rpmbuild skip "checking for unpackaged file(s) /usr/lib/rpm/check-files"

While building kernel rpm packagerpmbuild does it's slow "Checking for unpackaged file(s)" check:

$ make -j$(nproc) binrpm-pkg
...
Checking for unpackaged file(s): /usr/lib/rpm/check-files /home/user/rpmbuild/BUI
LDROOT/kernel-4.17.0_rc5_next_20180517_3.gd86d9e8_default+-98.x86_64

For kernel even on powerful machine it takes 30 mins. How to avoid that? I've tried to to avoid it with _unpackaged_files_terminate_build, but it didn't help:

echo "%_unpackaged_files_terminate_build    0" >> ~/.rpmmacros

Also adding --nocheck to rpmbuild call to binrpm-pkg target in scripts/package/Makefile didn't help.

But maybe it's something else wrong. When I build with configuration make allyesconfig rpm file has 168MB. RPM file builded with openSUSE Tumbleweed config has 647MB.

For future reference, the problem line is in buildHost(void) inside build RPM.

Code:

    bhMacro = rpmExpand("%{?_buildhost}", NULL);
    if (strcmp(bhMacro, "") != 0) {
        rasprintf(&hostname, "%s", bhMacro);
    } else {
    hostname = rcalloc(NI_MAXHOST + 1, sizeof(*hostname));
    if (gethostname(hostname, NI_MAXHOST) == 0) {
        struct addrinfo *ai, hints;
        memset(&hints, 0, sizeof(hints));
        hints.ai_flags = AI_CANONNAME;

        if (getaddrinfo(hostname, NULL, &hints, &ai) == 0) {
        strcpy(hostname, ai->ai_canonname);
        freeaddrinfo(ai);
        } else {
        rpmlog(RPMLOG_WARNING,
                    _("Could not canonicalize hostname: %s\n"), hostname);
        }
    }

If you define _buildhost with hostname, it will skip the DNS call.

Example:

rpmbuild -bb --define "_buildhost $(hostname)" ./path/to/spec/file.spec

Note: the install will still hang on the "check files" part, but it's doing other stuff in the background, and the DNS call itself will be skipped.

Got same issue and found out what was happening.

If your rpmbuild is slow to process it doesn't come from /usr/lib/rpm/check-files script:
try to comment all its lines, you'll see that it's still hanging after that, even if this script is basically doing nothing anymore.

Executing :

strace -f -s900 rpmbuild [your args]

You'll see that between hangs, DNS calls are issued (calls to /usr/lib64/libresolv.so library) trying to resolve the hostname of your build machine, which fall on timeout after some time and then retries .

If your machine have a faulty DNS configuration or if your DNS server is not working, the rpmbuild process will hang on each launch.

To avoid those hangs:

  • correct your DNS configuration on your build machine, or
  • sudo rm -f /etc/resolv.conf on your build machine

The real question remaining is: Why a local process like rpmbuild is doing DNS calls?

Unfortunately, I'm pretty sure you cannot stop it. Is it on a slow drive? Are you in an enterprise environment where /home/user is network-mounted?

What you tried to change simply says "if you find files that I didn't account for, make it a warning not an error."
