Category Tags: defect_repair general_release critical Path Name: /hp-ux_patches/s700_800/11.X/PHKL_24005 Symptoms: PHKL_24005: ( SR: 8606157079 CR:JAGad26413) System returns Bad address (EFAULT) even when the application supplied a valid address. Defect Description: PHKL_24005: ( SR: 8606157079 CR:JAGad26413) The system checks the access rights for the page twice before copying a page in memory. The second check is done if the page was not already in memory and was brought in by a fault. This second check can fail under a race condition. Resolution: The solution is not to check the access rights again if the fault is resolved - resolving the fault ensures that the page is in memory with proper access rights.
