Revision ff7e0055bb5ddbbb320cdd8dfd3e18672bddd2ad authored by Andy Lutomirski on 15 August 2014, 18:43:37 UTC, committed by Rusty Russell on 15 August 2014, 19:17:00 UTC
The commit
4982223e51e8 module: set nx before marking module MODULE_STATE_COMING.
introduced a regression: if a module fails to parse its arguments or
if mod_sysfs_setup fails, then the module's memory will be freed
while still read-only. Anything that reuses that memory will crash
as soon as it tries to write to it.
