If starting the transfer of a command suceeds but the transfer for the reply fails, it is not enough to initiate killing the transfer for the command may still be running. You need to wait for the killing to finish before you can reuse URB and buffer.

2019-11-13nfc: pn533: pn533_phy_ops dev_[up, down] return intLars Poeschel
Change dev_up and dev_down functions of struct pn533_phy_ops to return int. This way the pn533 core can report errors in the phy layer to upper layers. The only user of this is currently uart.c and it is changed to report the error of a possibly failing call to serdev_device_open.

2019-11-11NFC: nxp-nci: Fix NULL pointer dereference after I2C communication errorStephan Gerhold
I2C communication errors (-EREMOTEIO) during the IRQ handler of nxp-nci result in a NULL pointer dereference at the moment: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oops: 0002 [#1] PREEMPT SMP NOPTI CPU: 1 PID: 355 Comm: irq/137-nxp-nci Not tainted 5.4.0-rc6 #1 RIP: 0010:skb_queue_tail+0x25/0x50 Call Trace: nci_recv_frame+0x36/0x90 [nci] nxp_nci_i2c_irq_thread_fn+0xd1/0x285 [nxp_nci_i2c] ? preempt_count_add+0x68/0xa0 ? irq_forced_thread_fn+0x80/0x80 irq_thread_fn+0x20/0x60 irq_thread+0xee/0x180 ? wake_threads_waitq+0x30/0x30 kthread+0xfb/0x130 ? irq_thread_check_affinity+0xd0/0xd0 ? kthread_park+0x90/0x90 ret_from_fork+0x1f/0x40 Afterward the kernel must be rebooted to work properly again. This happens because it attempts to call nci_recv_frame() with skb == NULL. However, unlike nxp_nci_fw_recv_frame(), nci_recv_frame() does not have any NULL checks for skb, causing the NULL pointer dereference. Change the code to call only nxp_nci_fw_recv_frame() in case of an error. Make sure to log it so it is obvious that a communication error occurred. The error above then becomes: nxp-nci_i2c i2c-NXP1001:00: NFC: Read failed with error -121 nci: __nci_request: wait_for_completion_interruptible_timeout failed 0 nxp-nci_i2c i2c-NXP1001:00: NFC: Read failed with error -121 Fixes: 6be88670fc59 ("NFC: nxp-nci_i2c: Add I2C support to NXP NCI driver") Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: David S.

2019-10-29nfc: pn533: Add autopoll capabilityLars Poeschel
pn532 devices support an autopoll command, that lets the chip automatically poll for selected nfc technologies instead of manually looping through every single nfc technology the user is interested in. This is faster and less cpu and bus intensive than manually polling. This adds this autopoll capability to the pn533 driver.

2019-10-29nfc: pn533: Split pn533 init & nfc_registerLars Poeschel
There is a problem in the initialisation and setup of the pn533: It registers with nfc too early. It could happen, that it finished registering with nfc and someone starts using it. But setup of the pn533 is not yet finished. Bad or at least unintended things could happen. So I split out nfc registering (and unregistering) to seperate functions that have to be called late in probe then. i2c requires a bit more love: i2c requests an irq in it's probe function. 'Commit 32ecc75ded72 ("NFC: pn533: change order operations in dev registation")' shows, this can not happen too early. An irq can be served before structs are fully initialized. The way chosen to prevent this is to request the irq after nfc_alloc_device initialized the structs, but before nfc_register_device. So there is now this pn532_i2c_nfc_alloc function.

2019-10-29nfc: pn533: Add dev_up/dev_down hooks to phy_opsLars Poeschel
This adds hooks for dev_up and dev_down to the phy_ops. They are optional. The idea is to inform the phy driver when the nfc chip is really going to be used. When it is not used, the phy driver can suspend it's interface to the nfc chip to save some power. The nfc chip is considered not in use before dev_up and after dev_down.

Fix two reset-gpio sanity checks which were never converted to use gpio_is_valid(), and make sure to use -EINVAL to indicate a missing reset line also for the UART-driver module parameter and for the USB driver. This specifically prevents the UART and USB drivers from incidentally trying to request and use gpio 0, and also avoids triggering a WARN() in gpio_to_desc() during probe when no valid reset line has been specified.

git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux Pull Wimplicit-fallthrough updates from Gustavo A. R. Silva: "Mark switch cases where we are expecting to fall through. This is part of the ongoing efforts to enable -Wimplicit-fallthrough. Most of them have been baking in linux-next for a whole development cycle. And with Stephen Rothwell's help, we've had linux-next nag-emails going out for newly introduced code that triggers -Wimplicit-fallthrough to avoid gaining more of these cases while we work to remove the ones that are already present. We are getting close to completing this work. Currently, there are only 32 of 2311 of these cases left to be addressed in linux-next. I'm auditing every case; I take a look into the code and analyze it in order to determine if I'm dealing with an actual bug or a false positive, as explained here: https://lore.kernel.org/lkml/c2fad584-1705-a5f2-d63c-824e9b96cf50@embeddedor.com/ While working on this, I've found and fixed the several missing break/return bugs, some of them introduced more than 5 years ago. Once this work is finished, we'll be able to universally enable "-Wimplicit-fallthrough" to avoid any of these kinds of bugs from entering the kernel again" * tag 'Wimplicit-fallthrough-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux: (27 commits) memstick: mark expected switch fall-throughs drm/nouveau/nvkm: mark expected switch fall-throughs NFC: st21nfca: Fix fall-through warnings NFC: pn533: mark expected switch fall-throughs block: Mark expected switch fall-throughs ASN.1: mark expected switch fall-through lib/cmdline.c: mark expected switch fall-throughs lib: zstd: Mark expected switch fall-throughs scsi: sym53c8xx_2: sym_nvram: Mark expected switch fall-through scsi: sym53c8xx_2: sym_hipd: mark expected switch fall-throughs scsi: ppa: mark expected switch fall-through scsi: osst: mark expected switch fall-throughs scsi: lpfc: lpfc_scsi: Mark expected switch fall-throughs scsi: lpfc: lpfc_nvme: Mark expected switch fall-through scsi: lpfc: lpfc_nportdisc: Mark expected switch fall-through scsi: lpfc: lpfc_hbadisc: Mark expected switch fall-throughs scsi: lpfc: lpfc_els: Mark expected switch fall-throughs scsi: lpfc: lpfc_ct: Mark expected switch fall-throughs scsi: imm: mark expected switch fall-throughs scsi: csiostor: csio_wr: mark expected switch fall-through ...
