Change in ...nfs-ganesha[next]: Respect config parameters for mount path and server.

by Solomon Boulos (GerritHub)

Solomon Boulos has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/487452 ) Change subject: Respect config parameters for mount path and server. ...................................................................... Respect config parameters for mount path and server. With this change, the proxy can now correctly be pointed at whatever server (including IPv6 in theory) and mount point you want. The main cleanups are in the socket parsing and creation code. No more kFilestoreHost! When pointed at my old filestore instance: $ sudo mount -vvv -t nfs -o proto=tcp,vers=3 192.168.1.2:/testy ${HOME}/proxy-mount $ ls proxy-mount/ lost+found proxyv3_ganesha.conf and now a different (expected) outcome by proxying the more built up knfsd: $ sudo mount -vvv -t nfs -o proto=tcp,vers=3 192.168.1.2:/testy ${HOME}/proxy-mount $ ls proxy-mount/ bytes-again.txt bytes-small.txt copied.txt new.txt subdir yo.txt bytes-copy.txt bytes.txt hello.txt nope.txt woohoo.txt Change-Id: I952554a190dbc82eb2d45b9b013086ed4843e60e Signed-off-by: Solomon Boulos <boulos(a)google.com> --- M src/FSAL/FSAL_PROXY_V3/main.c M src/FSAL/FSAL_PROXY_V3/proxyv3_fsal_methods.h M src/FSAL/FSAL_PROXY_V3/rpc.c 3 files changed, 165 insertions(+), 45 deletions(-) git pull ssh://review.gerrithub.io:29418/ffilz/nfs-ganesha refs/changes/52/487452/1 -- To view, visit https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/487452 To unsubscribe, or for help writing mail filters, visit https://review.gerrithub.io/settings Gerrit-Project: ffilz/nfs-ganesha Gerrit-Branch: next Gerrit-Change-Id: I952554a190dbc82eb2d45b9b013086ed4843e60e Gerrit-Change-Number: 487452 Gerrit-PatchSet: 1 Gerrit-Owner: Solomon Boulos <boulos(a)google.com> Gerrit-MessageType: newchange

Change in ...nfs-ganesha[next]: Implement commit and respect maxwrite/maxread.

by Solomon Boulos (GerritHub)

Solomon Boulos has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/487451 ) Change subject: Implement commit and respect maxwrite/maxread. ...................................................................... Implement commit and respect maxwrite/maxread. With COMMIT implemented, dd runs successfully: $ dd if=proxy-mount/bytes.txt of=proxy-mount/bytes-again.txt 7000+0 records in 7000+0 records out 3584000 bytes (3.6 MB, 3.4 MiB) copied, 0.748621 s, 4.8 MB/s but, I had to actually teach my FSAL to listen to the server about its capabilities via FSINFO. Turns out linux's knfsd seems to default to 512KB as maxread/maxwrite and will rudely close the socket rather than just doing a short write.

Change in ...nfs-ganesha[next]: Implement read!

by Solomon Boulos (GerritHub)

Solomon Boulos has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/487448 ) Change subject: Implement read! ...................................................................... Implement read! On the server: $ dd if=/dev/urandom of=bytes.txt bs=512KB count=7 $ sha1sum bytes.txt 74cef82f324de11f714be420749b4eca8d46d1e9 bytes.txt and the client: $ sha1sum proxy-mount/bytes.txt 74cef82f324de11f714be420749b4eca8d46d1e9 proxy-mount/bytes.txt Found a couple things along the way: - First, nobody seems to implement hildebrand@'s READPLUS. - Second, Ganesha's "iovec"/readv() support seems inane. There's only a single offset, unlike readv(), so I don't see the point. Ganesha's NFSD won't ever generate a >1 length iovec either to the FSAL layer (seemingly), which is probably why the v4 Proxy FSAL just ignores this (but doesn't check). - Finally, my hardcoded 4KB buffer in rpc.c didn't cut it when attempting to read a bigger file. I still don't understand how you're supposed to allow xdrmem_create or whatever to do the right thing for you / allocate.

Change in ...nfs-ganesha[next]: Add aggressive debugging for FSAL handle functions.

by Solomon Boulos (GerritHub)

Solomon Boulos has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/487446 ) Change subject: Add aggressive debugging for FSAL handle functions. ...................................................................... Add aggressive debugging for FSAL handle functions. I believe I was incorrectly handing out some garbage during one of the handle_to_wire / wire_to_host variants, perhaps as a result of the lookup function special case for "." and "..". It's unclear what we *should* be returning (the FSAL API isn't clear about lifetimes or ownership), but once I cleaned up the NFS client state (via umount -f) these didn't recur. Either way, no reason to be silent in the future.

Change in ...nfs-ganesha[next]: Refactor GETATTR3 code for reuse by FSAL handlers.

Change in ...nfs-ganesha[next]: Implement just enough for MOUNT and stat!
