truss: fix handling of 64-bit arguments/return values for compat32 Deciding whether to combine two values to a 64-bit one should be based on the process ABI, and not dependent on whether truss is compiled for an LP64 ABI. This is a follow-up cleanup for D27625. I found this while looking for uses of the `__LP64__` macro (since using this is wrong for CHERI systems). Test Plan: truss still works. Since I tested on AMD64 and all syscalls in the trace have their quad argument last there was no difference in the output. Should fix output for compat32 on MIPS64 though.

truss: improved support for decoding compat32 arguments Currently running `truss -a -e` does not decode any argument values for freebsd32_* syscalls (open/readlink/etc.) This change checks whether a syscall starts with freebsd{32,64}_ and if so strips that prefix when looking up the syscall information. To ensure that the truss logs include the real syscall name we create a copy of the syscall information struct with the updated. The other problem is that when reading string array values, truss naively iterates over an array of char* and fetches the pointer value. This will result in arguments not being loaded if the pointer is not aligned to sizeof(void*), which can happens in the compat32 case. If it happens to be aligned, we would end up printing every other value. To fix this problem, this changes adds a pointer_size member to the procabi struct and uses that to correctly read indirect arguments as 64/32 bit addresses in the the compat32 case (and also compat64 on CheriBSD). The motivating use-case for this change is using truss for 64-bit programs on a CHERI system, but most of the diff also applies to 32-bit compat on a 64-bit system, so I'm upstreaming this instead of keeping it as a local CheriBSD patch.

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.

Enable iterating all sysctls, even ones with CTLFLAG_SKIP Add an "nextnoskip" sysctl that allows for listing of sysctls intended to be normally skipped for cost reasons. This makes it so the names/descriptions of those sysctls can be discovered with sysctl -aN/sysctl -ad/sysctl -at. It also makes it so children are visited when a node flagged with CTLFLAG_SKIP is explicitly requested. The intended use case is to mark the root "kstat" node with CTLFLAG_SKIP so that the extensive and expensive stats are skipped by default but may still be easily obtained without having to know them all (which may not even be possible) and request each one-by-one.

Add an shm_rename syscall Add an atomic shm rename operation, similar in spirit to a file rename. Atomically unlink an shm from a source path and link it to a destination path. If an existing shm is linked at the destination path, unlink it as part of the same atomic operation. The caller needs the same permissions as shm_unlink to the shm being renamed, and the same permissions for the shm at the destination which is being unlinked, if it exists. If those fail, EACCES is returned, as with the other shm_* syscalls. truss support is included; audit support will come later.

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.

Make timespecadd(3) and friends public The timespecadd(3) family of macros were imported from NetBSD back in r35029. However, they were initially guarded by #ifdef _KERNEL. In the meantime, we have grown at least 28 syscalls that use timespecs in some way, leading many programs both inside and outside of the base system to redefine those macros. It's better just to make the definitions public. Our kernel currently defines two-argument versions of timespecadd and timespecsub. NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define three-argument versions. Solaris also defines a three-argument version, but only in its kernel. This revision changes our definition to match the common three-argument version. Bump _FreeBSD_version due to the breaking KPI change.

Implement getrandom(2) and getentropy(3) The general idea here is to provide userspace programs with well-defined sources of entropy, in a fashion that doesn't require opening a new file descriptor (ulimits) or accessing paths (/dev/urandom may be restricted by chroot or capsicum). getrandom(2) is the more general API, and comes from the Linux world. Since our urandom and random devices are identical, the GRND_RANDOM flag is ignored. getentropy(3) is added as a compatibility shim for the OpenBSD API. truss(1) support is included. Tests for both system calls are provided. Coverage is believed to be at least as comprehensive as LTP getrandom(2) test coverage. Additionally, instructions for running the LTP tests directly against FreeBSD are provided in the "Test Plan" section of the Differential revision linked below. (They pass, of course.)

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().

