* core, client, server: Support auxiliary group idsShehjar Tikoo2009-12-031-0/+19
| | | | | | | | | | | | | | | | | | | Support for auxiliary group ids is needed for transmission of more than one group id right through the xlator tree so that posix can use these group ids to perform in-house permission tests. The in-house permission checks are needed so that we do not have to depend on non-POSIX calls like setfs[ug]id for changing the user for each fop. The setfs[ug]id are also limited since they do not allow setting multiple group id as required for operation with NFS, which sends us all the group ids for a process issuing file system requests.

* client-protocol: fix race-condition encountered while accessing fdctxRaghavendra G2009-09-221-47/+218
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - In protocol/client, fdctx is accessed by two sets of procedures, protocol_client_mark_fd_bad falls in one set whereas the other set consists of all fops which receive fd as an argument. The way these fdctxs are got is different in these two sets. While in the former set, fdctx is accessed through conf->saved_fds, which is a list of fdctxs of fds representing opened/created files. In the latter set, fdctxs are got directly from fd through fd_ctx_get(). Now there can be race conditions between two threads executing one procedure from these two sets. As an example let us consider following scenario: A flush operation is timed out and polling thread executing protocol_client_mark_fd_bad, fuse thread executing client_release. This can happen because, immediately a reply for flush is written to fuse, a release on the same fd can be sent to glusterfs and the polling thread still might be doing cleanup. Consider following set of events: 1. fuse thread does fd_ctx_get (fd). 2. polling thread gets the same fdctx but through conf->saved_fds. 3. Now both threads go ahead and does list_del (fdctx) and eventually free fdctx. In other situations the same set events might occur and the threads executing fops other than flush in the second set might be accessing a fdctx freed in protocol_client_mark_fd_bad.

* protocol/client: fixed registration of saved_fdsAnand Avati2009-08-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.
