truss: split counting of syscalls and syscall calling convention This change is a refactoring cleanup to improve support for compat32 syscalls (and compat64 on CHERI systems). Each process ABI now has it's own struct sycall instead of using one global list. The list of all syscalls is replaced with a list of seen syscalls. Looking up the syscall argument passing convention now interates over the fixed-size array instead of using a link-list that's populated on startup so we no longer need the init_syscall() function. The actual functional changes are in D27625. Reviewed By: jhb Differential Revision: https://reviews.freebsd.org/D27636

Use PT_GET_SC_ARGS and PT_GET_SC_RET in truss. This removes all of the architecture-specific functions from truss. A per-ABI structure is still needed to map syscall numbers to names and FreeBSD errno values to ABI error values as well as hold syscall counters. However, the linker set of ABI structures is now replaced with a simple table mapping ABI names to structures. This approach permits sharing the same ABI structure among separate names such as i386 a.out and ELF binaries as well as ELF v1 vs ELF v2 for powerpc64. A few differences are visible due to using PT_GET_SC_RET to fetch the error value of a system call. Note that ktrace/kdump have had the "new" behaviors for a long time already: - System calls that return with EJUSTRETURN or ERESTART will now be noticed and logged as such. Previously sigreturn (which uses EJUSTRETURN) would report whatever random value was in the register holding errno from the previous system call for example. Now it reports EJUSTRETURN. - System calls that return errno as their error value such as posix_fallocate() and posix_fadvise() now report non-zero return values as errors instead of success with a non-zero return value.

Decode kevent structures logged via ktrace(2) in kdump. - Add a new KTR_STRUCT_ARRAY ktrace record type which dumps an array of structures. The structure name in the record payload is preceded by a size_t containing the size of the individual structures. Use this to replace the previous code that dumped the kevent arrays dumped for kevent(). kdump is now able to decode the kevent structures rather than dumping their contents via a hexdump. One change from before is that the 'changes' and 'events' arrays are not marked with separate 'read' and 'write' annotations in kdump output. Instead, the first array is the 'changes' array, and the second array (only present if kevent doesn't fail with an error) is the 'events' array. For kevent(), empty arrays are denoted by an entry with an array containing zero entries rather than no record. - Move kevent decoding tables from truss to libsysdecode. This adds three new functions to decode members of struct kevent: sysdecode_kevent_filter, sysdecode_kevent_flags, and sysdecode_kevent_fflags. kdump uses these helper functions to pretty-print kevent fields. - Move structure definitions for freebsd11 and freebsd32 kevent structures to <sys/event.h> so that they can be shared with userland. The 32-bit structures are only exposed if _WANT_KEVENT32 is defined. The freebsd11 structures are only exposed if _WANT_FREEBSD11_KEVENT is defined. The 32-bit freebsd11 structure requires both. - Decode freebsd11 kevent structures in truss for the compat11.kevent() system call. - Log 32-bit kevent structures via ktrace for 32-bit compat kevent() system calls. - While here, constify the 'void *data' argument to ktrstruct().

Rework syscall structure lookups. Avoid always using an O(n^2) loop over known syscall structures with strcmp() on each system call. Instead, use a per-ABI cache indexed by the system call number. The first 1024 system calls (which should cover all of the normal system calls in currently-supported ABIs) use a flat array indexed by the system call number to find system call structure. For other system calls, a linked list of structures storing an integer to structure mapping is stored in the ABI. The linked list isn't very smart, but it should only be used by buggy applications invoking unknown system calls. This also fixes handling of unknown system calls which currently trigger a NULL pointer dereference. Reviewed by: kib MFC after: 2 weeks

