Current fc_eh_host_reset leaves lport offline permanently due to FLOGI response getting handled by LOGO response from last reset as both had same exchange id. So fix this by having end to end exches clean-up using exchange abort along exches reset done from fc_eh_host_reset. This would avoid exchanges collision between the sessions across the reset. In this case implicit login should have done that but no aborting support for FIP frames, so just wait till lport->r_a_tov before restarting next flogi to ensure all exchanges are good to use again for next session. Below is the trace of LOGO from older session coming ahead of FLOGI response with same exche id 0x203:- 617 86.435165 4e.00.0b -> ff.ff.fc FC ELS LOGO 0x203 618 86.435195 4e.00.0b -> b6.02.00 FC ELS LOGO 0x213 619 86.435220 4e.00.0b -> 18.03.00 FC ELS LOGO 0x223 620 86.435244 4e.00.0b -> 18.02.00 FC ELS LOGO 0x233 621 86.435267 4e.00.0b -> 18.01.00 FC ELS LOGO 0x243 622 86.435349 00.00.00 -> ff.ff.fe FC ELS FLOGI 0x203 623 86.435549 ff.ff.fc -> 4e.00.0b FC ELS ACC (LOGO) 0x203 624 86.438721 ff.ff.fe -> 4e.00.0b FC ELS ACC (FLOGI) 0x203 625 86.442059 18.03.00 -> 4e.00.0b FC ELS ACC (LOGO) 0x223 626 86.443683 b6.02.00 -> 4e.00.0b FC ELS ACC (LOGO) 0x213 627 86.447693 18.01.00 -> 4e.00.0b FC ELS ACC (LOGO) 0x243 628 86.453499 18.02.00 -> 4e.00.0b FC ELS ACC (LOGO) 0x233 Signed-off-by: Vasu Dev <vasu.dev@intel.com> Tested-by: Ross Brattain <ross.b.brattain@intel.com> Reviewed-by: Yi Zou <yi.zou@intel.com> Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com> |
