commit 9b2761cb upstream. The maximum chunks used by the function is (SPI_AGGR_BUFFER_SIZE / WSPI_MAX_CHUNK_SIZE + 1). The original commands array had space for (SPI_AGGR_BUFFER_SIZE / WSPI_MAX_CHUNK_SIZE) commands. When the last chunk is used (len > 4 * WSPI_MAX_CHUNK_SIZE), the last command is stored outside the bounds of the commands array.

commit 4eeac22c upstream. In corner case for wl12xx_spi_raw_write() when len == SPI_AGGR_BUFFER_SIZE we don't setup correctly spi transfer_list. Next we will have garbage and strange errors reported by SPI framework (eg. wrong speed_hz, failed to transfer one message from queue) when iterate transfer_list. Signed-off-by:

commit d282e2b3 upstream. The initio driver has for many years had two copies of the same module device table. One of them is also used for registering the other driver, the other one is entirely useless after the large scale cleanup that Alan Cox did back in 2007. The compiler warns about this whenever the driver is built-in: drivers/scsi/initio.c:131:29: warning: 'i91u_pci_devices' defined but not used [-Wunused-variable] This removes the extraneous table and the warning.

commit 2ff56fad upstream. rc-main mistakenly uses #ifdef MODULE to determine whether it should load the rc keymap modules.

commit c9d57de6 upstream. When in FE_TUNE_MODE_ONESHOT the frontend must report the actual capabilities so user can take appropriate action. With frontends that can't do auto inversion this is done by dvb-core automatically so CAN_INVERSION_AUTO is valid. However, when in FE_TUNE_MODE_ONESHOT this is not true. So only set FE_CAN_INVERSION_AUTO in modes other than FE_TUNE_MODE_ONESHOT Signed-off-by:

commit f7e7868b upstream. Recently, i bought a blu-ray writer and noticed that while cdrecord worked perfectly, random writing didn't work on rewritable bd-re media. For example, dd if=/dev/zero of=/dev/sr0 bs=32768 count=2 gave the usual "read-only file system" message. After checking if the problem lies with my burner or firmware, i grep-ed the kernel source for EROFS. One of the results was in the cdrom driver. I tried to follow the function chain and ended in the cdrom_is_dvd_rw function where writing is permitted only for DVD-RAM and DVD+RW media. I added a new case label for 0x43 which is the profile name of BD-RE and now it works correctly for BD-RE too. Maybe there is a better way of implementing this, like a new function checking for blu-ray support and called from cdrom_open_write like it happens for mrw and dvdram media, but adding the case label worked. Thank you for your time. Signed-off-by:

commit 197c949e upstream. Backport of this upstream commit into stable kernels : 89c22d8c ("net: Fix skb csum races when peeking") exposed a bug in udp stack vs MSG_PEEK support, when user provides a buffer smaller than skb payload. In this case, skb_copy_and_csum_datagram_iovec(skb, sizeof(struct udphdr), msg->msg_iov); returns -EFAULT. This bug does not happen in upstream kernels since Al Viro did a great job to replace this into : skb_copy_and_csum_datagram_msg(skb, sizeof(struct udphdr), msg); This variant is safe vs short buffers. For the time being, instead reverting Herbert Xu patch and add back skb->ip_summed invalid changes, simply store the result of udp_lib_checksum_complete() so that we avoid computing the checksum a second time, and avoid the problematic skb_copy_and_csum_datagram_iovec() call. This patch can be applied on recent kernels as it avoids a double checksumming, then backported to stable kernels as a bug fix. Signed-off-by:

This reverts commit 127500d7. That fixed the problem of buffer over-reads introduced by backporting commit 89c22d8c ("net: Fix skb csum races when peeking"), but resulted in incorrect checksumming for short reads. It will be replaced with a complete fix. Signed-off-by:
