2021-09-18serial: 8250: Define RX trigger levels for OxSemi 950 devicesMaciej W. Rozycki1-0/+1
[ Upstream commit d7aff291d069c4418285f3c8ee27b0ff67ce5998 ] Oxford Semiconductor 950 serial port devices have a 128-byte FIFO and in the enhanced (650) mode, which we select in `autoconfig_has_efr' with the ECB bit set in the EFR register, they support the receive interrupt trigger level selectable with FCR bits 7:6 from the set of 16, 32, 112, 120. This applies to the original OX16C950 discrete UART[1] as well as 950 cores embedded into more complex devices. For these devices we set the default to 112, which sets an excessively high level of 112 or 7/8 of the FIFO capacity, unlike with other port types where we choose at most 1/2 of their respective FIFO capacities. Additionally we don't make the trigger level configurable. Consequently frequent input overruns happen with high bit rates where hardware flow control cannot be used (e.g. terminal applications) even with otherwise highly-performant systems. Lower the default receive interrupt trigger level to 32 then, and make it configurable. Document the trigger levels along with other port types, including the set of 16, 32, 64, 112 for the transmit interrupt as well[2].

2021-08-02aspeed-mctp: Add EID information related ioctlsKarol Wachowski1-0/+29
Implement two new ioctls for storing EID related information: * ASPEED_MCTP_IOCTL_GET_EID_INFO * ASPEED_MCTP_IOCTL_SET_EID_INFO Driver stores EID mapping in a list which is traversed when one tries to get information using ASPEED_MCTP_IOCTL_GET_EID_INFO ioctl, when given EID mapping is not found in the list, next entry is returned. When there are no entries with EIDs higher than specified in the IOCTL call -ENODEV is returned. Whenever new information about EID mapping is stored with ASPEED_MCTP_IOCTL_SET_EID_INFO ioctl driver empties exsiting list of mappings and creates new one based on user input. After insertion list is sorted by EID. Invalid input such as duplicated EIDs will cause driver to return -EINVAL. Signed-off-by: Karol Wachowski <karol.wachowski@intel.com>
2021-08-02soc: aspeed: mctp: Add API to register client for MCTP typeAndrzej Kacprowski1-0/+16
MCTP client can register for receiving packets with selected MCTP message type or PCIE vendor defined message type. Vendor defined type is 2 bytes but in Intel VDMs the first byte is variable and only the second byte contains constant message type - to support this use case we have to specify 2 byte mask that is applied to packet type before comparing with registered vendor type. When MCTP packet arrives its header is compared with a list of registered (vendor) types. If no client registered for packet's (vendor) type then the packet is dispatched to the default client. Fragmented packets are not considered for type matching. Only one client can register for given (vendor) type. Client can register for multiple (vendor) types. All packet fields must be specified in big endian byte order. This feature allows to support multiple clients simultaneously but only one client per (vendor) message type. For example we can have PECI client in kernel that uses PECI vendor message type, dcpmm daemon in user space that handles NVDIMM vendor type messages and mctpd service that handles MCTP control and PLDM message types. tested with peci_mctp_test application Signed-off-by: Andrzej Kacprowski <andrzej.kacprowski@linux.intel.com>
2021-08-02soc: aspeed: mctp: Add IOCTL to register default clientAndrzej Kacprowski1-0/+5
Add IOCTL to register given client as default client that receives all packets that were not dispatched to other clients. This IOCTL is intended to be used by mctpd service or test application that should receive all packets that are not claimed by other clients. mctpd service might not be the first user space client since dcpmm or telemetry client can start before mctpd or mctpd can crash and be restarted automatically at any time. To preserve backward compatibility with mctpd, the first user space client will be registered automatically as default client - once mctpd is modified to call ASPEED_MCTP_IOCTL_REGISTER_DEFAULT_HANDLER we can remove this workaround.

2021-08-02i2c: Add mux hold/unhold msg typesJae Hyun Yoo1-0/+1
This commit adds mux hold/unhold message types to support extended mux control for IPMB and MCTP devices. A hold or an unhold message can be added at the end of I2C message stream wrapped by repeated-start, also can be used as a single message independantly. This mux hold/unhold message will be delivered throughout all mux levels in the path. Means that if it goes to multi-level mux path, all muxes will be held/unheld by this message. 1. Hold message struct i2c_msg msg; uint16_t timeout = 5000; // timeout in ms. 5 secs in this example. msg.addr = 0x0; // any value can be used. addr will be ignored in this packet. msg.flags = I2C_M_HOLD; // set this flag to indicate it's a hold message. msg.len = sizeof(uint16_t); // timeout value will be delivered using two bytes buffer. msg.buf = (uint8_t *)&timeout; // set timeout value. 2. Unhold message struct i2c_msg msg; uint16_t timeout = 0; // set 0 for an unhold message. msg.addr = 0x0; // any value can be used. addr will be ignored in this packet. msg.flags = I2C_M_HOLD; // set this flag to indicate it's an unhold message. msg.len = sizeof(uint16_t); // timeout value will be delivered using two bytes buffer. msg.buf = (uint8_t *)&timeout; // set timeout value. This unhold message can be delivered to a mux adapter even when a bus is locked so that any holding state can be unheld immediately by invoking this unhold message.

