  "message": "ethtool: tsinfo: fix uninitialized stats on the by-PHC path\n\ntsinfo_prepare_data() has two code paths: a \"by-PHC\" path for\nuser-specified hardware timestamping providers, and the old path.\nCommit 89e281ebff72 (\"ethtool: init tsinfo stats if requested\") added\nethtool_stats_init() to mark stat slots as ETHTOOL_STAT_NOT_SET before\nthe driver callback populates them, but placed the call inside the\nold-path block.\n\nWhen commit b9e3f7dc9ed9 (\"net: ethtool: tsinfo: Enhance tsinfo to\nsupport several hwtstamp by net topology\") added the by-PHC early\nreturn, it landed above the stats initialization. On that path\nthe stats array retains the zero-fill from ethnl_init_reply_data()\u0027s\nzalloc. This leads to the reply including a stats nest with four\nzero-valued attributes that should have been absent.\n\nReject GET requests for stats with HWTSTAMP_PROVIDER or dump.\n\nFixes: b9e3f7dc9ed9 (\"net: ethtool: tsinfo: Enhance tsinfo to support several hwtstamp by net topology\")\nReviewed-by: Maxime Chevallier \u003cmaxime.chevallier@bootlin.com\u003e\nLink: https://patch.msgid.link/20260526153533.2779187-7-kuba@kernel.org\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\n",
