2023-10-19net: ethernet: ti: Fix mixed module-builtin objectMD Danish Anwar
With CONFIG_TI_K3_AM65_CPSW_NUSS=y and CONFIG_TI_ICSSG_PRUETH=m, k3-cppi-desc-pool.o is linked to a module and also to vmlinux even though the expected CFLAGS are different between builtins and modules. The build system is complaining about the following: k3-cppi-desc-pool.o is added to multiple modules: icssg-prueth ti-am65-cpsw-nuss Introduce the new module, k3-cppi-desc-pool, to provide the common functions to ti-am65-cpsw-nuss and icssg-prueth.

2023-10-19perf: Disallow mis-matched inherited group readsPeter Zijlstra
Because group consistency is non-atomic between parent (filedesc) and children (inherited) events, it is possible for PERF_FORMAT_GROUP read() to try and sum non-matching counter groups -- with non-sensical results. Add group_generation to distinguish the case where a parent group removes and adds an event and thus has the same number, but a different configuration of events as inherited groups. This became a problem when commit fa8c269353d5 ("perf/core: Invert perf_read_group() loops") flipped the order of child_list and sibling_list. Previously it would iterate the group (sibling_list) first, and for each sibling traverse the child_list. In this order, only the group composition of the parent is relevant. By flipping the order the group composition of the child (inherited) events becomes an issue and the mis-match in group composition becomes evident. That said; even prior to this commit, while reading of a group that is not equally inherited was not broken, it still made no sense. (Ab)use ECHILD as error return to indicate issues with child process group composition.

2023-10-18net/sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curvePedro Tammela
Christian Theune says: I upgraded from 6.1.38 to 6.1.55 this morning and it broke my traffic shaping script, leaving me with a non-functional uplink on a remote router. A 'rt' curve cannot be used as a inner curve (parent class), but we were allowing such configurations since the qdisc was introduced. Such configurations would trigger a UAF as Budimir explains: The parent will have vttree_insert() called on it in init_vf(), but will not have vttree_remove() called on it in update_vf() because it does not have the HFSC_FSC flag set. The qdisc always assumes that inner classes have the HFSC_FSC flag set. This is by design as it doesn't make sense 'qdisc wise' for an 'rt' curve to be an inner curve. Budimir's original patch disallows users to add classes with a 'rt' parent, but this is too strict as it breaks users that have been using 'rt' as a inner class. Another approach, taken by this patch, is to upgrade the inner 'rt' into a 'sc', warning the user in the process. It avoids the UAF reported by Budimir while also being more permissive to bad scripts/users/code using 'rt' as a inner class. Users checking the `tc class ls [...]` or `tc class get [...]` dumps would observe the curve change and are potentially breaking with this change. v1->v2: https://lore.kernel.org/all/20231013151057.2611860-1-pctammela@mojatatu.com/ - Correct 'Fixes' tag and merge with revert (Jakub) Cc: Christian Theune <ct@flyingcircus.io> Cc: Budimir Markovic <markovicbudimir@gmail.com> Fixes: b3d26c5702c7 ("net/sched: sch_hfsc: Ensure inner classes have fsc curve") Signed-off-by: Pedro Tammela <pctammela@mojatatu.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Link: https://lore.kernel.org/r/20231017143602.3191556-1-pctammela@mojatatu.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-10-18net: mdio-mux: fix C45 access returning -EIO after API changeVladimir Oltean
The mii_bus API conversion to read_c45() and write_c45() did not cover the mdio-mux driver before read() and write() were made C22-only. This broke arch/arm64/boot/dts/freescale/fsl-ls1028a-qds-13bb.dtso. The -EOPNOTSUPP from mdiobus_c45_read() is transformed by get_phy_c45_devs_in_pkg() into -EIO, is further propagated to of_mdiobus_register() and this makes the mdio-mux driver fail to probe the entire child buses, not just the PHYs that cause access errors. Fix the regression by introducing special c45 read and write accessors to mdio-mux which forward the operation to the parent MDIO bus.

