When we implement multiuser mounts, we'll need to filter filehandles by fsuid. Add a flag for multiuser mounts and code to filter by fsuid when it's set. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NSteve French <sfrench@us.ibm.com>

cifsFileInfo needs a pointer to a tcon, but it doesn't currently hold a reference to it. Change it to keep a pointer to a tcon_link instead and hold a reference to it. That will keep the tcon from being freed until the file is closed. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NSteve French <sfrench@us.ibm.com>

Eventually, we'll need to track the use of tcons on a per-sb basis, so that we know when it's ok to tear them down. Begin this conversion by adding a new "tcon_link" struct and accessors that get it. For now, the core data structures are untouched -- cifs_sb still just points to a single tcon and the pointers are just cast to deal with the accessor functions. A later patch will flesh this out.

Get a reference to the file early so we can eventually base the decision about signing on the correct tcon. If that doesn't work for some reason, then fall back to generic_writepages. That's just as likely to fail, but it simplifies the error handling. In truth, I'm not sure how that could occur anyway, so maybe a NULL open_file here ought to be a BUG()? After that, we drop the reference to the open_file and then we re-get one prior to each WriteAndX call. This helps ensure that the filehandle isn't held open any longer than necessary and that open files are reclaimed prior to each write call.

At mount time, we'll always need to create a tcon that will serve as a template for others that are associated with the mount. This tcon is known as the "master" tcon. In some cases, we'll need to use that tcon regardless of who's accessing the mount. Add an accessor function for the master tcon and go ahead and switch the appropriate places to use it.

When we convert cifs to do multiple sessions per mount, we'll need more than one tcon per superblock. At that point "cifs_sb->tcon" will make no sense. Add a new accessor function that gets a tcon given a cifs_sb. For now, it just returns cifs_sb->tcon. Later it'll do more.

Attribue Value (AV) pairs or Target Info (TI) pairs are part of ntlmv2 authentication. Structure ntlmv2_resp had only definition for two av pairs. So removed it, and now allocation of av pairs is dynamic. For servers like Windows 7/2008, av pairs sent by server in challege packet (type 2 in the ntlmssp exchange/negotiation) can vary. Server sends them during ntlmssp negotiation. So when ntlmssp is used as an authentication mechanism, type 2 challenge packet from server has this information. Pluck it and use the entire blob for authenticaiton purpose. If user has not specified, extract (netbios) domain name from the av pairs which is used to calculate ntlmv2 hash. Servers like Windows 7 are particular about the AV pair blob. Servers like Windows 2003, are not very strict about the contents of av pair blob used during ntlmv2 authentication. So when security mechanism such as ntlmv2 is used (not ntlmv2 in ntlmssp), there is no negotiation and so genereate a minimal blob that gets used in ntlmv2 authentication as well as gets sent. Fields tilen and tilbob are session specific. AV pair values are defined. To calculate ntlmv2 response we need ti/av pair blob. For sec mech like ntlmssp, the blob is plucked from type 2 response from the server. From this blob, netbios name of the domain is retrieved, if user has not already provided, to be included in the Target String as part of ntlmv2 hash calculations. For sec mech like ntlmv2, create a minimal, two av pair blob. The allocated blob is freed in case of error. In case there is no error, this blob is used in calculating ntlmv2 response (in CalcNTLMv2_response) and is also copied on the response to the server, and then freed. The type 3 ntlmssp response is prepared on a buffer, 5 * sizeof of struct _AUTHENTICATE_MESSAGE, an empirical value large enough to hold _AUTHENTICATE_MESSAGE plus a blob with max possible 10 values as part of ntlmv2 response and lmv2 keys and domain, user, workstation names etc. Also, kerberos gets selected as a default mechanism if server supports it, over the other security mechanisms.

Change name of variable mac_key to session key. The reason mac_key was changed to session key is, this structure does not hold message authentication code, it holds the session key (for ntlmv2, ntlmv1 etc.). mac is generated as a signature in cifs_calc* functions.

cifs_new_fileinfo() does not use the 'oplock' value from the callers. Instead, it sets it to REQ_OPLOCK which seems wrong. We should be using the oplock value obtained from the Server to set the inode's clientCanCacheAll or clientCanCacheRead flags. Fix this by passing oplock from the callers to cifs_new_fileinfo(). This change dates back to commit a6ce4932 (2.6.30-rc3). So, all the affected versions will need this fix. Please Cc stable once reviewed and accepted.

libata depends on scsi_host_template for module reference counting and sht's should be owned by each low level driver. During libahci split, the sht was left with libahci.ko leaving the actual low level drivers not reference counted. This made ahci and ahci_platform always unloadable even while they're being actively used. Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for each low level ahci driver. stable: only applicable to 2.6.35.

Commit e40cc4bd introduced a build breakage if CONFIG_SMP is undefined. This commit fixes the problem. This fix is only a workaround. For a real fix, cpu_sibling_mask() should be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be included directly. This fix is currently not possible because asm/smp.h defines cpu_sibling_mask() unconditionally and is included directly from many source files.

Fixes kernel bugzilla #16603 tcp_sendmsg() truncates iov_len to an 'int' which a 4GB write to write zero bytes, for example. There is also the problem higher up of how verify_iovec() works. It wants to prevent the total length from looking like an error return value. However it does this using 'int', but syscalls return 'long' (and thus signed 64-bit on 64-bit machines). So it could trigger false-positives on 64-bit as written. So fix it to use 'long'.

The PKT_CTRL_CMD_STATUS device ioctl retrieves a pointer to a pktcdvd_device from the global pkt_devs array. The index into this array is provided directly by the user and is a signed integer, so the comparison to ensure that it falls within the bounds of this array will fail when provided with a negative index. This can be used to read arbitrary kernel memory or cause a crash due to an invalid pointer dereference. This can be exploited by users with permission to open /dev/pktcdvd/control (on many distributions, this is readable by group "cdrom").
