The walk implementation of most qdisc class modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So we can reconstruct them. Signed-off-by:

Any change to the hardware timestamps configuration triggers nic restart, which breaks transmition and reception of network packets for a while. But there is no need to fully restart the device because while configuring hardware timestamps. The code for changing configuration runs after all of the initialisation, when the NIC is actually up and running. This patch changes the code that ioctl will only update configuration registers and will not trigger carrier status change, but in case of timestamps for all rx packetes it fallbacks to close()/open() sequnce because of synchronization issues in the hardware. Tested on BCM57504. Cc: Richard Cochran <richardcochran@gmail.com> Signed-off-by:

Pull networking fixes from Jakub Kicinski: "Including fixes from wifi, netfilter and can. A handful of awaited fixes here - revert of the FEC changes, bluetooth fix, fixes for iwlwifi spew. We added a warning in PHY/MDIO code which is triggering on a couple of platforms in a false-positive-ish way. If we can't iron that out over the week we'll drop it and re-add for 6.1. I've added a new "follow up fixes" section for fixes to fixes in 6.0-rcs but it may actually give the false impression that those are problematic or that more testing time would have caught them.

When reading the timestamp is required bnxt_tx_int() hands over the ownership of the completed skb to the PTP worker. The skb should not be used afterwards, as the worker may run before the rest of our code and free the skb, leading to a use-after-free. Since dev_kfree_skb_any() accepts NULL make the loss of ownership more obvious and set skb to NULL. Fixes: 83bb623c ("bnxt_en: Transmit and retrieve packet timestamps") Reviewed-by:

There is a separate receive path for small packets (under 256 bytes). Instead of allocating a new dma-capable skb to be used for the next packet, this path allocates a skb and copies the data into it (reusing the existing sbk for the next packet). There are two bytes of junk data at the beginning of every packet. I believe these are inserted in order to allow aligned DMA and IP headers. We skip over them using skb_reserve. Before copying over the data, we must use a barrier to ensure we see the whole packet. The current code only synchronizes len bytes, starting from the beginning of the packet, including the junk bytes. However, this leaves off the final two bytes in the packet. Synchronize the whole packet. To reproduce this problem, ping a HME with a payload size between 17 and 214 $ ping -s 17 <hme_address> which will complain rather loudly about the data mismatch. Small packets (below 60 bytes on the wire) do not have this issue. I suspect this is related to the padding added to increase the minimum packet size.