2021-08-02peci: Add support for PECI bus driver coreJae Hyun Yoo1-0/+661
This commit adds driver implementation for PECI bus core into linux driver framework. PECI (Platform Environment Control Interface) is a one-wire bus interface that provides a communication channel from Intel processors and chipset components to external monitoring or control devices. PECI is designed to support the following sideband functions: * Processor and DRAM thermal management - Processor fan speed control is managed by comparing Digital Thermal Sensor (DTS) thermal readings acquired via PECI against the processor-specific fan speed control reference point, or TCONTROL. Both TCONTROL and DTS thermal readings are accessible via the processor PECI client. These variables are referenced to a common temperature, the TCC activation point, and are both defined as negative offsets from that reference. - PECI based access to the processor package configuration space provides a means for Baseboard Management Controllers (BMC) or other platform management devices to actively manage the processor and memory power and thermal features. * Platform Manageability - Platform manageability functions including thermal, power, and error monitoring. Note that platform 'power' management includes monitoring and control for both the processor and DRAM subsystem to assist with data center power limiting. - PECI allows read access to certain error registers in the processor MSR space and status monitoring registers in the PCI configuration space within the processor and downstream devices. - PECI permits writes to certain registers in the processor PCI configuration space. * Processor Interface Tuning and Diagnostics - Processor interface tuning and diagnostics capabilities (Intel Interconnect BIST). The processors Intel Interconnect Built In Self Test (Intel IBIST) allows for infield diagnostic capabilities in the Intel UPI and memory controller interfaces. PECI provides a port to execute these diagnostics via its PCI Configuration read and write capabilities. * Failure Analysis - Output the state of the processor after a failure for analysis via Crashdump. PECI uses a single wire for self-clocking and data transfer. The bus requires no additional control lines. The physical layer is a self-clocked one-wire bus that begins each bit with a driven, rising edge from an idle level near zero volts. The duration of the signal driven high depends on whether the bit value is a logic '0' or logic '1'. PECI also includes variable data transfer rate established with every message. In this way, it is highly flexible even though underlying logic is simple. The interface design was optimized for interfacing between an Intel processor and chipset components in both single processor and multiple processor environments. The single wire interface provides low board routing overhead for the multiple load connections in the congested routing area near the processor and chipset components. Bus speed, error checking, and low protocol overhead provides adequate link bandwidth and reliability to transfer critical device operating conditions and configuration information. This implementation provides the basic framework to add PECI extensions to the Linux bus and device models. A hardware specific 'Adapter' driver can be attached to the PECI bus to provide sideband functions described above. It is also possible to access all devices on an adapter from userspace through the /dev interface. A device specific 'Client' driver also can be attached to the PECI bus so each processor client's features can be supported by the 'Client' driver through an adapter connection in the bus.

2021-06-23icmp: don't send out ICMP messages with a source address of 0.0.0.0Toke Høiland-Jørgensen1-0/+3
[ Upstream commit 321827477360934dc040e9d3c626bf1de6c3ab3c ] When constructing ICMP response messages, the kernel will try to pick a suitable source address for the outgoing packet. However, if no IPv4 addresses are configured on the system at all, this will fail and we end up producing an ICMP message with a source address of 0.0.0.0. This can happen on a box routing IPv4 traffic via v6 nexthops, for instance. Since 0.0.0.0 is not generally routable on the internet, there's a good chance that such ICMP messages will never make it back to the sender of the original packet that the ICMP message was sent in response to. This, in turn, can create connectivity and PMTUd problems for senders. Fortunately, RFC7600 reserves a dummy address to be used as a source for ICMP messages (192.0.0.8/32), so let's teach the kernel to substitute that address as a last resort if the regular source address selection procedure fails. Below is a quick example reproducing this issue with network namespaces: ip netns add ns0 ip l add type veth peer netns ns0 ip l set dev veth0 up ip a add 10.0.0.1/24 dev veth0 ip a add fc00:dead:cafe:42::1/64 dev veth0 ip r add 10.1.0.0/24 via inet6 fc00:dead:cafe:42::2 ip -n ns0 l set dev veth0 up ip -n ns0 a add fc00:dead:cafe:42::2/64 dev veth0 ip -n ns0 r add 10.0.0.0/24 via inet6 fc00:dead:cafe:42::1 ip netns exec ns0 sysctl -w net.ipv4.icmp_ratelimit=0 ip netns exec ns0 sysctl -w net.ipv4.ip_forward=1 tcpdump -tpni veth0 -c 2 icmp & ping -w 1 10.1.0.1 > /dev/null tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on veth0, link-type EN10MB (Ethernet), snapshot length 262144 bytes IP 10.0.0.1 > 10.1.0.1: ICMP echo request, id 29, seq 1, length 64 IP 0.0.0.0 > 10.0.0.1: ICMP net 10.1.0.1 unreachable, length 92 2 packets captured 2 packets received by filter 0 packets dropped by kernel With this patch the above capture changes to: IP 10.0.0.1 > 10.1.0.1: ICMP echo request, id 31127, seq 1, length 64 IP 192.0.0.8 > 10.0.0.1: ICMP net 10.1.0.1 unreachable, length 92 Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Reported-by: Juliusz Chroboczek <jch@irif.fr> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Signed-off-by: David S.

