2011-03-09ipv6: Don't create clones of host routes.David S. Miller1-1/+3
Addresses https://bugzilla.kernel.org/show_bug.cgi?id=29252 Addresses https://bugzilla.kernel.org/show_bug.cgi?id=30462 In commit d80bc0fd262ef840ed4e82593ad6416fa1ba3fc4 ("ipv6: Always clone offlink routes.") we forced the kernel to always clone offlink routes. The reason we do that is to make sure we never bind an inetpeer to a prefixed route. The logic turned on here has existed in the tree for many years, but was always off due to a protecting CPP define. So perhaps it's no surprise that there is a logic bug here. The problem is that we canot clone a route that is already a host route (ie. has DST_HOST set). Because if we do, an identical entry already exists in the routing tree and therefore the ip6_rt_ins() call is going to fail. This sets off a series of failures and high cpu usage, because when ip6_rt_ins() fails we loop retrying this operation a few times in order to handle a race between two threads trying to clone and insert the same host route at the same time. Fix this by simply using the route as-is when DST_HOST is set. Reported-by: slash@ac.auone-net.jp Reported-by: Ernst Sjöstrand <ernstp@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-10net: don't allow CAP_NET_ADMIN to load non-netdev kernel modulesVasiliy Kulikov5-5/+16
Since a8f80e8ff94ecba629542d9b4b5f5a8ee3eb565c any process with CAP_NET_ADMIN may load any module from /lib/modules/. This doesn't mean that CAP_NET_ADMIN is a superset of CAP_SYS_MODULE as modules are limited to /lib/modules/**. However, CAP_NET_ADMIN capability shouldn't allow anybody load any module not related to networking. This patch restricts an ability of autoloading modules to netdev modules with explicit aliases. This fixes CVE-2011-1019. Arnd Bergmann suggested to leave untouched the old pre-v2.6.32 behavior of loading netdev modules by name (without any prefix) for processes with CAP_SYS_MODULE to maintain the compatibility with network scripts that use autoloading netdev modules by aliases like "eth0", "wlan0". Currently there are only three users of the feature in the upstream kernel: ipip, ip_gre and sit. root@albatros:~# capsh --drop=$(seq -s, 0 11),$(seq -s, 13 34) -- root@albatros:~# grep Cap /proc/$$/status CapInh: 0000000000000000 CapPrm: fffffff800001000 CapEff: fffffff800001000 CapBnd: fffffff800001000 root@albatros:~# modprobe xfs FATAL: Error inserting xfs (/lib/modules/2.6.38-rc6-00001-g2bf4ca3/kernel/fs/xfs/xfs.ko): Operation not permitted root@albatros:~# lsmod | grep xfs root@albatros:~# ifconfig xfs xfs: error fetching interface information: Device not found root@albatros:~# lsmod | grep xfs root@albatros:~# lsmod | grep sit root@albatros:~# ifconfig sit sit: error fetching interface information: Device not found root@albatros:~# lsmod | grep sit root@albatros:~# ifconfig sit0 sit0 Link encap:IPv6-in-IPv4 NOARP MTU:1480 Metric:1 root@albatros:~# lsmod | grep sit sit 10457 0 tunnel4 2957 1 sit For CAP_SYS_MODULE module loading is still relaxed: root@albatros:~# grep Cap /proc/$$/status CapInh: 0000000000000000 CapPrm: ffffffffffffffff CapEff: ffffffffffffffff CapBnd: ffffffffffffffff root@albatros:~# ifconfig xfs xfs: error fetching interface information: Device not found root@albatros:~# lsmod | grep xfs xfs 745319 0 Reference: https://lkml.org/lkml/2011/2/24/203 Signed-off-by: Vasiliy Kulikov <segoon@openwall.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Acked-by: David S.

