When process_vm_readv fails with EPERM, try PTRACE_PEEKDATA
process_vm_readv() and ptrace(PTRACE_PEEKDATA) have inconsistent access
control rules wrt traced processes: process_vm_readv() is more likely to
fail with EPERM than ptrace(PTRACE_PEEKDATA) when tracing a process that
has execve'd a privileged executable.
* util.c (umoven, umovestr): If process_vm_readv returned EPERM,
fall back to ptrace(PTRACE_PEEKDATA).

Fix select decoding on e.g. 32-bit ppc process by 64-bit strace.
Added next_set_bit() function which finds the next set bit,
properly taking into account word size of the traced process.
Use it in decode_select() instead of fd_isset().
Also, properly round fdsize up to word size of traced process,
not to strace's word size.

Open-code isprint(c) and isspace(c)
We don't call setlocale, thus we always use C locale.
But libc supports various other locales, and therefore
its ctype interface is general and at times inefficient.
For example, in glibc these macros result in function call,
whereas for e.g. isprint(c) just c >= ' ' && c <= 0x7e
suffices.
By open-coding ctype checks (we have only 4 of them)
we avoid function calls, we get smaller code:
text data bss dec hex filename
245127 680 5708 251515 3d67b strace_old
245019 676 5708 251403 3d60b strace
and we don't link in ctype tables (beneficial for static builds).

Add support for Imagination Technologies Meta
Add support for Imagination Technologies Meta architecture (the
architecture/ABI is usually referred to as metag in code). The Meta
Linux kernel port is in the process of being upstreamed for v3.9 so it
uses generic system call numbers.
sys_lookup_dcookie writes a filename to buffer argument, so I've set
TF flag.
nfsservctl appears to be set to sys_ni_syscall in asm-generic/unistd.h
so I've left it blank.
truncate64/ftruncate64/pread64/pwrite64/readahead have unaligned 64bit
args which are packed tightly on metag, so less arguments on metag.
fchdir/llseek takes a file descriptor so s/TF/TD/
sync_file_range has 2 64bit args so uses 6 args, so s/4/6/
timerfd_create/msgget/msgctl/msgrcv/semget/segtimedop/semop/shmget/
shmctl/shmat/shmdt/recvmsg/migrate_pages have different number of args.
oldgetrlimit is just getrlimit for metag.
add TM flag to various memory syscalls.
metag doesn't directly use sys_mmap_pgoff for mmap2.
prlimit64/process_vm_readv/process_vm_writev take a pid so add TP flag.
fanotify_init doesn't appear to take a file descriptor so remove TD.

Make umoven report success as 0, not >=0, stop returning success on partial reads
umoven() uses process_vm_readv() when available but it returns the
return value of that syscall, which is the number of bytes copied,
while its callers expect it to simply return zero on success.
It was causing syscalls that take a user-space argument to print
the abbreviated version, e.g.:
epoll_ctl(5, EPOLL_CTL_ADD, 10, {...})
Instead of:
epoll_ctl(5, EPOLL_CTL_ADD, 10, {EPOLLIN, {u32=10, u64=10}})

Fix a bug in dumpstr (no null termination). Essentially rewrote dumpstr
This is a 14 year old bug (!).
It wasn't biting us merely because outstr[80] was static, thus ended up
in bss and whatever was after it "accidentally" provided the NUL byte.
When dumpstr was changed to use on-stack buffer, the bug reared its ugly head.
This is a rewrite which is smaller and should be significantly faster
for _long_ strings.

Eliminate many SCNO_IS_VALID checks
By adding tcp->s_ent pointer tot syscall table entry,
we can replace sysent[tcp->scno] references by tcp->s_ent.
More importantly, we may ensure that tcp->s_ent is always valid,
regardless of tcp->scno value. This allows us to drop
SCNO_IS_VALID(tcp->scno) checks before we access syscall
table entry.
We can optimize (qual_flags[tcp->scno] & QUAL_foo) checks

Add tilegx support to strace
tilegx support has been in the kernel since 3.0.
In addition, fix some issues with the tilepro support already
present in strace, primarily the decision to use the
<asm/unistd.h> numbering space for system calls.
* defs.h [TILE]: Include <asm/ptrace.h> and provide an extern
struct pt_regs tile_regs for efficiency. Provide compat 32-bit
personality via SUPPORTED_PERSONALITIES, PERSONALITY0_WORDSIZE,
PERSONALITY1_WORDSIZE, and DEFAULT_PERSONALITY.

