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 ...)

9e6f7988c2 nic_router: list dns servers in one dhcp option 6
The NIC router DHCP server used to add an extra option 6 field to DHCP replies
for each DNS server address. This conflicts with RFC #2132 section 3.8 which
states that the addresses should be listed within one option 6 field without

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.

06a4608f4a nic_router: report dropped fragmented IPv4

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.

attached to any domain.

for automated testing of the USB Armory and there seems to be not much

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.

The former declaration of the IPv4 packet did not only use the questionable
tool of implementation-defined C++ bitsets but also lacked access to flags
"don't fragment" (DF) and "more fragments" (MF). This commit replaces the
C++ bitsets by using the register framework and introduces accessors for the
missing flags.

1a526e73a3 dde_linux: introduce new lx_emul/lx_kit library
The re-newed approach currently supports ARM 64-bit only.
It depends on the Platform API of the ARM architecture.
It tries to meet the original semantic of the Linux kernel
functions as far as possible. To achieve this, device drivers
using this library should reference the original Linux kernel
headers at foremost. Only the headers in `src/include/lx_emul/shadow`
have to shadow clone the original ones.

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
make variable. When issuing ...

! ./tool/depot/create mstein/bin/*/base-sel4-* CCACHE=yes

..., 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.

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.

7f6f710bd2 imx8mq_platform_drv: introduce reset domains
A reset domain can consist of one or several reset-pins
denoted by name that are assigned to a device.
When the device gets acquired via the Platform RPC API,
the pins are de-asserted, and asserted again when the
device gets released.

A configuration looks like the following:

  <device name="mipi_dsi>
    <reset-domain name="mipi_dsi_pclk"/>
    ...

  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().

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.

2f9d430c00 base-linux: 64-bit ARM support
This patch adds support for running Genode/Linux on the AARCH64
architecture.

- The kernel-agnostic startup code (crt0) had to be extended to
  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.

0f0edc0134 usb_host: implement sg_pcopy_* as TRACE dummies
The former implementation called 'TRACE_AND_STOP' which led to the
'usb_host_drv' to stop whenever such a function was called. Rather
than stopping return '0' and let the contrib code deal with this
situation.

Issue #4116.

eb94f03416 microcode.run: do not twiddle with MAKEFLAGS
Unconditionally setting MAKEFLAGS to just 's' is not nice because other
flags cannot be passed through the run script. What the script desires
is to disable the automatically enabled '--print-directory' for sub-make
instances when calling tool/port/current by declaring
'--no-print-directory'.

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).
