Wdyt? _6_offset_to_skb_data is for sure not redundant. I don't test a partial fill from the most significant bits in my patch 13. u16_offset_to_skb_data is somewhat similar to fill_32bit_after_spill_64bit, but they aren't exactly the same: the former spills (u32)20 and fills (u16)20 (the same value), while my test spills (u64)0xXXXXXXXX00000000 and fills (u32)0 (the most significant bits are stripped). Maybe u16_offset_to_skb_data is redundant, but more coverage is better than less coverage, isn't it? > > diff --git a/tools/testing/selftests/bpf/progs/verifier_spill_fill.c b/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > index 809a09732168..de03e72e07a9 100644 > > --- a/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > +++ b/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > @@ -217,7 +217,7 @@ __naked void uninit_u32_from_the_stack(void) > > > > SEC("tc") > > __description("Spill a u32 const scalar.

[PATCH net-next v3 0/3] net: gro: reduce extension header parsing overhead

by Richard Gobert

This series attempts to reduce the parsing overhead of IPv6 extension headers in GRO and GSO, by removing extension header specific code and enabling the frag0 fast path. The following changes were made: - Removed some unnecessary HBH conditionals by adding HBH offload to inet6_offloads - Added a utility function to support frag0 fast path in ipv6_gro_receive - Added selftests for IPv6 packets with extension headers in GRO Richard v2 -> v3: - Removed previously added IPv6 extension header length constant and using sizeof(*opth) instead. - Removed unnecessary conditional in gro selftest framework - v2: https://lore.kernel.org/netdev/127b8199-1cd4-42d7-9b2b-875abaad93fe@gmail.c… v1 -> v2: - Added a minimum IPv6 extension header length constant to make code self documenting. - Added new selftest which checks that packets with different extension header payloads do not coalesce. - Added more info in the second commit message regarding the code changes. - v1: https://lore.kernel.org/netdev/f4eff69d-3917-4c42-8c6b-d09597ac4437@gmail.c… Richard Gobert (3): net: gso: add HBH extension header offload support net: gro: parse ipv6 ext headers without frag0 invalidation selftests/net: fix GRO coalesce test and add ext header coalesce tests net/ipv6/exthdrs_offload.c | 11 ++++ net/ipv6/ip6_offload.c | 76 +++++++++++++++++-------- tools/testing/selftests/net/gro.c | 93 +++++++++++++++++++++++++++++-- 3 files changed, 150 insertions(+), 30 deletions(-) -- 2.36.1

[PATCH v4 8/8] selftests/pcie_bwctrl: Create selftests

by Ilpo Järvinen

Create selftests for PCIe BW control through the PCIe cooling device sysfs interface. First, the BW control selftest finds the PCIe Port to test with. By default, the PCIe Port with the highest Link Speed is selected but another PCIe Port can be provided with -d parameter. The actual test steps the cur_state of the cooling device one-by-one from max_state to what the cur_state was initially. The speed change is confirmed by observing the current_link_speed for the corresponding PCIe Port.

[PATCH bpf-next 0/2] Annotate kfuncs in .BTF_ids section

by Daniel Xu

This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool. We store this metadata inside a yet-unused flags field inside struct btf_id_set8 (thanks Kumar!). pahole will be taught where to look. More details about the full chain of events are available in commit 2's description.

[PATCHv3 net-next 3/3] selftest/ptp: extend test to include ptp_gettimex64any()

by Mahesh Bandewar

Update testptp.c to exercise the new ptp method gettimex64any(). When only -x option is given the PTP_SYS_OFFSET_EXTENDED or gettimex64() method is exercised while presence of -x with -y will exercise PTP_SYS_OFFSET_ANY or gettimex64any() method. -y option is to choose the timebase from available options of real, mono, or raw.

