(ITS#9177) Finish the autoconf 2.69 upgrade
by ryan＠openldap.org 28 Feb '20

28 Feb '20

Full_Name: Ryan Tandy Version: master OS: URL: Submission from: (NULL) (70.66.128.207) Submitted by: ryan autoconf 2.69 upgrade was only partially completed. So far we have autoconf (6b81910fc) and autoheader (c2f75cd10). However running autoreconf 2.69 still generates more diffs. At least aclocal still needs to be run. This ITS is a reminder to check what else autoreconf does and check in the remaining changes. In future it might be good practice to get in the habit of running autoreconf instead of just autoconf. It tries and fails to run Automake, but that can probably be addressed (possibly by deleting the AM_INIT_AUTOMAKE call).

Are you aware of any scenarios where sambaLMPassword is actually required today? Personally I'm more inclined to just delete the code rather than #ifdef it; people can always grab the older code if they really need that.

Re: (ITS#9175) ldapsearch segfault
by lhaley＠meditech.com 21 Feb '20

21 Feb '20

--00000000000062d6a8059f1bda34 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable FOUND THE ISSUE! So - in GDB , while paused in the "{mM}" processing that ber_scanf does (called from ldap_get_attribute_ber), I kept seeing the variable arguments list not properly setting off --- and sure enough, digging in memory, on the stack was 0x100000000 ... which was the cause of the eventual segfault. Well, backtracking to the ber_scanf call itself, I see a zero 0 which isn't cast to the ber_len_t type, and as such, will only occupy 4 bytes as a sizeof int - instead of (( on my system 8, for sizeof (ber_len_t). So - the solution was just to cast the argument. So that the cookie.off =3D va_arg( ap, ber_len_t ); will unpack only bytes we've intentionally sent it -- not garbage left over. So - the change suggested is: diff --git a/libraries/libldap/getattr.c b/libraries/libldap/getattr.c index 31784d765..0300ea574 100644 --- a/libraries/libldap/getattr.c +++ b/libraries/libldap/getattr.c @@ -147,7 +147,7 @@ ldap_get_attribute_ber( LDAP *ld, LDAPMessage *entry, BerElement *ber, /* skip sequence, snarf attribute type */ tag =3D ber_scanf( ber, vals ? "{mM}" : "{mx}", attr, vals, - &siz, 0 ); + &siz, (ber_len_t)0 ); if( tag =3D=3D LBER_ERROR ) { rc =3D ld->ld_errno =3D LDAP_DECODING_ERROR; } I hope you can take this haphazard issue submit, and do whatever is right with it - to get this patch considered.
