Make the session keyring per-thread rather than per-process, but still inherited from the parent thread to solve a problem with PAM and gdm. The problem is that join_session_keyring() will reject attempts to change the session keyring of a multithreaded program but gdm is now multithreaded before it gets to the point of starting PAM and running pam_keyinit to create the session keyring. See: https://bugs.freedesktop.org/show_bug.cgi?id=49211 The reason that join_session_keyring() will only change the session keyring under a single-threaded environment is that it's hard to alter the other thread's credentials to effect the change in a multi-threaded program. The problems are such as: (1) How to prevent two threads both running join_session_keyring() from racing. (2) Another thread's credentials may not be modified directly by this process. (3) The number of threads is uncertain whilst we're not holding the appropriate spinlock, making preallocation slightly tricky. (4) We could use TIF_NOTIFY_RESUME and key_replace_session_keyring() to get another thread to replace its keyring, but that means preallocating for each thread. A reasonable way around this is to make the session keyring per-thread rather than per-process and just document that if you want a common session keyring, you must get it before you spawn any threads - which is the current situation anyway. Whilst we're at it, we can the process keyring behave in the same way. This means we can clean up some of the ickyness in the creds code. Basically, after this patch, the session, process and thread keyrings are about inheritance rules only and not about sharing changes of keyring. Reported-by:

Fix potential NULL pointer dereference in edac_unregister_sysfs() on system boot introduced in 3.6-rc1. Since commit 7a623c03 ("edac: rewrite the sysfs code to use struct device") edac_mc_alloc() no longer initializes embedded kobjects in struct mem_ctl_info. Therefore edac_mc_free() can no longer simply decrement a kobject reference count to free the allocated memory unless the memory controller driver module had also called edac_mc_add_mc(). Now edac_mc_free() will check if the newly embedded struct device has been registered with sysfs before using either the standard device release functions or freeing the data structures itself with logic pulled out of the error path of edac_mc_alloc(). The BUG this patch resolves for me: BUG: unable to handle kernel NULL pointer dereference at (null) EIP is at __wake_up_common+0x1a/0x6a Process modprobe (pid: 933, ti=f3dc6000 task=f3db9520 task.ti=f3dc6000) Call Trace: complete_all+0x3f/0x50 device_pm_remove+0x23/0xa2 device_del+0x34/0x142 edac_unregister_sysfs+0x3b/0x5c [edac_core] edac_mc_free+0x29/0x2f [edac_core] e7xxx_probe1+0x268/0x311 [e7xxx_edac] e7xxx_init_one+0x56/0x61 [e7xxx_edac] local_pci_probe+0x13/0x15 ...

Should be "row" and "tot_csrows" respectively. Which means either memory leak, or out-of-bound reads (which if does not trigger an immediate page fault error, will further lead to kfree() on random addresses). L425: The inner loop is reusing the same iterator "chn" as the outer loop, which could lead to premature end of the outer loop, and hence memory leak. L429: The array index 'i' in mci->csrows[i] is a temporary value used in previous loops, and won't change at all in the current loop. Which means either out-of-bound read and possibly kfree(random number), or the same mci->csrows[i] get freed once and again, and possibly double free for the kfree(csr) in L427. L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory. The buggy code was introduced by commit de3910eb ("edac: change the mem allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1 merge window.

coretemp_init loops with for_each_online_cpu, adding platform_devices and sysfs interfaces, then calls register_hotcpu_notifier. There is a race if a CPU is offlined or onlined after the loop, but before register_hotcpu_notifier. The race might result in the absence of a platform_device+sysfs interface for an online CPU, or the presence of a platform_device+sysfs interface for an offline CPU. A similar race occurs during coretemp_exit, after the module calls unregister_hotcpu_notifier, but before it unregisters all devices, a CPU might offline and a device for an offline CPU will exist for a short while. This fix surrounds for_each_online_cpu and register_hotcpu_notifier with get_online_cpus+put_online_cpus; and surrounds unregister_hotcpu_notifier and device unregistering with get_online_cpus+put_online_cpus.

Nestor Lopez Casado authored
This patch fixes an issue introduced after commit 4ea54542 ("HID: Fix race condition between driver core and ll-driver"). After that commit, hid-core discards any incoming packet that arrives while hid driver's probe function is being executed. This broke the enumeration process of hid-logitech-dj, that must receive control packets in-band with the mouse and keyboard packets. Discarding mouse or keyboard data at the very begining is usually fine, but it is not the case for control packets. This patch forces a re-enumeration of the paired devices when a packet arrives that comes from an unknown device. Based on a patch originally written by Benjamin Tissoires.

