This patch reintroduces the LwIP stack to libc as a VFS plugin
implementing the socket_fs interface. Rather than use LwIP's socket
emulation layer this plugin interfaces directly to LwIP raw API and is
single threaded.
The internal TCP parameters of the stack are untuned.
Fix#2050Fix#2335
This new vfs_import plugin allows a VFS instance to be populated during
construction using a sub-VFS configured in an '<import>' configuration
node. This allows the ram_fs File_system server to be replaced by the
VFS server by reimplementing the ram_fs 'content' feature. At the
moment the copying of symlinks is not enabled, and the resources
obtained by the import file-system may not be freed after the import is
finished.
Fix#2906
Test of File_system I/O scheduling. It appears that a client not
submitting I/O packets slower than the VFS server can process will
starve other clients.
Ref #2900
Also remove 'requires_installation_of', while also checking sbin
directories in 'have_installed'. The run scripts have been adjusted
accordingly.
Fixes#2853
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.
Issue #2857
This test monitors the RAM quota of a dynamic init and a server hosted
within the dynamic init in the presence of a repeatedly created and
destructed client.
Newer revisions of parted require special privileges due to use of the
dmidecode tool, which logs permission errors to standard error. In these
cases parted still succeeds with its operation, so just ignore the
jabbering and prevent expect to exit.
Unfortunately, some sites do not support the HTTP/1.1 range header and
just serve the whole file, which takes it's time and may result in a
timeout.
Fixes#2819
Issue #2778
The "create_grub2" script functionality is moved to the g2fg contrib sources
and also the GRUB2 head image (tool/grub2-head.img). The head image is now
partitioned as GPT and bootable in BIOS legacy mode.
The nic_bridge test is not suitable to be executed on hardware so it should,
in case, print an appropriate message and return without doing anything else.
Issue #2788
Our nightly did not detect the current stale hashes because only updated
(in the sense of a changed hash) ports are prepared. Others were left
untouched besides the check_port_source step. Now, check_hash also
checks for missing hash file updates.
SHA1 is susceptible to collision attacks and is generally deprecated.
Source code archives are particularly vulnerable because the hash digest
can be tweaked by hiding by arbitrary data in code comments and files
not processed during build.
With this in mind the 'prepare_port' tool now attempts to verify digests
as SHA256 with a fallback to SHA1. When CHECK_HASH=no is set the tool
will refuse to verify digests as SHA1. The use of SHA1 for creating
unique port versions is retained because the hashes are produced locally
from inputs stored in a git history.
Issue #2767
This driver component provides support for using consumer NVMe storage
devices, i.e. it omits name space managment and will always use the
first name space, on Genode. For now it defaults to a reasonable low
configuration:
- 1 I/O queue (completion/submission tuple)
- 128 entries in the I/O queue
- 4096 as the only I/O transaction memory page size
Fixes#2747.
Our static okl4 system-integration configuration specifies a fixed RAM
range from 32 to 800 MiB, which must be satisfied by Qemu or strange
errors happen due to accesses beyond RAM. (Fixes current issues with
nic_router.run.)
Switch port I/O based PCI config space access to memory-mapped IO. The
base address of the PCI configuration space is acquired by mapping the
ACPI ROM and reading the first <bdf> node. An exception is thrown if the
first <bdf> node is not for PCI domain zero or if multiple <bdf> nodes
exist. This is to reduce complexity and also because multiple PCI
domains are rare.
The PCI configuration space is accessed via I/O mem dataspace which is
created in the platform_drv root and then passed on to the PCI session,
device components and finally to the actual PCI config access instances.
The memory access code is implemented in a way to make it work with Muen
subject monitor (SM) device emulation and also general x86 targets. On
Muen, the simplified device emulation code (which works also for Linux)
always returns 0xffff in EAX to indicate a non-existing device.
Therefore, EAX is enforced in the assembly templates.
Fixes#2547
When a pkg is missing, the user should create <arch>/pkg instead
of only the missing pkg. This way, all depending binaries are created in
one step. Otherwise the missing binaries are detected at the next time
the run script is executed. This patch relieves the user from iterating
manually.
This commit changes the semantic of run_boot_dir to link a core
binary with debug symbols only when the designated library is in place.
Follow-up fix refering to issues #2339 and #2700
The install_pxe_bootloader_to_run_dir procedure is required by the tftp
as well as the ipxe load script. Move it to a separate file which is
include by both.
- Use latest Muen version
- Sync VirtualBox Muen subject state
- Drop unneccessary subject IP patch
- Adapt Muen RUN_OPTs
- Update documentation
Note: the GPL 2017 toolchain is now required and as the debug output
format has changed the mulog-subject.py script must be updated on
autopilot instances.
The timestamp-based rules of make do not work well for the publish tool
because depot archives are often re-created with the same content but a
different modification time, in particular when creating archives via
'FORCE'. This way, those archives are re-published every time, which
becomes a time-consuming operation since all archives must be signed.
This patch filters the targets based on the content that is already
present in the public/ location. All existing archives are skipped.
Apply the approach to join the argument list 'args' to pass a single
list argument to _collect_from_depot. Actually, this story teaches me to
shy away from {*} because of its special semantics, which are
{*} makes each item in a list an individual argument of the current
command (https://wiki.tcl.tk/17158)
This is a direct follow up to "run: let import_from_depot accept list
variables", which broke calling import_from_depot with a number of
individual arguments.
Issue #2619
When doing something like this in a run script ...
lappend arg X
lappend arg Y
lappend arg Z
import_from_depot arg
... the internals of import_from_depot do not treat $arg as list but as one
string and interprets it as malformed depot path. We can handle this by
applying {*} to $arg inside the procedure.
Issue #2619
This patch changes the depot layout such that each archive is
represented as a directory that contains the versions of the archive as
subdirectories.
Issue #2610
The run tool now by default checks configurations with target-specific
XML schemata. Each component may define a config schema file in its
target.mk via the CONFIG_XSD variable. When the run tool has checked an
configuration of an init instance, it additionally goes through the
start nodes of the config. For each start node it checks whether there
is an XSD file that matches. If so, the run tool also checks the config
of the start node (if existant). This is done recursively. I.e., also
the child configs of a sub-init of a sub-init of the top-level init
receive a config check.
Issue #2600
In general, make the message conform to the according message of the
common build system. Adds instruction how to fix the missing/outdated
port.
Fixes#2573
If there is no debug/core-<kernel>.o library available, e.g., when
running a scenario in a fresh build directory where core is provided
via a depot package, the build_core_image step of the run tool was
canceled in the past, when trying to access the non-existing library.
This commit changes the semantic of build_core_image to link a core
binary with debug symbols only when the designated library is in place.
This fixup is related to issue #2339
* introduce new syscall (core-only) to create privileged threads
* take the privilege level of the thread into account
when doing a context switch
* map kernel segment as accessable for privileged code only
Ref #2091
* introduces central memory map for core/kernel
* on 32-bit platforms the kernel/core starts at 0x80000000
* on 64-bit platforms the kernel/core starts at 0xffffffc000000000
* mark kernel/core mappings as global ones (tagged TLB)
* move the exception vector to begin of core's binary,
thereby bootstrap knows from where to map it appropriately
* do not map boot modules into core anymore
* constrain core's virtual heap memory area
* differentiate in between user's and core's main thread's UTCB,
which now resides inside the kernel segment
Ref #2091
In the image.elf file, the very last boot module is followed
by arbitrary other core-local data. Since those boot modules are
exported as page-granular dataspace to the outside of core via core's
ROM service, we need to ensure that the last page is padded with zeros.
