[PATCH v3 0/4] arm64/sme: ptrace support for TPIDR2_EL0

by Mark Brown

When SME was initially merged we did not add support for TPIDR2_EL0 to the ptrace interface, creating difficulties for debuggers in accessing lazy save state for ZA. This series implements that support, extending the existing NT_ARM_TLS regset to support the register when available, and adds kselftest coverage for the existing and new NT_ARM_TLS functionality. Existing programs that query the size of the register set will be able to observe the increased size of the register set. Programs that assume the register set is single register will see no change. On systems that do not support SME TPIDR2_EL0 will read as 0 and writes will be ignored, support for SME should be queried via hwcaps as normal. v3: - Fix copyright date on test program. v2: - Rebase onto v6.0-rc1.

[PATCH net v4 1/3] selftests: include bonding tests into the kselftest infra

by Jonathan Toppins

This creates a test collection in drivers/net/bonding for bonding specific kernel selftests. The first test is a reproducer that provisions a bond and given the specific order in how the ip-link(8) commands are issued the bond never transmits an LACPDU frame on any of its slaves. Signed-off-by: Jonathan Toppins <jtoppins(a)redhat.com> --- Notes: v2: * fully integrated the test into the kselftests infrastructure * moved the reproducer to under tools/testing/selftests/drivers/net/bonding * reduced the test to its minimial amount and used ip-link(8) for all bond interface configuration v3: * rebase to latest net/master * remove `#set -x` requested by Hangbin v4: * no changes MAINTAINERS | 1 + tools/testing/selftests/Makefile | 1 + .../selftests/drivers/net/bonding/Makefile | 6 ++ .../net/bonding/bond-break-lacpdu-tx.sh | 81 +++++++++++++++++++ .../selftests/drivers/net/bonding/config | 1 + .../selftests/drivers/net/bonding/settings | 1 + 6 files changed, 91 insertions(+) create mode 100644 tools/testing/selftests/drivers/net/bonding/Makefile create mode 100755 tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh create mode 100644 tools/testing/selftests/drivers/net/bonding/config create mode 100644 tools/testing/selftests/drivers/net/bonding/settings diff --git a/MAINTAINERS b/MAINTAINERS index f2d64020399b..e5fb14dc302d 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -3672,6 +3672,7 @@ F: Documentation/networking/bonding.rst F: drivers/net/bonding/ F: include/net/bond* F: include/uapi/linux/if_bonding.h +F: tools/testing/selftests/net/bonding/ BOSCH SENSORTEC BMA400 ACCELEROMETER IIO DRIVER M: Dan Robertson <dan(a)dlrobertson.com> diff --git a/tools/testing/selftests/Makefile b/tools/testing/selftests/Makefile index 10b34bb03bc1..c2064a35688b 100644 --- a/tools/testing/selftests/Makefile +++ b/tools/testing/selftests/Makefile @@ -12,6 +12,7 @@ TARGETS += cpu-hotplug TARGETS += damon TARGETS += drivers/dma-buf TARGETS += drivers/s390x/uvdevice +TARGETS += drivers/net/bonding TARGETS += efivarfs TARGETS += exec TARGETS += filesystems diff --git a/tools/testing/selftests/drivers/net/bonding/Makefile b/tools/testing/selftests/drivers/net/bonding/Makefile new file mode 100644 index 000000000000..ab6c54b12098 --- /dev/null +++ b/tools/testing/selftests/drivers/net/bonding/Makefile @@ -0,0 +1,6 @@ +# SPDX-License-Identifier: GPL-2.0 +# Makefile for net selftests + +TEST_PROGS := bond-break-lacpdu-tx.sh + +include ../../../lib.mk diff --git a/tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh b/tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh new file mode 100755 index 000000000000..47ab90596acb --- /dev/null +++ b/tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh @@ -0,0 +1,81 @@ +#!/bin/sh +# SPDX-License-Identifier: GPL-2.0 + +# Regression Test: +# Verify LACPDUs get transmitted after setting the MAC address of +# the bond. +# +# https://bugzilla.redhat.com/show_bug.cgi?id=2020773 +# +# +---------+ +# | fab-br0 | +# +---------+ +# | +# +---------+ +# | fbond | +# +---------+ +# | | +# +------+ +------+ +# |veth1 | |veth2 | +# +------+ +------+ +# +# We use veths instead of physical interfaces + +set -e +tmp=$(mktemp -q dump.XXXXXX) +cleanup() { + ip link del fab-br0 >/dev/null 2>&1 || : + ip link del fbond >/dev/null 2>&1 || : + ip link del veth1-bond >/dev/null 2>&1 || : + ip link del veth2-bond >/dev/null 2>&1 || : + modprobe -r bonding >/dev/null 2>&1 || : + rm -f -- ${tmp} +} + +trap cleanup 0 1 2 +cleanup +sleep 1 + +# create the bridge +ip link add fab-br0 address 52:54:00:3B:7C:A6 mtu 1500 type bridge \ + forward_delay 15 + +# create the bond +ip link add fbond type bond mode 4 miimon 200 xmit_hash_policy 1 \ + ad_actor_sys_prio 65535 lacp_rate fast + +# set bond address +ip link set fbond address 52:54:00:3B:7C:A6 +ip link set fbond up + +# set again bond sysfs parameters +ip link set fbond type bond ad_actor_sys_prio 65535 + +# create veths +ip link add name veth1-bond type veth peer name veth1-end +ip link add name veth2-bond type veth peer name veth2-end + +# add ports +ip link set fbond master fab-br0 +ip link set veth1-bond down master fbond +ip link set veth2-bond down master fbond + +# bring up +ip link set veth1-end up +ip link set veth2-end up +ip link set fab-br0 up +ip link set fbond up +ip addr add dev fab-br0 10.0.0.3 + +tcpdump -n -i veth1-end -e ether proto 0x8809 >${tmp} 2>&1 & +sleep 15 +pkill tcpdump >/dev/null 2>&1 +rc=0 +num=$(grep "packets captured" ${tmp} | awk '{print $1}') +if test "$num" -gt 0; then + echo "PASS, captured ${num}" +else + echo "FAIL" + rc=1 +fi +exit $rc diff --git a/tools/testing/selftests/drivers/net/bonding/config b/tools/testing/selftests/drivers/net/bonding/config new file mode 100644 index 000000000000..dc1c22de3c92 --- /dev/null +++ b/tools/testing/selftests/drivers/net/bonding/config @@ -0,0 +1 @@ +CONFIG_BONDING=y diff --git a/tools/testing/selftests/drivers/net/bonding/settings b/tools/testing/selftests/drivers/net/bonding/settings new file mode 100644 index 000000000000..867e118223cd --- /dev/null +++ b/tools/testing/selftests/drivers/net/bonding/settings @@ -0,0 +1 @@ +timeout=60 -- 2.31.1

