パッチ名: PHCO_35369
パッチ摘要: s700_800 11.23 rm(1)累積パッチ
作成日: 06/10/05
公開日: 07/01/22
ハードウェアプラットフォームおよびOSリリース:
s700: 11.23
s800: 11.23
現象:
PHCO_35369:
(SR:8606424905 CR:JAGaf84425)
現在のワークディレクトリが読み取り不能な場合、"rm(1) -r"が、絶対パスで
指定されたディレクトリを削除できません。
問題点の説明:
PHCO_35369:
(SR:8606424905 CR:JAGaf84425)
現在のワークディレクトリが読み取り不能な場合、ある絶対パスに対して
"rm(1) -r"を実行しようとすると、rm(1)が異常終了し、"Cannot remove
mountable directory"というエラーメッセージを表示します。
問題の再現手順:
# whoami
root
# mkdir /var/tmp/to_be_removed
# chown lp:lp /var/tmp/to_be_removed
# mkdir /var/tmp/restricted; chmod 700 /var/tmp/restricted
# cd /var/tmp/restricted; su lp
# whoami
lp
# rm -r /var/tmp/to_be_removed
rm: directory /var/tmp/to_be_removed not removed.
Cannot remove mountable directory
# ls -d /var/tmp/to_be_removed
/var/tmp/to_be_removed
# rmdir /var/tmp/to_be_removed
# ls -d /var/tmp/to_be_removed
/var/tmp/to_be_removed not found
"Cannot remove mountable directory"という紛らわしいエラーメッセージが
表示されます。
解決方法:
指定されたディレクトリに対してrm(1)操作を行う場合は、その前に、現在の
ワークディレクトリが読み取り可能かチェックするようにrm(1)のコードを修
正しました。現在のワークディレクトリが読み取り不能な場合は、現在のワー
クディレクトリを"/"に変更してから、指定された絶対パスに対してrm操作を
行います。
また、エラーメッセージも修正しました。

Symptoms:
PHCO_35369:
( SR:8606424905 CR:JAGaf84425 )
rm(1) -r fails to remove directories specified with
absolute path when current working directory is unreadable.
PHCO_31637:
( SR:8606363161 CR:JAGaf23824 )
rm -r dumps core under certain circumstances.
Defect Description:
PHCO_35369:
( SR:8606424905 CR:JAGaf84425 )
When rm(1) -r is attempted on a absolute path from a
unreadable current working directory rm(1) aborts and
throws error message as "Cannot remove mountable directory."
It can be reproduced as follows:-
# whoami
root
# mkdir /var/tmp/to_be_removed
# chown lp:lp /var/tmp/to_be_removed
# mkdir /var/tmp/restricted; chmod 700 /var/tmp/restricted
# cd /var/tmp/restricted; su lp
# whoami
lp
# rm -r /var/tmp/to_be_removed
rm: directory /var/tmp/to_be_removed not removed.
Cannot remove mountable directory
# ls -d /var/tmp/to_be_removed
/var/tmp/to_be_removed
# rmdir /var/tmp/to_be_removed
# ls -d /var/tmp/to_be_removed
/var/tmp/to_be_removed not found
The error message "Cannot remove mountable directory" is
misleading.
Resolution:
This defect in rm(1) is fixed by checking if current working
directory is readable before attempting the rm(1) operation
on specified directory. If current working directory is
unreadable then, current working directory is changed to "/"
before attempting rm operation on the specified absolute
path.
The error message is changed to give better information.
PHCO_31637:
( SR:8606363161 CR:JAGaf23824 )
When rm -r is invoked on some directory, under
certain circumstances, rm(1) dumps core. This is
happening while creating the absolute path name
of the directory to be removed. While creating
the absolute path name, the available memory space
in the buffer was being calculated incorrectly
resulting in a array bound write and core dump.
Problem Reproduction:
# cat test.sh
#!/bin/sh
cd /tmp
while read a
do
mkdir $a
/usr/bin/rm -r $a
mkdir $a
cd $a
done << !!

./test.sh[8]: 12269 Memory fault(coredump)
mkdir: cannot create xxxxxxxxxxxxxxxxxxxxxxxx....
File exists
Resolution:
While creating the absolute path name,
the available memory space in the buffer
is now being calculated correctly.
Enhancement:
No
