Git 2.54.0-rc0 Breaks on OpenSSL 3.0

Git 2.54.0-rc0 Breaks on OpenSSL 3.0

[rsbecker]

Sadly, OpenSSL 3.0 is still out in the wild for those who have extended
support contracts with OpenSSL. The following errors happen using OpenSSL
3.0 when built with c99:

"/home/jenkinsbuild/.jenkins/workspace/Git_Pipeline/imap-send.c", line 274:
error(252):
          argument of type "const X509_NAME_ENTRY *" is incompatible with
          parameter of type "X509_NAME_ENTRY *" (aka "struct
X509_name_entry_st
          *")

                                     ASN1_STRING_get0_data(cname),
hostname);
                                     ^
"/home/jenkinsbuild/.jenkins/workspace/Git_Pipeline/imap-send.c", line 279:
error(114):
          identifier "ASN1_STRING_get0_data" is undefined

Sincerely,
Randall

https://openssl-library.org/policies/releasestrat/index.html says
"Version 3.0 will be supported until 2026-09-07 (LTS)".

This line contains:

	    (cname = X509_NAME_ENTRY_get_data(cname_entry)) == NULL)

https://docs.openssl.org/3.0/man3/X509_NAME_ENTRY_get_object/ gives its
prototype as:

ASN1_STRING *X509_NAME_ENTRY_get_data(const X509_NAME_ENTRY *ne);

This has been matching the code since OpenSSL commit 9f5466b9b8
(Constify some X509_NAME, ASN1 printing code, 2016-07-07).  git describe
calls this commit OpenSSL_1_1_0-pre6-232-g9f5466b9b8.

https://docs.openssl.org/3.0/man3/ASN1_STRING_length/ gives its
prototype as:

const unsigned char *ASN1_STRING_get0_data(const ASN1_STRING *x);

It was added by OpenSSL commit 17ebf85abd (Add ASN1_STRING_get0_data(),
deprecate ASN1_STRING_data()., 2016-08-16).  git describe calls this
commit OpenSSL_1_1_0-pre6-119-g17ebf85abd.

Are you sure you use OpenSSL 3.0?  The errors suggest it's a rather
older version (before 1.1.1).

Thanks Rene. Operator (me) error here. This was on the 1.0.2w build. We are disabling that
build now so that it will not get reported again.

Regards and thanks,
