Recently aded the use of skb_frag_dma_map to 3c59x, but didn't realize it automatically included the frag_offset internally, as well as provided an option to specify an extra offset in the parameter list. We need to specify an offset of 0 in the parameter list to avoid skb corruption that results in lost connections.

Noted that 3c59x has no checks on transmit for failed DMA mappings, and no ability to unmap fragments when a single map fails in the middle of a transmit. This patch provides error checking to ensure that dma mappings work properly, and unrolls an skb mapping if a fragmented skb transmission has a mapping failure to prevent leaks.

fix several issues in sparc BPF JIT compiler. ldx/stx related: . classic BPF instructions that access mem[] slots were not setting SEEN_MEM flag, so stack wasn't allocated. Fix that by advertising correct flags . LDX/STX instructions were missing SEEN_XREG, so register value could have leaked to user space. Fix it. . since stack for mem[] slots is allocated with 'sub %sp' instead of 'save %sp', use %sp as base register instead of %fp. . ldx mem[0] means first slot in classic BPF which should have -4 offset instead of 0. . sparc64 needs 2047 stack bias as per ABI to access stack . emit_stmem() was using LD32I macro instead of ST32I SKF_AD_VLAN_TAG* related: . SKF_AD_VLAN_TAG_PRESENT must return 1 or 0 instead of '> 0' or 0 as per classic BPF de facto standard . SKF_AD_VLAN_TAG needs to mask the field correctly Fixes: 2809a208 ("net: filter: Just In Time compiler for sparc") Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

There are other kconfig symbols which use SCSI_FC_ATTRS. In order to maintain sanity and prevent kconfig warnings, change all of these from using 'select' to using 'depends on' so that proper symbol dependencies will be honored and circular depends problems will be avoided. This fixes kconfig warnings and build errors: warning: (LIBFC && SCSI_IBMVFC && SCSI_QLA_FC && SCSI_LPFC && ZFCP && SCSI_BFA_FC && SCSI_CHELSIO_FCOE && FUSION_FC) selects SCSI_FC_ATTRS which has unmet direct dependencies (SCSI && NET) drivers/scsi/scsi_transport_fc.c: In function 'fc_host_post_event': drivers/scsi/scsi_transport_fc.c:543:7: error: 'scsi_nl_sock' undeclared (first use in this function) drivers/scsi/scsi_transport_fc.c: In function 'fc_host_post_vendor_event': drivers/scsi/scsi_transport_fc.c:611:7: error: 'scsi_nl_sock' undeclared (first use in this function) Reported-by: Fengguang Wu <fengguang.wu@intel.com> [0-day test robot] Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: David S.

Reported by Nikolay Aleksandrov. In efx_init_port() we call efx_mac_reconfigure() to work around a Falcon/A1 limitation, and this calls efx_{arch}_filter_sync_rx_mode(), which takes the addr_list_lock; but this lock is uninitialised, because we haven't called register_netdevice() yet. So, in efx_farch_filter_sync_rx_mode(), check efx_dev_registered() before doing anything else. The EF10 equivalent, efx_ef10_filter_sync_rx_mode(), already has the corresponding check.

Just like CNIC, tristate of these two modules is also dependent on IPV6. These need to be handled separately as they select CNIC, which can override tristate for CNIC from 'm' to 'y', which can cause build failures when ipv6 is compiled as a module even if CNIC's Kconfig will only 'm' or 'n' when ipv6 is compiled as a module.

Vlad Yasevich authored
Currently, it is possible to modify the vlan filter configuration to add pvid or untagged support. For example: bridge vlan add vid 10 dev eth0 bridge vlan add vid 10 dev eth0 untagged pvid The second statement will modify vlan 10 to include untagged and pvid configuration. However, it is currently impossible to go backwards bridge vlan add vid 10 dev eth0 untagged pvid bridge vlan add vid 10 dev eth0 Here nothing happens. This patch correct this so that any modifiers not supplied are removed from the configuration. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The bridge code checks if vlan filtering is enabled on both ingress and egress. When the state flip happens, it is possible for the bridge to currently be forwarding packets and forwarding behavior becomes non-deterministic. Bridge may drop packets on some interfaces, but not others. This patch solves this by caching the filtered state of the packet into skb_cb on ingress. The skb_cb is guaranteed to not be over-written between the time packet entres bridge forwarding path and the time it leaves it. On egress, we can then check the cached state to see if we need to apply filtering information. Signed-off-by: Vladislav Yasevich <vyasevic@redhat.com> Signed-off-by: David S.

