gro: Normalise skb before bypassing GRO on netpoll VLAN path
Hi:
gro: Normalise skb before bypassing GRO on netpoll VLAN path
When we detect netpoll RX on the GRO VLAN path we bail out and
call the normal VLAN receive handler. However, the packet needs
to be normalised by calling eth_type_trans since that's what the
normal path expects (normally the GRO path does the fixup).
This patch adds the necessary call to vlan_gro_frags.

ext2: fix data corruption for racing writes
If two writers allocating blocks to file race with each other (e.g.
because writepages races with ordinary write or two writepages race with
each other), ext2_getblock() can be called on the same inode in parallel.
Before we are going to allocate new blocks, we have to recheck the block
chain we have obtained so far without holding truncate_mutex. Otherwise
we could overwrite the indirect block pointer set by the other writer
leading to data loss.
The below test program by Ying is able to reproduce the data loss with ext2
on in BRD in a few minutes if the machine is under memory pressure:
long kMemSize = 50 << 20;
int kPageSize = 4096;
int main(int argc, char **argv) {
int status;
int count = 0;
int i;
char *fname = "/mnt/test.mmap";
char *mem;
unlink(fname);
int fd = open(fname, O_CREAT | O_EXCL | O_RDWR, 0600);
status = ftruncate(fd, kMemSize);
mem = mmap(0, kMemSize, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
// Fill the memory with 1s.
memset(mem, 1, kMemSize);
sleep(2);
for (i = 0; i < kMemSize; i++) {
int byte_good = mem[i] != 0;
if (!byte_good && ((i % kPageSize) == 0)) {
//printf("%d ", i / kPageSize);
count++;

shmem: respect MAX_LFS_FILESIZE
SHMEM_MAX_BYTES was derived from the maximum size of its triple-indirect

Never mind 256kB pages, even 8kB pages on 32-bit kernels allowed files to
grow slightly bigger than that supposed maximum.
Fix this by using the min of both (at build time not run time). And it
happens that this calculation is good as far as 8MB pages on 32-bit or
16MB pages on 64-bit: though SHMSWP_MAX_INDEX gets truncated before that,
it's truncated to such large numbers that we don't need to care.

With 256kB PAGE_SIZE, the ENTRIES_PER_PAGEPAGE constant becomes too large

from 'unsigned long' to 'unsigned long long'.
Hugh: reverted its unsigned long longs in shmem_truncate_range() and
shmem_getpage(): the pagecache index cannot be more than an unsigned long,

initramfs: fix initramfs to work with hardlinked init
Change
cb6ff208076b5f434db1b8c983429269d719cef5 ("NOMMU: Support XIP on
initramfs") seems to have broken booting from initramfs with /sbin/init
being a hardlink.
It seems like the logic required for XIP on nommu, i.e. ftruncate to
reported cpio header file size (body_len) is broken for hardlinks, which
have a reported size of 0, and the truncate thus nukes the contents of the
file (in my case busybox), making boot impossible and ending with runaway
loop modprobe binfmt-0000 - and of course 0000 is not a valid binary
format.
My fix is to only call ftruncate if size is non-zero which fixes things
for me, but I'm not certain whether this will break XIP for those files on
nommu systems, although I would guess not.

Change ptrace_traceme() to not attach to the exiting ->real_parent. We

res_counter: update documentation
After the introduction of resource counters hierarchies
(
28dbc4b6a01fb579a9441c7b81e3d3413dc452df) the prototypes of
res_counter_init() and res_counter_charge() have been changed.
Keep the documentation consistent with the actual function prototypes.

spi: spi_write_then_read() bugfixes
The "simplify spi_write_then_read()" patch included two regressions from
the 2.6.27 behaviors:
- The data it wrote out during the (full duplex) read side
of the transfer was not zeroed.
- It fails completely on half duplex hardware, such as
Microwire and most "3-wire" SPI variants.
So, revert that patch. A revised version should be submitted at some
point, which can get the speedup on standard hardware (full duplex)
without breaking on less-capable half-duplex stuff.

signals: demultiplexing SIGTRAP signal
forgot to update the NSIGTRAP define in asm-generic/siginfo.h to the new
number of sigtrap subcodes. Nothing in the tree seems to use it, but
presumably something in user space might. So update it.
