* The origin_subst_one() function limits the length of the string tokib2013-04-151-73/+75
| | | | | | | | | | | | | | | | | | PATH_MAX after the token substitution. This is wrong, because origin_subst_one() performs the substitution on the whole rpath and similar strings, which contain several pathes separated by colon. As result, long (but correct) rpath consisting of many path elements is rejected by the function. Correct the problem by rewriting the origin_subst_one() to perform two passes, first pass to calculate the number of substitutions to be performed, and second pass to generate the resulting string. Second pass allocates the memory for the result based on the count from the first pass, without enforcing a limit. Reported and tested by: pgj Sponsored by: The FreeBSD Foundation MFC after: 2 weeks

New kernel is binary compatible with old tools, since sizes of sockaddr_inarp and sockaddr_in match, and sa_family are filled with same value. The structure declaration is left for compatibility with third party software, but in tree code no longer use it. Reviewed by: ru, andre, net@

* rtld: Fix fd leak with parallel dlopen and fork/exec.jilles2012-11-042-4/+4
| | | | | | | | | | | | | | | | Rtld did not set FD_CLOEXEC on its internal file descriptors; therefore, such a file descriptor may be passed to a process created by another thread running in parallel to dlopen() or fdlopen(). No other threads are expected to be running during parsing of the hints and libmap files but the file descriptors need not be passed to child processes so add O_CLOEXEC there as well. This change will break fdlopen() (as used by OpenPAM) on kernels without F_DUPFD_CLOEXEC (added in July). Note that running new userland on old kernels is not supported. Reviewed by: kib

Remove any files numbered higher than entropy_save_num. This helps when the user reduces the number, and may be useful for other purposes down the road. 4. Simplify the rotation logic by first testing the common case (it's a regular file) then testing if something else exists with the same name using elif. Also switch from using jot to simpler countdown format. 5. Fix logger lines and error messages to be more consistent, and wrap the code more consistently in the 80 column range. The "not a regular file" error message was mistakenly wrapped entirely in "quotes" which caused logger to include line-wrapping whitespace. Change that to wrap only the variables in quotes, which is both consistent and works better. 6. Update copyright to reflect the fact that changes were made this year.

Remove dead error handling code. Also use NULL for a nul-pointer instead of integer 0. While there, change all pieces of code that only use tv_sec to use time(3), as this provides less overhead.

The purpose of DT_RUNPATH is to have two different types of rpath: one that can be overridden by the environment variable LD_LIBRARY_PATH and one that can't. With the currently implementation, LD_LIBRARY_PATH will always trump any embedded rpath or runpath tags. Current path search order by rtld: ================================== LD_LIBRARY_PATH DT_RPATH / DT_RUNPATH (always the same) ldconfig hints file (default: /var/run/ld-elf.so.hints) /usr/lib New path search order by rtld: ============================== DT_RPATH of the calling object if no DT_RUNPATH DT_RPATH of the main binary if no DT_RUNPATH and binary isn't calling obj LD_LIBRARY_PATH DT_RUNPATH ldconfig hints file /usr/lib The new path search matches how the linux runtime loader works. The other major added feature is support for linker flag "-z nodefaultlib". When this flag is passed to the linker, rtld will skip all references to the standard library search path ("/usr/lib" in this case but it could handle more color delimited paths) except in DT_RPATH and DT_RUNPATH. New path search order by rtld with -z nodefaultlib flag set: ============================================================ DT_RPATH of the calling object if no DT_RUNPATH DT_RPATH of the main binary if no DT_RUNPATH and binary isn't calling obj LD_LIBRARY_PATH DT_RUNPATH ldconfig hints file (skips all references to /usr/lib) FreeBSD notes: - we fixed some bugs which were submitted to DragonFly and merged there as commit 1ff8a2bd3eb6e5587174c6a983303ea3a79e0002; - we added LD_LIBRARY_PATH_RPATH environment variable to switch to the previous behaviour of considering DT_RPATH a synonym for DT_RUNPATH; - the FreeBSD default search path is /lib:/usr/lib and not /usr/lib.

| | | | | | | | | | | | | | | | relocations are performed before the object's initializer is called. When dlopen()ing an object, relocate the whole DAG rooted in the object instead of only relocating the object itself and list of newly loaded dependencies. Reversed sequence currently can occur if the same object is a dependency for both filtee and filter, since filtees are loaded typically during the relocation processing, when some filter dependencies might be already loaded but not relocated yet.
