libports: update lwip to STABLE-1.4.1-RC1 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. 2012-08-08 08:55:09 +00:00			`SRC_C += etharp.c`

Merge base libraries into a single library 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 2013-02-14 11:39:51 +00:00			`LIBS = alarm libc timed_semaphore`

libports: adjust lwip's TCP_SND_BUF size 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. 2012-08-27 14:58:51 +00:00			`D_OPTS = ERRNO`
