[for-linus][PATCH 3/3] tracing/histograms: Return an error if we fail to add histogram to hist_vars list

by Steven Rostedt

From: Mohamed Khalfella <mkhalfella(a)purestorage.com> Commit 6018b585e8c6 ("tracing/histograms: Add histograms to hist_vars if they have referenced variables") added a check to fail histogram creation if save_hist_vars() failed to add histogram to hist_vars list. But the commit failed to set ret to failed return code before jumping to unregister histogram, fix it.

[PATCH] kbuild: rust: avoid creating temporary files

by Miguel Ojeda

`rustc` outputs by default the temporary files (i.e. the ones saved by `-Csave-temps`, such as `*.rcgu*` files) in the current working directory when `-o` and `--out-dir` are not given (even if `--emit=x=path` is given, i.e. it does not use those for temporaries). Since out-of-tree modules are compiled from the `linux` tree, `rustc` then tries to create them there, which may not be accessible. Thus pass `--out-dir` explicitly, even if it is just for the temporary files.

However, the fix in this commit is wrong: the MODULE_DEVICE_TABLE(of, ....) is in the core part of the driver, not the I2C part. Therefore, automatic module loading based on module.alias, based on matching with the DT compatible string, loads the core part of the driver, but not the I2C part. And threfore, the i2c_driver is not registered, and the codec is not known to the system, nor matched with a DT node with the corresponding compatible string. In order to fix that, we move the MODULE_DEVICE_TABLE(of, ...) into the I2C part of the driver. The cs42l51_of_match[] array is also moved as well, as it is not possible to have this definition in one file, and the MODULE_DEVICE_TABLE(of, ...) invocation in another file, due to how MODULE_DEVICE_TABLE works. Thanks to this commit, the I2C part of the driver now properly autoloads, and thanks to its dependency on the core part, the core part gets autoloaded as well, resulting in a functional sound card without having to manually load kernel modules.

Which violates the spec and cause source can't send out streams to mst sinks. [How] To cover this misbehavior, add an additional polling method to detect DOWN_REP_MSG_RDY is set. HPD driven handling method is still kept. Just hook up our handler to drm mgr->cbs->poll_hpd_irq().

Which violates the spec and cause source can't send out streams to mst sinks. [How] To cover this misbehavior, add an additional polling method to detect DOWN_REP_MSG_RDY is set. HPD driven handling method is still kept. Just hook up our handler to drm mgr->cbs->poll_hpd_irq().

CPU1 CPU2 drm_crtc_vblank_off hrtimer_interrupt grab event_lock (irq disabled) __hrtimer_run_queues grab vbl_lock/vblank_time_block amdgpu_vkms_vblank_simulate amdgpu_vkms_disable_vblank drm_handle_vblank hrtimer_cancel grab dev->event_lock So CPU1 stucks in hrtimer_cancel as timer callback is running endless on current clock base, as that timer queue on CPU2 has no chance to finish it because of failing to hold the lock. So NMI watchdog will throw the errors after its threshold, and all later CPUs are impacted/blocked. So use hrtimer_try_to_cancel to fix this, as disable_vblank callback does not need to wait the handler to finish. And also it's not necessary to check the return value of hrtimer_try_to_cancel, because even if it's -1 which means current timer callback is running, it will be reprogrammed in hrtimer_start with calling enable_vblank to make it works. v2: only re-arm timer when vblank is enabled (Christian) and add a Fixes tag as well v3: drop warn printing (Christian) v4: drop superfluous check of blank->enabled in timer function, as it's guaranteed in drm_handle_vblank (Christian) Fixes: 84ec374bd580 ("drm/amdgpu: create amdgpu_vkms (v4)") Cc: stable(a)vger.kernel.org Suggested-by: Christian König <christian.koenig(a)amd.com> Signed-off-by: Guchun Chen <guchun.chen(a)amd.com> Reviewed-by: Christian König <christian.koenig(a)amd.com> Signed-off-by: Alex Deucher <alexander.deucher(a)amd.com> diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_vkms.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_vkms.c index 53ff91fc6cf6..d0748bcfad16 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_vkms.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_vkms.c @@ -55,8 +55,9 @@ static enum hrtimer_restart amdgpu_vkms_vblank_simulate(struct hrtimer *timer) DRM_WARN("%s: vblank timer overrun\n", __func__); ret = drm_crtc_handle_vblank(crtc); + /* Don't queue timer again when vblank is disabled. */ if (!ret) - DRM_ERROR("amdgpu_vkms failure on handling vblank"); + return HRTIMER_NORESTART; return HRTIMER_RESTART; } @@ -81,7 +82,7 @@ static void amdgpu_vkms_disable_vblank(struct drm_crtc *crtc) { struct amdgpu_crtc *amdgpu_crtc = to_amdgpu_crtc(crtc); - hrtimer_cancel(&amdgpu_crtc->vblank_timer); + hrtimer_try_to_cancel(&amdgpu_crtc->vblank_timer); } static bool amdgpu_vkms_get_vblank_timestamp(struct drm_crtc *crtc,

