Package: samba Version: 2:4.22.6+dfsg-0+deb13u1 Severity: normal Dear Maintainer,
trying to configure samba to use a different port using the old-style syntax smb ports = tcp:1445 leads to instant crash on samba server and testparm: $ testparm /dev/shm/smb-crash.conf Load smb config files from /dev/shm/smb-crash.conf Error loading services. talloc: access after free error - first free may be at lib/param/loadparm.c:1378 Bad talloc magic value - access after free =============================================================== INTERNAL ERROR: Bad talloc magic value - access after free in testparm () () pid 3990067 (4.22.6-Debian-4.22.6+dfsg-0+deb13u1) If you are running a recent Samba version, and if you think this problem is not yet fixed in the latest versions, please consider reporting this bug, see https://wiki.samba.org/index.php/Bug_Reporting =============================================================== PANIC (pid 3990067): Bad talloc magic value - access after free in 4.22.6-Debian-4.22.6+dfsg-0+deb13u1 BACKTRACE: 8 stack frames: #0 /usr/lib/x86_64-linux-gnu/samba/libgenrand-private-samba.so.0(log_stack_trace+0x2d) [0x7f737aa435bd] #1 /usr/lib/x86_64-linux-gnu/samba/libgenrand-private-samba.so.0(smb_panic+0xd) [0x7f737aa4385d] #2 /lib/x86_64-linux-gnu/libtalloc.so.2(+0x3467) [0x7f737b08e467] #3 /lib/x86_64-linux-gnu/libsmbconf.so.0(+0x43fc0) [0x7f737b0dbfc0] #4 testparm(main+0x6c9) [0x5641631cafd9] #5 /lib/x86_64-linux-gnu/libc.so.6(+0x29ca8) [0x7f737adb8ca8] #6 /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0x85) [0x7f737adb8d65] #7 testparm(_start+0x21) [0x5641631cc8d1] Can not dump core: corepath not set up On trixie, it is possible to use the new-style syntax server smb transports = tcp:1445 which seems to work (did not test actual operation). But on bookworm, that is not supported and one simply cannot start a samba instance on a different port. -- Package-specific info: * Custom smb.conf: [global] security = user map to guest = Bad Password server role = standalone server #server smb transports = tcp:1445 smb ports = tcp:1445 -- System Information: Debian Release: 13.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 6.6.101-rrz9 (SMP w/32 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages samba depends on: ii init-system-helpers 1.69~deb13u1 ii libbsd0 0.12.2-2 ii libc6 2.41-12+deb13u1 ii libcups2t64 2.4.10-3+deb13u2 ii libdbus-1-3 1.16.2-2 ii libgnutls30t64 3.8.9-3+deb13u2 ii libldap2 2.6.10+dfsg-1 ii libldb2 2:2.11.0+samba4.22.6+dfsg-0+deb13u1 ii libpopt0 1.19+dfsg-2 ii libtalloc2 2:2.4.3+samba4.22.6+dfsg-0+deb13u1 ii libtasn1-6 4.20.0-2 ii libtdb1 2:1.4.13+samba4.22.6+dfsg-0+deb13u1 ii libtevent0t64 2:0.16.2+samba4.22.6+dfsg-0+deb13u1 ii libtirpc3t64 1.3.6+ds-1 ii liburing2 2.9-1 ii passwd 1:4.17.4-2 ii procps 2:4.0.4-9 ii samba-common 2:4.22.6+dfsg-0+deb13u1 ii samba-common-bin 2:4.22.6+dfsg-0+deb13u1 ii samba-libs [libndr6] 2:4.22.6+dfsg-0+deb13u1 Versions of packages samba recommends: ii attr 1:2.5.2-3 ii python3-samba 2:4.22.6+dfsg-0+deb13u1 ii samba-ad-dc 2:4.22.6+dfsg-0+deb13u1 Versions of packages samba suggests: pn ctdb <none> pn samba-vfs-ceph <none> pn samba-vfs-glusterfs <none> pn ufw <none> ii winbind 2:4.22.6+dfsg-0+deb13u1 -- no debconf information -- Dr. Thomas Orgis HPC @ Universität Hamburg
