net: dst: introduce dst->dev_rcu

2025-12-18T12:55:22Z

[ Upstream commit caedcc5b6df1b2e2b5f39079e3369c1d4d5c5f50 ] Followup of commit 88fe14253e1818 ("net: dst: add four helpers to annotate data-races around dst->dev"). We want to gradually add explicit RCU protection to dst->dev, including lockdep support. Add an union to alias dst->dev_rcu and dst->dev. Add dst_dev_net_rcu() helper.

efi/cper: align ARM CPER type with UEFI 2.9A/2.10 specs

2025-12-18T12:55:21Z

[ Upstream commit 96b010536ee020e716d28d9b359a4bcd18800aeb ] Up to UEFI spec 2.9, the type byte of CPER struct for ARM processor was defined simply as: Type at byte offset 4: - Cache error - TLB Error - Bus Error - Micro-architectural Error All other values are reserved Yet, there was no information about how this would be encoded. Spec 2.9A errata corrected it by defining: - Bit 1 - Cache Error - Bit 2 - TLB Error - Bit 3 - Bus Error - Bit 4 - Micro-architectural Error All other values are reserved That actually aligns with the values already defined on older versions at N.2.4.1. Generic Processor Error Section. Spec 2.10 also preserve the same encoding as 2.9A. Adjust CPER and GHES handling code for both generic and ARM processors to properly handle UEFI 2.9A and 2.10 encoding.

efi/cper: Add a new helper function to print bitmasks

2025-12-18T12:55:21Z

[ Upstream commit a976d790f49499ccaa0f991788ad8ebf92e7fd5c ] Add a helper function to print a string with names associated to each bit field. A typical example is: const char * const bits[] = { "bit 3 name", "bit 4 name", "bit 5 name", }; char str[120]; unsigned int bitmask = BIT(3) | BIT(5); #define MASK GENMASK(5,3) cper_bits_to_str(str, sizeof(str), FIELD_GET(MASK, bitmask), bits, ARRAY_SIZE(bits)); The above code fills string "str" with "bit 3 name|bit 5 name".

nfs/vfs: discard d_exact_alias()

2025-12-18T12:55:17Z

[ Upstream commit 3ff6c8707c9a0116d00982851ec1216a42053ace ] d_exact_alias() is a descendent of d_add_unique() which was introduced 20 years ago mostly likely to work around problems with NFS servers of the time. It is now not used in several situations were it was originally needed and there have been no reports of problems - presumably the old NFS servers have been improved. This only place it is now use is in NFSv4 code and the old problematic servers are thought to have been v2/v3 only. There is no clear benefit in reusing a unhashed() dentry which happens to have the same name as the dentry we are adding. So this patch removes d_exact_alias() and the one place that it is used.

net: hsr: create an API to get hsr port type

2025-12-18T12:55:14Z

[ Upstream commit a0244e76213980f3b9bb5d40b0b6705fcf24230d ] Since the introduction of HSR_PT_INTERLINK in commit 5055cccfc2d1 ("net: hsr: Provide RedBox support (HSR-SAN)"), we see that different port types require different settings for hardware offload, which was not the case before when we only had HSR_PT_SLAVE_A and HSR_PT_SLAVE_B. But there is currently no way to know which port is which type, so create the hsr_get_port_type() API function and export it. When hsr_get_port_type() is called from the device driver, the port can must be found in the HSR port list. An important use case is for this function to work from offloading drivers' NETDEV_CHANGEUPPER handler, which is triggered by hsr_portdev_setup() -> netdev_master_upper_dev_link(). Therefore, we need to move the addition of the hsr_port to the HSR port list prior to calling hsr_portdev_setup(). This makes the error restoration path also more similar to hsr_del_port(), where kfree_rcu(port) is already used.
