[PATCH net-next 2/4] selftests: forwarding: lib: Move require_command to net, generalize

by Petr Machata

This helper could be useful to more than just forwarding tests. Move it upstairs and port over to log_test_skip(). Split the function into two parts: the bit that actually checks and reports skip, which is in a new function check_command(). And a bit that exits the test script if the check fails. This allows users consistent checking behavior while giving an option to bail out from a single test without bailing out of the whole script.

[PATCH v6 0/7] Buddy allocator like (or non-uniform) folio split

by Zi Yan

Hi all, This patchset adds a new buddy allocator like (or non-uniform) large folio split to reduce the total number of after-split folios, the amount of memory needed for multi-index xarray split, and keep more large folios after a split. It is on top of mm-everything-2025-02-01-05-58. It is ready to be merged. Instead of duplicating existing split_huge_page*() code, __folio_split() is introduced as the shared backend code for both split_huge_page_to_list_to_order() and folio_split(). __folio_split() can support both uniform split and buddy allocator like (or non-uniform) split. All existing split_huge_page*() users can be gradually converted to use folio_split() if possible. In this patchset, I converted truncate_inode_partial_folio() to use folio_split(). xfstests quick group passed for both tmpfs and xfs. Changelog === From V5[7]: 1. Split shmem to any lower order patches are in mm tree, so dropped from this series. 2. Rename split_folio_at() to try_folio_split() to clarify that non-uniform split will not be used if it is not supported. From V4[6]: 1. Enabled shmem support in both uniform and buddy allocator like split and added selftests for it. 2. Added functions to check if uniform split and buddy allocator like split are supported for the given folio and order. 3. Made truncate fall back to uniform split if buddy allocator split is not supported (CONFIG_READ_ONLY_THP_FOR_FS and FS without large folio). 4. Added the missing folio_clear_has_hwpoisoned() to __split_unmapped_folio(). From V3[5]: 1. Used xas_split_alloc(GFP_NOWAIT) instead of xas_nomem(), since extra operations inside xas_split_alloc() are needed for correctness. 2. Enabled folio_split() for shmem and no issue was found with xfstests quick test group. 3. Split both ends of a truncate range in truncate_inode_partial_folio() to avoid wasting memory in shmem truncate (per David Hildenbrand). 4. Removed page_in_folio_offset() since page_folio() does the same thing. 5. Finished truncate related tests from xfstests quick test group on XFS and tmpfs without issues. 6. Disabled buddy allocator like split on CONFIG_READ_ONLY_THP_FOR_FS and FS without large folio. This check was missed in the prior versions. From V2[3]: 1. Incorporated all the feedback from Kirill[4]. 2. Used GFP_NOWAIT for xas_nomem(). 3. Tested the code path when xas_nomem() fails. 4. Added selftests for folio_split(). 5. Fixed no THP config build error. From V1[2]: 1. Split the original patch 1 into multiple ones for easy review (per Kirill). 2. Added xas_destroy() to avoid memory leak. 3. Fixed nr_dropped not used error (per kernel test robot). 4. Added proper error handling when xas_nomem() fails to allocate memory for xas_split() during buddy allocator like split. From RFC[1]: 1. Merged backend code of split_huge_page_to_list_to_order() and folio_split(). The same code is used for both uniform split and buddy allocator like split. 2. Use xas_nomem() instead of xas_split_alloc() for folio_split(). 3. folio_split() now leaves the first after-split folio unlocked, instead of the one containing the given page, since the caller of truncate_inode_partial_folio() locks and unlocks the first folio. 4. Extended split_huge_page debugfs to use folio_split(). 5. Added truncate_inode_partial_folio() as first user of folio_split(). Design === folio_split() splits a large folio in the same way as buddy allocator splits a large free page for allocation. The purpose is to minimize the number of folios after the split. For example, if user wants to free the 3rd subpage in a order-9 folio, folio_split() will split the order-9 folio as: O-0, O-0, O-0, O-0, O-2, O-3, O-4, O-5, O-6, O-7, O-8 if it is anon O-1, O-0, O-0, O-2, O-3, O-4, O-5, O-6, O-7, O-9 if it is pagecache Since anon folio does not support order-1 yet. The split process is similar to existing approach: 1. Unmap all page mappings (split PMD mappings if exist); 2. Split meta data like memcg, page owner, page alloc tag; 3. Copy meta data in struct folio to sub pages, but instead of spliting the whole folio into multiple smaller ones with the same order in a shot, this approach splits the folio iteratively. Taking the example above, this approach first splits the original order-9 into two order-8, then splits left part of order-8 to two order-7 and so on; 4. Post-process split folios, like write mapping->i_pages for pagecache, adjust folio refcounts, add split folios to corresponding list; 5. Remap split folios 6. Unlock split folios. __split_unmapped_folio() and __split_folio_to_order() replace __split_huge_page() and __split_huge_page_tail() respectively. __split_unmapped_folio() uses different approaches to perform uniform split and buddy allocator like split: 1. uniform split: one single call to __split_folio_to_order() is used to uniformly split the given folio. All resulting folios are put back to the list after split. The folio containing the given page is left to caller to unlock and others are unlocked. 2. buddy allocator like (or non-uniform) split: (old_order - new_order) calls to __split_folio_to_order() are used to split the given folio at order N to order N-1. After each call, the target folio is changed to the one containing the page, which is given as a folio_split() parameter. After each call, folios not containing the page are put back to the list. The folio containing the page is put back to the list when its order is new_order. All folios are unlocked except the first folio, which is left to caller to unlock. Patch Overview === 1. Patch 1 added __split_unmapped_folio() and __split_folio_to_order() to prepare for moving to new backend split code. 2. Patch 2 moved common code in split_huge_page_to_list_to_order() to __folio_split(). 3. Patch 3 added new folio_split() and made split_huge_page_to_list_to_order() share the new __split_unmapped_folio() with folio_split(). 4. Patch 4 removed no longer used __split_huge_page() and __split_huge_page_tail(). 5. Patch 5 added a new in_folio_offset to split_huge_page debugfs for folio_split() test. 6. Patch 6 used try_folio_split() for truncate operation. 7. Patch 7 added folio_split() tests. Any comments and/or suggestions are welcome. Thanks.

