This patch adds support for watch notifications for the
'Readonly_value_file_system', which is often used by VFS plugins to
implement pseudo files. It thereby enables VFS clients to respond to
VFS-plugin events (think of terminal resize) dynamically.
Fixes#3523
As genode.org site is now protected by TLS and unencrypted site
is redirected to enctypted one, download URL should be modified
to reflect this change.
Without this change, wget downloads just index.html file.

It runs pretty well on Raspberry Pi, for example.
Leaving this scenario limited to x86 for autopilot runs only.

Fixes#3536
Prevents integration failures like follows if the libraries were not
built already in the build directory.
Missing boot modules: libm.lib.so posix.lib.so
Makefile:323: recipe for target 'run/lwip_lx' failed
Passing array of unsigned chars to Genode::log() function
makes it converted to void pointer, resulting in printing its address.
Wrapping this array into Genode::Cstring solves this problem
and makes it being printed properly as zero-terminaled string.

Fixes#3530
Uplink labels were stored in the uplink objects as reference. As uplink objects
may be re-used on re-configuration to avoid unnecessary closing and re-opening
of NIC sessions, the label reference could get invalid as the object that
stored the label content didn't get re-used. Thus, the label is now copied to
the uplink object.
Fixes#3529
This adds two new boolean attributes to the <report> tag of the NIC router
configuration 'link_state' and 'link_state_triggers'. The former decides
whether to report the link state of each NIC interface (downlink, uplinks) at
the NIC router. The other decides whether to trigger reporting each time the
link state of an interface changes.
Fixes#3527
If a MAC address was once allocated for a downlink and during the further
creation of the downlink an exception caused the creation to be aborted, the
NIC router didn't free the MAC address again.
Ref #3525
The handling of exceptions during session creation implies freeing and
detaching the RAM DS behind the session env and session component. But this
was done using the session env located in the same RAM DS, which must
lead to problems. Now, the session env from the RAM DS is copied to the stack
and the operations are done on this temporary instance instead.
Ref #3525
When the construction of a member of Packet_stream_*::Rpc_object after
the _cap member threw an exception, the object was not dissolved from
the entrypoint although the Rpc_object vanished at this point. This was
because the call to 'manage()' happened in the initializer list (for the
_cap member instantiation). The destruction of the _cap member then did
not dissolve the object.
This first fix moves the call to 'manage()' into the constructor body
after the instantiation of all other members. A more sophisticated fix
would use some kind of 'Managed_object' life-time guard that manages an
object on construction and dissolves on destruction.
Ref #3525
When re-configuring a domain from using a static IP config to using a dynamic
IP config, attached interfaces didn't react with doing DHCP discover. This bug
is fixed now and the nic_router_flood test was adapted in a way that it tests
the described behavior.
Fix#3518
This patch introduces a new scheme of handling ioctl operations that
maps ioctls to pseudo-file accesses, similar to how the libc maps socket
calls to socket-fs operations.
A device file can be accompanied with a (hidden) directory that is named
after the device file and hosts pseudo files for triggering the various
device operations. For example, for accessing a terminal, the directory
structure looks like this:
/dev/terminal
/dev/.terminal/info
The 'info' file contains device information in XML format. The type of
the XML node corresponds to the device type. E.g., If the libc receives
a 'TIOCGWINSZ' ioctl for /dev/terminal, it reads the content of
/dev/.terminal/info to obtain the terminal-size information. In this
case, the 'info' file looks as follows:
<terminal rows="25" columns="80/>
Following this scheme, VFS plugins can support ioctl operations by
providing an ioctl directory in addition to the actual device file.
Internally, the mechanism uses the 'os/vfs.h' API to access pseudo
files. Hence, we need to propagate the Vfs::Env to 'vfs_plugin.cc' to
create an instance of a 'Directory' for the root for the VFS.
Issue #3519
The run script used to be the only user of the fatfs_fs server, which
we're going to remove. This patch removes the components for accessing a
real storage device and file system from the run script. The new version
just uses ram_fs.
Issue #3512
Nowadays, we use standard command-line tools like vim to edit init
configurations dynamically, which alleviates the need for a custom CLI.
The CLI-monitor component was too limited for use cases like Sculpt
anyway.
The patch also removes the ancient (and untested for long time)
terminal_mux.run script, which used to be the only remaining user of the
CLI monitor.
Issue #3512
This driver manually checks if the RAM quota is big enough for the
Lan9118 nic session component. The problem is Root_component::_create
from which Root_component::_create_session gets called does already
check this. No need to account for it twice.
Fixes#3514
This patch extends the 'File_system::Status',
'File_system::Directory_entry', and the related 'Vfs' types with
the following additional information:
- Distinction between continuous and transactional files (Node_type)
(issue #3507)
- Readable, writeable, and executable attributes (Node_rwx),
replacing the former 'mode' bits
(issue #3030)
The types 'Node_rwx', 'Node_type' are defined twice,
once for the VFS (vfs/types.h) and once for the 'File_system'
session (file_system_session/file_system_session.h).
Similarly, there is a direct correspondance between
'Vfs::Directory_service::Dirent' and 'File_system::Directory_entry'.
This duplication of types follows the existing pattern of keeping the
VFS and file-system session independent from each other.
