Perilaku kunci dan interaksi NFSv4 ACL - Cloud Parallel File Storage

Topik ini memperkenalkan fitur daftar kontrol akses (ACL) NFSv4, termasuk urutan dan pewarisan izin akses, pengurutan dan penggabungan entri kontrol akses (ACE), serta migrasi ACL.

Urutan izin akses

ACE dalam sebuah ACL dievaluasi berdasarkan urutan kemunculannya.

ACE mendukung tipe Allow dan Deny. ACE bertipe Deny dapat ditempatkan di posisi mana pun dalam daftar. Misalnya, jika sebuah ACL memiliki dua ACE—group:adminis:rwxc dan group:adminis:r---—urutannya menentukan apakah pengguna adminis2 memiliki izin baca. Saat mengatur ACL, perhatikan dengan cermat posisi setiap ACE.

Sebagai contoh, jika izin untuk pengguna adminis2 pada direktori dir4 diatur sebagai berikut, pengguna tersebut memiliki semua izin pada direktori tersebut.

#NFSv4 ACL
#owner:root
#group:root
group:adminis2:rwxc:allow
 (X)READ/LIST (X)WRITE/CREATE (X)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (X)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

group:adminis2:r---:deny
 (X)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (-)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

 (-)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (X)CHOWN        (-)EXEC/SEARCH (X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

special:group@:----:allow
 (-)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (-)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

special:everyone@:----:allow
 (-)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (-)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

Jika izin untuk pengguna adminis2 pada direktori dir4 diatur sebagai berikut, pengguna tersebut tidak memiliki izin baca.

#NFSv4 ACL
#owner:root
#group:root
group:adminis2:r---:deny
 (X)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (-)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

group:adminis2:rwxc:allow
 (X)READ/LIST (X)WRITE/CREATE (X)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (X)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

 (-)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (X)CHOWN        (-)EXEC/SEARCH (X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

special:group@:----:allow
 (-)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (-)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

 (-)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (-)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

Pengurutan dan penggabungan ACE

Saat Anda menambahkan ACE baru untuk pengguna, ACE tersebut tidak digabungkan dengan ACE yang sudah ada.

Sebagai contoh, pengguna 1001 yang termasuk dalam kelompok players memiliki izin akses berikut. Jika Anda menambahkan ACE yang memberikan izin akses kepada kelompok players, ACE baru tersebut tidak digabungkan dengan ACE yang sudah ada.

Verifikasi bahwa izin baru telah berlaku.

Jalankan perintah

sudo su player -c 'echo 456 >> file'

sudo su player -c 'cat file'

Contoh keluaran
```
123
456
```

Pewarisan izin akses

Untuk direktori dir5, pemilik diberikan izin tulis, kelompok diberikan izin baca, dan pengguna lain ditolak aksesnya.

Berikan izin baca dan tulis yang dapat diwariskan kepada pengguna player.

Konfigurasikan izin baca dan tulis untuk pengguna player dan simpan aturan ke dalam file teks, misalnya acl2.txt.

#NFSv4 ACL
#owner:root
#group:root
user:player:rwx-:allow:DirInherit
 (X)READ/LIST (X)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

user:player:rwx-:allow:FileInherit
 (X)READ/LIST (X)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

Terapkan aturan dari acl2.txt ke direktori dir5.
```
mmputacl -i ~/acl2.txt dir5
```

File atau subdirektori yang dibuat di direktori dir5 secara otomatis mewarisi ACE tersebut.

Masuk ke direktori dir5.
```
cd  dir5
```
Buat file file.
```
touch file
```

Konfirmasi bahwa file file secara otomatis mewarisi izin ACE dari direktori dir5.

Jalankan perintah
```
mmgetacl file
```

Contoh keluaran

#NFSv4 ACL
#owner:root
#group:root
user:player:rwx-:allow:Inherited
 (X)READ/LIST (X)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

Buat direktori subdir.
```
mkdir subdir
```

Konfirmasi bahwa subdirektori subdir secara otomatis mewarisi izin ACE dari direktori dir5.

Jalankan perintah
```
mmgetacl subdir
```

Contoh keluaran

#NFSv4 ACL
#owner:root
#group:root
user:player:rwx-:allow:DirInherit:Inherited
 (X)READ/LIST (X)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

user:player:rwx-:allow:FileInherit:InheritOnly:Inherited
 (X)READ/LIST (X)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

File atau subdirektori yang Anda buat di subdirektori subdir juga secara otomatis mewarisi ACE tersebut.

Buat direktori subdir/subdir2.
```
mkdir subdir/subdir2
```

Konfirmasi bahwa direktori subdir/subdir2 secara otomatis mewarisi ACE dari subdirektori subdir.

Jalankan perintah
```
mmgetacl subdir/subdir2
```

Contoh keluaran

#NFSv4 ACL
#owner:root
#group:root
user:player:rwx-:allow:DirInherit:Inherited
 (X)READ/LIST (X)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

user:player:rwx-:allow:FileInherit:InheritOnly:Inherited
 (X)READ/LIST (X)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

Buat file subdir/file2.
```
touch subdir/file2
```

Konfirmasi bahwa file subdir/file2 secara otomatis mewarisi ACE dari subdirektori subdir.

Jalankan perintah
```
mmgetacl subdir/file2
```

Contoh keluaran

#NFSv4 ACL
#owner:root
#group:root
user:player:rwx-:allow:Inherited
 (X)READ/LIST (X)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

Flag InheritOnly menunjukkan bahwa ACE tersebut tidak digunakan untuk pemeriksaan izin pada direktori saat ini, tetapi diwariskan oleh objek turunannya.

Catatan

Konfigurasikan DirInherit dan FileInherit dalam ACE terpisah. Jika tidak, kesalahan Combining FileInherit and DirInherit makes the mask ambiguous akan dikembalikan.
Saat menggunakan inherit only, ACE tersebut tidak digunakan untuk pemeriksaan izin. Anda harus mengonfigurasi izin baca (r) dan eksekusi (x) pada direktori induk. Jika tidak, pengguna player tidak dapat mengakses subdirektori tersebut.

Keluaran

Anda tidak dapat menggunakan atribut tambahan (extended attributes) untuk mengekspor ACL NFSv4.

Migrasi

Anda dapat menggunakan alat seperti cp untuk melakukan migrasi ACL NFSv4.

Alibaba Cloud Cloud Parallel File Storage (CPFS) memungkinkan Anda menggunakan alat cp, tar, dan rsync untuk melakukan migrasi ACL NFSv4. Untuk informasi selengkapnya, lihat How to preserve NFS v4 ACLs via extended attributes when copying file.

Dalam contoh berikut, perintah cp --preserve=xattr file2 file5 menyalin ACL saat menyalin file2 ke file5.

Catatan

Alat rsync mungkin gagal melakukan migrasi ACL NFSv4 jika versinya lebih lama dari 3.1.2.

Lakukan migrasi ACL file2 ke file5.

cp --preserve=xattr newsub/file2 newsub/file5

Lihat ACL file2.

Jalankan perintah
```
mmgetacl newsub/file2
```
