With this patch, the 'not implemented' messages of the pthread function
stubs always get printed to the Genode log console instead of stdout.
Issue #815.
The window scale option (http://tools.ietf.org/html/rfc1323) patch of lwIP
definitely works solely for the receive window, not for the send window.
Setting the send window size to the maximum of an 16bit value, 65535,
or multiple of it (x * 65536 - 1) results in the same performance.
Everything else decrease performance.
We will have to check this window scale patch before using higher values.
Minor speed improvements of ~6Mbit. Additionally a ethernet frame fits now
into one memory allocation per pbuf. Beforehand two were allocated - one being
1514 bytes and another one being 2 bytes (monitored by instrumenting copy loop
in libports/src/lib/lwip/platform/nic.cc).
lwip reports via getsockopt the size of the default size of the receive buffer
to the netperf server. lwip returns 2GB and netperf server uses this value to
allocate some buffers - which of course fails with out of memory.
Reduces the "default size" to some smaller value.
With the commit we are not forced anymore to (but still can) use specific
netperf client options regarding memory allocations of the receive buffer.
The PWD variable contains the current working directory of the original
location where 'make -C' is executed, not the directory specified as
argument of '-C'. The tools referenced by ports/libports, however,
expect PWD to point to the root of the respective repository.
This patch splits the download of signatures from the download of the
archive to improve robustness. This way, signature files will be
downloaded even if the corresponding archive is already in place.
Issue #748
In fact, the sizes were the same the whole time, but by using
the same enum in both cases to instantiate the Packet_stream_tx
and Packet_stream_rx members of the e.g. RPC object, it allows
for more flexible generalization between e.g. source or, sink
objects, when programming event-driven, and implementing generic
handlers for their signals.
This patch makes the handling of failed integrity checks of 3rd-party
packages more robust. Previously, a once failed 'make prepare PKG=curl'
would not leave any trace of the verification state. Hence, a successive
attempt to perform the 'make prepare' step again succeeded even if the
signature check failed.
To solve this problem, the outcome of a successful signature check is
represented by a tag file called 'download/<archive-name>.verified'.
Because the rule for extracting the archive depends on the .verify tag
file, the extraction step is not performed until the signature check
succeeds.
Issue #748
This patch introduces a new platform 'linux_arm' for building and running
Genode/Linux on an ARM device.
Known limitations:
- libc 'setjmp()'/'longjmp()' doesn't currently save/restore floating
point registers
Fixes#746.
In issue #313 the SO_RCVBUF was intended to be enabled, however the current
lwip port looks for another define LWIP_SO_RCVBUF instead of LWIP_RCVBUF.
Fixes#716
lwIP only supports the 'AF_INET' domain, but doesn't check the 'domain'
argument of the 'lwip_socket()' function.
This patch avoids an error message from lwIP when the Arora browser
tries to connect a socket of the 'AF_LOCAL' domain.
Fixes#732.
With this patch, the 'libc_lwip_nic_dhcp' plugin provides the DNS server
address acquired by lwIP via DHCP in the file '/etc/resolv.conf'.
This feature can be disabled from the config file:
<libc resolv="no" />
The static network interface configuration attributes are now also a part
of the '<libc>' config node:
<libc ip_addr="..." netmask="..." gateway="..." />
Fixes#731.
Since checking if the certificate is valid is not that important
(we currently do not check the signature of the archive which is the
bigger issue) we disable the checking to prevent certain wget version
from refusing to download the archive.
Fixes#681
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.
Hereby, the base libraries have been reduced to the following few
libraries:
- startup.mk contains the startup code for normal Genode processes.
On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
processes
Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.
Fixes#18
With the use of the new timer interface, each timer client uses signals.
Hence, programs that have not used signals before will consume slightly
more quota. This is the case for the moon test (triggered on foc_x64_64
only).
This patch introduces keyboard-focus events to the 'Input::Event' class
and changes the name 'Input::Event::keycode' to 'code'. The 'code'
represents the key code for PRESS/RELEASE events, and the focus state
for FOCUS events (0 - unfocused, 1 - focused).
Furthermore, nitpicker has been adapted to deliver FOCUS events to its
clients.
Fixes#609
This patch extends the file-system interface with the ability to monitor
changes of files or directories. The new 'File_system::sigh' function
can be used to install a signal handler for an open node.
The 'ram_fs' server has been enhanced to support the new interface. So
any file or directory changes can now be observed by 'ram_fs' clients.
Fixes#607
Several users of the signal API used custom convenience classes to
invoke signal-handling functions on the reception of incoming signals.
The 'Signal_dispatcher' pattern turned out to be particularly useful. To
avoid the duplication of this code across the code base, this patch
adds the interface to 'base/signal.h'.
Furthermore, the patch changes the 'Signal::num()' return type from int
to unsigned because negative numbers are meaningless here.
Fixes#511
This patch reflects eventual allocation errors in a more specific way to
the caller of 'alloc_aligned', in particular out-of-metadata and
out-of-memory are considered as different conditions.
Related to issue #526.
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.
GCC warns about uninitialized local variables in cases where no
initialization is needed, in particular in the overloads of the
'Capability::call()' function. Prior this patch, we dealt with those
warnings by using an (unreliable) GCC pragma or by disabling the
particular warning altogether (which is a bad idea). This patch removes
the superfluous warnings by telling the compiler that the variable in
question is volatile.
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
Use slab allocators for small object sizes, do it the usual way otherwise.
This patch is related to #363. Using this optimization may be a viable
alternative to switching to the FreeBSD's malloc implementation.