2011-03-10powerpc/iseries: Fix early init access to lppacaBenjamin Herrenschmidt4-17/+20
The combination of commit 8154c5d22d91cd16bd9985b0638c8957e4688d0e and 93c22703efa72c7527dbd586d1951c1f4a85fd70 Broke boot on iSeries. The problem is that iSeries very early boot code, which generates the device-tree and runs before our normal early initializations does need access the lppaca's very early, before the PACA array is initialized, and in fact even before the boot PACA has been initialized (it contains all 0's at this stage). However, the first patch above makes that code use the new llpaca_of(cpu) accessor, which itself is changed by the second patch to use the PACA array. We fix that by reverting iSeries to directly dereferencing the array. In addition, we fix all iterators in the iSeries code to always skip CPU whose number is above 63 which is the maximum size of that array and the maximum number of supported CPUs on these machines. Additionally, we make sure the boot_paca is properly initialized in our early startup code. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2011-03-09ipv4: Fix erroneous uses of ifa_address.David S. Miller1-3/+3
In usual cases ifa_address == ifa_local, but in the case where SIOCSIFDSTADDR sets the destination address on a point-to-point link, ifa_address gets set to that destination address. Therefore we should use ifa_local when we want the local interface address. There were two cases where the selection was done incorrectly: 1) When devinet_ioctl() does matching, it checks ifa_address even though gifconf correct reported ifa_local to the user 2) IN_DEV_ARP_NOTIFY handling sends a gratuitous ARP using ifa_address instead of ifa_local.

2011-03-09perf symbols: Avoid resolving [kernel.kallsyms] to real path for buildid cacheLin Ming1-3/+8
kallsyms has a virtual file name [kernel.kallsyms]. Currently, it can't be added to buildid cache successfully because the code (build_id_cache__add_s) tries to resolve [kernel.kallsyms] to a real absolute pathname and that fails. Fixes it by not resolving it and just use the name [kernel.kallsyms]. So dir ~/.debug/[kernel.kallsyms] is created.

2011-03-08r6040: fix multicast operationsShawn Lin1-47/+64
The original code does not work well when the number of mulitcast address to handle is greater than MCAST_MAX. It only enable promiscous mode instead of multicast hash table mode, so the hash table function will not be activated and all multicast frames will be recieved in this condition. This patch fixes the following issues with the r6040 NIC operating in multicast: 1) When the IFF_ALLMULTI flag is set, we should write 0xffff to the NIC hash table registers to make it process multicast traffic. 2) When the number of multicast address to handle is smaller than MCAST_MAX, we should use the NIC multicast registers MID1_{L,M,H}. 3) The hashing of the address was not correct, due to an invalid substraction (15 - (crc & 0x0f)) instead of (crc & 0x0f) and an incorrect crc algorithm (ether_crc_le) instead of (ether_crc). 4) If necessary, we should set HASH_EN flag in MCR0 to enable multicast hash table function.

2011-03-08mmc: fix CONFIG_MMC_UNSAFE_RESUME regressionOhad Ben-Cohen1-1/+1
30201e7f3 ("mmc: skip detection of nonremovable cards on rescan") allowed skipping detection of nonremovable cards on mmc_rescan(). The intention was to only skip detection of hardwired cards that cannot be removed, so make sure this is indeed the case by directly checking for (lack of) MMC_CAP_NONREMOVABLE, instead of using mmc_card_is_removable(), which is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. The user-visible symptom of the bug this patch fixes is that no "mmc: card XXXX removed" message appears in dmesg when a card is removed and CONFIG_MMC_UNSAFE_RESUME=y.

2011-03-08Btrfs: make sure not to return overlapping extents to fiemapChris Mason1-6/+27
The btrfs fiemap code was incorrectly returning duplicate or overlapping extents in some cases. cp was blindly trusting this result and we would end up with a destination file that was bigger than the original because some bytes were copied twice. The fix here adjusts our offsets to make sure we're always moving forward in the fiemap results. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2011-03-08unfuck proc_sysctl ->d_compare()Al Viro4-13/+31
a) struct inode is not going to be freed under ->d_compare(); however, the thing PROC_I(inode)->sysctl points to just might. Fortunately, it's enough to make freeing that sucker delayed, provided that we don't step on its ->unregistering, clear the pointer to it in PROC_I(inode) before dropping the reference and check if it's NULL in ->d_compare(). b) I'm not sure that we *can* walk into NULL inode here (we recheck dentry->seq between verifying that it's still hashed / fetching dentry->d_inode and passing it to ->d_compare() and there's no negative hashed dentries in /proc/sys/*), but if we can walk into that, we really should not have ->d_compare() return 0 on it! Said that, I really suspect that this check can be simply killed. Nick? Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