The problem is that the slave is first linked and slave_cnt is incremented afterwards leading to a div by zero in the modes that use it as a modulus. What happens is that in bond_start_xmit() bond_has_slaves() is used to evaluate further transmission and it becomes true after the slave is linked in, but when slave_cnt is used in the xmit path it is still 0, so fetch it once and transmit based on that. Since it is used only in round-robin and XOR modes, the fix is only for them. Thanks to Eric Dumazet for pointing out the fault in my first try to fix this.

John W.

For the iwlwifi bits, Emmanuel says: "I re-enable scheduled scan on firmware that contain the fix for the bug that Linus reported. A few trivial fixes: endianity issues, the same DTIM period fix that I did in mac80211. Eyal fixes a few issues we identified with EAPOL, we now send them just as if they were management frames, this solves interrop issues. Johannes has another set of trivial fixes, while Luca fixes the way we configure the filters in the firmware. Last but not least, a new device is added by Oren." Emmanuel was traveling, resulting in his pull to be a bit larger than I would have liked to see at this point. FWIW, I have asked Emmanuel to be much more strict for any more pull requests in this cycle. In addition to the above, Sujith Manoharan reverts an earlier ath9k patch.

Usage count = 1 If we LEAVE_ANYCAST/close everything before rmmod'ing, there is no problem. We need to perform a cleanup similar to the one for multicast in addrconf_ifdown(how == 1).

Beniamino Galvani authored
In the current implementation the cleaning of tx ring is done by the NAPI poll handler, which is scheduled after rx interrupts. Thus, in absence of received packets the reclaim of used tx buffers is never executed, blocking further transmission. This can be easily reproduced starting the transmission of a UDP flow with iperf, which blocks almost immediately because skbs are not returned to the stack and the socket send buffer becomes full. The patch enables tx interrupts so that the tx reclaim is scheduled after completed transmissions.

This reverts commit 09ebb810. ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with the beacon interval. Before this commit, the sleepduration was never greater than the beacon interval. But now, the behavior has changed. For example, with an AP that uses a beacon interval of 100: ath: phy9: next beacon 61128704 ath: phy9: beacon period 204800 ath: phy9: DTIM period 204800 If the sleepduration is calculated based on the listen time, then the bmiss threshold should also be changed since the HW would be in sleep state for a longer time, but that is not done currently. To avoid configuring a higher beacon interval based on the sleepduration, revert to the original behavior. Power consumption is not a problem since PS is disabled in ath9k anyway.

Changing the vlan stripping policy of the QP isn't supported by older firmware versions for the INIT2RTR command. Nevertheless, we've used it. Fix that by doing this policy change using INIT2RTR only if the firmware supports it, otherwise, we call UPDATE_QP command to do the task.

The current wrapper implementation of the UPDATE_QP command tries to get the MAC index, even if MAC wasn't set by the VF. Fix it up to only handle the MAC field if it's valid.

When doing VGT->VST->VGT state changes, we used an incorrect mask for the vlan-stripping-disable (VSD) flag, hence the vlan related policy for user-space Raw Ethernet QPs open by VFs wasn't really applied. Fix that, by using the correct mask.

Single port VFs are seen PCI wise on both ports of the PF (we don't have single port PFs with ConnectX). With this in mind, it's possible for virtualization tools to try and configure a single ported VF through the "wrong" PF port. To handle that, we use the PF driver mapping of single port VFs to NIC ports and adjust the port value before calling into the low level code that does the actual VF configuration Fixes: 449fc488 ('net/mlx4: Adapt code for N-Port VF') Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.
