E.g., the script manually tried to configure lighttpd and used the old
porting directory structure that was integrated in the repos. For the
same reason it produced compile errors with noux packages.
Ref #2398
We do not have debug symbols in the bin/ binaries anymore. Thus, use the
debug/ binaries instead. We now have kernel specific binary names for
ld.lib.so and some others. Adapt, to this fact as well. For doing so
without unnecessary output, provide a new parameter "silent" at the
"kernel_specific_binary" procedure.
Ref #2398
A dataspace capability request to a ROM service may invalidate any
previously issued dataspace. Therefor no requests should be made while a
session dataspace is mapped. Reducing calls to the session also improves
performance where servicing a ROM request has a significant cost.
Fix#2418
There are programs, e.g. curl, that check if a connection was
established successfully by looking at SO_ERROR. Pretend that
the getsockopt() call was executed to keep them happy. If they
try to use a broken connection, the other socket functions will
bail.
This patch changes the noux build rules to produce a tar archive in
'bin/', alleviating the need for this step from the run scripts.
This way, the visible result of a built noux package is a single (tar)
file in '<build-dir>bin/', which is suited for the use as a ROM module.
The 'Stack_area_ram_session' is now a 'Stack_area_ram_allocator', which
simplifies the code and remove a dependency from the 'Ram_session'
interface, which we want to remove after all.
Issue #2407
By supplying a statically allocated initial block to the slab allocator
for signal contexts, we become able to construct a 'Signal_broker' (the
back end for the PD's signalling API) without any dynamic memory
allocation. This is a precondition for using the PD as meta-data
allocator for its contained signal broker (meta data allocations must
not happen before the PD construction is complete).
Issue #2407
If a child is allowed to constrain physical memory allocations but left
the 'phys_start' and 'phys_size' session arguments blank, init applies
builtin constraints for allocating DMA buffers.
The only component that makes use of the physical-memory constraint
feature is the platform driver. Since the built-in heuristics are
applied to the platform driver's environment RAM session, all
allocations performed by the platform driver satisfy the DMA
constraints.
To justify building-in these heuristics into init as opposed to
supplying the values as configuration arguments, the values differ
between 32 and 64 bit. The configuration approach would raise the need
to differentiate init configurations for both cases, which are
completely identical otherwise.
Issue #2407
This commit removes support for limitation of RAM allocations from the
platform_drv. A subsequent commit adds this feature to init.

Issue #2407
By separating the session-interface concerns from the mechanics of the
dataspace creation, the code becomes simpler to follow, and the RAM
session can be more easily merged with the PD session in a subsequent
step.
Issue #2407
This patch allows core's 'Signal_transmitter' implementation to sidestep
the 'Env::Pd' interface and thereby adhere to a stricter layering within
core. The 'Signal_transmitter' now uses - on kernels that depend on it -
a dedicated (and fairly freestanding) RPC proxy mechanism for signal
deliver, instead of channeling signals through the 'Pd_session::submit'
RPC function.
With the capability-quota mechanism, the terminal-session won't always
be constructed completely on the first try (we may run out of caps in
the middle of the construction). Therefore, all members of the object
must be properly destructable. Furthermore, the patch replaces the
sliced heap by a heap to avoid allocating a new dataspace for each line
of the cell array.
