net: phy: extract pause mode

2019-10-05T01:11:08+00:00

Extract the update of phylib's software pause mode state from genphy_read_status(), so that we can re-use this functionality with PHYs that have alternative ways to read the negotiation results. Tested-by: tinywrkb Reviewed-by: Andrew Lunn Signed-off-by: Russell King Signed-off-by: David S. Miller

net: phy: extract link partner advertisement reading

2019-10-05T01:11:08+00:00

Move reading the link partner advertisement out of genphy_read_status() into its own separate function. This will allow re-use of this code by PHY drivers that are able to read the resolved status from the PHY.

net: phy: fix write to mii-ctrl1000 register

2019-10-05T01:11:08+00:00

When userspace writes to the MII_ADVERTISE register, we update phylib's advertising mask and trigger a renegotiation. However, writing to the MII_CTRL1000 register, which contains the gigabit advertisement, does neither. This can lead to phylib's copy of the advertisement becoming de-synced with the values in the PHY register set, which can result in incorrect negotiation resolution.

Pull copy_struct_from_user() helper from Christian Brauner: "This contains the copy_struct_from_user() helper which got split out from the openat2() patchset. It is a generic interface designed to copy a struct from userspace. The helper will be especially useful for structs versioned by size of which we have quite a few. This allows for backwards compatibility, i.e. an extended struct can be passed to an older kernel, or a legacy struct can be passed to a newer kernel. For the first case (extended struct, older kernel) the new fields in an extended struct can be set to zero and the struct safely passed to an older kernel. The most obvious benefit is that this helper lets us get rid of duplicate code present in at least sched_setattr(), perf_event_open(), and clone3(). More importantly it will also help to ensure that users implementing versioning-by-size end up with the same core semantics. This point is especially crucial since we have at least one case where versioning-by-size is used but with slighly different semantics: sched_setattr(), perf_event_open(), and clone3() all do do similar checks to copy_struct_from_user() while rt_sigprocmask(2) always rejects differently-sized struct arguments. With this pull request we also switch over sched_setattr(), perf_event_open(), and clone3() to use the new helper" * tag 'copy-struct-from-user-v5.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: usercopy: Add parentheses around assignment in test_copy_struct_from_user perf_event_open: switch to copy_struct_from_user() sched_setattr: switch to copy_struct_from_user() clone3: switch to copy_struct_from_user() lib: introduce copy_struct_from_user() helper
