>From 5675bcbce8054eceb6ac69d46224895866365a75 Mon Sep 17 00:00:00 2001 From: Joshua Branson Date: Sat, 27 Oct 2018 09:17:53 -0400 Subject: [PATCH] * I modified tcp_ip_stack to reflect that lwip should replace pfinet. To: bug-hurd@gnu.org * I modified open_issues/device_drivers_and_io_systems to include rump kernel. * I created a rump kernel wiki page, and I linked to it from the project_ideas/tcp_ip_stack webpage. * I added an obsolete logo to the DDE page, to pointe people to the Rump kernel page. --- .../gsoc/project_ideas/driver_glue_code.mdwn | 2 +- .../gsoc/project_ideas/tcp_ip_stack.mdwn | 3 +- dde.mdwn | 9 +++++ .../device_drivers_and_io_systems.mdwn | 2 + rump_kernel.mdwn | 40 +++++++++++++++++++ 5 files changed, 54 insertions(+), 2 deletions(-) create mode 100644 rump_kernel.mdwn diff --git a/community/gsoc/project_ideas/driver_glue_code.mdwn b/community/gsoc/project_ideas/driver_glue_code.mdwn index 1771756e..db1816c9 100644 --- a/community/gsoc/project_ideas/driver_glue_code.mdwn +++ b/community/gsoc/project_ideas/driver_glue_code.mdwn @@ -27,7 +27,7 @@ This is [[!GNU_Savannah_task 5488]].
