2022-06-22usb: cdnsp: Fixed setting last_trb incorrectlyJing Leng1-8/+11
commit 5c7578c39c3fffe85b7d15ca1cf8cf7ac38ec0c1 upstream. When ZLP occurs in bulk transmission, currently cdnsp will set last_trb for the last two TRBs, it will trigger an error "ERROR Transfer event TRB DMA ptr not part of current TD ...".

commit 242439f7e279d86b3f73b5de724bc67b2f8aeb07 upstream. The expression for setting the size of the allocated bulk TX buffer (`devpriv->usb_tx_buf`) is calling `usb_endpoint_maxp(devpriv->ep_rx)`, which is using the wrong endpoint (should be `devpriv->ep_tx`).

2022-06-22i2c: designware: Use standard optional ref clock implementationSerge Semin2-5/+11
[ Upstream commit 27071b5cbca59d8e8f8750c199a6cbf8c9799963 ] Even though the DW I2C controller reference clock source is requested by the method devm_clk_get() with non-optional clock requirement the way the clock handler is used afterwards has a pure optional clock semantic (though in some circumstances we can get a warning about the clock missing printed in the system console). There is no point in reimplementing that functionality seeing the kernel clock framework already supports the optional interface from scratch. Thus let's convert the platform driver to using it. Note by providing this commit we get to fix two problems. The first one was introduced in commit c62ebb3d5f0d ("i2c: designware: Add support for an interface clock"). It causes not having the interface clock (pclk) enabled/disabled in case if the reference clock isn't provided. The second problem was first introduced in commit b33af11de236 ("i2c: designware: Do not require clock when SSCN and FFCN are provided"). Since that modification the deferred probe procedure has been unsupported in case if the interface clock isn't ready.

2022-06-22net: remove noblock parameter from skb_recv_datagram()Oliver Hartkopp2-3/+2
[ Upstream commit f4b41f062c424209e3939a81e6da022e049a45f2 ] skb_recv_datagram() has two parameters 'flags' and 'noblock' that are merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)' As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags' into 'flags' and 'noblock' with finally obsolete bit operations like this: skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc); And this is not even done consistently with the 'flags' parameter. This patch removes the obsolete and costly splitting into two parameters and only performs bit operations when really needed on the caller side.

2022-06-22ice: Fix queue config fail handlingPrzemyslaw Patynowski1-27/+26
[ Upstream commit be2af71496a54a7195ac62caba6fab49cfe5006c ] Disable VF's RX/TX queues, when VIRTCHNL_OP_CONFIG_VSI_QUEUES fail. Not disabling them might lead to scenario, where PF driver leaves VF queues enabled, when VF's VSI failed queue config. In this scenario VF should not have RX/TX queues enabled. If PF failed to set up VF's queues, VF will reset due to TX timeouts in VF driver. Initialize iterator 'i' to -1, so if error happens prior to configuring queues then error path code will not disable queue 0. Loop that configures queues will is using same iterator, so error path code will only disable queues that were configured.

[ Upstream commit 71a579f0d3777a704355e6f1572dfba92a9b58b2 ] The offset was being incorrectly calculated for E822 - that led to collisions in choosing TX timestamp register location when more than one port was trying to use timestamping mechanism. In E822 one quad is being logically split between ports, so quad 0 is having trackers for ports 0-3, quad 1 ports 4-7 etc. Each port should have separate memory location for tracking timestamps. Due to error for example ports 1 and 2 had been assigned to quad 0 with same offset (0), while port 1 should have offset 0 and 1 offset 16. Fix it by correctly calculating quad offset.

[ Upstream commit 4b7a632ac4e7101ceefee8484d5c2ca505d347b3 ] Both RIF and ACL flow counters use a 24-bit SW-managed counter address to communicate which counter they want to bind. In a number of Spectrum FW releases, binding a RIF counter is broken and slices the counter index to 16 bits. As a result, on Spectrum-2 and above, no more than about 410 RIF counters can be effectively used. This translates to 205 netdevices for which L3 HW stats can be enabled. (This does not happen on Spectrum-1, because there are fewer counters available overall and the counter index never exceeds 16 bits.) Binding counters to ACLs does not have this issue. Therefore reorder the counter allocation scheme so that RIF counters come first and therefore get lower indices that are below the 16-bit barrier.

