commit 10a2f0b3 upstream. The setkey function for GCM/CCM algorithms didn't verify the key length before copying the key and subtracting the salt length. This patch delays the copying of the key til after the verification has been done. It also adds checks on the key length to ensure that it's at least as long as the salt.

commit 6cf87e5e upstream. There exist many FT2232-based JTAG+UART adapter designs in which FT2232 Channel A is used for JTAG and Channel B is used for UART. The best way to handle them in Linux is to have the ftdi_sio driver create a ttyUSB device only for Channel B and not for Channel A: a ttyUSB device for Channel A would be bogus and will disappear as soon as the user runs OpenOCD or other applications that access Channel A for JTAG from userspace, causing undesirable noise for users. The ftdi_sio driver already has a dedicated quirk for such JTAG+UART FT2232 adapters, and it requires assigning custom USB IDs to such adapters and adding these IDs to the driver with the ftdi_jtag_quirk applied. Boutique hardware manufacturer Falconia Partners LLC has created a couple of JTAG+UART adapter designs (one buffered, one unbuffered) as part of FreeCalypso project, and this hardware is specifically made to be used with Linux hosts, with the intent that Channel A will be accessed only from userspace via appropriate applications, and that Channel B will be supported by the ftdi_sio kernel driver, presenting a standard ttyUSB device to userspace. Toward this end the hardware manufacturer will be programming FT2232 EEPROMs with custom USB IDs, specifically with the intent that these IDs will be recognized by the ftdi_sio driver with the ftdi_jtag_quirk applied.

commit 339ddaa6 upstream. Starting with the upgrade to v5.8-rc3, I've noticed I wasn't able to connect to my Bluetooth headset properly anymore. While connecting to the device would eventually succeed, bluetoothd seemed to be confused about the current connection state where the state was flapping hence and forth. Bisecting this issue led to commit 3ca44c16 (Bluetooth: Consolidate encryption handling in hci_encrypt_cfm, 2020-05-19), which refactored `hci_encrypt_cfm` to also handle updating the connection state. The commit in question changed the code to call `hci_connect_cfm` inside `hci_encrypt_cfm` and to change the connection state. But with the conversion, we now only update the connection state if a status was set already. In fact, the reverse should be true: the status should be updated if no status is yet set. So let's fix the isuse by reversing the condition. Fixes: 3ca44c16 ("Bluetooth: Consolidate encryption handling in hci_encrypt_cfm") Signed-off-by:

commit a2ec905d upstream. Fix kernel oops observed when an ext adv data is larger than 31 bytes. This can be reproduced by setting up an advertiser with advertisement larger than 31 bytes. The issue is not sensitive to the advertisement content. In particular, this was reproduced with an advertisement of 229 bytes filled with 'A'. See stack trace below. This is fixed by not catching ext_adv as legacy adv are only cached to be able to concatenate a scanable adv with its scan response before sending it up through mgmt. With ext_adv, this is no longer necessary. general protection fault: 0000 [#1] SMP PTI CPU: 6 PID: 205 Comm: kworker/u17:0 Not tainted 5.4.0-37-generic #41-Ubuntu Hardware name: Dell Inc.

commit f45a4248 upstream. When get_registers() fails in set_ethernet_addr(),the uninitialized value of node_id gets copied over as the address. So, check the return value of get_registers(). If get_registers() executed successfully (i.e., it returns sizeof(node_id)), copy over the MAC address using ether_addr_copy() (instead of using memcpy()). Else, if get_registers() failed instead, a randomly generated MAC address is set as the MAC address instead. Reported-by:

[ Upstream commit f32f1933 ] syzbot managed to crash a host by creating a bond with a GRE device. For non Ethernet device, bonding calls bond_setup_by_slave() instead of ether_setup(), and unfortunately dev->needed_headroom was not copied from the new added member.

[ Upstream commit e94ee171 ] The struct flowi must never be interpreted by itself as its size depends on the address family. Therefore it must always be grouped with its original family value. In this particular instance, the original family value is lost in the function xfrm_state_find. Therefore we get a bogus read when it's coupled with the wrong family which would occur with inter- family xfrm states. This patch fixes it by keeping the original family value. Note that the same bug could potentially occur in LSM through the xfrm_state_pol_flow_match hook. I checked the current code there and it seems to be safe for now as only secid is used which is part of struct flowi_common. But that API should be changed so that so that we don't get new bugs in the future. We could do that by replacing fl with just secid or adding a family field. Reported-by:

[ Upstream commit afdd1ebb ] When FUJITSU_LAPTOP is enabled and NEW_LEDS is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for LEDS_CLASS Depends on [n]: NEW_LEDS [=n] Selected by [y]: - FUJITSU_LAPTOP [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && ACPI [=y] && INPUT [=y] && BACKLIGHT_CLASS_DEVICE [=y] && (ACPI_VIDEO [=n] || ACPI_VIDEO [=n]=n) The reason is that FUJITSU_LAPTOP selects LEDS_CLASS without depending on or selecting NEW_LEDS while LEDS_CLASS is subordinate to NEW_LEDS.

[ Upstream commit 7241c5a6 ] EEE should be only be enabled during stmmac_mac_link_up() when the link are up and being set up properly. set_eee should only do settings configuration and disabling the eee. Without this fix, turning on EEE using ethtool will return "Operation not supported". This is due to the driver is in a dead loop waiting for eee to be advertised in the for eee to be activated but the driver will only configure the EEE advertisement after the eee is activated. Ethtool should only return "Operation not supported" if there is no EEE capbility in the MAC controller. Fixes: 8a7493e5 ("net: stmmac: Fix a race in EEE enable callback") Signed-off-by:

commit 8aa7b526 upstream. With multiple DNAT rules it's possible that after destination translation the resulting tuples collide. For example, two openvswitch flows: nw_dst=10.0.0.10,tp_dst=10, actions=ct(commit,table=2,nat(dst=20.0.0.1:20)) nw_dst=10.0.0.20,tp_dst=10, actions=ct(commit,table=2,nat(dst=20.0.0.1:20)) Assuming two TCP clients initiating the following connections: 10.0.0.10:5000->10.0.0.10:10 10.0.0.10:5000->10.0.0.20:10 Both tuples would translate to 10.0.0.10:5000->20.0.0.1:20 causing nf_conntrack_confirm() to fail because of tuple collision. Netfilter handles this case by allocating a null binding for SNAT at egress by default. Perform the same operation in openvswitch for DNAT if no explicit SNAT is requested by the user and allocate a null binding for SNAT for packets in the "original" direction.

commit 9a9e7749 upstream. The variable "i" isn't initialized back correctly after the first loop under the label inst_rollback gets executed. The value of "i" is assigned to be option_count - 1, and the ensuing loop (under alloc_rollback) begins by initializing i--. Thus, the value of i when the loop begins execution will now become i = option_count - 2. Thus, when kfree(dst_opts[i]) is called in the second loop in this order, (i.e., inst_rollback followed by alloc_rollback), dst_optsp[option_count - 2] is the first element freed, and dst_opts[option_count - 1] does not get freed, and thus, a memory leak is caused. This memory leak can be fixed, by assigning i = option_count (instead of option_count - 1). Fixes: 80f7c668 ("team: add support for per-port options") Reported-by:
