Author: ngie Date: Fri Jun 2 00:27:08 2017 New Revision: 319483 URL: https://svnweb.freebsd.org/changeset/base/319483 Log: MFC r318210: ssp_test:read:: query the value of MAXPATHLEN via getconf(1) In the event the value of PATH_MAX was changed, the assumption that MAXPATHLEN is 1024 (and hence the buffer length required to trigger SSP to fail for read(2)) would be invalidated. Query getconf(1) for the actual value of MAXPATHLEN via _XOPEN_PATH_MAX instead, and increment the value by 1 to ensure that the SSP support tests the stack smashing support properly.
