Retain error value in struct devlink_fmsg, to relieve drivers from checking it after each call. Note that fmsg is an in-memory builder/buffer of formatted message, so it's not the case that half baked message was sent somewhere. We could find following scheme in multiple drivers: err = devlink_fmsg_obj_nest_start(fmsg); if (err) return err; err = devlink_fmsg_string_pair_put(fmsg, "src", src); if (err) return err; err = devlink_fmsg_something(fmsg, foo, bar); if (err) return err; // and so on... err = devlink_fmsg_obj_nest_end(fmsg); With retaining error API that translates to: devlink_fmsg_obj_nest_start(fmsg); devlink_fmsg_string_pair_put(fmsg, "src", src); devlink_fmsg_something(fmsg, foo, bar); // and so on... devlink_fmsg_obj_nest_end(fmsg); What means we check error just when is time to send. Possible error scenarios are developer error (API misuse) and memory exhaustion, both cases are good candidates to choose readability over fastest possible exit. Note that this patch keeps returning errors, to allow per-driver conversion to the new API, but those are not needed at this point already. This commit itself is an illustration of benefits for the dev-user, more of it will be in separate commits of the series. Reviewed-by:

Extend the support to full range of min/max checks. None of the existing YNL families required complex integer validation. The support is less than trivial, because we try to keep struct nla_policy tiny the min/max members it holds in place are s16. Meaning we can only express checks in range of s16. For larger ranges we need to define a structure and link it in the policy. Link: https://lore.kernel.org/r/20231018163917.2514503-3-kuba@kernel.orgSigned-off-by:

This reverts commit 108a36d0. 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 66991703 ("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. Reported-by:

When closing the first subflow, the MPTCP protocol unconditionally calls tcp_disconnect(), which in turn generates a reset if the subflow is established. That is unexpected and different from what MPTCP does with MPJ subflows, where resets are generated only on FASTCLOSE and other edge scenarios. We can't reuse for the first subflow the same code in place for MPJ subflows, as MPTCP clean them up completely via a tcp_close() call, while must keep the first subflow socket alive for later re-usage, due to implementation constraints. This patch adds a new helper __mptcp_subflow_disconnect() that encapsulates, a logic similar to tcp_close, issuing a reset only when the MPTCP_CF_FASTCLOSE flag is set, and performing a clean shutdown otherwise.

The MPTCP protocol can acquire the subflow-level socket lock and cause the tcp backlog usage. When inserting new skbs into the backlog, the stack will try to coalesce them. Currently, we have no check in place to ensure that such coalescing will respect the MPTCP-level DSS, and that may cause data stream corruption, as reported by Christoph. Address the issue by adding the relevant admission check for coalescing in tcp_add_backlog(). Note the issue is not easy to reproduce, as the MPTCP protocol tries hard to avoid acquiring the subflow-level socket lock.
