Source: linux
Version: 6.4.11-1
Severity: normal
Hi,
starting with dpkg 1.22.0, linux fails to cross-build with build=amd64 and
host=arm64 like this:
# HOSTCC scripts/basic/fixdep
gcc -Wp,-MMD,scripts/basic/.fixdep.d -g -O2
-ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong
-fstack-clash-protection -Wformat -Werror=format-security
-mbranch-protection=standard -Wdate-time -D_FORTIFY_SOURCE=2 -I
./scripts/basic -Wl,-z,relro -o scripts/basic/fixdep
/<<PKGBUILDDIR>>/scripts/basic/fixdep.c
gcc: error: unrecognized command-line option '-mbranch-protection=standard'
This is because starting with dpkg 1.22.0, CFLAGS includes architecture
specific flags (in this case branch-protection=standard) which will not work on
amd64 (the above is a native gcc as part of a cross-build). So we are now able
to easily find a new class of bugs that was hidden before where flags meant for
the host architecture are passed to the build architecture compiler and
vice-versa. In the future, dpkg will fix this by setting flags like
CFLAGS_FOR_BUILD which should be used for native gcc invocations. Until then,
these variables can be set manually. Setting these manually is only a crutch
because they get side-effects from DEB_<flags>_MAINT_<op> DEB_<flags>_<op> and
thus the following patch uses ?= to not override the variables as set by dpkg:

cc1: error: ‘-fcf-protection=full’ is not supported for this target
The flag cf-protection=full is amd64 specific but the above is a cross-build
for arm64 and thus it errors out again. So there is host-arch flags leaking
into a native-arch build (first problem) as well as build-arch flags leaking
into a foreign-arch build (second problem).
I had a look into debian/rules.d/tools/objtool/Makefile which seems to be
setting the flags for this but wasn't able to figure out a fitting solution but
maybe what is done with REALHOSTCC and REALHOSTLD has to be done with to CFLAGS
as well like REALHOSTCFLAGS? I need some advice here.
Also, could you turn the "mkdir $*" into "mkdir -p $*" in the rule for
objtool.real-% please? That would make it possible to do re-builds without
cleaning first and my machine is super slow, thanks! :)
An ugly workaround that fixes both issues is to use the following in
debian/rules.real:
MAKE_CLEAN = $(setup_env) $(MAKE) KCFLAGS=-fdebug-prefix-map=$(CURDIR)/=
KBUILD_HOSTCFLAGS='' HOSTCFLAGS='' KBUILD_HOSTLDFLAGS=''
What do you think?
Thanks!
cheers, josch
