Shyam Prasad N a4f751c41a cifs: Return the error from crypt_message when enc/dec key not found. commit `0bd294b55a` upstream. In crypt_message, when smb2_get_enc_key returns error, we need to return the error back to the caller. If not, we end up processing the message further, causing a kernel oops due to unwarranted access of memory. Call Trace: smb3_receive_transform+0x120/0x870 [cifs] cifs_demultiplex_thread+0xb53/0xc20 [cifs] ? cifs_handle_standard+0x190/0x190 [cifs] kthread+0x116/0x130 ? kthread_park+0x80/0x80 ret_from_fork+0x1f/0x30 Signed-off-by: Shyam Prasad N <sprasad@microsoft.com> Reviewed-by: Pavel Shilovsky <pshilov@microsoft.com> Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com> CC: Stable <stable@vger.kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2020-10-29 09:54:59 +01:00

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
