From b45259d419d682ec26351eda34395e306bd05253 Mon Sep 17 00:00:00 2001 From: Namjae Jeon Date: Fri, 19 Apr 2024 23:46:34 +0900 Subject: [PATCH] ksmbd: common: use struct_group_attr instead of struct_group for network_open_info commit 0268a7cc7fdc47d90b6c18859de7718d5059f6f1 upstream. 4byte padding cause the connection issue with the applications of MacOS. smb2_close response size increases by 4 bytes by padding, And the smb client of MacOS check it and stop the connection. This patch use struct_group_attr instead of struct_group for network_open_info to use __packed to avoid padding.
