[PATCH v3] selftests/capabilities: Fix possible file leak in copy_fromat_to

by Ma Ke

The open() function returns -1 on error. openat() and open() initialize 'from' and 'to', and only 'from' validated with 'if' statement. If the initialization of variable 'to' fails, we should better check the value of 'to' and close 'from' to avoid possible file leak. Improve the checking of 'from' additionally.

[PATCH net-next v7 00/10] net: openvswitch: Add sample multicasting.

by Adrian Moreno

** Background ** Currently, OVS supports several packet sampling mechanisms (sFlow, per-bridge IPFIX, per-flow IPFIX). These end up being translated into a userspace action that needs to be handled by ovs-vswitchd's handler threads only to be forwarded to some third party application that will somehow process the sample and provide observability on the datapath. A particularly interesting use-case is controller-driven per-flow IPFIX sampling where the OpenFlow controller can add metadata to samples (via two 32bit integers) and this metadata is then available to the sample-collecting system for correlation. ** Problem ** The fact that sampled traffic share netlink sockets and handler thread time with upcalls, apart from being a performance bottleneck in the sample extraction itself, can severely compromise the datapath, yielding this solution unfit for highly loaded production systems. Users are left with little options other than guessing what sampling rate will be OK for their traffic pattern and system load and dealing with the lost accuracy. Looking at available infrastructure, an obvious candidated would be to use psample. However, it's current state does not help with the use-case at stake because sampled packets do not contain user-defined metadata. ** Proposal ** This series is an attempt to fix this situation by extending the existing psample infrastructure to carry a variable length user-defined cookie. The main existing user of psample is tc's act_sample. It is also extended to forward the action's cookie to psample. Finally, a new OVS action (OVS_SAMPLE_ATTR_PSAMPLE) is created. It accepts a group and an optional cookie and uses psample to multicast the packet and the metadata. -- v6 -> v7: - Rebased - Fixed typo in comment. v5 -> v6: - Renamed emit_sample -> psample - Addressed unused variable and conditionally compilation of function. v4 -> v5: - Rebased. - Removed lefover enum value and wrapped some long lines in selftests. v3 -> v4: - Rebased. - Addressed Jakub's comment on private and unused nla attributes. v2 -> v3: - Addressed comments from Simon, Aaron and Ilya. - Dropped probability propagation in nested sample actions. - Dropped patch v2's 7/9 in favor of a userspace implementation and consume skb if emit_sample is the last action, same as we do with userspace. - Split ovs-dpctl.py features in independent patches. v1 -> v2: - Create a new action ("emit_sample") rather than reuse existing "sample" one. - Add probability semantics to psample's sampling rate. - Store sampling probability in skb's cb area and use it in emit_sample. - Test combining "emit_sample" with "trunc" - Drop group_id filtering and tracepoint in psample. rfc_v2 -> v1: - Accommodate Ilya's comments. - Split OVS's attribute in two attributes and simplify internal handling of psample arguments. - Extend psample and tc with a user-defined cookie. - Add a tracepoint to psample to facilitate troubleshooting. rfc_v1 -> rfc_v2: - Use psample instead of a new OVS-only multicast group. - Extend psample and tc with a user-defined cookie.

This crash is because a NULL pointer is passed to page_address() in sk_msg_recvmsg(). Due to the difference implementations depending on the architecture, page_address(NULL) will trigger a panic on Loongarch platform but not on X86 platform. So this bug was hidden on X86 platform for a while, but now it is exposed on Loongarch platform. The root cause is an empty skb (skb->len == 0) is put on the queue. This empty skb is a TCP FIN package, which is sent by shutdown(), invoked in test_sockmap_skb_verdict_shutdown(): shutdown(p1, SHUT_WR); In this case, in sk_psock_skb_ingress_enqueue(), num_sge is zero, and no page is put to this sge (see sg_set_page in sg_set_page), but this empty sge is queued into ingress_msg list. And in sk_msg_recvmsg(), this empty sge is used, and a NULL page is got by sg_page(sge). Pass this NULL-page to copy_page_to_iter(), it passed to kmap_local_page() and page_address(), then kernel panics. To solve this, we should skip the empty sge on the queue. So in sk_msg_recvmsg(), if msg_rx->sg.end is zero, that means it's an empty sge, skip it.

[PATCH v1 0/2] riscv: Expose orig_a0 to userspace for ptrace to set the actual a0

by zhouquan＠iscas.ac.cn

From: Quan Zhou <zhouquan(a)iscas.ac.cn> Due to the path that modifies a0 in syscall_enter_from_user_mode before the actual execution of syscall_handler [1], the kernel currently saves a0 to orig_a0 at the entry point of do_trap_ecall_u as an original copy of a0. Once the syscall is interrupted and later resumed, the restarted syscall will use orig_a0 to continue execution. The above rules generally apply except for ptrace(PTRACE_SETREGSET,), where the kernel will ignore the tracer's setting of tracee/a0 and will restart with the tracee/orig_a0. For the current kernel implementation of ptrace, projects like CRIU/Proot will encounter issues where the a0 setting becomes ineffective when performing ptrace(PTRACE_SETREGSET,). Here is a suggested solution, expose orig_a0 to userspace so that ptrace can choose whether to set orig_a0 based on the actual scenario. In fact, x86/orig_eax and loongArch/orig_a0 have adopted similar solutions.

[PATCH] selftests: tpm2: conform test to TAP output

by Muhammad Usama Anjum

The python unittest is being used for executing tests. TAP output cannot be added in the unittest framework. The python unittest is being run from a script. Add the output TAP logs to the script. Add "#" prefix to the python unittest output which will mark all output as informational TAP messages. Check exit status of the python unittest to decide if test passed or failed. Not sure why but python unittest outputs logs in stderr. So redirect the logs to stdout and then add prefix. Specify the bash explicitly instead of sh to run these tests as all of the kselftests are shifting towards using bash explicitly. Some interpreters have different syntax and cause issues.

[PATCH v2 0/4] Fix warnings in for-6.11/bpf

by Benjamin Tissoires

We had several complains in linux-next that there were warnings: CKI was not happy: it was the same situation than in an early report when HID-BPF was initially included: the automatically generated vmlinux.h doesn't contain all of the required structs and the compilation of the bpf program fails. We have multiple pointer to int cast complains and some docs that were not rendered properly. Include everything here. Signed-off-by: Benjamin Tissoires <bentiss(a)kernel.org> --- Changes in v2: - Also fix the pointer to int casts - Also fix the docs complains - Link to v1: https://lore.kernel.org/r/20240627-fix-cki-v1-1-2b47ceac116a@kernel.org --- Benjamin Tissoires (4): selftests/hid: ensure CKI can compile our new tests on old kernels HID: bpf: fix gcc warning and unify __u64 into u64 HID: bpf: doc fixes for hid_hw_request() hooks HID: bpf: doc fixes for hid_hw_request() hooks drivers/hid/bpf/hid_bpf_dispatch.c | 8 +++--- drivers/hid/bpf/hid_bpf_struct_ops.c | 2 +- drivers/hid/hid-core.c | 4 +-- drivers/hid/hidraw.c | 6 ++--- include/linux/hid_bpf.h | 31 +++++++++++++--------- .../testing/selftests/hid/progs/hid_bpf_helpers.h | 16 +++++++++++ 6 files changed, 44 insertions(+), 23 deletions(-) --- base-commit: d3e15189bfd4d0a9d3a7ad8bd0e6ebb1c0419f93 change-id: 20240627-fix-cki-f372855cbf6f Best regards, -- Benjamin Tissoires <bentiss(a)kernel.org>
