From 7c6513082b787a7d36ab7d75720b48f8a216089c Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Wed, 13 Mar 2019 10:45:35 +0100 Subject: Fix output of LD_SHOW_AUXV=1. Starting with commit 1616d034b61622836d3a36af53dcfca7624c844e the output was corrupted on some platforms as _dl_procinfo was called for every auxv entry and on some architectures like s390 all entries were represented as "AT_HWCAP". This patch is removing the condition and let _dl_procinfo decide if an entry is printed in a platform specific or generic way. This patch also adjusts all _dl_procinfo implementations which assumed that they are only called for AT_HWCAP or AT_HWCAP2. They are now just returning a non-zero-value for entries which are not handled platform specifc. ChangeLog: * elf/dl-sysdep.c (_dl_show_auxv): Remove condition and always call _dl_procinfo. * sysdeps/unix/sysv/linux/s390/dl-procinfo.h (_dl_procinfo): Ignore types other than AT_HWCAP. * sysdeps/sparc/dl-procinfo.h (_dl_procinfo): Likewise. * sysdeps/unix/sysv/linux/i386/dl-procinfo.h (_dl_procinfo): Likewise. * sysdeps/powerpc/dl-procinfo.h (_dl_procinfo): Adjust comment in the case of falling back to generic output mechanism. * sysdeps/unix/sysv/linux/arm/dl-procinfo.h (_dl_procinfo): Likewise. --- ChangeLog | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index 14d0872..50acb42 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,17 @@ +2019-03-13 Stefan Liebler + + * elf/dl-sysdep.c (_dl_show_auxv): Remove condition and always + call _dl_procinfo. + * sysdeps/unix/sysv/linux/s390/dl-procinfo.h (_dl_procinfo): + Ignore types other than AT_HWCAP. + * sysdeps/sparc/dl-procinfo.h (_dl_procinfo): Likewise. + * sysdeps/unix/sysv/linux/i386/dl-procinfo.h (_dl_procinfo): + Likewise. + * sysdeps/powerpc/dl-procinfo.h (_dl_procinfo): Adjust comment + in the case of falling back to generic output mechanism. + * sysdeps/unix/sysv/linux/arm/dl-procinfo.h (_dl_procinfo): + Likewise. + 2019-03-12 Florian Weimer * elf/elf.h (DF_1_KMOD, DF_1_WEAKFILTER, DF_1_NOCOMMON): Define. -- cgit v1.1
