[PATCH net-next 000/143] net: extend the netdev_features_t
by Jian Shen 18 Aug '21

18 Aug '21

For the prototype of netdev_features_t is u64, and the number of netdevice feature bits is 64 now. So there is no space to introduce new feature bit. This patchset try to solve it by change the prototype of netdev_features_t from u64 to bitmap. With this change, it's neccessary to introduce a set of bitmap operation helpers for netdev features. Meanwhile, the functions which use netdev_features_t as return value are also need to be changed, return the result as an output parameter. With above changes, it will affect hundreds of files, and all the nic drivers. To make it easy to be reviewed, split the changes to 124 patches to 6 parts. patch 1: code optimization for hns3 driver patch 2~23: convert the prototype which use netdev_features_t as return value patch 24: introduce fake helpers for bitmap operation patch 25~141: use netdev_feature_xxx helpers patch 142: use macro __DECLARE_NETDEV_FEATURE_MASK to replace netdev_feature_t declaration. patch 143: change the type of netdev_features_t to bitmap, and rewrite the bitmap helpers.

My good friend, I just want to know if you, can help me to transfer the amount of ($6Million). After the transfer we have to share it, 50% for me, and 50% for you. Please let me know if you can help me for more information in regards with the transfer. I hope you can work with me honestly? Thanks. Godwin Peter,

[PATCH net V2] page_pool: mask the page->signature before the checking
by Yunsheng Lin 09 Aug '21

09 Aug '21

As mentioned in commit c07aea3ef4d4 ("mm: add a signature in struct page"): "The page->signature field is aliased to page->lru.next and page->compound_head." And as the comment in page_is_pfmemalloc(): "lru.next has bit 1 set if the page is allocated from the pfmemalloc reserves. Callers may simply overwrite it if they do not need to preserve that information." The page->signature is OR’ed with PP_SIGNATURE when a page is allocated in page pool, see __page_pool_alloc_pages_slow(), and page->signature is checked directly with PP_SIGNATURE in page_pool_return_skb_page(), which might cause resoure leaking problem for a page from page pool if bit 1 of lru.next is set for a pfmemalloc page. What happens here is that the original pp->signature is OR'ed with PP_SIGNATURE after the allocation in order to preserve any existing bits(such as the bit 1, used to indicate a pfmemalloc page), so when those bits are present, those page is not considered to be from page pool and the DMA mapping of those pages will be left stale. As bit 0 is for page->compound_head, So mask both bit 0/1 before the checking in page_pool_return_skb_page(). And we will return those pfmemalloc pages back to the page allocator after cleaning up the DMA mapping.

[PATCH net-next] net: hns3: add support for triggering reset by ethtool
by Yufeng Mo 06 Aug '21

06 Aug '21

Currently, four reset types are supported for the HNS3 ethernet driver: IMP reset, global reset, function reset, and FLR. Only FLR can now be triggered by the user. To restore the device when an exception occurs, add support for triggering reset by ethtool. Run the "ethtool --reset DEVNAME mgmt | all | dedicated" to trigger the IMP | global | function reset manually. In addition, VF can only trigger function reset.
