'Fix' for esoteric misfeature discovered while searching for another bug:

1995-04-04T05:53:22Z

select() returns EINVAL if you try to feed it a value of FD_SETSIZE greater that 256. You can apparently adjust this by specifying a larger value of FD_SETSIZE when configuring your kernel. However, if you set the maximum number of open file descriptors per process to some value greater than the FD_SETSIZE value that select() expects, many selects() within the RPC library code will be botched because _rpc_dtablesize() will return invalid numbers. This is to say that it will return the upper descriptor table size limit which can be much higher than 256. Unless select() is prepared to expect this 'unusually' high value, it will fail. (A good example of this can be seen with NIS enabled: if you type 'unlimit' at the shell prompt and then run any command that does NIS calls, you'll be bombarded with errors from clnttcp_create().) A temporary fix for this is to clamp the value returned by _rpc_dtablesize() at FD_SETSIZE (as defined in (256)). I suppose the Right Thing would be to provide some mechanism for select() to dynamically adjust itself to handle FD_SETSIZE values larger than 256, but it's a bit late in the game for that. Hopefully 256 file descriptors will be enough to keep RPC happy for now.

Obtained from: Casper H. Dik (by vay of Usenet) Small patch to help improve NIS rebinding times (among other things): >From: casper@fwi.uva.nl (Casper H.S. Dik) >Newsgroups: comp.sys.sun.misc,comp.sys.sun.admin >Subject: FIX for slow rebinding of NIS. >Summary: a small change in libc makes life with NIS a lot easier. >Message-ID: <1992Jan17.173905.11727@fwi.uva.nl> >Date: 17 Jan 92 17:39:05 GMT >Sender: news@fwi.uva.nl >Organization: FWI, University of Amsterdam >Lines: 138 >Nntp-Posting-Host: halo.fwi.uva.nl Have you been plagued by long waits when your NIS server is rebooted? READ ON! Sun has a patch, but the README says: ********************* WARNING ****************************** This is a new version of ypbind that never uses the NIS binding file to cache the servers binding. This will have the effect of fixing the current symptom. However, it might degrade the overall performance of the system when the server is available. This is most likely to happen on an overloaded server, which will cause the network to produce a broadcast storm. ************************************************************* Therefor, I have produced another fix. o What goes wrong. When the NIS server is rebooted, ypserv will obtain different ports to listen for RPC requests. All clients will continue to use the old binding they obtained earlier. The NIS server will send ICMP dst unreachable messages for the RPC requests that arrive at the old port. These ICMPs are dropped on the floor and the client code will continue sending the requests until the timer has expired. The small fix at the end of this message will pick up these ICMP messages and deliver them to the RPC layer. o Before and after. I've tested this on some machines and this is the result: (kill and restart ypserv on the server) original% time ypmatch user passwd user:.... 0.040u 0.090s 2:35.64 0.0% 0+126k 0+0io 0pf+0w (155 seconds elapsed time) fixedhost% time ypmatch user passwd user:.... 0.050u 0.050s 0:10.20 0.9% 0+136k 0+0io 0pf+0w (10 seconds elapsed time) Rebinding is almost instantaneous. o Other benefits. RPC calls that use UDP as transport will no longer time out but will abort much sooner. (E.g., the remote host is unreachable or 111/udp is filtered by an intermediate router)
