2020-03-12tcp: Forbid to bind more than one sockets haveing SO_REUSEADDR and ↵Kuniyuki Iwashima1-3/+9
SO_REUSEPORT per EUID. If there is no TCP_LISTEN socket on a ephemeral port, we can bind multiple sockets having SO_REUSEADDR to the same port. Then if all sockets bound to the port have also SO_REUSEPORT enabled and have the same EUID, all of them can be listened. This is not safe. Let's say, an application has root privilege and binds sockets to an ephemeral port with both of SO_REUSEADDR and SO_REUSEPORT. When none of sockets is not listened yet, a malicious user can use sudo, exhaust ephemeral ports, and bind sockets to the same ephemeral port, so he or she can call listen and steal the port. To prevent this issue, we must not bind more than one sockets that have the same EUID and both of SO_REUSEADDR and SO_REUSEPORT. On the other hand, if the sockets have different EUIDs, the issue above does not occur. After sockets with different EUIDs are bound to the same port and one of them is listened, no more socket can be listened. This is because the condition below is evaluated true and listen() for the second socket fails. } else if (!reuseport_ok || !reuseport || !sk2->sk_reuseport || rcu_access_pointer(sk->sk_reuseport_cb) || (sk2->sk_state != TCP_TIME_WAIT && !uid_eq(uid, sock_i_uid(sk2)))) { if (inet_rcv_saddr_equal(sk, sk2, true)) break; } Therefore, on the same port, we cannot do listen() for multiple sockets with different EUIDs and any other listen syscalls fail, so the problem does not happen. In this case, we can still call connect() for other sockets that cannot be listened, so we have to succeed to call bind() in order to fully utilize 4-tuples. Summarizing the above, we should be able to bind only one socket having SO_REUSEADDR and SO_REUSEPORT per EUID. Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.co.jp> Signed-off-by: David S.

2020-03-12tcp: bind(0) remove the SO_REUSEADDR restriction when ephemeral ports are ↵Kuniyuki Iwashima4-1/+28
exhausted. Commit aacd9289af8b82f5fb01bcdd53d0e3406d1333c7 ("tcp: bind() use stronger condition for bind_conflict") introduced a restriction to forbid to bind SO_REUSEADDR enabled sockets to the same (addr, port) tuple in order to assign ports dispersedly so that we can connect to the same remote host. The change results in accelerating port depletion so that we fail to bind sockets to the same local port even if we want to connect to the different remote hosts. You can reproduce this issue by following instructions below. 1. # sysctl -w net.ipv4.ip_local_port_range="32768 32768" 2. set SO_REUSEADDR to two sockets. 3. bind two sockets to (localhost, 0) and the latter fails. Therefore, when ephemeral ports are exhausted, bind(0) should fallback to the legacy behaviour to enable the SO_REUSEADDR option and make it possible to connect to different remote (addr, port) tuples. This patch allows us to bind SO_REUSEADDR enabled sockets to the same (addr, port) only when net.ipv4.ip_autobind_reuse is set 1 and all ephemeral ports are exhausted. This also allows connect() and listen() to share ports in the following way and may break some applications. So the ip_autobind_reuse is 0 by default and disables the feature. 1. setsockopt(sk1, SO_REUSEADDR) 2. setsockopt(sk2, SO_REUSEADDR) 3. bind(sk1, saddr, 0) 4. bind(sk2, saddr, 0) 5. connect(sk1, daddr) 6. listen(sk2) If it is set 1, we can fully utilize the 4-tuples, but we should use IP_BIND_ADDRESS_NO_PORT for bind()+connect() as possible. The notable thing is that if all sockets bound to the same port have both SO_REUSEADDR and SO_REUSEPORT enabled, we can bind sockets to an ephemeral port and also do listen().

Jakub Kicinski says: ==================== ethtool: consolidate irq coalescing - part 4 Convert more drivers following the groundwork laid in a recent patch set [1] and continued in [2], [3]. The aim of the effort is to consolidate irq coalescing parameter validation in the core. This set converts 15 drivers in drivers/net/ethernet - remaining Intel drivers, Freescale/NXP, and others. 2 more conversion sets to come.

2020-03-12cdc_ncm: Implement the 32-bit version of NCM Transfer BlockAlexander Bersenev3-94/+340
The NCM specification defines two formats of transfer blocks: with 16-bit fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is implemented. This patch adds the support of NTB-32. The motivation behind this is that some devices such as E5785 or E5885 from the current generation of Huawei LTE routers do not support NTB-16. The previous generations of Huawei devices are also use NTB-32 by default. Also this patch enables NTB-32 by default for Huawei devices. During the 2019 ValdikSS made five attempts to contact Huawei to add the NTB-16 support to their router firmware, but they were unsuccessful.

2020-03-12bareudp: Fixed bareudp receive handlingMartin Varghese1-0/+6
Reverted commit "2baecda bareudp: remove unnecessary udp_encap_enable() in bareudp_socket_create()" An explicit call to udp_encap_enable is needed as the setup_udp_tunnel_sock does not call udp_encap_enable if the if the socket is of type v6. Bareudp device uses v6 socket to receive v4 & v6 traffic CC: Taehee Yoo <ap420073@gmail.com> Fixes: 2baecda37f4e ("bareudp: remove unnecessary udp_encap_enable() in bareudp_socket_create()") Signed-off-by: Martin Varghese <martin.varghese@nokia.com> Signed-off-by: David S.

2020-03-11ftgmac100: Remove redundant judgementtangbin1-3/+0
In this function, ftgmac100_probe() can be triggered only if the platform_device and platform_driver matches, so the judgement at the beginning is redundant. Signed-off-by: tangbin <tangbin@cmss.chinamobile.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-11Merge branch 'ethtool-consolidate-irq-coalescing-part-3'David S. Miller16-18/+58
Jakub Kicinski says: ==================== ethtool: consolidate irq coalescing - part 3 Convert more drivers following the groundwork laid in a recent patch set [1] and continued in [2]. The aim of the effort is to consolidate irq coalescing parameter validation in the core. This set converts 15 drivers in drivers/net/ethernet. 3 more conversion sets to come. None of the drivers here checked all unsupported parameters.
