Subject: Re: 2.6.24-rc3: find complains about /proc/net
Date: Tue, 20 Nov 2007 14:54:57 -0800 (PST) [thread overview]
Message-ID: <20071120225457.B6E2D26F8BE@magilla.localdomain> (raw)
In-Reply-To: Ingo Molnar's message of Tuesday, 20 November 2007 23:35:59 +0100 <20071120223559.GA6655@elte.hu>
When did /proc/self get changed to follow tgid instead of pid? glibc uses
/proc/self to refer to various things that are usually shared anyway (fd,
maps, cwd, exe), but I think the expectation has always been that this
refers to the same calling thread, not the group leader. e.g., if one
thread has changed uids so it no longer has access to the group leader's
/proc/PID/fd, suddenly it using /proc/self/fd starts failing.
Thanks,
Roland
