2010-06-11Btrfs: prohibit a operation of changing acl's mask when noacl mount option usedShi Weihua1-0/+3
when used Posix File System Test Suite(pjd-fstest) to test btrfs, some cases about setfacl failed when noacl mount option used. I simplified used commands in pjd-fstest, and the following steps can reproduce it. ------------------------ # cd btrfs-part/ # mkdir aaa # setfacl -m m::rw aaa <- successed, but not expected by pjd-fstest. ------------------------ I checked ext3, a warning message occured, like as: setfacl: aaa/: Operation not supported Certainly, it's expected by pjd-fstest. So, i compared acl.c of btrfs and ext3. Based on that, a patch created. Fortunately, it works. Signed-off-by: Shi Weihua <[email protected]> Signed-off-by: Chris Mason <[email protected]>
2010-06-11Btrfs: should add a permission check for setfaclShi Weihua1-0/+3
On btrfs, do the following ------------------ # su user1 # cd btrfs-part/ # touch aaa # getfacl aaa # file: aaa # owner: user1 # group: user1 user::rw- group::rw- other::r-- # su user2 # cd btrfs-part/ # setfacl -m u::rwx aaa # getfacl aaa # file: aaa # owner: user1 # group: user1 user::rwx <- successed to setfacl group::rw- other::r-- ------------------ but we should prohibit it that user2 changing user1's acl. In fact, on ext3 and other fs, a message occurs: setfacl: aaa: Operation not permitted This patch fixed it.

2010-06-10net: deliver skbs on inactive slaves to exact matchesJohn Fastabend3-6/+20
Currently, the accelerated receive path for VLAN's will drop packets if the real device is an inactive slave and is not one of the special pkts tested for in skb_bond_should_drop(). This behavior is different then the non-accelerated path and for pkts over a bonded vlan. For example, vlanx -> bond0 -> ethx will be dropped in the vlan path and not delivered to any packet handlers at all. However, bond0 -> vlanx -> ethx and bond0 -> ethx will be delivered to handlers that match the exact dev, because the VLAN path checks the real_dev which is not a slave and netif_recv_skb() doesn't drop frames but only delivers them to exact matches. This patch adds a sk_buff flag which is used for tagging skbs that would previously been dropped and allows the skb to continue to skb_netif_recv(). Here we add logic to check for the deliver_no_wcard flag and if it is set only deliver to handlers that match exactly. This makes both paths above consistent and gives pkt handlers a way to identify skbs that come from inactive slaves. Without this patch in some configurations skbs will be delivered to handlers with exact matches and in others be dropped out right in the vlan path. I have tested the following 4 configurations in failover modes and load balancing modes. # bond0 -> ethx # vlanx -> bond0 -> ethx # bond0 -> vlanx -> ethx # bond0 -> ethx | vlanx -> -- Signed-off-by: John Fastabend <[email protected]> Signed-off-by: David S.

2010-06-10ceph: try to send partial cap release on cap message on missing inodeSage Weil3-5/+9
If we have enough memory to allocate a new cap release message, do so, so that we can send a partial release message immediately. This keeps us from making the MDS wait when the cap release it needs is in a partially full release message. If we fail because of ENOMEM, oh well, they'll just have to wait a bit longer.

cb->atapi.cdb is an array of 16 u8 elements. The call too memset() would set the first part of the sge array to zero as well. It's not a packed struct. This one has been around for five years. I found it with Smatch. I think the reason no one has seen it before is because we normally call sil24_fill_sg() and that overwrites sge with proper information?

2010-06-09gianfar: Revive the driver for eTSEC devices (disable timestamping)Anton Vorontsov1-2/+1
Since commit cc772ab7cdcaa24d1fae332d92a1602788644f7a ("gianfar: Add hardware RX timestamping support"), the driver no longer works on at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more boards as well). That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.
