From 038bc6e775462e762adbfbba9979ad1604a59e1c Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 5 Dec 2012 17:56:19 +0100 Subject: [PATCH] score: Critical fix for timer server Under certain conditions it is possible that a call to _Watchdog_Adjust_to_chain() happens with a unit parameter value of zero (for example sptests/spintrcritical17). Remove superfluous checks that prevent an adjust to a chain of a watchdog chain which first element has a delta zero value. --- cpukit/score/src/watchdogadjusttochain.c | 7 ------- 1 file changed, 7 deletions(-) diff --git a/cpukit/score/src/watchdogadjusttochain.c b/cpukit/score/src/watchdogadjusttochain.c index 3b8684a978..902d9de380 100644 --- a/cpukit/score/src/watchdogadjusttochain.c +++ b/cpukit/score/src/watchdogadjusttochain.c @@ -33,16 +33,9 @@ void _Watchdog_Adjust_to_chain( ISR_Level level; Watchdog_Control *first; - if ( units <= 0 ) { - return; - } - _ISR_Disable( level ); while ( 1 ) { - if ( units <= 0 ) { - break; - } if ( _Chain_Is_empty( header ) ) { break; }
