| | | | | | | | | | | | | | | | | | | | | | | | The change to iwch_provider.c in commit f4e91eb4 ("IB: convert struct class_device to struct device") undid the fix done in commit 7f049f2f ("RDMA/cxgb3: Hold rtnl_lock() around ethtool get_drvinfo call"). It removed the calls to rtnl_lock() that serialized the iw_cxgb3 ethtool ops calls into the cxgb3 driver. This locking is needed to avoid messing up the internal state of the cxgb3 driver.

Another thought is that individual pages might perhaps get evicted by VM pressure, in which case we might perhaps want to re-read not only the evicted page, but all subsequent pages too (in case the server returns more/less data per page so that the alignment of the next entry changes). We should therefore remove the condition that we only do this on page->index==0. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Actually, rounding is just wrong in this case, so use a mere division for a safe result. While at it, also: - give 'ide_palm_clk' variable a more suitable name; - get rid of the useless 'ideclkp' variable; - drop the LISP stype 'p' postfix from the 'clkp' variable's name. :-) Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: mcherkashin@ru.mvista.com Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* / / / Correct hash flushing from huge_ptep_set_wrprotect()David Gibson2008-07-082-6/+10
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Andy Whitcroft recently pointed out, the current powerpc version of huge_ptep_set_wrprotect() has a bug. It just calls ptep_set_wrprotect() which in turn calls pte_update() then hpte_need_flush() with the 'huge' argument set to 0. This will cause hpte_need_flush() to flush the wrong hash entries (of any). Andy's fix for this is already in the powerpc tree as commit 016b33c4958681c24056abed8ec95844a0da80a3. I have confirmed this is a real bug, not masked by some other synchronization, with a new testcase for libhugetlbfs. A process write a (MAP_PRIVATE) hugepage mapping, fork(), then alter the mapping and have the child incorrectly see the second write. Therefore, this should be fixed for 2.6.26, and for the stable tree. Here is a suitable patch for 2.6.26, which I think will also be suitable for the stable tree (neither of the headers in question has been changed much recently). It is cut down slighlty from Andy's original version, in that it does not include a 32-bit version of huge_ptep_set_wrprotect(). Currently, hugepages are not supported on any 32-bit powerpc platform. When they are, a suitable 32-bit version can be added - the only 32-bit hardware which supports hugepages does not use the conventional hashtable MMU and so will have different needs anyway.

Unfortunately it was also needed for cases other than eth_type_trans(). Adding it back. It's quite serious and may be a security risk as it causes a wrong input interface indication (the physical hdlcX instead of logical pvcX). Probably -stable class fix.

| * | bridge: fix use-after-free in br_cleanup_bridges()Patrick McHardy2008-07-031-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unregistering a bridge device may cause virtual devices stacked on the bridge, like vlan or macvlan devices, to be unregistered as well. br_cleanup_bridges() uses for_each_netdev_safe() to iterate over all devices during cleanup. This is not enough however, if one of the additionally unregistered devices is next in the list to the bridge device, it will get freed as well and the iteration continues on the freed element. Restart iteration after each bridge device removal from the beginning to fix this, similar to what rtnl_link_unregister() does.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent patch to legacy_serial.c factored out some code by using the of_match_node() facility to match a node against an array of possible matches. However, the patch didn't properly terminate the array causing potential crashes in cases where no match is found. In addition, the name of the array was poorly chosen for a static symbol making debugging harder.

* | | | vsprintf: add support for '%pS' and '%pF' pointer formatsLinus Torvalds2008-07-061-1/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | They print out a pointer in symbolic format, if possible (ie using symbolic KALLSYMS information). The '%pS' format is for regular direct pointers (which can point to data or code and that you find on the stack during backtraces etc), while '%pF' is for C function pointer types. On most architectures, the two mean exactly the same thing, but some architectures use an indirect pointer for C function pointers, where the function pointer points to a function descriptor (which in turn contains the actual pointer to the code). The '%pF' code automatically does the appropriate function descriptor dereference on such architectures. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | | | vsprintf: add infrastructure support for extended '%p' specifiersLinus Torvalds2008-07-061-2/+14

Right now it's just being ignored, but the next commit will start adding some specific pointer type extensions. NOTE! The reason the extension is appended to the '%p' is to allow minimal gcc type checking: gcc will still see the '%p' and will check that the argument passed in is indeed a pointer, and yet will not complain about the extended information that gcc doesn't understand about (on the other hand, it also won't actually check that the pointer type and the extension are compatible). Alphanumeric characters were chosen because there is no sane existing use for a string format with a hex pointer representation immediately followed by alphanumerics (which is what such a format string would have traditionally resulted in).
