Subject: [PULL 30/30] linux-user: Implement capability prctls
Date: Tue, 11 Jan 2022 20:52:47 +0100	[thread overview]
Message-ID: <20220111195247.1737641-31-laurent@vivier.eu> (raw)
In-Reply-To: <20220111195247.1737641-1-laurent@vivier.eu>

From: Richard Henderson <richard.henderson@linaro.org>

This is PR_CAPBSET_READ, PR_CAPBSET_DROP and the "legacy"
PR_CAP_AMBIENT PR_GET_SECUREBITS, PR_SET_SECUREBITS.

All of these arguments are integer values only, and do not
require mapping of values between host and guest.
