commit 08a5bb29 upstream. hugepd_free() used __get_cpu_var() once. Nothing ensured that the code accessing the variable did not migrate from one CPU to another and soon this was noticed by Tiejun Chen in 94b09d75 ("powerpc/hugetlb: Replace __get_cpu_var with get_cpu_var"). So we had it fixed. Christoph Lameter was doing his __get_cpu_var() replaces and forgot PowerPC. Then he noticed this and sent his fixed up batch again which got applied as 69111bac ("powerpc: Replace __get_cpu_var uses"). The careful reader will noticed one little detail: get_cpu_var() got replaced with this_cpu_ptr(). So now we have a put_cpu_var() which does a preempt_enable() and nothing that does preempt_disable() so we underflow the preempt counter.

commit e5435891 upstream. Despite what the DocBook comment to pkcs7_validate_trust() says, the *_trusted argument is never set to false. pkcs7_validate_trust() only positively sets *_trusted upon encountering a trusted PKCS#7 SignedInfo block. This is quite unfortunate since its callers, system_verify_data() for example, depend on pkcs7_validate_trust() clearing *_trusted on non-trust. Indeed, UBSAN splats when attempting to load the uninitialized local variable 'trusted' from system_verify_data() in pkcs7_validate_trust(): UBSAN: Undefined behaviour in crypto/asymmetric_keys/pkcs7_trust.c:194:14 load of value 82 is not a valid value for type '_Bool' [...] Call Trace: [<ffffffff818c4d35>] dump_stack+0xbc/0x117 [<ffffffff818c4c79>] ? _atomic_dec_and_lock+0x169/0x169 [<ffffffff8194113b>] ubsan_epilogue+0xd/0x4e [<ffffffff819419fa>] __ubsan_handle_load_invalid_value+0x111/0x158 [<ffffffff819418e9>] ? val_to_string.constprop.12+0xcf/0xcf [<ffffffff818334a4>] ? x509_request_asymmetric_key+0x114/0x370 [<ffffffff814b83f0>] ? kfree+0x220/0x370 [<ffffffff818312c2>] ? public_key_verify_signature_2+0x32/0x50 [<ffffffff81835e04>] pkcs7_validate_trust+0x524/0x5f0 [<ffffffff813c391a>] system_verify_data+0xca/0x170 [<ffffffff813c3850>] ? top_trace_array+0x9b/0x9b [<ffffffff81510b29>] ? __vfs_read+0x279/0x3d0 [<ffffffff8129372f>] mod_verify_sig+0x1ff/0x290 [...] The implication is that pkcs7_validate_trust() effectively grants trust when it really shouldn't have. Fix this by explicitly setting *_trusted to false at the very beginning of pkcs7_validate_trust(). Signed-off-by:

commit b7a58459 upstream. On Xen PV, regs->flags doesn't reliably reflect IOPL and the exit-to-userspace code doesn't change IOPL. We need to context switch it manually. I'm doing this without going through paravirt because this is specific to Xen PV. After the dust settles, we can merge this with the 32-bit code, tidy up the iopl syscall implementation, and remove the set_iopl pvop entirely. Fixes XSA-171. Reviewewd-by:

commit fb166ba1 upstream. The regmap_irq_get_virq() can return 0 or -EINVAL in error conditions but driver checked only for value of 0. This could lead to a cast of -EINVAL to an unsigned int used as a interrupt number for devm_request_threaded_irq(). Although this is not yet fatal (devm_request_threaded_irq() will just fail with -EINVAL) but might be a misleading when diagnosing errors. Signed-off-by:

