--0000000000007e88f605fd5fa903 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hello Ganael, I didn't know that were a way to disabling aslr in a port! This is really nice. I'm having a lot of segfaults and tab crashing on firefox @aarch64 and mikael@ sugested turning it off to see if it fixes. I will test first with sysctl aslr off and if it works I will test port option. So syntax is: USES+=3D elfctl ELF_FEATURES=3D +noasr:<path_to_something>? Thanks, Ganael LAPLANCHE <martymac@freebsd.org> escreveu no dia segunda, 5/06/2023 =C3=A0(s) 11:20: > The branch main has been updated by martymac: > > URL: > https://cgit.FreeBSD.org/ports/commit/?id=3Df05f6dcedb5dad5b7b515ebede9bf= 6a58de1d46c > > commit f05f6dcedb5dad5b7b515ebede9bf6a58de1d46c > Author: Ganael LAPLANCHE <martymac@FreeBSD.org> > AuthorDate: 2023-06-05 10:18:04 +0000 > Commit: Ganael LAPLANCHE <martymac@FreeBSD.org> > CommitDate: 2023-06-05 10:18:04 +0000 > > comms/gqrx: Turn off ASLR > > Disable ASLR to work around the following crash: > > Program terminated with signal SIGSEGV, Segmentation fault. > Address not mapped to object. > --Type <RET> for more, q to quit, c to continue without paging-- > 0 0x000000082e9feecf in volk_32f_x2_dot_prod_32f_a_avx2_fma > (result=3D0x85185d7e0, input=3D0x906a9ab80, taps=3D0x8927eaa00, num_point= s=3D289) > at > /usr/ports/devel/volk/work/volk-2.5.1/kernels/volk/volk_32f_x2_dot_prod_3= 2f.h:833 > 833 dotProduct +=3D ((*aPtr++) * (*bPtr++)); > [Current thread is 1 (LWP 126875)] > (gdb) bt > 0 0x000000082e9feecf in volk_32f_x2_dot_prod_32f_a_avx2_fma > (result=3D0x85185d7e0, input=3D0x906a9ab80, taps=3D0x8927eaa00, num_point= s=3D289) > at > /usr/ports/devel/volk/work/volk-2.5.1/kernels/volk/volk_32f_x2_dot_prod_3= 2f.h:833 > 1 0x000000082e776b17 in __volk_32f_x2_dot_prod_32f_a > (result=3D0x85185d7e0, input=3D0x906a9ab80, taps=3D0x8927eaa00, num_point= s=3D289) > at /usr/ports/devel/volk/work/.build/lib/volk.c:5336 > 2 0x0000000825fe0b83 in gr::filter::kernel::fir_filter<float, float, > float>::filterN(float*, float const*, unsigned long) () from > /usr/local/lib/libgnuradio-filter.so.3.8.4 > --- > comms/gqrx/Makefile | 5 ++++- > 1 file changed, 4 insertions(+), 1 deletion(-) > > diff --git a/comms/gqrx/Makefile b/comms/gqrx/Makefile > index 927e049b2774..2974b7542287 100644 > --- a/comms/gqrx/Makefile > +++ b/comms/gqrx/Makefile > @@ -1,6 +1,7 @@ > PORTNAME=3D gqrx > PORTVERSION=3D 2.16 > DISTVERSIONPREFIX=3D v > +PORTREVISION=3D 1 > PORTEPOCH=3D 1 > CATEGORIES=3D comms hamradio > > @@ -31,7 +32,9 @@ LIB_DEPENDS=3D libgnuradio-runtime.so:comms/gnuradio \ > libjack.so:audio/jack \ > libportaudio.so:audio/portaudio > > -USES=3D cmake compiler:c++11-lang gl pkgconfig qt:5 > +USES=3D cmake compiler:c++11-lang elfctl gl pkgconfig qt:5 > + > +ELF_FEATURES=3D +noaslr:src/gqrx > > USE_GITHUB=3D yes > GH_ACCOUNT=3D gqrx-sdr > --=20 Nuno Teixeira FreeBSD Committer (ports) --0000000000007e88f605fd5fa903 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div>Hello Ganael,</div><div><br></div><div>I didn't k= now that were a way to disabling aslr in a port!
