      veth: Add updating of trans_start · e66e257a
      Jay Vosburgh authored 
      Since commit 21a75f09 ("bonding: Fix ARP monitor validation"),
the bonding ARP / ND link monitors depend on the trans_start time to
determine link availability.  NETIF_F_LLTX drivers must update trans_start
directly, which veth does not do.  This prevents use of the ARP or ND link
monitors with veth interfaces in a bond.

	Resolve this by having veth_xmit update the trans_start time.

      net: fix data-race in dev_isalive() · cc26c266
      Eric Dumazet authored 
      dev_isalive() is called under RTNL or dev_base_lock protection.

This means that changes to dev->reg_state should be done with both locks held.

      Even when the eth port is resticted to work with speeds not higher than 1G,
and so the eth driver is requesting the phy (via phylink) to advertise up

and 5G speeds.
Clear these advertising defaults when requested.

      netfs: fix up netfs_inode_init() docbook comment · 018ab4fa
      Linus Torvalds authored 
      Commit e81fb419 ("netfs: Further cleanups after struct netfs_inode
wrapper introduced") changed the argument types and names, and actually
updated the comment too (although that was thanks to David Howells, not
me: my original patch only changed the code).

But the comment fixup didn't go quite far enough, and didn't change the
argument name in the comment, resulting in

      ice: Fix memory corruption in VF driver · efe41860
      Przemyslaw Patynowski authored 
      Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled,
when it requests a reset. If PF driver assumes that VF is disabled,
while VF still has queues configured, VF may unmap DMA resources.
In such scenario device still can map packets to memory, which ends up
silently corrupting it.
Previously, VF driver could experience memory corruption, which lead to
crash:

      ice: Fix queue config fail handling · be2af714
      Przemyslaw Patynowski authored 
      Disable VF's RX/TX queues, when VIRTCHNL_OP_CONFIG_VSI_QUEUES fail.
Not disabling them might lead to scenario, where PF driver leaves VF
queues enabled, when VF's VSI failed queue config.
In this scenario VF should not have RX/TX queues enabled. If PF failed
to set up VF's queues, VF will reset due to TX timeouts in VF driver.
Initialize iterator 'i' to -1, so if error happens prior to configuring
queues then error path code will not disable queue 0. Loop that
configures queues will is using same iterator, so error path code will
only disable queues that were configured.

      ice: Fix PTP TX timestamp offset calculation · 71a579f0
      Michal Michalik authored 
      The offset was being incorrectly calculated for E822 - that led to
collisions in choosing TX timestamp register location when more than
one port was trying to use timestamping mechanism.

In E822 one quad is being logically split between ports, so quad 0 is
having trackers for ports 0-3, quad 1 ports 4-7 etc. Each port should
have separate memory location for tracking timestamps. Due to error for
example ports 1 and 2 had been assigned to quad 0 with same offset (0),
while port 1 should have offset 0 and 1 offset 16.

Fix it by correctly calculating quad offset.

 "While last week's pull request contained miscellaneous fixes for x86,
  this one covers other architectures, selftests changes, and a bigger
  series for APIC virtualization bugs that were discovered during 5.20
  development. The idea is to base 5.20 development for KVM on top of
  this tag.

  ARM64:

   - Properly reset the SVE/SME flags on vcpu load

   - Fix a vgic-v2 regression regarding accessing the pending state of a
     HW interrupt from userspace (and make the code common with vgic-v3)

   - Fix access to the idreg range for protected guests

   - Ignore 'kvm-arm.mode=protected' when using VHE

   - Return an error from kvm_arch_init_vm() on allocation failure

   - A bunch of small cleanups (comments, annotations, indentation)

  RISC-V:

   - Typo fix in arch/riscv/kvm/vmid.c

   - Remove broken reference pattern from MAINTAINERS entry

  x86-64:

   - Fix error in page tables with MKTME enabled

   - Dirty page tracking performance test extended to running a nested
     guest

   - Disable APICv/AVIC in cases that it cannot implement correctly"

      mlxsw: spectrum_cnt: Reorder counter pools · 4b7a632a
      Petr Machata authored 
      Both RIF and ACL flow counters use a 24-bit SW-managed counter address to
communicate which counter they want to bind.

In a number of Spectrum FW releases, binding a RIF counter is broken and
slices the counter index to 16 bits. As a result, on Spectrum-2 and above,
no more than about 410 RIF counters can be effectively used. This
translates to 205 netdevices for which L3 HW stats can be enabled. (This
does not happen on Spectrum-1, because there are fewer counters available
overall and the counter index never exceeds 16 bits.)

Binding counters to ACLs does not have this issue. Therefore reorder the
counter allocation scheme so that RIF counters come first and therefore get
lower indices that are below the 16-bit barrier.

      fs: account for group membership · 168f9128
      Christian Brauner authored 
      When calling setattr_prepare() to determine the validity of the
attributes the ia_{g,u}id fields contain the value that will be written
to inode->i_{g,u}id. This is exactly the same for idmapped and
non-idmapped mounts and allows callers to pass in the values they want
to see written to inode->i_{g,u}id.

When group ownership is changed a caller whose fsuid owns the inode can
change the group of the inode to any group they are a member of. When
searching through the caller's groups we need to use the gid mapped
according to the idmapped mount otherwise we will fail to change
ownership for unprivileged users.

Consider a caller running with fsuid and fsgid 1000 using an idmapped
mount that maps id 65534 to 1000 and 65535 to 1001. Consequently, a file
owned by 65534:65535 in the filesystem will be owned by 1000:1001 in the
idmapped mount.

The caller now requests the gid of the file to be changed to 1000 going
through the idmapped mount. In the vfs we will immediately map the
requested gid to the value that will need to be written to inode->i_gid
and place it in attr->ia_gid. Since this idmapped mount maps 65534 to
1000 we place 65534 in attr->ia_gid.

When we check whether the caller is allowed to change group ownership we
first validate that their fsuid matches the inode's uid. The
inode->i_uid is 65534 which is mapped to uid 1000 in the idmapped mount.
Since the caller's fsuid is 1000 we pass the check.

We now check whether the caller is allowed to change inode->i_gid to the
requested gid by calling in_group_p(). This will compare the passed in
gid to the caller's fsgid and search the caller's additional groups.

Since we're dealing with an idmapped mount we need to pass in the gid
mapped according to the idmapped mount. This is akin to checking whether
a caller is privileged over the future group the inode is owned by. And
that needs to take the idmapped mount into account. Note, all helpers
are nops without idmapped mounts.

New regression test sent to xfstests.

      amd-xgbe: Use platform_irq_count() · 884c65e4
      Jean-Philippe Brucker authored 
      The AMD XGbE driver currently counts the number of interrupts assigned
to the device by inspecting the pdev->resource array. Since commit
a1a2b712 ("of/platform: Drop static setup of IRQ resource from DT
core") removed IRQs from this array, the driver now attempts to get all
interrupts from 1 to -1U and gives up probing once it reaches an invalid
interrupt index.

Obtain the number of IRQs with platform_irq_count() instead.
