hwmon: (coretemp) Add missing newline to dev_warn() message

2010-04-01T22:52:29Z

commit 4d7a5644e4adfafe76c2bd8ee168e3f3b5dae3a8 upstream. Add missing newline to dev_warn() message string. This is more of an issue with older kernels that don't automatically add a newline if it was missing from the end of the previous line.

USB: fix usbfs regression

2010-04-01T22:52:29Z

commit 7152b592593b9d48b33f8997b1dfd6df9143f7ec upstream. This patch (as1352) fixes a bug in the way isochronous input data is returned to userspace for usbfs transfers. The entire buffer must be copied, not just the first actual_length bytes, because the individual packets will be discontiguous if any of them are short.

2010-04-01T22:52:29Z

commit 926f2ae04f183098cf9a30521776fb2759c8afeb upstream. mpol_parse_str() made lots 'err' variable related bug. Because it is ugly and reviewing unfriendly. This patch simplifies it.

tmpfs: handle MPOL_LOCAL mount option properly

2010-04-01T22:52:28Z

commit 12821f5fb942e795f8009ece14bde868893bd811 upstream. commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in shmem_sb_info) added mpol=local mount option. but its feature is broken since it was born. because such code always return 1 (i.e. mount failure). This patch fixes it.

tmpfs: mpol=bind:0 don't cause mount error.

2010-04-01T22:52:28Z

commit d69b2e63e9172afb4d07c305601b79a55509ac4c upstream. Currently, following mount operation cause mount error. % mount -t tmpfs -ompol=bind:0 none /tmp Because commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in shmem_sb_info) corrupted MPOL_BIND parse code.

tmpfs: fix oops on mounts with mpol=default

2010-04-01T22:52:27Z

commit 413b43deab8377819aba1dbad2abf0c15d59b491 upstream. Fix an 'oops' when a tmpfs mount point is mounted with the mpol=default mempolicy. Upon remounting a tmpfs mount point with 'mpol=default' option, the mount code crashed with a null pointer dereference. The initial problem report was on 2.6.27, but the problem exists in mainline 2.6.34-rc as well. On examining the code, we see that mpol_new returns NULL if default mempolicy was requested. This 'NULL' mempolicy is accessed to store the node mask resulting in oops. The following patch fixes it.

b44 WOL setup: one-bit-off stack corruption kernel panic fix

2010-04-01T22:52:27Z

commit e0188829cb724e7d12a2d4e343b368ff1d6e1471 upstream. About 50% of shutdowns of b44 Ethernet adapter ends by kernel panic with kernels compiled with stack-protector. Checking b44_magic_pattern() return values, one call of b44_magic_pattern() returns 127. It means, that set_bit(128, pmask) was called on line 1509. It means that bit 0 of 17th byte of pmask was overwritten. But pmask has only 16 bytes. Stack corruption happens. It seems that set_bit() on line 1509 always writes one bit off. The fix does not only solve the stack corruption, but also makes Wake On LAN working on my onboard B44 on Asus A7V-333X mainboard. It seems that this problem affects all kernel versions since commit 725ad800 ([PATCH] b44: add wol for old nic) on 2006-06-20. Signed-off-by: Stanislav Brabec Signed-off-by: David S.

V4L/DVB (13961): em28xx-dvb: fix memleak in dvb_fini()

2010-04-01T22:52:27Z

commit 19f48cb105b7fa18d0dcab435919a3a29b7a7c4c upstream. this patch fixes a memory leak which occurs when an em28xx card with DVB extension is unplugged or its DVB extension driver is unloaded. In dvb_fini(), dev->dvb must be freed before being set to NULL, as is done in dvb_init() in case of error. Note that this bug is also present in the latest stable kernel release.
