At least on x86_64/x86_64/pc/hw|nova, the test used to fail because the net
setup sometimes required more than the 3 seconds that the test was giving each
step. This commit raises the step timeout to 5 seconds and the test timeout
from 70 to 90 seconds in order to be on the safe side.
Ref #5192
This commits updates the contrib sources to version 8.7.1.
This version requires more random entropy as it queries OpenSSL
about the current random state and will bail if it is not sufficient.
Doubling the content of the '<inline>' VFS plugin as used in static
configurations seems satisfactory.
Furthermore DNS resolving needs a configured '<pipe>' plugin to work
properly.
Fixes#5184.
Commit 'wifi_drv: re-arm scan timer when enabled again' allowed for
re-arming the scan timer but still uses the old timer value the first
time around. If the timer was disabled, by setting the interval to 0,
it was not enabled again.
We now check if the interval has changed beforehand and potentially
arm the scan timer afterwards.
Fixes#5178.
Because all operations in lxip are non-blocking, return
WRITE_ERR_WOULD_BLOCK for data writes as done by read.
Note: This was not the case in the old plugin because 'write' was blocking
operation there.
issue #5165
Rarely. it might happen that events got received shortly before the complete
set of relevant USB devices got recognized. Filter more output in test metric
to stay robust.
All errors (as in the legacy version) are now propagated as WRITE_ERR_IO
(see Lxip_vfs_file_handle::write), which ultimately will lead to EPIPE
in libc's socket_fs. This also counts for EAGAIN leading to the fact
that partial writes are not supported for blocking sockets in libc, also
libc will not try a second time in case not all data has been written.
issue #5165
The IP stack checks "user" pointer access, for example, for iov's using
'access_ok' which in turn calls '__access_ok'. The function checks if the
pointer is below TASK_SIZE_MAX, which is usually a big value on 64 bit
systems, but 3GB on 32 bit systems. Because the IP stack is mostly used with
Genode's libc, where pointers on some kernels (base-linux) can be >3GB and we
don't want to make an additional copy of each buffer/iov interacting with the
IP stack, we short circuit the function
issue #5165
pci_channel_offline() checks if this member is set to
pci_channel_io_normal (which is 1). The former value of 0 is invalid.
This change fixes pc_nic_drv link down-up in cases that require an e1000
reset.
lx_emul_trace_msg() uses Genode::trace() as message function for
lightweight trace points, but also supports Linux format-string
attributes by using vsnprintf().
This is function gets called by some libssh applications using vms_lxip.
For the dummy implementation I looked at the old port.

Issue gapfruit#1976
The added hook 'OBJ_POSTPROC_SRC' gives us a way to post-process object
files for generating supplemental code. By using this hook, the
initcall_table.c generated by import-lx_emul_common.inc gets reliably
executed after all object files are built.
Fixes#5159
The option is used during the generation of initcall_table.c.
However, it happens to strip the first argument following the option.
The long option --defined-only works as expected.
Issue #5155
Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.
The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.
The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.
This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.
The adaptations necessary target the following areas:
* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
with the new policy rules of the USB host controller driver
Fixgenodelabs/genode#5021
Newer Qemu variants quit with an error about already existing devices
if the same device-id is add and removed in a loop fast. To circumvent
this strange behaviour, simply use consecutive device id numbers.
Ref genodelabs/genode#5021
A read with MSG_PEEK returns -1 and EGAIN/EWOULDBLOCK in case the socket
is connected. Zero is only returned if the socket is disconnected.
isuee #5104
The key element of the improvement is differentiated processing of
events of the following device types.
Mouse: relative motion
Pointer: absolute motion (Qemu usb-tablet and IP-KVM devices)
Touchpad: relative motion via absolute touchpad coordinates
Touchtool: absolute motion (e.g., stylus)
Touchscreen: absolute motion and finger (multi-) touch
Processing is done in two stages for one "input packet". First, all
events of the packet are recorded into the current evdev state with
device-type specific operations. Then, appropriate Genode input events
are generated from the accumulated evdev state in the submission stage
(again by device-type specific functions).
A simple version of tap-to-click was added to the touchpad support.
Fixes#5105
This commit enables generic Linux multi-touch support as well as support
for the Wacom Intuos/Graphire tablets as found in the previous version
of the USB HID driver. Events are not properly propagated through
Genode's Event C-API, yet, which will be a follow up.
Issue #5105
When SMP is enabled multicore specific instructions (e.g., pldw) are
generated. These are not supported and lead to invalid instruction
faults on uni-processor systems (like Cortex-A8). Therefore, we disable
SMP for arm_v7 in Linux code. This requires also a switch from the RCU
tree implementation to RCU tiny, which we shadow and dummy implemented.
issue #5104
Until now, in case 'jent_entropy_init' failed an error has been produced
and the following jitterentropy functions (i.e.,
'jent_entropy_collector_alloc') where called nevertheless. In case we
received a bad time source error, for example because the performance
counters are not working on the platform, the entropy collector did not return (endless
loop).
Therefore, this commit treats the failed jitterentropy initialization
not as an error but prints a warning about poor randomness quality and
stops using the jitterentropy library from this point on. The
'Jitterentropy::gen_random_u64' will in this case return the address of
a stack variable * some counter.
This is only a interim solution to make platforms work where performance
counters or TSC values do not exist/work.
issue #5104
Adjust the plugin to use the socket C-API found under
dde_linux/src/lib/lxip/include/genode_c_api/socket.h'.
This is the first minor step in generalizing the plugin.
isse #5104
The lxip_raw.run script will spawn a client/server scenario that tests
Genode C-API calls. The scenario can be used standalone, meaning no
actual network card is required.
issue #5104
This commit updates lxip from version 4.4.3 to 6.1.20. It uses the
current lx_kit approach and is a shared library again. The stack has
been tested for x86_32/x86_64/arm_v6/arm_v7/arm_8.
The C-interface of the IP stack can be found under
lxip/include/genode_c_api/socket.h.
issue #5104
CONFIG_X86_USE_PPRO_CHECKSUM is a 'def_bool y' and gets re-enabled by
'make olddefconfig'. The PPRO version contains text relocations which we cannot
have in binaries (e.g., 'lea 45f(%ebx ...).').