* linux/tile/ioctlent1.h: New file, includes linux/ioctlent.h.
* linux/tile/signalent1.h: New file, includes linux/signalent.h.
* linux/tile/syscallent.h: Update with new asm-generic syscalls.
The version previously committed was the from the first tile patch
to LKML, which subsequently was changed to use <asm-generic/unistd.h>.
* linux/tile/syscallent1.h: Copy from linux/tile/syscallent.h.
* mem.c (addtileflags) [TILE]: use %ld properly for a "long" variable.
* process.c [TILE]: Choose clone arguments correctly and properly
suppress all "struct user" related offsets in user_struct_offsets.
* signal.c [TILE]: Use tile_regs not upeek.
* syscall.c (update_personality) [TILE]: Print mode.
(PT_FLAGS_COMPAT) [TILE]: Provide if not in system headers.
(tile_regs) [TILE]: Define 'struct pt_regs' variable to hold state.
(get_regs) [TILE]: use PTRACE_GETREGS to set tile_regs rather than using upeek.
(get_scno) [TILE]: Set personality.
(get_syscall_args) [TILE]: Use tile_regs.
(get_syscall_result) [TILE]: Update tile_regs.
(get_error) [TILE]: Use tile_regs.
(printcall) [TILE]: Print pc.
(arg0_offset, arg1_offset, restore_arg0, restore_arg1) [TILE]:

Optimize out PTRACE_PEEKUSER with -i
strace -i was fetching PC with a separate PEEKUSER
despite having GETREGS data:
ptrace(PTRACE_GETREGS, 22331, 0, 0x8087f00) = 0
ptrace(PTRACE_PEEKUSER, 22331, 4*EIP, [0x80dd7b7]) = 0
write(3, "[080dd7b7] ioctl(0, SNDCTL_TMR_T"..., 82) = 82
ptrace(PTRACE_SYSCALL, 22331, 0, SIG_0) = 0
Now it does this:
ptrace(PTRACE_GETREGS, 22549, 0, 0x8087ea0) = 0
write(3, "[080dd7b7] ioctl(0, SNDCTL_TMR_T"..., 82) = 82
ptrace(PTRACE_SYSCALL, 22549, 0, SIG_0) = 0
Analogous improvement in sys_sigreturn() is also implemented.
* defs.h: Declare extern struct pt_regs regs for SPARC[64] and ARM.
Declare clear_regs(), get_regs() and get_regs_error flag variable.
* strace.c (trace): Call get_regs(pid) as soon as we know the tcb
and that it is stopped.
* syscall.c (get_regs): New function. Used to fetch registers early,
just after tracee has stopped.
(printcall): Move it here from util.c. Use global regs.REG data,
if available on the arch, instead of re-fetching it.
(get_scno): Use global regs.REG data.
(get_syscall_result): Likewise.
* signal.c (sys_sigreturn): Likewise.
* util.c (printcall): Moved to syscall.c.

Add state argument to change_syscall and fix SPARC
Add a state argument to change_syscall() so that SPARC can modify that
instead of read-modify-writing the whole register set. This function is
always called within an arg_setup/arg_finish_change sequence which on
certain architectures like SPARC will also be doing a read-modify-write.
This prevents the second write (from arg_finish_change) from undoing the
effects of the change_syscall call.
* util.c (change_syscall): Move below definition of arg_setup_state.
Add state argument.
[SPARC || SPARC64] Change to set state->u_regs[U_REG_G1] rather than
read-modify-writing it with PTRACE_GETREGS and PTRACE_SETREGS.

util: fix building when glibc has a stub process_vm_readv
If you have a newer glibc which provides process_vm_readv, but it is built
against older kernel headers which lack __NR_process_vm_readv, the library
will contain a stub implementation that just returns ENOSYS. Autoconf
checks for this case explicitly and will declare it as unavailable. So we
end up in a case where the headers provide the prototype, but autoconf has
not defined HAVE_PROCESS_VM_READV, so we hit the same build failure again:
util.c:738:16: error: static declaration of 'process_vm_readv' follows non-static declaration
/usr/include/bits/uio.h:58:16: note: previous declaration of 'process_vm_readv' was here
So rename our local function to something unique, and add a define so the
callers all hit the right place.
* util.c (strace_process_vm_readv): Rename from process_vm_readv.
(process_vm_readv): Define to strace_process_vm_readv.