[RFC PATCH v3 0/3] Add test to verify probe of devices from discoverable busses

by Nícolas F. R. A. Prado

Hi, for this v3 I changed the approach for identifying devices in a stable way from the match fields back to the hardware topology (used in v1). The match fields were proposed as a way to avoid the possible issue of PCI topology being reconfigured, but that wasn't observed on any real system so far. However using match fields does allow for a real issue if an external device similar to an internal one is connected to the system, which results in a change of the match count and therefore a test failure. So using the HW topology was chosen as the most reliable approach. The per-platform device description file now uses YAML following a suggestion from Chris Obbard, and the test script was re-written in python to handle the new YAML format. A second sample board file is also now included for an x86 platform, which contains an USB controller behind a PCI controller, which wasn't possible to describe in v1. Thanks, Nícolas v2: https://lore.kernel.org/all/20231127233558.868365-1-nfraprado@collabora.com v1: https://lore.kernel.org/all/20231024211818.365844-1-nfraprado@collabora.com Original cover letter: This is part of an effort to improve detection of regressions impacting device probe on all platforms. The recently merged DT kselftest [3] detects probe issues for all devices described statically in the DT. That leaves out devices discovered at run-time from discoverable busses. This is where this test comes in. All of the devices that are connected through discoverable busses (ie USB and PCI), and which are internal and therefore always present, can be described in a per-platform file so they can be checked for.

[PATCH] kunit: Protect string comparisons against NULL

by Richard Fitzgerald

Add NULL checks to KUNIT_BINARY_STR_ASSERTION() so that it will fail cleanly if either pointer is NULL, instead of causing a NULL pointer dereference in the strcmp(). A test failure could be that a string is unexpectedly NULL. This could be trapped by KUNIT_ASSERT_NOT_NULL() but that would terminate the test at that point. It's preferable that the KUNIT_EXPECT_STR*() macros can handle NULL pointers as a failure.

[PATCH v4 00/11] RISCV: Add kvm Sstc timer selftests

by Haibo Xu

The RISC-V arch_timer selftests is used to validate Sstc timer functionality in a guest, which sets up periodic timer interrupts and check the basic interrupt status upon its receipt. This KVM selftests was ported from aarch64 arch_timer and tested with Linux v6.7-rc4 on a Qemu riscv64 virt machine. --- Changed since v4: * Rebased to Linux 6.7-rc4 * Included Paolo's patch(01/11) to fix issues with SPLIT_TESTS * Droped the patch(KVM: selftests: Unify the makefile rule for split targets) since Paolo's patch had included the fix * Added new patch(05/11) to include header file vdso/processor.h from linux source tree to leverage the cpu_relax() definition - Conor/Andrew * Added new patch(11/11) to enable user configuration of timer error margin parameter which alleviate the intermitent failure in stress test - Andrew * Other minor fixes per Andrew's comments Haibo Xu (10): KVM: arm64: selftests: Split arch_timer test code KVM: selftests: Add CONFIG_64BIT definition for the build tools: riscv: Add header file csr.h tools: riscv: Add header file vdso/processor.h KVM: riscv: selftests: Switch to use macro from csr.h KVM: riscv: selftests: Add exception handling support KVM: riscv: selftests: Add guest helper to get vcpu id KVM: riscv: selftests: Change vcpu_has_ext to a common function KVM: riscv: selftests: Add sstc timer test KVM: selftests: Enable tunning of err_margin_us in arch timer test Paolo Bonzini (1): selftests/kvm: Fix issues with $(SPLIT_TESTS) tools/arch/riscv/include/asm/csr.h | 521 ++++++++++++++++++ tools/arch/riscv/include/asm/vdso/processor.h | 32 ++ tools/testing/selftests/kvm/Makefile | 27 +- .../selftests/kvm/aarch64/arch_timer.c | 295 +--------- tools/testing/selftests/kvm/arch_timer.c | 259 +++++++++ .../selftests/kvm/include/aarch64/processor.h | 4 - .../selftests/kvm/include/kvm_util_base.h | 9 + .../selftests/kvm/include/riscv/arch_timer.h | 71 +++ .../selftests/kvm/include/riscv/processor.h | 65 ++- .../testing/selftests/kvm/include/test_util.h | 2 + .../selftests/kvm/include/timer_test.h | 45 ++ .../selftests/kvm/lib/riscv/handlers.S | 101 ++++ .../selftests/kvm/lib/riscv/processor.c | 87 +++ .../testing/selftests/kvm/riscv/arch_timer.c | 111 ++++ .../selftests/kvm/riscv/get-reg-list.c | 11 +- 15 files changed, 1333 insertions(+), 307 deletions(-) create mode 100644 tools/arch/riscv/include/asm/csr.h create mode 100644 tools/arch/riscv/include/asm/vdso/processor.h create mode 100644 tools/testing/selftests/kvm/arch_timer.c create mode 100644 tools/testing/selftests/kvm/include/riscv/arch_timer.h create mode 100644 tools/testing/selftests/kvm/include/timer_test.h create mode 100644 tools/testing/selftests/kvm/lib/riscv/handlers.S create mode 100644 tools/testing/selftests/kvm/riscv/arch_timer.c -- 2.34.1

