This patch fixes a problem in the non-const 'for_each' method of the
'Registry' data structure. If an exception was thrown from within the
functor of the 'for_each' operation, the not yet processed items of the
registry were dropped from the registry, which is not expected.
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
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.
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
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.
- Update FatFS port from 0.07e to 0.13
- Multi-device support
- Basic test at run/fatfs
- Adaption of existing components
Note, ffat is now consistently renamed to fatfs.
Ref #2410
The new version of the test exercises the combination of fs_report with
ram_fs and fs_rom as a more flexible alternative to report_rom.
It covers two corner cases that remained unaddressed by fs_rom and
ram_fs so far: First, the late installation of a ROM-update signal
handler at fs_rom right before the content of the file is modified.
Second, the case where the requested file is not present on the file
system at the creation time of the ROM session. Here, the ram_fs missed
to inform listeners for the compound directory about the later created
file.
The input_filter is the successor of the input_merger. In addition to
merging input streams, the component applies several forms of input
transformations such as the application of keyboard layouts.
Issue #2264
This test reproduces an issue of the VFS block file system when the
underlying block device has a coarser granularity than the block
requests issued by the VFS client. I.e., if the underlying block device
has a block size of 4K, writing a sequence of (non-4K-aligned) 512 blocks
that crosss a 4K boundary corrupts the data on the block device.

Parse ``<env key="..." value=".."/>`` nodes from the config ROM and

Prepared for internal test machine, which has 8 logical cores.
6 Win7 64bit VMs are started, each having 2 vCPUs, using the same image and
different overlays. Changes to the VM are written to the overlays of ram_fs
and dropped after the test.

When run with the '--autopilot' run option, the 'usb_hid.run' script tests
the input events generated by a 'Pro Micro' microcontroller board. Setup
instructions for the Pro Micro can be found in the run script.
Fixes#2087
A run script to demonstrate the combination of the cpu_sampler, fs_log,
ram_fs and noux components for saving the sampled data in files and
accessing these in a Noux environment. When the script is run by the
autopilot, it will check if one of the generated sample data files
contains the correct instruction pointer. When the script is run
interactively, the generated files can be accessed from a Noux Bash shell.

Issue #2060
This patch revives our ds_ownership test from 2012, which just revealed
a regression in core where the dataspace-free operation of the RAM
service would unconditionally destroy dataspace objects from foreign
sessions. The patch fixes the bug and adds an updated version of the
test to the autopilot.
Fixes#2065
The main feature for this version upgrade is the use of the instruction
emulator (IEM) to speed up execution and less often the slow recompiler.
issue #2059
The commit consumes the argument of a unsupported printf command.
Without the commit - a subsequent command uses the argument of the preceding
command, which may cause memory corruption or page faults for sequences using
string commands, e.g.
Genode::printf("%#x %s\n", 0x20, "Test");
'#' is not supported by Genode::printf. In this scenario a pagefault at
address 0x20 is caused.
Fixes#1701
If a requested report already exists the request is denied with
Invalid_args.
Further, I dusted the report_rom test and added it to the
autopilot list.
Physical CPU quota was previously given to a thread on construction only
by directly specifying a percentage of the quota of the according CPU
session. Now, a new thread is given a weighting that can be any value.
The physical counter-value of such a weighting depends on the weightings
of the other threads at the CPU session. Thus, the physical quota of all
threads of a CPU session must be updated when a weighting is added or
removed. This is each time the session creates or destroys a thread.
This commit also adapts the "cpu_quota" test in base-hw accordingly.

For further information see: http://wiki.netbsd.org/rumpkernel/. In this version
I ported the central rump components to Genode in order to take advantage of
NetBSD file system implementation. The new 'dde_rump' repository contains the
Genode version of the rump libraries and a 'rump_fs' server that implements
Genode file-system-session interface. Currently ext2, iso9660, and fat
file-systems are supported.
Issue #1048
This block cache component acts as a block device for a single client.
It uses fixed 4K blocks as caching granularity, thereby implicitly reads
ahead whenever a client requests lesser amount of blocks. Currently,
it only supports a least-recently-used replacement policy.
