2012-10-29Fix bug #9329 - Directory listing with SeBackup can crash smbd.Jeremy Allison1-1/+11
When we do a become_root()/unbecome_root() pair to temporarily raise privilege, this NULLs out the NT token. If we're within a become_root()/unbecome_root() pair then return the previous token on the stack as our NT token. This is what we should be using to check against NT ACLs in the file server. This copes with security context changing when removing a file on close under the context of another user (when 2 users have a file open, one sets delete on close and then the other user has to actually do the delete).

2012-03-04s3-auth: Remove security=share (depricated since 3.6).Andrew Bartlett1-18/+5
This patch removes security=share, which Samba implemented by matching the per-share password provided by the client in the Tree Connect with a selection of usernames supplied by the client, the smb.conf or guessed from the environment. The rationale for the removal is that for the bulk of security=share users, we just we need a very simple way to run a 'trust the network' Samba server, where users mark shares as guest ok. This is still supported, and the smb.conf options are documented at https://wiki.samba.org/index.php/Public_Samba_Server At the same time, this closes the door on one of the most arcane areas of Samba authentication. Naturally, full user-name/password authentication remain available in security=user and above. This includes documentation updates for username and only user, which now only do a small amount of what they used to do.

2011-07-20s3-auth Use the common auth_session_infoAndrew Bartlett1-6/+6
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 Bartlett1-3/+3
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 Use struct auth_user_info_unix for unix_name and sanitized_usernameAndrew Bartlett1-6/+6

2011-07-20s3-auth Use *unix_token rather than utok in struct auth3_session_infoAndrew Bartlett1-15/+15
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 Bartlett1-7/+7
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.

2011-06-21s3-build: Provide a run-time shim to work around duplicate symbolsAndrew Bartlett1-3/+3
The become_root() and similar 'smbd' functions that are used widely in Samba libraries had 'dummy' copies in dummysmbd.c and dummyroot.c. These have been replaced by a runtime plugin mechanim, which ensures that standlone binaries still do nothing, while in smbd the correct function is used. This avoids having these as duplicate symbols in the smbd binary, which can cause unpredictable behaviour. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-05-31s3-smbd Split conn.c into 3 filesAndrew Bartlett1-44/+0

2011-02-22s3-auth Rename auth_serversupplied_info varaiables: server_info -> session_infoAndrew Bartlett1-60/+60
These variables, of type struct auth_serversupplied_info were poorly named when added into 2001, and in good consistant practice, this has extended all over the codebase in the years since. The structure is also not ideal for it's current purpose. Originally intended to convey the results of the authentication modules, it really describes all the essential attributes of a session. This rename will reduce the volume of a future patch to replaced these with a struct auth_session_info, with auth_serversupplied_info confined to the lower levels of the auth subsystem, and then eliminated. (The new structure will be the output of create_local_token(), and the change in struct definition will ensure that this is always run, populating local groups and privileges).
