In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Add flexible array to represent start of buf_info, improving readability and avoid future warning where memcpy() thinks it is writing past the end of the structure. Signed-off-by:

In case CONFIG_VLAN_8021Q is not set, there will be no call down to the b53 driver to ensure that the default PVID VLAN entry will be configured with the appropriate untagged attribute towards the CPU port. We were implicitly relying on dsa_slave_vlan_rx_add_vid() to do that for us, instead make it explicit. Reported-by:

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. To avoid having memcpy() think a u64 "prof" is being written beyond, adjust the prof member type by adding struct nix_bandprof_s to the union to match the other structs. This silences the following future warning: In file included from ./include/linux/string.h:253, from ./include/linux/bitmap.h:10, from ./include/linux/cpumask.h:12, from ./arch/x86/include/asm/cpumask.h:5, from ./arch/x86/include/asm/msr.h:11, from ./arch/x86/include/asm/processor.h:22, from ./arch/x86/include/asm/timex.h:5, from ./include/linux/timex.h:65, from ./include/linux/time32.h:13, from ./include/linux/time.h:60, from ./include/linux/stat.h:19, from ./include/linux/module.h:13, from drivers/net/ethernet/marvell/octeontx2/af/rvu_nix.c:11: In function '__fortify_memcpy_chk', inlined from '__fortify_memcpy' at ./include/linux/fortify-string.h:310:2, inlined from 'rvu_nix_blk_aq_enq_inst' at drivers/net/ethernet/marvell/octeontx2/af/rvu_nix.c:910:5: ./include/linux/fortify-string.h:268:4: warning: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); please use struct_group() [-Wattribute-warning] 268 | __write_overflow_field(); | ^~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/marvell/octeontx2/af/rvu_nix.c: ... else if (req->ctype == NIX_AQ_CTYPE_BANDPROF) memcpy(&rsp->prof, ctx, sizeof(struct nix_bandprof_s)); ...

Sergey Ryazanov says: ==================== net: WWAN link creation improvements This series is intended to make the WWAN network links management easier for WWAN device drivers. The series begins with adding support for network links creation to the WWAN HW simulator to facilitate code testing. Then there are a couple of changes that prepe the WWAN core code for further modifications. The following patches (4-6) simplify driver unregistering procedures by performing the created links cleanup in the WWAN core. 7th patch is to avoid the odd hold of a driver module. Next patches (8th and 9th) make it easier for drivers to create a network interface for a default data channel. Finally, 10th patch adds support for reporting of data link (aka channel aka context) id to make user aware which network interface is bound to which WWAN device data channel. All core changes have been tested with the HW simulator. The MHI and IOSM drivers were only compile tested as I have no access to this hardware. So the coresponding patches require ACK from the driver authors. Changelog: v1 -> v2: * rebased on top of latest net-next * patch that reworks the creation of mhi_net default netdev was dropped; as Loic explained, this network device has different purpose depending on a driver mode; Loic has a plan to rework the mhi_net driver, so we will defer the default netdev creation reworkings * add a new patch that creates a default network interface for IOSM modems * 7th, 8th, 10th patches have a minor updates (see the patches for details) ==================== Signed-off-by: -

The WWAN core not only multiplex the netdev configuration data, but process it too, and needs some space to store its private data associated with the netdev. Add a structure to keep common WWAN core data. The structure will be stored inside the netdev private data before WWAN driver private data and have a field to make it easier to access the driver data. Also add a helper function that simplifies drivers access to their data. At the moment we use the common WWAN private data to store the WWAN data link (channel) id at the time the link is created, and report it back to user using the .fill_info() RTNL callback. This should help the user to be aware which network interface is bound to which WWAN device data channel. Signed-off-by:

Sergey Ryazanov authored
Most, if not each WWAN device driver will create a netdev for the default data channel. Therefore, add an option for the WWAN netdev ops registration function to create a default netdev for the WWAN device. A WWAN device driver should pass a default data channel link id to the ops registering function to request the creation of a default netdev, or a special value WWAN_NO_DEFAULT_LINK to inform the WWAN core that the default netdev should not be created. For now, only wwan_hwsim utilize the default link creation option. Other drivers will be reworked next. Signed-off-by:

