* Document EINTEGRITY errors for many system calls.John Baldwin2020-03-301-1/+8
| | | | | | | | | | | | | | | | | | | EINTEGRITY was previously documented as a UFS-specific error for mount(2). This documents EINTEGRITY as a filesystem-independent error that may be reported by the backing store of a filesystem. While here, document EIO as a filesystem-independent error for both mount(2) and posix_fadvise(2). EIO was previously only documented for UFS for mount(2).

* When mounting a UFS filesystem, return EINTEGRITY rather than EIOKirk McKusick2020-03-111-0/+4
| | | | | | | | | | | | when a superblock check-hash error is detected. This change clarifies a mount that failed due to media hardware failures (EIO) from a mount that failed due to media errors (EINTEGRITY) that can be corrected by running fsck(8).

* Add two options to allow mount to avoid covering up existing mount points.Sean Eric Fagan2019-09-231-1/+15
| | | | | | | | | | | | | | | | | | | The two options are * nocover/cover: Prevent/allow mounting over an existing root mountpoint. E.g., "mount -t ufs -o nocover /dev/sd1a /usr/local" will fail if /usr/local is already a mountpoint. * emptydir/noemptydir: Prevent/allow mounting on a non-empty directory. E.g., "mount -t ufs -o emptydir /dev/sd1a /usr" will fail. Neither of these options is intended to be a default, for historical and compatibility reasons.

| | | | | | | | | | | | | | | | | specified directory is not found in the mount list. Before the MNT_BYFSID changes, unmount(2) used to return ENOENT for a nonexistent path and EINVAL for a non-mountpoint, but we can no longer distinguish between these cases. Of the two error codes, EINVAL was more likely to occur in practice, and it was the only one of the two that was documented. Update the manual page to match the current behaviour.

| | | | | | | | | | | | | | | | | | | | | system by specifying the file system ID instead of a path. Use this by default in umount(8). This avoids the need to perform any vnode operations to look up the mount point, so it makes it possible to unmount a file system whose root vnode cannot be looked up (e.g. due to a dead NFS server, or a file system that has become detached from the hierarchy because an underlying file system was unmounted). It also provides an unambiguous way to specify which file system is to be unmunted. Since the ability to unmount using a path name is retained only for compatibility, that case now just uses a simple string comparison of the supplied path against f_mntonname of each mounted file system.

* Separate the description of the flags for mount(2) and unmount(2)Ian Dowse2003-06-301-14/+16
| | | | | | | | | | | to clarify which system call accepts which arguments. Previously the manual page gave the impression that calling unmount() with flags of (MNT_FORCE | MNT_UPDATE | MNT_RDONLY) would downgrade a read-write mount to read-only, which is clearly untrue; to do that, these flags should be passed to mount() instead.

| | | | | | | | | | | | | | | | | | | Ever since I first say the way the mount flags were used I've hated the fact that modes, and events, internal and exported, and short-term and long term flags are all thrown together. Finally it's annoyed me enough.. This patch to the entire FreeBSD tree adds a second mount flag word to the mount struct. it is not exported to userspace. I have moved some of the non exported flags over to this word. this means that we now have 8 free bits in the mount flags. There are another two that might well move over, but which I'm not sure about. The only user visible change would have been in pstat -v, except that davidg has disabled it anyhow. I'd still like to move the state flags and the 'command' flags apart from each other.. e.g. MNT_FORCE really doesn't have the same semantics as MNT_RDONLY, but that's left for another day.
