* Fix select decoding with bogus (huge or negative) nfds.Dr. David Alan Gilbert2013-11-05
| | | | | | | | | | | | We used to allocate and fetch bit arrays using a sanitized length, but then iterate over them with "j < arg[0]" condition, where arg[0] is not sanitized. This segfaults if arg[0] is huge or negative. This change fixes this. Add test/select.c to capture the case.

* Improve sigreturn decoding on x86 to show RT signal bits too.Denys Vlasenko2013-07-16
| | | | | | | | | This includes decoding of 32-bit sigreturn by 64-bit strace, which previously wasn't done. Added a test for it. Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com>
* test: add mtd/ubi test helpersMike Frysinger2013-05-02
| | | | | | | | | | | | I used these to develop the mtd/ubi ioctl decoders. * test/.gitignore: Add mtd/ubi. * test/Makefile: Declare all tests in a PROGS var. Declare build targets .PHONY. (all): Depend on $(PROGS) instead of hardcoded list. (clean): Remove $(PROGS) instead of hardcoded list. * test/mtd.c: New file. * test/ubi.c: Likewise.
* test: include headers for used funcsMike Frysinger2013-05-02
| | | | | | | | | | | | | These funcs use things like wait/write/read/strcmp but sometimes don't include the right header for them. * test/Makefile: Add -Wall to CFLAGS. * test/clone.c: Include unistd.h. * test/fork.c: Include sys/wait.h. * test/sig.c: Include unistd.h. * test/sigkill_rain.c: Include sys/wait.h. * test/vfork.c: Include sys/wait.h. * test/wait_must_be_interruptible.c: Include string.h
* test/threaded_execve: fix on metagJames Hogan2013-05-01
| | | | | | | | | | The metag ABI has stacks growing upwards so clone expects the stack argument to point at the bottom of the stack instead of the top. * test/threaded_execve.c [__metag__]: Define clone2 differently to avoid a segfault at runtime.

* test/skodic: make a bit more portableJames Hogan2013-05-01
| | | | | | | | | * test/skodic.c (main): Don't use MAP_FIXED since valid virtual addresses vary between architectures (as far as I can tell the use of MAP_FIXED is not relevant to the test). Also don't assume the file desriptor returned by open call is 3 when passing it to mmap. Signed-off-by: James Hogan <james.hogan@imgtec.com>
* Clean up mmap decodingDenys Vlasenko2013-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous code merges too many similar, but different ways of decoding mmap. For example, sys_old_mmap is "params in memory" API... except SH[64], where it is "params in regs", i.e. what sys_mmap ("new mmap") function does on other arches! It's much simpler when every mmap handler has same API regardless of arch. Where API means whether params are in regs or in memory, and whether offset is in bytes, pages, or 4k blocks. Then we just insert correct function pointers into arch syscall tables. It turns out there are four common mmap APIs over all architectures which exist in Linux kernel, and one outlier for S390. A number of mmap decoders were plain wrong in arch tables. For example, BFIN has no old_mmap. It returns ENOSYS. I checked kernel sources for all arches nad fixed the tables. There was dead code for x86_64 for old_mmap: x86_64 has no old_mmap. * mem.c: Refactor mmap functions so that we have five mmap syscall handlers, each with the fixed API (not varying by arch). * pathtrace.c (pathtrace_match): Adjust sys_func == mmap_func checks. * linux/syscall.h: Declare new mmap syscall handler functions. * linux/arm/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/avr32/syscallent.h: mmap is sys_mmap_pgoff. * linux/bfin/syscallent.h: old_mmap is ENOSYS, mmap2 is sys_mmap_pgoff. * linux/hppa/syscallent.h: mmap2 is sys_mmap_4koff. * linux/i386/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/ia64/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/m68k/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/microblaze/syscallent.h: old_mmap is sys_mmap, mmap2 is sys_mmap_pgoff. * linux/mips/syscallent.h: mmap is sys_mmap_4kgoff. * linux/or1k/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/powerpc/syscallent.h: mmap2 is sys_mmap_4kgoff. * linux/s390/syscallent.h: mmap2 is sys_old_mmap_pgoff. * linux/s390x/syscallent.h: mmap is sys_old_mmap and thus has 1 arg. * linux/sh/syscallent.h: old_mmap2 is sys_mmap, mmap2 is sys_mmap_4koff. * linux/sh64/syscallent.h: Likewise. * linux/sparc/syscallent1.h: mmap is TD|TM. * linux/tile/syscallent1.h: mmap2 is sys_mmap_4koff.

* Remove wrong x32-specific lseekDenys Vlasenko2013-02-17

| | | | | | | | | | | | * mem.c (sys_old_mmap): For Ia64 and 32-bit personality of x86-64, copy narrow parameters from userspace by single umove, not by six separate ones; then assign them to long u_arg[i]. For SH[64], avoid copying of tcp->u_arg.
