2008-06-27[netdrvr] Fix IOMMU overflow checking in s2io.cAndi Kleen
s2io has IOMMU overflow checking, but unfortunately it is wrong. It didn't use the standard macros, which meant that it only worked on POWER and SPARC because only those define DMA_ERROR_CODE. Convert it to use the standard macros instead. I also commented two more bugs in the IOMMU handling. It assumes that 0 DMA addresses cannot happen, but that's not true in all IOMMU setups. The information if a buffer has been already mapped needs to be stored elsewhere. Didn't fix those because it needs careful checking of the buffer handling by the maintainers.

Receiving packets while we are cleaning up a network namespace is a racy proposition. It is possible when the packet arrives that we have removed some but not all of the state we need to fully process it. We have the choice of either playing wack-a-mole with the cleanup routines or simply dropping packets when we don't have a network namespace to handle them.

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.

2008-06-17net/enc28j60: low power modeDavid Brownell
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.

2008-06-17ibm_newemac: select CRC32 in KconfigJosh Boyer
The ibm_newemac driver requires ether_crc to be defined. Apparently it is possible to generate a .config without CONFIG_CRC32 set which causes the following link errors if IBM_NEW_EMAC is selected: LD .tmp_vmlinux1 drivers/built-in.o: In function `emac_hash_mc': core.c:(.text+0x2f524): undefined reference to `crc32_le' core.c:(.text+0x2f528): undefined reference to `bitrev32' make: *** [.tmp_vmlinux1] Error 1 This patch has IBM_NEW_EMAC select CRC32 so we don't hit this error.

2008-06-17xfrm: fix fragmentation for ipv4 xfrm tunnelSteffen Klassert
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. We have to mask the frag_off field to only keep the IP_DF flag from the original packet.

The missing l3num initialization is enough for this, this patch changes it to use AF_UNSPEC to make it more explicit though.
