Currently, LxIP peers need a lot of RAM (the simple test-client/server for the
nic_router test need at least 28 MB per component). As the nic_router test
previously used 6 instances of such components and a lot of other components,
it had issues with insufficient RAM on some platforms. By using two new
LwIP-based UDP tests instead, we save more than 100 MB.

Check at the VFS server that the capability cost of sessions do not
exceed the session quota donation. Raise the default initial capability
donation for File_system connections.
Fix#2553
Instead of storing whether the first item in the timeout list was already
programmed using the timer service, just program the first timeout in the
list unconditionally. In the past we lost a timeout at least when using the
usb ethernet driver on hw/arndale sporadically.
Previously the destructors of classes derived from Source were not
called when destructing a Source because Source missed the declaration
of a virtual destructor. This caused at least problems when
reconstructing a Chargen_source with its Chargen_repeater that includes
a One_shot_timeout. In this case, the members of the Alarm behind the
timeout were not reset and the next time beeing used the Alarm appeared
to be still active which wasn't true.
Fixes#2570
Instead of changing the attributes (e.g., Xd bit) of the top-level page-tables,
set them to allow everything. Only leafs of the paging hierarchy are set
according to the paging attributes given by core. Otherwise, top-level page-
table attributes are changed during lifetime, which requires a TLB flush
operation (not intended in the semantic of the kernel/core).
This led to problems when using the non-executable features introduced by
issue #1723 in the recent past.
The dependency was added as a supposed work-around of a dysfunctional
fork when building bash as depot archive. However, it turned out that
the actual problem was related to the timestamps of 3rd-party source
file, which were discarded by the recipes/src/bash/content.mk.
A new configuration may implicitly change the domain color of the
currently focused session. We need to refresh the report to trigger an
update of the status bar.
This commit replaces the old xray_trigger component by a new component
called global_keys_handler. For details, please refer to the issue text
and the accompanied README file.
Fixes#2554
Without this patch, usb_drv would issue a resource request when
assigning a USB device to a VM in the sculpt scenario.
Furthermore, the patch adjusts the intel_fb quota to enable it on
devices where the driver allocates the framebuffer in many 4K pieces.
Linux does not do that in register_netdev() either. Some drivers set the
carrier flags on attach and never reenable it (as seen with rndis_host).
Consequently, the usbnet driver refuses to receive data as it checks the
carrier state before enqueuing new SKBs to its receive queue.
Apart from rndis_host, this change was tested with an ax88179_178a
device which worked as expected.
Whenever a childs is terminated the exit value is propagate through a
new state report. Thereby it becomes possibly for a managing component
to react upon the terminating condition of a child.
Issue #2558.
Until now the client called the Linux code directly through the EP
when sending ethernet frames and was not part of the driver's internal
task scheduling. This will lead to problems if the sending code needs
to grab a lock as those depend on running from within a Lx::Task.
Although this has only happend recently when using 8260 devices, this
is an issue that needs to be fix.
This commit addresses the issue by using a dedicated transmit task
in whose context the Linux code sends the ethernet frame or rather
newly allocated skb.
Fixes#2559.
As noted above the former enum for the local-attachment address we
discovered address clashes on current Linux installations, esp. 32-bit
runtime on 64-bit Linux. The local_attach_addr is now configurable in
the run script and the memory maps heuristics were removed.
Recent work related to issue 1723 showed that there is potential
to get rid of code duplication in MMU fault handling especially
with regard to ARM cpus.
If the attribute 'interface' is not set in a 'domain' tag, the router tries to
dynamically receive and maintain an IP configuration for that domain by using
DHCP in the client role at all interfaces that connect to the domain. In the
DHCP discover phase, the router simply chooses the first DHCP offer that
arrives. So, no comparison of different DHCP offers is done. In the DHCP
request phase, the server is expected to provide an IP address, a gateway, a
subnet mask, and an IP lease time to the router. If anything substantial goes
wrong during a DHCP exchange, the router discards the outcome of the exchange
and goes back to the DHCP discover phase. At any time where there is no valid
IP configuration present at a domain, the domain does only act as DHCP client
and all other router functionality is disabled for the domain. A domain cannot
act as DHCP client and DHCP server at once. So, a 'domain' tag must either
have an 'interface' attribute or must not contain a 'dhcp-server' tag.
Ref #2534
An IPv4 config (for a domain/interface of the router) consists of
an IPv4 address, a subnet prefix specifier, an optional gateway
IPv4 address, and some flags that declare whether these fields and
the config as a whole are valid. To make the handling of those
tightly connected values easier and less error prone, we encapsulate
them in a new class.
Ref #2534
Under certain circumstances we don't want inits state report to become too
outdated even if there is no change to its config or the sessions of its
children. This is the case if init is requested to provide a capability or RAM
info of it's children via its state report. Now, init automatically updates
the state report with each 1000 ms if the attribute 'child_caps' or
'child_ram' is positively set in the 'report' tag.
The tools.conf in base-fiasco/etc was obsolete and must therefore not
packaged.
This commit removes sporadic recipe hash changes due to missing or
existent etc/tools.conf.
