The constant MFSNAMELEN as defined in: lib/libc/sys/getfsstat.2:#define MFSNAMELEN 16 lib/libc/sys/statfs.2:#define MFSNAMELEN 16 sys/sys/mount.h: #define MFSNAMELEN 16
defines the fs type name and, according to comments, it includes nul terminating character. The following code makes uses of strncpy and involves MFSNAMELEN ./sys/kern/vfs_subr.c:225: strncpy(mp->mnt_stat.f_fstypename, vfsp->vfc_name, MFSNAMELEN); ./sys/kern/vfs_subr.c:2272: strncpy(sbp->f_fstypename, mp->mnt_vfc->vfc_name, MFSNAMELEN); ./sys/kern/vfs_syscalls.c:243: strncpy(mp->mnt_stat.f_fstypename, vfsp->vfc_name, MFSNAMELEN); ./sys/miscfs/procfs/procfs_vfsops.c:190: strncpy(sbp->f_fstypename, mp->mnt_vfc->vfc_name, MFSNAMELEN); ./sys/msdosfs/msdosfs_vfsops.c:669: strncpy(sbp->f_fstypename, mp->mnt_vfc->vfc_name, MFSNAMELEN); ./sys/nfs/nfs_vfsops.c:646: strncpy(&mp->mnt_stat.f_fstypename[0], mp->mnt_vfc->vfc_name, MFSNAMELEN); ./sys/ntfs/ntfs_vfsops.c:628: strncpy(sbp->f_fstypename, mp->mnt_vfc->vfc_name, MFSNAMELEN); ./sys/ufs/ext2fs/ext2fs_vfsops.c:704: strncpy(sbp->f_fstypename, mp->mnt_vfc->vfc_name, MFSNAMELEN); ./sys/ufs/mfs/mfs_vfsops.c:222: strncpy(&sbp->f_fstypename[0], mp->mnt_vfc->vfc_name, MFSNAMELEN); Can be those replace safely by strlcpy without any modification to MFSNAMELEN constant?
