caa449b6 - Use PT_GET_SC_ARGS and PT_GET_SC_RET in truss.

Tue, 16 Jul 2019 22:59:15 +0000

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 namesand FreeBSD errno values to ABI error values as well as hold syscallcounters. However, the linker set of ABI structures is now replacedwith a simple table mapping ABI names to structures. This approachpermits sharing the same ABI structure among separate names such asi386 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 theerror 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.Reviewed by: kibMFC after: 1 monthSponsored by: DARPADifferential Revision: https://reviews.freebsd.org/D20963 List of files: /freebsd-14.2/usr.bin/truss/Makefile

4be29fb3 - Make truss work for CloudABI executables on i386.

Thu, 21 Dec 2017 09:21:40 +0000

Make truss work for CloudABI executables on i386.The system call convention is different from i386 binaries running onFreeBSD/amd64, but this is not noticeable by executables. OnFreeBSD/amd64, the vDSO already does padding of arguments and returnvalues to 64-bit values. On i386, it does not, meaning that system callreturn values are simply stored in registers.

9289f547 - Move mksubr from kdump into libsysdecode.

Mon, 17 Oct 2016 22:37:07 +0000

Move mksubr from kdump into libsysdecode.Restructure this script so that it generates a header of tables insteadof a source file. The tables are included in a flags.c source file whichprovides functions to decode various system call arguments.For functions that decode an enumeration, the function returns a pointerto a string for known values and NULL for unknown values.For functions that do more complex decoding (typically of a bitmask), thefunction accepts a pointer to a FILE object (open_memstream() can be usedas a string builder) to which decoded values are written. If thefunction operates on a bitmask, the function returns true if any bitswere decoded or false if the entire value was valid. Additionally, thethird argument accepts a pointer to a value to which any undecoded bitsare stored. This pointer can be NULL if the caller doesn't care aboutremaining bits.Convert kdump over to using decoder functions from libsysdecode instead ofmksubr. truss also uses decoders from libsysdecode instead of privatelookup tables, though lookup tables for objects not decoded by kdump remainin truss for now. Eventually most of these tables should move intolibsysdecode as the automated table generation approach from mksubr isless 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 thesynopsis.Reviewed by: kib (several older versions), wblock (manpages)MFC after: 2 monthsDifferential Revision: https://reviews.freebsd.org/D7847 List of files: /freebsd-14.2/usr.bin/truss/Makefile

287b96dd - Add handling for non-native error values to libsysdecode.

Tue, 23 Feb 2016 20:00:55 +0000

Add handling for non-native error values to libsysdecode.Add two new functions, sysdecode_abi_to_freebsd_errno() andsysdecode_freebsd_to_abi_errno(), which convert errno values betweenthe native FreeBSD ABI and other supported ABIs. Note that themappings are not necessarily perfect meaning in some cases multipleerrors in one ABI might map to a single error in another ABI. In thatcase, the reverse mapping will return one of the errors that maps, butwhich error is non-deterministic.Change truss to always report the raw error value to the user butuse libsysdecode to map it to a native errno value that can be usedwith strerror() to generate a description. Previously truss reportedthe "converted" error value. Now the user will always see the exacterror value that the application sees.Change kdump to report the truly raw error value to the user. Previouslykdump would report the absolute value of the raw error value (so forLinux binaries it didn't output the FreeBSD error value, but the positivevalue of the Linux error). Now it reports the real (i.e. negative) errorvalue for Linux binaries. Also, use libsysdecode to convert the nativeFreeBSD error reported in the ktrace record to the raw error used by theABI. This means that the Linux ABI can now be handled directly inktrsysret() and removes the need for linux_ktrsysret().Reviewed by: bdrewery, kibHelpful notes: wblock (manpage)Differential Revision: https://reviews.freebsd.org/D5314 List of files: /freebsd-14.2/usr.bin/truss/Makefile

a5f14abf - Add support to libsysdecode for decoding system call names.

