2019-09-27ptp: correctly disable flags on old ioctlsJacob Keller1-2/+2
Commit 415606588c61 ("PTP: introduce new versions of IOCTLs", 2019-09-13) introduced new versions of the PTP ioctls which actually validate that the flags are acceptable values. As part of this, it cleared the flags value using a bitwise and+negation, in an attempt to prevent the old ioctl from accidentally enabling new features. This is incorrect for a couple of reasons. First, it results in accidentally preventing previously working flags on the request ioctl. By clearing the "valid" flags, we now no longer allow setting the enable, rising edge, or falling edge flags. Second, if we add new additional flags in the future, they must not be set by the old ioctl. (Since the flag wasn't checked before, we could potentially break userspace programs which sent garbage flag data. The correct way to resolve this is to check for and clear all but the originally valid flags. Create defines indicating which flags are correctly checked and interpreted by the original ioctls. Use these to clear any bits which will not be correctly interpreted by the original ioctls. In the future, new flags must be added to the VALID_FLAGS macros, but *not* to the V1_VALID_FLAGS macros. In this way, new features may be exposed over the v2 ioctls, but without breaking previous userspace which happened to not clear the flags value properly. The old ioctl will continue to behave the same way, while the new ioctl gains the benefit of using the flags fields.

2019-09-27net: dsa: microchip: Always set regmap stride to 1Marek Vasut1-1/+1
The regmap stride is set to 1 for regmap describing 8bit registers already. However, for 16/32/64bit registers, the stride is 2/4/8 respectively. This is not correct, as the switch protocol supports unaligned register reads and writes and the KSZ87xx even uses such unaligned register accesses to read e.g. MIB counter. This patch fixes MIB counter access on KSZ87xx. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Andrew Lunn <andrew@lunn.ch> Cc: David S.

Later when the skb is being freed and the skb's truesize is subtracted from its sk's sk_wmem_alloc in tcp_wfree(), underflow occurs. macsec is calling gro_cells_receive() to receive a packet, which actually requires skb->sk to be NULL. However when macsec dev is over veth, it's possible the skb->sk is still set if the skb was not unshared or expanded from the peer veth. ip_rcv() is calling skb_orphan() to drop the skb's sk for tproxy, but it is too late for macsec's calling gro_cells_receive(). So fix it by dropping the skb's sk earlier on rx path of macsec.

2019-09-25vfio/type1: untag user pointers in vaddr_get_pfnAndrey Konovalov1-0/+2
This patch is a part of a series that extends kernel ABI to allow to pass tagged user pointers (with the top byte set to something else other than 0x00) as syscall arguments. vaddr_get_pfn() uses provided user pointers for vma lookups, which can only by done with untagged pointers. Untag user pointers in this function.

This patch is a part of a series that extends kernel ABI to allow to pass tagged user pointers (with the top byte set to something else other than 0x00) as syscall arguments. In radeon_gem_userptr_ioctl() an MMU notifier is set up with a (tagged) userspace pointer. The untagged address should be used so that MMU notifiers for the untagged address get correctly matched up with the right BO. This funcation also calls radeon_ttm_tt_pin_userptr(), which uses provided user pointers for vma lookups, which can only by done with untagged pointers. This patch untags user pointers in radeon_gem_userptr_ioctl().

This patch is a part of a series that extends kernel ABI to allow to pass tagged user pointers (with the top byte set to something else other than 0x00) as syscall arguments. In amdgpu_gem_userptr_ioctl() and amdgpu_amdkfd_gpuvm.c/init_user_pages() an MMU notifier is set up with a (tagged) userspace pointer.

This patch untag user pointers in amdgpu_gem_userptr_ioctl() for the GEM case and in amdgpu_amdkfd_gpuvm_ alloc_memory_of_gpu() for the KFD case. This also makes sure that an untagged pointer is passed to amdgpu_ttm_tt_get_user_pages(), which uses it for vma lookups.

Add RB_DECLARE_CALLBACKS_MAX, which generates augmented rbtree callbacks for the case where the augmented value is a scalar whose definition follows a max(f(node)) pattern. This actually covers all present uses of RB_DECLARE_CALLBACKS, and saves some (source) code duplication in the various RBCOMPUTE function definitions.