In gs_usb_disconnect() all pending bulk URBs are killed, i.e. no more RX'ed CAN frames are send from the USB device to the host. Later in gs_can_close() a reset control message is send to each CAN channel to remove the controller from the CAN bus. In this race window the USB device can still receive CAN frames from the bus and internally queue them to be send to the host. At least in the current version of the candlelight firmware, the queue of received CAN frames is not emptied during the reset command. After loading (or binding) the gs_usb driver, new URBs are submitted during the struct net_device_ops::ndo_open callback and the candlelight firmware starts sending its already queued CAN frames to the host. However, this scenario was not considered when implementing the hardware timestamp function. The cycle counter/time counter infrastructure is set up (gs_usb_timestamp_init()) after the USBs are submitted, resulting in a NULL pointer dereference if timecounter_cyc2time() (via the call chain: gs_usb_receive_bulk_callback() -> gs_usb_set_timestamp() -> gs_usb_skb_set_timestamp()) is called too early. Move the gs_usb_timestamp_init() function before the URBs are submitted to fix this problem. For a comprehensive solution, we need to consider gs_usb devices with more than 1 channel. The cycle counter/time counter infrastructure is setup per channel, but the RX URBs are per device. Once gs_can_open() of _a_ channel has been called, and URBs have been submitted, the gs_usb_receive_bulk_callback() can be called for _all_ available channels, even for channels that are not running, yet. As cycle counter/time counter has not set up, this will again lead to a NULL pointer dereference. Convert the cycle counter/time counter from a "per channel" to a "per device" functionality. Also set it up, before submitting any URBs to the device. Further in gs_usb_receive_bulk_callback(), don't process any URBs for not started CAN channels, only resubmit the URB.

The maximum length of a CAN frame is 736 bits (64 data bytes, CAN-FD, EFF mode, worst case bit stuffing and interframe spacing). For low bit rates like 10 kbit/s the arbitrarily chosen MCP251XFD_POLL_TIMEOUT_US of 1 ms is too small. Otherwise during polling for the CAN controller to enter 'Normal CAN 2.0 mode' the timeout limit is exceeded and the configuration fails with: | $ ip link set dev can1 up type can bitrate 10000 | [ 731.911072] mcp251xfd spi2.1 can1: Controller failed to enter mode CAN 2.0 Mode (6) and stays in Configuration Mode (4) (con=0x068b0760, osc=0x00000468). | [ 731.927192] mcp251xfd spi2.1 can1: CRC read error at address 0x0e0c (length=4, data=00 00 00 00, CRC=0x0000) retrying. | [ 731.938101] A link change request failed with some changes committed already. Interface can1 may have been left with an inconsistent configuration, please check. | RTNETLINK answers: Connection timed out Make MCP251XFD_POLL_TIMEOUT_US timeout calculation dynamic. Use maximum of 1ms and bit time of 1 full 64 data bytes CAN-FD frame in EFF mode, worst case bit stuffing and interframe spacing at the current bit rate. For easier backporting define the macro MCP251XFD_FRAME_LEN_MAX_BITS that holds the max frame length in bits, which is 736. This can be replaced by can_frame_bits(true, true, true, true, CANFD_MAX_DLEN) in a cleanup patch later.