Import the latest CloudABI definitions, version 0.16. The most important change in this release is the removal of the poll_fd() system call; CloudABI's equivalent of kevent(). Though I think that kqueue is a lot saner than many of its alternatives, our experience is that emulating this system call on other systems accurately isn't easy. It has become a complex API, even though I'm not convinced this complexity is needed. This is why we've decided to take a different approach, by looking one layer up. We're currently adding an event loop to CloudABI's C library that is API compatible with libuv (except when incompatible with Capsicum). Initially, this event loop will be built on top of plain inefficient poll() calls. Only after this is finished, we'll work our way backwards and design a new set of system calls to optimize it. Interesting challenges will include integrating asynchronous I/O into such a system call API. libuv currently doesn't aio(4) on Linux/BSD, due to it being unreliable and having undesired semantics.

Merge pipes and socket pairs. Now that CloudABI's sockets API has been changed to be addressless and only connected socket instances are used (e.g., socket pairs), they have become fairly similar to pipes. The only differences on CloudABI is that socket pairs additionally support shutdown(), send() and recv(). To simplify the ABI, we've therefore decided to remove pipes as a separate file descriptor type and just let pipe() return a socket pair of type SOCK_STREAM. S_ISFIFO() and S_ISSOCK() are now defined identically.

Now that all of the packaged software has been adjusted to either use Flower (https://github.com/NuxiNL/flower) for making incoming/outgoing network connections or can have connections injected, there is no longer need to keep accept() around. It is now a lot easier to write networked services that are address family independent, dual-stack, testable, etc. Remove all of the bits related to accept(), but also to getsockopt(SO_ACCEPTCONN).

Sync CloudABI compatibility against the latest upstream version (v0.13). With Flower (CloudABI's network connection daemon) becoming more complete, there is no longer any need for creating any unconnected sockets. Socket pairs in combination with file descriptor passing is all that is necessary, as that is what is used by Flower to pass network connections from the public internet to listening processes. Remove all of the kernel bits that were used to implement socket(), listen(), bindat() and connectat(). In principle, accept() and SO_ACCEPTCONN may also be removed, but there are still some consumers left. Obtained from: https://github.com/NuxiNL/cloudabi MFC after: 1 month

Upgrade to the latest sources generated from the CloudABI specification. The CloudABI specification has had some minor changes over the last half year. No substantial features have been added, but some features that are deemed unnecessary in retrospect have been removed: - mlock()/munlock(): These calls tend to be used for two different purposes: real-time support and handling of sensitive (cryptographic) material that shouldn't end up in swap. The former use case is out of scope for CloudABI. The latter may also be handled by encrypting swap. Removing this has the advantage that we no longer need to worry about having resource limits put in place. - SOCK_SEQPACKET: Support for SOCK_SEQPACKET is rather inconsistent across various operating systems. Some operating systems supported by CloudABI (e.g., macOS) don't support it at all. Considering that they are rarely used, remove support for the time being. - getsockname(), getpeername(), etc.: A shortcoming of the sockets API is that it doesn't allow you to create socket(pair)s, having fake socket addresses associated with them. This makes it harder to test applications or transparently forward (proxy) connections to them. With CloudABI, we're slowly moving networking connectivity into a separate daemon called Flower. In addition to passing around socket file descriptors, this daemon provides address information in the form of arbitrary string labels. There is thus no longer any need for requesting socket address information from the kernel itself. This change also updates consumers of the generated code accordingly. Even though system calls end up getting renumbered, this won't cause any problems in practice. CloudABI programs always call into the kernel through a kernel-supplied vDSO that has the numbers updated as well. Obtained from: https://github.com/NuxiNL/cloudabi

Add abstime kqueue(2) timers and expand struct kevent members. This change implements NOTE_ABSTIME flag for EVFILT_TIMER, which specifies that the data field contains absolute time to fire the event. To make this useful, data member of the struct kevent must be extended to 64bit. Using the opportunity, I also added ext members. This changes struct kevent almost to Apple struct kevent64, except I did not changed type of ident and udata, the later would cause serious API incompatibilities. The type of ident was kept uintptr_t since EVFILT_AIO returns a pointer in this field, and e.g. CHERI is sensitive to the type (discussed with brooks, jhb). Unlike Apple kevent64, symbol versioning allows us to claim ABI compatibility and still name the new syscall kevent(2). Compat shims are provided for both host native and compat32.

