This compilation unit contains a global constructor, which violates our
assumption that the libc is free of global constructors on ARMv7.
Specifically, the graphical terminal fails with the following message:
[init -> terminal] Error: Component::construct() returned without executing
pending static constructors (fix by calling
Genode::Env::exec_static_constructors())
[init -> terminal] Error: Uncaught exception of type 'Linker::Fatal'
In this case, the libc-less terminal uses the VFS. The VFS mounts the
ttf VFS plugin. The ttf VFS plugin depends on the libc.
The compilation unit 'arm_initfini.c' can safely be excluded because it
merely initializes the global '_libc_arm_fpu_present' variable, which
is not used by the current version of our libc/libm.
Fixes#4080
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
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.
This plugin gives access to the Audio_out session by roughly
implementing a OSS pseudo-device. It merely wrapps the session and does
not provide any resampling or re-coding.
Fixes#3891.
In case of contexts blocked in select() the monitor updates the
file-descriptor status, but if the entrypoint is just blocked for the
select handler, the status must be updated explicitly on
dispatch_select().
There is a type mismatch as in the FreeBSD contrib code the type of the
request is 'unsigned long'. So far, only I/O controls where the request
falls into the signed range where used and this was not a problem.
Some of the SNDCTL requests, however, have the bit set.
Fixes#3887.
* add libsparkcrypto source-recipe
* provide ALI files through a new repository by mstein and add the repo
download to the libsparcrypto port-file
* remove dependencies to non-existent contrib ADB files from the library make
files
Fixes: #3852
This patch untangles the interplay of the base library and the libc
during the exit handling.
- The CXA ABI for the atexit handling is now provided by the libc.
For plain Genode components without libc dependency, __cxa_atexit
is a no-op, which is consistent with Genode's notion of components.
- The 'abort' implementation of the base library no longer calls
'genode_exit' but merely 'sleep_forever'. This way, the cxx library
no longer depends on a 'genode_exit' implementation.
- The libc provides 'atexit' support by storing metadata on the
libc kernel's heap now, thereby eliminating the former bounded
maximum number of atexit handlers.
- Shared-library dtors are no longer called via the atexit mechanism
by explicitly by the dynamic linker. This slightly changes the
call order of destructors (adjustment of the ldso test). Functions
marked as destructors are called after the atexit handlers now.
- The libc executes atexit handlers in the application context,
which supports the I/O operations in those handles, in particular
the closing of file descriptors.

* switch to fork of the Ada runtime provided by m-stein
* switch to a Ada-runtime state that provides the Exp_Int package (exponential
function on integers)
* adapt spark lib, symbols, and recipes to incorporate the Exp_Int package
Fixes#3848
* enable all common warnings through default value of CC_ADA_WARN
* treat warnings like errors through default value of CC_ADA_WARN_STRICT
* enable almost all style checks through default value of CC_ADA_WARN_STRICT
* style fixes for aes_cbc_4k
* disable strict warnings and style checks for libsparkcrypto and spark lib
Ref #3848
This commit puts all C++ runtime/support symbols of ld.lib.so in a
dedicated section of base/lib/symbols/ld and mirrors the section to
libports/lib/symbols/libc. So, the libc ABI resolves potential C++
runtime dependencies of base-ABI-agnostic components at link time. The
runtime resolution is done by the linker by symbol lookup in ld.lib.so.
Issue #3720
The function is exposed in libc headers provided by Genode, the code for
the function is being compiled and actually works, but the symbol is
missing from the symbols file resulting in linking failures. Add it to
the libc symbols file.

Generated a separate 'config.h' for arm, arm_64, x86_32, x86_64 for the
current version (6.1.2) of GMP. This became necessary because
configurations differ for each architecture.
