b157256a2b uplink client: Add missing space in warning message.
Right now the warning about failure to forward packet from driver to
uplink RX connection reads:

  "exception while trying to forward packet from driverto Uplink
   connection TX"

Add missing space between "driver" and "to".

60980045ea virtio_nic: Increase default TX & RX virtqueue sizes.
32KB is a rather small value. The driver can cope with it now, but
it does not perform as well as it should. This visible especially
in scenarions like nic_router_flood where we still often hit
synchronous wait path. Bump the size to 256kB.

880cd3a490 virtio_nic: Fix packet transmission handling.
The problem can be seen when running nic_router_flood scenarion on arm
qemu_virt boards. With the amount of data this scenario tries to send
the driver quickly complains it has failed to push data into TX VirtIO
queue. After this warning message is printed nothing really happens and
after a while the test scenario fails.

The fact that we can't write all available data to the device is not
unexpected. VirtIO queue size is slected at initialization time and we
don't change it during driver lifetime. It can be tweaked via driver
config, but this does not change the fact that we'll always be able to
produce more data packets than we have free space in the VirtIO queue.

IMO the expected behavior of the driver in such case should be to:
1. Notify the device there is data to process.
2. Wait for the device to process at least part of it.
3. Retry sending queued packets.

One could expect returning Transmit_result::RETRY from _drv_transmit_pkt
would produce such result. Unfortunately it seems that Uplink_client_base
treats RETRY return value as indication of link being down. It'll retry
sending the packet only after the device notifies it the link is once
again up. This is the reason why nothing happens when running
nic_router_flood on top of virtio_nic driver. The link never goes down
in this case so once we fill the TX VirtIO queue and tell the base class
to retry the send, we'll be stuck waiting for link up change event
which will never arrive.

To fix this problem, when sending a packet to the device fails, do a
synchrnonus TX VirtIO queue flush (tell device there is data to process
and wait until its done with it).

With this fix in place nic_router_flood test scenario passes on both arm
qemu_virt boards.

3daa94ff2e gpu/intel: Add support for Gen9+
This commit contains features and buf fixes:

* Catch errors during resource allocation

* Because Mesa tries to allocate fence (hardware) registers for each
  batch buffer execution, do not allocate new fences for buffer objects
  that are already fenced

* Add support for global hardware status page. Each context additionally
  has a per-process hardware status page, which we used to set the
  global hardware status page during Vgpu switch. This was obviously
  wrong. There is only one global hardware status page (set once during
  initialization) and a distinct per-process page for contexts.

* Write the sequence number of the currently executing batch buffer to
  dword 52 of the per-process hardware status page. We use the pipe line
  command with QW_WRITE (quad word write), GLOBAL_GTT_IVB disabled
  (address space is per-process address space), and STORE_DATA_INDEX
  enabled (write goes to offset of hardware status page). This command
  used to write to the scratch page. But Linux now uses the first
  reserved word of the per-process hardware status page.

* Add Gen9+ WaEnableGapsTsvCreditFix workaround. This sets the "GAPS TSV
  Credit fix Enable" bit of the Arbiter control register (GARBCNTLREG)
  as described by the documentation this bit should be set by the BIOS
  but is not on most Gen9/9.5 platforms. Not setting this bit leads to
  random GPU hangs.

* Increase the context size from 20 to 22 pages for Gen9. On Gen8 the
  hardware context is 20 pages (1 hardware status page + 19 ring context
  register pages). On Gen9 the size of the ring context registers has
  increased by two pages to 21 pages or 81.3125 KBytes as the IGD
  documentation states.

* The logical ring size in the ring buffer control of the execlist
  context has to be programmed with number of pages - 1. So 0 is 1 page.
  We programmed the actual number of pages before, leading to ring
  buffer execution of NOOPs if page behind our ring buffer was empty or
  GPU hangs if there was data on the page.

