OPENSSL_CONF="" is treated differently to no OPENSSL_CONF in
the environment by OpenSSL. OPENSSL_CONF="" lead to crypto
failure being reported in FIPS mode.
There are times where you want named-checkconf to check whether the
dnssec-policies should be constrained by the cryptographic algorithms
supported by the operation system or to just accept all possible
algorithms. This provides a mechanism to make that selection.
Call dst_lib_init to set FIPS mode if it was turned on at configure
time.
Check that named-checkconf report that dnssec policies that wont
work in FIPS mode are reported if named would be running in FIPS
mode.
Diffie-Hellman key echange doesn't appear to work in FIPS mode for
OpenSSL 1.x.x. Add feature test (--have-fips-dh) to identify builds
where DH key exchanges work (non FIPS builds and OpenSSL 3.0.0+) and
exclude test that would otherwise fail.
This provides more detail about which instance of specific OpenSSL
calls that have failed by reporting the file name and line numbers
involved when dst__openssl_toresult2 and dst__openssl_toresult3 are
called.
- RSASHA1 (5) and NSEC3RSASHA1 (7) are not accepted in FIPS mode
- minimum RSA key size is set to 2048 bit
adjust kasp and checkconf system tests to ensure non FIPS
compliant configurations are not used in FIPS mode
With FIPS mode enabled 'isc_hmac_init_test' and 'isc_hmac_md5_test'
tests of hmac_test and 'isc_md_init_test' and 'isc_md_md5_test' test
of md_test fail.
This is due to leveraging MD5, which is disabled in FIPS mode.
The CI doesn't provide useful forensics when a system test locks
up. Fork the process and kill it with ABRT if it is still running
after 20 minutes. Pass the exit status to the caller.
The `isc_trampoline` module had a lot of machinery to support stable
thread IDs for use by hazard pointers. But the hazard pointer code
is gone, and the `isc_loop` module now has its own per-loop thread
IDs.
The trampoline machinery seems over-complicated for its remaining
tasks, so move the per-thread initialization into `isc/thread.c`,
and delete the rest.
The isc_time_now() and isc_time_now_hires() were used inconsistently
through the code - either with status check, or without status check,
or via TIME_NOW() macro with RUNTIME_CHECK() on failure.
Refactor the isc_time_now() and isc_time_now_hires() to always fail when
getting current time has failed, and return the isc_time_t value as
return value instead of passing the pointer to result in the argument.
The isc_fsaccess API was created to hide the implementation details
between POSIX and Windows APIs. As we are not supporting the Windows
APIs anymore, it's better to drop this API used in the DST part.
Moreover, the isc_fsaccess was setting the permissions in an insecure
manner - it operated on the filename, and not on the file descriptor
which can lead to all kind of attacks if unpriviledged user has read (or
even worse write) access to key directory.
Replace the code that operates on the private keys with code that uses
mkstemp(), fchmod() and atomic rename() at the end, so at no time the
private key files have insecure permissions.
As it's impossible to get the current umask without modifying it at the
same time, initialize the current umask at the program start and keep
the loaded value internally. Add isc_os_umask() function to access the
starttime umask.
The only place where dns_name_hash() was being used is the old hash
table in the dns_badcache unit. Squash the dns_name_fullhash() and
dns_name_hash() into single dns_name_hash() function that's always
case-insensitive as it doesn't make to do case-sensitive hashing of the
domain names and we were not using this anywhere.
