Andy Shevchenko authoredcommit 9801ca27 upstream. Strangely I hadn't had noticed the existence of the list_entry_is_head() in apparmor code when added the same one in the list.h. Luckily it's fully identical and didn't break builds. In any case we don't need a duplicate anymore, thus remove it from apparmor code.

commit a8b92b8c upstream. We should not walk/touch page tables outside of VMA boundaries when holding only the mmap sem in read mode. Evil user space can modify the VMA layout just before this function runs and e.g., trigger races with page table removal code since commit dd2283f2 ("mm: mmap: zap pages with read mmap_sem in munmap"). find_vma() does not check if the address is >= the VMA start address; use vma_lookup() instead.

commit 3a2b2eb5 upstream. The Linux console's VT102 implementation already consumes OSC ("Operating System Command") sequences, probably because that's how palette changes are transmitted. In addition to OSC, there are three other major clases of ANSI control strings: APC ("Application Program Command"), PM ("Privacy Message"), and DCS ("Device Control String"). They are handled similarly to OSC in terms of termination. Source: vt100.net Add three new enumerated states, one for each of these types. All three are handled the same way right now--they simply consume input until terminated. I hope to expand upon this firmament in the future. Add new predicate ansi_control_string(), returning true for any of these states. Replace explicit checks against ESosc with calls to this function. Transition to these states appropriately from the escape initiation (ESesc) state. This was motivated by the following Notcurses bugs: https://github.com/dankamongmen/notcurses/issues/2050 https://github.com/dankamongmen/notcurses/issues/1828 https://github.com/dankamongmen/notcurses/issues/2069 where standard VT sequences are not consumed by the Linux console. It's not necessary that the Linux console *support* these sequences, but it ought *consume* these well-specified classes of sequences. Tested by sending a variety of escape sequences to the console, and verifying that they still worked, or were now properly consumed. Verified that the escapes were properly terminated at a generic level. Verified that the Notcurses tools continued to show expected output on the Linux console, except now without escape bleedthrough.

[ Upstream commit 8a0ed250 ] The GRE tunnel device can pull existing outer headers in ipge_xmit. This is a rare path, apparently unique to this device. The below commit ensured that pulling does not move skb->data beyond csum_start. But it has a false positive if ip_summed is not CHECKSUM_PARTIAL and thus csum_start is irrelevant. Refine to exclude this. At the same time simplify and strengthen the test. Simplify, by moving the check next to the offending pull, making it more self documenting and removing an unnecessary branch from other code paths. Strengthen, by also ensuring that the transport header is correct and therefore the inner headers will be after skb_reset_inner_headers. The transport header is set to csum_start in skb_partial_csum_set.

[ Upstream commit f949a9eb ] On Cherry Trail devices with an AXP288 PMIC the external SD-card slot used the AXP's DLDO2 as card-voltage and either DLDO3 or GPIO1LDO (GPIO1 pin in low noise LDO mode) as signal-voltage. These regulators are turned on/off and in case of the signal-voltage also have their output-voltage changed by the _PS0 and _PS3 power- management ACPI methods on the MMC-controllers ACPI fwnode as well as by the _DSM ACPI method for changing the signal voltage. The AML code implementing these methods is directly accessing the PMIC through ACPI I2C OpRegion accesses, instead of using the special PMIC OpRegion handled by drivers/acpi/pmic/intel_pmic_xpower.c . This means that the contents of the involved PMIC registers can change without the change being made through the regmap interface, so regmap should not cache the contents of these registers. Mark the regulator power on/off, the regulator voltage control and the GPIO1 control registers as volatile, to avoid regmap caching them. Specifically this fixes an issue on some models where the i915 driver toggles another LDO using the same on/off register on/off through MIPI sequences (through intel_soc_pmic_exec_mipi_pmic_seq_element()) which then writes back a cached on/off register-value where the card-voltage is off causing the external sdcard slot to stop working when the screen goes blank, or comes back on again. The regulator register-range now marked volatile also includes the buck regulator control registers. This is done on purpose these are normally not touched by the AML code, but they are updated directly by the SoC's PUNIT which means that they may also change without going through regmap. Note the AXP288 PMIC is only used on Bay- and Cherry-Trail platforms, so even though this is an ACPI specific problem there is no need to make the new volatile ranges conditional since these platforms always use ACPI. Fixes: dc91c3b6 ("mfd: axp20x: Mark AXP20X_VBUS_IPSOUT_MGMT as volatile") Fixes: cd532166 ("mfd: axp20x: Fix axp288 volatile ranges") Reported-and-tested-by:

[ Upstream commit 2d52c58b ] The function bfq_setup_merge prepares the merging between two bfq_queues, say bfqq and new_bfqq. To this goal, it assigns bfqq->new_bfqq = new_bfqq. Then, each time some I/O for bfqq arrives, the process that generated that I/O is disassociated from bfqq and associated with new_bfqq (merging is actually a redirection). In this respect, bfq_setup_merge increases new_bfqq->ref in advance, adding the number of processes that are expected to be associated with new_bfqq. Unfortunately, the stable-merging mechanism interferes with this setup. After bfqq->new_bfqq has been set by bfq_setup_merge, and before all the expected processes have been associated with bfqq->new_bfqq, bfqq may happen to be stably merged with a different queue than the current bfqq->new_bfqq. In this case, bfqq->new_bfqq gets changed. So, some of the processes that have been already accounted for in the ref counter of the previous new_bfqq will not be associated with that queue. This creates an unbalance, because those references will never be decremented. This commit fixes this issue by reestablishing the previous, natural behaviour: once bfqq->new_bfqq has been set, it will not be changed until all expected redirections have occurred. Signed-off-by:

[ Upstream commit d08c8b85 ] Root Ports in NXP LX2xx0 and LX2xx2, where each Root Port is a Root Complex with unique segment numbers, do provide isolation features to disable peer transactions and validate bus numbers in requests, but do not provide an actual PCIe ACS capability. Add ACS quirks for NXP LX2xx0 A/C/E/N and LX2xx2 A/C/E/N platforms.

[ Upstream commit ec343111 ] These are the actual frequencies reported by the PLL, so let's report these. The roundoffs are inappropriate, we should round to the frequency that the clock will later report. Drop some whitespace at the same time. Cc: phone-devel@vger.kernel.org Signed-off-by:
