Add DM_SECURE_DATA_FLAG which userspace can use to ensure that all buffers allocated for dm-ioctl are wiped immediately after use. The user buffer is wiped as well (we do not want to keep and return sensitive data back to userspace if the flag is set). Wiping is useful for cryptsetup to ensure that the key is present in memory only in defined places and only for the time needed. (For crypt, key can be present in table during load or table status, wait and message commands). Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com> |