Fix a NULL dereference of the struct bonding.rr_tx_counter member because if a bond is initially created with an initial mode != zero (Round Robin) the memory required for the counter is never created and when the mode is changed there is never any attempt to verify the memory is allocated upon switching modes. This causes the following Oops on an aarch64 machine: [ 334.686773] Unable to handle kernel paging request at virtual address ffff2c91ac905000 [ 334.694703] Mem abort info: [ 334.697486] ESR = 0x0000000096000004 [ 334.701234] EC = 0x25: DABT (current EL), IL = 32 bits [ 334.706536] SET = 0, FnV = 0 [ 334.709579] EA = 0, S1PTW = 0 [ 334.712719] FSC = 0x04: level 0 translation fault [ 334.717586] Data abort info: [ 334.720454] ISV = 0, ISS = 0x00000004 [ 334.724288] CM = 0, WnR = 0 [ 334.727244] swapper pgtable: 4k pages, 48-bit VAs, pgdp=000008044d662000 [ 334.733944] [ffff2c91ac905000] pgd=0000000000000000, p4d=0000000000000000 [ 334.740734] Internal error: Oops: 96000004 [#1] SMP [ 334.745602] Modules linked in: bonding tls veth rfkill sunrpc arm_spe_pmu vfat fat acpi_ipmi ipmi_ssif ixgbe igb i40e mdio ipmi_devintf ipmi_msghandler arm_cmn arm_dsu_pmu cppc_cpufreq acpi_tad fuse zram crct10dif_ce ast ghash_ce sbsa_gwdt nvme drm_vram_helper drm_ttm_helper nvme_core ttm xgene_hwmon [ 334.772217] CPU: 7 PID: 2214 Comm: ping Not tainted 6.0.0-rc4-00133-g64ae13ed #4 [ 334.779950] Hardware name: GIGABYTE R272-P31-00/MP32-AR1-00, BIOS F18v (SCP: 1.08.20211002) 12/01/2021 [ 334.789244] pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 334.796196] pc : bond_rr_gen_slave_id+0x40/0x124 [bonding] [ 334.801691] lr : bond_xmit_roundrobin_slave_get+0x38/0xdc [bonding] [ 334.807962] sp : ffff8000221733e0 [ 334.811265] x29: ffff8000221733e0 x28: ffffdbac8572d198 x27: ffff80002217357c [ 334.818392] x26: 000000000000002a x25: ffffdbacb33ee000 x24: ffff07ff980fa000 [ 334.825519] x23: ffffdbacb2e398ba x22: ffff07ff98102000 x21: ffff07ff981029c0 [ 334.832646] x20: 0000000000000001 x19: ffff07ff981029c0 x18: 0000000000000014 [ 334.839773] x17: 0000000000000000 x16: ffffdbacb1004364 x15: 0000aaaabe2f5a62 [ 334.846899] x14: ffff07ff8e55d968 x13: ffff07ff8e55db30 x12: 0000000000000000 [ 334.854026] x11: ffffdbacb21532e8 x10: 0000000000000001 x9 : ffffdbac857178ec [ 334.861153] x8 : ffff07ff9f6e5a28 x7 : 0000000000000000 x6 : 000000007c2b3742 [ 334.868279] x5 : ffff2c91ac905000 x4 : ffff2c91ac905000 x3 : ffff07ff9f554400 [ 334.875406] x2 : ffff2c91ac905000 x1 : 0000000000000001 x0 : ffff07ff981029c0 [ 334.882532] Call trace: [ 334.884967] bond_rr_gen_slave_id+0x40/0x124 [bonding] [ 334.890109] bond_xmit_roundrobin_slave_get+0x38/0xdc [bonding] [ 334.896033] __bond_start_xmit+0x128/0x3a0 [bonding] [ 334.901001] bond_start_xmit+0x54/0xb0 [bonding] [ 334.905622] dev_hard_start_xmit+0xb4/0x220 [ 334.909798] __dev_queue_xmit+0x1a0/0x720 [ 334.913799] arp_xmit+0x3c/0xbc [ 334.916932] arp_send_dst+0x98/0xd0 [ 334.920410] arp_solicit+0xe8/0x230 [ 334.923888] neigh_probe+0x60/0xb0 [ 334.927279] __neigh_event_send+0x3b0/0x470 [ 334.931453] neigh_resolve_output+0x70/0x90 [ 334.935626] ip_finish_output2+0x158/0x514 [ 334.939714] __ip_finish_output+0xac/0x1a4 [ 334.943800] ip_finish_output+0x40/0xfc [ 334.947626] ip_output+0xf8/0x1a4 [ 334.950931] ip_send_skb+0x5c/0x100 [ 334.954410] ip_push_pending_frames+0x3c/0x60 [ 334.958758] raw_sendmsg+0x458/0x6d0 [ 334.962325] inet_sendmsg+0x50/0x80 [ 334.965805] sock_sendmsg+0x60/0x6c [ 334.969286] __sys_sendto+0xc8/0x134 [ 334.972853] __arm64_sys_sendto+0x34/0x4c [ 334.976854] invoke_syscall+0x78/0x100 [ 334.980594] el0_svc_common.constprop.0+0x4c/0xf4 [ 334.985287] do_el0_svc+0x38/0x4c [ 334.988591] el0_svc+0x34/0x10c [ 334.991724] el0t_64_sync_handler+0x11c/0x150 [ 334.996072] el0t_64_sync+0x190/0x194 [ 334.999726] Code: b9001062 f9403c02 d53cd044 8b040042 (b8210040) [ 335.005810] ---[ end trace 0000000000000000 ]--- [ 335.010416] Kernel panic - not syncing: Oops: Fatal exception in interrupt [ 335.017279] SMP: stopping secondary CPUs [ 335.021374] Kernel Offset: 0x5baca8eb0000 from 0xffff800008000000 [ 335.027456] PHYS_OFFSET: 0x80000000 [ 335.030932] CPU features: 0x0000,0085c029,19805c82 [ 335.035713] Memory Limit: none [ 335.038756] Rebooting in 180 seconds..
