- 'kill()' syscall added
- 'wait()' gets unblocked when a signal occurs
- syscalls can get called from a signal handler without corrupting the 'sysio' object
- the child's exit status gets correctly reported to 'wait()'
- SIGCHLD gets ignored by default
- pending signals survive 'execve()'
Fixes#1035.
File systems using the File_system_session interface can now be
synchronized by using this syscall. This is needed for file system
that maintain an internal cache, which should be flushed.
Fixes#1008.
There are certain programs that need gettimeofday(), e.g.
network-related tools like ping(1) etc. but also filesystem-related
programs like find(1) etc. and of course time-related programs like
date(1).
As there is currently no interface in Genode for actually using clock
devices like RTC on x86 (though there is a driver for it) we "abuse"
the timeout_scheduler thread to at least provide flow-of-time.
Noux: add clock_gettime() implementation
For now, only CLOCK_SECOND is supported.
Noux: add utimes() dummy
Fixes#401
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.
Noux/net adds network functionality to noux. Currently most basic
network related system calls including 'accept', 'bind', 'connect',
'listen', 'recv', 'send', 'shutdown', and 'socket' are implemented by
wrapping lwip's network functions.
At the moment noux/net is rarely usable, though it is possible to
use netcat to send a message to a netcat server which listen on a
given port in noux/net.
This patch introduces support for stacked file systems alongside new
glue for accessing file-system implementations provided via Genode's
new file-system-session interface.
Using stacked file systems, an arbitrary number of file systems (such
as tar archives or file systems implemented as separate Genode
components) can be composed to form one merged virtual file system.
An example is given via the 'ports/run/noux_bash.run' script. This run
script creates a virtual file system out of multiple tar archives each
containing the content of a particular GNU package. In addition, one
'ram_fs' is mounted, which enables Noux to perform write operations.
This way, the shell output can be redirected to a file, or files can
be saved in VIM.
Fixes#103.
