There are certain programms which check if an fd is open by calling
fcntl(fd, F_GETFL, ...). So to keep them happy we return true if
such an request was done to our terminal fd's.
Explanation why --disable-rpath-hack is needed:
When building on pistachio_x86 $(LDFLAGS) contains '-L[...]/l4/lib'
which will be transformed by autoconf to '-rpath [...]/l4/lib'.
Now the problem at hand is that we pretend to be FreeBSD when we are
actually not. So autoconf assumes it is valid to use '-path' when it
is actually not.
Also we use zlib for (de)compressing gzipped streams/files instead of
calling gzip as this currently somewhat buggy.
These device are mandatory for most programs (well, at least null
is required to be present for a POSIX compliant OS, which Noux is
actually not). But for proper shell-script support we will need
them anyway.
There are certain programs which need the information that is stored in
'struct passwd'. This commit introduces configurable user information
support to NOUX.
One can set the user information via <user> in NOUX config:
! <config>
! <user name="baron" uid="1" gid="1">
! <shell name="/bin/bash" />
! <home name="/home" />
! </user>
! [...]
! </config>
When <user> is not specified default values are used. Currently these
are 'root', 0, 0, '/bin/bash', '/'.
Note: this is just a single user implementation because each Noux instance
has only one user or rather one identity and there will be no complete
multi-user support in Noux. If you need different users, just start new
Noux instances for each of them.
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.
