[ Upstream commit414849040f] Coverity Scan report the following one. This report is a false alarm. Because fp is never NULL when rc is zero. This patch add null check for fp in ksmbd_update_fstate to make alarm silence. *** CID 1568583: Null pointer dereferences (FORWARD_NULL) /fs/smb/server/smb2pdu.c: 3408 in smb2_open() 3402 path_put(&path); 3403 path_put(&parent_path); 3404 } 3405 ksmbd_revert_fsids(work); 3406 err_out1: 3407 if (!rc) { >>> CID 1568583: Null pointer dereferences (FORWARD_NULL) >>> Passing null pointer "fp" to "ksmbd_update_fstate", which dereferences it. 3408 ksmbd_update_fstate(&work->sess->file_table, fp, FP_INITED); 3409 rc = ksmbd_iov_pin_rsp(work, (void *)rsp, iov_len); 3410 } 3411 if (rc) { 3412 if (rc == -EINVAL) 3413 rsp->hdr.Status = STATUS_INVALID_PARAMETER; Fixes:e2b76ab8b5("ksmbd: add support for read compound") Reported-by: Coverity Scan <scan-admin@coverity.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