Automate the handling of QUAD_ALIGN and QUAD_SLOTS. Previously, the offset in a system call description specified the array index of the start of a system call argument. For most system call arguments this was the same as the index of the argument in the function signature. 64-bit arguments (off_t and id_t values) passed on 32-bit platforms use two slots in the array however. This was handled by adding (QUAD_SLOTS - 1) to the slot indicies of any subsequent arguments after a 64-bit argument (though written as ("{ Quad, 1 }, { Int, 1 + QUAD_SLOTS }" rather than "{ Quad, 1 }, { Int, 2 + QUAD_SLOTS - 1 }"). If a system call contained multiple 64-bit arguments (such as posix_fadvise()), then additional arguments would need to use 'QUAD_SLOTS * 2' but remember to subtract 2 from the initial number, etc. In addition, 32-bit powerpc requires 64-bit arguments to be 64-bit aligned, so if the effective index in the array of a 64-bit argument is odd, it needs QUAD_ALIGN added to the current and any subsequent slots. However, if the effective index in the array of a 64-bit argument was even, QUAD_ALIGN was omitted. This approach was messy and error prone. This commit replaces it with automated pre-processing of the system call table to do fixups for 64-bit argument offsets. The offset in a system call description now indicates the index of an argument in the associated function call's signature. A fixup function is run against each decoded system call description during startup on 32-bit platforms. The fixup function maintains an 'offset' value which holds an offset to be added to each remaining system call argument's index. Initially offset is 0. When a 64-bit system call argument is encountered, the offset is first aligned to a 64-bit boundary (only on powerpc) and then incremented to account for the second argument slot used by the argument. This modified 'offset' is then applied to any remaining arguments. This approach does require a few things that were not previously required: 1) Each system call description must now list arguments in ascending order (existing ones all do) without using duplicate slots in the register array. A new assert() should catch any future descriptions which violate this rule. 2) A system call description is still permitted to omit arguments (though none currently do), but if the call accepts 64-bit arguments those cannot be omitted or incorrect results will be displated on 32-bit systems. Tested on: amd64 and i386

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.

Import the new automatically generated system call table for CloudABI. Now that we've switched over to using the vDSO on CloudABI, it becomes a lot easier for us to phase out old features. System call numbering is no longer something that's part of the ABI. It's fully based on names. As long as the numbering used by the kernel and the vDSO is consistent (which it always is), it's all right. Let's put this to the test by removing a system call (thread_tcb_set()) that's already unused for quite some time now, but was only left intact to serve as a placeholder. Sync in the new system call table that uses alphabetic sorting of system calls. Obtained from: https://github.com/NuxiNL/cloudabi

Replace the CloudABI system call table by a machine generated version. The type definitions and constants that were used by COMPAT_CLOUDABI64 are a literal copy of some headers stored inside of CloudABI's C library, cloudlibc. What is annoying is that we can't make use of cloudlibc's system call list, as the format is completely different and doesn't provide enough information. It had to be synced in manually. We recently decided to solve this (and some other problems) by moving the ABI definitions into a separate file: https://github.com/NuxiNL/cloudabi/blob/master/cloudabi.txt This file is processed by a pile of Python scripts to generate the header files like before, documentation (markdown), but in our case more importantly: a FreeBSD system call table. This change discards the old files in sys/contrib/cloudabi and replaces them by the latest copies, which requires some minor changes here and there. Because cloudabi.txt also enforces consistent names of the system call arguments, we have to patch up a small number of system call implementations to use the new argument names. The new header files can also be included directly in FreeBSD kernel space without needing any includes/defines, so we can now remove cloudabi_syscalldefs.h and cloudabi64_syscalldefs.h. Patch up the sources to include the definitions directly from sys/contrib/cloudabi instead.

