Subject: [PATCH] net/intel: fix use of non-recommended string functions
Date: Tue, 23 Jun 2026 12:22:21 +0100 [thread overview]
Message-ID: <20260623112221.677931-1-bruce.richardson@intel.com> (raw)
Replace use of the strncpy and strcpy functions with the safer strlcpy
alternative, which both bounds-checks and guarantees null termination.
In the process also replace instances of strcat with strlcat where
appropriate.
Fixes: 2d823ecd671c ("net/cpfl: support device initialization")
Fixes: c4c59ae62793 ("net/cpfl: refactor flow parser")
Fixes: c10881d3ee74 ("net/cpfl: support flow prog action")
Fixes: 9481b0902efe ("net/ice: send driver version to firmware")
Fixes: 7f7cbf80bdb7 ("net/ice: factorize firmware loading")
Fixes: 549343c25db8 ("net/idpf: support device initialization")
Fixes: 484f8e407a94 ("net/igb: support xstats by ID")
Fixes: fca82a8accf9 ("net/ixgbe: support xstats by ID")
Fixes: e163c18a15b0 ("net/i40e: update ptype and pctype info")
