Subject: Re: [PATCH v2] fs: introduce pipe-only dump mode suid_dumpable=3
Date: Fri, 22 Jun 2012 12:56:19 +0100 [thread overview]
Message-ID: <20120622125619.28b36311@bob.linux.org.uk> (raw)
In-Reply-To: <20120622000049.GA7877@www.outflux.net>
> This patch introduces suid_dumpable=3 to allow privilege-changed
> processes to be dumped only to a pipe handler (and not directly to
> disk). The value of suid_dumpable=2 is now deprecated, and attempting
> to set this sysctl value returns -EINVAL.
