Created attachment 43871 [details] [review] build: make it silent This patch make it easier to spot warnings in compilation. It should work with older versions of automake that don't support silent rules. If you want verbose build, make V=1.

So that's why there was a if(channel) condition. Now, it goes through sync_write anyway, either channel->num_{,common}_caps == 0 (without the AUTH_SELECTION cap, or with it, then channel->num_common_caps == 1) So it looks fine to me. Agree? ACK to all. (don't forget the SPICE_UNUSED and the fix to the sync_write - please post the updated patches here for future reference). committed to master (ghhh, I forgot to reorder: build add --with-sasl) commit 8f9cbd19dbf3612abeafae60bdc4df2a97552b91 Author: Marc-André Lureau <marcandre.lureau@redhat.com> Date: Fri Feb 11 04:04:28 2011 +0100 server: add SASL support We introduce 2 public functions to integrate with the library user. spice_server_set_sasl() - turn on SASL spice_server_set_sasl_appname() - specify the name of the app (It is used for where to find the default configuration file) The patch for QEMU is on its way. https://bugs.freedesktop.org/show_bug.cgi?id=34795 commit f4dddc50f06f90d7ff97d4ed60c6197c85814c5e Author: Marc-André Lureau <marcandre.lureau@redhat.com> Date: Tue Feb 22 13:54:09 2011 +0100 server: add auth mechanism selection https://bugs.freedesktop.org/show_bug.cgi?id=34795 commit 4f983b2c9c642ac96abf214cefc1c51fad90791e Author: Marc-André Lureau <marcandre.lureau@redhat.com> Date: Tue Feb 22 03:52:38 2011 +0100 server: add reds_channel_dispose() Try to have a common base dispose() method for channels.

This patch set implements SASL channel authentication as described in the protocol patch entitled "protocol: add common channel caps for AUTH mechanism selection". SASL is enabled via spice_server_set_sasl(), that a following QEMU patch implements. For testing, current spice-gtk git implements the client side. Changed since v1: - removed the RFC SSL, since it's not doing anything useful - splitted the patch moving to stream_{read,write}() functions - fixed the if {} else {} style - renamed s/RedsSASLContext/RedsSASL