The WWAN netdev ops owner holding was used to protect from the unexpected memory disappear. This approach causes a dependency cycle (driver -> core -> driver) and effectively prevents a WWAN driver unloading. E.g. WWAN hwsim could not be unloaded until all simulated devices are removed: ~# modprobe wwan_hwsim devices=2 ~# lsmod | grep wwan wwan_hwsim 16384 2 wwan 20480 1 wwan_hwsim ~# rmmod wwan_hwsim rmmod: ERROR: Module wwan_hwsim is in use ~# echo > /sys/kernel/debug/wwan_hwsim/hwsim0/destroy ~# echo > /sys/kernel/debug/wwan_hwsim/hwsim1/destroy ~# lsmod | grep wwan wwan_hwsim 16384 0 wwan 20480 1 wwan_hwsim ~# rmmod wwan_hwsim For a real device driver this will cause an inability to unload module until a served device is physically detached. Since the last commit we are removing all child netdev(s) when a driver unregister the netdev ops. This allows us to permit the driver unloading, since any sane driver will call ops unregistering on a device deinitialization. So, remove the holding of an ops owner to make it easier to unload a driver module. The owner field has also beed removed from the ops structure as there are no more users of this field.

Since the last commit, the WWAN core will remove all our network interfaces for us at the time of the WWAN netdev ops unregistering. Therefore, we can safely drop the custom code that cleans the list of created netdevs. Anyway it no longer removes any netdev, since all netdevs were removed earlier in the wwan_unregister_ops() call.

We use the ops owner module hold to protect against ops memory disappearing. But this approach does not protect us from a driver that unregisters ops but forgets to remove netdev(s) that were created using this ops. In such case, we are left with netdev(s), which can not be removed since ops is gone. Moreover, batch netdevs removing on deinitialization is a desireable option for WWAN drivers as it is a quite common task. Implement deletion of all created links on WWAN netdev ops unregistering in the same way that RTNL removes all links on RTNL ops unregistering. Simply remove all child netdevs of a device whose WWAN netdev ops is unregistering. This way we protecting the kernel from buggy drivers and make it easier to write a driver deinitialization code.

Use unregister_netdevice_queue() instead of simple unregister_netdevice() if the WWAN netdev ops does not provide a dellink callback. This will help to accelerate deletion of multiple netdevs. Signed-off-by:

The setup callback will be unconditionally passed to the alloc_netdev_mqs(), where the NULL pointer dereference will cause the kernel panic. So refuse to register WWAN netdev ops with warning generation if the setup callback is not provided. Signed-off-by:

Sergey Ryazanov authored
It is unlikely that RTNL callbacks will call WWAN ops (un-)register functions, but it is highly likely that the ops (un-)register functions will use RTNL link create/destroy handlers. So move the WWAN network interface ops (un-)register functions below the RTNL callbacks to be able to call them without forward declarations. No functional changes, just code relocation.

Mat Martineau says: ==================== mptcp: A few optimizations Here is a set of patches that we've accumulated and tested in the MPTCP tree. Patch 1 removes the MPTCP-level tx skb cache that added complexity but did not provide a meaningful benefit. Patch 2 uses the fast socket lock in more places. Patch 3 improves handling of a data-ready flag. Patch 4 deletes an unnecessary and racy connection state check. Patch 5 adds a MIB counter for one type of invalid MPTCP header. Patch 6 improves self test failure output. ==================== Signed-off-by: -

Currently we check the msk state to avoid enqueuing new skbs at msk shutdown time. Such test is racy - as we can't acquire the msk socket lock - and useless, as the caller already checked the subflow field 'disposable', covering the same scenario in a race free manner - read and updated under the ssk socket lock.

As we know that AVB is enabled by default, and the ENET IP design is queue 0 for best effort, queue 1&2 for AVB Class A&B. Bandwidth of each queue 1&2 set in driver is 50%, TX bandwidth fluctuated when selecting tx queues randomly with FEC_QUIRK_HAS_AVB quirk available. This patch adds ndo_select_queue callback to select queues for transmitting to fix this issue. It will always return queue 0 if this is not a vlan packet, and return queue 1 or 2 based on priority of vlan packet. You may complain that in fact we only use single queue for trasmitting if we are not targeted to VLAN. Yes, but seems we have no choice, since AVB is enabled when the driver probed, we can't switch this feature dynamicly. After compare multiple queues to single queue, TX throughput almost no improvement. One way we can implemet is to configure the driver to multiple queues with Round-robin scheme by default. Then add ndo_setup_tc callback to enable/disable AVB feature for users. Unfortunately, ENET AVB IP seems not follow the standard 802.1Qav spec. We only can program DMAnCFG[IDLE_SLOPE] field to calculate bandwidth fraction. And idle slope is restricted to certain valus (a total of 19). It's far away from CBS QDisc implemented in Linux TC framework. If you strongly suggest to do this, I think we only can support limited numbers of bandwidth and reject others, but it's really urgly and wried. With this patch, VLAN tagged packets route to queue 0/1/2 based on vlan priority; VLAN untagged packets route to queue 0. Tested-by:
