[PATCH v5.10] powerpc/uaccess: Fix build errors seen with GCC 13/14

by Michael Ellerman

commit 2d43cc701b96f910f50915ac4c2a0cae5deb734c upstream. Building ppc64le_defconfig with GCC 14 fails with assembler errors: CC fs/readdir.o /tmp/ccdQn0mD.s: Assembler messages: /tmp/ccdQn0mD.s:212: Error: operand out of domain (18 is not a multiple of 4) /tmp/ccdQn0mD.s:226: Error: operand out of domain (18 is not a multiple of 4) ... [6 lines] /tmp/ccdQn0mD.s:1699: Error: operand out of domain (18 is not a multiple of 4) A snippet of the asm shows: # ../fs/readdir.c:210: unsafe_copy_dirent_name(dirent->d_name, name, namlen, efault_end); ld 9,0(29) # MEM[(u64 *)name_38(D) + _88 * 1], MEM[(u64 *)name_38(D) + _88 * 1] # 210 "../fs/readdir.c" 1 1: std 9,18(8) # put_user # *__pus_addr_52, MEM[(u64 *)name_38(D) + _88 * 1] The 'std' instruction requires a 4-byte aligned displacement because it is a DS-form instruction, and as the assembler says, 18 is not a multiple of 4. A similar error is seen with GCC 13 and CONFIG_UBSAN_SIGNED_WRAP=y. The fix is to change the constraint on the memory operand to put_user(), from "m" which is a general memory reference to "YZ". The "Z" constraint is documented in the GCC manual PowerPC machine constraints, and specifies a "memory operand accessed with indexed or indirect addressing". "Y" is not documented in the manual but specifies a "memory operand for a DS-form instruction". Using both allows the compiler to generate a DS-form "std" or X-form "stdx" as appropriate. Unfortunately clang doesn't support the "Y" constraint so that has to be behind an ifdef. Although the build error is only seen with GCC 13/14, that appears to just be luck. The constraint has been incorrect since it was first added.

Xinput Controllers No Longer Working

by Edward Wawrzynski

Good Morning, I was reaching out to report that there's been a regression in the latest stable 6.9.4 kernel. I'm using Fedora 40 and 6.9.4 just got pushed to the repos recently. Upon updating, my wired USB Xinput controllers no longer get detected. I've tried two 8BitDo controllers, the one being the 8BitDo Pro 2 Bluetooth (with a USB cable) and the other being the 8BitDo Pro 2 Wired Controller for Xbox. Neither of them are being detected on Kernel 6.9.4, despite previously working throughout the lifetime of Fedora 40's 6.8.x kernel versions, the latest being 6.8.11. I've also tried the vanilla kernel, as well as the latest vanilla mainline kernel from Fedora's COPR: 6.10.0-0.rc4.337.vanilla.fc40.x86_64. To reproduce, simply load Kernel 6.9.4+ and plug a USB controller in with XInput (either an Xbox controller or something else that emulates one). It won't be detected. I plugged in a PS5 controller and it worked, but when I plugged in an Xbox Series S controller, it didn't work. The 8BitDo Pro 2 Bluetooth controller has four different settings (Switch, Android, DirectInput, Xinput), and it was detected and worked on every setting except for the Xinput setting. Reverting to version 6.8.11 fixes the issues immediately. -- Respectfully, Edward Wawrzynski

[PATCH 2/3] udf: Avoid using corrupted block bitmap buffer

by Jan Kara

When the filesystem block bitmap is corrupted, we detect the corruption while loading the bitmap and fail the allocation with error. However the next allocation from the same bitmap will notice the bitmap buffer is already loaded and tries to allocate from the bitmap with mixed results (depending on the exact nature of the bitmap corruption). Fix the problem by using BH_verified bit to indicate whether the bitmap is valid or not.

