2020-11-16media: v4l2-fwnode: Say it's fine to use v4l2_fwnode_endpoint_parseSakari Ailus
Earlier it was expected that there would be more variable size endpoint properties and that most if not all drivers would need them. For that reason it was expected also that v4l2_fwnode_endpoint_parse would no longer be needed. What actually happened that not all drivers require "link-frequencies", the only variable size media endpoint property without a small upper limit. Therefore drivers that do not need that information are fine using v4l2_fwnode_endpoint_parse. So don't tell drivers to use v4l2_fwnode_endpoint_alloc_parse in all cases.

2020-11-16media: Fix V4L2_COLORSPACE_470_SYSTEM_BG descriptionHans Verkuil
The description of the V4L2_COLORSPACE_470_SYSTEM_BG stated that it was superseded by SMPTE 170M. That is incorrect. The probably root cause of this is that the HDMI standard does not support this colorspace and, unless otherwise signaled, will fall back to SMPTE 170M for SDTV. However, EBU Tech. 3321 states that sources should signal Rec. 709 as the colorimetry when using HDMI since the difference between Rec. 709 and Tech. 3213 are negligible. Update the text accordingly. Also drop a spurious " at the end of the Tech 3213 title in the bibliography. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2020-11-16media: v4l2: allocate v4l2_clip objects earlyArnd Bergmann
The v4l2_format based ioctls can have an indirect pointer to an array of v4l2_clip structures for overlay mode, depending on the 'type' member. There are only five drivers that use the overlay mode and copy the data through the __user pointer. Change the five drivers to use memcpy() instead, and copy the data in common code using the check_array_args() helpers. This allows for a subsequent patch that use the same mechanism for compat ioctl handlers. Note that there is another pointer for a 'bitmap' that is only used in the 'vivid' driver and nowhere else. There is no easy way to use the same trick without adding complexity to the common code, so this remains a __user pointer.

2020-11-16media: v4l2: prepare compat-ioctl reworkArnd Bergmann
The v4l2-compat-ioctl32() currently takes an extra round trip through user space pointers when converting the data structure formats. In particular, this involves using the compat_alloc_user_space() and copy_in_user() helpers that often lead to worse compat handlers compared to using in_compat_syscall() checks when copying the data. The native implementation already gained a simpler method to deal with the conversion for the time32 conversion. Hook into the same places to provide a location for reading and writing user space data from inside of the generic video_usercopy() helper. Hans Verkuil rewrote the video_get_user() function here to simplify the zeroing of the extra input fields and fixed a couple of bugs in the original implementation.

Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless.

2020-10-24random32: add noise from network and scheduling activityWilly Tarreau
With the removal of the interrupt perturbations in previous random32 change (random32: make prandom_u32() output unpredictable), the PRNG has become 100% deterministic again. While SipHash is expected to be way more robust against brute force than the previous Tausworthe LFSR, there's still the risk that whoever has even one temporary access to the PRNG's internal state is able to predict all subsequent draws till the next reseed (roughly every minute). This may happen through a side channel attack or any data leak. This patch restores the spirit of commit f227e3ec3b5c ("random32: update the net random state on interrupt and activity") in that it will perturb the internal PRNG's statee using externally collected noise, except that it will not pick that noise from the random pool's bits nor upon interrupt, but will rather combine a few elements along the Tx path that are collectively hard to predict, such as dev, skb and txq pointers, packet length and jiffies values. These ones are combined using a single round of SipHash into a single long variable that is mixed with the net_rand_state upon each invocation. The operation was inlined because it produces very small and efficient code, typically 3 xor, 2 add and 2 rol. The performance was measured to be the same (even very slightly better) than before the switch to SipHash; on a 6-core 12-thread Core i7-8700k equipped with a 40G NIC (i40e), the connection rate dropped from 556k/s to 555k/s while the SYN cookie rate grew from 5.38 Mpps to 5.45 Mpps.

