* Linux: Define MMAP_CALL_INTERNALFlorian Weimer2022-05-041-32/+0
| | | | | | | | | | | | Unlike MMAP_CALL, this avoids a TCB dependency for an errno update on failure. <mmap_internal.h> cannot be included as is on several architectures due to the definition of page_unit, so introduce a separate header file for the definition of MMAP_CALL and MMAP_CALL_INTERNAL, <mmap_call.h>.

* Consolidate Linux mmap implementation (BZ#21270)Adhemerval Zanella2017-04-121-0/+32
This patch consolidates all Linux mmap implementations on default sysdeps/unix/sysv/linux/mmap{64}.c one. To accomodate all required architecture specific requeriments a new internal header is created (mmap_internal.h) where each architecture add its specific code requirements. Currently only x86_64 (to define MMAP_PREPARE to add MAP_32BITS), s390 (which have a different kernel ABI for mmap), m68k (which have variable minimum page sizes), and MIPS n32 (which zero extend the offset to handle negative one correctly) redefine the new header. The patch also fixes BZ#21270 where default mmap64 on architectures which uses mmap2 silent truncates large offsets value (larger than 1 << (page shift + 8 * sizeof (off_t)) or 1<<44 on architectures with 4096 bytes page size). The new consolidate implementation returns EINVAL as allowed by POSIX. It also adds a tests for on current tst-mmap-offset one. I have run a full make check on x86_64, x86_64-32, i686, aarch64, armhf, powerpc, powerpc64le, sparc64, and sparcv9 without any regressions. I also ran some basic tests (tst-mmap-offset) on sh4, m68k, and on qemu simulated MIPS32 and MIPS64. [BZ #21270] * posix/tst-mmap-offset.c (do_prepare): New function.
