2011-02-10s3-auth Rename cryptic 'ptok' to security_tokenAndrew Bartlett1-9/+9
This will allow the auth_serversupplied_info struct to be migrated to auth_session_info easier. Adnrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>

lookups go through Get_Pwnam_alloc(), which is the correct wrapper function. We were using it *some* of the time anyway, so this just makes us properly consistent. Jeremy. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Wed Oct 20 16:02:12 UTC 2010 on sn-devel-104

This will reduce the noise from merges of the rest of the libcli/security code, without this commit changing what code is actually used.

2010-09-26s3: Remove talloc_autofree_context() from change_to_guest()Volker Lendecke1-1/+1
pass is freed at the exit of this routine
2010-09-11s3:auth Remove NT_USER_TOKENAndrew Bartlett1-1/+1
The all UPPER case typedef is no longer the preferred Samba style and this makes it easier to see that this is the IDL-derivied structure Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2010-08-31s3-auth Rename NT_USER_TOKEN user_sids -> sidsAndrew Bartlett1-2/+2
This is closer to the struct security_token from security.idl

This reduces precompiled headers by another 4 MB and also slightly speeds up the build. Guenther

conn token is uid 0. This simplifies change_to_user() and removes special processing of the assignments we pass to set_sec_ctx(). Jeremy.
2010-03-15Add accessor functions for current uid, gid, unix token, NT token and vuid.Jeremy Allison1-0/+43

2010-03-12Remove more uses of "extern struct current_user current_user;".Jeremy Allison1-16/+58
Use accessor functions to get to this value. Tidies up much of the user context code. Volker, please look at the changes in smbd/uid.c to familiarize yourself with these changes as I think they make the logic in there cleaner. Cause smbd/posix_acls.c code to look at current user context, not stored context on the conn struct - allows correct use of these function calls under a become_root()/unbecome_root() pair. Jeremy.

2009-05-04Fix bug #6315 smbd crashes doing vfs_full_audit on IPC$ close event.Jeremy Allison1-3/+44
The underlying problem is that once SMBulogoff is called, all server_info contexts associated with the vuid should become invalid, even if that's the context being currently used by the connection struct (tid). When the SMBtdis comes in it doesn't need a valid vuid value, but the code called inside vfs_full_audit always assumes that there is one (and hence a valid conn->server_info pointer) available. This is actually a bug inside the vfs_full_audit and other code inside Samba, which should only indirect conn->server_info on calls which require AS_USER to be set in our process table. I could fix all these issues, but there's no guarentee that someone might not add more code that fails this assumption, as it's a hard assumption to break (it's usually true). So what I've done is to ensure that on SMBulogoff the previously used conn->server_info struct is kept around to be used for print debugging purposes (it won't be used to change to an invalid user context, as such calls need AS_USER set). This isn't strictly correct, as there's no association with the (now invalid) context being freed and the call that causes conn->server_info to be indirected, but it's good enough for most cases. The hard part was to ensure that once a valid context is used again (via new sessionsetupX calls, or new calls on a still valid vuid on this tid) that we don't leak memory by simply replacing the stored conn->server_info pointer. We would never actually leak the memory (as all conn->server_info pointers are talloc children of conn), but with the previous patch a malicious client could cause many server_info structs to be talloced by the right combination of SMB calls. This new patch introduces free_conn_server_info_if_unused(), which protects against the above. Jeremy.
2009-04-16Fix bug found by Tim Prouty, logging off and then re-using a vuid can cause ↵Jeremy Allison1-0/+11
smbd to access a freed structure. Jeremy.
2009-03-03Fix bug #6155 - "force group" is no longer working as expected.Jeremy Allison1-3/+8
We need to store the "force group" uid separately from the conn->server_info token as we need to apply it separately also. Volker PLEASE CHECK ! Jeremy.
2009-01-08s3:smbd: move all globals and static variables in globals.[ch]Stefan Metzmacher1-10/+1
The goal is to move all this variables into a big context structure. metze
2009-01-08s3:smbd: remove pointless static variable in uid.cStefan Metzmacher1-7/+4
We always free the value at the end of the function, so we don't need a static variable to hold just NULL for the time the function isn't executed. metze
2008-12-04Fix bug #1254 - write list not working under share-level securityJeremy Allison1-35/+46
A somewhat more elegant fix than I could use for 3.2.x or 3.0.x. Turns out the only part of check_user_ok() that needs to change for share level security is the VUID cache pieces, so I can just always use check_user_ok() for all lp_security() cases. Jeremy

2008-11-06Make us clean under valgrind --leak-check=full by using ↵Jeremy Allison1-1/+1
talloc_autofree_context() instead of NULL. Remove the code in memcache that does a TALLOC_FREE on stored pointers. That's a disaster waiting to happen. If you're storing talloc'ed pointers, you can't know their lifecycle and they should be deleted when their parent context is deleted, so freeing them at some arbitrary point later will be a double-free. Jeremy.

Most already used it, these two still used SNUM(conn), where the only caller of this routine (change_to_user) had set snum = SNUM(conn). (This used to be commit b14e59bfdbfb62494002e22d0665c4d420484245)
