alc 2004-12-12 08:26:50 UTC FreeBSD src repository Modified files: (Branch: RELENG_5) sys/vm vnode_pager.c Log: MFC revision 1.206 Almost nine years ago, when support for 1TB files was introduced in revision 1.55, the address parameter to vnode_pager_addr() was changed from an unsigned 32-bit quantity to a signed 64-bit quantity. However, an out-of-range check on the address was not updated. Consequently, memory-mapped I/O on files greater than 2GB could cause a kernel panic. Since the address is now a signed 64-bit quantity, the problem resolution is simply to remove a cast. Revision Changes Path 1.196.2.2 +1 -1 src/sys/vm/vnode_pager.c
