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.
After this commit "make prepare" uses HTTP, HTTPS, or FTP where possible
fvor downloading third-party source codes. This prevents problems with
strict firewall rules where only selected ports are usable.
Unfortunately, git.l4android.org does not support Git via HTTP and,
therefore, the sources need a working Git port (9418).
Fixes#443.
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.
Make sure unlock is called when 'global_mutex' reaches zero count. Add verbose
variable in order to disable some output. Disable irritating 'Overflow' messages
in 'sys_mbox_post' and 'sys_mbox_try_post' per default. This may happen and is
not an error, since the ring buffer is full and will be emptied eventually.
Remove priority from genode_org run script.
Should fix#347
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.
Use 'Nic::Packet_allocator', wait for acknowledgements if packet allocation
fails. Updated 'lwip.run' and 'genode_org.run' to support OMAP4 correctly. Use
memcpy to copy PBUFs
May resolve issue #347
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.
The memory allocation heuristics in the usb driver provided by dde_linux
changed with the recent commit 71b2b42936.
Apparently, the new variant requires a larger memory pool. Increasing
the quota is a temporary fix until the memory allocator gets revisited.
The 'find' program can abort if the 'gettimeofday()' function returns -1,
which it currently does. With this patch the 'gettimeofday()' returns a
dummy time instead to prevent such a termination.
Fixes#353.
With this patch the 'Vfs_io_channel::lseek()' function takes the offset
argument into account when calculating the new seek offset in the SEEK_CUR
and SEEK_END cases.
Fixes#352.
This patch introduces the functions 'affinity' and 'num_cpus' to the CPU
session interface. The interface extension will allow the assignment of
individual threads to CPUs. At this point, it is just a stub with no
actual platform support.
With this patch environment variables always get stored as zero-separated
strings in buffers of type 'Sysio::Env'. This fixes the problem that
environment variables with non-alphanumeric characters did not get set
correctly in child processes.
Fixes#340.
Change the uid/gid entries in the stat syscall to have the same values
on all filesystems that are used in the current noux-instance according
to the specified values in noux' config.
Fixes#338.
Programs use the errno value to check which error exactly occured.
It is mandatory for non-blocking I/O, e.g. connect() gets the current
state of the connection by looking at the returned errno values.
Fixes#337.
