6fd2c68da5 net: mana: Add rmb after checking owner bits
Per GDMA spec, rmb is necessary after checking owner_bits, before
reading EQ or CQ entries.

Add rmb in these two places to comply with the specs.

198eb7e1b8 i40e: Fix set max_tx_rate when it is lower than 1 Mbps
While converting max_tx_rate from bytes to Mbps, this value was set to 0,
if the original value was lower than 125000 bytes (1 Mbps). This would
cause no transmission rate limiting to occur. This happened due to lack of
check of max_tx_rate against the 1 Mbps value for max_tx_rate and the
following division by 125000. Fix this issue by adding a helper
i40e_bw_bytes_to_mbits() which sets max_tx_rate to minimum usable value of
50 Mbps, if its value is less than 1 Mbps, otherwise do the required
conversion by dividing by 125000.

399c98c4dc iavf: Fix set max MTU size with port VLAN and jumbo frames
After setting port VLAN and MTU to 9000 on VF with ice driver there
was an iavf error
"PF returned error -5 (IAVF_ERR_PARAM) to our request 6".

During queue configuration, VF's max packet size was set to
IAVF_MAX_RXBUFFER but on ice max frame size was smaller by VLAN_HLEN
due to making some space for port VLAN as VF is not aware whether it's
in a port VLAN. This mismatch in sizes caused ice to reject queue
configuration with ERR_PARAM error. Proper max_mtu is sent from ice PF
to VF with GET_VF_RESOURCES msg but VF does not look at this.

In iavf change max_frame from IAVF_MAX_RXBUFFER to max_mtu
received from pf with GET_VF_RESOURCES msg to make vf's
max_frame_size dependent from pf. Add check if received max_mtu is
not in eligible range then set it to IAVF_MAX_RXBUFFER.

782b1f70f8 um: fix default console kernel parameter
OpenWrt's UML with 5.15 was producing odd errors/warnings during preinit
part of the early userspace portion:

|[    0.000000] Kernel command line: ubd0=root.img root=98:0 console=tty
|[...]
|[    0.440000] random: jshn: uninitialized urandom read (4 bytes read)

|/etc/preinit: line 48: can't create /dev/tty: No such device or address
|/etc/preinit: line 58: can't open /dev/tty: No such device or address
|[...] repeated many times

That "/dev/tty" came from the command line (which is automatically
added if no console= parameter was specified for the uml binary).

The TLDP project tells the following about the /dev/tty:
<https://tldp.org/HOWTO/Text-Terminal-HOWTO-7.html#ss7.3>
| /dev/tty stands for the controlling terminal (if any) for the current
| process.[...]
| /dev/tty is something like a link to the actually terminal device[..]

The "(if any)" is important here, since it's possible for processes to
not have a controlling terminal.

I think this was a simple typo and the author wanted tty0 there.

522c9a64c7 KVM: arm64: Use kmemleak_free_part_phys() to unregister hyp_mem_base
With commit 0c24e06119 ("mm: kmemleak: add rbtree and store physical
address for objects allocated with PA"), kmemleak started to put the
objects allocated with physical address onto object_phys_tree_root tree.
The kmemleak_free_part() therefore no longer worked as expected on
physically allocated objects (hyp_mem_base in this case) as it attempted to
search and remove things in object_tree_root tree.

Fix it by using kmemleak_free_part_phys() to unregister hyp_mem_base. This
fixes an immediate crash when booting a KVM host in protected mode with
kmemleak enabled.

db7ba07108 s390/dasd: fix Oops in dasd_alias_get_start_dev due to missing pavgroup
Fix Oops in dasd_alias_get_start_dev() function caused by the pavgroup
pointer being NULL.

The pavgroup pointer is checked on the entrance of the function but
without the lcu->lock being held. Therefore there is a race window
between dasd_alias_get_start_dev() and _lcu_update() which sets
pavgroup to NULL with the lcu->lock held.

Fix by checking the pavgroup pointer with lcu->lock held.

e9f3f8f488 MIPS: Loongson32: Fix PHY-mode being left unspecified
commit 0060c87833 ("net: stmmac: implement support for passive mode
converters via dt") has changed the plat->interface field semantics from
containing the PHY-mode to specifying the MAC-PCS interface mode. Due to
that the loongson32 platform code will leave the phylink interface
uninitialized with the PHY-mode intended by the means of the actual
platform setup. The commit-author most likely has just missed the
arch-specific code to fix. Let's mend the Loongson32 platform code then by
assigning the PHY-mode to the phy_interface field of the STMMAC platform
data.

In some certain timing, the scheduled work could be run before

Fix it by caching the RCU flag inside protected area, just like 'refcnt'

c3afa2a402 ALSA: core: Fix double-free at snd_card_new()
During the code change to add the support for devres-managed card
instance, we put an explicit kfree(card) call at the error path in
snd_card_new().  This is needed for the early error path before the
card is initialized with the device, but is rather superfluous and
causes a double-free at the error path after the card instance is
initialized, as the destructor of the card object already contains a
kfree() call.

This patch fixes the double-free situation by removing the superfluous
kfree().  Meanwhile we need to call kfree() explicitly for the early
error path, so it's added there instead.

Pull parisc architecture fixes from Helge Deller:
 "Some small parisc architecture fixes for 6.0-rc6:

  One patch lightens up a previous commit and thus unbreaks building the
  debian kernel, which tries to configure a 64-bit kernel with the
  ARCH=parisc environment variable set.

  The other patches fixes asm/errno.h includes in the tools directory
  and cleans up memory allocation in the iosapic driver.

  Summary:

   - Allow configuring 64-bit kernel with ARCH=parisc

   - Fix asm/errno.h includes in tools directory for parisc and xtensa

   - Clean up iosapic memory allocation

   - Minor typo and spelling fixes"

2a5be6d134 i2c: mlxbf: incorrect base address passed during io write
Correct the base address used during io write.
This bug had no impact over the overall functionality of the read and write
transactions. MLXBF_I2C_CAUSE_OR_CLEAR=0x18 so writing to (smbus->io + 0x18)
instead of (mst_cause->ioi + 0x18) actually writes to the sc_low_timeout

762df359aa riscv: fix a nasty sigreturn bug...
riscv has an equivalent of arm bug fixed by 653d48b221 ("arm: fix
really nasty sigreturn bug"); if signal gets caught by an interrupt that
hits when we have the right value in a0 (-513), *and* another signal
gets delivered upon sigreturn() (e.g. included into the blocked mask for
the first signal and posted while the handler had been running), the
syscall restart logics will see regs->cause equal to EXC_SYSCALL (we are
in a syscall, after all) and a0 already restored to its original value
(-513, which happens to be -ERESTARTNOINTR) and assume that we need to
apply the usual syscall restart logics.

Subject: [PATCH net v3 0/4] Unsync addresses from ports when stopping aggregated devices
Date: Wed,  7 Sep 2022 16:56:38 +0900	[thread overview]
Message-ID: <20220907075642.475236-1-bpoirier@nvidia.com> (raw)

This series fixes similar problems in the bonding and team drivers.

Because of missing dev_{uc,mc}_unsync() calls, addresses added to
underlying devices may be leftover after the aggregated device is deleted.
Add the missing calls and a few related tests.

v2:
* fix selftest installation, see patch 3

v3:
* Split lacpdu_multicast changes to their own patch, #1
* In ndo_{add,del}_slave methods, only perform address list changes when
  the aggregated device is up (patches 2 & 3)
* Add selftest function related to the above change (patch 4)

Test addition and removal of the LACPDU multicast address on underlying
devices by the bonding driver.

v2:
* add lag_lib.sh to TEST_FILES

v3:
* extend bond_listen_lacpdu_multicast test to init_state up and down cases
* remove some superfluous shell syntax and 'set dev ... up' commands
