Commit fda48a0d (tcp: bind() fix when many ports are bound) introduced a bug on IPV6 part. We should not call ipv6_addr_any(inet6_rcv_saddr(sk2)) but ipv6_addr_any(inet6_rcv_saddr(sk)) because sk2 can be IPV4, while sk is IPV6. Reported-by:

The unpack routine fails to handle the decompress_method() returning unrecognised decompressor (compress_name == NULL). This results in the routine looping eventually oopsing on an out of bounds memory access. Note this bug is usually hidden, only triggering on trailing junk after one or more correct compressed blocks. The case of the compressed archive being complete junk is (by accident?) caught by the if (state != Reset) check because state is initialised to Start, but not updated due to the decompressor not having been called. Obviously if the junk is trailing a correctly decompressed buffer, state == Reset from the previous call to the decompressor. Signed-off-by:

This is a standalone version of VMware Balloon driver. Ballooning is a technique that allows hypervisor dynamically limit the amount of memory available to the guest (with guest cooperation). In the overcommit scenario, when hypervisor set detects that it needs to shuffle some memory, it instructs the driver to allocate certain number of pages, and the underlying memory gets returned to the hypervisor. Later hypervisor may return memory to the guest by reattaching memory to the pageframes and instructing the driver to "deflate" balloon. We are submitting a standalone driver because KVM maintainer (Avi Kivity) expressed opinion (rightly) that our transport does not fit well into virtqueue paradigm and thus it does not make much sense to integrate with virtio. There were also some concerns whether current ballooning technique is the right thing. If there appears a better framework to achieve this we are prepared to evaluate and switch to using it, but in the meantime we'd like to get this driver upstream. We want to get the driver accepted in distributions so that users do not have to deal with an out-of-tree module and many distributions have "upstream first" requirement. The driver has been shipping for a number of years and users running on VMware platform will have it installed as part of VMware Tools even if it will not come from a distribution, thus there should not be additional risk in pulling the driver into mainline. The driver will only activate if host is VMware so everyone else should not be affected at all. Signed-off-by:

We are seeing a large regression in database performance on recent kernels. The database opens a block device with O_DIRECT|O_SYNC and a number of threads write to different regions of the file at the same time. A simple test case is below. I haven't defined DEVICE since getting it wrong will destroy your data :) On an 3 disk LVM with a 64k chunk size we see about 17MB/sec and only a few threads in IO wait: procs -----io---- -system-- -----cpu------ r b bi bo in cs us sy id wa st 0 3 0 16170 656 2259 0 0 86 14 0 0 2 0 16704 695 2408 0 0 92 8 0 0 2 0 17308 744 2653 0 0 86 14 0 0 2 0 17933 759 2777 0 0 89 10 0 Most threads are blocking in vfs_fsync_range, which has: mutex_lock(&mapping->host->i_mutex); err = fop->fsync(file, dentry, datasync); if (!ret) ret = err; mutex_unlock(&mapping->host->i_mutex); commit 148f948b (vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode) offers some explanation of what is going on: Use these new helpers for syncing from generic VFS functions. This makes O_SYNC writes to block devices acquire i_mutex for syncing. If we really care about this, we can make block_fsync() drop the i_mutex and reacquire it before it returns. Thanks Jan for such a good commit message! As well as dropping i_mutex, Christoph suggests we should remove the call to sync_blockdev(): > sync_blockdev is an overcomplicated alias for filemap_write_and_wait on > the block device inode, which is exactly what we did just before calling > into ->fsync The patch below incorporates both suggestions. With it the testcase improves from 17MB/s to 68M/sec: procs -----io---- -system-- -----cpu------ r b bi bo in cs us sy id wa st 0 7 0 65536 1000 3878 0 0 70 30 0 0 34 0 69632 1016 3921 0 1 46 53 0 0 57 0 69632 1000 3921 0 0 55 45 0 0 53 0 69640 754 4111 0 0 81 19 0 Testcase: #define _GNU_SOURCE #include <stdio.h> #include <pthread.h> #include <unistd.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #define NR_THREADS 64 #define BUFSIZE (64 * 1024) #define DEVICE "/dev/mapper/XXXXXX" #define ALIGN(VAL, SIZE) (((VAL)+(SIZE)-1) & ~((SIZE)-1)) static int fd; static void *doit(void *arg) { unsigned long offset = (long)arg; char *b, *buf; b = malloc(BUFSIZE + 1024); buf = (char *)ALIGN((unsigned long)b, 1024); memset(buf, 0, BUFSIZE); while (1) pwrite(fd, buf, BUFSIZE, offset); } int main(int argc, char *argv[]) { int flags = O_RDWR|O_DIRECT; int i; unsigned long offset = 0; if (argc > 1 && !strcmp(argv[1], "O_SYNC")) flags |= O_SYNC; fd = open(DEVICE, flags); if (fd == -1) { perror("open"); exit(1); } for (i = 0; i < NR_THREADS-1; i++) { pthread_t tid; pthread_create(&tid, NULL, doit, (void *)offset); offset += BUFSIZE; } doit((void *)offset); return 0; } Signed-off-by:Anton Blanchard <anton@samba.org> Acked-by:

In this case, calling lzo1x_decompress_safe will fail, so we need to just use memcpy() instead (the upstream LZO code does something similar) - Since commit 54291362 ("initramfs: add missing decompressor error check") , the decompressor return code is checked in the init/initramfs.c The LZO decompressor didn't return the expected value, causing the initramfs code to falsely believe a decompression error occured Signed-off-by:

If a futex key happens to be located within a huge page mapped MAP_PRIVATE, get_futex_key() can go into an infinite loop waiting for a page->mapping that will never exist. See https://bugzilla.redhat.com/show_bug.cgi?id=552257 for more details about the problem. This patch makes page->mapping a poisoned value that includes PAGE_MAPPING_ANON mapped MAP_PRIVATE. This is enough for futex to continue but because of PAGE_MAPPING_ANON, the poisoned value is not dereferenced or used by futex. No other part of the VM should be dereferencing the page->mapping of a hugetlbfs page as its page cache is not on the LRU. This patch fixes the problem with the test case described in the bugzilla.

Description of patch: --------------------- This is a patch for the EFI framebuffer driver to enable the framebuffer of the NVIDIA 9400M as found in MacBook Pro (MBP) 5,1 and up. The framebuffer of the NVIDIA graphic cards are located at the following addresses in memory: 9400M: 0xC0010000 9600M GT: 0xB0030000 The patch delivered right here only provides the memory location of the framebuffer of the 9400M device. The 9600M GT is not covered. It is assumed that the 9400M is used when powered up the MBP. The information which device is currently powered and in use is stored in the 64 bytes large EFI variable "gpu-power-prefs". More specifically, byte 0x3B indicates whether 9600M GT (0x00) or 9400M (0x01) is online. The PCI bus IDs are the following: 9400M: PCI 03:00:00 9600M GT: PCI 02:00:00 The EFI variables can be easily read-out and manipulated with "rEFIt", an MBP specific bootloader tool. For more information on how handle rEFIt and EFI variables please consult "http://refit.sourceforge.net" and "http://ubuntuforums.org/archive/index.php/t-1076879.html". IMPORTANT NOTE: The information on how to activate the 9400M device given at "ubuntuforums.org" is not correct, since it states gpu-power-prefs[0x3B] = 0x00 -> 9400M (PCI 02:00:00) gpu-power-prefs[0x3B] = 0x01 -> 9600M GT (PCI 03:00:00) Actually, the assignment of the values and the PCI bus IDs are swapped. Suggestions: ------------ To cover framebuffers of both 9400M and 9600M GT, I would suggest to implement a conditional on "gpu-power-prefs". Depending on the value of byte 0x3B, the according framebuffer is selected. However, this requires kernel access to the EFI variables.

Commit 48b32a35 ("reiserfs: use generic xattr handlers") introduced a problem that causes corruption when extended attributes are replaced with a smaller value. The issue is that the reiserfs_setattr to shrink the xattr file was moved from before the write to after the write. The root issue has always been in the reiserfs xattr code, but was papered over by the fact that in the shrink case, the file would just be expanded again while the xattr was written. The end result is that the last 8 bytes of xattr data are lost. This patch fixes it to use new_size. Addresses https://bugzilla.kernel.org/show_bug.cgi?id=14826Signed-off-by:

Commit 677c9b2e ("reiserfs: remove privroot hiding in lookup") removed the magic from the lookup code to hide the .reiserfs_priv directory since it was getting loaded at mount-time instead. The intent was that the entry would be hidden from the user via a poisoned d_compare, but this was faulty. This introduced a security issue where unprivileged users could access and modify extended attributes or ACLs belonging to other users, including root. This patch resolves the issue by properly hiding .reiserfs_priv. This was the intent of the xattr poisoning code, but it appears to have never worked as expected. This is fixed by using d_revalidate instead of d_compare. This patch makes -oexpose_privroot a no-op. I'm fine leaving it this way. The effort involved in working out the corner cases wrt permissions and caching outweigh the benefit of the feature. Signed-off-by:
