2020-02-27NFC: Replace zero-length array with flexible-array memberGustavo A. R. Silva2-3/+3
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-02-19nfc: pn544: Fix occasional HW initialization failureDmitry Osipenko1-0/+1
The PN544 driver checks the "enable" polarity during of driver's probe and it's doing that by turning ON and OFF NFC with different polarities until enabling succeeds. It takes some time for the hardware to power-down, and thus, to deassert the IRQ that is raised by turning ON the hardware. Since the delay after last power-down of the polarity-checking process is missed in the code, the interrupt may trigger immediately after installing the IRQ handler (right after the checking is done), which results in IRQ handler trying to touch the disabled HW and ends with marking NFC as 'DEAD' during of the driver's probe: pn544_hci_i2c 1-002a: NFC: nfc_en polarity : active high pn544_hci_i2c 1-002a: NFC: invalid len byte shdlc: llc_shdlc_recv_frame: NULL Frame -> link is dead This patch fixes the occasional NFC initialization failure on Nexus 7 device.

The driver was doing a synchronous uninterruptible bulk-transfer without using a timeout. This could lead to the driver hanging on probe due to a malfunctioning (or malicious) device until the device is physically disconnected. While sleeping in probe the driver prevents other devices connected to the same hub from being added to (or removed from) the bus. An arbitrary limit of five seconds should be more than enough.

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.

2019-10-29nfc: pn533: Split pn533 init & nfc_registerLars Poeschel4-52/+80
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.

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.

2019-08-05NFC: nfcmrvl: fix gpio-handling regressionJohan Hovold3-4/+5
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.

2019-07-29NFC: nxp-nci: Clarify on supported chipsSedat Dilek1-2/+2
This patch clarifies on the supported NXP NCI chips and families and lists PN547 and PN548 separately which are known as NPC100 respectively NPC300. This helps to find informations and identify drivers on vendor's support websites. For details see the discussion in [1] and [2].

2019-07-29NFC: nxp-nci: Remove 'default n' for the coreAndy Shevchenko1-1/+0
It seems contributors follow the style of Kconfig entries where explicit 'default n' is present. The default 'default' is 'n' already, thus, drop these lines from Kconfig to make it more clear.

2019-07-29NFC: nxp-nci: Remove unused macro pr_fmt()Andy Shevchenko1-2/+0
The macro had never been used. The driver uses mostly the nfc_err(), which, with other macros in the family, is backed by corresponding dev_err(). pr_fmt() is not used for dev_err() macro. Moreover, there is no need to print the module name which is part of the device instance name anyway.

2019-07-29NFC: nxp-nci: Drop comma in terminator linesAndy Shevchenko1-2/+2
There is no need to have a comma after terminator entry in the arrays of IDs. This may prevent the misguided addition behind the terminator without compiler notice. Drop the comma in terminator lines for good. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Tested-by: Sedat Dilek <sedat.dilek@gmail.com> Signed-off-by: David S.
