* Fix {get,set}rlimit decoding with unreliable SIZEOF_RLIM_THEADmasterJames Hogan2014-05-21
| | | | | | | | | | | | | | When strace is built with large file support definitions in CFLAGS (as may be provided by buildroot) the C library headers may expose a 64-bit rlim_t even though the struct rlimit fields used by the system call interface are only 32-bit. The SIZEOF_RLIM_T will then be 8 which results in bad decoding of the getrlimit and setrlimit syscalls. This is fixed by replacing unreliable SIZEOF_RLIM_T based checks with checks for current_wordsize. Signed-off-by: James Hogan <james.hogan@imgtec.com> Signed-off-by: Dmitry V.

* Assume that <sys/ptrace.h> provides a valid ptrace prototypeDmitry V. Levin2013-11-13
| | | | | | | | | | | | We used to explicitly list architectures where <sys/ptrace.h> from glibc is known to provide a valid prototype for ptrace, and use a homegrown replacement for all the rest. Situation seems to be better nowadays, glibc is not the only libc available, so let's use ptrace prototype from <sys/ptrace.h> by default, leaving the replacement for rare broken cases if any. * defs.h: Use ptrace prototype workaround iff NEED_PTRACE_PROTOTYPE_WORKAROUND is defined.
* Stop using _LFS64_LARGEFILEDmitry V. Levin2013-11-12
| | | | | | | | | | | There is only one place left in the code where strace guesses whether libc provides LFS64 functions and structures. The most natural thing to do there is to check for _LARGEFILE64_SOURCE - the macro provided by glibc. Other libc implementations that provide nondegenerate LFS64 interfaces are expected to define this macro as well. * defs.h (_LFS64_LARGEFILE): Remove. * strace.c: Use _LARGEFILE64_SOURCE instead of _LFS64_LARGEFILE.

* 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).

| | | | | | | | | | | | | | | | | | | | 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 MetaJames Hogan2013-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Eliminate MAX_QUALS, make qualifier array dynamicDenys Vlasenko2013-02-22
| | | | | | | | | | | | | | | | | | | | | | | MAX_QUALS was 2048, even though most arches used less than 500 entries in it. MAX_QUALS had to be maintained by hand to be higher than syscall count. It also limited the highest possible fd to track. This change makes qual_flagsN[] arrays start sized to the required minimum (number of syscalls) and grow dynamically if user requested -e read=BIGNUM. As a precaution, BIGNUM should be < 2^15, but this limit can be raised with no cost for normal strace invocations. qual_flags is now a define to qual_vec[current_personality]. As a bonus, this patch aliases sysent, errnoent, signalent, ioctlent names in one-personality arches to their corresponding <foo>0 arrays, removing one indirection level. text data bss dec hex filename 244471 700 12928 258099 3f033 strace.t7/strace 244627 680 10860 256167 3e8a7 strace.t8/strace Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By adding tcp->s_ent pointer tot syscall table entry, we can replace sysent[tcp->scno] references by tcp->s_ent.

* ARM: make it one-personality archDenys Vlasenko2013-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM in fact _is_ one personality. We had two personalities for it because it has a handful of syscalls with huge scnos (0x000f00xx). Extending syscall table to have [0x000f0005] index is of course not a good idea. Someone decided to handle that by having a separate personality just for these syscalls. But multi-personality arch does a bit more work in other parts. This patch is another alternative: "move" 0x000f00nn syscalls down to the entries just above last ordinary syscall, by manipulating scno if it falls into the 0x000f00xx range. In order to not worsen genuine undefined scnos' printing, the code remaps scno back to actual value before printing "syscall_NNN" string. * defs.h: Remove multi-reprsonality defines from ARM. * syscall.c (shuffle_scno): New function.
