| | | | | | | | | | | This fixes truss when built as part of a riscv64sf world. Additionally, if FreeBSD ever supports RV32 RISC-V most of this file can be used as-is just as a single file is used for all of the MIPS ABIs. Sponsored by: DARPA Notes: svn path=/head/; revision=341656
* Allow truss to operate on ELFv2 processes.Justin Hibbits2018-11-291-0/+11
| | | | | | | | | | | | | | Summary: Currently, truss doesn't work on ELFv2 processes due to not recognizing the ABI. Since there's no special handling needed here, just adding a PROCABI struct for it is sufficient to get it working.

* Make timespecadd(3) and friends publicAlan Somers2018-07-303-23/+5
| | | | | | | | | | | | | | | | | | | | | | 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)Conrad Meyer2018-03-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

* Make truss work for CloudABI executables on i386.Ed Schouten2017-12-212-0/+99
| | | | | | | | | | | The system call convention is different from i386 binaries running on FreeBSD/amd64, but this is not noticeable by executables. On FreeBSD/amd64, the vDSO already does padding of arguments and return values to 64-bit values. On i386, it does not, meaning that system call return values are simply stored in registers.

As arguments are automatically padded to 64-bit words by the vDSO in userspace, we can copy the arguments directly into the array used by truss(8) internally.

* Decode kevent structures logged via ktrace(2) in kdump.John Baldwin2017-11-252-76/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.Ed Schouten2017-10-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.Ed Schouten2017-09-051-4/+3
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=323177

| | | | | | | | | | | | | | | | | | | 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.

* Upgrade to the latest sources generated from the CloudABI specification.Ed Schouten2017-07-261-15/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
