2019-11-27bpf: Support pre-2.25-binutils objcopy for vmlinux BTFStanislav Fomichev
If vmlinux BTF generation fails, but CONFIG_DEBUG_INFO_BTF is set, .BTF section of vmlinux is empty and kernel will prohibit BPF loading and return "in-kernel BTF is malformed". --dump-section argument to binutils' objcopy was added in version 2.25. When using pre-2.25 binutils, BTF generation silently fails. Convert to --only-section which is present on pre-2.25 binutils. Documentation/process/changes.rst states that binutils 2.21+ is supported, not sure those standards apply to BPF subsystem. v2: * exit and print an error if gen_btf fails (John Fastabend) v3: * resend with Andrii's Acked-by/Tested-by tags Fixes: 341dfcf8d78ea ("btf: expose BTF info through sysfs") Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Tested-by: Andrii Nakryiko <andriin@fb.com> Acked-by: Andrii Nakryiko <andriin@fb.com> Cc: John Fastabend <john.fastabend@gmail.com> Link: https://lore.kernel.org/bpf/20191127161410.57327-1-sdf@google.com

2019-11-26gve: Fix the queue page list allocated pages countJeroen de Borst
In gve_alloc_queue_page_list(), when a page allocation fails, qpl->num_entries will be wrong. In this case priv->num_registered_pages can underflow in gve_free_queue_page_list(), causing subsequent calls to gve_alloc_queue_page_list() to fail.

2019-11-26openvswitch: fix flow command message sizePaolo Abeni
When user-space sets the OVS_UFID_F_OMIT_* flags, and the relevant flow has no UFID, we can exceed the computed size, as ovs_nla_put_identifier() will always dump an OVS_FLOW_ATTR_KEY attribute. Take the above in account when computing the flow command message size. Fixes: 74ed7ab9264c ("openvswitch: Add support for unique flow IDs.")

2019-11-26net: psample: fix skb_over_panicNikolay Aleksandrov
We need to calculate the skb size correctly otherwise we risk triggering skb_over_panic[1]. The issue is that data_len is added to the skb in a nl attribute, but we don't account for its header size (nlattr 4 bytes) and alignment. We account for it when calculating the total size in the > PSAMPLE_MAX_PACKET_SIZE comparison correctly, but not when allocating after that. The fix is simple - use nla_total_size() for data_len when allocating. To reproduce: $ tc qdisc add dev eth1 clsact $ tc filter add dev eth1 egress matchall action sample rate 1 group 1 trunc 129 $ mausezahn eth1 -b bcast -a rand -c 1 -p 129 < skb_over_panic BUG(), tail is 4 bytes past skb->end > [1] Trace: [ 50.459526][ T3480] skbuff: skb_over_panic: text:(____ptrval____) len:196 put:136 head:(____ptrval____) data:(____ptrval____) tail:0xc4 end:0xc0 dev:<NULL> [ 50.474339][ T3480] ------------[ cut here ]------------ [ 50.481132][ T3480] kernel BUG at net/core/skbuff.c:108!

2019-11-26net: port < inet_prot_sock(net) --> inet_port_requires_bind_service(net, port)Maciej Żenczykowski
Note that the sysctl write accessor functions guarantee that: net->ipv4.sysctl_ip_prot_sock <= net->ipv4.ip_local_ports.range[0] invariant is maintained, and as such the max() in selinux hooks is actually spurious. ie. even though if (snum < max(inet_prot_sock(sock_net(sk)), low) || snum > high) { per logic is the same as if ((snum < inet_prot_sock(sock_net(sk)) && snum < low) || snum > high) { it is actually functionally equivalent to: if (snum < low || snum > high) { which is equivalent to: if (snum < inet_prot_sock(sock_net(sk)) || snum < low || snum > high) { even though the first clause is spurious. But we want to hold on to it in case we ever want to change what what inet_port_requires_bind_service() means (for example by changing it from a, by default, [0..1024) range to some sort of set).

Thomas Falcon says: ==================== ibmvnic: Harden device commands and queries This patch series fixes some shortcomings with the current VNIC device command implementation. The first patch fixes the initialization of driver completion structures used for device commands. Additionally, all waits for device commands are bounded with a timeout in the event that the device does not respond or becomes inoperable. Finally, serialize queries to retain the integrity of device return codes. Changes in v2: - included header comment for ibmvnic_wait_for_completion - removed open-coded loop in patch 3/4, suggested by Jakub - ibmvnic_wait_for_completion accepts timeout value in milliseconds instead of jiffies - timeout calculations cleaned up and completed before wait loop - included missing mutex_destroy calls, suggested by Jakub - included comment before mutex declaration ==================== Signed-off-by: David S.

