When executing an \s-1ELF\s0 binary +that links against libraries, the PaX hardened kernel ignores the library +markings and uses the executable markings for enforcing PaX restrictions. +It is desireable in some circumstances to migrate back the library markings +to the binaries. +.PP +revdep-pax can do its work by either starting from the object and mapping +forwards to its libraries, or by starting from a library and mapping +backwards to all the objects that link against it. The library can either +be specified by the \s-1SONAME\s0 as it is reported by \fBldd\fR(1), or by the full +path to the \s-1LIBRARY\s0 file. Symbolic links are dereferenced. The user can +optionally scan for all forward mappings on the system (\-f), for all reverse +mappings (\-r), for forward mappings of just one \s-1OBJECT\s0 (\-b), for reverse +mappings of just one \s-1SONAME\s0 (\-s) or one \s-1LIBRARY\s0 (\-l). In verbose mode (\-v), +all mappings are reported, not just mismatching ones, and in mark mode (\-m), +the user is prompted whether to proceed with marking the found object so +its PaX flags match its source. +.SH "OPTIONS" +.IX Header "OPTIONS" +.IP "\fB\-f\fR Scan the system for all forward mappings" 4 +.IX Item "-f Scan the system for all forward mappings" +.PD 0 +.IP "" 4 +.IP "\fB\-r\fR Scan the system for all reverse mappings" 4 +.IX Item "-r Scan the system for all reverse mappings" +.IP "" 4 +.IP "\fB\-b\fR \s-1OBJECT\s0 Retrieve only the forward mappings for this \s-1ELF\s0 \s-1OBJECT\s0" 4 +.IX Item "-b OBJECT Retrieve only the forward mappings for this ELF OBJECT" +.IP "" 4 +.IP "\fB\-s\fR \s-1SONAME\s0 Retrieve only the reverse mappings for this \s-1SONAME\s0" 4 +.IX Item "-s SONAME Retrieve only the reverse mappings for this SONAME" +.IP "" 4 +.IP "\fB\-l\fR \s-1LIBRARY\s0 Retrieve only the reverse mappings for this \s-1LIBRARY\s0" 4 +.IX Item "-l LIBRARY Retrieve only the reverse mappings for this LIBRARY" +.IP "" 4 +.IP "\fB\-v\fR Report all mappings, not just the mismatched ones" 4 +.IX Item "-v Report all mappings, not just the mismatched ones" +.IP "" 4 +.IP "\fB\-m\fR Prompt the user to mark the found object with the PaX flags of the source" 4 +.IX Item "-m Prompt the user to mark the found object with the PaX flags of the source" +.IP "" 4 +.IP "\fB\-h\fR Print out a short help message and exit." 4 +.IX Item "-h Print out a short help message and exit." +.PD +.SH "HOMEPAGE" +.IX Header "HOMEPAGE" +http://dev.gentoo.org/~blueness/elfix +.SH "REPORTING BUGS" +.IX Header "REPORTING BUGS" +Please report bugs at http://bugs.gentoo.org. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fBscanelf\fR(1), \fBdumpelf\fR(1), \fBpaxctl\fR(1), \fBpspax\fR(1), \fBfix-gnustack\fR(1), \fBldd\fR(1) +.SH "AUTHORS" +.IX Header "AUTHORS" +\&\fBAnthony G.