Move mksubr from kdump into libsysdecode. Restructure this script so that it generates a header of tables instead of a source file. The tables are included in a flags.c source file which provides functions to decode various system call arguments. For functions that decode an enumeration, the function returns a pointer to a string for known values and NULL for unknown values. For functions that do more complex decoding (typically of a bitmask), the function accepts a pointer to a FILE object (open_memstream() can be used as a string builder) to which decoded values are written. If the function operates on a bitmask, the function returns true if any bits were decoded or false if the entire value was valid. Additionally, the third argument accepts a pointer to a value to which any undecoded bits are stored. This pointer can be NULL if the caller doesn't care about remaining bits. Convert kdump over to using decoder functions from libsysdecode instead of mksubr. truss also uses decoders from libsysdecode instead of private lookup tables, though lookup tables for objects not decoded by kdump remain in truss for now. Eventually most of these tables should move into libsysdecode as the automated table generation approach from mksubr is less stale than the static tables in truss. Some changes have been made to truss and kdump output: - The flags passed to open() are now properly decoded in that one of O_RDONLY, O_RDWR, O_WRONLY, or O_EXEC is always included in a decoded mask. - Optional arguments to open(), openat(), and fcntl() are only printed in kdump if they exist (e.g. the mode is only printed for open() if O_CREAT is set in the flags). - Print argument to F_GETLK/SETLK/SETLKW in kdump as a pointer, not int. - Include all procctl() commands. - Correctly decode pipe2() flags in truss by not assuming full open()-like flags with O_RDONLY, etc. - Decode file flags passed to *chflags() as file flags (UF_* and SF_*) rather than as a file mode. - Fix decoding of quotactl() commands by splitting out the two command components instead of assuming the raw command value matches the primary command component. In addition, truss and kdump now build without triggering any warnings. All of the sysdecode manpages now include the required headers in the synopsis.

Several changes to truss. - Refactor the interface between the ABI-independent code and the ABI-specific backends. The backends now provide smaller hooks to fetch system call arguments and return values. The rest of the system call entry and exit handling that was previously duplicated among all the backends has been moved to one place. - Merge the loop when waiting for an event with the loop for handling stops. This also means not emulating a procfs-like interface on top of ptrace(). Instead, use a single event loop that fetches process events via waitid(). Among other things this allows us to report the full 32-bit exit value. - Use PT_FOLLOW_FORK to follow new child processes instead of forking a new truss process for each new child. This allows one truss process to monitor a tree of processes and truss -c should now display one total for the entire tree instead of separate summaries per process. - Use the recently added fields to ptrace_lwpinfo to determine the current system call number and argument count. The latter is especially useful and fixes a regression since the conversion from procfs. truss now generally prints the correct number of arguments for most system calls rather than printing extra arguments for any call not listed in the table in syscalls.c. - Actually check the new ABI when processes call exec. The comments claimed that this happened but it was not being done (perhaps this was another regression in the conversion to ptrace()). If the new ABI after exec is not supported, truss detaches from the process. If truss does not support the ABI for a newly executed process the process is killed before it returns from exec. - Along with the refactor, teach the various ABI-specific backends to fetch both return values, not just the first. Use this to properly report the full 64-bit return value from lseek(). In addition, the handler for "pipe" now pulls the pair of descriptors out of the return values (which is the true kernel system call interface) but displays them as an argument (which matches the interface exported by libc). - Each ABI handler adds entries to a linker set rather than requiring a statically defined table of handlers in main.c. - The arm and mips system call fetching code was changed to follow the same pattern as amd64 (and the in-kernel handler) of fetching register arguments first and then reading any remaining arguments from the stack. This should fix indirect system call arguments on at least arm. - The mipsn32 and n64 ABIs will now look for arguments in A4 through A7. - Use register %ebp for the 6th system call argument for Linux/i386 ABIs to match the in-kernel argument fetch code. - For powerpc binaries on a powerpc64 system, fetch the extra arguments on the stack as 32-bit values that are then copied into the 64-bit argument array instead of reading the 32-bit values directly into the 64-bit array.

