* features/access-control: skip access-tests if the call is from fusePranith K2011-01-261-0/+3
| | | | | | | | | | | | | | Fuse cant send aux gids. So access-control checks treat non-primary-group membership of user as "other". So skip access-control checks if the call is from fuse. We added a hack to treat all calls with pid set to 1 as calls from nfs. So for calls with pid not 1 we skip the access-control checks on all fops.

* core: Do internal latency measurement of FOPs.Vikas Gorur2010-04-041-2/+54
| | | | | | | | | | | | | | | | | | | This patch adds a facility by which each translator keeps track of the average latency of a FOP from its point of view. That is, the duration between the translator handing over the call to a lower-level translator and the reply coming back. The latency measurement is off by default, and can be toggled by sending SIGUSR2 to the GlusterFS process. Latency data is printed as part of the process state dump.

* core, client, server: Support auxiliary group idsShehjar Tikoo2009-12-031-0/+6
| | | | | | | | | | | | | | | | | | | 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.
