2010-08-26Cannot allocate memory error on mountSuresh Jayaraman1-1/+1

If I try with a bad password or with some other username (userbar), it fails with "Permission denied" as expected. If I try to mount as username = administrator, and give the correct administrator password, I would also expect "Permission denied", but I see "Cannot allocate memory" instead. > ýfs/cifs/netmisc.c: Mapping smb error code 5 to POSIX err -13 > ýfs/cifs/cifssmb.c: Send error in QPathInfo = -13 > ýCIFS VFS: cifs_read_super: get root inode failed Looks like the commit 0b8f18e3 assumed that cifs_get_inode_info() and friends fail only due to memory allocation error when the inode is NULL which is not the case if CIFSSMBQPathInfo() fails and returns an error.

2010-08-09cifs: truncate falloutChristoph Hellwig1-23/+7
Remove the calls to inode_newsize_ok given that we already did it as part of inode_change_ok in the beginning of cifs_setattr_(no)unix. No need to call ->truncate if cifs doesn't have one, so remove the explicit call in cifs_vmtruncate, and replace the calls to vmtruncate with truncate_setsize which is vmtruncate minus inode_newsize_ok and the call to ->truncate. Rename cifs_vmtruncate to cifs_setsize to match the new calling conventions. Question 1: why does cifs do the pagecache munging and i_size update twice for each setattr call, once opencoded in cifs_vmtruncate, and once using the VFS helpers? Question 2: what is supposed to be protected by i_lock in cifs_vmtruncate? Do we need it around the call to inode_change_ok?

In a few cases it was obvious that we would never end up calling vmtruncate so it was left out in the opencoded variant: spufs: explicitly checks for ATTR_SIZE earlier btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above In addition to that ncpfs called inode_setattr with handcrafted iattrs, which allowed to trim down the opencoded variant.

2010-08-05DNS: Separate out CIFS DNS Resolver codeWang Lei4-205/+56
Separate out the DNS resolver key type from the CIFS filesystem into its own module so that it can be made available for general use, including the AFS filesystem module. This facility makes it possible for the kernel to upcall to userspace to have it issue DNS requests, package up the replies and present them to the kernel in a useful form. The kernel is then able to cache the DNS replies as keys can be retained in keyrings. Resolver keys are of type "dns_resolver" and have a case-insensitive description that is of the form "[<type>:]<domain_name>". The optional <type> indicates the particular DNS lookup and packaging that's required. The <domain_name> is the query to be made. If <type> isn't given, a basic hostname to IP address lookup is made, and the result is stored in the key in the form of a printable string consisting of a comma-separated list of IPv4 and IPv6 addresses. This key type is supported by userspace helpers driven from /sbin/request-key and configured through /etc/request-key.conf. The cifs.upcall utility is invoked for UNC path server name to IP address resolution. The CIFS functionality is encapsulated by the dns_resolve_unc_to_ip() function, which is used to resolve a UNC path to an IP address for CIFS filesystem. This part remains in the CIFS module for now. See the added Documentation/networking/dns_resolver.txt for more information.

2010-08-05cifs: reduce false positives with inode aliasing serverino autodisableJeff Layton1-12/+31
It turns out that not all directory inodes with dentries on the i_dentry list are unusable here. We only consider them unusable if they are still hashed or if they have a root dentry attached. Full disclosure -- this check is inherently racy. There's nothing that stops someone from slapping a new dentry onto this inode just after this check, or hashing an existing one that's already attached. So, this is really a "best effort" thing to work around misbehaving servers. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2010-08-02cifs: add separate cred_uid field to sesInfoJeff Layton3-3/+10
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.

2010-08-02cifs: clean up cifs_find_smb_ses (try #2)Jeff Layton2-9/+19
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.

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.
