* MFC r270228:ngie2016-01-061-6/+47
| | | | | | | | | | | | | | | | | | | | | | | r270228 (by asomers): Numerous small fixes, mostly suggested by Coverity. tests/sys/kern/unix_seqpacket_test.c * Remove a duplicate error check in mk_pair_of_sockets * Always close sockets in the success path of ATF test cases. Don't bother with the error paths, because those are mostly assertions anyway. Most of these socket leaks were reported by Coverity. All of them are harmless, because each ATF test case runs in its own process. * Fix the len argument to send in shutdown_send and shutdown_send_sigpipe. The old version was using sizeof a pointer instead of sizeof the char array. Reported by Coverity. * Change a few ATF_CHECK to ATF_REQUIRE if the test can't reasonably continue past a failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Export current system call code and argument count for system call entry and exit events. To preserve the ABI, the new fields are moved to the end of struct thread in these branches (unlike HEAD) and explicitly copied when new threads are created. In addition, the new tests are only added in 10. r287386: Export current system call code and argument count for system call entry and exit events. procfs stop events for system call tracing report these values (argument count for system call entry and code for system call exit), but ptrace() does not provide this information. (Note that while the system call code can be determined in an ABI-specific manner during system call entry, it is not generally available during system call exit.) The values are exported via new fields at the end of struct ptrace_lwpinfo available via PT_LWPINFO. r288949: Fix various edge cases related to system call tracing. - Always set td_dbg_sc_* when P_TRACED is set on system call entry even if the debugger is not tracing system call entries. This ensures the fields are valid when reporting other stops that occur at system call boundaries such as for PT_FOLLOW_FORKS or when only tracing system call exits. - Set TDB_SCX when reporting the stop for a new child process in fork_return(). This causes the event to be reported as a system call exit. - Report a system call exit event in fork_return() for new threads in a traced process. - Copy td_dbg_sc_* to new threads instead of zeroing. This ensures that td_dbg_sc_code in particular will report the system call that created the new thread or process when it reports a system call exit event in fork_return(). - Add new ptrace tests to verify that new child processes and threads report system call exit events with a valid pl_syscall_code via PT_LWPINFO. r288993: Document the recently added pl_syscall_* fields in struct ptrace_lwpinfo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various fixes to orphan handling which also fix issues with following forks. 283281: Always set p_oppid when attaching to an existing process via procfs tracing. This matches the behavior of ptrace(PT_ATTACH). Also, the procfs detach request assumes p_oppid is always set. 283282: Only reparent a traced process to its old parent if the tracing process is not the old parent. Otherwise, proc_reap() will leave the zombie in place resulting in the process' status being returned twice to its parent. Add test cases for PT_TRACE_ME and PT_ATTACH which are fixed by this change. 283562: Do not allow a process to reap an orphan (a child currently being traced by another process such as a debugger). The parent process does need to check for matching orphan pids to avoid returning ECHILD if an orphan has exited, but it should not return the exited status for the child until after the debugger has detached from the orphan process either explicitly or implicitly via wait(). Add two tests for for this case: one where the debugger is the direct child (thus the parent has a non-empty children list) and one where the debugger is not a direct child (so the only "child" of the parent is the orphan). 283647: Tweak the description of when waitpid() doesn't return any status for a non-blocking wait to avoid the word "empty". 283836: Consistently only use one end of the pipe in the parent and debugger processes and do not rely on EOF due to a close() in the debugger. 284000: Add a CHILD_REQUIRE macro similar to ATF_REQUIRE for use in child processes of the main test process. 286158: Clear P_TRACED before reparenting a detached process back to its original parent. Otherwise the debugee will be set as an orphan of the debugger. Add tests for tracing forks via PT_FOLLOW_FORK.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace 4.4BSD Lite's unix domain socket backpressure hack with a cleaner mechanism, based on the new SB_STOP sockbuf flag. The old hack dynamically changed the sending sockbuf's high water mark whenever adding or removing data from the receiving sockbuf. It worked for stream sockets, but it never worked for SOCK_SEQPACKET sockets because of their atomic nature. If the sockbuf was partially full, it might return EMSGSIZE instead of blocking. The new solution is based on DragonFlyBSD's fix from commit 3a6117bbe0ed6a87605c1e43e12a1438d8844380 on 2008-05-27. It adds an SB_STOP flag to sockbufs. Whenever uipc_send surpasses the socket's size limit, it sets SB_STOP on the sending sockbuf. sbspace() will then return 0 for that sockbuf, causing sosend_generic and friends to block. uipc_rcvd will likewise clear SB_STOP. There are two fringe benefits: uipc_{send,rcvd} no longer need to call chgsbsize() on every send and receive because they don't change the sockbuf's high water mark. Also, uipc_sense no longer needs to acquire the UIPC linkage lock, because it's simpler to compute the st_blksizes. There is one drawback: since sbspace() will only ever return 0 or the maximum, sosend_generic will allow the sockbuf to exceed its nominal maximum size by at most one packet of size less than the max. I don't think that's a serious problem. In fact, I'm not even positive that FreeBSD guarantees a socket will always stay within its nominal size limit. sys/sys/sockbuf.h Add the SB_STOP flag and adjust sbspace() sys/sys/unpcb.h Delete the obsolete unp_cc and unp_mbcnt fields from struct unpcb. sys/kern/uipc_usrreq.c Adjust uipc_rcvd, uipc_send, and uipc_sense to use the SB_STOP backpressure mechanism. Removing obsolete unpcb fields from db_show_unpcb. tests/sys/kern/unix_seqpacket_test.c Clear expected failures from ATF.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix PR kern/185813 "SOCK_SEQPACKET AF_UNIX sockets with asymmetrical buffers drop packets". It was caused by a check for the space available in a sockbuf, but it was checking the wrong sockbuf. sys/sys/sockbuf.h sys/kern/uipc_sockbuf.c Add sbappendaddr_nospacecheck_locked(), which is just like sbappendaddr_locked but doesn't validate the receiving socket's space. Factor out common code into sbappendaddr_locked_internal(). We shouldn't simply make sbappendaddr_locked check the space and then call sbappendaddr_nospacecheck_locked, because that would cause the O(n) function m_length to be called twice. sys/kern/uipc_usrreq.c Use sbappendaddr_nospacecheck_locked for SOCK_SEQPACKET sockets, because the receiving sockbuf's size limit is irrelevant. tests/sys/kern/unix_seqpacket_test.c Now that 185813 is fixed, pipe_128k_8k fails intermittently due to 185812. Make it fail every time by adding a usleep after starting the writer thread and before starting the reader thread in test_pipe. That gives the writer time to fill up its send buffer. Also, clear the expected failure message due to 185813. It actually said "185812", but that was a typo. PR: kern/185813

r261081 Replace the old unix_seqpacket and unix_seqpacket_exercise tests, which were a little broken and not automatable, with unix_seqpacket_test. It's coverage is a superset of the old tests and it uses ATF. It includes test cases for bugs kern/185813 and kern/185812. r261133 Fix the Makefiles so that the tests I submitted in r261081 will actually get built. r261615 tests/sys/Makefile use TESTS_SUBDIRS for kern instead of SUBDIRS. I don't think it makes a difference in this case, but TESTS_SUBDIRS is generally correct for subdirectories that contain tests.
