<para>
The dma-buf subsystem provides the framework for sharing buffers
for hardware (DMA) access across multiple device drivers and
subsystems, and for synchronizing asynchronous hardware access.
</para>
<para>
This is used, for example, by drm "prime" multi-GPU support, but
is of course not limited to GPU use cases.
</para>
<para>
The three main components of this are: (1) dma-buf, representing
a sg_table and exposed to userspace as a file descriptor to allow
passing between devices, (2) fence, which provides a mechanism
to signal when one device as finished access, and (3) reservation,
which manages the shared or exclusive fence(s) associated with
the buffer.

Each mount of the devpts filesystem is now distinct such that ptys
and their indicies allocated in one mount are independent from ptys
and their indicies in all other mounts.
To support containers, we now allow multiple instances of devpts filesystem,
such that indices of ptys allocated in one instance are independent of indices
allocated in other instances of devpts.
All mounts of the devpts filesystem now create a /dev/pts/ptmx node
with permissions 0000.
To preserve backward compatibility, this support for multiple instances is
enabled only if:
To retain backwards compatibility the a ptmx device node (aka any node
created with "mknod name c 5 2") when opened will look for an instance
of devpts under the name "pts" in the same directory as the ptmx device
node.
- CONFIG_DEVPTS_MULTIPLE_INSTANCES=y, and
- '-o newinstance' mount option is specified while mounting devpts
IOW, devpts now supports both single-instance and multi-instance semantics.
If CONFIG_DEVPTS_MULTIPLE_INSTANCES=n, there is no change in behavior and
this referred to as the "legacy" mode. In this mode, the new mount options
(-o newinstance and -o ptmxmode) will be ignored with a 'bogus option' message
on console.
If CONFIG_DEVPTS_MULTIPLE_INSTANCES=y and devpts is mounted without the
'newinstance' option (as in current start-up scripts) the new mount binds
to the initial kernel mount of devpts. This mode is referred to as the
'single-instance' mode and the current, single-instance semantics are
preserved, i.e PTYs are common across the system.
The only difference between this single-instance mode and the legacy mode
is the presence of new, '/dev/pts/ptmx' node with permissions 0000, which
can safely be ignored.
If CONFIG_DEVPTS_MULTIPLE_INSTANCES=y and 'newinstance' option is specified,
the mount is considered to be in the multi-instance mode and a new instance
of the devpts fs is created. Any ptys created in this instance are independent
of ptys in other instances of devpts. Like in the single-instance mode, the
/dev/pts/ptmx node is present. To effectively use the multi-instance mode,
open of /dev/ptmx must be a redirected to '/dev/pts/ptmx' using a symlink or
bind-mount.
Eg: A container startup script could do the following:
$ chmod 0666 /dev/pts/ptmx
$ rm /dev/ptmx
$ ln -s pts/ptmx /dev/ptmx
$ ns_exec -cm /bin/bash
# We are now in new container
$ umount /dev/pts
$ mount -t devpts -o newinstance lxcpts /dev/pts
$ sshd -p 1234
where 'ns_exec -cm /bin/bash' calls clone() with CLONE_NEWNS flag and execs
/bin/bash in the child process. A pty created by the sshd is not visible in
the original mount of /dev/pts.
As an option instead of placing a /dev/ptmx device node at /dev/ptmx
it is possible to place a symlink to /dev/pts/ptmx at /dev/ptmx or
to bind mount /dev/ptx/ptmx to /dev/ptmx. If you opt for using
the devpts filesystem in this manner devpts should be mounted with
the ptmxmode=0666, or chmod 0666 /dev/pts/ptmx should be called.
Total count of pty pairs in all instances is limited by sysctls:
kernel.pty.max = 4096 - global limit
kernel.pty.reserve = 1024 - reserve for initial instance
kernel.pty.reserve = 1024 - reserved for filesystems mounted from the initial mount namespace
kernel.pty.nr - current count of ptys
Per-instance limit could be set by adding mount option "max=<count>".
This feature was added in kernel 3.4 together with sysctl kernel.pty.reserve.
In kernels older than 3.4 sysctl kernel.pty.max works as per-instance limit.
User-space changes
------------------
In multi-instance mode (i.e '-o newinstance' mount option is specified at least
once), following user-space issues should be noted.
1. If -o newinstance mount option is never used, /dev/pts/ptmx can be ignored
and no change is needed to system-startup scripts.
2. To effectively use multi-instance mode (i.e -o newinstance is specified)
administrators or startup scripts should "redirect" open of /dev/ptmx to
/dev/pts/ptmx using either a bind mount or symlink.
$ mount -t devpts -o newinstance devpts /dev/pts
followed by either
$ rm /dev/ptmx
$ ln -s pts/ptmx /dev/ptmx
$ chmod 666 /dev/pts/ptmx
or
$ mount -o bind /dev/pts/ptmx /dev/ptmx
3. The '/dev/ptmx -> pts/ptmx' symlink is the preferred method since it
enables better error-reporting and treats both single-instance and
multi-instance mounts similarly.
But this method requires that system-startup scripts set the mode of
/dev/pts/ptmx correctly (default mode is 0000). The scripts can set the
mode by, either
- adding ptmxmode mount option to devpts entry in /etc/fstab, or
- using 'chmod 0666 /dev/pts/ptmx'
4. If multi-instance mode mount is needed for containers, but the system
startup scripts have not yet been updated, container-startup scripts
should bind mount /dev/ptmx to /dev/pts/ptmx to avoid breaking single-
instance mounts.
Or, in general, container-startup scripts should use:
mount -t devpts -o newinstance -o ptmxmode=0666 devpts /dev/pts
if [ ! -L /dev/ptmx ]; then
mount -o bind /dev/pts/ptmx /dev/ptmx
fi
When all devpts mounts are multi-instance, /dev/ptmx can permanently be
a symlink to pts/ptmx and the bind mount can be ignored.
5. A multi-instance mount that is not accompanied by the /dev/ptmx to
/dev/pts/ptmx redirection would result in an unusable/unreachable pty.
mount -t devpts -o newinstance lxcpts /dev/pts
immediately followed by:
open("/dev/ptmx")
would create a pty, say /dev/pts/7, in the initial kernel mount.
But /dev/pts/7 would be invisible in the new mount.
6. The permissions for /dev/pts/ptmx node should be specified when mounting
/dev/pts, using the '-o ptmxmode=%o' mount option (default is 0000).
mount -t devpts -o newinstance -o ptmxmode=0644 devpts /dev/pts
The permissions can be later be changed as usual with 'chmod'.
chmod 666 /dev/pts/ptmx
7. A mount of devpts without the 'newinstance' option results in binding to
initial kernel mount. This behavior while preserving legacy semantics,
does not provide strict isolation in a container environment. i.e by
mounting devpts without the 'newinstance' option, a container could
get visibility into the 'host' or root container's devpts.
To workaround this and have strict isolation, all mounts of devpts,
including the mount in the root container, should use the newinstance
option.

d_real: overlay/union type filesystems implement this method to return one of
the underlying dentries hidden by the overlay. It is used in three
different modes:
static char *pipefs_dname(struct dentry *dent, char *buffer, int buflen)

Called from file_dentry() it returns the real dentry matching the inode
argument. The real dentry may be from a lower layer already copied up,
but still referenced from the file. This mode is selected with a
non-NULL inode argument. This will always succeed.
With NULL inode and zero flags the topmost real underlying dentry is
returned. This will always succeed.
