2012-02-25autofs: work around unhappy compat problem on x86-64Ian Kent
When the autofs protocol version 5 packet type was added in commit 5c0a32fc2cd0 ("autofs4: add new packet type for v5 communications"), it obvously tried quite hard to be word-size agnostic, and uses explicitly sized fields that are all correctly aligned. However, with the final "char name[NAME_MAX+1]" array at the end, the actual size of the structure ends up being not very well defined: because the struct isn't marked 'packed', doing a "sizeof()" on it will align the size of the struct up to the biggest alignment of the members it has. And despite all the members being the same, the alignment of them is different: a "__u64" has 4-byte alignment on x86-32, but native 8-byte alignment on x86-64. And while 'NAME_MAX+1' ends up being a nice round number (256), the name[] array starts out a 4-byte aligned. End result: the "packed" size of the structure is 300 bytes: 4-byte, but not 8-byte aligned. As a result, despite all the fields being in the same place on all architectures, sizeof() will round up that size to 304 bytes on architectures that have 8-byte alignment for u64. Note that this is *not* a problem for 32-bit compat mode on POWER, since there __u64 is 8-byte aligned even in 32-bit mode. But on x86, 32-bit and 64-bit alignment is different for 64-bit entities, and as a result the structure that has exactly the same layout has different sizes. So on x86-64, but no other architecture, we will just subtract 4 from the size of the structure when running in a compat task. That way we will write the properly sized packet that user mode expects. Not pretty. Sadly, this very subtle, and unnecessary, size difference has been encoded in user space that wants to read packets of *exactly* the right size, and will refuse to touch anything else.

2012-02-25[SCSI] osd_uld: Bump MAX_OSD_DEVICES from 64 to 1,048,576Boaz Harrosh
It used to be that minors where 8 bit. But now they are actually 20 bit. So the fix is simplicity itself. I've tested with 300 devices and all user-mode utils work just fine. I have also mechanically added 10,000 to the ida (so devices are /dev/osd10000, /dev/osd10001 ...) and was able to mkfs an exofs filesystem and access osds from user-mode. All the open-osd user-mode code uses the same library to access devices through their symbolic names in /dev/osdX so I'd say it's pretty safe. (Well tested) This patch is very important because some of the systems that will be deploying the 3.2 pnfs-objects code are larger than 64 OSDs and will stop to work properly when reaching that number.

2012-02-25sfc: Fix assignment of ip_summed for pre-allocated skbsBen Hutchings
When pre-allocating skbs for received packets, we set ip_summed = CHECKSUM_UNNCESSARY. We used to change it back to CHECKSUM_NONE when the received packet had an incorrect checksum or unhandled protocol. Commit bc8acf2c8c3e43fcc192762a9f964b3e9a17748b ('drivers/net: avoid some skb->ip_summed initializations') mistakenly replaced the latter assignment with a DEBUG-only assertion that ip_summed == CHECKSUM_NONE. This assertion is always false, but it seems no-one has exercised this code path in a DEBUG build. Fix this by moving our assignment of CHECKSUM_UNNECESSARY into efx_rx_packet_gro().

2012-02-24ppp: fix 'ppp_mp_reconstruct bad seq' errorsBen McKeegan
This patch fixes a (mostly cosmetic) bug introduced by the patch 'ppp: Use SKB queue abstraction interfaces in fragment processing' found here: http://www.spinics.net/lists/netdev/msg153312.html The above patch rewrote and moved the code responsible for cleaning up discarded fragments but the new code does not catch every case where this is necessary. This results in some discarded fragments remaining in the queue, and triggering a 'bad seq' error on the subsequent call to ppp_mp_reconstruct. Fragments are discarded whenever other fragments of the same frame have been lost. This can generate a lot of unwanted and misleading log messages. This patch also adds additional detail to the debug logging to make it clearer which fragments were lost and which other fragments were discarded as a result of losses.

