Removes getpwent.c from build because the passwd facilities provided by
the FreeBSD libc will not be used anyway and add stub functions instead.
Now services which need these functions have to implement their own
(e.g. libc_noux).
Apparently, GNU make 3.81 picks the generic '%.h' rule instead of the
more specific 'rpc/%.h' rule during the preparation of the libc.
Changing the order of the rules solves the problem.
libc_resolv is a {free,get}addrinfo() plugin, mainly for use with NOUX.
We prefix the original libc functions to with 'libc_' so there is no
symbol conflict with file_operations.cc.
Most of the libs are needed for DNS related stuff. Since we now
have libc_resolv they are not longer needed. Infact they will
lead to undefined symbols so we remove them alltogther as build
dependency for the libc.
Previously there was not actual timeout handling. If a select() call
set an timeout it would be set to zero instead and was always handled
as blocking i/o. While this works fine for file descriptors which
will be triggerd externally (for example vim through terminal i/o) it
does not work at all for socket descriptors and network operations in
general.
So this commit introduces proper timeout handling and changes the
behaviour of SYSCALL_SELECT so that it now returns more than just
one descriptor at a time.
noux/minimal and noux/net now depend on thread and alarm libraries.
Noux used to trace syscalls by default, which significantly slows down
its execution. This patch disables the tracing by default. It can be
enabled by specifying 'trace_syscalls="yes"' attribute to the Noux
configuration.
This patch resolves a problem with running 'noux_gdb.run'. Right at the
start, GDB would output a message like:
...cli-script.c:1614: internal-error: called with NULL file pointer!
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The LOG output hints at the cause of the problem:
[init -> noux -> /bin/genode-x86-gdb] fcntl: F_GETFL for libc_fd=3
Thanks to cproc for the fix!
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.
