* Move mksubr from kdump into libsysdecode.John Baldwin2016-10-171-12/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Convert casperd(8) daemon to the libcasper.Mariusz Zaborski2016-02-251-2/+4
| | | | | | | | | | | | | | | | | | | | | | | After calling the cap_init(3) function Casper will fork from it's original process, using pdfork(2). Forking from a process has a lot of advantages: 1. We have the same cwd as the original process. 2. The same uid, gid and groups. 3. The same MAC labels. 4. The same descriptor table. 5. The same routing table. 6. The same umask. 7. The same cpuset(1). From now services are also in form of libraries. We also removed libcapsicum at all and converts existing program using Casper to new architecture.

* Add support to libsysdecode for decoding system call names.John Baldwin2016-01-261-19/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Move the mkioctls script to libsysdecode and use it to generate aJohn Baldwin2015-12-221-12/+2
| | | | | | | | | | | | | | sysdecode_ioctlname() function. This function matches the behavior of the truss variant in that it returns a pointer to a string description for known ioctls. The caller is responsible for displaying unknown ioctl requests. For kdump this meant moving the logic to handle unknown ioctl requests out of the generated function and into an ioctlname() function in kdump.c instead.

* Start on a new library (libsysdecode) that provides routines for decodingJohn Baldwin2015-12-151-2/+3
| | | | | | | | | | | | | | | | | | | | 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.

* Replace DPSRCS that work fine in SRCS.Bryan Drewery2015-11-251-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is so that 'make depend' is not a required build step in these files. DPSRCS is overall unneeded. DPSRCS already contains SRCS, so anything which can safely be in SRCS should be. DPSRCS is mostly just a way to generate files that should not be linked into the final PROG/LIB. For headers and grammars it is safe for them to be in SRCS since they will be excluded during linking and installation. The only remaining uses of DPSRCS are for generating .c or .o files that must be built before 'make depend' can run 'mkdep' on the SRCS c files list. A semi-proper example is in tests/sys/kern/acct/Makefile where a checked-in .c file has an #include on a generated .c file. The generated .c file should not be linked into the final PROG though since it is #include'd. The more proper way here is just to build/link it in though without DPSRCS. Another example is in sys/modules/linux/Makefile where a shell script runs to parse a DPSRCS .o file that should not be linked into the module. Beyond those, the need for DPSRCS is largely unneeded, redundant, and forces 'make depend' to be ran. Generally, these Makefiles should avoid the need for DPSRCS and define proper dependencies for their files as well. An example of an improper usage and why this matters is in usr.bin/netstat. nl_defs.h was only in DPSRCS and so was not generated during 'make all', but only during 'make depend'. The files including it lacked proper depenencies on it, which forced running 'make depend' to workaround that bug. The 'make depend' target should mostly be used for incremental build help, not to produce a working build. This specific example was broken in the meta build until r287905 since it does not run 'make depend'. The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS: SRCS:M*.h' when there is no .depend file.

* Normally, when a header file is removed from the build (as i4b headersDag-Erling Smørgrav2008-02-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | were recently), a simple 'make cleandepend; make depend' is sufficient to keep the tree buildable after a cvs update when doing incremental builds. However, kdump and truss use a script which searches for header files that define ioctls, and generates C code that includes them. This script will usually not need updating when a header file is removed, so the normal dependency mechanism will not realize that it needs to be re-run. One is therefore left with code that references dead files but will only be removed by a full 'make clean', which defeats the purpose of incremental builds. To work around this, modify the cleandepend target in bsd.dep.mk to also remove any files listed in a new variable named CLEANDEPFILES, and modify kdump's and truss's Makefiles accordingly.
