[PATCH v2 1/1] xen-netback: process malformed sk_buff correctly to avoid BUG_ON()

The "BUG_ON(!frag_iter)" in function xenvif_rx_next_chunk() is triggered if the received sk_buff is malformed, that is, when the sk_buff has pattern (skb->data_len && !skb_shinfo(skb)->nr_frags). Below is a sample call stack: [ 438.652658] [ cut here ] [ 438.652660]

[patch 6/8] mtd: diskonchip: Allocate rs control per instance

The reed solomon library is moving the on stack decoder buffers into the rs control structure. That would break the DoC driver because multiple instances share the same control structure and can operate in parallel. At least in theory Instantiate a rs control instance per DoC device to avoid

[patch 8/8] rslib: Allocate decoder buffers to avoid VLAs

To get rid of the variable length arrays on stack in the RS decoder it's necessary to allocate the decoder buffers per control structure instance. All usage sites have been checked for potential parallel decoder usage and fixed where necessary. Kees confirmed that the pstore decoding is strictly

[patch 7/8] dm verity fec: Check result of init_rs()

The allocation of the reed solomon control structure can fail, but fec_alloc_bufs() ignores that and subsequent operations in dm verity use the potential NULL pointer unconditionally. Add a proper check and abort if init_rs() fails. Signed-off-by: Thomas Gleixner ---

[PATCH] usb: musb: Support gadget mode when the port is set to dual role

This allows dual-role ports to be reported as having gadget mode by the musb_has_gadget helper. This is required to enable MUSB at all with MUSB glue layers that set the port mode to MUSB_PORT_MODE_DUAL_ROLE at init. Most notably, this allows calling musb_start when needed in the virtual MUSB
