| | | | | | | | | | | | | + Set a handler for the witness notification messages received from the userspace daemon. + Handle the resource state change notification. When the resource becomes unavailable or available set the tcp status to CifsNeedReconnect for all channels.

* cifs: Send witness register and unregister commands to userspace daemonSamuel Cabrero2020-12-141-0/+15
| | | | | | | | | | | | | | | | | | | | | + Define the generic netlink family commands and message attributes to communicate with the userspace daemon + The register and unregister commands are sent when connecting or disconnecting a tree. The witness registration keeps a pointer to the tcon and has the same lifetime. + Each registration has an id allocated by an IDR. This id is sent to the userspace daemon in the register command, and will be included in the notification messages from the userspace daemon to retrieve from the IDR the matching registration. + The authentication information is bundled in the register message. If kerberos is used the message just carries a flag.

* License cleanup: add SPDX license identifier to uapi header files with a licenseGreg Kroah-Hartman2017-11-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

* cifs: Move and expand MAX_SERVER_SIZE definitionScott Lovenberg2013-09-081-0/+1
| | | | | | | | | | MAX_SERVER_SIZE has been moved to cifs_mount.h and renamed CIFS_NI_MAXHOST for clarity. It has been expanded to 1024 as the previous value of 16 was very short.

* cifs: Expand max share name length to 256Scott Lovenberg2013-09-081-1/+2
| | | | | | | | | | The old max share name length limit was 80 due to Windows NET SHARE command not allowing more than that. However, share names can be much longer. This is a more reasonable maximum share name length.

* cifs: Move string length definitions to uapiScott Lovenberg2013-09-081-0/+25
The max string length definitions for user name, domain name, password, and share name have been moved into their own header file in uapi so the mount helper can use autoconf to define them instead of keeping the kernel side and userland side definitions in sync manually. The names have also been standardized with a "CIFS" prefix and "LEN" suffix.
