2020-03-04MIPS: OCTEON: irq: Fix potential NULL pointer dereferenceGustavo A. R. Silva1-0/+3
There is a potential NULL pointer dereference in case kzalloc() fails and returns NULL. Fix this by adding a NULL check on *cd* This bug was detected with the help of Coccinelle.

2020-02-28MIPS: reduce print level for cache informationOleksij Rempel4-23/+23
Default printk log level is KERN_WARNING. This makes automatic log parsing problematic, since we get false positive alarms on not critical information. Set all not critical cache related information to KERN_INFO, the same level as used on most kernel drivers.

2020-02-19mips/jazz: Update jazz_defconfig for MIPS MagnumFinn Thain1-1/+12
Enable some options for machine type, framebuffer, serial controller and ATA interfaces. This allows a jazz_defconfig build to work on the emulated MIPS Magnum machine provided by qemu-system-mips64el.

2020-02-19mips/jazz: Remove redundant settings and shrink jazz_defconfigFinn Thain1-254/+0
Remove some redundant assignments, that have no effect on 'make jazz_defconfig': CONFIG_INET_XFRM_MODE_TRANSPORT=m CONFIG_INET_XFRM_MODE_TUNNEL=m CONFIG_CRYPTO_HMAC=y Also drop the settings relating to crypto, wireless, advanced networking etc. The Kconfig defaults for these options are fine. This reduces the size of vmlinux so it can be launched by "NetBSD/arc Bootstrap, Revision 1.1", which is conveniently available on NetBSD/arc 5.1 ISO images.

2020-02-19MIPS: configs: Cleanup old Kconfig optionsKrzysztof Kozlowski16-23/+4
CONFIG_MTD_NAND_IDS is gone and not needed (part of CONFIG_MTD_NAND) since commit f16bd7ca0457 ("mtd: nand: Kill the MTD_NAND_IDS Kconfig option"). CONFIG_IOSCHED_DEADLINE, CONFIG_IOSCHED_CFQ and CONFIG_DEFAULT_NOOP are gone since commit f382fb0bcef4 ("block: remove legacy IO schedulers"). The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be now enabled by default (along with MQ_IOSCHED_KYBER). The BFQ_GROUP_IOSCHED is the only multiqueue scheduler which comes with group scheduling so select it in configs previously choosing CFQ_GROUP_IOSCHED.

2020-02-14Input: cyapa - replace zero-length array with flexible-array memberGustavo A. R. Silva1-4/+4
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.

Many users have reported nvme triggered irq_startup() warnings during shutdown. The driver uses the nvme queue's irq to synchronize scanning for completions, and enabling an interrupt affined to only offline CPUs triggers the alarming warning. Move the final CQE check to after disabling the device and all registered interrupts have been torn down so that we do not have any IRQ to synchronize.

2020-02-14nvme: prevent warning triggered by nvme_stop_keep_aliveNigel Kirkland3-7/+7
Delayed keep alive work is queued on system workqueue and may be cancelled via nvme_stop_keep_alive from nvme_reset_wq, nvme_fc_wq or nvme_wq. Check_flush_dependency detects mismatched attributes between the work-queue context used to cancel the keep alive work and system-wq. Specifically system-wq does not have the WQ_MEM_RECLAIM flag, whereas the contexts used to cancel keep alive work have WQ_MEM_RECLAIM flag. Example warning: workqueue: WQ_MEM_RECLAIM nvme-reset-wq:nvme_fc_reset_ctrl_work [nvme_fc] is flushing !WQ_MEM_RECLAIM events:nvme_keep_alive_work [nvme_core] To avoid the flags mismatch, delayed keep alive work is queued on nvme_wq. However this creates a secondary concern where work and a request to cancel that work may be in the same work queue - namely err_work in the rdma and tcp transports, which will want to flush/cancel the keep alive work which will now be on nvme_wq. After reviewing the transports, it looks like err_work can be moved to nvme_reset_wq. In fact that aligns them better with transition into RESETTING and performing related reset work in nvme_reset_wq. Change nvme-rdma and nvme-tcp to perform err_work in nvme_reset_wq.

When nvme_tcp_io_work() fails to send to socket due to connection close/reset, error_recovery work is triggered from nvme_tcp_state_change() socket callback. This cancels all the active requests in the tagset, which requeues them. The failed request, however, was ended and thus requeued individually as well unless send returned -EPIPE. Another return code to be treated the same way is -ECONNRESET.
