現象:
PHCO_36034:
(SR:8606426927 CR:JAGaf86408)
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_36034:
(SR:8606426927 CR:JAGaf86408)
現在のワークディレクトリが読み取り不能な場合、その絶対パスに対して
"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が表示されていました。
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 not found
このように、"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:
rm(1)を修正しました。

Symptoms:
PHCO_36034:
( SR:8606426927 CR:JAGaf86408 )
rm(1) -r fails to remove directories specified with
absolute path when current working directory is unreadable.
PHCO_32607:
( SR:8606380965 CR:JAGaf41183 )
rm -r dumps core under certain circumstances.
Defect Description:
PHCO_36034:
( SR:8606426927 CR:JAGaf86408 )
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 not found
The error message "Cannot remove mountable directory" is
misleading.
Resolution:
rm(1) is fixed to resolve the problem.
PHCO_32607:
( SR:8606380965 CR:JAGaf41183 )
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 << !!

mkdir: cannot create xxxxxxxxxxxxxxxxxxxxxxxx....

Resolution:
While creating the absolute path name,
the available memory space in the buffer
is now being calculated correctly.
Enhancement:
No
