From 1b58d90008bcb4d0f58524867957af5e12ac1f2f Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Thu, 7 Jul 2011 14:59:41 -0700 Subject: [PATCH] Fix bug #8293 - SMB2 doesn't rotate the log files often enough. 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. --- source3/smbd/globals.h | 3 ++- source3/smbd/process.c | 4 ++-- source3/smbd/smb2_server.c | 17 +++++++++++++++++ 3 files changed, 21 insertions(+), 3 deletions(-) diff --git a/source3/smbd/globals.h b/source3/smbd/globals.h index 51ea367..a98936a 100644 --- a/source3/smbd/globals.h +++ b/source3/smbd/globals.h @@ -483,6 +483,8 @@ struct smbd_server_connection { int dirhandles_open; } searches; + uint64_t num_requests; + struct { struct fd_event *fde; @@ -510,7 +512,6 @@ struct smbd_server_connection { int ref_count; } echo_handler; - uint64_t num_requests; struct { bool encrypted_passwords; bool spnego; diff --git a/source3/smbd/process.c b/source3/smbd/process.c index ca52626..339d005 100644 --- a/source3/smbd/process.c +++ b/source3/smbd/process.c @@ -1621,7 +1621,7 @@ static void process_smb(struct smbd_server_connection *sconn, sconn->trans_num++; done: - sconn->smb1.num_requests++; + sconn->num_requests++; /* The timeout_processing function isn't run nearly often enough to implement 'max log size' without @@ -1630,7 +1630,7 @@ done: level 10.
