http://seclists.org/nmap-dev/2012/q3/56. r29134 already addressed the issue but
was incomplete.
This replaces r29134 with an engine-agnostic approach, and additionally enforces
the reset of IOD flags before use or re-use.
- Always format function name without parens at the beginning of a message.
- Added a nsi_new notification message.
- Only trace the first call to nsi_delete() of a given IOD (i.e. don't log the
calls issued from the resulting callbacks).
support for system-specific scalable IO notification facilities without breaking
portability. This initial version comes with an epoll(7)-based engine for Linux
and a select(2)-based fallback engine for all other operating systems.
This required an important refactoring of the library but the external API was
preserved.
The rewrite also tries to bring the coding standards of nmap to nsock.
See http://labs.unix-junkies.org/nsock_engines.html for the details.
If you have trouble updating after this revision you need to follow
these instructions. You have probably just seen an error like this:
svn: URL 'svn://svn.insecure.org/nping' of existing directory 'nping'
does not match expected URL 'svn://svn.insecure.org/nmap/nping'
This is caused by the replacement of SVN externals.
Here's what you need to do. First, save any local changes you might have
in the nping, nsock, nbase, ncat, and zenmap directories. (For example
by running "cd nping; svn diff > ../nping.diff".) If you don't have any
local changes you can skip this step.
Then run these commands:
rm -rf nping/ nsock/ nbase/ ncat/ zenmap/
svn update
svn cleanup
If all else fails, you can just delete your whole working directory and
check out anew:
svn co --username guest --password "" svn://svn.insecure.org/nmap
