The directory specified by --prefix is not only used to determine
the install location but is also used by -rpath. Therefor it is
better to use $(DESTDIR) to install the binaries to the right
directory and to use --prefix to express the actual location within
NOUX.
This patch adds lighttpd as noux package. However, we do not use the
original build system but rather compile lighttpd directly from the
Genode build system. This is needed because we want to statically link
lighttpd modules into the binary. This mode is (somehow) supported by
the SConscript that comes with lighttpd. However, the GNU build scripts
do not expose this feature.
The port of lighttpd at 'ports/src/app/lighttpd' executes the web server
directly (w/o using Noux). It is accompanied by the lighttpd.run script.
At the current stage, lighttpd is starting up but fails because of an
unsupport fcntl call.
In the current form, only PROT_READ is supported. This case is emulated
by copying the file content into new allocated backing store. Even
though the performance benefits of mmap-using code will not be
preserved, code that relies on mmap can be executed via the libc_noux
or libc_fs plugins, i.e. lightttpd.
Multiple calls to get the dataspace capability on NOVA lead to the situation
that the caller gets each time a new mapping of the same capability at
different indexes.
The client/caller assumes to get every time the very same index, e.g. in
Noux the index is used to look up structures.
Cache the dataspace capability returned via a rm_session for base-nova.
On both 32-bit and 64-bit platforms, 'uint64_t' can be defined as
'unsigned long long', which is the type expected by the %llx
format-string specifier. By unifying the type definitions, we resolve
warnings about unmatching type specifiers. This patch also removes
redundant words from the typedefs.
As of lwip-1.4.x this is not needed anymore because lwip
now always creates a loopback device. This plug-in will
be removed in the future but for now keep it around so
we currently do not need to update the other targets that
depend on it.
Fixes#329.
The bash configure script cannot detect if the 'getcwd()' function in
Genode's libc works correctly, so it assumes that it is broken and makes
bash use its own version of this function. With this patch bash uses the
libc version, which has a Noux-specific implementation in the 'libc_noux'
plugin.
Fixes#324.
The new version works fine but there is an issue with connect()
that needs the included patch:
There is no actual handling of EALREADY in lwip. It sets errno
to EALREADY when the connection was established. Unfortunatly this
is really bad because most programs expect to receive errno EISCONN
if the connection was successfully established. So this behaviour
breaks Qt4 and several noux/net packages (like lynx) because those
programs end up in an endless loop trying to connect via an already
connected socket. The longterm solution would be fixing the wrong
behaviour in lwip (there are already bug-reports on lwip's mailinglist)
but for now, it works well enough to simple change lwip's err_to_errno
table to set errno to EISCONN when the connection was established.
The generic parent_cap.cc overwrote the beginning of the data segment with
to much. Reserved are solely 16 byte, for 64bit we use however 32byte.
Actually, the parent_cap copying is not required at all. The parent cap
selector is at a fixed define place, so that no exported symbols are required
for determination of the parent_cap.
Remove it.
Required to start thread on Genode/NOVA. Without the service it fails with:
int main(): --- init created, waiting for exit condition ---
[init] timer: no route to service "CPU"
[init -> test-moon] Starting ldso ...
[init -> timer] C++ runtime: Genode::Parent::Service_denied

Certain rpc headers are needed for compiling getaddrinfo.c. Unfortunatly
that means we have to generate _a few_ header files which we do when we
prepare the libc.
These header files need to be created before the symlinks. Also, some of
these header files depend on a patch. Therefore we apply the patches
first, generate the header files and in the end we create the symlinks.
Fixes#296.
Since no kernel objects can be created anymore outside Genode::core,
the Vancouver port must be adjusted to use solely the Genode interfaces.
The Vcpu_dispatcher creates all portals via the cpu_session interface and
uses the feature to setup a specific receive window during a IPC (the
cap_session::alloc IPC) to place to be received/to be mapped capability
(virtualization exception portal) at the designed indexes.
The actual vCPU thread extends from a normal Genode::Thread and extends it
by specific vCPU requirements, which are a larger exception base window and
the need by Vancouver to place the SM and EC cap at indexes next to each other.
Fixes#316
Extend Native_capability type to hold a specific selector index where the to
be received cap during a IPC should be mapped to. This feature is required to
place created caps by the cap_session at specific indexes. This feature is
used by Vancouver to setup the virtualization exception portals (created by
the cap_session) at the intended indexes.
Patch prevents following bugs:
* In sleep_forever the thread return from semaphore down if cap is revoked
during destruction of a thread. This causes an endless loop consuming time
not available for other threads.
* In lock_helper and cap_sel_alloc the thread return from the lock() method
even if the semaphore down call failed because of an revoked semaphore.
This lead to the situation that a thread subject to de-construction returns
from the lock method, but not holding the lock, entering the critical section
and modifying state inside the critical section. Another thread in parallel
already in the critical section or entering the critical section also
modifies the state. This lead to curious bugs ...
* thread_nova, thread_start, irq_session
Detect early bugs if the SM is gone unexpectedly where it should never
happen.
