| | | | | | | | | | | | | | | atomic(9) primitives are documented as operating on unsigned types. Here, we need a cast to avoid a tautological comparison.

* netbsd-tests: Remove some pointless sleeps from message queue testsMark Johnston2023-03-103-6/+0
| | | | | | | | | | - In the msgctl tests, there is no point in sleeping after a fork(). Just block immediately in wait(). - In non-blocking send/recv tests, just wait for the child to exit once it's reached a message limit. If a bug prevents the child from exiting promptly, the test will time out. MFC after: 1 week

* t_setrlimit: Adjust resource limit to 20MDawid Gorecki2021-12-201-0/+4
| | | | | | | | | | | | | With ASLR enabled by default, RLIMIT_STACK test fails due to the fact that default stack gap can be as big as 15M. Because of that the resource limit of 4M results in test program receiving SIGSEGV immediately after exiting the setrlimit syscall. Since the idea of this test is to check if rlim_cur does not extend past rlim_max, adjusting the resource limit to 20M should not invalidate the test results.

* Fix two failing tests after ATF updateAlex Richardson2021-02-152-6/+23
| | | | | | | | | | | | | | | | | | | | | Since https://github.com/freebsd/atf/commit/4581cefc1e3811dd3c926b5dd4b15fd63d2e19da ATF opens the results file on startup. This fixes problems like capsicumized tests not being able to open the file on exit. However, this test closes all file descriptors just to check that socketpair returns fd 3+4 and thereby also closes the ATF results file. This then results in an EBADF when writing the result so the test is reported as broken. While system calls that create new file descriptors (must?) use the lowest available file descriptor number, it does not seem useful to test this property here. Drop the check for FD==3/4 to unbreak the testsuite. We could also try to re-open the results file in ATF if we get a EBADF error, but that will fail when running under Capsicum.

* Provide separate accounting for user-wired pages.Mark Johnston2019-05-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically we have not distinguished between kernel wirings and user wirings for accounting purposes. User wirings (via mlock(2)) were subject to a global limit on the number of wired pages, so if large swaths of physical memory were wired by the kernel, as happens with the ZFS ARC among other things, the limit could be exceeded, causing user wirings to fail. The change adds a new counter, v_user_wire_count, which counts the number of virtual pages wired by user processes via mlock(2) and mlockall(2). Only user-wired pages are subject to the system-wide limit which helps provide some safety against deadlocks. In particular, while sources of kernel wirings typically support some backpressure mechanism, there is no way to reclaim user-wired pages shorting of killing the wiring process. The limit is exported as vm.max_user_wired, renamed from vm.max_wired, and changed from u_int to u_long. The choice to count virtual user-wired pages rather than physical pages was done for simplicity. There are mechanisms that can cause user-wired mappings to be destroyed while maintaining a wiring of the backing physical page; these make it difficult to accurately track user wirings at the physical page layer. The change also closes some holes which allowed user wirings to succeed even when they would cause the system limit to be exceeded. For instance, mmap() may now fail with ENOMEM in a process that has called mlockall(MCL_FUTURE) if the new mapping would cause the user wiring limit to be exceeded. Note that bhyve -S is subject to the user wiring limit, which defaults to 1/3 of physical RAM. Users that wish to exceed the limit must tune vm.max_user_wired.

* nanosleep(2): Fix bogus incrementing of rmtp by tc_tick_sbt on [EINTR].Bryan Drewery2018-02-141-0/+81
| | | | | | | | | | | | | | | | | | | | | sbt is the time in the future that the tsleep_sbt() is expected to be completed at. sbtt is the current time. Depending on the precision with sysctl kern.timecounter.alloweddeviation the start time may be incremented by tc_tick_sbt. The same increment is needed for the current time of sbtt before calculating the difference. The impact of missing this increment is that rmtp may increase by one tc_tick_sbt on every early [EINTR] return. If the same struct is passed in for rqtp as rmtp this can result in rqtp effectively incrementing by tc_tick_sbt and sleeping longer than originally intended. This problem was introduced in r247797.

| | | | | | | | | | | | | | | | | | | | | | | | Add a clock_nanosleep() syscall, as specified by POSIX. Make nanosleep() a wrapper around it. Attach the clock_nanosleep test from NetBSD. Adjust it for the FreeBSD behavior of updating rmtp only when interrupted by a signal. I believe this to be POSIX-compliant, since POSIX mentions the rmtp parameter only in the paragraph about EINTR. This is also what Linux does. (NetBSD updates rmtp unconditionally.) Copy the whole nanosleep.2 man page from NetBSD because it is complete and closely resembles the POSIX description. Edit, polish, and reword it a bit, being sure to keep any relevant text from the FreeBSD page.
