ead82533278502428883085a787d5a00f15e5eb9 Author: Jeongjun Park Date: Mon Aug 19 13:05:46 2024 +0900 jfs: fix out-of-bounds in dbNextAG() and diAlloc() [ Upstream commit e63866a475562810500ea7f784099bfe341e761a ] In dbNextAG() , there is no check for the case where bmp->db_numag is greater or same than MAXAG due to a polluted image, which causes an out-of-bounds. Therefore, a bounds check should be added in dbMount(). And in dbNextAG(), a check for the case where agpref is greater than bmp->db_numag should be added, so an out-of-bounds exception should be prevented. Additionally, a check for the case where agno is greater or same than MAXAG should be added in diAlloc() to prevent out-of-bounds.
