2014-04-08isdnloop: several buffer overflowsDan Carpenter1-8/+9
There are three buffer overflows addressed in this patch. 1) In isdnloop_fake_err() we add an 'E' to a 60 character string and then copy it into a 60 character buffer. I have made the destination buffer 64 characters and I'm changed the sprintf() to a snprintf(). 2) In isdnloop_parse_cmd(), p points to a 6 characters into a 60 character buffer so we have 54 characters. The ->eazlist[] is 11 characters long. I have modified the code to return if the source buffer is too long. 3) In isdnloop_command() the cbuf[] array was 60 characters long but the max length of the string then can be up to 79 characters. I made the cbuf array 80 characters long and changed the sprintf() to snprintf(). I also removed the temporary "dial" buffer and changed it to use "p" directly. Unfortunately, we pass the "cbuf" string from isdnloop_command() to isdnloop_writecmd() which truncates anything over 60 characters to make it fit in card->omsg[]. (It can accept values up to 255 characters so long as there is a '\n' character every 60 characters). For now I have just fixed the memory corruption bug and left the other problems in this driver alone. Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: David S.

2014-04-08scripts: objdiff: detect object code changes between two commitsJason Cooper2-1/+142
objdiff is useful when doing large code cleanups. For example, when removing checkpatch warnings and errors from new drivers in the staging tree. objdiff can be used in conjunction with a git rebase to confirm that each commit made no changes to the resulting object code. It has the same return values as diff(1). This was written specifically to support adding the skein and threefish cryto drivers to the staging tree. I needed a programmatic way to confirm that commits changing >90% of the lines didn't inadvertently change the code. Temporary files (objdump output) are stored in /path/to/linux/.tmp_objdiff 'make mrproper' will remove this directory.

2014-04-08ASoC: fsl_sai: Fix Bit Clock Polarity configurationsNicolin Chen1-4/+4
The BCP bit in TCR4/RCR4 register rules as followings: 0 Bit clock is active high with drive outputs on rising edge and sample inputs on falling edge. 1 Bit clock is active low with drive outputs on falling edge and sample inputs on rising edge. For all formats currently supported in the fsl_sai driver, they're exactly sending data on the falling edge and sampling on the rising edge. However, the driver clears this BCP bit for all of them which results click noise when working with SGTL5000 and big noise with WM8962. Thus this patch corrects the BCP settings for all the formats here to fix the nosie issue.

Commit 8146875de7d4 (arm, kvm: Fix CPU hotplug callback registration) holds the lock before calling the two functions: kvm_vgic_hyp_init() kvm_timer_hyp_init() and both the two functions are calling register_cpu_notifier() to register cpu notifier, so cause double lock on cpu_add_remove_lock. Considered that both two functions are only called inside kvm_arch_init() with holding cpu_add_remove_lock, so simply use __register_cpu_notifier() to fix the problem.

2014-04-08ALSA: hda - Do not assign streams in reverse orderAnssi Hannula1-4/+5
Currently stream numbers are assigned in reverse order. Unfortunately commit 7546abfb8e1f9933b5 ("ALSA: hda - Increment default stream numbers for AMD HDMI controllers") assumed this was not the case (specifically, it had the "old cards had single device only" => "extra unused stream numbers do not matter" assumption), causing non-working audio regressions for AMD Radeon HDMI users. Change the stream numbers to be assigned in forward order. The benefit is that regular audio playback will still work even if the assumed stream count is too high, downside is that a too high stream count may remain hidden.

2014-04-08DRM: armada: fix corruption while loading cursorsRussell King1-0/+1
Loading cursors to the LCD controller's SRAM can be corrupted when the configured pixel clock is relatively slow. This seems to be caused when we write back-to-back to the SRAM registers. There doesn't appear to be any status register we can read to check when an access has completed. Inserting a dummy read between the writes appears to fix the problem.

2014-04-07arm64: add early_ioremap supportMark Salter11-52/+169
Add support for early IO or memory mappings which are needed before the normal ioremap() is usable. This also adds fixmap support for permanent fixed mappings such as that used by the earlyprintk device register region.

2014-04-07arm64: initialize pgprot info earlier in bootMark Salter3-2/+4
Presently, paging_init() calls init_mem_pgprot() to initialize pgprot values used by macros such as PAGE_KERNEL, PAGE_KERNEL_EXEC, etc. The new fixmap and early_ioremap support also needs to use these macros before paging_init() is called. This patch moves the init_mem_pgprot() call out of paging_init() and into setup_arch() so that pgprot_default gets initialized in time for fixmap and early_ioremap.
