2df03c494eb3c36c4178eba35c374831031d1a58 11-Nov-2013 Denys Vlasenko <dvlasenk@redhat.com> Stop using external libaio.h.

This change incorporates a partial copy instead
of using external libaio.h.
Why?
Because we want to properly decode 32-bit aio calls
by 64-bit strace. For that, we need more definitions than
libaio.h provides.
(These defs are not done yet, but will eventually be done).
Keeping our local 32-bit compat defs in sync with libaio.h
_without seeing libaio structs_ is hard/more bug prone.
A smaller benefit is that we don't need libaio installed.

abd2fda38003f61f50e5b4ed4f77f7997d7172ac 11-Nov-2013 Denys Vlasenko <dvlasenk@redhat.com> sys_io_submit: simplify iocb_cmd_lookup() helper.

This helper returns two values (a string and an enum).
The caller prints the string. It's simpler to just print
the string in the caller itself. This eliminates
"return by reference" and more importantly, an intermediate
static string buffer for the string result.

Since function of the helper is different now,
it is renamed to tprint_lio_opcode().

The program may use a very large nr but supply either outright
invalid iocbpp[], or one with far fewer elements than nr.
We used to try reading iocbpp[i] until i == nr.
With this change, we stop on the first failure.

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.

glibc in _FORTIFY_SOURCE mode raises SIGABRT when descriptor greater
or equal to FD_SETSIZE is passed to FD_ISSET. Select family syscalls,
however, can legitimately accept such descriptors. To overcome this
limitation, we have to replace FD_ISSET with an equivalent that imposes
no such restrictions.

* desc.c (decode_select): Actually print arg[0] as int on entering
syscall. When arg[0] is negative, do not attempt to fetch and decode
descriptor sets on entering syscall, kernel will reject it anyway.

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.

5e133aa68498626afdbdcf29e22300257a21bf57 18-Jul-2013 Denys Vlasenko <dvlasenk@redhat.com> Fix sigset printing via print_sigset().

Replace print_sigset() with print_sigset_addr_len(),
which takes not only addr, but also len parameter.
This allows us to drop "do we need to print RT signals?" parameter,
and this fixes RT signals printing in many syscalls.

sys_epoll_pwait: print RT signals too, print sigmask size argument.

sys_sigprocmask: print_sigset -> print_sigset_addr_len(current_wordsize),
no change in functionality.

sys_sigpending: use print_sigset_addr_len(current_wordsize)
instead of open-coding it.

sys_rt_sigprocmask: use print_sigset_addr_len instead of open-coding it.
sys_rt_sigpending: ditto.
sys_rt_sigsuspend: ditto.
sys_rt_sigtimedwait: ditto.

do_signalfd: print_sigset -> print_sigset_addr_len. This fixes
RT signals printing (wasn't showing them before).

sys_ppoll: ditto.

copy_sigset_len() is folded into its only user, print_sigset_addr_len(),
and copy_sigset() is gone.

While at it, checked kernel sources and noted where kernel enforces
sigset_size == NSIG / 8 (== sizeof(kernel_sigset_t)),
and where it allows word-sized sigset_size ([rt_]sigpending).

8435d672ebbc318648a54beef1d491f1ce0531a3 18-Feb-2013 Denys Vlasenko <vda.linux@googlemail.com> Remove code which supports systems with long long off_t.

While looking at mmap mess, did experimenting in order
to figure out what gets used when.

Tried building armv4tl, armv5l, armv6l, mips, mipsel, i686,
x86_64 and none of they have long long off_t,
which isn't suprprising: we aren't using glibc defines
which enable that.

Moreover, we SHOULD NOT use off_t in syscall decode!
Its size depends on libc, not on arch! I.e. it is essentially
unpredictable and can even in theory vary on the same arch
with different libc.

We should use longs or long longs, in a way which matches
architectural ABI for the given syscall. There are usually
*at most* two permutations, no need to add yet another variable
(sizeof(off_t)) to the mix.

This change removes almost all HAVE_LONG_LONG_OFF_T conditionals,
which will reveal further possible simplifications.

Another trivial changes here are fixes for directive indentation.
