+【Issue#1031 動作確認】
+Issue#1031が解決され、既存機能に影響がないことをIssueで報告されたテストプログラム（1項目）と、
+McKernelでのsigaction()の基本動作確認（10項目）の計11項目のテストによって確認した。
+なお、各テストの実行結果は./result.log として格納している。
+
+①Issueで報告されたテストプログラムによる確認
+ ・Issue#1031
+ 報告で使用されたテストプログラムを用いて、現象が再現しないことを確認した。
+ 実行時の出力を./result.log に記載している
+ 
+②McKernelでのsigaction()の基本動作確認
+以下の内容で、Issue#1031による変更が既存機能に影響しないことを確認した。
+
+基本動作確認の詳細を以下に示す。
+
+1. テストの実行方法
+ 以下の手順でテストを実行する
+	1. Makefileの変数MCK_DIRの内容を、McKernelがインストールされているディレクトリに変更する
+	2. sh make test を実行する
+
+2. テスト項目
+CT_001: SIG_RESETHAND 指定時の動作
+	1. SIG_RESETHANDを指定したsigaction()でSIG_USR1にハンドラを設定
+	2. 自身にSIGUSR1を送る
+	3. 1.で登録したハンドラが呼び出される
+	4. 自身にSIGUSR1を送る
+	5. 1.で登録したハンドラが呼び出されず、プロセスが終了する
+
+CT_002: SIG_RESETHAND 未指定時の動作
+	1. SIG_RESETHANDを指定しないsigaction()でSIGUSR1にハンドラを設定
+	2. 自身にSIGUSR1を送る
+	3. 1.で登録したハンドラが呼び出される
+	4. 自身にSIGUSR1を送る
+	5. 1.で登録したハンドラが呼び出される
+
+CT_003: SIG_RESETHANDO 指定ハンドラへの上書き登録時の動作
+	1. SIG_RESETHANDを指定したsigaction()でSIG_USR1にハンドラを設定
+	2. SIG_RESETHANDを指定しないsigaction()でSIG_USR1にハンドラを設定
+	3. 自身にSIGUSR1を送る
+	4. 2.で登録したハンドラが呼び出される
+	5. 自身にSIGUSR1を送る
+	6. 2.で登録したハンドラが呼び出される
+
+CT_004: 複数のsig_numへのハンドラ登録時の動作
+	1. SIG_RESETHANDを指定したsigaction()でSIG_USR1にハンドラを設定
+	2. SIG_RESETHANDを指定したsigaction()でSIG_USR2にハンドラを設定
+	3. 自身にSIGUSR1を送る
+	4. 1.で登録したハンドラが呼び出される
+	5. 自身にSIGUSR2を送る
+	6. 2.で登録したハンドラが呼び出される
+	7. 自身にSIGUSR1を送る
+	8. 1.で登録したハンドラが呼び出されず、プロセスが終了する
+
+CT_005: 複数回(非上書き)のSIG_RESETHAND 指定時の動作
+	1. SIG_RESETHANDを指定したsigaction()でSIG_USR1にハンドラを設定
+	2. 自身にSIGUSR1を送る
+	3. 1.で登録したハンドラが呼び出される
+	4. SIG_RESETHANDを指定したsigaction()でSIG_USR1にハンドラを設定
+	5. 自身にSIGUSR1を送る
+	6. 4.で登録したハンドラが呼び出される
+	7. 自身にSIGUSR1を送る
+	8. 4.で登録したハンドラが呼び出されず、プロセスが終了する
+
+CT_006: 設定中のハンドラ情報の取得 (上書き時)
+	1. SIG_RESETHANDを指定したsigaction()でSIG_USR1にハンドラを設定
+	2. sigaction(SIGUSR1, NULL, &act) で設定情報を取得
+	3. SIG_RESETHANDを指定しないsigaction()でSIG_USR1にデフォルトハンドラを設定
+	4. sigaction(SIGUSR1, NULL, &act) で設定情報を取得
+
+CT_007: 設定中のハンドラ情報の取得 (デフォルトに戻った時)
+	1. SIG_RESETHANDを指定したsigaction()でSIG_USR1にハンドラを設定
+	2. 自身にSIGUSR1を送る
+	3. 1.で登録したハンドラが呼び出される
+	4. sigaction(SIGUSR1, NULL, &act) で設定情報を取得
+
+CT_008: 不正なsig_numへのハンドラ登録
+	1. 範囲外(上限、下限)のsignumへのハンドラ登録
+	2. SIGKILL, SIGSTOPへのハンドラ登録
+
