selinux: properly handle multiple messages in selinux_netlink_send()

2020-05-05T17:13:25Z

commit fb73974172ffaaf57a7c42f35424d9aece1a5af6 upstream. Fix the SELinux netlink_send hook to properly handle multiple netlink messages in a single sk_buff; each message is parsed and subject to SELinux access control. Prior to this patch, SELinux only inspected the first message in the sk_buff.

ipv6: use READ_ONCE() for inet->hdrincl as in ipv4

2020-05-05T17:13:25Z

commit 59e3e4b52663a9d97efbce7307f62e4bc5c9ce91 upstream. As it was done in commit 8f659a03a0ba ("net: ipv4: fix for a race condition in raw_sendmsg") and commit 20b50d79974e ("net: ipv4: emulate READ_ONCE() on ->hdrincl bit-field in raw_sendmsg()") for ipv4, copy the value of inet->hdrincl in a local variable, to avoid introducing a race condition in the next commit.

ASoC: imx-spdif: Fix crash on suspend

2020-05-05T17:13:25Z

commit 9954859185c6e8359e71121037b627f1e294057d upstream. When registering a ASoC card the driver data of the parent device is set to point to the card. This driver data is used in the snd_soc_suspend()/resume() callbacks. The imx-spdif driver overwrites the driver data with custom data which causes snd_soc_suspend() to crash. Since the custom driver is not used anywhere simply deleting the line which sets the custom driver data fixes the issue.

ASoC: wm8960: Fix WM8960_SYSCLK_PLL mode

commit 6bb7451429084cefcb3a18fff809f7992595d2af upstream. With the introduction of WM8960_SYSCLK_AUTO mode, WM8960_SYSCLK_PLL mode was made unusable.

exynos4-is: fix a format string bug

2020-05-05T17:13:24Z

commit 76a563675485849f6f9ad5b30df220438b3628c1 upstream. Ironically, 7d4020c3c400 ("[media] exynos4-is: fix some warnings when compiling on arm64") fixed some format string bugs but introduced a new one. buf_index is a simple int, so it should be printed with %d, not %pad (which is correctly used for dma_addr_t).

perf/x86: Fix uninitialized value usage

2020-05-05T17:13:24Z

commit e01d8718de4170373cd7fbf5cf6f9cb61cebb1e9 upstream. When calling intel_alt_er() with .idx != EXTRA_REG_RSP_* we will not initialize alt_idx and then use this uninitialized value to index an array. When that is not fatal, it can result in an infinite loop in its caller __intel_shared_reg_get_constraints(), with IRQs disabled. Alternative error modes are random memory corruption due to the cpuc->shared_regs->regs[] array overrun, which manifest in either get_constraints or put_constraints doing weird stuff. Only took 6 hours of painful debugging to find this. Neither GCC nor Smatch warnings flagged this bug.

powerpc/perf: Remove PPMU_HAS_SSLOT flag for Power8

2020-05-05T17:13:24Z

commit 370f06c88528b3988fe24a372c10e1303bb94cf6 upstream. Commit 7a7868326d77 ("powerpc/perf: Add an explict flag indicating presence of SLOT field") introduced the PPMU_HAS_SSLOT flag to remove the assumption that MMCRA[SLOT] was present when PPMU_ALT_SIPR was not set. That commit's changelog also mentions that Power8 does not support MMCRA[SLOT]. However when the Power8 PMU support was merged, it errnoeously included the PPMU_HAS_SSLOT flag. So remove PPMU_HAS_SSLOT from the Power8 flags. mpe: On systems where MMCRA[SLOT] exists, the field occupies bits 37:39 (IBM numbering). On Power8 bit 37 is reserved, and 38:39 overlap with the high bits of the Threshold Event Counter Mantissa. I am not aware of any published events which use the threshold counting mechanism, which would cause the mantissa bits to be set. So in practice this bug is unlikely to trigger.
