2017-02-19Fix missing sanity check in /dev/sgAl Viro
What happens is that a write to /dev/sg is given a request with non-zero ->iovec_count combined with zero ->dxfer_len. Or with ->dxferp pointing to an array full of empty iovecs. Having write permission to /dev/sg shouldn't be equivalent to the ability to trigger BUG_ON() while holding spinlocks... Found by Dmitry Vyukov and syzkaller.

2017-02-19scsi: don't BUG_ON() empty DMA transfersJohannes Thumshirn
Don't crash the machine just because of an empty transfer. Use WARN_ON() combined with returning an error. Found by Dmitry Vyukov and syzkaller. [ Changed to "WARN_ON_ONCE()". Al has a patch that should fix the root cause, but a BUG_ON() is not acceptable in any case, and a WARN_ON() might still be a cause of excessive log spamming. NOTE! If this warning ever triggers, we may end up leaking resources, since this doesn't bother to try to clean the command up. So this WARN_ON_ONCE() triggering does imply real problems. But BUG_ON() is much worse. People really need to stop using BUG_ON() for "this shouldn't ever happen". It makes pretty much any bug worse. - Linus ] Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de> Reported-by: Dmitry Vyukov <dvyukov@google.com> Cc: James Bottomley <jejb@linux.vnet.ibm.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

spi: Fixes for v4.10 The usual small smattering of driver specific fixes. A few bits that stand out here: - The R-Car patches adding fallbacks are just adding new compatible strings to the driver so that device trees are written in a more robustly future proof fashion, this isn't strictly a fix but it's just new IDs and it's better to get it into mainline sooner to improve the ABI. - The DesignWare "switch to new API part 2" patch is actually a misleadingly titled fix for a bit that got missed in the original conversion. # gpg: Signature made Thu 19 Jan 2017 14:54:15 GMT # gpg: using RSA key ADE668AA675718B59FE29FEA24D68B725D5487D0 # gpg: issuer "broonie@kernel.org" # gpg: key 0D9EACE2CD7BEEBC: no public key for trusted key - skipped # gpg: key 0D9EACE2CD7BEEBC marked as ultimately trusted # gpg: key CCB0A420AF88CD16: no public key for trusted key - skipped # gpg: key CCB0A420AF88CD16 marked as ultimately trusted # gpg: key 162614E316005C11: no public key for trusted key - skipped # gpg: key 162614E316005C11 marked as ultimately trusted # gpg: key A730C53A5621E907: no public key for trusted key - skipped # gpg: key A730C53A5621E907 marked as ultimately trusted # gpg: key 276568D75C6153AD: no public key for trusted key - skipped # gpg: key 276568D75C6153AD marked as ultimately trusted # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" [ultimate] # gpg: aka "Mark Brown <broonie@debian.org>" [ultimate] # gpg: aka "Mark Brown <broonie@kernel.org>" [ultimate] # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" [ultimate] # gpg: aka "Mark Brown <broonie@linaro.org>" [ultimate] # gpg: aka "Mark Brown <Mark.Brown@linaro.org>" [ultimate]

2017-02-18i40e: mark the value passed to csum_replace_by_diff as __wsumJacob Keller
Fix, or rather, avoid a sparse warning caused by the fact that csum_replace_by_diff expects to receive a __wsum value. Since the calculation appears to work, simply typecast the passed paylen value to __wsum to avoid the warning. This seems pretty fishy since __wsum was obviously annotated as a separate type on purpose, so this throws the entire calculation into question. Since it currently appears to behave as expected, the typecast is probably safe.

2017-02-18i40e: Error handling for link eventHarshitha Ramamurthy
There exists an intermittent bug which causes the 'Link Detected' field reported by the 'ethtool <iface>' command to be 'Yes' when in fact, there is no link. This patch fixes the problem by enabling temporary link polling when i40e_get_link_status returns an error. This causes the driver to remember that an admin queue command failed and polls, until the function returns with a success.

2017-02-18i40e: Fix Adaptive ITR enablingCarolyn Wyborny
This patch fixes a bug introduced with the addition of the per queue ITR feature support in ethtool. With that addition, there were functions added which converted the ITR settings to binary values. The IS_ENABLED macros that run on those values check whether a bit is set or not and with the value being binary, the bit check always returned ITR disabled which prevents any updating of the ITR rate. This patch fixes the problem by changing the functions to return the current ITR value instead and renaming it to better reflect its function. These functions now provide a value which will be accurately asessed and update the ITR as intended.

2017-02-18i40evf: free rings in remove functionMitch Williams
When the i40evf_remove() calls netdev close, the device doesn't actually close - it schedules the work for the watchdog to perform. Since we're stopping the watchdog, this work doesn't get done. However, we're resetting the part, so we can free resources after the reset request has gone through. This plugs a memory leak.

2017-02-18i40e: enable mc magic pkt wakeup during power downJoshua Hay
This patch adds a call to the mac_address_write admin q function during power down to update the PRTPM_SAH/SAL registers with the MC_MAG_EN bit thus enabling multicast magic packet wakeup. A FW workaround is needed to write the multicast magic wake up enable bit in the PRTPM_SAH register. The FW expects the mac address write admin q cmd to be called first with one of the WRITE_TYPE_LAA flags and then with the multicast relevant flags. *Note: This solution only works for X722 devices currently. A PFR will clear the previously mentioned bit by default, but X722 has support for a WOL_PRESERVE_ON_PFR flag which prevents the bit from being cleared. Once other devices support this flag, this solution should work as well.

2017-02-18i40e: fix disable overflow promiscuous modeAlan Brady
There exists a bug in which the driver is unable to exit overflow promiscuous mode after having added "too many" mac filters. It is expected that after triggering overflow promiscuous, removing the failed/extra filters should then disable overflow promiscuous mode. The bug exists because we were intentionally skipping the sync_vsi_filter path in cases where we were removing failed filters since they shouldn't have been added to the firmware in the first place, however we still need to go through the sync_vsi_filter code path to determine whether or not it is ok to exit overflow promiscuous mode. This patch fixes the bug by making sure we go through the sync_vsi_filter path in cases of failed filters.
