2011-11-08NFSD: Added fault injectionBryan Schumaker
Fault injection on the NFS server makes it easier to test the client's state manager and recovery threads. Simulating errors on the server is easier than finding the right conditions that cause them naturally. This patch uses debugfs to add a simple framework for fault injection to the server. This framework is a config option, and can be enabled through CONFIG_NFSD_FAULT_INJECTION. Assuming you have debugfs mounted to /sys/debug, a set of files will be created in /sys/debug/nfsd/. Writing to any of these files will cause the corresponding action and write a log entry to dmesg. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: J.

2011-07-15nfsd: Remove deprecated nfsctl system call and related code.NeilBrown
As promised in feature-removal-schedule.txt it is time to remove the nfsctl system call. Userspace has perferred to not use this call throughout 2.6 and it has been excluded in the default configuration since 2.6.36 (9 months ago). So this patch removes all the code that was being compiled out. There are still references to sys_nfsctl in various arch systemcall tables and related code. These should be cleaned out too, probably in the next merge window. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2010-10-27lockd: push lock_flocks downArnd Bergmann
lockd should use lock_flocks() instead of lock_kernel() to lock against posix locks accessing the i_flock list. This is a prerequisite to turning lock_flocks into a spinlock. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: J. Bruce Fields <bfields@redhat.com>

2010-10-21BKL: introduce CONFIG_BKL.Arnd Bergmann
With all the patches we have queued in the BKL removal tree, only a few dozen modules are left that actually rely on the BKL, and even there are lots of low-hanging fruit. We need to decide what to do about them, this patch illustrates one of the options: Every user of the BKL is marked as 'depends on BKL' in Kconfig, and the CONFIG_BKL becomes a user-visible option. If it gets disabled, no BKL using module can be built any more and the BKL code itself is compiled out. The one exception is file locking, which is practically always enabled and does a 'select BKL' instead. This effectively forces CONFIG_BKL to be enabled until we have solved the fs/lockd mess and can apply the patch that removes the BKL from fs/locks.c. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2010-09-22nfsd: allow deprecated interface to be compiled out.NeilBrown
Add CONFIG_NFSD_DEPRECATED, default to y. Only include deprecated interface if this is defined. This allows distros to remove this interface before the official removal, and allows developers to test without it. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J.

2010-09-12SUNRPC: Fix the NFSv4 and RPCSEC_GSS Kconfig dependenciesTrond Myklebust
The NFSv4 client's callback server calls svc_gss_principal(), which is defined in the auth_rpcgss.ko The NFSv4 server has the same dependency, and in addition calls svcauth_gss_flavor(), gss_mech_get_by_pseudoflavor(), gss_pseudoflavor_to_service() and gss_mech_put() from the same module. The module auth_rpcgss itself has no dependencies aside from sunrpc, so we only need to select RPCSEC_GSS.
