The CIFS VFS support for Linux supports many advanced network filesystem

This module supports the SMB3 family of advanced network protocols (as well

The CIFS VFS module for Linux supports many advanced network filesystem
features such as hierarchical DFS like namespace, hardlinks, locking and more.
It was designed to comply with the SNIA CIFS Technical Reference (which
supersedes the 1992 X/Open SMB Standard) as well as to perform best practice
practical interoperability with Windows 2000, Windows XP, Samba and equivalent
servers. This code was developed in participation with the Protocol Freedom

For Linux 2.4:
1) Get the kernel source (e.g.from http://www.kernel.org)
and download the cifs vfs source (see the project page
at http://us1.samba.org/samba/Linux_CIFS_client.html)
and change directory into the top of the kernel directory
then patch the kernel (e.g. "patch -p1 < cifs_24.patch")
to add the cifs vfs to your kernel configure options if
it has not already been added (e.g. current SuSE and UL
users do not need to apply the cifs_24.patch since the cifs vfs is
already in the kernel configure menu) and then
mkdir linux/fs/cifs and then copy the current cifs vfs files from
the cifs download to your kernel build directory e.g.
cp <cifs_download_dir>/fs/cifs/* to <kernel_download_dir>/fs/cifs
2) make menuconfig (or make xconfig)

To improve security the SMB2.1 dialect or later (usually will get SMB3) is now
the new default. To use old dialects (e.g. to mount Windows XP) use "vers=1.0"
on mount (or vers=2.0 for Windows Vista). Note that the CIFS (vers=1.0) is
much older and less secure than the default dialect SMB3 which includes
many advanced security features such as downgrade attack detection
and encrypted shares and stronger signing and authentication algorithms.
There are additional mount options that may be helpful for SMB3 to get
improved POSIX behavior (NB: can use vers=3.0 to force only SMB3, never 2.1):

extra copy in/out of the socket buffers in some cases.

Sysctls
=======
Seccomp's sysctl files can be found in the ``/proc/sys/kernel/seccomp/``
directory. Here's a description of each file in that directory:
``actions_avail``:
A read-only ordered list of seccomp return values (refer to the
``SECCOMP_RET_*`` macros above) in string form. The ordering, from
left-to-right, is the least permissive return value to the most
permissive return value.
The list represents the set of seccomp return values supported
by the kernel. A userspace program may use this list to
determine if the actions found in the ``seccomp.h``, when the
program was built, differs from the set of actions actually
supported in the current running kernel.
``actions_logged``:
A read-write ordered list of seccomp return values (refer to the
``SECCOMP_RET_*`` macros above) that are allowed to be logged. Writes
to the file do not need to be in ordered form but reads from the file
will be ordered in the same way as the actions_avail sysctl.
It is important to note that the value of ``actions_logged`` does not
prevent certain actions from being logged when the audit subsystem is
configured to audit a task. If the action is not found in
``actions_logged`` list, the final decision on whether to audit the
action for that task is ultimately left up to the audit subsystem to
decide for all seccomp return values other than ``SECCOMP_RET_ALLOW``.
The ``allow`` string is not accepted in the ``actions_logged`` sysctl
as it is not possible to log ``SECCOMP_RET_ALLOW`` actions. Attempting
to write ``allow`` to the sysctl will result in an EINVAL being
returned.