This has two consequences: 1) We move it out of the list of new block groups associated to the current transaction. So the block group creation is not finished and if we attempt to delete the bg because it's unused, we will not find the block group item in the extent tree (or the new block group tree), its device extent items in the device tree etc, resulting in the deletion to fail due to the missing items; 2) We don't increment the reference count on the block group when we move it to the list of unused block groups, because we assumed the block group was on the list of block groups to reclaim, and in that case it already has the correct reference count. However the block group was on the list of new block groups, in which case no extra reference was taken because it's local to the current task. This later results in doing an extra reference count decrement when removing the block group from the unused list, eventually leading the reference count to 0. This second case was caught when running generic/297 from fstests, which produced the following assertion failure and stack trace: [589.559] assertion failed: refcount_read(&block_group->refs) == 1, in fs/btrfs/block-group.c:4299 [589.559] ------------[ cut here ]------------ [589.559] kernel BUG at fs/btrfs/block-group.c:4299!

This has two consequences: 1) We move it out of the list of new block groups associated to the current transaction. So the block group creation is not finished and if we attempt to delete the bg because it's unused, we will not find the block group item in the extent tree (or the new block group tree), its device extent items in the device tree etc, resulting in the deletion to fail due to the missing items; 2) We don't increment the reference count on the block group when we move it to the list of unused block groups, because we assumed the block group was on the list of block groups to reclaim, and in that case it already has the correct reference count. However the block group was on the list of new block groups, in which case no extra reference was taken because it's local to the current task. This later results in doing an extra reference count decrement when removing the block group from the unused list, eventually leading the reference count to 0.

Howlett" <Liam.Howlett(a)oracle.com> Date: Wed, 12 Jul 2023 13:39:15 -0400 Subject: [PATCH] maple_tree: fix 32 bit mas_next testing The test setup of mas_next is dependent on node entry size to create a 2 level tree, but the tests did not account for this in the expected value when shifting beyond the scope of the tree. Fix this by setting up the test to succeed depending on the node entries which is dependent on the 32/64 bit setup.

[PATCH] x86/cpu: Enable STIBP if Automatic IBRS is enabled

by Kim Phillips

Unlike Intel's Enhanced IBRS feature, AMD's Automatic IBRS does not provide protection to processes running at CPL3/user mode [1]. Explicitly enable STIBP to protect against cross-thread CPL3 branch target injections on systems with Automatic IBRS enabled. Also update the relevant documentation. The first version of the original AutoIBRS patchseries enabled STIBP always-on, but it got dropped by mistake in v2 and on.

