2008-06-18sata_mv: warn on PIO with multiple DRQsMark Lord
Chip errata sometimes prevents reliable use of PIO commands which involve more than a single DRQ (data request). In normal operation, libata should not generate such PIO commands (uses DMA instead), but they could be sent in via SG_IO from userspace. A full workaround might be to break up such commands into sequences of single DRQ ones, but that's just way too complex for something that doesn't normally happen in real life. So, allow the attempt (it often works, despite the errata), but log the event for reference when somebody screams.

2008-06-19agp: two-stage page destruction issueJan Beulich
besides it apparently being useful only in 2.6.24 (the changes in 2.6.25 really mean that it could be converted back to a single-stage mechanism), I'm seeing an issue in Xen Dom0 kernels, which is caused by the calling of gart_to_virt() in the second stage invocations of the destroy function. I think that besides this being a real issue with Xen (where unmap_page_from_agp() is not just a page table attribute change), this also is invalid from a theoretical perspective: One should not assume that gart_to_virt() is still valid after unmapping a page. So minimally (keeping the 2-stage mechanism) a patch like the one below would be needed. Jan Signed-off-by: Dave Airlie <airlied@redhat.com>

2008-06-19firewire: deadline for PHY config transmissionStefan Richter
If the low-level driver failed to initialize a card properly without noticing it, fw-core was blocked indefinitely when trying to send a PHY config packet. This hung up the events kernel thread, e.g. locked up keyboard input. https://bugzilla.redhat.com/show_bug.cgi?id=444694 https://bugzilla.redhat.com/show_bug.cgi?id=446763 This problem was introduced between 2.6.25 and 2.6.26-rc1 by commit 2a0a2590498be7b92e3e76409c9b8ee722e23c8f "firewire: wait until PHY configuration packet was transmitted (fix bus reset loop)". The solution is to wait with timeout. I tested it with 7 different working controllers and 1 non-working controller. On the working ones, the packet callback complete()s usually --- but not always --- before a timeout of 10ms. Hence I chose a safer timeout of 100ms. On the few tests with the non-working controller ALi M5271, PHY config packet transmission always timed out so far. (Fw-ohci needs to be fixed for this controller independently of this deadline fix. Often the core doesn't even attempt to send a phy config because not even self ID reception works.) Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2008-06-19firewire: fill_bus_reset_event needs lock protectionStefan Richter
Callers of fill_bus_reset_event() have to take card->lock. Otherwise access to node data may oops if node removal is in progress. A lockless alternative would be - event->local_node_id = card->local_node->node_id; + tmp = fw_node_get(card->local_node); + event->local_node_id = tmp->node_id; + fw_node_put(tmp); and ditto with the other node pointers which fill_bus_reset_event() accesses. But I went the locked route because one of the two callers already holds the lock. As a bonus, we don't need the memory barrier anymore because device->generation and device->node_id are written in a card->lock protected section.

OHCI 1.1 clause 5.10 requires that selfIDBufferPtr is valid when a 1 is written into LinkControl.rcvSelfID. This driver bug has so far not been known to cause harm because most chips obviously accept a later selfIDBufferPtr write, at least before HCControl.linkEnable is written.

We want the rcvPhyPkt bit in LinkControl off before we start using the chip. However, the spec says that the reset value of it is undefined. Hence switch it explicitly off. https://bugzilla.redhat.com/show_bug.cgi?id=244576#c48 shows that for example the nForce2 integrated FireWire controller seems to have it on by default.

2008-06-19firewire: don't panic on invalid AR request bufferStefan Richter
BUG() at this place is wrong. (Unless if the low level driver would already do higher-level input validation of incoming request headers.)

