GSSAPI authentication regression with 2.4.x
by Noah Meyerhans 02 May '25

02 May '25

While preparing the Debian packages of Dovecot 2.4.1, I encountered what appears to be a regression that impacts the ability of some clients to successfully negotiate gssapi/krb5 authentication. The regression has so far been observed in gsasl, which was able to successfully authenticate to 2.3.19 but cannot authenticate to 2.4.1. Mutt is able to successfully authenticate with 2.3.19 and 2.4.1. Doveconf output is attached. The debug logs for both failed (gsasl) and successful (mutt) authentications follow. Note that all logs are from an ephemeral debug environment, and sensitive data is not redacted. I can provide additional information as needed, and can test different code and/or configuration changes. Failed authentication dovecot debug log: Apr 30 13:40:09 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 30 13:40:09 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 30 13:40:09 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libmech_gssapi.so Apr 30 13:40:09 auth: Debug: Read auth token secret from /home/noahm/dovecot-root/b/auth-token-secret.dat Apr 30 13:40:09 auth: Debug: conn unix:login (pid=6791,uid=1000) [1]: Server accepted connection (fd=18) Apr 30 13:40:09 auth: Debug: conn unix:login (pid=6791,uid=1000) [1]: auth client connected (pid=6791) Apr 30 13:40:09 auth: Debug: conn unix:login (pid=6791,uid=1000) [1]: client in: AUTH 1 GSSAPI protocol=imap final-resp-ok session=FhRIDv8zdMzAqAHa lip=172.18.0.205 rip=192.168.1.218 lport=17436 rport=52340 Apr 30 13:40:09 auth(?,192.168.1.218,sasl:gssapi)<FhRIDv8zdMzAqAHa>: Debug: gssapi: Using all keytab entries Apr 30 13:40:09 auth: Debug: conn unix:login (pid=6791,uid=1000) [1]: client passdb out: CONT 1 # Apr 30 13:40:09 auth: Debug: conn unix:login (pid=6791,uid=1000) [1]: client in: CONT 1 # (previous base64 data may contain sensitive data) Apr 30 13:40:09 auth(?,192.168.1.218,sasl:gssapi)<FhRIDv8zdMzAqAHa>: Debug: gssapi: Processed incoming packet correctly, waiting for another.

Dovecot 3.21.1 -> 2.4.0 SegFault
by Cata S 02 May '25

02 May '25

Hi guys, There seems to be some issue with Dovecot deployed on alpine. More specifically, the dovecot.config file is not properly read. I have run some debugging and the SegFault is returned in the function below: #0 0x000055555556779b in config_parsed_get_setting () No symbol table info available. #1 0x0000555555563708 in config_dump_full () No symbol table info available. #2 0x000055555555c814 in main () No symbol table info available. This was also addressed by alpine here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/17050 Any idea what could be causing this? Thanks for looking into it, Cata