This can be the case if referenced variables are added for trigger actions. In this case the newly added references will not have field variables. Not taking such referenced variables into consideration can result in a bug where it would be possible to remove hist trigger with variables being refenced. This will result in a bug that is easily reproducable like so $ cd /sys/kernel/tracing $ echo 'synthetic_sys_enter char[] comm; long id' >> synthetic_events $ echo 'hist:keys=common_pid.execname,id.syscall:vals=hitcount:comm=common_pid.execname' >> events/raw_syscalls/sys_enter/trigger $ echo 'hist:keys=common_pid.execname,id.syscall:onmatch(raw_syscalls.sys_enter).synthetic_sys_enter($comm, id)' >> events/raw_syscalls/sys_enter/trigger $ echo '!hist:keys=common_pid.execname,id.syscall:vals=hitcount:comm=common_pid.execname' >> events/raw_syscalls/sys_enter/trigger [ 100.263533] ================================================================== [ 100.264634] BUG: KASAN: slab-use-after-free in resolve_var_refs+0xc7/0x180 [ 100.265520] Read of size 8 at addr ffff88810375d0f0 by task bash/439 [ 100.266320] [ 100.266533] CPU: 2 PID: 439 Comm: bash Not tainted 6.5.0-rc1 #4 [ 100.267277] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.0-20220807_005459-localhost 04/01/2014 [ 100.268561] Call Trace: [ 100.268902] <TASK> [ 100.269189] dump_stack_lvl+0x4c/0x70 [ 100.269680] print_report+0xc5/0x600 [ 100.270165] ? resolve_var_refs+0xc7/0x180 [ 100.270697] ? kasan_complete_mode_report_info+0x80/0x1f0 [ 100.271389] ? resolve_var_refs+0xc7/0x180 [ 100.271913] kasan_report+0xbd/0x100 [ 100.272380] ? resolve_var_refs+0xc7/0x180 [ 100.272920] __asan_load8+0x71/0xa0 [ 100.273377] resolve_var_refs+0xc7/0x180 [ 100.273888] event_hist_trigger+0x749/0x860 [ 100.274505] ? kasan_save_stack+0x2a/0x50 [ 100.275024] ? kasan_set_track+0x29/0x40 [ 100.275536] ? __pfx_event_hist_trigger+0x10/0x10 [ 100.276138] ? ksys_write+0xd1/0x170 [ 100.276607] ? do_syscall_64+0x3c/0x90 [ 100.277099] ? entry_SYSCALL_64_after_hwframe+0x6e/0xd8 [ 100.277771] ? destroy_hist_data+0x446/0x470 [ 100.278324] ? event_hist_trigger_parse+0xa6c/0x3860 [ 100.278962] ? __pfx_event_hist_trigger_parse+0x10/0x10 [ 100.279627] ? __kasan_check_write+0x18/0x20 [ 100.280177] ? mutex_unlock+0x85/0xd0 [ 100.280660] ? __pfx_mutex_unlock+0x10/0x10 [ 100.281200] ? kfree+0x7b/0x120 [ 100.281619] ? ____kasan_slab_free+0x15d/0x1d0 [ 100.282197] ? event_trigger_write+0xac/0x100 [ 100.282764] ? __kasan_slab_free+0x16/0x20 [ 100.283293] ? __kmem_cache_free+0x153/0x2f0 [ 100.283844] ? sched_mm_cid_remote_clear+0xb1/0x250 [ 100.284550] ? __pfx_sched_mm_cid_remote_clear+0x10/0x10 [ 100.285221] ? event_trigger_write+0xbc/0x100 [ 100.285781] ? __kasan_check_read+0x15/0x20 [ 100.286321] ? __bitmap_weight+0x66/0xa0 [ 100.286833] ? _find_next_bit+0x46/0xe0 [ 100.287334] ? task_mm_cid_work+0x37f/0x450 [ 100.287872] event_triggers_call+0x84/0x150 [ 100.288408] trace_event_buffer_commit+0x339/0x430 [ 100.289073] ? ring_buffer_event_data+0x3f/0x60 [ 100.292189] trace_event_raw_event_sys_enter+0x8b/0xe0 [ 100.295434] syscall_trace_enter.constprop.0+0x18f/0x1b0 [ 100.298653] syscall_enter_from_user_mode+0x32/0x40 [ 100.301808] do_syscall_64+0x1a/0x90 [ 100.304748] entry_SYSCALL_64_after_hwframe+0x6e/0xd8 [ 100.307775] RIP: 0033:0x7f686c75c1cb [ 100.310617] Code: 73 01 c3 48 8b 0d 65 3c 10 00 f7 d8 64 89 01 48 83 c8 ff c3 66 2e 0f 1f 84 00 00 00 00 00 90 f3 0f 1e fa b8 21 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 35 3c 10 00 f7 d8 64 89 01 48 [ 100.317847] RSP: 002b:00007ffc60137a38 EFLAGS: 00000246 ORIG_RAX: 0000000000000021 [ 100.321200] RAX: ffffffffffffffda RBX: 000055f566469ea0 RCX: 00007f686c75c1cb [ 100.324631] RDX: 0000000000000001 RSI: 0000000000000001 RDI: 000000000000000a [ 100.328104] RBP: 00007ffc60137ac0 R08: 00007f686c818460 R09: 000000000000000a [ 100.331509] R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000009 [ 100.334992] R13: 0000000000000007 R14: 000000000000000a R15: 0000000000000007 [ 100.338381] </TASK> We hit the bug because when second hist trigger has was created has_hist_vars() returned false because hist trigger did not have variables. As a result of that save_hist_vars() was not called to add the trigger to trace_array->hist_vars. Later on when we attempted to remove the first histogram find_any_var_ref() failed to detect it is being used because it did not find the second trigger in hist_vars list. With this change we wait until trigger actions are created so we can take into consideration if hist trigger has variable references. Also, now we check the return value of save_hist_vars() and fail trigger creation if save_hist_vars() fails.

