* Move io_* syscalls decoding to a separate fileDmitry V. Levin2013-11-11
| | | | | | | * desc.c (sys_io_setup, sys_io_destroy, sys_io_submit, sys_io_cancel, sys_io_getevents, declarations from libaio.h): Move to ... * aio.c: new file. * Makefile.am (strace_SOURCES): Add aio.c.
* Stop using external libaio.h.Denys Vlasenko2013-11-11
| | | | | | | | | | | | | | | 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.

* sys_io_submit: simplify iocb_cmd_lookup() helper.Denys Vlasenko2013-11-11
| | | | | | | | | | | | | 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(). Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com>
* sys_io_submit: stop traversing iocb vector after first failure.Denys Vlasenko2013-11-11
| | | | | | | | | 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. Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com>
* Fix select decoding on e.g. 32-bit ppc process by 64-bit strace.Denys Vlasenko2013-11-09
| | | | | | | | | | 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. Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com>

* Fix select decoding for glibc in _FORTIFY_SOURCE modeDmitry V. Levin2013-11-05
| | | | | | | | | | | 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 (fd_isset): New function. (decode_select): Use it instead of FD_ISSET.
* More select decoding fixesDmitry V. Levin2013-11-05
| | | | | | | | * 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. On exiting syscall, stop checking descriptor sets as soon as all returned descriptors are found.

* 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.

* Fix sigset printing via print_sigset().Denys Vlasenko2013-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Remove code which supports systems with long long off_t.Denys Vlasenko2013-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. * mem.c: Remove code conditional on HAVE_LONG_LONG_OFF_T.

| | | | | | | * desc.c: Do not compile code that uses struct iocb unless HAVE_LIBAIO_H is set. Reported-by: Denys Vlasenko <dvlasenk@redhat.com>
* Enhance io_submit() decodingAndi Kleen2011-06-13
| | | | | | | | | strace didn't decode important fields in the iocb passed to io_submit. This patch changes the code to dump them all. Also it prefixes the fields with names to make it easier to read. * desc.c (iocb_cmd_lookup, print_common_flags): New functions. (sys_io_submit): New iocb decoder.
* Whitespace cleanups. no code changes.Denys Vlasenko2011-06-07
