net: loopback: use NET_NAME_PREDICTABLE for name_assign_type

2022-12-21T16:36:38+00:00

[ Upstream commit 31d929de5a112ee1b977a89c57de74710894bbbf ] When the name_assign_type attribute was introduced (commit 685343fc3ba6, "net: add name_assign_type netdev attribute"), the loopback device was explicitly mentioned as one which would make use of NET_NAME_PREDICTABLE: The name_assign_type attribute gives hints where the interface name of a given net-device comes from. These values are currently defined: ... NET_NAME_PREDICTABLE: The ifname has been assigned by the kernel in a predictable way that is guaranteed to avoid reuse and always be the same for a given device. Examples include statically created devices like the loopback device [...] Switch to that so that reading /sys/class/net/lo/name_assign_type produces something sensible instead of returning -EINVAL.

selftests: net: Use "grep -E" instead of "egrep"

[ Upstream commit 6a30d3e3491dc562384e9f15b201a8a25b57439f ] The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this using "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/net` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang Link: https://lore.kernel.org/r/1669864248-829-1-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Jakub Kicinski Signed-off-by: Sasha Levin

Bluetooth: L2CAP: Fix u8 overflow

2022-12-21T16:36:38+00:00

[ Upstream commit bcd70260ef56e0aee8a4fc6cd214a419900b0765 ] By keep sending L2CAP_CONF_REQ packets, chan->num_conf_rsp increases multiple times and eventually it will wrap around the maximum number (i.e., 255). This patch prevents this by adding a boundary check with L2CAP_MAX_CONF_RSP Btmon log: Bluetooth monitor ver 5.64 = Note: Linux version 6.1.0-rc2 (x86_64) 0.264594 = Note: Bluetooth subsystem version 2.22 0.264636 @ MGMT Open: btmon (privileged) version 1.22 {0x0001} 0.272191 = New Index: 00:00:00:00:00:00 (Primary,Virtual,hci0) [hci0] 13.877604 @ RAW Open: 9496 (privileged) version 2.22 {0x0002} 13.890741 = Open Index: 00:00:00:00:00:00 [hci0] 13.900426 (...) > ACL Data RX: Handle 200 flags 0x00 dlen 1033 #32 [hci0] 14.273106 invalid packet size (12 != 1033) 08 00 01 00 02 01 04 00 01 10 ff ff ............ > ACL Data RX: Handle 200 flags 0x00 dlen 1547 #33 [hci0] 14.273561 invalid packet size (14 != 1547) 0a 00 01 00 04 01 06 00 40 00 00 00 00 00 ........@..... > ACL Data RX: Handle 200 flags 0x00 dlen 2061 #34 [hci0] 14.274390 invalid packet size (16 != 2061) 0c 00 01 00 04 01 08 00 40 00 00 00 00 00 00 04 ........@....... > ACL Data RX: Handle 200 flags 0x00 dlen 2061 #35 [hci0] 14.274932 invalid packet size (16 != 2061) 0c 00 01 00 04 01 08 00 40 00 00 00 07 00 03 00 ........@....... = bluetoothd: Bluetooth daemon 5.43 14.401828 > ACL Data RX: Handle 200 flags 0x00 dlen 1033 #36 [hci0] 14.275753 invalid packet size (12 != 1033) 08 00 01 00 04 01 04 00 40 00 00 00 ........@...

HID: uclogic: Add HID_QUIRK_HIDINPUT_FORCE quirk

2022-12-21T16:36:38+00:00

[ Upstream commit 3405a4beaaa852f3ed2a5eb3b5149932d5c3779b ] Commit f7d8e387d9ae ("HID: uclogic: Switch to Digitizer usage for styluses") changed the usage used in UCLogic from "Pen" to "Digitizer". However, the IS_INPUT_APPLICATION() macro evaluates to false for HID_DG_DIGITIZER causing issues with the XP-Pen Star G640 tablet. Add the HID_QUIRK_HIDINPUT_FORCE quirk to bypass the IS_INPUT_APPLICATION() check.

usb: dwc3: pci: Update PCIe device ID for USB3 controller on CPU sub-system for Raptor Lake

commit f05f80f217bf52443a2582bca19fd78188333f25 upstream. The device ID 0xa70e is defined for the USB3 device controller in the CPU sub-system of Raptor Lake platform.

igb: Initialize mailbox message for VF reset

2022-12-21T16:36:37+00:00

commit de5dc44370fbd6b46bd7f1a1e00369be54a041c8 upstream. When a MAC address is not assigned to the VF, that portion of the message sent to the VF is not set. The memory, however, is allocated from the stack meaning that information may be leaked to the VM. Initialize the message buffer to 0 so that no information is passed to the VM in this case.

xhci: Apply XHCI_RESET_TO_DEFAULT quirk to ADL-N

2022-12-21T16:36:37+00:00

commit fed70b61ef2c0aed54456db3d485b215f6cc3209 upstream. ADL-N systems have the same issue as ADL-P, where a large boot firmware delay is seen if USB ports are left in U3 at shutdown. So apply the XHCI_RESET_TO_DEFAULT quirk to ADL-N as well. This patch depends on commit 34cd2db408d5 ("xhci: Add quirk to reset host back to default state at shutdown"). The issue it fixes is a ~20s boot time delay when booting from S5. It affects ADL-N devices, and ADL-N support was added starting from v5.16.
