2019-10-18RDMA/iwcm: move iw_rem_ref() calls out of spinlockKrishnamraju Eraparaju
kref release routines usually perform memory release operations, hence, they should not be called with spinlocks held. one such case is: SIW kref release routine siw_free_qp(), which can sleep via vfree() while freeing queue memory. Hence, all iw_rem_ref() calls in IWCM are moved out of spinlocks. Fixes: 922a8e9fb2e0 ("RDMA: iWARP Connection Manager.")

2019-10-18iw_cxgb4: fix ECN check on the passive acceptPotnuri Bharat Teja
pass_accept_req() is using the same skb for handling accept request and sending accept reply to HW. Here req and rpl structures are pointing to same skb->data which is over written by INIT_TP_WR() and leads to accessing corrupt req fields in accept_cr() while checking for ECN flags.

2019-10-18Merge branch 'net-bcmgenet-restore-internal-EPHY-support'David S. Miller
Doug Berger says: ==================== net: bcmgenet: restore internal EPHY support I managed to get my hands on an old BCM97435SVMB board to do some testing with the latest kernel and uncovered a number of things that managed to get broken over the years (some by me ;). This commit set attempts to correct the errors I observed in my testing. The first commit applies to all internal PHYs to restore proper reporting of link status when a link comes up. The second commit restores the soft reset to the initialization of the older internal EPHYs used by 40nm Set-Top Box devices. The third corrects a bug I introduced when removing excessive soft resets by altering the initialization sequence in a way that keeps the GENETv3 MAC interface happy. Finally, I observed a number of issues when manually configuring the network interface of the older EPHYs that appear to be resolved by the fourth commit. ==================== Signed-off-by: David S.

2019-10-18net: bcmgenet: reset 40nm EPHY on energy detectDoug Berger
The EPHY integrated into the 40nm Set-Top Box devices can falsely detect energy when connected to a disabled peer interface. When the peer interface is enabled the EPHY will detect and report the link as active, but on occasion may get into a state where it is not able to exchange data with the connected GENET MAC. This issue has not been observed when the link parameters are auto-negotiated; however, it has been observed with a manually configured link. It has been empirically determined that issuing a soft reset to the EPHY when energy is detected prevents it from getting into this bad state.

2019-10-18net: bcmgenet: soft reset 40nm EPHYs before MAC initDoug Berger
It turns out that the "Workaround for putting the PHY in IDDQ mode" used by the internal EPHYs on 40nm Set-Top Box chips when powering down puts the interface to the GENET MAC in a state that can cause subsequent MAC resets to be incomplete. Rather than restore the forced soft reset when powering up internal PHYs, this commit moves the invocation of phy_init_hw earlier in the MAC initialization sequence to just before the MAC reset in the open and resume functions. This allows the interface to be stable and allows the MAC resets to be successful. The bcmgenet_mii_probe() function is split in two to accommodate this. The new function bcmgenet_mii_connect() handles the first half of the functionality before the MAC initialization, and the bcmgenet_mii_config() function is extended to provide the remaining PHY configuration following the MAC initialization.

2019-10-18drm/i915: Nuke 'realloc_pipes'Ville Syrjälä
The 'realloc_pipes' bitmask is pointless. It is either: a) the set of pipes which are already part of the state, in which case adding them again is entirely redundant b) the set of all pipes which we then add to the state Also the fact that 'realloc_pipes' uses the crtc indexes is going to bite is at some point so best get rid of it quick.

2019-10-18drm/i915: Refuse modes with hdisplay==4096 on pre-HSW DPVille Syrjälä
The DP port/pipe goes wonky if we try to use timings with hdisplay==4096 on pre-HSW platforms. The link fails to train and the pipe may not signal vblank interrupts. On HDMI such at mode works just fine (tested on ELK/SNB/CHV). So let's refuse such modes on DP on older platforms.

2019-10-18symbol namespaces: revert to previous __ksymtab name schemeMatthias Maennich
The introduction of Symbol Namespaces changed the naming schema of the __ksymtab entries from __kysmtab__symbol to __ksymtab_NAMESPACE.symbol. That caused some breakages in tools that depend on the name layout in either the binaries(vmlinux,*.ko) or in System.map. E.g. kmod's depmod would not be able to read System.map without a patch to support symbol namespaces. A warning reported by depmod for namespaced symbols would look like depmod: WARNING: [...]/uas.ko needs unknown symbol usb_stor_adjust_quirks In order to address this issue, revert to the original naming scheme and rather read the __kstrtabns_<symbol> entries and their corresponding values from __ksymtab_strings to update the namespace values for symbols. After having read all symbols and handled them in handle_modversions(), the symbols are created. In a second pass, read the __kstrtabns_ entries and update the namespaces accordingly. Fixes: 8651ec01daed ("module: add support for symbol namespaces.")

2019-10-18modpost: make updating the symbol namespace explicitMatthias Maennich
Setting the symbol namespace of a symbol within sym_add_exported feels displaced and lead to issues in the current implementation of symbol namespaces. This patch makes updating the namespace an explicit call to decouple it from adding a symbol to the export list.

2019-10-18modpost: delegate updating namespaces to separate functionMatthias Maennich
Let the function 'sym_update_namespace' take care of updating the namespace for a symbol. While this currently only replaces one single location where namespaces are updated, in a following patch, this function will get more call sites. The function signature is intentionally close to sym_update_crc and taking the name by char* seems like unnecessary work as the symbol has to be looked up again. In a later patch of this series, this concern will be addressed. This function ensures that symbol::namespace is either NULL or has a valid non-empty value. Previously, the empty string was considered 'no namespace' as well and this lead to confusion.
