2023-11-06ice: Fix SRIOV LAG disable on non-compliant aggregateDave Ertman
If an attribute of an aggregate interface disqualifies it from supporting SRIOV, the driver will unwind the SRIOV support. Currently the driver is clearing the feature bit for all interfaces in the aggregate, but this is not allowing the other interfaces to unwind successfully on driver unload. Only clear the feature bit for the interface that is currently unwinding.

2023-11-02net: dsa: lan9303: consequently nested-lock physical MDIOAlexander Sverdlin
When LAN9303 is MDIO-connected two callchains exist into mdio->bus->write(): 1. switch ports 1&2 ("physical" PHYs): virtual (switch-internal) MDIO bus (lan9303_switch_ops->phy_{read|write})-> lan9303_mdio_phy_{read|write} -> mdiobus_{read|write}_nested 2. LAN9303 virtual PHY: virtual MDIO bus (lan9303_phy_{read|write}) -> lan9303_virt_phy_reg_{read|write} -> regmap -> lan9303_mdio_{read|write} If the latter functions just take mutex_lock(&sw_dev->device->bus->mdio_lock) it triggers a LOCKDEP false-positive splat. It's false-positive because the first mdio_lock in the second callchain above belongs to virtual MDIO bus, the second mdio_lock belongs to physical MDIO bus. Consequent annotation in lan9303_mdio_{read|write} as nested lock (similar to lan9303_mdio_phy_{read|write}, it's the same physical MDIO bus) prevents the following splat: WARNING: possible circular locking dependency detected 5.15.71 #1 Not tainted ------------------------------------------------------ kworker/u4:3/609 is trying to acquire lock: ffff000011531c68 (lan9303_mdio:131:(&lan9303_mdio_regmap_config)->lock){+.+.}-{3:3}, at: regmap_lock_mutex but task is already holding lock: ffff0000114c44d8 (&bus->mdio_lock){+.+.}-{3:3}, at: mdiobus_read which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&bus->mdio_lock){+.+.}-{3:3}: lock_acquire __mutex_lock mutex_lock_nested lan9303_mdio_read _regmap_read regmap_read lan9303_probe lan9303_mdio_probe mdio_probe really_probe __driver_probe_device driver_probe_device __device_attach_driver bus_for_each_drv __device_attach device_initial_probe bus_probe_device deferred_probe_work_func process_one_work worker_thread kthread ret_from_fork -> #0 (lan9303_mdio:131:(&lan9303_mdio_regmap_config)->lock){+.+.}-{3:3}: __lock_acquire lock_acquire.part.0 lock_acquire __mutex_lock mutex_lock_nested regmap_lock_mutex regmap_read lan9303_phy_read dsa_slave_phy_read __mdiobus_read mdiobus_read get_phy_device mdiobus_scan __mdiobus_register dsa_register_switch lan9303_probe lan9303_mdio_probe mdio_probe really_probe __driver_probe_device driver_probe_device __device_attach_driver bus_for_each_drv __device_attach device_initial_probe bus_probe_device deferred_probe_work_func process_one_work worker_thread kthread ret_from_fork other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&bus->mdio_lock); lock(lan9303_mdio:131:(&lan9303_mdio_regmap_config)->lock); lock(&bus->mdio_lock); lock(lan9303_mdio:131:(&lan9303_mdio_regmap_config)->lock); *** DEADLOCK *** 5 locks held by kworker/u4:3/609: #0: ffff000002842938 ((wq_completion)events_unbound){+.+.}-{0:0}, at: process_one_work #1: ffff80000bacbd60 (deferred_probe_work){+.+.}-{0:0}, at: process_one_work #2: ffff000007645178 (&dev->mutex){....}-{3:3}, at: __device_attach #3: ffff8000096e6e78 (dsa2_mutex){+.+.}-{3:3}, at: dsa_register_switch #4: ffff0000114c44d8 (&bus->mdio_lock){+.+.}-{3:3}, at: mdiobus_read stack backtrace: CPU: 1 PID: 609 Comm: kworker/u4:3 Not tainted 5.15.71 #1 Workqueue: events_unbound deferred_probe_work_func Call trace: dump_backtrace show_stack dump_stack_lvl dump_stack print_circular_bug check_noncircular __lock_acquire lock_acquire.part.0 lock_acquire __mutex_lock mutex_lock_nested regmap_lock_mutex regmap_read lan9303_phy_read dsa_slave_phy_read __mdiobus_read mdiobus_read get_phy_device mdiobus_scan __mdiobus_register dsa_register_switch lan9303_probe lan9303_mdio_probe ...

git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull sysctl updates from Luis Chamberlain: "To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array. Joel Granados has been doing all this work. On the v6.6 kernel we got the major infrastructure changes required to support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove the sentinel. Both arch and driver changes have been on linux-next for a bit less than a month. It is worth re-iterating the value: - this helps reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array - the extra 64-byte penalty is no longer inncurred now when we move sysctls out from kernel/sysctl.c to their own files For v6.8-rc1 expect removal of all the sentinels and also then the unneeded check for procname == NULL. The last two patches are fixes recently merged by Krister Johansen which allow us again to use softlockup_panic early on boot. This used to work but the alias work broke it. This is useful for folks who want to detect softlockups super early rather than wait and spend money on cloud solutions with nothing but an eventual hung kernel.

