Neels Hofmeyr gerrit-no-reply at lists.osmocom.orgHello Harald Welte, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/10636 to look at the new patch set (#2). Change subject: lchan_fsm: lchan_fail_to(): store target state early ...................................................................... lchan_fsm: lchan_fail_to(): store target state early lchan_fail_to() is a macro to preserve useful source file:line information in logging. But a side effect is that its target state argument might evaluate differently at the end of the macro, if, say, the fi->state has changed. I hit such an instance on timeout of WAIT_RLL_RTP_ESTABLISH: lchan_fsm_timer_cb() calls macro lchan_fail(), which calls lchan_fail_to(lchan_fsm_on_error[fi->state]). Unlike for normal function invocation, this argument changes as fi->state changes. Since releasing the lchan_rtp_fsm already transitions the lchan fi into WAIT_RF_RELEASE_ACK, the final state change of lchan_fail_to() suddenly evaluates to the broken state instead of the intended WAIT_RF_RELEASE_ACK. Early in lchan_fail_to(), store the argument's value as of macro invocation.
