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
2010-08-06s3-netlogon: remove global include of netlogon.h.Günther Deschner1-0/+1
This reduces precompiled headers by another 4 MB and also slightly speeds up the build. Guenther

2010-03-15Remove the bool admin_user from conn struct. We no longer look at this to ↵Jeremy Allison1-5/+5

2010-03-15Simplify processing of "admin user". If a user is an admin_user ensure their ↵Jeremy Allison1-15/+14
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
Jeremy.
2010-03-15Rever e80ceb1d7355c8c46a2ed90d5721cf367640f4e8 "Remove more uses of "extern ↵Jeremy Allison1-57/+15
struct current_user current_user;"." As requested by Volker, split this into smaller commits. Jeremy.
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

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.
2008-06-19Wrap the unix token info in a unix_user_token in auth_serversupplied_infoVolker Lendecke1-13/+14
No functional change, this is a preparation for more current_user ref removal (This used to be commit dcaedf345e62ab74ea87f0a3fa1e3199c75c5445)

2008-06-14Consistently use snum in check_user_okVolker Lendecke1-2/+2
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)

2007-10-10r22978: Don't use current_user to prep the security ctx in change_to_userGerald Carter1-7/+15
since any SID/uid/gid translation calls will reset the struct when popping the security ctx. This should fix the standalone server configuration issues reported by David Rankin (thanks for the logs). (This used to be commit 63cb25bad19d9600399a6ee2221497d71e805320)
2007-10-10r17295: Back out the become_root_uid_only change on the POSIXJeremy Allison1-1/+0
acls code. I'm pretty sure this was safe, but become_root() does other things to the token stack that become_root_uid_only() does not, and as we're going into a vfs redirectred function I decided it wasn't safe for now. Jeremy. (This used to be commit b3e0f45488595aa96c852dab8e1349631a85dded)