Pull networking updates from David Miller: "More bug fixes, nothing gets past these guys" 1) More kernel info leaks found by Mathias Krause, this time in the IPSEC configuration layers. 2) When IPSEC policies change, we do not properly make sure that cached routes (which could now be stale) throughout the system will be revalidated. Fix this by generalizing the generation count invalidation scheme used by ipv4. From Nicolas Dichtel. 3) When repairing TCP sockets, we need to allow to restore not just the send window scale, but the receive one too. Extend the existing interface to achieve this in a backwards compatible way. From Andrey Vagin. 4) A fix for FCOE scatter gather feature validation erroneously caused scatter gather to be disabled for things like AOE too. From Ed L Cashin. 5) Several cases of mishandling of error pointers, from Mathias Krause, Wei Yongjun, and Devendra Naga. 6) Fix gianfar build, from Richard Cochran. 7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao Hongjiang. 8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder. 9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde. 10) The removal of the conditional compilation of the clk support code in the stmmac driver broke things. This is because the interfaces used are the ones that don't also perform the enable/disable of the clk. Fix from Stefan Roese. 11) The QFQ packet scheduler can record out of range virtual start times, resulting later in misbehavior and even crashes. Fix from Paolo Valente. 12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the receiver when the advertised receive window goes to zero. Detect this case and force the processing of the IOAT DMA queue when it happens to avoid getting stuck. Fix from Michal Kubecek. 13) batman-adv assumes that test_bit() returns only 0 or 1, but this is not true for x86 (which returns -1 or 0, via the 'sbb' instruction). Fix from Linus Lussing. 14) Fix small packet corruption in e1000, from Tushar Dave. 15) make_blackhole() in the IPSEC policy code can do one read unlock too many, fix from Li RongQing. 16) The new tcp_try_coalesce() code introduced a bug in TCP URG handling, fix from Eric Dumazet. 17) Fix memory leak in __netif_receive_skb() when doing zerocopy and when hit an OOM condition. From Michael S Tsirkin. 18) netxen blindly deferences pdev->bus->self, which is not guarenteed to be non-NULL. Fix from Nikolay Aleksandrov. 19) Fix a performance regression caused by mistakes in ipv6 checksum validation in the bnx2x driver, fix from Michal Schmidt. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (45 commits) net/stmmac: Use clk_prepare_enable and clk_disable_unprepare net: change return values from -EACCES to -EPERM net/irda: sh_sir: fix return value check in sh_sir_set_baudrate() stmmac: fix return value check in stmmac_open_ext_timer() gianfar: fix phc index build failure ipv6: fix return value check in fib6_add() bnx2x: remove false warning regarding interrupt number can: ti_hecc: fix oops during rmmod can: janz-ican3: fix support for older hardware revisions net: do not disable sg for packets requiring no checksum aoe: assert AoE packets marked as requiring no checksum at91ether: return PTR_ERR if call to clk_get fails xfrm_user: don't copy esn replay window twice for new states xfrm_user: ensure user supplied esn replay window is valid xfrm_user: fix info leak in copy_to_user_tmpl() xfrm_user: fix info leak in copy_to_user_policy() xfrm_user: fix info leak in copy_to_user_state() xfrm_user: fix info leak in copy_to_user_auth() net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200 tcp: restore rcv_wscale in a repair mode (v2) ...

This patch fixes an issue introduced by commit ID 6a81c26f [net/stmmac: remove conditional compilation of clk code], which switched from the internal stmmac_clk_{en}{dis}able calls to clk_{en}{dis}able. By this, calling clk_prepare and clk_unprepare was removed. clk_{un}prepare is mandatory for platforms using common clock framework. Since these drivers are used by SPEAr platform, which supports common clock framework, add clk_{un}prepare() support for them. Otherwise the clocks are not correctly en-/disabled and ethernet support doesn't work. Signed-off-by:

The format_array_alloc() function is fundamentally racy, in that it prints the array twice: once to figure out how much space to allocate for the buffer, and the second time to actually print out the data. If any of the array contents changes in between, the allocation size may be wrong, and the end result may be truncated in odd ways. Just don't do it. Allocate a maximum-sized array up-front, and just format the array contents once. The only user of the u32_array interfaces is the Xen spinlock statistics code, and it has 31 entries in the arrays, so the maximum size really isn't that big, and the end result is much simpler code without the bug.
