| | | | | | | | | | | Only filter out the PF ioctls if we're building without pf support. Until now those were always filtered out, so truss did not show symbolic names for pf ioctls. Differential Revision: https://reviews.freebsd.org/D11629 Notes: svn path=/head/; revision=321370
* Remove special handling for 'disk*.h'John Baldwin2017-07-181-3/+1
| | | | | | | | | | | This was originally added so that only one of diskmbr.h or diskpc98.h was chosen and is no longer needed after PC98's removal. However, the special handling was also broken as it effectively prevented the decoding of ioctls declared in other headers such as <sys/disk.h> or <sys/disklabel.h>.

| | | | | | | | | | | | | | | This also avoids an error from egrep when a header is missing. This can happen with something like WITHOUT_BLUETOOTH set when searching for $include_dir/netgraph/bluetooth/include/ng_btsocket.h. The warning was not an error (from set -e) due to being on the left side of a pipe. Now the all_headers list is only filled with existing headers.

* Improve decoding of RB_AUTOBOOT in the 'howto' argument to reboot().John Baldwin2017-06-101-1/+12
| | | | | | | | | | | | The reboot() system call accepts a mode (RB_AUTOBOOT, RB_HALT, RB_POWEROFF, or RB_REROOT) as well as zero or more optional flags in 'howto'. However, RB_AUTOBOOT was only displayed if 'howto' was exactly 0. Combinations like 'RB_AUTOBOOT | RB_DUMP' were decoded as 'RB_DUMP'. Instead, imply that RB_AUTOBOOT was specified if none of the other "mode" flags were specified. Notes: svn path=/head/; revision=319765

* Move mksubr from kdump into libsysdecode.John Baldwin2016-10-1721-10/+2316
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=297247

| * Add handling for non-native error values to libsysdecode.John Baldwin2016-02-236-3/+312
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* Add support to libsysdecode for decoding system call names.John Baldwin2016-01-265-2/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | A new sysdecode_syscallname() function accepts a system call code and returns a string of the corresponding name (or NULL if the code is unknown). To support different process ABIs, the new function accepts a value from a new sysdecode_abi enum as its first argument to select the ABI in use. Current ABIs supported include FREEBSD (native binaries), FREEBSD32, LINUX, LINUX32, and CLOUDABI64. Note that not all ABIs are supported by all platforms. In general, a given ABI is only supported if a platform can execute binaries for that ABI. To simplify the implementation, libsysdecode's build reuses the existing pre-generated files from the kernel source tree rather than duplicating new copies of said files during the build. kdump(1) and truss(1) now use these functions to map system call identifiers to names. For kdump(1), a new 'syscallname()' function consolidates duplicated code from ktrsyscall() and ktrsyscallret(). The Linux ABI no longer requires custom handling for ktrsyscall() and linux_ktrsyscall() has been removed as a result.

The caller is responsible for displaying unknown ioctl requests.

* Start on a new library (libsysdecode) that provides routines for decodingJohn Baldwin2015-12-155-0/+344
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.
