In order to stop the RX path accessing the RX ring while it's being stopped or resized, we clear the interrupt mask (EESIPR) and then call free_irq() or synchronise_irq(). This is insufficient because the interrupt handler or NAPI poller may set EESIPR again after we clear it. Also, in sh_eth_set_ringparam() we currently don't disable NAPI polling at all. I could easily trigger a crash by running the loop: while ethtool -G eth0 rx 128 && ethtool -G eth0 rx 64; do echo -n .; done and 'ping -f' toward the sh_eth port from another machine. To fix this: - Add a software flag (irq_enabled) to signal whether interrupts should be enabled - In the interrupt handler, if the flag is clear then clear EESIPR and return - In the NAPI poller, if the flag is clear then don't set EESIPR - Set the flag before enabling interrupts in sh_eth_dev_init() and sh_eth_set_ringparam() - Clear the flag and serialise with the interrupt and NAPI handlers before clearing EESIPR in sh_eth_close() and sh_eth_set_ringparam() After this, I could run the loop for 100,000 iterations successfully.

We must only ever stop TX queues when they are full or the net device is not 'ready' so far as the net core, and specifically the watchdog, is concerned. Otherwise, the watchdog may fire *immediately* if no packets have been added to the queue in the last 5 seconds. What's more, sh_eth_tx_timeout() will likely crash if called while we're resizing the TX ring. I could easily trigger this by running the loop: while ethtool -G eth0 rx 128 && ethtool -G eth0 rx 64; do echo -n .; done Signed-off-by: NBen Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: NDavid S.

If an skb to be transmitted is shorter than the minimum Ethernet frame length, we currently set the DMA descriptor length to the minimum but do not add zero-padding. This could result in leaking sensitive data. We also pass different lengths to dma_map_single() and dma_unmap_single(). Use skb_padto() to pad properly, before calling dma_map_single().

In Dual EMAC, the default VLANs are used to segregate Rx packets between the ports, so adding the same default VLAN to the switch will affect the normal packet transfers. So returning error on addition of dual EMAC default VLANs. Even if EMAC 0 default port VLAN is added to EMAC 1, it will lead to break dual EMAC port separations.

When creating a bpf classifier in tc with priority collisions and invoking automatic unique handle assignment, cls_bpf_grab_new_handle() will return a wrong handle id which in fact is non-unique. Usually altering of specific filters is being addressed over major id, but in case of collisions we result in a filter chain, where handle ids address individual cls_bpf_progs inside the classifier. Issue is, in cls_bpf_grab_new_handle() we probe for head->hgen handle in cls_bpf_get() and in case we found a free handle, we're supposed to use exactly head->hgen. In case of insufficient numbers of handles, we bail out later as handle id 0 is not allowed.

In cls_bpf_modify_existing(), we read out the number of filter blocks, do some sanity checks, allocate a block on that size, and copy over the BPF instruction blob from user space, then pass everything through the classic BPF checker prior to installation of the classifier. We should reject mismatches here, there are 2 scenarios: the number of filter blocks could be smaller than the provided instruction blob, so we do a partial copy of the BPF program, and thus the instructions will either be rejected from the verifier or a valid BPF program will be run; in the other case, we'll end up copying more than we're supposed to, and most likely the trailing garbage will be rejected by the verifier as well (i.e. we need to fit instruction pattern, ret {A,K} needs to be last instruction, load/stores must be correct, etc); in case not, we would leak memory when dumping back instruction patterns. The code should have only used nla_len() as Dave noted to avoid this from the beginning. Anyway, lets fix it by rejecting such load attempts.

When registering a mdio bus, Linux assumes than every port has a PHY and tries to scan it. If a switch port has no PHY registered, DSA will fail to register the slave MII bus. To fix this, set the slave MII bus PHY mask to the switch PHYs mask. As an example, if we use a Marvell MV88E6352 (which is a 7-port switch with no registered PHYs for port 5 and port 6), with the following declared names: static struct dsa_chip_data switch_cdata = { [...] .port_names[0] = "sw0", .port_names[1] = "sw1", .port_names[2] = "sw2", .port_names[3] = "sw3", .port_names[4] = "sw4", .port_names[5] = "cpu", }; DSA will fail to create the switch instance. With the PHY mask set for the slave MII bus, only the PHY for ports 0-4 will be scanned and the instance will be successfully created.

Merge tag 'iwlwifi-for-kalle-2015-01-15' of https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-fixes * one fix for rfkill while scheduled scan is running. Linus's system hit this issue. WiFi would be unavailable after this has happpened because of bad state in cfg80211.
