* There is a consensus that ifaddr.ifa_addr should never be NULL,Yaroslav Tykhiy2006-06-2911-50/+28
| | | | | | | | | | | | | except in places dealing with ifaddr creation or destruction; and in such special places incomplete ifaddrs should never be linked to system-wide data structures. Therefore we can eliminate all the superfluous checks for "ifa->ifa_addr != NULL" and get ready to the system crashing honestly instead of masking possible bugs.

* Fix semctl(2) breakage from the previous commit. Previously __semctl() hadJohn Baldwin2006-06-291-7/+12
| | | | | | | | | | | | | | | | a local 'semid' variable which was the array index and used uap->semid as the original IPC id. During the kern_semctl() conversion those two variables were collapsed into a single 'semid' variable breaking the places that needed the original IPC ID. To fix, add a new 'semidx' variable to hold the array index and leave 'semid' unmolested as the IPC id. While I'm here, explicitly document that the (undocumented, at least in semctl(2)) SEM_STAT command curiously expects an array index in the 'semid' parameter rather than an IPC id.

* Detach the interface first, do vlan_unconfig() then.Yaroslav Tykhiy2006-06-291-9/+3
| | | | | | | | | | | | | | | | | | Previously, another thread could get a pointer to the interface by scanning the system-wide list and sleep on the global vlan mutex held by vlan_unconfig(). The interface was gone by the time the other thread woke up. In order to be able to call vlan_unconfig() on a detached interface, remove the purely cosmetic bzero'ing of IF_LLADDR from the function because a detached interface has no addresses.

* Properly detect the RTL8168(B?) again. RealTek sent me a bunch of sampleBill Paul2006-06-282-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cards: the chips are all marked "RTL8111B", but they put stickers on the back that say "RTL8168B/8111B". The manual says there's only one HWREV code for both the 8111B and 8168B devices, which is 0x30000000, but the cards they sent me actually report HWREV of 0x38000000. Deciding to trust the hardware in front of me rather than a possibly incorrect manual (it wouldn't be the first time the HWREVs were incorrectly documented), I changed the 8168 revision code. It turns out this was a mistake though: 0x30000000 really is a valid for the 8168. There are two possible reasons for there to be two different HWREVs: 1) 0x30000000 is used only for the 8168B and 0x38000000 is only for the 8111B. 2) There were 8111/8168 rev A devices which both used code 0x30000000, and the 8111B/8168B both use 0x38000000. The product list on the RealTek website doesn't mention the existence of any 8168/8111 rev A chips being in production though, and I've never seen one, so until I get clarification from RealTek, I'm going to assume that 0x30000000 is just for the 8168B and 0x38000000 is for the 8111B only. So, the HWREV code for the 8168 has been put back to 0x30000000, a new 8111 HWREV code has been added, and there are now separate entries for recognizing both devices in the device list. This will allow all devices to work, though if it turns out I'm wrong I may need to change the ID strings Notes: svn path=/head/; revision=160008

* Updated the XBOX kernel to use the new nfe(4) driver obtained fromRink Springer2006-06-271-1/+1
| | | | | | | | | | | | | | OpenBSD. This driver seems to give a small performance increase, and should lead to better maintainability in the future. The nForce Ethernet-specific hack in sys/i386/xbox/xbox.c is still required, judging from dev/nfe/if_nfe.c. The condition it hacks will almost certainly only occur on XBOX-es anyway, so it is best left there. Approved by: imp (mentor) Notes: svn path=/head/; revision=159997

* Make several changes to pmap_enter_quick_locked():Alan Cox2006-06-271-20/+39
| | | | | | | | | | | | | | | | | | | | | 1. Make the caller responsible for performing pmap_install(). This reduces the number of times that pmap_install() is performed by pmap_enter_object() from twice per page to twice overall. 2. Don't block if pmap_find_pte() is unable to allocate a PTE. If it did block, then it might wind up mapping a cache page. Specifically, if pmap_enter_quick_locked() slept when called from pmap_enter_object(), the page daemon could change an active or inactive page into a cache page just before it was to be mapped. 3. Bail out of pmap_enter_quick_locked() if pv entries aren't plentiful. In other words, don't force the allocation of a pv entry if they aren't readily available.

| | | | | | | | | | | | | | | | pmap_copy() if the mapping is VM_INHERIT_SHARE. Suppose the mapping is also wired. vmspace_fork() clears the wiring attributes in the vm map entry but pmap_copy() copies the PG_W attribute in the PTE. I don't think this is catastrophic. It blocks pmap_remove_pages() from destroying the mapping and corrupts the pmap's wiring count. This revision fixes the problem by changing pmap_copy() to clear the PG_W attribute.
