2016-09-15modutils: support finit_module syscallMike Frysinger
On some systems like Chromium OS, loading modules from non-verified filesystems is denied. Only finit_module is allowed because an open fd is passed which can be checked against a verified location. Change the module loading code to first attempt finit_module and if that fails for whatever reason, fall back to the existing logic. On x86_64, this adds ~80 bytes to modutils/modutils.o and ~68 bytes to modutils/modprobe-small.o.

2015-02-12modprobe-small: if concurrent module load did not succeed, waitDenys Vlasenko
usecase: two sd cards are being mounted in parallel at same time on dual core. example modules which are getting loaded is nls_cp437. While one module is being loaded , it makes state in /proc/modules as 'coming' and then starts doing its module init function (in our case - registering nls). meanwhile on other core, if modprobe returns that is has already been loaded, then it will continue and search for the nls list which is not yet finished from first module init. This fails resulting in not mounting sd card. function old new delta process_module 667 746 +79 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