In this case, arvif->u.ap.ssid has its length maintained by arvif->u.ap.ssid_len which indicates it may not need to be NUL-terminated. Make this explicit with __nonstring and use a plain old memcpy. This is also consistent with future copies into arvif->u.ap.ssid: if (changed & BSS_CHANGED_SSID && vif->type == NL80211_IFTYPE_AP) { arvif->u.ap.ssid_len = vif->cfg.ssid_len; if (vif->cfg.ssid_len) memcpy(arvif->u.ap.ssid, vif->cfg.ssid, vif->cfg.ssid_len); arvif->u.ap.hidden_ssid = info->hidden_ssid; } Link: https://www.kernel.org/doc/html/latest/process/deprecated.html#strncpy-on-nul-terminated-strings [1] Link: https://github.com/KSPP/linux/issues/90 Cc: linux-hardening@vger.kernel.org Signed-off-by: Justin Stitt <justinstitt@google.com> Acked-by: Jeff Johnson <quic_jjohnson@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/20231024-strncpy-drivers-net-wireless-ath-ath10k-mac-c-v2-1-4c1f4cd4b4df@google.com

Wireless RNDIS USB is a new-style CFG80211 driver for 802.11b and 802.11g USB hardware from around 2004 to 2006. This makes it more modern than any of the others, but Kalle already classified it as "legacy" in commit 298e50ad8eb8f ("wifi: move raycs, wl3501 and rndis_wlan to legacy directory").

2023-10-30wifi: airo: replace deprecated strncpy with strscpy_padJustin Stitt
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. `extra` is clearly supposed to be NUL-terminated which is evident by the manual NUL-byte assignment as well as its immediate usage with strlen(). Moreover, let's NUL-pad since there is deliberate effort (48 instances) made elsewhere to zero-out buffers in these getters and setters: 6050 | memset(local->config.nodeName, 0, sizeof(local->config.nodeName)); 6130 | memset(local->config.rates, 0, 8); 6139 | memset(local->config.rates, 0, 8); 6414 | memset(key.key, 0, MAX_KEY_SIZE); 6497 | memset(extra, 0, 16); (to be clear, strncpy also NUL-padded -- we are matching that behavior) Considering the above, a suitable replacement is `strscpy_pad` due to the fact that it guarantees both NUL-termination and NUL-padding on the destination buffer. We can also replace the hard-coded size of "16" to IW_ESSID_MAX_SIZE because this function is a wext handler. In wext-core.c we have: static const struct iw_ioctl_description standard_ioctl[] = { ... [IW_IOCTL_IDX(SIOCGIWNICKN)] = { .header_type = IW_HEADER_TYPE_POINT, .token_size = 1, .max_tokens = IW_ESSID_MAX_SIZE, }, So the buffer size is (strangely) IW_ESSID_MAX_SIZE Link: https://www.kernel.org/doc/html/latest/process/deprecated.html#strncpy-on-nul-terminated-strings [1] Link: https://github.com/KSPP/linux/issues/90 Cc: linux-hardening@vger.kernel.org Signed-off-by: Justin Stitt <justinstitt@google.com> Reviewed-by: Jeff Johnson <quic_jjohnson@quicinc.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20231026-strncpy-drivers-net-wireless-cisco-airo-c-v2-1-413427249e47@google.com

To make hardware efficient to determine if RX ring is full, introduce new design that checks if reading and writing indices are equal. Comparing to old design, initial indices of both reading and writing indices are 0 that means empty, and hardware checks full by "writing index + 1 == reading index". The "+1" has extra cost for hardware, so new design is to avoid this. Take ring size is 256 as an example, the initial reading and writing indices are 255 and 0 respectively; the initial values mean empty. If two indices are the same, for example 5 and 5, it means ring is full. wp rp used_cnt state 255 0 0 initial (ring is empty) 255 1 1 receive 1st packet 255 2 2 receive 2nd packet 0 2 1 driver read 1st packet 1 2 0 driver read 2nd packet (ring is empty) : 5 5 255 ring is full Note: 'rp' is hardware writing index Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20231026120049.9187-4-pkshih@realtek.com