- Decode the arguments for several signal-related system calls: sigpending, sigqueue, sigreturn, sigsuspend, sigtimedwait, sigwait, sigwaitinfo, and thr_kill. - Print signal sets as a structure (with {}'s) and in particular use this to differentiate empty sets from a NULL pointer. - Decode arguments for some other system calls: issetugid, pipe2, sysarch (operations are only decoded for amd64 and i386), and thr_self.

Decode the arguments passed to the *at() family of system calls. This is especially useful now that libc's open() always calls openat(). While here, fix a few other things: - Decode the mode argument passed to access(), eaccess(), and faccessat(). - Decode the atfd paramete to pretty-print AT_FDCWD. - Decode the special AT_* flags used with some of the *at() system calls. - Decode arguments for fchmod(), lchmod(), fchown(), lchown(), eaccess(), and futimens(). - Decode both of the timeval structures passed to futimes() instead of just the first one.

Remove dead code from umtx support: - Retire long time unused (basically always unused) sys__umtx_lock() and sys__umtx_unlock() syscalls - struct umtx and their supporting definitions - UMUTEX_ERROR_CHECK flag - Retire UMTX_OP_LOCK/UMTX_OP_UNLOCK from _umtx_op() syscall __FreeBSD_version is not bumped yet because it is expected that further breakages to the umtx interface will follow up in the next days. However there will be a final bump when necessary. Sponsored by: EMC / Isilon storage division Reviewed by: jhb

Extend the support for exempting processes from being killed when swap is exhausted. - Add a new protect(1) command that can be used to set or revoke protection from arbitrary processes. Similar to ktrace it can apply a change to all existing descendants of a process as well as future descendants. - Add a new procctl(2) system call that provides a generic interface for control operations on processes (as opposed to the debugger-specific operations provided by ptrace(2)). procctl(2) uses a combination of idtype_t and an id to identify the set of processes on which to operate similar to wait6(). - Add a PROC_SPROTECT control operation to manage the protection status of a set of processes. MADV_PROTECT still works for backwards compatability. - Add a p_flag2 to struct proc (and a corresponding ki_flag2 to kinfo_proc) the first bit of which is used to track if P_PROTECT should be inherited by new child processes.

Create the altix project branch. The altix project will add support for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.

Add a -s flag for the same functionality as strace. Introduce a Name type which is a String type that has no -s limitations applied to it. Change most Strings in the code to Names and add a few extra syscalls, namely munmap, read, rename and symlink. This was enough to facilitate following file descriptor allocations in the code more easily and getting a hint at what's being read/written from/to files. More syscalls should really be added. While here, fix an off-by-one bug in the buffer truncation code and add a fflush so that truss's output reflects the syscall that the program is stuck in.

Support readlink(2) better. Readlink does not nul terminate the result buffer, so we need to format it ourselves. The problem is that the length is stored as the return value from readlink, so we need to pass the return value from our syscall into print_arg. Motivated by: truss garbage on my screen from reading /etc/malloc.conf.

Add support for decoding Timespec, Timeval, Itimerval, Pollfd, Fd_set and Sigaction structures. Use these for printing the arguments to sigaction(), nanosleep(), select(), poll(), gettimeofday(), clock_gettime(), recvfrom(), getitimer() and setitimer(). This is based on Dan's patch from the PR but I've hacked it for style and some other issues. While Dan has checked this patch, any goofs are probably my fault. (The PR also contains support for the dual return values of pipe(). These will follow once I've ported that support to platforms other than i386.)

Port truss(1) to 64-bit architectures: o Syscall return values do not fit in int on 64-bit architectures. Change the type of retval in <arch>_syscall_exit() to long and change the prototype of said function to return a long as well. o Change the prototype of print_syscall_ret() to take a long for the return address and change the format string accordingly. o Replace the code sequence tmp = malloc(X); sprintf(tmp, format, ...); with X by definition too small on 64-bit platforms by asprintf(&tmp, format, ...); With these changes the output makes sense again, although it does mess up the tabulation on ia64. Go widescreen... Not tested on: alpha, sparc64.
