Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 2005-04-16 15:20:36 -07:00





lockd: Introduce new-style XDR functions for NLMv3 We'd like to prevent local buffer overflows caused by malicious or broken servers. New xdr_stream style decoders can do that. For efficiency, we also eventually want to be able to pass xdr_streams from call_encode() and call_decode() to all XDR encoding functions, rather than building an xdr_stream in every XDR encoding and decoding function in the kernel. To do all of this, rewrite the XDR encoding and decoding functions in fs/lockd/xdr.c to use xdr_streams. This makes them more or less incompatible with server-side XDR helper functions, so break them out into a separate source file. Static helper functions are left without the "inline" directive. This allows the compiler to choose automatically how to optimize these for size or speed. SHARE-related functionality doesn't seem to be used, as those functions are hiding behind a #define that isn't set anywhere that I can find. And, they've been in there forever (at least as far back as the kernel's git history goes), yet remain unused. Let's take the opportunity to bin them. It should be easy enough for someone to introduce proper XDR functions if at some point SHARE-related NLM functionality is desired. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Tested-by: J.

lockd: move lockd's grace period handling into its own module Currently, all of the grace period handling is part of lockd. Eventually though we'd like to be able to build v4-only servers, at which point we'll need to put all of this elsewhere. Move the code itself into fs/nfs_common and have it build a grace.ko module. Then, rejigger the Kconfig options so that both nfsd and lockd enable it automatically. Signed-off-by: Jeff Layton <jlayton@primarydata.com> 2014-09-12 16:40:20 -04:00

lockd: add a /proc/fs/lockd/nlm_end_grace file Add a new procfile that will allow a (privileged) userland process to end the NLM grace period early. The basic idea here will be to have sm-notify write to this file, if it sent out no NOTIFY requests when it runs. In that situation, we can generally expect that there will be no reclaim requests so the grace period can be lifted early.
