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: NDave Airlie <airlied@redhat.com>

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: NPaul Mackerras <paulus@samba.org>

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.

This reverts commit 608961a5. 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: NDavid S. Miller <davem@davemloft.net>

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.

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.

Keep enc28j60 chips in low-power mode when they're not in use. At typically 120 mA, these chips run hot even when idle; this low power mode cuts that power usage by a factor of around 100. This version provides a generic routine to poll a register until its masked value equals some value ... e.g. bit set or cleared. It's basically what the previous wait_phy_ready() did, but this version is generalized to support the handshaking needed to enter and exit low power mode.

Most users by far do not care about the exact return value (they only really care about whether the copy succeeded in its entirety or not), but a few special core routines actually care deeply about exactly how many bytes were copied from user space. And the unrolled versions of the x86-64 user copy routines would sometimes report that it had copied more bytes than it actually had. Very few uses actually have partial copies to begin with, but to make this bug even harder to trigger, most x86 CPU's use the "rep string" instructions for normal user copies, and that version didn't have this issue. To make it even harder to hit, the one user of this that really cared about the return value (and used the uncached version of the copy that doesn't use the "rep string" instructions) was the generic write routine, which pre-populated its source, once more hiding the problem by avoiding the exception case that triggers the bug. In other words, very special thanks to Bron Gondwana who not only triggered this, but created a test-program to show it, and bisected the behavior down to commit 08291429 ("mm: fix pagecache write deadlocks") which changed the access pattern just enough that you can now trigger it with 'writev()' with multiple iovec's. That commit itself was not the cause of the bug, it just allowed all the stars to align just right that you could trigger the problem. [ Side note: this is just the minimal fix to make the copy routines (with __copy_from_user_inatomic_nocache as the particular version that was involved in showing this) have the right return values. We really should improve on the exceptional case further - to make the copy do a byte-accurate copy up to the exact page limit that causes it to fail. As it is, the callers have to do extra work to handle the limit case gracefully. ] Reported-by: NBron Gondwana <brong@fastmail.fm> Cc: Nick Piggin <npiggin@suse.de> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Andi Kleen <andi@firstfloor.org> Cc: Al Viro <viro@ZenIV.linux.org.uk> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org> (which didn't have this problem), and since most users that do the carethis was very hard to trigger, but

When generating the ip header for the transformed packet we just copy the frag_off field of the ip header from the original packet to the ip header of the new generated packet. If we receive a packet as a chain of fragments, all but the last of the new generated packets have the IP_MF flag set.
