* MFC of r249848:Randall Stewart2013-04-251-1/+1
| | | | | | | | | | | | | | | | | | | This fixes the issue with the "randomly changing" default route. What it was is there are two places in ip_output.c where we do a goto again. One place was fine, it copies out the new address and then resets dst = ro->rt_dst; But the other place does *not* do that, which means earlier when we found the gateway, we have dst pointing there aka dst = ro->rt_gateway is done.. then we do a goto again.. bam now we clobber the default route. The fix is just to move the again so we are always doing dst = &ro->rt_dst; in the again loop. Approved by: re@freebsd.org (Josh Paetzel) Notes: svn path=/releng/8.4/; revision=249907

* Merge r249478 from stable/8 to releng/8.4:Robert Watson2013-04-192-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSD 8.0 introduced inpcb reference counting, and FreeBSD 8.1 began using that reference count to protect inpcb stability in udp_pcblist() and other monitoring functions, preventing the inpcb from being garbage collected across potentially sleeping copyout() operations despite the inpcb zone becoming shrinkable. However, this introduced a race condition in which inp->inp_socket() might become NULL as a result of the socket being freed, but before the inpcb we removed from the global list of connections, allowing it to be exposed to a third thread invoking udp_input() or udp6_input() which would try to indirect through inp_socket without testing it for NULL. This might occur with particular regularity on systems that frequently run netstat, or which use SNMP for connection monitoring. Later FreeBSD releases use a different reference/destruction model, but stable/8 remained affected in FreeBSD 8.2 and 8.3; the problem could be spotted on very high-load UDP services, such as top-level name servers. An Errata Note for 8.x branches under continuing support might be appropriate. Regardless, this fix should be merged to releng/8.4 prior to 8.4-RELEASE.

| | | | | | | | | | | | | | | | | | | | | | | - Fix two possible overflows when testing if ELF program headers are on the first page: 1. Cast uint16_t operands in a multiplication to unsigned int because otherwise the implicit promotion to int results in a signed multiplication that can overflow and the behaviour on integer overflow is undefined. 2. Replace (offset + size > PAGE_SIZE) with (size > PAGE_SIZE - offset) because the sum may overflow. - Use the same tests to see if the path to the interpreter is on the first page. There's no overflow here because size is already limited by MAXPATHLEN, but the compiler optimises the new tests better. Also fix an off-by-one error. - Simplify tests to see if an ELF note program header is on the first page. This also fixes an off-by-one error.

| | | | | | | | | | | | | | | | | | | r241438 broke IPMI access on Sun Fire X2200 M2(BCM5715). Fix the IPMI regression by sending BGE_FW_DRV_STATE_UNLOAD to ASF/IPMI firmware in driver attach phase. Sending heartheat to ASF/IPMI is enabled only after upping interface so setting driver state to BGE_FW_DRV_STATE_START in attach phase broke IPMI access. While I'm here, add NVRAM arbitration lock before performing controller reset. ASF/IPMI firmware may be able to access the NVRAM while controller reset is in progress. Without the arbitration lock before resetting the controller, ASF/IPMI may not initialize properly. Approved by: re (glebius) Notes: svn path=/releng/8.4/; revision=248860

| | | | | | | | | | | | | | | | | Ensure that all cases that enqueue a netgraph item for delivery by a ngthread properly set the item's depth to 1. In particular, prior to this change if ng_snd_item failed to acquire a lock on a node, the item's depth would not be set at all. This fix ensures that the error code from rcvmsg/ rcvdata is properly passed back to the apply callback. For example, this fixes a bug where an error from rcvmsg/rcvdata would not previously propagate back to a libnetgraph consumer when the message was queued.

| | | | | | | | | | | | | | | | | | | | | | Some aac(4) adapters will always report that a direct access device is offline in response to a INQUIRY command that does not retreive vital product data(I personally have observed the behaviour on an Adaptec 2405 and a 5805). Force the peripheral qualifier to "connected" so that upper layers correctly recognize that a disk is present. This bug was uncovered by r216236. Prior to that fix, aac(4) was accidentally clearing the peripheral qualifier for all inquiry commands. This fixes an issue where passthrough devices were not created for disks behind aac(4) controllers suffering from the bug. I have verified that if a disk is not present that we still properly detect that and not create the passthrough device.
