* Force O_CLOEXEC on the NETLINK socketv0.7David Sommerseth2011-04-121-0/+8
| | | | | | | | | | | To avoid that the NETLINK socket is available to forked children, set the FD_CLOEXEC flag on the NETLINK socket. This also avoids SELinux from complaining on Fedora 14. For more information: https://bugzilla.redhat.com/show_bug.cgi?id=689843 Signed-off-by: David Sommerseth <davids@redhat.com>
* Only open the NETLINK interface when neededDavid Sommerseth2011-04-115-72/+115
| | | | | | | | | Do not open a NETLINK connection when loading the module, but rahter open it when needed. In a case where multiple users needs the connection, it will be shared and only closed when the last active user is done. Signed-off-by: David Sommerseth <davids@redhat.com>
* Fixed several memory leaksDavid Sommerseth2011-04-113-10/+22
| | | | | | | | | | | Several places python-ethtool leaked memory, mostly due to missing Py_DECREF() calls on objects being put in to python lists (via PyList_Append() calls). This revealed an issue in addition where the IPv6 addresses pointers in some cases could freed more times. This is fixed as well. Signed-off-by: David Sommerseth <davids@redhat.com>
* Improved error situations in case of NULL returnsDavid Sommerseth2011-02-251-0/+23
| | | | | | | | _ethtool_etherinfo_get_ipv6_addresses() didn't check too well several Python calls if it would return NULL. Reported-by: Dave Malcolm <dmalcolm@redhat.com> Signed-off-by: David Sommerseth <davids@redhat.com>
* RETURN_STRING() did not use Py_INCREF() when returning Py_NoneDavid Sommerseth2011-02-251-1/+1
| | | | | | | | | | | | | | | From RH BZ#680269: #define RETURN_STRING(str) (str ? PyString_FromString(str) : Py_None) This isn't incrementing the reference count on the Py_None singleton when it should be (the caller assumes that it "owns" a ref on the result of _getter, and will decref it), it could cause the python process to bail out: "Fatal Python error: deallocating None" if run repeatedly.

* Avoid duplicating IPv6 address informationDavid Sommerseth2011-01-191-0/+8
| | | | | | | | | In commit c52ed2cbdc5b851ebc7bc19d7c682b14a4a16ba4 a free_ipv6addresses() call was removed, which lead to duplicated IPv6 address information in some cases. Re-add this freeing, to be sure we don't add existing information to an already existing pointer chain. Signed-off-by: David Sommerseth <davids@redhat.com>
* Added ethtool.version string constantDavid Sommerseth2011-01-191-0/+1
| | | | | | This is useful to identify the python-ethtool version at runtime. Signed-off-by: David Sommerseth <davids@redhat.com>
* Don't segfault if we don't receive any address from rtnl_link_get_addr()David Sommerseth2010-12-211-1/+1
| | | | | | | The callback function for device link information was lacking a simple check to avoid a SEGV in these situations. Signed-off-by: David Sommerseth <davids@redhat.com>
* Python reference counter was not properly set for etherinfo_ipv6addr objectsDavid Sommerseth2010-08-092-5/+4
| | | | | | | | | This caused a double free situation, when Python tried to free the object if the etherinfo::get_ipv6_addresses() method was called several times. In addition the ethtool::get_interfaces_info() would also free the structures uses by etherinfo_ipv6addr objects. Signed-off-by: David Sommerseth <davids@redhat.com>
* Get rid of not needed struct wrappingDavid Sommerseth2010-08-034-32/+25
| | | | | | | | | | The struct nl_handle was wrapped inside struct _nlconnection. This is really not needed if open_netlink() and close_netlink() functions uses "pointer's pointer" (struct nl_handle **) instead. Removes also the need to declare a static struct _nlconnection, as the global nlconnection variable can now be a pointer as well. Signed-off-by: David Sommerseth <davids@redhat.com>
* Don't append newline when etherinfo_ipv6addr objects are used as stringsDavid Sommerseth2010-08-031-1/+1

* Moved etherinfo::ipv6_addresses to etherinfo::get_ipv6_addresses()David Sommerseth2010-08-031-29/+46
| | | | | | | This is more appropriate as it is not a static list of IPv6 address objects which are returned. Signed-off-by: David Sommerseth <davids@redhat.com>

* Improved IPv6 supportDavid Sommerseth2010-07-306-38/+348
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As the IPv6 protocol allows a single device to have more than one IPv6 address, the previous implementation did not provide all IPv6 information. It would reject all except the last parsed IPv6 address. NOTE: This implementation will break the previous API. This change removes the ethtool.etherinfo.ipv6_address and ethtool.etherinfo.ipv6_netmask members. A new member is added, ethtool.etherinfo.ipv6_addresses (in plural). This contains a tupple list containing of ethtool.etherinfo_ipv6addr objects, one object for each configured IPv6 address on the device. These objects have the following members available: .address - The IPv6 address .netmask - The IPv6 netmask (in bit notation) .scope - A string with the IPv6 address scope Example code: import ethtool devs = ethtool.get_interfaces_info('eth0') for ip6 in devs[0].ipv6_addresses: print "[%s] %s/%i" % (ip6.scope, ip6.address, ip6.netmask) Signed-off-by: David Sommerseth <davids@redhat.com>

* Renamed get_interface_info() to get_interfaces_info() and updated help stringDavid Sommerseth2010-05-041-3/+5
| | | | | This is to make it a bit clearer that the result type of this function always will be a list of ethtool.etherinfo objects.

* Added parameter to get_interface_inf()David Sommerseth2009-09-161-2/+66
| | | | | | | | | | It can handle a string with a device name or a list or a tuple list with more devices. dev = ethtool.get_interface_info(['lo','eth0','pan0']) dev = ethtool.get_interface_info(('eth0','virbr0')) dev = ethtool.get_interface_info('lo') dev = ethtool.get_interface_info()

* Completed implementing the new Python get_interface_info() function.David Sommerseth2009-09-073-17/+124
| | | | | | | | | | | | | | | | | | It will return a list of Python etherinfo objects. These objects have the following properties: .device - Device name .mac_address - Hardware address .ipv4_address .ipv4_netmask .ipv4_broadcast .ipv6_address .ipv6_netmask In addition, it will produce a human readable output if these objects are treated as strings. It will not be possible to modify any of the properties in these objects.

This cset also introduces struct_desc_from_dict, that will help with other dict based python bindings, not just in python-ethtool. Please let me know if I'm reinventing the wheel, i.e. if there are other Python dict to C struct facilities out there (I bet there is, but heck, this one was easy enough to implement and doesn't requires external support to get this done 8)).
