* Use send() in client library to avoid SIGPIPESimo Sorce2013-04-031-2/+2
| | | | | | | | | | | The client library lives in applications that may not be blocking or ignoring SIGPIPE. Using write() can cause SIGPIPE to be raised in the application if the proxy is restarted. If the application does not catch the signal then it is terminated. Make sure this does not happen by using send() with the MSG_NOSIGNAL flag. Signed-off-by: Simo Sorce <simo@redhat.com>

* Fix infinite loop due to bad sign of variableSimo Sorce2013-04-031-1/+1
| | | | | | | | | | | Change the i variable to be a signed integer ot the loop will never end because and unsigned integer decremented past 0 simply wraps to a very big integer. The condition that would break the loop can never be true therefore the code would loop forever until eventually a double free would cause a crash. Found by Coverity.

| | | | | | | By setting closewait to 0 after waitpid we would loop forever not the max 10 times we intended to. Signed-off-by: Simo Sorce <simo@redhat.com>

* Add client side support to set allowed enctypesSimo Sorce2013-03-271-1/+92
| | | | | | | | | When using remote credentials, intercept set_cred_option calls and register an option into the existing set of crdentials with the request to set allowed entypes at the first use of said crdentials.

* Add extension to set allowable enctypesSimo Sorce2013-03-271-0/+39
| | | | | | | | | | | | | | | The krb5 mechanism has a non standard extention to allow setting a list of allowed enctypes to use with a particular set of crdentials. This patch adds an extension, registerd by a client as a gssx_cred's option, so that at the first use of this crdentials the proxy can try to set the requsted options. For now failure to set the option is only logged in debug mode and the operation to import credentials does not fail if the allowed enctypes cannot be set.

* Add helper function to check for krb5 oidSimo Sorce2013-03-272-0/+15
| | | | | | | | | | The krb5 mechanism supports multiple oids for historical reasons. Add a function to generically check if a mech oid is any of the krb5 mechanism known oids for functions that do not care which exact oid is being used of the krb5 family.

* Use token wrapper in gpp_remote_lo_local_ctxSimo Sorce2013-03-221-4/+39
| | | | | We need to do the wrapping in order to get back an actual local context. Otherwise we get back an interposed context from gssapi.

* Make socket path a configure optionSimo Sorce2013-03-225-39/+25
| | | | | | | The kernel uses the fixed path named /var/run/gssproxy.sock Make this default a configure time option and default to it. Also remove the option to change the socket at configure time, neither the kernel nor proxymech.so can cope with a change anyway.
* Enable kernel support.Simo Sorce2013-03-225-0/+61
| | | | | | | | The Linux kernel now requires the gss-proxy to signal when it is available. This is done by writing 1 to the file /proc/net/rpc/use-gss-proxy Once this happens the kernel will try to attach to the gss-proxy socket and use it instead of the classic rpc.svcgssd daemon.

* Use gssrpc instead of system rpcSimo Sorce2013-03-144-5/+10