[PATCH 1/3] HID: wacom: remove the battery when the EKR is off

by Aaron Armstrong Skomra

From: Aaron Armstrong Skomra <aaron.skomra(a)wacom.com> Currently the EKR battery remains even after we stop getting information from the device. This can lead to a stale battery persisting indefinitely in userspace. The remote sends a heartbeat every 10 seconds. Delete the battery if we miss two heartbeats (after 21 seconds). Restore the battery once we see a heartbeat again.

[PATCH 1/1] x86/hyperv: Disable IBT when hypercall page lacks ENDBR instruction

by Michael Kelley

On hardware that supports Indirect Branch Tracking (IBT), Hyper-V VMs with ConfigVersion 9.3 or later support IBT in the guest. However, current versions of Hyper-V have a bug in that there's not an ENDBR64 instruction at the beginning of the hypercall page. Since hypercalls are made with an indirect call to the hypercall page, all hypercall attempts fail with an exception and Linux panics. A Hyper-V fix is in progress to add ENDBR64. But guard against the Linux panic by clearing X86_FEATURE_IBT if the hypercall page doesn't start with ENDBR. The VM will boot and run without IBT. If future Linux 32-bit kernels were to support IBT, additional hypercall page hackery would be needed to make IBT work for such kernels in a Hyper-V VM.

[RESEND PATCH v8 07/10] serial: sc16is7xx: fix bug when first setting GPIO direction

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> When configuring a pin as an output pin with a value of logic 0, we end up as having a value of logic 1 on the output pin. Setting a logic 0 a second time (or more) after that will correctly output a logic 0 on the output pin. By default, all GPIO pins are configured as inputs. When we enter sc16is7xx_gpio_direction_output() for the first time, we first set the desired value in IOSTATE, and then we configure the pin as an output. The datasheet states that writing to IOSTATE register will trigger a transfer of the value to the I/O pin configured as output, so if the pin is configured as an input, nothing will be transferred. Therefore, set the direction first in IODIR, and then set the desired value in IOSTATE. This is what is done in NXP application note AN10587.

[RESEND PATCH v8 02/10] serial: sc16is7xx: mark IOCONTROL register as volatile

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Bit SRESET (3) is cleared when a reset operation is completed. Having the IOCONTROL register as non-volatile will always read SRESET as 1, which is incorrect. Also, if IOCONTROL register is not a volatile register, the upcoming patch "serial: sc16is7xx: fix regression with GPIO configuration" doesn't work when setting some shared GPIO lines as modem control lines. Therefore mark IOCONTROL register as a volatile register.

[RESEND PATCH v8 01/10] serial: sc16is7xx: fix broken port 0 uart init

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> The sc16is7xx_config_rs485() function is called only for the second port (index 1, channel B), causing initialization problems for the first port. For the sc16is7xx driver, port->membase and port->mapbase are not set, and their default values are 0. And we set port->iobase to the device index. This means that when the first device is registered using the uart_add_one_port() function, the following values will be in the port structure: port->membase = 0 port->mapbase = 0 port->iobase = 0 Therefore, the function uart_configure_port() in serial_core.c will exit early because of the following check: /* * If there isn't a port here, don't do anything further. */ if (!port->iobase && !port->mapbase && !port->membase) return; Typically, I2C and SPI drivers do not set port->membase and port->mapbase. The max310x driver sets port->membase to ~0 (all ones). By implementing the same change in this driver, uart_configure_port() is now correctly executed for all ports.

