CIFS was the successor - to the original dialect, the Server Message Block (SMB) protocol, the - native file sharing mechanism for most early PC operating systems. - - The SMB3 protocol is supported by most modern operating systems - and NAS appliances (e.g. Samba, Windows 10, Windows Server 2016, - MacOS) and even in the cloud (e.g. Microsoft Azure). - The older CIFS protocol was included in Windows NT4, 2000 and XP (and - later) as well by Samba (which provides excellent CIFS and SMB3 - server support for Linux and many other operating systems). Use of - dialects older than SMB2.1 is often discouraged on public networks. - This module also provides limited support for OS/2 and Windows ME - and similar very old servers. - - This module provides an advanced network file system client - for mounting to SMB3 (and CIFS) compliant servers. It includes - support for DFS (hierarchical name space), secure per-user - session establishment via Kerberos or NTLM or NTLMv2, RDMA - (smbdirect), advanced security features, per-share encryption, - directory leases, safe distributed caching (oplock), optional packet - signing, Unicode and other internationalization improvements. - - In general, the default dialects, SMB3 and later, enable better - performance, security and features, than would be possible with CIFS. - Note that when mounting to Samba, due to the CIFS POSIX extensions, - CIFS mounts can provide slightly better POSIX compatibility - than SMB3 mounts. SMB2/SMB3 mount options are also - slightly simpler (compared to CIFS) due to protocol improvements. - - If you need to mount to Samba, Azure, Macs or Windows from this machine, say Y. - -config CIFS_STATS2 - bool "Extended statistics" - depends on CIFS - default y - 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 Documentation/admin-guide/cifs/usage.rst - for more details. These additional statistics may have a minor effect - on performance and memory utilization. - - If unsure, say Y. - -config CIFS_ALLOW_INSECURE_LEGACY - bool "Support legacy servers which use less secure dialects" - depends on CIFS - default y - help - Modern dialects, SMB2.1 and later (including SMB3 and 3.1.1), have - additional security features, including protection against - man-in-the-middle attacks and stronger crypto hashes, so the use - of legacy dialects (SMB1/CIFS and SMB2.0) is discouraged. - - Disabling this option prevents users from using vers=1.0 or vers=2.0 - on mounts with cifs.ko - - If unsure, say Y. - -config CIFS_UPCALL - bool "Kerberos/SPNEGO advanced session setup" - depends on CIFS - help - Enables an upcall mechanism for CIFS which accesses userspace helper - utilities to provide SPNEGO packaged (RFC 4178) Kerberos tickets - which are needed to mount to certain secure servers (for which more - secure Kerberos authentication is required). If unsure, say Y. - -config CIFS_XATTR - bool "CIFS extended attributes" - depends on CIFS - help - Extended attributes are name:value pairs associated with inodes by - the kernel or by users (see the attr(5) manual page for details). - 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 Y. - -config CIFS_POSIX - bool "CIFS POSIX Extensions" - depends on CIFS && CIFS_ALLOW_INSECURE_LEGACY && 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_DEBUG - bool "Enable CIFS debugging routines" - default y - depends on CIFS - help - Enabling this option adds helpful debugging messages to - the cifs code which increases the size of the cifs module. - If unsure, say Y. - -config CIFS_DEBUG2 - bool "Enable additional CIFS debugging routines" - depends on CIFS_DEBUG - 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. If unsure, say N. - -config CIFS_DEBUG_DUMP_KEYS - bool "Dump encryption keys for offline decryption (Unsafe)" - depends on CIFS_DEBUG - help - Enabling this will dump the encryption and decryption keys - used to communicate on an encrypted share connection on the - console. This allows Wireshark to decrypt and dissect - encrypted network captures. Enable this carefully. - If unsure, say N. - -config CIFS_DFS_UPCALL - bool "DFS feature support" - depends on CIFS - help - Distributed File System (DFS) support is used to access shares - transparently in an enterprise name space, even if the share - moves to a different server. 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 in order to reconnect to - servers if their addresses change or for implicit mounts of - DFS junction points. If unsure, say Y. - -config CIFS_SWN_UPCALL - bool "SWN feature support" - depends on CIFS - help - The Service Witness Protocol (SWN) is used to get notifications - from a highly available server of resource state changes. This - feature enables an upcall mechanism for CIFS which contacts a - userspace daemon to establish the DCE/RPC connection to retrieve - the cluster available interfaces and resource change notifications. - If unsure, say Y. - -config CIFS_NFSD_EXPORT - bool "Allow nfsd to export CIFS file system" - depends on CIFS && BROKEN - help - Allows NFS server to export a CIFS mounted share (nfsd over cifs) - -config CIFS_SMB_DIRECT - bool "SMB Direct support" - depends on CIFS=m && INFINIBAND && INFINIBAND_ADDR_TRANS || CIFS=y && INFINIBAND=y && INFINIBAND_ADDR_TRANS=y - help - Enables SMB Direct support for SMB 3.0, 3.02 and 3.1.1. - SMB Direct allows transferring SMB packets over RDMA.
