2022-02-18net: mvpp2: always set port pcs opsJeremy Linton
Booting a MACCHIATObin with 5.17, the system OOPs with a null pointer deref when the network is started. This is caused by the pcs->ops structure being null in mcpp2_acpi_start() when it tries to call pcs_config(). Hoisting the code which sets pcs_gmac.ops and pcs_xlg.ops, assuring they are always set, fixes the problem. The OOPs looks like: [ 18.687760] Unable to handle kernel access to user memory outside uaccess routines at virtual address 0000000000000010 [ 18.698561] Mem abort info: [ 18.698564] ESR = 0x96000004 [ 18.698567] EC = 0x25: DABT (current EL), IL = 32 bits [ 18.709821] SET = 0, FnV = 0 [ 18.714292] EA = 0, S1PTW = 0 [ 18.718833] FSC = 0x04: level 0 translation fault [ 18.725126] Data abort info: [ 18.729408] ISV = 0, ISS = 0x00000004 [ 18.734655] CM = 0, WnR = 0 [ 18.738933] user pgtable: 4k pages, 48-bit VAs, pgdp=0000000111bbf000 [ 18.745409] [0000000000000010] pgd=0000000000000000, p4d=0000000000000000 [ 18.752235] Internal error: Oops: 96000004 [#1] SMP [ 18.757134] Modules linked in: rfkill ip_set nf_tables nfnetlink qrtr sunrpc vfat fat omap_rng fuse zram xfs crct10dif_ce mvpp2 ghash_ce sbsa_gwdt phylink xhci_plat_hcd ahci_plam [ 18.773481] CPU: 0 PID: 681 Comm: NetworkManager Not tainted 5.17.0-0.rc3.89.fc36.aarch64 #1 [ 18.781954] Hardware name: Marvell Armada 7k/8k Family Board /Armada 7k/8k Family Board , BIOS EDK II Jun 4 2019 [ 18.795222] pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 18.802213] pc : mvpp2_start_dev+0x2b0/0x300 [mvpp2] [ 18.807208] lr : mvpp2_start_dev+0x298/0x300 [mvpp2] [ 18.812197] sp : ffff80000b4732c0 [ 18.815522] x29: ffff80000b4732c0 x28: 0000000000000000 x27: ffffccab38ae57f8 [ 18.822689] x26: ffff6eeb03065a10 x25: ffff80000b473a30 x24: ffff80000b4735b8 [ 18.829855] x23: 0000000000000000 x22: 00000000000001e0 x21: ffff6eeb07b6ab68 [ 18.837021] x20: ffff6eeb07b6ab30 x19: ffff6eeb07b6a9c0 x18: 0000000000000014 [ 18.844187] x17: 00000000f6232bfe x16: ffffccab899b1dc0 x15: 000000006a30f9fa [ 18.851353] x14: 000000003b77bd50 x13: 000006dc896f0e8e x12: 001bbbfccfd0d3a2 [ 18.858519] x11: 0000000000001528 x10: 0000000000001548 x9 : ffffccab38ad0fb0 [ 18.865685] x8 : ffff80000b473330 x7 : 0000000000000000 x6 : 0000000000000000 [ 18.872851] x5 : 0000000000000000 x4 : 0000000000000000 x3 : ffff80000b4732f8 [ 18.880017] x2 : 000000000000001a x1 : 0000000000000002 x0 : ffff6eeb07b6ab68 [ 18.887183] Call trace: [ 18.889637] mvpp2_start_dev+0x2b0/0x300 [mvpp2] [ 18.894279] mvpp2_open+0x134/0x2b4 [mvpp2] [ 18.898483] __dev_open+0x128/0x1e4 [ 18.901988] __dev_change_flags+0x17c/0x1d0 [ 18.906187] dev_change_flags+0x30/0x70 [ 18.910038] do_setlink+0x278/0xa7c [ 18.913540] __rtnl_newlink+0x44c/0x7d0 [ 18.917391] rtnl_newlink+0x5c/0x8c [ 18.920892] rtnetlink_rcv_msg+0x254/0x314 [ 18.925006] netlink_rcv_skb+0x48/0x10c [ 18.928858] rtnetlink_rcv+0x24/0x30 [ 18.932449] netlink_unicast+0x290/0x2f4 [ 18.936386] netlink_sendmsg+0x1d0/0x41c [ 18.940323] sock_sendmsg+0x60/0x70 [ 18.943825] ____sys_sendmsg+0x248/0x260 [ 18.947762] ___sys_sendmsg+0x74/0xa0 [ 18.951438] __sys_sendmsg+0x64/0xcc [ 18.955027] __arm64_sys_sendmsg+0x30/0x40 [ 18.959140] invoke_syscall+0x50/0x120 [ 18.962906] el0_svc_common.constprop.0+0x4c/0xf4 [ 18.967629] do_el0_svc+0x30/0x9c [ 18.970958] el0_svc+0x28/0xb0 [ 18.974025] el0t_64_sync_handler+0x10c/0x140 [ 18.978400] el0t_64_sync+0x1a4/0x1a8 [ 18.982078] Code: 52800004 b9416262 aa1503e0 52800041 (f94008a5) [ 18.988196] ---[ end trace 0000000000000000 ]--- Fixes: cff056322372 ("net: mvpp2: use .mac_select_pcs() interface") Suggested-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: Jeremy Linton <jeremy.linton@arm.com> Reviewed-by: Marcin Wojtas <mw@semihalf.com> Link: https://lore.kernel.org/r/20220214231852.3331430-1-jeremy.linton@arm.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-02-18ice: fix concurrent reset and removal of VFsJacob Keller
Commit c503e63200c6 ("ice: Stop processing VF messages during teardown") introduced a driver state flag, ICE_VF_DEINIT_IN_PROGRESS, which is intended to prevent some issues with concurrently handling messages from VFs while tearing down the VFs. This change was motivated by crashes caused while tearing down and bringing up VFs in rapid succession. It turns out that the fix actually introduces issues with the VF driver caused because the PF no longer responds to any messages sent by the VF during its .remove routine. This results in the VF potentially removing its DMA memory before the PF has shut down the device queues. Additionally, the fix doesn't actually resolve concurrency issues within the ice driver. It is possible for a VF to initiate a reset just prior to the ice driver removing VFs. This can result in the remove task concurrently operating while the VF is being reset. This results in similar memory corruption and panics purportedly fixed by that commit. Fix this concurrency at its root by protecting both the reset and removal flows using the existing VF cfg_lock. This ensures that we cannot remove the VF while any outstanding critical tasks such as a virtchnl message or a reset are occurring. This locking change also fixes the root cause originally fixed by commit c503e63200c6 ("ice: Stop processing VF messages during teardown"), so we can simply revert it. Note that I kept these two changes together because simply reverting the original commit alone would leave the driver vulnerable to worse race conditions.

