has been resolved:\n\next4: inline: fix len overflow in ext4_prepare_inline_data\n\nWhen running the following code on an ext4 filesystem with inline_data\nfeature enabled, it will lead to the bug below.\n\n fd = open(\"file1\", O_RDWR | O_CREAT | O_TRUNC, 0666);\n ftruncate(fd, 30);\n pwrite(fd, \"a\", 1, (1UL << 40) + 5UL);\n\nThat happens because write_begin will succeed as when\next4_generic_write_inline_data calls ext4_prepare_inline_data, pos + len\nwill be truncated, leading to ext4_prepare_inline_data parameter to be 6\ninstead of 0x10000000006.\n\nThen, later when write_end is called, we hit:\n\n BUG_ON(pos + len > EXT4_I(inode)->i_inline_size);\n\nat ext4_write_inline_data.\n\nFix it by using a loff_t type for the len parameter in\next4_prepare_inline_data instead of an unsigned int.\n\n[ 44.545164] ------------[ cut here ]------------\n[ 44.545530] kernel BUG at fs/ext4/inline.c:240!\n[ 44.545834] Oops: invalid opcode: 0000 [#1] SMP NOPTI\n[ 44.546172]
