A NULL pointer dereference may occur in __ceph_remove_cap with some of the
callbacks used in ceph_iterate_session_caps, namely trim_caps_cb and
remove_session_caps_cb. Those callers hold the session->s_mutex, so they
are prevented from concurrent execution, but ceph_evict_inode does not.
Since the callers of this function hold the i_ceph_lock, the fix is simply
a matter of returning immediately if caps->ci is NULL.

Ilya noticed that the first access to a blacklisted mount would often
get back -EACCES, but then subsequent calls would be OK. The problem is
in __do_request. If the session is marked as REJECTED, a hard error is
returned instead of waiting for a new session to come into being.
When the session is REJECTED and the mount was done with
recover_session=clean, queue the request to the waiting_for_map queue,
which will be awoken after tearing down the old session. We can only
do this for sync requests though, so check for async ones first and
just let the callers redrive a sync request.

When recovering a session (a'la recover_session=clean), we want to do
all of the operations that we do on a forced umount, but changing the
mount state to SHUTDOWN is can cause queued MDS requests to fail when
the session comes back. Most of those can idle until the session is
recovered in this situation.
Reserve SHUTDOWN state for forced umount, and make a new RECOVER state
for the forced reconnect situation. Change several tests for equality with
SHUTDOWN to test for that or RECOVER.

applications to populate protected regions of user code and data called
enclaves. Once activated, the new hardware protects enclave code and
data from outside access and modification.
Enclaves provide a place to store secrets and process data with those
secrets. SGX has been used, for example, to decrypt video without
exposing the decryption keys to nosy debuggers that might be used to
subvert DRM. Software has generally been rewritten specifically to
run in enclaves, but there are also projects that try to run limited
unmodified software in enclaves."

Change bpf_iter_task.c such that pointer to map_value may appear
on the stack for bpf_seq_printf() to access. Without previous
verifier patch, the bpf_iter test will fail.

Currently, when checking stack memory accessed by helper calls,
for spills, only PTR_TO_BTF_ID and SCALAR_VALUE are
allowed.
Song discovered an issue where the below bpf program
int dump_task(struct bpf_iter__task *ctx)
{
struct seq_file *seq = ctx->meta->seq;
static char[] info = "abc";
BPF_SEQ_PRINTF(seq, "%s\n", info);
return 0;
}
may cause a verifier failure.
The verifier output looks like:
; struct seq_file *seq = ctx->meta->seq;
1: (79) r1 = *(u64 *)(r1 +0)
; BPF_SEQ_PRINTF(seq, "%s\n", info);
2: (18) r2 = 0xffff9054400f6000
4: (7b) *(u64 *)(r10 -8) = r2
5: (bf) r4 = r10
;
6: (07) r4 += -8
; BPF_SEQ_PRINTF(seq, "%s\n", info);
7: (18) r2 = 0xffff9054400fe000
9: (b4) w3 = 4
10: (b4) w5 = 8
11: (85) call bpf_seq_printf#126
R1_w=ptr_seq_file(id=0,off=0,imm=0) R2_w=map_value(id=0,off=0,ks=4,vs=4,imm=0)
R3_w=inv4 R4_w=fp-8 R5_w=inv8 R10=fp0 fp-8_w=map_value
last_idx 11 first_idx 0
regs=8 stack=0 before 10: (b4) w5 = 8
regs=8 stack=0 before 9: (b4) w3 = 4
invalid indirect read from stack off -8+0 size 8
Basically, the verifier complains the map_value pointer at "fp-8" location.
To fix the issue, if env->allow_ptr_leaks is true, let us also permit
pointers on the stack to be accessible by the helper.

This release there are some fixes for longstanding problems, as well as
some cleanups:
- Fix a race condition where a duplicate filename could be created in an
encrypted directory if a syscall that creates a new filename raced
with the directory's encryption key being added.
- Allow deleting files that use an unsupported encryption policy.
- Simplify the locking for 'struct fscrypt_master_key'.
- Remove kernel-internal constants from the UAPI header.
As usual, all these patches have been in linux-next with no reported

raid10 discard optimizations having introduced potential for
corruption. Those reverts exposed a dm-raid.c compiler warning that
wasn't ever knowingly introduced. That min_not_zero() type mismatch
warning was thought to be safely fixed simply by changing 'struct
mddev' to use 'unsigned int' rather than int for chunk_sectors members
in that struct. I proposed either using a cast local to dm-raid.c but
thought changing the type to 'unsigned int' more correct. While that
may be, not enough testing was paired with code review associated with
making that change. As such we were left exposed and the result was a

Given that report, it is justified to simply revert these offending

this pull request just makes sure mainline does so too.

It was believed that metag was the only architecture that required the ring
buffer to keep 8 byte words aligned on 8 byte architectures, and with its
removal, it was assumed that the ring buffer code did not need to handle
this case. It appears that sparc64 also requires this.
The following was reported on a sparc64 boot up:
kernel: futex hash table entries: 65536 (order: 9, 4194304 bytes, linear)