2023-10-18tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a single skbEric Dumazet
In commit 75eefc6c59fd ("tcp: tsq: add a shortcut in tcp_small_queue_check()") we allowed to send an skb regardless of TSQ limits being hit if rtx queue was empty or had a single skb, in order to better fill the pipe when/if TX completions were slow. Then later, commit 75c119afe14f ("tcp: implement rb-tree based retransmit queue") accidentally removed the special case for one skb in rtx queue. Stefan Wahren reported a regression in single TCP flow throughput using a 100Mbit fec link, starting from commit 65466904b015 ("tcp: adjust TSO packet sizes based on min_rtt"). This last commit only made the regression more visible, because it locked the TCP flow on a particular behavior where TSQ prevented two skbs being pushed downstream, adding silences on the wire between each TSO packet.

It may happen that the work to destroy a queue (for example nvmet_tcp_release_queue_work()) is started while an auth-send or auth-receive command is still completing. nvmet_sq_destroy() will block, waiting for all the references to the sq to be dropped, the last reference is then dropped when nvmet_req_complete() is called. When this happens, both nvmet_sq_destroy() and nvmet_execute_auth_send()/_receive() will free the dhchap pointers by calling nvmet_auth_sq_free().

This patches fixes commit 51d674a5e488 "NFSv4.1: use EXCHGID4_FLAG_USE_PNFS_DS for DS server", purpose of that commit was to mark EXCHANGE_ID to the DS with the appropriate flag. However, connection to MDS can return both EXCHGID4_FLAG_USE_PNFS_DS and EXCHGID4_FLAG_USE_PNFS_MDS set but previous patch would only remember the USE_PNFS_DS and for the 2nd EXCHANGE_ID send that to the MDS.

We are not allowed to call pnfs_mark_matching_lsegs_return() without also holding a reference to the layout header, since doing so could lead to the reference count going to zero when we call pnfs_layout_remove_lseg(). This again can lead to a hang when we get to nfs4_evict_inode() and are unable to clear the layout pointer. pnfs_layout_return_unused_byserver() is guilty of this behaviour, and has been seen to trigger the refcount warning prior to a hang.

Due to the initial confusion about MIPI_DSI_MODE_EOT_PACKET, properly renamed to MIPI_DSI_MODE_NO_EOT_PACKET, reflecting its actual meaning, both the DSI_TXRX_CON register setting for bit (HSTX_)DIS_EOT and the later calculation for horizontal sync-active (HSA), back (HBP) and front (HFP) porches got incorrect due to the logic being inverted. This means that a number of settings were wrong because....: - DSI_TXRX_CON register setting: bit (HSTX_)DIS_EOT should be set in order to disable the End of Transmission packet; - Horizontal Sync and Back/Front porches: The delta used to calculate all of HSA, HBP and HFP should account for the additional EOT packet. Before this change... - Bit (HSTX_)DIS_EOT was being set when EOT packet was enabled; - For HSA/HBP/HFP delta... all three were wrong, as words were added when EOT disabled, instead of when EOT packet enabled! Invert the logic around flag MIPI_DSI_MODE_NO_EOT_PACKET in the MediaTek DSI driver to fix the aforementioned issues.

2023-10-18powerpc/qspinlock: Fix stale propagated yield_cpuNicholas Piggin
yield_cpu is a sample of a preempted lock holder that gets propagated back through the queue. Queued waiters use this to yield to the preempted lock holder without continually sampling the lock word (which would defeat the purpose of MCS queueing by bouncing the cache line). The problem is that yield_cpu can become stale. It can take some time to be passed down the chain, and if any queued waiter gets preempted then it will cease to propagate the yield_cpu to later waiters. This can result in yielding to a CPU that no longer holds the lock, which is bad, but particularly if it is currently in H_CEDE (idle), then it appears to be preempted and some hypervisors (PowerVM) can cause very long H_CONFER latencies waiting for H_CEDE wakeup. This results in latency spikes and hard lockups on oversubscribed partitions with lock contention. This is a minimal fix. Before yielding to yield_cpu, sample the lock word to confirm yield_cpu is still the owner, and bail out of it is not. Thanks to a bunch of people who reported this and tracked down the exact problem using tracepoints and dispatch trace logs.

