It would probably be better to return EFAULT like clock_gettime() does by passing the pointer to copyout(), but I presume it was written to not fail on purpose in the original code. I'll defer to -standards on this one. Reported by: bde Notes: svn path=/head/; revision=130884

This will typically add one or two buses to CAM, which will be numbered starting at 32 to allow room for CISS proxy buses.

| | | | | | | | | | | | | | where it is known to detect a problem but the problem is not very easy to fix. The warning became very common recently after a call to calcru() was added to fill_kinfo_thread(). Another (much older) cause of "negative times" (actually non-monotonic times) was fixed in rev.1.237 of kern_exit.c. Print separate messages for non-monotonic and negative times.

* (1) Removed the bogus condition "p->p_pid != 1" on calling sched_exit()Bruce Evans2004-06-211-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | from exit1(). sched_exit() must be called unconditionally from exit1(). It was called almost unconditionally because the only exits on system shutdown if at all. (2) Removed the comment that presumed to know what sched_exit() does. sched_exit() does different things for the ULE case. The call became essential when it started doing load average stuff, but its caller should not know that. (3) Didn't fix bugs caused by bitrot in the condition. The condition was last correct in rev.1.208 when it was in wait1(). There p was spelled curthread->td_proc and was for the waiting parent; now p is for the exiting child. The condition was to avoid lowering init's priority. It should be in sched_exit() itself. Lowering of priorities is broken in other ways in at least the 4BSD scheduler, and doing it for init causes less noticeable problems than doing it for for shells.

This is now required due to the recent locking changes to ttys and prevents a panic due to locking an unitialized t_mtx. - Allow the pci driver to be unloaded. This involved moving the call rp_releaseresource() to the end of rp_pcireleaseresource(), since rp_pcireleaseresource() uses ctlp->dev, which is freed by rp_releaseresource(). - Allow the generic part of the driver to be unattached by providing a hook to cancel timeouts.

* Merge next step in socket buffer locking:Robert Watson2004-06-216-69/+558
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - sowakeup() now asserts the socket buffer lock on entry. Move the call to KNOTE higher in sowakeup() so that it is made with the socket buffer lock held for consistency with other calls. Release the socket buffer lock prior to calling into pgsigio(), so_upcall(), or aio_swake(). Locking for this event management will need revisiting in the future, but this model avoids lock order reversals when upcalls into other subsystems result in socket/socket buffer operations. Assert that the socket buffer lock is not held at the end of the function. - Wrapper macros for sowakeup(), sorwakeup() and sowwakeup(), now have _locked versions which assert the socket buffer lock on entry. If a wakeup is required by sb_notify(), invoke sowakeup(); otherwise, unconditionally release the socket buffer lock. This results in the socket buffer lock being released whether a wakeup is required or not. - Break out socantsendmore() into socantsendmore_locked() that asserts the socket buffer lock. socantsendmore() unconditionally locks the socket buffer before calling socantsendmore_locked(). Note that both functions return with the socket buffer unlocked as socantsendmore_locked() calls sowwakeup_locked() which has the same properties. Assert that the socket buffer is unlocked on return. - Break out socantrcvmore() into socantrcvmore_locked() that asserts the socket buffer lock. socantrcvmore() unconditionally locks the socket buffer before calling socantrcvmore_locked(). Note that both functions return with the socket buffer unlocked as socantrcvmore_locked() calls sorwakeup_locked() which has similar properties. Assert that the socket buffer is unlocked on return. - Break out sbrelease() into a sbrelease_locked() that asserts the socket buffer lock. sbrelease() unconditionally locks the socket buffer before calling sbrelease_locked(). sbrelease_locked() now invokes sbflush_locked() instead of sbflush(). - Assert the socket buffer lock in socket buffer sanity check functions sblastrecordchk(), sblastmbufchk(). - Assert the socket buffer lock in SBLINKRECORD(). - Break out various sbappend() functions into sbappend_locked() (and variations on that name) that assert the socket buffer lock. The !_locked() variations unconditionally lock the socket buffer before calling their _locked counterparts. Internally, make sure to call _locked() support routines, etc, if already holding the socket buffer lock. - Break out sbinsertoob() into sbinsertoob_locked() that asserts the socket buffer lock. sbinsertoob() unconditionally locks the socket buffer before calling sbinsertoob_locked(). - Break out sbflush() into sbflush_locked() that asserts the socket buffer lock. sbflush() unconditionally locks the socket buffer before calling sbflush_locked(). Update panic strings for new function names. - Break out sbdrop() into sbdrop_locked() that asserts the socket buffer lock. sbdrop() unconditionally locks the socket buffer before calling sbdrop_locked(). - Break out sbdroprecord() into sbdroprecord_locked() that asserts the socket buffer lock. sbdroprecord() unconditionally locks the socket buffer before calling sbdroprecord_locked(). - sofree() now calls socantsendmore_locked() and re-acquires the socket buffer lock on return. It also now calls sbrelease_locked(). - sorflush() now calls socantrcvmore_locked() and re-acquires the socket buffer lock on return. Clean up/mess up other behavior in sorflush() relating to the temporary stack copy of the socket buffer used with dom_dispose by more properly initializing the temporary copy, and selectively bzeroing/copying more carefully to prevent WITNESS from getting confused by improperly initialized mutexes. Annotate why that's necessary, or at least, needed. - soisconnected() now calls sbdrop_locked() before unlocking the socket buffer to avoid locking overhead.

* Fix the following error:Marcel Moolenaar2004-06-201-0/+2
| | | | | | | | | | | | | | | | | ld: locore.o: non-pic code with imm relocation against dynamic symbol `__gp' With binutils 2.15, ld(1) defines the implicit/automatic symbol __gp as a dynamic symbol and thus will now complain when used in a non-PIC fashion (the immediate relocation used to set the GP register). Resolve this by defining __gp in the linker script. Make sure __gp is aligned on a 16-byte boundary. Note: the 0x200000 magic offset is due to having a 22-bit GP-relative relocation. The GOT will be accessed with negative offsets from GP. Notes: svn path=/head/; revision=130829

* Remove one more unneeded reference to arpcom.ac_netgraph.Bill Paul2004-06-201-10/+34
| | | | | | | | | | | | | | | | | | | Tweak things so that ng_fec has a chance of working with things other than ethernet. Use ifp->if_output of the underlying interfaces and use IF_HANDOFF() rather than depending on ether_output() and ether_output_frame() explicitly. Also, don't insist that underlying devices be IFM_ETHER when checking their link states in the link monitor code. With these changes, I was able to create a two channel bundle consisting of one ethernet interface and one 802.11 wireless device (via ndis). Note that this only works because both devices use the same if_output vector: ng_fec will not let you bundle devices with different output vectors together (it really doesn't make sense to do that).