2022-06-22random: credit cpu and bootloader seeds by defaultJason A. Donenfeld1-19/+31
[ Upstream commit 846bb97e131d7938847963cca00657c995b1fce1 ] This commit changes the default Kconfig values of RANDOM_TRUST_CPU and RANDOM_TRUST_BOOTLOADER to be Y by default. It does not change any existing configs or change any kernel behavior. The reason for this is several fold. As background, I recently had an email thread with the kernel maintainers of Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void as recipients. I noted that some distros trust RDRAND, some trust EFI, and some trust both, and I asked why or why not. There wasn't really much of a "debate" but rather an interesting discussion of what the historical reasons have been for this, and it came up that some distros just missed the introduction of the bootloader Kconfig knob, while another didn't want to enable it until there was a boot time switch to turn it off for more concerned users (which has since been added). The result of the rather uneventful discussion is that every major Linux distro enables these two options by default. While I didn't have really too strong of an opinion going into this thread -- and I mostly wanted to learn what the distros' thinking was one way or another -- ultimately I think their choice was a decent enough one for a default option (which can be disabled at boot time). I'll try to summarize the pros and cons: Pros: - The RNG machinery gets initialized super quickly, and there's no messing around with subsequent blocking behavior. - The bootloader mechanism is used by kexec in order for the prior kernel to initialize the RNG of the next kernel, which increases the entropy available to early boot daemons of the next kernel. - Previous objections related to backdoors centered around Dual_EC_DRBG-like kleptographic systems, in which observing some amount of the output stream enables an adversary holding the right key to determine the entire output stream. This used to be a partially justified concern, because RDRAND output was mixed into the output stream in varying ways, some of which may have lacked pre-image resistance (e.g. XOR or an LFSR). But this is no longer the case. Now, all usage of RDRAND and bootloader seeds go through a cryptographic hash function. This means that the CPU would have to compute a hash pre-image, which is not considered to be feasible (otherwise the hash function would be terribly broken). - More generally, if the CPU is backdoored, the RNG is probably not the realistic vector of choice for an attacker. - These CPU or bootloader seeds are far from being the only source of entropy. Rather, there is generally a pretty huge amount of entropy, not all of which is credited, especially on CPUs that support instructions like RDRAND. In other words, assuming RDRAND outputs all zeros, an attacker would *still* have to accurately model every single other entropy source also in use. - The RNG now reseeds itself quite rapidly during boot, starting at 2 seconds, then 4, then 8, then 16, and so forth, so that other sources of entropy get used without much delay. - Paranoid users can set random.trust_{cpu,bootloader}=no in the kernel command line, and paranoid system builders can set the Kconfig options to N, so there's no reduction or restriction of optionality. - It's a practical default. - All the distros have it set this way. Microsoft and Apple trust it too. Bandwagon. Cons: - RDRAND *could* still be backdoored with something like a fixed key or limited space serial number seed or another indexable scheme like that. (However, it's hard to imagine threat models where the CPU is backdoored like this, yet people are still okay making *any* computations with it or connecting it to networks, etc.) - RDRAND *could* be defective, rather than backdoored, and produce garbage that is in one way or another insufficient for crypto. - Suggesting a *reduction* in paranoia, as this commit effectively does, may cause some to question my personal integrity as a "security person". - Bootloader seeds and RDRAND are generally very difficult if not all together impossible to audit. Keep in mind that this doesn't actually change any behavior. This is just a change in the default Kconfig value. The distros already are shipping kernels that set things this way. Ard made an additional argument in [1]: We're at the mercy of firmware and micro-architecture anyway, given that we are also relying on it to ensure that every instruction in the kernel's executable image has been faithfully copied to memory, and that the CPU implements those instructions as documented. So I don't think firmware or ISA bugs related to RNGs deserve special treatment - if they are broken, we should quirk around them like we usually do. So enabling these by default is a step in the right direction IMHO. In [2], Phil pointed out that having this disabled masked a bug that CI otherwise would have caught: A clean 5.15.45 boots cleanly, whereas a downstream kernel shows the static key warning (but it does go on to boot). The significant difference is that our defconfigs set CONFIG_RANDOM_TRUST_BOOTLOADER=y defining that on top of multi_v7_defconfig demonstrates the issue on a clean 5.15.45. Conversely, not setting that option in a downstream kernel build avoids the warning [1] https://lore.kernel.org/lkml/CAMj1kXGi+ieviFjXv9zQBSaGyyzeGW_VpMpTLJK8PJb2QHEQ-w@mail.gmail.com/ [2] https://lore.kernel.org/lkml/c47c42e3-1d56-5859-a6ad-976a1a3381c6@raspberrypi.com/ Cc: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Jason A.
