When a fast machine first brings up some non TCP networking program it is quite possible that we will drop packets due to the fact that only one packet can be held per ARP entry. This leads to packets being missed when a program starts or restarts if the ARP data is not currently in the ARP cache. This code adds a new sysctl, net.link.ether.inet.maxhold, which defines a system wide maximum number of packets to be held in each ARP entry. Up to maxhold packets are queued until an ARP reply is received or the ARP times out. The default setting is the old value of 1 which has been part of the BSD networking code since time immemorial. Expose the time we hold an incomplete ARP entry by adding the sysctl net.link.ether.inet.wait, which defaults to 20 seconds, the value used when the new ARP code was added..

$FreeBSD$ This directory is for regression test programs. A regression test program is one that will exercise a particular bit of the system to check that we have not reintroduced an old bug. Tests should be implemented in files with a .t extension. Each .t file can contain more than one test, and can be implemented in any scripting language -- /bin/sh, Perl... The test protocol is quite simple. At its most basic, each .t file should, when run, print a line in this format: 1..m where m is the number of tests that will be run. Each test should produce a single line of output. This line should start with one of ok n not ok n to indicate whether or not the test succeeded. 'n' is the test's number. Anything after this on the line (up to the first '#' if present) is considered to be the name of the test. Naming tests is optional, but encouraged. A test may be written which is conditional, and may need to be skipped. For example, the netatalk tests require 'options NETATALK' in the kernel. A test may be skipped by printing '# skip Reason for skipping' after the test name. For example, ok 1 - netatalk # skip 'options NETATALK' not compiled in A test may be flagged as 'todo'. This indicates that you expect the test to fail (perhaps because the necessary functionality hasn't been written yet). 'todo' tests are expected to fail, so when they start working the test framework can alert you to this happy occurence. Flag these tests with a '# TODO' comment after the test name not ok 1 - infiniteloop # TODO write test for an infinite loop This is modelled on the protocol followed by the Test::Harness Perl module (and therefore much of the automated testing carried out by the Perl community). More documentation can be found at: http://search.cpan.org/~petdance/Test-Harness-2.42/lib/Test/Harness.pm To run the tests and parse their output install the devel/p5-Test-Harness port. This includes the prove(1) command which is used to run the tests and collate the output. prove geom_concat # run all the tests in geom_concat prove -r lib # run all tests in lib/, and subdirectories prove -r -v lib # as above, with verbose output prove -r # run *all* the tests Tests that are for parts of the base system should go into a directory here which is the same as their path relative to src/, for example the uuencode(1) utility resides in src/usr.bin/uuencode so its regression test resides in src/tools/regression/usr.bin/uuencode. To avoid the pre-commit check program complaining about the lack of CVS keywords in test data files, use a .in suffix for input files and a .out suffix for output files. To execute individual regression tests for binaries that you are developing, add their directory in the path before running the tests. Example: cd /usr/src/tools/regression/usr.bin (PATH=/home/user/src/experimental/jot:$PATH ; make SUBDIR=jot) Please make a subdir per other regression test, and add a brief description to this file. acct Exercise the integer to float conversion used in acct(5) geom Some tests and an out-of-kernel simulator for the GEOM code ia64 ia64 specific regression tests nfsmmap Some tests to exercise some tricky cases in NFS and mmap p1003_1b Exercise 1003.1B scheduler pipe Pipe code regression test fsx General filesystem exerciser sysvmsg SysV IPC Message Queue Regression Utility sysvsem SysV IPC Semaphore Regression Utility sysvshm SysV IPC Shared Memory Regression Utility gaithrstress General threaded getaddrinfo(3) exerciser date Date(1) + format string regression test