59b23bc7e1 libdrm: Iris - execute batch buffer synchronous
* Wait for for completion before return from 'execbuffer2'. This makes
  buffer execution synchronous.

* Because the Iris driver manages the virtual address space of the GPU
  and creates one GEM context for each batch buffer we have to map/unmap
  all buffer objects before and after batch buffer execution.

d072c408ab dde_linux: call init_page_count for each page
The lx_emul_virt_to_pages implementation initialized the page ref
counter only for the first page, leaving the remaining elements in
uninitialized state. This, in turn, rendered the Linux page_pool (as
used by the emac network driver) ineffective, ultimately leading the a
memory leak. The fix changes the call of 'init_page_count' to take the
loop variable as argument.

e6c915ae06 libssh port: immediate mode for ssh poll
This patch adds a switch to internal poll function in libssh that
allows to force this function to immediately return without actually
polling for data and in consequence processing this data. This switch
is used to avoid calling callback functions when flushing output
streams which caused locks due to recursive access to internal

f1b72d0281 cxx: define delete operator with alignm. arg
Using 'alignas' in declarations might cause GCC to request for an
implementation of 'operator delete(void*, unsigned long, std::align_val_t)'
although it might actually never be called. This commit adds a dummy
implementation to 'cxx/new_delete.cc' that does nothing more than printing an
error to the log that a proper implementation is missing. This approach is
coherent with our treatment of other global delete operators.

ebd140cacb reconstructible: respect alignment of payload
If one has an object X that has a minimum alignment requirement specified
through 'alignas' this requirement is normally inherited by objects that have
object X as member, and by those that have objects as member that have X as
member, and so on... . However, this chain used to get silently interrupted
(dropping the minimum alignment requirement to 8 again) at objects that are
managed with Genode::Reconstructible or Genode::Constructible. In order to fix
this, the commit ensures that Genode::Reconstructible (and therefore also
Genode::Constructible) has at least the minimum alignment requirement (using
'alignas') as the object it manages.

7fdebc6a09 nic_router: let DHCP client request domain name
The NIC router parses, stores and forwards DNS domain names from DHCP replies.
Yet the routers DHCP client used to not request DNS domain-name information on
DHCP requests. This caused DHCP servers to skip this information on their
replies although it was available. This commit fixes the issue by adding the
DNS domain name code to the request parameter list of requests from the routers
DHCP client.

c95af254f4 lx_emul: sanitize size 0 for __kmalloc
Driver code such as mfd-core.c may pass 0 as argument n to kcalloc,
which eventually results in an allocation size 0.

  res = kcalloc(cell->num_resources, sizeof(*res), GFP_KERNEL);

Since 'res' is checked against NULL for success, kmalloc must not return
a NULL pointer in this case. The patch works around this issue by
forcing an allocation size of 1 byte in this case.

29032caf40 lx_emul: support CLK_OF_DECLARE initcall mechanism
Clock providers such as drivers/clk/sunxi-ng/ccu-sun8i-r.c don't use
regular init calls but declare their init functions via CLK_OF_DECLARE,
which fill the __clk_of_table. Linux populates the table statically by
using special sections declared in the linker script. In contrast, we
populate the table by expanding the macro to global constructor
functions.

The __clk_of_table is then processed by the call of of_clk_init(NULL).

812fdec27c nic_router: propagate dns domain name via dhcp
With this commit, the NIC router DHCP client reads out the first DNS domain
name (DHCP option 15) if any from a DHCP reply that generates an IPv4 config
for a domain and stores the name together with the IPv4 config for that domain.
DNS domain names are reported via the new report tag '<dns-domain>' if the
'config' attribute in the config tag '<report>' is set.

Furthermore, the NIC router DHCP server becomes able to obtain a DNS domain
name from another domain that has a DHCP client dynamically (given the config
attribute 'dns_config_from' is set and no static DNS config is given) or
statically from its configuration (new config tag '<dns-domain>') and propagate
this name with DHCP replies (DHCP option 15).

