Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.
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.
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.
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.
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
This patch adds libstdc++ to libports. With the previous version of the
stdcxx library, the build system used the C++ standard library that
comes with the compiler. This mechanism was prone to inconsistencies of
types defined in the header files used at compile time of the tool chain
and the types provided by our libc. By building the C++ standard library
as part of the Genode build process, such inconsistencies cannot happen
anymore.
Note that the patch changes the meaning of the 'stdcxx' library for
users that happened to rely on 'stdcxx' for hybrid Linux/Genode
applications. For such uses, the original mechanism is still available,
in the renamed form of 'toolchain_stdcxx'.
The old values were much too small and the current ones are probably to
large but the TCP send throuhgput has increased noticeable (a few MiB/s
on the Pandaboard).
Fixes#343.
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).
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.
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.
The new version works fine but there is an issue with connect()
that needs the included patch:
There is no actual handling of EALREADY in lwip. It sets errno
to EALREADY when the connection was established. Unfortunatly this
is really bad because most programs expect to receive errno EISCONN
if the connection was successfully established. So this behaviour
breaks Qt4 and several noux/net packages (like lynx) because those
programs end up in an endless loop trying to connect via an already
connected socket. The longterm solution would be fixing the wrong
behaviour in lwip (there are already bug-reports on lwip's mailinglist)
but for now, it works well enough to simple change lwip's err_to_errno
table to set errno to EISCONN when the connection was established.
libcrypto provides certain optimized assembler functions which
unfortunatly are non-pic. Therefore this asm code is removed
and libcrypto is build with -DOPENSSL_NO_ASM.
Because the asm code is not needed anymore, its generation is
also removed from openssl.mk.
import-libssl.mk was also added because it is essential for building
programs which depend on libssl.
Fixes#291.
Fixes#294.
This patch implements the 'readv()' function in the libc.
A lock guard prevents the parallel execution of either or both of the
'readv()' and 'writev()' functions.
Fixes#279.
This patch implements the 'pread()' and 'pwrite()' functions in the libc.
A lock guard prevents the parallel execution of either or both functions.
Fixes#278.
