Linux del_timer() and mod_timer() return if the timer was pending before
the modification. Additionally, these functions are potentially called
from handler function of the timer to modify and, therefore, checking
for timeout != INVALID_TIMEOUT is not sufficient as the timeout is
indeed valid when the handler is executed.
In the image.elf file, the very last boot module is followed
by arbitrary other core-local data. Since those boot modules are
exported as page-granular dataspace to the outside of core via core's
ROM service, we need to ensure that the last page is padded with zeros.
This patch fixes an aliasing problem of the 'close' method signature
that prevented the Input::Root_component::close method to be called.
This way, the event-queue state was not reset at session-close time,
which prevented a subsequent session-creation request to succeed. With
the patch, input servers like ps2_drv, usb_drv that rely on the
Input::Root_component support the dynamic re-opening of sessions. This
happens in particular when using a dynamically configured input filter.
We update the alarm-scheduler time with results of
Timer::Connection::curr_time when we schedule new timeouts but when
handling the signal from the Timer server we updated the alarm-scheduler
time with the result of Timer::Connection::elapsed_us. Mixing times
like this could cause a non-monotone time value in the alarm scheduler.
The alarm scheduler then thought that the time value wrapped and
triggered all timeouts immediately. The problem was fixed by always
using Timer::Connection::curr_time as time source.

This recipe copies the entire stdcxx library into the API archive, which
is an interim solution until we introduce a proper ABI for stdcxx. With
this current version, every user of the stdcxx ABI will implicitly build
the stdcxx library.
This patch merges two similar rules, which create content at 'include'
into a single rule. This prevents a possible race condition when
creating archives in parallel.
We moved the stack-area segment 128 MiB behind text and data to comply
with assumptions in the kernel ELF loader.
This commit also reenables static binaries on linux and removes the
unused stack_area.stdlib.ld script.
Fixes#2521
This is a drivers subsystem that starts the most fundamental
(framebuffer, input, block) device drivers dynamically, depending on the
runtime-detected devices. The discovered block devices are reported
as a "block_devices" report.
This patch applies the handling of cursor keys, function keys, and page
up/down keys even if no keymap is defined. This is the case when using
the terminal with character events produced by the input filter.
This patch is a workaround for the apparent problem that noux
applications, which perform execve, implicitly use functionality from
the dynamic linker, not explicitly via the libc. If the binary lacks the
dependency information, noux will fail on the execve attempt. The latter
is the case when the noux package is built as a depot archive where
library dependencies are not traversed over multiple levels.
In nested scenarios like driver_manager.run, the initial session quota
for IO_PORT, IO_PORT, and IRQ sessions is expectedly insufficient.
However, the condition is properly handled by re-attemping the request
with a slightly increased quota. Still, core prints a warning each time
the request is denied for quota reasons, which spams the log. This patch
removes the non-critical message.
Create periodic and one-shot timeouts with the maximum duration
to see if triggers any corner-case bugs. They must not trigger during
the test.