The 'nic_router_dhcp_*' tests are adapted to test the new feautures.

The commit also gets rid of some mirrored files in
'test/nic_router_dhcp/manager'.

fa64aae7f8 nic_router: config attribute 'dns_config_from'
WARNING: 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 'dns_server_from' attribute in a NIC router
configuration replace the attribute name with 'dns_config_from'. The attribute
value remains unaltered.

DETAILED DESCRIPTION

The new attribute name 'dns_config_from' reflects that also other aspects of
the DNS configuration of the denominated domain are used by the DHCP server
that holds the attribute. This commit is a preparation for forwarding also the
domain name (DHCP option 15) with the mechanism behind the attribute.

1111472af7 nic_router: make Ipv4_config a class
The fact that the IPv4 config was a struct with all data members public was a
mere leftover of an early state of the NIC router. Today, the router
implementation style is to avoid structs and public data members wherever
possible.

This commit slightly changes the behavior of the router regarding log output.
The router used to print malformed IPv4 configurations to the log only if
the 'verbose' config flag was set using this style:

! [my_domain] malformed dynamic IP config: interface 10.0.2.1/24 ...

Now, malformed IPv4 configurations are only printed if the
'verbose_domain_state' config flag is set (like with any IP4v configuration
states) using this style:

! [my_domain] dynamic IP config: malformed (interface 10.0.2.1/24 ...)

e648e7255a nic_router: optional icmp type 3 on fragm. ipv4
Via a new configuration attribute, the user can decide whether the router
should answer dropped fragmented IPv4 with an ICMP "destination unreachable"
packet and, if so, which value the ICMP code field of this packet should have.
The default is that the router doesn't send such responses (silently dropping
fragmented IPv4). 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.

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.

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.

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:

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

only the leaf node was empty.

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.

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.

<new-file path="...">...</new-file> tag will cause creation or overwriting of
the file given through the 'path' attribute. The file will contain the text
content of the tag.

100583e262 os/vfs.h: New_file utility
This patch moves the utility from the app/text_area to os/vfs.h to make
it easier to use by other components. By hosting the 'New_file' as a
friend alongside the 'Directory', we can now pass a 'Directory' as
constructor argument, which is consistent with other utilities such as
'File_content'.

As a further improvement, the new version supports the implicit creation
of the directory hierarchy leading to the new file.

  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

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.

  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.

f236e99b5c ssh_terminal: avoid deadlock of EP and pthread.0
pthread.0 acquires a write buffer mutex and calls potentially
blocking fs operations. The EP thread handles session requests and tries to
acquire the same write buffer lock. IO progress events for pthread.0 are
handled by the EP thread, which however is blocking on the write buffer mutex.

The commit uses two write buffers, one which is filled by the EP and a second
which is used by pthread.0. The two buffers are swapped protected by a mutex
without invoking blocking fs operations.

The fix is just for consistency reasons, as sculpt manager is generating the
event_filter.config anyway.

f6aabfe233 Sculpt: prevent nitpicker's resize warnings
This patch increases the RAM quota of the top-level nitpicker instance
to 12 MiB so that resize operations can be buffered for resolutions up
to 2560x1080. It mutes diagnostic messages of the form "Warning: Gui
(...) not enough RAM to preserve buffer content during resize" and
improves the window-resize experience.

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.

Fixes genodelabs/genode#4093

Also fixes a bug in `vpa()` and `vpb()` which moved the cursor
horizontally instead of vertically.

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.

bb6617ad03 New libc_integration test
I created a test program which stresses the interplay between libc,
pthreads and vfs_pipe and may detect regressions.

The program starts a thread that spawns a bunch of workers, sends and
receives data to them through a pipe. When all data of a worker is
collected, the worker is finished (join()) and a new worker is started.
Both the number of bytes sent to the worker and the size of its
answer are random.
