genetlink: start to validate reserved header bytes

2022-08-29T11:47:15+00:00

We had historically not checked that genlmsghdr.reserved is 0 on input which prevents us from using those precious bytes in the future. One use case would be to extend the cmd field, which is currently just 8 bits wide and 256 is not a lot of commands for some core families. To make sure that new families do the right thing by default put the onus of opting out of validation on existing families.

cifs: Constify static struct genl_ops

2021-06-21T02:28:16+00:00

The only usage of cifs_genl_ops[] is to assign its address to the ops field in the genl_family struct, which is a pointer to const. Make it const to allow the compiler to put it in read-only memory.

cifs: Send witness register and unregister commands to userspace daemon

2020-12-14T15:16:22+00:00

+ 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. Signed-off-by: Samuel Cabrero Reviewed-by: Aurelien Aptel Signed-off-by: Steve French
