Hello, thanks for reply.

I build a package version 2.0.34, but problem is reproduced:

Hello Konstantin,

I have tried to reproduce this but without success so far. Whether I install upstream kernel v4.2-rc6 or another kernel version + ib_srp-backport on the initiator system, the result is the same when I block SRP login on the target system: the ib_srp driver keeps trying to log in without creating new SCSI hosts. Are you using a kernel from Greg KH's stable repository or another kernel ? And to which values were the ib_srp kernel module parameters set (cat /etc/modprobe.d/ib_srp.conf) ?

Bart.
