Bug#34171 - "Backup: ignoring --secure-file-priv"
Before patch: Backup code ignored secure-file-priv option,
allowing backup to write to any location
After patch: Backup and restore are not allowed to write or read
outside path in secure-file-priv option if option has been
specified.
added:
mysql-test/r/backup_securefilepriv.result
mysql-test/t/backup_securefilepriv-master.opt

per-file comments:
mysql-test/lib/mtr_report.pl
Added expected error for backup_securefilepriv
mysql-test/r/backup_backupdir.result
Result modified to handle modified test file due to secure_file_priv
mysql-test/r/backup_securefilepriv.result
New result file for secure-file-priv backup tests
mysql-test/t/backup_backupdir.test
Tests modified to handle secure_file_priv
mysql-test/t/backup_securefilepriv-master.opt
Sets secure-file-priv option for backup_securefilepriv test
mysql-test/t/backup_securefilepriv.test
New test file for secure-file-priv backup tests
sql/backup/kernel.cc
Improved error handling for errors reported by *Stream::open
sql/backup/stream.cc
Adds check for secure-file-priv option when opening backup/restore streams. Also some doc-bug fixes for Stream::prepare_path
sql/backup/stream.h
Added private method test_secure_file_priv_access, *Stream::open() now returns int
