Description

A Galera cluster uses encryption for SST with the following configuration:

[sst]

encrypt=3

tkey=/path/to/key.pem

tcert=/path/to/cert.pem

tca=/path/to/ca.pem

Upgrading a node to 10.1.28 (in a Galera cluster of 10.1.23 nodes) fails with:

2017-11-04 18:23:17 140462627223296 [Note] WSREP: (3804918b, 'tcp://0.0.0.0:4567') turning message relay requesting off

xb_stream_read_chunk(): wrong chunk magic at offset 0x0.

WSREP_SST: [ERROR] Error while getting data from donor node: exit codes: 137 1 (20171104 18:24:55.419)

WSREP_SST: [ERROR] Cleanup after exit with status:32 (20171104 18:24:55.421)

One explication is that the joiner doesn't expect an encrypted stream, poining at a problem with the configuration under [sst] section.
After some investigation I restricted the problem to the wsrep_sst_xtrabackup-v2's function parse_cnf() which was moved to wsrep_sst_common.

In 10.1.23 parse_cnf() is in wsrep_sst_xtrabackup-v2 and it's:

parse_cnf()

    local group=$1

    local var=$2

    # print the default settings for given group using my_print_default.

    # normalize the variable names specified in cnf file (user can use _ or - for example log-bin or log_bin)

    # then grep for needed variable

    # finally get the variable value (if variables has been specified multiple time use the last value only)

    reval=$($MY_PRINT_DEFAULTS $group | awk -F= '{if ($1 ~ /_/) { gsub(/_/,"-",$1); print $1"="$2 } else { print $0 }}' | grep -- "--$var=" | cut -d= -f2- | tail -1)

    if [[ -z $reval ]];then

        [[ -n $3 ]] && reval=$3

fi

    echo $reval

In 10.1.28 it's moved to wsrep_sst_common and it's:

parse_cnf()

    local group=$1

    local var=$2

    local reval=""

    # print the default settings for given group using my_print_default.

    # normalize the variable names specified in cnf file (user can use _ or - for example log-bin or log_bin)

    # then grep for needed variable

    # finally get the variable value (if variables has been specified multiple time use the last value only)

    # look in group+suffix

    if [[ -n $WSREP_SST_OPT_CONF_SUFFIX ]]; then

        reval=$($MY_PRINT_DEFAULTS -c $WSREP_SST_OPT_CONF "${group}${WSREP_SST_OPT_CONF_SUFFIX}" | awk -F= '{if ($1 ~ /_/) { gsub(/_/,"-",$1); print $1"="$2 } else { print $0 }}' | grep -- "--$var=" | cut -d= -f2- | tail -1)

fi

    # look in group

    if [[ -z $reval ]]; then

        reval=$($MY_PRINT_DEFAULTS -c $WSREP_SST_OPT_CONF $group | awk -F= '{if ($1 ~ /_/) { gsub(/_/,"-",$1); print $1"="$2 } else { print $0 }}' | grep -- "--$var=" | cut -d= -f2- | tail -1)

fi

    # use default if we haven't found a value

    if [[ -z $reval ]]; then

        [[ -n $3 ]] && reval=$3

fi

    echo $reval

Using wsrep_sst_common and wsrep_sst_xtrabackup-v2 from version 10.1.23 on 10.1.28 fixes the problem and the node succesfully joins.
