Summary

[none]

Details

In the Linux kernel, the following vulnerability has been resolved:

md/raid1: properly indicate failure when ending a failed write request

This patch addresses a data corruption bug in raid1 arrays using bitmaps. Without this fix, the bitmap bits for the failed I/O end up being cleared.

Since we are in the failure leg of raid1endwriterequest, the request either needs to be retried (R1BIOWriteError) or failed (R1BIO_Degraded).
