EU is not a valid country in db.txt file. Hence regulatory_hint returns failure if EEPROM provides region code as 0x30. Let's use FR for 0x30. Signed-off-by:

If device has already received country information from EEPROM, we won't parse AP's country IE and download it to firmware. We will also set regulatory flags to disable beacon hints and ignore country IE. Signed-off-by:

Driver gets country information from EEPROM during initialization. We will call regulatory_hint to update current regulatory domain. As by default world regulatory domain is selected by cfg80211, country '00' from EEPROM is ignored. Signed-off-by:

It's been observed that even if firmware returns an error for a configuration command, we go ahead and start AP. This patch changes the command type from async to sync so that threads waits for command response and return failure start AP. Signed-off-by:

Even if ADHOC start or join attempt is failed, these commands are returned with success status by firmware. Actual connection result is provided inside command response. This patch parses the adhoc connection result and resets connection state variables if connection is not successful. Signed-off-by:

This code was supposed to trigger a BUG() if we truncate the output but it's off by one so it allows one character to be truncated. Really drivers shouldn't call BUG_ON() and especially for something minor like this so I've changed it to a WARN_ON(). Signed-off-by:

Under heavy TX load, bnx2x_poll() can loop forever and trigger soft lockup bugs. A napi poll handler must yield after one TX completion round, risk of livelock is too high otherwise. Bug is very easy to trigger using a debug build, and udp flood, because of added cpu cycles in TX completion, and we do not receive enough packets to break the loop. Reported-by:

The patch 9497df88 ("rhashtable: Fix reader/rehash race") added a pair of barriers. In fact the wmb is superfluous because every subsequent write to the old or new hash table uses rcu_assign_pointer, which itself carriers a full barrier prior to the assignment. Therefore we may remove the explicit wmb. Signed-off-by:

Change mutual exclusion mechanism to prevent multiple threads of execution from running in service_ofldq() at the same time. The old mechanism used an implicit guard on the down-call path and none on the restart path and wasn't working. This checking makes the mechanism explicit and is much easier to understand as a result. Based on original work by Casey Leedom <leedom@chelsio.com> Signed-off-by:

In cgroup v1, dealing with cgroup membership was difficult because the number of membership associations was unbound. As a result, cgroup v1 grew several controllers whose primary purpose is either tagging membership or pull in configuration knobs from other subsystems so that cgroup membership test can be avoided. net_cls and net_prio controllers are examples of the latter. They allow configuring network-specific attributes from cgroup side so that network subsystem can avoid testing cgroup membership; unfortunately, these are not only cumbersome but also problematic. Both net_cls and net_prio aren't properly hierarchical. Both inherit configuration from the parent on creation but there's no interaction afterwards. An ancestor doesn't restrict the behavior in its subtree in anyway and configuration changes aren't propagated downwards. Especially when combined with cgroup delegation, this is problematic because delegatees can mess up whatever network configuration implemented at the system level. net_prio would allow the delegatees to set whatever priority value regardless of CAP_NET_ADMIN and net_cls the same for classid. While it is possible to solve these issues from controller side by implementing hierarchical allowable ranges in both controllers, it would involve quite a bit of complexity in the controllers and further obfuscate network configuration as it becomes even more difficult to tell what's actually being configured looking from the network side. While not much can be done for v1 at this point, as membership handling is sane on cgroup v2, it'd be better to make cgroup matching behave like other network matches and classifiers than introducing further complications. In preparation, this patch updates sock->sk_cgrp_data handling so that it points to the v2 cgroup that sock was created in until either net_prio or net_cls is used. Once either of the two is used, sock->sk_cgrp_data reverts to its previous role of carrying prioidx and classid. This is to avoid adding yet another cgroup related field to struct sock. As the mode switching can happen at most once per boot, the switching mechanism is aimed at lowering hot path overhead. It may leak a finite, likely small, number of cgroup refs and report spurious prioidx or classid on switching; however, dynamic updates of prioidx and classid have always been racy and lossy - socks between creation and fd installation are never updated, config changes don't update existing sockets at all, and prioidx may index with dead and recycled cgroup IDs. Non-critical inaccuracies from small race windows won't make any noticeable difference. This patch doesn't make use of the pointer yet. The following patch will implement netfilter match for cgroup2 membership. v2: Use sock_cgroup_data to avoid inflating struct sock w/ another cgroup specific field. v3: Add comments explaining why sock_data_prioidx() and sock_data_classid() use different fallback values.

Introduce sock->sk_cgrp_data which is a struct sock_cgroup_data. ->sk_cgroup_prioidx and ->sk_classid are moved into it. The struct and its accessors are defined in cgroup-defs.h. This is to prepare for overloading the fields with a cgroup pointer. This patch mostly performs equivalent conversions but the followings are noteworthy. * Equality test before updating classid is removed from sock_update_classid(). This shouldn't make any noticeable difference and a similar test will be implemented on the helper side later. * sock_update_netprioidx() now takes struct sock_cgroup_data and can be moved to netprio_cgroup.h without causing include dependency loop. Moved. * The dummy version of sock_update_netprioidx() converted to a static inline function while at it. Signed-off-by:

netprio builds per-netdev contiguous priomap array which is indexed by css->id. The array is allocated using kzalloc() effectively limiting the maximum ID supported to some thousand range. This patch caps the maximum supported css->id to USHRT_MAX which should be way above what is actually useable. This allows reducing sock->sk_cgrp_prioidx to u16 from u32. The freed up part will be used to overload the cgroup related fields. sock->sk_cgrp_prioidx's position is swapped with sk_mark so that the two cgroup related fields are adjacent. Signed-off-by:
