From: Vasu Dev <[email protected]> Currently fc_host mfs is not getting updated in case its changed during FLOGI and that leaves fc_host to show its initial old value in sysfs, so instead have fc_host mfs updated along with updating lport mfs during FLOGI.
Also in case of bad mfs during flogi, error out instead of continuing with flogi. [Bhanu: Updated this patch to modify the error condition to error out only when mfs is not in the supported range.] [ Robert Love: Updated this patch to apply to linus' kernel. ] Signed-off-by: Vasu Dev <[email protected]> Tested-by: Ross Brattain <[email protected]> Signed-off-by: Bhanu Prakash Gollapudi <[email protected]> Signed-off-by: Robert Love <[email protected]> --- drivers/scsi/libfc/fc_lport.c | 12 +++++++----- 1 files changed, 7 insertions(+), 5 deletions(-) diff --git a/drivers/scsi/libfc/fc_lport.c b/drivers/scsi/libfc/fc_lport.c index ef9560d..cc83b66 100644 --- a/drivers/scsi/libfc/fc_lport.c +++ b/drivers/scsi/libfc/fc_lport.c @@ -1742,17 +1742,19 @@ void fc_lport_flogi_resp(struct fc_seq *sp, struct fc_frame *fp, mfs = ntohs(flp->fl_csp.sp_bb_data) & FC_SP_BB_DATA_MASK; - if (mfs >= FC_SP_MIN_MAX_PAYLOAD && - mfs <= lport->mfs) { - lport->mfs = mfs; - fc_host_maxframe_size(lport->host) = mfs; - } else { + + if (mfs < FC_SP_MIN_MAX_PAYLOAD || mfs > FC_SP_MAX_MAX_PAYLOAD) { FC_LPORT_DBG(lport, "FLOGI bad mfs:%hu response, " "lport->mfs:%hu\n", mfs, lport->mfs); fc_lport_error(lport, fp); goto err; } + if (mfs <= lport->mfs) { + lport->mfs = mfs; + fc_host_maxframe_size(lport->host) = mfs; + } + csp_flags = ntohs(flp->fl_csp.sp_features); r_a_tov = ntohl(flp->fl_csp.sp_r_a_tov); e_d_tov = ntohl(flp->fl_csp.sp_e_d_tov); _______________________________________________ devel mailing list [email protected] https://lists.open-fcoe.org/mailman/listinfo/devel
