- CVE-2015-0275 ext4: fallocate zero range page size > block size BUG (rhbz 1193907 1195178)
- Disable debugging options.

Yay for major version bumps :\.

We grab the full rc1 tarball instead of just the patch to make this way less
messy in the spec.  When 4.0 final is released, we'll need to undo a few
specific hacks.  Namely, we need to redefine:

upstream_sublevel
kversion
Source0

back to the standard definitions.

Thanks to Kyle for figuring this out 3 years ago.

Subject: [PATCH] ASLR: fix stack randomization on 64-bit systems
The issue is that the stack for processes is not properly randomized on 64 bit
architectures due to an integer overflow.
The affected function is randomize_stack_top() in file "fs/binfmt_elf.c":
static unsigned long randomize_stack_top(unsigned long stack_top)
{
unsigned int random_variable = 0;
if ((current->flags & PF_RANDOMIZE) &&
!(current->personality & ADDR_NO_RANDOMIZE)) {
random_variable = get_random_int() & STACK_RND_MASK;
random_variable <<= PAGE_SHIFT;
}
return PAGE_ALIGN(stack_top) + random_variable;
return PAGE_ALIGN(stack_top) - random_variable;
}
Note that, it declares the "random_variable" variable as "unsigned int". Since
the result of the shifting operation between STACK_RND_MASK (which is
0x3fffff on x86_64, 22 bits) and PAGE_SHIFT (which is 12 on x86_64):
random_variable <<= PAGE_SHIFT;
then the two leftmost bits are dropped when storing the result in the
"random_variable". This variable shall be at least 34 bits long to hold the
(22+12) result.
These two dropped bits have an impact on the entropy of process stack.
Concretely, the total stack entropy is reduced by four: from 2^28 to 2^30 (One
fourth of expected entropy).
This patch restores back the entropy by correcting the types involved in the
operations in the functions randomize_stack_top() and stack_maxrandom_size().
The successful fix can be tested with:
$ for i in `seq 1 10`; do cat /proc/self/maps | grep stack; done
7ffeda566000-7ffeda587000 rw-p 00000000 00:00 0 [stack]
7fff5a332000-7fff5a353000 rw-p 00000000 00:00 0 [stack]
7ffcdb7a1000-7ffcdb7c2000 rw-p 00000000 00:00 0 [stack]
7ffd5e2c4000-7ffd5e2e5000 rw-p 00000000 00:00 0 [stack]
...
Once corrected, the leading bytes should be between 7ffc and 7fff, rather
than always being 7fff.

Subject: [PATCH] ext4: Allocate entire range in zero range
Currently there is a bug in zero range code which causes zero range
calls to only allocate block aligned portion of the range, while
ignoring the rest in some cases.
In some cases, namely if the end of the range is past isize, we do
attempt to preallocate the last nonaligned block. However this might
cause kernel to BUG() in some carefully designed zero range requests on
setups where page size > block size.
Fix this problem by first preallocating the entire range, including the
nonaligned edges and converting the written extents to unwritten in the
next step. This approach will also give us the advantage of having the
range to be as linearly contiguous as possible.

Subject: [PATCH] ntp: Fixup adjtimex freq validation on 32bit systems
Additional validation of adjtimex freq values to avoid
potential multiplication overflows were added in commit
5e5aeb4367b (time: adjtimex: Validate the ADJ_FREQUENCY values)
Unfortunately the patch used LONG_MAX/MIN instead of
LLONG_MAX/MIN, which was fine on 64bit systems, but caused
false positives on 32bit systems resulting in most direct
frequency adjustments to fail w/ EINVAL.
ntpd only does driect frequency adjustments at startup,
so the issue was not easily observed there, but other sync
applications like ptpd and chrony were more effected by
the bug.

Subject: [PATCH] vhost/scsi: potential memory corruption
This code in vhost_scsi_make_tpg() is confusing because we limit "tpgt"
to UINT_MAX but the data type of "tpg->tport_tpgt" and that is a u16.
I looked at the context and it turns out that in
vhost_scsi_set_endpoint(), "tpg->tport_tpgt" is used as an offset into
the vs_tpg[] array which has VHOST_SCSI_MAX_TARGET (256) elements so
anything higher than 255 then it is invalid. I have made that the limit
now.
In vhost_scsi_send_evt() we mask away values higher than 255, but now
that the limit has changed, we don't need the mask.