Tue, 26 Jan 2016 19:07:09 +0000

Add support to libsysdecode for decoding system call names.A new sysdecode_syscallname() function accepts a system call code andreturns a string of the corresponding name (or NULL if the code isunknown). To support different process ABIs, the new function accepts avalue from a new sysdecode_abi enum as its first argument to select theABI in use. Current ABIs supported include FREEBSD (native binaries),FREEBSD32, LINUX, LINUX32, and CLOUDABI64. Note that not all ABIs aresupported by all platforms. In general, a given ABI is only supportedif a platform can execute binaries for that ABI.To simplify the implementation, libsysdecode's build reuses theexisting pre-generated files from the kernel source tree rather thanduplicating new copies of said files during the build.kdump(1) and truss(1) now use these functions to map system callidentifiers to names. For kdump(1), a new 'syscallname()' functionconsolidates duplicated code from ktrsyscall() and ktrsyscallret().The Linux ABI no longer requires custom handling for ktrsyscall() andlinux_ktrsyscall() has been removed as a result.Reviewed by: bdreweryDifferential Revision: https://reviews.freebsd.org/D4823 List of files: /freebsd-14.2/usr.bin/truss/Makefile

Tue, 22 Dec 2015 20:33:49 +0000

Move the mkioctls script to libsysdecode and use it to generate asysdecode_ioctlname() function. This function matches the behaviorof the truss variant in that it returns a pointer to a string descriptionfor known ioctls. The caller is responsible for displaying unknownioctl requests. For kdump this meant moving the logic to handle unknownioctl requests out of the generated function and into an ioctlname()function in kdump.c instead.Differential Revision: https://reviews.freebsd.org/D4610 List of files: /freebsd-14.2/usr.bin/truss/Makefile

d6fb4894 - Start on a new library (libsysdecode) that provides routines for decoding

Tue, 15 Dec 2015 00:05:07 +0000

Start on a new library (libsysdecode) that provides routines for decodingsystem call information such as system call arguments. Initially thiswill consist of pulling duplicated code out of truss and kdump though itmay prove useful for other utilities in the future.This commit moves the shared utrace(2) record parser out of kdump intothe library and updates kdump and truss to use it. One difference fromthe previous version is that the library version treats unknown eventsthat start with the "RTLD" signature as unknown events. This simplifiesthe interface and allows the consumer to decide how to handle allnon-recognized events. Instead, this function only generates a stringdescription for known malloc() and RTLD records.Reviewed by: bdreweryDifferential Revision: https://reviews.freebsd.org/D4537 List of files: /freebsd-14.2/usr.bin/truss/Makefile

8c444cbc - Simplify syscall generation and ABI source file handling for the build.

Tue, 13 Oct 2015 18:23:51 +0000

Simplify syscall generation and ABI source file handling for the build.This is to make the Makefile more easily extendable for new ABIs.This also makes several other subtle changes: - The build now is given a list of ABIs to use based on the MACHINE_ARCH or MACHINE_CPUARCH. These ABIs have a related path in sys/ that is used to generate their syscalls. For each ABI to build check for a ABI.c, MACHINE_ARCH-ABI.c, or a MACHINE_CPUARCH-ABI.c. This matches the old behavior needed for archs such as powerpc* and mips*. - The ABI source file selection allows for simpler assignment of common ABIs such as "fbsd32" from sys/compat/freebsd32, or cloudabi64. - Expand 'fbsd' to 'freebsd' everywhere for consistency. - Split out the powerpc-fbsd.c file into a powerpc64-freebsd32.c to be more like the amd64-freebsd32.c file and to more easily allow the auto-generation of ABI handling to work. - Rename 'syscalls.h' to 'fbsd_syscalls.h' to lessen the ambiguity and avoid confusion with syscall.h (such as in r288997). - For non-native syscall header files, they are now renamed to be ABI_syscalls.h, where ABI is what ABI the Makefile is building. - Remove all of the makesyscalls config files. The "native" one being name i386.conf was a long outstanding bug. They were all the same except for the data they generated, so now it is just auto-generated as a build artifact. - The syscalls array is now fixed to be static in the syscalls header to remove the compiler warning about non-extern. This was worked around in the aarch64-fbsd.c file but not the others. - All syscall table names are now just 'syscallnames' since they don't need to be different as they are all static in their own ABI files. The alternative is to name them ABI_syscallnames which does not seem necessary.Reviewed by: ed, jhbMFC after: 3 weeksDifferential Revision: https://reviews.freebsd.org/D3851 List of files: /freebsd-14.2/usr.bin/truss/Makefile
