The recent upgrade of (probably one of) talloc/tevent/tdb breaks samba, specifically smbd. I tried rebuilding samba36, to no avail. The interesting part may be "Bad talloc magic value - unknown value" in the second log below. log.smbd shows the following: [2017/01/07 18:16:30, 0] smbd/server.c:1072(main) smbd version 3.6.25 started.

Upgrade of devel/tevent to 0.9.31 breaks samba-libsmbclient (and ports that depend on it) as well. Downgrading to tevent-0.9.28 fixes it.

(In reply to Alexander Moisseev from comment #2) Well, it's getting awkward now. s samba3* been deprecated for few years now, the best solution would be to utilize libsmbclient from samba4.

up is a difficult process.
(In reply to Timur I. Bakeyev from comment #5) On other side, for samba3: ./libsmbclient.so: libc.so.7 => /lib/libc.so.7 (0x800822000) libtalloc.so.2 => /usr/local/lib/libtalloc.so.2 (0x801b17000) libtevent.so.0 => /usr/local/lib/libtevent.so.0 (0x801d25000) libtdb.so.1 => /usr/local/lib/libtdb.so.1 (0x801f35000) libexecinfo.so.1 => /usr/lib/libexecinfo.so.1 (0x80214a000) libmd.so.6 => /lib/libmd.so.6 (0x80234d000) libz.so.6 => /lib/libz.so.6 (0x80255d000) libthr.so.3 => /lib/libthr.so.3 (0x802773000) librt.so.1 => /usr/lib/librt.so.1 (0x802997000) libcrypt.so.5 => /lib/libcrypt.so.5 (0x802b9d000) libelf.so.1 => /usr/lib/libelf.so.1 (0x802dbd000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x802fd2000) So, I see the best ad-hoc solution would be to take samba36 code, enable built-in talloc and friends and compile library directly from the samba36 source, breaking master-slave linkage, as samba36 has open CVE and is deprecated. Well, going to implement that.
Hi, there is another bug related to this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=216230
(In reply to Timur I. Bakeyev from comment #6) (In reply to Matthias Petermann from comment #7) So I fear fixing this issue locally in Samba 36 does not resolve the general issue brought by the upgrade of tevent to 0.9.31.
