commit 5a33e906f651ea84ec909fd6453e13a9489bd391
Author: Volker Lendecke <vl at samba.org>
Date: Fri Nov 7 21:02:11 2008 +0100
Make "construct_reply_common" static
commit 8315677ca3ca9eed62fe6e24bac333b9b5dc763b
Author: Volker Lendecke <vl at samba.org>
Date: Fri Nov 7 20:38:05 2008 +0100
Do not write into inbuf for the transs request
Instead, fix up the outbuf in send_xx_reply. In those routines, we know
what we are returning.
commit 7a35506bb87fd784a4a7a5b81c2d2ab5c32b233b
Author: Volker Lendecke <vl at samba.org>
Date: Fri Nov 7 12:29:24 2008 +0100
Remove direct inbuf refs from send_trans_reply
commit 8637dd12325369e0056d77924cac577a67f2a0ab
Author: Volker Lendecke <vl at samba.org>
Date: Thu Nov 6 20:16:04 2008 +0100
change CHECK_READ to use smb_request instead of inbuf
commit 807ad174b288e4c3d36ed02e5ef02cd7a848ce0e
Author: Volker Lendecke <vl at samba.org>
Date: Thu Nov 6 12:14:08 2008 +0100
Remove a direct inbuf reference from reply_nttrans()
commit 52958ea115ab3d1d8cebaad47b5ffff7fc86a4cd
Author: Volker Lendecke <vl at samba.org>
Date: Wed Nov 5 19:19:17 2008 +0100
Remove a direct inbuf reference (should have been removed with 8987641d...)
commit 5e2956557b06b5b55dc8810b51bdbcf3e7f03c98
Author: Volker Lendecke <vl at samba.org>
Date: Wed Nov 5 19:16:06 2008 +0100
Remove the change to the user context in process_blocking_lock_queue()
commit 87d4138d095bd6554ded80a94fb706bb754ae4c6
Author: Volker Lendecke <vl at samba.org>
Date: Tue Nov 4 22:04:58 2008 +0100