[PATCH AUTOSEL 6.1 01/29] scsi: core: alua: I/O errors for ALUA state transitions

by Sasha Levin

From: Martin Wilck <martin.wilck(a)suse.com> [ Upstream commit 10157b1fc1a762293381e9145041253420dfc6ad ] When a host is configured with a few LUNs and I/O is running, injecting FC faults repeatedly leads to path recovery problems. The LUNs have 4 paths each and 3 of them come back active after say an FC fault which makes 2 of the paths go down, instead of all 4. This happens after several iterations of continuous FC faults. Reason here is that we're returning an I/O error whenever we're encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC ACCESS STATE TRANSITION) instead of retrying. [mwilck: The original patch was developed by Rajashekhar M A and Hannes Reinecke. I moved the code to alua_check_sense() as suggested by Mike Christie [1]. Evan Milne had raised the question whether pg->state should be set to transitioning in the UA case [2]. I believe that doing this is correct. SCSI_ACCESS_STATE_TRANSITIONING by itself doesn't cause I/O errors. Our handler schedules an RTPG, which will only result in an I/O error condition if the transitioning timeout expires.] [1] https://lore.kernel.org/all/0bc96e82-fdda-4187-148d-5b34f81d4942@oracle.com/ [2] https://lore.kernel.org/all/CAGtn9r=kicnTDE2o7Gt5Y=yoidHYD7tG8XdMHEBJTBraVE… Co-developed-by: Rajashekhar M A <rajs(a)netapp.com> Co-developed-by: Hannes Reinecke <hare(a)suse.de> Signed-off-by: Hannes Reinecke <hare(a)suse.de> Signed-off-by: Martin Wilck <martin.wilck(a)suse.com> Link: https://lore.kernel.org/r/20240514140344.19538-1-mwilck@suse.com Reviewed-by: Damien Le Moal <dlemoal(a)kernel.org> Reviewed-by: Christoph Hellwig <hch(a)lst.de> Reviewed-by: Mike Christie <michael.christie(a)oracle.com> Signed-off-by: Martin K.

[PATCH] usb: typec: ucsi: glink: fix child node release in probe function

by Javier Carrasco

The device_for_each_child_node() macro requires explicit calls to fwnode_handle_put() in all early exits of the loop if the child node is not required outside. Otherwise, the child node's refcount is not decremented and the resource is not released. The current implementation of pmic_glink_ucsi_probe() makes use of the device_for_each_child_node(), but does not release the child node on early returns. Add the missing calls to fwnode_handle_put(). Cc: stable(a)vger.kernel.org Fixes: c6165ed2f425 ("usb: ucsi: glink: use the connector orientation GPIO to provide switch events") Signed-off-by: Javier Carrasco <javier.carrasco.cruz(a)gmail.com> --- This case would be a great opportunity for the recently introduced device_for_each_child_node_scoped(), but given that it has not been released yet, the traditional approach has been used to account for stable kernels (bug introduced with v6.7). A second patch to clean this up with that macro is ready to be sent once this fix is applied, so this kind of problem does not arise if more early returns are added. This issue has been found while analyzing the code and not tested with hardware, only compiled and checked with static analysis tools. Any tests with real hardware are always welcome. --- drivers/usb/typec/ucsi/ucsi_glink.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/usb/typec/ucsi/ucsi_glink.c b/drivers/usb/typec/ucsi/ucsi_glink.c index f7546bb488c3..41375e0f9280 100644 --- a/drivers/usb/typec/ucsi/ucsi_glink.c +++ b/drivers/usb/typec/ucsi/ucsi_glink.c @@ -372,6 +372,7 @@ static int pmic_glink_ucsi_probe(struct auxiliary_device *adev, ret = fwnode_property_read_u32(fwnode, "reg", &port); if (ret < 0) { dev_err(dev, "missing reg property of %pOFn\n", fwnode); + fwnode_handle_put(fwnode); return ret; } @@ -386,9 +387,11 @@ static int pmic_glink_ucsi_probe(struct auxiliary_device *adev, if (!desc) continue; - if (IS_ERR(desc)) + if (IS_ERR(desc)) { + fwnode_handle_put(fwnode); return dev_err_probe(dev, PTR_ERR(desc), "unable to acquire orientation gpio\n"); + } ucsi->port_orientation[port] = desc; } --- base-commit: 83a7eefedc9b56fe7bfeff13b6c7356688ffa670 change-id: 20240613-ucsi-glink-release-node-9fc09d81e138 Best regards, -- Javier Carrasco <javier.carrasco.cruz(a)gmail.com>

[PATCH 03/23] irqdomain: Fixed unbalanced fwnode get and put

by Herve Codina

fwnode_handle_get(fwnode) is called when a domain is created with fwnode passed as a function parameter. fwnode_handle_put(domain->fwnode) is called when the domain is destroyed but during the creation a path exists that does not set domain->fwnode. If this path is taken, the fwnode get will never be put. To avoid the unbalanced get and put, set domain->fwnode unconditionally.
