2019-09-21smb3: allow decryption keys to be dumped by admin for debuggingSteve French1-0/+29
In order to debug certain problems it is important to be able to decrypt network traces (e.g. wireshark) but to do this we need to be able to dump out the encryption/decryption keys. Dumping them to an ioctl is safer than dumping then to dmesg, (and better than showing all keys in a pseudofile). Restrict this to root (CAP_SYS_ADMIN), and only for a mount that this admin has access to. Sample smbinfo output: SMB3.0 encryption Session Id: 0x82d2ec52 Session Key: a5 6d 81 d0 e c1 ca e1 d8 13 aa 20 e8 f2 cc 71 Server Encryption Key: 1a c3 be ba 3d fc dc 3c e bc 93 9e 50 9e 19 c1 Server Decryption Key: e0 d4 d9 43 1b a2 1b e3 d8 76 77 49 56 f7 20 88 Reviewed-by: Aurelien Aptel <aaptel@suse.com> Pavel Shilovsky <pshilov@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2018-10-24cifs: add support for ioctl on directoriesRonnie Sahlberg1-9/+34
We do not call cifs_open_file() for directories and thus we do not have a pSMBFile we can extract the FIDs from.

Remove the CONFIG_CIFS_SMB2 ifdef and Kconfig option since they must always be on now. For various security reasons, SMB3 and later are STRONGLY preferred over CIFS and older dialects, and SMB3 (and later) will now be the default dialects so we do not want to allow them to be ifdeffed out.

2017-04-28Do not return number of bytes written for ioctl CIFS_IOC_COPYCHUNK_FILESachin Prabhu1-1/+2
commit 620d8745b35d ("Introduce cifs_copy_file_range()") changes the behaviour of the cifs ioctl call CIFS_IOC_COPYCHUNK_FILE. In case of successful writes, it now returns the number of bytes written. This return value is treated as an error by the xfstest cifs/001. Depending on the errno set at that time, this may or may not result in the test failing. The patch fixes this by setting the return value to 0 in case of successful writes.

2017-04-07Introduce cifs_copy_file_range()Sachin Prabhu1-58/+2
The earlier changes to copy range for cifs unintentionally disabled the more common form of server side copy. The patch introduces the file_operations helper cifs_copy_file_range() which is used by the syscall copy_file_range. The new file operations helper allows us to perform server side copies for SMB2.0 and 2.1 servers as well as SMB 3.0+ servers which do not support the ioctl FSCTL_DUPLICATE_EXTENTS_TO_FILE. The new helper uses the ioctl FSCTL_SRV_COPYCHUNK_WRITE to perform server side copies. The helper is called by vfs_copy_file_range() only once an attempt to clone the file using the ioctl FSCTL_DUPLICATE_EXTENTS_TO_FILE has failed.

2015-12-08vfs: pull btrfs clone API to vfs layerChristoph Hellwig1-67/+59
The btrfs clone ioctls are now adopted by other file systems, with NFS and CIFS already having support for them, and XFS being under active development. To avoid growth of various slightly incompatible implementations, add one to the VFS. Note that clones are different from file copies in several ways: - they are atomic vs other writers - they support whole file clones - they support 64-bit legth clones - they do not allow partial success (aka short writes) - clones are expected to be a fast metadata operation Because of that it would be rather cumbersome to try to piggyback them on top of the recent clone_file_range infrastructure. The converse isn't true and the clone_file_range system call could try clone file range as a first attempt to copy, something that further patches will enable. Based on earlier work from Peng Tao.

2015-11-09Allow copy offload (CopyChunk) across sharesSteve French1-3/+8
FSCTL_SRV_COPYCHUNK_WRITE only requires that the source and target be on the same server (not the same volume or same share), so relax the existing check (which required them to be on the same share). Note that this works to Windows (and presumably most other NAS) but Samba requires that the source and target be on the same share.

This FSCTL was added in the SMB3.11 dialect (testing was against REFS file system) so have put it as a 3.11 protocol specific operation ("vers=3.1.1" on the mount). Tested at the SMB3 plugfest in Redmond. It depends on the new FS Attribute (BLOCK_REFCOUNTING) which is used to advertise support for the ability to do this ioctl (if you can support multiple files pointing to the same block than this refcounting ability or equivalent is needed to support the new reflink-like duplicate extent SMB3 ioctl.

2015-01-19fix deadlock in cifs_ioctl_clone()Al Viro1-16/+5
It really needs to check that src is non-directory *and* use {un,}lock_two_nodirectories(). As it is, it's trivial to cause double-lock (ioctl(fd, CIFS_IOC_COPYCHUNK_FILE, fd)) and if the last argument is an fd of directory, we are asking for trouble by violating the locking order - all directories go before all non-directories. If the last argument is an fd of parent directory, it has 50% odds of locking child before parent, which will cause AB-BA deadlock if we race with unlink().

2013-11-25[CIFS] Do not use btrfs refcopy ioctl for SMB2 copy offloadSteve French1-2/+4
Change cifs.ko to using CIFS_IOCTL_COPYCHUNK instead of BTRFS_IOC_CLONE to avoid confusion about whether copy-on-write is required or optional for this operation. SMB2/SMB3 copyoffload had used the BTRFS_IOC_CLONE ioctl since they both speed up copy by offloading the copy rather than passing many read and write requests back and forth and both have identical syntax (passing file handles), but for SMB2/SMB3 CopyChunk the server is not required to use copy-on-write to make a copy of the file (although some do), and Christoph has commented that since CopyChunk does not require copy-on-write we should not reuse BTRFS_IOC_CLONE. This patch renames the ioctl to use a cifs specific IOCTL CIFS_IOCTL_COPYCHUNK. This ioctl is particularly important for SMB2/SMB3 since large file copy over the network otherwise can be very slow, and with this is often more than 100 times faster putting less load on server and client. Note that if a copy syscall is ever introduced, depending on its requirements/format it could end up using one of the other three methods that CIFS/SMB2/SMB3 can do for copy offload, but this method is particularly useful for file copy and broadly supported (not just by Samba server).

2013-11-14CIFS: SMB2/SMB3 Copy offload support (refcopy) phase 1Steve French1-0/+111
This first patch adds the ability for us to do a server side copy (ie fast copy offloaded to the server to perform, aka refcopy) "cp --reflink" of one file to another located on the same server. This is much faster than traditional copy (which requires reading and writing over the network and extra memcpys). This first version is not going to be copy files larger than about 1MB (to Samba) until I add support for multiple chunks and for autoconfiguring the chunksize. It includes: 1) processing of the ioctl 2) marshalling and sending the SMB2/SMB3 fsctl over the network 3) simple parsing of the response It does not include yet (these will be in followon patches to come soon): 1) support for multiple chunks 2) support for autoconfiguring and remembering the chunksize 3) Support for the older style copychunk which Samba 4.1 server supports (because this requires write permission on the target file, which cp does not give you, apparently per-posix). This may require a distinct tool (other than cp) and other ioctl to implement. Reviewed-by: Pavel Shilovsky <piastry@etersoft.ru> Signed-off-by: Steve French <smfrench@gmail.com>
