2020-06-26mtd: rawnand: s/data_interface/interface_config/Miquel Raynal
The name/suffix data_interface is a bit misleading in that the field or functions actually represent a configuration that can be applied by the controller/chip. Let's rename all fields/functions/hooks that are worth renaming. Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2020-06-26mtd: rawnand: Hide the chip->data_interface indirectionMiquel Raynal
As a preparation for allocating the data interface structure dynamically (and rename it), let's avoid accessing chip->data_interface directly. Instead, we introduce a helper, nand_get_interface_config(), and use it to retrieve the current data interface configuration out of a nand_chip object.

2020-06-26mtd: rawnand: Reorganize the nand_chip structureMiquel Raynal
Reorder fields in this structure and pack entries by theme: * The main descriptive structures * The data interface details * Bad block information * The device layout * Extra buffers matching the device layout * Internal values * External objects like the ECC controller, the ECC engine and a private data pointer. While at it, adapt the documentation style. I changed on purpose the description of @oob_poi which was weird.

2020-06-26mtd: nand: Rename a core structureMiquel Raynal
Prepare the migration to a generic ECC engine by renaming the nand_ecc_req structure into nand_ecc_props. This structure will be the base of a wider 'nand_ecc' structure. In nand_device, these properties are still named "eccreq" even if "eccprops" might be more descriptive. This is just a transition step, this field is being replaced very soon by a much wider structure. The impact of renaming this field would be huge compared to its interest.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net, they are: 1) Unaligned atomic access in ipset, from Russell King. 2) Missing module description, from Rob Gill. 3) Patches to fix a module unload causing NULL pointer dereference in xtables, from David Wilder. For the record, I posting here his cover letter explaining the problem: A crash happened on ppc64le when running ltp network tests triggered by "rmmod iptable_mangle". See previous discussion in this thread: https://lists.openwall.net/netdev/2020/06/03/161 . In the crash I found in iptable_mangle_hook() that state->net->ipv4.iptable_mangle=NULL causing a NULL pointer dereference. net->ipv4.iptable_mangle is set to NULL in +iptable_mangle_net_exit() and called when ip_mangle modules is unloaded. A rmmod task was found running in the crash dump. A 2nd crash showed the same problem when running "rmmod iptable_filter" (net->ipv4.iptable_filter=NULL). To fix this I added .pre_exit hook in all iptable_foo.c. The pre_exit will un-register the underlying hook and exit would do the table freeing. The netns core does an unconditional +synchronize_rcu after the pre_exit hooks insuring no packets are in flight that have picked up the pointer before completing the un-register. These patches include changes for both iptables and ip6tables. We tested this fix with ltp running iptables01.sh and iptables01.sh -6 a loop for 72 hours. 4) Add a selftest for conntrack helper assignment, from Florian Westphal. ==================== Signed-off-by: David S.

2020-06-25bpf: Do not allow btf_ctx_access with __int128 typesJohn Fastabend
To ensure btf_ctx_access() is safe the verifier checks that the BTF arg type is an int, enum, or pointer. When the function does the BTF arg lookup it uses the calculation 'arg = off / 8' using the fact that registers are 8B. This requires that the first arg is in the first reg, the second in the second, and so on. However, for __int128 the arg will consume two registers by default LLVM implementation. So this will cause the arg layout assumed by the 'arg = off / 8' calculation to be incorrect. Because __int128 is uncommon this patch applies the easiest fix and will force int types to be sizeof(u64) or smaller so that they will fit in a single register. v2: remove unneeded parens per Andrii's feedback Fixes: 9e15db66136a1 ("bpf: Implement accurate raw_tp context access via BTF") Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Andrii Nakryiko <andriin@fb.com> Link: https://lore.kernel.org/bpf/159303723962.11287.13309537171132420717.stgit@john-Precision-5820-Tower

All possible argument btf_id and return value btf_id for helper bpf_skc_to_tcp6_sock() are pre-calculcated and cached.

As Heiner pointed out "I was thinking about calling phy_disable_interrupts() in phy_init_hw(), to have a defined init state as we don't know in which state the PHY is if the PHY driver is loaded. We shouldn't assume that it's the chip power-on defaults, BIOS or boot loader could have changed this. Or in case of dual-boot systems the other OS could leave the PHY in whatever state."

2020-06-24net: phy: add support for a common probe between shared PHYsAntoine Tenart
Shared PHYs (PHYs in the same hardware package) may have shared registers and their drivers would usually need to share information. There is currently a way to have a shared (part of the) init, by using phy_package_init_once(). This patch extends the logic to share parts of the probe to allow sharing the initialization of locks or resources retrieval.

2020-06-24OPP: refactor dev_pm_opp_of_register_em() and update related driversLukasz Luba
The Energy Model framework supports not only CPU devices. Drop the CPU specific interface with cpumask and add struct device. Add also a return value, user might use it. This new interface provides easy way to create a simple Energy Model, which then might be used by e.g. thermal subsystem.

2020-06-24PM / EM: change name of em_pd_energy to em_cpu_energyLukasz Luba
Energy Model framework now supports other devices than CPUs. Refactor some of the functions in order to prevent wrong usage. The old function em_pd_energy has to generic name. It must not be used without proper cpumask pointer, which is possible only for CPU devices. Thus, rename it and add proper description to warn of potential wrong usage for other devices.

2020-06-24PM / EM: add support for other devices than CPUs in Energy ModelLukasz Luba
Add support for other devices than CPUs. The registration function does not require a valid cpumask pointer and is ready to handle new devices. Some of the internal structures has been reorganized in order to keep consistent view (like removing per_cpu pd pointers). Signed-off-by: Lukasz Luba <lukasz.luba@arm.com> Signed-off-by: Rafael J.
