* protocol/client: Prevent excessive logging of client's "disconnect" messages.Venkatesh Somyajulu2013-05-283-3/+18
| | | | | | | | | | | | | | | | | | | | | Problem: Currently when gluster volume start force is executed, client process will talk to glusterd to get the port of the brick. But if brick's path is not available it cannot return brick's port. So client process will keep connecting and disconnecting from glusterd for port-query which is ultimately responsible for execssive logging of disconnect messages. Fix: Message will be logged just once at INFO level after the first disconnect from glusterd. Afterwards "disconnect" messages will be logged in DEBUG mode.

* protocol/client: Periodically attempt reopensPranith Kumar K2013-02-035-93/+263
| | | | | | | | | | | | | | | | | | | | | | If the brick is taken down and the hard disk is replaced and the brick is brought back up, the re-opens of the open-fds will fail because the file is not present on the brick. Re-opens are not attempted even if the files are re-created by self-heal until the brick is brought down after the files are re-created and brought back up. This is a problem with a VM-store in a replica-setup. Until the fd is re-opened the writes will never happen on the brick where the hard-disk is replaced. To handle this situation gracefully, client xlator is enhanced to perform finodelk, fxattrop, writev, readv using anonymous fds if the file is yet to be re-opened. If the fop succeeds then client xlator attempts re-open.

* protocol/server: Do not access key after GF_FREE in _delete_auth_opt()Krutika Dhananjay2012-12-191-11/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEMS: 1.'key' becomes a dangling pointer after the first call to dict_del() returns, in _delete_auth_opt(). Therefore, the second call to fnmatch() is made with 'key' pointing to deallocated space. 2. Also, the name _delete_auth_opt seems to suggest that the function is intended to match and delete "auth" options from the dictionary. But it winds up deleting all the options irrespective of whether the pattern match was successful or not. The same is true with _copy_auth_opt(). FIX: Changed _delete_auth_opt() to delete the key ONLY if it matches either of the two patterns (auth.addr.*.allow and auth.addr.*.reject). Similarly, changed _copy_auth_opt() along the same lines.

* protocol/client: Fix negative return in client_setvolumeKrutika Dhananjay2012-08-011-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: The function dict_serialized_length could, owing to an error, return a negative integer (-EINVAL) that gets assigned to an unsigned int member 'dict_len' of gf_setvolume_req structure. FIX: Hold the value returned by dict_serialized_length in local variable ret (which is a signed int). Test if ret is negative, in which case the control would anyway branch to the label fail where the function returns. Otherwise dict_len is assigned with ret, in turn giving a more meaningful value to the attribute length. TEST: Attached gdb to glusterfs mount process, set breakpoint at client_setvolume, forced dict_serialized_length to return -EINVAL (indirectly by forcing _dict_serialized_length to return -EINVAL after setting count to -1 within its body) and checked the value of ret (which is now sure to contain a negative value) whose value will be appropriately tested to decide the next course of action within client_setvolume: whether to simply exit due to an error or execute the subsequent statements.

* protocol/client: Re-open should not have O_CREAT|O_TRUNC|O_EXCLPranith Kumar K2012-06-193-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA The bug is observed in 3.2.x because posix xlator changes the uid/gid of file as per frame->root-uid/gid if O_CREAT flag is set in open fop. Posix does not do this in 3.3.x so that bug does not appear anymore but this issue exposed the actual bug in client xlator re-open. Re-open of a file on re-connection should not perform re-open with the same flags at the time of open/create/opendir. Imagine a case where a file is opened with O_TRUNC|O_RDWR and some data is written to it, now if the brick goes down and comes back the file will be truncated. When I tested this case, the file is not truncated because locks xlator resets O_TRUNC unconditionally. Client xlator re-open bug and locks xlator bug cancel each other. Fix Reset O_CREAT|O_TRUNC|O_EXCL flags in re-open. Locks xlator should not reset O_TRUNC. Additional changes Removed wbflags as it is not assigned at all.
