Somehow, I missed a healthy number of ethernet drivers in the last pass. Most of these drivers either were in need of an updated max_mtu to make jumbo frames possible to enable again. In a few cases, also setting a different min_mtu to match previous lower bounds. There are also a few drivers that had no upper bounds checking, so they're getting a brand new ETH_MAX_MTU that is identical to IP_MAX_MTU, but accessible by includes all ethernet and ethernet-like drivers all have already. acenic: - min_mtu = 0, max_mtu = 9000 amazon/ena: - min_mtu = 128, max_mtu = adapter->max_mtu amd/xgbe: - min_mtu = 0, max_mtu = 9000 sb1250: - min_mtu = 0, max_mtu = 1518 cxgb3: - min_mtu = 81, max_mtu = 65535 cxgb4: - min_mtu = 81, max_mtu = 9600 cxgb4vf: - min_mtu = 81, max_mtu = 65535 benet: - min_mtu = 256, max_mtu = 9000 ibmveth: - min_mtu = 68, max_mtu = 65535 ibmvnic: - min_mtu = adapter->min_mtu, max_mtu = adapter->max_mtu - remove now redundant ibmvnic_change_mtu jme: - min_mtu = 1280, max_mtu = 9202 mv643xx_eth: - min_mtu = 64, max_mtu = 9500 mlxsw: - min_mtu = 0, max_mtu = 65535 - Basically bypassing the core checks, and instead relying on dynamic checks in the respective switch drivers' ndo_change_mtu functions ns83820: - min_mtu = 0 - remove redundant ns83820_change_mtu, only checked for mtu > 1500 netxen: - min_mtu = 0, max_mtu = 8000 (P2), max_mtu = 9600 (P3) qlge: - min_mtu = 1500, max_mtu = 9000 - driver only supports setting mtu to 1500 or 9000, so the core check only rules out < 1500 and > 9000, qlge_change_mtu still needs to check that the value is 1500 or 9000 qualcomm/emac: - min_mtu = 46, max_mtu = 9194 xilinx_axienet: - min_mtu = 64, max_mtu = 9000 Fixes: 61e84623 ("net: centralize net_device min/max MTU checking") CC: netdev@vger.kernel.org CC: Jes Sorensen <jes@trained-monkey.org> CC: Netanel Belgazal <netanel@annapurnalabs.com> CC: Tom Lendacky <thomas.lendacky@amd.com> CC: Santosh Raspatur <santosh@chelsio.com> CC: Hariprasad S <hariprasad@chelsio.com> CC: Sathya Perla <sathya.perla@broadcom.com> CC: Ajit Khaparde <ajit.khaparde@broadcom.com> CC: Sriharsha Basavapatna <sriharsha.basavapatna@broadcom.com> CC: Somnath Kotur <somnath.kotur@broadcom.com> CC: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> CC: John Allen <jallen@linux.vnet.ibm.com> CC: Guo-Fu Tseng <cooldavid@cooldavid.org> CC: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> CC: Jiri Pirko <jiri@mellanox.com> CC: Ido Schimmel <idosch@mellanox.com> CC: Manish Chopra <manish.chopra@qlogic.com> CC: Sony Chacko <sony.chacko@qlogic.com> CC: Rajesh Borundia <rajesh.borundia@qlogic.com> CC: Timur Tabi <timur@codeaurora.org> CC: Anirudha Sarangi <anirudh@xilinx.com> CC: John Linn <John.Linn@xilinx.com> Signed-off-by:

Also SYN_RECV since request sockets are stored in the ehash table : 1) inet_diag_dump_icsk() no longer need to clear cb->args[3] and cb->args[4] that were used as cursors while iterating the old per listener hash table. 2) Also factorize a test : No need to scan listening_hash[] if r->id.idiag_dport is not zero.

The patch isolating the u16 writes for pxa assumed all machine_is_*() calls were removed, and therefore removed the mach-types.h include which provided them. Unfortunately 2 machine_is_*() remained in smc91x.c file including smc91x.h from which the include was removed, triggering the error: drivers/net/ethernet/smsc/smc91x.c: In function ‘smc_drv_probe’: drivers/net/ethernet/smsc/smc91x.c:2380:2: error: implicit declaration of function ‘machine_is_assabet’ [-Werror=implicit-function-declaration] if (machine_is_assabet() && machine_has_neponset()) This adds back the wrongly removed include.

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.

Robert Jarzmik says: ==================== support smc91x on mainstone and devicetree This series aims at bringing support to mainstone board on a device-tree based build, as what is already in place for legacy mainstone. The bulk of the mainstone "specific" behavior is that a u16 write doesn't work on a address of the form 4*n + 2, while it works on 4*n. The legacy workaround was in SMC_outw(), with calls to machine_is_mainstone(). These calls don't work with a pxa27x-dt machine type, which is used when a generic device-tree pxa27x machine is used to boot the mainstone board. Therefore, this series enables the smc91c111 adapter of the mainstone board to work on a device-tree build, exaclty as it's been working for years with the legacy arch/arm/mach-pxa/mainstone.c definition. As a sum up, this extends an existing mechanism to device-tree based pxa platforms. ==================== Signed-off-by:

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. This patch was tested on 2 PXA platforms : mainstone, which relies on the workaround, and lubbock, which doesn't. Signed-off-by:

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.

The second case just flips the ordering of the enslavements: ip link set bond1 master bridge ip link set macvlan master myvrf Then run: ip link delete bond1 ip link delete myvrf The vrf delete command hangs because myvrf has a reference that has not been released. In this case the removal code does not account for 2 paths between eth3 and myvrf - one from bridge to vrf and the other through the macvlan. Rather than try to maintain a linked list of all upper and lower devices per netdevice, only track the direct neighbors. The remaining stack can be determined by recursively walking the neighbors. The existing netdev_for_each_all_upper_dev_rcu, netdev_for_each_all_lower_dev and netdev_for_each_all_lower_dev_rcu macros are replaced with APIs that walk the upper and lower device lists. The new APIs take a callback function and a data arg that is passed to the callback for each device in the list. Drivers using the old macros are converted in separate patches to make it easier on reviewers. It is an API conversion only; no functional change is intended. v3 - address Stephen's comment to simplify logic and remove typecasts v2 - fixed bond0 references in cover-letter - fixed definition of netdev_next_lower_dev_rcu to mirror the upper_dev version. ==================== Signed-off-by:
