| | | | | | | | | | | | | | | used less than "stdio" -- include all the "self" operations. Instead of different defines, use regular PLEDGE_* in the "p_pledgenote" variable (which indicates the operation subtype a system call is performing). Many checks before easier to understand. p_pledgenote can often be passed directly to ktrace, so that kdump says: 15565 test CALL pledge(0xa9a3f804c51,0) 15565 test STRU pledge request="stdio" 15565 test RET pledge 0 15565 test CALL open(0xa9a3f804c57,0x2<O_RDWR>) 15565 test NAMI "/tmp/testfile" 15565 test PLDG open, "wpath", errno 1 Operation not permitted with help from semarie, ok guenther

Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

* Introduce ltrace(1). This tool works with ld.so to inject utrace record formiod2013-06-013-48/+243
| | | | | | | | | | | | | | | | | each plt call, allowing to trace a binary linked against shared library at the public function call level. To do so, ltrace(1) sets up some environment variables to enable plt tracing in ld.so, and invokes ktrace(2) for utrace events. ld.so will force lazy binding and will send an utrace record in the plt resolver, without updating the plt. Minimal filtering capabilities are provided, inspired by Solaris' truss -u, to limit tracing to libraries and/or symbol names. Non-traced libraries and symbols will have the regular resolver processing, with the expected plt update. "Get it in" deraadt
