2008-12-26cifs: make ipv4_connect take a TCP_Server_Info argJeff Layton
In order to unify the smb_send routines, we need to reorganize the routines that connect the sockets. Have ipv4_connect take a TCP_Server_Info pointer and get the necessary fields from that. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2008-12-26cifs: move allocation of new TCP_Server_Info into separate functionJeff Layton
Clean up cifs_mount a bit by moving the code that creates new TCP sessions into a separate function. Have that function search for an existing socket and then create a new one if one isn't found. Also reorganize the initializion of TCP_Server_Info a bit to prepare for cleanup of the socket connection code.

2008-12-26cifs: account for IPv6 in ses->serverName and clean up netbios name handlingJeff Layton
The current code for setting the session serverName is IPv4-specific. Allow it to be an IPv6 address as well. Use NIP* macros to set the format. This also entails increasing the length of the serverName field, so declare a new macro for RFC1001 name length and use it in the appropriate places. Finally, drop the unicode_server_Name field from TCP_Server_Info since it's not used. We can add it back later if needed, but for now it just wastes memory.

2008-12-24x86: disable X86_PTRACE_BTSIngo Molnar
there's a new ptrace arch level feature in .28: config X86_PTRACE_BTS bool "Branch Trace Store" it has broken fork() handling: the old DS area gets copied over into a new task without clearing it. Fixes exist but they came too late: c5dee61: x86, bts: memory accounting bf53de9: x86, bts: add fork and exit handling and are queued up for v2.6.29. This shows that the facility is still not tested well enough to release into a stable kernel - disable it for now and reactivate in .29. In .29 the hardware-branch-tracer will use the DS/BTS facilities too - hopefully resulting in better code. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-12-23edac: fix edac core deadlock when removing a deviceHarry Ciao
When deleting an edac device, we have to wait for its edac_dev.work to be completed before deleting the whole edac_dev structure. Since we have no idea which work in current edac_poller's workqueue is the work we are conerned about, we wait for all work in the edac_poller's workqueue to be proceseed. This is done via flush_cpu_workqueue() which inserts a wq_barrier into the tail of the workqueue and then sleeping on the completion of this wq_barrier. The edac_poller will wake up sleepers when it is found. EDAC core creates only one kernel worker thread, edac_poller, to run the works of all current edac devices. They share the same callback function of edac_device_workq_function(), which would grab the mutex of device_ctls_mutex first before it checks the device. This is exactly where edac_poller and rmmod would have a great chance to deadlock. In below call trace of rmmod > ... > edac_device_del_device > edac_device_workq_teardown > flush_workqueue > flush_cpu_workqueue, device_ctls_mutex would have already been grabbed by edac_device_del_device(). So, on one hand rmmod would sleep on the completion of a wq_barrier, holding device_ctls_mutex; on the other hand edac_poller would be blocked on the same mutex when it's running any one of works of existing edac evices(Note, this edac_dev.work is likely to be totally irrelevant to the one that is being removed right now)and never would have a chance to run the work of above wq_barrier to wake rmmod up. edac_device_workq_teardown() should not be called within the critical region of device_ctls_mutex. Just like is done in edac_pci_del_device() and edac_mc_del_mc(), where edac_pci_workq_teardown() and edac_mc_workq_teardown() are called after related mutex are released. Moreover, an edac_dev.work should check first if it is being removed. If this is the case, then it should bail out immediately. Since not all of existing edac devices are to be removed, this "shutting flag" should be contained to edac device being removed. The current edac_dev.op_state can be used to serve this purpose. The original deadlock problem and the solution have been witnessed and tested on actual hardware. Without the solution, rmmod an edac driver would result in below deadlock: root@localhost:/root> rmmod mv64x60_edac EDAC DEBUG: mv64x60_dma_err_remove() EDAC DEBUG: edac_device_del_device() EDAC DEBUG: find_edac_device_by_dev() (hang for a moment) INFO: task edac-poller:2030 blocked for more than 120 seconds.

2008-12-20Null pointer deref with hrtimer_try_to_cancel()Thomas Gleixner
Impact: Prevent kernel crash with posix timer clockid CLOCK_MONOTONIC_RAW commit 2d42244ae71d6c7b0884b5664cf2eda30fb2ae68 (clocksource: introduce CLOCK_MONOTONIC_RAW) introduced a new clockid, which is only available to read out the raw not NTP adjusted system time. The above commit did not prevent that a posix timer can be created with that clockid. The timer_create() syscall succeeds and initializes the timer to a non existing hrtimer base. When the timer is deleted either by timer_delete() or by the exit() cleanup the kernel crashes. Prevent the creation of timers for CLOCK_MONOTONIC_RAW by setting the posix clock function to no_timer_create which returns an error code.

Impact: fix deadlock This is in response to the following bug report: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12100 Subject : resume (S2R) broken by Intel microcode module, on A110L Submitter : Andreas Mohr <andi@lisas.de> Date : 2008-11-25 08:48 (19 days old) Handled-By : Dmitry Adamushko <dmitry.adamushko@gmail.com> [ The deadlock scenario has been discovered by Andreas Mohr ] I think I might have a logical explanation why the system: (http://bugzilla.kernel.org/show_bug.cgi?id=12100) might hang upon resuming, OTOH it should have likely hanged each and every time. (1) possible deadlock in microcode_resume_cpu() if either 'if' section is taken; (2) now, I don't see it in spec. and can't experimentally verify it (newer ucodes don't seem to be available for my Core2duo)... but logically-wise, I'd think that when read upon resuming, the 'microcode revision' (MSR 0x8B) should be back to its original one (we need to reload ucode anyway so it doesn't seem logical if a cpu doesn't drop the version)... if so, the comparison with memcmp() for the full 'struct cpu_signature' is wrong... and that's how one of the aforementioned 'if' sections might have been triggered - leading to a deadlock. Obviously, in my tests I simulated loading/resuming with the ucode of the same version (just to see that the file is loaded/re-loaded upon resuming) so this issue has never popped up. I'd appreciate if someone with an appropriate system might give a try to the 2nd patch (titled "fix a comparison && deadlock..."). In any case, the deadlock situation is a must-have fix.

2008-12-19ACPI: fix 2.6.28 acpi.debug_level regressionBjorn Helgaas
acpi_early_init() was changed to over-write the cmdline param, making it really inconvenient to set debug flags at boot-time. Also, This sets the default level to "info", which is what all the ACPI drivers use. So to enable messages from drivers, you only have to supply the "layer" (a.k.a. "component"). For non-"info" ACPI core and ACPI interpreter messages, you have to supply both level and layer masks, as before.
