commit ffefb8ea upstream. The users of ore_check_io() expect the reported device (In case of error) to be indexed relative to the passed-in ore_components table, and not the logical dev index. This causes a crash inside objlayoutdriver in case of an IO error. Signed-off-by:

commit 49908a1b upstream. A update is made to the sched:sched_switch event that adds some logic to the first parameter of the __print_flags() that shows the state of tasks. This change cause perf to fail parsing the flags. A simple fix is needed to have the parser be able to process ops within the argument. Reported-by:

commit 10667136 upstream. The ICT code erroneously uses PAGE_SIZE. The bug is that PAGE_SIZE isn't necessarily 4096, so on such platforms this code will not work correctly as we'll try to attempt to read an index in the table that the device never wrote, it always has 4096-byte pages. Additionally, the manual alignment code here is unnecessary -- Documentation/DMA-API-HOWTO.txt states: The cpu return address and the DMA bus master address are both guaranteed to be aligned to the smallest PAGE_SIZE order which is greater than or equal to the requested size. This invariant exists (for example) to guarantee that if you allocate a chunk which is smaller than or equal to 64 kilobytes, the extent of the buffer you receive will not cross a 64K boundary. Just use appropriate new constants and get rid of the alignment code. Cc: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by:

commit 9a215e40 upstream. The driver everywhere uses max TID count as 9, which is wrong, it should be 8. I think the reason it uses 9 here is off-by-one confusion by whoever wrote this. We do use the value IWL_MAX_TID_COUNT for "not QoS/no TID" but that is completely correct even if it is 8 and not 9 since 0-7 are only valid. As a side effect, this fixes the following bug: Open BA session requested for 00:23:cd:16:8a:7e tid 8 ------------[ cut here ]------------ kernel BUG at drivers/net/wireless/iwlwifi/iwl-trans-pcie-int.h:350! ... when you do echo "tx start 8" > /sys/kernel/debug/ieee80211/*/*/*/*/agg_status Reported-by:

commit e214a0fe upstream. Userspace verbs multicast attach/detach operations on a QP are done while holding the rwsem of the QP for reading. That's not sufficient since a reader lock allows more than one reader to acquire the lock. However, multicast attach/detach does list manipulation that can corrupt the list if multiple threads run in parallel. Fix this by acquiring the rwsem as a writer to serialize attach/detach operations. Add idr_write_qp() and put_qp_write() to encapsulate this. This fixes oops seen when running applications that perform multicast joins/leaves. Reported by: Mike Dubman <miked@mellanox.com> Signed-off-by:

commit e4f387d8 upstream. Unpaired calling of probe_hcall_entry and probe_hcall_exit might happen as following, which could cause incorrect preempt count. __trace_hcall_entry => trace_hcall_entry -> probe_hcall_entry => get_cpu_var => preempt_disable __trace_hcall_exit => trace_hcall_exit -> probe_hcall_exit => put_cpu_var => preempt_enable where: A => B and A -> B means A calls B, but => means A will call B through function name, and B will definitely be called. -> means A will call B through function pointer, so B might not be called if the function pointer is not set. So error happens when only one of probe_hcall_entry and probe_hcall_exit get called during a hcall. This patch tries to move the preempt count operations from probe_hcall_entry and probe_hcall_exit to its callers. Reported-by:

commit 37fb9a02 upstream. When re-enabling interrupts we have code to handle edge sensitive decrementers by resetting the decrementer to 1 whenever it is negative. If interrupts were disabled long enough that the decrementer wrapped to positive we do nothing. This means interrupts can be delayed for a long time until it finally goes negative again. While we hope interrupts are never be disabled long enough for the decrementer to go positive, we have a very good test team that can drive any kernel into the ground. The softlockup data we get back from these fails could be seconds in the future, completely missing the cause of the lockup. We already keep track of the timebase of the next event so use that to work out if we should trigger a decrementer exception. Signed-off-by:

The first is in _internal_start_scan, when we queue up a scan; we first queue the worker, and then set priv->scan_req. There's theoretically a 50mS delay which should be plenty, but doing things that way just seems racy (and not in the good way). The second is in the scan worker thread itself. Depending on the state of priv->scan_channel, we cancel pending scan runs and then requeue a run in 300mS. We then send the scan command down to the hardware, sleep, and if we get scan results for all the desired channels, we set priv->scan_req to NULL. However, it that's happened in less than 300mS, what happens with the pending scan run? This patch addresses both of those concerns. With the patch applied, we have not seen the oops in the past two weeks. Signed-off-by:

commit 1bb0b7d2 upstream. When using a >8bpp framebuffer, offb advertises truecolor, not directcolor, and doesn't touch the color map even if it has a corresponding access method for the real hardware. Thus it needs to set the pseudo-palette with all 3 components of the color, like other truecolor framebuffers, not with copies of the color index like a directcolor framebuffer would do. This went unnoticed for a long time because it's pretty hard to get offb to kick in with anything but 8bpp (old BootX under MacOS will do that and qemu does it). Signed-off-by:

commit eea915bb upstream. This oops was reported recently: firmware_loading_store+0xf9/0x17b dev_attr_store+0x20/0x22 sysfs_write_file+0x101/0x134 vfs_write+0xac/0xf3 sys_write+0x4a/0x6e system_call_fastpath+0x16/0x1b The complete backtrace was unfortunately not captured, but details can be found here: https://bugzilla.redhat.com/show_bug.cgi?id=769920 The cause is fairly clear. Its caused by the fact that firmware_loading_store has a case 0 in its switch statement that reads and writes the fw_priv->fw poniter without the protection of the fw_lock mutex. since there is a window between the time that _request_firmware sets fw_priv->fw to NULL and the time the corresponding sysfs file is unregistered, its possible for a user space application to race in, and write a zero to the loading file, causing a NULL dereference in firmware_loading_store. Fix it by extending the protection of the fw_lock mutex to cover all of the firware_loading_store function. Signed-off-by:

This is the temporary simple fix for 3.2, we need more changes in this area. 1. do_signal_stop() assumes that the running untraced thread in the stopped thread group is not possible. This was our goal but it is not yet achieved: a stopped-but-resumed tracee can clone the running thread which can initiate another group-stop. Remove WARN_ON_ONCE(!current->ptrace). 2. A new thread always starts with ->jobctl = 0. If it is auto-attached and this group is stopped, __ptrace_unlink() sets JOBCTL_STOP_PENDING but JOBCTL_STOP_SIGMASK part is zero, this triggers WANR_ON(!signr) in do_jobctl_trap() if another debugger attaches. Change __ptrace_unlink() to set the artificial SIGSTOP for report. Alternatively we could change ptrace_init_task() to copy signr from current, but this means we can copy it for no reason and hide the possible similar problems. Acked-by:

Test-case: int main(void) { int pid, status; pid = fork(); if (!pid) { for (;;) { if (!fork()) return 0; if (waitpid(-1, &status, 0) < 0) { printf("ERR!! wait: %m\n"); return 0; } } } assert(ptrace(PTRACE_ATTACH, pid, 0,0) == 0); assert(waitpid(-1, NULL, 0) == pid); assert(ptrace(PTRACE_SETOPTIONS, pid, 0, PTRACE_O_TRACEFORK) == 0); do { ptrace(PTRACE_CONT, pid, 0, 0); pid = waitpid(-1, NULL, 0); } while (pid > 0); return 1; } It fails because ->real_parent sees its child in EXIT_DEAD state while the tracer is going to change the state back to EXIT_ZOMBIE in wait_task_zombie(). The offending commit is 823b018e which moved the EXIT_DEAD check, but in fact we should not blame it. The original code was not correct as well because it didn't take ptrace_reparented() into account and because we can't really trust ->ptrace. This patch adds the additional check to close this particular race but it doesn't solve the whole problem. We simply can't rely on ->ptrace in this case, it can be cleared if the tracer is multithreaded by the exiting ->parent. I think we should kill EXIT_DEAD altogether, we should always remove the soon-to-be-reaped child from ->children or at least we should never do the DEAD->ZOMBIE transition. But this is too complex for 3.2. Reported-and-tested-by:Denys Vlasenko <vda.linux@googlemail.com> Tested-by:

This reverts commit 93b2ec01. The call to "schedule_work()" in rtc_initialize_alarm() happens too early, and can cause oopses at bootup Neil Brown explains why we do it: "If you set an alarm in the future, then shutdown and boot again after that time, then you will end up with a timer_queue node which is in the past. When this happens the queue gets stuck. That entry-in-the-past won't get removed until and interrupt happens and an interrupt won't happen because the RTC only triggers an interrupt when the alarm is "now". So you'll find that e.g. "hwclock" will always tell you that 'select' timed out. So we force the interrupt work to happen at the start just in case." and has a patch that convert it to do things in-process rather than with the worker thread, but right now it's too late to play around with this, so we just revert the patch that caused problems for now.

Turned out the ntlmv2 (default security authentication) upgrade was harder to test than expected, and we ran out of time to test against Apple and a few other servers that we wanted to. Delay upgrade of default security from ntlm to ntlmv2 (on mount) to 3.3. Still works fine to specify it explicitly via "sec=ntlmv2" so this should be fine. Acked-by:

The current check looks to see if the RFC1002 length is larger than CIFSMaxBufSize, and fails if it is. The buffer is actually larger than that by MAX_CIFS_HDR_SIZE. This bug has been around for a long time, but the fact that we used to cap the clients MaxBufferSize at the same level as the server tended to paper over it. Commit c974befa changed that however and caused this bug to bite in more cases. Reported-and-Tested-by:

Commit 1e39f384 ("evm: fix build problems") makes the stub version of security_old_inode_init_security() return 0 when CONFIG_SECURITY is not set. But that makes callers such as reiserfs_security_init() assume that security_old_inode_init_security() has set name, value, and len arguments properly - but security_old_inode_init_security() left them uninitialized which then results in interesting failures. Revert security_old_inode_init_security() to the old behavior of returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this just fine. [ Also fixed the S_PRIVATE(inode) case of the actual non-stub security_old_inode_init_security() function to return EOPNOTSUPP for the same reason, as pointed out by Mimi Zohar. It got incorrectly changed to match the new function in commit fb88c2b6: "evm: fix security/security_old_init_security return code". - Linus ] Reported-by:

However, Kconfig uses the broader ARCH_MXS symbol and this way even makes the fec-driver default for MX23. Adapt Kconfig to use the more precise SOC_IMX28 as well. Signed-off-by:

grp->slot_shift is between 22 and 41, so using 32bit wide variables is probably a typo. This could explain QFQ hangs Dave reported to me, after 2^23 packets ? (23 = 64 - 41) Reported-by:
