3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
commit d7178c79d9b7c5518f9943188091a75fc6ce0675 upstream.
According to the report from Slicky Devil, nilfs caused kernel oops at
nilfs_load_super_block function during mount after he shrank the
partition without resizing the filesystem:
BUG: unable to handle kernel NULL pointer dereference at 00000048

CR2: 0000000000000048
This turned out due to a defect in an error path which runs if the
calculated location of the secondary super block was invalid.
This patch fixes it and eliminates the reported oops.

3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anton Blanchard <anton@samba.org>
commit 2c724fb92732c0b2a5629eb8af74e82eb62ac947 upstream.
A read of a large file on an afs mount failed:
# cat junk.file > /dev/null
cat: junk.file: Bad message
Looking at the trace, call->offset wrapped since it is only an
unsigned short. In afs_extract_data:
_enter("{%u},{%zu},%d,,%zu", call->offset, len, last, count);
...
if (call->offset < count) {
if (last) {
_leave(" = -EBADMSG [%d < %zu]", call->offset, count);
return -EBADMSG;
}
Which matches the trace:
[cat ] ==> afs_extract_data({65132},{524},1,,65536)
[cat ] <== afs_extract_data() = -EBADMSG [0 < 65536]
call->offset went from 65132 to 0. Fix this by making call->offset an
unsigned int.

3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anton Blanchard <anton@samba.org>
commit c0173863528a8c9212c53e080d63a1aaae5ef4f4 upstream.
When writing files to afs I sometimes hit a BUG:
kernel BUG at fs/afs/rxrpc.c:179!
With a backtrace of:
afs_free_call
afs_make_call
afs_fs_store_data
afs_vnode_store_data
afs_write_back_from_locked_page
afs_writepages_region
afs_writepages
The cause is:
ASSERT(skb_queue_empty(&call->rx_queue));
Looking at a tcpdump of the session the abort happens because we
are exceeding our disk quota:
rx abort fs reply store-data error diskquota exceeded (32)
So the abort error is valid. We hit the BUG because we haven't
freed all the resources for the call.
By freeing any skbs in call->rx_queue before calling afs_free_call
we avoid hitting leaking memory and avoid hitting the BUG.

3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anton Blanchard <anton@samba.org>
commit b832796caa1fda8516464a003c8c7cc547bc20c2 upstream.
I have a workload where perf top scribbles over the stack and we SEGV.
What makes it interesting is that an snprintf is causing this.
The workload is a c++ gem that has method names over 3000 characters
long, but snprintf is designed to avoid overrunning buffers. So what
went wrong?
The problem is we assume snprintf returns the number of characters
written:
ret += repsep_snprintf(bf + ret, size - ret, "[%c] ", self->level);
...
ret += repsep_snprintf(bf + ret, size - ret, "%s", self->ms.sym->name);
Unfortunately this is not how snprintf works. snprintf returns the
number of characters that would have been written if there was enough
space. In the above case, if the first snprintf returns a value larger
than size, we pass a negative size into the second snprintf and happily
scribble over the stack. If you have 3000 character c++ methods thats a
lot of stack to trample.
This patch fixes repsep_snprintf by clamping the value at size - 1 which
is the maximum snprintf can write before adding the NULL terminator.
I get the sinking feeling that there are a lot of other uses of snprintf
that have this same bug, we should audit them all.

------------------
From: Eric Dumazet <eric.dumazet@gmail.com>
[ Upstream commit dfd25ffffc132c00070eed64200e8950da5d7e9d ]
commit ea4fc0d619 (ipv4: Don't use rt->rt_{src,dst} in ip_queue_xmit())
added a serious regression on synflood handling.
Simon Kirby discovered a successful connection was delayed by 20 seconds
before being responsive.
In my tests, I discovered that xmit frames were lost, and needed ~4
retransmits and a socket dst rebuild before being really sent.
In case of syncookie initiated connection, we use a different path to
initialize the socket dst, and inet->cork.fl.u.ip4 is left cleared.
As ip_queue_xmit() now depends on inet flow being setup, fix this by
copying the temp flowi4 we use in cookie_v4_check().

From: Stanislaw Gruszka <sgruszka@redhat.com>
commit 210787e82a0ac1ffb5d7be1c796f0c51050849ad upstream.
On il3945_down procedure we free tx queue data and nullify il->txq
pointer. After that we drop mutex and then cancel delayed works. There
is possibility, that after drooping mutex and before the cancel, some
delayed work will start and crash while trying to send commands to
the device. For example, here is reported crash in
il3945_bg_reg_txpower_periodic():
https://bugzilla.kernel.org/show_bug.cgi?id=42766#c10
Patch fix problem by adding il->txq check on works that send commands,
hence utilize tx queue.
