Pull networking fixes from Jakub Kicinski: "We have a few fixes for long standing issues, in particular Eric's fix to not underestimate the skb sizes, and my fix for brokenness of register_netdevice() error path. They may uncover other bugs so we will keep an eye on them. Also included are Willem's fixes for kmap(_atomic). Looking at the "current release" fixes, it seems we are about one rc behind a normal cycle. We've previously seen an uptick of "people had run their test suites" / "humans actually tried to use new features" fixes between rc2 and rc3. Summary: Current release - regressions: - fix feature enforcement to allow NETIF_F_HW_TLS_TX if IP_CSUM && IPV6_CSUM - dcb: accept RTM_GETDCB messages carrying set-like DCB commands if user is admin for backward-compatibility - selftests/tls: fix selftests build after adding ChaCha20-Poly1305 Current release - always broken: - ppp: fix refcount underflow on channel unbridge - bnxt_en: clear DEFRAG flag in firmware message when retry flashing - smc: fix out of bound access in the new netlink interface Previous releases - regressions: - fix use-after-free with UDP GRO by frags - mptcp: better msk-level shutdown - rndis_host: set proper input size for OID_GEN_PHYSICAL_MEDIUM request - i40e: xsk: fix potential NULL pointer dereferencing Previous releases - always broken: - skb frag: kmap_atomic fixes - avoid 32 x truesize under-estimation for tiny skbs - fix issues around register_netdevice() failures - udp: prevent reuseport_select_sock from reading uninitialized socks - dsa: unbind all switches from tree when DSA master unbinds - dsa: clear devlink port type before unregistering slave netdevs - can: isotp: isotp_getname(): fix kernel information leak - mlxsw: core: Thermal control fixes - ipv6: validate GSO SKB against MTU before finish IPv6 processing - stmmac: use __napi_schedule() for PREEMPT_RT - net: mvpp2: remove Pause and Asym_Pause support Misc: - remove from MAINTAINERS folks who had been inactive for >5yrs" * tag 'net-5.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (58 commits) mptcp: fix locking in mptcp_disconnect() net: Allow NETIF_F_HW_TLS_TX if IP_CSUM && IPV6_CSUM MAINTAINERS: dccp: move Gerrit Renker to CREDITS MAINTAINERS: ipvs: move Wensong Zhang to CREDITS MAINTAINERS: tls: move Aviad to CREDITS MAINTAINERS: ena: remove Zorik Machulsky from reviewers MAINTAINERS: vrf: move Shrijeet to CREDITS MAINTAINERS: net: move Alexey Kuznetsov to CREDITS MAINTAINERS: altx: move Jay Cliburn to CREDITS net: avoid 32 x truesize under-estimation for tiny skbs nt: usb: USB_RTL8153_ECM should not default to y net: stmmac: fix taprio configuration when base_time is in the past net: stmmac: fix taprio schedule configuration net: tip: fix a couple kernel-doc markups net: sit: unregister_netdevice on newlink's error path net: stmmac: Fixed mtu channged by cache aligned cxgb4/chtls: Fix tid stuck due to wrong update of qid i40e: fix potential NULL pointer dereferencing net: stmmac: use __napi_schedule() for PREEMPT_RT can: mcp251xfd: mcp251xfd_handle_rxif_one(): fix wrong NULL pointer check ... -

Cited patch below blocked the TLS TX device offload unless HW_CSUM is set. This broke devices that use IP_CSUM && IP6_CSUM. Here we fix it. Note that the single HW_TLS_TX feature flag indicates support for both IPv4/6, hence it should still be disabled in case only one of (IP_CSUM | IPV6_CSUM) is set.