commit ec7957a6 upstream. Despite care take to allocate clocks state containers the SP810 driver actually just supports creating one instance: all clocks registered for every instance will end up with the exact same name and __clk_init() will fail. Rename the timclken<0> .. timclken<n> to sp810_<instance>_<n> so every clock on every instance gets a unique name. This is necessary for the RealView PBA8 which has two SP810 blocks: the second block will not register its clocks unless every clock on every instance is unique and results in boot logs like this: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at ../drivers/clk/versatile/clk-sp810.c:137 clk_sp810_of_setup+0x110/0x154() Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.5.0-rc2-00030-g352718fc39f6-dirty #225 Hardware name: ARM RealView Machine (Device Tree Support) [<c00167f8>] (unwind_backtrace) from [<c0013204>] (show_stack+0x10/0x14) [<c0013204>] (show_stack) from [<c01a049c>] (dump_stack+0x84/0x9c) [<c01a049c>] (dump_stack) from [<c0024990>] (warn_slowpath_common+0x74/0xb0) [<c0024990>] (warn_slowpath_common) from [<c0024a68>] (warn_slowpath_null+0x1c/0x24) [<c0024a68>] (warn_slowpath_null) from [<c051eb44>] (clk_sp810_of_setup+0x110/0x154) [<c051eb44>] (clk_sp810_of_setup) from [<c051e3a4>] (of_clk_init+0x12c/0x1c8) [<c051e3a4>] (of_clk_init) from [<c0504714>] (time_init+0x20/0x2c) [<c0504714>] (time_init) from [<c0501b18>] (start_kernel+0x244/0x3c4) [<c0501b18>] (start_kernel) from [<7000807c>] (0x7000807c) ---[ end trace cb88537fdc8fa200 ]--- Cc: Michael Turquette <mturquette@baylibre.com> Cc: Pawel Moll <pawel.moll@arm.com> Fixes: 6e973d2c "clk: vexpress: Add separate SP810 driver" Signed-off-by:

commit e8e56ffd upstream. Locking ppp_mutex must be done before dereferencing file->private_data, otherwise it could be modified before ppp_unattached_ioctl() takes the lock. This could lead ppp_unattached_ioctl() to override ->private_data, thus leaking reference to the ppp_file previously pointed to. v2: lock all ppp_ioctl() instead of just checking private_data in ppp_unattached_ioctl(), to avoid ambiguous behaviour.

commit e07ff943 upstream. The s5m8767_pmic_probe() function calls s5m8767_get_register() to read data without checking the return code, which produces a compile-time warning when that data is accessed: drivers/regulator/s5m8767.c: In function 's5m8767_pmic_probe': drivers/regulator/s5m8767.c:924:7: error: 'enable_reg' may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/regulator/s5m8767.c:944:30: error: 'enable_val' may be used uninitialized in this function [-Werror=maybe-uninitialized] This changes the s5m8767_get_register() function to return a -EINVAL not just for an invalid register number but also for an invalid regulator number, as both would result in returning uninitialized data. The s5m8767_pmic_probe() function is then changed accordingly to fail on a read error, as all the other callers of s5m8767_get_register() already do. In practice this probably cannot happen, as we don't call s5m8767_get_register() with invalid arguments, but the gcc warning seems valid in principle, in terms writing safe error checking.

commit dec63a4d upstream. gcc-6.0 found an ancient bug in the paride driver, which had a "module_param(verbose, bool, 0);" since before 2.6.12, but actually uses it to accept '0', '1' or '2' as arguments: drivers/block/paride/pd.c: In function 'pd_init_dev_parms': drivers/block/paride/pd.c:298:29: warning: comparison of constant '1' with boolean expression is always false [-Wbool-compare] #define DBMSG(msg) ((verbose>1)?(msg):NULL) In 2012, Rusty did a cleanup patch that also changed the type of the variable to 'bool', which introduced what is now a gcc warning. This changes the type back to 'int' and adapts the module_param() line instead, so it should work as documented in case anyone ever cares about running the ancient driver with debugging.

commit da6ccaaa upstream. Make the "Attempted send on closed socket" error messages generated in nbd_request_handler() ratelimited. When the nbd socket is shutdown, the nbd_request_handler() function emits an error message for every request remaining in its queue. If the queue is large, this will spam a large amount of messages to the log. There's no need for a separate error message for each request, so this patch ratelimits it. In the specific case this was found, the system was virtual and the error messages were logged to the serial port, which overwhelmed it.

commit cf440128 upstream. The ieee80211_queue_stopped() expects hw queue number but it was given raw WMM AC number instead. This could cause frame drops and problems with traffic in some cases - most notably if driver doesn't map AC numbers to queue numbers 1:1 and uses ieee80211_stop_queues() and ieee80211_wake_queue() only without ever calling ieee80211_wake_queues(). On ath10k it was possible to hit this problem in the following case: 1. wlan0 uses queue 0 (ath10k maps queues per vif) 2. offchannel uses queue 15 3. queues 1-14 are unused 4. ieee80211_stop_queues() 5. ieee80211_wake_queue(q=0) 6. ieee80211_wake_queue(q=15) (other queues are not woken up because both driver and mac80211 know other queues are unused) 7. ieee80211_rx_h_mesh_fwding() 8. ieee80211_select_queue_80211() returns 2 9. ieee80211_queue_stopped(q=2) returns true 10. frame is dropped (oops!)

