2011-10-25ceph: let the set_layout ioctl set single traitsGreg Farnum
Previously we were validating the passed-in stripe unit, object size, and stripe count against each other (and not testing most other stuff). Instead, make sure that the composed previous layout and new values are valid, and only send the new values to the MDS. This lets users change the pool without setting the whole layout, for instance.

2011-10-25Revert "ceph: don't truncate dirty pages in invalidate work thread"Sage Weil
This reverts commit c9af9fb68e01eb2c2165e1bc45cfeeed510c64e6. We need to block and truncate all pages in order to reliably invalidate them. Otherwise, we could: - have some uptodate pages in the cache - queue an invalidate - write(2) locks some pages - invalidate_work skips them - write(2) only overwrites part of the page - page now dirty and uptodate -> partial leakage of invalidated data It's not entirely clear why we started skipping locked pages in the first place. I just ran this through fsx and didn't see any problems. Signed-off-by: Sage Weil <sage@newdream.net>

Any non-masked msg allocation failure should generate a warning and stack trace to the console. All of these need to eventually be replaced by safe preallocation or msgpools. Signed-off-by: Sage Weil <sage@newdream.net>
2011-10-25libceph: don't complain on msgpool alloc failuresSage Weil
The pool allocation failures are masked by the pool; there is no need to spam the console about them. (That's the whole point of having the pool in the first place.) Mark msg allocations whose failure is safely handled as such. Signed-off-by: Sage Weil <sage@newdream.net>

2011-10-25ext4: prevent stack overrun in ext4_file_openDarrick J. Wong
In ext4_file_open, the filesystem records the mountpoint of the first file that is opened after mounting the filesystem. It does this by allocating a 64-byte stack buffer, calling d_path() to grab the mount point through which this file was accessed, and then memcpy()ing 64 bytes into the superblock's s_last_mounted field, starting from the return value of d_path(), which is stored as "cp". However, if cp > buf (which it frequently is since path components are prepended starting at the end of buf) then we can end up copying stack data into the superblock. Writing stack variables into the superblock doesn't sound like a great idea, so use strlcpy instead. Andi Kleen suggested using strlcpy instead of strncpy. Signed-off-by: Darrick J.

2011-10-25sysfs: Remove support for tagged directories with untagged members (again)Eric W. Biederman
In commit 8a9ea3237e7e ("Merge git://.../davem/net-next") where my sysfs changes from the net tree merged with the sysfs rbtree changes from Mickulas Patocka the conflict resolution failed to preserve the simplified property that was the point of my changes. That is sysfs_find_dirent can now say something is a match if and only s_name and s_ns match what we are looking for, and sysfs_readdir can simply return all of the directory entries where s_ns matches the directory that we should be returning. Now that we are back to exact matches we can tweak sysfs_find_dirent and the name rb_tree to order sysfs_dirents by s_ns s_name and remove the second loop in sysfs_find_dirent. However that change seems a bit much for a conflict resolution so it can come later. Signed-off-by: Eric W.

Function tt_response_fill_table() actually uses a tt_local_entry pointer to iterate either over the local or the global table entries (it depends on the what hash table is passed as argument). To iterate over such entries the hlist_for_each_entry_rcu() macro has to access their "hash_entry" field which MUST be at the same position in both the tt_global/local_entry structures.

2011-10-25ARM: i.MX28: shift frac value in _CLK_SET_RATEMatt Burtch
Noticed when setting SSP0 in clk_set_rate, _CLK_SET_RATE attempts to reset the clock divider for the SSP0 parent clock, in this case IO0FRAC. Bits 24-29 of HW_CLKCTRL_FRAC0 are cleared correctly, but when the new frac value is written the value isn't shifted up to write the correct bit-field. This results in IO0FRAC being set to 0 and CPUFRAC being corrupted. This should occur when writing IO1FRAC, EMIFRAC in HW_CLKCTRL_FRAC0 and GPMIFRAC, HSADCFRAC in HW_CLKCTRL_FRAC1. Tested on custom i.MX28 board with SSP0 SPI driver. Signed-off-by: Matt Burtch <matt@grid-net.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2011-10-25plat-mxc: iomux-v3.h: implicitly enable pull-up/down when that's desiredPaul Fertser
To configure pads during the initialisation a set of special constants is used, e.g. #define MX25_PAD_FEC_MDIO__FEC_MDIO IOMUX_PAD(0x3c4, 0x1cc, 0x10, 0, 0, PAD_CTL_HYS | PAD_CTL_PUS_22K_UP) The problem is that no pull-up/down is getting activated unless both PAD_CTL_PUE (pull-up enable) and PAD_CTL_PKE (pull/keeper module enable) set. This is clearly stated in the i.MX25 datasheet and is confirmed by the measurements on hardware. This leads to some rather hard to understand bugs such as misdetecting an absent ethernet PHY (a real bug i had), unstable data transfer etc. This might affect mx25, mx35, mx50, mx51 and mx53 SoCs. It's reasonable to expect that if the pullup value is specified, the intention was to have it actually active, so we implicitly add the needed bits.
