We will reuse the terminal connection in the stdio filesystem
to implement /dev/tty. Therefor we need to access the terminal
from different locations which is simplified if it is provided
by a singleton.
With this patch the make install target for Noux applications gets defined
in the 'NOUX_INSTALL_TARGET' make variable with 'install-strip' as default.
Fixes#503.
Since the number of the fds in the select call is not necassarily equal
to the number of fds SYSCALL_SELECT returns we have to reset the number
of fds given as argument to select().
This keeps OpenSSH from reading from a non-ready socket.
Fixes#494.
Currently the lookup of a specific record in a tar archive may take a long
time, because the records get searched in sequence. With this patch a tree
structure representing the directory layout gets created when loading the
tar file for speeding up record lookups.
Fixes#491.
The previous implementation disregards the fact that we actually have
to use libc's plugin mechanism if we play with fds. So in the end the
libc did not know to which plugin the fd belonged.
Fixes#493.
Implies support for the ARMv6 architecture through 'base-hw'.
Get rid of 'base/include/drivers' expect of 'base/include/drivers/uart'.
Merge with the support for trustzone on VEA9X4 that came from
Stefan Kalkowski.
Leave board drivers in 'base/include/platform'.
Rework structure of the other drivers that were moved to
'base_hw/src/core' and those that came with the trustzone support.
Beautify further stuff in 'base_hw'.
Test 'nested_init' with 'hw_imx31' (hardware) and 'hw_panda_a2' (hardware),
'demo' and 'signal' with 'hw_pbxa9' (qemu) and 'hw_vea9x4'
(hardware, no trustzone), and 'vmm' with 'hw_vea9x4'
(hardware, with trustzone).
Since FD_ZERO() resets a whole fd_set (which is 128 bytes) using it to
reset dst_fds will override otherwise used memory if the memory was
allocated dynamically and is less than sizeof (fd_set). So instead of
using this macro we reset the fd_set manually.
The Io_receptor is now used to unblock certain I/O channels from lwip's
callback-function.
There was also a bug in which all ready-to-ready fds were overriden by
the ready-to-write ones.
The Socket_io_channel class now uses the Io_channel_backend to provide
the network related methods. In addition the Socket_io_channel_registry
was replaced with a simpler implementation which uses Io_receptors to
unblock I/O channels from the callback-function of lwip.
The eglgears application depends on 'sqrt'. With the old tool chain,
this symbol was resolved through the dependencies of the 'gallium'
library. This does not work anymore for the new tool chain.
A similar issue arised for avplay, where we need to explicitly
state the av components in the LIBS declaration of the target.
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
This patch moves the thread iterator function declarations in GDB
monitor's 'Cpu_session_component' above the 'CPU session interface'
comment, because these functions are not part of the CPU session
interface anymore.
Fixes#10.
If during the file system iterations in the 'stat()', 'rename()' or
'mkdir()' funtions of the 'Dir_file_system' class any file system
returns an error code other than 'ERR_NO_ENTRY', return immediately.
Fixes#376.
With this patch, when a child exits, all of its open file descriptors get
closed immediately. This is necessary to unblock the parent if it is
trying to read from a pipe (connected to the child) before calling
'wait4()'.
Fixes#357.
Don't map all memory of the VM at once, instead only the one permitted
by the memory model. Otherwise memory regions get mapped which must not,
where each instruction and memory access have to cause an exception in
order to emulate it step by step.
Classes in Vancouver expect to get zero initialised memory when using memory
from the heap. Some classes don't initialize member variables as they should
do.
Reserve memory region for VM as early as possible before any other
memory allocation happens. Otherwise it could happen that heap
allocations will use part of the virtual region we require for the VM.
