This patch avoids the repeated warning "read blocked until lwIP
interface is ready" by printing the message only once. Otherwise,
the log is flooded with those warnings when falkon web browser
is started on Sculpt OS without network connectivity.
The vfs pipe plugin can now be used as named pipe which anables data
transfer via file handles from one component to another. E.g. if one
would like to send data from component A to stdin of a libc component B,
one can do so by simply writing to that fifo file.
Issue #3583
With this commit libcrypto does not use ARM NEON extension as long as
SPECS includes "neon". arm_v7a does declare "neon" per default while
arm_v8a does.
Issue #3773
Note, OpenSSL now comes as one combined depot archive *openssl* that
replaces the former *libssl* and *libcrypto* archives. The libraries are
still separate binaries for compatibility with legacy software.
Issue #3773
Be more in line with the original host implementation in Qemu and
buffer transfers. Having transfers in-flight helps to smoothen playback
in case other components utilize the CPU.
Issue #4018.
Linux as well as Windows guests want queue to a varying number of
transfers, where each transfer only covers one transaction (iso frame).
The best results were obtained by following that behaviour rather
than queuing multiple iso frames per requests (like is done with OUT
transfers).
The number of requests queued is increased to 32 while the number of
packets per reques is decreased to 1.
Issue #4018.
The contrib code is updated from 2.4.1 to version 5.2.0 and the used
device-model is changed to QEMU xHCI. Due to this change older guests
OSes, namely Windows 7, that relied on the NEC xHCI device-model will
not work anymore.
The 'Qemu::Controller' interface was extended by an 'info' method, which
returns the vendor and product ID. This allows for removing the
hard-coded values in the VirtualBox glue code.
Issue #4018.
The former implemention assumed that the guest physical memory is
mapped continously. This, however, is not true. Writing larger
files to an USB stick with a Windows 10 guest would therefore lead
to data corruption.
The current implementation uses a bounce buffer to copy the data
to and from the guest physical memory and leaves dealing with the
memory mappings entirely up to the VMM.
Fixes#4017.
The 'environ' pointer is a global variable that must be considered as
part of the application state. It must be copied from the parent to the
child process during fork. Otherwise, a child returning from fork is
unable to access environment variables before invoking execve. The
actual environment variables and their values are already captured
because they reside at the application heap, which is cloned from the
parent. So the copied 'environ' pointer refers to valid data.
Fixes#4015
The _dispatch_pending_io_signals and _original_suspended_callback member
variables are not used anywhere in the code. This prompts clang to produce
a warning message about it. Remove both variables to fix it.
Issue #3985
GCC doesn't care, but clang complains if [[fallthrough]] is not followed
by a semicolon. Existing Genode code is also not consitent in this regard.
This patch adds the extra semicolons since it works in both GCC and
clang.
Issue #3985
The class has final destructor, but is not itself final. This prompts
clang to produce the following warning message:
class with destructor marked 'final' cannot be inherited from [-Wfinal-dtor-non-final-class]
~Vfs_plugin() final { }
^
vfs_plugin.h:39:13: note: mark 'Libc::Vfs_plugin' as 'final' to silence this warning
Issue #3985
This static inline function is not used anywhere. GCC does not care,
but clang warns about this. Remove the function to allow the code to
compile cleanly with both clang and GCC.
Issue #3985
The code in Libc::Cloned_malloc_heap_range initializes its local_addr
member variable by calling Region_map::attach_at. This function can
throw Region_conflict exception. The handler for this exception uses the
local_addr to produce an error message. Such error log is IHMO
useless, or even incorrect since the value of local_addr is undefined
in such case.
Its also worth noting that clang 12 produces the following warning for
this code:
"cannot refer to a non-static member from the handler of a constructor
function try block"
Issue #3985
If a fd is opened in append mode and just is to be used (so never written by
the parent component) for the to be forked child, the seek state was not
pointing to the end of the file. The wrong seek value then was used in
File_descriptor_allocator::generate_info().
Issue #3991
The fds in O_APPEND state may have changed by the child. The local seek
state needs to be valid/current for the next to be forked child, which seek
state is set by File_descriptor_allocator::generate_info().
Issue #3991
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
Let the NIC router provide an Uplink service besides the Nic service that it
already provided. Requests for an Uplink session towards the NIC router are
assigned to Domains using the same <policy> configuration tags that are used in
order to assign Nic session requests. The MAC addresses of Uplink session
components are _NOT_ considered during the allocation of MAC addresses for NIC
session components at the same Domain. The task of avoiding MAC address clashes
between Uplink session components and Nic session components is therefore left
to the integrator. Apart from that, Uplink session components are treated by
the NIC router like any other interface.
Ref #3961
The keys, mute, touchpad toggle (Fn-F4) and rfkill may be reported by some
Fujitsu machines via the ACPI FUJ02E3 ACPI device. With this commit limited
support to detect the 3 keys are added and will be reported as Genode report.
