2014-09-05fix off-by-one in bounds check in fpathconfRich Felker1-1/+1
this error resulted in an out-of-bounds read, as opposed to a reported error, when calling the function with an argument one greater than the max valid index.
2013-09-15support configurable page size on mips, powerpc and microblazeSzabolcs Nagy1-5/+5
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.
