* Various fixes for floating point on RISC-V.John Baldwin2018-09-194-3/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Explicitly load an empty initial state into FP registers when taking the fault on the first FP instruction in a thread. Setting SSTATE.FS to INITIAL is just a marker to let context switch restore code know that it can load FP registers with zeroes instead of memory loads. It does not imply that the hardware will reset all registers to zero on first access. In addition, set the state to CLEAN instead of INITIAL after the first FP instruction. cpu_switch() doesn't do anything for INITIAL and only restores from the pcb if the state is CLEAN. We could perhaps change cpu_switch to call fpe_state_clear if the state was INITIAL and leave SSTATE.FS set to INITIAL instead of CLEAN after the first FP instruction. However, adding this complexity to cpu_switch() doesn't seem worth the supposed gain. - Only save the current FPU registers in fill_fpregs() if the request is made to save the current thread's registers. Previously if a debugger requested FP registers via ptrace() it was getting a copy of the debugger's FP registers rather than the debugee's. - Zero the entire FP register set structure returned for ptrace() if a thread hasn't used FP registers rather than leaking garbage in the fp_fcsr field. - If a debugger writes FP registers via ptrace(), always mark the pcb as having valid FP registers and set SSTATUS.FS_MASK to CLEAN so that the registers will be restored when the debugged thread resumes. - Be more explicit about clearing the SSTATUS.FS field before setting it to CLEAN on the first FP instruction trap.

| | | | | | | | | | | | | | | | | | | | | | | | | | | route cache updates. Bring over locking changes applied to udp_output() for the route cache in r297225 and fixed in r306559 which achieve multiple things: (1) acquire an exclusive inp lock earlier depending on the expected conditions; we add a comment explaining this in udp6, (2) having acquired the exclusive lock earlier eliminates a slight possible chance for a race condition which was present in v4 for multiple years as well and is now gone, and (3) only pass the inp_route6 to ip6_output() if we are holding an exclusive inp lock, so that possible route cache updates in case of routing table generation number changes can happen safely. In addition this change (as the legacy IP counterpart) decomposes the tracking of inp and pcbinfo lock and adds extra assertions, that the two together are acquired correctly.

* vm: check for empty kstack cache before lockingMateusz Guzik2018-09-191-1/+1
| | | | | | | | | | | | | | | | | | The current cache logic checks the total number of stacks in the kernel, which even on small boxes significantly exceeds the 128 limit (e.g. an 8-way box with zfs has almost 800 stacks allocated). Stacks are cached earlier for each main thread. As a result the code is rarely executed, but when it is then (on boxes like the above) it always fails. Since there are no provisions made for NUMA and release time is approaching, just do a quick check to avoid acquiring the lock. Approved by: re (kib) Notes: svn path=/head/; revision=338802

* Fix state of dquot-less vnodes after failed quotaoff.Konstantin Belousov2018-09-193-7/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UFS quotaoff iterates over all mp vnodes, and derefences and clears the pointers to corresponding dquots. If SU work items transiently reference some of dquots,quotaoff() would eventually fail, but all processed vnodes are already stripped from dquots. The state is problematic, since quotas are left enabled, but there is no dquots where blocks and inodes can be accounted. The result is assertion failures and NULL pointer dereferences. Fix it by suspending writes around quotaoff() call. Since the filesystem is synced, no dandling references to dquots from SU workitems can left behind, which means that quotaoff succeeds. The complication there is that quotaoff VFS op is performed with the mount point busied, while to suspend, we need to start write on the mp. If vn_start_write() is called on busied mp, system might deadlock against parallel unmount request. Handle this by unbusy-ing mp before starting write, which in turn requires changing the quotaoff() interface to return with the mount point not busied, same as was done for quotaon().

To add to the point, directories where the dirent is added or removed, are locked exclusively as well.
