Drivers are allowed to set NETIF_F_SCTP_CSUM if they have hardware crc32c checksumming support for the SCTP protocol. Currently, NETIF_F_SCTP_CSUM flag is available in igb, ixgbe, i40e/i40evf drivers and for vlan devices. If we don't have NETIF_F_SCTP_CSUM then crc32c is done through CPU instructions, invoked from crypto layer, or if not available as slow-path fallback in software. Currently, loopback device propagates checksum offloading feature flags in dev->features, but is missing SCTP checksum offloading. Therefore, account for NETIF_F_SCTP_CSUM as well.

If a privileged user writes an empty string to /proc/net/pktgen/pgctrl the code for stripping the (then non-existent) '\n' actually writes the zero byte at index -1 of data[]. The then still uninitialized array will very likely fail the command matching tests and the pr_warning() at the end will therefore leak stack bytes to the kernel log. Fix those issues by simply ensuring we're passed a non-empty string as the user API apparently expects a trailing '\n' for all commands. Cc: "David S. Miller" <davem@davemloft.net> Signed-off-by:

Amir Vadai says: ==================== net/mlx4: Mellanox driver update 01-01-2014 This small patchset has a fix to a bogus usage of netif_get_num_default_rss_queues() in mlx4_en driver. Changes from V1: - Removed affinity_hint patch, to make it a generic instead of mlx specific Changes from V0: - Instead of reverting the netif_get_num_default_rss_queues() in mlx4_en, fixing it to limit the actual number of receive queues instead of limiting the number of IRQ's. Patchset was applied and tested against commit: cb6e926 "ipv6:fix checkpatch errors with assignment in if condition" ==================== Signed-off-by: -
Ido Shamay authored
This fix a performance bug introduced by commit 90b1ebe7 "mlx4: set maximal number of default RSS queues", which limits the numbers of IRQs opened by core module. The limit should be on the number of queues in the indirection table - rx_rings, and not on the number of IRQ's. Also, limiting on mlx4_core initialization instead of in mlx4_en, prevented using "ethtool -L" to utilize all the CPU's, when performance mode is prefered, since limiting this number to 8 reduces overall packet rate by 15%-50% in multiple TCP streams applications. For example, after running ethtool -L <ethx> rx 16 Packet rate Before the fix 897799 After the fix 1142070 Results were obtained using netperf: S=200 ; ( for i in $(seq 1 $S) ; do ( \ netperf -H 11.7.13.55 -t TCP_RR -l 30 &) ; \ wait ; done | grep "1 1" | awk '{SUM+=$6} END {print SUM}' ) CC: Yuval Mintz <yuvalmin@broadcom.com> Signed-off-by:

Steffen Klassert says: ==================== 1) Introduce skb_to_sgvec_nomark function to add further data to the sg list without calling sg_unmark_end first. Needed to add extended sequence number informations. From Fan Du. 2) Add IPsec extended sequence numbers support to the Authentication Header protocol for ipv4 and ipv6. From Fan Du. 3) Make the IPsec flowcache namespace aware, from Fan Du. 4) Avoid creating temporary SA for every packet when no key manager is registered. From Horia Geanta. 5) Support filtering of SA dumps to show only the SAs that match a given filter. From Nicolas Dichtel. 6) Remove caching of xfrm_policy_sk_bundles. The cached socket policy bundles are never used, instead we create a new cache entry whenever xfrm_lookup() is called on a socket policy. Most protocols cache the used routes to the socket, so this caching is not needed. 7) Fix a forgotten SADB_X_EXT_FILTER length check in pfkey, from Nicolas Dichtel. 8) Cleanup error handling of xfrm_state_clone. ==================== Signed-off-by:

Aaron Brown says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e and (mostly to) i40evf. Mitch provides most the work for this series. For the vf driver he requests a reset on a tx hang, removes vlan filtes on close since we already remove the MAC filters, fixes some crashes, gets rid of PCI DAC as it does not mean much on virtualized PCIe parts, skips assigning the device name that just gets renamed anyway, stores the descriptor ring size in a manner that allows the use of common tx and rx code with the PF driver and makes a handful of cosmetic fixes. For i40e he removes a delay left over from debugging and changes a do/while loop to a for loop to avoid hitting another delay each time. Catherine fixes inconsistent MSI and MSI-X messages and bumps the driver version. v2: Removed unnecessary periods and redundant OOM message. ==================== Signed-off-by: -