2023-10-18platform/x86: asus-wmi: Only map brightness codes when using asus-wmi ↵Hans de Goede
backlight control Older Asus laptops change the backlight level themselves and then send WMI events with different codes for different backlight levels. The asus-wmi.c code maps the entire range of codes reported on brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code: define NOTIFY_BRNUP_MIN 0x11 define NOTIFY_BRNUP_MAX 0x1f define NOTIFY_BRNDOWN_MIN 0x20 define NOTIFY_BRNDOWN_MAX 0x2e if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX) code = ASUS_WMI_BRN_UP; else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX) code = ASUS_WMI_BRN_DOWN; This mapping is causing issues on new laptop models which actually send 0x2b events for printscreen presses and 0x2c events for capslock presses, which get translated into spurious brightness-down presses. This mapping is really only necessary when asus-wmi has registered a backlight-device for backlight control. In this case the mapping was used to decide to filter out the keypresss since in this case the firmware has already modified the brightness itself and instead of reporting a keypress asus-wmi will just report the new brightness value to userspace. OTOH when the firmware does not adjust the brightness itself then it seems to always report 0x2e for brightness-down presses and 0x2f for brightness up presses independent of the actual brightness level. So in this case the mapping of the code is not necessary and this translation actually leads to spurious brightness-down presses being send to userspace when pressing printscreen or capslock. Modify asus_wmi_handle_event_code() to only do the mapping when using asus-wmi backlight control to fix the spurious brightness-down presses.

The plan is disable the 0x11-0x2e special mapping on laptops where asus-wmi does not register a backlight-device to avoid the spurious brightness-down keypresses. New laptops always send 0x2e for brightness-down presses, change the special internal ASUS_WMI_BRN_DOWN value from 0x20 to 0x2e to match this in preparation for fixing the spurious brightness-down presses. This change does not have any functional impact since all of 0x20 - 0x2e is mapped to ASUS_WMI_BRN_DOWN first and only then checked against the keymap code and the new 0x2e value is still in the 0x20 - 0x2e range.

2023-10-18net: pktgen: Fix interface flags printingGavrilov Ilia
Device flags are displayed incorrectly: 1) The comparison (i == F_FLOW_SEQ) is always false, because F_FLOW_SEQ is equal to (1 << FLOW_SEQ_SHIFT) == 2048, and the maximum value of the 'i' variable is (NR_PKT_FLAG - 1) == 17. It should be compared with FLOW_SEQ_SHIFT. 2) Similarly to the F_IPSEC flag. 3) Also add spaces to the print end of the string literal "spi:%u" to prevent the output from merging with the flag that follows. Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with SVACE.

We found a glitch when configuring the pad as output high. To avoid this glitch, move the data value setting before direction config in the function vf610_gpio_direction_output().

2023-10-18gpio: vf610: mask the gpio irq in system suspend and support wakeupHaibo Chen
Add flag IRQCHIP_MASK_ON_SUSPEND to make sure gpio irq is masked on suspend, if lack this flag, current irq arctitecture will not mask the irq, and these unmasked gpio irq will wrongly wakeup the system even they are not config as wakeup source. Also add flag IRQCHIP_ENABLE_WAKEUP_ON_SUSPEND to make sure the gpio irq which is configed as wakeup source can work as expect.

Because someone is a flaming idiot... and forgot we have current as se->on_rq but not actually in the tree itself, and walking rb_parent() on an entry not in the tree is 'funky' and KASAN complains.
