2022-02-11bpftool: Generalize light skeleton generation.Alexei Starovoitov1-19/+20
Generealize light skeleton by hiding mmap details in skel_internal.h In this form generated lskel.h is usable both by user space and by the kernel. Note that previously #include <bpf/bpf.h> was in *.lskel.h file. To avoid #ifdef-s in a generated lskel.h the include of bpf.h is moved to skel_internal.h, but skel_internal.h is also used by gen_loader.c which is part of libbpf. Therefore skel_internal.h does #include "bpf.h" in case of user space, so gen_loader.c and lskel.h have necessary definitions.

2022-02-11libbpf: Prepare light skeleton for the kernel.Alexei Starovoitov2-21/+179
Prepare light skeleton to be used in the kernel module and in the user space. The look and feel of lskel.h is mostly the same with the difference that for user space the skel->rodata is the same pointer before and after skel_load operation, while in the kernel the skel->rodata after skel_open and the skel->rodata after skel_load are different pointers. Typical usage of skeleton remains the same for kernel and user space: skel = my_bpf__open(); skel->rodata->my_global_var = init_val; err = my_bpf__load(skel); err = my_bpf__attach(skel); // access skel->rodata->my_global_var; // access skel->bss->another_var; Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Yonghong Song <yhs@fb.com> Acked-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20220209232001.27490-3-alexei.starovoitov@gmail.com

2022-02-10net: dsa: mv88e6xxx: fix use-after-free in mv88e6xxx_mdios_unregisterVladimir Oltean1-2/+2
Since struct mv88e6xxx_mdio_bus *mdio_bus is the bus->priv of something allocated with mdiobus_alloc_size(), this means that mdiobus_free(bus) will free the memory backing the mdio_bus as well. Therefore, the mdio_bus->list element is freed memory, but we continue to iterate through the list of MDIO buses using that list element. To fix this, use the proper list iterator that handles element deletion by keeping a copy of the list element next pointer.

2022-02-10KVM: x86/xen: Fix runstate updates to be atomic when preempting vCPUDavid Woodhouse1-30/+67
There are circumstances whem kvm_xen_update_runstate_guest() should not sleep because it ends up being called from __schedule() when the vCPU is preempted: [ 222.830825] kvm_xen_update_runstate_guest+0x24/0x100 [ 222.830878] kvm_arch_vcpu_put+0x14c/0x200 [ 222.830920] kvm_sched_out+0x30/0x40 [ 222.830960] __schedule+0x55c/0x9f0 To handle this, make it use the same trick as __kvm_xen_has_interrupt(), of using the hva from the gfn_to_hva_cache directly. Then it can use pagefault_disable() around the accesses and just bail out if the page is absent (which is unlikely). I almost switched to using a gfn_to_pfn_cache here and bailing out if kvm_map_gfn() fails, like kvm_steal_time_set_preempted() does — but on closer inspection it looks like kvm_map_gfn() will *always* fail in atomic context for a page in IOMEM, which means it will silently fail to make the update every single time for such guests, AFAICT. So I didn't do it that way after all. And will probably fix that one too.

2022-02-10riscv: fix build with binutils 2.38Aurelien Jarno1-0/+6
From version 2.38, binutils default to ISA spec version 20191213. This means that the csr read/write (csrr*/csrw*) instructions and fence.i instruction has separated from the `I` extension, become two standalone extensions: Zicsr and Zifencei. As the kernel uses those instruction, this causes the following build failure: CC arch/riscv/kernel/vdso/vgettimeofday.o <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h: Assembler messages: <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' The fix is to specify those extensions explicitely in -march.

2022-02-10ice: Avoid RTNL lock when re-creating auxiliary deviceDave Ertman2-1/+5
If a call to re-create the auxiliary device happens in a context that has already taken the RTNL lock, then the call flow that recreates auxiliary device can hang if there is another attempt to claim the RTNL lock by the auxiliary driver. To avoid this, any call to re-create auxiliary devices that comes from an source that is holding the RTNL lock (e.g. netdev notifier when interface exits a bond) should execute in a separate thread. To accomplish this, add a flag to the PF that will be evaluated in the service task and dealt with there.

