[PATCH AUTOSEL 5.15 07/20] ksmbd: return STATUS_BAD_NETWORK_NAME error status if share is not configured

[Sasha Levin]

From: Namjae Jeon <linkinjeon@kernel.org>

[ Upstream commit fe54833dc8d97ef387e86f7c80537d51c503ca75 ]

If share is not configured in smb.conf, smb2 tree connect should return
STATUS_BAD_NETWORK_NAME instead of STATUS_BAD_NETWORK_PATH.

[PATCH AUTOSEL 5.15 10/20] ksmbd: don't remove dos attribute xattr on O_TRUNC open

[Sasha Levin]

From: Namjae Jeon <linkinjeon@kernel.org>

[ Upstream commit 17661ecf6a64eb11ae7f1108fe88686388b2acd5 ]

When smb client open file in ksmbd share with O_TRUNC, dos attribute
xattr is removed as well as data in file. This cause the FSCTL_SET_SPARSE
request from the client fails because ksmbd can't update the dos attribute
after setting ATTR_SPARSE_FILE. And this patch fix xfstests generic/469
test also.
