(bug #8357) Currently we skip, the "gone async" interim response on read and write, this caused the aio code path to grant 0 credits to the client in the read/write responses. metze Autobuild-User: Stefan Metzmacher <metze@samba.org> Autobuild-Date: Sun Aug 7 22:23:57 CEST 2011 on sn-devel-104

smb2_validate_message_id: bad message_id Modify the credit granting algorithm to closer to what I believe Windows does. Split up max_credits into 1/16ths, and then scale the requested credits by how many 16ths have been currently granted. Less than 1/16th == grant all requested (100%), scale down as more have been granted. Never ask for less than 1 if the client asked for at least 1.

2011-07-20s3-auth use auth_user_info not netr_SamInfo3 in auth3_session_infoAndrew Bartlett1-1/+1
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>

Move the num_requests field out of the smb1 struct into the generic struct smbd_server_connection struct. Use it to count SMB2 requests as well as SMB1 and ensure that check_log_size() is called every 50 SMB2 requests.

2011-07-07s3:smb2_server: call change_to_root_user() or smbd_smb2_request_check_tcon()Stefan Metzmacher1-3/+26
For all requests which don't operate on a tcon, we should call change_to_root_user(), to match the SMB1 behavior. For SMB1 we do the following operations without AS_USER: /* 0x70 */ { "SMBtcon",reply_tcon,0}, /* 0x71 */ { "SMBtdis",reply_tdis,DO_CHDIR}, /* 0x72 */ { "SMBnegprot",reply_negprot,0}, /* 0x73 */ { "SMBsesssetupX",reply_sesssetup_and_X,0}, /* 0x74 */ { "SMBulogoffX",reply_ulogoffX, 0}, /* ulogoff doesn't give a valid TID */ /* 0x75 */ { "SMBtconX",reply_tcon_and_X,0}, ... /* 0x2b */ { "SMBecho",reply_echo,0}, ... /* 0xa4 */ { "SMBntcancel",reply_ntcancel, 0 }, For SMB2tdis we still call smbd_smb2_request_check_tcon() as close_cnum() calls change_to_root_user() when needed. metze Signed-off-by: Jeremy Allison <jra@samba.org>

Pass in the correct vector to the signing algorithm in an async response - we must start with vector[1] which has the SMB2_HDR_BODY length, not vector[0] which is the 4 byte packet length. Also note we're passing in 2 vectors not 3. Metze please review. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Wed Jun 29 20:09:21 CEST 2011 on sn-devel-104

2010-12-20CREATE in a compound CREATE/NOTIFY sequence was being passed through ↵Ken Harris1-17/+17
set_operation_credits() twice (ultimately perhaps because of bug 7331 involving this compound sequence and the need to be ready for any incoming CANCEL of the NOTIFY). This had the server thinking it had granted more credit than it actually had, which lead to zero-credits being granted in interim NOTIFY responses.

2010-06-02Fix a crash bug found by Ira Cooper <samba@ira.wakeful.net>.Jeremy Allison1-4/+5
A create call comes in, goes async (on the oplock request). At a later time (just before a cancel request is received) it completes, and goes through smbd_smb2_request_reply() to send the reply to the create call. However, the output socket queue is full, so when tstream_writev_queue_send() is called from smbd_smb2_request_reply(), the smb2req stays on the "being processed" queue on sconn->smb2.requests, as only when tstream_writev_queue_send() completes is smbd_smb2_request_writev_done() get called, which will TALLOC_FREE the smb2req (and thus take if off the queue). The cancel comes in, gets processed and looks through the requests on the queue, and BANG - hits the smb2req that has already been processed and is outgoing.... Remove the request from the queue once tstream_writev_queue_send() is called and not in the talloc destructor function. Jeremy.

64-bit Vista client It turns out that the persistent handles are used by the Microsoft redirector to index files on oplock break requests. So even if we don't do durable handles (yet) we must set the persistent handle on create. For now just use the same handle value as we use for volatile. Jeremy.
