[PATCH net-next 0/3] bonding: support aggregator selection based on port priority

by Hangbin Liu

This patchset introduces a new per-port bonding option: `ad_actor_port_prio`. It allows users to configure the actor's port priority, which can then be used by the bonding driver for aggregator selection based on port priority. This provides finer control over LACP aggregator choice, especially in setups with multiple eligible aggregators over 2 switches.

[PATCH v2] selftests/net: Ensure assert() triggers in psock_tpacket.c

by Wake Liu

The get_next_frame() function in psock_tpacket.c was missing a return statement in its default switch case, leading to a compiler warning. This was caused by a `bug_on(1)` call, which is defined as an `assert()`, being compiled out because NDEBUG is defined during the build. Instead of adding a `return NULL;` which would silently hide the error and could lead to crashes later, this change restores the original author's intent. By adding `#undef NDEBUG` before including <assert.h>, we ensure the assertion is active and will cause the test to abort if this unreachable code is ever executed.

[PATCH] selftests/net: Replace non-standard __WORDSIZE with sizeof(long) * 8

by Wake Liu

The `__WORDSIZE` macro, defined in the non-standard `<bits/wordsize.h>` header, is a GNU extension and not universally available with all toolchains, such as Clang when used with musl libc. This can lead to build failures in environments where this header is missing. The intention of the code is to determine the bit width of a C `long`. Replace the non-portable `__WORDSIZE` with the standard and portable `sizeof(long) * 8` expression to achieve the same result. This change also removes the inclusion of the now-unused `<bits/wordsize.h>` header.

[PATCH net] bonding: don't set oif to bond dev when getting NS target destination

by Hangbin Liu

Unlike IPv4, IPv6 routing strictly requires the source address to be valid on the outgoing interface. If the NS target is set to a remote VLAN interface, and the source address is also configured on a VLAN over a bond interface, setting the oif to the bond device will fail to retrieve the correct destination route. Fix this by not setting the oif to the bond device when retrieving the NS target destination. This allows the correct destination device (the VLAN interface) to be determined, so that bond_verify_device_path can return the proper VLAN tags for sending NS messages.

[PATCH v2 0/3] Better split_huge_page_test result check

by Zi Yan

This patchset uses kpageflags to get after-split folio orders for a better split_huge_page_test result check[1]. The added gather_folio_orders() scans through a VPN range and collects the numbers of folios at different orders. check_folio_orders() compares the result of gather_folio_orders() to a given list of numbers of different orders. This patchset also added new order and in folio offset to the split huge page debugfs's pr_debug()s; Changelog === From V1[2]: 1. Dropped split_huge_pages_pid() for loop step change to avoid messing up with PTE-mapped THP handling. split_huge_page_test.c is changed to perform split at [addr, addr + pagesize) range to limit one folio_split() per folio. 2. Moved pr_debug changes in Patch 2 to Patch 1. 3. Moved KPF_* to vm_util.h and used PAGEMAP_PFN instead of local PFN_MASK. 4. Used pagemap_get_pfn() helper. 5. Used char *vaddr and size_t len as inputs to gather_folio_orders() and check_folio_orders() instead of vpn and nr_pages. 6. Removed variable length variables and used malloc instead.
