The MDIO bus cannot be accessed at interrupt context, but on an FEC error, the fec_mpc52xx driver reset function also tries to reset the PHY. Since the error is detected at IRQ context, and the PHY functions try to sleep, the kernel ends up panicking. Resetting the PHY on an FEC error isn't even necessary. This patch solves the problem by removing the PHY reset entirely. Signed-off-by: NJohn Bonesio <bones@secretlab.ca> Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Signed-off-by: NDavid S.

The mechanism to clear the statistics register is dependent on the status of GMIIEN bit in MAC control register. If the GMIIEN bit is set, the stats registers are write to decrement. If the GMIIEN bit is cleared, the stats registers are plain read/write registers. The stats register clearing operation must take into account the current state of GMIIEN as it can be cleared when the interface is brought down. With existing implementation logic, querying for interface stats when the interface is down, can corrupt the statistics counters. This patch examines the GMIIEN bit status in MAC_CONTROL register before choosing an appropriate mask for clearing stats registers.

udp_poll() can in some circumstances drop frames with incorrect checksums. Problem is we now have to lock the socket while dropping frames, or risk sk_forward corruption. This bug is present since commit 95766fff ([UDP]: Add memory accounting.) While we are at it, we can correct ioctl(SIOCINQ) to also drop bad frames.

I was trying to use TCP_DEFER_ACCEPT and noticed that if the client does not talk, the connection is never accepted and remains in SYN_RECV state until the retransmits expire, where it finally is deleted. This is bad when some firewall such as netfilter sits between the client and the server because the firewall sees the connection in ESTABLISHED state while the server will finally silently drop it without sending an RST. This behaviour contradicts the man page which says it should wait only for some time : TCP_DEFER_ACCEPT (since Linux 2.4) Allows a listener to be awakened only when data arrives on the socket. Takes an integer value (seconds), this can bound the maximum number of attempts TCP will make to complete the connection. This option should not be used in code intended to be portable. Also, looking at ipv4/tcp.c, a retransmit counter is correctly computed : case TCP_DEFER_ACCEPT: icsk->icsk_accept_queue.rskq_defer_accept = 0; if (val > 0) { /* Translate value in seconds to number of * retransmits */ while (icsk->icsk_accept_queue.rskq_defer_accept < 32 && val > ((TCP_TIMEOUT_INIT / HZ) << icsk->icsk_accept_queue.rskq_defer_accept)) icsk->icsk_accept_queue.rskq_defer_accept++; icsk->icsk_accept_queue.rskq_defer_accept++; } break; ==> rskq_defer_accept is used as a counter of retransmits. But in tcp_minisocks.c, this counter is only checked. And in fact, I have found no location which updates it. So I think that what was intended was to decrease it in tcp_minisocks whenever it is checked, which the trivial patch below does. Signed-off-by: NWilly Tarreau <w@1wt.eu> Signed-off-by: NDavid S.

ieee80211_rx() must be called with softirqs disabled since the networking stack requires this for netif_rx() and some code in mac80211 can assume that it can not be processing its own tasklet and this call at the same time. It may be possible to remove this requirement after a careful audit of mac80211 and doing any needed locking improvements in it along with disabling softirqs around netif_rx(). An alternative might be to push all packet processing to process context in mac80211, instead of to the tasklet, and add other synchronisation.

When a scan completes, we call ieee80211_sta_find_ibss(), which is also called from other places. When the scan was done in software, there's no problem as both run from the single-threaded mac80211 workqueue and are thus serialised against each other, but with hardware scan the completion can be in a different context and race against callers of this function from the workqueue (e.g. due to beacon RX). So instead of calling ieee80211_sta_find_ibss() directly, just arm the timer and have it fire, scheduling the work, which will invoke ieee80211_sta_find_ibss() (if that is appropriate in the current state).