[PATCH v7 5/9] serial: sc16is7xx: fix regression with GPIO configuration

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Commit 679875d1d880 ("sc16is7xx: Separate GPIOs from modem control lines") and commit 21144bab4f11 ("sc16is7xx: Handle modem status lines") changed the function of the GPIOs pins to act as modem control lines without any possibility of selecting GPIO function. As a consequence, applications that depends on GPIO lines configured by default as GPIO pins no longer work as expected. Also, the change to select modem control lines function was done only for channel A of dual UART variants (752/762). This was not documented in the log message. Allow to specify GPIO or modem control line function in the device tree, and for each of the ports (A or B). Do so by using the new device-tree property named "modem-control-line-ports" (property added in separate patch). When registering GPIO chip controller, mask-out GPIO pins declared as modem control lines according to this new "modem-control-line-ports" DT property. Boards that need to have GPIOS configured as modem control lines should add that property to their device tree. Here is a list of boards using the sc16is7xx driver in their device tree and that may need to be modified: arm64/boot/dts/freescale/fsl-ls1012a-frdm.dts mips/boot/dts/ingenic/cu1830-neo.dts mips/boot/dts/ingenic/cu1000-neo.dts Fixes: 679875d1d880 ("sc16is7xx: Separate GPIOs from modem control lines") Fixes: 21144bab4f11 ("sc16is7xx: Handle modem status lines") Cc: <stable(a)vger.kernel.org> # 6.1.x: 35210b22 dt-bindings: sc16is7xx: Add property to change GPIO function Cc: <stable(a)vger.kernel.org> # 6.1.x: 7d61ca47 serial: sc16is7xx: refactor GPIO controller registration Cc: <stable(a)vger.kernel.org> # 6.1.x: 322470ed serial: sc16is7xx: mark IOCONTROL register as volatile Cc: <stable(a)vger.kernel.org> # 6.1.x: a0077362 serial: sc16is7xx: fix broken port 0 uart init Cc: <stable(a)vger.kernel.org> # 6.1.x Signed-off-by: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Reviewed-by: Andy Shevchenko <andy.shevchenko(a)gmail.com> --- drivers/tty/serial/sc16is7xx.c | 103 ++++++++++++++++++++++++++------- 1 file changed, 82 insertions(+), 21 deletions(-) diff --git a/drivers/tty/serial/sc16is7xx.c b/drivers/tty/serial/sc16is7xx.c index 7d50674d2d0e..edc83f5f6340 100644 --- a/drivers/tty/serial/sc16is7xx.c +++ b/drivers/tty/serial/sc16is7xx.c @@ -236,7 +236,8 @@ /* IOControl register bits (Only 750/760) */ #define SC16IS7XX_IOCONTROL_LATCH_BIT (1 << 0) /* Enable input latching */ -#define SC16IS7XX_IOCONTROL_MODEM_BIT (1 << 1) /* Enable GPIO[7:4] as modem pins */ +#define SC16IS7XX_IOCONTROL_MODEM_A_BIT (1 << 1) /* Enable GPIO[7:4] as modem A pins */ +#define SC16IS7XX_IOCONTROL_MODEM_B_BIT (1 << 2) /* Enable GPIO[3:0] as modem B pins */ #define SC16IS7XX_IOCONTROL_SRESET_BIT (1 << 3) /* Software Reset */ /* EFCR register bits */ @@ -301,12 +302,12 @@ /* Misc definitions */ #define SC16IS7XX_FIFO_SIZE (64) #define SC16IS7XX_REG_SHIFT 2 +#define SC16IS7XX_GPIOS_PER_BANK 4 struct sc16is7xx_devtype { char name[10];

[PATCH AUTOSEL 6.4 01/12] platform/chrome: cros_ec: Report EC panic as uevent

by Sasha Levin

From: Rob Barnes <robbarnes(a)google.com> [ Upstream commit 2cbf475a04b2ae3d722bbe41742e5d874a027fc3 ] Create a uevent when an EC panic is detected. This will allow udev rules to trigger when a panic occurs. For example, a udev rule could be added to capture an EC coredump. This approach avoids the need to stuff all the processing into the driver.

[PATCH 5.10 0/1] RDMA/cma: Ensure rdma_addr_cancel() happens before issuing more requests

by Anton Gusev

Syzkaller reports use-after-free at addr_handler in 5.10 stable releases. The problem was fixed in upstream and backported into 5.14, but wasn't applied to 5.10 and lower versions due to a small merge conflict. This patch is a modified version that can be cleanly applied to 5.10 and 5.4 stable branches. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Currently those expect that the data_loc is updated by store_trace_args() if it returns the error code. However, that does not work correctly if the argument is an array of strings. In that case, store_trace_args() only clears the first entry of the array (which may have no error) and leaves other entries. So it should be cleared by fetch_store_string*() itself. Also, 'dyndata' and 'maxlen' in store_trace_args() should be updated only if it is used (ret > 0 and argument is a dynamic data.)

