NFSD: Remove CONFIG_NFSD_V3

2022-03-11T15:25:14Z

Eventually support for NFSv2 in the Linux NFS server is to be deprecated and then removed. However, NFSv2 is the "always supported" version that is available as soon as CONFIG_NFSD is set. Before NFSv2 support can be removed, we need to choose a different "always supported" version. This patch removes CONFIG_NFSD_V3 so that NFSv3 is always supported, as NFSv2 is today. When NFSv2 support is removed, NFSv3 will become the only "always supported" NFS version. The defconfigs still need to be updated to remove CONFIG_NFSD_V3=y. Signed-off-by: Chuck Lever

nfsd/blocklayout: use ->get_unique_id instead of sending SCSI commands

2021-10-22T14:33:57Z

Call the ->get_unique_id method to query the SCSI identifiers. This can use the cached VPD page in the sd driver instead of sending a command on every LAYOUTGET. It will also allow to support NVMe based volumes if the draft for that ever takes off. Signed-off-by: Christoph Hellwig Acked-by: J.

scsi: core: Rename CONFIG_BLK_SCSI_REQUEST to CONFIG_SCSI_COMMON

2021-07-29T02:24:27Z

CONFIG_BLK_SCSI_REQUEST is rather misnamed as it enables building a small amount of code shared by the SCSI initiator, target, and consumers of the scsi_request passthrough API. Rename it and also allow building it as a module.

NFSv4.2: Remove ifdef CONFIG_NFSD from NFSv4.2 client SSC code.

2021-04-26T13:29:17Z

The client SSC code should not depend on any of the CONFIG_NFSD config. This patch removes all CONFIG_NFSD from NFSv4.2 client SSC code and simplifies the config of CONFIG_NFS_V4_2_SSC_HELPER, NFSD_V4_2_INTER_SSC. Signed-off-by: Dai Ngo Signed-off-by: Trond Myklebust

fs: nfsd: fix kconfig dependency warning for NFSD_V4

2021-03-06T21:41:48Z

When NFSD_V4 is enabled and CRYPTO is disabled, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for CRYPTO_SHA256 Depends on [n]: CRYPTO [=n] Selected by [y]: - NFSD_V4 [=y] && NETWORK_FILESYSTEMS [=y] && NFSD [=y] && PROC_FS [=y] WARNING: unmet direct dependencies detected for CRYPTO_MD5 Depends on [n]: CRYPTO [=n] Selected by [y]: - NFSD_V4 [=y] && NETWORK_FILESYSTEMS [=y] && NFSD [=y] && PROC_FS [=y] This is because NFSD_V4 selects CRYPTO_MD5 and CRYPTO_SHA256, without depending on or selecting CRYPTO, despite those config options being subordinate to CRYPTO.

NFSv4_2: SSC helper should use its own config.

2021-01-28T15:55:37Z

Currently NFSv4_2 SSC helper, nfs_ssc, incorrectly uses GRACE_PERIOD as its config. Fix by adding new config NFS_V4_2_SSC_HELPER which depends on NFS_V4_2 and is automatically selected when NFSD_V4 is enabled. Also removed the file name from a comment in nfs_ssc.c.

NFSv4.2: Fix NFS4ERR_STALE error when doing inter server copy

2020-10-21T14:31:20Z

NFS_FS=y as dependency of CONFIG_NFSD_V4_2_INTER_SSC still have build errors and some configs with NFSD=m to get NFS4ERR_STALE error when doing inter server copy. Added ops table in nfs_common for knfsd to access NFS client modules. Fixes: 3ac3711adb88 ("NFSD: Fix NFS server build errors") Signed-off-by: Dai Ngo Signed-off-by: J. Bruce Fields

nfsd: remove fault injection code

2020-09-25T22:01:26Z

It was an interesting idea but nobody seems to be using it, it's buggy at this point, and nfs4state.c is already complicated enough without it. The new nfsd/clients/ code provides some of the same functionality, and could probably do more if desired. This feature has been deprecated since 9d60d93198c6 ("Deprecate nfsd fault injection").
