Subject: [PATCH RESEND 0/3] x86/vdso: Improve vdso=/vdso32= boot parameter validation
Date: Tue, 3 Nov 2026 15:58:49 +0100 [thread overview]
Message-ID: <20261103145848.427309-5-blum@kernel.org> (raw)
Replace the deprecated simple_strtoul() [1] with kstrtouint() when
parsing the vDSO boot parameters. This provides strict input validation,
rejects partial input, and warns when disabling vDSO for invalid values.
Adjust both warnings for consistency and update the documentation.
