Generalize NFT_META_IIFTYPE to NFT_META_IFTYPE which allows you to match on the interface type of the skb->dev field. This field is used by the netdev family to add an implicit dependency to skip non-ethernet packets when matching on layer 3 and 4 TCP/IP header fields. For backward compatibility, add the NFT_META_IIFTYPE alias to NFT_META_IFTYPE. Add __NFT_META_IIFTYPE, to be used by userspace in the future to match specifically on the iiftype.

The Chrome EC's features are returned through an ec_response_get_features struct, but they are stored in an independent array.

2021-10-30task_stack: Fix end_of_stack() for architectures with upwards-growing stackHelge Deller
The function end_of_stack() returns a pointer to the last entry of a stack. For architectures like parisc where the stack grows upwards return the pointer to the highest address in the stack. Without this change I faced a crash on parisc, because the stackleak functionality wrote STACKLEAK_POISON to the lowest address and thus overwrote the first 4 bytes of the task_struct which included the TIF_FLAGS.

2021-10-30locking: Remove spin_lock_flags() etcArnd Bergmann
parisc, ia64 and powerpc32 are the only remaining architectures that provide custom arch_{spin,read,write}_lock_flags() functions, which are meant to re-enable interrupts while waiting for a spinlock. However, none of these can actually run into this codepath, because it is only called on architectures without CONFIG_GENERIC_LOCKBREAK, or when CONFIG_DEBUG_LOCK_ALLOC is set without CONFIG_LOCKDEP, and none of those combinations are possible on the three architectures. Going back in the git history, it appears that arch/mn10300 may have been able to run into this code path, but there is a good chance that it never worked. On the architectures that still exist, it was already impossible to hit back in 2008 after the introduction of CONFIG_GENERIC_LOCKBREAK, and possibly earlier. As this is all dead code, just remove it and the helper functions built around it. For arch/ia64, the inline asm could be cleaned up, but it seems safer to leave it untouched.

2021-10-29mailbox: pcc: Use PCC mailbox channel pointer instead of standardSudeep Holla
Now that we have all the shared memory region information populated in the pcc_mbox_chan, let us propagate the pointer to the same as the return value to pcc_mbox_request channel. This eliminates the need for the individual users of PCC mailbox to parse the PCCT subspace entries and fetch the shmem information. This also eliminates the need for PCC mailbox controller to set con_priv to PCCT subspace entries. This is required as con_priv is private to the controller driver to attach private data associated with the channel and not meant to be used by the mailbox client/users. Let us convert all the users of pcc_mbox_{request,free}_channel to use new interface.

2021-10-29mailbox: pcc: Add pcc_mbox_chan structure to hold shared memory region infoSudeep Holla
Currently PCC mailbox controller sets con_priv in each channel to hold the pointer to pcct subspace entry it corresponds to. The mailbox user will then fetch this pointer from the channel descriptor they get when they request for the channel. Using that pointer they then parse the pcct entry again to fetch all the information about shared memory region. In order to remove individual users of PCC mailbox parsing the PCCT subspace entries to fetch same information, let us consolidate the same in pcc mailbox controller by parsing all the shared memory region information into a structure that can also hold the mbox_chan pointer it represent. This can then be used as main PCC mailbox channel pointer that we can return as part of pcc_mbox_request_channel instead of standard mailbox channel pointer.

2021-10-29net/mlx5: Allow skipping counter refresh on creationPaul Blakey
CT creates a counter for each CT rule, and for each such counter, fs_counters tries to queue mlx5_fc_stats_work() work again via mod_delayed_work(0) call to refresh all counters. This call has a large performance impact when reaching high insertion rate and accounts for ~8% of the insertion time when using software steering. Allow skipping the refresh of all counters during counter creation. Change CT to use this refresh skipping for it's counters.

2021-10-29signal: Implement force_fatal_sigEric W. Biederman
Add a simple helper force_fatal_sig that causes a signal to be delivered to a process as if the signal handler was set to SIG_DFL. Reimplement force_sigsegv based upon this new helper. This fixes force_sigsegv so that when it forces the default signal handler to be used the code now forces the signal to be unblocked as well. Reusing the tested logic in force_sig_info_to_task that was built for force_sig_seccomp this makes the implementation trivial. This is interesting both because it makes force_sigsegv simpler and because there are a couple of buggy places in the kernel that call do_exit(SIGILL) or do_exit(SIGSYS) because there is no straight forward way today for those places to simply force the exit of a process with the chosen signal. Creating force_fatal_sig allows those places to be implemented with normal signal exits. Link: https://lkml.kernel.org/r/20211020174406.17889-13-ebiederm@xmission.com Signed-off-by: Eric W.

2021-10-29Bluetooth: Add helper for serialized HCI command executionMarcel Holtmann
The usage of __hci_cmd_sync() within the hdev->setup() callback allows for a nice and simple serialized execution of HCI commands. More importantly it allows for result processing before issueing the next command. With the current usage of hci_req_run() it is possible to batch up commands and execute them, but it is impossible to react to their results or errors. This is an attempt to generalize the hdev->setup() handling and provide a simple way of running multiple HCI commands from a single function context. There are multiple struct work that are decdicated to certain tasks already used right now. It is add a lot of bloat to hci_dev struct and extra handling code. So it might be possible to put all of these behind a common HCI command infrastructure and just execute the HCI commands from the same work context in a serialized fashion. For example updating the white list and resolving list can be done now without having to know the list size ahead of time. Also preparing for suspend or resume shouldn't require a state machine anymore. There are other tasks that should be simplified as well.

Export the following additional ECC helper functions: - ecc_alloc_point() - ecc_free_point() - vli_num_bits() - ecc_point_is_zero() This is done to allow future ECC device drivers to re-use existing code, thus simplifying their implementation. Functions are exported using EXPORT_SYMBOL() (instead of EXPORT_SYMBOL_GPL()) to be consistent with the functions already exported by crypto/ecc.c. Exported functions are documented in include/crypto/internal/ecc.h. Signed-off-by: Daniele Alessandrelli <daniele.alessandrelli@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2021-10-29cls_flower: Fix inability to match GRE/IPIP packetsYoshiki Komachi
When a packet of a new flow arrives in openvswitch kernel module, it dissects the packet and passes the extracted flow key to ovs-vswtichd daemon. If hw- offload configuration is enabled, the daemon creates a new TC flower entry to bypass openvswitch kernel module for the flow (TC flower can also offload flows to NICs but this time that does not matter). In this processing flow, I found the following issue in cases of GRE/IPIP packets. When ovs_flow_key_extract() in openvswitch module parses a packet of a new GRE (or IPIP) flow received on non-tunneling vports, it extracts information of the outer IP header for ip_proto/src_ip/dst_ip match keys. This means ovs-vswitchd creates a TC flower entry with IP protocol/addresses match keys whose values are those of the outer IP header. OTOH, TC flower, which uses flow_dissector (different parser from openvswitch module), extracts information of the inner IP header. The following flow is an example to describe the issue in more detail. <----------- Outer IP -----------------> <---------- Inner IP ----------> +----------+--------------+--------------+----------+----------+----------+ | ip_proto | src_ip | dst_ip | ip_proto | src_ip | dst_ip | | 47 (GRE) | 192.168.10.1 | 192.168.10.2 | 6 (TCP) | 10.0.0.1 | 10.0.0.2 | +----------+--------------+--------------+----------+----------+----------+ In this case, TC flower entry and extracted information are shown as below: - ovs-vswitchd creates TC flower entry with: - ip_proto: 47 - src_ip: 192.168.10.1 - dst_ip: 192.168.10.2 - TC flower extracts below for IP header matches: - ip_proto: 6 - src_ip: 10.0.0.1 - dst_ip: 10.0.0.2 Thus, GRE or IPIP packets never match the TC flower entry, as each dissector behaves differently. IMHO, the behavior of TC flower (flow dissector) does not look correct, as ip_proto/src_ip/dst_ip in TC flower match means the outermost IP header information except for GRE/IPIP cases. This patch adds a new flow_dissector flag FLOW_DISSECTOR_F_STOP_BEFORE_ENCAP which skips dissection of the encapsulated inner GRE/IPIP header in TC flower classifier.

The header file include/uapi/linux/bcache.h is not really a user space API heaer. This file defines the ondisk format of bcache internal meta data but no one includes it from user space, bcache-tools has its own copy of this header with minor modification.

This change adds a new skb extension for MCTP, to represent a request/response flow. The intention is to use this in a later change to allow i2c controllers to correctly configure a multiplexer over a flow. Since we have a cleanup function in the core path (if an extension is present), we'll need to make CONFIG_MCTP a bool, rather than a tristate.
