Subject: [PATCH v2 06/11] serve: advertise trace2 SID in v2 capabilities
Date: Mon,  2 Nov 2020 14:31:04 -0800	[thread overview]
Message-ID: <9573428cc02111d3141ec2481bf679b31a5139e2.1604355792.git.steadmon@google.com> (raw)
In-Reply-To: <cover.1604355792.git.steadmon@google.com>

When trace2 is enabled and trace2.advertiseSID is true, advertise the
server's trace2 session ID for all protocol v2 connections via the new
trace2-sid capability.
