2019-05-25net/mlx5e: Fix calling wrong function to get inner vlan key and maskJianbo Liu1-1/+1
[ Upstream commit 12d5cbf89a6599f6bbd7b373dba0e74b5bd9c505 ] When flow_rule_match_XYZ() functions were first introduced, flow_rule_match_cvlan() for inner vlan is missing. In mlx5_core driver, to get inner vlan key and mask, flow_rule_match_vlan() is just called, which is wrong because it obtains outer vlan information by FLOW_DISSECTOR_KEY_VLAN. This commit fixes this by changing to call flow_rule_match_cvlan() after it's added.

2019-05-25mlxsw: core: Prevent reading unsupported slave address from SFP EEPROMVadim Pasternak1-2/+16
[ Upstream commit f1436c8036fa3632b2ee78841cf5184b7ef0ad87 ] Prevent reading unsupported slave address from SFP EEPROM by testing Diagnostic Monitoring Type byte in EEPROM. Read only page zero of EEPROM, in case this byte is zero. If some SFP transceiver does not support Digital Optical Monitoring (DOM), reading SFP EEPROM slave address 0x51 could return an error. Availability of DOM support is verified by reading from zero page Diagnostic Monitoring Type byte describing how diagnostic monitoring is implemented by transceiver. If bit 6 of this byte is set, it indicates that digital diagnostic monitoring has been implemented. Otherwise it is not and transceiver could fail to reply to transaction for slave address 0x51 [1010001X (A2h)], which is used to access measurements page. Such issue has been observed when reading cable MCP2M00-xxxx, MCP7F00-xxxx, and few others.

2019-05-16tuntap: synchronize through tfiles array instead of tun->numqueuesJason Wang1-1/+6
[ Upstream commit 9871a9e47a2646fe30ae7fd2e67668a8d30912f6 ] When a queue(tfile) is detached through __tun_detach(), we move the last enabled tfile to the position where detached one sit but don't NULL out last position. We expect to synchronize the datapath through tun->numqueues. Unfortunately, this won't work since we're lacking sufficient mechanism to order or synchronize the access to tun->numqueues. To fix this, NULL out the last position during detaching and check RCU protected tfile against NULL instead of checking tun->numqueues in datapath.

2019-05-16bonding: fix arp_validate toggling in active-backup modeJarod Wilson1-7/+0
[ Upstream commit a9b8a2b39ce65df45687cf9ef648885c2a99fe75 ] There's currently a problem with toggling arp_validate on and off with an active-backup bond. At the moment, you can start up a bond, like so: modprobe bonding mode=1 arp_interval=100 arp_validate=0 arp_ip_targets=192.168.1.1 ip link set bond0 down echo "ens4f0" > /sys/class/net/bond0/bonding/slaves echo "ens4f1" > /sys/class/net/bond0/bonding/slaves ip link set bond0 up ip addr add 192.168.1.2/24 dev bond0 Pings to 192.168.1.1 work just fine. Now turn on arp_validate: echo 1 > /sys/class/net/bond0/bonding/arp_validate Pings to 192.168.1.1 continue to work just fine. Now when you go to turn arp_validate off again, the link falls flat on it's face: echo 0 > /sys/class/net/bond0/bonding/arp_validate dmesg ... [133191.911987] bond0: Setting arp_validate to none (0) [133194.257793] bond0: bond_should_notify_peers: slave ens4f0 [133194.258031] bond0: link status definitely down for interface ens4f0, disabling it [133194.259000] bond0: making interface ens4f1 the new active one [133197.330130] bond0: link status definitely down for interface ens4f1, disabling it [133197.331191] bond0: now running without any active interface! The problem lies in bond_options.c, where passing in arp_validate=0 results in bond->recv_probe getting set to NULL. This flies directly in the face of commit 3fe68df97c7f, which says we need to set recv_probe = bond_arp_recv, even if we're not using arp_validate. Said commit fixed this in bond_option_arp_interval_set, but missed that we can get to that same state in bond_option_arp_validate_set as well. One solution would be to universally set recv_probe = bond_arp_recv here as well, but I don't think bond_option_arp_validate_set has any business touching recv_probe at all, and that should be left to the arp_interval code, so we can just make things much tidier here.

