do_device_access() takes a separate parameter to indicate the direction of data transfer, which it used to use to select the appropriate function out of sg_pcopy_{to,from}_buffer(). However these two functions now have So this patch makes it bypass these wrappers and call the underlying function sg_copy_buffer() directly; this has the same calling style as do_device_access() i.e. a separate direction-of-transfer parameter and no pointers-to-const, so skipping the wrappers not only eliminates the warning, it also make the code simpler :) [akpm@linux-foundation.org: fix very broken build] Signed-off-by: NDave Gordon <david.s.gordon@intel.com> Acked-by: NArnd Bergmann <arnd@arndb.de> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The 'buf' parameter of sg(p)copy_from_buffer() can and should be const-qualified, although because of the shared implementation of _to_buffer() and _from_buffer(), we have to cast this away internally. This means that callers who have a 'const' buffer containing the data to be copied to the sg-list no longer have to cast away the const-ness themselves. It also enables improved coverage by code analysis tools. Signed-off-by: NDave Gordon <david.s.gordon@intel.com> Cc: Akinobu Mita <akinobu.mita@gmail.com> Cc: "Martin K.

The kerneldoc for the functions doesn't match the code; the last two parameters (buflen, skip) have been transposed, which is confusing, especially as they're both integral types and the compiler won't warn about swapping them. These functions and the kerneldoc were introduced in commit: df642cea lib/scatterlist: introduce sg_pcopy_from_buffer() ... Author: Akinobu Mita <akinobu.mita@gmail.com> Date: Mon Jul 8 16:01:54 2013 -0700 The only difference between sg_pcopy_{from,to}_buffer() and sg_copy_{from,to}_buffer() is an additional argument that specifies the number of bytes to skip the SG list before copying. The functions have the extra argument at the end, but the kerneldoc lists it in penultimate position.

In ipc_obtain_object_check we return -EIDRM when a bogus sequence number is detected via ipc_checkid, while the ipc manpages state the following return codes for such errors: EIDRM <ID> points to a removed identifier. EINVAL Invalid <ID> value, or unaligned, etc. EIDRM should only be returned upon a RMID call (->deleted check), and thus return EINVAL for wrong seq. This difference in semantics has also caused real bugs, ie: https://bugzilla.redhat.com/show_bug.cgi?id=246509Signed-off-by: NDavidlohr Bueso <dbueso@suse.de> Cc: Manfred Spraul <manfred@colorfullife.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The ipc_lock helper is used by all forms of sysv ipc to acquire the ipc object's spinlock. Upon error (bogus identifier), we always return -EINVAL, whether the problem be in the idr path or because we raced with a task performing RMID. For the later, however, all ipc related manpages, state the that for: EIDRM <ID> points to a removed identifier. And return: EINVAL Invalid <ID> value, or unaligned, etc. Which (EINVAL) should only return once the ipc resource is deleted. For all types of ipc this is done immediately upon a RMID command. However, shared memory behaves slightly different as it can merely mark a segment for deletion, and delay the actual freeing until there are no more active consumers. Per shmctl(IPC_RMID) manpage: "" Mark the segment to be destroyed. The segment will only actually be destroyed after the last process detaches it (i.e., when the shm_nattch member of the associated structure shmid_ds is zero). "" Unlike ipc_lock, paths that behave "correctly", at least per the manpage, involve controlling the ipc resource via *ctl(), doing the exact same validity check as ipc_lock after right acquiring the spinlock: if (!ipc_valid_object()) { err = -EIDRM; goto out_unlock; } Thus make ipc_lock consistent with the rest of ipc code and return -EIDRM in ipc_lock when !ipc_valid_object().

We currently use a full barrier on the sender side to to avoid receiver tasks disappearing on us while still performing on the sender side wakeup. We lack however, the proper CPU-CPU interactions pairing on the receiver side which busy-waits for the message. Similarly, we do not need a full smp_mb, and can relax the semantics for the writer and reader sides of the message. This is safe as we are only ordering loads and stores to r_msg. And in both smp_wmb and smp_rmb, there are no stores after the calls _anyway_. This obviously applies for pipelined_send and expunge_all, for EIRDM when destroying a queue.

This replaces the plain loop over the sglist array with for_each_sg() macro which consists of sg_next() function calls. Since arc doesn't select ARCH_HAS_SG_CHAIN, it is not necessary to use for_each_sg() in order to loop over each sg element. But this can help find problems with drivers that do not properly initialize their sg tables when CONFIG_DEBUG_SG is enabled.

If devpts failed to initialize, it would store an ERR_PTR in the global devpts_mnt. A subsequent open of /dev/ptmx would call devpts_new_index, which would dereference devpts_mnt and crash. Avoid storing invalid values in devpts_mnt; leave it NULL instead. Make both devpts_new_index and devpts_pty_new fail gracefully with ENODEV in that case, which then becomes the return value to the userspace open call on /dev/ptmx.
