I'm not sure why this was merged with this flag hardcoded on, but it seems quite dangerous. Turn it off. Also, mount.cifs hands unrecognized options off to the kernel so there should be no need for changes there in order to support this. Signed-off-by:

Right now, there's no clear separation between the uid that owns the credentials used to do the mount and the overriding owner of the files on that mount. Add a separate cred_uid field that is set to the real uid of the mount user. Unlike the linux_uid, the uid= option does not override this parameter. The parm is sent to cifs.upcall, which can then preferentially use the creduid= parm instead of the uid= parm for finding credentials. This is not the only way to solve this. We could try to do all of this in kernel instead by having a module parameter that affects what gets passed in the uid= field of the upcall. That said, we have a lot more flexibility to change things in userspace so I think it probably makes sense to do it this way. Signed-off-by:

Add a mount option 'fsc' to enable local caching on CIFS. I considered adding a separate debug bit for caching, but it appears that debugging would be relatively easier with the normal CIFS_INFO level. As the cifs-utils (userspace) changes are not done yet, this patch enables 'fsc' by default to enable testing. Signed-off-by:

Define inode-level data storage objects (managed by cifsInodeInfo structs). Each inode-level object is created in a super-block level object and is itself a data storage object in to which pages from the inode are stored. The inode object is keyed by UniqueId. The coherency data being used is LastWriteTime, LastChangeTime and end of file reported by the server. Signed-off-by:

Define superblock-level cache index objects (managed by cifsTconInfo structs). Each superblock object is created in a server-level index object and in itself an index into which inode-level objects are inserted. The superblock object is keyed by sharename. The UniqueId/IndexNumber is used to validate that the exported share is the same since we accessed it last time. Signed-off-by:

This patch replaces the earlier patch by the same name. The only difference is that MAX_PASSWORD_SIZE has been increased to attempt to match the limits that windows enforces. Do a better job of matching sessions by authtype. Matching by username for a Kerberos session is incorrect, and anonymous sessions need special handling. Also, in the case where we do match by username, we also need to match by password. That ensures that someone else doesn't "borrow" an existing session without needing to know the password. Finally, passwords can be longer than 16 bytes. Bump MAX_PASSWORD_SIZE to 512 to match the size that the userspace mount helper allows. Signed-off-by:

Move the address comparator out of cifs_find_tcp_session and into a separate function for cleanliness. Also change the argument to that function to a "struct sockaddr" pointer. Passing pointers to sockaddr_storage is a little odd since that struct is generally for declaring static storage. Signed-off-by:

This patch should replace the patch I sent a couple of weeks ago to set the port in cifs_convert_address. Currently we set this in cifs_find_tcp_session, but that's more of a side effect than anything. Add a new function called cifs_fill_sockaddr. Have it call cifs_convert_address and then set the port. This also allows us to skip passing in the port as a separate parm to cifs_find_tcp_session. Also, change cifs_convert_address take a struct sockaddr * rather than void * to make it clearer how this function should be called. Signed-off-by:

Define server-level cache index objects (as managed by TCP_ServerInfo structs) and register then with FS-Cache. Each server object is created in the CIFS top-level index object and is itself an index into which superblock-level objects are inserted. The server objects are now keyed by {IPaddress,family,port} tuple. Signed-off-by: -

Some platforms gate the pclk (APB - the bus - clock) to the peripherals for power saving, along with the functional clock. When devices are accessed without pclk enabled, the kernel will oops. This gives them two options: 1. Leave all clocks on all the time. 2. Attempt to gate pclk along with the functional clock. (With some hardware, pclk and the functional clock are gated by a single bit in a register.) (1) has the disadvantage that it causes increased power usage, which is bad news for battery operated devices. (2) can lead to kernel oops if registers are accessed without the functional clock being enabled. So, introduce the apb_pclk signal in such a way existing drivers don't need to be updated. Essentially, this means we guarantee that: 1. pclk will be enabled whenever the driver is bound to a device - from probe() to remove() time. 2. pclk will also be enabled when reading the primecell IDs from the device. In order to allow drivers to be incrementally updated to achieve greater power savings, we provide two additional calls to allow drivers to manage the pclk - amba_pclk_enable()/amba_pclk_disable().