Use ptrace(2) LWP events to track threads reliably in truss. - truss can now log the system call invoked by a thread during a voluntary process exit. No return value is logged, but the value passed to exit() is included in the trace output. Arguments passed to thread exit system calls such as thr_exit() are not logged as voluntary thread exits cannot be distinguished from involuntary thread exits during a system call. - New events are now reported for thread births and exits similar to the recently added events for new child processes when following forks.

Add handling for non-native error values to libsysdecode. Add two new functions, sysdecode_abi_to_freebsd_errno() and sysdecode_freebsd_to_abi_errno(), which convert errno values between the native FreeBSD ABI and other supported ABIs. Note that the mappings are not necessarily perfect meaning in some cases multiple errors in one ABI might map to a single error in another ABI. In that case, the reverse mapping will return one of the errors that maps, but which error is non-deterministic. Change truss to always report the raw error value to the user but use libsysdecode to map it to a native errno value that can be used with strerror() to generate a description. Previously truss reported the "converted" error value. Now the user will always see the exact error value that the application sees. Change kdump to report the truly raw error value to the user. Previously kdump would report the absolute value of the raw error value (so for Linux binaries it didn't output the FreeBSD error value, but the positive value of the Linux error). Now it reports the real (i.e. negative) error value for Linux binaries. Also, use libsysdecode to convert the native FreeBSD error reported in the ktrace record to the raw error used by the ABI. This means that the Linux ABI can now be handled directly in ktrsysret() and removes the need for linux_ktrsysret().

Start on a new library (libsysdecode) that provides routines for decoding system call information such as system call arguments. Initially this will consist of pulling duplicated code out of truss and kdump though it may prove useful for other utilities in the future. This commit moves the shared utrace(2) record parser out of kdump into the library and updates kdump and truss to use it. One difference from the previous version is that the library version treats unknown events that start with the "RTLD" signature as unknown events. This simplifies the interface and allows the consumer to decide how to handle all non-recognized events. Instead, this function only generates a string description for known malloc() and RTLD records. Reviewed by: bdrewery Differential Revision: https://reviews.freebsd.org/D4537

Properly format pointer size independent CloudABI system calls. CloudABI has approximately 50 system calls that do not depend on the pointer size of the system. As the ABI is pretty compact, it takes little effort to each truss(8) the formatting rules for these system calls. Start off by formatting pointer size independent system calls. Changes: - Make it possible to include the CloudABI system call definitions in FreeBSD userspace builds. Add ${root}/sys to the truss(8) Makefile so we can pull in <compat/cloudabi/cloudabi_syscalldefs.h>. - Refactoring: patch up amd64-cloudabi64.c to use the CLOUDABI_* constants instead of rolling our own table. - Add table entries for all of the system calls. - Add new generic formatting types (UInt, IntArray) that we'll be using to format unsigned integers and arrays of integers. - Add CloudABI specific formatting types.

To continue printing IDs in decimal, add a new QuadHex argument type that prints a 64-bit integer in hex, use QuadHex for the existing off_t arguments, repurpose Quad to print a 64-bit integer in decimal, and use Quad for id_t arguments.

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.

Rework the argv and env string fetching for execve to be more robust. Before truss would fetch 100 string pointers and happily walk off the end of the array if it never found a NULL. This also means for a short argv list it could fail entirely if the 100 string pointers spanned into an unmapped page. Instead, fetch page-aligned blocks of string pointers in a loop fetching each string until a NULL is found. While here, make use of the open memstream file descriptor instead of allocating a temporary array. This allows us to fetch each string once instead of twice.

