commit ef2b1d77 upstream. The atlas7 clock controller driver registers a reset controller for itself, which causes a link error when the subsystem is disabled: drivers/built-in.o: In function `atlas7_clk_init': drivers/clk/sirf/clk-atlas7.c:1681: undefined reference to `reset_controller_register' As the clk driver does not have a Kconfig symbol for itself but it always built-in when the platform is enabled, we have to ensure that the reset controller subsystem is also built-in in this case.

commit eee57723 upstream. When un-mapping skb->data in __bcmgenet_tx_reclaim(), we must use the length that was used in original dma_map_single(), instead of skb->len that might be bigger (includes the frags) We simply can store skb_len into tx_cb_ptr->dma_len and use it at unmap time.

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: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Kamal Mostafa <kamal@canonical.com>

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 d57019d1 upstream. The driver of course "knows" that the chip's reset signal is active low, so it drives the GPIO to 0 to reset the PHY and to 1 otherwise; however all this will only work iff the GPIO is specified as active-high in the device tree! I think both the driver and the device trees (if there are any -- I was unable to find them) need to be fixed in this case...

commit d321cd01 upstream. When joining IBSS a full scan should be initiated in order to search for existing cell, unless the fixed_channel parameter was set. A default channel to create the IBSS on if no cell was found is provided as well. However - a scan is initiated only on the default channel provided regardless of whether ifibss->fixed_channel is set or not, with the obvious result of the cell not joining existing IBSS cell that is on another channel.

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 cdc4e47d upstream. Lots of places in the kernel use memcpy(buf, comm, TASK_COMM_LEN); but the result is typically passed to print("%s", buf) and extra bytes after zero don't cause any harm. In bpf the result of bpf_get_current_comm() is used as the part of map key and was causing spurious hash map mismatches. Use strlcpy() to guarantee zero-terminated string. bpf verifier checks that output buffer is zero-initialized, so even for short task names the output buffer don't have junk bytes. Note it's not a security concern, since kprobe+bpf is root only.

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.

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.

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.

commit 8134233e upstream. If the call to acpi_get_object_info() fails then "info" hasn't been initialized.

commit 7617a24f upstream. The IPVS SIP persistence engine is not able to parse the SIP header "Call-ID" when such header is inserted in the first positions of the SIP message. When IPVS is configured with "--pe sip" option, like for example: ipvsadm -A -u 1.2.3.4:5060 -s rr --pe sip -p 120 -o some particular messages (see below for details) do not create entries in the connection template table, which can be listed with: ipvsadm -Lcn --persistent-conn Problematic SIP messages are SIP responses having "Call-ID" header positioned just after message first line: SIP/2.0 200 OK [Call-ID header here] [rest of the headers] When "Call-ID" header is positioned down (after a few other headers) it is correctly recognized. This is due to the data offset used in get_callid function call inside ip_vs_pe_sip.c file: since dptr already points to the start of the SIP message, the value of dataoff should be initially 0. Otherwise the header is searched starting from some bytes after the first character of the SIP message.
