2022-11-11ptp: convert remaining drivers to adjfine interfaceJacob Keller1-5/+8
Convert all remaining drivers that still use .adjfreq to the newer .adjfine implementation. These drivers are not straightforward, as they use non-standard methods of programming their hardware. They are all converted to use scaled_ppm_to_ppb to get the parts per billion value that their logic depends on.

2022-07-12qlogic: qed: fix clang -Wformat warningsJustin Stitt1-2/+2
When building with Clang we encounter these warnings: | drivers/net/ethernet/qlogic/qed/qed_dev.c:416:30: error: format | specifies type 'char' but the argument has type 'u32' (aka 'unsigned | int') [-Werror,-Wformat] i); - | drivers/net/ethernet/qlogic/qed/qed_dev.c:630:13: error: format | specifies type 'char' but the argument has type 'int' [-Werror,-Wformat] | p_llh_info->num_ppfid - 1); For the first warning, `i` is a u32 which is much wider than the format specifier `%hhd` describes. This results in a loss of bits after 2^7. The second warning involves implicit integer promotion as the resulting type of addition cannot be smaller than an int. example: `` uint8_t a = 4, b = 7; int size = sizeof(a + b - 1); printf("%d\n", size); // output: 4 ``` See more: (https://wiki.sei.cmu.edu/confluence/display/c/INT02-C.+Understand+integer+conversion+rules) "Integer types smaller than int are promoted when an operation is performed on them. If all values of the original type can be represented as an int, the value of the smaller type is converted to an int; otherwise, it is converted to an unsigned int."

2022-05-17net/qla3xxx: Fix a test in ql_reset_work()Christophe JAILLET1-1/+2
test_bit() tests if one bit is set or not. Here the logic seems to check of bit QL_RESET_PER_SCSI (i.e. 4) OR bit QL_RESET_START (i.e. 3) is set. In fact, it checks if bit 7 (4 | 3 = 7) is set, that is to say QL_ADAPTER_UP. This looks harmless, because this bit is likely be set, and when the ql_reset_work() delayed work is scheduled in ql3xxx_isr() (the only place that schedule this work), QL_RESET_START or QL_RESET_PER_SCSI is set. This has been spotted by smatch.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "The sprinkling of SPI drivers is because we added a new one and Mark sent us a SPI driver interface conversion pull request. Core ---- - Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO). - Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order. - Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect). - Continue the work of annotating packet drop reasons throughout the stack. - Switch netdev error counters from an atomic to dynamically allocated per-CPU counters. - Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT. - Extend the ref_tracker to allow catching use-after-free bugs. BPF --- - Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split. - Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers. - Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency. - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator. - Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep. - Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later). - Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra. - Allow cgroup BPF progs to return custom errors to user space. - Add support for AF_UNIX iterator batching. - Allow iterator programs to use sleepable helpers. - Support JIT of add, and, or, xor and xchg atomic ops on arm64. - Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info. - Large number of libbpf API improvements, cleanups and deprecations. Protocols --------- - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev. - Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames. - Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior. - VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge. - Support inserting IPv6 IOAM information to a fraction of frames. - Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.) - Support setting socket and IPv6 options via cmsg on ping6 sockets. - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS. Define dscp_t and stop taking ECN bits into account in fib-rules. - Add support for locked bridge ports (for 802.1X). - tun: support NAPI for packets received from batched XDP buffs, doubling the performance in some scenarios. - IPv6 extension header handling in Open vSwitch. - Support IPv6 control message load balancing in bonding, prevent neighbor solicitation and advertisement from using the wrong port.

2022-02-17treewide: Replace zero-length arrays with flexible-array membersGustavo A. R. Silva1-1/+1
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ...

2022-02-10qed: prevent a fw assert during device shutdownVenkata Sudheer Kumar Bhavaraju3-2/+51
Device firmware can assert if the device shutdown path in driver encounters an async. events from mfw (processed in qed_mcp_handle_events()) after qed_mcp_unload_req() returns. A call to qed_mcp_unload_req() currently marks the device as inactive and thus stops any new events, but there is a windows where in-flight events might still be received by the driver. To prevent this race condition, atomically set QED_MCP_BYPASS_PROC_BIT in qed_mcp_unload_req() to make sure qed_mcp_handle_events() ignores all events. Wait for any event that might already be in-process to complete by monitoring QED_MCP_IN_PROCESSING_BIT.

2021-12-18qlcnic: potential dereference null pointer of rx_queue->page_ringJiasheng Jiang3-5/+13
The return value of kcalloc() needs to be checked. To avoid dereference of null pointer in case of the failure of alloc. Therefore, it might be better to change the return type of qlcnic_sriov_alloc_vlans() and return -ENOMEM when alloc fails and return 0 the others. Also, qlcnic_sriov_set_guest_vlan_mode() and __qlcnic_pci_sriov_enable() should deal with the return value of qlcnic_sriov_alloc_vlans().

2021-12-14net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEXHangbin Liu1-5/+0
Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device") the user could get bond active interface's PHC index directly. But when there is a failover, the bond active interface will change, thus the PHC index is also changed. This may break the user's program if they did not update the PHC timely. This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX. When the user wants to get the bond active interface's PHC, they need to add this flag and be aware the PHC index may be changed. With the new flag. All flag checks in current drivers are removed. Only the checking in net_hwtstamp_validate() is kept. Suggested-by: Jakub Kicinski <[email protected]> Signed-off-by: Hangbin Liu <[email protected]> Signed-off-by: David S.
