gcc: Fix CVE-2016-6131 in libiberty

2017-02-23T20:29:16+00:00

[NVD] -- https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-6131

The demangler in GNU Libiberty allows remote attackers to cause a denial
of service (infinite loop, stack overflow, and crash) via a cycle in the
references of remembered mangled types.

[BZ #71696] -- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71696

2016-08-04  Marcel Böhme  

	PR c++/71696
	* cplus-dem.c: Prevent infinite recursion when there is a cycle
	in the referencing of remembered mangled types.
	(work_stuff): New stack to keep track of the remembered mangled
	types that are currently being processed.
	(push_processed_type): New method to push currently processed
	remembered type onto the stack.
	(pop_processed_type): New method to pop currently processed
	remembered type from the stack.
	(work_stuff_copy_to_from): Copy values of new variables.
	(delete_non_B_K_work_stuff): Free stack memory.
	(demangle_args): Push/Pop currently processed remembered type.
	(do_type): Do not demangle a cyclic reference and push/pop
	referenced remembered type.

Fixes build on hardened PAX host with gcc-5 (linker error on relocs).
Completes no-PIE config by adding to ALL_* flags variables.
Borrowed from Gentoo gcc patches, tested on 2 hardened amd64 hosts.

gcc-cross: Avoid races with gcc_stash_builddir

2017-02-23T20:29:12+00:00

Its sad we need to do this but do_install and do_populate_sysroot appear
to change the files in ${B} and this breaks if something works in parallel
like gcc_stash_builddir. We've seen a few too many race errors on the
autobuilder which appear to be from this so make things run in sequence
deterministically for now.

An example failure was this from do_populate_sysroot whilst stash_builddir was running
in parallel:

classes: Drop now unneeded update_data calls

2017-02-15T17:29:41+00:00

Now that the datastore works dynamically we don't need the update_data calls
so we can just remove them. They're not actually done anything at all for
a while.

gcc-cross-initial: Remove unneeded temporary sysroot

2017-02-09T10:50:54+00:00

We used to need to build gcc-cross-initial against a bare sysroot to avoid
contamination. With RSS, we no longer need to do this since the recipe sysroot
is already bare. We can therefore simply point at that and drop this code.

gcc-6: Sync gcc stddef.h with musl stddef.h

2017-02-05T09:20:24+00:00

GCC provides some of std* headers including stddef.h
and it syncs with glibc definitions via __needed* defines
to find which datatypes are expected to be defined on top
of glibc. we need same for musl.

If we don't do this, things break with rm_work which removes things

gcc: Clean up unnecessary variable confusion

2017-01-26T10:41:09+00:00

SDKPKGSUFFIX could only really be "nativesdk" and TARGET_SYS never contains
that so the code manipulating TARGET_SYS is pointless. I suspect this once
worked against MULTIMACH_TARGET_SYS which would be a different question but
it no longer does. Its been cut and pasted everywhere.

This patch cleans up the variable references to make things a little more
readable.
