(ITS#9076) back-ldap tries to free the wrong controls
by ondra＠openldap.org 10 Sep '19

10 Sep '19

Full_Name: Ondrej Kuznik Version: re24/master OS: URL: Submission from: (NULL) (82.132.242.212) ldap_back_extended_one needs to play with op->o_ctrls since it doesn't just pass ctrls over like the other sites in back-ldap, but it never sets oldctrls as is should. If a control is ever added to the list, it will restore op->o_ctrls to the wrong value and crash. This happens e.g. in certain chaining scenarios with mode=legacy.

Not sure which code you think would overwrite parts of the buffer? ber_str2bv(,,0,) never touches it, manually initialising the berval certainly wouldn't either. And then you have fewer memory regions to scrub. Since you already know the length, you can also pass it in so ber_str2bv can skip its strlen() check (and since anything can be in a {PLAINTEXT} password, you're now embedded NUL safe). >> Just a style note, if there's an else coming, could you make sure both >> the if and the else blocks are in {}? > > Implemented, it will be included in the updated patches. I think I mentioned this before as something worth changing: rather than call time(0L), you can use op->o_time which is stable and the closest you can get to the time the operation was received. BTW, scinet.supercomputing.org's HTTPS cert is signed by Let's Encrypt Authority X3 as an intermediate, but isn't sending it during the handshake, so wget/curl aren't happy trusting it (I think browsers cache it or already have a copy).

Re: (ITS#9069) Stop setting custom GnuTLS mutex functions
by ryan＠nardis.ca 06 Sep '19

06 Sep '19

I know the locking gets exercised (both libldap and GnuTLS sides) during connection and TLS handshake, so I tested this by doing a bind/search/unbind loop on a bunch of parallel threads. I built master with this patch in all of the following environments: Debian 8 (jessie), GnuTLS 3.3.30 Debian 9 (stretch), GnuTLS 3.5.8 Debian 10 (buster), GnuTLS 3.6.7 Debian unstable (sid), GnuTLS 3.6.9 FreeBSD 12.0, GnuTLS 3.6.8 Solaris 11.4, GnuTLS 3.5.16, --with-threads=lwp Solaris 11.4, GnuTLS 3.5.16, --with-threads=posix Windows 10 (MinGW), GnuTLS 3.6.8, --with-threads=nt Windows 10 (MinGW), GnuTLS 3.6.8, --with-threads=posix and ran my test program successfully on all of them. On each of these I also stepped into the debugger and confirmed that the expected calls happened (gnutls_system_mutex_lock calling resp. pthread_mutex_lock or EnterCriticalSection, ldap_pvt_thread_mutex_lock calling the expected API, etc). Any further comments, or suggestions for additional tests I should run?

Are you referring to the chk_totp_and_pw() function? If so, since the expected format is <password><totp> with no seperator, if I terminated the password part that would overwrite the first char of totp, yes? That's the reason I make a copy and allocate an extra byte for the NUL. > Just a style note, if there's an else coming, could you make sure both > the if and the else blocks are in {}?

I would like to see a few changes though: - could you split it in two patches, one to check the previous time step (+doc) and one to support the new schemes (+doc)? - I don't think you need to allocate a copy of the passwd just come in, you can just frame it into separate bervals reusing the provided buffer so long as you keep in mind they are not NUL-terminated properly.

Re: (ITS#8383) msys build error "portable.h:1116:19: error: two or more data types in declaration specifiers"
by ryan＠nardis.ca 01 Sep '19

01 Sep '19

I've run into this myself while trying to test ITS#9069 on Windows. In my MinGW environment, <sys/socket.h> does not define socklen_t, so portable.h:1116 does '#define socklen_t int'. However, <ac/socket.h> includes <ws2tcpip.h> which does typedef socklen_t. base64.c includes "portable.h" first and then <ac/socket.h> later. This second include triggers the error as the original typedef essentially becomes "typedef int int". I think we can fix it by searching the Windows header as well, avoiding the #define appearing in "portable.h". https://github.com/openldap/openldap/compare/openldap:master...rtandy:its83…
