Replacing the node lookup table with an Id_space removes the
limit on open handles per session and allows mutal associativity
between File_system handles and local VFS handles.
Fix#2221
The test now forks twice - the parent forks a child and the child itself
forks a grand child. Both, parent and child, wait for termination of
their forked process with waitpid(). Additionally, the run script now
checks for exit of the parent (not any noux process).
First, calls to manage and dissolve signal contexts now check if the
signal receiver was constructed. There is a small window during suspend
where it is destructed before reconstructed again.
Last, we ensure that processing of incoming signal was deblocked by the
suspend signal before entering the suspend operation. This way we ensure
already queued signal are handled.
The block file system wrongly modified the seek offset during a
read-modify-write operation that is required for sub-block-size
requests. This led to problems whenever such write requests spanned
multiple blocks and thereby were handled in multiple iterations.
Fixes#2262
This test reproduces an issue of the VFS block file system when the
underlying block device has a coarser granularity than the block
requests issued by the VFS client. I.e., if the underlying block device
has a block size of 4K, writing a sequence of (non-4K-aligned) 512 blocks
that crosss a 4K boundary corrupts the data on the block device.
Issue #2262
The new utility at 'os/static_parent_services.h' allows the creation of
a registry of parent services at compile time and thereby eliminates the need
for dynamic memory allocations whenever the set of services is known at
compile time as is the case for most uses of 'Slave::Policy'. The commit
showcases the utility in the bomb test.
This commit enables compile-time warnings displayed whenever a deprecated
API header is included, and adjusts the existing #include directives
accordingly.
Issue #1987
On Odroid XU the SD card driver comes up and finds a card but for card
access it seems that we would need a platform driver like on Arndale.
On imx_53, the first SDHCI MMIO access faults. This is likely due to the
AIPSTZ memory bridge. On HW, we initialize the AIPSTZ in the kernel, but
when I tried doing that in the platform driver instead, the first AIPSTZ
MMIO access faults ^^ So I gave up for now and removed support.
Fixes#2259
Parse ``<env key="..." value=".."/>`` nodes from the config ROM and
populate a list at the 'genode_envp' and 'environ' symbols.
Test script at run/libc_getenv.
Fix#2236
In combination with run/image/uboot, run/boot_dir/foc expected a file link it
created itself to be a directory by trying to create another file link inside
it.
Ref #1987
For all tests
* use Component::construct instead of main
* use new connection constructors with env argument
* use log instead of printf
For some tests
* replace signal receivers with signal handlers
* replace global static variables with Main class members
* remove unnecessary multithreading
* model test steps as classes that are independent from each other and managed
by Main as constructibles
* use references instead of pointers and exceptions instead of error codes
* use Attached_* helpers intead of doing attach/detach manually
* use helpers like String, Id_space, Registry instead of arrays and lists
* make the run script suitable for automated execution and conclusion

In the past, the Genode::destroy, that is called by the RAM-FS-chunk destructors,
issued Allocator::free instead of the C++ delete. Therefore it was possible to
use the size argument of Allocator::free for the allocation tracker in the
RAM-FS-chunk test. Nowadays, we have to keep track of the allocation sizes
ourselves because delete doesn't hand over the size.

The FB Block Adapter in os/src/test visualizes a block session via a
Framebuffer session. As far as I can see, it is not a test but rather
the base for a bump-in-the-wire component. However, for this role it
currently lacks a Block back-end. As it also would have to be updated to
use the new base API I removed it instead, leaving only its git
history as inspiration if someone needs such a component in the future.

Ref #1987
lesskey and lessecho missed the declaration of ${LIBS} on the compiler
command line, which ended up in unusable programs.
> file noux-pkg/less/lesskey.broken
noux-pkg/less/lesskey.broken: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter *empty*, not stripped
> file noux-pkg/less/lesskey
noux-pkg/less/lesskey: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter ld.lib.so, not stripped
The issue was identified because -O0 builds broke with
ld: lesskey: The first section in the PT_DYNAMIC segment is not the .dynamic section
Unfortunately, this simple fix renders both tools also dependent to libm
and ncurses which they don't use.
This streamlines the Genode-specific interface for both 32-bit and
64-bit architectures and fixes dynamic-linking issue with the rump
VFS due to differing size_t types.
This function returns the information whether the used platform relies
on USB HID for interactive scenarios by default as is the case for most
ARM platforms. In contrast, for x86 the USB driver can be omitted because
we can use the PS/2 driver (that is readily available in repos/os/).
If the detach address is not the beginning of the region, one gets:
"virtual void Genode::Allocator_avl_base::free(void*): given
address (0x180e0) is not the block start address (0x18000)"
Instead, print an explicit warning in front of the detach call.
Cleaning up LWIP when returning from the main function sporadically
leads to endless errors "Error: sys_arch_mbox_fetch: unknown exception
occured!". We let the client sleep forever at the end of its main function
to prevent tests from failing due to a flooded log.
Reg #2193
* get rid of printf
* use exceptions instead of error codes
* use Id_space instead of the individual block device registry
* use Cstring instead of char const*
* move method definitions > 1 line to .cc files
* rename Block Block_driver and Serial Serial_driver to avoid name clashes
with the Genode namespace and thereby simplify the code
* use lambdas for Block device lookup and apply
* switch to the Component framework
* don't use env(), config(), ... and hand over env to each connection
* use Attached_mmio and Attached_rom/ram_dataspace instead of manual
solutions
Fixes#2223
The init component used to create the CPU/RAM/PD/ROM sessions (the child
environment) for its children by issuing session requests to its parent,
which is typically core. This policy was hard-wired. This patch enables
the routing of the environment sessions of the children of init
according to the configured routing policy.
Because there is no hard-wired policy regarding the environment sessions
anymore, routes to respective services must be explicitly declared in
the init configuration. For this reason, the patch adjusts several run
scripts in this respect.
This patch removes the outdated '<if-args>' special handling of session
labels. The '<if-args>' feature will eventually be removed completely
