Title
calipso: Don't call calipso functions for AF_INET sk.
Summary
In the Linux kernel, the following vulnerability has been resolved: calipso: Don't call calipso functions for AF_INET sk. syzkaller reported a null-ptr-deref in txopt_get(). [0] The offset 0x70 was of struct ipv6_txoptions in struct ipv6_pinfo, so struct ipv6_pinfo was NULL there. However, this never happens for IPv6 sockets as inet_sk(sk)->pinet6 is always set in inet6_create(), meaning the socket was not IPv6 one. The root cause is missing validation in netlbl_conn_setattr(). netlbl_conn_setattr() switches branches based on struct sockaddr.sa_family, which is passed from userspace. However, netlbl_conn_setattr() does not check if the address family matches the socket. The syzkaller must have called connect() for an IPv6 address on an IPv4 socket. We have a proper validation in tcp_v[46]_connect(), but security_socket_connect() is called in the earlier stage. Let's copy the validation to netlbl_conn_setattr(). [0]: Oops: general protection fault, probably for non-canonical address 0xdffffc000000000e: 0000 [#1] PREEMPT SMP KASAN NOPTI KASAN: null-ptr-deref in range [0x0000000000000070-0x0000000000000077] CPU: 2 UID: 0 PID: 12928 Comm: syz.9.1677 Not tainted 6.12.0 #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 RIP: 0010:txopt_get include/net/ipv6.h:390 [inline] RIP: 0010: Code: 02 00 00 49 8b ac 24 f8 02 00 00 e8 84 69 2a fd e8 ff 00 16 fd 48 8d 7d 70 48 b8 00 00 00 00 00 fc ff df 48 89 fa 48 c1 ea 03 <80> 3c 02 00 0f 85 53 02 00 00 48 8b 6d 70 48 85 ed 0f 84 ab 01 00 RSP: 0018:ffff88811b8afc48 EFLAGS: 00010212 RAX: dffffc0000000000 RBX: 1ffff11023715f8a RCX: ffffffff841ab00c RDX: 000000000000000e RSI: ffffc90007d9e000 RDI: 0000000000000070 RBP: 0000000000000000 R08: ffffed1023715f9d R09: ffffed1023715f9e R10: ffffed1023715f9d R11: 0000000000000003 R12: ffff888123075f00 R13: ffff88810245bd80 R14: ffff888113646780 R15: ffff888100578a80 FS: 00007f9019bd7640(0000) GS:ffff8882d2d00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f901b927bac CR3: 0000000104788003 CR4: 0000000000770ef0 PKRU: 80000000 Call Trace: <TASK> calipso_sock_setattr+0x56/0x80 net/netlabel/netlabel_calipso.c:557 netlbl_conn_setattr+0x10c/0x280 net/netlabel/netlabel_kapi.c:1177 selinux_netlbl_socket_connect_helper+0xd3/0x1b0 security/selinux/netlabel.c:569 selinux_netlbl_socket_connect_locked security/selinux/netlabel.c:597 [inline] selinux_netlbl_socket_connect+0xb6/0x100 security/selinux/netlabel.c:615 selinux_socket_connect+0x5f/0x80 security/selinux/hooks.c:4931 security_socket_connect+0x50/0xa0 security/security.c:4598 __sys_connect_file+0xa4/0x190 net/socket.c:2067 __sys_connect+0x12c/0x170 net/socket.c:2088 __do_sys_connect net/socket.c:2098 [inline] __se_sys_connect net/socket.c:2095 [inline] __x64_sys_connect+0x73/0xb0 net/socket.c:2095 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xaa/0x1b0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7f901b61a12d Code: 02 b8 ff ff ff ff c3 66 0f 1f 44 00 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48 RSP: 002b:00007f9019bd6fa8 EFLAGS: 00000246 ORIG_RAX: 000000000000002a RAX: ffffffffffffffda RBX: 00007f901b925fa0 RCX: 00007f901b61a12d RDX: 000000000000001c RSI: 0000200000000140 RDI: 0000000000000003 RBP: 00007f901b701505 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000 R13: 0000000000000000 R14: 00007f901b5b62a0 R15: 00007f9019bb7000 </TASK> Modules linked in:

[0] El desplazamiento 0x70 correspond\u00eda a struct ipv6_txoptions en struct ipv6_pinfo, por lo que struct ipv6_pinfo era nulo. Sin embargo, esto nunca ocurre con sockets IPv6, ya que inet_sk(sk)-\u0026gt;pinet6 siempre se configura en inet6_create(), lo que significa que el socket no era IPv6. La causa principal es la falta de validaci\u00f3n en netlbl_conn_setattr(). netlbl_conn_setattr() cambia de rama seg\u00fan struct sockaddr.sa_family, que se pasa desde el espacio de usuario. Sin embargo, netlbl_conn_setattr() no comprueba si la familia de direcciones coincide con el socket. El syzkaller debe haber llamado a connect() para una direcci\u00f3n IPv6 en un socket IPv4. Tenemos una validaci\u00f3n correcta en tcp_v[46]_connect(), pero security_socket_connect() se llama en la etapa anterior. Copiemos la validaci\u00f3n a netlbl_conn_setattr().
