NFSv4.1/pNFS: Don't request a minimal read layout beyond the end of file · 2d89a1d3

由 Trond Myklebust 提交于 8月 31, 2015

If we have a read layout, then sanity check the minimal layout length
so that it does not extend beyond the end of file.

NFSv4.1/pnfs: Handle LAYOUTGET return values correctly · 21b874c8

由 Trond Myklebust 提交于 8月 31, 2015

According to RFC5661 section 18.43.3, if the server cannot satisfy
the loga_minlength argument to LAYOUTGET, there are 2 cases:
1) If loga_minlength == 0, it returns NFS4ERR_LAYOUTTRYLATER
2) If loga_minlength != 0, it returns NFS4ERR_BADLAYOUT

NFSv4.1: Fix a protocol issue with CLOSE stateids · 4a1e2feb

由 Trond Myklebust 提交于 8月 30, 2015

According to RFC5661 Section 18.2.4, CLOSE is supposed to return
the zero stateid. This means that nfs_clear_open_stateid_locked()
cannot assume that the result stateid will always match the 'other'
field of the existing open stateid when trying to determine a race
with a parallel OPEN.

Instead, we look at the argument, and check for matches.

NFSv4.1/flexfiles: Don't mark the entire deviceid as bad for file errors · 90816d1d

由 Trond Myklebust 提交于 8月 30, 2015

If the file was fenced and/or has been deleted on the DS, then we want
to retry pNFS after a layoutreturn with error report. If the server
cannot fix the problem, then we rely on it to tell us so in the
response to the LAYOUTGET.

NFSv4.1/flexfiles: Fix a protocol error in layoutreturn · d1354907

由 Trond Myklebust 提交于 8月 27, 2015

According to the flexfiles protocol, the layoutreturn should specify an
array of errors in the following format:

struct ff_ioerr4 {
	offset4        ffie_offset;
	length4        ffie_length;
	stateid4       ffie_stateid;
	device_error4  ffie_errors<>;
};

This patch fixes up the code to ensure that our ffie_errors is indeed
encoded as an array (albeit with only a single entry).
