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.
Issue #2262
Parse ``<env key="..." value=".."/>`` nodes from the config ROM and
populate a list at the 'genode_envp' and 'environ' symbols.
Test script at run/libc_getenv.
Fix#2236
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.
