commit d79f16c046086f4fe0d42184a458e187464eb83e fixed a user triggerable scribble on free memory but added a new one which allows the user to scribble even more and user controlled data into freed space.

2016-01-06ethernet/atheros/alx: sanitize buffer sizing and paddingJarod Wilson3-12/+14
This is based on the work done by Przemek Rudy in bug 70761 at bugzilla.kernel.org, but with some work done to disentagle and clarify things a bit. Similar to Przemek's work and other drivers, we're adding a padding of 16 here, but we're also disentangling mtu size calculations from max buffer size calculations a bit, and adding ETH_HLEN to the value written into ALX_MTU. Hopefully, with a bit more consistency and clarity, things behave better here. Sadly, I can only test in my alx-driven E2200, which worked just fine before this patch. In comment #58 of bug 70761, Eugene A. Shatokhin reports that this patch does help considerably for a ROSA Linux user of his with an AR8162 network adapter when patched into a 4.1.x-based kernel, with several days of normal operation where wired network previously wasn't usable without setting MTU to 9000 as a work-around.

commit acf673a3187edf72068ee2f92f4dc47d66baed47 fixed a user triggerable free memory scribble but in doing so replaced it with a different one that allows the user to control the data and scribble even more. sixpack_close is called by the tty layer in tty context. The tty context is protected by sp_get() and sp_put(). However network layer activity via sp_xmit() is not protected this way.

2016-01-06mlxsw: pci: Adjust value of CPU egress traffic classIdo Schimmel1-1/+1
During initialization, when creating the send descriptor queues (SDQs), we specify the CPU egress traffic class of each SDQ. The maximum number of classes of this type is different in the two ASICs supported by this PCI driver. New firmware versions check this value is set correctly, which causes errors on the Spectrum ASIC, as its max exposed egress traffic class is lower than 7. Solve this by setting this field to 3, which is an acceptable value for both ASICs. Note that we currently do not expose the QoS capabilities of the ASICs, so setting this to an hardcoded value is OK for now.

This patch makes it possible to configure fman as a module as well so we don't change the status of PHYLIB in an allmodconfig kernel, and it adds a 'select PHYLIB' statement to ensure that phylib is always built-in when fman is. The driver uses "builtin_platform_driver(fman_driver);", which means it cannot be unloaded, but it's still possible to have it as a loadable module that gets loaded once and never removed.

2016-01-04bnxt_en: Separate bnxt_{rx|tx}_ring_info structs from bnxt_napi struct.Michael Chan2-86/+70
Currently, an rx and a tx ring are always paired with a completion ring. We want to restructure it so that it is possible to have a dedicated completion ring for tx or rx only. The bnxt hardware uses a completion ring for rx and tx events. The driver has to process the completion ring entries sequentially for the rx and tx events. Using a dedicated completion ring for rx only or tx only has these benefits: 1. A burst of rx packets can cause delay in processing tx events if the completion ring is shared. If tx queue is stopped by BQL, this can cause delay in re-starting the tx queue. 2. A completion ring is sized according to the rx and tx ring size rounded up to the nearest power of 2. When the completion ring is shared, it is sized by adding the rx and tx ring sizes and then rounded to the next power of 2, often with a lot of wasted space. 3. Using dedicated completion ring, we can adjust the tx and rx coalescing parameters independently for rx and tx. The first step is to separate the rx and tx ring structures from the bnxt_napi struct. In this patch, an rx ring and a tx ring will point to the same bnxt_napi struct to share the same completion ring. No change in ring assignment and mapping yet.

2015-12-31wlcore/wl18xx: fw logger over sdioShahar Patury13-128/+177
Enable the FW Logger to work over the SDIO interface in addition to over UART interface. In the new design we use fw internal memory instead of packet ram that was used in older (wl12xx) design. This change reduces the impact on TP and stability. A new event was added to notify fw logger is ready for reading. Dynamic configuration to debugfs was added as well.
