| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | panic when you attempt to remove the IP address. But it still fails to remove the address. MFC r265094 Add regression test for PR kern/189088. MFC r265092 Fix a panic when removing an IP address from an interface, if the same address exists on another interface. The panic was introduced by change 264887, which changed the fibnum parameter in the call to rtalloc1_fib() in ifa_switch_loopback_route() from RT_DEFAULT_FIB to RT_ALL_FIBS. The solution is to use the interface fib in that call. For the majority of users, that will be equivalent to the legacy behavior.

MFC r266860 Fix unintended KBI change from r264905. Add _fib versions of ifa_ifwithnet() and ifa_ifwithdstaddr() The legacy functions will call the _fib() versions with RT_ALL_FIBS, preserving legacy behavior. sys/net/if_var.h sys/net/if.c Add legacy-compatible functions as described above. Ensure legacy behavior when RT_ALL_FIBS is passed as fibnum. sys/netinet/in_pcb.c sys/netinet/ip_output.c sys/netinet/ip_options.c sys/net/route.c sys/net/rtsock.c sys/netinet6/nd6.c Call with _fib() functions if we must use a specific fib, or the legacy functions otherwise. tests/sys/netinet/fibs_test.sh tests/sys/netinet/udp_dontroute.c Improve the udp_dontroute test. The bug that this test exercises is that ifa_ifwithnet() will return the wrong address, if multiple interfaces have addresses on the same subnet but with different fibs. The previous version of the test only considered one possible failure mode: that ifa_ifwithnet_fib() might fail to find any suitable address at all. The new version also checks whether ifa_ifwithnet_fib() finds the correct address by checking where the ARP request goes. MFC r264917 Style fixes, mostly trailing whitespace elimination. No functional change. MFC r264905 Fix subnet and default routes on different FIBs on the same subnet. These two bugs are closely related. The root cause is that ifa_ifwithnet does not consider FIBs when searching for an interface address. sys/net/if_var.h sys/net/if.c Add a fib argument to ifa_ifwithnet and ifa_ifwithdstadddr. Those functions will only return an address whose interface fib equals the argument. sys/net/route.c Update calls to ifa_ifwithnet and ifa_ifwithdstaddr with fib arguments. sys/netinet/in.c Update in_addprefix to consider the interface fib when adding prefixes. This will prevent it from not adding a subnet route when one already exists on a different fib. sys/net/rtsock.c sys/netinet/in_pcb.c sys/netinet/ip_output.c sys/netinet/ip_options.c sys/netinet6/nd6.c Add RT_DEFAULT_FIB arguments to ifa_ifwithdstaddr and ifa_ifwithnet. In some cases it there wasn't a clear specific fib number to use. In others, I was unable to test those functions so I chose RT_DEFAULT_FIB to minimize divergence from current behavior. I will fix some of the latter changes along with PR kern/187553. tests/sys/netinet/fibs_test.sh tests/sys/netinet/udp_dontroute.c tests/sys/netinet/Makefile Revert r263738. The udp_dontroute test was right all along. However, bugs kern/187550 and kern/187553 cancelled each other out when it came to this test. Because of kern/187553, ifa_ifwithnet searched the default fib instead of the requested one, but because of kern/187550, there was an applicable subnet route on the default fib. The new test added in r263738 doesn't work right, however. I can verify with dtrace that ifa_ifwithnet returned the wrong address before I applied this commit, but route(8) miraculously found the correct interface to use anyway. I don't know how. Clear expected failure messages for kern/187550 and kern/187552. MFC r263738 tests/sys/netinet/Makefile tests/sys/netinet/fibs.sh Replace fibs:udp_dontroute with fibs:src_addr_selection_by_subnet. The original test was poorly written; it was actually testing kern/167947 instead of the desired kern/187553. The root cause of the bug is that ifa_ifwithnet did not have a fib argument. The new test more directly targets that behavior. tests/sys/netinet/udp_dontroute.c Delete the auxilliary binary used by the old test

| | | | | | | | | | | | | | | | | | | | | | Correct ARP update handling when the routes for network interfaces are restricted to a single FIB in a multifib system. Restricting an interface's routes to the FIB to which it is assigned (by setting net.add_addr_allfibs=0) causes ARP updates to fail with "arpresolve: can't allocate llinfo for x.x.x.x". This is due to the ARP update code hard coding it's lookup for existing routing entries to FIB 0. sys/netinet/in.c: When dealing with RTM_ADD (add route) requests for an interface, use the interface's assigned FIB instead of the default (FIB 0). sys/netinet/if_ether.c: In arpresolve(), enhance error message generated when an lla_lookup() fails so that the interface causing the error is visible in logs. tests/sys/netinet/fibs_test.sh Clear ATF expected error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Set up the /usr/tests hierarchy.jmmv2013-12-284-0/+130
This is a MFC of the following into stable/10: - r257097 Set up the /usr/tests hierarchy. - r257098 Add missing WITHOUTTESTS file. - r257100 Add a tests(7) manual page. - r257105 Disable WITHTESTS= for now. - r257848 Fix buildworld when WITHTESTS is enabled. - r257850 Subsume the functionality of MKATF into MKTESTS. - r257851 Handle the removal of the test suite when WITHOUTTESTS=yes. - r257852 Install category Kyuafiles from their category directories. - r258232 Install BSD.tests.mtree when MKTESTS is yes. Note that building with WITH_TESTS is still broken at this point (and hence why WITHOUT_TESTS is the set as the default). Subsequent pullups will fix the remaining issues.