2022-02-18ice: Match on all profiles in slow-pathWojciech Drewek
In switchdev mode, slow-path rules need to match all protocols, in order to correctly redirect unfiltered or missed packets to the uplink. To set this up for the virtual function to uplink flow, the rule that redirects packets to the control VSI must have the tunnel type set to ICE_SW_TUN_AND_NON_TUN. As a result of that new tunnel type being set, ice_get_compat_fv_bitmap will select ICE_PROF_ALL. At that point all profiles would be selected for this rule, resulting in the desired behavior. Without this change slow-path would not work with tunnel protocols.

2022-02-18drivers: hamradio: 6pack: fix UAF bug caused by mod_timer()Duoming Zhou
When a 6pack device is detaching, the sixpack_close() will act to cleanup necessary resources. Although del_timer_sync() in sixpack_close() won't return if there is an active timer, one could use mod_timer() in sp_xmit_on_air() to wake up timer again by calling userspace syscall such as ax25_sendmsg(), ax25_connect() and ax25_ioctl(). This unexpected waked handler, sp_xmit_on_air(), realizes nothing about the undergoing cleanup and may still call pty_write() to use driver layer resources that have already been released. One of the possible race conditions is shown below: (USE) | (FREE) ax25_sendmsg() | ax25_queue_xmit() | ... | sp_xmit() | sp_encaps() | sixpack_close() sp_xmit_on_air() | del_timer_sync(&sp->tx_t) mod_timer(&sp->tx_t,...) | ... | unregister_netdev() | ... (wait a while) | tty_release() | tty_release_struct() | release_tty() sp_xmit_on_air() | tty_kref_put(tty_struct) //FREE pty_write(tty_struct) //USE | ... The corresponding fail log is shown below: =============================================================== BUG: KASAN: use-after-free in __run_timers.part.0+0x170/0x470 Write of size 8 at addr ffff88800a652ab8 by task swapper/2/0 ...

This patch reorders the del_timer_sync() after the unregister_netdev() to avoid UAF bugs. Because the unregister_netdev() is well synchronized, it flushs out any pending queues, waits the refcount of net_device decreases to zero and removes net_device from kernel. There is not any running routines after executing unregister_netdev(). Therefore, we could not arouse timer from userspace again.

2022-02-18iwlwifi: support new queue allocation commandJohannes Berg
Newer firmware versions will support a new queue allocation command, in order to deal with MLD where multiple stations are used for a single queue. Add support for the new command. This requires some refactoring of the queue allocation API, which now gets - the station mask instead of the station ID - the flags without the "enable" flag, since that's no longer used in the new API Additionally, this new API now requires that we remove queues before removing a station, the firmware will no longer do that internally. Also add support for that.

A scan during active P2P GO operation, i.e., data traffic with clients, can impact the throughput and latency of such traffic. Thus, when scan is requested while there is an active P2P GO and low latency is asserted: - Ask the FW scan logic to respect the P2P GO activity during the scheduling of the scan operation to minimize the impact on the throughput and latency. - Force scan to perform EBS before starting the scan to reduce the number of scanned channels.
