2018-10-19cxgb4: fix the error path of cxgb4_uld_register()Ganesh Goudar2-36/+12
On multi adapter setup if the uld registration fails even on one adapter, the allocated resources for the uld on all the adapters are freed, rendering the functioning adapters unusable. This commit fixes the issue by freeing the allocated resources only for the failed adapter. Signed-off-by: Ganesh Goudar <ganeshgr@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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>

We were returning DUPLEX_UNKNOWN in get_link_ksettings() when the link was down. Unfortunately, this causes a problem when "ethtool -s autoneg on" is issued for a link which is down because the ethtool code first reads the settings and then reapplies them with only the changes provided on the command line. Which results in us diving into set_link_ksettings() with DUPLEX_UNKNOWN which is not DUPLEX_FULL, so set_link_ksettings() throws an -EINVAL error. do not return DUPLEX_UNKNOWN to fix the issue.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== L2 Fwd Offload & 10GbE Intel Driver Updates 2018-07-09 This patch series is meant to allow support for the L2 forward offload, aka MACVLAN offload without the need for using ndo_select_queue. The existing solution currently requires that we use ndo_select_queue in the transmit path if we want to associate specific Tx queues with a given MACVLAN interface. In order to get away from this we need to repurpose the tc_to_txq array and XPS pointer for the MACVLAN interface and use those as a means of accessing the queues on the lower device. As a result we cannot offload a device that is configured as multiqueue, however it doesn't really make sense to configure a macvlan interfaced as being multiqueue anyway since it doesn't really have a qdisc of its own in the first place. The big changes in this set are: Allow lower device to update tc_to_txq and XPS map of offloaded MACVLAN Disable XPS for single queue devices Replace accel_priv with sb_dev in ndo_select_queue Add sb_dev parameter to fallback function for ndo_select_queue Consolidated ndo_select_queue functions that appeared to be duplicates ==================== Signed-off-by: David S.
