Section mismatches after applying GrSecurity patch

Postby johnspaul92 » Mon Jun 24, 2013 7:56 am

I patched linux kernel 3.2(using the stable patch for 3.2) and kernel 3.8(using the test version of the patch for 3.8) but in both the cases when i compiled the kernel there were over 5000 section mismatches (mostly caused by __init). In most of the places a function is declared as __init but the structure used inside the function doesn't have a __initdata in its definition (i think these might not cause any run time issue but if there are cases where the structure is _init and the funtion is not __init then it will cause a problem right??). So has anyone checked if any of these section mismatches create any problem during runtime??????

the extra section mismatches (on top of the vanilla linux count, that is) are due to PaX detecting writable function pointers as well, not related to __init. if you want to get back the original counts, just revert the hunks applied to scripts/mod/modpost.c.
