misnamed.  They're accumulating bytes, not megabytes.

The statistic returned via /sys must be in megabytes, however,
which is what the HBA-API wants.  The FCP code needs to accumulate
it in bytes and then divide by 1,000,000 (not 2^20) before it
presented via sysfs.

This affects fcoe.ko only, not fnic.  The fnic driver
correctly by accumulating bytes and then converts to megabytes.

I checked that libhbalinux is using the /sys file directly without
conversion.

BTW, qla2xxx does divide by 2^20, which I'm not fixing here.

the scsi_host lock. This can lead to a variety of

[SCSI] libfc: fix NULL pointer dereference bug in fc_fcp_pkt_release

The back trace shows dead000000200200 in RAX, i.e., LIST_POISON2, indicating
that the fsp is already being dequeued, which is probably why no complaining
was seen in fc_fcp_destroy() about outstanding fsp not freed, since we dequeue
it in the end of fc_io_compl() before releasing it. The bug is due to the
fact that we have already destroyed lport's scsi_pkt_pool while on-going i/o
is still accessing it through fc_fcp_pkt_release(), like this trace or the
similar code path from scsi-ml to fc_eh_abort, etc. This is fixed by moving
the fc_fcp_destroy() after lport is detached from scsi-ml since fc_fcp_destroy
is supposed to called only once where no lport lock is taken, otherwise the

Luben Tuikov [Sat, 23 Oct 2010 04:24:36 +0000 (21:24 -0700)]
[SCSI] Retrieve the Caching mode page

Some kernel transport drivers unconditionally disable
retrieval of the Caching mode page. One such for example is
the BBB/CBI transport over USB.  Such a restraint is too
harsh as some devices do support the Caching mode
page. Unconditionally enabling the retrieval of this mode
page over those transports at their transport code level may
result in some devices failing and becoming unusable.

This patch implements a method of retrieving the Caching
mode page without unconditionally enabling it in the
transports which unconditionally disable it. The idea is to
ask for all supported pages, page code 0x3F, and then search
for the Caching mode page in the mode parameter data
returned. The sd driver already asks for all the mode pages
supported by the attached device by setting the page code to
0x3F in order to find out if the media is write protected by
reading the WP bit in the Device Specific Parameter
field. It then attempts to retrieve only the Caching mode
page by setting the page code to 8 and actually attempting
to retrieve it if and only if the transport allows it.

The method implemented here is that if the transport doesn't
allow retrieval of the Caching mode page and the device is
not RBC, then we ask for all pages supported by setting the
page code to 0x3F (similarly to how the WP bit is retrieved
above), and then we search for the Caching mode page in the
mode parameter data returned.

With this patch, devices over SATA, report this (no change):

install_special_mapping skips security_file_mmap check.

The install_special_mapping routine (used, for example, to setup the
vdso) skips the security check before insert_vm_struct, allowing a local
attacker to bypass the mmap_min_addr security restriction by limiting
the available pages for special mappings.

bprm_mm_init() also skips the check, and although I don't think this can
be used to bypass any restrictions, I don't see any reason not to have
the security check.
