2008-12-26cifs: have calc_lanman_hash take more granular argsJeff Layton1-16/+14
cifs: have calc_lanman_hash take more granular args We need to use this routine to encrypt passwords associated with the tcon too. Don't assume that the password will be attached to the smb_session. Also, make some of the values in the lower encryption functions const since they aren't changed. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
2008-08-27[CIFS] Fix plaintext authenticationSteve French1-0/+1
The last eight bytes of the password field were not cleared when doing lanman plaintext password authentication. This patch fixes that. I tested it with Samba by setting password encryption to no in the server's smb.conf. Other servers also can be configured to force plaintext authentication. Note that plaintexti authentication requires setting /proc/fs/cifs/SecurityFlags to 0x30030 on the client (enabling both LANMAN and also plaintext password support). Also note that LANMAN support (and thus plaintext password support) requires CONFIG_CIFS_WEAK_PW_HASH to be enabled in menuconfig.

This should be the last big batch of whitespace/formatting fixes. checkpatch warnings for the cifs directory are down about 90% and many of the remaining ones are harder to remove or make the code harder to read. Signed-off-by: Steve French <sfrench@us.ibm.com>

2006-12-08[CIFS] Fix NTLMv2 mounts to Windows serversSteve French1-1/+3
Windows servers are pickier about NTLMv2 than Samba. This enables more secure mounts to Windows (not just Samba) ie when "sec=ntlmv2" is specified on the mount. Signed-off-by: Steve French <sfrench@us.ibm.com>

2006-06-08[CIFS] NTLMv2 support part 5Steve French1-19/+41
NTLMv2 authentication (stronger authentication than default NTLM) which many servers support now works. There was a problem with the construction of the security blob in the older code. Currently requires /proc/fs/cifs/Experimental to be set to 2 and /proc/fs/cifs/SecurityFlags to be set to 0x4004 (to require using NTLMv2 instead of default of NTLM) Next we will check signing to make sure optional NTLMv2 packet signing also works.

2006-03-31[CIFS] Incorrect signature sent on SMB ReadSteve French1-13/+23
Fixes Samba bug 3621 and kernel.org bug 6147 For servers which require SMB/CIFS packet signing, we were sending the wrong signature (all zeros) on SMB Read request. The new cifs routine to do signatures across an iovec was not complete - and SMB Read, unlike the new SMBWrite2, did not fall back to the older routine (ie use SendReceive vs. the more efficient SendReceive2 ie used the older cifs_sign_smb vs. the disabled cifs_sign_smb2) for calculating signatures. This finishes up cifs_sign_smb2/cifs_calc_signature2 so that the callers of SendReceive2 can get SMB/CIFS packet signatures. Now that cifs_sign_smb2 is supported, we could start using it in the write path but this smaller fix does not include the change to use SMBWrite2 when signatures are required (which when enabled will make more Writes more efficient and alloc less memory). Currently Write2 is only used when signatures are not required at the moment but after more testing we will enable that as well). Thanks to James Slepicka and Sam Flory for initial investigation.

2006-02-14[CIFS] SessionSetup cleanup part 2Steve French1-0/+1
The cifs session setup code has three cases, and a fourth for backlevel LANMAN2 style session setup needed to be added. This new session setup implmentation will eventually replace the other three and should be easier to read while fixing a few minor problems (not setting the LARGE READ/WRITEX flags when NTLMSSP was negotiated for example) and adding support for NTLMv2 (which will be added with the next patch. In the meantime, this code is marked in an CONFIG_CIFS_EXPERIMENTAL block and will not be turned on by default until it is tested against more server types.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
