Subject: [PATCH AUTOSEL 4.19 22/25] SMB3: incorrect file id in requests compounded with open
Date: Mon, 24 May 2021 10:50:05 -0400 [thread overview]
Message-ID: <20210524145008.2499049-22-sashal@kernel.org> (raw)
In-Reply-To: <20210524145008.2499049-1-sashal@kernel.org>
From: Steve French <stfrench@microsoft.com>
[ Upstream commit c0d46717b95735b0eacfddbcca9df37a49de9c7a ]
See MS-SMB2 3.2.4.1.4, file ids in compounded requests should be set to
0xFFFFFFFFFFFFFFFF (we were treating it as u32 not u64 and setting
it incorrectly).