+CT_009: SIGKILL, SIGSTOPのハンドラ情報の取得
+	1. sigaction(SIGKILL, NULL, &act) で設定情報を取得
+	2. sigaction(SIGSTOP, NULL, &act) で設定情報を取得
+
+CT_010: sig_numの有効確認
+	1. sigaction(SIGUSR1, NULL, NULL) で有効かどうかを確認
+	2. sigaction(SIGKILL, NULL, NULL) で有効かどうかを確認
+	3. sigaction(SIGSTOP, NULL, NULL) で有効かどうかを確認
+
+3. 結果
+テストプログラムの実行結果をresult.log に示す。
+上記の11項目がPASSしていることを確認した。

+【Issue#863 動作確認】
+1. Issue#863および、同件のIssue#870で指摘されたテストプログラムを用いて
+   現象が解消されていることを確認した。(2件)
+   実行結果(エビデンス)は以下の通り。
+
+CT1001.txt Issue#863の指摘で使用されたテストプログラムの実行結果(OK 1件、NG 0件)
+CT2001.txt Issue#870の指摘で使用されたテストプログラムの実行結果(OK 1件、NG 0件)
+
+2. Issue#863の変更が既存シグナル機能に影響しないことを確認した。
+   確認内容は以下の通り。
+
+CT3001 遅いI/Oシステムコール実行中にシグナルを受け、即座にシグナル
+       ハンドラが呼び出され、システムコールがEINTRを返却することを
+       確認する。
+CT3002 遅くないI/Oシステムコール実行中にシグナルを受け、システム
+       コール完了後にシグナルハンドラが呼び出され、システムコール
+       が正常に終了することを確認する。
+CT3003 遅いI/Oシステムコール実行中にプログラムを終了するシグナルを
+       受けとると、即座にプログラムが終了することを確認する。
+CT3004 遅くないI/Oシステムコール実行中にプログラムを終了するシグナル
+       を受けとると、即座にプログラムを終了することを確認する。
+CT3005 遅いI/Oシステムコール実行中にプログラムを終了しないシグナル(SIGURG)
+       を受けとっても、プログラムの実行に影響しないことを確認する。
+CT3006 遅くないI/Oシステムコール実行中にプログラムを終了しないシグナル
+       (SIGURG)を受けとっても、プログラムの実行に影響しないことを確認する。
+CT3007 遅いI/Oシステムコール実行中に無視(SIG_IGN)するシグナルを
+       受けとっても、プログラムの実行に影響しないことを確認する。
+CT3008 遅くないI/Oシステムコール実行中に無視(SIG_IGN)するシグナルを
+       受けとっても、プログラムの実行に影響しないことを確認する。
+
+CT300x の実行は、make test で行う。
+エビデンスは CT300x.txt に示す。(OK 8件、NG 0件)

+【Issue#882 動作確認】
+1. Issue#882で指摘されたテストプログラムを用いて現象が解消されていることを
+   確認した。(テストプログラム1本、確認項目3件)
+   実行結果(エビデンス)は以下の通り。
+
+CT1001-3.txt Issue#882の指摘で使用されたテストプログラムの実行結果
+             (OK 3件、NG 0件)
+     McKernelにプロセス残留が無いこと(ihkosctl 0 ioctl 40000000 1の結果 0)
+     McKernelにスレッド残留が無いこと(ihkosctl 0 ioctl 40000000 2の結果 0)
+     Linuxにmcexecプロセス残留が無いこと(ps axg|grep mcexecの結果、プロセスなし)
+
+尚、タイミングによって発生しない可能性があるため、複数回(5回以上)繰り返し実行
+し、再発しないことを確認した。
+
+2. Issue#882の変更が既存fork機能に影響しないことをLTPを用いて確認した。
+   (テストプログラム6本、確認項目12件)
+   実行結果(エビデンス)は以下の通り。
+
+fork01.txt fork後に子プロセスのプロセスIDが正しいことを確認 (OK 2件)
+fork02.txt fork後にwaitを行い、waitが子プロセスのPIDを返却することを確認(OK 1件)
+fork03.txt forkで生成した子プロセスが処理を行った後でもfork返却値に変化が無い
+           (親プロセス側の返却値で上書きされていない)ことを確認 (OK 1件)
+fork04.txt forkで生成した子プロセスが環境変数を変更しても、親プロセス側の
+           環境変数に変化が無いことを確認 (OK 3件)
+fork07.txt forkした子プロセスに、親プロセスからファイルディスクリプタを
+           引き継いでいることを確認 (OK 1件)
+fork08.txt forkした複数の子プロセスが、それぞれ親プロセスから引き継いだファイル
+           ディスクリプタを別個に操作できることを確認
+           (ある子プロセスがcloseしても別な子プロセスがI/O可能) (OK 4件)

+【Issue#885 動作確認】
+Issue#885が解決され、既存機能に影響がないことをIssueで報告されたテストプログラム（2項目）と、
+McKernelでのptraceのattach/detach操作の基本動作確認（8項目）の計10項目のテストによって確認した。
+なお、各テストの実行結果は./result.log として格納している。
+
+①Issueで報告されたテストプログラムによる確認
+ ・Issue#885
+ 報告で使用されたテストプログラムを用いて、現象が再現しないことを確認した。
+ 実行時の出力を./result.log に記載している
+ 
+②McKernelでのptraceのattach/detachの基本動作確認
+以下の内容で、Issue#885による変更が既存機能に影響しないことを確認した。
+
+基本動作確認の詳細を以下に示す。
+
+1. テストの実行方法
+ 以下の手順でテストを実行する
+	1. Makefileの変数MCK_DIRの内容を、McKernelがインストールされているディレクトリに変更する
+	2. sh make test を実行する
+
+2. テスト項目
+CT_001: 通常のattach detach 操作
+	1. 親プロセスが子プロセスにattach
+	2. 親プロセスが子プロセスをdetach
+	3. 子プロセスが終了
+	4. 親プロセスがwait()で子プロセスの終了を回収
+
+CT_002: tracee(子プロセス)がdetachせずに終了
+	1. 親プロセスが子プロセスにattach
+	2. 子プロセスが終了
+	3. 親プロセスがwait()で子プロセスの終了を回収
+
+CT_003: tracer(親プロセス)がdetachしないまま先に終了
+	1. 親プロセスが子プロセスにattach
+	2. 親プロセスが子プロセスに再開指示した直後に終了
+	3. 子プロセスが終了
+
+CT_004: 複数回のattach -> detach 操作
+	1. 親プロセスが子プロセスにattach
+	2. 親プロセスが子プロセスにdetach
+	3. 再び、親プロセスが子プロセスにattach
+	4. 親プロセスが子プロセスにdetach
+
+CT_005: 不正なpid指定のattach
+	1. 不正なpid(0, 1, 負数)を指定したattach
+	2. 自身のpidを指定したattach
+
+CT_006: attach済の子プロセスへのattach
+	1. 既にattachしている子プロセスへ再びattach
+	2. tracemeした子プロセスへattach
+
+CT_007: 不正なpid指定のdetach
+	1. 不正なpid(0, 1, 負数)を指定したdetach
+	2. attachしていない子プロセスのpidを指定したdetach
+
+CT_008: detach済の子プロセスへのdetach
+	1. 既にdetachしていいる子プロセスへ再びdetach
+
+3. 結果
+テストプログラムの実行結果をresult.log に示す。
+上記の10項目がPASSしていることを確認した。

+【Issue#898,#928 動作確認】
+Issue#898, #928が解決され、既存機能に影響がないことをihklibテストスイートを用いた確認（2項目）と、
+McKernelの起動/終了の基本動作確認（9項目）の計11項目のテストによって確認した。
+
+①ihklibテストスイートを用いた確認
+ ・Issue#898
+ ihklibテストスイートのihklib001_lin.c を以下のように修正して1000回繰り返し実行し、
+ すべての実行においてテストをパスすることを確認した。
+  - McKernelのブート処理の直後にgoto文を追加し、シャットダウン処理の直前に移動する
+
+ ・Issue#928
+ ihklibテストスイートのihklib001_lin.c を以下のように修正して1000回繰り返し実行し、
+ すべての実行においてテストをパスすることを確認した。
+  - McKernelプロセス(mcexec)の実行直後にgoto文を追加し、シャットダウン処理の直前に移動する
+ 
+②McKernelの起動/終了の基本動作確認
