear to the compiler
that the sizes are the same. By accident, we found that using the address of
the first element of the array that forms the second region instead of the
array address itself, somehow circumvents the error.

52e8c95321 net: fix packed-conversion compiler warning
With the update to GCC 10 the compiler used to warn when using the internet
checksum functions on packet classes (like in
Net::Ipv4_packet::update_checksum):

warning: converting a packed ‘Net::[PACKET_CLASS]’ pointer
         (alignment 1) to a ‘const uint16_t’ {aka ‘const short
         unsigned int’} pointer (alignment 2) may result in an
         unaligned pointer value

Apparently, the 'packed' attribute normally used on packet classes sets the
alignment of the packet class to 1. However, for the purpose of the
internet-checksum functions, we can assume that the packet data has no
alignment. This is expressed by casting the packet-object pointer to a pointer
of the new packed helper struct 'Packed_uint16' that contains only a single
uint16_t member before handing it over to the checksum function (instead of
casting it to a uint16_t pointer).

4e822436fc nic_router: use increasing src port for new nat
The NAT feature of the NIC router used to prefer re-using source ports that
have been freed recently. From an external server's perspective, if a client
dies and restarts, chances are high that the new connect arrives with the same
source-IP/source-port as the old connection. The server has to forcefully reset
the connection. If that happens a lot, the server may even start to ignore
further connections from this IP/port combination for a while as a mitigation.

This patch adds a continuous counter feature that makes sure that every new
port allocation will increment and result in a port that hasn't been used for a
long time.

The NAT feature of the nic_router is now more in line with RFC 6056 chapter 4.

1c49da8ce4 terminal: don't overwrite last column until eol
Introduce a new _overflowed state variable to indicate whether the
horizontal boundary was reached already and to omit subsequent character
output.

This state is necessary to maintain a valid cursor position at all
times. The _overflowed attribute is reset once the cursor is moved into
a valid position again.

To harmonise the bounds checking for _cursor_pos modifications, the
`constrain()` method was added.

Also fixes a bug in `vpa()` and `vpb()` which moved the cursor

9cb8c37e3a terminal: fix sporadic freeze on font-size changes
The direct execution of application-level code by a watch handler is
troublesome because those handlers are executed at the I/O signal level.
In the concrete case, the watch handler got recursively called because
the handler called _handle_config (application-code), which called the
VFS, which in turn performed a wait_and_dispatch_one_io_signal, which
again invoked the watch handler.

The patch works around the problem by letting the watch notification
trigger the application-level signal for the _config_handler.

d73eaaa14c libc: exclude arm_initfini.c
This compilation unit contains a global constructor, which violates our
assumption that the libc is free of global constructors on ARMv7.
Specifically, the graphical terminal fails with the following message:

[init -> terminal] Error: Component::construct() returned without executing
                          pending static constructors (fix by calling
                          Genode::Env::exec_static_constructors())
[init -> terminal] Error: Uncaught exception of type 'Linker::Fatal'

In this case, the libc-less terminal uses the VFS. The VFS mounts the
ttf VFS plugin. The ttf VFS plugin depends on the libc.

The compilation unit 'arm_initfini.c' can safely be excluded because it
merely initializes the global '_libc_arm_fpu_present' variable, which
is not used by the current version of our libc/libm.

dc8c899c1d Streamline platform-device API on ARM
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of

- Platform::Device       - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq  - interface for receiving device interrupts

The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.

80cf47d906 ldso: protect object list with mutex
When we allowed symbol resolution during exceptions, we used the shared
object lock to protect ELF object list manipulation (e.g., dlopen,
dclose) when executing exception unwinding code in the linker.
Unfortunately, sometimes libraries that are loaded by 'dlopen' may raise
exceptions in the process, leading to a deadlock within the unwind code.
In order to resolve this, we now protect the object list operations
(i.e., enqueue, removal, iteration) by a separate mutex. This allows
the shared object interface to throw exceptions.

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.

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.

GDB monitor re-uses internal parts of the sandbox library. It thereby

This patch makes the GDB monitor less reliant on the way of how the

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.

This patch enables sculpt to utilize the CPU reset mechanism via the

information. Whenever the /config/system file is changed to <system

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.

2c7c7767fc platform_drv: respond to <system state="reset"/>
If 'system="yes"' is specified in the <config>, the platform driver now
monitors the content of the system ROM. Should the value become "reset",
a reset is triggered using information obtained from the ACPI driver.

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.

8f1db47c26 sculpt: screen capturing and event injection
This patch adds session-routing options to connect components to the
capture/event interfaces of the global nitpicker GUI server or the
leitzentrale GUI server. It thereby enables the implementation of screen
capturing components, remote management tools, or virtual keyboards.

Since those services are very powerful, they are subsumed under the
"hardware" category of the component graph as opposed to the GUI
category, which guarantees the separation of clients.

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!

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.
