To enable the wakealarm, the device must be able to wakeup. This is done by setting the device wakeup capability to true with 'device_init_wakeup' function. Signed-off-by: Mylène Josserand <mylene.josserand@free-electrons.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

Previous 'commit c3b79770 ("Expire alarms after the time is set")' and 'commit 48e97667 ("remove disabled alarm functionality")' removed the alarm support because the alarm irq was not functional. Add the alarm IRQ functionality with newer functions than previous code. Tested with 'rtctest' and the alarm is functional.

The driver used i2c_transfer methods to read and set date/time. The smbus methods should be used.

Many drivers are defining a DRV_VERSION. This is often only used for MODULE_VERSION and sometimes to print an info message at probe time. This is kind of pointless as they are all versionned with the kernel anyway. Also the core will print a message when a new rtc is found.

Original implementation commit e54bcde3 ("arm64: eBPF JIT compiler") had the relevant code paths, but due to an oversight always fail jiting. As a result, we had been falling back to BPF interpreter whenever a BPF program has JMP_JSET_{X,K} instructions. With this fix, we confirm that the corresponding tests in lib/test_bpf continue to pass, and also jited. ...

Paolo Abeni authored
Currently, when creating or updating a route, no check is performed in both ipv4 and ipv6 code to the hoplimit value. The caller can i.e. set hoplimit to 256, and when such route will be used, packets will be sent with hoplimit/ttl equal to 0. This commit adds checks for the RTAX_HOPLIMIT value, in both ipv4 ipv6 route code, substituting any value greater than 255 with 255. This is consistent with what is currently done for ADVMSS and MTU in the ipv4 code. Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The slab name ends up being visible in the directory structure under /sys, and even if you don't have access rights to the file you can see the filenames. Just use a 64-bit counter instead of the pointer to the 'net' structure to generate a unique name. This code will go away in 4.7 when the conntrack code moves to a single kmemcache, but this is the backportable simple solution to avoiding leaking kernel pointers to user space.

Pull cgroup fixes from Tejun Heo: "During v4.6-rc1 cgroup namespace support was merged. There is an issue where it's impossible to tell whether a given cgroup mount point is bind mounted or namespaced. Serge has been working on the issue but it took longer than expected to resolve, so the late pull request. Given that it's a completely new feature and the patches don't touch anything else, the risk seems acceptable. However, if this is too late, an alternative is plugging new cgroup ns creation for v4.6 and retrying for v4.7" * 'for-4.6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: fix compile warning kernfs: kernfs_sop_show_path: don't return 0 after seq_dentry call cgroup, kernfs: make mountinfo show properly scoped path for cgroup namespaces kernfs_path_from_node_locked: don't overwrite nlen