+McKernelの状態と、終了処理(shutdown, destroy)の組み合わせで、
+9項目のテストを実施した。
+
+基本動作確認の詳細を以下に示す。
+
+1. ファイルの説明
+  CT_xxx.c              各テスト項目のテストプログラム
+  force_shutdown.patch  McKernelの状態がRUNNINGにならなかった場合に行う強制シャットダウン処理を
+                        発生させるパッチファイル
+  result.log            テストプログラムの実行結果
+
+2. テストの実行方法
+ 以下の手順でテストを実行する
+	1. Makefileの変数MCK_DIRの内容を、McKernelがインストールされているディレクトリに変更する
+	2. CT_xxx.c の定数MCK_DIRの内容を、McKernelがインストールされているディレクトリに変更する
+	3. sh make test を実行する
+
+3. テスト項目
+以下の条件でMcKernelの起動/終了が正常に行われることを確認する
+なお、McKernelの起動、終了の操作はihklibを用いて実施する
+
+CT_001:
+	1. McKernelを起動(ihk_os_boot)する
+	2. 起動の直後にMcKernelを終了(ihk_os_shutdown)する
+	⇒ ihk_os_shutdownが0を返す
+
+CT_002:
+	1. McKernelを起動(ihk_os_boot)する
+	2. 起動の直後に対象のIHK_OSインスタンスを破棄(ihk_os_destroy)する
+	⇒ ihk_os_destroyが0を返す
+
+CT_003:
+	1. McKernelを起動(ihk_os_boot)する
+	2. McKernelプロセスを実行する
+	3. McKernelプロセスの実行終了直後にMcKernelを終了(ihk_os_shutdown)する
+	⇒ ihk_os_shutdownが0を返す
+
+CT_004:
+	1. McKernelを起動(ihk_os_boot)する
+	2. McKernelプロセスを実行する
+	3. McKernelプロセスの実行終了直後に対象のIHK_OSインスタンスを破棄(ihk_os_destroy)する
+	⇒ ihk_os_destroyが0を返す
+
+CT_005:
+	1. McKernelを起動(ihk_os_boot)する
+	2. McKernelプロセスを実行する
+	3. McKernelプロセスの実行中にMcKernelを終了(ihk_os_shutdown)する
+	⇒ ihk_os_shutdownが0を返す
+
+CT_006:
+	1. McKernelを起動(ihk_os_boot)する
+	2. McKernelプロセスを実行する
+	3. McKernelプロセスの実行中に対象のIHK_OSインスタンスを破棄(ihk_os_destroy)する
+	⇒ ihk_os_destroyが0以外を返す (ref_count != 0)
+
+CT_007:
+	1. McKernelの起動処理の中の、カーネルイメージのロード(ihk_os_load)までを実施する
+	2. McKernelを終了(ihk_os_shutdown)する
+	⇒ ihk_os_shutdownが0を返す
+
+CT_008:
+	1. McKernelを起動(ihk_os_boot)する
+	2. McKernelプロセスを実行する
+	3. McKernelプロセスの実行終了直後にMcKernelを終了(ihk_os_shutdown)する
+	4. ihk_os_get_status がSHUTDOWNまたは、INACTIVEを返すことを確認する
+	5. 終了したMcKernelに対して、再度終了(ihk_os_shutdown)する
+	⇒ ihk_os_shutdownが0以外を返す
+
+CT_009:
+	前提：force_shutdown.patch を適用してMcKernelをビルドする
+	1. McKernelを起動(ihk_os_boot)する
+	2. 起動の直後にMcKernelを終了(ihk_os_shutdown)する
+	⇒ ihk_os_shutdownが0を返す
+
+4. 結果
+テストプログラムの実行結果はresult.log に出力される。
+上記9項目で[OK]が出力されていることを確認した。

+【Issue#925 動作確認】
+Issue#925が解決され、既存機能に影響がないことをIssueで報告されたテストプログラム（1項目）と、
+McKernelでのXPMEM操作の基本動作確認（11項目）の計12項目のテストによって確認した。
+なお、各テストの実行結果は./result.log として格納している。
+
+①Issueで報告されたテストプログラムによる確認