[PATCH v2] selftests/net: Refactor xfrm_fill_key() to use array of structs

by Gautam Menghani

A TODO in net/ipsec.c asks to refactor the code in xfrm_fill_key() to use set/map to avoid manually comparing each algorithm with the "name" parameter passed to the function as an argument. This patch refactors the code to create an array of structs where each struct contains the algorithm name and its corresponding key length.

[PATCH v5 0/5] userfaultfd: add /dev/userfaultfd for fine grained access control

by Axel Rasmussen

This series is based on torvalds/master. The series is split up like so: - Patch 1 is a simple fixup which we should take in any case (even by itself). - Patches 2-5 add the feature, configurable selftest support, and docs. Why not ...? ============ - Why not /proc/[pid]/userfaultfd? Two main points (additional discussion [1]): - /proc/[pid]/* files are all owned by the user/group of the process, and they don't really support chmod/chown. So, without extending procfs it doesn't solve the problem this series is trying to solve. - The main argument *for* this was to support creating UFFDs for remote processes. But, that use case clearly calls for CAP_SYS_PTRACE, so to support this we could just use the UFFD syscall as-is. - Why not use a syscall? Access to syscalls is generally controlled by capabilities. We don't have a capability which is used for userfaultfd access without also granting more / other permissions as well, and adding a new capability was rejected [2]. - It's possible a LSM could be used to control access instead, but I have some concerns. I don't think this approach would be as easy to use, particularly if we were to try to solve this with something heavyweight like SELinux. Maybe we could pursue adding a new LSM specifically for this user case, but it may be too narrow of a case to justify that. Changelog ========= v4->v5: - Call userfaultfd_syscall_allowed() directly in the syscall, so we don't have to plumb a flag into new_userfaultfd(). [Nadav] - Refactored run_vmtests.sh to loop over UFFD test mods. [Nadav] - Reworded cover letter. - Picked up some Acked-by's. v3->v4: - Picked up an Acked-by on 5/5. - Updated cover letter to cover "why not ...". - Refactored userfaultfd_allowed() into userfaultfd_syscall_allowed(). [Peter] - Removed obsolete comment from a previous version. [Peter] - Refactored userfaultfd_open() in selftest. [Peter] - Reworded admin-guide documentation. [Mike, Peter] - Squashed 2 commits adding /dev/userfaultfd to selftest and making selftest configurable. [Peter] - Added "syscall" test modifier (the default behavior) to selftest. [Peter] v2->v3: - Rebased onto linux-next/akpm-base, in order to be based on top of the run_vmtests.sh refactor which was merged previously. - Picked up some Reviewed-by's. - Fixed ioctl definition (_IO instead of _IOWR), and stopped using compat_ptr_ioctl since it is unneeded for ioctls which don't take a pointer. - Removed the "handle_kernel_faults" bool, simplifying the code. The result is logically equivalent, but simpler. - Fixed userfaultfd selftest so it returns KSFT_SKIP appropriately. - Reworded documentation per Shuah's feedback on v2. - Improved example usage for userfaultfd selftest. v1->v2: - Add documentation update. - Test *both* userfaultfd(2) and /dev/userfaultfd via the selftest.

[net-next 0/6] net: support QUIC crypto

by Adel Abouchaev

QUIC requires end to end encryption of the data. The application usually prepares the data in clear text, encrypts and calls send() which implies multiple copies of the data before the packets hit the networking stack. Similar to kTLS, QUIC kernel offload of cryptography reduces the memory pressure by reducing the number of copies. The scope of kernel support is limited to the symmetric cryptography, leaving the handshake to the user space library. For QUIC in particular, the application packets that require symmetric cryptography are the 1RTT packets with short headers. Kernel will encrypt the application packets on transmission and decrypt on receive. This series implements Tx only, because in QUIC server applications Tx outweighs Rx by orders of magnitude. Supporting the combination of QUIC and GSO requires the application to correctly place the data and the kernel to correctly slice it. The encryption process appends an arbitrary number of bytes (tag) to the end of the message to authenticate it. The GSO value should include this overhead, the offload would then subtract the tag size to parse the input on Tx before chunking and encrypting it. With the kernel cryptography, the buffer copy operation is conjoined with the encryption operation. The memory bandwidth is reduced by 5-8%.

[PATCH] selftests/dma: Add a .gitignore file containing name of executable

by Gautam Menghani

The dma tests in kselftests are missing a .gitignore file, which leads to the dma_map_benchmark executable file showing up in "git status". This patch adds a .gitignore file containing the executable name.
