[PATCH net] Revert "ethtool: Fix mod state of verbose no_mask bitset"

by Kory Maincent

This reverts commit 108a36d07c01edbc5942d27c92494d1c6e4d45a0. It was reported that this fix breaks the possibility to remove existing WoL flags. For example: ~$ ethtool lan2 ... Supports Wake-on: pg Wake-on: d ... ~$ ethtool -s lan2 wol gp ~$ ethtool lan2 ... Wake-on: pg ... ~$ ethtool -s lan2 wol d ~$ ethtool lan2 ... Wake-on: pg ... This worked correctly before this commit because we were always updating a zero bitmap (since commit 6699170376ab ("ethtool: fix application of verbose no_mask bitset"), that is) so that the rest was left zero naturally. But now the 1->0 change (old_val is true, bit not present in netlink nest) no longer works.

[PATCH net 0/5] mptcp: Fixes for v6.6

by Mat Martineau

Patch 1 corrects the logic for MP_JOIN tests where 0 RSTs are expected. Patch 2 ensures MPTCP packets are not incorrectly coalesced in the TCP backlog queue. Patch 3 avoids a zero-window probe and associated WARN_ON_ONCE() in an expected MPTCP reinjection scenario. Patches 4 & 5 allow an initial MPTCP subflow to be closed cleanly instead of always sending RST. Associated selftest is updated.

[PATCH] rust: docs: fix logo replacement

by Miguel Ojeda

The static files placement by `rustdoc` changed in Rust 1.67.0 [1], but the custom code we have to replace the logo in the generated HTML files did not get updated. Thus update it to have the Linux logo again in the output. Hopefully `rustdoc` will eventually support a custom logo from a local file [2], so that we do not need to maintain this hack on our side.

[PATCH 6/6] rcu/tree: Defer setting of jiffies during stall reset

by Frederic Weisbecker

From: "Joel Fernandes (Google)" <joel(a)joelfernandes.org> There are instances where rcu_cpu_stall_reset() is called when jiffies did not get a chance to update for a long time. Before jiffies is updated, the CPU stall detector can go off triggering false-positives where a just-started grace period appears to be ages old. In the past, we disabled stall detection in rcu_cpu_stall_reset() however this got changed [1]. This is resulting in false-positives in KGDB usecase [2]. Fix this by deferring the update of jiffies to the third run of the FQS loop. This is more robust, as, even if rcu_cpu_stall_reset() is called just before jiffies is read, we would end up pushing out the jiffies read by 3 more FQS loops. Meanwhile the CPU stall detection will be delayed and we will not get any false positives.
