2016-10-19openvswitch: remove unnecessary EXPORT_SYMBOLsJiri Benc1-1/+0

2016-10-19bpf: Detect identical PTR_TO_MAP_VALUE_OR_NULL registersThomas Graf3-17/+118
A BPF program is required to check the return register of a map_elem_lookup() call before accessing memory. The verifier keeps track of this by converting the type of the result register from PTR_TO_MAP_VALUE_OR_NULL to PTR_TO_MAP_VALUE after a conditional jump ensures safety. This check is currently exclusively performed for the result register 0. In the event the compiler reorders instructions, BPF_MOV64_REG instructions may be moved before the conditional jump which causes them to keep their type PTR_TO_MAP_VALUE_OR_NULL to which the verifier objects when the register is accessed: 0: (b7) r1 = 10 1: (7b) *(u64 *)(r10 -8) = r1 2: (bf) r2 = r10 3: (07) r2 += -8 4: (18) r1 = 0x59c00000 6: (85) call 1 7: (bf) r4 = r0 8: (15) if r0 == 0x0 goto pc+1 R0=map_value(ks=8,vs=8) R4=map_value_or_null(ks=8,vs=8) R10=fp 9: (7a) *(u64 *)(r4 +0) = 0 R4 invalid mem access 'map_value_or_null' This commit extends the verifier to keep track of all identical PTR_TO_MAP_VALUE_OR_NULL registers after a map_elem_lookup() by assigning them an ID and then marking them all when the conditional jump is observed.

Writes to u16 has a special handling on 3 PXA platforms, where the hardware wiring forces these writes to be u32 aligned. This patch isolates this handling for PXA platforms as before, but enables this "workaround" to be set up dynamically, which will be the case in device-tree build types.

2016-10-18net: phy: leds: add support for led triggers on phy link state changeZach Brown7-0/+214
Create an option CONFIG_LED_TRIGGER_PHY (default n), which will create a set of led triggers for each instantiated PHY device. There is one LED trigger per link-speed, per-phy. The triggers are registered during phy_attach and unregistered during phy_detach. This allows for a user to configure their system to allow a set of LEDs not controlled by the phy to represent link state changes on the phy. LEDS controlled by the phy are unaffected. For example, we have a board where some of the leds in the RJ45 socket are controlled by the phy, but others are not. Using the triggers provided by this patch the leds not controlled by the phy can be configured to show the current speed of the ethernet connection. The leds controlled by the phy are unaffected.

2016-10-18net: Introduce new api for walking upper and lower devicesDavid Ahern2-0/+172
This patch introduces netdev_walk_all_upper_dev_rcu, netdev_walk_all_lower_dev and netdev_walk_all_lower_dev_rcu. These functions recursively walk the adj_list of devices to determine all upper and lower devices. The functions take a callback function that is invoked for each device in the list. If the callback returns non-0, the walk is terminated and the functions return that code back to callers. v3 - simplified netdev_has_upper_dev_all_rcu and __netdev_has_upper_dev and removed typecast as suggested by Stephen v2 - fixed definition of netdev_next_lower_dev_rcu to mirror the upper_dev version.

2016-10-18bpf: add initial suite for selftestsDaniel Borkmann12-765/+1096
Add a start of a test suite for kernel selftests. This moves test_verifier and test_maps over to tools/testing/selftests/bpf/ along with various code improvements and also adds a script for invoking test_bpf module. The test suite can simply be run via selftest framework, f.e.: # cd tools/testing/selftests/bpf/ # make # make run_tests Both test_verifier and test_maps were kind of misplaced in samples/bpf/ directory and we were looking into adding them to selftests for a while now, so it can be picked up by kbuild bot et al and hopefully also get more exposure and thus new test case additions.

2016-10-18ethernet/intel: use core min/max MTU checkingJarod Wilson13-101/+62
e100: min_mtu 68, max_mtu 1500 - remove e100_change_mtu entirely, is identical to old eth_change_mtu, and no longer serves a purpose. No need to set min_mtu or max_mtu explicitly, as ether_setup() will already set them to 68 and 1500. e1000: min_mtu 46, max_mtu 16110 e1000e: min_mtu 68, max_mtu varies based on adapter fm10k: min_mtu 68, max_mtu 15342 - remove fm10k_change_mtu entirely, does nothing now i40e: min_mtu 68, max_mtu 9706 i40evf: min_mtu 68, max_mtu 9706 igb: min_mtu 68, max_mtu 9216 - There are two different "max" frame sizes claimed and both checked in the driver, the larger value wasn't relevant though, so I've set max_mtu to the smaller of the two values here to retain identical behavior. igbvf: min_mtu 68, max_mtu 9216 - Same issue as igb duplicated ixgb: min_mtu 68, max_mtu 16114 - Also remove pointless old == new check, as that's done in dev_set_mtu ixgbe: min_mtu 68, max_mtu 9710 ixgbevf: min_mtu 68, max_mtu dependent on hardware/firmware - Some hw can only handle up to max_mtu 1504 on a vf, others 9710 CC: netdev@vger.kernel.org CC: intel-wired-lan@lists.osuosl.org CC: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

tg3: min_mtu 60, max_mtu 9000/1500 bnxt: min_mtu 60, max_mtu 9000 bnx2x: min_mtu 46, max_mtu 9600 - Fix up ETH_OVREHEAD -> ETH_OVERHEAD while we're in here, remove duplicated defines from bnx2x_link.c. bnx2: min_mtu 46, max_mtu 9000 - Use more standard ETH_* defines while we're at it. bcm63xx_enet: min_mtu 46, max_mtu 2028 - compute_hw_mtu was made largely pointless, and thus merged back into bcm_enet_change_mtu. b44: min_mtu 60, max_mtu 1500 CC: netdev@vger.kernel.org CC: Michael Chan <michael.chan@broadcom.com> CC: Sony Chacko <sony.chacko@qlogic.com> CC: Ariel Elior <ariel.elior@qlogic.com> CC: Dept-HSGLinuxNICDev@qlogic.com CC: Siva Reddy Kallam <siva.kallam@broadcom.com> CC: Prashant Sreedharan <prashant@broadcom.com> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

atl2: min_mtu 40, max_mtu 1504 - Remove a few redundant defines that already have equivalents in if_ether.h. atl1: min_mtu 42, max_mtu 10218 atl1e: min_mtu 42, max_mtu 8170 atl1c: min_mtu 42, max_mtu 6122/1500 - GbE hardware gets a max_mtu of 6122, slower hardware gets 1500. alx: min_mtu 34, max_mtu 9256 - Not so sure that minimum MTU number is really what was intended, but that's what the math actually makes it out to be, due to max_frame manipulations and comparison in alx_change_mtu, rather than just comparing new_mtu. (I think 68 was the intended min_mtu value).

args.u.name_type is of type unsigned int and is always >= 0.
