* | Close a race with caching of -ve name lookups in the NFS client.John Baldwin2009-10-161-6/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specifically, clients only trust -ve cache entries while the directory remains unchanged and discard any -ve cache entries for a directory when they notice that the modification time of a directory entry changes. The race involves two concurrent lookups as follows: - Thread A does a lookup for file 'foo' which sends a lookup RPC to the server. The lookup fails and the server replies. - The 'foo' file is created (either by the same client or a different client) updating the modification time on the parent directory of 'foo'. - Thread B does a lookup for a different file 'bar' which updates the cached attributes of the parent directory of 'foo' to reflect the new modification time after 'foo' was created. - Thread A finally resumes execution to parse the reply from the NFS server. It adds a -ve cache entry and sets the cached value of the directory's modification time that is used for invalidating -ve cached lookups to the new modification time set by thread B. At this point, future lookups of 'foo' will honor the -ve cached entry until the cached entry is pushed out of the name cache's LRU or the modification time of the parent directory is changed again by some other change. The fix is to read the directory's modification time before sending the lookup RPC and use that cached modification time when setting the directory's cached modification time. Also, we do not add a -ve cache entry if another thread has added -ve cache entry that set the directory's cached modification time to a newer value than the value we read before sending the lookup RPC.

I plan to add a similar extension to sweep on a range of IP addresses, so we can issue a single command to flood (obviously, for testing purposes!) a number of different destinations. When there is only one destination, we do a preliminary connect() of the socket so we can use send() instead of sendto(). When we have multiple ports, the socket is not connect()'ed and we do a sendto() instead. There is a performance hit in this case, as the throughput on the loopback interface (with a firewall rule that blocks the transmission) goes down from 900kpps to 490kpps on my test machine. If the number of different destinations is limited, one option to explore is to have multiple connect()ed sockets. MFC after: 1 month Notes: svn path=/head/; revision=198136

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | handlers. This is primarily intended as a way to allow devices that use multiple interrupts (e.g. MSI) to meaningfully distinguish the various interrupt handlers. - Add a new BUS_DESCRIBE_INTR() method to the bus interface to associate a description with an active interrupt handler setup by BUS_SETUP_INTR. It has a default method (bus_generic_describe_intr()) which simply passes the request up to the parent device. - Add a bus_describe_intr() wrapper around BUS_DESCRIBE_INTR() that supports printf(9) style formatting using var args. - Reserve MAXCOMLEN bytes in the intr_handler structure to hold the name of an interrupt handler and copy the name passed to intr_event_add_handler() into that buffer instead of just saving the pointer to the name. - Add a new intr_event_describe_handler() which appends a description string to an interrupt handler's name. - Implement support for interrupt descriptions on amd64 and i386 by having the nexus(4) driver supply a custom bus_describe_intr method that invokes a new intr_describe() MD routine which in turn looks up the associated interrupt event and invokes intr_event_describe_handler().

* | A small change to avoid calling gettimeofday() too oftenLuigi Rizzo2009-10-151-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (hardwired to once every 20us at most). I found out that on many machines round here, i could only get 300-400kpps with netsend even on loopback and a 'deny' rule in the firewall, while reducing the number of calls to gettimeofday() brings the value to 900kpps and more. This code is just a quick fix for the problem. Of course it could be done better, with proper getopt() parsing and the like, but since this applies to the entire program i'll postpone that to when i have more time.

The incomplete ARP entry was timing out too quickly (1 second timeout), as such, a new entry is created each time arpresolve() is called. Therefore the maximum attempts made is always 1. Consequently the error code returned to the application is always 0. 2. Set the expiration of each incomplete entry to a 20-second lifetime. 3. Return "incomplete" entries to the application.