2020-10-24random32: make prandom_u32() output unpredictableGeorge Spelvin
Non-cryptographic PRNGs may have great statistical properties, but are usually trivially predictable to someone who knows the algorithm, given a small sample of their output. An LFSR like prandom_u32() is particularly simple, even if the sample is widely scattered bits. It turns out the network stack uses prandom_u32() for some things like random port numbers which it would prefer are *not* trivially predictable. Predictability led to a practical DNS spoofing attack. Oops. This patch replaces the LFSR with a homebrew cryptographic PRNG based on the SipHash round function, which is in turn seeded with 128 bits of strong random key. (The authors of SipHash have *not* been consulted about this abuse of their algorithm.) Speed is prioritized over security; attacks are rare, while performance is always wanted. Replacing all callers of prandom_u32() is the quick fix. Whether to reinstate a weaker PRNG for uses which can tolerate it is an open question. Commit f227e3ec3b5c ("random32: update the net random state on interrupt and activity") was an earlier attempt at a solution. This patch replaces it.

2020-10-22hil/parisc: Disable HIL driver when it gets stuckHelge Deller
When starting a HP machine with HIL driver but without an HIL keyboard or HIL mouse attached, it may happen that data written to the HIL loop gets stuck (e.g. because the transaction queue is full). Usually one will then have to reboot the machine because all you see is and endless output of: Transaction add failed: transaction already queued? In the higher layers hp_sdc_enqueue_transaction() is called to queued up a HIL packet. This function returns an error code, and this patch adds the necessary checks for this return code and disables the HIL driver if further packets can't be sent. Tested on a HP 730 and a HP 715/64 machine. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org>

Clean this up and change the internal helper that io_uring uses to deal with kernel pointers instead. This puts the offset copy in/out in __do_splice() instead, which just calls the same helper.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This contains no changes to the core framework. It is a collection of various clk driver updates. The biggest driver updates in terms of lines of code is the Allwinner driver, closely followed by the Qualcomm and Mediatek drivers. All of those hit high because we add so many lines of clk data. Coming in fourth place is i.MX which also adds a bunch of clk data. This accounts for the new driver additions this time around. Otherwise the patches are lots of little cleanups and fixes for various clk drivers that have baked in linux-next for a while. I suppose one highlight or theme is that more clk drivers are being updated to work as modules, which is interesting to see such critical SoC infrastructure work as a loadable module. New Drivers: - Support qcom SM8150/SM8250 video and display clks - Support Mediatek MT8167 clks - Add clock for CRC block found on vf610 SoCs - Add support for the Renesas R-Car V3U (R8A779A0) SoC - Add support for the VSP for Resizing clock on Renesas RZ/G1H - Support Allwinner A100 SoC clks Removed Drivers: - Remove i.MX21 clock driver, as i.MX21 platform support is being dropped Updates: - Change how qcom's display port clks work - Small non-critical fixes for TI clk driver - Remove various unused variables in clk drivers - Allow Rockchip clk driver to be a module - Remove most __clk_lookup() calls in Samsung drivers (yay!) - Support building i.MX ARMv8 platforms clock driver as module - Some kerneldoc fixes here and there - A couple of minor i.MX clk data corrections - Update audio clock inverter and fdiv2 flag on Amlogic g12 - Make amlogic clk drivers configurable in Kconfig - Fix Renesas VSP clock names to match corrected hardware documentation - Sigma-delta modulation on Allwinner R40 - Various fixes for at91 clk driver - Use semicolons instead of commas in some places - Mark some variables const so they can move to RO memory" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (102 commits) clk: imx8mq: Fix usdhc parents order clk: qcom: gdsc: Keep RETAIN_FF bit set if gdsc is already on clk: Restrict CLK_HSDK to ARC_SOC_HSDK clk: at91: sam9x60: support only two programmable clocks clk: ingenic: Respect CLK_SET_RATE_PARENT in .round_rate clk: ingenic: Don't tag custom clocks with CLK_SET_RATE_PARENT clk: ingenic: Don't use CLK_SET_RATE_GATE for PLL clk: ingenic: Use readl_poll_timeout instead of custom loop clk: ingenic: Use to_clk_info() macro for all clocks clk: bcm2835: add missing release if devm_clk_hw_register fails clk: at91: clk-sam9x60-pll: remove unused variable clk: at91: clk-main: update key before writing AT91_CKGR_MOR clk: at91: remove the checking of parent_name clk: clk-prima2: fix return value check in prima2_clk_init() clk: mmp2: Fix the display clock divider base clk: pxa: Constify static struct clk_ops clk: baikal-t1: Mark Ethernet PLL as critical clk: qoriq: modify MAX_PLL_DIV to 32 clk: axi-clkgen: Set power bits for fractional mode clk: axi-clkgen: Add support for fractional dividers ...
