Subject: [PATCH] SUNRPC: Fix NFS READs that start at non-page-aligned offsets
|
||||
|
||||
Anj Duvnjak reports that the Kodi.tv NFS client is not able to read
|
||||
video files from a v5.10.11 Linux NFS server.
|
||||
|
||||
The new sendpage-based TCP sendto logic was not attentive to non-
|
||||
zero page_base values. nfsd_splice_read() sets that field when a
|
||||
READ payload starts in the middle of a page.
|
||||
|
||||
The Linux NFS client rarely emits an NFS READ that is not page-
|
||||
aligned. All of my testing so far has been with Linux clients, so I
|
||||
missed this one.