[PATCH net-next v18 00/25] Introducing OpenVPN Data Channel Offload

by Antonio Quartulli

Notable changes since v17: * fixed netdevice_tracker pointer assignment in netlink post_doit (triggered by kernel test robot on m86k) * renamed nla_get_uint() to ovpn_nla_get_uint() in ovpn-cli.c to avoid clashes with libnl-3.11.0 FTR, here are the notable changes since v16: * fixed usage of netdev tracker by removing dev_tracker member from ovpn_priv and adding it to ovpn_peer and ovpn_socket as those are the objects really holding a ref to the netdev * switched ovpn_get_dev_from_attrs() to GFP_ATOMIC to prevent sleep under rcu_read_lock * allocated netdevice_tracker in ovpn_nl_pre_doit() [stored in user_ptr[1]] to keep track of the netdev reference held during netlink handler calls * moved whole socket detaching routine to worker. This way the code is allowed to sleep and in turn it can be executed under lock_sock. This lock allows us to happily coordinate concurrent attach/detach calls. (note: lock is acquired everytime the refcnt for the socket is decremented, because this guarantees us that setting the refcnt to 0 and detaching the socket will happen atomically) * dropped kref_put_sock()/refcount handler as it's not required anymore, thanks to the point above * re-arranged ovpn_socket_new() in order to simplify error path by first allocating the new ovpn_sock and then attaching Please note that some patches were already reviewed/tested by a few people. iThese patches have retained the tags as they have hardly been touched.

[PATCH v3 0/2] scanf: convert self-test to KUnit

by Tamir Duberstein

This is one of just 3 remaining "Test Module" kselftests (the others being bitmap and printf), the rest having been converted to KUnit. In addition to the enclosed patch, please consider this an RFC on the removal of the "Test Module" kselftest machinery. I tested this using: $ tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 scanf Signed-off-by: Tamir Duberstein <tamird(a)gmail.com> --- Changes in v3: - Reduce diff noise in lib/Makefile.
