Currently, there is an out-of-bounds read on array ctrl->phys, once variable i reaches the maximum array size of SERDES_MAX in the for loop.

2018-10-22isdn: hfc_{pci,sx}: Avoid empty body if statementsNathan Chancellor
Clang warns: drivers/isdn/hisax/hfc_pci.c:131:34: error: if statement has empty body [-Werror,-Wempty-body] if (Read_hfc(cs, HFCPCI_INT_S1)); ^ drivers/isdn/hisax/hfc_pci.c:131:34: note: put the semicolon on a separate line to silence this warning In my attempt to hide the warnings because I thought they didn't serve any purpose[1], Masahiro Yamada pointed out that {Read,Write}_hfc in hci_pci.c should be using a standard register access method; otherwise, the compiler will just remove the if statements. For hfc_pci, use the versions of {Read,Write}_hfc found in drivers/isdn/hardware/mISDN/hfc_pCI.h while converting pci_io to be 'void __iomem *' (and clean up ioremap) then remove the empty if statements. For hfc_sx, {Read,Write}_hfc are already use a proper register accessor (inb, outb) so just remove the unnecessary if statements.

2018-10-19netpoll: allow cleanup to be synchronousDebabrata Banerjee
This fixes a problem introduced by: commit 2cde6acd49da ("netpoll: Fix __netpoll_rcu_free so that it can hold the rtnl lock") When using netconsole on a bond, __netpoll_cleanup can asynchronously recurse multiple times, each __netpoll_free_async call can result in more __netpoll_free_async's. This means there is now a race between cleanup_work queues on multiple netpoll_info's on multiple devices and the configuration of a new netpoll. For example if a netconsole is set to enable 0, reconfigured, and enable 1 immediately, this netconsole will likely not work. Given the reason for __netpoll_free_async is it can be called when rtnl is not locked, if it is locked, we should be able to execute synchronously. It appears to be locked everywhere it's called from. Generalize the design pattern from the teaming driver for current callers of __netpoll_free_async.

Clang warns: drivers/atm/zatm.c:513:7: error: while loop has empty body [-Werror,-Wempty-body] zwait; ^ drivers/atm/zatm.c:513:7: note: put the semicolon on a separate line to silence this warning Get rid of this warning by using an empty do-while loop. While we're at it, add parentheses to make it clear that this is a function-like macro.

2018-10-18net/mlx5e: Ethtool driver callback for query/set FEC policyShay Agroskin
Driver callback function for 'ethtool --show-fec', 'ethtool --set-fec' commands. The query function returns active and configured FEC policy for current link speed. The set function sets FEC policy for all supported link speeds. 1) If current link speed doesn't support requested FEC policy, the function fails. 2) If a different link speed doesn't support requested FEC policy, FEC capbilities for this speed are turned off.

2018-10-18net/mlx5e: Add port FEC get/set functionsShay Agroskin
Added functions to query and set link FEC policy. To get/set FEC capabilities in PPLM reg we need to query current link speed. 'mlx5_get_fec_speed_field' queries current link speed and returns correct field offset. FEC Query's return value is divided into 'active FEC policy', which is the FEC policy used by the link, and 'configured FEC policy', which is the FEC policy requested by the user. The two values may differ if: 1) FEC policy was configured to 'auto', in which case the active FEC policy would be the default FEC policy for current link speed. 2) FEC policy was changed, but no link reset is performed. In which case, the active FEC policy would become the configured one after a link reset. FEC set function sets FEC policy for all link speeds and perform link reset. 1) If current link speed doesn't support requested FEC policy, the function fails. 2) If a different link speed doesn't support requested FEC policy, FEC capbilities for this speed are turned off and a warning message is printed.

2018-10-18net/mlx5: Remove counter from idr after removing it from listVlad Buslov
Fs_counters list can temporary become unsorted when new counters are created/deleted concurrently. Idr is used to quickly lookup position to insert new counter in logarithmic time. However, if new flows are concurrently inserted during time window when flows with adjacent ids are already removed from idr but are still present in counters list, mlx5_fc_stats_work() observes counters list in inconsistent state, which results following warning: [ 1839.561955] mlx5_core 0000:81:00.0: mlx5_cmd_fc_bulk_get:587:(pid 729): Flow counter id (0x102d5) out of range (0x1c0a8..0x1c10b). Counter ignored. Move idr_remove() call to be executed synchronously with counter deletion from list. Extract this code to mlx5_fc_stats_remove() helper function that is called by workqueue job handler mlx5_fc_stats_work().

2018-10-18net/mlx5: Take fs_counters dellist before addlistVlad Buslov
In fs_counters elements from both addlist and dellist are removed by mlx5_fc_stats_work() without any locking. This introduces race condition when batch of new rules is created and then immediately deleted (for example, when error occurred during flow creation). In such case some of the rules might be in dellist, but not in addlist when mlx5_fc_stats_work() is executed concurrently with tc, which will result rule deletion and use-after-free on next iteration because deleted rules are still in addlist. Always take dellist first to guarantee that rules can only be deleted after they were removed from addlist.

2018-10-18net/mlx5: Refactor fragmented buffer struct fields and init flowTariq Toukan
Take struct mlx5_frag_buf out of mlx5_frag_buf_ctrl, as it is not needed to manage and control the datapath of the fragmented buffers API. struct mlx5_frag_buf contains control info to manage the allocation and de-allocation of the fragmented buffer. Its fields are not relevant for datapath, so here I take them out of the struct mlx5_frag_buf_ctrl, except for the fragments array itself. In addition, modified mlx5_fill_fbc to initialise the frags pointers as well. This implies that the buffer must be allocated before the function is called. A set of type-specific *_get_byte_size() functions are replaced by a generic one. Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
