From 42f8585ebb8fffad19a89314659ab9129176c3e9 Mon Sep 17 00:00:00 2001 From: Alexandru Avadanii Date: Sat, 1 Oct 2016 13:18:11 +0200 Subject: build: Rework patch mechanism for Fuel submodules While refactoring the patching mechanism, take care of: - Sync submodule handling with Fuel@OPFNV; - build: Investigate/prepare for moving patches to Fuel@OPNFV; - build: Investigate divergent fuel-mirror; - ISO build: cacheid for Fuel comps should not depend on Armband git commit; CHANGE: Rename/shuffle patches while grouping them in "features", preparing for upstreaming them to Fuel@OPNFV and beyond. CHANGE: Allow linking patches for better representing the dependency between one patch and different features. e.g. 0001-Add-arch-to-nailgun-release-and-target-image.patch: - part of `multiarch-fuel`, because it extends Fuel; - part of `direct-kernel-boot`, as arch is required for that; - part of `cross-bootstrap`, target image is arch-dependent; NOTE: Patch links are not staged to Fuel@OPNFV, they only serve as markers that a specific patch is part of a feature. CHANGE: Kill all Fuel component submodules, now handled in Fuel@OPNFV: - fuel-agent - fuel-astute - fuel-library - fuel-mirror - fuel-nailgun-agent - fuel-web CHANGE: Move armband-fuel-config.mk to armband git root. FIXME: m1.micro-Increase-profile-RAM-size-to-128MB.patch is NOT part of `cross-bootstrap` feature, but patch context says so ... FIXME: 0001-Add-arm64-deb-repositories-setup.patch is broken at `make patches-export` by removing spaces at EOL. v2 -> v3: * Phony patch support (links to show a patch belongs to a feature); * Updated README.md v3 -> v7: * Re-export Fuel submodules & plugins patches (update patch context); * Update Cavium mail addresses (s/caviumnetworks.com/cavium.com/); * Ignore submodule changes; * Add armband git repo info to gitinfo_fuel.txt at build time; Implements: ARMBAND-136 Closes-bug: ARMBAND-95 Closes-bug: ARMBAND-93 Closes-bug: ARMBAND-92 Change-Id: I1a236d9f43b2e6dca22055911f696b43c22b5973 Signed-off-by: Alexandru Avadanii --- .../0003-Fix-qemu-user-static-replacement.patch | 55 ++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 patches/fuel-agent/cross-bootstrap/0003-Fix-qemu-user-static-replacement.patch (limited to 'patches/fuel-agent/cross-bootstrap/0003-Fix-qemu-user-static-replacement.patch') diff --git a/patches/fuel-agent/cross-bootstrap/0003-Fix-qemu-user-static-replacement.patch b/patches/fuel-agent/cross-bootstrap/0003-Fix-qemu-user-static-replacement.patch new file mode 100644 index 00000000..3c849591 --- /dev/null +++ b/patches/fuel-agent/cross-bootstrap/0003-Fix-qemu-user-static-replacement.patch @@ -0,0 +1,55 @@ +From: Stanislaw Kardach +Date: Sun, 6 Mar 2016 16:09:39 +0100 +Subject: [PATCH] Fix qemu-user-static replacement + +--- + fuel_agent/manager.py | 6 ++++++ + fuel_agent/utils/build.py | 18 ++++++++++++++++++ + 2 files changed, 24 insertions(+) + +diff --git a/fuel_agent/manager.py b/fuel_agent/manager.py +index ba1ab78..637c99a 100644 +--- a/fuel_agent/manager.py ++++ b/fuel_agent/manager.py +@@ -760,6 +760,12 @@ class Manager(object): + fu.mount_bind(chroot, '/proc') + bu.populate_basic_dev(chroot) + ++ # we need to make sure that qemu-{target_arch}-static binary is ++ # not replaced inside chroot because we're possibly using it ++ # through qemu-debootstrap ++ LOG.debug('Preventing qemu-user-static replacement inside chroot') ++ bu.prevent_qemu_replacement(chroot, CONF.target_arch) ++ + def destroy_chroot(self, chroot): + # Umount chroot tree and remove images tmp files + if not bu.stop_chrooted_processes(chroot, signal=signal.SIGTERM): +diff --git a/fuel_agent/utils/build.py b/fuel_agent/utils/build.py +index 74cbfd8..1bc0a5f 100644 +--- a/fuel_agent/utils/build.py ++++ b/fuel_agent/utils/build.py +@@ -320,6 +320,24 @@ def populate_basic_dev(chroot): + utils.execute('chroot', chroot, + 'ln', '-s', '/proc/self/fd', '/dev/fd') + ++def prevent_qemu_replacement(chroot, arch): ++ """Prevents qemu-user-static replacement inside chroot. ++ ++ Use dpkg-divert to prevent replacing qemu-user-static binary inside ++ chroot which is necessary for host-side qemu-debootstrap to work ++ properly.""" ++ if arch == 'arm64': ++ qemu = 'qemu-aarch64-static' ++ elif arch == 'amd64': ++ qemu = 'qemu-x86_64-static' ++ utils.execute('chroot', chroot, ++ 'dpkg-divert', '--divert', '/usr/bin/%s.orig' % qemu, ++ '/usr/bin/%s' % qemu) ++ utils.execute('chroot', chroot, ++ 'dpkg-divert', '--divert', '/usr/sbin/update-binfmts.orig', ++ '--rename', '/usr/sbin/update-binfmts') ++ utils.execute('chroot', chroot, 'ln', '-sf', '/bin/true', ++ '/usr/sbin/update-binfmts') + + def create_sparse_tmp_file(dir, suffix, size=8192): + """Creates sparse file. -- cgit 1.2.3-korg