[5.10, 5.15] New bpf kselftest failure

by Luiz Capitulino

Hi, The upstream commit below is backported to 5.10.186, 5.15.120 and 6.1.36: """ commit ecdf985d7615356b78241fdb159c091830ed0380 Author: Eduard Zingerman <eddyz87(a)gmail.com> Date: Wed Feb 15 01:20:27 2023 +0200 bpf: track immediate values written to stack by BPF_ST instruction """ This commit is causing the following bpf:test_verifier kselftest to fail: """ # #760/p precise: ST insn causing spi > allocated_stack FAIL """ Since this test didn't fail before ecdf985d76 backport, the question is if this is a test bug or if this commit introduced a regression. I haven't checked if this failure is present in latest Linus tree because I was unable to build & run the bpf kselftests in an older distro. Also, there some important details about running the bpf kselftests in 5.10 and 5.15: * On 5.10, bpf kselftest build is broken. The following upstream commit needs to be cherry-picked for it to build & run: """ commit 4237e9f4a96228ccc8a7abe5e4b30834323cd353 Author: Gilad Reti <gilad.reti(a)gmail.com> Date: Wed Jan 13 07:38:08 2021 +0200 selftests/bpf: Add verifier test for PTR_TO_MEM spill """ * On 5.15.120 there's one additional test that's failing, but I didn't debug this one: """ #150/p calls: trigger reg2btf_ids[reg→type] for reg→type > __BPF_REG_TYPE_MAX FAIL FAIL """ * On 5.11 onwards, building and running bpf tests is disabled by default by commit 7a6eb7c34a78498742b5f82543b7a68c1c443329, so I wonder if we want to backport this to 5.10 as well?

We should disable expanding the windows if the readahead is disabled and also shouldn't expand the windows too much. Expanding forward firstly instead of expanding backward for possible sequential reads. Bound `rreq->len` to the actual file size to restore the previous page cache usage. The posix_fadvise may change the maximum size of a file readahead.

[PATCH v7 0/9] Update AUX invalidation sequence

by Andi Shyti

Hi, as there are new hardware directives, we need a little adaptation for the AUX invalidation sequence. In this version we support all the engines affected by this change. The stable backport has some challenges because the original patch that this series fixes has had more changes in between. This patch is slowly exploding with code refactorings and features added and fixed. Thanks a lot Nirmoy, Andrzej and Matt for your review and for the fruitful discussions! Thanks, Andi Changelog: ========= v6 -> v7 - Fix correct sequence applied to the correct engine. A little confusion promptly cought by Nirmoy when applying to the VD engine the sequence belonging to the compute engines. Thanks a lot, Nirmoy! v5 -> v6 - Fixed ccs flush in the engines VE and BCS. They are sent as a separate command instead of added in the pipe control. - Separated the CCS flusing in the pipe control patch with the quiescing of the memory. They were meant to be on separate patch already in the previous verision, but apparently I squashed them by mistake. v4 -> v5 - The AUX CCS is added as a device property instead of checking against FLAT CCS. This adds the new HAS_AUX_CCS check (Patch 2, new). - little and trivial refactoring here and there. - extended the flags{0,1}/bit_group_{0,1} renaming to other functions. - Created an intel_emit_pipe_control_cs() wrapper for submitting the pipe control. - Quiesce memory for all the engines, not just RCS (Patch 6, new). - The PIPE_CONTROL_CCS_FLUSH is added to all the engines. - Remove redundant EMIT_FLUSH_CCS mode flag. - Remove unnecessary NOOPs from the command streamer for invalidating the CCS table. - Use INVALID_MMIO_REG and gen12_get_aux_inv_reg() instad of __MMIO(0) and reg.reg. - Remove useless wrapper and just use gen12_get_aux_inv_reg(). v3 -> v4 - A trivial patch 3 is added to rename the flags with bit_group_{0,1} to align with the datasheet naming. - Patch 4 fixes a confusion I made where the CCS flag was applied to the wrong bit group. v2 -> v3 - added r-b from Nirmoy in patch 1 and 4. - added patch 3 which enables the ccs_flush in the control pipe for mtl+ compute and render engines. - added redundant checks in patch 2 for enabling the EMIT_FLUSH flag. v1 -> v2 - add a clean up preliminary patch for the existing registers - add support for more engines - add the Fixes tag Andi Shyti (7): drm/i915/gt: Cleanup aux invalidation registers drm/i915: Add the has_aux_ccs device property drm/i915/gt: Rename flags with bit_group_X according to the datasheet drm/i915/gt: Enable the CCS_FLUSH bit in the pipe control drm/i915/gt: Refactor intel_emit_pipe_control_cs() in a single function drm/i915/gt: Ensure memory quiesced before invalidation for all engines drm/i915/gt: Support aux invalidation on all engines Jonathan Cavitt (2): drm/i915/gt: Ensure memory quiesced before invalidation drm/i915/gt: Poll aux invalidation register bit on invalidation drivers/gpu/drm/i915/gt/gen8_engine_cs.c | 188 ++++++++++++------- drivers/gpu/drm/i915/gt/gen8_engine_cs.h | 21 ++- drivers/gpu/drm/i915/gt/intel_gpu_commands.h | 2 + drivers/gpu/drm/i915/gt/intel_gt_regs.h | 16 +- drivers/gpu/drm/i915/gt/intel_lrc.c | 17 +- drivers/gpu/drm/i915/i915_drv.h | 1 + drivers/gpu/drm/i915/i915_pci.c | 5 +- drivers/gpu/drm/i915/intel_device_info.h | 1 + 8 files changed, 151 insertions(+), 100 deletions(-) -- 2.40.1

