2018-10-11cxgb4: fix thermal configuration dependenciesArnd Bergmann4-11/+10
With CONFIG_THERMAL=m, we get a build error: drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c: In function 'cxgb4_thermal_get_trip_type': drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c:48:11: error: 'struct adapter' has no member named 'ch_thermal' Once that is fixed by using IS_ENABLED() checks, we get a link error against the thermal subsystem when cxgb4 is built-in: drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_init': cxgb4_thermal.c:(.text+0x180): undefined reference to `thermal_zone_device_register' drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_remove': cxgb4_thermal.c:(.text+0x1e0): undefined reference to `thermal_zone_device_unregister' Finally, since CONFIG_THERMAL can be =m, the Makefile fails to pick up the extra file into built-in.a, and we get another link failure against the cxgb4_thermal_init/cxgb4_thermal_remove files, so the Makefile has to be adapted as well to work for both CONFIG_THERMAL=y and =m.

2018-10-05net: cxgb3_main: fix a missing-check bugWenwen Wang1-0/+17
In cxgb_extension_ioctl(), the command of the ioctl is firstly copied from the user-space buffer 'useraddr' to 'cmd' and checked through the switch statement. If the command is not as expected, an error code EOPNOTSUPP is returned. In the following execution, i.e., the cases of the switch statement, the whole buffer of 'useraddr' is copied again to a specific data structure, according to what kind of command is requested. However, after the second copy, there is no re-check on the newly-copied command. Given that the buffer 'useraddr' is in the user space, a malicious user can race to change the command between the two copies. By doing so, the attacker can supply malicious data to the kernel and cause undefined behavior. This patch adds a re-check in each case of the switch statement if there is a second copy in that case, to re-check whether the command obtained in the second copy is the same as the one in the first copy. If not, an error code EINVAL is returned. Signed-off-by: Wenwen Wang <wang6495@umn.edu> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-08-07cxgb4: mk_act_open_req() buggers ->{local, peer}_ip on big-endian hostsAl Viro1-4/+2
Unlike fs.val.lport and fs.val.fport, cxgb4_process_flow_match() sets fs.val.{l,f}ip to net-endian values without conversion - they come straight from flow_dissector_key_ipv4_addrs ->dst and ->src resp. So the assignment in mk_act_open_req() ought to be a straight copy. As far as I know, T4 PCIe cards do exist, so it's not as if that thing could only be found on little-endian systems...

2018-07-18net: cxgb3_main: fix potential Spectre v1Gustavo A. R. Silva1-0/+2
t.qset_idx can be indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/net/ethernet/chelsio/cxgb3/cxgb3_main.c:2286 cxgb_extension_ioctl() warn: potential spectre issue 'adapter->msix_info' Fix this by sanitizing t.qset_idx before using it to index adapter->msix_info Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].
