2020-11-09net/packet: make packet_fanout.arr size configurable up to 64KTanner Love
One use case of PACKET_FANOUT is lockless reception with one socket per CPU. 256 is a practical limit on increasingly many machines. Increase PACKET_FANOUT_MAX to 64K. Expand setsockopt PACKET_FANOUT to take an extra argument max_num_members. Also explicitly define a fanout_args struct, instead of implicitly casting to an integer. This documents the API and simplifies the control flow. If max_num_members is not specified or is set to 0, then 256 is used, same as before.

Merge procfs splice read fixes from Christoph Hellwig: "Greg reported a problem due to the fact that Android tests use procfs files to test splice, which stopped working with the changes for set_fs() removal. This series adds read_iter support for seq_file, and uses those for various proc files using seq_file to restore splice read support" [ Side note: Christoph initially had a scripted "move everything over" patch, which looks fine, but I personally would prefer us to actively discourage splice() on random files. So this does just the minimal basic core set of proc file op conversions. For completeness, and in case people care, that script was sed -i -e 's/\.proc_read\(\s*=\s*\)seq_read/\.proc_read_iter\1seq_read_iter/g' but I'll wait and see if somebody has a strong argument for using splice on random small /proc files before I'd run it on the whole kernel. - Linus ] * emailed patches from Christoph Hellwig <hch@lst.de>: proc "seq files": switch to ->read_iter proc "single files": switch to ->read_iter proc/stat: switch to ->read_iter proc/cpuinfo: switch to ->read_iter proc: wire up generic_file_splice_read for iter ops seq_file: add seq_read_iter

2020-11-06ext4: clean up the JBD2 API that initializes fast commitsHarshad Shirwadkar
This patch removes jbd2_fc_init() API and its related functions to simplify enabling fast commits. With this change, the number of fast commit blocks to use is solely determined by the JBD2 layer. So, we move the default value for minimum number of fast commit blocks from ext4/fast_commit.h to include/linux/jbd2.h. However, whether or not to use fast commits is determined by the file system. The file system just sets the fast commit feature using jbd2_journal_set_features(). JBD2 layer then determines how many blocks to use for fast commits (based on the value found in the JBD2 superblock). Note that the JBD2 feature flag of fast commits is just an indication that there are fast commit blocks present on disk. It doesn't tell JBD2 layer about the intent of the file system of whether to it wants to use fast commit or not. That's why, we blindly clear the fast commit flag in journal_reset() after the recovery is done.

2020-11-06jbd2: rename j_maxlen to j_total_len and add jbd2_journal_max_txn_bufsHarshad Shirwadkar
The on-disk superblock field sb->s_maxlen represents the total size of the journal including the fast commit area and is no more the max number of blocks available for a transaction. The maximum number of blocks available to a transaction is reduced by the number of fast commit blocks. So, this patch renames j_maxlen to j_total_len to better represent its intent. Also, it adds a function to calculate max number of bufs available for a transaction.

2020-11-06ext4: mark fc ineligible if inode gets evictied due to mem pressureHarshad Shirwadkar
If inode gets evicted due to memory pressure, we have to remove it from the fast commit list. However, that inode may have uncommitted changes that fast commits will lose. So, just fall back to full commits in this case. Also, rename the fast commit ineligiblity reason from "EXT4_FC_REASON_MEM" to "EXT4_FC_REASON_MEM_NOMEM" for better expression.

2020-11-06nexthop: Emit a notification when a nexthop is addedIdo Schimmel
Emit a notification in the nexthop notification chain when a new nexthop is added (not replaced). The nexthop can either be a new group or a single nexthop. The notification is sent after the nexthop is inserted into the red-black tree, as listeners might need to callback into the nexthop code with the nexthop ID in order to mark the nexthop as offloaded. A 'REPLACE' notification is emitted instead of 'ADD' as the distinction between the two is not important for in-kernel listeners. In case the listener is not familiar with the encoded nexthop ID, it can simply treat it as a new one. This is also consistent with the route offload API.

2020-11-06rtnetlink: Add RTNH_F_TRAP flagIdo Schimmel
The flag indicates to user space that the nexthop is not programmed to forward packets in hardware, but rather to trap them to the CPU. This is needed, for example, when the MAC of the nexthop neighbour is not resolved and packets should reach the CPU to trigger neighbour resolution. The flag will be used in subsequent patches by netdevsim to test nexthop objects programming to device drivers and in the future by mlxsw as well.

2020-11-06nexthop: Add nexthop notification data structuresIdo Schimmel
Add data structures that will be used for nexthop replace and delete notifications in the previously introduced nexthop notification chain. New data structures are added instead of passing the existing nexthop code structures directly for several reasons. First, the existing structures encode a lot of bookkeeping information which is irrelevant for listeners of the notification chain. Second, the existing structures can be changed without worrying about introducing regressions in listeners since they are not accessed directly by them. Third, listeners of the notification chain do not need to each parse the relatively complex nexthop code structures. They are passing the required information in a simplified way. Note that a single 'has_encap' bit is added instead of the actual encapsulation information since current listeners do not support such nexthops.

2020-11-06cfg80211: Add support to configure SAE PWE value to driversRohan Dutta
Add support to configure SAE PWE preference from userspace to drivers in both AP and STA modes. This is needed for cases where the driver takes care of Authentication frame processing (SME in the driver) so that correct enforcement of the acceptable PWE derivation mechanism can be performed. The userspace applications can pass the sae_pwe value using the NL80211_ATTR_SAE_PWE attribute in the NL80211_CMD_CONNECT and NL80211_CMD_START_AP commands to the driver. This allows selection between the hunting-and-pecking loop and hash-to-element options for PWE derivation. For backwards compatibility, this new attribute is optional and if not included, the driver is notified of the value being unspecified.