To make maintainers' lives easier we're trying to nudge people towards CCing all the relevant folks on patches, in an attempt to improve review rate. We have a check in patchwork which validates the CC list against get_maintainers.pl. It's a little awkward, however, to force people to CC maintainers who we haven't seen on the mailing list for years. This series removes from maintainers folks who didn't provide any tag (incl. authoring a patch) in the last 5 years. To ensure reasonable signal to noise ratio we only considered MAINTAINERS entries which had more than 100 patches fall under them in that time period. All this is purely a process-greasing exercise, I hope nobody sees this series as an affront. Most folks are moved to CREDITS, a couple entries are simply removed. The following inactive maintainers are kept, because they indicated the intention to come back in the near future: - Veaceslav Falico (bonding) - Christian Benvenuti (Cisco drivers) - Felix Fietkau (mtk-eth) - Mirko Linder (skge/sky2) Patches in this series contain report from a script which did the analysis. Big thanks to Jonathan Corbet for help and writing the script (although I feel like I used it differently than Jon may have intended ;)). The output format is thus: Subsystem $name Changes $reviewed / $total ($percent%) // how many changes to the subsystem had at least one ack/review Last activity: $date_of_most_recent_patch $maintainer/reviewer1: Author $last_commit_authored_by_the_person $how_many_in_5yrs Committer $last_committed $how_many Tags $last_tag_like_review_signoff_etc $how_many $maintainer/reviewer2: Author $last_commit_authored_by_the_person $how_many_in_5yrs Committer $last_committed $how_many Tags $last_tag_like_review_signoff_etc $how_many Top reviewers: // Top 3 reviewers (who are not listed in MAINTAINERS) [$count_of_reviews_and_acks]: $email INACTIVE MAINTAINER $name // maintainer / reviewer who has done nothing in last 5yrs v2: - keep Felix and Mirko Link: https://lore.kernel.org/r/20210114014912.2519931-1-kuba@kernel.orgSigned-off-by: -

Both virtio net and napi_get_frags() allocate skbs with a very small skb->head While using page fragments instead of a kmalloc backed skb->head might give a small performance improvement in some cases, there is a huge risk of under estimating memory usage. For both GOOD_COPY_LEN and GRO_MAX_HEAD, we can fit at least 32 allocations per page (order-3 page in x86), or even 64 on PowerPC We have been tracking OOM issues on GKE hosts hitting tcp_mem limits but consuming far more memory for TCP buffers than instructed in tcp_mem[2] Even if we force napi_alloc_skb() to only use order-0 pages, the issue would still be there on arches with PAGE_SIZE >= 32768 This patch makes sure that small skb head are kmalloc backed, so that other objects in the slab page can be reused instead of being held as long as skbs are sitting in socket queues. Note that we might in the future use the sk_buff napi cache, instead of going through a more expensive __alloc_skb() Another idea would be to use separate page sizes depending on the allocated length (to never have more than 4 frags per page) I would like to thank Greg Thelen for his precious help on this matter, analysing crash dumps is always a time consuming task.

The Synopsys TSN MAC supports Qbv base times in the past, but only up to a certain limit. As a result, a taprio qdisc configuration with a small base time (for example when treating the base time as a simple phase offset) is not applied by the hardware and silently ignored. This was observed on an NXP i.MX8MPlus device, but likely affects all TSN-variants of the MAC. Fix the issue by making sure the base time is in the future, pushing it by an integer amount of cycle times if needed. (a similar check is already done in several other taprio implementations, see for example drivers/net/ethernet/intel/igc/igc_tsn.c#L116 or drivers/net/dsa/sja1105/sja1105_ptp.h#L39).

When configuring a 802.1Qbv schedule through the tc taprio qdisc on an NXP i.MX8MPlus device, the effective cycle time differed from the requested one by N*96ns, with N number of entries in the Qbv Gate Control List. This is because the driver was adding a 96ns margin to each interval of the GCL, apparently to account for the IPG. The problem was observed on NXP i.MX8MPlus devices but likely affected all devices relying on the same configuration callback (dwmac 4.00, 4.10, 5.10 variants). Fix the issue by removing the margins, and simply setup the MAC with the provided cycle time value. This is the behavior expected by the user-space API, as altering the Qbv schedule timings would break standards conformance. This is also the behavior of several other Ethernet MAC implementations supporting taprio, including the dwxgmac variant of stmmac.

