* shift before cpu_to_le64(), not after it * writel() converts to l-e itself * misc missing conversions * in set_multicast() hash_table[] is host-endian; we feed it to card via writel() and populate it as host-endian, so we'd better put the first element into it also in host-endian * pci_unmap_single() et.al. expect host-endian, not little-endian Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk> Signed-off-by: NJeff Garzik <jeff@garzik.org>

* usb_control_message() to/from stack (breaks on e.g. arm); some places did kmalloc() for buffer, some just worked from stack. Added kmalloc()/memcpy()/kfree() in asix_read_cmd()/asix_write_cmd(), removed that crap from callers. * Fixed a leak in ax88172_bind() - on success it forgot to kfree() the buffer. * Endianness bug in ax88178_bind() - we read a word from eeprom and work with it without converting to host-endian Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk> Signed-off-by: NJeff Garzik <jeff@garzik.org>

txlo_dma_addr should be host-endian; we pass it to typhoon_tso_fill(), which does arithmetics on it, converts to l-e and passes it to card. Unfortunately, we forgot le32_to_cpu() when initializing it from face->txLoAddr, which sits in shared memory and is little-endian.

One cpu_to_le16() too many when passing argument for TYPHOON_CMD_XCVR_SELECT; we end up passing host-endian while the hardware expects little-endian. The other place doing that (typhoon_start_runtime()) does the right thing, so the card will recover at the next ifconfig up/tx timeout/resume, which limits the amount of mess, but still, WTF?

After reading the directory contents into the temporary buffer, we grab each dirent and pass it to filldir witht eh current offset of the dirent. The current offset was not being set for the first dirent in the temporary buffer, which coul dresult in bad offsets being set in the f_pos field result in looping and duplicate entries being returned from readdir.

This was broken by my '[XFS] simplify xfs_create/mknod/symlink prototype', which assigned the re-shuffled ondisk dev_t back to the rdev variable in xfs_vn_mknod. Because of that i_rdev is set to the ondisk dev_t instead of the linux dev_t later down the function. Fortunately the fix for it is trivial: we can just remove the assignment because xfs_revalidate_inode has done the proper job before unlocking the inode.

Andrew "Eagle Eye" Morton noticed that we use raw_local_save_flags() instead of raw_local_irq_save(flags) in die(). This allows the preemption of oopsing contexts - which is highly undesirable. It also causes CONFIG_DEBUG_PREEMPT to complain, as reported by Miles Lane. this bug was introduced via: commit 39743c9e Author: Andi Kleen <ak@suse.de> Date: Fri Oct 19 20:35:03 2007 +0200 x86: use raw locks during oopses - spin_lock_irqsave(&die.lock, flags); + __raw_spin_lock(&die.lock); + raw_local_save_flags(flags); that is not a correct open-coding of spin_lock_irqsave(): both the ordering is wrong (irqs should be disabled _first_), and the wrong flags-saving API was used.

When used function put_cmsg() to copy kernel information to user application memory, if the memory length given by user application is not enough, by the bad length calculate of msg.msg_controllen, put_cmsg() function may cause the msg.msg_controllen to be a large value, such as 0xFFFFFFF0, so the following put_cmsg() can also write data to usr application memory even usr has no valid memory to store this. This may cause usr application memory overflow. int put_cmsg(struct msghdr * msg, int level, int type, int len, void *data) { struct cmsghdr __user *cm = (__force struct cmsghdr __user *)msg->msg_control; struct cmsghdr cmhdr; int cmlen = CMSG_LEN(len); ~~~~~~~~~~~~~~~~~~~~~ int err; if (MSG_CMSG_COMPAT & msg->msg_flags) return put_cmsg_compat(msg, level, type, len, data); if (cm==NULL || msg->msg_controllen < sizeof(*cm)) { msg->msg_flags |= MSG_CTRUNC; return 0; /* XXX: return error? check spec. */ } if (msg->msg_controllen < cmlen) { ~~~~~~~~~~~~~~~~~~~~~~~~ msg->msg_flags |= MSG_CTRUNC; cmlen = msg->msg_controllen; } cmhdr.cmsg_level = level; cmhdr.cmsg_type = type; cmhdr.cmsg_len = cmlen; err = -EFAULT; if (copy_to_user(cm, &cmhdr, sizeof cmhdr)) goto out; if (copy_to_user(CMSG_DATA(cm), data, cmlen - sizeof(struct cmsghdr))) goto out; cmlen = CMSG_SPACE(len); ~~~~~~~~~~~~~~~~~~~~~~~~~~~ If MSG_CTRUNC flags is set, msg->msg_controllen is less than CMSG_SPACE(len), "msg->msg_controllen -= cmlen" will cause unsinged int type msg->msg_controllen to be a large value. ~~~~~~~~~~~~~~~~~~~~~~~~~~~ msg->msg_control += cmlen; msg->msg_controllen -= cmlen; ~~~~~~~~~~~~~~~~~~~~~ err = 0; out: return err; } The same promble exists in put_cmsg_compat().

Fix possible max_phys_segments violation in cloned dm-crypt bio. In write operation dm-crypt needs to allocate new bio request and run crypto operation on this clone. Cloned request has always the same size, but number of physical segments can be increased and violate max_phys_segments restriction. This can lead to data corruption and serious hardware malfunction. This was observed when using XFS over dm-crypt and at least two HBA controller drivers (arcmsr, cciss) recently. Fix it by using bio_add_page() call (which tests for other restrictions too) instead of constructing own biovec. All versions of dm-crypt are affected by this bug.
