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/legacy/getpagesize.c | 2 +- src/legacy/valloc.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'src/legacy') diff --git a/src/legacy/getpagesize.c b/src/legacy/getpagesize.c index 5ede652b..a47995cb 100644 --- a/src/legacy/getpagesize.c +++ b/src/legacy/getpagesize.c @@ -1,5 +1,5 @@ #include -#include +#include "libc.h" int getpagesize(void) { diff --git a/src/legacy/valloc.c b/src/legacy/valloc.c index e48cf214..5af2256a 100644 --- a/src/legacy/valloc.c +++ b/src/legacy/valloc.c @@ -1,6 +1,6 @@ #define _BSD_SOURCE #include -#include +#include "libc.h" void *valloc(size_t size) { -- cgit v1.2.1
