2013-06-27[CIFS] Fix build warningSteve French1-1/+2
Fix build warning in Shirish's recent SMB3 signing patch which occurs when SMB2 support is disabled in Kconfig. fs/built-in.o: In function `cifs_setup_session': >> (.text+0xa1767): undefined reference to `generate_smb3signingkey' Pointed out by: automated 0-DAY kernel build testing backend Intel Open Source Technology Center CC: Shirish Pargaonkar <shirishpargaonkar@gmail.com> Signed-off-by: Steve French <smfrench@gmail.com>
2013-06-26[CIFS] SMB3 Signing enablementSteve French1-0/+1
SMB3 uses a much faster method of signing (which is also better in other ways), AES-CMAC. With the kernel now supporting AES-CMAC since last release, we are overdue to allow SMB3 signing (today only CIFS and SMB2 and SMB2.1, but not SMB3 and SMB3.1 can sign) - and we need this also for checking secure negotation and also per-share encryption (two other new SMB3 features which we need to implement). This patch needs some work in a few areas - for example we need to move signing for SMB2/SMB3 from per-socket to per-user (we may be able to use the "nosharesock" mount option in the interim for the multiuser case), and Shirish found a bug in the earlier authentication overhaul (setting signing flags properly) - but those can be done in followon patches.

2013-06-24move sectype to the cifs_ses instead of TCP_Server_InfoJeff Layton1-84/+33
Now that we track what sort of NEGOTIATE response was received, stop mandating that every session on a socket use the same type of auth. Push that decision out into the session setup code, and make the sectype a per-session property. This should allow us to mix multiple sectypes on a socket as long as they are compatible with the NEGOTIATE response. With this too, we can now eliminate the ses->secFlg field since that info is redundant and harder to work with than a securityEnum.

2013-06-24cifs: track the enablement of signing in the TCP_Server_InfoJeff Layton1-9/+3
Currently, we determine this according to flags in the sec_mode, flags in the global_secflags and via other methods. That makes the semantics very hard to follow and there are corner cases where we don't handle this correctly. Add a new bool to the TCP_Server_Info that acts as a simple flag to tell us whether signing is enabled on this connection or not, and fix up the places that need to determine this to use that flag. This is a bit weird for the SMB2 case, where signing is per-session. SMB2 needs work in this area already though. The existing SMB2 code has similar logic to what we're using here, so there should be no real change in behavior. These changes should make it easier to implement per-session signing in the future though.

Add a new mount option to work around this behavior that forces a mount request to open a new socket to the server instead of reusing an existing one.

2013-05-31cifs: fix off-by-one bug in build_unc_path_to_rootJeff Layton1-2/+2
commit 839db3d10a (cifs: fix up handling of prefixpath= option) changed the code such that the vol->prepath no longer contained a leading delimiter and then fixed up the places that accessed that field to account for that change. One spot in build_unc_path_to_root was missed however. When doing the pointer addition on pos, that patch failed to account for the fact that we had already incremented "pos" by one when adding the length of the prepath. This caused a buffer overrun by one byte. This patch fixes the problem by correcting the handling of "pos".

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull user namespace and namespace infrastructure changes from Eric W Biederman: "This set of changes starts with a few small enhnacements to the user namespace. reboot support, allowing more arbitrary mappings, and support for mounting devpts, ramfs, tmpfs, and mqueuefs as just the user namespace root. I do my best to document that if you care about limiting your unprivileged users that when you have the user namespace support enabled you will need to enable memory control groups. There is a minor bug fix to prevent overflowing the stack if someone creates way too many user namespaces. The bulk of the changes are a continuation of the kuid/kgid push down work through the filesystems. These changes make using uids and gids typesafe which ensures that these filesystems are safe to use when multiple user namespaces are in use. The filesystems converted for 3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The changes for these filesystems were a little more involved so I split the changes into smaller hopefully obviously correct changes. XFS is the only filesystem that remains. I was hoping I could get that in this release so that user namespace support would be enabled with an allyesconfig or an allmodconfig but it looks like the xfs changes need another couple of days before it they are ready." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (93 commits) cifs: Enable building with user namespaces enabled. cifs: Convert struct cifs_ses to use a kuid_t and a kgid_t cifs: Convert struct cifs_sb_info to use kuids and kgids cifs: Modify struct smb_vol to use kuids and kgids cifs: Convert struct cifsFileInfo to use a kuid cifs: Convert struct cifs_fattr to use kuid and kgids cifs: Convert struct tcon_link to use a kuid. cifs: Modify struct cifs_unix_set_info_args to hold a kuid_t and a kgid_t cifs: Convert from a kuid before printing current_fsuid cifs: Use kuids and kgids SID to uid/gid mapping cifs: Pass GLOBAL_ROOT_UID and GLOBAL_ROOT_GID to keyring_alloc cifs: Use BUILD_BUG_ON to validate uids and gids are the same size cifs: Override unmappable incoming uids and gids nfsd: Enable building with user namespaces enabled. nfsd: Properly compare and initialize kuids and kgids nfsd: Store ex_anon_uid and ex_anon_gid as kuids and kgids nfsd: Modify nfsd4_cb_sec to use kuids and kgids nfsd: Handle kuids and kgids in the nfs4acl to posix_acl conversion nfsd: Convert nfsxdr to use kuids and kgids nfsd: Convert nfs3xdr to use kuids and kgids ...

Then, fix up the users of the prepath option to prefix it with the correct delimiter when they use it. Also, there's no need to limit the length of the prefixpath to 1k.

We later copy this into the tcon->treeName, for instance and it's a lot shorter than 300 bytes. Eliminate an extra kmalloc and copy as well. Just set the vol->UNC directly with the contents of match_strdup. Establish that the UNC should be stored with '\\' delimiters. Use convert_delimiter to change it in place in the vol->UNC.
