The file may also be changed by other components, so a open-close cycle
for write() is more robust. For example, Vim removes the original file
and recreates with the new content.
This component creates a GPT on a Block device. It supports the common
actions, as in adding, deleting and modifying entries in the GPT, while
considering alignment constraints. If needed it will round the length of
a partition down to meet those constraints. The component will not
perform layout checking, i.e., it does not care about overlapping
partitions. Only when apping a partition it will make sure that the
partition will fit.
Please read _repos/gems/src/app/gpt_write/README_ for more detailed
information on how to use the component and feel free to check out
_repos/gems/run/gpt_write.run_.
Fixes#2814.
The box-layout widget used to trigger the geometry animation of its
children immediately when updating the widget from the XML model (by
calling 'child->Widget::geometry'). This caused layout inconsistencies
in situations where the box layout is defined not by the constraints of
the child widgets but from the outside (the parent calls Widget::size).
Since the final layout is not known before the parent defines the actual
size, this patch moves the trigger point for the geometry animation to
'Widget::size'.
The new 'version' attribute can be used to explicitly distinguish
widgets that have the same name. E.g., if one widget is removed and
another with the same name is created somewhere else at the same time,
the menu view would normally interpret this change as a movement.
By attaching a distinct 'version' the new instance, menu view won't
attempt perform a smooth transition between the old and new widgets.
The '_active_mode' must not be changed at any time except when the
client asks for the 'Framebuffer::mode'. Otherwise, the dimensions of
dataspace used by the client is not always consistent with the mode
information as gathered by the client.
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
Generic code that operates over both UDP and TCP sockets might use
'sendto', but in the case of TCP the destination address ought to be
safely discarded. This seems to be the case for certain DNS software
that operates over both UDP and TCP.
Fix#2807
On real hardware, the tests expect an IPv4 subnet such that UDP requests
to 10.0.0.2 port 12345 get answered with an ICMP destination port unreachable.

Set DHCP discover timeout to 1 second because, for some reason, the first
DHCP discover attempt of the NIC router on the PandaBoard times out with the
nightly test infrastructure.

Adaption to mac-address allocation changes
Normally, the NIC sessions are independent from the domain tags.
However, by now the uplink session, in contrast to the sessions of the
other domains, is still not a server but a client. This means that only
the NIC router itself can decide when to open and close uplink sessions
and how many. Thus, with this commit, we break with the pattern that
session lifetime is independent from domains by letting the NIC router
create the uplink session when the uplink domain appears and close the
session when the domain disappears.
Fixes#2795
Since the router MAC is allocated like the donwlink MACs it can't happen
anymore that these MACs clash, for instance due to nested routers. Thus,
the range of the MAC allocators of nested routers must not be exclusive
anymore which deprecates the 'mac_first' configuration attribute.
Issue #2795
Allocate a virtual MAC address at runtime that is used as router
Ethernet-identity for all downlink domains. This makes the downlink
domains independent from the uplink session.
Issue #2795
The old MAC allocator had several drawbacks:
* the address base was a public static that could and must have been written
directly from outside the class
* the in-use-flag array was based on unsigned values consuming 4 bytes each
for only one bit of information
* it was a public header that we actually don't want to expose to all
components but only to the few networking components
* it used the not-so-safe bit notation for integer members of GCC
The new version fixes all these drawbacks.
Issue #2795
Instead of handing over the maximum available size to the packet data
accessors, hand over a size guard that keeps track of the packets
boundaries.
This commit also moves the size-guard utilitiy header of Ping and NIC
Router to the include/net directory making it a part of the net library.
It applies the new approach to all net-lib users in the basic repositories.
Ping looses its configurability regarding the ICMP data size as this would
require an additional method in the size guard which would be used only by
Ping.
The size guard was also re-worked to fit the fact that a packet can
bring a tail as well as a header (Ethernet).
Issue #2788
For now it is enough to differentiate the most commonly used file
system on Genode, e.g. Ext2 for the Genode partition and FAT32 for
(U)EFI partitions.
Issue #2803.
The component will now always try to parse the MBR as well as the GPT
(in this order). It will bail out if both are considered valid, using
GPT/MBR hybrid tables is not supported.
Fixes#2803.
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.
issue #2791
pthread_attr is not associated with any thread, the statistics must be
gathered at runtime, while 'pthread_attr_get_np' may retrieve attributes
by from any thread. Addtionally, the attributes given to
'pthread_create' will most likely be deleted after the creation call.
