From: Jérémie Galarneau Date: Sat, 7 Apr 2018 20:04:51 +0000 (-0400) Subject: Increase LTTNG_HOST_NAME_MAX from 64 to 255 X-Git-Tag: v2.11.0-rc1~282 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=b867041c62b48e89c9f00430cde4c33f13a2da09;p=lttng-tools.git Increase LTTNG_HOST_NAME_MAX from 64 to 255 POSIX guarantees that a host name will not exceed 255 characters. Moreover, RFC 1035 limits the length of a fully qualified domain name (FQDN) to 255 characters. This limit will be used as part of the lttngctl communication protocol.