2019-05-16mwl8k: Fix rate_idx underflowPetr Štetiar1-4/+9
commit 6b583201fa219b7b1b6aebd8966c8fd9357ef9f4 upstream. It was reported on OpenWrt bug tracking system[1], that several users are affected by the endless reboot of their routers if they configure 5GHz interface with channel 44 or 48. The reboot loop is caused by the following excessive number of WARN_ON messages: WARNING: CPU: 0 PID: 0 at backports-4.19.23-1/net/mac80211/rx.c:4516 ieee80211_rx_napi+0x1fc/0xa54 [mac80211] as the messages are being correctly emitted by the following guard: case RX_ENC_LEGACY: if (WARN_ON(status->rate_idx >= sband->n_bitrates)) as the rate_idx is in this case erroneously set to 251 (0xfb). This fix simply converts previously used magic number to proper constant and guards against substraction which is leading to the currently observed underflow. 1. https://bugs.openwrt.org/index.php?do=details&task_id=2218 Fixes: 854783444bab ("mwl8k: properly set receive status rate index on 5 GHz receive") Cc: <stable@vger.kernel.org> Tested-by: Eubert Bao <bunnier@gmail.com> Reported-by: Eubert Bao <bunnier@gmail.com> Signed-off-by: Petr Štetiar <ynezz@true.cz> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

A simple reproduction case is to run this on QCA6174A / WLAN.RM.4.4.1-00132-QCARMSWP-1, which happens to be a way to b0rk the firmware: dd if=/sys/kernel/debug/ieee80211/phy0/ath10k/mem_value bs=4K count=1 of=/dev/null (NB: simulated firmware crashes, via debugfs, don't trigger firmware dumps.) The fix is to move the crash-dump into a workqueue context, and avoid relying on 'data_lock' for most mutual exclusion. We only keep using it here for protecting 'fw_crash_counter', while the rest of the coredump buffers are protected by a new 'dump_mutex'. I've tested the above with simulated firmware crashes (debugfs 'reset' file), real firmware crashes (the 'dd' command above), and a variety of reboot and suspend/resume configurations on QCA6174A.

We don't check for the validity of the lengths in the packet received from the firmware. If the MPDU length received in the rx descriptor is too short to contain the header length and the crypt length together, we may end up trying to copy a negative number of bytes (headlen - hdrlen < 0) which will underflow and cause us to try to copy a huge amount of data.

This way, slhc_free() accepts what slhc_init() returns, whether that is an error or not. In particular, the pattern in sl_alloc_bufs() is slcomp = slhc_init(16, 16); ... slhc_free(slcomp); for the error handling path, and rather than complicate that code, just make it ok to always free what was returned by the init function.

2019-04-25mwifiex: Make resume actually do something useful again on SDIO cardsDouglas Anderson1-1/+1
The commit fc3a2fcaa1ba ("mwifiex: use atomic bitops to represent adapter status variables") had a fairly straightforward bug in it. It contained this bit of diff: - if (!adapter->is_suspended) { + if (test_bit(MWIFIEX_IS_SUSPENDED, &adapter->work_flags)) { As you can see the patch missed the "!" when converting to the atomic bitops. This meant that the resume hasn't done anything at all since that commit landed and suspend/resume for mwifiex SDIO cards has been totally broken. After fixing this mwifiex suspend/resume appears to work again, at least with the simple testing I've done.

2019-04-23net: stmmac: move stmmac_check_ether_addr() to driver probeVinod Koul1-2/+2
stmmac_check_ether_addr() checks the MAC address and assigns one in driver open(). In many cases when we create slave netdevice, the dev addr is inherited from master but the master dev addr maybe NULL at that time, so move this call to driver probe so that address is always valid.
