[PATCH v1 1/1] test_firmware: return ENOMEM instead of ENOSPC on failed memory allocation

by Mirsad Todorovac

[ Upstream commit 7dae593cd226a0bca61201cf85ceb9335cf63682 ] In a couple of situations like name = kstrndup(buf, count, GFP_KERNEL); if (!name) return -ENOSPC; the error is not actually "No space left on device", but "Out of memory". It is semantically correct to return -ENOMEM in all failed kstrndup() and kzalloc() cases in this driver, as it is not a problem with disk space, but with kernel memory allocator failing allocation.

[PATCH] dmaengine: pl330: Return DMA_PAUSED when transaction is paused

by Ilpo Järvinen

pl330_pause() does not set anything to indicate paused condition which causes pl330_tx_status() to return DMA_IN_PROGRESS. This breaks 8250 DMA flush after the fix in commit 57e9af7831dc ("serial: 8250_dma: Fix DMA Rx rearm race"). The function comment for pl330_pause() claims pause is supported but resume is not which is enough for 8250 DMA flush to work as long as DMA status reports DMA_PAUSED when appropriate. Add PAUSED state for descriptor and mark BUSY descriptors with PAUSED in pl330_pause(). Return DMA_PAUSED from pl330_tx_status() when the descriptor is PAUSED.

[PATCH] fs/proc/kcore: reinstate bounce buffer for KCORE_TEXT regions

by Lorenzo Stoakes

Some architectures do not populate the entire range categorised by KCORE_TEXT, so we must ensure that the kernel address we read from is valid. Unfortunately there is no solution currently available to do so with a purely iterator solution so reinstate the bounce buffer in this instance so we can use copy_from_kernel_nofault() in order to avoid page faults when regions are unmapped. This change partly reverts commit 2e1c0170771e ("fs/proc/kcore: avoid bounce buffer for ktext data"), reinstating the bounce buffer, but adapts the code to continue to use an iterator.

[PATCH v1 1/1] test_firmware: fix a memory leak with reqs buffer

by Mirsad Todorovac

[ commit be37bed754ed90b2655382f93f9724b3c1aae847 upstream ] Dan Carpenter spotted that test_fw_config->reqs will be leaked if trigger_batched_requests_store() is called two or more times. The same appears with trigger_batched_requests_async_store(). This bug wasn't triggered by the tests, but observed by Dan's visual inspection of the code. The recommended workaround was to return -EBUSY if test_fw_config->reqs is already allocated.

However, for use cases that have a special reaper thread that does nothing but wait on events on the ring, this causes a cosmetic issue where we know have one core marked as being "busy" with 100% iowait. While this isn't a grave issue, it is confusing to users. Rather than always mark us as being in iowait, gate setting of current->in_iowait to 1 by whether or not the waiting task has pending requests.
