Replace the deprecated one-element arrays with flexible-array members in the structs filesystem_attribute_info and filesystem_device_info.
There are no binary differences after this conversion. Link: https://github.com/KSPP/linux/issues/79 Signed-off-by: Thorsten Blum <[email protected]> --- Changes in v2: - Take struct size changes into account and do not subtract 2 additional bytes after feedback from Gustavo A. R. Silva - Compare the binaries before and after the conversion and add a note that there are no differences - Link to v1: https://lore.kernel.org/linux-kernel/[email protected]/ --- fs/smb/server/smb2pdu.c | 4 ++-- fs/smb/server/smb_common.h | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/fs/smb/server/smb2pdu.c b/fs/smb/server/smb2pdu.c index 2df1354288e6..1ce747b4636b 100644 --- a/fs/smb/server/smb2pdu.c +++ b/fs/smb/server/smb2pdu.c @@ -5357,7 +5357,7 @@ static int smb2_get_info_filesystem(struct ksmbd_work *work, "NTFS", PATH_MAX, conn->local_nls, 0); len = len * 2; info->FileSystemNameLen = cpu_to_le32(len); - sz = sizeof(struct filesystem_attribute_info) - 2 + len; + sz = sizeof(struct filesystem_attribute_info) + len; rsp->OutputBufferLength = cpu_to_le32(sz); break; } @@ -5383,7 +5383,7 @@ static int smb2_get_info_filesystem(struct ksmbd_work *work, len = len * 2; info->VolumeLabelSize = cpu_to_le32(len); info->Reserved = 0; - sz = sizeof(struct filesystem_vol_info) - 2 + len; + sz = sizeof(struct filesystem_vol_info) + len; rsp->OutputBufferLength = cpu_to_le32(sz); break; } diff --git a/fs/smb/server/smb_common.h b/fs/smb/server/smb_common.h index 4a3148b0167f..cc1d6dfe29d5 100644 --- a/fs/smb/server/smb_common.h +++ b/fs/smb/server/smb_common.h @@ -213,7 +213,7 @@ struct filesystem_attribute_info { __le32 Attributes; __le32 MaxPathNameComponentLength; __le32 FileSystemNameLen; - __le16 FileSystemName[1]; /* do not have to save this - get subset? */ + __le16 FileSystemName[]; /* do not have to save this - get subset? */ } __packed; struct filesystem_device_info { @@ -226,7 +226,7 @@ struct filesystem_vol_info { __le32 SerialNumber; __le32 VolumeLabelSize; __le16 Reserved; - __le16 VolumeLabel[1]; + __le16 VolumeLabel[]; } __packed; struct filesystem_info { -- 2.46.0
