* Avoid using vsnprintf(3) unless MALLOC_STATS is defined, in order tojasone2007-03-201-152/+233
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | avoid substantial potential bloat for static binaries that do not otherwise use any printf(3)-family functions. [1] Rearrange arena_run_t so that the region bitmask can be minimally sized according to constraints related to each bin's size class. Previously, the region bitmask was the same size for all run headers, which wasted a measurable amount of memory. Rather than making runs for small objects as large as possible, make runs as small as possible such that header overhead stays below a certain bound. There are two exceptions that override the header overhead bound: 1) If the bound is impossible to honor, it is relaxed on a per-size-class basis. Since there is one bit of header overhead per object (plus a constant), it is impossible to achieve a header overhead less than or equal to 1/(# of bits per object). For the current setting of maximum 0.5% header overhead, this relaxation comes into play for {2, 4, 8, 16}-byte objects, for which header overhead is (on 64-bit systems) {7.1, 4.3, 2.2, 1.2}%, respectively. 2) There is still a cap on small run size, still set to 64kB. This comes into play for {1024, 2048}-byte objects, for which header overhead is {1.6, 3.1}%, respectively. In practice, this reduces the run sizes, which makes worst case low-water memory usage due to fragmentation less bad. It also reduces worst case high-water run fragmentation due to non-full runs, but this is only a constant improvement (most important to small short-lived processes). Reduce the default chunk size from 2MB to 1MB. Benchmarks indicate that the external fragmentation reduction makes 1MB the new sweet spot (as small as possible without adversely affecting performance). Reported by: [1] kientzle

* - Sysctl's move to seperate filerrs2007-03-151-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | - moved away from ifn/ifa access to sctp_ifa/sctp_ifn built and managed by the add-ip code. - cleaned up add-ip code to use the iterator - made iterator be a thread, which enables auto-asconf now. - rewrote and cleaned up source address selection (also made it use new structures). - Fixed a couple of memory leaks. - DACK now settable as to how many packets to delay as well as time. - connectx() to latest socket API, new associd arg. - Fixed issue with revoking and loosing potential to send when we inflate the flight size. We now inflate the cwnd too and deflate it later when the revoked chunk is sent or acked. - Got rid of some temp debug code - src addr selection moved to a common file (sctp_output.c) - Support for simple VRF's (we have support for multi-vfr via compile switch that is scrubbed from BSD but we won't need multi-vrf until we first get VRF :-D) - Rest of mib work for address information now done - Limit number of addresses in INIT/INIT-ACK to a #def (30).

| | | | | | | | | | | | | behind _FREEFALL_CONFIG). This is done mainly to make NIS even more resistant to packet loss. This is not enabled by default for "normal" FreeBSD since it might cause the server providing the RPC service to be hit heavily with RPC traffic in case of problems. freefall.FreeBSD.org and hub.FreeBSD.org have been running with a patch similar to this for a couple of weeks.

* - Bump _yplib_timeout limit from 10 to 20 seconds to better handlesimon2007-03-041-1/+9
| | | | | | | | | | | | | | | | | | | | | | | packet loss when talking to a NIS server. - Set 1 second retry timeout to further realistically handle UDP packet loss for yp_next packet bursts. If the packet hasn't come back within 1 second its rather unlikely to come back at all. There is still back-off mechanism in RPC so if there is another reason than packet loss for the lack of response within 1 second, the NIS server will not be totally bombarded with requests. This reduces the risk of NIS failing with: yp_next: clnt_call: RPC: Timed out considerably. This is mainly a problem if you have larger NIS maps (like at FreeBSD.org) since enumerations of the lists will cause a UDP packet bursts where a few packets being lost once in a while do happen.

| | | | | | | | | | This is quite tricky situation, because we allow to open a file with O_RDONLY|O_TRUNC. O_TRUNC modifies a file, but we actually don't open it for writing. EISDIR is also returned when we try to open a directory O_RDONLY|O_TRUNC, which is correct. POSIX says that "The result of using O_TRUNC with O_RDONLY is undefined.", we choose to accept it (Solaris did the same), that's why "to be modified" seems more accurate to me.
