2023-01-16r8169: reset bus if NIC isn't accessible after tx timeoutHeiner Kallweit
ASPM issues may result in the NIC not being accessible any longer. In this case disabling ASPM may not work. Therefore detect this case by checking whether register reads return ~0, and try to make the NIC accessible again by resetting the secondary bus. v2: - add exception handling for the case that pci_reset_bus() fails Suggested-by: Alexander Duyck <alexander.duyck@gmail.com> Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Alexander Duyck <alexanderduyck@fb.com> Signed-off-by: David S.

2023-01-16wifi: rtw89: fix assignation of TX BD RAM tableZong-Zhe Yang
TX BD's RAM table describes how HW allocates usable buffer section for each TX channel at fetch time. The total RAM size for TX BD is chip-dependent. For 8852BE, it has only half size (32) for TX channels of single band. Original table arrange total size (64) for dual band. It will overflow on 8852BE circuit and cause section conflicts between different TX channels. So, we do the changes below. * add another table for single band chip and export both kind of tables * point to the expected one in rtw89_pci_info by chip Signed-off-by: Zong-Zhe Yang <kevin_yang@realtek.com> Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230113090632.60957-4-pkshih@realtek.com

2023-01-16net: dsa: mv88e6xxx: Enable PTP receive for mv88e6390Kurt Kanzenbach
The switch receives management traffic such as STP and LLDP. However, PTP messages are not received, only transmitted. Ideally, the switch would trap all PTP messages to the management CPU. This particular switch has a PTP block which identifies PTP messages and traps them to a dedicated port. There is a register to program this destination. This is not used at the moment. Therefore, program it to the same port as the MGMT traffic is trapped to. This allows to receive PTP messages as soon as timestamping is enabled. In addition, the datasheet mentions that this register is not valid e.g., for 6190 variants. So, add a new PTP operation which is added for the 6390 and 6290 devices. Tested simply like this on Marvell 88E6390, revision 1: |/ # ptp4l -2 -i lan4 --tx_timestamp_timeout=40 -m |[...] |ptp4l[147.450]: master offset 56 s2 freq +1262 path delay 413 |ptp4l[148.450]: master offset 22 s2 freq +1244 path delay 434 |ptp4l[149.450]: master offset 5 s2 freq +1234 path delay 446 |ptp4l[150.451]: master offset 3 s2 freq +1233 path delay 451 |ptp4l[151.451]: master offset 1 s2 freq +1232 path delay 451 |ptp4l[152.451]: master offset -3 s2 freq +1229 path delay 451 |ptp4l[153.451]: master offset 9 s2 freq +1240 path delay 451 Link: https://lore.kernel.org/r/CAFSKS=PJBpvtRJxrR4sG1hyxpnUnQpiHg4SrUNzAhkWnyt9ivg@mail.gmail.com Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Tested-by: Vladimir Oltean <olteanv@gmail.com> Signed-off-by: David S.

2023-01-16net/sched: sch_taprio: fix possible use-after-freeEric Dumazet
syzbot reported a nasty crash [1] in net_tx_action() which made little sense until we got a repro. This repro installs a taprio qdisc, but providing an invalid TCA_RATE attribute. qdisc_create() has to destroy the just initialized taprio qdisc, and taprio_destroy() is called. However, the hrtimer used by taprio had already fired, therefore advance_sched() called __netif_schedule(). Then net_tx_action was trying to use a destroyed qdisc. We can not undo the __netif_schedule(), so we must wait until one cpu serviced the qdisc before we can proceed. Many thanks to Alexander Potapenko for his help.

Correct queue statistics reading. All queue statistics are stored as unsigned long values. The retrieval for ethtool fetches these values as u64. However, on some systems the size of the counters are 32 bit. That yields wrong queue statistic counters e.g., on arm32 systems such as the stm32mp157. Fix it by using the correct data type.

2023-01-16wifi: rndis_wlan: Prevent buffer overflow in rndis_query_oidSzymon Heidrich
Since resplen and respoffs are signed integers sufficiently large values of unsigned int len and offset members of RNDIS response will result in negative values of prior variables. This may be utilized to bypass implemented security checks to either extract memory contents by manipulating offset or overflow the data buffer via memcpy by manipulating both offset and len. Additionally assure that sum of resplen and respoffs does not overflow so buffer boundaries are kept.

