[libvirt] [php PATCH] Fix compiler warnings after int to long conversion
by Dawid Zamirski
The previous patch [1] caused compiler warnings after variable types
were changed from int to long and this patch fixes this.

[libvirt] [php PATCH] Use long variable type for zend_parse_parameters.
by Dawid Zamirski
This patch fixes a bug where zend_parse_parameters would segfault on
certain PHP version (spotted on PHP 5.3.2 64bit) where type specifier is
long "l" and variable reference is int or unsigned int. Changing the
variable type from int or unsigned int to long fixes the problem for me
and is a known issue [1]. This did not happen in newer PHP version
(5.3.10).

---------------------------------------------------------------------------------------------
Issue is not seen for other nic drivers when loaded , i.e verified with
be2net ,e1000e , igb drivers , so it looks like specific to ixgbe
driver module.
This problem can be addressed by increasing the size of the socket
receive buffer via nl_socket_set_buffer_size(). However, since reliable
transmissions from kernel to user are impossible in any case, I don't
know if we need to ensure enough buffer and how much it will be enough.
In my test, 32768*4 bytes of receive buffer size is ok. Below is my patch.

Given that it exists in everything from 4.2 onwards why do you need to
check for it?
