2021-10-29bcache: replace snprintf in show functions with sysfs_emitQing Wang
coccicheck complains about the use of snprintf() in sysfs show functions. Fix the following coccicheck warning: drivers/md/bcache/sysfs.h:54:12-20: WARNING: use scnprintf or sprintf. Implement sysfs_print() by sysfs_emit() and remove snprint() since no one uses it any more.

2021-10-29bcache: move uapi header bcache.h to bcache code directoryColy Li
The header file include/uapi/linux/bcache.h is not really a user space API heaer. This file defines the ondisk format of bcache internal meta data but no one includes it from user space, bcache-tools has its own copy of this header with minor modification. Therefore, this patch moves include/uapi/linux/bcache.h to bcache code directory as drivers/md/bcache/bcache_ondisk.h.

2021-10-29net: phylink: avoid mvneta warning when setting pause parametersRussell King (Oracle)
mvneta does not support asymetric pause modes, and it flags this by the lack of AsymPause in the supported field. When setting pause modes, we check that pause->rx_pause == pause->tx_pause, but only when pause autoneg is enabled. When pause autoneg is disabled, we still allow pause->rx_pause != pause->tx_pause, which is incorrect when the MAC does not support asymetric pause, and causes mvneta to issue a warning. Fix this by removing the test for pause->autoneg, so we always check that pause->rx_pause == pause->tx_pause for network devices that do not support AsymPause.

2021-10-29Merge branch 'MCTP-flow-support'David S. Miller
Jeremy Kerr says: ==================== MCTP flow support For certain MCTP transport bindings, the binding driver will need to be aware of request/response pairing. For example, the i2c binding may need to set multiplexer configuration when expecting a response from a device behind a mux. This series implements a mechanism for informing the driver about these flows, so it can implement transport-specific behaviour when a flow is in progress (ie, a response is expected, and/or we time-out on that expectation). We use a skb extension to notify the driver about the presence of a flow, and a new dev->ops callback to notify about a flow's destruction. ==================== Signed-off-by: David S.

2021-10-29Revert "btrfs: compression: drop kmap/kunmap from lzo"David Sterba
This reverts commit 8c945d32e60427cbc0859cf7045bbe6196bb03d8. The kmaps in compression code are still needed and cause crashes on 32bit machines (ARM, x86). Reproducible eg. by running fstest btrfs/004 with enabled LZO or ZSTD compression. The revert does not apply cleanly due to changes in a6e66e6f8c1b ("btrfs: rework lzo_decompress_bio() to make it subpage compatible") that reworked the page iteration so the revert is done to be equivalent to the original code.

2021-10-29sctp: allow IP fragmentation when PLPMTUD enters Error stateXin Long
Currently when PLPMTUD enters Error state, transport pathmtu will be set to MIN_PLPMTU(512) while probe is continuing with BASE_PLPMTU(1200). It will cause pathmtu to stay in a very small value, even if the real pmtu is some value like 1000. RFC8899 doesn't clearly say how to set the value in Error state. But one possibility could be keep using BASE_PLPMTU for the real pmtu, but allow to do IP fragmentation when it's in Error state. As it says in rfc8899#section-5.4: Some paths could be unable to sustain packets of the BASE_PLPMTU size. The Error State could be implemented to provide robustness to such paths. This allows fallback to a smaller than desired PLPMTU rather than suffer connectivity failure. This could utilize methods such as endpoint IP fragmentation to enable the PL sender to communicate using packets smaller than the BASE_PLPMTU. This patch is to set pmtu to BASE_PLPMTU instead of MIN_PLPMTU for Error state in sctp_transport_pl_send/toobig(), and set packet ipfragok for non-probe packets when it's in Error state.

Provide devlink dev info "fw" version on older firmware. v2: In patch 3, don't use devlink_reload_disable() and devlink_reload_enable() which are no longer available in the latest kernel. Instead, check that the netdev is not in unregistered state before proceeding with reload. In patch 14, use min_t() instead of min() to fix the mismatched type warning. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2021-10-29bnxt_en: Provide stored devlink "fw" version on older firmwareVikas Gupta
On older firmware that doesn't support the HWRM_NVM_GET_DEV_INFO command that returns detailed stored firmware versions, fallback to use the same firmware package version that is reported to ethtool. Refactor bnxt_get_pkgver() in bnxt_ethtool.c so that devlink can call and get the package version.

2021-10-29bnxt_en: implement firmware live patchingEdwin Peer
Live patches are activated by using the 'limit no_reset' option when performing a devlink dev reload fw_activate operation. These packages must first be installed on the device in the usual way. For example, via devlink dev flash or ethtool -f. The devlink device info has also been enhanced to render stored and running live patch versions.

2021-10-29bnxt_en: Update firmware interface to 1.10.2.63Michael Chan
The main changes are firmware live patch support and 2 additional FEC standard counters. Add the matching FEC counters to ethtool counter array. Firmware older than 220 does not return the proper size of the extended RX counters so we need to cap it at the smaller legacy size. Otherwise the new FEC counters may show up with garbage values.

2021-10-29bnxt_en: implement dump callback for fw health reporterEdwin Peer
Populate the dump with firmware 'live' coredump data. This includes the information stored in NVRAM by the firmware exception handler prior to recovery. Thus, the live dump includes the desired crash context. Firmware does not support HWRM calls after RESET_NOTIFY, so there is no supported way to capture a coredump during the auto dump phase. Detect this and abort when called from devlink_health_report(). Signed-off-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.