2022-02-10ice: Fix KASAN error in LAG NETDEV_UNREGISTER handlerDave Ertman1-6/+28
Currently, the same handler is called for both a NETDEV_BONDING_INFO LAG unlink notification as for a NETDEV_UNREGISTER call. This is causing a problem though, since the netdev_notifier_info passed has a different structure depending on which event is passed. The problem manifests as a call trace from a BUG: KASAN stack-out-of-bounds error. Fix this by creating a handler specific to NETDEV_UNREGISTER that only is passed valid elements in the netdev_notifier_info struct for the NETDEV_UNREGISTER event. Also included is the removal of an unbalanced dev_put on the peer_netdev and related braces.

2022-02-10ice: fix IPIP and SIT TSO offloadJesse Brandeburg2-8/+18
The driver was avoiding offload for IPIP (at least) frames due to parsing the inner header offsets incorrectly when trying to check lengths. This length check works for VXLAN frames but fails on IPIP frames because skb_transport_offset points to the inner header in IPIP frames, which meant the subtraction of transport_header from inner_network_header returns a negative value (-20). With the code before this patch, everything continued to work, but GSO was being used to segment, causing throughputs of 1.5Gb/s per thread. After this patch, throughput is more like 10Gb/s per thread for IPIP traffic.

Commit 563f8e97e054 ("ipv4: Stop taking ECN bits into account in fib4-rules") replaced the validation test on frh->tos. While the new test is stricter for ECN bits, it doesn't detect the use of high order DSCP bits. This would be fine if IPv4 could properly handle them. But currently, most IPv4 lookups are done with the three high DSCP bits masked. Therefore, using these bits doesn't lead to the expected result. Let's reject such configurations again, so that nobody starts to use and make any assumption about how the stack handles the three high order DSCP bits in fib4 rules.

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.

There is more ongoing in ieee802154 than usual. This will be the first pull request for this cycle, but I expect one more. Depending on review and rework times. Pavel Skripkin ported the atusb driver over to the new USB api to avoid unint problems as well as making use of the modern api without kmalloc() needs in he driver. Miquel Raynal landed some changes to ensure proper frame checksum checking with hwsim, documenting our use of wake and stop_queue and eliding a magic value by using the proper define. David Girault documented the address struct used in ieee802154. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2022-02-10tipc: improve size validations for received domain recordsJon Maloy2-2/+9
The function tipc_mon_rcv() allows a node to receive and process domain_record structs from peer nodes to track their views of the network topology. This patch verifies that the number of members in a received domain record does not exceed the limit defined by MAX_MON_DOMAIN, something that may otherwise lead to a stack overflow. tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where we are reading a 32 bit message data length field into a uint16. To avert any risk of bit overflow, we add an extra sanity check for this in that function. We cannot see that happen with the current code, but future designers being unaware of this risk, may introduce it by allowing delivery of very large (> 64k) sk buffers from the bearer layer. This potential problem was identified by Eric Dumazet.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== 100GbE Intel Wired LAN Driver Updates 2022-02-09 This series contains updates to ice driver only. Brett adds support for QinQ. This begins with code refactoring and re-organization of VLAN configuration functions to allow for introduction of VSI VLAN ops to enable setting and calling of respective operations based on device support of single or double VLANs. Implementations are added for outer VLAN support. To support QinQ, the device must be set to double VLAN mode (DVM). In order for this to occur, the DDP package and NVM must also support DVM. Functions to determine compatibility and properly configure the device are added as well as setting the proper bits to advertise and utilize the proper offloads. Support for VIRTCHNL_VF_OFFLOAD_VLAN_V2 is also included to allow for VF to negotiate and utilize this functionality. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2022-02-10xen/x86: detect support for extended destination IDRoger Pau Monne2-0/+13
Xen allows the usage of some previously reserved bits in the IO-APIC RTE and the MSI address fields in order to store high bits for the target APIC ID. Such feature is already implemented by QEMU/KVM and HyperV, so in order to enable it just add the handler that checks for it's presence.