Currently, the function i40e_construct_skb_zc only frees the input xdp buffer when the output skb is successfully built. On error, the function i40e_clean_rx_irq_zc does not commit anything for the current packet descriptor and simply exits the packet descriptor processing loop, with the plan to restart the processing of this descriptor on the next invocation. Therefore, on error the ring next-to-clean pointer should not advance, the xdp i.e. *bi buffer should not be freed and the current buffer info should not be invalidated by setting *bi to NULL. Therefore, the *bi should only be set to NULL when the function i40e_construct_skb_zc is successful, otherwise a NULL *bi will be dereferenced when the work for the current descriptor is eventually restarted.

Use of __napi_schedule_irqoff() is not safe with PREEMPT_RT in which hard interrupts are not disabled while running the threaded interrupt. Using __napi_schedule() works for both PREEMPT_RT and mainline Linux, just at the cost of an additional check if interrupts are disabled for mainline (since they are already disabled).

Clang static analysis reports the following: net/rxrpc/key.c:657:11: warning: Assigned value is garbage or undefined toksize = toksizes[tok++]; ^ ~~~~~~~~~~~~~~~ rxrpc_read() contains two consecutive loops. The first loop calculates the token sizes and stores the results in toksizes[] and the second one uses the array. When there is an error in identifying the token in the first loop, the token is skipped, no change is made to the toksizes[] array. When the same error happens in the second loop, the token is not skipped. This will cause the toksizes[] array to be out of step and will overrun past the calculated sizes. Fix this by making both loops log a message and return an error in this case. This should only happen if a new token type is incompletely implemented, so it should normally be impossible to trigger this.

Karsten Graul says: ==================== net/smc: fix out of bound access in netlink interface Both patches fix possible out-of-bounds reads. The original code expected that snprintf() reads len-1 bytes from source and appends the terminating null, but actually snprintf() first copies len bytes and finally overwrites the last byte with a null. Fix this by using memcpy() and terminating the string afterwards. ==================== Link: https://lore.kernel.org/r/20210112162122.26832-1-kgraul@linux.ibm.comSigned-off-by:

Using snprintf() to convert not null-terminated strings to null terminated strings may cause out of bounds read in the source string. Therefore use memcpy() and terminate the target string with a null afterwards. Fixes: a3db10ef ("net/smc: Add support for obtaining SMCR device list") Signed-off-by:

Instead of re-implementing most of inet_shutdown, re-use such helper, and implement the MPTCP-specific bits at the 'proto' level. The msk-level disconnect() can now be invoked, lets provide a suitable implementation. As a side effect, this fixes bad state management for listener sockets. The latter could lead to division by 0 oops since commit ea4ca586 ("mptcp: refine MPTCP-level ack scheduling").

When the FW tells the driver to retry the INSTALL_UPDATE command after it has cleared the NVM area, the driver is not clearing the previously used ALLOWED_TO_DEFRAG flag. As a result the FW tries to defrag the NVM area a second time in a loop and can fail the request. Fixes: 1432c3f6 ("bnxt_en: Retry installing FW package under NO_SPACE error condition.")

The function bnxt_get_ulp_stat_ctxs() does not count the stats contexts used by the RDMA driver correctly when the RDMA driver is freeing the MSIX vectors. It assumes that if the RDMA driver is registered, the additional stats contexts will be needed. This is not true when the RDMA driver is about to unregister and frees the MSIX vectors. This slight error leads to over accouting of the stats contexts needed after the RDMA driver has unloaded. This will cause some firmware warning and error messages in dmesg during subsequent config. changes or ifdown/ifup. Fix it by properly accouting for extra stats contexts only if the RDMA driver is registered and MSIX vectors have been successfully requested.

This commit enables the use of the r8153_ecm driver, introduced with commit c1aedf01 ("net/usb/r8153_ecm: support ECM mode for RTL8153") for the Lenovo Powered USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip. This results in the following driver preference: - if r8152 is available, use the r8152 driver - if r8152 is not available, use the r8153_ecm driver This is done to prevent the NIC from constantly sending pause frames when the host system enters standby (fixed by using the r8152 driver in "r8152: Add Lenovo Powered USB-C Travel Hub"), while still allowing the device to work with the r8153_ecm driver as a fallback.
