By default, the rhashtable logic will fail to insert objects if the key-chains are too long and un-balanced. In the degenerate case where mac80211 is creating many virtual interfaces connected to the same peer(s), this case can happen. St insecure_elasticity to true to allow chains to grow as long as needed. Signed-off-by:

Johannes Berg authored
The original hand-implemented hash-table in mac80211 couldn't result in insertion errors, and while converting to rhashtable I evidently forgot to check the errors. This surfaced now only because Ben is adding many identical keys and that resulted in hidden insertion errors.

The min_def chanctx is affected not only by the current chandef, but sometimes also by other stations on the vif. There's a valid scenario where a TDLS peer can widen its BW, thereby causing the min_def to increase. Signed-off-by:

Arik Nemtsov authored
The previous approach simply ignored chandef restrictions when calculating the appropriate peer BW for a WIDER_BW peer. This could result in a regulatory violation if both peers indicated 80MHz support, but the regdomain forbade it. Change the approach to setting a WIDER_BW peer's BW. Don't exempt it from the chandef width at first. If during TDLS negotiation the chandef width is upgraded, update the peer's BW to match.

Even if the current chandef width is equal to the station's max-BW, it doesn't mean it's a valid width for TDLS. Make sure to always check regulatory constraints in these cases. Fixes: 0fabfaaf ("mac80211: upgrade BW of TDLS peers when possible") Signed-off-by:

Newer Fedora and OpenSUSE didn't boot with my standard configuration. It took me some time to figure out why, in fact I had to write a script to try different config options systematically. The problem is that something (systemd) in dracut depends on CONFIG_FHANDLE, which adds open by file handle syscalls. While it is set in defconfigs it is very easy to miss when updating older configs because it is not default y. Make it default y and also depend on EXPERT, as dracut use is likely widespread.

Commit bb29902a ("oom, oom_reaper: protect oom_reaper_list using simpler way") has simplified the check for tasks already enqueued for the oom reaper by checking tsk->oom_reaper_list != NULL. This check is not sufficient because the tsk might be the head of the queue without any other tasks queued and then we would simply lockup looping on the same task. Fix the condition by checking for the head as well. Fixes: bb29902a ("oom, oom_reaper: protect oom_reaper_list using simpler way") Signed-off-by:

The recently introduced batched invalidations mechanism uses its own mechanism for shootdown. However, it does wrong accounting of interrupts (e.g., inc_irq_stat is called for local invalidations), trace-points (e.g., TLB_REMOTE_SHOOTDOWN for local invalidations) and may break some platforms as it bypasses the invalidation mechanisms of Xen and SGI UV. This patch reuses the existing TLB flushing mechnaisms instead. We use NULL as mm to indicate a global invalidation is required.

Initially the phy_bus_name was added to manipulate the driver name but it was recently just used to manage the fixed-link and then to take some decision at run-time. So the patch uses the is_pseudo_fixed_link and removes the phy_bus_name variable not necessary anymore. The driver can manage the mdio registration by using phy-handle, dwmac-mdio and own parameter e.g. snps,phy-addr. This patch takes care about all these possible configurations and fixes the mdio registration in case of there is a real transceiver or a switch (that needs to be managed by using fixed-link).

Since the fix in f91ff5b9 ("net: sk_{detach|attach}_filter() rcu fixes") sk_attach_filter()/sk_detach_filter() now dereferences the filter with rcu_dereference_protected(), checking whether socket lock is held in control path. Since its introduction in 99405162 ("tun: socket filter support"), tap filters are managed under RTNL lock from __tun_chr_ioctl(). Thus the sock_owned_by_user(sk) doesn't apply in this specific case and therefore triggers the false positive. Extend the BPF API with __sk_attach_filter()/__sk_detach_filter() pair that is used by tap filters and pass in lockdep_rtnl_is_held() for the rcu_dereference_protected() checks instead. Reported-by:

ALSA system timer backend stops the timer via del_timer() without sync and leaves del_timer_sync() at the close instead. This is because of the restriction by the design of ALSA timer: namely, the stop callback may be called from the timer handler, and calling the sync shall lead to a hangup. However, this also triggers a kernel BUG() when the timer is rearmed immediately after stopping without sync: kernel BUG at kernel/time/timer.c:966! Call Trace: <IRQ> [<ffffffff8239c94e>] snd_timer_s_start+0x13e/0x1a0 [<ffffffff8239e1f4>] snd_timer_interrupt+0x504/0xec0 [<ffffffff8122fca0>] ? debug_check_no_locks_freed+0x290/0x290 [<ffffffff8239ec64>] snd_timer_s_function+0xb4/0x120 [<ffffffff81296b72>] call_timer_fn+0x162/0x520 [<ffffffff81296add>] ? call_timer_fn+0xcd/0x520 [<ffffffff8239ebb0>] ? snd_timer_interrupt+0xec0/0xec0 .... It's the place where add_timer() checks the pending timer. It's clear that this may happen after the immediate restart without sync in our cases. So, the workaround here is just to use mod_timer() instead of add_timer(). This looks like a band-aid fix, but it's a right move, as snd_timer_interrupt() takes care of the continuous rearm of timer.
