* s3:smb2_server: avoid calling set_current_user_info() for each requestStefan Metzmacher2013-11-271-1/+1

* s3:smb2_server: generate a header blob for the sendfile pathStefan Metzmacher2013-11-271-0/+1
| | | | | | | | | | We need to pass the NBT header, SMB2 header and SMB2 Read header as header blob to SMB_VFS_SENDFILE(). This allows the usage of MSG_SEND or other tricks to avoid multiple TCP packets on the wire. Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: David Disseldorp <ddiss@samba.org>
* s3:smb2_server: for performance reasons we use tevent_fd and readv/writev ↵Stefan Metzmacher2013-11-271-3/+25
| | | | | | | | | | | | | | | | | | | | | directly Going via tevent_req_create/talloc_free at multiple layer costs too much cpu cycles per request. I tested downloading a 16GB (sparse) file with smbclient -b1 -mNT1, and -mSMB2_02. Using smb2 max read = 64512, which means smb1 and smb2 will use the same read size. I build with -O3 -g and compared the results with valgrind --tool=callgrind. With -mNT1 the server uses about 2.000.000.000 cpu cycles. This patch reduces the userspace cpu cycles for -mSMB2_02 from about ~ 8.000.000.000 down to ~ 4.000.000.000.

* smbd:smb2: successfully answer a DHnC request when the initial create was DH2QMichael Adam2013-10-051-1/+1
| | | | | | | | | | | | I.e. the durable reconnect attempt is v1 while the original create was durable v2 including the create guid. Implement this by skipping the create_guid verification when the reconnect request is v1.

* Sigh :-(. Removing optimization prematurely is the root of all evil :-(.Jeremy Allison2012-09-131-0/+1
| | | | | | | | | | | | | | | | | Sorry for the mistake, but the LastDir singleton cache in vfs_ChDir() actually plays an important role. When we're processing a stream of SMB1/SMB2/SMB3 requests we don't want to add a chdir()/getcwd() system call pair on every request if they're all on the same connection and dealing with the same base path. I did some testing with a program that times 1,000,000 chdir() requests vs. 1,000,000 strcmp requests and it's a penalty of 10x doing the system calls. Just because it's old code, doesn't mean it's bad :-(. Autobuild-User(master): Jeremy Allison <jra@samba.org> Autobuild-Date(master): Thu Sep 13 21:31:42 CEST 2012 on sn-devel-104
