The CIFS protocol is fully supported by + file servers such as Windows 2000 (including Windows 2003, NT 4 + and Windows XP) as well by Samba (which provides excellent CIFS + server support for Linux and many other operating systems). Limited + support for OS/2 and Windows ME and similar servers is provided as + well. + + The cifs module provides an advanced network file system + client for mounting to CIFS compliant servers. It includes + support for DFS (hierarchical name space), secure per-user + session establishment via Kerberos or NTLM or NTLMv2, + safe distributed caching (oplock), optional packet + signing, Unicode and other internationalization improvements. + If you need to mount to Samba or Windows from this machine, say Y. + +config CIFS_STATS + bool "CIFS statistics" + depends on CIFS + help + Enabling this option will cause statistics for each server share + mounted by the cifs client to be displayed in /proc/fs/cifs/Stats + +config CIFS_STATS2 + bool "Extended statistics" + depends on CIFS_STATS + help + Enabling this option will allow more detailed statistics on SMB + request timing to be displayed in /proc/fs/cifs/DebugData and also + allow optional logging of slow responses to dmesg (depending on the + value of /proc/fs/cifs/cifsFYI, see fs/cifs/README for more details). + These additional statistics may have a minor effect on performance + and memory utilization. + + Unless you are a developer or are doing network performance analysis + or tuning, say N. + +config CIFS_WEAK_PW_HASH + bool "Support legacy servers which use weaker LANMAN security" + depends on CIFS + help + Modern CIFS servers including Samba and most Windows versions + (since 1997) support stronger NTLM (and even NTLMv2 and Kerberos) + security mechanisms. These hash the password more securely + than the mechanisms used in the older LANMAN version of the + SMB protocol but LANMAN based authentication is needed to + establish sessions with some old SMB servers. + + Enabling this option allows the cifs module to mount to older + LANMAN based servers such as OS/2 and Windows 95, but such + mounts may be less secure than mounts using NTLM or more recent + security mechanisms if you are on a public network. Unless you + have a need to access old SMB servers (and are on a private + network) you probably want to say N. Even if this support + is enabled in the kernel build, LANMAN authentication will not be + used automatically. At runtime LANMAN mounts are disabled but + can be set to required (or optional) either in + /proc/fs/cifs (see fs/cifs/README for more detail) or via an + option on the mount command.

CIFS maps the name of + extended attributes beginning with the user namespace prefix + to SMB/CIFS EAs. EAs are stored on Windows servers without the + user namespace prefix, but their names are seen by Linux cifs clients + prefaced by the user namespace prefix. The system namespace + (used by some filesystems to store ACLs) is not supported at + this time. + + If unsure, say N. + +config CIFS_POSIX + bool "CIFS POSIX Extensions" + depends on CIFS_XATTR + help + Enabling this option will cause the cifs client to attempt to + negotiate a newer dialect with servers, such as Samba 3.0.5 + or later, that optionally can handle more POSIX like (rather + than Windows like) file behavior. It also enables + support for POSIX ACLs (getfacl and setfacl) to servers + (such as Samba 3.10 and later) which can negotiate + CIFS POSIX ACL support. If unsure, say N. + +config CIFS_DEBUG2 + bool "Enable additional CIFS debugging routines" + depends on CIFS + help + Enabling this option adds a few more debugging routines + to the cifs code which slightly increases the size of + the cifs module and can cause additional logging of debug + messages in some error paths, slowing performance. This + option can be turned off unless you are debugging + cifs problems.

This feature also enables + an upcall mechanism for CIFS which contacts userspace helper + utilities to provide server name resolution (host names to + IP addresses) which is needed for implicit mounts of DFS junction + points.