+ ・Issue#925
+ 報告で使用されたテストプログラムを用いて、現象が再現しないことを確認した。
+ 実行時の出力を./result.log に記載している
+ 
+②McKernelでのXPMEM操作の基本動作確認
+以下の内容で、Issue#925による変更が既存機能(XPMEM)に影響しないことを確認した。
+
+基本動作確認の詳細を以下に示す。
+
+1. テストの実行方法
+ 以下の手順でテストを実行する
+	1. Makefileの変数MCK_DIRの内容を、McKernelがインストールされているディレクトリに変更する
+	2. Makefileの変数XPMEM_DIRの内容を、XPMEMライブラリがインストールされているディレクトリに変更する
+	3. sh make test を実行する
+
+2. テスト項目
+CT_001: 単一プロセスでのXPMEM操作
+	1. 実行したプロセスがxpmem_make -> xpmem_get -> xpmem_attach -> xpmem_detach -> xpmem_remove
+
+CT_002: 子プロセスでのXPMEM操作
+	1. 親プロセスがfork()
+	2. 子プロセスがxpmem_make -> xpmem_get -> xpmem_attach -> xpmem_detach ->xpmem_remove
+	3. 子プロセス終了後、親プロセスが終了
+
+CT_003: 親プロセスがmakeした共有領域への子プロセスによるXPMEM操作
+	1. 親プロセスがxpmem_make
+	2. fork()で子プロセスを作成
+	3. 子プロセスで、xpmem_get -> xpmem_attach -> 値(TEST_VAL)の設定 -> xpmem_detach
+	4. 子プロセスが終了
+	5. 親プロセスが、子プロセスによって設定された値(TEST_VAL)を確認
+	6. 親プロセスがxpmem_remove
+
+CT_004: fork()後に親プロセスがmakeした共有領域への子プロセスによるXPMEM操作
+	1. fork()で子プロセスを作成
+	2. 親プロセスがxpmem_make
+	3. 子プロセスで、xpmem_get -> xpmem_attach -> 値(TEST_VAL)の設定 -> xpmem_detach
+	4. 子プロセスが終了
+	5. 親プロセスが、子プロセスによって設定された値(TEST_VAL)を確認
+	6. 親プロセスがxpmem_remove
+
+CT_005: 子プロセスがxpmem_attach後、xpmem_detachをせずに終了
+	1. 親プロセスがxpmem_make
+	2. fork()で子プロセスを作成
+	3. 子プロセスで、xpmem_get -> xpmem_attach
+	4. 子プロセスが終了
+	5. 親プロセスがxpmem_remove
+
+CT_006: 子プロセスがXPMEM操作を行う時点で、xpmem_makeをした親プロセスが終了している
+	1. 親プロセスがxpmem_make
+	2. fork()で子プロセスを作成
+	3. 親プロセスが終了
+	4. 子プロセスで、xpmem_get (失敗)
+	5. 子プロセスが終了
+
+CT_007: xpmem_make 呼び出しの異常系
+	1. xpmem_make の第1引数に不正なアドレスを指定する (失敗)
+	2. 1度xpmem_make を実施したメモリ領域に対して、再度xpmem_make を行う (成功)
+
+CT_008: xpmem_get 呼び出しの異常系
+	1. xpmem_get の第1引数に不正なsegidを指定する (失敗)
+	2. 1度xpmem_get を実施したsegidで、再度xpmem_get を行う (成功)
+	
+CT_009: xpmem_attach 呼び出しの異常系
+	1. xpmem_attach の第1引数に不正なapidを指定する (失敗)
+	2. 1度xpmem_attach を実施したapidで、再度xpmem_attach を行う (成功)
+
+CT_010: xpmem_detach 呼び出しの異常系
+	1. xpmem_detach の第1引数に不正なアドレスを指定する (成功)
+	2. 1度xpmem_detach を実施したメモリ領域に対して、再度xpmem_detach を行う (成功)
+
+CT_011: xpmem_remove 呼び出しの異常系
+	1. xpmem_remove の第1引数に不正なsegidを指定する (失敗)
+	2. 1度xpmem_remove を実施したsegidで、再度xpmem_remove を行う (失敗)
+
+3. 結果
+テストプログラムの実行結果をresult.log に示す。
+上記の11項目がPASSしていることを確認した。
