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.

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().

Alpha support for truss. I tested this on both bento and beast (thanks, Jordan, for pointing me at beast!). There should be no change for the i386 version. 1998-10-03 00:43:05 +00:00
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.

truss: Add support for utrace(2). This uses the kdump(1) utrace support code directly until a common library is created. This allows malloc(3) tracing with MALLOC_CONF=utrace:true and rtld tracing with LD_UTRACE=1. Unknown utrace(2) data is just printed as hex.

First cut at printing out ioctl names intelligently. Note that this doesn't handle linux ioctls (yet?). This uses the mkioctl script from kdump, bless its little heart. Reviewed by: Mike Smith 1997-12-06 06:51:14 +00:00
