9P: fix return value in v9fs_fid_xattr_set

2014-06-01T20:31:34+00:00

v9fs_fid_xattr_set is supposed to return 0 on success. This corrects the behaviour introduced in commit bdd5c28dcb8330b9074404cc92a0b83aae5606a "9p: fix return value in case in v9fs_fid_xattr_set()" (The function returns a negative error on error, as expected) Signed-off-by: Dominique Martinet Signed-off-by: Eric Van Hensbergen

9p: fix return value in case in v9fs_fid_xattr_set()

2013-11-23T22:10:31+00:00

In case of error in the p9_client_write, the function v9fs_fid_xattr_set should return its negative value, what was never being done. In case of success it only retuned 0. Now it returns the 'offset' variable (write_count total). Signed-off-by: Geyslan G. Bem Signed-off-by: Eric Van Hensbergen

fs/9p: xattr: add trusted and security namespaces

2013-07-08T03:02:18+00:00

Allow requests for security.* and trusted.* xattr name spaces to pass through to server. The new files are 99% cut and paste from fs/9p/xattr_user.c with the namespaces changed. It has the intended effect in superficial testing. I do not know much detail about how these namespaces are used, but passing them through to the server, which can decide whether to handle them or not, seems reasonable. I want to support a use case where an ext4 file system is mounted via 9P, then re-exported via samba to windows clients in a cluster. Windows wants to store xattrs such as security.NTACL. This works when ext4 directly backs samba, but not when 9P is inserted. This use case is documented here: http://code.google.com/p/diod/issues/detail?id=95 Signed-off-by: Jim Garlick Signed-off-by: Eric Van Hensbergen

9p: Reduce object size with CONFIG_NET_9P_DEBUG

2012-01-05T16:51:44+00:00

Reduce object size by deduplicating formats. Use vsprintf extension %pV. Rename P9_DPRINTK uses to p9_debug, align arguments. Add function for _p9_debug and macro to add __func__. Add missing "\n"s to p9_debug uses. Remove embedded function names as p9_debug adds it. Remove P9_EPRINTK macro and convert use to pr_. Add and use pr_fmt and pr_. $ size fs/9p/built-in.o* text data bss dec hex filename 62133 984 16000 79117 1350d fs/9p/built-in.o.new 67342 984 16928 85254 14d06 fs/9p/built-in.o.old $ size net/9p/built-in.o* text data bss dec hex filename 88792 4148 22024 114964 1c114 net/9p/built-in.o.new 94072 4148 23232 121452 1da6c net/9p/built-in.o.old Signed-off-by: Joe Perches Signed-off-by: Eric Van Hensbergen