The current POSIX semaphore implementation stores the _has_waiters flag in a separate word from the _count. This does not permit both items to be updated atomically in a portable manner. As a result, sem_post() must always perform a system call to safely clear _has_waiters. This change removes the _has_waiters field and instead uses the high bit of _count as the _has_waiters flag. A new umtx object type (_usem2) and two new umtx operations are added (SEM_WAIT2 and SEM_WAKE2) to implement these semantics. The older operations are still supported under the COMPAT_FREEBSD9/10 options. The POSIX semaphore API in libc has been updated to use the new implementation. Note that the new implementation is not compatible with the previous implementation. However, this only affects static binaries (which cannot be helped by symbol versioning). Binaries using a dynamic libc will continue to work fine. SEM_MAGIC has been bumped so that mismatched binaries will error rather than corrupting a shared semaphore. In addition, a padding field has been added to sem_t so that it remains the same size.

Add new mmap(2) flags to permit applications to request specific virtual address alignment of mappings. - MAP_ALIGNED(n) requests a mapping aligned on a boundary of (1 << n). Requests for n >= number of bits in a pointer or less than the size of a page fail with EINVAL. This matches the API provided by NetBSD. - MAP_ALIGNED_SUPER is a special case of MAP_ALIGNED. It can be used to optimize the chances of using large pages. By default it will align the mapping on a large page boundary (the system is free to choose any large page size to align to that seems best for the mapping request). However, if the object being mapped is already using large pages, then it will align the virtual mapping to match the existing large pages in the object instead. - Internally, VMFS_ALIGNED_SPACE is now renamed to VMFS_SUPER_SPACE, and VMFS_ALIGNED_SPACE(n) is repurposed for specifying a specific alignment. MAP_ALIGNED(n) maps to using VMFS_ALIGNED_SPACE(n), while MAP_ALIGNED_SUPER maps to VMFS_SUPER_SPACE. - mmap() of a device object now uses VMFS_OPTIMAL_SPACE rather than explicitly using VMFS_SUPER_SPACE. All device objects are forced to use a specific color on creation, so VMFS_OPTIMAL_SPACE is effectively equivalent. Reviewed by: alc MFC after: 1 month

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.

Fix handling of Quad-type arguments. Previously, syscalls containing 64-bit arguments would have explicit padding. On 64-bit platforms there was no padding, so the dummy argument was not covering anything. On 32-bit platforms with weak alignment (i.e. i386) the 64-bit argument did not need to be aligned, so there too an aditional argument was introduced. On 32-bit platforms with strong alignment (i.e. PowerPC) the dummy argument in fact cover the padding. By elimininating the dummy argument, 64-bit platforms now have 1 argument less. This also applies to 32-bit platforms with weak alignment. On PowerPC this doesn't matter, because the padding is still there. We just don't "name" it. Deal with those 3 cases.

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.

Fix Quad handling on 64-bit architectures. On 64-bit machines, a Quad also occupies a single slot. There's no need for any special handling of Quads. While here, remove the silly make_quad() function. We have the 2 longs on 32-bit machines already lined up in the argument array, so we can fetch the Quad with a simple cast. Before: lseek(1,0x123456789,0xd0d0d0d0d0d0d0d0) = 4886718345 (0x123456789) After: lseek(1,0x123456789,SEEK_SET) = 4886718345 (0x123456789)

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.

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.)

Do not ignore any possible errors that fseeko() may have. The fact is that fseeko() fails in very predictable and frequent ways on ia64. This is because the offset is actually an address in the process' address space, which on ia64 can be larger than long (for lseek) or off_t (for fseeko). The crux is the signedness. The register stack and memory stack are in region 4 on ia64. This means that the sign bit is 1. The large positive virtual address is wrongly interpreted as a negative file offset. There's no quick fix. Even if you get around the API by using a SEEK_SET up to LONG_MAX and follow it up with a SEEK_CUR for the remainder, the kernel simply cannot deal with it. and the second seek will just fail. Therefore, this change does not actually fix the root cause. It just makes sure we're not spitting out all kinds of garbage or that the get_struct() function in particular does not cause truss(1) to exit. This, I might add, invariably happened way too soon for truss(1) to be of any use on ia64...

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.
