* fanotify_mark: fix number of args for 32bit archesMike Frysinger2013-09-11
| | | | | | | | | | | | | | | | | | | | | | | | The fanotify_mark func takes a 64bit mask, so 32bit arches have to split it up into two fields.

* 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.

* Shrink space needed by undefined syscalls in syscall tables.Denys Vlasenko2012-03-19
| | | | | | | | | | | | | | | | | | | | | | | | Undefined syscall looked like this before this change: { 5, 0, printargs, "SYS_53" }, That is, "SYS_53" string had to be allocated and stored in strace binary. Since now SCNO_IN_RANGE() macro requires sysent[scno].sys_func != NULL for valid syscalls, we can replace printargs with NULL in such lines and make them "invalid", thus not requiring syscall name string.

* Remove underscores from a few syscall names which have themDenys Vlasenko2012-03-17
| | | | | | | | | | | | | | | | | | | | Affected names are "_newselect", "_llseek", "_sysctl". I see no apparent reason why they have leading underscores. Moreover, some arches have underscored names and some have non-underscored ones. This is not consistent. I verified that every architectire I touched did not have a similarly named syscall without underscore, thus this change does not introduce new ambiquities. I left "_exit" untouched for now, but the same points stand for it too: some architectures use "exit" and no one complains. So why many arches are using "_exit"? * linux/*/syscallent.h: Remove underscores from displayed syscall names for _newselect, _llseek, _sysctl.

* Use process_vm_readv instead of PTRACE_PEEKDATA to read data blocksDenys Vlasenko2012-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we use PTRACE_PEEKDATA to read things like filenames and data passed by I/O syscalls. PTRACE_PEEKDATA gets one word per syscall. This is VERY expensive. For example, in order to print fstat syscall, we need to perform more than twenty trips into kernel to fetch one struct stat! Kernel 3.2 got a new syscall, process_vm_readv(), which can be used to copy data blocks out of process' address space. This change uses it in umoven() and umovestr() functions if possible, with fallback to old method if process_vm_readv() fails. If it returns ENOSYS, we don't try to use it anymore, eliminating overhead of trying it on older kernels.

* Set saner MAX_ARGS (6 or 8) for X86_64 and I386Denys Vlasenko2011-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that tcp->u_args[MAX_ARGS] array is way larger than I'd expect: for all arches except HPPA it has 32 (!) elements. I looked at the code and so far I spotted only one abuser of this fact: sys_sigreturn. On several arches, it saves sigset_t into tcp->u_args[1...N] on entry and prints it on exit, a-la memcpy(&tcp->u_arg[1], &sc.oldmask[0], sizeof(sigset_t)) The problem here is that in glibc sigset_t is insanely large: 128 bytes, and using sizeof(sigset_t) in memcpy will overrun &tcp->u_args[1] even with MAX_ARGS == 32: On 32 bits, sizeof(tcp->u_args) == 32*4 == 128 bytes! We may already have a bug there! This commit changes the code to save NSIG / 8 bytes only. NSIG can't ever be > 256, and in practice is <= 129, thus NSIG / 8 is <= 16 bytes == 4 32-bit words, and even MAX_ARGS == 5 should be enough for saving signal masks. * defs.h: Reduce MAX_ARGS for X86_64 and I386 from 32 to 8 for FreeBSD and to 6 for everyone else. Add comment about current state of needed MAX_ARGS. * signal.c: Add comment about size of sigset_t. (sprintsigmask): Reduce static string buffer from 8k to 2k.

* Don't display bogus parameter for sigreturn syscallDenys Vlasenko2011-06-09
| | | | | | | | | | | | | | * linux/*/syscallent.h: For those arches which use sys_sigreturn, not printargs, to show [rt_]sigreturn syscall, change number of arguments from 1 to 0: sys_sigreturn function doesn't use syscall parameters. (I guess kernel doesn't actually _have_ any parameters for this syscall, at least on these architectures). Do the same change for I386 and x86-64 even though they use printargs: I looked at kernel code and syscall definitely doesn't have any parameters on these arches. (I hesitate to change 1 to 0 params for arches I don't know - it is remotely possible some of them do have a parameter for this syscall). Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This unifies all the ioctlent.h's in the linux subdir while still allowing each arch to maintain its own minor list. The basic method is: - each arch has linux/<arch>/ioctlent.h.in which defines only the arch-specific ioctls; - linux/ioctlent.h.in which defines only the common ioctls; - at build time, these two headers are combined and sorted to produce the linux/ioctlent.h file.