2012-02-24sysfs: Fix memory leak in sysfs_sd_setsecdata().Masami Ichikawa
This patch fixies follwing two memory leak patterns that reported by kmemleak. sysfs_sd_setsecdata() is called during sys_lsetxattr() operation. It checks sd->s_iattr is NULL or not. Then if it is NULL, it calls sysfs_init_inode_attrs() to allocate memory. That code is this. iattrs = sd->s_iattr; if (!iattrs) iattrs = sysfs_init_inode_attrs(sd); The iattrs recieves sysfs_init_inode_attrs()'s result, but sd->s_iattr doesn't know the address. so it needs to set correct address to sd->s_iattr to free memory in other function. unreferenced object 0xffff880250b73e60 (size 32): comm "systemd", pid 1, jiffies 4294683888 (age 94.553s) hex dump (first 32 bytes): 73 79 73 74 65 6d 5f 75 3a 6f 62 6a 65 63 74 5f system_u:object_ 72 3a 73 79 73 66 73 5f 74 3a 73 30 00 00 00 00 r:sysfs_t:s0.... backtrace: [<ffffffff814cb1d0>] kmemleak_alloc+0x73/0x98 [<ffffffff811270ab>] __kmalloc+0x100/0x12c [<ffffffff8120775a>] context_struct_to_string+0x106/0x210 [<ffffffff81207cc1>] security_sid_to_context_core+0x10b/0x129 [<ffffffff812090ef>] security_sid_to_context+0x10/0x12 [<ffffffff811fb0da>] selinux_inode_getsecurity+0x7d/0xa8 [<ffffffff811fb127>] selinux_inode_getsecctx+0x22/0x2e [<ffffffff811f4d62>] security_inode_getsecctx+0x16/0x18 [<ffffffff81191dad>] sysfs_setxattr+0x96/0x117 [<ffffffff811542f0>] __vfs_setxattr_noperm+0x73/0xd9 [<ffffffff811543d9>] vfs_setxattr+0x83/0xa1 [<ffffffff811544c6>] setxattr+0xcf/0x101 [<ffffffff81154745>] sys_lsetxattr+0x6a/0x8f [<ffffffff814efda9>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff unreferenced object 0xffff88024163c5a0 (size 96): comm "systemd", pid 1, jiffies 4294683888 (age 94.553s) hex dump (first 32 bytes): 00 00 00 00 ed 41 00 00 00 00 00 00 00 00 00 00 .....A.......... 00 00 00 00 00 00 00 00 0c 64 42 4f 00 00 00 00 .........dBO.... backtrace: [<ffffffff814cb1d0>] kmemleak_alloc+0x73/0x98 [<ffffffff81127402>] kmem_cache_alloc_trace+0xc4/0xee [<ffffffff81191cbe>] sysfs_init_inode_attrs+0x2a/0x83 [<ffffffff81191dd6>] sysfs_setxattr+0xbf/0x117 [<ffffffff811542f0>] __vfs_setxattr_noperm+0x73/0xd9 [<ffffffff811543d9>] vfs_setxattr+0x83/0xa1 [<ffffffff811544c6>] setxattr+0xcf/0x101 [<ffffffff81154745>] sys_lsetxattr+0x6a/0x8f [<ffffffff814efda9>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff ` Signed-off-by: Masami Ichikawa <masami256@gmail.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-02-24USB: allow users to run setserial with cdc-acmOliver Neukum
We had a user report that running setserial on /dev/ttyACM0 didn't work. He pointed at an old patch by Oliver Neukum from 2008 that never went anywhere.. http://permalink.gmane.org/gmane.linux.usb.general/9236 I made some minor changes to get it to apply again, and got the user to retest on 3.1, and he reported it worked for him. https://bugzilla.redhat.com/show_bug.cgi?id=787607 The diff below is against 3.3rc. The only difference between this and the version the user tested is the removal of the if (!ACM_READY) test Havard removed ACM_READY in 99823f457d5994b3bd3775515578c8bfacc64b04 I'm unclear if there's need for a different test in its place.

2012-02-24cdc-wdm: Fix more races on the read pathBen Hutchings
We must not allow the input buffer length to change while we're shuffling the buffer contents. We also mustn't clear the WDM_READ flag after more data might have arrived. Therefore move both of these into the spinlocked region at the bottom of wdm_read(). When reading desc->length without holding the iuspin lock, use ACCESS_ONCE() to ensure the compiler doesn't re-read it with inconsistent results.

2012-02-24USB: qcserial: don't grab QMI port on Gobi 1000 devicesDan Williams
Gobi 1000 devices have a different port layout, which wasn't respected by the current driver, and thus it grabbed the QMI/net port. In the near future we'll be attaching another driver to the QMI/net port for these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver doesn't claim them. This patch also prevents qcserial from binding to interfaces 0 and 1 on 1K devices because those interfaces do not respond.

2012-02-24USB: serial: remove usb_serial_register and usb_serial_deregisterGreg Kroah-Hartman
No one uses them anymore, they should be using the safer usb_serial_register_drivers() and usb_serial_deregister_drivers() functions instead. Thanks to Alan Stern for writing these functions and porting all in-kernel users to them. Cc: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