2008-06-18[POWERPC] Clear sub-page HPTE present bits when demoting page sizePaul Mackerras
When we demote a slice from 64k to 4k, and we are about to insert an HPTE for a 4k subpage and we notice that there is an existing 64k HPTE, we first invalidate that HPTE before inserting the new 4k subpage HPTE. Since the bits that encode which hash bucket the old HPTE was in overlap with the bits that encode which of the 16 subpages have HPTEs, we need to clear out the subpage HPTE-present bits before starting to insert HPTEs for the 4k subpages. If we don't do that, we can erroneously think that a subpage already has an HPTE when it doesn't. That in itself wouldn't be such a problem except that when we go to update the HPTE that we think is present on machines with a hypervisor, the hypervisor can tell us that the HPTE we think is there is actually there even though it isn't, which can lead to a process getting stuck in a loop, continually faulting. The reason for the confusion is that the AVPN (abbreviated virtual page number) we are looking for in the HPTE for a 4k subpage can actually match the AVPN in a stale HPTE for another 64k page. For example, the HPTE for the 4k subpage at 0x84000f000 will be in the same hash bucket and have the same AVPN as the HPTE for the 64k page at 0x8400f0000. This fixes the code to clear out the subpage HPTE-present bits. Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-06-18netlink: genl: fix circular lockingPatrick McHardy
genetlink has a circular locking dependency when dumping the registered families: - dump start: genl_rcv() : take genl_mutex genl_rcv_msg() : call netlink_dump_start() while holding genl_mutex netlink_dump_start(), netlink_dump() : take nlk->cb_mutex ctrl_dumpfamily() : try to detect this case and not take genl_mutex a second time - dump continuance: netlink_rcv() : call netlink_dump netlink_dump : take nlk->cb_mutex ctrl_dumpfamily() : take genl_mutex Register genl_lock as callback mutex with netlink to fix this. This slightly widens an already existing module unload race, the genl ops used during the dump might go away when the module is unloaded. Thomas Graf is working on a seperate fix for this.

2008-06-18Revert "mac80211: Use skb_header_cloned() on TX path."David S. Miller
This reverts commit 608961a5eca8d3c6bd07172febc27b5559408c5d. The problem is that the mac80211 stack not only needs to be able to muck with the link-level headers, it also might need to mangle all of the packet data if doing sw wireless encryption. This fixes kernel bugzilla #10903. Thanks to Didier Raboud (for the bugzilla report), Andrew Prince (for bisecting), Johannes Berg (for bringing this bisection analysis to my attention), and Ilpo (for trying to analyze this purely from the TCP side). In 2.6.27 we can take another stab at this, by using something like skb_cow_data() when the TX path of mac80211 ends up with a non-NULL tx->key. The ESP protocol code in the IPSEC stack can be used as a model for implementation. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-17af_unix: fix 'poll for write'/ connected DGRAM socketsRainer Weikusat
The unix_dgram_sendmsg routine implements a (somewhat crude) form of receiver-imposed flow control by comparing the length of the receive queue of the 'peer socket' with the max_ack_backlog value stored in the corresponding sock structure, either blocking the thread which caused the send-routine to be called or returning EAGAIN. This routine is used by both SOCK_DGRAM and SOCK_SEQPACKET sockets. The poll-implementation for these socket types is datagram_poll from core/datagram.c. A socket is deemed to be writeable by this routine when the memory presently consumed by datagrams owned by it is less than the configured socket send buffer size. This is always wrong for connected PF_UNIX non-stream sockets when the abovementioned receive queue is currently considered to be full. 'poll' will then return, indicating that the socket is writeable, but a subsequent write result in EAGAIN, effectively causing an (usual) application to 'poll for writeability by repeated send request with O_NONBLOCK set' until it has consumed its time quantum. The change below uses a suitably modified variant of the datagram_poll routines for both type of PF_UNIX sockets, which tests if the recv-queue of the peer a socket is connected to is presently considered to be 'full' as part of the 'is this socket writeable'-checking code. The socket being polled is additionally put onto the peer_wait wait queue associated with its peer, because the unix_dgram_sendmsg routine does a wake up on this queue after a datagram was received and the 'other wakeup call' is done implicitly as part of skb destruction, meaning, a process blocked in poll because of a full peer receive queue could otherwise sleep forever if no datagram owned by its socket was already sitting on this queue. Among this change is a small (inline) helper routine named 'unix_recvq_full', which consolidates the actual testing code (in three different places) into a single location.

2008-06-17atl1: relax eeprom mac address error checkRadu Cristescu
The atl1 driver tries to determine the MAC address thusly: - If an EEPROM exists, read the MAC address from EEPROM and validate it. - If an EEPROM doesn't exist, try to read a MAC address from SPI flash. - If that fails, try to read a MAC address directly from the MAC Station Address register. - If that fails, assign a random MAC address provided by the kernel. We now have a report of a system fitted with an EEPROM containing all zeros where we expect the MAC address to be, and we currently handle this as an error condition. Turns out, on this system the BIOS writes a valid MAC address to the NIC's MAC Station Address register, but we never try to read it because we return an error when we find the all- zeros address in EEPROM. This patch relaxes the error check and continues looking for a MAC address even if it finds an illegal one in EEPROM.
