Subject: Re: [PATCH][RFC] pseudo: intercept syscall() and return ENOTSUP for renameat2

Message-ID: <1522501975.11431.208.camel@linuxfoundation.org> (raw)
In-Reply-To: <20180331000631.5f050451@seebsdell>
Just to report back, I've tried testing an earlier version of pseudo
master with the path changes reverted and current master. With both I'm
seeing librsvg fail during do_install with a segfault (you have to
remove the 2> /dev/null to see it).
I'm seeing multiple entries in the host's dmesg:
[180364.269879] glib-compile-re[38258]: segfault at 0 ip (null) sp 00007ffffaafbf78 error 14 in glib-compile-resources[55abc201b000+9000]

I believe that libglib-2.0 does use syscall() for something and that
the above programs are calling into it and faulting.
Its likely possible to reproduce this outside of a build by running
make install from librsvg under pseudo.
If I take master and revert 778abd3686fb7c419e9016fdd9e93819405d52aa fr
om pseudo, it no longer segfaults.
So something is not working correctly with the intercept sadly.
Cheers,
Richard
