2014-08-02be2net: support deleting FW dump via ethtool (only for Lancer)Kalesh AP
This patch adds support to delete an existing FW-dump in Lancer via ethtool. Initiating a new dump is not allowed if a FW dump is already present in the adapter. The existing dump has to be first explicitly deleted. Signed-off-by: Kalesh AP <kalesh.purayil@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

Old versions of BE3 FW may not support cmds to re-provision (and hence optimize) resources/queues in SR-IOV config. Do not treat this FW cmd failure as fatal and fail the function initialization. Instead, just enable SR-IOV with the resources provided by the FW. Prior to the "create optimal number of queues on SR-IOV config" patch such failures were ignored.

2014-07-31ISDN: pcbit: off by one bugs in pcbit_set_msn()Dan Carpenter
1) We don't allocate enough space for the NUL terminator so we end up corrupting one character beyond the end of the buffer. 2) The "len - 1" should just be "len". The code is trying to copy a word from a buffer up to a comma or the last word in the buffer. Say you have the buffer, "foo,bar,baz", then this code truncates the last letter off each word so you get "fo", "ba", and "ba". You would hope this kind of bug would get noticed in testing... I'm not very familiar with this code and I can't test it, but I think we should copy the final character. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S.

2014-07-31sctp: Fixup v4mapped behaviour to comply with Sock APIJason Gunthorpe
The SCTP socket extensions API document describes the v4mapping option as follows: 8.1.15. Set/Clear IPv4 Mapped Addresses (SCTP_I_WANT_MAPPED_V4_ADDR) This socket option is a Boolean flag which turns on or off the mapping of IPv4 addresses. If this option is turned on, then IPv4 addresses will be mapped to V6 representation. If this option is turned off, then no mapping will be done of V4 addresses and a user will receive both PF_INET6 and PF_INET type addresses on the socket. See [RFC3542] for more details on mapped V6 addresses. This description isn't really in line with what the code does though. Introduce addr_to_user (renamed addr_v4map), which should be called before any sockaddr is passed back to user space. The new function places the sockaddr into the correct format depending on the SCTP_I_WANT_MAPPED_V4_ADDR option. Audit all places that touched v4mapped and either sanely construct a v4 or v6 address then call addr_to_user, or drop the unnecessary v4mapped check entirely. Audit all places that call addr_to_user and verify they are on a sycall return path. Add a custom getname that formats the address properly. Several bugs are addressed: - SCTP_I_WANT_MAPPED_V4_ADDR=0 often returned garbage for addresses to user space - The addr_len returned from recvmsg was not correct when returning AF_INET on a v6 socket - flowlabel and scope_id were not zerod when promoting a v4 to v6 - Some syscalls like bind and connect behaved differently depending on v4mapped Tested bind, getpeername, getsockname, connect, and recvmsg for proper behaviour in v4mapped = 1 and 0 cases.

Vince Bridgers says: ==================== net: stmmac: Improve mcast/ucast filter for snps This patch series adds Synopsys specific bindings for the Synopsys EMAC filter characteristics since those are implementation dependent. The multicast and unicast filtering code was improved to handle different configuration variations based on device tree settings. I verified the operation of the multicast and unicast filters through Synopsys support as requested during the V1 review, and tested the GMAC configuration on an Altera Cyclone 5 SOC (which supports 256 multicast bins and 128 Unicast addresses). The 10/100 variant of this driver modification was not tested, although it was compile tested. I shared the email thread results of the investigation through Synopsys with the stmmac maintainer. V4: Remove patch from series that addressed a sparse issue from a down rev'd version of sparse that does not show up in the latest version of sparse.

This patch adds and modifies code to support multiple Multicast and Unicast Synopsys MAC filter configurations. The default configuration is defined to support legacy driver behavior, which is 64 Multicast bins. The Unicast filter code previously assumed all controllers support 32 or 16 Unicast addresses based on controller version number, but this has been corrected to support a default of 1 Unicast address. The filter configuration may be specified through the devicetree using a Synopsys specific device tree entry. This information was verified with Synopsys through Synopsys Support Case #8000684337 and shared with the maintainer. Signed-off-by: Vince Bridgers <vbridgers2013@gmail.com> Signed-off-by: David S.

This change adds bindings for the number of multicast hash bins and perfect filter entries supported by the Synopsys EMAC. The Synopsys EMAC core is configurable at device creation time, and can be configured for a different number of multicast hash bins and a different number of perfect filter entries. The device does not provide a way to query these parameters, therefore parameters are required. The Altera Cyclone V SOC has support for 256 multicast hash bins and 128 perfect filter entries, and is different than what's currently provided in the stmmac driver.

2014-07-31net: stmmac: Correct set_filter for multicast and unicast casesVince Bridgers
This patch removes the check for the number of mulitcast addresses when using hash based filtering since it's not necessary. If the number of multicast addresses in the list exceeds the number of multicast hash bins, the bins will "fold" over into one of the bins configured and enabled for the particular component instance. The default number of maximum unicast addresses was changed from 32 to 1 since this number is not dependent on the component revision. The maximum number of multicast and unicast addresses is dependent on the configuration of the Synopsys EMAC configured by the SOC architect at the time the features were selected and configured for a particular component. Sadly, Synopsys does not provide a way to query the precise number supported by a particular component, so we must fall back on a devicetree entry. This configuration could vary from vendor to vendor (such as STMicro, Altera, etc). The multicast bins are set for every possible filtering case (including no entries) - previously the bits were set only if multicast filter entries were present.

As a result, a devicetree parameter is required in order for the driver to program these filters correctly for a particular device instance. This patch modifies the 10/100/1000 MAC software interface such that these configuration parameters can be set at initialization time.

This patch will add the msgbuf protocol. This protocol is used by the soon to be added new bus interface PCIe. Msgbuf is a protocol where most data is and remains located on the host (driver) side and transferred by DMA from and to device. Msgbuf is the protocol which takes care of the signalling of the buffers between host and device which identifies this DMA-able data.

2014-07-31brcmfmac: Do not use strcpy and strcatDaniel Kim
Commit "c1b2053 brcmfmac: Make firmware path a module parameter" introduced use of strcpy and strcat. The strcpy and strcat require using null terminated strings and can cause out-of-bounds memory access and subsequent corruption. This patch replaces these by strncpy and strncat respectively to assure array boundaries are not crossed.