This fixes random GPU hangs when replacing sparse mappings from the userspace, while OP_MAP/OP_UNMAP works fine because always valid BOs are correctly handled there.

[PATCHv2 bpf 1/2] bpf: Disable preemption in bpf_perf_event_output

by Jiri Olsa

The nesting protection in bpf_perf_event_output relies on disabled preemption, which is guaranteed for kprobes and tracepoints. However bpf_perf_event_output can be also called from uprobes context through bpf_prog_run_array_sleepable function which disables migration, but keeps preemption enabled. This can cause task to be preempted by another one inside the nesting protection and lead eventually to two tasks using same perf_sample_data buffer and cause crashes like: kernel tried to execute NX-protected page - exploit attempt? (uid: 0) BUG: unable to handle page fault for address: ffffffff82be3eea ... Call Trace: ? __die+0x1f/0x70 ? page_fault_oops+0x176/0x4d0 ? exc_page_fault+0x132/0x230 ? asm_exc_page_fault+0x22/0x30 ? perf_output_sample+0x12b/0x910 ? perf_event_output+0xd0/0x1d0 ? bpf_perf_event_output+0x162/0x1d0 ? bpf_prog_c6271286d9a4c938_krava1+0x76/0x87 ? __uprobe_perf_func+0x12b/0x540 ? uprobe_dispatcher+0x2c4/0x430 ? uprobe_notify_resume+0x2da/0xce0 ? atomic_notifier_call_chain+0x7b/0x110 ? exit_to_user_mode_prepare+0x13e/0x290 ? irqentry_exit_to_user_mode+0x5/0x30 ? asm_exc_int3+0x35/0x40 Fixing this by disabling preemption in bpf_perf_event_output.

The problem was caused by a race between reader and kworker: n_tty_read(reader): n_tty_receive_buf_common(kworker): copy_from_read_buf()| |room = N_TTY_BUF_SIZE - (ldata->read_head - tail) |room <= 0 n_tty_kick_worker() | |ldata->no_room = true After writing to slave device, writer wakes up kworker to flush data on tty_port to reader, and the kworker finds that reader has no room to store data so room <= 0 is met. At this moment, reader consumes all the data on reader buffer and calls n_tty_kick_worker to check ldata->no_room which is false and reader quits reading. Then kworker sets ldata->no_room=true and quits too. If write buffer is not full, writer will wake kworker to flush data again after following writes, but if write buffer is full and writer goes to sleep, kworker will never be woken again and tty device is blocked. This problem can be solved with a check for read buffer size inside n_tty_receive_buf_common, if read buffer is empty and ldata->no_room is true, a call to n_tty_kick_worker is necessary to keep flushing data to reader.

If write buffer is not full, writer will wake kworker to flush data again after following writes, but if write buffer is full and writer goes to sleep, kworker will never be woken again and tty device is blocked.
