Per https://github.com/rpm-software-management/rpm/commit/77d3529c31ca090a40b8d3959a0bcdd721a556d6 rpm 4.19.1+ will not consider actual filesystem permissions and ownership, and will quietly default to root if not expictly set otherwise in .spec file.
There's also additional diagnostics (printing what is in passwd/group) when user/group name lookup against the sysroot fails. That is never supposed to happen, and yet there was one report that it did: https://autobuilder.yoctoproject.org/typhoon/#/builders/44/builds/8493/steps/23/logs/stdio Investigating that issue led to the first three commits in this patchset: sysroot user management postinsts: run with /bin/sh -e to report errors when they happen classes/multilib: expand PACKAGE_WRITE_DEPS in addition to DEPENDS classes/staging: capture output of sysroot postinsts into logs Signed-off-by: Alexander Kanavin <a...@linutronix.de> --- meta/classes-global/package_rpm.bbclass | 34 ++++++++++++++++++++----- 1 file changed, 28 insertions(+), 6 deletions(-) diff --git a/meta/classes-global/package_rpm.bbclass b/meta/classes-global/package_rpm.bbclass index 2fc18fe98c1..a641dbdb299 100644 --- a/meta/classes-global/package_rpm.bbclass +++ b/meta/classes-global/package_rpm.bbclass @@ -103,6 +103,7 @@ def write_rpm_perfiledata(srcname, d): python write_specfile () { import oe.packagedata + import os,pwd,grp,stat # append information for logs and patches to %prep def add_prep(d, spec_files_bottom): @@ -198,6 +199,23 @@ python write_specfile () { # of the walk, the isdir() test would then fail and the walk code would assume its a file # hence we check for the names in files too. for rootpath, dirs, files in os.walk(walkpath): + def get_attr(path): + stat_f = os.stat(rootpath + "/" + path, follow_symlinks=False) + mode = stat.S_IMODE(stat_f.st_mode) + try: + owner = pwd.getpwuid(stat_f.st_uid).pw_name + except Exception as e: + bb.error("Content of /etc/passwd in sysroot:\n{}".format( + open(d.getVar("RECIPE_SYSROOT") +"/etc/passwd").read())) + raise e + try: + group = grp.getgrgid(stat_f.st_gid).gr_name + except Exception as e: + bb.error("Content of /etc/group in sysroot:\n{}".format( + open(d.getVar("RECIPE_SYSROOT") +"/etc/group").read())) + raise e + return "%attr({:o},{},{}) ".format(mode, owner, group) + path = rootpath.replace(walkpath, "") if path.endswith("DEBIAN") or path.endswith("CONTROL"): continue @@ -221,24 +239,28 @@ python write_specfile () { if dir == "CONTROL" or dir == "DEBIAN": continue dir = dir.replace("%", "%%%%%%%%") + p = path + '/' + dir # All packages own the directories their files are in... - target.append('%dir "' + path + '/' + dir + '"') + target.append(get_attr(dir) + '%dir "' + p + '"') else: # packages own only empty directories or explict directory. # This will prevent the overlapping of security permission. + attr = get_attr(path) if path and not files and not dirs: - target.append('%dir "' + path + '"') + target.append(attr + '%dir "' + path + '"') elif path and path in dirfiles: - target.append('%dir "' + path + '"') + target.append(attr + '%dir "' + path + '"') for file in files: if file == "CONTROL" or file == "DEBIAN": continue file = file.replace("%", "%%%%%%%%") - if conffiles.count(path + '/' + file): - target.append('%config "' + path + '/' + file + '"') + attr = get_attr(file) + p = path + '/' + file + if conffiles.count(p): + target.append(attr + '%config "' + p + '"') else: - target.append('"' + path + '/' + file + '"') + target.append(attr + '"' + p + '"') # Prevent the prerm/postrm scripts from being run during an upgrade def wrap_uninstall(scriptvar): -- 2.39.2
