From: Sage Weil Date: Mon, 15 Mar 2010 22:47:22 +0000 (-0700) Subject: ceph: fix authenticator timeout X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=63733a0fc55cca74b1911769633dc5dfd1a45907;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ceph: fix authenticator timeout We were failing to reconnect to services due to an old authenticator, even though we had the new ticket, because we weren't properly retrying the connect handshake, because we were calling an old/incorrect helper that left in_base_pos incorrect. The result was a failure to reconnect to the OSD or MDS (with an authentication error) if the MDS restarted after the service had been up a few hours (long enough for the original authenticator to be invalid). This was only a problem if the AUTH_X authentication was enabled. Now that the 'negotiate' and 'connect' stages are fully separated, we should use the prepare_read_connect() helper instead, and remove the obsolete one.
