[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Anastasia Belova <abelova@xxxxxxxxxxxxx>

[ Upstream commit a51e5d293dd1c2e7bf6f7be788466cd9b5d280fb ]

If the returning value of SMB2_set_info_init is an error-value,
exit the function.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 0967e5457954 ("cifs: use a compound for setting an xattr")
