From b20760c02318fa6da228587c401a8b2bb22a1aab Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Sun, 15 Sep 2013 02:00:32 +0000 Subject: support configurable page size on mips, powerpc and microblaze PAGE_SIZE was hardcoded to 4096, which is historically what most systems use, but on several archs it is a kernel config parameter, user space can only know it at execution time from the aux vector. PAGE_SIZE and PAGESIZE are not defined on archs where page size is a runtime parameter, applications should use sysconf(_SC_PAGE_SIZE) to query it. Internally libc code defines PAGE_SIZE to libc.page_size, which is set to aux[AT_PAGESZ] in __init_libc and early in __dynlink as well. (Note that libc.page_size can be accessed without GOT, ie. before relocations are done) Some fpathconf settings are hardcoded to 4096, these should be actually queried from the filesystem using statfs. --- src/mman/mprotect.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/mman') diff --git a/src/mman/mprotect.c b/src/mman/mprotect.c index 5ab2d8b0..f488486d 100644 --- a/src/mman/mprotect.c +++ b/src/mman/mprotect.c @@ -1,5 +1,5 @@ #include -#include +#include "libc.h" #include "syscall.h" int mprotect(void *addr, size_t len, int prot) -- cgit v1.2.1
