2011-07-23Fix bug 8314] - smbd crash with unknown user.Jeremy Allison1-4/+11
All other auth modules code with being called with auth_method->private_data being NULL, make the auth_server module cope with this too. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Sat Jul 23 02:55:01 CEST 2011 on sn-devel-104

2011-07-20s3-auth Remove pointless destructor in make_server_infoAndrew Bartlett1-10/+0
All the callers allocate ->info3 as a talloc child already. As regardes the TALLOC_ZERO(), I added this originally out of parinoia many years ago. We do not consistantly zero session keys in memory, and for NTLMv2 and Kerberos they are random for each sesssion, so breaking into smbd far enough to read an old session key isn't a particularly interesting attack, compared with (say) reading the keytab or the password database. (NTLM and LM session keys are fixed derivitives of the passwords however). Andrew Bartlett
2011-07-20s3-auth inline make_auth_session_info into only callerAndrew Bartlett3-25/+1
2011-07-20s3-auth Remove seperate guest booleanAndrew Bartlett1-3/+2
Instead, we base our guest calculations on the presence or absense of the authenticated users group in the token, ensuring that we have only one canonical source of this important piece of authorization data Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20auth: Set NETLOGON_GUEST and use it to determine guest statusAndrew Bartlett1-0/+3
These additional measures should help ensure we do not accidentily upgrade a guest to an authenticated user in the future. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20auth: Split out make_user_info_SamBaseInfo and add authenticated argumentAndrew Bartlett1-13/+5
This will allow the source3 auth code to call this without needing to double-parse the SIDs Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20s3-auth Use the common auth_session_infoAndrew Bartlett5-40/+40
This patch finally has the same structure being used to describe the authorization data of a user across the whole codebase. This will allow of our session handling to be accomplished with common code. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20s3-auth use auth_user_info not netr_SamInfo3 in auth3_session_infoAndrew Bartlett1-7/+20
This makes auth3_session_info identical to auth_session_info The logic to convert the info3 to a struct auth_user_info is essentially moved up the stack from the named pipe proxy in source3/rpc_server to create_local_token(). Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20s3-auth reimplement copy_session_info via NDR pull/pushAndrew Bartlett1-57/+23

2011-07-20s3-auth Clarify inputs and ouptuts by using elements from server_infoAndrew Bartlett1-5/+5
This allows us not the put all of these elements into the auth3_session_info if they are only used as inputs to these functions. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>

2011-07-20s3-auth: Remove unused lm_session_key from auth3_session_infoAndrew Bartlett1-10/+5
The long term authorization state needs only the final, negotiated session key, and not the original LM key that may possibly have been an input. The special case of the guest account simply needs both values filled back in with the zeros to avoid changing behaviour in the cached server_info. Signed-off-by: Andrew Tridgell <tridge@samba.org>

2011-07-20s3-auth Use struct auth_user_info_unix for unix_name and sanitized_usernameAndrew Bartlett1-18/+34
This is closer to the layout of struct auth_session_info in auth.idl Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20s3-auth Use *unix_token rather than utok in struct auth3_session_infoAndrew Bartlett2-38/+56
This brings this structure one step closer to the struct auth_session_info. A few SMB_ASSERT calls are added in some key places to ensure that this pointer is initialised, to make tracing any bugs here easier in future. NOTE: Many of the users of this structure should be reviewed, as unix and NT access checks are mixed in a way that should just be done using the NT ACL. This patch has not changed this behaviour however. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20s3-auth Use struct auth3_session_info outside the auth subsystemAndrew Bartlett4-24/+33
This seperation between the structure used inside the auth modules and in the wider codebase allows for a gradual migration from struct auth_serversupplied_info -> struct auth_session_info (from auth.idl) The idea here is that we keep a clear seperation between the structure before and after the local groups, local user lookup and the session key modifications have been processed, as the lack of this seperation has caused issues in the past. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20s3-auth Add struct auth3_session_info to aid transition to auth_session infoAndrew Bartlett3-0/+217
This will allow a gradual conversion of the required elements from the current struct auth_serversupplied_info. This commit adds the structure definition and some helper functions to copy between the two structures. At this stage these structures and functions are IDENTICAL to the existing code, and so show the past history of that code. The plan is to slowly modify them over the course of the patch series, so that the changes being made a clear. By using a seperate structure to auth_serversupplied_info we can remove elements that are not needed after the authentication, and we can choose a layout that best reflects the needs of runtime users, rather than the internals of the authentication subsystem. By eventually using the auth_session_info from auth.idl, we will gain a single session authorization structure across the whole codebase, allowing more code to be shared, and a much more transparent process for forwarding authorization credentials over the named pipe proxy.

2011-07-20s3-auth Restore nss_token behaviour by reading from server_infoAndrew Bartlett1-1/+1
The implementation of copy_serverinfo(), used to copy server_info into session_info never copied the nss_token variable, and so 17d8f0ad30847bb940f645ee1817d782ddaaee74 introduced this regression. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
