taskstats: fix struct taskstats breaks backward compatibility since version 15

2025-05-21T05:49:39Z

Problem ======== commit 658eb5ab916d ("delayacct: add delay max to record delay peak") - adding more fields commit f65c64f311ee ("delayacct: add delay min to record delay peak") - adding more fields commit b016d0873777 ("taskstats: modify taskstats version") - version bump to 15 Since version 15 (TASKSTATS_VERSION=15) the new layout of the structure adds fields in the middle of the structure, rendering all old software incompatible with newer kernels and software compiled against the new kernel headers incompatible with older kernels. Solution ========= move delay max and delay min to the end of taskstat, and bump the version to 16 after the change [wang.yaxin@zte.com.cn: adjust indentation] Link: https://lkml.kernel.org/r/202505192131489882NSciXV4EGd8zzjLuwoOK@zte.com.cn Link: https://lkml.kernel.org/r/20250510155413259V4JNRXxukdDgzsaL0Fo6a@zte.com.cn Fixes: f65c64f311ee ("delayacct: add delay min to record delay peak") Signed-off-by: Wang Yaxin Signed-off-by: xu xin Signed-off-by: Kun Jiang Reviewed-by: Yang Yang Cc: Balbir Singh Cc: Signed-off-by: Andrew Morton

bpf: Clarify handling of mark and tstamp by redirect_peer

2025-05-08T01:16:33Z

When switching network namespaces with the bpf_redirect_peer helper, the skb->mark and skb->tstamp fields are not zeroed out like they can be on a typical netns switch. This patch clarifies that in the helper description.

netlink: specs: ethtool: Remove UAPI duplication of phy-upstream enum

2025-04-28T22:49:47Z

The phy-upstream enum is already defined in the ethtool.h UAPI header and used by the ethtool userspace tool. However, the ethtool spec does not reference it, causing YNL to auto-generate a duplicate and redundant enum. Fix this by updating the spec to reference the existing UAPI enum in ethtool.h.

Pull io_uring fixes from Jens Axboe: - Correctly cap iov_iter->nr_segs for imports of registered buffers, both kbuf and normal ones. Three cleanups to make it saner first, then two fixes for each of the buffer types. This fixes a performance regression where partial buffer usage doesn't trim the tail number of segments, leading the block layer to iterate the IOs to check if it needs splitting. - Two patches tweaking the newly introduced zero-copy rx API, mostly to keep the API consistent once we add multiple interface queues per ring support in the 6.16 release. - zc rx unmapping fix for a dead device * tag 'io_uring-6.15-20250418' of git://git.kernel.dk/linux: io_uring/zcrx: fix late dma unmap for a dead dev io_uring/rsrc: ensure segments counts are correct on kbuf buffers io_uring/rsrc: send exact nr_segs for fixed buffer io_uring/rsrc: refactor io_import_fixed io_uring/rsrc: separate kbuf offset adjustments io_uring/rsrc: don't skip offset calculation io_uring/zcrx: add pp to ifq conversion helper io_uring/zcrx: return ifq id to the user