2023-01-16Merge branch 'virtio-net-xdp-multi-buffer'David S. Miller
Heng Qi says: ==================== virtio-net: support multi buffer xdp Changes since PATCH v4: - Make netdev_warn() in [PATCH 2/10] independent from [PATCH 3/10]. Changes since PATCH v3: - Separate fix patch [2/10] for MTU calculation of single buffer xdp. Note that this patch needs to be backported to the stable branch. Changes since PATCH v2: - Even if single buffer xdp has a hole mechanism, there will be no problem (limiting mtu and turning off GUEST GSO), so there is no need to backport "[PATCH 1/9]"; - Modify calculation of MTU for single buffer xdp in virtnet_xdp_set(); - Make truesize in mergeable mode return to literal meaning; - Add some comments for legibility; Changes since RFC: - Using headroom instead of vi->xdp_enabled to avoid re-reading in add_recvbuf_mergeable(); - Disable GRO_HW and keep linearization for single buffer xdp; - Renamed to virtnet_build_xdp_buff_mrg(); - pr_debug() to netdev_dbg(); - Adjusted the order of the patch series. Currently, virtio net only supports xdp for single-buffer packets or linearized multi-buffer packets. This patchset supports xdp for multi-buffer packets, then larger MTU can be used if xdp sets the xdp.frags. This does not affect single buffer handling. In order to build multi-buffer xdp neatly, we integrated the code into virtnet_build_xdp_buff_mrg() for xdp. The first buffer is used for prepared xdp buff, and the rest of the buffers are added to its skb_shared_info structure. This structure can also be conveniently converted during XDP_PASS to get the corresponding skb. Since virtio net uses comp pages, and bpf_xdp_frags_increase_tail() is based on the assumption of the page pool, (rxq->frag_size - skb_frag_size(frag) - skb_frag_off(frag)) is negative in most cases. So we didn't set xdp_rxq->frag_size in virtnet_open() to disable the tail increase. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Build multi-buffer xdp using virtnet_build_xdp_buff_mrg(). For the prefilled buffer before xdp is set, we will probably use vq reset in the future. At the same time, virtio net currently uses comp pages, and bpf_xdp_frags_increase_tail() needs to calculate the tailroom of the last frag, which will involve the offset of the corresponding page and cause a negative value, so we disable tail increase by not setting xdp_rxq->frag_size.

2023-01-16virtio-net: build xdp_buff with multi buffersHeng Qi
Support xdp for multi buffer packets in mergeable mode. Putting the first buffer as the linear part for xdp_buff, and the rest of the buffers as non-linear fragments to struct skb_shared_info in the tailroom belonging to xdp_buff. Let 'truesize' return to its literal meaning, that is, when xdp is set, it includes the length of headroom and tailroom.

2023-01-16virtio-net: fix calculation of MTU for single-buffer xdpHeng Qi
When single-buffer xdp is loaded, the size of the buffer filled each time is 'sz = (PAGE_SIZE - headroom - tailroom)', which is the maximum packet length that the driver allows the device to pass in. Otherwise, the packet with a length greater than sz will come in, so num_buf will be greater than or equal to 2, and xdp_linearize_page() will be performed and the packet will be dropped because the total length is greater than PAGE_SIZE. So the maximum value of MTU for single-buffer xdp is 'max_sz = sz - ETH_HLEN'.

2023-01-16zonefs: Detect append writes at invalid locationsDamien Le Moal
Using REQ_OP_ZONE_APPEND operations for synchronous writes to sequential files succeeds regardless of the zone write pointer position, as long as the target zone is not full. This means that if an external (buggy) application writes to the zone of a sequential file underneath the file system, subsequent file write() operation will succeed but the file size will not be correct and the file will contain invalid data written by another application. Modify zonefs_file_dio_append() to check the written sector of an append write (returned in bio->bi_iter.bi_sector) and return -EIO if there is a mismatch with the file zone wp offset field. This change triggers a call to zonefs_io_error() and a zone check. Modify zonefs_io_error_cb() to not expose the unexpected data after the current inode size when the errors=remount-ro mode is used. Other error modes are correctly handled already.
