Subject: [PATCH 1/2] ksmbd: common: use struct_group_attr instead of struct_group for network_open_info
Date: Sat, 20 Apr 2024 09:43:47 +0900 [thread overview]
Message-ID: <20240420004348.4907-1-linkinjeon@kernel.org> (raw)
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.
