commit 5bbc097d upstream. This patch disables GartTlbWlk errors on AMD Fam10h CPUs if the BIOS forgets to do is (or is just too old). Letting these errors enabled can cause a sync-flood on the CPU causing a reboot. The AMD BKDG recommends disabling GART TLB Wlk Error completely. This patch is the fix for https://bugzilla.kernel.org/show_bug.cgi?id=33012 on my machine. Signed-off-by:

commit b87cf80a upstream. Support for Always Running APIC timer (ARAT) was introduced in commit db954b58. This feature allows us to avoid switching timers from LAPIC to something else (e.g. HPET) and go into timer broadcasts when entering deep C-states. AMD processors don't provide a CPUID bit for that feature but they also keep APIC timers running in deep C-states (except for cases when the processor is affected by erratum 400). Therefore we should set ARAT feature bit on AMD CPUs. Tested-by:

commit d78d671d upstream. Errata are defined using the AMD_LEGACY_ERRATUM() or AMD_OSVW_ERRATUM() macros. The latter is intended for newer errata that have an OSVW id assigned, which it takes as first argument. Both take a variable number of family-specific model-stepping ranges created by AMD_MODEL_RANGE(). Iff an erratum has an OSVW id, OSVW is available on the CPU, and the OSVW id is known to the hardware, it is used to determine whether an erratum is present. Otherwise, the model-stepping ranges are matched against the current CPU to find out whether the erratum applies. For certain special errata, the code using this framework might have to conduct further checks to make sure an erratum is really (not) present. Signed-off-by:

commit 78530bf7 upstream. This patch fixes severe UBIFS bug: UBIFS oopses when we 'fsync()' an file on R/O-mounter file-system. We (the UBIFS authors) incorrectly thought that VFS would not propagate 'fsync()' down to the file-system if it is read-only, but this is not the case. It is easy to exploit this bug using the following simple perl script: use strict; use File::Sync qw(fsync sync); die "File path is not specified" if not defined $ARGV[0]; my $path = $ARGV[0]; open FILE, "<", "$path" or die "Cannot open $path: $!"; fsync(\*FILE) or die "cannot fsync $path: $!"; close FILE or die "Cannot close $path: $!"; Thanks to Reuben Dowle <Reuben.Dowle@navico.com> for reporting about this issue.

The cause of this memleak is ramfs_nommu_expand_for_mapping() added page refcount to 2 which makes iput() can't free that pages.

commit c1d036c4 upstream. ia64_mca_cpu_init has a void *data local variable that is assigned the value from either __get_free_pages() or mca_bootmem(). The problem is that __get_free_pages returns an unsigned long and mca_bootmem, via alloc_bootmem(), returns a void *. format_mca_init_stack takes the void *, and it's also used with __pa(), but that casts it to long anyway. This results in the following build warning: arch/ia64/kernel/mca.c:1898: warning: assignment makes pointer from integer without a cast Cast the return of __get_free_pages to a void * to avoid the warning.

commit 70945643 upstream. Currently, we skip doing the is_path_accessible check in cifs_mount if there is no prefixpath. I have a report of at least one server however that allows a TREE_CONNECT to a share that has a DFS referral at its root. The reporter in this case was using a UNC that had no prefixpath, so the is_path_accessible check was not triggered and the box later hit a BUG() because we were chasing a DFS referral on the root dentry for the mount. This patch fixes this by removing the check for a zero-length prefixpath. That should make the is_path_accessible check be done in this situation and should allow the client to chase the DFS referral at mount time instead. Reported-and-Tested-by:

commit af24ee9e upstream. Commit 493f3358 added this call to xfs_fs_geometry() in order to avoid passing kernel stack data back to user space: + memset(geo, 0, sizeof(*geo)); Unfortunately, one of the callers of that function passes the address of a smaller data type, cast to fit the type that xfs_fs_geometry() requires. As a result, this can happen: Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: f87aca93 Pid: 262, comm: xfs_fsr Not tainted 2.6.38-rc6-493f3358+ #1 Call Trace: [<c12991ac>] ? panic+0x50/0x150 [<c102ed71>] ? __stack_chk_fail+0x10/0x18 [<f87aca93>] ? xfs_ioc_fsgeometry_v1+0x56/0x5d [xfs] Fix this by fixing that one caller to pass the right type and then copy out the subset it is interested in.

commit 1b1f693d upstream. As reported by Thomas Pollet, the rdma page counting can overflow. We get the rdma sizes in 64-bit unsigned entities, but then limit it to UINT_MAX bytes and shift them down to pages (so with a possible "+1" for an unaligned address). So each individual page count fits comfortably in an 'unsigned int' (not even close to overflowing into signed), but as they are added up, they might end up resulting in a signed return value. Which would be wrong. Catch the case of tot_pages turning negative, and return the appropriate error code. Reported-by:

commit 114279be upstream. Note: this patch targets 2.6.37 and tries to be as simple as possible. That is why it adds more copy-and-paste horror into fs/compat.c and uglifies fs/exec.c, this will be cleanuped later. compat_copy_strings() plays with bprm->vma/mm directly and thus has two problems: it lacks the RLIMIT_STACK check and argv/envp memory is not visible to oom killer. Export acct_arg_size() and get_arg_page(), change compat_copy_strings() to use get_arg_page(), change compat_do_execve() to do acct_arg_size(0) as do_execve() does. Add the fatal_signal_pending/cond_resched checks into compat_count() and compat_copy_strings(), this matches the code in fs/exec.c and certainly makes sense. Signed-off-by:

commit 3c77f845 upstream. Brad Spengler published a local memory-allocation DoS that evades the OOM-killer (though not the virtual memory RLIMIT): http://www.grsecurity.net/~spender/64bit_dos.c execve()->copy_strings() can allocate a lot of memory, but this is not visible to oom-killer, nobody can see the nascent bprm->mm and take it into account. With this patch get_arg_page() increments current's MM_ANONPAGES counter every time we allocate the new page for argv/envp. When do_execve() succeds or fails, we change this counter back. Technically this is not 100% correct, we can't know if the new page is swapped out and turn MM_ANONPAGES into MM_SWAPENTS, but I don't think this really matters and everything becomes correct once exec changes ->mm or fails.

commit fdac1e06 upstream. If the user-provided len is less than the expected offset, the IRLMP_ENUMDEVICES getsockopt will do a copy_to_user() with a very large size value. While this isn't be a security issue on x86 because it will get caught by the access_ok() check, it may leak large amounts of kernel heap on other architectures. In any event, this patch fixes it.

commit 22e76c84 upstream. We were using nlmsg_find_attr() to look up the bytecode by attribute when auditing, but then just using the first attribute when actually running bytecode. So, if we received a message with two attribute elements, where only the second had type INET_DIAG_REQ_BYTECODE, we would validate and run different bytecode strings. Fix this by consistently using nlmsg_find_attr everywhere. Signed-off-by:

commit 954032d2 upstream. This was noticed by users who performed more than 2^32 lock operations and hence made this counter overflow (eventually leading to use-after-free's). Setting rq_client to NULL here means that it won't later get auth_domain_put() when it should be. Appears to have been introduced in 2.5.42 by "[PATCH] kNFSd: Move auth domain lookup into svcauth" which moved most of the rq_client handling to common svcauth code, but left behind this one line.

commit 44cff8a9 upstream. Handle the rare case where a directory metadata block is uncompressed and corrupted, leading to a kernel oops in directory scanning (memcpy). Normally corruption is detected at the decompression stage and dealt with then, however, this will not happen if: - metadata isn't compressed (users can optionally request no metadata compression), or - the compressed metadata block was larger than the original, in which case the uncompressed version was used, or - the data was corrupt after decompression This patch fixes this by adding some sanity checks against known maximum values.