[ Upstream commit 9c661b0b85444e426d3f23250305eeb16f6ffe88 ] One use case of PACKET_FANOUT is lockless reception with one socket per CPU. 256 is a practical limit on increasingly many machines. Increase PACKET_FANOUT_MAX to 64K. Expand setsockopt PACKET_FANOUT to take an extra argument max_num_members. Also explicitly define a fanout_args struct, instead of implicitly casting to an integer. This documents the API and simplifies the control flow. If max_num_members is not specified or is set to 0, then 256 is used, same as before.

2021-05-07capabilities: require CAP_SETFCAP to map uid 0Serge E. Hallyn1-1/+2
[ Upstream commit db2e718a47984b9d71ed890eb2ea36ecf150de18 ] cap_setfcap is required to create file capabilities. Since commit 8db6c34f1dbc ("Introduce v3 namespaced file capabilities"), a process running as uid 0 but without cap_setfcap is able to work around this as follows: unshare a new user namespace which maps parent uid 0 into the child namespace. While this task will not have new capabilities against the parent namespace, there is a loophole due to the way namespaced file capabilities are represented as xattrs. File capabilities valid in userns 1 are distinguished from file capabilities valid in userns 2 by the kuid which underlies uid 0. Therefore the restricted root process can unshare a new self-mapping namespace, add a namespaced file capability onto a file, then use that file capability in the parent namespace. To prevent that, do not allow mapping parent uid 0 if the process which opened the uid_map file does not have CAP_SETFCAP, which is the capability for setting file capabilities. As a further wrinkle: a task can unshare its user namespace, then open its uid_map file itself, and map (only) its own uid. In this case we do not have the credential from before unshare, which was potentially more restricted. So, when creating a user namespace, we record whether the creator had CAP_SETFCAP. Then we can use that during map_write(). With this patch: 1. Unprivileged user can still unshare -Ur ubuntu@caps:~$ unshare -Ur root@caps:~# logout 2. Root user can still unshare -Ur ubuntu@caps:~$ sudo bash root@caps:/home/ubuntu# unshare -Ur root@caps:/home/ubuntu# logout 3. Root user without CAP_SETFCAP cannot unshare -Ur: root@caps:/home/ubuntu# /sbin/capsh --drop=cap_setfcap -- root@caps:/home/ubuntu# /sbin/setcap cap_setfcap=p /sbin/setcap unable to set CAP_SETFCAP effective capability: Operation not permitted root@caps:/home/ubuntu# unshare -Ur unshare: write failed /proc/self/uid_map: Operation not permitted Note: an alternative solution would be to allow uid 0 mappings by processes without CAP_SETFCAP, but to prevent such a namespace from writing any file capabilities. This approach can be seen at [1]. Background history: commit 95ebabde382 ("capabilities: Don't allow writing ambiguous v3 file capabilities") tried to fix the issue by preventing v3 fscaps to be written to disk when the root uid would map to the same uid in nested user namespaces. This led to regressions for various workloads. For example, see [2]. Ultimately this is a valid use-case we have to support meaning we had to revert this change in 3b0c2d3eaa83 ("Revert 95ebabde382c ("capabilities: Don't allow writing ambiguous v3 file capabilities")").

2021-03-17net: l2tp: reduce log level of messages in receive path, add counter insteadMatthias Schiffer1-0/+1
commit 3e59e8856758eb5a2dfe1f831ef53b168fd58105 upstream. Commit 5ee759cda51b ("l2tp: use standard API for warning log messages") changed a number of warnings about invalid packets in the receive path so that they are always shown, instead of only when a special L2TP debug flag is set. Even with rate limiting these warnings can easily cause significant log spam - potentially triggered by a malicious party sending invalid packets on purpose. In addition these warnings were noticed by projects like Tunneldigger [1], which uses L2TP for its data path, but implements its own control protocol (which is sufficiently different from L2TP data packets that it would always be passed up to userspace even with future extensions of L2TP). Some of the warnings were already redundant, as l2tp_stats has a counter for these packets. This commit adds one additional counter for invalid packets that are passed up to userspace. Packets with unknown session are not counted as invalid, as there is nothing wrong with the format of these packets. With the additional counter, all of these messages are either redundant or benign, so we reduce them to pr_debug_ratelimited().

This could be surprising when introducing new layouts or options that take more than 4 bits, as this would silently drop the high bits. Make the masks consistent with the comment and the shift.
