glusterfs.git, branch v2.0.6 GlusterFS is a distributed file-system capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system.

protocol/client: fixed registration of saved_fds 2009-08-07T08:24:33+00:00 Anand Avati avati@dev.gluster.com 2009-08-06T21:51:33+00:00 2be295d30acd61a919796227fef71f2757f88440 In client_open_cbk, client_opendir_cbk the list_add_tail macros were invoked with wrong ordered arguments, causing the existing registered fd list to get unlinked from the saved_fds list. The effects of this is far fetched - when transport disconnects, open fds are no more marked bad as they are not reachable from the saved_fds list. After reconnection, resumed access on this fd causes reference to invalid fds on the server. It could appear in the form of 'unresolved fd' error, readdir happening on a file fd, files reading from other files, etc. Signed-off-by: Anand V.

in the previous commit, the path info was removed to prevent the
segfault, which instead could have been provided from request
header directly. More specific information is required for debugging,
and hence adding the path log.

The root cause of this error is not found yet. But this check will
make sure that there is no crash when the situation happens.
Segfault can happen when a readdir() call comes over file's fd.

With this option, 'single point of failure', in case of volfile server can be
avoided.

Noticed that in few cases, where ib-verbs doesn't handle a bigger
sized buffer to be sent across, which happens without problem in
tcp. Caused frame losses in the case where server's reply msg was
bigger, hence the msg got dropped at the server end. With this patch
ib-verbs buffer size is fixed to 512KB. (4 x page-size)
