Description of problem:

gyp fails to run in FIPS mode. It fails due to a call to hashlib.md5.


Version-Release number of selected component (if applicable):


How reproducible:

Very


Steps to Reproduce:

0. Acquire a RHEL 8 or CentOS 8 VM in FIPS mode
1. mkdir sandbox && cd sandbox && hg clone https://hg.mozilla.org/projects/nspr && hg clone https://hg.mozilla.org/projects/nss
2. cd nss
3. ./build.sh -v --enable-fips

Actual results:

[root@localhost nss]# ./build.sh -v
run_scanbuild gyp -f ninja --depth=/root/sandbox/nss --generator-output=. -Dtarget_arch=x64 -Denable_sslkeylogfile=1 -Dnss_dist_dir=/root/sandbox/dist -Dnss_dist_obj_dir=/root/sandbox/dist/Debug -Dnspr_include_dir=/root/sandbox/dist/Debug/include/nspr -Dnspr_lib_dir=/root/sandbox/dist/Debug/lib /root/sandbox/nss/nss.gyp

The above exception was the direct cause of the following exception:

  File "/usr/bin/gyp", line 11, in <module>
    load_entry_point('gyp==0.1', 'console_scripts', 'gyp')()

    return main(sys.argv[1:])

    return self._map_async(func, iterable, mapstar, chunksize).get()
  File "/usr/lib64/python3.6/multiprocessing/pool.py", line 644, in get
    raise self._value
ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for FIPS

Expected results:

gyp should build successfully in FIPS mode.

Additional info:

You should be able to pass the usedforsecurity=False flag to hashlib.md5(...) and hashlib.sha1(...) calls in generator/make.py and generator/ninja.py.
