* [LTP] Posix test case mmap/31-1 fails on Linux/eglibc @ 2011-12-28 10:55 Kang Kai 2011-12-28 18:16 ` Cyril Hrubis 2012-01-04 1:37 ` Yasuaki Ishimatsu 0 siblings, 2 replies; 7+ messages in thread From: Kang Kai @ 2011-12-28 10:55 UTC (permalink / raw) To: ltp-list Hi all, I run mmap/31-1 failed with ENOMEM on linux, with error message: off: fffffffffffff000, len: fffffffffffff000 Test FAIL: expect EOVERFLOW but get other error: Cannot allocate memory But compare to mmap/24-2, it mmap() the same length but pass. Its output: available memory: 18446744073709551615 addr: 7f78c54fa000, len: ffffffffffffffff addr: 7f78c54fa000, len: fffffffffffff000 Test Pass: mmap/24-2.c Get ENOMEM: Cannot allocate memory So I suppose that mmap/31-1 may need update, but I don't know how to make mmap() overflow as expect.

I would start with careful reading of the mmap() manpages/docs, as most likely some of the assumptions that the testcase makes is incorrect. -- Cyril Hrubis chrubis@suse.cz ------------------------------------------------------------------------------ Ridiculously easy VDI.

I don't think mmap/31-1 need update since it is Linux Kernel's problem, not the test's problem.