[PATCH v2 net-next] selftests/net: change shebang to bash to support "source"

by Yujie Liu

The patch set [1] added a general lib.sh in net selftests, and converted several test scripts to source the lib.sh. unicast_extensions.sh (converted in [1]) and pmtu.sh (converted in [2]) have a /bin/sh shebang which may point to various shells in different distributions, but "source" is only available in some of them. For example, "source" is a built-it function in bash, but it cannot be used in dash. Refer to other scripts that were converted together, simply change the shebang to bash to fix the following issues when the default /bin/sh points to other shells. # selftests: net: unicast_extensions.sh # ./unicast_extensions.sh: 31: source: not found # ########################################################################### # Unicast address extensions tests (behavior of reserved IPv4 addresses) # ########################################################################### # TEST: assign and ping within 240/4 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 240/4 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping inside 255.255/16 (is allowed) [FAIL] # TEST: assign and ping inside 255.255.255/24 (is allowed) [FAIL] # TEST: route between 240.5.6/24 and 255.1.2/24 (is allowed) [FAIL] # TEST: route between 0.200/16 and 245.99/16 (is allowed) [FAIL] # TEST: assign and ping lowest address (/24) [FAIL] # TEST: assign and ping lowest address (/26) [FAIL] # TEST: routing using lowest address [FAIL] # TEST: assigning 0.0.0.0 (is forbidden) [ OK ] # TEST: assigning 255.255.255.255 (is forbidden) [ OK ] # TEST: assign and ping inside 127/8 (is forbidden) [ OK ] # TEST: assign and ping class D address (is forbidden) [ OK ] # TEST: routing using class D (is forbidden) [ OK ] # TEST: routing using 127/8 (is forbidden) [ OK ] not ok 51 selftests: net: unicast_extensions.sh # exit=1 v1 -> v2: - Fix pmtu.sh which has the same issue as unicast_extensions.sh, suggested by Hangbin - Change the style of the "source" line to be consistent with other tests, suggested by Hangbin Link: https://lore.kernel.org/all/20231202020110.362433-1-liuhangbin@gmail.com/ [1] Link: https://lore.kernel.org/all/20231219094856.1740079-1-liuhangbin@gmail.com/ [2] Reported-by: kernel test robot <oliver.sang(a)intel.com> Signed-off-by: Yujie Liu <yujie.liu(a)intel.com> --- tools/testing/selftests/net/pmtu.sh | 4 ++-- tools/testing/selftests/net/unicast_extensions.sh | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/net/pmtu.sh b/tools/testing/selftests/net/pmtu.sh index 175d3d1d773b..f10879788f61 100755 --- a/tools/testing/selftests/net/pmtu.sh +++ b/tools/testing/selftests/net/pmtu.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # Check that route PMTU values match expectations, and that initial device MTU @@ -198,7 +198,7 @@ # - pmtu_ipv6_route_change # Same as above but with IPv6 -source ./lib.sh +source lib.sh PAUSE_ON_FAIL=no VERBOSE=0 diff --git a/tools/testing/selftests/net/unicast_extensions.sh b/tools/testing/selftests/net/unicast_extensions.sh index b7a2cb9e7477..f52aa5f7da52 100755 --- a/tools/testing/selftests/net/unicast_extensions.sh +++ b/tools/testing/selftests/net/unicast_extensions.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # By Seth Schoen (c) 2021, for the IPv4 Unicast Extensions Project @@ -28,7 +28,7 @@ # These tests provide an easy way to flip the expected result of any # of these behaviors for testing kernel patches that change them. -source ./lib.sh +source lib.sh # nettest can be run from PATH or from same directory as this selftest if ! which nettest >/dev/null; then base-commit: cd4d7263d58ab98fd4dee876776e4da6c328faa3 -- 2.34.1
