+【Issue#1377 動作確認】
+□ テスト内容
+1. Issue 指摘事項の再現確認
+   現象はタイミングに依存し、ARM64環境でdirtyc0wを繰り返し実行した際に、
+   数回〜数十回に１回程度発生する。
+   問題の発生はタイミングに依存するため、dirtyc0wを十分な回数繰り返し
+   実行し、問題が再発しないことを確認する。
+
+C1377T01 dirtyc0wを1000回連続実行し、全てPASSすることを確認
+
+2. LTP を用いて既存処理に影響しないことを確認
+   プロセスの終了ステータスを変更したため、修正が既存処理に影響しないことを
+   wait系システムコールのLTPを用いて確認する。
+C1377T02 wait02: waitの基本機能の確認
+C1377T03 wait401: wait4の基本機能の確認
+C1377T04 waitpid01: waitpidの基本機能の確認
+C1377T05 waitpid02: waitpidの基本機能の確認
+C1377T06 waitpid04: waitpidの基本機能の確認
+C1377T07 waitpid05: waitpidの基本機能の確認
+C1377T08 waitpid06: waitpidの基本機能の確認
+C1377T09 waitpid07: waitpidの基本機能の確認
+C1377T10 waitpid08: waitpidの基本機能の確認
+C1377T11 waitpid09: waitpidの基本機能の確認
+C1377T12 waitpid10: waitpidの基本機能の確認
+C1377T13 waitpid11: waitpidの基本機能の確認
+C1377T14 waitpid12: waitpidの基本機能の確認
+C1377T15 waitpid13: waitpidの基本機能の確認
+
+□ 実行手順
+$ make test
+
+McKernelのインストール先や LTP の配置場所は、$HOME/.mck_test_config を
+参照する。.mck_test_config は、McKernel をビルドした際に生成される
+mck_test_config.sample ファイルを $HOME にコピーし、適宜編集すること。
+
+□ 実行結果
+C1377_x86_64.txt(x86_64実行結果)、C1377_arm64.txt(arm64実行結果)参照。
+全ての項目が PASS していることを確認。

+【Issue#1389 動作確認】
+□ テスト内容
+本Issueの対応で、sysinfo()と/proc/meminfo の下記項目においてMcKernelの情報を
+返すようにした。
+[sysinfo]
+  totalram : rusage_global の total_memory
+  freeram : rusage_global の total_memory - usage_memory
+  mem_unit : 常に1
+[/proc/meminfo]
+  MemTotal : rusage_global の total_memory
+  MemFree : rusage_global の total_memory - usage_memory
+  SwapTotal : 常に0
+  SwapFree : 常に0
+  CommitLimit : rusage_global の total_memory - usage_memory
+  Committed_AS : rusage_global の usage_memory
+
+1. 本Issueで対応したsysinfo() と /proc/meminfo の値が想定どおりとなっていることを確認
+McKernelへのメモリ割り当てを 10G@0,10G@1 とした状態で下記プログラムを実行
+C1389T01: sysinfo() で取得される値が下記のとおりであることを確認
+  totalram : 20GiB * 0.95 以上、20GiB 未満であること
+  freeram : totralram * 0.95 以上、totalram 未満であること
+  mem_unit : 1 であること
+C1389T02: /proc/meminfo から取得される値が下記のとおりであることを確認
+  MemTotal : 20GiB * 0.95 以上、20GiB 未満であること
+  MemFree : MemTotal * 0.95 以上、MemTotal 未満であること
+  SwapTotal : 0 であること
+  SwapFree : 0 であること
+  CommitLimit : MemFreeと同値であること
+  Committed_AS : MemTotal - MemFree と同値であること
+
+2. 本Issueで対応したsysinfo() の項目を利用する以下のLTPを実行し、PASSすることを確認
+  - mtest01 -p80
+  - mtest01 -p80 -w
+  - mem01
+
+□ 実行手順
+$ make test
+
+McKernelのインストール先や、OSTEST, LTPの配置場所は、
+$HOME/.mck_test_config を参照している
+.mck_test_config は、McKernelをビルドした際に生成されるmck_test_config.sample ファイルを
+$HOMEにコピーし、適宜編集する
+
+□ 実行結果
+x86_64_result.log aarch64_result.log 参照。
+すべての項目をPASSしていることを確認。

+C1399T01:
+  1. struct robust_list_head のサイズよりも1大きい値をサイズとして指定して
+    set_robsut_list を呼び出し、EINVALで失敗することを確認
+  2. struct robust_list_head のサイズよりも1小さい値をサイズとして指定して
+    set_robsut_list を呼び出し、EINVALで失敗することを確認
+
+2. 以下のLTPを用いて既存のrobust_list機能に影響が無いことを確認
+  - set_robst_list01
+  - get_robst_list01
+
+□ 実行手順

+□ テスト内容
+1. 本修正ではmcexecにてSIGTSTP, SIGTTIN, SIGTTOU を補足しないようにする
+  修正を実施した。
+  上記のシグナルのデフォルト動作はプロセスの停止である。
+  それぞれのシグナルについて、以下を確認する。
+	- 実行中のMcKernelプロセスに通知した際、通知先のプロセスが停止する
+	- 停止されたプロセスに対してSIGCONTを通知することで、プロセスが再開できる
+
+C1425T01: SIGTSTP の動作を確認
+C1425T02: SIGTTIN の動作を確認
+C1425T03: SIGTTOU の動作を確認

-【Issue#929 動作確認】
-□ テスト内容
-1. mpirunで指定する-ppnと、mcexecで指定する-n の指定状況ごとに
-  想定どおりの動作となることを確認
-C929T01:
-  -ppn == -n の場合に、プログラムが実行され、mpirunが成功する
-
-C929T02:
-  -ppn > -n の場合に、プログラムの一部が実行され、mpirunが失敗する
-
-C929T03:
-  -ppn < -n の場合に、プログラムが実行されず、mpirunが失敗する
-
-C929T04:
-  -ppn が -n の整数倍である場合に、プログラムの一部が実行され、mpirunが失敗する
-
-C929T05:
-  -ppn と -n がMcKernelに割り当てたCPU数よりも大きい場合に、
-  プログラムが実行されず、mpirunが失敗する
-
-C929T06:
-  -ppn == -n での正常実行を20回連続で行った場合に、
-  プログラムが実行され、mpirunが成功する
-  また、mcctrlで管理しているpart_exec_list の要素数が5を超えない
-
-□ 実行手順
-$ make test
-
-McKernelのインストール先や、OSTEST, LTPの配置場所は、
-$HOME/.mck_test_config を参照している
-.mck_test_config は、McKernelをビルドした際に生成されるmck_test_config.sample ファイルを
-$HOMEにコピーし、適宜編集する
-
-□ 実行結果
-x86_64_result.log aarch64_result.log 参照。
-すべての項目をPASSしていることを確認。

Masamichi Takagi	40f8091fab	stack: grow on page fault The steps of the technique to replace stack with hugetlbfs map are as follows: (1) Prepare a hugetlbfs map with the size of rlim_cur (2) Copy the active region of the stack to the hugetlbfs map. The range to copy is determined by reading /proc/[pid]/maps. (3) Replace the stack map with the hugetlbfs map The step (2) tries to copy a huge region if McKernel doesn't grow the stack at run-time.
