[PATCH openEuler-1.0-LTS 1/3] net: usb: ax88179_178a: fix packet alignment padding
by Yongqiang Liu 01 Sep '22

01 Sep '22

From: Jeremy Kerr <jk(a)ozlabs.org> stable inclusion from stable-v4.19.131 commit c191f7cf369c0090fdbeff0b6782d5eaa3a179d2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5NYS6 CVE: CVE-2022-2964 --------------------------- [ Upstream commit e869e7a17798d85829fa7d4f9bbe1eebd4b2d3f6 ] Using a AX88179 device (0b95:1790), I see two bytes of appended data on every RX packet. For example, this 48-byte ping, using 0xff as a payload byte: 04:20:22.528472 IP 192.168.1.1 > 192.168.1.2: ICMP echo request, id 2447, seq 1, length 64 0x0000: 000a cd35 ea50 000a cd35 ea4f 0800 4500 0x0010: 0054 c116 4000 4001 f63e c0a8 0101 c0a8 0x0020: 0102 0800 b633 098f 0001 87ea cd5e 0000 0x0030: 0000 dcf2 0600 0000 0000 ffff ffff ffff 0x0040: ffff ffff ffff ffff ffff ffff ffff ffff 0x0050: ffff ffff ffff ffff ffff ffff ffff ffff 0x0060: ffff 961f Those last two bytes - 96 1f - aren't part of the original packet. In the ax88179 RX path, the usbnet rx_fixup function trims a 2-byte 'alignment pseudo header' from the start of the packet, and sets the length from a per-packet field populated by hardware. It looks like that length field *includes* the 2-byte header; the current driver assumes that it's excluded. This change trims the 2-byte alignment header after we've set the packet length, so the resulting packet length is correct. While we're moving the comment around, this also fixes the spelling of 'pseudo'. Signed-off-by: Jeremy Kerr <jk(a)ozlabs.org> Signed-off-by: David S.