commit c8b08ca5 upstream. mkspec is copying built kernel to temporrary location /boot/vmlinuz-$KERNELRELEASE-rpm and runs installkernel on it. This however directly leads to grub2 menuentry for this suffixed binary being generated as well during the run of installkernel script. Later in the process the temporary -rpm suffixed files are removed, and therefore we end up with spurious (and non-functional) grub2 menu entries for each installed kernel RPM. Fix that by using a different temporary name (prefixed by '.'), so that the binary is not recognized as an actual kernel binary and no menuentry is created for it. Signed-off-by:

So let's delay the "cache_get" until we know we need it. Fixes: f9e1aedc ("sunrpc/cache: remove races with queuing an upcall.") Signed-off-by:

commit 9c6672ac upstream. Commit 6d80dba1 ("efi: Provide a non-blocking SetVariable() operation") implemented a non-blocking alternative for the UEFI SetVariable() invocation performed by efivars, since it may occur in atomic context. However, this version of the function was never exposed via the efivars struct, so the non-blocking versions was not actually callable. Fix that. Signed-off-by:

commit 98f42221 upstream. Based on CPU type choose generic omap3 or omap3430 specific cpuidle parameters. Parameters for omap3430 were measured on Nokia N900 device and added by commit 5a1b1d3a ("OMAP3: RX-51: Pass cpu idle parameters") which were later removed by commit 231900af ("ARM: OMAP3: cpuidle - remove rx51 cpuidle parameters table") due to huge code complexity. This patch brings cpuidle parameters for omap3430 devices again, but uses simple condition based on CPU type. Fixes: 231900af ("ARM: OMAP3: cpuidle - remove rx51 cpuidle parameters table") Signed-off-by:

commit 8e580411 upstream. The davinci platform has tried to get support for the EEPROM right, but failed to get a clean build so far. At the moment, we get a warning whenever CONFIG_SYSFS is disabled, as that is needed by EEPROM_AT24: warning: (MACH_DAVINCI_EVM && MACH_SFFSDR && MACH_DAVINCI_DM6467_EVM && MACH_DAVINCI_DM365_EVM && MACH_DAVINCI_DA830_EVM && MACH_MITYOMAPL138 && MACH_MINI2440) selects EEPROM_AT24 which has unmet direct dependencies (I2C && SYSFS) Kevin Hilman initially added the 'select' to ensure that EEPROM_AT24 is always enabled in machines that really want it for normal operation (i.e. for reading the MAC address). This broke when I2C was disabled, and Russell King followed up with another patch to select that as well. I now see that the SYSFS dependency is still missing, which leaves us with three options: a) add 'select SYSFS' in addition to the others b) change AT24_EEPPROM to work without sysfs (should be possible) c) remove all those selects again and get the files to build when I2C is disabled. I would really hate to do a) because adding select statements that hardwire user-selectable symbols is generally a bad idea. I first tried b) but then ended up redoing the patch from scratch to approach c), so we can also remove the other selects. I checked that CONFIG_I2C is still enabled with davinci_all_defconfig, so that does not have to change. Signed-off-by:

commit 83d6f1f1 upstream. Code that was added back in 2.6.38 has an obvious overflow when accessing a static array, and at the time it was added only a code comment was put in front of it as a reminder to have it reviewed properly. This has not happened, but gcc-6 now points to the specific overflow: drivers/net/wireless/ath/ath9k/eeprom.c: In function 'ath9k_hw_get_gain_boundaries_pdadcs': drivers/net/wireless/ath/ath9k/eeprom.c:483:44: error: array subscript is above array bounds [-Werror=array-bounds] maxPwrT4[i] = data_9287[idxL].pwrPdg[i][4]; ~~~~~~~~~~~~~~~~~~~~~~~~~^~~ It turns out that the correct array length exists in the local 'intercepts' variable of this function, so we can just use that instead of hardcoding '4', so this patch changes all three instances to use that variable. The other two instances were already correct, but it's more consistent this way. Signed-off-by:
