| | | | | | | | | | | | userland via routing socket or sysctl. This eliminates the following KAME-specific sin6_scope_id handling routine from each userland utility: sin6.sin6_scope_id = ntohs(*(u_int16_t *)&sin6.sin6_addr.s6_addr[2]); This behavior can be controlled by net.inet6.ip6.deembed_scopeid. This is set to 1 by default (sin6_scope_id will be filled in the kernel). Reviewed by: bz
* Show the number of times we block waiting for mbufs.alfred2012-10-251-4/+18
| | | | | | | | | | | | | | | | | | Machines can stall out because mbufs are low, however sometimes we won't see "requests denied", instead we see user land processes or kernel threads blocking waiting for mbufs because they set M_WAIT. These consumers do not see errors, only stalling. Unfortunately until now, netstat did not export this information so you could have experienced an mbuf shortage and have no way of seeing it unless you happen to run netstat at the exact time of the shortage and see "in use" = "max". By exporting the number of times processes are blocked, we can effectively see how often non-interrupt context threads are effectively "denied". MFC after: 2 weeks

* Merge the projects/pf/head branch, that was worked on for last six months,glebius2012-09-081-5/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Note the remark "Work around a clang false positive with format string warnings and ntohs macros (see LLVM PR 11313)" was actually incorrect. Before r232745, on some arches, the ntohs() macros did in fact return int, not uint16_t, so clang was right in warning about the %hu format string. MFC after: 2 weeks

| | | | | | | | | | The index() and rindex() functions were marked LEGACY in the 2001 revision of POSIX and were subsequently removed from the 2008 revision. The strchr() and strrchr() functions are part of the C standard. This makes the source code a lot more consistent, as most of these C files also call into other str*() routines. In fact, about a dozen already perform strchr() calls.
