SAL/nfs4_recovery.c: fix the issue where adding export fails when the gethostname function call fails Assuming the value of "sysconf(_SC_HOST_NAME_MAX)" is len. When the actual length of the hostname exceeds (len - 1), calling the gethostname function will result in an error, which can cause the operation of adding new export to fail. This patch allocates 256 bytes of space by default to store the hostname. If the length of the hostname exceeds len, it takes the first len characters. Otherwise, it uses the hostname directly.