The fdinfo file has now gained a new "NSpid:\t<ns-pid1>[\t<ns-pid2>[...]]" field which lists the pids of the process in all child pid namespaces provided the pid namespace of the procfs instance it is looked up under has an ancestoral relationship with the pid namespace of the process. If it does not 0 will be shown and no further pid namespaces will be listed. Tests included. (Christian Kellner) - If the process the pidfd references has already exited, print -1 for the Pid and NSpid fields in the pidfd's fdinfo file. Tests included. (me) - Add CLONE_CLEAR_SIGHAND. This lets callers clear all signal handler that are not SIG_DFL or SIG_IGN at process creation time. This originated as a feature request from glibc to improve performance and elimate races in their posix_spawn() implementation. Tests included. (me) - Add support for choosing a specific pid for a process with clone3(). This is the feature which was part of the thread update for v5.4 but after a discussion at LPC in Lisbon we decided to delay it for one more cycle in order to make the interface more generic. This has now done. It is now possible to choose a specific pid in a whole pid namespaces (sub)hierarchy instead of just one pid namespace. In order to choose a specific pid the caller must have CAP_SYS_ADMIN in all owning user namespaces of the target pid namespaces. Tests included. (Adrian Reber) - Test improvements and extensions.

Summary: - On ARMv8 CPUs without hardware updates of the access flag, avoid failing cow_user_page() on PFN mappings if the pte is old. The patches introduce an arch_faults_on_old_pte() macro, defined as false on x86. When true, cow_user_page() makes the pte young before attempting __copy_from_user_inatomic(). - Covert the synchronous exception handling paths in arch/arm64/kernel/entry.S to C. - FTRACE_WITH_REGS support for arm64. - ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4 - Several kselftest cases specific to arm64, together with a MAINTAINERS update for these files (moved to the ARM64 PORT entry). - Workaround for a Neoverse-N1 erratum where the CPU may fetch stale instructions under certain conditions. - Workaround for Cortex-A57 and A72 errata where the CPU may speculatively execute an AT instruction and associate a VMID with the wrong guest page tables (corrupting the TLB). - Perf updates for arm64: additional PMU topologies on HiSilicon platforms, support for CCN-512 interconnect, AXI ID filtering in the IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2. - GICv3 optimisation to avoid a heavy barrier when accessing the ICC_PMR_EL1 register. - ELF HWCAP documentation updates and clean-up. - SMC calling convention conduit code clean-up. - KASLR diagnostics printed during boot - NVIDIA Carmel CPU added to the KPTI whitelist - Some arm64 mm clean-ups: use generic free_initrd_mem(), remove stale macro, simplify calculation in __create_pgd_mapping(), typos. - Kconfig clean-ups: CMDLINE_FORCE to depend on CMDLINE, choice for endinanness to help with allmodconfig" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (93 commits) arm64: Kconfig: add a choice for endianness kselftest: arm64: fix spelling mistake "contiguos" -> "contiguous" arm64: Kconfig: make CMDLINE_FORCE depend on CMDLINE MAINTAINERS: Add arm64 selftests to the ARM64 PORT entry arm64: kaslr: Check command line before looking for a seed arm64: kaslr: Announce KASLR status on boot kselftest: arm64: fake_sigreturn_misaligned_sp kselftest: arm64: fake_sigreturn_bad_size kselftest: arm64: fake_sigreturn_duplicated_fpsimd kselftest: arm64: fake_sigreturn_missing_fpsimd kselftest: arm64: fake_sigreturn_bad_size_for_magic0 kselftest: arm64: fake_sigreturn_bad_magic kselftest: arm64: add helper get_current_context kselftest: arm64: extend test_init functionalities kselftest: arm64: mangle_pstate_invalid_mode_el[123][ht] kselftest: arm64: mangle_pstate_invalid_daif_bits kselftest: arm64: mangle_pstate_invalid_compat_toggle and common utils kselftest: arm64: extend toplevel skeleton Makefile drivers/perf: hisi: update the sccl_id/ccl_id for certain HiSilicon platform arm64: mm: reserve CMA and crashkernel in ZONE_DMA32 ...
