The dma-buf subsystem provides the framework for sharing buffers

subsystems, and for synchronizing asynchronous hardware access.

</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.
