If the suspend method for the main thread detects that the suspend
condition is false it must return the passed timeout value (not always
0). Otherwise, the caller may incorrectly assume the timeout expired.
Especially the initial reset ended up with an unusable keyboard in rare
cases before. This commit disables keyboard and mouse handling of i8042
during command sequences according to a note from
https://www.win.tue.nl/~aeb/linux/kbd/scancodes-12.html
The new utility can be used to revert quoted XML attribute values.
Such quoting is needed whenever an attribute value can contain '"'
characters. E.g., in the menu_view's <label text="..."> widget.
Issue #1757
If the ROM service returned in invalid dataspace, reflect this condition
via a size of zero instead of triggering an exception of type
'Reconstructible<Attached_dataspace>::Deref_unconstructed_object'.
Issue #3606
An invalid ROM dataspace can occur, for example, when requesting a ROM
from the report_rom service before the first report was posted. Such a
<rom> node can still be useful if it's dynamic. E.g., it can be watched.
Hence, the corner case of an invalid ROM dataspace should be gracefully
handled instead of causing an abort.
Issue #3606
This patch adds a special variant of a 'Content_producer' called
'Xml_producer', which allows the direct use of an 'Xml_generator'
for generating the ROM-module content.
This patch extracts the child-management functionality from the init
component into a new library called "sandbox". The library API is
located at 'os/include/os/sandbox.h'.
The sandbox API allows for the interaction of the component with the
sandboxed children by providing locally implemented services. This
mechanism is illustrated by the new test at os/src/test/sandbox.
Issue #3601
This patch extends the 'Buffered_xml' utility with a new constructor
that fills the buffer with the output of an 'Xml_generator'. It thereby
presents an easy way to generate XML to be consumed locally.
The patch also add a deprecation mark to the original 'xml' accessor
because copying 'Xml_node' objects (here as return value) is dangerous.
The new 'with_xml_node' method should instead be used to access the XML
content stored in the buffer.
Fixes#3602
The XML parser used to rely in C++ exceptions while parsing, which is an
artifact from the initial implementation. This patch reworks the code such
that exceptions are avoided in the common cases.
Fixes#3605
Replace return values with appropiate bool and document two-staged
publickey authentication. This fixes a bug where wrong authentication
attempts are not properly denied.
Issue #3590.
Adding an explicit check clarifies at the first glance that the array
bounds are respected without needing knowledge about MAX_CAPS_PER_MSG
and L4_UTCB_GENERIC_DATA_SIZE (used for dimensioning 'mr').
This patch changes the code of '_alloc_two_blocks_metadata' to not
leak the result of a partial allocation in the out parameters of
the method. This eases the reasoning about the absence of a
use-atfer-free problem (there was none).
