It can happen that a keyboard gets plugged in and 'led_connect()' is
called while the keyboard LED of another keyboard is just being updated
(and the registry is locked).
Fixes#3118
The Linux emulation library provides preprocessor macros for min() and
max(), which now clash with implementation in duration.h. So, we disable
those macros in the delay implementation.
Some application code is dereferencing the pointer returned by
'packet_content' at packet streams without checking that it is valid.
Throw an exception rather than return a null pointer, except for
zero-length packets, which have somewhat implicit invalid content and
that we believe to be properly handled in all current cases.
The client-side of a packet stream cannot take corrective action if the
server-side is sending packets with invalid content, but the servers
that provide packet streams should catch this exception to detect
misbehaving clients.
Ref #3059
Move button-event reporting behind pointer-position update.
This is just a quickfix to restore correct pointer emulation with
dde_linux usb_drv. It does not change usb_hid_drv because the approach
is a questionable workaround of the current input event handling, which
reports events promptly on occurrence of inputs events and ignores
synchronization events completely. The original contrib code reported
the button press before absolute x and y positioning followed by a sync
event.
Issue #3019
The tasklet_schedule implementation was missing the unblock call, which
was no problem in the past because the correspending task would get un-
blocked by other work items. Now that every workqueue has its own task,
there is nobody left to unblock the task and thereby execute the
tasklet. As a tasklet is the only way to transmit any pending frames
after transmission was temporarily suspended - because the device/fw
was not able to process the TX request - this rendered 6xxx devices
unusable whenever this situation occurred.
Fixes#2973.
The libc sockets implementation already syncs socket control files after
writes, so sync errors will induce failures for operations such as
"connect".
Fix#2920
It can happen that a keyboard gets plugged in and 'led_connect()' is
called while the keyboard LED of another keyboard is just being updated
(and the registry is locked).
Fixes#2869
Socket_fs sockets are now created each time a 'new_socket' control file
is opened, not each time a 'new_socket' file is read. When a handle on a
'new_socket' file is closed the socket and its socket files are
destroyed. The accept control file on a listening socket reads "1" or
reads nothing to indicate a client connection is queued. Client sockets
are accepted by opening an 'accept_socket' file in the listen socket
directory. This file behaves like the aforementioned 'new_socket' file.

This commit changes the 'Input::Event' type to be more safe and to
deliver symbolic character information along with press events.
Issue #2761Fixes#2786
Reduce the size and forward compatibility of VFS file-system
constructors by passing an object holding accessors for 'Genode::Env',
'Genode::Allocator', response handlers, and the root file-system.
Fix#2742
This patch enables the use of the VFS from VFS plugins by passing a
reference of the root directory to the constructors of file-system
instances. Since it changes the signature of 'Vfs::Dir_file_system',
any code that uses the VFS directly requires an adaptation.
Fixes#2701
Aligning memory to page size will require at lead 8KB per allocation (even for 8
bytes). This should severely reduce memory requirements of all dde_linux
projects.