Pass addr=0 instead of 1 into restarting ptrace calls
While we are at it, fold do_ptrace into its lone caller.
We no longer set tcp->ptrace_errno = ESRCH on ESRC error in upeek.
Other code paths where ptrace fails wern't doing it, and the code which
checks tcp->ptrace_errno even assumes it is never set to ESRCH.
(It was me who added this code sometime ago, so it was my fault
that it was a bit messy)
I ran sigkill_rain test and verified that unfinished syscalls are
still handled correctly.

Add experimental code to use PTRACE_SEIZE, disabled by default
All new code is predicated on "ifdef USE_SEIZE". If it is not defined,
behavior is not changed.
If USE_SEIZE is enabled and run-time check shows that PTRACE_SEIZE works, then:
- All attaching is done with PTRACE_SEIZE + PTRACE_INTERRUPT.
This means that we no longer generate (and possibly race with) SIGSTOP.
- PTRACE_EVENT_STOP will be generated if tracee is group-stopped.
When we detect it, we issue PTRACE_LISTEN instead of PTRACE_SYSCALL.
This leaves tracee stopped. This fixes the inability to SIGSTOP or ^Z
a straced process.
* defs.h: Add commented-out "define USE_SEIZE 1" and define PTRACE_SEIZE
and related constants.
* strace.c: New variable post_attach_sigstop shows whether we age going
to expect SIGSTOP on attach (IOW: are we going to use PTRACE_SEIZE).
(ptrace_attach_or_seize): New function. Uses PTRACE_ATTACH or
PTRACE_SEIZE + PTRACE_INTERRUPT to attach to given pid.
(startup_attach): Use ptrace_attach_or_seize() instead of ptrace(PTRACE_ATTACH).
(startup_child): Conditionally use alternative attach method using PTRACE_SEIZE.
(test_ptrace_setoptions_followfork): More robust parameters to PTRACE_TRACEME.
(test_ptrace_seize): New function to test whether PTRACE_SEIZE works.
(main): Call test_ptrace_seize() while initializing.
(trace): If PTRACE_EVENT_STOP is seen, restart using PTRACE_LISTEN in order
to not let tracee run.
* process.c: Decode PTRACE_SEIZE, PTRACE_INTERRUPT, PTRACE_LISTEN.
* util.c (ptrace_restart): Add "LISTEN" to a possible error message.

Use process_vm_readv instead of PTRACE_PEEKDATA to read data blocks
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.
Result of "time strace -oLOG ls -l /usr/lib >/dev/null":
before patch: 0.372s
After patch: 0.262s
* util.c (process_vm_readv): Wrapper to call process_vm_readv syscall.

Replace many more bare ptrace calls with calls to wrappers
which do proper error-checking and set tcp->ptrace_errno.
In some cases, missing error checking is added.
Error handling for trace_syscall() failures and other cases
where tcp->ptrace_errno is nonzero is cleaned up a bit
and made more verbose if we see error other than ESRC.
Some comments are added or expanded.
* defs.h: Declare ptrace_cmds[]. Modify do_ptrace
declaration (last parameter is long, not void *).
* process.c: Make ptrace_cmds[] non-static.
(change_syscall): Use do_ptrace() instead of bare ptrace().
* signal.c: Use do_ptrace() instead of bare ptrace().
* strace.c: Update trace_syscall() failure handling.
* syscall.c: Use do_ptrace() instead of bare ptrace().
* util.c: Use do_ptrace() instead of bare ptrace().
Update do_ptrace() wrapper.
(str_PTRACE_xxx): New function - helper returning "PTRACE_xxx".
(do_ptrace_peekdata): New function - wrapper for PTRACE_PEEKDATA
(do_ptrace5): New function - wrapper for 5-argument ptrace calls.

Two cleanups: tcb table expansion failure is not really a survivable
event, we do not have any viable way to continue. No wonder most
places where that is detected have FIXMEs.
It's way simpler to treat as fatal failure, and handle it inside
tcb table expansion finctions.
Second cleanup: tidy up haphazard locations of a few externs.
* defs.h: Change return type of expand_tcbtab() to void.
Declare change_syscall().
* process.c: Change all callsites of alloctcb(), alloc_tcb() and
fork_tcb(), removing now-redundant error checks.

* strace.c: Move extern declarations out of function bodies.

(expand_tcbtab): Change return type to void - it can't fail now.

This patch does not change any logic.
It merely passes tcp pointer to upeek instead of pid.
This is needed if one wants to check or change
some tcp fields.
I have patches which require this. I can imagine someone else
eventually needing to look at tcp for completely orthogonal reasons.
