File size: 103.9 KB
Line 
1
2 * Move AC_CHECK_FUNCS( getnameinfo getaddrinfo ) behind
3 the check for libsocket to have them found on Solaris
4 * Fix IPv4-only bug in bind_addr use in retry_connect()
5 * Add more debug code in connect_port()
6
73.1.5:

9 IPv6 interfaces).
10 * Fix minor issues with bugs in testing code
11 * Add command line option '--server-host' to set the log server
12 * In samhain.startLinux.in start script template, add code to read
13 options from /etc/sysconfig/${NAME} for RedHat
14

18 is specified in the configuration
19 * Fix buffer allocation for getgrnam_r for large groups
20 (problem reported by Sergio B)
21 * Search RPM in $HOME/rpmbuild if test -d _topdir fails (CentOS

37 overflow check (the required buffer length information for the check
38 wasn't provided)
39 * Fixed incorrect logic in setting the ALLIGNORE flag (more specific
