[PATCH v1 bpf-next 0/8] selftests/bpf: Add sockaddr tests for kernel networking

by Jordan Rife

In a follow up to these patches, - commit 0bdf399342c5("net: Avoid address overwrite in kernel_connect") - commit 86a7e0b69bd5("net: prevent rewrite of msg_name in sock_sendmsg()") - commit c889a99a21bf("net: prevent address rewrite in kernel_bind()") - commit 01b2885d9415("net: Save and restore msg_namelen in sock_sendmsg") this patch series introduces BPF selftests that test the interaction between BPF sockaddr hooks and socket operations in kernel space. It focuses on regression test coverage to ensure that these operations do not overwrite their address parameter and also provides some sanity checks around kernel_getpeername() and kernel_getsockname(). It introduces two new components: a kernel module called sock_addr_testmod and a new test program called sock_addr_kern which is loosely modeled after and adapted from the old-style bpf/test_sock_addr.c selftest. When loaded, the kernel module will perform some socket operation in kernel space. The kernel module accepts five parameters controlling which socket operation will be performed and its inputs: MODULE_PARM_DESC(ip, "IPv4/IPv6/Unix address to use for socket operation"); MODULE_PARM_DESC(port, "Port number to use for socket operation"); MODULE_PARM_DESC(af, "Address family (AF_INET, AF_INET6, or AF_UNIX)"); MODULE_PARM_DESC(type, "Socket type (SOCK_STREAM or SOCK_DGRAM)"); MODULE_PARM_DESC(op, "Socket operation (BIND=0, CONNECT=1, SENDMSG=2)"); On module init, the socket operation is performed and results of are exposed through debugfs. - /sys/kernel/debug/sock_addr_testmod/success Indicates success or failure of the operation. - /sys/kernel/debug/sock_addr_testmod/addr The value of the address parameter after the operation. - /sys/kernel/debug/sock_addr_testmod/sock_name The value of kernel_getsockname() after the socket operation (if relevant). - /sys/kernel/debug/sock_addr_testmod/peer_name The value of kernel_getpeername(() after the socket operation (if relevant). The sock_addr_kern test program loads and unloads the kernel module to drive kernel socket operations, reads the results from debugfs, makes sure that the operation did not overwrite the address, and any result from kernel_getpeername() or kernel_getsockname() were as expected. == Patches == - Patch 1 introduces sock_addr_testmod and functions necessary for the test program to load and unload the module. - Patches 2-6 transform existing test helpers and introduce new test helpers to enable the sock_addr_kern test program. - Patch 7 implements the sock_addr_kern test program. - Patch 8 fixes the sock_addr bind test program to work for big endian architectures such as s390x.

[PATCH net 0/2] mptcp: fix fallback MIB counter and wrong var in selftests

by Matthieu Baerts (NGI0)

Here are two fixes related to MPTCP. The first patch fixes when the MPTcpExtMPCapableFallbackACK MIB counter is modified: it should only be incremented when a connection was using MPTCP options, but then a fallback to TCP has been done. This patch also checks the counter is not incremented by mistake during the connect selftests. This counter was wrongly incremented since its introduction in v5.7. The second patch fixes a wrong parsing of the 'dev' endpoint options in the selftests: the wrong variable was used. This option was not used before, but it is going to be soon. This issue is visible since v5.18.

[PATCH] Add test for more file systems in landlock - ext4

by Saasha Gupta

From 7bb9c34291b295e192155d2b800d2ef7ce910dfc Mon Sep 17 00:00:00 2001 From: Saasha Gupta <saashaa1122(a)gmail.com> Date: Mon, 1 Apr 2024 19:59:56 +0530 Subject: [PATCH] Add test for more file systems in landlock - ext4 Landlock LSM, a part of the security subsystem, has some tests in place for synthetic filesystems such as tmpfs, proc, sysfs, etc. The goal of the new issue, and hence this patch is to add tests for non synthetic file systems, such as ext4, btrfs, etc This patch adds tests for the ext4 file system.
